Description
Technical field
The invention belongs to escalator field more particularly to a kind of no step axle escalators.
Background technology
In the prior art, escalator step operation logic is that drive sprocket drives two steps in the right and left arrangement
Chain moves in closed loop track, wherein manned step is mounted in step chains, and is driven by step chain.Step chains master at present
It is that a step axle is equipped among the chain of both sides to want structure（As shown in Figure 1）, which is directly linked to be the right and left chain
Whole, step axle 99 is equipped with plastic sleeve 97 and clamp 98, and step is directly installed on the axle sleeve of step axle, and step
It can horizontally slip on step axle, front and back step is aligned in step, determine without locking clamp after side set.Existing band step axle knot
Structure principle is simple, but still has the following disadvantages：（1）, it is higher to installing the skill requirement of step personnel, exist and wind out of control be installed
Danger, and repeat adjustment step alignment and need a large amount of time and efforts；（2）, clamp radially folder step axle locking mode still have
The risk of axial movement；（3）, due to there is step axle in step axle construction to share part passenger's load, most of manufactures
Step is made opposite lightweight by commercial city, and relatively thin wall thickness and reinforcing rib propose higher want to Casting Equipment and technique
It asks, defect rate rises therewith, increases security risk；（4）, the step chain with step axle account for larger volume, transport and storage
The cost is relatively high；（5）, each more than ten centimeters one grade of step axle, narrow space so that maintenance is inconvenient, and is tieed up on step axle
There is security risk when protecting operation, has and step on the empty risk fallen.
Invention content
In order to solve the above technical problem, the present invention provides a kind of no step axle escalators, by cancelling step chains
On step axle, step is directly installed in step chains, stable structure, small, install convenient, be easy to transport storage,
Maintenance facilitates.
For this purpose, the present invention uses following technical scheme：A kind of no step axle escalator, including driving unit and step list
Member is driven by driving unit and step unit is driven to be moved, it is characterised in that：If the step unit include step chains and
Dry step, is arranged long pin shaft in the step chains, the long pin shaft include before, during and after three sections, the leading portion of wherein long pin shaft passes through
Bearing is socketed an idler wheel, and an axle sleeve is socketed on the long pin shaft posterior segment, and segment trailer is equipped with a baffle ring after the long pin shaft, described
A baffle ring for being limited to axle sleeve is equipped between baffle ring and axle sleeve, axle sleeve rear end extension is equipped with limited step, axis
It covers front end and is equipped with flank, cover connected nut, washer and snap-gauge on the flank successively, the step is equipped with claw, described
Claw is mounted on axle sleeve, and the snap-gauge blocks step claw, passes through the washer and nut check snap-gauge.
Further, the snap-gauge be equipped with long lumbar hole, the axle sleeve be equipped with non-threaded face, the two of the non-threaded face
Side is equipped with symmetrical plane, and when snap-gauge pierces into axle sleeve, the symmetrical plane of the long lumbar hole and axle sleeve cooperates, and limits the card
Plate rotates on the axle sleeve；The snap-gauge is equipped with boss, and an inclined-plane, the boss of the snap-gauge are equipped on the claw of step
The claw of clamping step.

Both ends.
Further, the limited step of axle sleeve rear end extension is equipped with card slot, and a dustproof cover is fastened by card slot.
The advantages of this programme, is：It is changed to setting long pin shaft in former step shaft position, long pin shaft is equipped with axle sleeve, and in institute
Shaft end setting baffle ring of having strong market potential is stated, the baffle ring can be directly mounted at by retainer ring spacing axle sleeve, step claw on the axle sleeve
Afterwards, step claw is blocked by above-mentioned snap-gauge, then by above-mentioned washer, nut check snap-gauge, to realize step chains and step
Mounting means.
In order to ensure tightness, two symmetrical planes are arranged in the non-threaded place of the axle sleeve, while the inner ring of the snap-gauge is set
Long lumbar hole is set, when the snap-gauge pierces into axle sleeve, the symmetrical plane of the long lumbar hole and axle sleeve has played the mutual limitation snap-gauge
It is rotated on the axle sleeve；Boss is set on the snap-gauge, an inclined-plane, the boss card of the snap-gauge are set on step claw
Tight step claw, makes step that can not rotate, to ensure that the ability of fastening step.
For proof strength, the intensity for increasing step is needed, so that step is itself served as the effect of a part of step axle, by two
Side step chains are linked to be entirety.
In order to ensure that better anti-loosing effect, the washer enhance anti-loosing effect, the spiral shell of the axle sleeve using wave washer
Line and the nut use fine thread structure, not only increase the locking screw number of turns, and also assure the precision of locking screw, with
Convenient for enhancing anti-loosing effect.
In order to reduce abrasion, anti-attrition set is arranged in the both ends between the long pin shaft and the axle sleeve, and the anti-attrition set makes
With exempting from lubriation material.
In order to improve structural life-time, the limited step of axle sleeve rear end extension is equipped with card slot, and one is fastened by card slot
Dustproof cover avoids impurity and rain erosion.
The present invention has the advantages that compared with prior art：After described device,（1）, pass through finishing
Parts ensure the installation accuracy of step, reduce risk caused by due to installation personnel is lacked experience the reason of, improve
Installation effectiveness.（2）, clamp step axle compared to existing clamp and lock cascading fashion, step is compressed simultaneously by axially mounted snap-gauge
More direct by the way of nut check snap-gauge, eliminating step has the risk of axial displacement.（3）, enhanced step gathers around
There are relatively sturdy wall thickness and reinforcing rib, alleviate to Casting Equipment and technique rigors, improve yield rate, reduces safety
Risk.（4）, eliminate step axle, stacked system transport and storage may be used in step chains, reduces manufacturing cost, improves
Utilization of area rate.（5）, eliminate step axle, in installation and during maintenance, have great space that can make for operating personnel
With without the operation on step axle, improving maintenance efficiency and safety.
