Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology for overhead power lines, specifically an aerial installation platform for high-voltage line aviation warning balls. Background Technology

[0002] In Africa, most areas of 60kV and above high-voltage transmission lines require the installation of aerial warning spheres on overhead ground wires. When power lines cross special sections such as deep canyons, densely populated areas, lakes, and swamps, the on-site construction site is limited, there is no construction access under the line, and lifting machinery such as cranes and insulated bucket trucks cannot enter the work area. Aerial warning spheres in the middle of the line cannot be installed on the ground. Therefore, an aerial installation platform for high-voltage line aerial warning spheres is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide an aerial installation platform for high-voltage line aviation warning balls to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aerial installation platform for high-voltage line aviation warning balls, comprising multiple tower crossarms and an overhead ground wire connecting the multiple tower crossarms. A lifting pulley is installed on the overhead ground wire, and a suspended basket connected to the lifting pulley is provided below the lifting pulley. A universal pulley and a safety wire clamp are respectively installed on the overhead ground wire, wherein the universal pulley is located in the forward direction of the suspended basket, and the safety wire clamp is located in the opposite direction of the forward direction of the suspended basket. A manual winch connected to the universal pulley via a traction rope is installed on the suspended basket and is configured to control the movement of the suspended basket on the overhead ground wire.

[0005] As a further embodiment of this utility model: the manual winch includes a winch base installed inside the basket, a winch gear for winding the traction rope is installed on the winch base, a wheel card for limiting the rotation of the winch gear is also installed on the winch base, and a winch handle for driving the winch gear to rotate synchronously is installed on the winch base.

[0006] As a further embodiment of this utility model: lifting lugs are installed at the four corners of the upper surface of the suspended basket, and the four lifting lugs are arranged in groups of two. Each group of lifting lugs is connected to both ends of a lifting rope, and the middle part of the lifting rope is suspended on the lifting pulley.

[0007] As a further embodiment of this utility model: the safety cable clamp is equipped with a rope for braking the suspended platform, and the other end of the rope is connected to the suspended platform.

[0008] As a further embodiment of this utility model: the suspended basket is welded from steel plates and square steel, and its four sides are hollow.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] This application enables the work platform to move autonomously in the air by configuring a manual winch and omnidirectional pulleys. The overhead ground wire is locked by a safety wire clamp to stop the slippage during operation. This allows for the installation of aviation warning balls for power lines at high altitudes, reducing the need for site requisition for construction access, improving construction efficiency, and saving construction costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See also Figure 1-3 In this embodiment of the utility model, an aerial installation platform for a high-voltage line aviation warning ball includes multiple tower crossarms and an overhead ground wire 1 connecting the multiple tower crossarms. A lifting pulley 2 is installed on the overhead ground wire 1, and a basket 5 connected to the lifting pulley 2 is provided below it. A universal pulley 4 and a safety wire clamp 3 are respectively installed on the overhead ground wire 1, wherein the universal pulley 4 is located in the forward direction of the basket 5, and the safety wire clamp 3 is located in the opposite direction of the forward direction of the basket 5. A manual winch 6 connected to the universal pulley 4 by a traction rope is installed on the basket 5 and is configured to control the movement of the basket 5 on the overhead ground wire 1.

[0017] Specifically, the installation platform is equipped with lifting wire ropes, basket locking safety ropes, wire clamp fixing ropes, and personal safety belts, which together constitute multiple safety measures for the workers, making the equipment safe and reliable to use. The entire crossing section can be installed in one operation, eliminating the need for repeated climbing of iron towers and overhead lines.

[0018] See also Figure 2 In one embodiment, preferably, the manual winch 6 includes a winch base 61 installed inside the suspended basket 5. A winch gear 64 for winding the traction rope is installed on the winch base 61. A disc clip 62 is also installed on the winch base 61 to restrict the rotation of the winch gear 64. When the end of the disc clip 62 engages with the teeth of the winch gear 64, it restricts the rotation of the winch gear 64. A winch handle 63 is installed on the winch base 61 to drive the winch gear 64 to rotate synchronously. Furthermore, rotating the winch handle 63 drives the winch gear 64 to rotate and winds the traction rope around the winch gear 64, thereby providing forward power to the suspended basket 5. During operation, the manual winch 6 tightens the traction rope to provide forward power. When stopping and sliding, a safety wire clamp 3 is used to secure the overhead ground wire 1 to achieve braking, while simultaneously engaging the disc clip 62 into the winch gear 64.

[0019] See also Figure 1 In one embodiment, preferably, lifting lugs are installed at the four corners of the upper surface of the suspended basket 5, and the four lifting lugs are arranged in groups of two. Each group of lifting lugs is connected to both ends of a lifting rope, and the middle of the lifting rope is suspended on the lifting pulley 2. In this way, the suspended basket 5 can be fixed below the lifting pulley 2.

[0020] See also Figure 1 In one embodiment, preferably, the safety cable clamp 3 is equipped with a rope for braking the suspended platform 5, and the other end of the rope is connected to the suspended platform 5.

[0021] Specifically, in the working state, the safety wire clamp 3 is locked on the overhead ground wire 1 in the opposite direction of forward movement, realizing aerial sliding braking; in the forward movement state, the safety wire clamp 3 is opened, the wire clamping groove is released, and then the work platform can move forward under the traction of the manual winch 6.

[0022] See also Figure 1 In one embodiment, in order to ensure that the suspended platform 5 is less affected by wind during operation, in this embodiment, preferably, the suspended platform 5 is welded from steel plates and square steel, and its four sides are hollow. Furthermore, since the suspended platform 5 is open on all sides, when the wind is hoisted, it can pass through the suspended platform 5 smoothly without causing excessive contact with the suspended platform 5, so as to ensure that the suspended platform 5 will not sway significantly during use.
