Description
Technical Field
A hinge device for heavy load belongs to the technical field of mechanical connection, and particularly relates to a connection device for heavy mechanisms.
Background
Articulated joints and screw joints are used in a wide variety of applications, particularly in the mechanical sector. The bolt connection is fixed connection, and the two connection parts have no freedom degree and can not realize movement. The hinged connection allows rotational movement of the two parts connected about the hinge by releasing one or more rotational degrees of freedom. Therefore, the hinge device is widely used in places where rotational movement is required.
The stacker-reclaimer and the excavator are heavy machinery with extremely wide application range, the traditional method of the equipment is that a travelling mechanism is connected with a door seat frame through bolts, and the equipment is possibly deflected due to the influence of production, manufacturing, installation precision and equipment deformation in the use process, so that the travelling mechanism is easy to travel along the deflection direction, and the rail gnawing phenomenon occurs. If the gravity center is unstable, the tragedy of machine destruction and human death can also occur due to heavy machinery. And once the rail gnawing happens, the repair is not easy, the problem is likely to occur repeatedly, the damage to the equipment is large, and the working quality and the service life of the equipment are greatly influenced. Some parts of heavy equipment need to be connected with each other by releasing certain freedom, and if the connecting parts are fastened without freedom, the force applied to the parts cannot be well released when the parts are applied with external large force, so that the connecting parts are damaged. If the degree of freedom of release is too large in the use process of some equipment, the equipment can be in a dangerous state or the equipment can overturn and other dangers, and certain influences are caused on the safety and the service life of the equipment.
In the field of heavy machinery, a degree of freedom of rotation in one direction is generally required, such as a traveling trolley below a bucket wheel machine and an upper part, and since a rail is not absolutely horizontal, a degree of freedom of rotation in the rail direction is required. Chinese patent CN201621244338.2 provides a vertical hinge connection structure for a traveling mechanism and a door frame of a cantilever stacker-reclaimer, which increases the degree of freedom of a traveling trolley by changing the connection mode of the traveling mechanism and the door frame, so that wheels can freely rotate, and the occurrence of the phenomenon of rail gnawing is reduced. Chinese patent CN201220130114.4 provides a hinge structure and an excavator using the same, wherein the hinge structure includes a pin, a first end of the pin is fixedly connected to a first component, the pin passes through a hinge end of a second component in a relatively rotatable manner, and is applied to a four-bar linkage structure, and a limit component is fixed by a bolt parallel to an axis of the pin to bear a tensile stress parallel to the axis of the bolt and avoid bearing a shearing force.
Therefore, heavy hinge means structure commonly used is through free bearing and round pin hub connection, and the free bearing passes through round pin hub connection, and the round pin axle passes the part of connection completely, and the problem and the not enough of existence have: (1) the structure is heavy, and in order to bear larger weight, the sizes of the hinged support and the pin shaft are larger; (2) a part of the connection needs to be dug into a pin shaft hole, so that the bearing weight of related parts is weakened; (3) the structure is complicated, and the field installation is time-consuming and laborious. The solution of these problems is often directly related to the safety problems of heavy machinery, and also relates to the problems of reduced running performance and maintenance installation cost, reduced procedures and the like.
Disclosure of the invention
The invention provides a hinge device for heavy load, which aims to solve the technical problems of heavy structure, weakened bearing weight of related parts, time and labor waste in installation and the like of the conventional hinge device.
The technical scheme adopted by the invention is as follows:
a hinge device for heavy load is composed of a pin shaft, an upper semicircular block, a lower semicircular block, a circular cover plate and a rotational freedom limiting system, wherein the upper semicircular block is arranged above the pin shaft, the lower semicircular block is arranged below the pin shaft, and the inner side of the circular cover plate is simultaneously connected with one end of the upper semicircular block and one end of the lower semicircular block.
Circular apron and round pin axle between be connected through being no less than 3 groups of screws, connect the reinforcement through the steel wire between the screw.
The no less than 3 groups of screws are positioned at 1/3 of the radius of the center of the circular cover plate from the circumference, that is, the no less than 3 groups of screws are positioned on the circumference which takes the circular cover plate as the center of a circle and 1/3 of the radius of the circular cover plate as the radius.
The inner side end of the circular cover plate is of a structure that the circumferential edge of the circular cover plate protrudes inwards, and the outer side end of the circular cover plate is a circular plane.
The design of the inboard link of last semicircle piece and circular apron has little square gap, the inboard link design of lower semicircle piece and circular apron have the bayonet socket, ensure that the medial extremity of circular apron imbeds in little square gap and the bayonet socket.
The side face of the upper semicircular block is welded with at least one group of wedge blocks, the side face of the lower semicircular block is welded with at least one group of wedge pins, and the wedge blocks and the wedge pins are in clearance fit to limit the danger of equipment caused by overlarge rotation of the upper part. The wedge block is in a saddle shape with a downward opening and is positioned on the upper semicircular block; the wedge pin is bullet-shaped long cast iron and is positioned on the lower semicircular block. The wedge and the wedge pin are in clearance fit, and a small amount of rotational freedom of the upper part and the lower part is ensured. The heavy machinery needs a rotational freedom degree along the track direction because the track is not absolutely horizontal in the walking process, and the wedge block and the wedge pin are innovatively used for being in clearance fit, so that a proper amount of moving space is guaranteed between the walking trolley and the upper part, the walking trolley is not deflected, gnaws the track and is not blocked, and the mechanical balance is searched between a small-spacing space and a heavy machine body, so that the gravity center of the machinery is kept stable in walking, the installation, the processing and the replacement are simplified, and compared with the existing design, the heavy machinery has the advantages of being more reasonable in stress structure, more stable in connection structure, and longer in equipment working quality and service life.
The wedge block and the wedge pin are in clearance fit, another alternative scheme is that a wear-resistant rolling ball is adopted, the wear-resistant rolling ball can be made of steel, steel titanium alloy or steel zirconium alloy, at least one group of round concave surfaces which correspond to each other are dug in the upper semicircular block and the lower semicircular block, the wear-resistant rolling ball with the diameter slightly larger than that of the round concave surface is arranged in the middle of the upper semicircular block and the lower semicircular block, the upper semicircular block and the lower semicircular block are in clearance fit, and the degree of freedom of rotation of the upper part and the lower part which have vertical surfaces and horizontal surfaces is guaranteed. The wear-resistant rolling ball is arranged in a round concave position corresponding to the upper semicircular block and the lower semicircular block, the interior of the wear-resistant rolling ball is a hollow ball body, graphite slip powder is filled in the hollow ball body, and the graphite slip powder slowly flows into the round concave position of the lower semicircular block when moving along with a heavy-load machine through a downward thin pipeline to play a role in lubrication. The graphite lubricating powder adopted by the invention is not lubricated by grease, so that the grease is easy to leak due to weather or overheating of parts, and is mixed with dust, and the rotation is blocked.
The upper semicircular block is connected with the upper part through welding, the lower semicircular block is connected with the lower part through welding, the traditional methods of connecting through bolts and hinge shaft punching holes are changed, the upper semicircular block, the lower semicircular block and the lower part are integrated, the stress surface is greatly increased, the traditional stress structure is completely changed when the upper semicircular block, the upper part and the lower semicircular block are connected, and the bearing capacity is greatly improved and can reach more than 50 tons and more than hundreds of tons.
That is, the contact surface of the upper semicircular block and the lower semicircular block is equivalent to a hollow rectangle and is used as a bearing surface for bearing force. Because the innovation changes the point bearing of the stressed part into the surface bearing, the problem of the tensile stress of the running mechanism in the running process is considered, the problem of the shearing force of the heavy-load mechanism is solved scientifically, the machine is very stable, and safety accidents can not occur.
The hinge device for the heavy load is provided with a rotational freedom degree limiting system, and when the relative rotation angle of the upper semicircular block and the lower semicircular block exceeds a set value, the rotational freedom degree limiting system controls equipment to automatically stop.
Furthermore, a rotation angle detection device is arranged on the rotational freedom degree limiting system, when the relative rotation angle of the upper semicircular block and the lower semicircular block exceeds a set value, a signal is transmitted to the master control system, the master control system issues an instruction to each power unit, and each moving part of the whole equipment is stopped, so that the safety of the equipment is ensured.
A further scheme is that the rotation angle detection device can be arranged on the upper semicircular block, the rotation angle detection device is arranged on the lower semicircular block, when the relative rotation angles of the two detection devices exceed the set value of the system, a signal is transmitted to the master control system, the master control system issues an instruction to each power unit, and each moving part of the whole equipment is stopped.
Still another scheme is that the rotation angle detection device is provided with a limit switch in the wedge block, when the relative rotation angle of the upper semicircular block and the lower semicircular block exceeds a set value, the limit switch acts, signals are transmitted to the master control system, the master control system issues instructions to all power units, and all moving parts of the whole equipment are stopped.
Compared with the traditional hinge mode, the bearing weight of related parts is weakened due to the fact that pin shaft holes need to be dug in one part of connection, and a cutting process of the pin shaft holes does not exist between the upper semicircular block and the lower semicircular block and between the upper part and the lower part, so that the stress problem generated in the pin digging processing process is avoided, and the problems of weakness, crack and bearing force weakening caused by the fact that one end of the connecting part is dug in the traditional hinge structure can not be caused. Meanwhile, the traditional hinge mode is complex in structure and time-consuming and labor-consuming in field installation, the hinge structure is simple, the stress intensity is higher, various processing links are omitted, the resource cost is saved, and the labor consumption is reduced. In addition, the design of the rotational freedom degree limiting system and the rotational angle detection device realizes the automatic monitoring, detection and regulation of the road condition by the hinge device for heavy load, so that the heavy load mechanism is more intelligent.
