[0028] A fixing box 6 is fixedly provided on the other side of the mounting box 1, and a motor 7 is fixedly provided inside the fixing box 6. The output end of the motor 7 is fixedly connected to one end of a bidirectional threaded rod 5, and one end of the bidirectional threaded rod 5 is mounted on one side of the interior of the mounting groove 2;

[0029] A connecting plate 8 is fixedly provided at the bottom end of the movable plate 3, a first mounting bracket 9 is fixedly provided on the inner side of the connecting plate 8, a second threaded hole 10 is provided on the top surface of the first mounting bracket 9, a screw 11 is provided inside the second threaded hole 10, a rotating plate 12 is fixedly provided on the upper end of the screw 11, and a first pressing plate 13 is fixedly provided on the lower end of the screw 11;

[0030] The mounting box 1 is fixedly provided with mounting plates 16 on the front and rear sides, and an electric push rod 17 is fixedly provided on the upper end surface of the mounting plate 16. The output end of the electric push rod 17 is fixedly provided with a second mounting bracket 18, and the lower ends of the front and rear sides of the second mounting bracket 18 are fixedly provided with a second pressing plate 19. The utility model is provided with a motor, a bidirectional threaded rod, a movable plate, a connecting plate, and a first mounting bracket, and the motor is started. The motor can drive the bidirectional threaded rod to rotate, and the movable plates on both sides can drive the connecting plate and the first mounting bracket to move inward, so that the width of the first mounting bracket on both sides can be adjusted to a width that matches the steel structure.

[0031] Specifically, two movable plates 3 are provided, and the two movable plates 3 are respectively sleeved on the outer sides of the left and right threads of the bidirectional threaded rod 5 through the first threaded holes 4. The two movable plates 3 are respectively sleeved on the outer sides of the left and right threads of the bidirectional threaded rod 5 through the first threaded holes 4. The bidirectional threaded rod 5 and the movable plates 3 are threadedly connected. The advantage is that when the bidirectional threaded rod 5 rotates, the movable plates 3 on both sides are affected by the threads of the bidirectional threaded rod 5 and can move inward simultaneously.

[0032] Specifically, the screw 11 is disposed inside the second threaded hole 10 , and the screw 11 and the second threaded hole 10 are threadedly connected. When the screw 11 rotates, the screw 11 is acted upon by the threads of the second threaded hole 10 and is thus able to move downward.

[0033] Specifically, a first rubber pad 14 is fixedly provided on the lower end surface of the first pressing plate 13 .

[0034] Specifically, a second rubber pad 15 is fixedly installed at the bottom of the first mounting frame 9. The second rubber pad 15 can increase the friction force on the lower end of the steel structure, and the first rubber pad 14 can increase the friction force on the upper end of the steel structure, thereby improving the clamping effect on the steel structure. The utility model is provided with a rotating plate, a screw, and a first pressing plate. The rotating plate is rotated to drive the screw and the first pressing plate to move downward, and the first pressing plate can thereby press and fix the steel structure.

[0035] Specifically, the second mounting bracket 18 is located at the lower end of the mounting box 1. When the second mounting bracket 18 moves downward, the second pressing plate 19 can cooperate with the clamping component inside the first mounting bracket 9 to fix the steel structure. The utility model provides an electric push rod, a second mounting bracket, and a second pressing plate. When the electric push rod is started, the output end of the electric push rod can drive the second mounting bracket and the second pressing plate to move downward. The second pressing plate can thus press and fix the two ends of the steel structure, thereby improving the stability of the steel structure.

[0036] Specifically, a connecting frame 20 is fixedly provided on the upper end surface of the installation box 1 , and a hanging ring 21 is fixedly provided on the upper end surface of the connecting frame 20 .

[0037] Specifically, a lifting rope 22 is provided inside the lifting ring 21 . The advantage is that the provision of the connecting frame 20 facilitates the installation of the lifting ring 21 , and the provision of the lifting ring 21 facilitates the sleeve connection of the lifting rope 22 .

[0038] Specifically, the lifting rope 22 is made of a nylon rope or a steel wire rope. The nylon rope has the characteristics of being light, fast, wear-resistant and collision-resistant, and will not generate sparks when colliding, thereby ensuring the safety of lifting.

[0039] When in use, the personnel first lifts the installation box 1 to the designated position through the crane and the lifting rope 22, and then starts the motor 7. The output end of the motor 7 can drive the bidirectional threaded rod 5 to rotate, and the movable plates 3 on both sides are affected by the threads of the bidirectional threaded rod 5 so that they can move inward at the same time, and the movable plate 3 can drive the connecting plate 8 and the first mounting bracket 9 to move inward. After adjusting the first mounting brackets 9 on both sides to a width matching the steel structure, the personnel rotates the rotating plate 12, and the rotating plate 12 drives the screw 11 to rotate. The screw 11 is affected by the threads of the second threaded hole 10 and can drive the first pressing plate 13 and the first rubber pad 14 to move downward. The first pressing plate 13 and the first rubber pad 14 can cooperate with the second rubber pad 15 to clamp and fix the steel structure. Then the personnel starts the electric push rod 17, and the output end of the electric push rod 17 can drive the second mounting bracket 18 and the second pressing plate 19 to move downward. The second pressing plate 19 can press and fix the two ends of the steel structure, thereby improving the stability of the steel structure hoisting.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
