Abstract
The utility model relates to a track segmented connecting pin shaft used for a track crane, which belongs to the mechanical machining field. The connecting pin shaft changes the one-segment connecting pin shaft into segmented connecting pin shafts; track links are connected into a whole through a left track pin shaft and a right track pin shaft. The structure reduces the manufacturing precision of the track pin shaft and reduces the distortion force on the pin shaft generated by the deformation of the track and can effectively improve the service life of the pin shaft, reduce the labor intensity of workers while reducing the production cost.
Description
Technical field
The utility model relates to a kind of crawler belt sectional type that is used for crawler crane and connects bearing pin, belongs to the construction machinery and equipment manufacture field.
Background technology
At present, process at construction machinery industry, the crawler crane of making, caterpillar machineries such as crawler type roller, connection between caterpillar block mostly is to adopt bearing pin to connect, the structure of existing crawler belt bearing pin is whole one-part form bearing pin, the requirement on machining accuracy height, especially in crawler belt work engineering, the front and back caterpillar block that links to each other by the crawler belt bearing pin can produce bigger distortion power respectively on the crawler belt bearing pin, make crawler belt bearing pin torsional deflection even fracture easily, need often to change, give workman's operation, maintenance brings inconvenience, has also strengthened productive costs simultaneously, does not have good terms of settlement so far.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, accuracy of manufacture is low relatively slightly, utilize left and right two sections crawler belt bearing pins that caterpillar block is connected, can make bearing pin under abominable road conditions, reduce the damage that causes because of the crawler belt distortion, to overcome the deficiencies in the prior art part.
The purpose of this utility model realizes with following technical scheme: a kind of crawler belt sectional type connects bearing pin, comprise upper track plate, lower track plate, fastener and device the bearing pin that is connected in upper track plate, lower track plate centre, it is characterized in that: connect bearing pin and be made up of left bearing pin and two sections institutes of right bearing pin, left bearing pin and right bearing pin adopt and flexibly connect is an integral body.
The utility model has the advantages that: this structure has reduced the accuracy of manufacture of crawler belt bearing pin, and the distortion power that has reduced the crawler belt distortion and bearing pin is produced in the service life that can effectively improve bearing pin, has also alleviated working strength of workers when reducing production costs.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the utility model structural representation:
Among the figure: 1, upper track plate, 2, lower track plate, 3, fastener, 4, connect bearing pin, 4-1, left bearing pin, 4-2, right bearing pin.
The specific embodiment
As shown in the figure: a kind of crawler belt sectional type connects bearing pin, comprise that upper track plate 1, lower track plate 2, fastener 3 and device are connected bearing pin 4 in the middle of upper track plate 1, lower track plate 2, it is characterized in that: connect bearing pin 4 and be made up of left bearing pin 4-1 and two sections institutes of right bearing pin 4-2, left bearing pin and right bearing pin adopt and flexibly connect is an integral body.
