Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art.

[0021] Such as figure 1 , 2 As shown, the cement pipe is laid flat, the horizontal beam (1) is hoisted above the pipe joint, the two vertical arms (2) naturally hang down on both sides of the pipe joint, and the round pin (4) is inserted into the pipe joint hoisting hole through the pin sleeve (5) The pipe joint is lifted inside, and the wing-shaped baffle (8) restricts the pipe joint from turning over and keeps the pipe joint stable. Such as Figure 5 As shown, the pin sleeve (5) is installed in the ball seat and can be rotated universally to facilitate the insertion and extraction of the round pin. Before lifting, insert the safety pin (7) to prevent the round pin from loosening and withdrawing, so as to ensure safe lifting.

[0022] Such as image 3 As shown, when the pipe joi...

Abstract

The invention relates to the technical field of engineering lifting operations and specifically relates to a lifting device for a large cement pipe and a construction method thereof. The lifting device for the large cement pipe comprises a transverse hanging beam, two plumbing arms, a rotary shaft, a pair of round plug pins, round pin sleeves, a ball seat, a safety pin and a wing-shaped blocking plate. The device for the large cement pipe is characterized in that a lifting hook hole is arranged in the middle of the transverse hanging beam, hanging ring holes are arranged at two ends of the transverse hanging beam, the hanging ring holes are used for suspending the two plumbing arms respectively through the rotary shaft, the round pin sleeves are embedded on the lower portions of the two plumbing arms respectively, and the pair of round plug pins is inserted into lifting holes which are embedded on the outer wall of the cement pipe through round pin sleeve inner holes. By means of the lifting device for the large cement pipe and the construction method thereof, the problems and hidden dangers that the large cement pipe lifting in prior art is difficult to overturn, low in efficiency and large in risk are solved. According to the lifting device for the large cement pipe and the construction method thereof, a stable lifting can be achieved during a construction process, the large cement pipe can be overturned, the application is wide, the device can be used for lifting, loading, unloading and overturning of the large cement pipe, construction safety is simultaneously guaranteed on the basis of a guarantee for construction efficiency, besides, stable and smooth operation can be maintained during processes of lifting, shifting, inserting and drawing, and the lifting device for the large cement pipe and the construction method thereof are safe, reliable, convenient and rapid.

Description

[technical field] [0001] The invention relates to the technical field of engineering hoisting operations, in particular to a hoisting tool for large cement pipes and a construction method thereof. [Background technique] [0002] In the hoisting operation of cement pipes, two round holes are usually pre-buried on the outer wall of the large cement pipes for hoisting. On the ear, the hook is hung in the middle of the wire rope to lift the pipe joint. In the prior art, the structure and principle of this kind of sling is simple, but there is a risk of the lifting lug slipping from the lifting hole, which poses a relatively large safety hazard. Secondly, cement pipes need to be turned over frequently during production, storage, transportation and installation, and the pipe joints are likely to interfere with the steel wire rope when they are turned over, which brings certain difficulties to the operation. In addition, during the operation process, when the center of gravity of...
