Abstract
The utility model discloses a buckling chain connector of round link chain for a mine. The buckling chain connector comprises two half chain links (2) and a fixed pin (3). Each of the half chain links (2) is provided with a nose (1) and a sunken head (5) which are meshed with each other. The buckling chain connector is characterized in that meshed screw threads are arranged on the contact surfaces of the fixed pin (3) and the two half chain links (2); and 2 to 4 threaded holes meshed with a locking nut (4) are arranged in the lateral surface of the fixed pin (3). The buckling chain connector has strong strength and high positioning performance, can avoid relative dislocation in the using process; the central fixed pin cannot easily fall off and does not become loose and fall, so that the overall stability and reliability are greatly improved; moreover, the buckling chain connector is convenient to assemble and disassemble, and does not rotate when assembled and disassembled, so that the service life of the chain connector can be remarkably prolonged.
Description
Technical field
The utility model relates to a kind of conduction chain, is specifically related to a kind of circle chain of mine button chain ring.
Background technology
Circle chain of mine is by on the mine flight conveyer of various models; China's existing link circle chain of mine in use; Frog shape chain joint assembly; Usually lost efficacy, and whole assembly is become flexible and deviate from, and caused chain joint is broken off because of the violent friction of mechanical shock and generation such as the coal that delivered, spoil makes wherein individual part undue wear occur.Open type chain T-Ring commonly used in addition only tightens together opening part and scraper plate with a bolt; Because mechanical shock causes the nut anti-looseness structure of fastening effect all can not stop nut loosening by actv. with the frequent variations that receives tensile stress, this is the critical defect of open type chain T-Ring.Also have the flat chain T-Ring of a kind of annulus link serration, its spring pin that plays fixation receives transverse shearing force, easy deformation in chain ring work; Thereby cause the dismounting difficulty, and in the down-hole coal excavation process, need frequent dismounting, but can't load onto after taking apart sometimes; This is a defective intrinsic on its structure, and simultaneously, the flat chain ring of serration can not bear the curved power of bigger side direction; And discontinuity between tooth and the tooth; Under the effect of live load, produce slight crack easily and cause chain ring to damage, like this, it can only be used for the less conveyor chain of traffic capacity.
The utility model content
The purpose of the utility model is to existing above-mentioned deficiency, provide a kind of chain link effective, can repeated usage, the circle chain of mine button chain ring of convenient disassembly, good stability, long service life.
The purpose of the utility model realizes through following technological means: a kind of circle chain of mine button chain ring; Include two and half chain links and set pin; Described half chain link is provided with intermeshing plush copper, recessed head; The contact surface of said set pin and two and half chain links is provided with the ingear screw thread, also is provided with on the side of said set pin and 2-4 tapped bore of rotating-proof nut ingear.
Positive six rib holes in the axis of said set pin is provided with.
Compared with prior art the utlity model has following tangible advantage: this circle chain of mine button chain ring is installed on the mine flight conveyer and uses; Characteristics with intensity height, in light weight, easy accessibility; No matter be installed on level attitude or the upright position; All can replace the coupling member of existing various circle chain of mine, be used for the mine flight conveyer of various models smoothly through the sprocket wheel of slat conveyer.As connecting flight chain in the slat conveyer, its intensity is big, does not produce relative dislocation in the use simultaneously; Polarization is good, center fixation pin difficult drop-off, not loose stability and the reliability that does not fall, greatly improved complete machine; Easy accessibility in addition, trend without spin, not rotation during installing/dismounting; Very convenient, as can obviously to improve chain ring service life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1-plush copper, 2-half chain link, 3-set pin, 4-rotating-proof nut, the recessed head of 5-.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is done further to describe in detail:
A kind of circle chain of mine button chain ring as shown in Figure 1; Include two and half chain links 2 and set pin 3; Described half chain link 2 is provided with intermeshing plush copper 1, recessed 5; The contact surface of said set pin 3 and two and half chain links 2 is provided with the ingear screw thread, also is provided with on the side of said set pin 3 and rotating-proof nut 4 an ingear 2-4 tapped bore.Be provided with like this; This circle chain of mine button chain ring can be fixed as a chain ring with two and half chain links 2 firmly through intermeshing plush copper 1, recessed 5; And then screw in set pin 3, when treating that set pin 3 and two and half chain links 2 are rotated into a plane, screw in 2 rotating-proof nuts 4 again; So just can better place coming off of set pin 3, better fixing two and half chain links 2.
Positive six rib holes in the axis of said set pin 3 is provided with.Setting like this, this circle chain of mine button chain ring can screw in or back-out through hexagonal wrench when screwing in set pin 3 sooner, more easily, thus dismounting faster and more easily.
In a word, the utility model provide a kind of chain link effective, can repeated usage, the circle chain of mine button chain ring of convenient disassembly, good stability, long service life.The above; Be merely a part of specific embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
Claims (2)
1. circle chain of mine button chain ring; Include two and half chain links (2) and set pin (3); Described half chain link (2) is provided with intermeshing plush copper (1), recessed head (5); It is characterized in that: said set pin (3) is provided with the ingear screw thread with the contact surface of two and half chain links (2), also is provided with on the side of said set pin (3) and rotating-proof nut (a 4) ingear 2-4 tapped bore.
2. a kind of circle chain of mine button chain ring according to claim 1 is characterized in that: positive six rib holes in the axis of said set pin (3) is provided with.
