Background

With the increasing processing capacity of domestic plants, the volume of the related equipment is increasing. In the plate heat exchanger industry, the width of a stainless steel plate smaller than 1mm is gradually increased, the specification of some plates is larger than 6m multiplied by 2m (length multiplied by width), and the plates are ultra-thin and ultra-wide and have poor rigidity. The basic requirements of the manufacturing link are to enable the ultra-wide non-rigid plate to be horizontally lifted and moved, efficiently realize the processes of profiling, paired welding, assembling and the like, and ensure that the plate is not damaged. In addition, the thin plate is just like a knife edge, so that once the ultra-wide and ultra-long plate falls off, great safety threat is brought to operators, and the consequence is unimaginable.

Patent CN202046793U discloses special strut of flexible steel sheet of overlength type, including vaulting pole, upper and lower hanging (refer in particular to wire rope hoist cable), shackle, turnbuckle, steel plate pincers, five groups of single lugs and upper hanging system have been arranged on vaulting pole upper portion, five groups of double lugs and lower hanging system have been arranged to the vaulting pole lower part correspondence, and the middle wire rope of upper hanging system is connected with the turnbuckle of adjusting its length. Adopt two lug welding on the steel sheet, single lug is installed on the vaulting pole, and at the handling in-process, there is ultra-thin steel sheet and turns over the problem of perk, coming off from the lug. And the installation of two lugs can destroy the steel sheet, influences the quality of heat exchanger.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an auxiliary lifting appliance for horizontally lifting a single ultra-wide ultra-thin steel plate. The problem of the single super wide ultra-thin steel sheet turn over when the level handling warp, the landing, cause the steel sheet damaged is solved.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides an auxiliary lifting device for superwide ultra-thin steel sheet of sola, includes the girder, and girder upper surface symmetric welding has two big lugs, and girder lower surface welding has several and girder looks vertically auxiliary girder, and the auxiliary girder both ends are connected with the little lug on U type clamp top through wire rope, and the welding of little lug is on the side front end of going up that the U type pressed from both sides, and the side length degree of going up that the U type pressed from both sides is less than side length down, the height that the U type pressed from both sides and steel sheet thickness looks adaptation.

Preferably, the main beam is section steel, and the length of the main beam is slightly smaller than that of the steel plate to be hoisted.

Preferably, after the steel plate to be hoisted is hoisted, the included angle between the steel wire rope and the upper surface of the steel plate is 75-85 degrees.

Preferably, the length of the lower side of the U-shaped clamp is 1.8-2.5 times of the length of the upper side.

Preferably, the width of the secondary beam is 1/2 of the width of the steel plate to be lifted.

When the load is not loaded, the U-shaped clamp is tied on the small lifting lug by using a steel wire rope, the U-shaped clamp is in a free suspension state, and the front ends of the upper side edge and the lower side edge of the U-shaped clamp are in a tilting state.

The working principle of the utility model is as follows:

before the ultra-wide ultra-thin steel plate is horizontally lifted, an operator symmetrically clamps the U-shaped clamps on two sides of a single ultra-wide ultra-thin steel plate, then two ends of a steel wire rope are installed on the end head of the auxiliary beam and the small lifting lugs, a lifting rope of a crane is hung in the two large lifting lugs on the main beam, the crane is started, and the steel plate is horizontally lifted and transported to a specified place.

The utility model has the beneficial effects that:

(1) according to the utility model, the included angle between the steel wire rope connected between the U-shaped clamp and the auxiliary beam and the upper surface of the steel plate is strictly controlled, the auxiliary beam with reasonable length, the upper side plate and the lower side plate of the U-shaped clamp are set, and proper clamping force is given to the steel plate in the process of horizontally moving and lifting the ultra-wide ultra-thin steel plate, so that the horizontal lifting of the steel plate is safely and reliably realized, and the problems of easy deformation, extrusion and slipping in the process of horizontally moving and lifting a single ultra-wide ultra-thin steel plate are solved;

(2) in the using process of the utility model, the U-shaped clamp is clamped on the side edge of the steel plate, so that the steel plate is not damaged, and the quality of the final product is ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, an auxiliary lifting appliance for a single ultra-wide ultra-thin steel plate, including girder 1, the symmetrical welding of 1 upper surface of girder has two big lugs 2, the welding of 1 lower surface of girder has several and 1 looks vertically auxiliary girder 3 of girder, 3 both ends of auxiliary girder are connected with little lug 5 on 6 tops of U type clamp through wire rope 4, the welding of little lug 5 is on the top of the U type clamp 6 side front end, the U type clamp 6 side length of going up is less than side length down, the U type clamp 6 highly and steel plate thickness looks adaptation.

The girder 1 is shaped steel, and its length slightly is less than the length of waiting the handling steel sheet. The width of the secondary beam 3 is 1/2 of the width of the steel plate to be lifted.
