In order to overcome prior art not enough, it is proposed that a kind of device preventing elevator accidental movement, it brakes effect
The best, reliability is high.
(2) technical scheme
This utility model is achieved through the following technical solutions: the utility model proposes one and prevents elevator unexpected
The device of movement, including be fixed on car anti-fall basic blocks group and anti-liter of basic blocks group, anti-fall base
Plinth block group and anti-liter of basic blocks group all include two basic blocks being symmetricly set in cage guide both sides, described
Two basic blocks opposite faces of anti-fall basic blocks group tilt in herringbone, described two bases of anti-liter of basic blocks group
Block opposite face tilts in splayed, is all fixedly installed one and detects with car door on arbitrary basic blocks opposite face
The solenoid of switch electrical connection, one end of solenoid is connected by spring a wedge, described wedge shape
Block is being provided with in slide block and basic blocks slide block is being provided with slideway, wedge at basic blocks contact surface
It is being provided with brake(-holder) block at cage guide contact surface.
Preferably, described wedge be can with the solenoid magnetic absorption after energising to draw magnetic material made
Form, described in draw magnetic material be Magnet or ferroalloy.
(3) beneficial effect
This utility model, relative to prior art, has the advantages that
A kind of device preventing elevator accidental movement that this utility model is mentioned, it is by car door detection switch
Whether control solenoid is energized and has magnetic, and when car door is opened, solenoid power-off, wedge exists
It is squeezed on cage guide under spring effect, plays the effect of braking, whenever faint accidental movement occurs in car
Time, wedge can extrude the nearest, and braking effect can be the best, and reliability is high.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
1-anti-fall basic blocks group；Anti-liter of basic blocks group of 2-；3-cage guide；4-solenoid；5-spring；

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
A kind of device preventing elevator accidental movement as shown in Figure 1, including be fixed on car anti-fall
Basic blocks group 1 and anti-liter of basic blocks group 2, anti-fall basic blocks group 1 and anti-liter of basic blocks group 2 all include two
The individual basic blocks 11 being symmetricly set in cage guide 3 both sides, described 1 two basic blocks 11 of anti-fall basic blocks group
Opposite face tilts in herringbone, and 2 two basic blocks 11 opposite faces of described anti-liter of basic blocks group tilt in eight words
Shape, is all fixedly installed an electricity electrically connected with car door detection switch 9 on arbitrary basic blocks 11 opposite face
Magnetic coil 4, one end of solenoid 4 by spring 5 connect have a wedge 6, described wedge 6 with
It is provided with at basic blocks 11 contact surface in slide block 7 and basic blocks 11 and slide block 7 is provided with slideway 8, wedge
Shape block 6 is being provided with brake(-holder) block 10 at cage guide 3 contact surface.
Wherein, described wedge 6 for can with energising after solenoid 4 magnetic absorption draw magnetic material institute
System forms, described in draw magnetic material be Magnet or ferroalloy.
A kind of device preventing elevator accidental movement that this utility model is mentioned, it works as sedan-chair when specifically used
When railway carriage or compartment door is closed, car door detection switch 9 detects shutdown signal, controls solenoid 4 and is energized, utilizes
Electromagnetic principle, solenoid 4 produces magnetic field, it is possible to wedge 6 produces magnetic adsorptive power, anti-fall basis
Wedge 6 in block group 1 is moved up in slideway 8 by slide block 7, the wedge in anti-liter of basic blocks group 2
Shape block 6 is moved down in slideway 8 by slide block 7, and wedge 6 deviates cage guide 3, and elevator is normally transported
