Abstract

The invention discloses a telescopic hydraulic cylinder capable of bearing rotational torque, which belongs to the field of telescopic belt conveyors. It includes a cylinder body fixed on the support, and a piston rod matched with the cylinder body; a connection mechanism is fixed at the end of the piston rod; a pulley block is installed on the connection mechanism; the front and rear sides of the connection mechanism are respectively fixed with A sliding rod; the sliding rod is arranged in parallel with the piston rod; a support plate is respectively fixed on the front and rear sides of the cylinder body; a through hole is opened on the support plate, and the sliding rod is slidably installed on the corresponding support in the board through hole. The two sliding rods of the present invention are used in combination with the piston rod of the hydraulic cylinder. When the object of the present invention has a rotational torque, the piston rod of the hydraulic cylinder will not rotate together with the object. In addition, due to the support effect of the two sliding rods, the piston rod of the hydraulic cylinder can bear a large radial force, preventing the piston rod of the hydraulic cylinder from bending and deforming, and realizing the function of transmitting a large force with a small hydraulic cylinder.

Description

technical field [0001] The invention relates to the field of telescopic belt conveyors, in particular to a telescopic hydraulic cylinder capable of bearing rotational torque. Background technique [0002] Such as figure 1 As shown, the tensioning hydraulic cylinder is an important part of the telescopic belt conveyor to realize the telescopic function. For a long time, the tensioning hydraulic cylinder is an ordinary high-pressure hydraulic cylinder, which can withstand greater tension and support. And the seal is better, but it can't bear the rotating torque. When the belt is tightened, under the action of the rotating torque of the wire rope itself, the hydraulic cylinder is easy to rotate, and the wire rope is entangled together, so that the winch cannot normally retract the wire rope and tension the belt. Replacing the steel wire rope with a torque-free wire rope can avoid the above problems, but because the torque-free wire rope is expensive, it is rarely used in coal...
