This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the utility model to the skilled person.

[0031] Example 1: a steel beam installation hoisting device, as shown in Figures 1-6 , comprising:

[0032] A hanging seat 1 for hanging on a crane hook;

[0033] Four steel wire ropes 2 connected at the bottom of the hanging seat 1;

[0034] A connecting plate 3 connected between one end of the four steel wire ropes 2;

[0035] Two moving plates 4 slidingly connected to the connecting plate 3;

[0036] A rack 5 is fixedly connected to each of the two moving plates 4;

[0037] A gear 6 is rotatably connected to the connecting plate 3, and the two racks 5 are engaged with both sides of the gear 6;

[0038] A double-rod air cylinder 7 is fixedly connected to each of the two moving plates 4;

[0039] A clamping plate 8 is fixedly connected to the extension rod of each of the two double-rod air cylinders 7;

[0040] A steel beam 0 is clamped between the four clamping plates 8;

[0041] A stabilizing assembly is provided on the moving plate 4;

[0042] A reinforcing assembly is provided on the clamping plate 8.

[0043] The stabilizing assembly comprises: rotating frames 9 rotatably connected to one side of the two moving plates 4 respectively; two buffer pads 10 rotatably connected to the two rotating frames 9 respectively; torsional springs 11 connected between the two rotating frames 9 and the two moving plates 4 respectively; two protruding rods 12 fixedly connected to the two rotating frames 9 respectively; and inclined blocks 13 fixedly connected to one side of the four clamping plates 8.

[0044] The buffer pad 10 is made of rubber material, and the buffer pad 10 made of rubber material is used for buffering pressure.

[0045] The reinforcing assembly comprises: four clamping blocks 14 slidably connected to the inner sides of the four clamping plates 8 respectively; and two compression springs 15 connected between each clamping block 14 and each clamping plate 8.

[0046] The clamping block 14 is provided with an inclined surface on one side, and the clamping block 14 provided with the inclined surface is used for reinforcement.

[0047] Initially, the torsional spring 11 is in a twisted state, and the compression spring 15 is in a compressed state. When the steel beam 0 needs to be hoisted, the staff first hangs the hanging seat 1 on the hook of the crane, then rotates the gear 6 according to the length of the steel beam 0, the gear 6 rotates to drive the two moving plates 4 to move away from each other through the two racks 5, and then the staff controls the retractable rods of the two double-rod cylinders 7 to retract. The retractable rods of the double-rod cylinders 7 retract to clamp the two sides of the steel beam 0 through the four clamping plates 8. The hook of the crane is lifted to lift the hanging seat 1, and the hanging seat 1 is lifted to hoist the steel beam 0 through the steel wire rope 2 and the connecting plate 3. Then the staff controls the position of the crane to move the steel beam 0 to the position where it needs to be installed, thereby facilitating the adjustment of the center of gravity of the steel beam 0 before hoisting, thereby ensuring the balance of the steel beam 0 during hoisting, so that the hoisting of the steel beam 0 is more stable. The retractable rods of the double-rod cylinders retract to drive the clamping plates 8 to move close, and at the same time drive the inclined blocks 13 on the two sides to move. The inclined blocks 13 move at the same time to make the protruding rods 12 rotate the rotating frames 9 downward. The rotating frames 9 rotate downward to abut against the steel beam 0 through the buffer pads 10, thereby preventing the steel beam 0 from sliding during hoisting, thereby preventing the center of gravity of the steel beam 0 from deviating, thereby enhancing the fixing effect of the steel beam 0. When the clamping plates 8 drive the clamping blocks 14 to contact the two sides of the steel beam 0, the two sides of the steel beam 0 will extrude the clamping blocks 14. The clamping blocks 14 will be lifted, the compression springs 15 will be compressed, and the two sides of the steel beam 0 will be clamped by the clamping plates 8. The clamping blocks 14 will be pressed against the steel beam 0 under the action of the compression springs 15, thereby further enhancing the stability of the steel beam 0 during hoisting, thereby further enhancing the fixing effect of the steel beam 0. After the installation of the steel beam 0 is completed, the staff controls the extension of the retractable rods of the double-rod cylinders 7, and the clamping plates 8 are out of contact with the steel beam 0. The reverse movement of the clamping plates 8 will drive the inclined blocks 13 to no longer extrude the protruding rods 12. The torsional springs 11 reset to drive the rotating frames 9 to reset, and the buffer pads 10 no longer abut against the steel beam 0. At the same time, the clamping blocks 14 are out of contact with the steel beam 0, and the compression springs 15 reset to drive the clamping blocks 14 to reset.

[0048] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
