Abstract
The invention discloses an anti-theft device for escalator leading-edge plate overhauling. The anti-theft device for escalator leading-edge plate overhauling comprises a leading-edge plate and fixed to an escalator truss. The anti-theft overhauling device further comprises a balance rod, a safety switch and a fixing plate. The left end of the balance rod is bent upwards and stretches to form a vertical rod. The fixing plate is fixedly connected to the escalator truss. The portion, close to the left end, of the balance rod and the fixing plate are provided with two through holes respectively. The balance rod and the fixing plate are movably connected with each other through the through holes. The upper end of the vertical rod makes contact with the bottom wall of the leading-edge plate when the leading-edge plate is closed. The safety switch is located under the position, close to the bottom wall of the right side of the through hole, of the balance rod. The anti-theft device for escalator leading-edge plate overhauling is simple in overall structure and convenient to mount, and the safety switch cannot be pressed and damaged and is long in service life and more sensitive and effective compared with general spring switches, so that safe overhauling and the anti-theft function can be achieved safely and effectively.
Description
technical field:
the present invention 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 problem to be solved in the present invention 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 present invention is achieved by 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 invention 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 present invention is further described:
Fig. 1 is Facad structure schematic diagram of the present invention
Fig. 2 is the Facad structure schematic diagram of part-structure partial enlargement of the present invention
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:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of front plate for escalators maintenance of the present invention 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 invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
