Abstract

The utility model relates to an interval-adjustable safety belt suspension device for maintaining an isolating switch and relates to the technical field of power construction safety protection tools. The interval-adjustable safety belt suspension device comprises a pair of fixed clamping bodies and two vertical rods, wherein each fixed clamping body is formed by connecting an upper clamping plate and a lower clamping plate through the penetration of a pair of connecting bolts; the two vertical rods are fixed to the two lower clamping plates respectively; a safety belt hanging rope is connected between the two vertical rods; a length adjustable mechanism of the safety belt hanging rope is arranged on at least one vertical rod. Compared with other safety belt suspension devices, the interval-adjustable safety belt suspension device has the advantages that two ends of the safety belt hanging rope are adjustable; when the safety belt hanging rope is required to be used, screws can be screwed and fixed; when the length of the safety belt hanging rope between the two vertical rods is not enough, the screws can be loosened, the safety belt hanging rope is lengthened until the length is appropriate, and then the screws are fastened; U-shaped clamping grooves are formed in plate bodies of an upper pressing plate and a lower pressing plate and are used for accommodating the safety belt hanging rope, so that friction force is increased during fastening, and convenience is realized during loosening.

Background technology
In power system, isolating switch is one of modal equipment, be arranged on 2.5 meters of above base racks more, isolating switch needs periodic inspection to safeguard, in the past when isolating switch overhauls, maintenance worker is often suspended on safety belt on isolating switch support insulator or adopts low extension mode, its operation does not meet the pertinent regulations of the electric power safety working regulation > > of < < State Grid Corporation of China, very easily the person, equipment is damaged.In recent years, along with the arrival of transformer substation construction peak period, isolating switch is widely applied as the electric equipments of open type transformer station.For guaranteeing the safety in work progress, in the process that isolating switch is installed, do not allow safety belt to hang on insulator, in order to hang safety belt, often need to set up scaffold or use ladder truck, although can solve like this suspension problem of safety belt, but owing to setting up scaffold, often there is limitation in height in ladder truck, thereby the high problem that must solve that also becomes by problem of the low extension of high-rise working safety belt of the generation of following, simultaneously, owing to setting up scaffold etc., need to spend the more time, and current built transformer station mostly the duration tight, cost is low, when assurance is safe, how improving efficiency of construction is the current problem that needs solution with reducing cost input.
So be badly in need of now a kind of safe and convenient to use, make cheap and can adapt to when in use the isolating switch maintenance interval adjustable safety belt suspension device of all size isolating switch support.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of safe and convenient to use, make cheap and can adapt to when in use the isolating switch maintenance interval adjustable safety belt suspension device of all size isolating switch support.
For solving the problems of the technologies described above, technical solution adopted in the utility model is to provide a kind of isolating switch maintenance interval adjustable safety belt suspension device, comprise by upper clamp and lower clamp and through a pair of connecting bolt, install a pair of fixedly card being formed by connecting, and 2 vertical rods, it is characterized in that described 2 vertical rods are separately fixed on 2 lower clamps, and safety harness lanyard between two vertical rods, at least one vertical rod is provided with the length adjustable mechanism of safety belt lanyard.
Preferred described length adjustable mechanism, comprises top board, lower platen and the plural fastening bolt that passes upper lower platen, and lower platen is fixed on the top of vertical rod.
Preferably on the mating surface of top board and lower platen, be provided with U-shaped groove.
The preferred length direction of described U-shaped groove and the screw line of plural fastening bolt stagger and are parallel.
The effect that adopts technique scheme to obtain: the superior part of maximum of the utility model and other safety belt suspension devices is that for hanging the lanyard two ends of safety belt be adjustable, when will with time screw tightening can be fixed, when the length of the safety belt lanyard between two vertical rods is inadequate, screw can be unscrewed, lanyard is elongated, arrive applicable length afterwards again by fastened by screw, use very convenient, on the plate body of upper lower platen, be provided with U-shaped groove, safety belt lanyard is placed in one, in fastening, increased like this frictional force, also convenient in the time of loosening, safety band suspension arrangement adopts the mode of upper and lower double card plate to be fixed the channel-section steel on isolating switch frame, structure is firm, security insurance, and the distance between two upper and lower clamps can regulate the channel-section steel that is applicable to all size model.
