Description

Technical Field

[0001] This utility model belongs to the technical field of safety ropes for substation engineering, and in particular relates to a safety rope suspension device for substation engineering. Background Technology

[0002] Power transmission and transformation engineering refers to the engineering field involving power transmission and transformation. It mainly involves the design, construction, operation, and maintenance of facilities such as high-voltage transmission lines, substations, and power distribution systems. These operations often require workers to work at heights. To ensure the safety of construction personnel, safety ropes are frequently used in power transmission and transformation engineering construction. These ropes can quickly brake and lock falling objects within a limited distance, effectively preventing the safety of ground personnel from being threatened when suspended workpieces accidentally fall, while also protecting the suspended workpieces from damage.

[0003] The existing safety rope suspension device has a relatively simple structure and cannot be flexibly adjusted according to the specifications of the power transmission line. It has poor compatibility. If it is clamped too tightly to the outside of the power transmission line during use, it is not only easy to cause movement to get stuck, but also easy to wear and tear after long-term use. Utility Model Content

[0004] The purpose of this invention is to provide a safety rope suspension device for substation engineering. Through the action of the clamps, when the fixed shell is pulled forward, the protective wheel inside the clamps also rolls on the outside of the transmission line. This transforms the sliding friction between the device and the transmission line into rolling friction, allowing the device to slide more smoothly on the outside of the transmission line. Simultaneously, the distance between the two clamps can be adjusted according to the specifications of the transmission line. This adjustable suspension device avoids the clamps from excessively clamping the transmission line, causing movement to become stuck, and also avoids increasing the friction between the clamps and the transmission line, leading to wear on the outside of the transmission line. This solves the problem that existing safety rope suspension devices, if clamped too tightly to the outside of the transmission line, are prone to movement jamming during use and wear and tear over long-term use.

[0039] The operation process of the embodiment is as follows: when the device is used, the worker wears the safety rope on the waist, passes the safety rope through the mounting ring 2 on one side of the fixed shell 1, buckles the safety lock, fixes the fixed shell at one end of the safety rope, and then opens the hydraulic cylinder 3. The output shaft of the hydraulic cylinder 3 drives the movable block 4 at one end to move, the movable block 4 drives the clamping plates 6 on both sides to move through the linkage, so that the clamping plates 6 on both sides clamp the power transmission line, so that the clamping plates 6 can slide outside the power transmission line. Then, the mounting strip 12 is clamped into the mounting groove 11, the threaded holes 19 at one end of the mounting plate 10 are aligned with the threaded holes 19 on one side of the fixed plate 18, and then the bolts and other tools are screwed into the threaded holes 19. The connecting plate 13 can be fixed above the clamping plates 6. When the fixed shell 1 is pulled to slide forward, the protection wheels 9 inside the clamping plates 6 also roll outside the power transmission line.

At the same time, the device can adjust the distance between the two clamping plates 6 according to the specifications of the power transmission line. This adjustable suspension device can avoid excessive clamping of the clamping plates 6 on the power transmission line, causing the action to be stuck, and also avoid increasing the friction between the clamping plates 6 and the power transmission line, causing wear on the outside of the power transmission line.
