Description

Technical Field

[0001] This invention relates to the field of live-line working technology, and in particular to a collaborative storage device and robot for holding a vibration damper for clamping cables. Background Technology

[0002] High-voltage transmission lines located at high altitudes are susceptible to environmental influences, leading to vibrations and galloping. Overhead lines are repeatedly bent at suspension points, causing material fatigue and eventually resulting in accidents such as strand breakage and line breakage. Vibration dampers, attached to the suspension points of line towers, can absorb or reduce vibration energy, change the line's swaying frequency, and prevent line vibration or galloping. They are used to eliminate line self-vibration and resonance caused by wind. Existing vibration dampers typically consist of a clamping mechanism, a connecting block, two steel strands fixedly installed at both ends of the connecting block, and two hammer bodies fixedly installed at the ends of the two steel strands. The clamping mechanism is fixedly connected to the connecting block to secure the device to the high-voltage transmission line.

[0003] When maintaining or repairing high-voltage transmission lines, manual operation poses certain safety hazards. Therefore, robots are sometimes used to carry out the work. During the operation, robots need to use anti-vibration hammers. However, it is inconvenient for robots to hold and store anti-vibration hammers, which usually takes a long time and affects the efficiency of maintaining and repairing high-voltage transmission lines. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: the clamping and storage of anti-vibration hammers by robots is inconvenient and usually takes a long time, which affects the work efficiency of high-voltage transmission line maintenance. Therefore, this invention proposes a collaborative storage device and robot for clamping and storing anti-vibration hammers for cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A collaborative storage device for clamping a cable vibration damper includes a base. The upper surface of the base has a horizontally open mounting opening. A threaded rod with opposite thread directions on the left and right sides is horizontally rotatably installed in the mounting opening. A slider is threaded onto both sides of the threaded rod. An mounting plate is fixedly installed on the upper surface of the slider. A placement groove is opened on the upper surface of the mounting plate. Two first spring rods are fixedly installed on the groove wall. A sliding plate is fixedly installed at the top of the two first spring rods. Two mounting rods are fixedly installed on the sides of the two sliding plates that are close to each other.

[0007] On the side of each of the two mounting plates that are close to each other, an L-shaped connecting plate is fixedly mounted by two second spring rods, and a limit roller is fixedly mounted on one end of the connecting plate.

[0008] As a preferred embodiment, each of the two mounting rods has a spherical groove at one end that is close to the other, and a sphere is rolled and embedded in the spherical groove.

[0009] As a preferred embodiment, the two ends of the threaded rod protrude through the left and right side walls of the base, respectively, and each end is fixedly fitted with an adjusting wheel.

[0010] As a preferred embodiment, a limiting plate is fixedly mounted on the surface of the mounting rod, and an anti-slip layer is adhered to the surface of the limiting plate. The anti-slip layer is made of rubber.

[0011] As a preferred embodiment, the upper surface of the base is symmetrically provided with stabilizing components. The stabilizing components include two fixed plates fixedly installed on the upper surface of the base, two first inclined plates respectively fixedly installed on the top of the two fixed plates, and three stabilizing plates. The upper surface of the base and the surfaces of the two first inclined plates are fixedly connected to the three stabilizing plates respectively through third spring rods. The side of the stabilizing plate away from the third spring rods is provided with multiple grooves. The three third spring rods are stretched together by a pressing component.

[0012] As a preferred embodiment, the pressing assembly includes a movable ring, three pressing rods fixedly mounted circumferentially on the surface of the movable ring, and three second inclined plates. A support plate is fixedly sleeved on the third spring rod. The multiple second inclined plates are respectively fixedly connected to one end of the multiple support plates. The end faces of the multiple pressing rods are respectively arranged facing the inclined surfaces of the multiple second inclined plates. The upper surface of the base is symmetrically provided with sliding openings. A sliding rod is horizontally installed in the sliding opening. A sliding seat is slidably sleeved on the sliding rod. The top ends of the two sliding seats are respectively fixedly connected to the outer ring walls of the two movable rings. A telescopic spring is sleeved on the sliding rod. The two ends of the telescopic spring are respectively fixedly connected to the surface of the sliding seat and the opening wall of the sliding opening.

[0013] A robot for clamping a cable anti-vibration hammer includes a storage device for clamping and storing the anti-vibration hammer, the storage device being a collaborative storage device for clamping a cable anti-vibration hammer as described in any of the above.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The clamping, fixing, and releasing of the vibration damper can be quickly completed through the cooperation of the threaded rod, multiple mounting rods, and limit rollers. It is convenient and fast, and can clamp and fix vibration dampers of any size. The clamping and fixing object is no longer a vibration damper of a certain size, which improves the efficiency of clamping and fixing vibration dampers and also improves practicality.

[0016] After the vibration damper is clamped and fixed by multiple mounting rods, the two limiting rollers will also limit the position of the vibration damper, ensuring that the vibration damper will not move vertically or horizontally, thus improving the clamping and fixing effect of the vibration damper.

[0017] When the steel strand in the vibration damper swings with the high-voltage transmission line, the stabilizing components and the pressure-blocking components work together. When the swing amplitude of the steel strand is large, multiple stabilizing plates will press against the end surface of the steel strand near the connecting block. This prevents the connection between the steel strand and the connecting block from being subjected to large forces due to the large swing amplitude, thus avoiding loosening and improving the stability of the vibration damper when it is performing vibration damping work.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-10 A collaborative storage device for a cable clamping anti-vibration hammer includes a base 1. The upper surface of the base 1 has a horizontally opened mounting opening 25. A threaded rod 2 with opposite thread directions on the left and right sides is horizontally rotatably installed in the mounting opening 25. A slider 3 is threadedly sleeved on both sides of the threaded rod 2. A mounting plate 4 is fixedly installed on the upper surface of the slider 3. A placement groove is opened on the upper surface of the mounting plate 4. Two first spring rods 5 are fixedly installed on the groove wall. A sliding plate 6 is fixedly installed at the top of the two first spring rods 5. Two mounting rods 7 are fixedly installed on the side of the two sliding plates 6 that are close to each other. The two ends of the threaded rod 2 pass through the left and right side walls of the base 1 respectively, and each is fixedly sleeved with an adjusting wheel 10.

[0031] On the side of the two mounting plates 4 that are close to each other, an L-shaped connecting plate 8 is fixedly installed by two second spring rods 26. A limit roller 9 is fixedly installed at one end of the connecting plate 8. The horizontal height of the limit roller 9 is higher than the horizontal height of the mounting rod 7.

[0032] When it is necessary to clamp and fix the anti-vibration hammer, first push the connecting block between the multiple mounting rods 7. At this time, the two limiting rollers 9 will first slide into contact with the surface of the connecting block. Then, under the action of pressure, the two second spring rods 26 will retract until the connecting block contacts the base 1. At this time, the two second spring rods 26 will quickly stretch, so that the two limiting rollers 9 will quickly approach each other. The horizontal height of the two limiting rollers 9 is higher than the central axis of the connecting block.

[0033] Then, by rotating the threaded rod 2, the sliders 3 on both sides of the threaded rod 2 will move horizontally relative to each other under the constraint of the mounting opening 25, controlling the two sliders 3 to move closer to each other. At this time, the two mounting plates 4 will bring the two mounting rods 7 closer to each other. The ends of the multiple mounting rods 7 that are close to each other will slide in contact with the surface of the steel strand. Since the horizontal height of the mounting rods 7 is higher than the central axis of the steel strand, as the multiple mounting rods 7 gradually approach each other, under the pressure of the arc surface of the steel strand, the two sliding plates 6 will move upward first, that is, the multiple first spring rods 5 will stretch first, and then the multiple first spring rods 5 will bring the two plates 6 to move upward first. The slide plate 6 quickly moves down and resets. As the two mounting plates 4 approach each other, the two limiting rollers 9 abut against the surface of the connecting block. As the two mounting plates 4 approach each other, the multiple second spring rods 26 gradually retract. As the second spring rods 26 retract, the total length of the second spring rods 26 gradually shortens, and the space for retraction and extension gradually decreases until they move to the point where the ends of the multiple mounting rods 7 abut against each other. At this point, the anti-vibration hammer is clamped between the multiple mounting rods 7 and the base 1. Due to the limitation of the two limiting rollers 9, the anti-vibration hammer cannot move vertically or horizontally, which improves the effect of clamping and fixing the anti-vibration hammer.

[0034] When it is necessary to release the clamp, simply rotate the adjusting wheel 10 to control the rotation of the threaded rod 2, so that the two sliders 3 move away from each other, thereby separating the multiple mounting rods 7. The second spring rod 26 is gradually stretched to the reset position. At this time, the total length of the second spring rod 26 has increased, and the retractable space has increased. Then, the anti-vibration hammer can be moved upward to remove it. During the removal process, the two second spring rods 26 will retract due to the pressure force of the arc surface of the connecting block.

[0035] If it is necessary to clamp and fix other larger-sized vibration dampers, since the horizontal height of the mounting rod 7 may be lower than the central axis of the connecting block in the vibration damper, it is not possible for the slide plate 6 to move upward by the pressure force between the mounting rod 7 and the arc surface of the connecting block. In this case, it is necessary to manually control the two slide plates 6 to move upward, so that the multiple first spring rods 5 are stretched. Then, by rotating the threaded rod 2, the ends of the multiple mounting rods 7 that are close to each other are pressed together, so that the vibration damper is clamped between the lower surface of the multiple mounting rods 7 and the upper surface of the base 1. The object clamped and fixed is no longer a vibration damper of a certain size, which improves practicality.

[0036] Both mounting rods 7 have spherical grooves at their close ends, and spherical balls 27 are rolled and embedded in the grooves. The spherical balls 27 can change the sliding friction between the mounting rods 7 and the connecting block in the vibration damper into rolling friction, thereby reducing the friction between the mounting rods 7 and the connecting block and avoiding jamming.

[0037] A limiting plate 11 is fixedly installed on the surface of the mounting rod 7. The surface of the limiting plate 11 is bonded with an anti-slip layer made of rubber. As multiple mounting rods 7 gradually approach each other, multiple limiting plates 11 will also gradually approach the two connecting plates 8. After the anti-vibration hammer is clamped and fixed, multiple limiting plates 11 will abut against the two connecting plates 8 respectively, thereby improving the effect of limiting the retraction of multiple second spring rods 26.

[0038] A stabilizing assembly is symmetrically arranged on the upper surface of the base 1. The stabilizing assembly includes two fixed plates 12 fixedly installed on the upper surface of the base 1, two first inclined plates 13 respectively fixedly installed on the top of the two fixed plates 12, and three stabilizing plates 14. The upper surface of the base 1 and the surfaces of the two first inclined plates 13 are fixedly connected to the three stabilizing plates 14 respectively by third spring rods 15. The side of the stabilizing plate 14 away from the third spring rods 15 has multiple grooves 16. The three third spring rods 15 are stretched together by a pressing assembly. The pressing assembly includes a moving ring 17 and three pressing rods 18 circumferentially fixedly installed on the surface of the moving ring 17. The base 1 has three second inclined plates 19, and a support plate 20 is fixedly sleeved on the third spring rod 15. The multiple second inclined plates 19 are fixedly connected to one end of the multiple support plates 20 respectively. The end faces of the multiple pressing rods 18 are respectively arranged facing the inclined surfaces of the multiple second inclined plates 19. The upper surface of the base 1 is symmetrically provided with sliding openings 21. A sliding rod 22 is horizontally installed in the sliding opening 21. A sliding seat 23 is slidably sleeved on the sliding rod 22. The top ends of the two sliding seats 23 are respectively fixedly connected to the outer ring walls of the two moving rings 17. A telescopic spring 24 is sleeved on the sliding rod 22. The two ends of the telescopic spring 24 are respectively fixedly connected to the surface of the sliding seat 23 and the opening wall of the sliding opening 21.

[0039] When installing the vibration damper, the two steel strands in the damper need to be passed through the two moving rings 17 respectively. Initially, the distance between the two sliding blocks 23 is at its maximum. When the steel strands in the damper swing with the high-voltage transmission line, if the swing amplitude is small, the force at the connection point between the steel strands and the connecting block is also small, and the steel strands will not contact the inner ring of the moving ring 17, thus the moving ring 17 will not move. If the swing amplitude is large, the force at the connection point between the steel strands and the connecting block is large, and the surface of the steel strands will abut against the inner ring wall of the moving ring 17 during the swing. The 17 under the pressure will only move towards the connecting block. During the movement, multiple pressure rods 18 will move together with the moving ring 17, and their end faces will slide into contact with the inclined surfaces of multiple second inclined plates 19 respectively. Under the pressure of the inclined surfaces, multiple third spring rods 15 will stretch together, so that multiple stabilizing plates 14 will move closer to each other and tightly abut against the end surface of the steel strand near the connecting block. This can reduce the swing amplitude at the connection between the steel strand and the connecting block, thereby reducing the swing force at the connection, avoiding loosening due to large forces at the connection, and improving the stability of the anti-vibration hammer when performing anti-vibration work.

[0040] When the swing amplitude decreases, the surface of the steel strand no longer contacts the inner wall of the moving ring 17. As a result, the moving ring 17 will quickly return to its original position under the elastic potential energy of the extension spring 14, and the multiple stabilizing plates 14 will also leave the surface of the steel strand. Since the steel strand is composed of multiple strands of steel wire twisted together, its surface is uneven and not smooth. Therefore, when the stabilizing plate 14 comes into contact with the surface of the steel strand, some of the steel wires on the surface of the steel strand will enter the multiple grooves 16 opened on the surface of the stabilizing plate 14, thereby enhancing the stabilizing effect of the steel strand.

[0041] A robot for clamping a cable damper includes a storage device for clamping and storing the damper.

[0042] In this invention, when it is necessary to clamp and fix the anti-vibration hammer, the connecting block is first aligned between the multiple mounting rods 7 and pushed in. At this time, the two limiting rollers 9 will first slide into contact with the surface of the connecting block. Then, under the action of pressure, the two second spring rods 26 will retract until the connecting block contacts the base 1. At this time, the two second spring rods 26 will quickly stretch, so that the two limiting rollers 9 will quickly move closer. Then, by rotating the threaded rod 2, the sliders 3 threadedly connected to the left and right sides of the threaded rod 2 are controlled to move closer to each other. At this time, the two mounting plates 4 will... The two mounting rods 7 will move closer to each other until they touch. At this point, the anti-vibration hammer will be clamped between the mounting rods 7 and the base 1. Due to the limitation of the two limiting rollers 9, the anti-vibration hammer cannot move vertically or horizontally, which improves the clamping and fixing effect of the anti-vibration hammer. The clamping and fixing of the anti-vibration hammer can be quickly completed by the cooperation between the threaded rod 2, the multiple mounting rods 7 and the limiting rollers 9. It is convenient and quick, and improves the work efficiency of inspecting and maintaining high-voltage transmission lines.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
