Abstract
The utility model relates to a split cast-welded coal conveying groove, which relates to a special part of a scraper conveyer of an underground working face of a coal mine, and comprises a frame bottom groove with a peripheral closed structure and an upper groove which can be separated, wherein, the upper groove and the frame bottom groove are combined into a whole by a fastener. The utility model can be applied to the matching requirements of a fully mechanized mining face under various geological conditions. The frame bottom groove and the upper groove are all of cast-welded type structures. The basic cross section is disclosed in the specification. Because the upper groove can be separated, and therefore, the service life of the utility model can be extended by replacing the upper groove, an observation hole on a middle plate of the frame bottom groove can be used for examining and treating the bottom chain failure by separating the upper groove.
Description
The utility model split cast-welded coal chute relates to the coal mine equipment field, is colliery mining face under mine drag conveyor coal chute device.
Colliery mining face under mine drag conveyor relies on scraper chain transportation coal, coal chute will be not only because its limit function will carry scraper chain (cochain) and backhaul scraper chain (following chain) to be limited in the coal chute framework, and because location, the draw bail of coal chute two ends make adjacent coal chute produce corner on vertical and horizontal direction, thereby make the conveyer pars intermedia bending of forming by a considerable amount of coal chutes and the requirement that the adaptation continuous mechanized is mined.The structural reliability of coal chute is conspicuous to the life-span influence of whole drag conveyor.
Early stage coal chute is because material thickness can not increase, and the setting element cross section is less, and coal chute is made up of basic intermediate channel, plug-in ramp plate (or spillplate), and plug-in ramp plate spillplate and intermediate channel connect as one with bolt.Production practices prove that this structure has been difficult to guarantee the life requirements of high yield work plane to conveyer.
In recent years,, prolong the application life of coal chute, once had several structural concepts to put into practice for improving the coal amount of crossing of coal chute.Basic ideas all are based on the framework bathtub construction, groove on stack or easily changeable intermediate channel of suit or the C type, the life-span of attempting to prolong with this complete machine.Number of patent application 90201833.7 " drag conveyor coal chute framework " has proposed
The shape frame construction, the conventional intermediate channel of inside groove suit.Intermediate channel is mainly born the operating normal wear framework of equipment and is born other external force.Number of patent application 95202236.2 " interlude cast frame and C shape groove ", this structure bottom framework is a single-casting, C type groove is fixed on the framework top by alignment pin.This open type framework can be laid on scraper chain on the chain road, the end easily.
These two kinds of structures all in the coal life-span excessively of making great efforts to improve coal chute, make coal chute be in good stress.But can see after this structure analyzed that the open type bottom framework is because the restriction of base plate thickness, its rigidity and intensity will be affected; Distortion during framework uses not instrument causes maintenance, dismounting difficulty, also influences its life-span.
The purpose of this utility model is the split cast-welded coal chute that proposes a kind of new closed frame formula structure.It not only has separates the characteristics that go up groove, and has stable tower structure, has strengthened the intensity and the non-deformability of kerve, helps the raising in coal chute life-span.
The purpose of this utility model is achieved in that groove and kerve adopt threaded fastener to be combined into one, and last groove and kerve are separable.Last groove is welded as a whole by two casting ledges and middle plate, and kerve is cast ledges and a middle plate and a back cover plate by two and is welded as a whole, and constitutes a closed frame.The casting ledge has protruding (or recessed) termination to the neutralization location, has to hang the connection seat that hangs, embeds long ring or dumbbell pin.
The utility model, can be changed when last groove life termination or damage easily because last groove and kerve are separable, has improved the recycling rate of waterused of kerve, has reduced the equipment use cost.Because kerve is the frame construction of a sealing, strengthen the rigidity of structure of kerve again, strengthened the intensity and the non-deformability of kerve, prolonged the application life of whole coal chute.Owing to plate in the kerve is established the inspection window, help installing and troubleshooting simultaneously.
The concrete structure of utility model is provided by following example and accompanying drawing.
Below in conjunction with details and the working condition of four accompanying drawings detailed descriptions according to the concrete device that the utility model proposes.
Fig. 1 is the structural representation according to the split cast-welded coal chute device that the utility model proposes.
Fig. 2 is the last channel section figure according to the split cast-welded coal chute device that the utility model proposes.
Fig. 3 is the kerve profile according to the split cast-welded coal chute device that the utility model proposes.
Fig. 4 is a kind of application pattern according to the split cast-welded coal chute device that the utility model proposes.
By above accompanying drawing, concrete structure of the present utility model is:
This device is gone up groove by one and is 1. 2. formed with a kerve, by bolt 3., packing ring 4., 5. nut be connected as one, and can carry out dismounting easily.
Last groove by two casting ledges that have a scraper plate gathering sill wing 6. with middle plate 7. assembly welding become open trough.But limiting scraper moves in groove, and the cargos such as coal that groove is piled up move together in company with scraper chain, realizes the transport capacity of coal chute.
Kerve by two the casting ledges 8., middle plate 9. with back cover plate 10. assembly welding become a closed framework.The propelling of connection seat and coal chute, draw move relevant.In plate have the inspection window on 9., middle plate 9. and back cover plate return chain space for scraper chain between 10..
Coal chute is placed on the work plane base plate, makes adjacent coal chute be connected into the flexible coal handling system of long line formula by long ring.Kerve tightly is not the installation basis of going up groove, is the contact tie of work plane miscellaneous equipment (as support, coal-winning machine etc.) yet.Coal-winning machine straddles on the kerve, and sideslip boots slide in leading on the shovel board ledge, and opposite side traction guiding device is along the alligator guide rail operation of baffle plate side channel group.Coal chute will bear the deadweight of coal-winning machine, bear the cut load and the traction load of coal mining machine roller.The push-and-pull of support and coal chute moves the ear seat and links, and coal chute will bear the pushing and sliding power of support and the power of trying to stop people from fighting each other, and by the asynchronous push-and-pull operation of coal chute and support, realizes the propelling of coal chute and support, guarantees the continuity of stoping operation.
Therefore, the rigidity of structure of kerve, intensity and abrasion resistance directly affect the life-span of coal chute.Because kerve is to be a closed framework by middle plate, back cover plate and two casting ledge assembly weldings, so the geometric cross section of kerve is stronger than the open type frame stiffness of plate in the nothing, is beneficial to the raising in coal chute life-span.
