Abstract
The utility model discloses a staircase forward position board overhauls anti -theft device, be fixed in on the staircase truss including forward position board and installation, it still includes balancing pole, safety switch and fixed plate to overhaul the anti -theft device, balancing pole left end portion upwards bends and extends to a vertical pole, fixed plate fixed connection on the staircase truss the balancing pole keeps left and all is equipped with a through -hole on tip position and the fixed plate, through through -hole swing joint, when the forward position board is closed on balancing pole and the fixed plate vertical pole upper end contacts just with forward position board diapire safety switch is located the balancing pole and leans on through -hole right side diapire under. This kind of staircase forward position board overhauls anti -theft device, overall structure is simple, and simple to operate can not crush safety switch by pressure, long service life, effectual realization sensitiveer than general spring switch effective, therefore safe moreover is safe overhauls and the theftproof function.
Description
technical field:
The utility model relates to the device on a kind of staircase, the maintenance anti-joyride device particularly on a kind of front plate for escalators.
background technology:
The front edge board of staircase is arranged on staircase and imports and exports position; play the effect of protection internal unit and carrying passenger; and in order to safety inspection and antitheft needs; the general front edge board that all can arrange on the front edge board of staircase overhauls anti-joyride device; but the jack sensitieness on general maintenance anti-joyride device is inadequate; and another is not easy to install by the version that switch directly pushed down by cover plate, and cover plate is easy to damage switch by pressure.
summary of the invention:
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, easy for installation and highly sensitive and not easily by the front plate for escalators maintenance anti-joyride device damaged by pressure.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of front plate for escalators maintenance anti-joyride device, comprise front edge board and be mounted on staircase and girder, described maintenance anti-joyride device also comprises trammel beam, safety switch and adapter plate, the upwards bending extend to a vertical bar of described trammel beam left part, described adapter plate is fixedly connected on staircase and girder, a through hole is equipped with on described trammel beam keeps left end position and adapter plate, described trammel beam and adapter plate are flexibly connected by through hole, when plate is closed ahead of the curve, described vertical bar upper end contacts with front edge board diapire, described safety switch is positioned at trammel beam by immediately below diapire on the right side of through hole.
As preferably, for making described trammel beam have better sensitivity in actual applications, be provided with a pouring weight in described trammel beam right part.
As preferably, for making described trammel beam and safety switch can have a better contact point, described trammel beam diapire arranges a boss, and described boss contacts with safety switch.
As preferably, up-and-down movement that can be milder when contacting with front edge board diapire for making the vertical bar upper end of described trammel beam, arranges a trundle in described vertical bar upper end.
As preferably, more fastening for making described adapter plate be connected with truss, between described adapter plate and staircase and girder, bolt is connected and fixed.
Compared with prior art, usefulness of the present utility model is: this front plate for escalators maintenance anti-joyride device, integral structure is simple, easy for installation, safety switch can not be damaged by pressure, long service life, and more effectively sensitiveer than general jack, thus can realize safety inspection and anti-theft feature safely and effectively.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is Facad structure schematic diagram of the present utility model
Fig. 2 is the Facad structure schematic diagram of part-structure partial enlargement of the present utility model
In figure: 1, front edge board 2, staircase and girder 3, trammel beam 4, safety switch 5, adapter plate
6, vertical bar 7, through hole 8, pouring weight 9, boss 10, trundle.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of front plate for escalators maintenance of the utility model anti-joyride device, as Fig. 1, shown in Fig. 2, comprise front edge board 1 and be mounted on staircase and girder 2, described maintenance anti-joyride device also comprises trammel beam 3, safety switch 4 and adapter plate 5, the upwards bending extend to a vertical bar 6 of described trammel beam 3 left part, described adapter plate 5 is fixedly connected on staircase and girder 2, preferably, be connected more fastening for making described adapter plate 5 with staircase and girder 2, between described adapter plate 5 and staircase and girder 2, bolt is connected and fixed, a through hole 7 is equipped with on described trammel beam 3 keeps left end position and adapter plate 5, described trammel beam 3 and adapter plate 5 are flexibly connected by through hole 7, preferably, for making described trammel beam 3, there is better sensitivity in actual applications, a pouring weight 8 is provided with in described trammel beam 3 right part, in addition for making described trammel beam 3 can have a better contact point with safety switch 4, described trammel beam 3 diapire arranges a boss 9, described boss 9 contacts with safety switch 4, in described vertical bar 6 upper end, one trundle 10 is set in addition again, thus up-and-down movement that can be milder when vertical bar 6 upper end of described trammel beam 3 is contacted with front edge board 1 diapire, when practical application, when front edge board 1 is closed, the trundle 10 of described vertical bar 6 upper end contacts with front edge board 1 diapire, described safety switch 4 is positioned at trammel beam 3 by immediately below the boss 9 on diapire on the right side of through hole 7, therefore, when front edge board 1 is opened, trundle 10 on described vertical bar 6 is not owing to having the effect of the pressure of front edge board 1, and due to lever principle, described vertical bar 6 rotates clockwise around the fulcrum on through hole 7, boss 9 on trammel beam 3 then rotates counterclockwise around through hole 7, then application force is applied to the safety switch 4 be positioned under it, thus triggering secure switch 4, control operation and the anti-joyride device of staircase, make staff's easy access repair and maintenance etc., when front edge board 1 is closed, described front edge board 1 diapire is pushed down the trundle 10 on vertical bar 6 and is made its counterclockwise movement until front edge board 1 is closed completely, then boss 9 clockwise movement on trammel beam 3 is driven, thus no longer oppress safety switch 4, safety switch 4 is made to recover initial state and be held open, thus control staircase and anti-joyride device normally run, therefore antitheft effect is also played, said apparatus integral structure is simple, easy for installation, safety switch can not be damaged by pressure, long service life, and it is more effectively sensitiveer than general jack, thus safety inspection and the anti-theft feature of staircase is realized safely and effectively.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
