Description

Technical Field

[0001] The present invention relates to the field of electric power construction, and particularly to an auxiliary platform for electric power construction of utility poles. Background Art

[0002] During electric power maintenance projects, it is often necessary for operators to climb to the top of the utility pole. At this time, the operators are at a high altitude. During maintenance, the maintenance tools and components to be replaced can only be stored in a tool bag and carried by the maintenance personnel for maintenance operations. This results in frequent searching for tools or components during the maintenance process, causing great inconvenience to the maintenance operations. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary platform for electric power construction of utility poles to overcome the above-mentioned defects in the prior art.

[0004] An auxiliary platform for electric power construction of utility poles according to the present invention includes a frame body for fixing on the utility pole. Two loading platforms are arranged on the frame body. The frame body includes two symmetrically arranged frame rods on the left and right. An expansion rod is slidably connected inside the frame rod. The upper end of the expansion rod and the lower end of the frame rod are respectively rotatably connected with a rod sleeve. A connecting rod is arranged between the two rod sleeves on the left and right. The two ends of the connecting rod respectively extend towards the two rod sleeves on both sides and are slidably connected with the two rod sleeves. A second support rod is rotatably connected between the rod sleeve on the upper left side and the rod sleeve on the lower right side. A first support rod is rotatably connected between the rod sleeve on the upper right side and the rod sleeve on the lower left side. The first support rod and the second support rod intersect and are rotatably connected. A clamping roller is rotatably connected to the rod sleeve. The four clamping rollers can clamp on the utility pole. Fixed seats are fixed on the upper end faces of the two rod sleeves on the upper side. The two loading platforms are respectively fixed on the two fixed seats.

[0005] Further, the first support rod and the second support rod intersect and are rotatably connected, so that the four clamping rollers can open and close synchronously. By adjusting the distance between adjacent clamping rollers, it can be adapted to utility poles of different diameters. The frame body is clamped on the utility pole by the four clamping rollers, so that the loading platform can be erected on the utility pole to facilitate the maintenance operations of the operators.

[0006] Further, the cross-section of the connecting rod perpendicular to its sliding direction is "I"-shaped. A limiting groove is arranged in the connecting rod along its sliding direction. A through hole penetrating the rod sleeve is opened on the front end face of the rod sleeve. A limiting pin penetrating the limiting groove is fixed in the through hole.

[0007] Through the above technical solution, the setting of the connecting rod can extend the distance between the two rod sleeves. At the same time, the "I"-shaped connecting rod can effectively increase its bending strength.

[0008] Furthermore, a rod base is fixed on the telescopic rod, a threaded block is fixed on the support rod, a first threaded rod passing through the threaded block is rotatably connected in the rod base, and the first threaded rod is threadedly connected with the threaded block.

[0009] Through the above technical solution, rotating the first threaded rod can adjust the length of the telescopic rod extending out of the support rod.

[0010] Furthermore, roller shafts are fixedly arranged at both ends of the clamping roller. The four roller shafts at the front side respectively penetrate through the rod sleeves and are rotatably connected with the rod sleeves. The upper ends of the two telescopic rods are respectively rotatably connected to the two roller shafts at the upper side, and the lower ends of the two support rods are respectively rotatably connected to the roller shafts at the lower side.

[0011] Through the above technical solution, after rotating the first threaded rod, the length of the telescopic rod extending out of the support rod changes, thereby adjusting the distance between the upper and lower rod sleeves. Under the cross support of the first support rod and the second support rod, the distance between the left and right rod sleeves changes accordingly.

[0012] Furthermore, a limiting frame is arranged on one side of the frame body. The limiting frame includes two intersecting limiting components which are rotatably connected between them. The limiting component includes a central block, two threaded tubes and two second threaded rods. The two threaded tubes are symmetrically arranged and fixed on the outer periphery of the central block. The two second threaded rods are respectively threadedly connected in the threaded tubes. A sleeve is fixed at one end of the second threaded rod away from the central block. The four sleeves can be respectively sleeved on the roller shafts at the rear ends of the four clamping rollers.

[0013] Through the above technical solution, the present invention can be completely sleeved on the electric pole, thereby ensuring the connection stability between the present invention and the electric pole.

[0014] Furthermore, connecting bolts are threadedly connected in the four roller shafts at the rear side, and limiting plates which can abut against the sleeves are fixedly arranged at one ends of the four connecting bolts away from the clamping roller.

[0015] Through the above technical solution, the arrangement of the limiting plates can ensure that the sleeves are limited on the roller shafts.

[0016] Furthermore, a central column is fixedly arranged on the central block on one side close to the first support rod, and a connection groove is formed on the central block on the side away from the first support rod. The central column is rotatably connected in the connection groove.

[0017] Through the above technical solution, the rotational connection between the central column and the connection groove can increase the connection strength and connection stability between the two central blocks.

[0018] Furthermore, two symmetrically arranged limit bolts are fixedly installed on the central block on one side close to the first support rod. A guiding groove penetrating through its thickness is formed on the central block on the side far from the first support rod. The guiding groove is arc-shaped with the central block as the center. The limit bolt penetrates through the guiding groove and is slidably connected along it. A limit plate is arranged on the side of the central block with the guiding groove far from the first support rod. Both ends of the limit plate are sleeved on the limit bolt, and a nut threadedly connected to the outer periphery of the limit bolt is used to abut the limit plate against the central block.

[0019] Through the above technical solution, after the nut is tightened, the limit plate is precisely abutted against the central block, thereby limiting the relative rotation between the two central blocks, and thus increasing the limiting effect of the limit frame on the four roller shafts.

[0020] The beneficial effects of the present invention are as follows: The first support rod and the second support rod intersect and are rotatably connected, so that the four clamping rollers can be opened and closed synchronously. By adjusting the distance between adjacent clamping rollers, it can be applied to utility poles with different diameters. The frame body is clamped on the utility pole through the four clamping rollers, so that the loading platform can be erected on the utility pole to facilitate the maintenance work of operators.

As used herein, the terms "upper and lower" and "left and right" are not limited to their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent. The specific features of a power construction auxiliary platform for utility poles will be described in detail below: An embodiment of the present invention: Referring to Figures 1-6 , the present invention provides a power construction auxiliary platform for utility poles, including a frame for fixing on a utility pole. There are two loading platforms 10 arranged on the frame. The frame includes two symmetrically arranged frame rods 30 on the left and right. A telescopic rod 35 is slidably connected inside the frame rod 30. The upper end of the telescopic rod 35 and the lower end of the frame rod 30 are both rotatably connected with a rod sleeve 31. A connecting rod 33 is arranged between the two rod sleeves 31 on the left and right sides. Both ends of the connecting rod 33 extend towards the two rod sleeves 31 on both sides and are slidably connected with the two rod sleeves 31. A second support rod 37 is rotatably connected between the rod sleeve 31 on the upper left side and the rod sleeve 31 on the lower right side. A first support rod 32 is rotatably connected between the rod sleeve 31 on the upper right side and the rod sleeve 31 on the lower left side. The first support rod 32 and the second support rod 37 intersect and are rotatably connected. A clamping roller 20 is rotatably connected to the rod sleeve 31. The outer periphery of the clamping roller 20 is recessed inward to form a concave surface, so that it can better fit on the outer periphery of the utility pole. The four clamping rollers 20 can clamp on the utility pole. Fixed seats 11 are fixed on the upper end faces of the two rod sleeves 31 on the upper side. The two loading platforms 10 are respectively fixed on the two fixed seats 11.

[0025] Referring to Figure 5 , the cross-section of the connecting rod 33 perpendicular to its sliding direction is "I"-shaped. A limiting groove 331 is arranged inside the connecting rod 33 along its sliding direction. A through hole penetrating the rod sleeve 31 is opened on the front end face of the rod sleeve 31, and a limiting pin 34 penetrating the limiting groove 331 is fixed in the through hole.

[0026] Referring to Figure 4, a rod base 351 is fixed on the telescopic rod 35, a threaded block 301 is fixed on the support rod 30, a first threaded rod 36 passing through the threaded block 301 is rotatably connected inside the rod base 351, and the first threaded rod 36 is threadedly connected with the threaded block 301.

[0027] Refer to Figures 2-4 , roller shafts 21 are fixedly provided at both ends of the clamping roller 20. The four roller shafts 21 on the front side respectively pass through the rod sleeve 31 and are rotatably connected with the rod sleeve 31. The upper ends of the two telescopic rods 35 are respectively rotatably connected to the two roller shafts 21 on the upper side, and the lower ends of the two support rods 30 are respectively rotatably connected to the two roller shafts 21 on the lower side.

[0028] Refer to Figure 2 , Figure 6 , a limit frame is arranged on one side of the frame body. The limit frame includes two intersecting limit components which are rotatably connected between them. The limit component includes a central block 40, two threaded tubes 41 and two second threaded rods 43 (the threads on the outer periphery of the second threaded rod 43 are not shown). The two threaded tubes 41 are symmetrically arranged and fixed on the outer periphery of the central block 40. The two second threaded rods 43 are respectively threadedly connected inside the threaded tubes 41. A sleeve 42 is fixed at one end of the second threaded rod 43 away from the central block 40. The four sleeves 42 can be respectively sleeved on the roller shafts 21 at the rear ends of the four clamping rollers 20. Connecting bolts 50 are threadedly connected inside the four roller shafts 21 on the side. Limit plates 51 which can abut against the sleeves 42 are fixedly provided at one ends of the four connecting bolts 50 away from the clamping roller 20. A central column 46 is fixedly provided on the central block 40 on the side close to the first support rod 32. A connecting groove 401 is opened on the central block 40 on the side away from the first support rod 32. The central column 46 is rotatably connected in the connecting groove 401. Two symmetrically arranged limit bolts 47 are fixedly provided on the central block 40 on the side close to the first support rod 32. A guiding groove 402 penetrating through its thickness is opened on the central block 40 on the side away from the first support rod 32. The guiding groove 402 is arc-shaped with the central block 40 as the center of the circle. The limit bolts 47 pass through the guiding groove 402 and are slidably connected along it. A limit plate 44 is arranged on the side of the central block 40 with the guiding groove 402 away from the first support rod 32. Both ends of the limit plate 44 are sleeved on the limit bolts 47. A nut 45 which can abut the limit plate 44 against the central block 40 is threadedly connected on the outer periphery of the limit bolts 47. The surfaces of the central block 40 and the limit plate 44 close to each other are both frosted surfaces.

[0029] When the present invention is in use, after the operator climbs along the utility pole to its top, the present invention is fixed to the top of the utility pole. According to the diameter of the utility pole, the first threaded rod 36 is rotated, so that the rod seat 351 moves in the direction close to the threaded block 301, thereby reducing the distance between the upper and lower roller shafts 21. Under the cross support of the first support rod 32 and the second support rod 37, the distance between the left and right roller shafts 21 is increased, so that the distance between the left and right clamping rollers 20 is increased, so that the left and right clamping rollers 20 can be clamped on the utility pole.

[0030] Then, the first threaded rod 36 is reversed, so that the distance between the left and right clamping rollers 20 is reduced until the left and right clamping rollers 20 are clamped on the utility pole. Finally, the positions of the four sleeves 42 on the limit frame are adjusted according to the positions of the four roller shafts 21.

[0031] The two center blocks 40 are rotated, and at the same time, the second threaded rod 43 is rotated, so that the second threaded rod 43 extends or contracts along the threaded tube 41, thereby adjusting the positions of the four sleeves 42 to align with the four roller shafts 21. Then, the four sleeves 42 are sleeved on the four roller shafts 21.

[0032] At this time, the four connecting bolts 50 are screwed into the four roller shafts 21 until the four limiting plates 51 are respectively in contact with the four sleeves 42, thereby restricting the sleeves 42 on the roller shafts 21.

[0033] Then, the nut 45 is tightened so that the limiting plate 44 is in close contact with the center block 40, thereby restricting the rotation between the two center blocks 40.

[0034] When the operator is performing maintenance work, the maintenance tools and components can be placed on the loading platform 10.

[0035] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present invention. They all fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
