Description

Technical Field

[0004] However, the above technical solution has the following shortcomings:

[0005] By turning the handle, the servo motor and drive motor are controlled to rotate, reeling in one end of the rope while releasing it from the other end, allowing the elevator to rise and fall on the rope.

DETAILED DESCRIPTION

[0050] Example 1

[0051] like Figures 1-11 As shown, the lifting robot capable of emergency stop proposed in this embodiment includes a housing 1, a rolling plate assembly, a guide assembly, an emergency stop mechanism and a limit mechanism.

[0052] like Figure 2 As shown, a drive device is provided within the housing 1. The drive device includes a motor 4 and a reducer 5. The output end of the motor 4 is connected to the input end of the reducer 5, and the output end of the reducer 5 is connected to the rolling disk assembly, thereby driving the rolling disk assembly forward and reverse, thereby achieving the movement of the entire lifting robot on the rope. The housing 1 is provided with a speed control knob 2 for adjusting the speed of the output end of the drive device and a holding brake 3 for braking. The speed control knob 2 is similar to the knob on an electric bicycle, i.e., a Hall effect knob. The speed of the output end of the motor 4 is adjusted by rotating the speed control knob 2. The speed control knob 2 can be provided with an anti-slip sleeve or anti-slip groove. The brake operation can be performed by using a switch on the holding brake 3. The holding brake 3 uses an existing brake that can achieve a braking function.

[0053] like Figure 2 and Figure 3As shown, the rolling disk assembly has a rope winding channel, and the rolling disk assembly is connected to the output end of the driving device. The rolling disk assembly includes two symmetrically distributed rotating disks 6. The rope winding channel is located between the two rotating disks 6. The rotating disk 6 has a protruding rib portion on the side facing the rope winding channel. A plurality of rib portions are evenly arranged around the central axis of the rotating disk 6. The rib portion can clamp the rope to increase friction, and can move on the rope when the rotating disk 6 rotates, which can ensure the accuracy and smoothness of the movement.

[0054] like Figure 2 As shown, the guide assembly includes a guide wheel 24 and a guide frame 25. The guide wheel 24 is rotatably set on the guide frame 25. The outer peripheral surface of the guide wheel 24 is provided with a concave wheel groove along the axial direction from both ends to the middle direction. The wheel groove can further stably clamp the top fixed rope 37 for guidance. The guide frame 25 is set on the casing 1. The guide frame 25 has a guide groove 251. The guide groove 251 plays a limiting role to prevent the top fixed rope 37 from lateral deviation and prevent the rope from falling off the guide wheel 24.

[0055] like Figure 4-Figure 8 As shown, the emergency stop mechanism includes a fixed seat 7, an abutment frame 12, a pressure handle 13, a fixed sleeve 14, a torsion spring 15, a sliding rod 16, a sliding frame 17 and an elastic member b18. A mounting groove b702 is provided on the fixed seat 7, the fixed seat 7 is provided on the housing 1, the abutment frame 12 is rotatably provided on the fixed seat 7, the fixed sleeve 14 is provided on the fixed seat 7 and presses the abutment frame 12 against the fixed seat 7, and a plurality of limiting grooves 121 are distributed circumferentially at one end of the abutment frame 12 away from the fixed sleeve 14, and the abutment frame 12 has an abutment end 123 protruding outward, and the abutment end 123 can stably abut against the top fixed rope 37 to achieve the emergency stop purpose of the entire robot. A torsion spring 15 is mounted on the outer periphery of the fixed sleeve 14, with its ends connected to the fixed sleeve 14 and the abutment frame 12, respectively. The pressure handle 13, sliding rod 16, and sliding frame 17 are sequentially connected. The sliding rod 16 extends through the fixed seat 7. The sliding frame 17 has a limiting rod portion 171 that can be inserted into the limiting groove 121. The sliding frame 17 is slidably mounted in the mounting groove b702. The ends of the elastic member b18 are connected to the sliding frame 17 and the housing 1, respectively. The elastic member b18 can be a spring. After pressing the pressure handle 13 once, the abutment frame 12 presses against the rope, and the limiting rod portion 171 is locked in the limiting groove 121 in the other direction to limit the position, ensuring the abutment frame 12 is tightened, and the lifting robot stops suddenly. If the abutment frame 12 needs to be released from its tight grip on the rope, the pressing handle 13 can be pressed again, rotating the abutment frame 12 in the opposite direction to release the rope. The pressing handle 13 can then be released, allowing the elastic force of the elastic member b18 to re-engage the limiting rod 171 in the limiting groove 121. At this point, the torsion spring 15 stores elastic potential energy for the next emergency stop, allowing the lifting robot to continue lifting on the top fixed rope 37.

[0056] like Figure 4 and Figure 5 As shown, the limiting mechanism is arranged on the fixed seat 7 and forms a rope threading space between the fixed seat 7. The top fixed rope 37 can pass through the rope threading space. When the robot is lifted or lowered, the rotating disk assembly can move stably and securely on the rope.

[0057] This embodiment conveniently presses the pressure handle 13 to tighten the top fixed rope 37, preventing relative slippage. This achieves an emergency stop, enabling precise stopping at a desired location or emergency stopping before encountering an obstacle, ensuring personnel safety and providing high reliability in emergency stop control. During use, the top fixed rope 37 is directly threaded through the guide groove 251, the rope winding channel, and the rope threading space. The guide wheel 24 guides the top fixed rope 37 within the guide groove 251. The driving device drives the rolling disc assembly to rotate, and the movement of the rolling disc assembly on the top fixed rope 37 is used to achieve lifting and lowering. When an emergency stop is required, just press the pressure handle 13. The pressure handle 13 drives the sliding frame 17 to move inward through the sliding rod 16. The sliding frame 17 squeezes the elastic part b18, and the limiting rod 171 moves away from the limiting groove 121 to release the limit. At this time, due to the torsion force of the torsion spring 15, the torsion spring 15 will drive the abutment frame 12 to rotate toward the top fixed rope 37 at the guide wheel 24, and press the top fixed rope 37 against the guide wheel 24 to achieve locking, which can immediately stop the entire lifting robot from moving forward. The emergency stop operation is simple and fast.

[0058] Example 2

[0059] like Figure 4-11 As shown, this embodiment proposes a lifting robot capable of emergency stop. Compared to the first embodiment, in this embodiment, the abutment frame 12 has a circular sleeve surface 124. The abutment frame 12 is distributed with ratchet teeth 122 around the central axis of rotation. A rotating frame 19 is rotatably provided on the sleeve surface 124. The rotating frame 19 is located between the ratchet teeth 122 and the fixed seat 7. The rotating frame 19 can rotate stably without misalignment or shaking. The rotating frame 19 is provided with a push handle 20 and a stopper 22. The push handle 20 can be used to drive the rotating frame 19 to rotate, thereby improving the convenience of operation. The stopper 22 can be a bolt or other part that can be connected to the rotating frame 19. A pawl 21 is rotatably provided on the rotating frame 19. An elastic member c23 is connected between the pawl 21 and the stopper 22. The elastic member c23 can be a spring, which can rebound the pawl 21, so that the pawl 21 can be bounced off by the ratchet 122 when rotating counterclockwise, and can be stuck in the ratchet 122 when rotating clockwise and drive the abutment frame 12 to rotate clockwise. By reciprocating the push handle 20, the abutment frame 12 can be intermittently driven to rotate clockwise, so as to turn the abutment frame 12 away and release the tightness on the rope.

[0060] like Figure 9As shown, the pawl 21 has a blocking rod portion 211. The rotating frame 19 is connected to a cover plate 192, which can shield the inner pawl 21 and the elastic member c23 to ensure the neatness of the structure and prevent debris from entering the inner side to affect the smooth rotation of the pawl 21. Figure 11 As shown, a limiting channel 191 is provided on the rotating frame 19 for the movement of the blocking rod 211. The limiting channel 191 is used to limit the range of movement of the blocking rod 211 to ensure that the pawl 21 can smoothly push the abutment frame 12 to rotate clockwise and reset, and can effectively prevent the pawl 21 from shaking at will.

[0061] Example 3

[0062] like Figure 4-Figure 6 As shown, this embodiment proposes a lifting robot that can stop suddenly. Compared with the first embodiment, in this embodiment, the limiting mechanism includes a limiting frame 8, a pushing member 9, a slide 10 and an elastic member a11. The limiting frame 8 is rotatably set on the fixed seat 7. The limiting frame 8 is provided with a mounting groove a801 and a strip hole 802. The mounting groove a801 is connected to the strip hole 802. The two ends of the elastic member a11 are respectively connected to the bottom of the mounting groove a801 and the slide 10. The elastic member a11 can adopt a compression spring. The pushing member 9 passes through the strip hole 802 and is connected to the slide 10; the bottom end of the fixed seat 7 is provided with a card slot 701 for the slide 10 to be clamped.

[0063] In this embodiment, when inserting the top fixed rope 37, it is not necessary to insert the rope from the free end, but the rope can be inserted from any part of the rope. In specific operation, the pusher 9 is pulled inward, and the pusher 9 drives the slide 10 to slide inward. The slide 10 compresses the elastic member a11, and the slide 10 moves away from the slot 701, and the limit frame 8 is turned away. At this time, the rope can be directly passed through the gap between the limit frame 8 and the fixed seat 7 and moved to the area between the limit frame 8 and the fixed seat 7. Then, the rope can be put between the two rotating disks 6, and the rope can be clamped into the guide groove 251 and pressed against the guide wheel 24. After the rope is placed, press the pusher 9, rotate the limit frame 8 in the opposite direction, and then release the pusher 9. The elastic member a11 releases its elastic potential energy and pushes the slide 10 to move. The end of the slide 10 is clamped into the slot 701 for limiting, effectively preventing the rope from loosening.

[0064] Example 4

[0065] like Figure 12 and Figure 13As shown, the present embodiment proposes a lifting robot capable of emergency stop. Compared with the first embodiment, in the present embodiment, two groups of rope limiting assemblies are arranged side by side on the housing 1, and the two groups of rope limiting assemblies are respectively located on both sides of the rolling disk assembly. The rope limiting assembly includes a slide rail 26, a slide 27, a rotating rod 28, a screw 29, a retaining ring 30, an elastic member d31 and a limiting buckle 32. A connecting groove for installing the slide rail 26 is provided on the housing 1, the slide 27 is slidably arranged on the slide rail 26 and is located inside the connecting groove, the rotating rod 28 is rotatably arranged on the slide 27, and a rope threading channel is formed between the rotating rod 28 and the slide 27, so that the slide 27 can stably It slides to adjust the position of the slide 27 according to the weight of people or items, and reduces the wear on the rope while ensuring that the rope is effectively limited through the rope threading channel. The rotating rod 28 has a protruding connecting rod portion 281, and the connecting rod portion 281 is connected to a screw 29. A retaining ring 30 is connected between the connecting rod portion 281 and the screw 29. A limiting buckle 32 is slidingly provided on the connecting rod portion 281, and an elastic part d31 is connected between the limiting buckle 32 and the retaining ring 30. The elastic part d31 can be a compression spring. The slide 27 is provided with a groove 271 for the connecting rod portion 281 to be engaged and a retaining groove 272 for the limiting buckle 32 to be engaged.

[0066] In this embodiment, two sets of rope limit assemblies can be used in conjunction with the rolling disk assembly to pass through the fixed rope 38 at both ends, allowing the lifting robot to be used to transfer people or objects on ropes with fixed ends. When setting up the robot, the limit buckle 32 is first moved away from the retaining groove 272 to form a gap between the slide 27 and the rotating rod 28. The rope is then inserted and then inserted between the two rotating disks 6. The limit buckle 32 is then pulled outward, and the rotating rod 28 is rotated until the connecting rod portion 281 is engaged in the groove 271. At this point, the limit buckle 32 is released, and the elastic member d31 pushes the limit buckle 32 to move, locking the limit buckle 32 in the retaining groove 272, effectively preventing the rope from loosening. When people or objects are moved using the robot, due to their own gravity, the rope is eventually distributed in a "V" shape in the robot area.

[0067] Example 5

[0068] This embodiment proposes a lifting robot capable of emergency stop. Compared with the fourth embodiment, in this embodiment, a bracket 33 is provided on the housing 1, a connecting belt 34 is connected to the bottom of the bracket 33, and a lock 35 is connected to the bottom of the connecting belt 34. Figure 14As shown, the lock 35 includes a lock handle 351, a lock rod 352, and a stop sleeve 353. The lock handle 351 has an upper connecting end and a lower connecting end. One end of the lock rod 352 is rotatably connected to the upper connecting end of the lock handle 351, and the other end of the lock rod 352 is engaged at the lower connecting end of the lock handle 351. The stop sleeve 353 is slidably mounted on the lock rod 352. A rotating cover 36 is rotatably mounted on the bracket 33 to cover the outer side of the rolling disk assembly. After the rope is threaded through, the rotating cover 36 is rotated to block and limit the inner rolling disk assembly, further preventing the rope from loosening. The rotating cover 36 can be connected to the bracket 33 with a rotational damping mechanism, or it can be designed to snap onto the outer periphery of the rolling disk assembly.

[0069] In this embodiment, when a person or an object is hung on the robot, the connection is made through the lock buckle 35. The person or the object can wear a hanging buckle or a belt, and then the hanging buckle or the belt is passed through the inner side of the lock handle 351, and the lock rod 352 is closed. Finally, the limit sleeve 353 is dragged downward and then rotated to a certain angle to limit the closed position of the lock handle 351 and the lock rod 352, thereby ensuring that the person or the object can be stably and safely hung on the lock buckle 35.

[0070] Example 6

[0071] This embodiment proposes a lifting robot capable of emergency stop. Compared with the fifth embodiment, the use method of this embodiment includes a method for lifting personnel and a method for transferring personnel.
