Abstract
The utility model relates to a digging mechanism for a coal mine laneway, in particular to a heavy gradient digging machine which can work stably and solve the problems such as high fatalness, waste of time and increased workload for changing the angle of laneway for gun digging. The digging machine can work in a heavier gradient laneway, change the case that gun digging is adopted on heavy gradient laneway in the past, greatly improve working efficiency and ensure security guarantee to the labourers, the gradeability of which is from minus twenty-five degrees to plus eighteen degrees. A walking part is designed for the digging machine, which increases climbing driving force; a top support and both sides of a back support of a body are supported on the heavy gradient laneway, which increases the stability of the machine body while working; an anti-skidding creeper tread is adopted at the walking part and the anti-skidding treatment of the rear support legs of the back support can prevent the machine body from falling down; an upper limited device of the back support can ensure the driving device of a first conveying part does not to hit the laneway directly and damage the driving motor, even when the walking route of the digging machine deflects; a middle double chain scraper of the first conveying part is heightened, which ensures the conveying effect of materials.
Description
Technical field
The utility model relates to the coal mine roadway road heading machinery, is specially a kind of large gradient roadheader that can be implemented in the steady operation in heavy grade tunnel.
Background technology
At present, the tunnelling machine gradient is generally ± 16 ° in, when the tunnel gradient went beyond the scope, method commonly used was exactly the big gun pick, not only danger is very high in big gun pick operation, and development machine stops operation, and work plane is carried out the big gun pick cause the plenty of time waste; Especially some special operation condition (as face below bridge, building time) is forbidden the big gun pick again, can only change the tunnel angle in this case, so handling has on the one hand increased workload, has reduced the exploited length in tunnel simultaneously, has caused the waste of a large amount of coal resources.
The utility model content
The large gradient roadheader that provides a kind of climbing capacity stronger is provided the purpose of this utility model, solve the dangerous height of big gun pick operation, lose time and change the problems such as workload increase that the tunnel angle is brought, this development machine can be operated in the tunnel with heavy gradient (25 °～+ 18 °), change the situation of the big gun of heavy grade tunnel employing in the past pick, greatly improved operating efficiency, and given labourer with safety assurance.
The technical solution of the utility model is:
Large gradient roadheader has cutting units, running part, back support, Department of Transportation, and the top of described development machine is equipped with the top that can withstand on the top and is supported; The hinged respectively anti-skidding oil cylinder of traction that withstands on the both sides, tunnel in both sides is supported in described back, draws anti-skidding oil cylinder and supports the together support body with the top; First Department of Transportation of development machine adopts double center chain scraping board type structure; Described back is supported and is provided with stopping means; Described running part adopts the skid track plate.
The anti-skidding oil cylinder of described traction place increases auxiliary hitch.
The supporting leg wearing plate that described back is supported adopts the anti-skid structure of bottom band wedge angle.
Described skid track plate is for having protruding anti-skid structure with ground contact portion.
The walking driving force must be enough when 1, the development machine of working in the heavy grade tunnel at first was climbing, the reinforced running part of the special design of the utility model development machine, the motor driving moment can reach 80kNm, and work provides enough driving moments in the heavy grade tunnel for development machine.
2, development machine when the tunnel gradient is big, must cause body to glide because fuselage weighs tens tons, and the utility model development machine adopts following measure to reach the purpose that prevents that body from gliding:
(1) the body design has the top to support, and when the tunnel gradient was big, the top support cylinder stretched out, and withstands on the top, tunnel, has increased organism stability;
(2) hinged two tractions in both sides, anti-skidding oil cylinder are supported in the back, and two oil cylinders stretch out and withstand on the both sides, tunnel, can support with the body top and play the effect of supporting body simultaneously; Perhaps can on the support cylinder of back, increase auxiliary hitch, make the development machine climbing lighter;
(3) running part skid track plate, the supporting leg that the back is supported is designed to anti-skid structure, body downslide in the time of can preventing all that development machine from work in the heavy grade tunnel.
When 3, the tunnel gradient was big, during the first Department of Transportation transported material, material may drop in scraper plate, first Department of Transportation of the utility model development machine adopts double center chain scraping board type structure, scraper plate is increased, encrypted, prevented the material falling, guarantee the material transportation when working in the heavy grade tunnel.
When 4, the tunnel gradient was big, the development machine track route occurred unavoidably than large deviation, was installed on the stopping means that supports the back and can prevents that machine from bumping against the both sides, tunnel and damaging motor.
The beneficial effects of the utility model are:
But the on-line operation of the utility model heavy grade tunnelling machine is in heavy grade tunnel (25 °～+ 18 °), direct machine pick and without the big gun pick when guaranteeing that the tunnel gradient is big has reduced the danger of work widely and has improved operating efficiency, reduced the waste of coal resources.
