Description

Technical Field

[0001] The invention belongs to the technical field of electric power maintenance support platforms, and in particular relates to a temporary insurance transfer platform for high-altitude maintenance operations of electric power towers. Background Art

[0002] Power towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. Power towers are used to support transmission lines. In the power industry, power towers are key structures that support transmission lines, and their stability and safety are of vital importance. Regular maintenance of power towers is an important measure to ensure the stable operation of the power grid. Traditional high-altitude operations usually rely on personal protective equipment such as safety belts and safety ropes, but these equipment can only provide basic protection. For high-altitude maintenance operations that require long-term and complex operations, their convenience and comfort are limited. Workers working at high altitudes are prone to falling tools and themselves due to the number of tools they carry and unstable positioning at high altitudes, which poses installation risks. In addition, when workers take a temporary rest or eat, they need to go up and down the power tower, which is extremely inconvenient. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to solve the problems raised in the above technical background.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a temporary insurance transfer platform for high-altitude maintenance of power towers, which includes a table top, a positioning seat is symmetrically arranged on the inner side of the table top, a connecting rod is arranged on the inner side of the two positioning seats, and a shifting sleeve is arranged on the end of the connecting rod, a pair of blocks is arranged on the side of the table top close to the positioning seat, a shifting screw is arranged between the pair of blocks, and the two shifting sleeves are threadedly sleeved on the shifting screw, a turntable is rotatably arranged on the lower side of the table top, a supporting foot is hingedly arranged on the lower side of the turntable, and a foot ring is arranged at the outer end of the supporting foot.

[0005] An extension rod is arranged inside the supporting foot, and the extension rod is screwed to the supporting foot.

[0006] The table top comprises an inner plate and a flap which are symmetrically arranged, and a hinge is arranged between the inner plate and the flap.

[0007] An inner hole is arranged at a position of the inner plate close to the flap, an insertion rod is arranged at a position of the flap close to the inner hole, and a lever is arranged at an outer side of the insertion rod.

[0008] A rack is arranged on the inner side of the flap, a sleeve rod is sleeved on the outer side of the lever, and a tooth plate is arranged on the lower side of the sleeve rod.

[0009] A return spring is arranged between the shift handle and the sleeve rod.

[0010] A clamping mechanism is arranged on the outside of the positioning seat, and the clamping mechanism includes a shell, and moving blocks are symmetrically arranged inside the shell, a clamping plate is fixedly arranged on the front side of the moving blocks, a driving head is arranged between the moving blocks, and the driving head is clamped with the moving blocks through a clamping block, and a clamping screw is arranged inside the rear side of the shell, and sleeves are symmetrically screwed on the outside of the clamping screw, and hinge rods are hinged between the two sleeves and the driving head.

[0011] A limiting groove is arranged on the inner side of the shell, and a limiting strip is arranged on the outer side of the shift block.

[0012] A tightening screw is arranged inside the clamping plate, a bolt head is arranged at the outer end of the tightening screw, a top plate is arranged outside the clamping plate, and the top plate is screwed to the tightening screw through a sleeve ring.

[0013] The present invention provides a temporary insurance transfer platform for high-altitude operation of power tower maintenance, which has the following beneficial effects: the device realizes stable support and flexible adjustment of the table plate through the precise matching of the positioning seat, connecting rod, shifting sleeve and shifting screw. The design of the clamping mechanism greatly enhances the fixing effect of the table plate and the structure such as the power tower, effectively prevents shaking or tilting caused by factors such as wind force and personnel movement, thereby improving the safety of high-altitude operation; the table plate adopts a combination design of an inner plate and a flap, which can be conveniently expanded through hinge connection. At the same time, the plug rod and the handle design on the flap, as well as the sleeve rod and the tooth plate matched therewith, make the opening and closing operation of the flap simple and fast, further improving the stability and convenience of high-altitude operation. The setting of the turntable and the supporting foot enables the platform to adapt to the operation requirements of different angles and heights. In particular, the extension rod design inside the supporting foot can conveniently adjust the height of the supporting foot through a screw connection, which is convenient for further supporting the table plate, and the stability of the table plate is ensured under the dual action of the positioning seat. The overall design of the platform takes into account the comfort requirements of high-altitude workers. In addition, the surface of the platform can be made of anti-slip material to increase the stability of the operators; at the same time, safety facilities such as guardrails or safety belt hooks can be installed around the platform to further enhance the sense of security of the operators.
