Abstract
The utility model provides an eccentric bushing which can move a base board so that the gauge can be conveniently and rapidly regulated. The eccentric bushing aims to solve the problem that a gauge block is replaced troublesomely when the gauge is regulated. According to the technical scheme, the eccentric bushing for a railway track comprises a round sleeve body and an inner hole, the hole center of the inner hole and the hole center of the outer circle of the sleeve body are deviated, one end of the sleeve body is provided with a ring of boss along the periphery surface of the outer circle of the sleeve body, and the edge of the boss is provided with at least two symmetrical square grooves. By the adoption of the eccentric bushing, the eccentric bushing is embedded into a bolt hole of the base board, the gauge can be regulated by rotating forward and inverted angles, the trouble that the gauge block is replaced repeatedly is avoided, and work efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of railroad track parts, especially a kind of for adjusting the parts of gauge.
Background technology
The railroad track of China is all, by bolt, backing plate is fixed on to a certain position of switch tie at present, and backing plate can not move, and track switch gauge adjustment can only complete by packing the track gauge block of different model into.Use track gauge block to adjust gauge, need when mounted first the track gauge block of regulation use to be beaten into and is arranged on backing plate, then measure gauge, if gauge does not also meet and it will be pounded out, again track gauge block up to specification is beaten into and is fixed on backing plate, and track switch track gauge block type kind is very many, must causes like this railway personnel maintenance loaded down with trivial details, and have a strong impact on operating efficiency.
Utility model content
The purpose of this utility model is loaded down with trivial details in order to overcome the replacing of track gauge block when adjusting gauge, and a kind of eccentric bushing that can make backing plate move is provided, thereby reach, adjusts quickly and easily gauge.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of railroad track eccentric bushing, comprise circular body and endoporus, the cylindrical center of described endoporus Kong center and described body deviates, there is a circle boss one end of described body along body outer circumference surface, and described protruding edge of table has at least two symmetrical square notches.
In one embodiment, the external diameter of described body is 49 ± 0.2mm, and the aperture of described endoporus is 31 ± 0.5mm, and the eccentric throw at the cylindrical center of described endoporus Kong center and described body is 3mm.
In one embodiment, the material of described body is glass fiber reinforced polyamide 66.
Adopt eccentric bushing provided by the utility model, be embedded in the bolt hole of backing plate, by rotating along contrary angle, just can realize the adjustment to gauge, avoided repeatedly changing the loaded down with trivial details of track gauge block, improved widely operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is along the sectional view of AB line in Fig. 1.
The specific embodiment
As shown in Figure 1, 2, railroad track is rounded with the body 1 of eccentric bushing, employing glass fiber reinforced polyamide 66 is made, the external diameter of body 1 is 49 mm, in the centre of body 1, have an eccentric circular hole 2, aperture is 31mm, and the eccentric throw at the cylindrical center of described circular hole 2 Kong centers and described body 1 is 3mm, there is a circle boss 3 one end of described body 1 along body 1 outer circumference surface, and the edge of described boss 3 has at least two symmetrical square notches 4.
During use, eccentric bushing is inlayed to the turnout sleeper bolt hole to backing plate, then with bolt, the endoporus through eccentric bushing is installed to backing plate on switch tie, when needs are adjusted gauge, with spanner, the notch 4 on eccentric bushing is carried out along reverse rotation and just can gauge be adjusted.
Claims (3)
