Abstract
The utility model relates to the road-heading machinery for a coal mine channel, in particular to a traveling section of a roadheader, which solves the problems of the prior roadheader such as increased resistance caused by coal and rock invading into the inside of the traveling section. Two rows of double-head bolts are arranged on the traveling frame of the traveling section, and the traveling section is connected with a main body section through the two rows of double-head bolts. Coal baffles are arranged on both sides of support wheels arranged below the traveling frame, so that the traveling section is fully closed by the coal baffles to form a fully-closed structure; and tension wheels arranged at one end of the traveling frame adopt a chain wheel structure. The traveling section of the roadheader can greatly reduce the traveling resistance and improve the reliability of the roadheader.
Description
Technical field
The utility model relates to the coal mine roadway road heading machinery, is specially a kind of development machine running part.
Background technology
At present, big gun pick operation is adopted in tunnelling, is an arduous and dangerous job, and main cause is that the tunnel back warp often has gas to overflow, and meets naked light and blasts; Boom-type roadheader adopts creeper undercarriage, the device imperfection of its running part retaining coal, rock, and very easy entering such as coal, rock particle are caused tractive resistance, damage component.So, be starved of a kind of running part of working stability, improve the operating efficiency of driving, reduce operator's labour intensity.
The utility model content
The purpose of this utility model is to provide a kind of development machine running part, problems such as the device imperfection of the existing development machine running part retaining of solution coal, rock and bonding strength deficiency, this running part can reduce walking resistance significantly, improves reliability, reduces operator's working strength.
The technical solution of the utility model is:
A kind of development machine running part has walker, thrust wheel, regulating wheel, and two row's studs are installed on the walker of described running part, and running part is connected by two row's studs with body.
Described development machine running part, spillplate is equipped with in the thrust wheel both sides that are provided with below walker, and making running part is the spillplate full-closed structure.
Described development machine running part, the regulating wheel that is provided with at walker one end adopts chain sprocket structure.
The beneficial effects of the utility model are:
1, the running part of the utility model development machine is connected with two row's studs with body, increases bonding strength, improves reliability.
2, the running part of the utility model development machine adopts the spillplate full-closed structure, avoids foreign material such as stone to enter, and reduces walking resistance.
3, the running part regulating wheel of the utility model development machine adopts the chain wheel mode, increases stabilization of equipment performance.
Description of drawings
Fig. 1 is the utility model development machine running part structure chart.
Fig. 2 is the utility model development machine running part sectional structure chart.
Among the figure, 1 driving wheel; 2 walkers; 3 thrust wheels; 4 track assemblies; 5 regulating wheels; 6 studs; 7 spillplates; 8 bodies.
The specific embodiment
Shown in Fig. 1-2, the utility model development machine running part comprises driving wheel 1, walker 2, thrust wheel 3, track assembly 4, regulating wheel 5, stud 6, spillplate 7 etc., at walker 2 two ends driving wheel 1 is housed, regulating wheel 5, regulating wheel 5 adopts chain sprocket structure, thrust wheel 3 is housed below walker 2, driving wheel 1, regulating wheel 5, thrust wheel 3 outsourcing track assemblies 4, in the both sides of thrust wheel 3 spillplate 7 is housed, making running part is spillplate 7 full-closed structures, two row's studs 6 are installed on the walker 2, and running part is connected with body 8 usefulness two row's studs 6.
The course of work of the present utility model is as follows:
Running part drives track assembly 4 by driving wheel 1, regulating wheel 5 tensioned tracks assemblies 4, and thrust wheel 3 supports walker 2, and track assembly 4 rotation drive running parts advance or retreat.
