Description

Technical Field

[0001] The utility model relates to the technical field of steel component transportation, in particular to a multi-point lifting device for H-shaped steel components. Background Art

[0002] The H-shaped steel component is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio, and it gets its name because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel component are arranged at right angles, the H-shaped steel component has the advantages of strong bending resistance in all directions, simple construction, cost saving, and light structural weight, and has been widely used.

[0003] Currently, when lifting H-shaped steel components, it is generally lifted by a traveling crane in cooperation with a lifting tool. During the lifting process, it is necessary to clamp the H-shaped steel. The existing technologies all clamp multiple clamping tools separately, which cannot ensure that each clamping tool is evenly stressed, and single clamping is relatively laborious. Generally, it is directly lifted after clamping, and it is impossible to confirm whether the self-weight of the H-shaped steel exceeds the load of the traveling crane. If overloaded, serious accidents are likely to occur. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that need to be solved in the above background art, and to propose a multi-point lifting device for H-shaped steel components.

A connecting ring is rotatably connected in the mounting ring. Three inverted U-shaped plates are evenly and fixedly connected to the lower surface of the hanging plate. A bidirectional lead screw is rotatably connected through both side walls of the three inverted U-shaped plates. One end of the bidirectional lead screw is fixedly connected with a sprocket. One end of one of the bidirectional lead screws is fixedly connected with a knob. Clamping blocks are symmetrically threadedly connected to both ends of the bidirectional lead screw. A rubber sheet is fixedly connected to the inner side of the clamping block. A fixing plate is fixedly connected to the lower surface of the clamping block.

[0007] Preferably, a hanging ring is fixedly connected to the upper surface of the weight display, and the weight display and the connecting ring are connected by a steel wire rope.

[0008] Preferably, the sprockets are connected by chain drive.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0019] Refer to Figures 1 - 3, a multi-point lifting device for H-shaped steel members, comprising a lifting plate 1, a steel wire rope 6, a weight display 7, an H-shaped steel 9 and a chain 20. It is characterized in that three mounting sleeves 3 are evenly and fixedly connected to the upper surface of the lifting plate 1. An installation ring 4 is threadedly connected inside the three mounting sleeves 3. A connecting ring 5 is rotatably connected inside the installation ring 4. Threadedly connecting the installation ring 4 with the mounting sleeve 3 is for the convenience of disassembling and assembling the installation ring. A lifting ring 8 is fixedly connected to the upper surface of the weight display 7. The weight display 7 and the connecting ring 5 are connected by a steel wire rope 6. By setting the weight display 7, it is possible to constantly detect whether the weight of the H-shaped steel 9 exceeds the lifting range to prevent overloading.

[0020] In the present utility model, three inverted U-shaped plates 2 are evenly and fixedly connected to the lower surface of the lifting plate 1. A bidirectional lead screw 10 is rotatably connected through both side walls of the three inverted U-shaped plates 2. One end of the bidirectional lead screw 10 is fixedly connected to a sprocket 14. The sprockets 14 are chain-driven by a chain 20. One end of one of the bidirectional lead screws 10 is fixedly connected to a knob 13. Clamping blocks 11 are symmetrically threadedly connected to both ends of the bidirectional lead screw 10. A rubber sheet 19 is fixedly connected to the inner side of the clamping blocks 11. A fixing plate 15 is fixedly connected to the lower surface of the clamping blocks 11. Two sliding rods 12 are slidably connected through the clamping blocks 11. Both ends of the two sliding rods 12 are fixedly connected inside the inner side wall of the inverted U-shaped plate 2. The two sliding rods 12 are located below the bidirectional lead screw 10. By rotating the knob 13, one of the bidirectional lead screws 10 rotates. Since one end of the bidirectional lead screw 10 is fixedly connected to a sprocket 14 and the sprockets 14 are chain-driven by a chain 20, the three bidirectional lead screws 10 will rotate simultaneously. Since the two ends of the bidirectional lead screw 10 are threadedly connected to the clamping blocks 11, the clamping blocks 11 on both sides move relatively. Then, in cooperation with the sliding rods 12, the clamping blocks 11 play a clamping role. By setting a chain drive device, multiple clamping blocks can simultaneously clamp the H-shaped steel to prevent accidents caused by uneven stress during work.

[0021] In the present utility model, moving rods 16 are symmetrically slidably connected through the upper surface of the fixing plate 15. A spring 17 is slidably connected to the annular side surface of the moving rods 16. A backing plate 18 is fixedly connected to the upper surface of the moving rods. One end of the spring 17 is fixedly connected to the upper surface of the fixing plate 15, and the other end of the spring 17 is fixedly connected to the lower surface of the backing plate 18. Both side surfaces of the H-shaped steel 9 are in contact with the rubber sheet 19, and one side surface of the H-shaped steel 9 is in contact with the upper surface of the backing plate 18. When the H-shaped steel 9 is seated on the upper surface of the backing plate 18, the gasket 18 will drive the moving rod 16 to move downward, and at the same time compress the spring 17, thus playing a buffering role for the H-shaped steel.

[0022] The functional principle of the present utility model can be described by the following operation method:

[0023] When one surface of the H-shaped steel 9 is in contact with the backing plate 18 and the H-shaped steel 9 is located on the upper surface of the backing plate 18, the backing plate 18 will drive the moving rod 16 to move downward, and at the same time compress the spring 17, thereby playing a buffering role for the H-shaped steel. At this time, manually rotate the knob 13. By rotating the knob 13, one of the double lead screws 10 rotates. Since one end of the double lead screw 10 is fixedly connected with a sprocket 14, and the sprockets 14 are connected by chain drive through a chain 20, the three double lead screws 10 will rotate simultaneously. Since the two threads of the double lead screw 10 are connected with clamping blocks 11, the clamping blocks 11 on both sides move relatively, and the clamping blocks 11 play a clamping role in cooperation with the slide rod 12. After the H-shaped steel 9 is fixed, start the overhead crane to lift the H-shaped steel 9. At this time, it is necessary to observe the number on the weight display 7 to check whether the weight is overloaded. If it is overloaded, stop working. If it is not overloaded, continue to work. By setting the chain drive device, multiple clamping blocks 11 can clamp the H-shaped steel 9 at the same time, preventing accidents caused by uneven force during work. By setting the weight display, the weight of the H-shaped steel can be detected at all times to prevent overloading.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
