Abstract
An electric traction coal cutter for thin coal layer, including a cutting part and a traction part, the two parts are connected with each other by means of butt joint; which is characterized in that: the cutting part includes a spiral roller and a gear group drive system, and an electromotor connected directly with the gear group drive system is arranged at the cutting part; the traction part is composed of a traction electromotor, a gear group and a drive sprocket. Aiming at the issues brought about by the ZB [2]-100 coal cutters with a hydraulic traction that the traction is deficient with a slow traction speed and the serious oil spill caused by the transmission relationship between each component; moreover, the parts is easy to be damaged and the maintenance rate is high, The utility model replaces the hydraulic traction with an electrical traction; at the same time, the entire structure layout of coal cutter can be changed synchronously and the drive system between each part is reduced so as to form two parts namely a cutting part and a traction part which can run independently. The utility model has the advantages in that the traction power is big with a high traction speed; moreover, the complete machine can run reliably.
Description
Technical field
The utility model belongs to coal-cutting machinery, particularly a kind of electric traction low seam mining machinery.
Background technology

The utility model has changed the complete machine layout structure, is divided into the two large divisions: cut part and electric traction part, cut partly adopt existing ZB
2The cutting units of X-100 type coal-winning machine and motor (100 kilowatts) are formed, and it mainly acts on is to drive cylinder, the work of finishing coal breakage and coalingging.Motor directly docks with original cutting units, 100 kilowatts of power directly use for cut, guaranteed that cutting units has enough dynamically workings, simultaneously motor directly is connected with cutting units and has reduced middle transmission link, make more compact structure between the two, effectively avoid loosening phenomenon, guarantee even running.Electric traction has partly changed hydraulic haulage, introduces the electric traction technology, and traction power is big, the hauling speed height, and it mainly acts on is the walking that realizes coal-winning machine.Adopt traction motor (11 kilowatts) as power source, directly drive the mechanical driving part (gear train) in the traction element casing, after slowing down, drive the output of two drive sprockets.The electric traction part can be by being provided with electric control box (ac variable frequency speed regulation mechanism) control motor speed, and the speed of travel when realizing coal-winning machine work is regulated.Layout of the present utility model changes, and has reduced the transmission system between each major part, forms the cut part and the traction element of energy independent operating, no longer has transmission system between two parts.
Described cut part is as prior art, and helix drum also connects hoist cylinder, and hoist cylinder is connected with plunger displacement pump, and plunger displacement pump is connected with the gear train transmission system.Hoist cylinder can the adjustable screw cylinder height.
Cut part all the other structures except the motor of setting up are with existing ZB
2The frame mode that X-100 type coal-winning machine is taked, particularly gear train transmission system, purpose are to realize slowing down and drive helix drum turning round, and can adopt any technical pattern mode that can realize.
The gear train of electric traction part is realized slowing down and is driven the drive sprocket running, thereby realizes the walking of coal-winning machine.The frame mode of gear train can be any technical pattern mode that can realize.The utility model provides a kind of and has been meshing with each other or with the frame mode of through-drive by a plurality of gears, comprise gear Z1～Z12, gear Z1 is connected with traction motor is coaxial, gear Z1 is by idle wheel Z2 and gear Z3 engagement, gear Z3 is connected with gear Z4 is coaxial, gear Z4 and gear Z5 engagement, gear Z5 is connected with gear Z6 is coaxial, gear Z6 and gear Z7 engagement, gear Z7 is connected with gear Z8 is coaxial, gear Z8 and gear Z9 engagement, gear Z9 and gear Z10 form duplicate gear, gear Z10 meshes with gear Z11 and gear Z12 respectively, and gear Z11 is connected with drive sprocket Z15 is coaxial, and gear Z12 is connected with drive sprocket Z13 is coaxial.
During use, between drive sprocket Z13 and drive sprocket Z15, can be added with by movable sprocket Z14.
Advantage of the present utility model:
The tractive force deficiency that the utility model causes at hydraulic haulage, hauling speed is low, exist drive connection to cause serious leakage of oil between each big parts, damage parts, problems such as maintenance rate height, by having introduced the electric traction technology, the change hydraulic haulage is electric traction, changes the total layout of coal-winning machine simultaneously, has reduced the transmission system between each major part, form the cut and the traction two large divisions of energy independent operating, no longer have transmission system between two parts.Concrete characteristics are embodied in the following aspects:
(1), adopt single motor mode of traction, simple in structure, reliable, easy to maintenance;
(2), traction power is big, the hauling speed height;
(3), adopt hardened face gear transmission, transmission efficiency height, reliable transmission;
(4), the bearing of power transmission shaft group can adopt roller bearing, supporting capacity is big, long service life.
(5) drive sprocket of electric traction part adopts two drive sprocket structures, makes coal-winning machine can remove the tensioning apparatus of conduction chain.This is through increased the cornerite on drive sprocket by movable sprocket because of the chain between two drive sprockets, when chain gear transmission, chain between two drive sprockets is in the state of being tensioned all the time, as long as the chain of coal-winning machine slack list can mesh with drive sprocket, the chain phenomenon just can not occur jumping.So the tight chain work forward of coal-winning machine fortune only need be fixed the chain of lead one end earlier, utilize the chain tension of coal-winning machine with pilled-in selvedge after, fixing the getting final product in the stretching back of the chain of slack list.
