Description

Dumb waiter electromechanical door lock
Technical field
The utility model relates to a kind of dumb waiter, and particularly a kind of electromechanical door lock of dumb waiter, belong to the elevator technology field.
Background technology
At present, the dumb waiter door lock can be divided into two types: a class is not to be with the door lock of elevator of electric safety device assembly, and the locking of layer door relies on spring produce and keep fully, and spring failure car does not arrive at a station, and layer door can be opened.The device that confirms layer door locking is comprised of the limit switch that is arranged on the sedan-chair top, the hitting bow that is arranged on layer door, and car arrives at a station, and door lock hits bow and roller collision, opens door lock, opens layer door; Car is leaving from station, and a layer door closed, and layer hits bow and runs into limit switch confirmation layer door closure.This type of sundry elevator door lock structure is too simple, dangerous, and also needs to increase a set of parts, so this type of door lock is seldom used.Another kind of door lock of elevator carries the electric safety device assembly, increases an electric safety device contact adapter plate on layer door-plate, guarantees that car arrives at a station just can open layer door; But the locking of such elevator door is still and relies on spring to produce fully and keep, and spring failure car does not arrive at a station, layer door can be opened.This type of sundry elevator door lock structure comparison one class improves to some extent, but still is to guarantee safety.
The utility model content
The purpose of this utility model is, a kind of dumb waiter electromechanical door lock is provided.The utility model has improved the safety that dumb waiter is used, and the utility model is simple in structure, easy for installation, but large-scale mass production.
The technical solution of the utility model: a kind of dumb waiter electromechanical door lock, comprise the substrate be fixed on elevator door, substrate is provided with a stay bearing plate, is equipped with one in stay bearing plate and hits plate, and an end that hits plate is provided with roller, and the other end that hits plate is provided with the weight plate; A locking bar is fixed in described centre of hitting plate; Described hitting between plate and stay bearing plate also is provided with a spring.
In above-mentioned dumb waiter electromechanical door lock, the top of described substrate is provided with electric safety device.
In aforesaid dumb waiter electromechanical door lock, the described sidepiece that hits plate also offers a double polarizing keys.
In aforesaid dumb waiter electromechanical door lock, described inboard of hitting plate is provided with a pilot bar, is arranged with spring in pilot bar, and described stay bearing plate is provided with the groove agreed with mutually with pilot bar.
Compared with prior art, the utility model is provided with roller at an end that hits plate, and the other end that hits plate is provided with heavily beats plate, hits between plate and stay bearing plate and is provided with spring, hits the middle locking bar of fixing of plate; When car does not arrive at a station, hit plate perk under the elasticity of spring, locking bar can not opened the layer lock in layer door, the utility model is under the spring failure state, heavily beating the plate gravitate equally can drive and hit the plate perk, guarantee under the spring failure state, hit the layer lock that locking bar rotating opening layer door yet can not replied and make to plate, improved the safety of using.In addition, the utility model is provided with electric safety device above substrate, and when electric safety device contacts with the electrical contact coordinated with it of the layer door position that is arranged on hoistway, the elevator door of elevator just can be opened, and has improved further the safety of elevator.As further preferably, the described sidepiece that hits plate also offers double polarizing keys, and double polarizing keys re-packs and is meshed with a switch that is arranged on layer door position, makes the electrical contact of switch on re-packing stablize and contact with electric safety device of the present utility model.Further, the inboard of hitting plate is provided with a pilot bar, and stay bearing plate is provided with the groove agreed with mutually with pilot bar, after spring housing is located at pilot bar, and can stage clip when hitting the plate rotation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model and switch re-pack and assemble.
Being labeled as in accompanying drawing: the 1-substrate, the 2-stay bearing plate, 3-hits plate, the 4-roller, 5-heavily beats plate, 6-locking bar, 7-spring, 8-electric safety device, 9-double polarizing keys, 10-pilot bar, 11-groove.
The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment: a kind of dumb waiter electromechanical door lock, form as shown in Figure 1, comprise the substrate 1 be fixed on elevator door, substrate can be fixed on the side laminate of elevator door, substrate 1 is provided with a stay bearing plate 2, offer a through hole in the middle of stay bearing plate, be equipped with one in stay bearing plate 2 and hit plate 3, an end that hits plate 3 is provided with roller 4, the other end that hits plate 3 is provided with weight plate 5, heavily beat plate sagging under Action of Gravity Field, hit plate and rotate perk, make locking bar 6 keep closed condition; A locking bar 6 is fixed in described centre of hitting plate 3; Described hitting between plate 3 and stay bearing plate 2 also is provided with a spring 7, hits plate during normality and also rotate perk under the elasticity of spring.The top of described substrate 1 is provided with electric safety device 8, as shown in Figure 2, the electrical contact 13 that the electric safety device of substrate 1 and the switch that is arranged on elevator hoistways layer door position re-pack on 12 coordinates, when electric safety device arrives the electrical contact position, one of them condition of opening as elevator door, play the assurance elevator door and only open when arriving at a station, improve safety.The described sidepiece that hits plate 3 also offers a double polarizing keys 9, and when car arrives at a station, the engagement that re-packs of double polarizing keys and switch, guarantee that electric safety device can stablize and contact with electrical contact, further improves safety.Described inboard of hitting plate 3 is provided with a pilot bar 10, is arranged with spring 7 in pilot bar 10, and described stay bearing plate 2 is provided with the groove 11 agreed with mutually with pilot bar 10, and the spring stage clip has been avoided in the design of this structure.
Principle of work: at spring force with heavily beat under the double effect of plate gravity, locking bar rotates perk, make elevator door keep Locked under state, two self-locking states have guaranteed that the utility model still can guarantee the elevator door locking when spring failure, have improved safety.When car arrives at a station, electric safety device contacts with the electrical contact on the switch that is arranged on hoistway layer door position re-packs; Roller contacts with the bow that hits of hoistway layer door position simultaneously, drives to hit the plate rotation and then drive locking bar to rotate, and opens a layer door lock, and the car door of lift car just can be opened thus.
