Abstract

A landing layer anti-clashing device of elevator comprises a landing layer movable swing link, a wire cable, a travel switch, a fire barrier. Each layer of the elevator stand is equipped with the landing layer movable swing link with one end movable and the other end equipped with a gripping head; one end of the wire cable is connected with a tension spring and together fixed on the top of the stand, the other end thereof passes through a slide bar and is connected with the tension spring and together fixed inside a control box; the gripping heads are fixed with the wire cable. The landing layer anti-clashing device of elevator in the utility model is characterized in that the wire cable runs through the whole elevator stand from top to bottom; each layer (as many as possible) can be arranged with the landing layer anti-clashing movable swing link; the landing layer with tens of layers controlled by one wire cable can be achieved. The utility model has simple structure and convenient operation with accuracy.

Description

Lift layer erosion control ejection device

The utility model relates to a kind of building ground elevator, especially a kind of lift layer erosion control ejection device.

At present, elevator remains the main mechanical that the building ground solves the vertical transport material, the elevator that use various places majority when stopping layer work is listened high-rise staffing control by the observation of operating personal eyes, ear, make operating personal very inconvenient like this, spirit is also nervous, it is very low to stop layer accuracy, error often occurs, and particularly high level, high-rise building are just difficult more.

The purpose of this utility model just provides a kind of simple in structure, both can accurately stop layer, can prevent the lift layer erosion control ejection device of rushing to summit again.

The purpose of this utility model be achieved in that lift layer erosion control ejection device comprise stop the layer a movable fork, steel cable, travel switch, the cutoff device, all be provided with on each layer of elevator support and stop the movable fork of layer, stopping movable fork one end of layer is movable end, the other end is provided with chuck, movable fork is that fulcrum is fixed on the elevator support with the middle part, steel cable one end and extension spring are fixedly connected at a top of the trellis, the other end is fixedly connected in the Ground Control case by slide bar and extension spring, chuck on the movable fork of each layer is all captiveed joint with steel cable, and control box Inner also establishes travel switch and cutoff device.

The maximum characteristics of lift layer erosion control ejection device of the present utility model are that steel cable runs through whole elevator support from top to bottom, do not appoint how many layers all can stop the movable fork of layer in each layer installation, reach the layer that stops of tens of layers of rope controls, it is simple in structure, accurate, easy to operate.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model structural representation;

Fig. 2 is local structure figure among Fig. 1.

Lift layer erosion control ejection device comprise stop the layer a movable fork 1, steel cable 5, travel switch 10, cutoff device 11, all be provided with on each layer of elevator support 2 and stop the movable fork 1 of layer, stopping movable fork 1 one end of layer is movable end, the other end is provided with chuck 4, stopping the movable fork of layer 1 is that fulcrum is fixed on the support 2 with the middle part, steel cable 5 one ends link to each other with extension spring 3, extension spring 3 is fixed on support 2 tops, the other end links to each other with slide bar 7, slide bar 7 is fixed in the Ground Control case 8 by extension spring 9 again, control box 8 Inner also are provided with travel switch 10, and cutoff device 11, the lug on the slide bar 7 are arranged between travel switch 10 and the cutoff device 11.

The principle of work of lift layer erosion control ejection device of the present utility model:

Steel cable 5 is subjected to extension spring 3, extension spring 9 effects at its two ends, place's tensioned state, the movable fork 1 of layer that stop of each layer links to each other with steel cable 5 through chuck 4, winch 6 drives elevator craning cage 13 upward movements, cage 13 moves along support 2 by the track adjusting wheel on it 12, when cage 13 is run into when stopping movable fork 1 movable end of layer, stopping the movable fork 1 of layer rotates around its fulcrum, it is provided with chuck end and moves downward and drive steel cable 5, slide bar 7 upward movements in this moment control box 8, lug on it makes travel switch 10 disconnect cage 13 stop motions; Malfunctioning as travel switch 10, cage 13 continues upward movement, and slide bar 7 is upward movement also, and at this moment, slide bar 7 makes cutoff device 11 cut off motor power rapidly.
