Description

Technical Field

[0001] This invention relates to the field of high-voltage connector maintenance equipment technology, and in particular to a high-voltage equipment anti-fall maintenance bracket. Background Technology

[0002] When using high-voltage cables for long-distance power supply, due to insufficient cable length or other reasons, it is often necessary to install high-voltage connectors in the middle for relay to complete the power supply task. In order to ensure the safety and reliability of the power supply line, routine maintenance and inspection of the high-voltage connectors are required every once in a while. Each time an inspection is carried out, the cables at both ends of the high-voltage connector must be removed, the high-voltage connector must be placed on the base plate for inspection, which is a cumbersome, labor-intensive, time-consuming and labor-intensive process. As a type of high-voltage connector, the cable joint is an indispensable component in the cable line. It is used to connect two cable segments and improve the electric field at the ends of the two cables. Long circuits must connect two or more cable segments, which requires a straight connector. A straight connector is an accessory that connects two cables to form a continuous circuit. Specifically, it refers to a joint where the metal shell of the connector is electrically continuous with the metal shield and insulation shield of the connected cable. In order to reduce the induced electromotive force of the metal sheath, high-voltage lines need insulating joints to achieve cross-transfer connection to eliminate the circulating current generated by the induced electromotive force.

[0003] When using high-voltage connectors, whether cable joints or other types, regular maintenance is required. Currently, ladders or folding supports are used for maintenance personnel to climb up. However, existing maintenance supports cannot be adjusted to a suitable height to allow personnel to inspect equipment at different heights. Furthermore, the limited range of the testing platform on the current supports restricts their use. Since the height of each worker varies, the guardrails are not easily adjustable; guardrails that are too high hinder maintenance work, while those that are too low pose a safety hazard. Therefore, designing a fall-prevention maintenance support for high-voltage equipment is essential. Summary of the Invention

[0004] The main objective of this invention is to provide a high-voltage equipment anti-fall maintenance bracket, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-voltage equipment anti-fall maintenance support includes a base.

[0015] By adopting the above technical solution, the nut can be clamped with a tool and rotated, which can drive the upright to rotate, thereby driving the worm gear to rotate.

[0016] The invention is further configured such that: a worm gear is rotatably connected to the inner wall of the mounting groove, the worm gear is meshed with a worm wheel, and an auxiliary platform is fixedly connected to the outer surface of the worm gear.

[0017] By adopting the above technical solution, the rotation of the worm gear can drive the worm to rotate, thereby driving the auxiliary platform to make adjustments.

[0018] The present invention is further configured such that a ladder is fixedly connected to the outer surface of the base.

[0019] By adopting the above technical solution and installing escalators, staff can easily climb the ladders, and the equipment can then be inspected and maintained using the testing platform.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, by using a servo motor, a rotating shaft, a first rack, a second rack, and gears, when it is necessary to repair equipment at different heights, the worker stands on the repair platform and starts the servo motor, which drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the gear to rotate, thereby driving the first rack and the second rack to slide downwards or upwards respectively. This allows the first rack to push the moving frame, and the second rack to push the repair platform for adjustment, making it convenient for workers to repair equipment at different heights.

When the worm rotates, it can drive the auxiliary platform to adjust. When adjusted to a suitable distance, the usable area of ​​the maintenance platform can be increased, making it convenient for workers to use. When it is not necessary to increase the usable area of ​​the maintenance platform, the rotation and adjustment of the maintenance platform can adjust the maintenance platform to a vertical position, or the maintenance platform can be used as a guardrail to achieve the purpose of protection.

[0022] 3. In this invention, by using a sleeve, knob, threaded push rod, railing, and telescopic rod, when the railing needs to be adjusted, the knob is held and rotated. When the knob rotates, it drives the threaded push rod to rotate, thereby allowing the threaded push rod to be adjusted out of the sleeve. The adjustment of the threaded push rod can push the push block to adjust, thus pushing the railing to adjust its height, making it convenient for workers of different heights to use. When the threaded push rod is adjusted, the telescopic rod can also push the railing to adjust. Attached Figure Description

In this embodiment, a servo motor 5 is fixedly connected to the outer surface of the base 1, a rotating shaft 6 is fixedly connected to the output end of the servo motor 5, a gear 7 is fixedly connected to the outer surface of the rotating shaft 6, the gear 7 is meshed with the first rack 3 and the second rack 4, a movable frame 8 is fixedly connected to one end of the first rack 3, a maintenance platform 9 is fixedly connected to one end of the second rack 4, a rotating rod 10 is rotatably connected to the outer surface of the movable frame 8, and a movable wheel 11 is fixedly connected to the outer surface of the rotating rod 10.

[0027] In practical use, when it is necessary to inspect equipment of different heights, the staff stands on the inspection platform 9 and starts the servo motor 5, which drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the gear 7 to rotate, which in turn drives the first rack 3 and the second rack 4 to slide up or down respectively. This allows the first rack 3 to push the moving frame 8, and the second rack 4 to push the inspection platform 9 for adjustment, making it convenient for staff to inspect equipment of different heights. When it is necessary to move the position, the staff on the ground can push the base 1 to move it using the moving wheels 11. At the same time, when the inspection platform 9 is not in use, starting the servo motor 5 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the gear 7 to rotate, which in turn drives the first rack 3 and the second rack 4 to slide up or down respectively. This allows the first rack 3 to push the moving frame 8, and the second rack 4 to push the inspection platform 9 for adjustment, so that the moving frame 8 and the inspection platform 9 can be adjusted into the base 1 for storage.

[0028] In this embodiment, a groove 12 is provided on the upper surface of the base 1, and a pin 13 is provided on the inner wall of the groove 12. One end of the pin 13 is fixedly connected to a buckle 14.

[0029] In practical use, after adjusting to a suitable height, insert the pin 13 into the groove 12. Then, use a tool to hammer the buckle 14 so that the pin 13 can be inserted into the ground, thereby fixing the base 1.

[0030] In this embodiment, a groove 15 is provided on the outer surface of the base 1, and the movable frame 8 is slidably connected to the groove 15.

[0031] In practical use, when adjusting the movable frame 8, it can slide through the sliding groove 15, making it easy for the movable frame 8 to be stored inside the base 1.

[0032] In this embodiment, a telescopic rod 16 is fixedly connected to the upper surface of the maintenance platform 9, a sleeve 17 is fixedly connected to the upper surface of the maintenance platform 9, and a knob 18 is rotatably connected to the outer surface of the sleeve 17.

[0033] In practical use, when it is necessary to adjust the railing 21, hold the knob 18 with your hand and turn it.

[0034] In this embodiment, the inner wall of the sleeve 17 is provided with a threaded push rod 19, one end of the threaded push rod 19 is provided with a push block 20, the outer surface of the push block 20 is fixedly connected with a railing 21, the telescopic rod 16 is fixedly connected with the railing 21, and the knob 18 is threadedly connected with the threaded push rod 19.

[0035] In practical use, when the knob 18 is turned, it can drive the threaded push rod 19 to rotate, which in turn allows the threaded push rod 19 to be adjusted out of the sleeve 17. The adjustment of the threaded push rod 19 can push the push block 20 to adjust, which in turn can push the railing 21 to adjust its height, making it convenient for staff of different heights to use. When the threaded push rod 19 is adjusted, the telescopic rod 16 can also push the railing 21 to adjust.

[0036] In this embodiment, the outer surface of the maintenance platform 9 is provided with an installation groove 22, the inner wall of the installation groove 22 is rotatably connected to a vertical rod 23, the outer surface of the vertical rod 23 is fixedly connected to a nut, and the outer surface of the vertical rod 23 is fixedly connected to a worm gear 24.

[0037] In practical use, when the usable area of ​​the maintenance platform 9 is insufficient, use a tool to clamp the nut and rotate it, which can drive the upright 23 to rotate, and drive the worm gear 24 to rotate.

[0038] In this embodiment, a worm gear 25 is rotatably connected to the inner wall of the mounting groove 22, and the worm gear 25 is meshed with the worm wheel 24. An auxiliary platform 26 is fixedly connected to the outer surface of the worm gear 25.

[0039] In practical use, when the worm gear 24 rotates, it can drive the worm 25 to rotate. When the worm 25 rotates, it can drive the auxiliary platform 26 to be adjusted. When adjusted to a suitable distance, the usable area of ​​the maintenance platform 9 can be increased, making it more convenient for workers to use. When it is not necessary to increase the usable area of ​​the maintenance platform 9, the rotation adjustment of the maintenance platform 9 can adjust the maintenance platform 9 to a vertical device, or the maintenance platform 9 can be used as a guardrail to achieve the purpose of protection.

[0040] In this embodiment, a ladder 27 is fixedly connected to the outer surface of the base 1.

[0041] In practical use, when the equipment needs to be inspected, staff can use the escalator 27 to climb up to the maintenance platform 9.

[0042] Working principle: During use, when equipment maintenance is required, staff can climb using the ladder 27 to reach the maintenance platform 9. When maintenance is needed on equipment at different heights, staff stand on the maintenance platform 9 and start the servo motor 5, which drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the gear 7 to rotate, which in turn drives the first rack 3 and the second rack 4 to slide downwards or upwards respectively. This allows the first rack 3 to push the moving frame 8, and the second rack 4 to push the maintenance platform 9 for adjustment, facilitating maintenance of equipment at different heights. When the position needs to be moved, staff on the ground can push the base 1 using the moving wheels 11 to easily achieve the purpose of movement. When the appropriate height is reached, the pin 13 is inserted into the groove 12. Then, use a tool to hammer the buckle 14 so that the pin 13 can be inserted into the ground, thereby fixing the base 1. Simultaneously, when the maintenance platform 9 is not in use, start the servo motor 5 to drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the gear 7 to rotate, which in turn drives the first rack 3 and the second rack 4 to slide up or down respectively. This allows the first rack 3 to push the moving frame 8, and the second rack 4 to push the maintenance platform 9 for adjustment, allowing the moving frame 8 and maintenance platform 9 to be adjusted into the interior of the base 1 for storage. When the usable area of ​​the maintenance platform 9 is insufficient, use a tool to clamp the nut and rotate it, which drives the upright 23 to rotate, which in turn drives the worm gear 24 to rotate. When the worm gear 24 rotates, it drives the worm 25 to rotate, which in turn drives... The auxiliary platform 26 can be adjusted to a suitable distance to increase the usable area of ​​the maintenance platform 9, making it more convenient for staff to use. When it is not necessary to increase the usable area of ​​the maintenance platform 9, the rotation adjustment of the maintenance platform 9 can adjust the maintenance platform 9 to a vertical device, or the maintenance platform 9 can be used as a guardrail for protection. When the railing 21 needs to be adjusted, hold the knob 18 and turn it. When the knob 18 is turned, it can drive the threaded push rod 19 to rotate, which can then adjust the threaded push rod 19 out of the sleeve 17. The adjustment of the threaded push rod 19 can push the push block 20 to adjust, thereby pushing the railing 21 to adjust its height, making it convenient for staff of different heights to use. When the threaded push rod 19 is adjusted, the telescopic rod 16 can also push the railing 21 to adjust.
