[0029] By Figures 1-4It can be known that the utility model discloses a kind of tow device for pipeline transportation in narrow space, including mobile unit 1 and the traction unit 2 for the power of mobile unit 1, the mobile unit 1 is the main part of directly bearing and transporting pipeline, it is designed as small vehicle form, to adapt to the complex terrain and limiting condition in narrow space, the traction unit 2 is located in coke oven basement, is fixedly installed by solid support or frame, it is connected with mobile unit 1 by steel wire rope, ensure that traction force can be stably, efficiently transmitted to mobile unit 1, the traction unit 2 is wound or released by rotating drive steel wire rope, and then produce traction or braking effect, the steel wire rope passes through pulley component, pulley component not only can change the direction of force, also can reduce the required tension by increasing the number of pulley, improve traction efficiency.

[0030] By Figures 2-4 It can be known that the mobile unit 1 includes trolley main frame 11, universal wheel 12 symmetrically arranged under the trolley main frame 11, pipe support part 13, bolt 14 for connecting pipe support part 13 and trolley main frame 11 and bolt hole 15 opened on the trolley main frame 11.

[0031] By Figure 2 It can be known that the trolley main frame 11 is welded by two channel steels with a length of 1500mm, and the two channel steels are welded in an opposite manner to form a stable mouth-shaped structure.

[0032] By Figures 2-3 It can be known that the trolley main frame 11 includes traction lug 111, which is welded and fixed to the center of the front end of the trolley main frame 11, and is the key hub connecting the mobile unit 1 and the traction unit 2, which is tightly connected with the steel wire rope of the traction unit 2 by using a snap ring, to ensure the stability and safety during the whole carrying process.

[0033] Optionally, the traction lug is made of 14mm steel plate.

[0034] A plurality of universal wheels 12 are arranged in pairs below the trolley main frame, in this embodiment, the universal wheels are 4 groups, which are equidistantly distributed below the trolley main frame, to provide omnidirectional movement capability.

[0035] By Figure 3 It can be known that the pipe support part 13 includes first pipe support 131 connected with trolley main frame 11 through bolt 14 and second pipe support 132 welded with trolley main frame 11.

[0036] Specifically, the first pipe support 131 is connected and detached quickly with the bolt hole 15 on the trolley body frame 11 through the bolt 14, and these bolt holes are arranged equidistantly on the trolley body frame, so that the operating personnel can adjust the distance between the two pipe supports according to the actual needs, thereby easily adapting to various different specifications of pipes.

[0037] The second pipe support 132 is spliced into a "T" shape structure with a 12mm thick steel plate and is directly welded and fixed on the trolley body frame, ensuring the safety and stability of the pipe during the carrying process. Through the cooperation of the first pipe support 131 and the second pipe support 132, the moving unit 1 can easily complete various pipe carrying tasks, greatly improving the work efficiency and safety.

[0038] The bolt 14 and the bolt hole 15 are appropriately sized to connect and fix the pipe support component 13 and the trolley body frame 11. By tightening the bolt 14, sufficient pre-tightening force and friction force can be generated to ensure the stability and reliability of the connection.

[0039] In actual application, the operating personnel can flexibly select and adjust the position of the first pipe support 131 according to the specific size of the pipe to be transported. Through the bolt 14 connection mode, the first pipe support 131 can be firmly installed at the specified position on the trolley frame body 11, realizing effective support and fixation of the pipe. This not only simplifies the pipe loading and fixation process, but also significantly improves the work efficiency, solving the problem of the traditional transport trolley being difficult to adapt to different specifications of pipes due to the fixed size

[0042] The first pulley 211 is arranged at the entrance of the coke oven basement to ensure that the steel wire rope can be smoothly drawn out from the coke oven basement and moved along the predetermined path.

[0043] The second pulley 212 is arranged at the front end of the winch 22, i.e., the end of the winch output or receiving the steel wire rope, to ensure that the steel wire rope can be smoothly wound and unwound, preventing the steel wire rope from knotting or excessive wear.

[0044] The winch 22 is the power source of the towing device, which generates power through a driving mechanism (such as a motor, a hydraulic system, etc.) to drive the winding and unwinding of the steel wire rope. When the winch rotates, the steel wire rope is wound or unwound accordingly, thereby realizing the traction function.

[0045] The steel wire rope 23 is a traction rope, one end of which is connected to the trolley main body frame 11, and the other end is connected to the winch 22 through the pulley component 21.

[0046] In practical application, the dragging device improves the ability of transporting large-diameter pipelines in limited space, not only greatly reduces the dependence on human resources, effectively reduces the construction cost, but also greatly speeds up the engineering progress, ensures the project to be delivered on time. At the same time, the device reduces the direct contact of the pipeline with the surrounding completed structures in the transportation process through the traction unit, effectively avoids the damage caused by collision, and guarantees the engineering quality and the neatness of the site environment.

[0047] The working principle of the utility model is as follows:

[0048] Step one: preparation and connection: hoist the coke oven basement gas main to the coke oven end table side basement entrance, directly rest the gas main on the trolley, use the steel wire rope to connect the traction lifting lugs on the trolley, and ensure the connection firm through the clasp ring.

[0050] Step three: traction and positioning: start the winch, control the movement of the trolley through the winch brake system, gradually pull the trolley, and make it carry the gas main to move along the predetermined route to the designated position of the basement.

[0051] After reaching the designated position, stop the winch, and complete the transportation process. Those skilled in the art can easily understand that the above description is only a preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
