Abstract
The utility model discloses an elevator car toeguard device that stretches out and draws back, including the car, the roof beam structure front end is provided with collapsible flexible protection sole and fix the support frame under the car, but can the vertical gliding mobile location groove of installing in the fix the support frame, but a plurality of slidable movable bearing seats are installed to the mobile location inslot, and wherein the equal horizontally connect of each movable bearing seat has a portable support frame, the protection sole concatenates with portable support frame top -down in proper order. This device structure can be contract when moving to the pit automatically, but same automatic re -setting when leaving for structural stability improves greatly, and the device life be protected.
Description
Technical field
The utility model relates to elevators field, is specially a kind of lift car and stretches foot protecting plate device.
Background technology
Along with land resources worsening shortages, various building develops into trend to high-altitude, and the elevator requisite transportation means that is skyscraper, and due to the particularity of elevator working environment, the safety of elevator is most important.
In many elevator safety fail-safe structures, the Main Function of lift car toeguard prevents passenger from falling from the gap between car and landing sill higher than during stop ground on car ground.Specify according to GB/T21739-2008 " home lift manufacture and installation specification ": under each car sill, all should toeguard be installed, its width should equal the whole span width of corresponding landing entrance, the vertical dimension of toeguard should not be less than 0.75m, and this height is measured from car sill.When elevator is in maintenance or rescue state, when car bottom plane exceeds floor level, existing toe guard of elevator car can not shrink automatically when running to pit, can not automatically reset, cause device damage when leaving, and toeguard is short for service life.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of lift car and to stretch foot protecting plate device.
The utility model solves the technical scheme that its technical matters adopts:
A kind of lift car stretches foot protecting plate device; comprise car; described car frame plank frame front end is provided with protection sole and the fixing support rack of foldable telescopic; that can vertically slide in described fixing support rack is provided with removable positioning groove; some slidably movable axis bearings are installed in described removable positioning groove; wherein the equal level connection joint of each movable axis bearing has removable bracing frame, and described protection sole is connected in series from top to bottom successively with removable bracing frame.
As the improvement of technique scheme; movable connecting panel is provided with above each movable axis bearing corresponding in described removable positioning groove; and each removable supporting framing front end upper and lower sides is provided with living hinge; wherein; be positioned at movable connecting panel to be topmost connected with the upside living hinge of protection sole and the removable bracing frame in below thereof respectively by cable, adjacent removable bracing frame is connected by the two inner side living hinge and movable connecting panel.
As the improvement of technique scheme, when ascending for elevator, described removable positioning groove, arrange movable axis bearing in the inner and removable bracing frame all because gravity naturally droops, device is in extended configuration; When elevator comes downwards to bottom, described removable positioning groove contact pit is also up relative to car, and described living hinge starts hinge and movable connecting panel starts to shrink, and described movable axis bearing rises mobile relative to car, this timer is in contraction state.
As the improvement of technique scheme, described cage bottom is provided with protective case, and removable positioning groove cover can be put when device is in contraction state and form protective action in the inner by it.
The beneficial effect that the utility model brings has:
This device is reaching elevator safety requirement of shelter---and prevent passenger while car ground is higher than danger of falling from the gap between car and landing sill during stop ground, its structure can be shunk automatically when moving to pit, can automatically reset equally when leaving, structural stability is improved greatly, and device is protected service life.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing 1; the utility model provides a kind of lift car and to stretch foot protecting plate device; mainly comprise car 8; car 8 lower beam frame front end is provided with protection sole 1 and the fixing support rack 2 of foldable telescopic; that can vertically slide in fixing support rack 2 is provided with removable positioning groove 3; some slidably movable axis bearings 4 are installed in removable positioning groove 3; wherein; each movable axis bearing 4 all level connection joint has removable bracing frame 5, and protection sole 1 is connected in series from top to bottom successively with removable bracing frame 5.
In preferred embodiment of the present utility model; movable connecting panel 6 is provided with above each movable axis bearing 4 corresponding in removable positioning groove 3; and each removable bracing frame 5 front end upper and lower sides is provided with living hinge 7; wherein; be positioned at movable connecting panel 6 to be topmost connected with the upside living hinge 7 of protection sole 1 and the removable bracing frame 5 in below thereof respectively by cable, adjacent removable bracing frame 5 is connected by the two inner side living hinge 7 and movable connecting panel 6.
When ascending for elevator, above-mentioned removable positioning groove 3, arrange movable axis bearing 4 in the inner and removable bracing frame 5 all because gravity naturally droops, device is in extended configuration; When elevator comes downwards to bottom, removable positioning groove 3 contacts pit and up relative to car 8, living hinge 7 starts hinge and movable connecting panel 6 starts to shrink subsequently, and simultaneously movable axis bearing 4 rises mobile relative to car 8, and this timer is in contraction state.Namely foot protecting plate device of the present utility model being under pressure/gravity time automatically retractable.
In addition, be provided with protective case 9 bottom car 8, removable positioning groove 3 cover can be put when device is in contraction state and form protective action in the inner by it.
Visible, this device is reaching elevator safety requirement of shelter---and prevent passenger while car 8 ground is higher than danger of falling from the gap between car 8 and landing sill during stop ground, its structure can be shunk automatically when moving to pit, can automatically reset equally when leaving, structural stability is improved greatly, and device is protected service life.
Finally it should be noted that; the above is preferred embodiment of the present utility model; the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
