Description
Technical field
The utility model relates to a kind of work high above the ground anti-falling device, belongs to work high above the ground personnel fall arrest lifesaving safety guard class manufacturing technology field.
Background technology
In industries such as electric power, telecommunications, shaft tower carried out work high above the ground about the staff often wanted, owing to there is not reliable falling-proof safety device, safety code can't be implemented, and often caused the accident of ascend operation to take place.State Grid's industry regulation, ascend operation must have the protection of safety belt, plays the effect that prevents that the high-altitude from falling.But the fall arrest about ascending a height, in the moving process such as transposition exists serious safety problem; present existing protective device complex structure, screw are fixed; and be to constitute, be unfavorable for one-handed performance and transfer, bring certain trouble to the operator by two or more independent assemblies.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of easy to operate, integrated formation and the work high above the ground anti-falling device of being convenient to singlehanded folding operation and shifting up to specification are provided.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of work high above the ground anti-falling device, it comprises the big impeller and the lobula plate of flexible connection, is provided with the concave through grooves of passing steel strand wires or steel wire rope on big impeller; Be provided with rocking arm between big impeller and lobula plate; rocking arm is installed on the swing arm sleeve, and swing arm sleeve one end passes lobula plate and is connected with handle apparatus, and lock shaft is installed in swing arm sleeve; be provided with the through hole that matches with lock shaft on the impeller greatly, lock shaft passes through hole and matches with locking plate device on the impeller greatly.
Described big impeller is for being made into integration, and lobula plate is hinged with big impeller by the lobula plate axle.
Described locking plate device comprises locking plate, and locking plate is riveted on the big impeller by the locking plate axle, and is connected with the locking plate spring is coaxial with resetting.
One end of described rocking arm extend in the groove of big impeller.
Described handle apparatus comprises handle, and handle and lock shaft riveted joint on lobula plate, are provided with handle spring between handle and swing arm sleeve by the swing arm sleeve pin joint.
The utility model comprises large and small impeller, rocking arm, handle and lock shaft, locking plate; Wherein, big impeller is provided with the concave through grooves that can pass steel strand wires (or steel wire rope), lobula plate is arranged on the groove mouth place of big impeller and is connected on the big impeller, the handle that a big impeller folding of control is arranged in the side of lobula plate, be connected with rocking arm on the wall of lobula plate, an end of rocking arm extend in the groove of big impeller.Handle and lock shaft pass through the swing arm sleeve pin joint on lobula plate, and opening with reset position at handle has lock shaft and locking plate to realize the locking location by the locking plate spring reset.Lock shaft passed through hole in the big impeller after handle resetted, and its recess one end matches with the recess that fastens back locking plate avris, pins big impeller.
The utility model should be assemblied in the steel strand wires (or steel wire rope) of vertical direction and go up use [if be assemblied in the upward use of steel strand wires (or steel wire rope) of inclination, be no more than 45 degree with the vertical direction angle], connect with the human body safety belt by safety rope, has directionality during assembling, the right hand is held catching device (microcephaly is the top towards a side) during operation, tiger is upwards withstood rocking arm, forefinger and middle finger are clamped handle and are protracted and fasten big lobula plate hinge axis, push locking plate open with thumb, exert oneself jack-up handle of forefinger middle finger makes lock shaft withdraw from through hole in the big impeller, open big impeller, steel strand wires (or steel wire rope) are through in the big impeller concave through grooves, fasten big lobula plate then, handle and lock shaft reset under the effect of handle spring, lock shaft passes big impeller and locking plate locking location, and the locking plate recess is at this moment by locking plate spring reset and the interlock mutually of lock shaft recess, and lock shaft is located.
During normal shaft tower up and down, on steel strand wires (or steel wire rope), anti-falling device gravity overcomes the elastic force of spring for rocker shaft, and anti-falling device can slide by easy on and off; When human body falls, under spring for rocker shaft elastic force and the acting in conjunction of rocking arm gravity, make the rocking arm locking, end the human body fall, guarantee personal safety.
When anti-falling device need be when steel strand wires (or steel wire rope) break away from, the right hand is held catching device, tiger is upwards withstood rocking arm, forefinger and middle finger are clamped handle and are protracted and fasten big lobula plate hinge axis, push locking plate open with thumb, exert oneself jack-up handle of forefinger middle finger makes lock shaft withdraw from through hole in the big impeller, opens big impeller, and big impeller is broken away from from steel strand wires (or steel wire rope).
The beneficial effects of the utility model are: simple in structure, safe and reliable, satisfy the one-handed performance needs fully, and can effectively prevent the human body fall, guarantee personal safety.
