Abstract
The utility model relates to an improved low coal seam coal-winning machine electrical tow attachment which belongs to the technical field of coal mine coal mining equipment. A technical problem to be solved is to provide a coal-winning machine electrical tow attachment which has the large transmission strength of a traction transmission part, low failure rate and small size and is fit for using at the low coal seam. In technical proposal, a traction part of the coal-winning machine electrical tow attachment consists of the traction transmission part, a hydraulic turning-up and hydraulic braking system and an electric control part; the traction transmission part is provided with a pulling motor which is traction power. The improvement cmprises: the traction transmission part is also provided with a secondary transmission spur gear and a three-ring reducer which mesh each other and are a middle shaft set and an output shaft set; the secondary transmission spur gear is respectively connected with an output end of the pulling motor and an input end of the three-ring reducer; and the output end of the three-ring reducer is connected with a driving wheel.
Description
Technical field
The utility model relates to the outer live haulage shearer of a kind of girdle machine, belongs to the coal mining equipment technical field.
Background technology
At present, widely used low seam mining machinery has two types of hydraulic haulage and airborne electric tractions, wherein airborne electrical haulage shearer complete machine mainly by tractive unit, left and right sides cutting units, cylinder, cooling spray system, drag cable unit etc. to form.Complete machine is bearing on the intermediate channel of transporter by four guide slip shoes of rib side and old man's side respectively, brute force engagement by Cycloidal Wheel in the walking axle group that traction electric machine drove and pin row, under the situation about leading with the guide slip shoe that is contained on the tractive unit, to realize the traction walking of coal-winning machine along the transporter direction, simultaneously two cylinders of left and right sides rocking arm also are rotated under the driving of cutting motor, thereby finish the coal breakage of coal-face and coaling.
Tractive unit mainly contains the traction driving section, and hydraulic pressure is heightened and brake fluid system, and electrical control division is grouped into.The traction electric machine of traction driving section is imported power, slows down through the two-stage planetary mechanism, gives driving wheel with transmission of power, and driving wheel drives Cycloidal Wheel and rotates, and walks on transporter thereby Cycloidal Wheel and transporter pin rail gear motion drive coal-winning machine.
Find at work, the transmission intensity of this two-stage planetary gear speed reducing mechanism is little, fault rate is high, also has bulky shortcoming simultaneously, be not suitable for using under little in the low seam mining machinery space, as the to walk inclement condition situation, have and carry out improved necessity, make coal-winning machine adapt to the environment that girdle is mined more, and improve the coal-winning machine operating efficiency.
Summary of the invention
The improved low seam mining machinery electric traction device that technical problem to be solved in the utility model provided and a kind ofly draw that driving section transmission intensity is big, fault rate is low, volume is little, was adapted at that the low seam mining machinery space is little, use under the situation of walking inclement condition.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved low seam mining machinery electric traction device, its tractive unit is by the traction driving section, hydraulic pressure is heightened and brake fluid system, electrical control division is grouped into, it is traction power that there is traction electric machine the traction driving section, its improvements are, the traction driving section also has intermeshing secondary transmission spur gear and three-ring speed reducer, be jackshaft group and output shaft group, secondary transmission spur gear is connected with the output of traction electric machine and the input of three-ring speed reducer respectively, and the output of three-ring speed reducer is connected with driving wheel.
Above-mentioned improved low seam mining machinery electric traction device, the RHVC of tractive unit are placed in the interior active station of crossheading.
Adopt the low seam mining machinery electric traction device of this traction drive mechanism, secondary spur gear and three ring deceleration devices have the advantage that transmission intensity is big, fault rate is low, volume is little, are particularly suitable for using under little in bog-head coal coal-winning machine space, as the to walk inclement condition situation; The RHVC of tractive unit is placed on the active station in the crossheading, has not only reduced the appearance and size of machine, also made things convenient for maintenance and safeguarded.
Description of drawings
Fig. 1 is a traction running part structural representation of the present utility model.
Mark is as follows among the figure: traction electric machine 1, spur gear 2, three-ring speed reducer 3, driving wheel 4
The specific embodiment
The utility model be for generally adopt, high-grade conventional mining and fully-mechanized mining working development a kind of novel by many motor-driven, lateral arrangement, the outer live haulage shearer of girdle machine that power is bigger.Complete machine is mainly by tractive unit; Left and right cutting units; Cylinder; The cooling spray system; Drag compositions such as cable unit.The traction driving section and walking mechanism, hydraulic pressure heightens portion and electrical control division all is placed in the tractive unit, left and right cutting units is whole rocker structure.
This machine is a kind of slide formula of riding girdle electrical haulage shearer of mining along long-armed stope total length shuttle type.Complete machine is bearing on the intermediate channel of transporter by four guide slip shoes of rib side and old man's side respectively, brute force engagement by Cycloidal Wheel in the walking axle group that traction electric machine drove and pin row, under the situation about leading with the guide slip shoe that is contained on the tractive unit, to realize the traction walking of coal-winning machine along the transporter direction, simultaneously two cylinders of left and right sides rocking arm also are rotated under the driving of cutting motor, thereby finish the coal breakage of coal-face and coaling.
Show among the figure, improvement content of the present utility model is original traction electric machine-one-level spur gear-two-stage planetary mechanism-driving wheel mode of traction to be transformed to traction electric machine power input, process secondary spur gear transmission (jackshaft group and output shaft group) and three-ring speed reducer are slowed down, give driving wheel with transmission of power, drive Cycloidal Wheel by driving wheel again and rotate, on transporter, walk thereby Cycloidal Wheel and transporter pin rail gear motion drive coal-winning machine.
The transmission of this secondary spur gear cooperates with three-ring speed reducer on the outer live haulage shearer of the girdle machine that is pulled in did not in the past use, and was a kind of new design.Adopt the low seam mining machinery electric traction device of this traction drive mechanism, secondary spur gear and three ring deceleration devices have the advantage that transmission intensity is big, fault rate is low, volume is little, the two-stage planetary gear speed reducing mechanism transmission intensity that has overcome original draw-gear is little, fault rate is high, bulky shortcoming, is particularly suitable for using under little in bog-head coal coal-winning machine space, as the to walk inclement condition situation.In addition, in the utility model, also the RHVC of tractive unit is placed on the active station in the crossheading, has not only reduced the appearance and size of machine, also made things convenient for maintenance and safeguarded.
