Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0038] Such as Figure 1 to Figure 11 As shown, the turning mechanism in the method for reducing the tail height of the equipment includes 7 including a saddle 1, a roller 2, a support 3 and an adjustment steel plate 4. in:
[0039] Saddle 1 is the part that is in direct contact with the housing of equipment 5 to be turned over, such as Figure 1 to Figure 5 As shown, the saddle 1 is a box structure, and is composed of a saddle arc-shaped plate 11, two saddle side plates 12, a saddle bottom plate 13 and two saddle boards adapted to the curvature of the housing of the equipment 5 to be turned over. The seat end plate 14 is welded; in order to improve the structural strength of the overturned saddle, a plurality of reinforcing plates 15 parallel to the end plate 14 are evenly welded at intervals in the casing. Two saddle lifting lugs 16 are r...

The invention relates to a method for reducing the tail height of equipment, which is characterized by comprising the following steps: (1) ensuring the upper end of a turnover mechanism to lean against the shell of equipment to be turned over and installing the turnover mechanism on the equipment to be turned over; (2) installing a lifting hook and a rigging on the equipment to be turned over, lifting the lifting hook and the rigging and ensuring the equipment to be turned over to rotate around the turnover mechanism, wherein the tail height of the equipment to be turned over is gradually reduced at the moment until the height meets the requirement of the lifting height; and (3) installing lifting equipment at the tail of the equipment, after that, continuing lifting the lifting hook and the rigging, ensuring the equipment to be turned over to rotate around the lifting equipment and equipment to be lifted gradually breaking away from the turnover mechanism; and when the shell of the equipment to be lifted leaves the peak of the turnover mechanism, separating the turnover mechanism from the equipment to be turned over, wherein the turnover mechanism comprises a saddle, a drum and asupport. The turnover mechanism and the turnover method of the invention are high in safety performance, simple in operation and low in lifting cost.
Description
technical field [0001] The invention relates to the field of auxiliary equipment for hoisting and hoisting of large-scale equipment, and specifically refers to a method for reducing the height of the tail of the equipment when hoisting by a crane without a tail. Background technique [0002] In the hoisting of equipment, there are many hoisting techniques that do not use the tail of the crane. When using these hoisting techniques, it is necessary to install a roller or other tail-sliding device at the end of the equipment. These devices are usually mounted on hinged bearings or other structural forms of rotating shaft systems and / or anti-roll systems. The height of the tail of the equipment directly affects the height of the shaft system and the anti-roll system. The lower the shaft system and anti-tilt facilities are, the easier it is to install these facilities, and the safer the hoisting process is. However, due to the limitation of the dump height of the transport veh...
