Disclosure of Invention
The invention aims to solve the problems of the conventional riding wheel device and provide a hydraulic catch wheel device which has the advantages of prolonging the service life and reducing the manufacturing cost.
The specific scheme of the invention is as follows: the utility model provides an improve life reduction manufacturing cost's hydraulic pressure fender wheel device for support drum-type drying-machine's wheel area, the on-line screen storage device comprises a base, a fixed pneumatic cylinder support that is equipped with of base top one end, the pneumatic cylinder is equipped with on the pneumatic cylinder support, the output of pneumatic cylinder is connected with a fender wheel seat, sliding connection between fender wheel seat and the base, one side that fender wheel seat is close to the wheel area is equipped with the opening, keep off the inside vertical fender wheel axle that is equipped with of wheel seat, keep off and be equipped with the fender wheel through the bearing in the wheel axle, keep off partly opening that stretches out fender wheel seat of wheel excircle, the pneumatic cylinder is located same height to the thrust that keeps off wheel seat and the thrust that keeps off the wheel and receive the wheel area and arranges.
Two sides of the wheel belt are respectively provided with a travel switch, and the two travel switches are respectively in signal connection with the hydraulic cylinder so as to control the telescopic action of the hydraulic cylinder.
The two sides of the bottom plate of the catch wheel seat are respectively provided with a guide rail which protrudes outwards, the two sides of the base are respectively provided with a guide rail pressing plate, the guide rail pressing plates are arranged by being attached to the outer sides of the guide rails, and the guide rails are connected with the guide rail pressing plates in a sliding mode.
A sliding rail is arranged between the base and the bottom surface of the catch wheel seat, and the catch wheel seat moves along the sliding rail.
The invention has the following beneficial effects: 1. the thrust of the hydraulic cylinder to the catch wheel seat and the thrust of the catch wheel on the wheel belt are positioned at the same height, so that the force of the catch wheel and the acting force of the hydraulic cylinder are positioned on the same straight line, the traditional force transmission mode through torque is cancelled, and the upper end and the lower end of the catch wheel shaft are arranged in the catch wheel seat and are in a simply supported state, so that the stress conditions of the catch wheel and the catch wheel shaft are greatly improved, and the service life is prolonged; 2. because the stress condition is improved, the model selection of the blocking wheel, the blocking wheel shaft, the bearing and the hydraulic cylinder can select smaller models, thereby saving the cost, and the structure is simpler, so that the installation, the disassembly and the maintenance are more convenient.
