Abstract
The utility model is related to a kind of escalator reduction gearbox output shaft end cap anti-drop devices, including output shaft and end cap, what is connect with the end cap on the output shaft is provided with one and runs through output shaft radial slot on one side, and what is be connected to the output shaft on the end cap is provided with a muscle on one side；The location of the location of described muscle and described slot correspond；The muscle is stuck in the connection that output shaft and end cap are realized in the slot.The utility model can effectively prevent reduction gearbox output shaft end cap to fall off.
Description
Technical field
The utility model is related to escalator security technology areas, more particularly to a kind of escalator reduction gearbox output shaft
End cap anti-drop device.
Background technology
Escalator has become the important component of citizen's masses' go off daily, and safety has been that city operations are safe not
The ring that can or lack.While offering convenience, the accident of generation is also continuously increased escalator.The function of escalator and spy
Point determines that its majority is installed in the place that the flows of the people such as market, supermarket, subway station are extremely concentrated, once accident occurs then matchmaker
Body exposure rate is high, and social influence is serious.Although escalator accident death rate is low compared with elevator, thus to the injury of the wounded's generation
And social influence is very serious.
In escalator accident, lead that accident is more with rollback, rollback accident then mainly by the fracture of main drive chain, fall off and draw
It rises.And falling off for main drive chain is related with falling off for reduction gearbox output shaft end cap, therefore, there is an urgent need for one kind capable of preventing escalator
The device of reduction gearbox output shaft end cap anticreep.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of escalator reduction gearbox output shaft end cap anticreep dresses
It sets, reduction gearbox output shaft end cap can be effectively prevent to fall off.
Technical solution adopted by the utility model to solve its technical problems is：A kind of escalator reduction box output is provided
Hubcap anti-drop device, including output shaft and end cap, what is connect with the end cap on the output shaft is provided with one and passes through on one side
Output shaft radial slot is worn, what is be connected to the output shaft on the end cap is provided with a muscle on one side；Position residing for the muscle
It sets and is corresponded with the location of the slot；The muscle is stuck in the connection that output shaft and end cap are realized in the slot.
The periphery of the output shaft is uniformly arranged there are four key.
The width of the slot is 6mm, depth 10mm.
The width of the muscle is 5mm, length 50mm, thickness 9mm.
Advantageous effect
Due to the adoption of the above technical solution, the utility model compared with prior art, has the following advantages that and accumulates
Pole effect：The utility model prevents reduction gearbox output shaft the increase card slot on output shaft and on end cap by way of increase muscle
In rotary course, due to vibration cause, cause end cap fixing bolt to loosen, key is caused to be deviate from, causes minor sprocket to be detached from and slow down
Case output shaft eventually leads to main drive chain and falls off, and causes escalator rollback accident.
Description of the drawings
Fig. 1 is the structural schematic diagram of output shaft in the utility model；
Fig. 2 is the structural schematic diagram of end cap in the utility model；
Fig. 3 is the side view of Fig. 2.
Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiment of the utility model is related to a kind of escalator reduction gearbox output shaft end cap anti-drop device, such as Fig. 1, figure
Shown in 2 and Fig. 3, including output shaft 1 and end cap 2, what is connect with the end cap 2 on the output shaft 1 is provided with one and passes through on one side
Output shaft radial slot 11 is worn, what is connect with the output shaft 1 on the end cap 2 is provided with a muscle 21 on one side；The muscle 21
Location is corresponded with 11 location of the slot；The muscle 21, which is stuck in the slot 11, realizes output shaft 1 and end
The connection of lid 2.The periphery of the output shaft 1 is uniformly arranged there are four key 12.
In present embodiment, the width of the slot 11 is 6mm, depth 10mm.The width of the muscle 21 is 5mm, length
For 50mm, thickness 9mm.In use, only needing that after muscle 21 is caught in the slot 11 completion can be connected, more for connection
To be secured, output shaft 1 and end cap 2 can be connected by fixing bolt.
It is not difficult to find that the utility model prevents from subtracting the increase card slot on output shaft and on end cap by way of increase muscle
Fast case output shaft, due to vibration cause, causes end cap fixing bolt to loosen, key is caused to be deviate from, cause chainlet in rotary course
Wheel is detached from reduction gearbox output shaft, eventually leads to main drive chain and falls off, and causes escalator rollback accident.
