Description
Technical field
The utility model belongs to elevator technology field, particularly a kind of escalator Anti-moving step axle sleeve assembly.
Background technology
Escalator combined by the travelling apron of the chain-linked conveyer of a unique construction form and two special structure forms, with circulating motion ladder road, in order to the fixing power driven equipment of the conveying people that tilts up or down between the different floor heights of building.Escalator is made up of the handrail (belt conveyer of distortion) of terraced road (apron conveyor of modification) and both sides.Its major part has step, conduction chain and sprocket wheel, guide track system, main transmission (comprising electrical motor, speed reduction gearing, drg and intermediate transmission link etc.), drive shaft, terraced road tightening device, handrail system, pecten, staircase skeleton and electric system etc.Step moves horizontally at passenger entrance place (facilitating passenger's ascending stair), forms ladder gradually later; Fading away close to exit ladder, step moves horizontally once again.These motions are all walked along different step roller tracks respectively by step main wheel, jockey pulley to realize.Escalator can be widely used in the place that the stream of peoples such as station, harbour, market, airport and subway concentrate.
Escalator is installed on conduction chain by its step axle, and step axle outside need makes step axle and chain shaft carry out the stuck location of axis by axle sleeve and hoop component.In step operational process, be normal-running fit between step axle and axle sleeve, but end float misalignment can not occur.Existing axle sleeve is for being sleeved on outside step axle, clip is then axially positioned on the end of axle sleeve, often need during installation to rely on the experience of workmen axle sleeve and clip accurately could be located, installation is wasted time and energy, and easily there is location inaccuracy, cause the play between axle sleeve and step axle, affect step traveling comfort and safety.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to be easy to location, is easy to install, effectively ensures the escalator Anti-moving step axle sleeve assembly of axle sleeve installation site precision.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of escalator Anti-moving step axle sleeve assembly, it is characterized in that: by axle sleeve, clip and lock bolt are formed, described axle sleeve is by body, radial location platform is formed, radial location platform is shaped with on the top of body, symmetrical two halves ring shaped axial positioning groove is shaped with in one end of body, described clip is two halves formula clip, the bolt-locking platform that two halves formula clip is shaped with by half hoop body and upper end is formed, half hoop body of this two halves formula clip is inlaid in described two halves ring shaped axial positioning groove respectively, the described lock bolt of common installation in the bolt-locking platform of two halves formula clip.
And the bolt-locking platform of described two halves formula clip is positioned at the radial location platform top of axle sleeve body.
And described axle sleeve is plastic axle sleeve.
Advantage of the present utility model and beneficial effect are:
1, this escalator Anti-moving step axle sleeve assembly, by making axial location groove on the body of axle sleeve, adopt semi-circular clip, can directly half hoop body of clip be installed in this axial location groove, directly can by locked clip device by lock bolt, realize the locking to step axle, thus the very easy axial location realizing axle sleeve.
2, this escalator Anti-moving step axle sleeve assembly, for ensureing the structural strength of axle sleeve, its dead axle adopts symmetrical two halves structure to positioning groove, all connecting portion is had in the upper end of the body of axle sleeve and lower end, the bolt-locking platform of two halves formula clip is positioned at the radial location platform top of axle sleeve body, thus can avoid the joint portion of axle sleeve upper end.
3, this escalator Anti-moving step axle sleeve assembly, scientific structure design is reasonable, has and is easy to location, is easy to install, effectively ensures the advantage of axle sleeve installation site precision.

Fig. 2 is the structural representation of clip of the present utility model.
Description of reference numerals:
1-axle sleeve, 2-clip, 3-connecting portion, 4-radial location platform, 5-body, 6-axial location groove, 7-bolt-locking platform, 8-half hoop body.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of escalator Anti-moving step axle sleeve assembly, it is by axle sleeve 1, clip 2 and lock bolt (omission) are formed, described axle sleeve is by body 5, radial location platform 4 is formed, radial location platform is shaped with on the top of body, symmetrical two halves ring shaped axial positioning groove 6 is shaped with in one end of body, described clip is two halves formula clip, the bolt-locking platform 7 that two halves formula clip is shaped with by half hoop body 8 and upper end is formed, half hoop body of this two halves formula clip is inlaid in described two halves ring shaped axial positioning groove respectively, in the bolt-locking platform of two halves formula clip, jointly lock bolt is installed.
The principle of work of this escalator Anti-moving step axle sleeve assembly is:
By making axial location groove on the body of axle sleeve, adopt semi-circular clip, can directly half hoop body of clip is installed in this axial location groove, directly can by locked clip device by lock bolt, realize the locking to step axle, thus the very easy axial location realizing axle sleeve.For ensureing the structural strength of axle sleeve, its dead axle adopts symmetrical two halves structure to positioning groove, all have connecting portion 3 in the upper end of the body of axle sleeve and lower end, the bolt-locking platform of two halves formula clip is positioned at the radial location platform top of axle sleeve body, thus can avoid the joint portion of axle sleeve upper end.
Although disclosed embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that, in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, and therefore scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
