Abstract
The utility model relates to a heavy load welding chain is established ties by a plurality of chain units and forms, and every chain unit comprises the link joint that bends, round pin axle and sleeve, its characterized in that the chain inboard that bends is equipped with left link joint, intermediate junction board and right link joint, a left side link joint with pass through between the link joint of the right side the intermediate junction board is connected, the intermediate junction board is slantly distributed, left side link joint the intermediate junction board with right side link joint is the integration and distributes, the sleeve cup joints the outside of round pin axle, respectively be equipped with at telescopic both ends left side link joint, respectively be equipped with at the both ends of round pin axle right side link joint. The utility model provides a pair of heavy load welding chain, this chain compact structure, the handling ease, the cooperation is firm just resistance to wears, has improved the chain greatly and has just born the life under the heavy load condition at abominable operational environment.
Description
Technical field
This utility model relates to the manufacture field of chain, particularly relates to a kind of heavy duty welded chain.
Background technology
In oil extraction and mining equipment, chain is widely used, the work under bad environment of chain and bear heavy load, often occur inner plate and sleeve come off, the situation such as inner plate and outer plate excessive wear, cause equipment disorderly closedown, have a strong impact on production efficiency.
Summary of the invention
This utility model provides a kind of heavy duty welded chain, and it mainly solves the problem described in background technology, it is provided that a kind of compact conformation, it is simple to processing, coordinates firm and wear-resistant, service life length heavily loaded welded chain.
A kind of heavy duty welded chain that this utility model provides, it is composed in series by multiple chain units, each chain unit is by the carrier bar that bends, bearing pin and sleeve composition, it is provided with left carrier bar in it is characterized in that described press-bending carrier bar, middle connecting plate and right carrier bar, it is connected by described middle connecting plate between described left carrier bar with described right carrier bar, the inclined distribution of described middle connecting plate, described left carrier bar, described middle connecting plate and described right carrier bar are integration distribution, described sleeve is socketed in the outside of described bearing pin, the two ends of described sleeve are respectively equipped with described left carrier bar, the two ends of described bearing pin are respectively equipped with described right carrier bar.
As preferably: be matched in clearance between described sleeve and described bearing pin, it is matched in clearance between described bearing pin and described right carrier bar, is interference fit between described sleeve and described left carrier bar.
As preferably: the position that described sleeve and described left carrier bar contact uses welding to fix.
As preferably: one end of described bearing pin is provided with step, the other end of described bearing pin is provided with circular hole, and described circular hole is built with fastener.
This utility model provides a kind of heavy duty welded chain, taking left carrier bar, middle connecting plate and right carrier bar is integration distribution, this structure instead of traditional inner plate and the most independent structure of outer plate, this structure has the advantages that cooperation is firm, wear-resistant, it is welded and fixed again on the basis of interference fit between left carrier bar and sleeve so that coordinate more firm.This chain structure is compact, it is simple to processing, coordinates firm and wear-resistant, substantially increases chain in harsh environments and the service life in the case of bearing heavy load.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Labelling in figure: 1-press-bending carrier bar: 2-bearing pin: 3-sleeve: the left carrier bar of 4-fastener: 5-: the right carrier bar of 6-middle connecting plate: 7-: 8-step: 9-circular hole.
Detailed description of the invention
Understand for the ease of those of ordinary skill in the art and implement this utility model, and combining accompanying drawing the technical solution of the utility model is described in further detail.
nullEmbodiment: as shown in Figure 1，A kind of heavy duty welded chain of this example，It is composed in series by multiple chain units，Each chain unit is by the carrier bar that bends (1)、Bearing pin (2) and sleeve (3) composition，It is provided with left carrier bar (5) in it is characterized in that described press-bending carrier bar (1)、Middle connecting plate (6) and right carrier bar (7)，It is connected by described middle connecting plate (6) between described left carrier bar (5) with described right carrier bar (7)，Described middle connecting plate (6) inclined distribution，Described left carrier bar (5)、Described middle connecting plate (6) and described right carrier bar (7) are distributed in integration，Described sleeve (3) is socketed in the outside of described bearing pin (2)，The two ends of described sleeve (3) are respectively equipped with described left carrier bar (5)，The two ends of described bearing pin (2) are respectively equipped with described right carrier bar (7)，It is matched in clearance between described sleeve (3) and described bearing pin (2)，It is matched in clearance between described bearing pin (2) and described right carrier bar (7)，It is interference fit between described sleeve (3) and described left carrier bar (5)，The position that described sleeve (3) and described left carrier bar (5) contact uses welding to fix，One end of described bearing pin (2) is provided with step (8)，The other end of described bearing pin (2) is provided with circular hole (9)，Described circular hole (9) is built with fastener (4).
This utility model provides a kind of heavy duty welded chain, taking left carrier bar, middle connecting plate and right carrier bar is integration distribution, this structure instead of traditional inner plate and the most independent structure of outer plate, this structure has the advantages that cooperation is firm, wear-resistant, it is welded and fixed again on the basis of interference fit between left carrier bar and sleeve so that coordinate more firm.This chain structure is compact, it is simple to processing, coordinates firm and wear-resistant, substantially increases chain in harsh environments and the service life in the case of bearing heavy load.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and change or the modification made all are contained among the scope of the claims of the present utility model.
