Abstract
The invention relates to an improved structure of a scraper conveyor, in particular to a wear-resistant scraper conveyor chain structure, which comprises a scraper chain link I (1), a scraper chain link II (2) and a pin shaft (3), wherein the scraper chain link I (1) and the scraper chain link II (2) are rotationally matched through the pin shaft (3), and the wear-resistant scraper conveyor chain structure is characterized in that: a locking step (11) is arranged on the side wall of the scraper chain link I (1), a locking notch (31) is arranged at one end of the pin shaft (3), and the locking notch (31) is meshed with the locking step (11); when the chain links of the scraper are forged, a locking step is reserved in the die, a locking notch matched with the locking step is reserved in the pin shaft, the pin shaft does not randomly rotate along with the chain after being mutually occluded, the synchronous abrasion of the contact surface of the whole chain is ensured, the fluctuating load is decomposed, and the service life of the whole chain is almost the same; simultaneously for the convenience of change, with round pin axle and scraper blade chain link design for detachable connections to guarantee can quick replacement, need not pull down whole chain and maintain.
Description
Technical Field
The invention relates to structural improvement of a scraper conveyor, in particular to a wear-resistant scraper conveyor chain structure.
Background
The abrasion of chains and pin shafts in the dust removal and ash conveying scraper conveying equipment is difficult and difficult faults of a using unit, the whole equipment can be paralyzed and even serious equipment safety accidents can be caused as long as a certain chain or pin shaft of the whole equipment is broken, the service life can be only prolonged relatively through a material or heat treatment process, but the problem that when the pin shaft runs along with the scraper chain synchronously, the pin shaft rotates randomly due to factors such as assembly clearance, load fluctuation caused by fluctuation of feeding quantity, friction force and the like is solved, the chain of a certain section with slightly larger clearance is abraded more and more severely, the chain is broken from the point, the abrasion of the rest chains is very small, and the whole chain can be scrapped due to extrusion after the chain breakage.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the existing defects and provides a wear-resistant scraper conveyor chain structure.
In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a stand wear and tear scraper conveyor chain structure, includes scraper blade chain link one, scraper blade chain link two and round pin axle, scraper blade chain link one and scraper blade chain link two are through round pin axle normal running fit, be equipped with the locking step on the lateral wall of scraper blade chain link one, one of round pin axle is served and is equipped with the fore shaft, fore shaft and locking step interlock.
Preferably, the pin shaft is detachably connected with the first scraper chain link and the second scraper chain link.
Preferably, the detachable connection means that a pin hole is formed in the other end of the pin shaft, and the detachable connection further comprises a bolt, and the bolt is detachably connected with the pin hole.
Preferably, the detachable connection means that the bolt is screwed with the pin hole.
Preferably, the locking step is semicircular.
Preferably, the locking step and the first scraper chain link are of an integrally formed structure.
The wear-resistant scraper conveyor chain structure has the following advantages: when the chain links of the scraper are forged, a locking step is reserved in the die, a locking notch matched with the locking step is reserved in the pin shaft, the pin shaft does not randomly rotate along with the chain after being mutually occluded, the synchronous abrasion of the contact surface of the whole chain is ensured, the fluctuating load is decomposed, and the service life of the whole chain is almost the same; simultaneously for the convenience of change, with round pin axle and scraper blade chain link design for detachable connections to guarantee can quick replacement, need not pull down whole chain and maintain.
Drawings
FIG. 1 is a first schematic structural view of a wear-resistant scraper conveyor chain structure of the present invention;
FIG. 2 is a second schematic structural view of the wear-resistant scraper conveyor chain structure of the present invention;
fig. 3 is a schematic cross-sectional view of the wear-resistant scraper conveyor chain structure of the present invention.
Description of the drawings: 1. a first scraper chain link; 11. a locking step; 2. a second scraper chain link; 3. a pin shaft; 31. locking the opening; 32. a pin hole; 33. and (4) a bolt.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
As shown in fig. 1 to 3, the wear-resistant scraper conveyor chain structure comprises a scraper chain link 1, a scraper chain link 2 and a pin shaft 3, wherein the scraper chain link 1 and the scraper chain link 2 are rotationally matched through the pin shaft 3, a locking step 11 is arranged on a side wall of the scraper chain link 1, a locking notch 31 is arranged at one end of the pin shaft 3, and the locking notch 31 is engaged with the locking step 11; the pin shaft 3 is detachably connected with the first scraper chain link 1 and the second scraper chain link; the detachable connection specifically means that a pin hole 32 is formed in the other end of the pin shaft 3, and the detachable connection further comprises a bolt 33, and the bolt 33 is detachably connected with the pin hole 32; the detachable connection means that the bolt 33 is in threaded connection with the pin hole 32; the locking step 11 is semicircular; the locking step 11 and the scraper chain link I1 are of an integrated structure.
When concrete implementation, after round pin axle 3 inserts scraper blade chain link 1 and scraper blade chain link two 2, scraper blade chain link 1 and scraper blade chain link two 2 can carry out normal running fit through round pin axle 3 on the one hand, interlock through locking step 11 on the scraper blade chain link 1 and the fore shaft 31 on the round pin axle 3 simultaneously, thereby can restrict round pin axle 3 and can not appear the pivoted condition, change the convenience for the dismantlement of better assurance round pin axle simultaneously, still be equipped with pinhole 32 on round pin axle 3, directly pass through detachable connections between bolt 33 and the pinhole 32, thereby realize pulling out the back from pinhole 32 when bolt 33, round pin axle 3 can be fast from scraper blade chain link 1 and the change of taking off of scraper blade chain link two 2.
The above embodiments are preferred embodiments of the present invention, and those skilled in the art can make variations and modifications to the above embodiments, therefore, the present invention is not limited to the above embodiments, and any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
