Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in the figures 1 to 3, the utility model comprises a U-shaped plate 1 which is provided with a downward opening and can be buckled on an I-shaped steel structure, a hanging ring 2 is arranged above the U-shaped plate 1 at intervals, a through groove 3 is arranged at the middle position of the left side plate and the right side plate of the U-shaped plate 1, a clamping unit is respectively arranged at the left side and the right side of the U-shaped plate 1, the centre gripping unit includes two mutual articulated connecting rods 4, two connecting rods 4 articulate into an opening V type structure outwards, be equipped with pressure spring 5 between two connecting rods 4, the free end of two connecting rods 4 articulates respectively have one can with the I-shaped steel construction about the backup pad 6 of two internal planes contact, the articulated position of two connecting rods 4 is fixed with two wire rope 7, be equipped with two first fixed pulley 8 about logical groove 3 symmetrical arrangement on two curb plates about U-shaped plate 1 respectively, two wire rope 7 free ends of homonymy run through corresponding 1 curb plate of side U-shaped plate and bypass corresponding 8 after-fixing on rings 2 of first fixed pulley 8.

In order to realize rings 2's installation, U-shaped rod 9 that two front and back side by side interval arrangements are equipped with in the upper end of U-shaped plate 1, and the open end of two U-shaped rod 9 is fixed on U-shaped plate 1's up end, installs one in two U-shaped rod 9 and can reciprocate and both ends stretch out respectively to the bracing piece 10 that corresponds the side U-shaped rod 9 outside, and two of homonymy are fixed respectively at the both ends of bracing piece 10 with wire rope 7, and rings 2 fix the intermediate position at bracing piece 10 through the montant.

In order to reduce the abrasion of the steel wire ropes 7, four second fixed pulleys 11 which correspond to the four steel wire ropes 7 one by one are fixed at the bending positions of the U-shaped plate 1.

The utility model discloses a concrete working process is: the V-shaped structures on two sides of the device in an initial state are arranged on the outer side of the U-shaped plate 1, the U-shaped plate 1 is buckled at the upper end of an I-shaped steel structure when the device is used, the two V-shaped structures are respectively arranged on two sides of the I-shaped steel structure through the through grooves 3, the pointed end of the V-shaped structure faces to a rib plate of the I-shaped steel structure when the device is placed in the device, two connecting rods 4 on the V-shaped structure are extruded, a pressure spring 5 is compressed, the opening of the V-shaped structure is reduced, when the V-shaped structure is placed in the I-shaped steel structure, the V-shaped structure is loosened, a supporting plate 6 is enabled to extrude the inner side wall of the I-shaped steel structure under the reset action of the pressure spring 5 pair, an anti-skid pad can be arranged on the contact end surface of the supporting plate 6 and the I-shaped steel structure, after, the V-shaped structure has a tendency of opening in the process of tightening the steel wire rope 7, and the support plate 6 extrudes the I-shaped steel structure due to the tendency, so that the steel structure is firmer in the hoisting process.

After the hoisting is finished, the hoisting ring 2 is loosened, the V-shaped structure can be taken out from the I-shaped steel structure after the steel wire rope 7 is loosened, and the whole process is convenient and fast.

The significant benefits of the present device: this device is when hoist and mount steel construction, tighten up through the rope and realize that rope pulling V type structure opens, this form is opened produced pressure and steel construction gravity directly proportional, wire rope 7 does not produce direct contact with the steel construction at whole hoist and mount in-process simultaneously, can effectual reduction wire rope 7's wearing and tearing, support clamping means through driving V type structure is to contrast traditional clamping device, the workman only needs to move V type structure back and forth movement can realize the fixed of steel construction, the weight of V type structure will be far less than traditional centre gripping worker weight, make things convenient for workman's operation more.
