Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: an oil discharge mechanism for a hydraulic coupler free of rotation limitation comprises a guide sleeve 2 arranged on a coupler box body 1, a spoon pipe 3 is connected in the guide sleeve 2 in a sliding mode, a spoon pipe head 4 is arranged at one end, located in the box body 1, of the spoon pipe 3, the section of an opening of the spoon pipe head 4 is a symmetrical figure, one end, located outside the box body 1, of the spoon pipe 3 is rotatably connected in a connecting seat 5, the back side of the connecting seat 5 is hinged with the end portion of a connecting rod 6, the other end of the connecting rod 6 is hinged with the end portion of a swing rod 7, the swing rod 7 is arranged on an electric actuator 8,

The utility model discloses not receive the working process of the oil extraction mechanism for fluid coupling of soon to restriction as follows: under a normal working state, an operator can send an instruction to the oil discharge mechanism through the control system to control the electric actuator 8 to work, when the electric actuator 8 drives the swing rod 7 to swing clockwise, the swing rod 7 can pull the connecting rod 6 and the spoon tube 3 to move towards the outside of the box body 1, and the relative position of the spoon tube head 4 at the end part of the spoon tube 3 in the box body 1 is changed; on the contrary, when the electric actuator 8 drives the swing rod 7 to swing anticlockwise, the swing rod 7 can push the connecting rod 6 and the spoon tube 3 to move towards the inside of the box body 1, the relative position of the spoon tube head 4 in the box body 1 is changed, and the flow of the medium in the box body 1 can be adjusted through the mode;

if the rotating direction of a motor for driving a hydraulic coupler to work needs to be changed, firstly, the box body 1 is disassembled, a worker holds the connecting ring 13 to draw the positioning pin shaft 11 outwards along the radial direction of the spoon pipe 3, after the positioning pin shaft 11 is drawn out from the positioning pin hole on the spoon pipe 3, the spoon pipe 3 can rotate in the circumferential direction, the worker pulls the spoon pipe 3 to rotate 180 degrees (namely the opening direction of the spoon pipe head 4 rotates 180 degrees), then the connecting ring 13 is loosened, the positioning pin shaft 11 moves towards the direction of the spoon pipe 3 under the action of the spring 15 and is inserted into the positioning pin hole on the side, the spoon pipe 3 is connected with the connecting seat 5 again, and the limiting is realized in the circumferential direction and cannot rotate; therefore, the opening direction of the spoon pipe head 4 on the spoon pipe 3 is adjusted, the box body 1 is installed again, and the hydraulic coupler can normally work in the other screwing direction.
