Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to a 310 Z-shaped steel sling. Background Art

[0002] The 310 Z-shaped steel belongs to special-shaped steel, mainly used for manufacturing railway vehicles. The product has a complex cross-section, named after the "Z" shape, and is composed of a long leg, a short leg and a waist. The characteristics are that the long leg is long and thin, the short leg is short and thick, and the waist is thin and high. The three parts are very different. The steel rail is a steel track used in the railway transportation system, usually cast from high-quality steel, with sufficient strength and durability to withstand the weight of the train and traffic pressure.

[0003] The patent document CN211470542U discloses an H-shaped steel sling, "including a load-bearing component, a rotatable tongue block, and a bolt. The characteristics are that: the load-bearing component is processed from a steel plate and includes a U-shaped stress-bearing part, an arc-shaped connecting part, and a support plate. The U-shaped stress-bearing part is inclined above the support plate and is connected to the support plate through the arc-shaped connecting part. Bolt holes are opened at the upper ends of the two ear plates of the U-shaped stress-bearing part, and a rubber plate is connected to the support plate; the rotatable tongue block is oval, with tooth marks processed on its arc-shaped surface, a connecting hole is opened in the middle, and a hoisting hole is opened at the upper end. The rotatable tongue block is connected to the load-bearing component through a bolt, and the rotating tongue block can rotate along the screw of the bolt. The utility model can effectively ensure the balance and stability during the hoisting operation of the H-shaped steel, avoid safety accidents caused by the slipping of the H-shaped steel during the hoisting process, and improve the safety of the H-shaped steel hoisting operation."

[0028] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The present utility model provides a 310 U-shaped steel sling, as Figures 1 to 6 shown, including: a lifting plate 1 and two hanging members. A hook is provided at the top of the lifting plate 1 for hanging connection with a hoisting device; the two hanging members are respectively used for hanging and fixing with the long leg and short leg of the 310 U-shaped steel 16. The two hanging members are respectively arranged on both sides of the lifting plate 1. The two hanging members can approach or move away from each other. The hanging members can extend or shorten to adapt to the height of the long leg or short leg. The two hanging members can approach or move away from each other and can move up and down in the height direction, improving the versatility of the device, facilitating finding the balance point of the trial hoisting, and thus improving the stability of the hoisting.

[0030] In a preferred embodiment, the hanging member includes an installation frame 2, two moving blocks 4, two telescopic members, and two supporting plates 9. The two moving blocks 4 are slidably connected to the installation frame 2 and can maintain their positions after sliding. The top of one telescopic member is fixedly connected to one moving block 4, and the supporting plate 9 is fixedly connected to the bottom of the telescopic member. The telescoping of the telescopic member can drive the supporting plate 9 to rise or fall.

[0031] In a preferred embodiment, the hanging member further includes a bidirectional lead screw 3. A first chute is provided at the bottom of the installation frame 2. The two ends of the bidirectional lead screw 3 are rotatably connected to the two ends of the first chute. A threaded hole is provided in the middle of the moving block 4. The two moving blocks 4 are symmetrically threadedly connected to both sides of the bidirectional lead screw. Rotating the bidirectional lead screw can drive the two moving blocks 4 to approach or move away from each other. The bidirectional lead screw 3 drives the two moving blocks 4 to rotate clockwise and counterclockwise respectively, and then the moving blocks 4 drive the two guiding frames 5 to move towards or away from each other, so as to adjust the width distance between the two supporting plates 9, facilitating the placement of rails with different widths and improving the versatility of the device.
