Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a sling for transferring steel plates. Background Art

[0002] In the processing of steel plates, small steel plates can be loaded and unloaded manually by workers. However, for heavier steel plates, manual loading and unloading is not only inefficient, but also poses great safety hazards. Therefore, in the processing of steel plates, it is necessary to use a hoist to load and unload the steel plates. The hoist absorbs the steel plates through suction cups, and then transfers the steel plates by transferring the hoist.

[0003] Currently, most of the vacuum cups on common vacuum lifters adopt a fixed structure, which cannot meet the use requirements of steel plates of different sizes. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model provides a hanger for transferring steel plates.

[0005] The utility model proposes a lifting device for transferring steel plates, comprising: a first rod body, two second rod bodies, a first slider, a first suction cup, and an adjusting mechanism, wherein a hook is installed at the top end of the first rod body, the two second rod bodies are horizontally arranged and vertically fixed to the bottom end of the first rod body, the adjusting mechanism has two groups, one group of adjusting mechanisms is connected with two first sliders slidably sleeved on one of the second rod bodies to drive the two first sliders to move closer to or away from each other, and the other group of adjusting mechanisms is connected with two first sliders slidably sleeved on the other second rod body to drive the two first sliders to move closer to or away from each other, and the first suction cup is fixed to the bottom end of the first slider.

[0006] Preferably, the adjustment mechanism includes a second slider, two driving rods, and a locking mechanism. The second slider is vertically slidably mounted on the first rod body.

[0016] Reference Figure 1 The utility model proposes a steel plate transfer hanger, comprising: a first rod body 1, two second rod bodies 2, a first slider 3, a first suction cup 4, and an adjusting mechanism 5. A hook is installed at the top of the first rod body 1, and the two second rod bodies 2 are arranged horizontally and fixed vertically to the bottom end of the first rod body 1. The adjusting mechanism 5 has two groups, one group of adjusting mechanisms 5 is connected with the two first sliders 3 slidably sleeved on one of the second rod bodies 2 to drive the two first sliders 3 to move closer to or away from each other, and the other group of adjusting mechanisms 5 is connected with the two first sliders 3 slidably sleeved on the other second rod body 2 to drive the two first sliders 3 to move closer to or away from each other, and the first suction cup 4 is fixed to the bottom end of the first slider 3.

[0017] When in use, the adjusting mechanism 5 adjusts the distance between the two first sliders 3 located on the same second rod body 2. The two first sliders 3 and the first suction cup 4 located on one of the second rod bodies 2 fix the steel plate in the length direction of the steel plate, and the two first sliders 3 and the first suction cup 4 located on the other second rod body 2 fix the steel plate in the width direction of the steel plate. In addition to being able to fix the four edges of the steel plate, it can also meet the transfer and use requirements of steel plates of different widths and lengths.

[0018] During adjustment, the adjustment mechanism 5 can simultaneously drive the two first sliders 3 located on the same second rod body 2 to move. Compared with the method of moving and adjusting a single suction cup in the prior art, this method is simpler, faster and more efficient in adjustment.

[0019] In the above embodiment, the adjustment mechanism 5 can be specifically a two-way cylinder arranged in parallel with the second rod body 2. The two output ends of the two-way cylinder are respectively connected to the two first sliders 3. When the two-way cylinder is extended, the two first sliders 3 are driven away from each other. When the two-way cylinder is shortened, the two first sliders 3 are driven towards each other. However, this method may cause the second rod body 2 to have poor bearing capacity away from the end of the first rod body 1, and the entire sling may not be strong enough.

[0020] In order to make the sling more secure, the adjusting mechanism 5 in the sling proposed by the utility model includes a second slider 51, two driving rods 52, and a locking mechanism 53. The second slider 51 is vertically slidably sleeved on the first rod body 1, the top ends of the two driving rods 52 are rotatably connected to the second slider 51, and the bottom ends of the driving rods 52 are respectively rotatably connected to the corresponding two first sliders 3. The locking mechanism 53 is installed on the second slider 51 to lock the sliding of the second slider 51 on the first rod body 1.

[0021] The specific method of using the adjustment mechanism 5 is as follows: first, slide the second slider 51 along the length direction of the first rod body 1. When the second slider 51 moves up and down, the driving rod 52 drives the first slider 3 to slide along the second rod body 2, thereby adjusting the position of the first slider 3. After the position is determined, the second slider 51 is locked by the locking mechanism 53 to fix the first slider 3. When in use, the bottom end of the driving rod 52 can also provide an upward pulling force to the first slider 3, forming a more stable triangular structure between the driving rod 52, the first rod body 1, and the second rod body 2, thereby making the present sling more stable.

[0022] It needs to be further explained that, in the prior art, the locking mechanism 53 can usually adopt a locking bolt, which is screwed on the second slider 51. The locking bolt is turned so that the locking bolt abuts against the outer wall of the first rod body 1 to lock it. However, due to the heavy weight of the steel plate, the second slider 51 may move during the transfer process, thereby affecting the use of the sling. In order to prevent the above problems from occurring when the locking mechanism 53 is in use, the locking mechanism 53 in the utility model includes a screw 531 and a block 532. A groove 11 arranged along the length direction of the first rod body 1 is provided on the first rod body 1, and a plurality of grooves 111 are sequentially provided on the two side walls of the groove 11 along the length direction of the first rod body 1. The screw 531 is horizontally rotatably installed on the second slider 51, the block 532 is screwedly connected to the screw 531, and a guide groove for the block 532 to slide horizontally is also provided on the second slider 51.

[0023] When the screw rod 531 is rotated, the block 532 is slidably plugged into the guide groove, so the block 532 will not rotate with the screw rod 531. The rotation of the screw rod 531 will drive the block 532 to move horizontally along the guide groove into the slot 111. When the block 532 enters the slot 111, the locking mechanism 53 locks the sliding of the second slider 51 on the first rod body 1. For details, refer to Figure 3 When the block 532 is disengaged from the slot 111, the second slider 51 can slide on the first rod 1 to adjust the distance between the two corresponding first sliders 3. Figure 2 .

[0024] To make the device more secure, the locking mechanism 53 includes two blocks 532 , and the screw holes on the two blocks 532 that are screwed to the screw rod 531 have opposite spiral directions. The screw rod 531 has two sections of external threads in opposite directions.

[0025] In the above embodiment, the groove body 11 horizontally penetrates the first rod body 1 .

[0026] In order to improve the adsorption force between the sling and the steel plate, a second suction cup is also installed at the bottom end of the first rod body 1.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
