Abstract
A hydraulic tensioning mechanism consists of a rack, a hydraulic cylinder, a self-lubricating guide plate, a sprocket shaft seat and a sprocket, wherein the hydraulic cylinder is fixed on the rack, and the sprocket shaft seat and the sprocket are connected. When the sprocket is required to be tensioned, a hydraulic rod extends to push the sprocket shaft seat, the sprocket shaft seat is clamped on the self-lubricating guide plate to drive the sprocket to run, a track link chain coated on the sprocket is tensioned, the pressure of the hydraulic cylinder is adjusted, and the tensioning force is controlled. The hydraulic cylinder is tensioned, the tensioning pressure can be adjusted in a hydraulic system and the tensioning pressure is not changed to be small when the mechanism is used for a long time.
Description
Technical field
The utility model relates to building mechanical equipment, relates in particular to the polyurethane plate automatic production lines, the caterpillar block tension mechanism of tracked machine.
Background technology
Former tracked machine tensioner system is tensioned, uses for a long time spring easily tired, and the tensioner dynamics diminishes, and adjusts cumbersome.
Summary of the invention
The purpose of this utility model provides hydraulic expansion mechanism in order to address the above problem.
The purpose of this utility model is achieved in that hydraulic expansion mechanism, it is comprised of frame, hydraulic actuating cylinder, self-lubricating guide plate, sprocket wheel axle bed and sprocket wheel, and hydraulic actuating cylinder is fixed on frame, and the sprocket wheel axle bed is connected with sprocket wheel, when needs tensioner sprocket wheel, hydraulic stem stretches out, and promotes the sprocket wheel axle bed, and the sprocket wheel axle bed is stuck on the self-lubricating guide plate, the motion of band movable sprocket, make the caterpillar block chain tensioner that covers on sprocket wheel, regulate cylinder pressure, just can control expanding force.
This applicable novel beneficial effect is: use the hydraulic actuating cylinder tensioner, tensioner pressure can be in regulation of hydraulic system, and long-time use the problem that tensioner pressure diminishes can not occur.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, hydraulic expansion mechanism, it is comprised of frame 1, hydraulic actuating cylinder 2, self-lubricating guide plate 3, sprocket wheel axle bed 4 and sprocket wheel 5, hydraulic actuating cylinder 2 is fixed on frame 1, sprocket wheel axle bed 4 is connected connection with sprocket wheel, when needs tensioner sprocket wheel, hydraulic stem stretches out, promote sprocket wheel axle bed 4, sprocket wheel axle bed 4 is stuck on self-lubricating guide plate 3, and 5 motions of band movable sprocket make the caterpillar block chain tensioner that covers on sprocket wheel 5, regulator solution cylinder pressure 2 pressure just can be controlled expanding force.
