Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric power engineering construction equipment, in particular to an electric power engineering pipeline installation device and a use method thereof. BACKGROUND

[0002] In electric power engineering construction, pipeline installation is a key link, involving the laying and butt joint of various types of pipelines such as cable protection pipes, oil pipelines and water pipes. The traditional pipeline installation relies on manual operation combined with simple lifting equipment. The construction personnel need to first transport the pipeline to the installation position by manual carrying or small forklift, and then adjust the height, angle and horizontal position of the pipeline by means of crowbar, hand-operated hoist and other tools, and finally fix and connect. This way not only requires high physical strength of the construction personnel, but also is difficult to ensure accuracy in pipeline positioning, which is prone to butt joint deviation and affects the engineering quality.

[0003] With the expansion of electric power engineering scale and the improvement of construction standards, the limitations of the traditional installation method become more and more obvious. On the one hand, large-scale electric power pipelines are often heavy and long, and manual carrying and adjustment not only have low efficiency, but also have safety hazards such as falling from a high place and pipeline sliding, especially when installing overhead pipelines or working in narrow spaces, the safety risk increases significantly. On the other hand, the precision of manual operation is limited, and the angle deviation and height error during pipeline butt joint may lead to a decrease in sealing performance, and later problems such as leakage and corrosion may occur, increasing maintenance costs. In addition, the traditional equipment has single function, usually only one of lifting or moving, and needs to be used with multiple devices, which not only increases equipment investment, but also reduces construction continuity.

[0004] Although some pipeline installation auxiliary devices have appeared in the prior art, most of them have problems such as complex structure, cumbersome operation or insufficient adaptability. For example, some devices can only realize single-direction position adjustment and cannot meet the multi-dimensional adjustment requirements of pipeline installation. Some devices rely on external power supply and cannot be used in field or construction sites without fixed power supply facilities. Some devices have insufficient stability design and are prone to shaking when lifting heavy objects, affecting operation safety and precision. Therefore, it is necessary to develop an electric power engineering pipeline installation device that integrates the functions of moving, lifting and multi-direction adjustment, and is easy to operate and has high stability, which is the key to solving the current construction problems. SUMMARY

[0005] The purpose of the present application is to provide an electric power engineering pipeline installation device and a use method thereof, which can effectively solve the problems in the background art.

[0006] The technical solution adopted by this invention to solve its technical problem is: a power engineering pipeline installation device, the structure of which includes a walking component, a lifting component, and a rotating clamping component.

A cavity for fixing the pipe is formed between the upper fixing clamp and the lower fixing clamp.

[0009] Furthermore, the linkage component includes trapezoidal blocks located at both ends of the top of the chassis.

[0013] Furthermore, a second motor is provided at the bottom of the lifting plate, and the top output end of the second motor is connected to the bottom of the turntable.

[0036] The linkage assembly includes trapezoidal blocks 28 located at both ends of the top of the chassis 3. The top of each trapezoidal block 28 has a gradually rising inclined surface.

The turntable 16 is rotatably mounted on the top of the lifting plate 14 via bearings. Driven by the second motor 15, the turntable 16 can rotate 360 ​​degrees.

[0040] The working process of this embodiment is as follows:

[0041] The operator uses steering control module 5 to control the equipment to move to the pipeline installation position;

[0042] Place the pipe 25 to be installed between the upper fixed clamp 23 and the lower fixed clamp 24, and start the electric actuator 26 to raise the lower fixed clamp 24 to clamp and fix the pipe 25.

[0043] The first motor 7 is started to drive the lead screw 8 to rotate, which drives the connecting seat 9 and the horizontal slide bar 10 to move. The lifting plate 14 is raised and lowered through the scissor bar 13, and the pipe 25 is adjusted to a suitable height. At the same time, the horizontal slide bar 10 pushes the trapezoidal block 28 down, so that the anti-slip block 30 contacts the ground to enhance stability.

[0044] According to the installation requirements, the horizontal rotation angle of the pipe 25 is adjusted by the second motor 15, the horizontal position of the pipe 25 is adjusted by the hydraulic cylinder 17, and the circumferential angle of the pipe 25 is adjusted by the rotary motor 21.

[0045] After pipe 25 is adjusted into place, the installation work will proceed.

[0046] After installation, reset all components, loosen pipe 25, and move the equipment to the next work point.
