Abstract
The utility model relates to a connecting ring for a heavy-type double-side-chain type scrapping plate conveyor in order to resolve the problems that when the heavy-type double-side-chain type scrapping plate conveyor is produced at present, a needed large open type connecting ring lacks, is complex to manufacture and too high in cost. The connecting ring for the heavy-type double-side-chain type scrapping plate conveyor comprises a high-strength mining annular chain ring and a connecting plate, an alloy steel part with the material similar to the material of the annular chain ring is adopted and is forged to form the connecting plate, then the standard coarse-pitch annular chain ring is welded through a welding rod with the material similar to that of the annular chain ring, the residual stress after welding is eliminated in a heat processing mode, and the structure performance of metal material after welding is improved.
Description
Technical field
The utility model belongs to field of transport machinery, is specifically related to the bilateral chain scraper conveyer coupling link of a kind of heavy type, is mainly for the connection between the mining high-tensile round-link chain chain of the bilateral chain scraper conveyer of heavy type and scraper plate.
Background technology
At present, in bilateral chain scraper conveyer manufacturing, connecting mine high-tensile round-link chain chain and scraper plate generally use the open connecting ring of fine pith, and this open connecting ring is to adopt the die forging manufacture to form, and is a kind of distressed structure of standard round loop chain.Round-link chain one side straight flange disconnects from middle part, at round-link chain, on one side radially draws bipod in the center plane, bipod endways respectively zone zoom into rectangular structure, boring, be connected with scraper plate by bolt; Opposite side straight flange volume amplifies, and plays invigoration effect; Two semicircular ring structures keep, and guarantee and the chain good contact.But away from round-link chain chain link center, the arm of force is excessive due to the opening part of opening coupling link; Conveyer work split shed ring is under the effect of pulling force, and opening Easy open distortion, exceed chain nest size on drive sprocket and make that round-link chain skids, sideslip, and the conveyer et out of order is shut down.
According to MT/T 71 standards, specification is the coarse pitch open connecting ring more than 30 * 108 at φ, and domestic do not have special manufacturer to manufacture.Adopt the coarse pitch open connecting ring to customize, and domestic overwhelming majority factory processed all needs independent die sinking, has greatly increased conveyer and has manufactured the manufacturing cost of manufacturer, in the maintenance in user's later stage, buy spare part difficulty and the expense eighteenth of the twenty expensive, greatly affected production.
The utility model content
The coarse pitch open connecting ring that the utility model need be used when solving the heavy bilateral chain scraper conveyer of current production lacks type, manufacture complicated, the problem of high expensive, providing a kind of heavy type bilateral chain scraper conveyer coupling link, is to use for the bilateral chain scraper conveyer of heavy type the structure that standard high strength mining round link chain chain is connected with scraper plate.
the utility model has solved and has filled up technology and the Cost Problems of heavy bilateral chain scraper conveyer on heavy-duty is manufactured, the technical scheme that adopts is: the bilateral chain scraper conveyer coupling link of a kind of heavy type, comprise high-strength mining round-link chain chain link and connecting panel, adopt the alloy steel piece that material and selected round-link chain chain link material are close, through forging, be processed into connecting panel, then the round-link chain chain link of a standard coarse pitch is used the welding rod close with round-link chain chain link material to weld with it, after reusable heat process eliminates welding except unrelieved stress, improve the structure property of postwelding metal material.
The beneficial effects of the utility model are: with traditional open connecting ring, compare manufacture simple, easy to maintenance, can save higher die cost, manufacturing cost is lower, is more suitable for the Design and manufacture of the bilateral chain scraper conveyer of heavy coarse pitch.Coupling link of the present utility model organically is connected scraper plate, chain, in convey materials, played indispensable key role, for China's laying a good foundation in the production domesticization of the bilateral chain conveying machine equipment of heavy type, thereby break away from the situation by external import, intensive, high strength exploitation at Coal Industry simultaneously meets higher requirement, the important channel that greatly raise labour productivity, save investment, reduces production costs.
The accompanying drawing explanation
Fig. 1 is front elevation of the present utility model.
Fig. 2 is the B-B cross section view of Fig. 1.
Fig. 3 is axonometric drawing of the present utility model.
Fig. 4 is the scheme of installation of the utility model at the bilateral chain-and-flight conveyer of heavy type.
In figure, 1 is high-strength mining round-link chain chain link, and 2 is connecting panel, and 3 is scraper plate, and 4 is regular bolt, 5 is the standard flat gasket, and 6 is the standard spring washer, and 7 is the standard slotted nut, 8 is the standard openings pin, and 9 is standard sawtooth coupling link, and 10 is standard high strength mining round link chain chain.
The specific embodiment
In order more to be expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in following examples.
This coupling link is to choose the material alloy steel material consistent with the high-strength mining round-link chain, after forging, be processed into connecting panel 2, again high-strength mining round-link chain chain link 1 and connecting panel 2 are used the welding rod that material and round-link chain chain link material are approximate to weld, guarantee that annulus straight flange and edge are tangent.Post-weld heat treatment goes unrelieved stress, the processing through hole.During assembling, connecting panel 2 is connected to combination with scraper plate 3, high-strength mining round-link chain chain link 1 is connected by standard sawtooth coupling link 9 with standard high strength mining round link chain chain 10, notes making downstairs face and the sprocket periphery of coupling link tangent.
Conveyer is in when work, and drive sprocket drives chain movement, by coupling link of the present utility model, pulling force is passed to scraper plate, and promotes material and travel forward, thereby reaches the purpose of convey materials.
Claims (2)
1. bilateral chain scraper conveyer coupling link of heavy type, comprise high-strength mining round-link chain chain link and connecting panel, adopt the alloy steel piece that material and selected round-link chain chain link material are close, through forging, be processed into connecting panel, then the round-link chain chain link of a standard coarse pitch is used the welding rod close with round-link chain chain link material to weld with it, after reusable heat process eliminates welding except unrelieved stress, improve the structure property of postwelding metal material.
2. the bilateral chain scraper conveyer coupling link of a kind of heavy type according to claim 1, its feature part is: for the bilateral chain scraper conveyer of heavy type, use the structure that standard high strength mining round link chain chain is connected with scraper plate.
