Abstract
The utility model relates to a stair coupling structure. The technical problem to be solved is to cause a main shaft easily to disengage from the stair coupling structure of chains, so as to cause the stairs to disengage from the main shaft easily. The utility model comprises stairs. The utility model is characterized in that both sides below the stairs are respectively provided with a short main shaft, the outer end of which is connected with the chains. The utility model is used in an escalator or a moving sidewalk.
Description
[technical field]
The utility model relates to a kind of step draw bail that is used for escalator or moving sidewalk.
[background technology]
The existing step draw bail that is used in escalator or moving sidewalk, as Fig. 1, shown in 2, comprise a plurality of steps 1 ', main shaft 2 ' and chain 3 ', main shaft 2 ' connects by chain hinge pin 4 ' and jump ring 5 ' with chain 3 ', step 1 ' connects by step axle sleeve 6 ' and location retainer 7 ' with main shaft 2 ', escalator or moving sidewalk are when Installation and Debugging or maintenance, because main shaft is a major axis, its two ends are connected with chain, and main shaft can not break away from chain, thereby make the disengaging complicated operation of main shaft and step, time-consuming, cause the operational space little, maintenance time is long, inefficiency brings tong also can for debugging and maintenance, safety hazard such as pinch.
[utility model content]
The technical assignment of technical problem to be solved in the utility model and proposition is the defective that overcomes above-mentioned prior art, and a kind of step draw bail that makes main shaft be easy to break away from chain is provided, and makes step can easily break away from main shaft.
The technical scheme that the utility model adopted is such: novel step draw bail, comprise step, and it is characterized in that the both sides of step below respectively are provided with a short main shaft, the outer end of this short main shaft connects chain.The utility model connects with chain by short main shaft, and the short main shaft of both sides is separate, very convenient disengaging operation of lacking main shaft and chain, thus make step can easily break away from short main shaft, convenient for maintaining has improved work efficiency; After step was broken away from, the space of operation was big, made things convenient for Installation and Debugging and maintenance and made the operator obtain safety control (hand, pin are difficult for being pressed from both sides) preferably.
Described novel step draw bail, the both sides of step below respectively are provided with an axle sleeve, and short main shaft places axle sleeve, and axle sleeve is locked on the short main shaft with a location retainer, the outer terminal inner lining one and the affixed bearing pin of chain of short main shaft, short main shaft is connected with jump ring with bearing pin.
Described novel step draw bail, each is affixed with short main shaft with a bolt in the both sides of step below, outer terminal inner lining one sleeve pipe of short main shaft, this sleeve pipe is built-in with an adapter shaft that is fixed on the chain.
Described novel step draw bail, the inner of short main shaft is provided with the through hole of a convenient maintenance, inserts a lever in through hole, utilizes lever will lack main shaft and chain disengaging then.
The used short main shaft of the utility model is easy to break away from chain, thereby makes step can easily break away from short main shaft, makes things convenient for Installation and Debugging and maintenance, has improved work efficiency; After step was broken away from, the space of operation was big, made the operator obtain safety control preferably.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
