[0023] It should be noted that the hydraulic pump 7 and the tractor 6 are existing technologies, and the specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0024] Furthermore, the double lifting support structure includes a limit bolt 8, a rotating rod 9, a first bevel gear 10, a second bevel gear 11, a coarse screw 12, a coarse slide rod 13, a connecting plate 14, an operating port 15, a slide groove 16, a slider 17, a bearing 18, a roller 19, and a wheel 20. The limit bolt 8 is slidably connected to the turntable 5 and is threadedly connected to the outer wall of the fixed platform 1.

[0025] A hole is provided on the outer wall of the turntable 5, and the limit bolt 8 is slidably connected to the hole. A threaded hole is provided on the outer wall of the fixed platform 1, and the limit bolt 8 is threadedly connected to the threaded hole. The hole and the threaded hole are coaxially arranged.

[0026] Furthermore, one end of the rotating rod 9 is fixedly connected to the turntable 5, the other end of the rotating rod 9 is fixedly connected to the first bevel gear 10, the second bevel gear 11 is rotatably connected to the bottom end of the inner wall of the storage chamber 4, and the first bevel gear 10 and the second bevel gear 11 are meshed with each other.

[0027] The other end of the rotating rod 9 penetrates the outer wall of the fixing platform 1 and is rotatably connected.

[0028] Furthermore, the top end of the second bevel gear 11 is fixedly connected to the bottom end of the coarse screw 12, the top end of the coarse screw 12 is rotatably connected to the top end of the inner wall of the storage chamber 4, the coarse sliding rod 13 is fixedly connected to the inner wall of the storage chamber 4, and the front and rear ends of the connecting plate 14 are slidably connected to the inner wall of the storage chamber 4.

[0029] Among them, the connecting plate 14 is threadedly connected to the coarse screw 12, and the connecting plate 14 is slidably connected to the coarse sliding rod 13, so that the rotation of the coarse screw 12 drives the connecting plate to rise and fall, and then drives the roller 19 to move up and down, so that recycling can be easily carried out.

[0030] Furthermore, the running port 15 is arranged at the top of the fixed platform 1 and is symmetrically distributed, the slide groove 16 is arranged on the inner wall of the storage cavity 4 and is evenly distributed, the slider 17 is slidably connected to the slide groove 16, and the connecting plate 14 is fixedly connected to the outer wall of the slider 17.

[0031] When the connecting plate 14 reaches the top position, it will abut against the outer wall of the fixing platform 1. At this time, the roller 19 is in a protruding position, which is convenient for testing.

[0032] Furthermore, the outer wall of the slider 17 is fixedly connected to the bearing 18 , and both sides of the rollers 19 are fixedly connected to the bearing 18 , and the rollers 19 are evenly distributed in the circumferential direction.

[0033] The two rollers 19 are parallel to each other. Under the action of the bearing 18, when a rotational force is applied to the roller 19 from the outside, the roller 19 can rotate more easily, thereby greatly reducing the friction resistance.

[0034] Furthermore, the wheel 20 abuts against the outer wall of the drum 19, and the wheel 20 is disposed at the bottom of the tractor.

[0035] Among them, the hydraulic pump 7 exists independently. When the connecting plate 14 is driven to the top by the thick screw 12, the hydraulic pump 7 can be started so that its telescopic end is against the bottom end of the outer wall of the connecting plate 14, playing a double support role to prevent the thick screw 12, the connecting plate 14, etc. from being damaged due to the excessive weight of the tractor 6.

[0036] Working principle: First, before the test, it is necessary to manually rotate the turntable 5, the turntable 5 drives the rotating rod 9 to rotate, the rotating rod 9 drives the first bevel gear 10 to rotate, the first bevel gear 10 drives the second bevel gear 11 to rotate, the second bevel gear 11 drives the coarse screw 12 to rotate, the coarse screw 12 drives the connecting plate 14 to move up and down along the coarse slide rod 13, so the connecting plate 14 drives the slider 17 to move, the slider 17 drives the bearing 18 and the roller 19 to move up and down in the running port 15, after reaching the appropriate position, the hydraulic pump 7 can be started to make its telescopic end against the bottom end of the outer wall of the connecting plate 14, which plays a double support role to avoid the excessive weight of the tractor 6 causing damage to the coarse screw 12, the connecting plate 14, etc., finally, the tractor 6 is driven from the ramp 3 to the top of the fixed platform 1, the wheel 20 is parked between the roller 19, and the test can be carried out, so that the roller is more stable under the heavy pressure of the tractor during the test, and will not collapse easily, and can be easily retracted into the fixed platform when not in use, avoiding the situation where it is placed in the outside for a long time and is damaged.
