Abstract
The utility model discloses an upward-jump safety protection device of a stair of an escalator. The upward-jump safety protection device of the stair of the escalator comprises a contact support, a contact switch, a support, a fixing block, a spring, a bolt, an emergency guide rail and a stair hook, wherein the bolt is installed on the emergency guide rail, the bolt is sleeved with the spring in an embedded mode, the stair hook is installed below the emergency guide rail, the contact support and the emergency guide rail are connected through the support, the emergency guide rail is fixed to the support in a welding mode, the emergency guide rail is fixed through the fixing block, and the contact switch is arranged on the contact support. The upward-jump safety protection device of the stair of the escalator is safe, reliable, simple in structure and small in fitting limit, the space is saved, machining and manufacturing are convenient, the cost is low, and popularization is facilitated.
Description
Technical field
The utility model relates to a kind of escalator safety guard, particularly a kind of step-tripping safety protection device for escalators.
Background technology
At present, general escalator step is all to realize upper jumping safety guard-safeguard by mechanical actions such as urgent pressure rails.Its shortcoming is the safety guard-safeguard that mechanical device can not be realized electric aspect.Once mechanical device lost efficacy, the phenomenon of jumping on step still exists, and causes staircase failure operation, and passenger is damaged.
Utility model content
For problems of the prior art; the purpose of this utility model is do not changing under the prerequisite of original physical construction; provide a kind of by electric switch, make on step to jump after, control whole ladder out of service, to protect a kind of step-tripping safety protection device for escalators of passenger safety.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of step-tripping safety protection device for escalators, comprise contact holder, contact switch, support, fixed block, spring, bolt, urgent guide rail and step hook, on described urgent guide rail, bolt is installed, on described bolt, be nested with spring, described urgent guide rail below is provided with step hook, between described contact holder and urgent guide rail, by support, be connected, described urgent guide rail and support welding are fixed, described urgent guide rail is fixed by fixed block, described contact holder is provided with contact switch.
Adopt after technique scheme, the utlity model has following beneficial effect: the utility model is safe and reliable, simple in structure, fitting limit is little, saves space, and processing and fabricating is convenient, and cost is low, is beneficial to popularization.
Accompanying drawing explanation
Fig. 1 is a kind of step-tripping safety protection device for escalators structural representation of the utility model.
Fig. 2 is a kind of step-tripping safety protection device for escalators normal operating condition of the utility model schematic diagram.
In figure: 1, urgent guide rail; 2, contact holder; 3, contact switch; 4, support; 5, fixed block; 6, spring; 7, bolt; 8, step hook.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further explained.
As shown in Figure 1, a kind of step-tripping safety protection device for escalators, comprise contact holder 2, contact switch 3, support 4, fixed block 5, spring 6, bolt 7, urgent guide rail 1 and step hook 8, on described urgent guide rail 1, bolt 7 is installed, on described bolt 7, be nested with spring 6, described urgent guide rail 1 below is provided with step hook 8, between described contact holder 2 and urgent guide rail 1, by support 4, be connected, described urgent guide rail 1 is welded and fixed with support 4, described urgent guide rail 1 is fixing by fixed block 5, described contact holder 2 is provided with contact switch 3.
As shown in Figure 2, a kind of step-tripping safety protection device for escalators of the utility model is in normal operating condition, and now contact is in normally open.When the upper phenomenon of jumping appears in step, step hook 8 upward movements, thus drive the synchronous upwards pressuring spring 6 of urgent guide rail 1.Meanwhile, be welded on support 4 upward movements on urgent guide rail 1, now the dogleg section of support 4 lower ends is got to the electric shock switch 3 of often opening, make the switch motion of getting an electric shock, thereby the triggering by switch is sent signal to control system, and control system recognizes fault, thereby send, stop terraced instruction.
When safety guard recovers, need after hand reset, whole ladder could continue operation.Avoid automatic reset switch improper because resetting, and caused step again to go up the situation can't detect while jumping.So the utility model is safe and reliable.
