Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, and particularly relates to a steel plate lifting tool. Background Art

[0002] In steel structure and steel plate processing, in order to save storage space, steel plates are usually placed in a side-standing manner. Therefore, when taking steel plates, side / vertical lifting is also adopted, including flanging, tilting lifting or stacking of steel plates. At this time, a steel plate flipping lifting tool is required. For example, the utility model patent multifunctional electro-permanent magnetic lifting tool with the publication number CN204569123U; the utility model patent an electromagnetic lifting tool with adjustable angle with the publication number CN206615916U; the characteristics of such lifting tools are that the suction cups are hinged to the lower side of the lifting beam, so that the suction cups can adsorb on one side edge of the steel plate for side / vertical lifting of the steel plate.

[0003] In order to avoid the inclination of both ends of the steel plate during side / vertical lifting of the steel plate, ensure the balance of both ends of the steel plate and the uniform force at each lifting point, the suction cups should be aligned and placed on the edge of the steel plate, that is, the connection line of the suction cups should be parallel to the edge of the steel plate, and then the adsorption connection is carried out. Manually adjusting the position of the suction cups is dangerous, inefficient, and the accuracy of the position is not high only by visual observation. Summary of the Utility Model

[0026] The present utility model will be further described in detail below in conjunction with embodiments.

[0027] Specific embodiments of the steel plate hoisting sling provided by the present utility model:

[0028] Please refer to Figures 1-6 , the steel plate hoisting sling, including a lifting beam 1; a lifting ring 7 is arranged above the middle of the lifting beam 1, and the lifting ring 7 is connected to the lifting beam 1 through a plurality of suspension ropes 8. The suspension ropes 8 can be steel ropes or lifting chains; the lifting ring 7 is used for hooking the hook of the hoisting power equipment.

[0029] In some embodiments, warning sound and light lamps can be installed on the upper sides of both ends of the lifting beam 1, which are used to emit warning sound and light information during the hoisting process to ensure the safety of hoisting.

[0030] A plurality of suspension rods 5 are evenly arranged on the lifting beam 1, and the lower ends of the suspension rods 5 are located on the lower side of the lifting beam 1; in some other embodiments, the suspension rods 5 can be provided with vertical elastic supports.

[0031] A plurality of hanging brackets 6 are provided on the lower side of the lifting beam 1, and the shape of the hanging brackets 6 is an inverted U shape. The upper ends of the hanging brackets 6 are connected to the suspension rods 5, and the lower ends are respectively hinged to the suction cup assemblies 2.

[0032] In this embodiment, the suction cup assembly 2 includes a mounting shell 21 and a suction cup body 22. The mounting shell 21 is hinged to the hanger 6 on the lower side of the hanging beam 1, and the suction cup body 22 is embedded and installed on the lower side of the mounting shell 21. The suction cup body 22 adopts an electromagnetic suction cup; the suction cup body 22 is connected to the power supply line, the power supply line passes through the mounting shell 21, and a distribution box is set to connect the power supply line to realize power supply control; the power supply of the electromagnetic suction cup is a prior art and is not the focus of this embodiment, and the power supply equipment is not shown in the figure.

[0033] A limiting member 3 is provided at the same end of the suction cup assembly 2. In the present embodiment, the limiting member 3 includes a connecting portion 31 and a limiting portion 32. The limiting member 3 is an L-shaped plate structure. The connecting portion 31 and the limiting portion 32 are respectively provided on both sides of the corner of the L-shaped plate structure. The limiting portion 32 is connected to the end of the suction cup assembly 2 through the connecting portion 31.

[0034] In the present embodiment, the connecting portion 31 is connected to the mounting shell 21 of the suction cup assembly 2 by means of bolts 4; two bolts 4 are passed through the connecting portion 31, and a plurality of positioning holes 33 for the bolts 4 to pass through are arranged along the connecting portion 31 away from the suction cup assembly 2, the positioning holes 33 are arranged in groups of two, and a plurality of groups are arranged, and each group corresponds to two bolts 4; in the present embodiment, threaded holes 23 cooperating with the bolts 4 are arranged at both ends of the mounting shell 21.

Threaded holes 23 are provided at both ends of the mounting shell 21. When the steel plate 9 needs to be placed upright to the other side and the other edge of the steel plate 9 needs to be sucked, the stopper 3 can be uniformly installed at the other end of the suction cup assembly 2.

[0036] When the bolts 4 are passed through different groups of positioning holes 33, the distances between the limiting portion 32 and the end of the suction cup assembly 2 are different, so that the distance between the limiting portion 32 and the end of the suction cup assembly 2 can be adjusted, so that the suction cup assembly 2 can be adsorbed at different distances from the edge of the steel plate 9, but the protruding lengths of the limiting portions 32 of each limiting member 3 should be consistent.

[0037] During lifting, the lifting power equipment causes the hanging beam 1 to fall, and the suction cup assembly 2 falls on the edge of the steel plate 9. At this time, it is not necessary to require the position of each suction cup assembly 2 to be accurate, and it is also OK for the hanging beam 1 to be relatively tilted relative to the edge of the steel plate 9. Then, the lifting power equipment causes the hanging beam 1 and the suction cup assembly 2 to move toward the center of the steel plate 9, and the suction cup assembly 2 moves along the surface of the steel plate 9 until the limiting parts 32 of the limiting member 3 all abut against the edge of the steel plate 9. At this time, each suction cup assembly 2 is aligned and neatly located at the edge of the steel plate 9, and then the suction cup body 22 is started to generate suction, and the suction cup assembly 2 is adsorbed on the side of the steel plate 9, and the limiting part 32 abuts against the outer side of the edge of the steel plate 9; then the lifting power equipment causes the hanging beam 1 and the suction cup assembly 2 to lift, which can drive the steel plate 9 to move upward and realize the side vertical lifting of the steel plate 9.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
