Reusable electricity guard hanging slot group for construction of hanging basket

Abstract

The invention discloses a reusable electricity guard hanging slot group for construction of a hanging basket. The electricity guard hanging slot group is used for protecting a hanging basket during construction of an interchange spanning an electrified railway. The electricity guard hanging slot group is composed of a plurality of electricity guard hanging slots, hinging self-locking type suspension devices, centripetal differential pressure type water connecting pipes, fasteners and insulation wrapping baffles. The safety reliability of hanging of the electricity guard hanging slots can be guaranteed through the hinging self-locking type suspension devices; the electricity guard hanging slots can be guaranteed to be water-tight through the centripetal differential pressure type water connecting pipes; the strong wind resistance and impact resistance abilities of the upper retaining parts of the baffles can be enhanced through hinging supporting frames of the insulation wrapping baffles. As the structures of the electricity guard hanging slots are adopted, the non-deformation can be guaranteed during transportation and use, the loading space is saved during stacking and transportation, the transportation cost is lowered, the damage to the insulation plates is not caused, and the electricity guard hanging slots are guaranteed to be reusable, so that the reusable electricity guard hanging slot group has significant technical and economic benefits.

Description

technical field [0001] The patent of the present invention relates to the structure, suspension mode, and water pipe connection mode between the hanging troughs and the hanging troughs of the reusable hanging basket construction anti-electricity hanging trough group used for the construction protection of the hanging troughs on the electrified railway overpass. Background technique [0002] The hanging basket used in the construction of the continuous beam of the upper-span electrified railway overpass is relatively close to the 27.5KV railway catenary, and the train is running at high speed below, and the construction water, rainwater and materials during the construction process are very easy to fall to On the 27.5KV railway catenary or on the railway, the catenary is blown due to a short circuit, causing traffic accidents and electric shock casualties. Therefore, the hanging baskets in the construction of the upper-span electrified railway overpass must take anti-electric...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the connection method of the water-through seat tube between the anti-electricity hanging groove and the anti-electricity hanging groove, it is easy to cause water leakage and electric leakage, and the safety and reliability are poor

[0006] 2. Due to the structural problems of the anti-electricity hanging slot, the anti-electricity hanging slot and the anti-electricity hanging slot cannot be stacked during transportation. If they are stacked, the insulation board of the anti-electricity hanging slot will be damaged, and the entire anti-electricity hanging slot will be scrapped. Unusable, severely delayed construction period, and cannot be reused

[0008] Since the anti-electricity hanging slots cannot be stacked together, short-distance transportation, placement, and hoisting at the construction site are very difficult, labor-intensive and time-consuming, and are likely to cause damage, which increases the time for short-distance transportation, placement, and hoisting. the cost of

[0009] 3. Due to the unreasonable structure and poor rigidity of the existing anti-electricity hanging groove, it is easy to be deformed and scrapped when it is removed after one use, and it cannot be reused, resulting in waste

[0010] 4. Since the hook of the suspender of the existing anti-electricity hanging trough suspension device is not provided with a device to prevent the opening of the force, when the force on the hook is slightly larger, the hook is easily deformed and opened, and the safety of the anti-electricity hanging trough cannot be guaranteed. suspension safety

[0011] Some have welded the opening of the suspender hook into a closed type, which will not open after being stressed, but the suspender of the closed hook cannot be removed. The fixed suspender increases the difficulty of installation and affects the stacking of the anti-electricity hanging groove , increasing the loading space

[0012] 5. After the existing anti-electricity hanging grooves are connected, the insulating plates of the adjacent electricity-proof hanging grooves are not closely pasted, resulting in exposed angle steel along the upper edge, which is not conducive to the safety and reliability of high-voltage protection

[0013] 6. The lower end of the insulation-wrapped baffle of the existing anti-electricity hanging groove cannot completely cover the upper edge angle steel and self-drilling screws of the anti-electricity hanging groove, so that the metal part is exposed near the high-voltage line, which does not play the role of insulation and isolation. poor performance

The baffle is not riveted with the steel frame and has poor impact resistance
