The arrangement of the traveling beam and the traveling trolley enables the hoisting device to move freely in the horizontal direction, the rotating lifting ring realizes the angle adjustment of the hoisting device itself, and the lifting cylinder realizes the flexible adjustment of the hoisting device in the vertical direction.

This method avoids the damage caused by directly contacting the edge of the steel plate with a hook or a rope in the traditional hoisting method.

[0019] (4) Strong adaptability: By adjusting the position and length of the telescopic frame and the clamping mechanism, this device can meet the lifting requirements of steel plates with different sizes, weights, and shapes. This flexibility gives this device broad application prospects in the field of hydraulic support processing.

[0020] (5) Reducing labor intensity: This device realizes automated and semi-automated lifting operations, greatly reducing the labor intensity of workers.

[0057] The working principle of the present utility model is as follows:

[0058] Step 1: When it is necessary to hoist the steel plate 32, first drive the entire fixing frame 6 to move by holding the control handle 34. The horizontal rotation of the rotary ring 4 can control the horizontal rotation of the entire fixing frame 6 around the rotation axis of the rotary ring 4. The sliding of the traveling trolley 3 inside the traveling beam 2 can drive the entire fixing frame 6 to move horizontally. The rotation between the traveling beam 2 and the column 1 can drive the fixing frame 6 to rotate horizontally around the axis of the column 1 over a large range, so that the fixing frame 6 and the telescopic frame 7 are moved above the steel plate 32 to be hoisted, and the angles of the fixing frame 6 and the telescopic frame 7 are adapted to the angle of the steel plate 32 to be hoisted.

[0059] Step 2: According to the length of the steel plate 32, control the first telescopic cylinder 20 to extend. The first telescopic cylinder 20 drives the front telescopic frame 7 to move forward. The front telescopic frame 7 drives the left rack 21 to move forward. Since both the left rack 21 and the right rack 22 are engaged with the transmission rack, the right rack 22 starts to move backward, and the rear rack drives the rear telescopic frame 7 to move backward. Therefore, the front and rear telescopic frames 7 extend forward or backward on the fixing frame 6 respectively, so that the distance between the clamping mechanisms 9 on the front and rear sides is adapted to the length of the steel plate 32.

[0060] Step 3: Control the piston rod of the lifting cylinder 5 to extend, so that the entire fixing frame 6 and the telescopic frame 7 descend, and the suction cup body 27 contacts the upper end surface of the steel plate 32. During the contact between the suction cup body 27 and the steel plate 32, the insertion rod 25 slides inside the fixing plate 24, and the buffer spring 26 is compressed, thereby buffering the contact process.

[0061] Step 4: Control the air pump to evacuate the inside of the suction cup body 27 to make the suction cup body 27 fixedly connected to the steel plate 32.

[0062] Step 5: Control the piston rod of the lifting cylinder 5 to contract, driving the steel plate 32 to rise by a certain amplitude.

[0063] Step 6: Control the piston rods of the second telescopic cylinders 29 of the four groups of clamping mechanisms 9 to extend simultaneously, so that the telescopic rods 28 become longer and the clamping jaws 31 move outward. Then control the piston rod of the rotation cylinder 30 to contract, and the telescopic rod 28 starts to rotate downward, and the clamping jaws 31 descend to the outside of the edge of the steel plate 32. Then control the piston rods of the second telescopic cylinders 29 to contract, so that the clamping jaws 31 move to the outer edge of the steel plate 32. Then control the suction cup body 27 to cut off the air and lose the adsorption force, and the suction cup body 27 is no longer connected to the steel plate 32, and the steel plate 32 drops by a certain amplitude and contacts the clamping jaws 31. Finally, control the second telescopic cylinders 29 and the rotation cylinders 30 to contract simultaneously, so that the clamping jaws 31 tightly clamp the edge of the steel plate 32. Thus, the steel plate 32 is stably clamped.

[0064] Step 7: Control the piston rod of the lifting cylinder 5 to continue to contract, so that the steel plate 32 rises to the moving height.

[0065] Step 8: Control the movement of the steel plate 32 by holding the control handle 34 until the steel plate 32 moves above the blanking point. Then control the piston rod of the lifting cylinder 5 to extend, and the steel plate 32 starts to descend until the steel plate 32 falls to the blanking point.

[0066] Step 9: Control the piston rods of the second telescopic cylinder 29 and the rotating cylinder 30 to extend simultaneously, so that the clamping jaws 31 are disengaged from the steel plate 32. The lifting of the steel plate 32 is completed.
