Abstract
The present invention relates to a kind of staircase back plate prevent lifting safety device, belong to elevator safety field.It includes back plate, baffle plate it is provided with below back plate, a guide post it is fixedly connected with on baffle plate, guide post middle-end clamping one pressing plate, the spring assembly of set upspring baffle plate and pressing plate on the guide bar it is provided with below pressing plate, pressing plate lateral mechanical connects a safety switch, and safety switch is directly connected to staircase and controls power supply.Baffle plate can be pushed down when back plate is covered during normal mounting, baffle plate by downward pressure transmission to guide post, the safety switch that guide post band dynamic pressure plate connects, safety switch is made to close, staircase is properly functioning, and once back plate is lifted, and pressing plate will be made under the influence of spring assembly elasticity to lift, safety switch mechanical type disconnects, and can effectively prevent the generation of fortuitous event.Usefulness of the present invention is: instead of the pure electric-type back plate not being inconsistent Standard commonly used and prevents lifting safety device.Utilize spring to apply active force, make switch contact realize machinery forcibly and disconnect.Its compact structure, it is simple to installation and debugging, can effectively prevent the generation of fortuitous event.
Description
Technical field:
The present invention relates to a kind of staircase back plate prevent lifting safety device, belong to elevator safety field.
Background technology:
" 5.12.1.2.2 safety switch " regulation in " safety standard installed by GB16899-2011 escalator and moving sidewalk "
" action of safety switch should make its contact point machinery forcibly disconnect, and even two contact welds the most also should be mechanical forcibly
Disconnect." nowadays the back plate of escalator is anti-lifts safety device commonly used safety switch contact and directly connect with staircase back plate
Touching, the action of switch contact relies on automatically reseting of switch itself, does not use frame for movement forcibly.This commonly used
Device does not meets new national standard requirement.
Summary of the invention:
In order to solve above technical problem, a kind of staircase back plate that the present invention relates to is anti-lifts safety device.Including back plate, back plate
Lower section is provided with baffle plate, baffle plate is fixedly connected with a guide post, guide post middle-end clamping one pressing plate, is provided with to be enclosed within and leads below pressing plate
The spring assembly of upspring baffle plate and pressing plate on bar, pressing plate lateral mechanical connects a safety switch, and safety switch directly connects
Connect staircase and control power supply.
Further, spring assembly is in compressive state when back plate is covered, and is in open configuration when back plate is lifted, permissible
Utilize the elasticity of spring to control safety switch, it is ensured that safety.
Further, pressing plate bolt fixing with guide post employing is fixing to be connected, and can effectively transmit the state letter of back plate
Breath, improves the response speed of safety switch.
Compared with prior art, usefulness of the present invention is: instead of the pure electricity not being inconsistent Standard commonly used
Formula back plate is anti-lifts safety device.Utilize spring to apply active force, make switch contact realize machinery forcibly and disconnect.Its structure is little
Ingeniously, it is simple to installation and debugging, the generation of fortuitous event can effectively be prevented.
Accompanying drawing illustrates:
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is that staircase back plate is anti-lifts safety device side block diagram；
During Fig. 2, staircase back plate is anti-lifts safety device lifting status front view.
In figure: 1, back plate；2, baffle plate；3, guide post；4, pressing plate；5, spring assembly；6, safety switch；7, power supply is controlled；
8, fixing bolt.
Detailed description of the invention:
As depicted in figs. 1 and 2: a kind of staircase back plate that the present invention relates to is anti-lifts safety device, including rear 1 plate, below back plate 1
It is provided with baffle plate 2, baffle plate 2 is fixedly connected with a guide post 3, guide post 3 middle-end clamping one pressing plate 4, is provided with below pressing plate 4 and is enclosed within
The spring assembly 5 of upspring baffle plate 2 and pressing plate 4 on guide post 3, pressing plate 4 lateral mechanical connects a safety switch 6, safety open
Close 6 and be directly connected to staircase control power supply 7.Spring assembly 5 is in compressive state when back plate 1 covers, and back plate 1 is in when lifting opens
Open state, it is possible to use the elasticity of spring controls safety switch 6, it is ensured that safety.Pressing plate 4 and guide post 3 use fixing bolt 8
Fixing connection, can effectively transmit the status information of back plate, improves the response speed of safety switch.
Can push down baffle plate 2 when back plate 1 covers during normal mounting, downward pressure transmission to guide post 3, is guided by baffle plate 2
The safety switch 6 that bar band dynamic pressure plate 4 connects, makes safety switch close, and staircase is properly functioning, and once back plate is lifted, in groups of springs
Pressing plate 4 will be made to lift under the influence of part 5 elasticity, safety switch 6 mechanical type disconnects, and can effectively prevent the generation of fortuitous event.
It is emphasized that: be the most only introduction and the description of the occupation mode of the present invention, not the present invention made any
Pro forma restriction, any simple modification that above example is made by every technical spirit according to the present invention, equivalent variations
With modification, all still fall within the range of technical solution of the present invention.
