Abstract
The invention relates to a spacing-adjustable safety belt hanging device for disconnecting switch overhaul, in particular to the technical field of power construction safety protection tools. The spacing-adjustable safety belt hanging device comprises a pair of fixed clamping bodies which are formed by connecting upper clamping plates and lower clamping plates through a pair of connecting bolts in a penetrating mode and two uprights. The two uprights are fixed onto the two lower clamping plates respectively, a safety belt hanging rope is connected between the two uprights and a length adjustable mechanism of the safety belt hanging rope is arranged on at least one upright. Compared with other safety belt hanging devices, the spacing-adjustable safety belt hanging device has the greatest advantage that the two ends of the hanging rope used for hanging a safety belt are adjustable. When the spacing-adjustable safety belt hanging device needs to be used, screws can be screwed down and fixed. When the length of the safety belt hanging rope between the two uprights is not enough, the screws can be unscrewed to draw out the safety belt hanging rope, and after the length becomes appropriate, the screws are fastened again. In addition, U-shaped clamping grooves are formed in a plate body of an upper pressing plate and a plate body of a lower pressing plate, the safety belt hanging rope is placed inside the U-shaped clamping grooves, therefore, friction force is increased during fastening and unscrewing can also be more convenient.
Description
Technical field
The present invention relates to power construction security protection technical field of tools.
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, and its operation does not meet the pertinent regulations of " State Grid Corporation of China's electric power safety working regulation ", 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.
Summary of the invention
The technical problem to be solved in the present invention 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, the technical solution used in the present invention 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 present invention 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.
