After the protrusion is stuck in the limiting groove, the protrusion can no longer rotate, so that when the cargo is lifted to the top, it will not shake during lifting because the weight of the cargo is not in a balanced state, thereby preventing the cargo from shaking and falling, and improving safety during operation.

[0015] 2. In the present invention, the friction between the spring sheet and the friction plate is increased, so that when the hook moves to the bottom, it will slowly descend without shaking, ensuring that the hook will accurately contact and lift the goods, thereby improving the stability of the device. After the friction plate moves, it will no longer contact the spring sheet, so that the device will not be affected by deceleration when moving to the top, preventing the device from being overloaded and damaged due to excessive resistance after lifting the goods, thereby improving the protection effect of the device. After the friction plate moves, the reset telescopic rod is reset to drive the limit plate to re-limit the friction plate, so that when the device completes the work, the entire device will return to the initial state, without hindering the device from performing deceleration work again, thereby improving the practicality of the device.

[0016] 3. In the present invention, after the transmission block moves, the arc rod will be reset through the No. 3 spring reset, thereby preventing the steel cable from shaking due to increased tension and stress after the hook lifts the goods, reducing the shaking amplitude, ensuring that the steel cable will not break, and ensuring the stability of the device during operation. After the steel cable shakes, the damping spring resets to smooth out the shaking, further reducing the shaking amplitude and improving the practicability of the device.

The fixing rod 66 is fixedly passed through the baffles 65. The sliding wheel 67 is slidably installed on the opposite side of the baffle 65, and the hook 61 is fixedly installed on the circumferential surface of the sliding wheel 67. It is convenient and quick. The staff only needs to press a button to complete the operation, saving time and improving work efficiency. The protrusion 68 is fixedly installed on the circumferential surface of the sliding wheel 67, and the limiting groove 69 is opened on the opposite side of the baffle 65, so that when the goods are lifted to the top, they will not shake during lifting due to the weight of the goods being not in a balanced state, thereby preventing the goods from shaking and falling, thereby improving safety during operation.

[0021] A No. 1 spring is arranged between the sliding wheel 67 and the baffle 65 , and the protrusion 68 contacts the limiting groove 69 , and the sliding wheel 67 is driven to reset by the No. 1 spring.

[0022] The control button 1 3 is electrically connected to the driving device 5 , and the control button 2 4 is electrically connected to the hydraulic rod 610 , and the driving device 5 is started by the control button 1 3 .

After the driving device 5 moves to the desired position, the control button 24 is pressed to start the output end of the hydraulic rod 610 to move toward the bottom. The output end of the hydraulic rod 610 moving toward the bottom will drive the guide block 62 to move toward the bottom. The guide block 62 moving toward the bottom will drive the steel cable 63 to move toward the bottom. The steel cable 63 moving toward the bottom will drive the guide wheel 64 to move toward the bottom. The guide wheel 64 moving toward the bottom will drive the baffle 65 to move toward the bottom. The baffle 65 moving toward the bottom will drive the sliding wheel 67 to move toward the bottom. The sliding wheel 67 moving toward the bottom will drive the hook 61 to move toward the bottom. The movement of the hook 61 toward the bottom will lift the goods placed at the bottom of the protective beam 1. It is convenient and quick. The staff only needs to press a button to complete the operation, which saves time and improves work efficiency. When the output end of the hydraulic rod 610 moves toward the top, the output end of the hydraulic rod 610 moves toward the top.

[0024] Example 2 like Figure 1 to Figure 7As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a protective device and a stabilizing device are provided at the bottom of the driving device 5, wherein the protective device includes: a hollow box 71, a reset telescopic rod 72, a limit plate 73, a friction plate 74, a spring piece 76 and a transmission plate 77.

[0025] The protective device also includes: a rotating block 78, an arc plate 79, a connecting plate 710 and a blocking block 711. The rotating block 78 is fixedly installed on the inner wall surface of the hollow box 71, the arc plate 79 is rotatably installed between the rotating blocks 78, the connecting plate 710 is fixedly installed on the circumferential surface of the output end of the hydraulic rod 610, and the blocking block 711 is fixedly installed on the circumferential surface of the output end of the hydraulic rod 610, so that when the device completes its work, the entire device will return to its initial state, which will not hinder the device from performing deceleration work again, thereby improving the practicability of the device.

The storage box 81 is fixedly installed on the top of the baffle 65, the partition 82 is fixedly installed on the inner wall of the storage box 81, one end of the damping spring 83 is fixedly installed on the inner wall of the storage box 81, and the other end of the damping spring 83 is fixedly installed on the circumferential surface of the steel cable 63, so as to further reduce the shaking amplitude and improve the practicality of the device. The square block 84 is fixedly installed on the inner wall of the partition 82 close to the steel cable 63, the transmission block 85 is slidably installed on the inner wall of the square block 84, and the arc rod 86 is fixedly installed on the side of the transmission block 85 away from the square block 84, so as to prevent the steel cable 63 from shaking due to the increase of tension and stress after the hook 61 lifts the goods, reduce the shaking amplitude, ensure that the steel cable 63 will not break, and ensure the stability of the device during operation.

[0029] When the output end of the hydraulic rod 610 moves toward the bottom, it will drive the spring plate 76 to move toward the bottom. The spring plate 76 moves toward the bottom and contacts with the friction plate 74. The spring plate 76 will be deformed after contacting with the friction plate 74. The deformation of the spring plate 76 will increase the contact area with the friction plate 74, so that the friction between the spring plate 76 and the friction plate 74 is increased, so that when the hook 61 moves toward the bottom, it will slowly descend without shaking, ensuring that the hook 61 will accurately contact and lift the cargo, thereby improving the stability of the device. When the output end of the hydraulic rod 610 moves toward the bottom, it will drive the transmission plate 77 to move toward the bottom. The transmission plate 77 moves toward the bottom and contacts with the limit plate 73. The transmission plate 77 moves toward the bottom and pushes the limit plate 73 to move toward the bottom. After the limit plate 73 moves toward the bottom, it no longer limits the friction plate 74, and the friction plate 74 is reset by the second spring 75, driving the friction plate 74 to move away from the spring plate 7 6, the friction plate 74 no longer contacts the spring piece 76 after moving, so that the device will not be affected by the deceleration when moving to the top, thereby preventing the device from being overloaded and damaged due to excessive resistance after lifting the cargo, thereby improving the protection effect of the device, and the output end of the hydraulic rod 610 will drive the connecting plate 710 to move to the top when it moves to the top, and the connecting plate 710 will contact the arc plate 79 when it moves to the top, and the connecting plate 710 will be blocked by the blocking block 711 so that the connecting plate 710 cannot rotate to the bottom, and the connecting plate 710 moving to the top will push the arc plate 79 to rotate, and the rotation of the arc plate 79 will drive the friction plate 74 to move in the direction of the spring piece 76, and after the friction plate 74 moves, it will reset through the resetting telescopic rod 72 to drive the limit plate 73 to re-limit the friction plate 74, so that when the device completes the work, the overall device will return to the initial state, without hindering the device from performing the deceleration work again, thereby improving the practicality of the device.

[0030] When the steel cable 63 lifts the cargo, the steel cable 63 will shake and contact the arc rod 86. The movement of the steel cable 63 will push the arc rod 86 to move. The movement of the arc rod 86 will drive the transmission block 85 to move toward the outer wall of the placement box 81. After the transmission block 85 moves, it will drive the arc rod 86 to reset through the No. 3 spring to prevent the steel cable 63 from shaking due to increased tension and stress after the hook 61 lifts the cargo, reduce the shaking amplitude, ensure that the steel cable 63 will not break, and ensure the stability of the device during operation. After the steel cable 63 shakes, the damping spring 83 will reset to smooth the shaking, further reduce the shaking amplitude, and improve the practicability of the device.
