Description

Technical Field

[0001] The utility model relates to the field of foundation pit engineering equipment, in particular to a quick-detachable inclined lifting device for foundation pit engineering support pipes. Background Art

[0002] The foundation pit engineering support pipe is a steel pipe used for the foundation pit support structure. It is connected by welding or bolts to form a stable support structure. The function of the foundation pit engineering support pipe is to withstand soil pressure and ground load, and maintain the stability and safety of the foundation pit. When installing the foundation pit engineering support pipe, a quick-detachable inclined lifting device is required.

[0003] In the existing quick-detachable inclined lifting device, it generally includes an inclined lifting body, a connecting piece and a fixing piece. The inclined lifting body is generally a crane, and the inclined lifting body is connected to the fixing piece through a connecting piece. The fixed connection is generally provided with two fixing plates, and the foundation pit engineering support pipe is placed between the two fixing plates. The two fixing plates are also provided with threaded rods and fixing plates for further fixing the foundation pit engineering support pipe during installation. However, in the existing installation of the foundation pit engineering support pipe, the foundation pit engineering support pipe is sent from between the two fixing plates into the interior of the two fixing plates, and the overall installation process is relatively quick. The placement of the foundation pit engineering support pipe can be achieved by simply loosening the fixing plate, thereby achieving a quick-detachment effect. However, since the distance between the two fixing plates is set to be fixed, when the diameter of the foundation pit engineering support pipe is large, it may be difficult for the two fixing plates to fix the foundation pit engineering support pipe.

[0004] Therefore, it is necessary to provide a new quick-detachable inclined hanging device for foundation pit engineering support pipe to solve the above technical problems. Utility Model Content

[0016] 1. The device is provided with a first threaded rod and two fixed plates. The distance between the two fixed plates can be adjusted by rotating the first threaded rod, so that the entire device can adapt to foundation pit engineering support pipes of different diameters.

The two connecting plates 11 are movably arranged in a mounting groove provided at the bottom of the fixing frame 3.

The end of the first threaded rod 10 close to the two connecting plates 11 is movably connected to the inner side wall of the mounting groove. One end of the first threaded rod 10 is fixedly connected to the rotating disk 6.

[0028] The limiting group includes a second threaded rod 9, a mounting frame 5, a friction block 7 and a limiting rod 12, one side of the mounting frame 5 is fixedly connected to one side of the fixing plate 4, one end of the second threaded rod 9 movably passes through the mounting frame 5 and the fixing plate 4, and one end of the second threaded rod 9 close to the fixing plate 4 is movably connected to one side of the friction block 7, a plurality of grooves are provided on the friction block 7, and two limiting rods 12 are provided with one end. One end of each limiting rod 12 is fixedly connected to one side of the friction block 7, and the ends of the two limiting rods 12 away from the friction block 7 movably pass through the fixing plate 4. The ends of the two limiting rods 12 close to the fixing plate 4 are fixedly connected to the limiting plate 13, and the cross-sectional sizes of the two limiting plates 13 are larger than the cross-sectional sizes of the two limiting rods 12. One end of the second threaded rod 9 is fixedly connected to a movable disk 14;

[0029] A connecting piece 2 is provided between the upper end of the inclined hanging body 1 and the fixed frame 3, and the opposite ends of the connecting piece 2 are fixedly connected to the upper end of the inclined hanging body 1 and the fixed frame 3 respectively;
