Example 1

The maintenance section 9 of the overhead travelling crane rail 5 is additionally arranged on the overhead travelling crane rail 5 as shown in fig. 6, so that the original overhead travelling crane rail 5 is disconnected as shown in fig. 7 in the process of additionally arranging the maintenance section 9 to form a maintenance opening 8. The original cable in the crown block track 5 at the maintenance opening 8 is exposed and heave to form the external cable 3 due to the cutting of the crown block track 5 originally, and the crown block needs to lift the maintenance section 9 in the maintenance process, and at this time, the external cable 3 exposed to heave to interfere the lifting of the maintenance section 9, so that the normal lifting work of the maintenance section 9 is affected.

As shown in fig. 1, 8 and 13, an embodiment of the present invention provides a cable carrying mechanism 1, where the cable carrying mechanism 1 includes: a carrier 11 and a drive 12. The carrier member 11 is adapted to receive the external cable 3 exposed outside the service section 9 of the overhead travelling crane rail 5 and to move in a direction perpendicular to the direction of movement of the service section 9 of the overhead travelling crane rail 5 so that the external cable 3 can be carried away from the service section 9. The drive 12 is connected to the carrier 11 for driving the carrier 11 in a movement perpendicular to the direction of movement of the service section 9.

It is clear from the above that the external cable 3 is arranged on the bearing component 11, when the crown block needs to be overhauled, the driving device 12 drives the bearing component 11 to move after the crown block moves to the overhauling section 9, so that the external cable 3 is driven to be far away from the overhauling section 9 of the crown block track 5, and because the external cable 3 is far away from the overhauling section 9, the crown block positioned on the overhauling section 9 can not acquire the electromagnetic field and can not generate electric energy required by running to stay on the overhauling section 9, so that the crown block can move along with the overhauling section 9. At the same time, the outer cable 3 is supported by the bearing part 11 to be carried away from the overhauling section 9, so that the outer cable 3 cannot interfere with the crown block when the overhauling section 9 moves. And the motion track of the bearing part 11 is perpendicular to the motion direction of the overhaul section 9, so that the bearing part 11 cannot appear on the motion track of the overhaul section 9, namely, the external cable 3 is enabled to successfully avoid the overhaul section 9 and the crown block. In the process of overhauling, the cable bearing mechanism 1 is kept static, and the situation that the outer cable 3 does not interfere with the movement of the overhauling section 9 in the process that the overhauling section 9 is overhauled and returned is ensured. After the maintenance section 9 returns to the maintenance opening 8, the driving device 12 can drive the bearing component 11 and drive the external cable 3 to return to the initial position of the maintenance section 9, so that the external cable 3 can continuously supply power to the crown block on the crown block track 5, the problem that the maintenance section 9 cannot work normally due to the fact that the external cable 3 is heave around after the crown block track 5 is newly added with the maintenance section 9 is solved, meanwhile, the external cable 3 is borne by the cable bearing mechanism 1, so that the external cable 3 can supply power to the crown block when the crown block normally runs on the crown block track 5, the power supply control module 6 for the crown block movement of the maintenance section 9 is prevented from being additionally added, and the manufacturing cost is reduced.

The driving device 12, as shown in fig. 1 and 8, includes: the transmission assembly 122 is connected with the driving assembly 121, and the transmission assembly 122 is connected with the bearing part 11. The driving assembly 121 is connected with the transmission assembly 122, and is used for driving the transmission assembly 122, so that the transmission assembly 122 drives the bearing component 11 to move along the direction perpendicular to the movement direction of the overhaul section 9. The transmission assembly 122 is a linkage assembly that includes: a driving rod 1221, a driven rod 1222, and a driving rod 1223. The drive rod 1221 is connected to the carrier element 11 and moves in a direction perpendicular to the movement of the service section 9. The driven lever 1222 is rotatably connected to the driving lever 1221. The driving rod 1223 is rotatably connected to the driven rod 1222 for driving the driven rod 1222 to rotate, such that the driven rod 1222 drives the driving rod 1221 to move in a direction perpendicular to the movement direction of the service section 9. In some embodiments, the overhead crane rail 5 is fixed to the ceiling, and the service section 9 is lifted in the vertical direction, and the carrying members 11 and the service section 9 are suspended in parallel when the ceiling is connected to the overhead crane rail 5. When the drive assembly 121 drives the transmission assembly 122 in motion, the carrier 11 can move away from the service section 9 in a horizontal direction, which interfaces with the crown block rail 5. In order to be able to move the carrier 11 in a direction perpendicular to the direction of movement of the service section 9, the carrier 11 needs to be moved linearly in a fixed direction of movement. As will be clear from the above, the drive assembly 121 is capable of outputting a rotary motion, since the carrier 11 needs to be moved in a direction perpendicular to the direction of movement of the service section 9, i.e. the carrier 11 needs to be moved in a straight line. The transmission assembly 122 can convert the rotary motion of the driving assembly 121 into linear motion, so that the bearing part 11 can obtain the external force of the linear motion, and the avoidance work of the external cable 3 on the overhaul section 9 is realized. The driving component 121 is a motor with a speed reducer and a transmission shaft in this embodiment, an output shaft of the motor is connected with the transmission shaft and drives the transmission shaft to rotate, and the transmission shaft is rotatably connected to the transmission component 122. Further, the driving rod 1223 of the linkage assembly converts the rotational motion of the driving assembly 121 into a curvilinear motion of the end of the driving rod 1223, and the driven rod 1222 converts the curvilinear motion of the end of the driving rod 1223 into a linear motion. At this time, the driving rod 1221 is driven by the driven rod 1222 to perform linear motion along a fixed path, so that the bearing member 11 connected to the driving rod 1221 moves along a direction perpendicular to the movement direction of the service section 9, and conversion between rotational motion and linear motion is completed. In addition, the motion energy loss of the connecting rod assembly is small in the transmission process, the transmission process is stable, the motion track of the bearing part 11 is ensured, and the deviation in the motion engineering is avoided. In some embodiments, the overhead travelling crane rail 5 is fixed to the ceiling and the service section 9 is moved up and down in a vertical direction, with the load bearing members 11 and the service section 9 being arranged in parallel when the ceiling is connected to the overhead travelling crane rail 5. At this time, the driven rod 1222 is connected to the end of the driving rod 1221 at the same level as the maintenance section 9, the driving assembly 121 drives the driving rod 1223 to swing when working, and the end of the driving rod 1223 drives the end of the driven rod 1222 to move linearly in the level of the maintenance section 9. Driven by the driven lever 1222, the driving lever 1221 approaches or moves away from the service section 9 in a straight line in the same horizontal plane as the service section 9.

Meanwhile, as shown in fig. 1, in the present embodiment, two link assemblies are provided, which are disposed opposite to each other in the length direction of the bearing member 11, and two driving rods 1221 are connected by a connecting rod 1224.

As can be readily seen from the above, in this embodiment, the two sets of link assemblies are provided, and the motor has two output shafts, which are respectively rotatably connected to the driving rods 1223 of the two link assemblies. Both link assemblies simultaneously drive the carrier 11 to move under the drive of the drive assembly 121. The bearing part 11 moves more stably due to the external force on two sides, so that the external cable 3 arranged on the bearing part 11 is ensured not to fall off due to vibration of movement. Since the driving rods 1221 directly drive the bearing component 11 to move, the connecting rods 1224 connect the two driving rods 1221, so that the two driving rods 1221 can synchronously move, and the stability of the movement process of the bearing component 11 is ensured.

Further, in some embodiments, as shown in fig. 1,2, 3, 9, and 10, the transmission assembly 122 further includes: a guide member 1226. The guide member 1226 is slidably connected to the drive rod 1221 such that the drive rod 1221 is movable in a direction perpendicular to the direction of movement of the service section 9.

It is clear from the above that, in order to ensure that the carrier element 11 can be moved in a direction perpendicular to the movement of the service section 9, a avoidance of the external cable 3 when it is moved to the service section 9 is achieved. The linkage assembly effects a translation of the motion pattern during transmission, while the motion of the drive rod 1221 is dependent on the motion profile of the end of the driven rod 1222. Some motion errors are unavoidable due to installation or tolerances, resulting in deviations in the motion profile of the drive rod 1221. The guide member 1226 positions the driving rod 1221, guides the movement direction of the driving rod 1221 when it moves, corrects the movement direction of the guide member 1226, and ensures the movement locus of the carrier member 11. Further, in some embodiments, as shown in fig. 1, the guide member 1226 is a follower with a roller 1225, and in addition, as shown in fig. 1, the follower may be provided on a column, the driving rod 1221 is provided with a chute 0121 in a direction perpendicular to the movement direction of the service section 9, and the roller 1225 of the follower is rotatably provided in the chute 0121 for rotation when the driving rod 1221 slides in the direction perpendicular to the movement direction of the service section 9. The roller 1225 is rotatably arranged in the chute 0121 of the overhaul section 9, so that the positioning of the guide component 1226 to the driving rod 1221 is realized, the movement direction of the driving rod 1221 is ensured, and the roller 1225 rotates in the movement process of the driving rod 1221, so that the friction force between the roller 1225 and the driving rod 1221 is reduced, the movement of the driving rod 1221 is smoother, the abrasion in the chute 0121 is reduced, and the service life of the driving rod 1221 is prolonged.

As shown in fig. 2,3, 9 and 10, in some embodiments, when the link assembly moves the bearing member 11 along the movement direction perpendicular to the service section 9, the link assembly can change between the first movement state and the second movement state, and the cable bearing mechanism 1 further includes: and a detection module. The detection module is in communication connection with the main control module of the cable bearing mechanism 1 and is used for detecting the movement state of the connecting rod assembly when the bearing component 11 moves along the movement direction perpendicular to the overhaul section 9. The detection module is further configured to output a first electrical signal to the main control module when the link assembly moves to the first movement state, so that the main control module controls the driving assembly 121 to stop working, so that the bearing component 11 is stationary. The detection module is further configured to output a second electrical signal to the main control module when the link assembly moves to the second movement state, so that the main control module controls the driving assembly 121 to stop working, so that the bearing component 11 is stationary.

As can be readily seen from the above, when the link assembly is in the first movement state, the carrying member 11 can carry the external cable 3 to avoid the maintenance section 9, so that the maintenance section 9 can be lifted and lowered smoothly. When the connecting rod assembly is in the second movement state, the bearing part 11 can bear the external cable 3 to return to the initial position, so that the external cable 3 can supply power for the crown block on the overhauling section 9 after overhauling is completed. The bearing part 11 is driven by the connecting rod assembly to realize conversion of different motion states, so that the detection module detects different motion states of the connecting rod assembly, and the detection of the motion state of the connecting rod assembly can control the moving stroke of the bearing part 11. When the car track 5 needs to be overhauled, the bearing part 11 can be prevented from avoiding the overhauling section 9 through detection of the overhauling module, and at the moment, the overhauling section 9 can be smoothly lifted and lowered, so that interference with the external cable 3 can be avoided. The safety in the overhaul process is ensured, the lifting work of the overhaul section 9 is avoided when the connecting rod assembly does not reach the first motion state due to instructions or external interference factors, and the smooth operation of the overhaul process is ensured. Similarly, when the crown block is overhauled, the overhauling section 9 brings the crown block back to the maintenance opening 8 of the crown block track 5, at the moment, the driving assembly can drive the connecting rod assembly again, so that the connecting rod assembly moves to a second motion state, at the moment, the bearing part 11 can drive the external cable 3 under the transmission effect of the connecting rod assembly, so that the external cable 3 returns to the initial position of the overhauling section 9, power is supplied to the crown block on the crown block track 5, and the normal operation of the crown block on the crown block track 5 is ensured. The maintenance module can ensure that the bearing part 11 is returned to the initial state, and improves the working efficiency of crown block power supply.

As shown in fig. 2,3, 9, 10, and 11, the detection module includes: the first switching element 131 and the second switching element 132. The first switch 131 and the second switch 132 may be proximity switches or contact switches. The first switch element 131 is electrically connected to the main control module, and is configured to output a first electrical signal to the main control module when triggered. The second switching element 132 is electrically connected to the main control module, and is configured to output a second electrical signal to the main control module when triggered. The first switch element 131 is used for abutting against the active rod 1223 when the link assembly moves to the first movement state, and is triggered by the active rod 1223. The second switch element 132 is configured to abut against the driven lever 1222 when the link assembly moves to the second movement state, and is triggered by the driven lever 1222.

As is apparent from the above, the link assembly may exhibit different movement states during the movement of the transmission driving assembly 121, and it is known that the movement state of the bearing member 11 can be obtained by the movement state of the link assembly. It can thus be seen from fig. 2 that when the active rod 1223 of the connecting rod assembly is in contact with the first switching element 131, i.e. the connecting rod assembly is in the first movement state, it is indicated that the carrier 11 has moved to the target position, so that the service section 9 can be lifted off the external cable during lifting, avoiding interference between the service section 9 and the external cable 3 arranged on the carrier 11 during lifting. Furthermore, when the service section 9 has completed a service work back to the service opening 8 of the crown block rail 5, the external cable 3 located on the carrier member 11 needs to supply power to the crown block. As can be seen from fig. 3, when the driven lever 1222 of the link assembly is in contact with the second switch element 132, this indicates that the operating condition of the link assembly is such that the carrier member 11 is able to power the crown block on the service section 9. Further, the first switching element 131 and the second switching element 132 are only exemplified by a contact switch, and in other embodiments, other switching elements, such as a proximity switch, may be used for the first switching element 131 and the second switching element 132, which are not described in detail herein. Specifically, the first switching element 131 includes a switch body and a resiliently disposed contact switch, the contact switch being disposed toward the active rod 1223, and the contact switch being resilient in a direction perpendicular to the switch body. The second switching element 132 likewise comprises a switch body and a resiliently arranged contact switch, the contact switch of the second switching element 132 being arranged towards the driven lever 1222 and the contact switch being resilient in a direction perpendicular to the switch body. When the driving rod 1223 or the driven rod 1222 of the link assembly contacts the contact switch of the first switch element 131 or the second switch element 132 respectively, it indicates that the bearing component 11 has reached the required target position, at this time, the contacts of the contact switch are touched to generate a loop current, after the loop is communicated, the contact switch sends a signal to the main control module, and the main control module controls the driving assembly 121 to stop working, so that the bearing component 11 remains unchanged. Specifically, when the driving rod 1223 is driven by the driving component 121 to contact with the contact switch of the first switching element 131, the contact switch triggers the circuit of the first switching element 131 to form a closed loop, and sends a signal to the main control module, the main control module controls the driving component 121 to stop working so that the bearing component 11 remains stationary, and at this time, the connecting rod component moves to the first movement state, and the bearing component 11 has borne the external cable 3 to finish avoidance. When the driven rod 1222 is driven by the driving rod 1223 to contact with the contact switch of the second switch element 132, the contact switch triggers the circuit of the second switch element 132 to form a closed loop, and sends a signal to the main control module, which controls the driving assembly 121 to stop working, so that the bearing component 11 remains stationary, and the connecting rod assembly moves to the second movement state, where the bearing component 11 has borne the external cable 3 and returns to the initial position of the maintenance section 9, so that the external cable 3 supplies power to the overhead crane rail 5 normally. The contact switch ensures the accuracy of detection through mechanical detection, and further ensures the normal operation of the cable bearing mechanism 1.

Finally, as shown in fig. 1, the bearing component 11 is a cable supporting plate, and a mounting groove is formed in one side of the cable supporting plate, which is close to the overhaul section 9, and extends along the length direction of the cable supporting plate, so as to accommodate the external cable 3.

As can be readily seen from the foregoing, the cable support plate is relatively lightweight, reducing the load on the output of the drive 12. Meanwhile, the bearing part 11 bears the external cable 3 in the using process and avoids the external cable 3 when the overhaul section 9 works, so that the mounting groove can realize better mounting of the external cable 3, the part of the external cable 3 can be embedded into the mounting groove, the danger that the bearing part 11 is separated from the bearing part 11 when the bearing part 11 works for a long time is avoided, and the working stability of the cable bearing mechanism 1 is ensured.

Example 2

As shown in fig. 7, an embodiment of the present invention provides an overhead traveling crane rail assembly including: crown block track 5, cable assembly and cable bearing mechanism 1. The overhead traveling crane track 5 is used for setting up the overhead traveling crane, makes the overhead traveling crane can slide on overhead traveling crane track 5, and overhead traveling crane track 5 includes: a fixed section provided with a maintenance opening 8, a maintenance section 9 which can be moved out of or into the maintenance opening 8; when the crown block slides to the maintenance section 9, the maintenance section 9 is used for driving the crown block to move out of the maintenance opening 8 together when moving out of the maintenance opening 8. The cable assembly includes: an inner cable penetrating the fixed section and an outer cable 3 connected with the inner cable; wherein the external cable 3 bypasses the service opening 8 and is exposed outside the service section 9; the cable assembly is also externally connected with a power supply control module 6 and is used for supplying power to the crown block after power is obtained, so that the crown block arranged on the crown block track 5 can be driven. The carrier member 11 of the cable carrier mechanism 1 receives an external cable 3.

As can be readily seen from the above, the crown block track 5 is used for the crown block to be movable therealong for the transport of articles. The cable assembly is arranged inside the crown block track 5 and is externally connected with a power supply control module, the cable assembly can generate uniform electromagnetic fields on the crown block track 5 after being electrified through the current magnetic effect, each crown block in the form of the crown block track 5 is provided with a power supply part 7, and the power supply part 7 can generate electric energy required by crown block operation after obtaining the electromagnetic fields. The power supply part 7 is internally provided with an energy taking coil, and the electromagnetic field passes through the energy taking coil to generate electric energy and provide the generated electric energy for the crown block for the movement of the crown block. The crown block rail 5 is provided with a maintenance opening 8 because the crown block is damaged during use or because periodic maintenance and repair are required for long-term use. And when the crown block needs to be overhauled, the crown block moves to an overhauling section 9, and the overhauling section 9 can bear the crown block to leave the crown block track 5 and reach an overhauling point. But since the cable assembly needs to generate a magnetic field for power supply in the overhead travelling crane rail 5, the cable assembly needs to be continuous and uninterrupted to enable the passage of current through the closed loop. Also because the service section 9 at the service opening 8 is a movable section, the cable at this location cannot be set inside the service section 9 due to the limitation of the length and interference problems, and the cable assembly at this location may be exposed to the outside to become the external cable 3. The external cable 3 sags under the effect of gravity and the external cable 3 interferes with the movement of the service section 9 when the service section 9 carries the movement of the crown block, the winding of the external cable 3 taking place. The cable bearing mechanism 1 can bear the external cable 3 of the part, and when the overhaul section 9 needs to work, the cable bearing mechanism 1 bears the external cable 3 to avoid the overhaul section 9. When the service section 9 is finished working back to the service opening 8, the cable carrying mechanism 1 carries the external cable 3 back to the initial position. The overhead traveling crane track 5 equipment is convenient for overhauling the overhead traveling crane on the overhead traveling crane track 5, and meanwhile, the cost of the overhead traveling crane track 5 equipment is reduced because a new power control module 6 is not added.

Example 3

The embodiment of the invention provides an overhead travelling crane system. The crown block system includes: crown block track 5 equipment, power control module 6 and crown block. The crown block is arranged on the crown block track 5 of the crown block track 5 equipment and can slide along the crown block track 5. As shown in fig. 4 and 5, the crown block is provided with a power supply part 7 slidably arranged on the crown block track 5 and used for receiving the output current of the cable assembly and supplying power to the driving module of the crown block by the received current so that the crown block can be driven. The power supply member 7 is provided with a positioning groove 71, and the positioning groove 71 is embedded by the internal cable for positioning the internal cable.

As will be readily appreciated from the foregoing, the power control module 6 provides power to the cable assembly, which in turn is energized and generates an electromagnetic field. When the crown block normally runs on the crown block rail 5, the service section 9 is located at the original position, and the cable assembly generates an electromagnetic field surrounding the crown block rail 5. When the crown block runs on the fixed section of the crown block track 5, the cable assembly can pass through the positioning groove 71 along the setting direction of the crown block track 5, the limit of the internal cable can be realized through the positioning groove 71, and meanwhile, the cable assembly is prevented from interfering the crown block during the running process. When the crown block passes through the service section 9, the bearing part 11 bears the external cable 3 and is clamped into the positioning groove 71 to supply power for the crown block. The energy-taking induction coil in the power supply part 7 generates voltage through electromagnetic induction under the action of an electromagnetic field, and the electric energy for sliding is provided for the crown block through the voltage generated by the power supply part 7, so that wireless power supply for the crown block on the crown block track 5 is realized. When the crown block needs to be overhauled, the crown block needs to be lowered from the crown block track 5 through the overhauling section 9. The crane reaches the service section 9, the external cable 3 arranged on the bearing part 11 of the cable bearing mechanism 1 is clamped into the positioning groove 71 of the power supply part 7, and the crane can keep moving through the magnetic field generated by the external cable 3. When the cable bearing mechanism 1 works, the bearing part 11 drives the external cable 3 to be far away, and the crown block stays on the overhaul section 9. Meanwhile, due to the movement of the bearing part 11, the external cable 3 is far away from the overhaul section 9, so that the overhaul section 9 can be lifted normally, and lifting work of the overhaul section 9 is prevented from being influenced. When the overhauling section 9 brings the crown block which completes overhauling back to the maintenance opening 8 of the crown block track 5, the cable bearing mechanism 1 works and returns the bearing part 11 to the original position, so that the external cable 3 on the bearing part 11 can provide a magnetic field for the power supply part 7, the power supply part 7 can provide sliding electric energy for the crown block, and the crown block can normally run on the crown block track 5. The overhead travelling crane system is overhauled in time, the normal operation of the overhead travelling crane system is ensured, and the overhead travelling crane system only needs one set of power supply control module 6, so that the construction cost is reduced.

Further, the overhead travelling crane system can also be used for modifying the overhead travelling crane system formed as shown in fig. 6, so that the problem that the long overhaul section 9 of the track is insufficient is solved by adding the overhaul section 9 on the formed overhead travelling crane system. In the conventional overhead travelling crane system, an internal cable of a predetermined length is already laid in the overhead travelling crane rail 5. A maintenance opening 8 is formed in the crown block track 5, the track at the maintenance opening 8 is moved out, two sides of an internal cable at the maintenance opening 8 are disconnected and reconnected, and an external cable 3 at the maintenance opening 8 is prolonged. When the overhaul section 9 capable of lifting is added, the reconnected external cable 3 is arranged on the bearing part 11 of the cable bearing mechanism 1, the avoidance of the external cable 3 to the overhaul section 9 is realized through the cable bearing mechanism 1, and meanwhile, the wireless power supply to the crown block on the overhaul section 9 is realized.

Example 4

As shown in fig. 12, an embodiment of the present invention provides a control method of a cable bearing mechanism, the control method including:

S1, controlling a driving device 12 of the cable bearing mechanism 1, so that the driving device 12 drives a bearing part 11 bearing the external cable 3 to move along a moving direction perpendicular to the overhauling section 9 of the overhead travelling crane track 5. Wherein the external cable 3 is a cable exposed outside the service section 9 of the overhead travelling crane rail 5.

And S2, when the bearing part 11 moves along the movement direction perpendicular to the overhaul section 9 of the crown block track 5, and the external cable 3 is carried away from the overhaul section 9 by the bearing part 11, the driving device 12 is controlled to stop working. Or when the bearing part 11 moves along the movement direction perpendicular to the overhaul section 9 of the crown block track 5, the external cable 3 is brought to an initial position close to the overhaul section 9 by the bearing part 11, and the driving device 12 is controlled to stop working.

It is clear from the above that the cable carrying mechanism 1 needs to carry the external cable 3 for movement, so that the external cable 3 does not affect the movement of the service section 9, and the external cable 3 is prevented from winding the service section 9. Therefore, before the service section 9 needs to be moved, the cable bearing mechanism 1 first needs to move the external cable 3 along the movement direction of the vertical service section 9, so that the external cable 3 is avoided. Because the motion trail of the bearing part 11 and the overhauling section 9 are mutually perpendicular, and meanwhile, the departure point of the bearing part 11 and the overhauling section 9 is the only intersection point of the motion trail of the two, the intersection point of the bearing part 11 and the overhauling section 9 does not exist in the motion process, and interference cannot occur. The outer cable 3 is avoided for the overhaul section 9, and the danger in the overhaul process of the crown block is avoided.

While the foregoing is directed to embodiments of the present invention, other and further details of the invention may be had by the present invention, it should be understood that the foregoing description is merely illustrative of the present invention and that no limitations are intended to the scope of the invention, except insofar as modifications, equivalents, improvements or modifications are within the spirit and principles of the invention.
