Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As depicted in figs. 1 and 2, building hoist floor door of the present utility model, comprise doorframe 1, hingedly be installed on the door leaf 2 on doorframe 1 and be installed on the mechanical lock 3 on door leaf 2, also comprise and in the time that stop puts in place, triggered the safety lock 4 of opening by lift, safety lock 4 comprises fork 41 and is installed on the rotating shaft 42 on doorframe 1, one end of fork 41 is articulated with on doorframe 1, fork 41 is connected with rotating shaft 42 by toggle and can orders about the positive and negative rotation of rotating shaft 42 by reciprocally swinging, rotating shaft 42 is provided with the jam plate 43 that stops or allow door leaf 2 to open with the positive and negative rotation of rotating shaft 42, between doorframe 1 and fork 41, be provided with and force fork 41 to swing the coil tension spring 44 that makes jam plate 43 stop door leaf 2 to be opened, the other end of fork 41 is provided with roller 45, on lift, being provided with to coordinate with roller 45 forces fork 41 to swing the collision block that makes jam plate 43 allow door leaf 2 to open. in building hoist running, the floor door of each floor is all in closed condition, under the effect of coil tension spring 44, fork 41 orders about rotating shaft 42 and remains on and make jam plate 43 stop the rotational angle that door leaf 2 is opened, now jam plate 43 forms locking effect to door leaf 2, can prevent that floor internal staff from opening floor door from the outside, when lift leans against respective storey, contact with roller 45 by collision block and force fork 41 to swing towards the direction of compression coil tension spring 44, fork 41 orders about rotating shaft 42 by toggle and turns to and make jam plate 43 depart from the rotational angle of door leaf 2, now, opening mechanical lock 3 can open door leaf 2, lift leaves after floor, collision block departs from roller 45, the safety lock 4 locking door leaf 2 again that resets under the effect of coil tension spring 44.

This building hoist floor door is by arranging safety lock 4, thoroughly solve arbitrarily switch and cause people and thing easily to enter the potential safety hazard of building hoist operation passage of floor door, greatly improve the security performance of lift, ensure user of service's personal safety, and the control of safety lock 4 is controlled automatically by lift, reduce building hoist driver's labour intensity.

Above-mentioned toggle comprises crank 46 and connecting rod 47, and crank 46 is fixed in one end of rotating shaft 42, and the middle part of one end of connecting rod 47 and fork 41 is hinged, and the other end of connecting rod 47 and crank 46 are hinged.

In the present embodiment, rotating shaft 42 is positioned at the top of doorframe 1 and is parallel to doorframe 1 arranges, it can be arranged on the scaffold on doorframe 1, easy to install. Two fans are installed in doorframe 1 and are the door leaf 2 that the form of splitting is installed, wherein a door leaf 2 is provided with and stops down in off position the baffle plate 5 that another door leaf 2 is opened, in rotating shaft 42, be only provided with a jam plate 43 for stoping or allow this door leaf 2 that is provided with baffle plate 5 to be opened, 4 of safety locks need to pin Yishanmen and two fan door leafs 2 all can be pinned, simple and practical.

In the present embodiment, as shown in Figure 3, mechanical lock 3 comprises the keeper 31 that slides and arrange, building hoist floor door also comprises induction keeper 31 sliding positions and in the time that keeper 31 is opened door leaf 2, cuts off the travel switch 6 of lift power supply, the trip switch 6 is connected with the control device of lift power supply, in the time of keeper 31 sliding latch door leaf 2, its end and travel switch 6 offset, and travel switch 6 is responded to keeper 31 and cut off lift power supply by control device; In the time of keeper 31 sliding opening door leaf 2, its end is away from travel switch 6, and travel switch 6 is responded to keeper 31 and departed from and open lift power supply by control device, and lift can normally be worked. By travel switch 6 is set; form double protection; after once keeper 31 pulls open; lift power supply is cut off immediately; therefore; all floor doors must put in place by Close All, and building hoist can move, and have avoided building hoist in the time moving, to have floor door open and cause people and thing all can enter building hoist operation passage and cause safety problem.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment. For those skilled in the art, do not departing from the improvement that obtains under the utility model technical conceive prerequisite and conversion also should be considered as protection domain of the present utility model.
