The tensioning device is not beneficial to the standard management of a coal mine to working face equipment, is easy to cause safety accidents, and is not beneficial to the tensioning of a traction chain.
In order to achieve the above object, the utility model provides a following technical scheme: a chain double-traction device of coal mining equipment comprises a traction part and traveling boxes, wherein the traction part is provided with the traveling boxes which are symmetrically distributed front and back, and the traction part is provided with a traction motor, a transmission box, a planetary mechanism, a transmission shaft and a chain wheel; the walking box is provided with a driven sprocket and a protective shell.
Preferably, the walking boxes are symmetrically distributed at the two sides of the traction part in the front-back direction; traction portion and walking case adopt split type structure, and the walking case passes through high strength bolted connection with traction portion.
Preferably, the traction part evenly distributes the torque of the traction motor to the chain wheels on the front side and the rear side of the traction part through the transmission mechanism.
Preferably, the traveling box is a circular chain and chain wheel meshing protection device, the driven wheel is fixed on the traveling box, and the driven chain wheel is installed on the traveling box to ensure the meshing wrap angle of the circular chain and the chain wheel.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) through the designed double walking boxes, the stress condition of the coal mining equipment is further optimized, the stress condition of a single chain wheel is reduced, and the service life of the chain wheel is prolonged; the deflection bending moment of the coal mining equipment is reduced, and the walking track of the coal mining equipment is optimized;
(2) through the design of the double-traction chain, the traction chain is the walking and guiding track of the coal mining equipment, and through the design of the double-track, the swing range of the coal mining equipment is limited, and the walking track of the coal mining equipment is further optimized.
