Problems solved by technology

[0003] In the construction industry, the existing segmental beam hoist is usually equipped with a single bracket to lift the segmental beam. Although it is simple to use, the segmental beam is prone to unbalanced force during the hoisting process of the segmental beam. phenomenon, resulting in a large swing of the segmental beam during the lifting process
In addition, for some huge segmental beams, the spreaders in the prior art obviously cannot meet the needs of use

Embodiment 1

[0026] see figure 1 , In Embodiment 1 of the present invention, a segment beam hanger includes: a cross frame 3, a first bracket 7 and a second bracket 11; the upper end of the first bracket 7 and the upper end of the second bracket 11 are welded and fixed with The first fixing block 2 is integrally formed with the second bracket 11 , and the first fixing block 2 and the first bracket 7 are integrally formed; the upper end of the second bracket 11 is connected with the horizontal frame 3 through the first fixing block 2 Fixed, the upper end of the first bracket 7 is connected and fixed with the horizontal frame 3 through the first fixing block 2;

[0027] A second fixing block 5 is arranged in the middle of the horizontal frame 3, a pull ring 1 is arranged on the upper end of the second fixing block 5, and a first hook 6 is arranged at the lower end of the second fixing block 5; Blocks 10 are provided on the left and right sides of the two brackets 11 , and the first bracket ...

Embodiment 2

[0034] see image 3 , further, a limit assembly is provided inside the opening channel 14 of the stretching assembly 9, and the limit assembly includes a pull handle 18, a connecting rod 19 and an insertion end 20, and the upper end of the connecting rod 19 passes through the slider 13. The end part is provided with a pull handle 18, the lower end of the connecting rod 19 passes through the slider 13 and then extends into the open channel 14, and the bottom end of the connecting rod 19 is provided with an insertion end 20;

[0035] Specifically, a compression spring 21 is installed on the portion of the connecting rod 19 between the insertion end 20 and the inner wall of the slider 13;

[0036] When the stretching assembly 9 slides on the first bracket 7 or the second bracket 11 and needs to be limited by the limiting assembly, after the stretching assembly 9 slides on the first bracket 7 or the second bracket 11 to an appropriate position, The insertion end 20 automatically ...

Abstract

The invention relates to the technical field of segmented girder lifting devices, in particular to a segmented girder lifting device. The segmented girder lifting device comprises a transverse frame,a first support and a second support; a second fixing block is arranged in the middle of the transverse frame, a pull ring is arranged at the upper end of the second fixing block, and a first hook isarranged at the lower end of the second fixing block; first fixing blocks are fixedly welded to the upper end of the first support and the upper end of the second support respectively; and stretchingassemblies are arranged on the first support and on the second support respectively. The segmented girder lifting device is reasonable in structural design; when a segment girder needs to be hoisted,the device is wound on the segmented girder through ropes, then the ropes are stretched by the stretching assemblies on the first and second supports and the first hook at the lower end of the secondfixing block, finally the transverse frame is stretched through a hoisting machine, and then the segmented girder is lifted; and due to the fact that multiple stretching points are arranged on the ropes, the stress balance of the segmented girder in the hoisting process and the stability during ascending are improved.

Description

technical field [0001] The invention relates to the technical field of a segment beam spreader, in particular to a segment beam spreader. Background technique [0002] A spreader is a device that lifts heavy objects in a hoisting machine. The most commonly used slings for lifting finished items are slings, slings, and others include slings, lifting suction cups, clamps and forks. Spreaders are widely used in the lifting and hoisting industry, especially in the construction of high-rise buildings. [0003] In the construction industry, the existing segment beam spreaders are usually equipped with a single bracket to hoist the segment beams. Although the use is simple, the segment beams are prone to unbalanced forces during the segment beam hoisting process. phenomenon, resulting in a large swing of the segment beam during the lifting process. In addition, for some bulky segment beams, the spreader in the prior art obviously cannot meet the usage requirements. [0004] In ...
