DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Example 1: Please refer to Figure 1-6 In the present embodiment, a novel electro-hydraulic linkage quick-closing actuator comprises an electro-hydraulic linkage quick-closing actuator 1 and a bracket 4. The front and rear sides of the bottom of the electro-hydraulic linkage quick-closing actuator 1 are respectively fixedly connected to the inner wall of the bracket 4. The model of the electro-hydraulic linkage quick-closing actuator 1 is selected according to the use requirements. The bottom of the bracket 4 is connected to a supporting structure 2. The front and rear sides of the supporting structure 2 are respectively connected to a straight plate 5. The top of the electro-hydraulic linkage quick-closing actuator 1 is plugged with a plug block 6, and the plug block 6 is made of rubber. The top of the plug block 6 is fixedly connected to a top cover 7. The left and right sides of the top cover 7 are respectively fixedly connected to a bent plate 8. The outer side of the bent plate 8 is connected to a fixed structure 3.

[0022] The support structure 2 includes a sleeve plate 201 and a vertical plate 202. The top of the sleeve plate 201 is fixedly connected to the bottom of the bracket 4. The inner wall of the sleeve plate 201 fits with the outer wall of the vertical plate 202. The vertical plate 202 is forced to move up and down on the inner wall of the sleeve plate 201. The front and rear sides of the vertical plate 202 are respectively fixed with screws 203. The outer wall of the screw 203 is threadedly connected with a ring 204. The inner side of the ring 204 is tightly pressed against the outer wall of the sleeve plate 201 to fix the position of the screw 203 and the vertical plate 202. The bottom of the vertical plate 202 is fixedly connected with a first bottom plate 205. The outer wall of the screw 203 is slidably engaged with the outer wall groove of the sleeve plate 201. The screw 203 is forced to slide up and down in the outer wall groove of the sleeve plate 201. The front and rear sides of the first bottom plate 205 are respectively fixed with straight plates 5.

[0023] The circular ring 204 in the supporting structure 2 rotates outward on the outer wall of the screw rod 203, so that the inner side of the circular ring 204 is separated from the sleeve plate 201, and then the vertical plate 202 moves downward on the inner wall of the sleeve plate 201, and the moving vertical plate 202 moves downward with the first bottom plate 205, so that the bottom of the first bottom plate 205 is pressed against the top of the pipe, and then the circular ring 204 rotates inward on the outer wall of the screw rod 203, so that the inner side of the circular ring 204 is pressed against the outer wall of the sleeve plate 201, thereby realizing the support of the oil cylinders on the front and rear sides of the electro-hydraulic linkage quick-closing actuator 1, ensuring the service life of the electro-hydraulic linkage quick-closing actuator and saving maintenance costs.

[0024] The fixed structure 3 includes a cross bar 301 and a ball 302. The outer wall of the cross bar 301 is slidably engaged with the outer side of the bent plate 8. The cross bar 301 slides left and right through the outer circular opening of the bent plate 8 under force. The outer side of the cross bar 301 is fixedly connected to the inner side of the ball 302. The ball 302 is convenient for driving the cross bar 301 to move. A ring 303 is fixedly connected to the inner side of the outer wall of the cross bar 301. A spring 304 is sleeved on the outer wall of the cross bar 301. The two ends of the spring 304 are respectively fixedly connected to the outer side of the ring 303 and the inner wall of the bent plate 8. After the ring 303 is forced to move outward, it rebounds due to the elastic force of the spring 304.

[0025] Working principle:

[0026] Working of electro-hydraulic linkage quick closing actuator:

[0027] Adjust the black three-position rotary switch on the controller to the "local" position, and then rotate the red switch to the "open" position. At this time, the motor starts to run, driving the oil pump to generate a high-pressure oil source, which enters the rodless chamber of the oil cylinder, and the solenoid valve is also activated, thereby driving the gear transmission mechanism to rotate counterclockwise. The actuator will start to open the valve at the preset speed until it is fully open, and automatically stop the valve opening action. Conversely, the valve can be closed by operating the same way.

[0028] Installation support of electro-hydraulic linkage quick closing actuator:

[0029] The bottom of the electro-hydraulic linkage quick-closing actuator 1 is connected to the external pipeline, and then the ring 204 rotates outward on the outer wall of the screw rod 203, so that the inner side of the ring 204 is separated from the sleeve plate 201, and then the vertical plate 202 moves downward on the inner wall of the sleeve plate 201, and the moving vertical plate 202 moves downward with the first bottom plate 205, so that the bottom of the first bottom plate 205 is tightly pressed against the top of the pipeline, and then the ring 204 rotates inward on the outer wall of the screw rod 203, so that the inner side of the ring 204 is tightly pressed against the outer wall of the sleeve plate 201, thereby realizing the support of the oil cylinders on the front and rear sides of the electro-hydraulic linkage quick-closing actuator 1.

[0030] Maintenance of electro-hydraulic linkage fast closing actuator:

[0031] Hold the ball 302 and pull it outward, the ball 302 will move the cross bar 301 outward through the bent plate 8, so that the inner side of the outer wall of the cross bar 301 is separated from the outer wall circular opening of the electro-hydraulic linkage quick-closing actuator 1. At the same time, the cross bar 301 cooperates with the ring 303 to squeeze the spring 304, and then lifts the bent plate 8 upward, the bent plate 8 moves the top cover 7 upward, so that the plug 6 is separated from the top of the electro-hydraulic linkage quick-closing actuator 1, and then the interior of the electro-hydraulic linkage quick-closing actuator 1 is maintained. After the maintenance is completed, the plug 6 is inserted back into the top of the electro-hydraulic linkage quick-closing actuator 1, so that the outer side of the bottom of the top cover 7 is fitted with the top of the electro-hydraulic linkage quick-closing actuator 1, and the ball 302 is released. The spring 304 provides a rebound force to make the ring 303 move the cross bar 301 inward, so that the cross bar 301 is plugged into the circular opening of the outer wall of the electro-hydraulic linkage quick-closing actuator 1.

[0032] Example 2: Please refer to Figure 1-6 In this embodiment, a novel electro-hydraulic linkage quick-closing actuator further includes a second base plate 9, the front side of the second base plate 9 is plugged into the outer wall of the rear straight plate 5.

[0033] Working principle:

[0034] When the pipe that the bottom of the first bottom plate 205 contacts is thinner, the outer wall grooves of the two second bottom plates 9 can be plugged into the outer walls of the straight plates 5 on the front and rear sides, so that the first bottom plate 205 cooperates with the second bottom plate 9 to increase the bottom contact surface, thereby increasing the contact surface of the thin pipe and preventing the thin pipe from being damaged by compression.
