Description

Technical Field

[0001] This utility model relates to the field of aerial work robot technology, and in particular to an automatic retraction and deployment device for a fall protection safety rope of an aerial work robot. Background Technology

[0002] Aerial work robots, as important equipment to replace manual labor in dangerous high-altitude operations, have been widely used in fields such as power line inspection and building curtain wall maintenance. Safety ropes, as the key carriers for fall protection, directly determine the protective effect in conjunction with aerial work robots. Currently, safety ropes are used with one end connected to the top of the building and the other end fixed to the robot's own retraction device. For example, patent document CN206942177U discloses a fall protection device for aerial work robots. This device can move with the aerial work robot and can adjust the speed of the winch according to the distance between the aerial work robot and the sensor. In the event of a malfunction of the aerial work robot, the winch can be stopped in time to prevent fall accidents.

[0003] However, the current safety rope retraction device on top of the robot cannot lock the safety rope immediately when the robot falls, causing the robot to fall due to lack of stability. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model embodiment is to provide an automatic retraction and deployment device for the fall protection safety rope of a high-altitude work robot, which can solve the technical problem that the current retraction and deployment device of the safety rope set on the top of the work robot cannot lock the safety rope immediately when the robot falls.

[0005] This utility model embodiment proposes an automatic retraction and deployment device for a fall protection safety rope of a high-altitude work robot, including: a work robot and a retraction and deployment component disposed on the top of the work robot;

[0006] The take-up and take-down assembly includes a support frame, a take-up motor, and a winding roller. The support frame is fixedly mounted on the top of the working robot, and a rotating rod is rotatably inserted inside it. The winding roller is fixedly sleeved with the rotating rod, and a safety rope is fixedly wound around the rod wall. The take-up motor is fixedly mounted on the outer wall of the support frame, and its output shaft is fixedly connected to the rotating rod.

[0007] The top of the working robot also includes a support block, the top of the support block has a through hole, a guide rod is provided in the through hole, a guide roller is fixedly sleeved on the rod wall of the guide rod, an electric push rod is fixedly provided on the top of the support block, a clamping plate is fixedly provided at the end of the output shaft of the electric push rod, the safety rope is driven and engaged with the outer wall of the guide roller, and is also engaged with the clamping plate.

[0008] Optionally, the support block further includes a detection component, which includes a detection sensor and a detection magnetic ring fitted around the outside of the guide roller.

[0009] Optionally, the outer wall of the guide roller is provided with an annular groove, and the detection magnetic ring is fixedly disposed in the annular groove.

[0010] Optionally, a DC power supply box is fixedly provided on the top of the support block, and the DC power supply box is electrically connected to the electric push rod and the detection sensor.

[0011] Optionally, the clamping plate is arc-shaped, and a plurality of anti-detachment blocks are fixedly provided on the side of the clamping plate near the guide roller, the anti-detachment blocks being conical.

[0012] Optionally, an automatic retraction and deployment device for the fall protection safety rope of a high-altitude operation robot is proposed. The support block is fixedly provided with mounting plates on both sides of its bottom. The mounting plates are in contact with the top of the operation robot, and mounting holes are provided in the mounting plates.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0014] In this embodiment of the invention, the safety rope’s winding and unwinding speed can be detected when the safety rope comes into contact with the guide roller by the provided winding and unwinding components, support block, guide rod, guide roller, detection component, electric push rod, and clamping plate. When the detected speed exceeds a certain threshold, the detection component detects an abnormal signal and controls the electric push rod to start and drive the clamping plate to move. This causes the clamping plate to work with the anti-detachment block to squeeze the safety rope onto the outer wall of the guide roller. At this time, even if the winding and unwinding components are damaged, the robot can still be effectively positioned and protected from falling. Attached Figure Description

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0023] Reference manual attached Figure 1-3 The diagram shows a structural schematic of an automatic retraction and deployment device for a fall protection safety rope of a high-altitude work robot provided in an embodiment of the present invention.

[0024] The present invention provides a structure for an automatic retraction and deployment device for a fall protection safety rope of a high-altitude work robot, comprising: a work robot 1 and a retraction and deployment assembly disposed on the top of the work robot 1;

[0025] The take-up and take-down assembly includes a support frame 2, a take-up motor 3, and a winding roller 4. The support frame 2 is fixedly mounted on the top of the working robot 1, and a rotating rod 5 is rotatably mounted inside it. The winding roller 4 is fixedly sleeved with the rotating rod 5, and a safety rope 6 is fixedly wound around the rod wall. The take-up motor 3 is fixedly mounted on the outer wall of the support frame 2, and its output shaft is fixedly connected to the rotating rod 5.

[0026] The top of the work robot 1 also includes a support block 7. The top of the support block 7 has a through hole 8. A guide rod 9 is provided in the through hole 8. A guide roller 10 is fixedly sleeved on the rod wall of the guide rod 9. An electric push rod 11 is fixedly provided on the top of the support block 7. A clamping plate 12 is fixedly provided at the end of the output shaft of the electric push rod 11. The safety rope 6 is driven and cooperates with the outer wall of the guide roller 10 and is set in cooperation with the clamping plate 12. The clamping plate 12 is arc-shaped. A plurality of anti-detachment blocks 17 are fixedly arranged at intervals on the side of the clamping plate 12 near the guide roller 10. The anti-detachment blocks 17 are conical.

[0027] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: when the safety rope is in contact with the guide roller, the speed of the safety rope’s winding and unwinding can be detected. When the detected speed exceeds a certain threshold, the detection component detects an abnormal signal and controls the electric push rod to start and drive the clamping plate to move, so that the clamping plate, together with the anti-detachment block, squeezes the safety rope onto the outer wall of the guide roller. At this time, even if the winding and unwinding component is damaged, it can effectively position and prevent the robot from falling.

[0028] In this embodiment of the utility model, before using the work robot 1, one end of the safety rope 6 is fixed to the top of the building, and then the other end is fixedly wound around the winding roller 4 on the top of the robot. At this time, the winding roller 4 stably winds up and unwinds the safety rope 6 by rotating the winding motor 3. At this time, the safety rope 6 contacts the outer wall of the guide roller 10, and the winding speed of the safety rope 6 is detected by the detection component. When the speed is abnormal, the electric push rod 11 is activated, causing the clamping plate 12 to move, so that the clamping plate 12 drives the anti-detachment block 17 to squeeze the safety rope 6, lock the safety rope 6, and prevent the work robot 1 from falling.

[0029] In one possible implementation, the support block 7 further includes a detection component, which includes a detection sensor 13. The detection sensor 13 is fitted with a detection magnetic ring 14, which is sleeved on the outside of the guide roller 10. The outer wall of the guide roller 10 has an annular groove 15, and the detection magnetic ring 14 is fixedly installed in the annular groove 15. A DC power supply box 16 is fixedly installed on the top of the support block 7, and the DC power supply box 16 is electrically connected to the electric push rod 11 and the detection sensor 13.

[0030] In this embodiment of the utility model, the detection sensor 13 is a Hall sensor. When the safety rope 6 contacts the outer wall of the guide roller 10, the detection magnetic ring 14 is pushed and rotates in the annular groove 15. The detection magnetic ring 14 and the detection sensor 13 cooperate to detect the speed of the safety rope 6 in real time and accurately. When the speed is abnormal, the electric push rod 11 is started. The DC power supply box 16 provides stable power to the electric push rod and the sensor.

[0031] In one possible implementation, mounting plates 18 are fixedly provided on both sides of the bottom of the support block 7. The mounting plates 18 are in contact with the top of the working robot 1, and mounting holes are provided in the mounting plates 18.

[0032] In this embodiment of the utility model, the mounting plate 18 and the robot cooperate to fix the position of the support block 7, which makes it easy to separate the support block 7 from the working robot 1 without affecting the subsequent disassembly, assembly and modification of the working robot 1.
