Description

A lifting device for pipeline construction

Technical Field

The utility model relates to the technical field of pipeline construction, and more specifically, to a hoisting device for pipeline construction.

Background Art

Pipeline construction refers to the process of installing, debugging and maintaining the pipeline system in an engineering project. Specifically, it involves the entire process of pipeline alignment, trenching, pipe laying, joints, soil covering, pressure testing, flushing, disinfection and site cleaning. During the pipeline construction process, especially during the installation of the pipe body, a lifting device is required to lift the pipe body and move it to the installation location for placement.

The Chinese utility model patent with publication number CN215797989U discloses a lifting device for municipal engineering sewage pipe construction. The patent enables the pipe end to be clamped by swinging two clamping plates, so as to facilitate the rapid lifting of the pipe. In addition, by setting a detection component, the clamping force of the pipe can be detected to avoid deformation caused by excessive clamping force on the pipe, and the clamping force of the pipe can be adjusted. The rotating wheel contacts the outer wall of the pipe, so that the pipe can be rotated during the installation process, so that the screw holes on two adjacent pipes can be aligned, thereby making the pipe installation faster.

However, in actual use, the rope structure unique to the above patent is used to pull the tube body, which is prone to swinging during movement, resulting in instability during movement. In addition, the length of the tube body is not fixed, and the above patent cannot be adjusted according to the length of the tube body, which makes the lifting position unstable for the tube body with a longer structure during lifting, and it is easy to fall off.

Beneficial effects of the utility model:

1. By setting the length adjustment mechanism, when in use, the gear is driven to rotate by controlling the operation of the first servo motor.

At this time, the two-way screw is driven to rotate by controlling the operation of the second servo motor, thereby driving the two movable arms to move in the opposite direction and gradually approach each other, so that the two arc-shaped clamping arms at the bottom clamp the pipe body. After stably clamping and lifting it, the piston rod of the telescopic cylinder is controlled to reset, so that the pipe body can be driven to rise and complete the lifting. After lifting and moving to the position where the pipe body needs to be installed, the pipe body is controlled to descend again, and then the rotor of the second servo motor is controlled to rotate in the opposite direction, so that the two arc-shaped clamping arms gradually separate from the pipe body, so that the pipe body can be released. The overall lifting does not adopt a rope structure, and will not swing during the movement, with high stability.

When the required length is adjusted, the first servo motor 11 can be turned off. The setting of the length adjustment mechanism is convenient for adjustment according to the length of the tube body during use, thereby increasing the scope of application and facilitating subsequent lifting.
