Problems solved by technology

Due to the variety of structures and sizes of on-site equipment, it is impossible to reliably fix the safety belt suspension device. Maintenance personnel often hang the safety belt on the porcelain bottle, which may cause personal injury and equipment damage due to porcelain bottle breakage.
[0003] The bases of various equipment in the substation are made of circular equal-diameter cement poles and steel poles. There is no suitable safety belt suspension point on the pole body, and there is a disadvantage of "low hanging and high use" of safety belts when hanging on the horizontal structure. Many structural designs It is also not possible to add other types of seat belt hangers
When performing equipment maintenance, the maintenance personnel are very passive while standing on the equipment structure or insulation ladder, and the safety belt cannot effectively protect the safety
Due to the dense arrangement of various large-scale equipment, the use of lift trucks is not only costly, but also the lift trucks cannot be approached
In particular, cement rods are not easily bolted due to their smooth surfaces, and cannot be fixed by welding
[0004] There is an existing safety belt suspension device applied to electric poles, which is generally fixed to the electric pole by holding the electric pole tightly with a hoop. One hoop improves the reliability of fixing by increasing the number of fixed positions, but the vertical spacing of the existing hoops is generally fixed and cannot be adjusted. Under different working conditions, the maintenance has a certain degree of difficulty. limitations, not suitable for a variety of working conditions, poor adaptability

Embodiment 1

[0032] like Figures 1 to 4 As shown, the present invention provides a widely applicable fixed safety belt suspension device, comprising a riser 1, a safety belt hanging ring 2 and a fixed structure, the safety belt hanging ring 2 is located at the top of the riser 1, and the fixed structure is located at the vertical The bottom end of the pipe 1 and the riser 1 are fixed together with the electrical equipment through a fixed structure, and a safety belt suspension device is provided to ensure the personal safety of the maintenance personnel when repairing the equipment.

[0033]In this embodiment, the fixed structure and the standpipe 1 are detachably fixed together, so that the fixed structure and the standpipe can be detachable, so that when maintaining different electrical equipment, different fixing structures can be selected to match with the standpipe, so as to achieve maintenance efficiency. Purpose, and the fixing structure specifically includes a utility pole fixing ...

Embodiment 2

[0038] The difference between this embodiment and the first embodiment lies in that the structures of the upper hoop and the lower hoop are different.

[0039] In this example, if Figures 5 to 6 As shown, the upper hoop 32 includes a first upper hoop piece 322 and a second upper hoop piece 323, and the first upper hoop piece 322 and the second upper hoop piece 323 are connected by first bolts 324 and encircled to form the The upper hoop 32, the first upper hoop piece 322 and the second upper hoop piece 323 are all provided with an upper adjustment hole 325, and the upper adjustment hole 325 is provided with a plurality, and the first bolt 324 passes through different upper adjustment holes 325 By changing the enclosing inner diameter of the upper hoop 32, the upper hoop can be applied to utility poles of different sizes, which greatly improves the applicability of the fixed safety belt suspension device, that is, the fixed safety belt suspension device is widely applicable. ...

Embodiment 3

[0045] The difference between this embodiment and the first embodiment is that the riser is a telescopic riser.

[0046] In this example, if Figure 7 As shown, the standpipe 1 includes an inner standpipe 11 and an outer standpipe 12. The inner standpipe 11 is sleeved in the outer standpipe 12 and can be telescopically arranged along the axial direction of the outer standpipe 12, so that the overall length of the standpipe can be adjusted if necessary. At the same time, the overall length of the standpipe can be adjusted by adjusting the inner standpipe and the outer standpipe, so that it can be well adapted to different working conditions during operation, without replacing the entire standpipe, which greatly improves the work of maintenance personnel efficiency, and the safety belt hanging ring 2 is detachably connected to the top of the inner riser 11 through a fastening structure, so that the safety belt hanging ring 2 and the inner riser 11 are detachably connected, so th...

Abstract

The invention provides a wide-range fixed safety belt suspension device. The wide-range fixed safety belt suspension device comprises a vertical pipe, a safety belt hanging ring and a fixing structure, wherein the safety belt hanging ring is arranged at the top end of the vertical pipe, the fixing structure is arranged at the bottom end of the vertical pipe, the vertical pipe is fixed together with the electric equipment through the fixing structure, the fixing structure comprises a telegraph pole fixing structure, the telegraph pole fixing structure comprises a connecting block and a hoop fixedly connected with the connecting block, the hoop comprises an upper hoop and a lower hoop, the upper hoop and the lower hoop are arranged at intervals in the axial direction, the upper hoop and thelower hoop are movably arranged in the axial direction of the connecting block so as to adjust the position of the hoop fixed on the telegraph pole, so that cross arms are arranged at the telegraph pole needing to be fixed or separated by other electric equipment, the axial spacing distance between the upper hoop and the lower hoop can be adjusted by adjusting the axial spacing between the upper hoop and the lower hoop, so that the hoop can avoid those cross arms or electric equipment which can form a barrier, the adaptability of the fixed safety belt suspension device is well improved, namelythe fixed safety belt suspension device is wide in application range.

Description

technical field [0001] The invention relates to a safety protection device for power equipment maintenance, in particular to a widely applicable fixed safety belt suspension device. Background technique [0002] During the maintenance and construction of large-scale power transmission and transformation equipment, the operator must strictly follow the operating procedures for safety protection. When working at heights, the operator should fasten the safety belt, and at the same time connect the safety belt to the equipment structure reliably and firmly. It can effectively prevent the operator from stepping on the air and falling, and using the seat belt correctly is an important measure to prevent personal accidents. When overhauling electrical equipment such as coupling capacitors and arresters with voltage levels of 35KV and 110KV, there should be safe and reliable anti-fall measures. Due to the variety of structures and sizes of on-site equipment, it is impossible to rel...
