Description

Eccentric torque balance output shifting fork box

Technical Field

The utility model relates to a shift fork case technical field especially relates to an eccentric formula moment balance output shift fork case.

Background

The shifting fork box is also called a shifting fork mechanism, the shifting fork box is used for converting the linear motion of the hydraulic cylinder into the rotary angular stroke motion, and the output force under the same pressure is also a fixed value due to the fact that the area of a piston in the hydraulic cylinder is a fixed value; therefore, another effect of the shifting fork mechanism is that the constant output force is converted into the changed torque (torque) through the changed torque, so that the output torque of the shifting fork mechanism more accords with the characteristic of valve torque, and in the selection of the shifting fork box, an eccentric torque shifting fork box is mostly adopted, and the eccentric torque shifting fork box utilizes an eccentric operation mode, so that the generated torque is larger, and compared with the shifting fork box of an early symmetrical mode, the diameter volume required by the hydraulic cylinder can be reduced while the opening and closing are realized.

As an actuating mechanism, the existing eccentric torque fork box generally comprises a fork box body, a guide block mechanism, a guide shaft, a fork and other parts and corresponding connecting pieces, wherein the guide block mechanism, the guide shaft, the fork and other parts are arranged in the fork box body; for example, the chinese patent, granted publication No. CN207554459U, is an eccentric shifting fork mechanism, comprising a valve driving shaft and a shifting fork body fixedly connected to each other, wherein the shifting fork body is provided with a bar-shaped guide groove, an eccentric angle (β) formed by a center line of the guide groove relative to a center line of the valve driving shaft is an acute angle, and further, the eccentric angle (β) is 5 ° to 15 °; the eccentric shifting fork mechanism is arranged in a shifting fork box, a guide block mechanism and a guide shaft are further arranged in the shifting fork box, wherein the valve driving shaft is connected with a valve switch and drives the valve switch to move, a movable connecting structure is formed between the shifting fork body and the guide block mechanism through a guide groove, a movable connection capable of linearly sliding relatively is formed between the guide block mechanism and the guide shaft, the shifting fork box is connected with a hydraulic cylinder, a piston of the hydraulic cylinder is connected with the guide block mechanism, the guide block mechanism is driven to linearly slide along the guide shaft through the piston, meanwhile, the shifting fork body is driven to rotate within a certain angle range by the guide block mechanism, and finally, the valve driving shaft is driven to synchronously rotate through the rotation of the shifting fork body, so that the torque is output to control the opening and closing of the valve; the eccentric shifting fork mechanism is formed by arranging a strip-shaped guide groove on a shifting fork body, wherein the eccentric angle formed by the center line of the guide groove relative to the center line of a valve driving shaft is an acute angle; therefore, when the eccentric shifting fork mechanism moves, the output torque of the shifting fork mechanism can be improved even under the premise of not increasing the size of the hydraulic cylinder and the piston of the hydraulic cylinder, the torque is output in a balanced manner, and the overall production cost is reduced.

The above patent realizes that the output torque of the shifting fork mechanism is improved on the premise of not increasing the size of the hydraulic cylinder and the piston thereof, so that the torque of the shifting fork mechanism is balanced and output, but the shifting fork mechanism still has some defects; its shift fork case exists the shortcoming of being not convenient for open fast and overhaul, and for the steady operation of shift fork incasement portion, the staff need regularly overhaul the maintenance in the shift fork incasement, consequently need regularly open the maintenance, improves to this phenomenon, therefore we have proposed eccentric formula moment balance output shift fork case for solve above-mentioned problem.
