Embodiment Construction
[0027] The present invention proposes a device for binding and hoisting large-tonnage railway single-line simply supported trough beams across the railway. Please refer to Figure 1 to Figure 5 As shown, the device includes a limit mechanism 1, a corner protection mechanism 2, a suspension beam mechanism 3 and a sling 4,
[0028] Wherein the limit mechanism 1 includes a limit structure one and a limit mechanism two, the limit structure one and the limit mechanism two are symmetrically arranged on both sides of the channel beam along the length direction of the channel beam, the limit structure one and the limit structure The second positioning mechanism is composed of a limiting steel bar I101 and a limiting steel bar II102. The limiting steel bar I101 is fixed on the upper part of the outer side of the channel beam channel arm, and a limiting hole is opened on the limiting steel bar I101; the limiting steel bar II102 It is fixed at the lower part of the outer side of the chan...

The invention provides a device for cross-railway bundled hoisting of a large-tonnage railway single-line simple supporting channel girder, and belongs to the technical field of hoisting devices. The device comprises a limiting mechanism, a corner protection mechanism, a hoisting beam mechanism and a sling. The hoisting beam mechanism, the limiting mechanism and the corner protection mechanism cooperate with the sling to wrap the channel girder, and the two ends of the sling are connected with hoisting hooks. Compared with the prior art, the device for hoisting is simple and practicable, and during hoisting operation, damage of a channel girder body and steel wire rope movement are avoided; and meanwhile the number of times of use of the device for hoisting is increased, and construction experience is provided for large-tonnage concrete member hoisting. The device is high in work efficiency, long in service life and suitable for being widely used and popularized.
Description
technical field [0001] The invention belongs to the technical field of hoisting devices, and is particularly suitable for a bundled hoisting device for a large-tonnage railway single-line simply-supported channel beam spanning the railway. Background technique [0002] The hoisting device is an important part of the hoisting process. According to different hoisting methods, it can be divided into single-vehicle hoisting, double-machine hoisting, crane hoisting and hydraulic lifting. How to protect the integrity of objects during hoisting is an urgent problem to be solved. [0003] Single-vehicle hoisting of large-scale equipment is heavy, so if a single crane is used for hoisting, most of them will use a crawler crane with a rated lifting capacity of more than 50 tons. Because the chassis is relatively stable, the crawler crane has a large lifting capacity. The objects to be hoisted are generally steel structure objects, and no special protection design is required to set ...
