Description
(1), technical field
The utility model relates to a kind of machinery of underground coal mining, particularly exploits the drum shearer of girdle.
(2), background technology
The reserves of China's girdle account for more than 20% of whole coal reservess, but coefficient of mining is not as good as 5%.Because girdle geological conditions complexity, abominable, alternative type is few, and mostly is the early 1990s level, has to adopt big gun to be adopted, and therefore has the serious wasting of resources and environment pollution.
(3), summary of the invention
The purpose of this utility model is to design a kind of drum shearer that can exploit girdle.
The utility model is achieved in that it comprises tractive unit, a left side, right cutting units, hydraulic pressure and electrical appliance part, tractive unit is that cross section is the rectangular box body of rectangle, fix manual platform on its vertical front, fixed traction mechanism in it, it comprises traction electric machine, main pump, auxiliary pump, motor, the hydraulic drive case, electric control box and walking case, traction electric machine is connected with auxiliary pump with main pump by gear pair, the main pump drawing motor, the output shaft of motor and the input of speed reducing gear pair are fixed, the output of speed reducing gear pair is road wheel fixedly, on the manual platform electrical appliance button and hydraulic control lever are arranged, auxiliary pump is by an oil circuit and a driving left side, adjust high cylinder and brake that right cutting units swings up and down link; Left side cutting units is hinged with the left end of tractive unit respectively, left side adjust high cylinder and left cutting units and tractive unit are hinged, a fixing left side is cut every motor, gear pin row and the tube that rolls left on the cutting units of a left side, a left side is cut every motor and is directly driven the tube that rolls left by the gear pin row, right cutting units is identical with left cutting units structure, bilateral symmetry, but the switched in opposite of left and right cylinder.
Described haulage gear is two, is located at the two ends, the left and right sides of tractive unit respectively.
For the size up and down that makes tractive unit is littler, traction electric machine and left and right cutting motor be lateral arrangement all.
Described left and right section outside that is arranged in old man's side every motor and motor.
In order to prevent that the working seam inclination angle from gliding than ambassador, fixing brake on the motor drive shaft in the tractive unit, brake is controlled automatically by auxiliary pump hydraulic pressure.
Because the rotation of the walking of tractive unit, left and right cylinder is all dragged by separately motor respectively, the diameter of each motor is less, and drive chain is short, so the size up and down of tractive unit and left and right cutting units is less, compact conformation can be exploited girdle.Installed power is big, the production efficiency height.Tractive unit is an integral body, and good rigidly can satisfy the condition of work of girdle.Two driving pin row formula chainless haulages are from band brake.The double-tractor structure has reduced the specific pressure of the travelling gear pin row flank of tooth, has improved the application life of eating bar, and when down-hole coal excavation, in case there is a haulage gear to break down, still can adopts adequate measure to realize single traction, and can not cause stopping production.Because left and right section is arranged in the outside of old man's side every motor and motor, so easily the down-hole is changed.

(5), the specific embodiment
The utility model comprises tractive unit 5, left and right cutting units 2,7, hydraulic pressure and electrical appliance part, as shown in Figure 1, 2.Tractive unit 5 is the rectangular box body of rectangle for cross section, fixes manual platform on its vertical front, and electrical appliance button and hydraulic control lever are arranged on the manual platform.The identical left and right haulage gears 4,6 of fixed structure in the tractive unit 5 are located at the two ends, the left and right sides of tractive unit respectively, all comprise traction electric machine 9, main pump 13, auxiliary pump 16, motor 19, hydraulic drive case, electric control box and walking case.Traction electric machine 9 drives main pump 13 by gear 10,11,12, drives auxiliary pump 16 by gear 14,15 again, as shown in Figure 3.Described main pump 13 drawing motors 19, fixed gear 221 on the output shaft of motor 19, and gear 21 is driven gear 20, gear 22, internal tooth casing 23, central gear 24, planetary gear 25, driving wheel 26 and road wheel 27 successively.Auxiliary pump 16 links by oil circuit and left and right sides adjust high cylinder 28,29 and the brake 40 that the left and right cutting units 2,7 of driving swings up and down, as shown in Figure 4.Left side cutting units 2 is hinged with the left end of tractive unit 5, and left adjust high cylinder 28 is hinged with left cutting units 2 and tractive unit 5 respectively, and left adjust high cylinder 28 can drive left cutting units 2 relative tractive units 5 and swing up and down.A fixing left side is cut every motor 3 on the cutting units 2 of a left side, and fixed gear 32 on the output shaft of motor 3 is cut on a left side, and gear 32 drives idle pulley 31, gear 33, clutch gear 34, gear 35,36, planetary gear 37 respectively and the tube 1 that rolls left successively, as shown in Figure 3.Right cutting units 7 is identical with left cutting units 2 structures, bilateral symmetry, but the switched in opposite of left and right cylinder 1,8.For the size up and down that makes tractive unit 5 is littler, described left and right sides traction electric machine 4,6 and left and right cutting motor 3,38 be lateral arrangement all.The down-hole is changed for convenience, described left and right section outside that is arranged in old man's side every motor 3,38 and motor 19.
Glide when preventing to exploit bigger coal seam, inclination angle, with gear 21 meshing gears 39 on 19 in the motor in the tractive unit 5, with gear 39 coaxial fixedly brakes 40, as shown in Figure 3.After coal-winning machine starts, the right-side cavity that the pressure control oil that auxiliary pump 16 is discharged enters brake plunger through electromagnetic valve, promote piston overcome disk spring elastic force and toward moving left, drive the platen that is fixed together with it simultaneously, make between the inside and outside friction plate and produce the gap, going up brake 40 joining sliding key sleeves with 19 in motor in the tractive unit 5 can rotate freely, and this moment, brake 40 was in the state of declutching.If motor stall, braking electromagnetic valve resets, make right chamber of brake 40 pistons and oil sump conducting, piston moves right under the effect of disk spring, press inside and outside friction plate by platen, produce braking moment, gear drive is stopped by frictional force, coal-winning machine has just been lived by lock like this, can not glide.If need artificial brake off, plug screw can be removed, fast with bolt and suitable pad, piston is sling, inside and outside friction plate is unclamped get final product.
