Typically, one left clamping plate 100 and right clamping plate 200 form a set of clamps, and at least two sets of clamps are used during the lifting process. Referring to fig. 5, for example, when welding an H-shaped member 700, a middle web is placed first, then two sets of clamps are used to hook the flange plates, and a lifting device is connected to the lifting lug 300 at the first hook 120 to lift the flange plates and weld the web in pairs.

Referring to fig. 6, the completed H-shaped member 700 has flanges on both sides, when the web in the middle of the H-shaped member 700 is in a horizontal position, i.e., the two side flanges are vertical. If the component 700 needs to be turned 90 degrees, two groups of clamps are respectively arranged on the flange plates, and four groups of clamps are arranged at the moment, and the clamps are in a vertical state, namely the first plate body 110 and the second plate body 210 are in a vertical state.

Referring to fig. 6, a lifting device is connected to the lifting lug 300 at the first body 110, the member 700 is lifted vertically, then the clamps of the side flange plate are lowered, referring to fig. 7, the member 700 is inclined, the side flange plate is kept in a state of being lifted by the opposite side clamps after contacting the ground, the side clamps are removed, then the lifting device is connected to the lifting lug 300 at the second body 210 on the opposite side clamps again, and the lifting is continued until the clamps are in a horizontal state, i.e., the first body 110 and the second body 210 are horizontal, as shown in fig. 8, at this time the member 700 is turned over 90 degrees.

Referring to fig. 3, it can be understood that the first connection part 130 includes a plurality of first through holes 131, the first through holes 131 being aligned in the length direction of the first plate body 110, and the second connection part 230 includes a plurality of second through holes 231, the second through holes 231 being aligned in the length direction of the second plate body 210, and the first through holes 131 being capable of being coaxial with the second through holes 231 and being fixed by inserting connection bolts 400.

When the first and

second plate bodies

110 and 210 are overlapped, the first and second through

holes

131 and 231 can be adjusted to be coaxial along the length direction thereof, so that the distance between the first and second hooking

portions

120 and 220 at both ends can be adjusted to accommodate the members 700 having different widths. When the first through hole 131 and the second through hole 231 are coaxial, the connecting bolt 400 is inserted and fixed, so that the first plate body 110 and the second plate body 210 are convenient to disassemble and adjust.

It is understood that the number of the first through holes 131 is at least 3, and the number of the second through holes 231 is at least 3.

When the number of the first through holes 131 and the second through holes 231 is not less than 3, the two connecting bolts 400 can be inserted on the basis that the distance between the first hooking portions 120 and the second hooking portions 220 can be adjusted, and a stable straight line can be determined at two points, so that the first plate body 110 and the second plate body 210 are connected more firmly. After the two connecting bolts 400 are inserted, at least one first through hole 131 and one second through hole 231 can be left for adjustment.

It will be appreciated that the first hooking portion 120 is provided with a pressing device 500, and the pressing device 500 can press the hooked member against the first plate body 110.

Of course, the pressing means 500 can also be provided at the second hooking portion 220. After the first hooking portion 120 and the second hooking portion 220 hook the member 700, due to different sizes of the model of the member 700, a gap exists between the surface of the edge of the member 700 and the first plate body 110 and the second plate body 210, the pressing device 500 can be adjusted, the hooked member 700 is pressed against the first plate body 110, and if the pressing device 500 is also arranged at the second hooking portion 220, the member 700 can be pressed against the second plate body 210 together, so that the clamp can firmly hook the member 700.

Referring to fig. 4, it can be understood that the pressing device 500 includes a fixing screw hole 510 and an adjusting screw 520, the fixing screw hole 510 is provided at the first hooking portion 120, the adjusting screw 520 is screw-coupled with the fixing screw hole 510 through the fixing screw hole 510, and an end of the adjusting screw 520 can be moved close to the first plate body 110.

The adjusting screw 520 is screwed into the fixing screw hole 510, and the distance between the end of the adjusting screw 520 and the first plate 110 can be adjusted by rotating the adjusting screw 520, i.e. the end of the adjusting screw 520 can be abutted against the surface of the member 700, so that the member 700 is abutted against the first plate 110.

It will be appreciated that the end of the adjustment screw 520 adjacent to the first plate body 110 is provided with a resilient pad.

The elastic pad can have floatable deformation amount with the member 700 to avoid surface damage of the member 700, and has larger friction force compared with the rigid adjusting screw 520, thereby helping to stabilize the member 700.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
