Problems solved by technology

[0003] When large equipment such as cranes, excavators, concrete mixer trucks, pump trucks, ships, and sand dredgers pass under the power transmission cable, because there are no warning facilities on the power transmission cable and the color of the power transmission cable is gray, the operation of large equipment It is easy for the driver to ignore the power transmission cable, so that the height of the tall and protruding parts of the large equipment (such as the boom of the crane, the bucket of the excavator, the lifting device of the sand dredger, etc.) A part close to the transmission cable causes a discharge accident, or the tall protruding part of the large equipment hooks and cuts the transmission cable and damages the transmission cable, resulting in tripping and power outage accidents

Embodiment 1

[0058] A power transmission cable suspension distance limiting device, comprising an insulating suspension mechanism 1 and an insulating distance limiting rod 2 .

[0059] Such as figure 1As shown, the insulating suspension mechanism 1 includes a base 1-1, a first support plate 1-2, a second support plate 1-3, a suspension plate 1-4, and a fixing plate 1-5.

[0060] Such as figure 1 As shown, the base 1-1 includes a cylindrical body 1-1-1 with an open upper surface and a filling body 1-1-2 filled in the cylindrical body 1-1-1. The cylinder body 1-1-1 adopts plastic cylinder, and the filling body 1-1-2 adopts filling glue.

[0061] Such as image 3 As shown, the lower end of the first support plate 1-2 and the lower end of the second support plate 1-3 are inserted into the filling glue, and the filling glue seals the first support plate 1-2 and the second support plate 1-3. Fixed in a plastic barrel.

[0062] Such as figure 1 As shown, one end of the suspension plate 1-4 ...

Embodiment 2

[0090]The present embodiment 2 is the same as the embodiment 1, the difference is that in the transmission cable suspension distance limiting device of the present embodiment 2, the insulation fixing mechanism 4 adopts an automobile mechanical door lock, which is a prior art , directly adopts the automobile mechanical door lock, which can be directly purchased and used, and is easy to assemble.

Embodiment 3

[0092] The present embodiment 3 is the same as the embodiment 1, the difference is that in the transmission cable suspension distance limiting device of the present embodiment 3, such as Figure 7 As shown, the upper end of the first support plate 1-2 and the upper end of the second support plate 1-3 are both provided with a torsion spring buckle 5 for pressing the power transmission cable 100 to the upper end surface of the base 1-1.

[0093] When it is necessary to use the torsion spring buckle 5 to press the power transmission cable 100 on the upper end surface of the base 1-1:

[0094] First, the torsion spring buckle 5 is broken off, and the power transmission cable 100 is dropped on the upper surface of the base 1-1. Then, the torsion spring buckle 5 is released, and the torsion spring buckle 5 is pressed against the power transmission cable 100 under the action of the torsion spring preload. Finally, according to the steps in Embodiment 1, the end of the suspension boa...

Abstract

The invention discloses a power transmission cable suspension distance limiting device, and relates to the technical field of power transmission cable protection. The device comprises an insulating suspension mechanism and an insulating distance limiting rod, wherein the insulating suspension mechanism comprises a base, a first supporting plate, a second supporting plate and a suspension plate, the lower end of the first supporting plate and the lower end of the second supporting plate are connected with the base, one end of the suspension plate is hinged to the upper end of the first supporting plate, the end, which is away from the first supporting plate, of the suspension plate is fixed to the second supporting plate through a suspension plate fixing piece, and the two ends of the insulating distance limiting rod are connected with the base through insulating connecting rods. According to the invention, a driver operating large-scale equipment can notice the power transmission cable, so that the driver of the large-scale equipment can adjust the height of a raised part of the large-scale equipment in time, discharge accidents caused by the fact that the raised part of the large-scale equipment is close to the power transmission cable are avoided, and tripping and power failure accidents caused by the fact that the raised part of the large-scale equipment hooks and cuts off the power transmission cable to damage the power transmission cable are avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission cable protection, in particular to a power transmission cable suspension distance limiting device. Background technique [0002] With the rapid development of the national economy and the continuous expansion of cities, power transmission cables are spread across urban and rural areas, roads, bridges and other areas. [0003] When large equipment such as cranes, excavators, concrete mixer trucks, pump trucks, ships, and sand dredgers pass under the power transmission cable, because there are no warning facilities on the power transmission cable and the color of the power transmission cable is gray, the operation of large equipment It is easy for the driver to ignore the power transmission cable, so that the height of the tall and protruding parts of the large equipment (such as the boom of the crane, the bucket of the excavator, the lifting device of the sand dredger, etc.) Some of the...
