Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a hoisting frame. Background Art

[0002] my country's 35kV to 110kV transmission lines are widely distributed, and most of them use cement poles as wire carriers. According to my country's relevant specifications, transmission lines are equipped with lightning arresters, which are located above the transmission lines and at the highest point of the poles. Grounding wires for lightning arresters are installed at the cement poles, and diagonal wires are installed at the turns or corners of the transmission lines.

[0003] However, since the lightning conductor bracket is about 1.5 meters higher than the concrete pole, it is difficult to replace and install. At the same time, the lightning conductor is heavy. It is very time-consuming and labor-intensive to lift the lightning conductor and fix it on the bracket by manpower. Therefore, it is urgent to design a lifting frame to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a hanging bracket to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hanging frame includes a support ring, and a plurality of evenly distributed rectangular support frames are arranged below the support ring. The outer surface of each support frame is provided with a vertical connection groove, and a push plate is arranged on the connection groove. One end of the push plate connected to the connection groove is provided with a first rotating shaft, and the push plate is movably connected to the connection groove through the first rotating shaft, and the other end of the push plate is provided with a connecting shaft, and the support plate is hinged through the connecting shaft, and the other end of the support plate is provided with a second rotating shaft, which is fixedly connected to the bottom end of the connection groove through the second rotating shaft. Through the arrangement of the support ring, the transmission line pole can be placed inside the support frame, thereby playing the role of supporting the line pole.

[0007] Furthermore, vertical clamping plates are arranged on two opposite side walls in the connecting groove, a plurality of evenly distributed clamping blocks are arranged on the clamping plates and penetrate the supporting plates, and a retractable mechanism is arranged between the clamping blocks and the side walls of the support frame.

[0008] Furthermore, the retractable mechanism includes a limit plate arranged at one end of the clamping block, a second support column is arranged on the other side of the limit plate, a first support column is slidingly sleeved on the other end of the second support column, a spring is arranged outside the first support column and the second support column, one end of the spring is connected to the side wall of the support frame, and the other end is connected to the limit plate.

[0009] In the above technical scheme, through the setting of the limit plate, it can play a limiting role when the clamping block is displaced; through the setting of the spring, when the clamping block is squeezed, the clamping block can be effectively pushed to reset; through the setting of the first support column, it can be effectively ensured that the spring will not be deformed after being squeezed, thereby ensuring the stability of the device.

[0010] Furthermore, three support frames are provided, and the provision of the support frames can effectively support the support ring, thereby improving the stability of the device.

[0011] Furthermore, the two ends of the first rotating shaft match the size between the two clamping blocks, and the two ends of the first rotating shaft are clamped between the clamping blocks, thereby playing a limiting role.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the connection between the supporting ring and the supporting frame, the device is sleeved on the outer end of the wire rod, and the push plate is pressed down. Under the action of the connecting shaft, the connecting shaft is displaced to the outside, and the height of the pushing plate is reduced, which pushes the supporting plate to a horizontal direction, so that the supporting plate is supported on the outer surface of the supporting frame, thereby increasing the supporting area of ​​the supporting ring, effectively avoiding manual lifting, and greatly improving work efficiency.

[0021] like Figure 1-4 As shown, the utility model provides a hanging frame, including a support ring 2, and three evenly distributed rectangular support frames 1 are arranged below the support ring 2. Through the arrangement of the support frame 1, the support ring 2 can be effectively supported, thereby improving the stability of the device; through the arrangement of the support ring 2, the transmission line pole can be placed inside the support frame 1, thereby playing the role of supporting the line pole. A vertical connection groove 13 is opened on the outer surface of each support frame 1, and a vertical clamping plate 110 is arranged on the opposite side walls of the connection groove 13. The clamping plate 110 is penetrated by the support plate 110 and is provided with a plurality of evenly distributed clamping blocks 14, and a retractable mechanism is arranged between the clamping block 14 and the side wall of the support frame 1. A push plate 15 is arranged on the connection groove 13. Specifically, a first rotating shaft 16 is arranged at one end of the push plate 15 connected to the connection groove 13, and the two ends of the first rotating shaft 16 match the size between the two clamping blocks 14, and the two ends of the first rotating shaft 16 are arranged between the clamping blocks, thereby playing a limiting role. The push plate 15 is movably connected to the connecting groove 13 through the first rotating shaft 16. A connecting shaft 17 is provided at the other end of the push plate 15, and a support plate 18 is hinged through the connecting shaft 17. A second rotating shaft 19 is provided at the other end of the support plate 18, which is fixedly connected to the bottom end of the connecting groove 13 through the second rotating shaft 19.

[0022] like Figure 4As shown, the retractable mechanism includes a limit plate 111 arranged at one end of the clamping block 14. Through the setting of the limit plate 111, it can play a limiting role when the clamping block 14 is displaced; a second support column 114 is arranged on the other side of the limit plate 111, and the other end of the second support column 114 is slidably sleeved with a first support column 113, and the first support column 113 and the second support column 114 are outer-mounted with a spring 112, one end of the spring 112 is connected to the side wall of the support frame 1, and the other end is connected to the limit plate 111.
