Description
Technical field
The present invention relates to a kind of loader and assembly and disassembly methods thereof, specifically, relate to a kind of new type mining backhoe loader and assembly and disassembly methods thereof, belong to mining equipment technical field.
Background technology
Along with we increase day by day to the demand of producing, build, backhoe loader becomes the indispensable instruments in aspect such as electric power, water conservancy, petrochemical complex, building materials, coal, metallurgical mine, communications and transportation, agricultural engineering, town and country construction, port construction, airport and national defense construction.Common backhoe loader divides according to purposes, can be divided into general backhoe loader, mine backhoe loader, backhoe loader peculiar to vessel, the classification that extraordinary backhoe loader etc. are different.And along with the continuous increase of country to demand for energy, also more and more higher to the requirement of mine producing coal efficiency, so the growth momentum of mine excavator is also more and swifter and more violent.
The sixties in 20th century, backhoe loader has experienced the development chassis special phase, structural behaviour is improved after date technology important breakthrough again, adopts articulated bucket loader; Its scraper bowl turns to front vehicle frame, and turn radius is little, maneuverability, is applicable to the operation of narrow place, is formally used to mine operation.Mining loader for mine is mainly used in space-constrained hole and adopts rubble earth material after the explosion of the various mines such as the phosphorus ore of operation, iron ore, copper mine, gold mine, silver ore, plumbous zinc ore, coal mine roadway, water power, tunnel engineering and gather and carry construction entrucking.
Conventional mining loader for mine is mainly comprised of chassis assembly, excavation assembly, delivery assembly three great institutions and hydraulic pressure, electric two large systems.By coordination and the cooperation of each several part, finally by hydraulic pressure, electric power element and mechanical transmission mechanism, realized the action of defined, complete each operation process.The features such as wherein four wheel drive has soil fertility, and propelling thrust is strong; Excavate acquisition function and completed by manipulator, manipulator has excavation, semi-girder, charging, discharging performance, and the second hold-down arm can rise, decline, and left and right revolution is excavated the manipulation of collection by all-hydraulic control; Carry, entrucking performance is completed by conveyer system, and its carriage is controlled lifting by hydraulic actuating cylinder, when carriage declines, front-wheel can be propped, before carriage, material receiving port and ore contact surface are tightr simultaneously, and during work, stability is stronger, can gather bulk cargo, smooth location simultaneously; Hydraulic efficiency pressure system is by fluid motor-driven front and back wheel, HM Hydraulic Motor have move ahead, retreat, three kinds of performances of self-actuating brake.
But due to the limitation of prior art, contriver finds that the mining loader for mine providing has on the market run into following technical matters when carrying out work:
1. different according to the tonnage of excavating machine, can be divided into 10 tons with the middle-size and small-size excavating machine of interior mini-excavator, 10-20 ton, the medium-sized excavator of 20-30 ton and 30 tons of above large excavators, the in general employing of the chassis portion in the running gear of large excavator one-piece construction.In actual use, find, mining loader for mine has oad, the feature that volume and weight is larger, wherein the weight of chassis portion often accounts for the more than 30% of complete machine weight, its at mine down-hole compared with long distance transportation or when mine section is worked, cannot in tunnel, work or walk, turn, stopped up on the contrary tunnel, hindered normal production, and because current chassis of dredging machine part generally adopts one-piece construction, so-called one-piece construction refers to that the traveling gear of both sides being installed by pedrail mechanism and middle sole (crossbeam) are connected for integral type, be sole and left and right traveling gear weld together, thereby cannot regulate the distance between sole and left and right traveling gear, also thereby sole and left and right traveling gear cannot be decomposed to the decomposition weight that comes, thereby tend to while causing large-scale or ultra-large type excavating machine to utilize Automobile Transportation overweight, super wide or superelevation, cannot meet the requirement of transportation, and there is larger potential safety hazard.So Chinese invention patent application CN101974924A discloses a kind of retractable chassis structure for excavating machine, by the improvement to chassis structure, make the chassis conveniently telescopic of excavating machine, meet the requirement of transportation.But the improvement of this structure has only been changed to its size, and chassis portion or an integral body, do not solve the overweight problem in chassis, so before going down into a mine also need chassis of dredging machine to dismantle, after arriving driving surface, re-start general assembly.Generally chassis portion can only be dismantled as two parts, also may be excessive because of chassis portion in disassembled for transport process (original structure restriction cannot further be decomposed it), cause that one piece is overweight or excessive cannot transport, assemble.China patent application CN102235167A discloses a kind of excavating loader for coal mine, comprises the Rack Body being comprised of left fixed mount, underframe and right fixed mount and is fixedly assembled in backhoe mechanism, scraping transporter, left body, right body, left traveling gear and the right traveling gear on Rack Body; Its left traveling gear and right traveling gear are fixedly connected on respectively the outside of left fixed mount and right fixed mount, and left body and right body are fixedly connected on respectively the top of left fixed mount and right fixed mount outside, left traveling gear and right traveling gear.Although the chassis portion of this backhoe loader is small volume, assemblnig structure, its chassis part is many, complex structure, and dismounting efficiency is low, is not easy to transhipment, so that wastes work-hours.
2. traditional mining loader for mine is when underground work, must move in fact time with actual condition, generally all need in dedicated track, could walk, once run into the obstacles such as rock in dedicated track, loader cannot move ahead.Chinese utility model patent CN201428455Y discloses a kind of mining loader for mine crawler travel and shovel board combination mechanism, adopt crawler travel without track, action is convenient, can arrive the more complicated local operation of ground condition, shovel board can be rooted out the obstacle dropping before crawler belt, makes crawler travel more smooth, if but while running into the large obstacles such as rock, shovel board on loader cannot be rooted out obstacle, needs to increase auxiliary miner and could solve problems.In order to save operation cost, reduce artificial expenditure, Chinese utility model patent CN201447725U discloses a kind of Novel push plate combined mechanism of mining loader for mine, not only can be bulldozed nuts around, can also push away to remove and drop on the obstacle that crawler belt two is taken up the place ahead, make crawler travel more smooth.But, because of ore deposit underground working severe, tunnel has certain slope, the inside is uneven, if run into the obstacle that push pedal cannot be bulldozed, the traveling gear of mining loader for mine still can, because outstanding rock is greater than guide wheel radius, surpass the power-handling capability of HM Hydraulic Motor, cause traveling gear resistance dead, it cannot be advanced or retreat.
3. when mining loader for mine is when driving surface is worked, often run into and also have larger sillar because of place driving surface after big gun pick, surpass the equipment turn-over capacity of mining loader for mine or manually cannot be broken, now can only after second-time breakage, transport, the method affects the progress of work, labor intensive material resources, and impact safety in production.Chinese utility model patent CN202850076U and Chinese invention patent application CN103388346A disclose a kind of mining loader for mine that is provided with excavating gear and breaker, its breaker is all connected on excavating gear, can be because of the work that influences each other more greatly of its volume during borehole operation.And for example Chinese utility model patent CN202913435U discloses a kind of colliery crushing and loading roadway repairer, quartering hammer is installed on to forearm inside, while needing fragmentation, as long as scraper bowl is shunk and is put in place, drill steel is installed in quartering hammer, just can carry out fragmentation, underground labour's labour intensity and the production time changing the outfit have greatly been alleviated, but this invention makes the part-structure weight of digging mechanism excessive, its oil cylinder loss aggravation, easily make oil cylinder break down, and greatly affected continuous firing ability and its accuracy rate of equipment; Because quartering hammer weight is more than 200kg, very high to the bearing pin between little, large arm and plain bearing requirement of strength again, the bearing pin that prior art provides and this kind of intensity of plain bearing out of reach,, there is very large potential safety hazard in easy fracture.
4. in China < < safety regulations in coal mine > >, stipulate " the minimum free height of arched tunnel height is 2000mm ", and the height of domestic existing mining loader for mine travelling position is all not less than 2200mm, and the every increase of arched tunnel height 200mm/m, mine owner will drop into 5000 yuan/m (tunnel length) more, in order to save financial cost, in each mine, the minimum free height of arched tunnel will be as far as possible little meeting under the prerequisite of national safety standard, generally be approximately 2m * 2m, to reduce expenditure, therefore, develop highly as far as possible little mining loader for mine to cost-saving, cut the waste necessary.
