Problems solved by technology
The existing box-type spreader design will increase the hoisting load, and at the same time, the construction period is longer, the welding volume is large, the welding is difficult, and the hoisting cost is increased
And use the method of locking the flange neck to hoist, it is easy to accidentally slip
[0003] When hoisting horizontally, the force on the sliding tail is the largest, but as the main crane lifts, the auxiliary crane sends the car, and when the equipment changes from horizontal to upright (that is, 0-45°-90°), in the state of 0-45°, the hoisting The force is from the pulling force of the whole panel to the shearing force of the lifting lug. Although the overall force of the tail is reduced, the shearing force on the lifting lug is gradually increasing until the maximum shearing force in the 45° state , so the requirements for lifting lugs are higher

Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] An equipment hoisting tail sling, the structure of which is as follows: figure 1 with figure 2 As shown, it includes an annular panel 1, lifting lug 2 and bracket 4. The inner ring of the panel 1 is connected with a triangular support 3. The diameter of the inner ring of the panel 1 is equal to the inner diameter of the flange 5, and the length of the support 3 is greater than the thickness of the panel 1. , one end extends toward the direction of the flange 5, and the other end is flush with the plane of the panel. Five sets of bolts 11 are respectively arranged on the upper and lower sides of the panel 1, and three sets of bolts 11 are respectively arranged on the left and right sides.
[0026] According to the weight of the equipment, the material material, thickness, and usage of reinforcing materials of the spreader can be adjusted. Taking the 323.8t ...

The invention discloses an equipment hoisting tail slip lifting tool and belongs to the field of equipment hoisting tools. The equipment hoisting tail slip lifting tool comprises an annular panel. A lifting lug is arranged on the upper portion of the panel. A bracket is arranged on the lower portion of the panel. One end of the bracket is elongated towards hoisted equipment. Bolts are arranged on the upper side, the lower side, the left side and the right side of the panel. The equipment hoisting tail slip lifting tool has the advantages of being low in weight, large in borne load, short in construction period, small in welding amount, easy to machine and low in cost, and meets the requirement for hoisting safety.
Description
technical field [0001] The invention belongs to the field of equipment hoisting appliances, and in particular relates to an equipment hoisting tail sling. Background technique [0002] With the standardization of safety measures required for the hoisting of large-scale equipment, when hoisting large-scale equipment, not only the foundation treatment is required to meet the requirements, the load of the main and auxiliary cranes must meet the safety regulations, and the hoisting balance beam, wire rope, snap ring, etc. must meet the safety regulations. In view of the situation that there are no lifting lugs at the bottom of some equipment, it is necessary to design a sliding tail hoisting spreader, which not only meets the hoisting requirements, but also reduces the hoisting load. The existing box-type spreader design will increase the hoisting load, and at the same time, the construction period is longer, the welding volume is large, the welding is difficult, and the hoistin...
