Description

Fall protection device for working at height

Technical field

The utility model belongs to the work high above the ground security tool, mainly proposes a kind of fall protection device for working at height, the safety guarantee when being used for electric power tower or other work high above the ground.

Background technology

The human body safety belt connected with anti-disengagement between the pylon when fall protection device for working at height was used for work high above the ground.Present stage, the measure of work high above the ground fall arrest is: human body lap belt one end connects with pylon with the safety button, and needs overlapped once again when the position that moves up and down exceeded certain distance.The problem that this kind manipulated mode is: there is unsafe factor in inconvenient operation, as meets accident effectively to stop and fall.

Summary of the invention

For addressing the above problem, the purpose of this utility model is to propose a kind of fall protection device for working at height.

The utility model is to finish the technical scheme that its invention task takes to be: a kind of fall protection device for working at height mainly comprises T shape track and sliding seat; Described T shape track is arranged on the electric power tower or other facility of required operation; Described sliding seat combines with T shape track and can move up and down along T shape track; Described sliding seat has makes it snap in the T-slot of T shape track; Described sliding seat has movable pressing board and movable pressing board is articulated and connected by jointed shaft and sliding seat, is provided with in the sliding seat to stretch into the check lock lever piece of in the sliding seat T-slot the relative T shape of sliding seat track being locked under the movable pressing board effect; Be provided with second stage clip that makes movable pressing board under its elastic reaction, rotate and act on the check lock lever piece around jointed shaft; Be provided with first stage clip that check lock lever piece withdrawal sliding seat is resetted in the sliding seat.

The cell wall of described sliding seat T-slot is provided with ratio wheel, directive wheel and directional wheel, in order to guarantee that sliding seat is at not stall when T type track moves, no deflection, no clamping stagnation.

On described movable pressing board, has the irregularly-shaped hole that connects safety rope and actuating movable pressing board.

Use of the present utility model is: the snap ring of safety rope one end is connected with irregularly-shaped hole on the sliding seat movable pressing board, sliding seat is combined with T type track from T type track bottom by T-slot, the operative employee is when the electric power tower makes progress, under the effect that safety rope upwards lifts, movable pressing board rotates counterclockwise and makes pairing stage clip compression around jointed shaft, the check lock lever piece the effect lower front end of corresponding stage clip be positioned at sliding seat, sliding seat moves up with safety rope along T type track; Slip up when falling downwards the operative employee, the movable pressing board of sliding seat clockwise rotates (pairing stage clip release) around jointed shaft and acts on the check lock lever piece, check lock lever piece front end is stretched in the T-slot of sliding seat the locking of the relative T shape of sliding seat track, play the safety effect of fall arrest.

A kind of fall protection device for working at height that the utility model proposes, its reasonable in design, guaranteed the safe and reliable of work high above the ground, used operation very convenient again simultaneously, for work high above the ground personnel especially high-tension line installation and maintenance provide safe and reliable aid.
