Description
Technical Field
The utility model belongs to the technical field of scraper connecting devices.
Background
The hinge device is a linkage point for coordinating, walking and steering of the front frame and the rear frame of the scraper, wherein the pin shaft sleeve is subjected to the action of left-right rotation and up-down extrusion of the front arm and the rear arm and is a main wearing part of the device; the abrasion of the pin shaft sleeve causes the increase of the gap between the rear arm of the scraper and the pin shaft sleeve, the up-down amplitude of the front and rear frames is increased during walking, and the pin shaft is seriously broken; because the upper pin shaft sleeve and the lower pin shaft sleeve are welded and fixed on the forearm to form a whole, the pin shaft and the pin shaft sleeve are made of special materials, and a great deal of time and expense are required for maintenance and replacement of the pin shaft and the pin shaft sleeve each time.
In recent years, the domestic patent database discloses some similar technical reports of middle hinge structures of the scraper:
[ application number ] ZL2020200313990, [ name ] a scraper middle part hinge structure and scraper, CN211765869U discloses a scraper middle part hinge structure and scraper, includes: the middle hinged short shaft is characterized in that one end of the middle hinged short shaft is a large end, the other end of the middle hinged short shaft is a small end, the large end of the middle hinged short shaft is connected with the positioning steel sleeve through a long bolt, and the small end of the middle hinged short shaft is provided with the locking steel sleeve; the positioning steel sleeve is welded on the middle plate of the rear frame; the joint bearing is arranged in the middle of the middle hinged short shaft, one end of the locking steel sleeve is connected with the middle hinged short shaft through a locking bolt, the other end face of the locking steel sleeve is tightly pressed against the inner ring end face of the joint bearing, and the lower end face of the pressing steel sleeve is tightly pressed against the outer ring end face of the joint bearing. The device still has the problems that the short shaft is easy to wear and is not easy to replace.
Disclosure of Invention
The utility model provides a scraper hinge structure which is reasonable in installation structure, convenient to replace and low in operation and maintenance cost, and solves the technical problems that a pin shaft and a pin shaft sleeve of the conventional hinge structure are not easy to replace, the replacement cost is high and the like.
The utility model provides a scraper hinge structure, which comprises a front arm and a rear arm which are used for connecting a scraper main body, a pin shaft used for connecting the front arm and the rear arm together in a hinge mode, and pin shaft sleeves welded and fixed on two sides of the front arm, wherein a gap is reserved between the pin shaft sleeves and the rear arm on two sides of the front arm, a gasket is arranged in the gap and can rotate relative to the front arm and the rear arm, the outer diameter of the gasket is larger than the outer diameter of the pin shaft sleeve, the inner diameter of the gasket is equal to the inner diameter of the pin shaft sleeve, the pin shaft sequentially penetrates through the rear arm, the gasket, the pin shaft sleeve and the front arm from outside to inside, the gasket is made of 45# steel, and the hardness is smaller than that of the rear arm, the pin shaft sleeve, the front arm and the pin shaft.
According to the utility model, the hinge device pin shaft sleeve part of the scraper is modified, part of the original pin shaft sleeve is cut off between the front arm and the rear arm, the common steel movable gasket which is easy to replace is added, when the gasket is worn to a certain extent, the gasket can be replaced in time to protect the pin shaft and the rest part of the pin shaft sleeve, so that the maintenance cost of the scraper is reduced, the technical effect of the service time of the scraper is increased, the working efficiency of the scraper is improved, the technical problems that the existing hinge structure pin shaft and pin shaft sleeve are difficult to replace, the replacement cost is high and the like are solved, and the scraper has the advantages of reasonable installation structure, convenience in replacement and low operation and maintenance cost.

Fig. 2 is a second structural schematic of the present utility model.
Wherein: 1-pin shaft, 2-pin shaft sleeve, 3-front arm, 4-rear arm and 5-gasket.
Detailed Description
The utility model will be further described with reference to the following specific drawings and examples.
As shown in fig. 1-2, the utility model mainly comprises a front arm 3 and a rear arm 4 which are used for connecting a main body of the forklift, a pin shaft 1 used for hinging the front arm 3 and the rear arm 4 together, and pin shaft sleeves 2 welded and fixed on two sides of the front arm 3, wherein a gap is formed between the pin shaft sleeves 2 on two sides of the front arm 3 and the rear arm 4, a gasket 5 is arranged in the gap, the gasket 5 can rotate relative to the front arm 3 and the rear arm 4, the outer diameter of the gasket 5 is larger than the outer diameter of the pin shaft sleeve 2, the inner diameter of the gasket 5 is equal to the inner diameter of the pin shaft sleeve 2, the pin shaft 1 sequentially passes through the rear arm 4, the gasket 5, the pin shaft sleeve 2 and the front arm 3 from outside to inside, the gasket 5 is made of 45# steel, and the hardness is smaller than that of the rear arm 4, the pin shaft sleeve 2, the front arm 3 and the pin shaft 1.
When the scraper is in operation, the front arm 3 and the rear arm 4 relatively rotate, the gasket 5 is made of 45# steel, the hardness is smaller than that of the rear arm 4, the pin shaft sleeve 2, the front arm 3 and the pin shaft 1, the gasket 5 is worn preferentially, when the gasket 5 is worn to a certain degree, the gasket 5 is replaced timely, so that the hinged pin shaft 1 and the pin shaft sleeve 2 are protected, the loss of the pin shaft 1 and the pin shaft sleeve 2 is reduced, the gap between the scraper rear arm 4 and the pin shaft sleeve 2 caused by wear is prevented from being increased, the upper and lower amplitude of a front frame and a rear frame is increased during walking, and the maintenance cost of the scraper is reduced.
