Description

Technical Field

[0001] The utility model relates to the field of H-shaped steel beam hoisting, in particular to an H-shaped steel beam hoisting device. Background Art

[0002] A common H-beam lifting device is a lifting clamp. A lifting clamp is a device used to lift and suspend heavy objects. As a common lifting device, the lifting clamp is widely used in construction, engineering, manufacturing and other fields for lifting and suspending heavy objects, including H-beams. It has the advantages of strong load-bearing capacity, flexible operation, safety and reliability, and can meet various lifting needs.

[0003] By comparing with the H-beam lifting device of patent announcement number CN215886044U, in this scheme, when this device lifts and clamps the H-beam, it is necessary to drag the two ends of the H-beam to insert it between the clamping devices. When lifting and clamping the H-beam with a longer length, it may be necessary to lift the H-beam and insert it between the clamping devices through a large amount of labor. This process consumes a lot of labor. At the same time, the H-beam is clamped and fixed in multiple directions by twisting multiple bolts, which increases the clamping time. It is inconvenient to use and is not conducive to lifting longer H-beams. There are certain limitations. Utility Model Content

The rotating frames 34 are rotatably installed on both sides of the adjustment frame 31, and the two rotating frames 34 are symmetrically arranged on both sides. The second gear 33 is fixedly installed on the rotating frame 34 on one side, and the first gear 32 is fixedly installed on the rotating frame 34 on the other side, and the first gear 32 is meshed with the second gear 33. The kinetic energy of the servo motor 35 drives the rotating frame 34 on one side to rotate, and then the first gear 32 on the rotating frames 34 on both sides is meshed with the second gear 33, thereby driving the rotating frames 34 on both sides to rotate in the opposite direction at the same time, and then the rotating frames 34 on both sides drive the limit frames 210 on both sides to realize the state of opening outward to be clamped, and then the limit frames 210 after opening on both sides are placed on both sides of the steel body 1, which facilitates the effect of clamping and fixing the steel body 1, saves manpower and material resources, and improves the convenience of using the device;

[0031] In this embodiment: the clamping mechanism 2 includes a sliding seat 21, a slider 22, a moving block 23, a top block 24, a clamping block 25, a slide rail 26, a fixed seat 27, a hanging frame 28, a hanging rope 29, and a limit frame 210. The limit frames 210 are arranged on both sides of the steel body 1. Two slide rails 26 are arranged on the inner wall of the limit frame 210, and the two slide rails 26 are arranged symmetrically up and down. The slide rails 26 are slidably installed with sliders 22, and the sliders 22 and the slide rails 26 are connected by springs. Clamping blocks 25 are arranged between the upper and lower slide rails 26, and the clamping blocks 25 are fixedly connected to the limit frames 210. The clamping blocks The upper and lower sides of the 25 are provided with moving blocks 23, and the moving blocks 23 and the clamping blocks 25 are both arc-shaped on the side close to each other.

The top blocks 24 are slidably connected to the limit frame 210. The clamping blocks 25 and the top blocks 24 are both provided with anti-skid pads on the side close to the steel body 1 to increase the friction between the steel body 1 and are more conducive to clamping and fixing. Sliding pads are fixedly installed on the top of the limit frame 210.

The upper end of the sliding seat 21 is fixedly installed with a fixed seat 27, and a hanging frame 28 is arranged above the fixed seat 27. The hanging frame 28 and the fixed seat 27 are connected by a hanging rope 29. The hanging frame 28 is lifted and pulled upward by the hook, and the fixed seats 27 on both sides are driven to be pulled upward by the hanging ropes 29 on both sides.

The lifting rope 29 drives the fixing seats 27 on both sides to pull upwards, and at the same time, the limit frames 210 under the fixing seats 27 on both sides will move toward the direction of the steel body 1 due to their own gravity, thereby driving the clamping blocks 25 on both sides of the clamping assembly to move toward the direction of the steel body 1, and during the movement, the upper and lower moving blocks 23 are pushed to move away from each other, driving the upper and lower top blocks 24 to move away from each other, so that the upper and lower sides of the steel body 1 are supported and fixed, and then the clamping blocks 25 on both sides clamp and fix the two sides of the steel body 1. When the steel body 1 itself has a heavier gravity, the clamping force of the clamping blocks 25 and the top blocks 24 on both sides on the steel body 1 is greater, and the clamping effect of the steel body 1 adaptively applied by the clamping assembly is improved, thereby improving the effect of stable clamping and fixing of the steel body 1, reducing the shaking and displacement of the steel body 1 during hoisting, and improving the safety of the steel body 1 during hoisting.
