[0024] See also Figure 1-5 A hydraulic single-cantilever mechanical arm includes a horizontal arm 1 fixedly connected to a wall, and also includes a transmission mechanism, the transmission mechanism includes a sliding seat 2 slidably connected to the horizontal arm 1, and a lifting assembly is provided on the sliding seat 2; the lifting assembly includes a traction rope 21, and the two ends of the traction rope 21 are respectively fixedly connected to the lower end of the sliding seat 2 and the vertical plate 31, and the traction rope 21 passes around the first pulley 22 and the second pulley 23 in turn, the first pulley 22 is rotatably set on the clamping claw 24 for clamping the product, and the second pulley 23 is rotatably set on the lower side of the sliding seat 2, the vertical plate 31 is fixedly connected to the output end of the hydraulic cylinder 3, and the hydraulic cylinder 3 is fixedly installed on the horizontal arm 1, and a telescopic assembly is also provided between the vertical plate 31 and the sliding seat 2.

[0025] Through the transmission mechanism, when the product is lifted, the hydraulic cylinder 3 drives the vertical plate 31 to move, the vertical plate 31 moves to drive the traction rope 21 to move, the traction rope 21 drives the clamping claw 24 to move upward through the first pulley 22, in this process, the vertical plate 31 drives the telescopic assembly to move, and the telescopic assembly does not drive the sliding seat 2 to move, so as to avoid directly driving the product to move horizontally and collide with surrounding products; when the product is lifted to a specified height, the vertical plate 31 moves to drive the sliding seat 2 to move through the telescopic assembly, and the sliding seat 2 moves to drive the first pulley 22 and the clamping claw 24 to move synchronously through the traction rope 21, thereby realizing the switching of the product from a low station to an adjacent high station; when the hydraulic cylinder 3 drives the sliding seat 2 to return to the initial position through the vertical plate 31, the telescopic assembly is also reset. The utility model optimizes and simplifies the equipment through mechanical structure design, completes the movement of the product from a low station to a high station, reduces the complexity of the equipment and the maintenance frequency, and improves production efficiency.

[0026] The combined force borne by the second pulley 23 during operation causes the sliding seat 2 to tend to slide along the cross arm 1, so the contact surface between the sliding seat 2 and the cross arm 1 is selected to have a rougher surface, or an anti-slip pad is added to increase the friction between the sliding seat 2 and the cross arm 1, so that the traction rope 21 will not drive the sliding seat 2 to move through the second pulley 23.

[0027] Furthermore, the cross arm 1 is provided with a slot 11 for exposing the second pulley 23, and one end of the cross arm 1 is fixedly connected to a fixing plate 12, and the fixing plate 12 is fixedly connected to the wall.

[0031] Working principle:

[0032] When lifting the product, the hydraulic cylinder 3 drives the vertical plate 31 to move, and the movement of the vertical plate 31 drives the traction rope 21 to move, and the traction rope 21 drives the clamping claw 24 to move upward through the first pulley 22. In this process, the vertical plate 31 drives the outer rod 41 to move along the inner rod 4, that is, at this time, the inner rod 4 does not drive the sliding seat 2 to move, so as to avoid directly driving the product to move horizontally and collide with surrounding products; when the product is lifted to a specified height, the vertical plate 31 drives the outer rod 41 to move so that the locking rod 43 on the inner rod 4 extends into the locking groove 45 under the action of the spring 44, that is, the outer rod 41 is moved. The movement of the rod 41 drives the sliding seat 2 to move through the inner rod 4, and the movement of the sliding seat 2 drives the first pulley 22 and the clamping claw 24 to move synchronously through the traction rope 21, thereby realizing the switching of the product from the low position to the adjacent high position; when the hydraulic cylinder 3 drives the sliding seat 2 to return to the initial position through the vertical plate 31, the unlocking rod 46 contacts the cross arm 1, and the sliding seat 2 continues to move, so that the inclined surface of the unlocking rod 46 contacts the unlocking groove 47, so that the locking rod 43 moves away from the locking groove 45, so that the outer rod 41 can move to the initial position along the inner rod 4. The utility model optimizes and simplifies the equipment through mechanical structure design, completes the movement of the product from the low position to the high position, reduces the complexity of the equipment and the maintenance frequency, and improves the production efficiency.
