Abstract
The utility model relates to a linkage emergency door for hoisting machinery. Rails are erected at two ends of the emergency door; limiting inductors are arranged on the rails; guard railings are arranged on the rails at the two ends; pulleys are arranged at the upper parts of the rails; two ends of steel wire ropes on the fixed pulleys are connected with counterbalances and the guard railings respectively. After the adoption of the linkage emergency door, the limiting inductors can be used for controlling the starting of a hoister or a dual-purpose elevator, for example, the limiting inductors of the emergency doors on all storeys of a building under construction are connected in series to realize mutual linkage, so that when one emergency door is not thoroughly closed, the material hoister and the dual-purpose elevator cannot hoist, and the personal safety when an operator enters in or goes out of the material hoister and the dual-purpose elevator is completely ensured.
Description
Technical field
The utility model relates to a kind of elevator machinery interlock safety door.
Background technology
At present, the elevator machinery that common buildings engineering is used is material elevator and the dual-purpose elevator of people's goods, and the building materials on building ground all must carry out vertical transport by material elevator or the dual-purpose elevator of people's goods.Therefore, material elevator or the dual-purpose elevator of people's goods are that charging and discharging and workmen pass in and out the highest part of frequency, but turnover and the lifting of material elevator or the dual-purpose elevator of people's goods lack safety device, if in the time that operating personnel does not leave material elevator or the dual-purpose elevator of people's goods, operating personal just starts gig or elevator, and casualty accident easily occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of elevator machinery interlock safety door that can prevent safety misadventure.
The technical scheme that the utility model is taked is: interlock safety door for a kind of elevator machinery, it is characterized in that its two ends setting has track, track is provided with limit induction device, guard rail is built up on the track at two ends, portion is provided with pulley in orbit, and the two ends of the steel cable on fixed pulley are connected with guard rail with balance block respectively.
Adopt the utility model, can be by the startup of limit induction device control gig or the dual-purpose elevator of people's goods, as the limit induction device of each layer of safety door building building is connected, just interlock mutually, as long as there is a fan safety door not shut, material elevator and the dual-purpose elevator of people's goods just can not lift by crane, and guarantee that operating personnel passes in and out the life safety of material elevator and the dual-purpose elevator of people's goods completely.
Brief description of the drawings
Fig. 1 is front elevational schematic of the present utility model.
Fig. 2 is schematic side view of the present utility model.
In figure, sequence number represents: fixed pulley 1, limit induction device 2, balance block 3, track 4, guard rail 5 and steel rope 6.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
With reference to Fig. 1, this elevator machinery is erect and is had track 4 with the two ends of interlock safety door, and track 4 is provided with limit induction device 2, and guard rail 5 is built up on the track 4 at two ends, be provided with fixed pulley 1 on track 4 tops, the two ends of the steel cable 6 on fixed pulley 1 are connected with guard rail 5 with balance block 3 respectively.When use, in the time that people need to enter material elevator, only need to lift guard rail 5 gently, under the application force of balance block 3, guard rail 5 rises along track 4, and now limit induction device 2 disconnects, and material elevator can not start; After people enters, decontrol guard rail 5, guard rail 5 declines along track 4, and balance block 3 rises and makes limit induction device 2 closures, now, can start material elevator.In order to ensure better safety, the limit induction device of each layer of safety door building building can be connected, just interlock mutually, as long as have a fan safety door not shut material elevator and the dual-purpose elevator of people's goods just can not lift by crane, guarantee that operating personnel passes in and out the life safety of material elevator and the dual-purpose elevator of people's goods completely.
