Description
Technical field：
It the utility model is related to a kind of ladder safety guard.
Background technology：
When press breaks down, related personnel needs to climb to that forcing press is walked on stage or cross rail top checks problem by ladder
Place, now it is ensured that forcing press is stopped, it is not activated by, to avoid the personal safety of maintainer.It is currently used
Safeguard measure is that safety cock is set on ladder, when safety cock is inserted in ladder frame hole, contacting travel switch, makes main motor
Operation condition is unsatisfactory for, so that it is guaranteed that equipment will not act when personnel overhaul, but needs maintainer to exist in this way
The placement of progress safety cock is needed before maintenance, if not inserting safety bar in ladder frame hole, people can still climb upwards,
The use of ladder can't be influenceed, if new person or unrelated person do not know about associative operation, potential safety hazard still be present.
Utility model content：
The utility model provides a kind of ladder safety guard, and it is reasonable in design, and maintainer is in ladder stand
The period of the day from 11 p.m. to 1 a.m can ensure that press is in halted state, avoid and maintainer is damaged, eliminate potential safety hazard, solve existing
There is problem present in technology.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of ladder safety guard, including one be hinged on door-plate on the side frame of ladder one, and one is provided with door-plate
The door lock of fixed door-plate, the door lock include the knob being movably arranged on door-plate, and the other end of the knob is stretched through door-plate
To the opposite side of door-plate, the card of a L-type is connected with the other end of knob, ladder is located at when card is threaded to horizontal level
The rear side of frame, travel switch is provided with ladder frame by installing mechanism, and the travel switch abuts against with door-plate.
The installing mechanism includes the welded gasket being arranged on ladder frame, passes through interior hexagonal cylindrical head spiral shell on welded gasket
Nail is provided with installing plate, is provided with travel switch on a mounting board.
The utility model uses said structure, and maintainer needs actively to disconnect travel switch in the ladder stand period of the day from 11 p.m. to 1 a.m, can
Ensure that press is in halted state, avoid and maintainer is damaged, eliminate potential safety hazard.
