Description

The dumb waiter vertical centering control divides automatically-controlled door

The utility model relates to a kind of improvement of dumb waiter.

Existing dumb waiter has only Room door, does not have automatic car door, after promptly goods is put into elevator, external door is closed goods is promoted or the transportation that descends, and does not block in elevator owing to goods like this, and goods drops out easily external door blocked and causes danger during transportation.

The utility model purpose provides a kind of dumb waiter car and is provided with vertical centering control and divides automatically-controlled door.

The utility model is made up of motor, drive link, pulley bracket and pulley, door, motor links to each other with connecting rod by retarder, connecting rod links to each other with swing arm, the other end of swing arm links to each other with the swing arm wheel, the swing arm wheel is positioned at the chute of a last square slide, an end that is positioned at the interlock rope (chain) on the fixed pulley with link to each other to the doorstep, the other end links to each other with the connecting plate on top, Xiamen; The motor reducer output shaft is provided with bob-weight.

The utlity model has characteristics such as rational in infrastructure, practical, that performance is safe and reliable.

Accompanying drawing 1 is looked the local structure scheme drawing for the utility model master.

Accompanying drawing 2 is the utility model birds-eye view.

Accompanying drawing 3 is the utility model perspective view.

Below in conjunction with accompanying drawing the utility model is further described, the output shaft of motor 1 of the present utility model is provided with retarder, retarder links to each other with swing arm 3 by three grades of connecting rods 2, the other end of swing arm links to each other with swing arm wheel 4, the swing arm wheel is positioned at a chute of last square slide 5, an end that is positioned at the interlock rope (chain) 7 on the fixed pulley 6 with 8 link to each other to the doorstep, the other end links to each other with the connecting plate 10 on 9 tops, Xiamen, its principle of work is such, when motor rotates, retarder pulling link work, like this, connecting rod drives swing arm and does movement in a curve, moves in the chute in the slide plate of swing arm wheel above door, the drive gate opens or closes, and drives Room door synchro switch by the interlinked mechanism on the car simultaneously.Since an interlock rope on the fixed pulley or an end of chain with link to each other to the doorstep, the other end links to each other with the connecting plate on top, Xiamen, slide in the chute of the slide plate of swing arm wheel above door, the drive slide plate rises, rise to the doorstep simultaneously, the Xiamen descends, Automatic door of elevator is opened shoulder, when automatically-controlled door need be closed, only need Push switch provide out code, automatically-controlled door can be closed, and closes tighter or opens more abundant in order to make automatically-controlled door, the motor reducer output shaft is provided with bob-weight 11, automatically-controlled door of the present utility model can adopt retractable door, also can adopt closed iron plate door, and this dumb waiter vertical centering control divides automatically-controlled door easy to install and use, performance is safe and reliable, is applicable to various dumb waiters.
