Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1, the embodiment of the application provides a simplified composition structure of an aerial construction operation device, which may be any one of an outer wall spraying robot, an outer wall surface cleaning robot, an aerial fire-fighting robot, and the like, and can respectively replace manpower or assist people in completing works such as aerial outer wall spraying, outer wall cleaning, and the like, so as to achieve the effects of improving quality, increasing efficiency, and reducing cost.

Exemplarily, an exterior wall painting robot is taken as an example, which includes: high altitude hanging basket 200, construction executing mechanism, pulling mechanism 100 and feeding component 300. The high-altitude hanging basket 200 is connected with a lifting driving mechanism and can move up and down in a vertical plane under the driving force provided by the lifting driving mechanism so as to finish the requirement of spraying the outer wall surfaces of buildings with different heights. For example, the lifting driving mechanism adopts a rope winding motor, a driving shaft of the rope winding motor is connected with the high-altitude hanging basket 200 through a steel cable, when the driving shaft winds the steel cable, the high-altitude hanging basket 200 moves upwards, and when the driving shaft winds and unwinds the steel cable, the high-altitude hanging basket 200 moves downwards.

The construction executing mechanism is arranged on the high-altitude hanging basket 200. For example, the construction executing mechanism in this embodiment is a spraying mechanism, which can realize automatic and uniform spraying of the paint on the outer wall surface of the building. Alternatively, in other embodiments, the construction executing mechanism can also be a spraying mechanism, a soot blowing mechanism and the like.

The traction mechanism 100 is arranged on the high-altitude hanging basket 200; the supply member 300 is installed in the drawing mechanism 100 and connected to the construction actuator. The feeding component 300 can be a material conveying pipe, a gas conveying pipe, a cable and the like, and is used for realizing the functions of supplying power, conveying materials and conveying gas for the construction execution mechanism and ensuring the reliable work of the construction execution mechanism.

Generally, the feeding member 300 is extended upward from the ground and is mounted on the high-altitude basket 200 by the pulling mechanism 100. When the overhead basket 200 travels a high distance from the ground, the feed assembly 300 suspended in the air is longer in length and heavier. When the high-altitude hanging basket 200 is lifted in an accelerating or decelerating manner, a large inertia force is generated by the suspended portion of the feeding component 300, and the feeding component 300 is installed at one side of the high-altitude hanging basket 200, so that the high-altitude hanging basket 200 is subjected to an asymmetric force to shake, which affects the spraying quality and has a certain potential safety hazard.

In view of the above, the traction mechanism 100 having vibration isolation and energy dissipation capabilities is provided to prevent the above problems and ensure safe and high quality construction work of the equipment.

Or, as an alternative, the outer wall painting robot may not be provided with the high altitude hanging basket 200, but only include the construction executing mechanism, the feeding component 300 and the drawing mechanism 100, the drawing mechanism 100 is provided on the construction executing mechanism, and the feeding component 300 is installed on the drawing mechanism 100 and connected with the construction executing mechanism. At this time, the inertia force generated by the feeding component 300 can be directly blocked and eliminated by the traction mechanism 100 arranged on the construction execution mechanism, so that the stable pose of the construction execution mechanism is ensured, and the operation quality and the safety are ensured.

As shown in fig. 2 to 6, a pulling mechanism 100 is shown for an embodiment of the present application, the pulling mechanism 100 including: a mounting plate 10, said mounting plate 10 being adapted to be connected to a high-altitude gondola 200. For example, in the present embodiment, the mounting plate 10 has a mounting through hole, and after the mounting through hole is aligned with the threaded hole on the high-altitude hanging basket 200, the mounting through hole is screwed and locked by a bolt, so that the mounting manner is simple, the connection strength is high, and the mounting and dismounting are convenient. Of course, in other embodiments, the mounting plate 10 and the overhead basket 200 may be any one of snap connection, welding, riveting, and the like.

The pulling mechanism 100 further includes a yaw mechanism 20, a sliding tube 30, and an elastic vibration isolation mechanism 40. The deflection mechanism 20 is movably arranged on the mounting plate 10; the sliding tube 30 is slidably disposed on the deflection mechanism 20, and the sliding tube 30 is used for connecting with the feeding component 300; the elastic vibration damping mechanism 40 is provided on the yaw mechanism 20 and connected to the slide pipe 30, and the elastic vibration damping mechanism 40 is configured to have a capability of canceling the inertial force generated by the feeding member 300 by elastic expansion and contraction deformation.

In summary, the technical solution of the present embodiment has the following advantages: the traction mechanism 100 of the scheme is applied to equipment in high-altitude construction operation equipment, and is specifically used for assembling and connecting the feeding component 300 with a high-altitude cable, and meanwhile, the influence of the inertia force generated when the feeding component 300 moves up and down on the instability of the high-altitude hanging basket 200 can be eliminated. Specifically, the pulling mechanism 100 can be firmly and reliably mounted on the overhead hanging basket 200 through the mounting plate 10, when the overhead cable is lifted and decelerated, the feeding component 300 can generate a large inertia force due to its own weight, and the inertia force can be smoothly transmitted to the elastic vibration isolation mechanism 40 through the deflection mechanism 20, at this time, the elastic vibration isolation mechanism 40 can elastically expand and contract and deform to eliminate the received inertia force, and simultaneously, the sliding pipe 30 is driven to lift and slide relative to the mounting plate 10, so that the inertia force can be effectively isolated and consumed, the inertia force is prevented from being transmitted to the overhead hanging basket 200, the gravity center of the overhead hanging basket 200 is unstable and shakes, the quality of overhead work is ensured, and safety accidents caused by the overhead hanging basket 200 colliding with the wall surface of a building are prevented.

Since the drawing mechanism 100 is vertically installed at the outer side of the high-altitude gondola 200, it is possible to define the up-down sliding direction of the sliding pipe 30 as the Z-axis direction. Which serves to support the elastic vibration isolating mechanism 40 and follow the elastic vibration isolating mechanism 40.

The pulling mechanism 100 further includes a pipe joint 90a provided at a lower end of the sliding pipe 30 and adapted to be detachably assembled with the feeding member 300. The pipe joint 90a is used to assemble the feeding means 300 with the sliding pipe 30. For example, the pipe joint 90a is a quick-assembly quick-disassembly joint, which can reduce the difficulty of assembling and disassembling the feeding component 300 and improve the operation efficiency.

With continued reference to fig. 2 and 3, in some embodiments, the resilient vibration isolation mechanism 40 includes: an elastic expansion device 41 having elastic expansion and contraction deformability; and a fixing plate 42, a first end of the elastic expansion piece 41 is disposed on the deflection mechanism 20, a second end of the elastic expansion piece 41 is connected to the fixing plate 42, and the fixing plate 42 is disposed on the sliding tube 30.

When the high-altitude hanging basket 200 runs at an abrupt acceleration and deceleration, the inertia force generated by the feeding component 300 is transmitted to the mounting plate 10 through the sliding pipe 30, then transmitted to the deflection mechanism 20, and finally transmitted to the elastic expansion piece 41 through the deflection mechanism 20, and at the moment, the elastic expansion piece 41 generates expansion deformation to eliminate the inertia force, so that the effect of preventing the inertia force from being further transmitted to the high-altitude hanging basket 200 is achieved, and the stable posture of the high-altitude hanging basket 200 is ensured. The fixing plate 42 is used for connecting the elastic expansion piece 41 and the sliding tube 30 into a whole, so that the structural strength and stability are ensured, and the sliding tube 30 can synchronously expand, contract and slide along with the elastic expansion piece 41.

Alternatively, the elastic bellows 41 is provided as a gas spring. Because the reaction force of the gas spring is constant, the inertial force exerted on the high-altitude basket 200 by the feeding component 300 (such as a feeding pipe, a gas pipe, a cable and the like) can be well absorbed. Of course, the elastic expansion/contraction device 41 in other embodiments may be another buffer mechanism capable of achieving the same technical effect as the gas spring.

With reference to fig. 2 and fig. 3, the elastic vibration isolation mechanism 40 further includes a first universal joint 43 and a second universal joint 44, the first universal joint 43 is connected between the first end of the elastic expansion device 41 and the yawing mechanism 20, and the second universal joint 44 is connected between the second end of the elastic expansion device 41 and the fixing plate 42. The first universal joint 43 and the second universal joint 44 provide the elastic expansion piece 41 with the ability of swinging in any direction in space, and ensure the smooth expansion and contraction deformation of the elastic expansion piece 41.

For example, referring to fig. 7, in some embodiments, each of the first universal joint 43 and the second universal joint 44 includes a rotating base 45 and a rotating body 46, the rotating base 45 defines a spherical groove 451, the rotating body 46 defines a spherical body 461, the spherical body 461 is rotatably disposed in the spherical groove 451, and a diameter of the spherical body 461 is larger than a diameter of a notch of the spherical groove 451. In operation, ball 461 may rotate in any direction within ball slot 451, thereby providing a desired degree of rotational freedom in the direction of elastic expansion device 41. Further, since the diameter of the ball 461 is larger than the diameter of the opening of the ball groove 451, when the elastic expansion and contraction device 41 is stretched for a long time, the ball 461 will not be pulled out of the ball groove 451 even if it is pulled by the elastic expansion and contraction device 41, thereby ensuring the structural stability and safety.

Preferably, in this scheme, the elastic expansion piece 41, the first universal joint 43 and the second universal joint 44 are all provided with two sets, and the elastic expansion piece 41, the first universal joint 43 and the second universal joint 44 are assembled and matched one by one and symmetrically distributed on two opposite sides of the sliding pipe 30, so that energy dissipation paths are increased, and a better vibration isolation and energy dissipation effect can be achieved. Further, the first gimbal 43 and the second gimbal 44 provide the elastic vibration isolating mechanism 40 with rotation in the Z-axis direction, and can eliminate the rattling of the two elastic expanders 41 caused by incomplete fitting.

In addition, in any of the above embodiments, the yaw mechanism 20 includes a first bushing 21, a yaw block 22, and a first yaw shaft 23, the sliding tube 30 is slidably inserted into the first bushing 21, the first bushing 21 is provided with a first sliding hole, a first end of the first yaw shaft 23 is provided on the yaw block 22, and a second end of the first yaw shaft 23 is rotatably provided in the first sliding hole, so that the yaw mechanism 20 can swing around a first direction. When the feeding member 300 generates the inertia force in the first direction, the first bushing 21 is reciprocated about the axis of the first yaw axis 23 relative to the yaw block 22 via the first yaw axis 23, so as to transmit the inertia force in the first direction to the elastic vibration isolating mechanism 40, thereby eliminating the influence of the inertia force in the first direction on the stability of the high altitude nacelle 200.

For example, the first direction in the present embodiment may specifically refer to the X-axis direction.

With reference to fig. 2 and fig. 6, further, the yawing mechanism 20 further includes a second bushing 24 and a second yawing axle 25, the yawing block 22 is provided with a second sliding hole, a first end of the second yawing axle 25 is disposed on the mounting plate 10, and a second end of the second yawing axle 25 is rotatably disposed in the second sliding hole through the second bushing 24, so that the yawing mechanism 20 can swing around a second direction. When the feeding member 300 generates the inertia force in the second direction, the swing block 22 is swung back and forth with respect to the mounting plate 10 about the axis of the second swing shaft 25 by the second swing shaft 25, so that the inertia force in the second direction can be transmitted to the elastic vibration isolating mechanism 40 to eliminate the influence of the inertia force in the second direction on the stability of the high-altitude nacelle 200.

For example, the second direction in the present embodiment may specifically refer to the Y-axis direction.

In addition, on the basis of any of the above embodiments, the mounting plate 10 is provided with an accommodating gap 11, the deflection block 22 is inserted into the accommodating gap 11, and the outer side wall of the deflection block 22 is in spaced fit with the inner side wall of the accommodating gap 11. The accommodating notch 11 is arranged to provide a space required by the swing of the swing block 22; secondly, the mounting plate 10 and the deflection block 22 can be arranged more compactly, the overall volume of the traction mechanism 100 is reduced, and the requirement on the working space is reduced. In this embodiment, the accommodating notch 11 is a U-shaped notch formed along the negative direction of the Y axis, and the forming process is simple.

In summary, the provision of the yaw mechanism 20 is effective to be able to swing together with the feeding member 300 to adjust the direction of the inertial force of the feeding member 300, thereby ensuring that the inertial force is smoothly transmitted to the elastic vibration isolating mechanism 40.

With continued reference to fig. 3 and 4, in some embodiments, the pulling mechanism 100 further includes a deflection block 22, a first limit position sensor 60, and a first sensing block 70, the fixing frame 50 is disposed on the mounting plate 10, the first limit position sensor 60 is disposed at an upper end of the fixing frame 50, and the first sensing block 70 is disposed at an upper end of the sliding tube 30 and can be triggered and matched with the first limit position sensor 60. In the process of lifting the high-altitude hanging basket 200, when the feeding component 300 (such as an air pipe, a cable and the like) is hung by a projection on the outer wall surface of a building, the actual tensile force applied to the elastic expansion piece 41 exceeds the rated tensile force, at the moment, the first induction block 70 descends along with the sliding pipe 30 to trigger the first extreme position sensor 60, at the moment, the first extreme position sensor 60 feeds back a fault signal, the high-altitude hanging basket 200 stops climbing, and equipment installation is guaranteed.

Further, the pulling mechanism 100 further includes a second limit position sensor 80 and a second sensing block 90, the second limit position sensor 80 is disposed at the lower end of the fixed frame 50, and the second sensing block 90 is disposed at the middle portion of the sliding tube 30 and can be in trigger fit with the second limit position sensor 80. When the high-altitude hanging basket 200 descends, if the feeding component 300 (such as an air pipe, a cable and the like) falls off or cannot descend smoothly due to the obstruction of a projection on the non-exterior wall surface of a building, the compression amount of the elastic expansion piece 41 is reduced, the sliding pipe 30 is pushed to move upwards along the Z direction, the second induction block 90 triggers the second limit position sensor 80 and feeds back a fault signal, the hanging basket stops descending, and the installation of equipment is ensured.

In normal operation, if the gravity of the feeding component 300 (such as an air pipe, a cable, etc.) is smaller than the rated load of the constant tension spring, the first sensing block 70 and the second sensing block 90 will not trigger the corresponding first limit position sensor 60 and the corresponding second limit position sensor 80. With the continuous extension of the feeding component 300 (such as an air pipe, a cable and the like), the pulling force exerted on the constant tension spring is gradually increased, the reaction force exerted on the high-altitude hanging basket 200 is also gradually increased, and if the reaction force of the constant tension spring is a fixed value F, the gravity of the feeding component 300 (such as an air pipe, a cable and the like) is G, the inertia force generated when the high-altitude hanging basket 200 is accelerated and decelerated is T, and G + T is less than or equal to F, the constant tension spring can slowly absorb the inertia force generated by the feeding component 300 (such as an air pipe, a cable and the like) in the acceleration and deceleration process of the high-altitude hanging basket 200 and slowly transmit the inertia force to the high-altitude hanging basket 200, so that the high-altitude hanging basket 200 is prevented from shaking due to the sudden pulling force.
