Abstract
The invention discloses a protective structure for a comb plate. The protective structure comprises a comb supporting plate component supporting the comb plate. The comb supporting plate component is fixedly connected with a connecting plate. A long threaded rod is fixed to the end of the connecting plate through a bolt. A locknut is arranged in the middle of the long threaded rod. A limiting switch assembly is fixedly connected with the tail portion of the long threaded rod and comprises a wave-shaped corrugated plate and a limit switch. The limit switch is fixed to the position over the corrugated plate. The corrugated plate is in contact with the limit switch. In this way, the passengers can be prevented from being nipped by the comb plate, the lift taking risk caused by overturning of a middle plate of a front edge plate can also be lowered, and therefore the lift taking safety of the passengers is protected. Besides, the overall protective structure is simple, convenient to adjust, manufacture and install and practical.
Description
technical field:
The present invention relates to the fishback operator guards on a kind of staircase.
background technology:
Stair comb plate is positioned at step or the pedal gangway of operation, for convenience of the upper and lower transition of passenger, the parts be meshed with step or pedal, fishback while be supported on front edge board, another side is as the stationary plane of comb, it can make of aluminium alloy extrusions, also comparatively thick carbon steel plate can be used to make, and staircase is in normal operation, on the one hand clip to fishback fishback can be caused to damage when foreign matter squeezes, thus cause the personal safety of passenger to be on the hazard, owing to usually overlapping in the middle part of fishback parts and front edge board on the other hand, sometimes because External Force Acting makes lap-joint stagger, owing to not easily discovering, so the risk of plate upset in existing.
summary of the invention:
The technical problem to be solved in the present invention is to provide one and passenger can either be avoided to suffer fishback to squeeze folder, can reduce again because plate upset causes the risk of boarding danger in front edge board, improve the fishback operator guards of the safety of passenger's boarding.
For solving the problem, the present invention is achieved by the following technical solutions:
A kind of fishback operator guards, comprise fishback passive comb stay bearing plate parts, described comb stay bearing plate parts are fixedly connected with a plate, described connecting panel end bolt is fixed with a long bolt, a black nut is provided with in the middle part of described long bolt, limit switch assembly is fixedly connected with at described long bolt afterbody, described limit switch assembly comprises corrugated plating and the limit switch of a undaform, described limit switch is fixed on directly over corrugated plating, described corrugated plating contacts with limit switch and can realize the switch motion of limit switch in movable process.
As preferably, the long bolt section between described black nut and connecting panel is provided with captive nut, between described captive nut and black nut, is provided with one can play resilient mounting spring to black nut.
As preferably, described corrugated plating profile is L-type, and its undulatory side plate and long bolt be arranged in parallel, and its vertical plate and described long bolt end bolt are connected and fixed.
Compared with prior art; usefulness of the present invention is: this fishback operator guards is made up of two groups of limit switch assemblies; be arranged on the bracing frame of comb stay bearing plate; by the way moving of wave-shape board; impel switch motion; thus; passenger can either be avoided to suffer fishback to squeeze folder; can reduce again because in front edge board, plate upset causes the risk of boarding danger, and then ensure passenger's boarding safety, and integral structure is simple; easy to adjust; fabrication and installation are convenient and practical, have higher economic benefit, are applicable to applying.
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;
In figure: 1, comb stay bearing plate parts 2, connecting panel 3, long bolt 4, black nut 5, corrugated plating 6, limit switch 7, captive nut 8, spring
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of fishback operator guards of the present invention, as shown in Figure 1, comprise fishback passive comb stay bearing plate parts 1, described comb stay bearing plate parts 1 are fixedly connected with a plate 2, described connecting panel 2 end bolt is fixed with a long bolt 3, a black nut 4 is provided with in the middle part of described long bolt 3, limit switch assembly is fixedly connected with at described long bolt 3 afterbody, described limit switch assembly comprises corrugated plating 5 and the limit switch 6 of a undaform, described limit switch 6 is fixed on directly over corrugated plating 5, described corrugated plating 5 contacts with limit switch 6 and can realize the switch motion of limit switch 6 in movable process, limit switch 6 action can better be triggered for making corrugated plating 5, long bolt between described black nut 4 and connecting panel 23 sections is provided with captive nut 7, one can play resilient mounting spring 8 to black nut 4 is provided with between described captive nut 7 and black nut 4, thus, when Compress Spring 8, corrugated plating 5 is subjected to displacement, impel limit switch 6 action, when fishback parts are subject to external force forward, stagger with the Zhong Ban lap-joint of front edge board, also limit switch 6 action can be made, and then make staircase out of service, ensure the safety of staircase, in addition, conveniently corrugated plating 5 installation and be improve further the sensitivity that it triggers limit switch 6, described corrugated plating 5 profile is L-type, its undulatory side plate and long bolt be arranged in parallel, its vertical plate and described long bolt 3 end bolt are connected and fixed, thus in specific implementation process, owing to increasing limit switch 6 in fishback parts, by double nuts machinery anti-loose structure, long bolt 3 can be made firmly to locate, during Compress Spring 8, corrugated plating 5 is subjected to displacement, limit switch 6 is impelled to work, and fishback parts by external force forward time, stagger with Zhong Ban lap-joint, also limit switch 6 action can be made, thus, extrude backward due to foreign matter when fishback parts or be subjected to displacement forward due to external force, ladder can be stopped in time by limit switch, ensure passenger safety.
Above-mentioned fishback operator guards is made up of two groups of limit switch assemblies; be arranged on the bracing frame of comb stay bearing plate, by the way moving of wave-shape board, impel switch motion; thus; passenger can either be avoided to suffer fishback to squeeze folder, can reduce again because plate in front edge board overturn the risk of the boarding danger caused, and then guarantee passenger boarding safety; and integral structure is simple; easy to adjust, fabrication and installation are convenient and practical, have higher economic benefit.
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.
