A short-circuit grounding wire high-altitude operation hanging ring

Abstract

The present invention relates to the technical field of high-altitude operation hanging rings, and discloses a high-altitude operation hanging ring for a short-circuit grounding wire. The rotation of a clamping wheel drives the inner ring of a bearing to rotate, and the clamping wheel drives the entire bearing to rotate due to the restriction between the inner and outer rings of the bearing. The rotation of the outer ring of the bearing tightens the torsion spring. The horizontal component of the torsion spring tightening force on the middle surface of the inner ring of the hanging ring pulls the bearings on both sides toward the middle of the inner ring of the hanging ring. The bearing drives the clamping wheels on both sides to move toward the middle of the inner ring of the hanging ring, thereby driving the clamping wheels on both sides to increase the clamping force on the grounding wire. When the connecting wire between the human body and the hanging ring is extended to its maximum length, the operator can continue to work without returning to adjust the hanging ring position, effectively improving the efficiency of high-altitude operations, ensuring that the hanging ring is always stably electrically connected to the grounding wire when moving, and ensuring the stability of the short-circuit grounding wire hanging ring.

Description

Technical Field

[0001] The invention relates to the technical field of high-altitude operation hanging rings, in particular to a high-altitude operation hanging ring for a short-circuit grounding wire. Background Art

[0002] When performing construction work at height, a hanging ring is required. The two ends of the lifting rope are connected to the hanging ring and the high-altitude fixed object respectively, and then the protective rope is connected to the hanging ring to ensure the safety of the workers at height. At the same time, there is a high-altitude hanging ring hanging on the grounding wire. Through the intermediate potential operation method, a certain potential difference is maintained between the workers and the grounding body and the charged body. The workers can directly touch the equipment with the same potential as themselves, or indirectly touch the equipment with a higher potential than themselves through insulating tools to perform high-altitude work.

[0003] As shown in publication number CN114024153A, the operating unit is installed on one side of the clamping unit, and the position of the connecting rod is controlled by adjusting the position of the movable plate and the limit block cooperating with the movable plate, thereby determining the position of the adjusting assembly and the connecting assembly, and then the inner rod and the clamping frame are connected by the connecting ring. The operator holds the outer rod and uses the telescopic assembly to move the hanging ring to the high-voltage transmission line. When engaging with the high-voltage transmission line, the high-voltage transmission line presses the swing arm down. When the high-voltage transmission line enters the clamping frame, the elasticity of the spring is used to make the swing arm swing back to the initial position. The rotation of the swing arm facilitates the engagement between the clamping frame and the high-voltage transmission line, so that the hanging ring is hung on the high-voltage transmission line. The device is simple to use, convenient for live workers to quickly and effectively connect wires when installing the grounding hanging ring, and more convenient to disassemble, reducing the amount of high-altitude work and working time of live workers, and improving work safety.

[0004] However, there are still the following problems: when the workers at high altitude move away from the fixed point where the hanging ring is set to the ground wire during the operation, and when the connecting wire between the human body and the hanging ring is extended to the longest length, the workers return to adjust the position of the hanging ring, which makes the work more cumbersome and reduces the work efficiency of the high altitude operation. When the hanging ring moves with the workers, the hanging ring moves on the ground wire, causing the ground wire clamped by the hanging ring to loosen, resulting in the electrical connection between the hanging ring and the ground wire cannot be maintained at all times, posing a potential hazard to the safety of the workers. Summary of the Invention

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a short-circuit grounding wire high-altitude operation hanging ring, which has the following beneficial effects:

[0017] The outer ring of the bearing is tightened by the rotation of the clamping wheel, and the horizontal component of the tightening force of the torsion spring on the middle surface of the inner ring of the hanging ring pulls the bearings on both sides to move toward the middle of the inner ring of the hanging ring. The bearing drives the clamping wheels on both sides to move toward the middle of the inner ring of the hanging ring, so as to drive the clamping wheels on both sides to increase the clamping force on the ground wire, so as to avoid the loose connection with the ground wire when the hanging ring moves on the ground wire, resulting in electrical disconnection or unstable electrical connection. When the connecting wire between the human body and the hanging ring is extended to the longest length, the operator can continue to work without returning to adjust the position of the hanging ring, which effectively improves the efficiency of high-altitude operation and ensures that the hanging ring is always stably electrically connected to the ground wire when it moves, thereby ensuring the stability of the short-circuit ground wire hanging ring.

[0018] 2. For the high-altitude operation hanging ring of the short-circuit grounding wire, when the pressure on the telescopic rod becomes smaller or disappears, the limiting block is again opposite to the opening on the outer ring. At this time, the extension block is no longer completely restricted in the opening on the outer ring. The limiting block re-extends into the opening on the outer ring and is restricted by the torsion spring on the extension block. The limiting block pushes the limit card strip to re-lock into the limit buckle strip, so that the limit card strip and the limit buckle strip are re-wedged through the card slot and the buckle slot.

[0019] 3. The high-altitude operation hanging ring of the short-circuit grounding wire is slidably fitted on the through-hole on the extension block and the outer ring through the limit bar. When the extension block is extended, the limit bar connects the extension block and the bearing outer ring and limits it. When the extension block is retracted into the through-hole, the limit bar slides into the accommodating groove. The limit bar maintains the extension block always relative to the through-hole, ensuring a good fit between the extension block and the through-hole and ensuring the stable operation of the device.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] As introduced in the background technology, in order to solve the deficiencies in the existing technology, the present application proposes a high-altitude operation hanging ring for a short-circuit grounding wire.

[0033] In a typical embodiment of the present application, Figure 1 As shown, a hanging ring for high-altitude operation of a short-circuit grounding wire includes a hanging ring 1. Clamping wheels 25 are rotatably engaged on both sides of the inner ring of the hanging ring 1. Bearings 33 are provided on the top of the clamping wheels 25 on both sides. The clamping wheels 25 are connected to the bearings 33. A torsion spring 48 is provided on the outer ring of the bearing 33. One end of the torsion spring 48 is connected to the outer ring of the bearing 33, and the other end of the torsion spring 48 is fixed to the middle of the inner ring of the hanging ring 1. When the hanging ring 1 moves on the grounding wire, the clamping wheel 25 drives the bearing 33 to rotate, and the inner and outer rings of the bearing 33 are restricted to drive the torsion spring 48 to contract.

[0034] When using the present invention:

[0035] The hanging ring 1 is put on the ground wire from the lower end of the hanging ring 1, and the clamping wheel 25 clamps the ground wire between the clamping wheels 25. When the high-altitude operator moves away from the position where the hanging ring 1 is put on the ground wire during the operation, and when the connecting wire between the operator and the hanging ring 1 is extended to the longest length, as the operator continues to move to drive the hanging ring 1 to move on the ground wire, the clamping wheel 25 rotates on the ground wire due to the clamping force. The rotation of the clamping wheel 25 drives the inner ring of the bearing 33 to rotate, and is restricted by the inner ring and outer ring of the bearing 33 so that the clamping wheel 25 drives the entire bearing 33 to rotate. The rotation of the outer ring of the bearing 33 tightens the torsion spring 48, and the tightening force of the torsion spring 48 is applied to the inner ring of the hanging ring 1. The horizontal component of force on the middle surface pulls the bearings 33 on both sides to move toward the middle of the inner ring of the hanging ring 1, and the bearings 33 drive the clamping wheels 25 on both sides to move toward the middle of the inner ring of the hanging ring 1, so as to increase the clamping force on the ground wire by tightening the torsion spring 48, thereby preventing the hanging ring 1 from becoming loose from the ground wire when moving on the ground wire, thereby causing electrical disconnection or unstable electrical connection, so that the operator can continue to work without returning to adjust the position of the hanging ring when the connecting wire between the human body and the hanging ring is extended to the longest length, effectively improving the efficiency of high-altitude operations, and ensuring that the hanging ring is always stably electrically connected to the ground wire when moving, thereby ensuring the stability of the short-circuit ground wire hanging ring.

[0036] Further, such as Figure 2-3 As shown, fixing parts 21 are fixedly installed on both sides of the upper and lower ends of the inner ring of the hanging ring 1. The distance between the fixing parts 21 on both sides of the lower end is greater than the cross-sectional length of the ground wire. Slide grooves 22 are provided on both sides of the fixing part 21. Slide plates 23 are slidably fitted in the slide grooves 22. The slide plates 23 on both sides are rotatably fitted with shaft rods 24, and clamping wheels 25 are fixedly installed on the shaft rods 24.

[0037] Among them, the slide 23 on the fixing part 21 can move in the slide groove 22, so that the slide 23 drives the shaft 24 to move, and the movement of the shaft 24 drives the clamping wheel 25 to move, so that the clamping wheel 25 can move toward the middle of the hanging ring 1, so that the clamping wheel 25 can change the clamping force on the ground wire sleeved in the inner ring of the hanging ring 1, ensuring that the clamping force of the clamping wheel 25 on the ground wire increases when the hanging ring 1 moves on the ground wire, thereby ensuring the stability of the electrical connection between the hanging ring 1 and the ground wire.

[0038] Furthermore, the clamping wheel 25 is provided with a wheel pattern 251 , which increases the friction force of the clamping wheel 25 when it moves on the ground line similar to a “wheel pattern”, thereby preventing the clamping wheel 25 from slipping on the ground line.

[0039] Preferably, the wheel pattern 251 is configured as a straight vertical pattern, or the wheel pattern 251 is configured as an "S"-shaped vertical pattern, which is perpendicular to the direction of the ground line to enhance the friction force of the clamping wheel 25 on the ground line.

[0040] Further, such as Figure 3-4 As shown, connecting frames 31 are fixedly installed on the slides 23 at the top of both sides, and connecting rods 32 are rotatably fitted on the connecting frames 31. One end of the connecting rod 32 is fixedly connected to the shaft 24. The axis of the connecting rod 32 coincides with the axis of the shaft 24. The bearing 33 is arranged on the side of the connecting rod 32, and the connecting rod 32 passes through the inner ring of the bearing 33.

[0041] The connecting frame 31 is fixed to the slide 23 so that the slide 23 can move in the slide groove 22 along with the connecting frame 31 , and the connecting rod 32 is driven to move through the shaft 24 , so that the connecting rod 32 drives the bearing 33 to move along with the shaft 24 .

[0042] Further, such as Figure 5-6 As shown, a fixing groove 34 is provided on the inner ring of the bearing 33 , and a positioning rod 35 is fixedly installed on the connecting rod 32 . One end of the positioning rod 35 extends into the fixing groove 34 , and one end of the positioning rod 35 is fixedly installed inside the fixing groove 34 .

[0043] Preferably, a protrusion is provided on one end of the positioning rod 35, and the protrusion is made of elastic rubber. A groove is provided in the fixing groove 34. After one end of the positioning rod 35 is extended into the fixing groove 34, the positioning rod 35 is snapped into the fixing groove 34 through the adaptation of the protrusion and the groove, so as to facilitate the disassembly and assembly of the positioning rod 35 and the bearing 33, thereby improving the convenience of disassembly and assembly during maintenance of the hanging ring.

[0044] The inner ring of the bearing 33 is fixedly connected to the connecting rod 32 via a positioning rod 35 so that the inner ring of the bearing 33 is driven to rotate when the connecting rod 32 rotates.

[0045] Further, such as Figure 6-7As shown, a telescopic rod 41 is fixedly mounted on the connecting rod 32, and a through hole 42 is opened on the inner ring and the outer ring of the bearing 33. The through hole 42 on the inner ring is opposite to the through hole 42 on the outer ring. The extending rod of the telescopic rod 41 passes through the through hole 42 on the inner ring, and the extending rod of the telescopic rod 41 passes through the through hole 42 on the outer ring. A limiting block 43 is fixedly mounted on one end of the extending rod of the telescopic rod 41. The size of the limiting block 43 is smaller than the size of the through hole 42. A spring 44 is sleeved on the extending rod of the telescopic rod 41. One end of the spring 44 is connected to the fixed rod of the telescopic rod 41, and the other end of the spring 44 is connected to the limiting block 43.

[0046] Furthermore, the fixed rod length of the telescopic rod 41 is smaller than the inner ring radius of the bearing 33, thereby ensuring that the spring 44 has a good contraction space when being compressed.

[0047] When the telescopic rod 41 is compressed and retracted, the limiting block 43 compresses the extension rod of the telescopic rod 41 and retracts the spring 44, thereby retracting the limiting block 43 between the outer ring and the inner ring of the bearing 33. This disengages the limiting block 43 and the extension rod of the telescopic rod 41 from the opening 42 on the outer ring, so that the telescopic rod 41 no longer restricts the outer ring of the bearing 33. When the connecting rod 32 drives the telescopic rod 41 to rotate, the telescopic rod 41 no longer drives the outer ring of the bearing 33 to rotate.

[0048] When the pressure on the telescopic rod 41 decreases or disappears, the elastic restoring force of the spring 44 causes the extension of the telescopic rod 41 to first extend the limiting block 43 between the outer ring and the inner ring of the bearing 33, so that the limiting block 43 adheres to the inner ring of the outer ring of the bearing 33. As the connecting rod 32 drives the telescopic rod 41 to rotate, the limiting block 43 is again aligned with the through hole 42 on the outer ring, so that the extension of the telescopic rod 41 and the limiting block 43 are re-extended into the through hole 42 on the outer ring, so that the outer ring of the bearing 33 can be driven to rotate again.

[0049] Further, such as Figure 8-9 As shown, the upper and lower ends of one side of the limiting block 43 are fixedly installed with a limit card strip 45, and a card slot 451 is provided on the limit card strip 45, the opening of the card slot 451 on the upper limit card strip 45 is at the top, and the opening of the card slot 451 on the lower limit card strip 45 is at the bottom. A limit buckle strip 46 is relatively arranged on the limit card strip 45, and a buckle slot 461 is provided on the limit buckle strip 46, the opening of the buckle slot 461 at the upper end is at the bottom, and the opening of the buckle slot 461 at the lower end is at the top, so that the limit card strip 45 and the limit buckle strip 46 are wedged with each other through the card slot 451 and the buckle slot 461.

[0050] Furthermore, the limiting clip 45 is made of elastic plastic, that is, it has the ability to recover after slight deformation.

[0051] Further, such as Figure 5-6As shown, an extension block 47 is fixedly mounted on the limiting buckle strip 46 . The size of the extension block 47 is the same as that of the through opening 42 on the outer ring. The extension block 47 is opposite to the torsion spring 48 .

[0052] Among them, when the clamping wheel 25 rotates, the clamping wheel 25 drives the bearing 33 to rotate, and the bearing 33 drives the torsion spring 48 to tighten. As the torsion spring 48 continues to tighten until it is attached to the outer ring of the outer ring of the bearing 33, the torsion spring 48 presses the extension block 47 to move, and the extension block 47 presses the limit block 43 to move, so that the extension block 47 is completely retracted into the through-hole 42 on the outer ring. As the extension block 47 fills the through-hole 42 on the outer ring and continues to rotate between the inner ring and the outer ring of the bearing 33, the limit strip 45 is rotated at this time, so that the limit strip 45 passes through the wedging between the card slot 451 and the buckle slot 461 and slides out of the limit buckle strip 46. , so that the limiting block 43 disengages from the extending block 47, that is, the restriction between the inner ring and the outer ring of the bearing 33 disappears, so that the outer ring of the bearing 33 no longer rotates with the inner ring; and when the pressure on the telescopic rod 41 becomes smaller or disappears, the limiting block 43 is again opposite to the through-hole 42 on the outer ring. At this time, the extension block 47 is no longer completely restricted in the through-hole 42 on the outer ring. The limiting block 43 re-extends into the through-hole 42 on the outer ring and is restricted by the torsion spring 48 on the extending block 47. The limiting block 43 pushes the limiting card strip 45 to re-engage it in the limiting buckle strip 46, so that the limiting card strip 45 and the limiting buckle strip 46 are re-wedged through the card groove 451 and the buckle groove 461.

[0053] Further, such as Figure 5-7 As shown, a receiving groove 51 is provided on the extension block 47, and the end of the receiving groove 51 close to the connecting rod 32 is an open opening. A limiting strip 52 is slidably fitted in the receiving groove 51, and a limiting protrusion is provided on one end of the limiting strip 52. A first limiting rail 53 is provided in the receiving groove 51, and the limiting protrusion on the limiting strip 52 is slidably fitted in the first limiting rail 53. A second limiting rail 54 is provided in the through opening 52 on the outer ring, and a limiting protrusion is provided on the other end of the limiting strip 52, and the limiting protrusion on the limiting strip 52 is slidably fitted in the second limiting rail 54.

[0054] Among them, the limiting bar 52 slides and fits on the extension block 47 and the through-opening 42 on the outer ring. When the extension block 47 is extended, the limiting bar 52 connects the extension block 47 with the outer ring of the bearing 33 and limits it. When the extension block 47 is retracted into the through-opening 42, the limiting bar 52 slides and is retracted into the accommodating groove 51. Through the action of the limiting bar 52, the extension block 47 is always maintained opposite to the through-opening 42, ensuring a good fit between the extension block 47 and the through-opening 42 and ensuring the stable operation of the device.

[0055] Further, such as Figure 1 、 Figure 10As shown, a connecting protrusion 61 is fixedly installed on the hanging ring 1, a fixing button 62 is bolted on the connecting protrusion 61, a connecting line 63 is clamped and fixed between the connecting protrusion 61 and the fixing button 62, and the connecting line 63 is connected to the human body. An insulating rod 64 is fixedly installed on the bottom end of one side of the hanging ring 1, and a handle 65 is provided at the lower end of the insulating rod 64. Both the insulating rod 64 and the handle 65 are made of insulating material.

[0056] Working principle:

[0057] When in use, the hanging ring 1 is put on the ground wire from the lower end of the hanging ring 1, and the clamping wheel 25 clamps the ground wire between the clamping wheels 25. When the high-altitude worker moves away from the position where the hanging ring 1 is put on the ground wire as he works, and when the connecting wire between the worker and the hanging ring 1 extends to the longest length, as the worker continues to move to drive the hanging ring 1 to move on the ground wire, the clamping wheel 25 rotates on the ground wire due to the clamping force, and the rotation of the clamping wheel 25 drives the inner ring of the bearing 33 to rotate, and is restricted by the inner ring and outer ring of the bearing 33 so that the clamping wheel 25 drives the entire bearing 33 to rotate, and the rotation of the outer ring of the bearing 33 tightens the torsion spring 48, and the tightening force of the torsion spring 48 on the hanging ring 1 The horizontal component of force on the middle surface of the inner ring pulls the bearings 33 on both sides to move toward the middle of the inner ring of the hanging ring 1, and the bearings 33 drive the clamping wheels 25 on both sides to move toward the middle of the inner ring of the hanging ring 1, so as to increase the clamping force on the ground wire by tightening the torsion spring 48, thereby preventing the hanging ring 1 from becoming loose from the ground wire when moving on the ground wire, thereby preventing the electrical disconnection or unstable electrical connection. When the connecting wire between the human body and the hanging ring is extended to the maximum length, the operator does not need to return to adjust the hanging ring position to continue working, effectively improving the efficiency of high-altitude work, and ensuring that the hanging ring is always stably electrically connected to the ground wire when moving, thereby ensuring the stability of the short-circuit ground wire hanging ring;

[0058] After the operator moves the connecting wire 63 to its maximum length, the tension drives the hanging ring 1 to move on the ground wire, causing the clamping wheel 25 to rotate and the connecting rod 32 to rotate. Restricted by the positioning rod 35 and the telescopic rod 41 passing through the bearing 33, the connecting rod 32 drives the bearing 33 to rotate, causing the bearing 33 to drive the torsion spring 48 to contract. When the torsion spring 48 is tightened, the tension of one end of the torsion spring 48 fixed to the fixing member 21 on the fixing member 21 tightens the clamping degree of the clamping wheels 25 on the ground wire, thereby preventing the hanging ring 1 from loosening the clamping force with the ground wire when moving on the ground wire, resulting in unstable electrical connection or disconnection.

[0059] When the clamping wheel 25 rotates, the clamping wheel 25 drives the bearing 33 to rotate, and the bearing 33 drives the torsion spring 48 to tighten. As the torsion spring 48 continues to tighten until it is attached to the outer ring of the outer ring of the bearing 33, the torsion spring 48 presses the extension block 47 to move, and the extension block 47 presses the limit block 43 to move, so that the extension block 47 is completely retracted into the through hole 42 on the outer ring. As the extension block 47 fills the through hole 42 on the outer ring and continues to rotate between the inner ring and the outer ring of the bearing 33, the limit clip 45 is rotated, so that the limit clip 45 slides out of the limit clip 46 through the wedging between the card groove 451 and the buckle groove 461, so that the limit block 43 is separated from the extension block 47, that is, the restriction between the inner ring and the outer ring of the bearing 33 disappears, so that the outer ring of the bearing 33 no longer rotates with the inner ring;

[0060] After the torsion spring 48 is fully tightened onto the outer ring of the bearing 33, the torsion spring 48 presses the telescopic rod 41 to contract, so that the extension block 47 is retracted into the through-hole 42 on the outer ring of the bearing 33. As the connecting rod 32 continues to rotate, the limiting block 43 detaches from the extension block 47, so that the outer ring of the bearing 33 no longer continues to rotate, and the telescopic rod 41 and the limiting block 43 continue to rotate with the inner ring of the bearing 33. When the hanging ring 1 stops moving, the torsion spring 48 ensures that the hanging ring 1 is stably electrically connected to the ground wire; and when the pressure on the telescopic rod 41 becomes smaller or disappears, the limiting block 43 is again opposite to the through-hole 42 on the outer ring. At this time, the extension block 47 is no longer completely confined in the through-hole 42 on the outer ring, and the limiting block 43 The control block 43 re-extends into the through-hole 42 on the outer ring and is restricted by the torsion spring 48 on the extension block 47. The limiting block 43 pushes the limiting card strip 45 to re-lock into the limiting buckle strip 46, so that the limiting card strip 45 and the limiting buckle strip 46 are re-wedged through the card slot 451 and the buckle slot 461. The telescopic rod 41 passes through the outer ring of the bearing 33 again to drive the bearing 33 to rotate, so that the operator can continue to work without returning to adjust the position of the hanging ring 1 when the connecting line 63 between the human body and the hanging ring is extended to the longest length, which effectively improves the efficiency of high-altitude operations and ensures that the hanging ring 1 is always stably electrically connected to the ground wire when moving, thereby ensuring the stability of the short-circuit ground wire hanging ring.
