[0002] In the shipbuilding industry, the lifting operation of steel plates is an indispensable and important part of the production process. The traditional steel plate lifting method usually relies on simple lifting equipment and manual operation. This operation method is not only inefficient, but also has many safety hazards. For example, during the steel plate lifting process, due to the lack of sufficient stability and precision of the lifting equipment, the steel plate is prone to large swings and shaking, which not only increases the difficulty of operation, but also may cause the steel plate to fall accidentally, posing a serious threat to workers and equipment on the production line. In order to overcome the shortcomings of the traditional steel plate lifting method, the industry has begun to explore more efficient and safe lifting technologies and equipment. However, although the existing steel plate lifting equipment has improved the operating efficiency to a certain extent, it still has shortcomings in stability and safety. Although some equipment is equipped with a clamping mechanism, the clamping force and stability are often difficult to guarantee, especially when lifting large or heavy steel plates, the problem is particularly prominent.

The proximity switch 309 is a prior art and will not be described in detail here. When the proximity switch 309 is close to the induction baffle 2, the motor 305 can be prompted to turn off.

[0034] Furthermore, if Figure 5 , Fig. 9 and Fig.10As shown, the stabilizing mechanism 4 includes: a second connecting rod 41, a second slider 42, a hanging plate 43, a second slide groove 44, a second guide rod 45, a pulley 46, a pull rope 47, a telescopic rod 48, an extrusion wheel 49, a spring 410 and a pressure plate 411. The number of the second connecting rods 41 is four, and the top ends of the four second connecting rods 41 are rotatably arranged at the front and rear sides of the middle part of the bottom end of the hanging beam 301 through pins. The second connecting rod 41 can ensure that the hanging plate 43 and the hanging beam 301 are relatively stable. The second slider 42 is rotatably arranged at the bottom end of the second connecting rod 41 through a pin. Second slide grooves 44 are opened at the front and rear ends of the left and right sides of the top of the hanging plate 43 along the left and right directions. The second sliders 42 are slidably adapted and inserted into the outer sides of the inner cavities of the four second slide grooves 44, respectively. The top ends of the four third connecting rods 55 are rotatably arranged on the left and right sides of the bottom end of the hanging plate 43 through pin shafts, and the left and right ends of the second guide rod 45 are respectively arranged on the left and right sides of the inner cavity of the second slide groove 44. The second slider 42 is slidably sleeved on the outer wall of the second guide rod 45, and the second guide rod 45 can prevent the second slider 42 from escaping from the inner cavity of the second slide groove 44. There are two pulleys 46, and the two pulleys 46 are rotatably arranged on the left and right sides of the top end of the hanging plate 43 through bearings, respectively. The pulleys 46 are used to reduce the friction between the pull rope 47 and the hanging plate 43, and the pull rope The two ends of 47 are respectively arranged on the left and right sides of the bottom end of the hanging beam 301, the outer wall of the pull rope 47 is overlapped on the outer walls of the two pulleys 46, the pull rope 47 is used to squeeze the telescopic rod 48 to move downward, the number of the telescopic rod 48 is two, the two telescopic rods 48 can be slidably adapted and plugged into the left and right sides of the top of the hanging plate 43 and the left and right sides of the top of the hanger 51, the bottom ends of the two telescopic rods 48 can be slidably extended out of the left and right sides of the bottom end of the hanger 51, the outer wall of the pull rope 47 passes through the inner cavity of the two telescopic rods 48, the telescopic rod 48 is used to drive the pressing plate 411 to move downward, the left and right sides of the top of the pressing plate 411 are respectively arranged at the bottom ends of the two telescopic rods 48, Plate 411 is used to compress and fix the steel plate placed on the pad. The extrusion wheel 49 is rotatably set in the inner cavity of the telescopic rod 48 through a bearing. The outer wall of the pull rope 47 is overlapped on the top of the outer wall of the extrusion wheel 49. The extrusion wheel 49 is used to reduce the friction between the pull rope 47 and the telescopic rod 48. The spring 410 is sleeved on the outer wall of the telescopic rod 48. The top of the spring 410 is clamped on the top of the outer wall of the telescopic rod 48. The bottom end of the spring 410 is clamped on the top of the hanging plate 43. The spring 410 is a rotary spring. After being squeezed or stretched by external force, it undergoes elastic deformation and returns to its initial state after the external force is removed. The spring 410 is used here to push the telescopic rod 48 to return to its initial position.

[0035] The working principle includes the following steps: Step 1: First, install the electric hoist 1 on the set guide rail, place the steel plate to be transported on the pad, start the electric hoist 1 to move, until the electric hoist 1 moves to a suitable position, and corresponds to the position of the pad with the steel plate, start the electric hoist 1 to release the wire, and then move downward under the gravity of the stabilizing mechanism 3, the stabilizing mechanism 4 and the clamping mechanism 5, until the clamping claw 53 moves to a suitable position, so that the four clamping claws 53 are respectively located at the front and back sides and the left and right ends of the pad, and the four clamping claws 53 are inserted into the sockets of the pad; Step 2, start the electric hoist 1 to pull the hanging beam 301 upward. When the hanging beam 301 moves upward, the two ends of the pull rope 47 are pulled to move upward. At the same time, under the gravity factors of the stabilizing mechanism 4, the clamping mechanism 5 and the pad, the outer wall of the pull rope 47 can squeeze the telescopic rod 48 to move downward, and squeeze the spring 410 to elastically deform. The downward movement of the telescopic rod 48 can drive the pressure plate 411 to move downward. At the same time, since the pull rope 47 is in a gradually straightened state, the distance between the hanging beam 301 and the hanging plate 43 will gradually increase. At this time, the second sliding block 42 can be pulled under the left and right of the second connecting rod 41 to slide inward along the inner cavity of the second sliding groove 44 until the bottom end of the pressure plate 411 contacts the steel plate placed above the pad. At this time, since the telescopic rod 48 can no longer drive the pressure plate 411 to move downward, the distance between the hanging beam 301 and the hanging plate 43 cannot continue Increase, and at the same time, since there is a certain distance between the bottom end of the hanger 51 and the top end of the pressure plate 411 at this time, the hanging plate 43 can be pulled upward by the hanging beam 301 under the action of the pull rope 47. At the same time, under the gravity factor of the clamping mechanism 5 and the pad, the position of the clamping mechanism 5 remains unchanged. Since the hanging plate 43 moves upward, the four clamping claws 53 can be pulled gradually inward under the action of the third connecting rod 55 and the fourth connecting rod 56 until the four clamping claws 53 can no longer move. At the same time, since the hanging plate 43 drives the pressure plate 411 to move upward through the telescopic rod 48, the pressure plate 411 does not contact the steel plate, and the above action is repeated until the bottom end of the pressure plate 411 contacts the steel plate again. Therefore, the electric hoist 1 can be used to drive the pad with the steel plate to move upward through the stabilizing mechanism 3, the stabilizing mechanism 4 and the clamping mechanism 5 until it moves to a suitable height; Step three, start the motor 305, and use the output end of the motor 305 to drive the forward and reverse threaded screw 304 to rotate. The rotation of the forward and reverse threaded screw 304 drives the two first sliders 306 to move inward synchronously. The two first sliders 306 move inward synchronously, and the sleeve 308 can be pushed upward along the outer wall of the electric hoist 1 through the first connecting rod 307 until the proximity switch 309 senses the sensing baffle 2, and then the motor 305 is turned off to stop the movement of the first slider 306. At this time, start the electric hoist 1 to drive the pad to move, so as to reduce the swing amplitude of the pad.

[0036] To sum up, this device can significantly improve the stability and safety of steel plate lifting process, effectively avoid the swaying, shaking and accidental falling of steel plates in traditional transportation methods, thereby greatly reducing the difficulty of operation, reducing safety hazards, and ensuring the continuous and efficient operation of the production line. At the same time, it reduces material loss and equipment damage, significantly reduces the company's operating and maintenance costs, promotes the maximum recycling of resources, and achieves a dual improvement in economic and environmental benefits.
