Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and in particular relates to a hot-dip galvanizing hanger with adjustable spacing. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetic purposes and to prevent rust. It requires a process of water washing, pickling, solvent immersion, hot-dip galvanizing, passivation, rinsing and other processes. In this set of processes, hoists are required to lift the materials to be galvanized to each process.

[0003] For example, a Chinese patent (publication number: CN202021247907.5) discloses a sling with adjustable spacing. Although the spacing between the hooks is adjustable, which improves the applicability of the sling for materials of various specifications to be hoisted, the size of the sling cannot be reduced during the adjustment process, so that the size of the lifting beam in the sling is fixed, and the hoisting size is large, making the device inconvenient to carry. Therefore, a hot-dip galvanized sling with adjustable spacing is needed to solve the above problems. Utility Model Content

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] See also Figure 1-3 The utility model provides a hot-dip galvanizing hanger with adjustable spacing, comprising a fixed shell 1, a plurality of first rotating rods 10 and a plurality of second rotating rods 11. The number of fixed shells 1 is two, and the upper surfaces of the two fixed shells 1 are connected to the lifting ring 2. The same multi-stage telescopic rod 3 is connected between the two lifting rings 2. The multi-stage telescopic rod 3 is arranged above the two fixed shells 1. By setting the multi-stage telescopic rod 3, the multi-stage telescopic rod 3 can limit the two moving fixed shells 1, so that the two fixed shells 1 can move smoothly along the axial direction of the multi-stage telescopic rod 3.

[0021] A threaded rod 4 is rotatably connected inside one of the fixed shells 1, and the threaded rod 4 is externally threadedly connected to two threaded blocks 5. The threaded rod 4 is composed of two threaded columns with opposite thread directions, and the two threaded blocks 5 are both threadedly connected to the outside of the threaded columns. The bottom end of the threaded rod 4 is connected to the motor 6, and the motor 6 is connected to the side of one of the fixed shells 1 through a connecting frame 18. By setting the connecting frame 18, the connecting frame 18 can fix the motor 6 below the fixed shell 1;

[0022] Another fixed shell 1 is connected with a guide rod 7, and two guide blocks 8 are slidably connected outside the guide rod 7. The two threaded blocks 5 and the two guide blocks 8 are connected to the connecting block 9 on their adjacent sides. The threaded block 5 is overlapped in the fixed shell 1, and the guide block 8 is overlapped in the fixed shell 1. The shapes of the threaded block 5 and the guide block 8 are both set to be rectangular. By providing the threaded block 5 and the fixed shell 1, since the threaded block 5 is slidably connected in the fixed shell 1, the fixed shell 1 can limit the threaded rod 4, so that the threaded block 5 is not easy to rotate under the action of rotating the threaded rod 4, so that the threaded block 5 can move smoothly along its axial direction under the action of rotating the threaded rod 4;

[0023] The two connecting blocks 9 on both sides are respectively hinged to the two first rotating rods 10 and the two second rotating rods 11 through the pin shaft 12, and the two ends of the first rotating rods 10 and the second rotating rods 11 are hinged through the pin shaft 12, and the middle parts of the first rotating rods 10 are respectively hinged to the middle parts of the second rotating rods 11 through the pin rod 13, and the two ends of the pin rod 13 are connected to the winding roller 14, and the winding rollers 14 are connected to the connecting rope 16. The bottom ends of every two connecting ropes 16 are connected to the same hook 17. By setting the winding roller 14, the rotating winding roller 14 can wind up the connecting rope 16;

[0024] The front sides of the plurality of winding rollers 14 located in the front are connected to the operating block 15. By providing the operating block 15, the user can drive the winding rollers 14 to rotate around the pin rod 13 through the operating block 15;

[0026] The working principle and use process of the utility model are as follows: when the sling needs to be used, the control motor 6 drives the threaded rod 4 to rotate forward in the fixed shell 1, and the threaded rod 4 rotating forward drives the two threaded blocks 5 to approach each other in the fixed shell 1, and the two threaded blocks 5 approaching each other both drive the first rotating rod 10 and the second rotating rod 11 close to the threaded rod 4 to rotate around the pin rod 13 through the fixed block, so that the first rotating rod 10 and the second rotating rod 11 rotating on the other side both drive the two guide blocks 8 to slide outside the guide rod 7 through the pin shaft 12 and the fixed block, and at this time, the two fixed shells 1 moving away from each other drive the multi-stage telescopic rod 3 to extend, and at the same time, the distance between the several pin rods 13 increases, and the several pin rods 13 drive the distance between the several hooks 17 to increase through the winding roller 14 and the connecting rope 16;

[0027] Similarly, the control motor 6 is reversed, the two fixed shells 1 approach each other, the multi-stage telescopic rod 3 contracts, and the distance between the plurality of hooks 17 becomes smaller.
