The first oil cylinder 50 is installed at the right end of the clamping cross beam 23, and a piston rod of the first oil cylinder is movably connected with the first hinge block 203. The second cylinder 60 is mounted at the left end of the clamping beam, the piston rod of the second cylinder is connected with the fixed rod member 25, which in this application becomes a movable rod member, which is movably fitted in the guide hole. The first oil pipe 71 and the second oil pipe 72 pass through the clamping beam 23.
In operation, the operator pulls the right handle 209, the right handle rotates clockwise around the hinge 234, and the first hinge block 203 drives the movable rod 211 to displace toward the fixed rod 25 via the second hinge block 204. Synchronously, the first hinge block 203 drives the piston rod of the first cylinder 50 to move the first piston 53 to the left, the oil in the left chamber 51 of the first cylinder enters the left chamber 61 of the second cylinder through the first oil pipe 71, the oil in the left chamber of the second cylinder pushes the piston of the second cylinder 60 to move to the right, and the piston rod of the second cylinder drives the fixed rod 25 connected with the second cylinder to move to the right, so that the fixed rod and the movable rod 211 move towards each other to clamp the gearbox therebetween. The oil in the second cylinder right chamber 62 enters the first cylinder right chamber 52 through the second oil pipe 72 to assist the piston of the first cylinder to move left.
With reference to fig. 2 and 3, the first piston 53 of the first cylinder is provided with a valve cavity, a valve body 531 is movably matched in the valve cavity, the valve cavity is divided into a left cavity 532 and a right cavity 533 by the valve body, the left cavity is provided with a left spring 534 for limiting the left of the valve body, and the right cavity is provided with a right spring 535 for limiting the right of the valve body; the first piston is provided with a first through hole 536, the cylinder body 54 of the first oil cylinder is provided with a second through hole 541, the left side of the first piston is provided with a third through hole 537 communicated with the left cavity, the right side of the first piston is provided with a fourth through hole 538 communicated with the right cavity, the first through hole can be aligned with the second through hole, and the valve body can block the first through hole; the second through hole is connected to a hydraulic pump 80 through a third oil pipe 73, the hydraulic pump is connected to an oil storage tank 81, and the oil storage tank is connected to the second oil cylinder 60.
Initially, the valve body 531 connected to the first cylinder 50 blocks the first through hole 536, which is aligned with the second through hole 541. The right handle 209 rotates clockwise about the hinge 234, the valve 531 moves left, the left spring 534 is compressed, the valve does not block the first through hole any more, and the high-pressure oil from the hydraulic pump 80 enters the right chamber 533 of the valve chamber and enters the right chamber 533 of the first cylinder through the fourth through hole 538 to assist the left movement of the first piston 53. With the left movement of the first piston, the high-pressure oil directly enters the right chamber 533 of the first cylinder through the second through hole 541. The right handle 209 rotates counterclockwise about the hinge 234, the valve body 531 moves right, the right spring 535 is compressed, the valve body no longer blocks the first through hole, and the high-pressure oil from the hydraulic pump 80 enters the left chamber 532 of the valve chamber, enters the left chamber 532 of the first cylinder through the third through hole 537, and assists the right movement of the first piston 53. With the right movement of the first piston, high pressure oil directly enters the left chamber 532 of the first cylinder through the second through hole 541. The power-assisted action of the high-pressure oil of the hydraulic pump enables an operator to operate the right handle 209 with labor saving.
The first piston 53 is provided at the periphery thereof with an annular protrusion 530 which is in contact with the cylinder body 54 of the first cylinder to partition the cylinder body of the first cylinder into left and right chambers, and a first through-hole 536 radially penetrates the annular protrusion. A seal ring is mounted on the annular boss 530. Initially, the valve body 531 connected to the first cylinder 50 blocks the first through hole 536, which is aligned with the second through hole 541. The right handle 209 rotates clockwise about the hinge 234, the valve 531 moves left, the left spring 534 is compressed, the valve does not block the first through hole any more, and the high-pressure oil from the hydraulic pump 80 enters the right chamber 533 of the valve chamber and enters the right chamber 533 of the first cylinder through the fourth through hole 538 to assist the left movement of the first piston 53. With the left movement of the first piston, the narrow annular protrusion 530 can rapidly pass the second through hole 541, so that the high-pressure oil directly enters the right chamber 533 of the first cylinder through the second through hole 541.
Referring to fig. 2 and 3, the left chamber 61 of the second cylinder is connected to the oil storage tank 81 through a fourth oil pipe 74, the right chamber 62 of the second cylinder is connected to the oil storage tank through a fifth oil pipe 75, and the fourth oil pipe and the fifth oil pipe are both provided with check valves. High pressure oil from the hydraulic pump 80 enters the right chamber 533 of the first cylinder to assist the left movement of the first piston 53. The oil in the first cylinder left chamber 51 enters the second cylinder left chamber 61 through the first oil pipe 71, the piston and the piston rod of the second cylinder move to the right, and the oil in the second cylinder right chamber 62 enters the first cylinder right chamber 52 through the second oil pipe 72. When the piston of the second cylinder is displaced to the right limit position, the oil from the left chamber of the first cylinder still enters the left chamber of the second cylinder, the pressure in the left chamber of the second cylinder increases, the check valve is opened, and the oil flows into the oil storage tank 81 through the fourth oil pipe 74. When the piston of the second cylinder is displaced to the left limit position, the oil still from the right chamber of the first cylinder enters the right chamber of the second cylinder, the pressure in the right chamber of the second cylinder increases, the check valve is opened, and the oil flows into the oil storage tank 81 through the fifth oil pipe 75.
