Description
Technical field
The utility model relates to a kind of development machine, particularly a kind of mine that is applicable to, tunnel, the large gradient roadheader of colliery and the operation of correlation engineering heavy grade.
Background technology
The digging underworkings is the necessary previous work of coal mine operation, is the most frequently used operating type in current colliery and accomplish this operation with development machine.But this operation general requirements tunnel gradient is about ± 16 °; Exceed the common development machine of this scope and in tunneling process, be difficult to realize operation; And cause the slide car easily or overturn dangerous; Have to adopt the big gun pick in this case, yet big gun pick operation is not only dangerous high, and loses time and lot of manpower and material resources.
Summary of the invention
The purpose of the utility model provides a kind of development machine that is specifically designed to the heavy grade tunnel, when being used to solve the tunnel gradient greater than ± 16 °, and the problem that common development machine can't be worked.Danger and the time waste of having avoided big gun pick operation to bring, and reduce the coal resources waste that the big gun pick causes and increase a series of problems such as working strength.
The purpose of the utility model is achieved in that and comprises body, running gear, cutting means, shovel panel assembly; It is characterized in that; Running gear is fastened on the body through bolt; Cutting means, shovel panel assembly are connected with body through bearing pin with a shipping unit, and fuel tank, top support, back support and protective cover are through being bolted on the body.Body is provided with and pushes up support, and the top is supported the upper end and is provided with 3 wedge angles, and wedge angle can insert the tunnel end face, and the frictional force of increase and tunnel end face prevents that effectively body from gliding, and increases the stability of equipment.Cutting means is provided with the rewinding of the auxiliary shovel of rewinding plate plate; Reductor in the cutting means is provided with oil scavenge pump, realizes that self-loopa is lubricated; Telescopic arm in the cutting means is equipped with vent hood, and changes the pouring orifice position, fundamentally solves common in the past development machine leakage of oil problem.Running gear is provided with the earth anchor oil cylinder, and " eight " font creeper tread and crawler belt thorn are increased, and crawler belt thorn spacing is encrypted, and the motor driving moment increases to 80KN.M, for the heavy grade walking provides reliable power.One shipping unit adopts the double-stranded scraping board type structure in limit, and scraper plate is increased, encrypted, and prevents that effectively material falls problem after rise in the scraper plate.In order to prevent fuel tank emptying phenomenon in the climb and fall process, strengthen volume of fuel tank, oil suction worry and the oil return filter filter core that extends simultaneously, the moisture absorption mode is adopted in empty filter, can the moisture absorption in the fuel tank be played dry effect.
The beneficial effect of the utility model is:
1, realizes the development machine tunnel gradient ± 25 ° of operate as normal that scope is interior, improved operational security, saved subsidiary operation time, made flexible operation reliable, solved the situation that heavy grade adopts big gun to dig.
2, good reliability, maintainable and safe.
3, combine mine actual conditions and designing, so practicality is high.

Among the figure, 1 cutting means; 2 shovel panel assemblies; 3 tops are supported; 4 bodies; 5 running gears; 6 protective covers; 7 fuel tanks; 8 backs are supported; 9 one shipping units; 10 rewinding plates; 11 telescopic arms; 12 vent hoods; 13 oil scavenge pumps; 14 chain and sprocket driving devices; 15 earth anchor oil cylinders; 16 creeper treads; 17 running motors; 18 scraper chains.
The specific embodiment
Can know like Fig. 1-4; Each installs independent operation; Be connected with body through bearing pin or bolt, cutting means 1, shovel panel assembly 2 and back are supported 8 and are connected with body 4 through bearing pin, and top support 3, running gear 5, protective cover 6, fuel tank 7 and a shipping unit 9 pass through high-strength bolt and connect with body 4; Wherein rewinding plate 10, cutting arm 11, vent hood 12, oil scavenge pump 13 and chain and sprocket driving device 14 have been formed cutting means 1 through bolt and splined; Earth anchor oil cylinder 15, creeper tread 16 and running motor 17 have been formed running gear 5 through bearing pin and Bolt Connection, and creeper tread 16 is formed by connecting through bearing pin the splayed caterpillar teeth.Caterpillar teeth height 40-50mm.Scraper chain is installed on the shipping unit 9 through sprocket wheel.
When working in the heavy grade tunnel, 80KN.M running motor 17, creeper tread 16 caterpillar teeth are increased encryption, and reliable power and climbing capacity are provided, the earth anchor oil cylinder 15 auxiliary body slide cars of climbing and having prevented when roadway floor is loosening, to cause.The top is supported 3 upper ends and is provided with 3 wedge angles, and wedge angle can insert the tunnel end face, and the frictional force of increase and tunnel end face prevents that effectively body from gliding, and increases the stability of equipment.Rewinding plate 10 is installed on the cutting means 1, and auxiliary shovel panel assembly 2 gives mass transport the scraper chain 18 employing limits in one shipping unit, 9, one shipping units 9 double-stranded scraping board type structure, and the spacing between scraper plate and the scraper plate is encrypted, and concrete spacing is 300-384mm.Prevent that effectively material falls problem after rise in the scraper plate, guaranteed the transportation of material.Because heavy grade when work, cutting means 1 middle (center) bearing and reductor lubricated most important, thus changed the position of oil filler point in the telescopic arm 11, and increased vent hood, solved the ubiquitous oil leakage phenomenon of development machine in the past.Oil scavenge pump and chain and sprocket driving device are housed on the reductor.Oil scavenge pump 13 has realized that with chain and sprocket driving device 14 self-loopa of reductor is lubricated, make cutting means can be at the elevation angle 70 ° with the 45 ° of scopes in the angle of depression in operate as normal.Fuel tank 7 has increased volume, oil suction worry and the oil return filter filter core that extends simultaneously, and the moisture absorption mode is adopted in empty filter, can the moisture absorption in the fuel tank be played dry effect, for heavy grade work provides reliable fuel feeding guarantee.
