Description
Technical field
The present invention relates to a kind of traction walking mechanism, specifically is a kind of traction walking mechanism of drum shearer, belongs to the coal mine machinery technical field.
Background technology
According to national coal storage total amount; Thin very extensive in China's distribution with ultra-thin coal seam; There is more than 80 office to compose in 95 the emphasis mineral bureaus in the whole nation and deposit thin and ultra-thin coal seam; State-owned emphasis colliery, the whole nation is thinner than 25.29 hundred million tons of ultra-thin coal seam reserves, mainly is drum shearer for thin employed equipment with the ultra-thin coal seam exploitation in the industry at present.Drum shearer mainly is tractive force to be provided and to be transferred to walking mechanism via gear by haulage gear to drive whole device motion in the course of the work.But because environmental limit in the work; In the situation of thin and ultra-thin coal seam high inclination-angle; Because machine height is restricted, appear as through regular meeting and to guarantee the strength of gear teeth and tractive force phenomenon not enough and that cause the strength of gear teeth to be damaged inadequately owing to tractive force is excessive, influenced and installed normal service efficiency; Increase the exploitation difficulty, thereby reduced the mechanization degree of high inclination-angle ultra-thin coal seam.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of traction walking mechanism of drum shearer, strengthens the strength of gear teeth, strengthens tractive force, guarantees the service efficiency of drum shearer, improves the mechanization degree of high inclination-angle ultra-thin coal seam.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of traction walking mechanism of drum shearer, form by tractive unit and running part; Tractive unit is connected through bolt with running part, and tractive unit comprises and lead one, lead two, motor, lead three, lead four, lead five, planetary mechanism and lead six that running part comprises walking axis; Also comprise shunt shaft, power transmission shaft and interflow axle, shunt shaft is two, is arranged in the tractive unit; Left end is symmetricly set on and leads six both sides, through the gear on the axle with lead six gears engaged on the axle, the right-hand member spline is connected through spline housing with power transmission shaft left end spline; The interflow axle is two, is arranged in the running part, and the left end spline is connected through spline housing with power transmission shaft right-hand member spline; Right-hand member is symmetricly set on the walking axis both sides, through the gears engaged on gear on the axle and the walking axis axle.
The present invention is provided with two shunt shafts in the traction walking mechanism of drum shearer; Motor is through leading one, lead two, lead three, lead four, leading five; Planetary mechanism transfers a torque to and leads six, leads six and branches to shunt shaft realization power dividing; Shunt shaft transfers a torque to two interflow axles in the running part through power transmission shaft, and the interflow axle collaborates power to walking axis, and drives whole device motion by walking axis.In the whole transmission course; Owing to be provided with two shunt shafts, power transmission shaft and interflow axle reduce single gear holding capacity; And increased the strength of gear teeth; And guaranteeing further to have improved tractive force under the situation of the strength of gear teeth, thus guaranteed that drum shearer normally uses in the situation of thin and ultra-thin coal seam high inclination-angle, further improved the mechanization degree of high inclination-angle ultra-thin coal seam.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1: to achieve these goals, the technical scheme that the present invention adopts is: a kind of traction walking mechanism of drum shearer, form by tractive unit and running part; Tractive unit is connected through bolt with running part, and tractive unit comprises and lead one 1, lead two 2, motor 3, lead three 4, lead four 5, lead five 6, planetary mechanism 7 and lead six 8 that running part comprises walking axis 13; Also comprise shunt shaft 9, power transmission shaft 10 and interflow axle 12, shunt shaft 9 is two, is arranged in the tractive unit; Left end is symmetricly set on and leads six 8 both sides; Through the gear on the axle with lead the gears engaged on six 8, the right-hand member spline is connected through spline housing 11 with power transmission shaft 10 left end splines, collaborating spools 12 is two; Be arranged in the running part 13; The left end spline is connected through spline housing with power transmission shaft 10 right-hand member splines, and right-hand member is symmetricly set on walking axis 13 both sides, through the gears engaged on 13 of the gear on the axle and the walking axis.In order to ensure being connected between tractive unit and the running part firm, adopt high-intensity hydraulic bolt to connect.
Under the condition of work of thin and ultra-thin coal seam high inclination-angle; Drum shearer is in the course of work; By the traction walking mechanism in motor 3 through leading one 1, lead two 2, lead three 4, lead four 5, leading five 6; Planetary mechanism 7 transfers a torque to and leads six 8, lead and branch to shunt shaft 9 for six 8 and realize power dividings; Shunt shaft 9 transfers a torque in the running part two interflow axles 12 through power transmission shaft 10, and interflow axle 12 collaborates power to walking axis 13, and drives whole device motion by walking axis 13.
In the whole transmission course; Owing to be provided with two shunt shafts 9, power transmission shaft 10 and interflow axle 12 reduce single gear holding capacity; And increased the strength of gear teeth; And guaranteeing further to have improved tractive force under the situation of the strength of gear teeth, thus guaranteed that drum shearer normally uses in the situation of thin and ultra-thin coal seam high inclination-angle, further improved the mechanization degree of high inclination-angle ultra-thin coal seam.
