[0024] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] The present invention provides a lifting device for facilitating the lifting of prefabricated square integrated pipe sections through improvement. The technical solution of the present invention is:

[0026] like Figures 1 to 5 As shown, an embodiment of the present invention provides a sling for convenient lifting of prefabricated square integrated pipe sections, including a U-shaped sling 1, a lifting part 2 is fixedly installed on the upper part of the U-shaped sling 1, a slide groove 3 and a lifting hole 4 are opened on the lifting part 2, a lifting ring 5 is slidably installed on the lifting part 2, and the lifting ring 5 slides with the slide groove 3 and the lifting hole 4. A pair of balancing arms 8 are fixedly installed on the inner bottom of the U-shaped sling 1, and a rubber pad 9 is fixedly installed on each balancing arm 8. It also includes a clamping assembly. The U-shaped sling 1 can be easily lifted in conjunction with the lifting device to lift the directional integrated pipe. The multiple lifting holes 4 can be adjusted according to the weight and size of different square integrated pipes, thereby greatly improving the stability during the lifting process.

[0027] The clamping assembly is arranged on the U-shaped spreader 1 .

[0028] The clamping assembly includes a mounting groove 7 opened at the top of the U-shaped sling 1, and a fixing plate 11 is fixedly installed inside the mounting groove 7. A pair of adjusting screws 12 are threadedly connected to the fixing plate 11. The setting of the clamping assembly can improve the stability of the clamping and fixing of the square integrated pipe, thereby ensuring further improvement of the stability during the lifting process.

[0029] Furthermore, a clamping plate 14 is rotatably installed at the bottom of each adjusting screw 12, and a rubber pad 15 is fixedly installed at the bottom of the clamping plate 14. The clamping plate 14 can be set to clamp the square integrated pipe, and the stability of the clamping of the square integrated pipe can also be ensured.

[0030] Furthermore, a rotating ring 13 is fixedly installed at the end of each adjusting screw 12, and a pair of X-shaped connecting rods 16 are fixedly connected between the clamping plate 14 and the fixed plate 11 through a movable shaft. The rotating ring 13 can easily control the rotation of the adjusting screw 12, thereby facilitating the control of the downward movement of the clamping plate 14 and the rubber pad 15, and then facilitating adjustment according to the thickness of different square integrated pipes, thereby improving the practicality of the clamping assembly.

[0031] Furthermore, a reinforcing rod 6 is fixedly installed inside the U-shaped sling 1, and a pair of reinforcing plates 10 are fixedly installed between the two ends of the balance arm 8 and the U-shaped sling 1. The provided reinforcing rod 6 and reinforcing plate 10 can greatly improve the structural strength of the device, thereby greatly improving the safety during the lifting process.

[0032] The specific working principle is: install the U-shaped sling 1 on the square integrated pipe, rotate the adjusting screw 12 through the rotating ring 13, and thus move the clamping plate 14 and the rubber pad 2 15 downward, and then cooperate with the balance arm 8 to clamp the square integrated pipe. The setting of rubber pad 1 9 and rubber pad 2 15 can improve the stability of clamping the square integrated pipe. After it is fixed, the lifting effect of the square integrated pipe can be achieved by using the lifting ring 5 through the lifting part 2 and the opened lifting hole 4. In addition, the appropriate lifting hole 4 is selected for lifting according to the size and weight of different square integrated pipes, thereby improving the safety of the device during lifting.

[0033] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
