Abstract
The utility model discloses an escalator chain-broken protection device, and relates to the technical field of escalators. The escalator chain-broken protection device comprises a limiting switch. A beating stick is placed at one end of the limiting switch and is placed on a sleeve in a reeling mode through bolts. The escalator chain-broken protection device is characterized in that flat plates perpendicular to the length direction of the beating stick are placed on one side of the limiting switch, wherein the side of the limiting switch is far away from the beating stick. By means of the escalator chain-broken protection device, the purposes that the escalator chain-broken protection device is simple in structure and high in stability and the security coefficient after an escalator is broken is increased are achieved.
Description
Technical field
The utility model relates to the technical field of escalator.
Background technology
Present escalator is mainly to complete driving by the chain of driving wheel, makes the footway panel move, when accident; rod is got in the chain chain rupture, plays rod and rotates the triggering limit switch around sleeve; force the footway panel out of service, protection passenger's safety.But present sleeve area of contact is less, causes sensitivity not high, and required time out of service is longer.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, and stability is high, has increased the escalator chain breakage protection device of the safety factor after the staircase chain rupture.
A kind of escalator chain breakage protection device comprises limit switch, and rod is played in an end setting of limit switch, beat rod by bolt around the home on sleeve, it is characterized in that above-mentioned beat rod away from a side of limit switch arrange the flat board vertical with beating excellent length direction.
The utility model adopts technique scheme, compared with prior art has following advantage: after the chain rupture of host driven chain, chain can land and get to rod, plays rod and rotates around sleeve, triggers limit switch, and the additional brake forced brake shuts down staircase.Increase flat board on rod newly beating, increased the area of contact of playing rod, made and play rod and can better contact with chain, thereby increased the safety factor after the staircase chain rupture.Simple in structure, stability is high.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated:
As shown in Figure 1; a kind of escalator chain breakage protection device comprises limit switch 1, and rod 2 is played in an end setting of limit switch 1; beat rod 2 by bolt around the home on sleeve 3, above-mentioned beat rod 2 away from a side of limit switch 1 arrange the flat board 4 vertical with beating excellent 2 length directions.
After the chain rupture of host driven chain, chain can land and get to rod, plays rod 2 and rotates around sleeve 3, triggers limit switch 1, and the additional brake forced brake shuts down staircase.Increased newly on 2 dull and stereotypedly 4 playing rod, increased the area of contact of playing rod 2, made and play rod 2 and can better contact with chain, thereby increased the safety factor after the staircase chain rupture.
