Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to a jacking device for pipeline installation in confined spaces. Background Technology

[0002] Pipeline installation is a core component of modern urban infrastructure and industrial production, stemming from the urgent need for efficient and safe resource transportation. Whether it's municipal water supply and drainage, gas heating, or the long-distance transmission of oil, natural gas, and chemical raw materials, all rely on a vast pipeline network.

[0003] The installation of pipelines on the top of utility tunnels is a highly specialized and common construction scenario. Unlike direct burial or pipe jacking, it takes place inside an existing integrated utility tunnel. Currently, the installation of top-mounted pipelines requires hoisting. However, due to the limited space inside the utility tunnel, large pipelines and equipment are difficult to transport mechanically. Replacing pipelines laid on the top of the tunnel is also problematic because the pipelines are close to the top and there are no hoisting points, making conventional pipeline hoisting methods impossible. This necessitates heavy reliance on manpower and small machinery, posing a significant challenge to construction organization and efficiency. Therefore, this solution proposes a pipeline jacking device for replacing pipelines on the top of the utility tunnel, shortening the replacement time, improving construction efficiency, and ensuring construction safety.

[0035] See Figure 1-6 As shown, this utility model proposes a lifting device for installing pipes in confined spaces, characterized by comprising: a base 1 and a lifting device 2, the lifting device 2 being disposed above the base 1; the lifting device 2 including a hydraulic platform 23, a worktable 25, a support frame 20, and a drive system 3; the support frame 20 being connected between the hydraulic platform 23 and the worktable 25, the hydraulic platform 23 being detachably mounted on the base 1; the support frame 20 being divided into a first support frame 21 and a second support frame 22, the two support frames 20 being arranged parallel to each other at a certain distance; each support frame 20 including two support rods, divided into a first support rod 21 and a second support rod 22, the two first support rods 21 and the second support rod 22 being X-shapedly connected by a rotating shaft 214; the drive system 3 being connected to the support frame 20 and controlling the lifting and lowering of the support frame 20.

[0036] In this embodiment, the confined space pipe installation lifting device includes two parts: a base 1 and a lifting device 2. Before the construction preparation process, the two parts are transported to the construction pipe gallery area respectively. The lifting device 2 is installed on top of the base 1. The lifting device 2 is temporarily fixed to the base 1 by disassembly and assembly to prevent the lifting device 2 from moving during the replacement of the pipe 4.

[0037] Further, see Figure 1-4 As shown, the base 1 includes a base frame 10 and a support plate 13, with the support plate 13 located above the base frame 10. The surface of the support plate 13 has a certain texture, which further increases the roughness of the surface of the base 1 and prevents the lifting device 2 from moving. Preferably, in this embodiment, the support plate is made of a steel plate with a certain pattern.

[0038] The base frame 10 includes four lifting rods 11; the lifting rods 11 are fixed to the bottom of the support plate 13 symmetrically at a certain distance from each other; a stabilizing rod 12 is provided between adjacent lifting rods 11. In this embodiment, there are four lifting rods 11 and four stabilizing rods 12. The stabilizing rod 12 is arranged perpendicularly to the lifting rods 11, and the stabilizing rod 12 connects two adjacent lifting rods 12 to improve the stability of the base 1; the lifting height of the lifting rods 11 is limited, and the height of the base 11 is in the range of 850-1250mm; preferably, in this embodiment, the height of the base 1 is 1200mm, and the base frame 10 is made of 10# channel steel.

[0039] Specifically, the base 1 further includes a plurality of pulleys 14, which are fixed below the base frame 10 for moving the base 1; see also Figure 1 , 2 As shown, in this embodiment, each lifting rod 11 is provided with a pulley 14, and the number of pulleys 14 is four; preferably, the pulley 14 is a universal pulley with a locking device.

[0040] Specifically, see Figure 3 , 4 As shown, multiple limiters 231 are provided between the worktable 25 and the hydraulic platform 23, with the limiters 231 located at the corners of the hydraulic platform 23. In this embodiment, there are four limiters 231 located at the four corners of the hydraulic platform 23, limiting the distance between the upper and lower worktable 25 and the hydraulic platform 231. The drive device 3 is located between the worktable 25 and the hydraulic platform 23. The limiters 231 ensure sufficient space for the drive device 3 during the retraction of the worktable 25 and also act as a buffer.

[0041] Specifically, see Figure 5 , 6As shown, a first support frame 21 and a second support frame 22 are provided between the workbench 25 and the hydraulic table 23. The first support frame 21 and the second support frame 22 are connected by two connecting rods, including a first connecting rod 214 and a second connecting rod 215. The first connecting rod 214 and the second connecting rod 215 are located on the same side of the two support frames 20.

[0042] The drive system 3 includes a motor 31, a hydraulic cylinder 32, a controller 33, a hydraulic pump 34, and an oil tank 35. The two ends of the hydraulic cylinder 33 are respectively located on the two connecting rods. One end of the hydraulic cylinder 33 is connected to the oil outlet of the hydraulic pump 34 via a single return pipe. The oil inlet of the hydraulic pump 34 is connected to the oil tank 35 via an inlet pipe. The motor 31 is connected to the rotating shaft of the hydraulic pump 34. Under the power drive of the motor 31, the hydraulic cylinder 33 operates, realizing the linkage lifting and lowering of the first support frame 21 and the second support frame 22. The controller 31 is connected to the motor 32 and controls the operation of the motor 32. Specifically, the oil tank is located on the base, and the inlet pipe is connected to the hydraulic pump from the side of the base. The motor 32 and the hydraulic pump 34 are placed on the hydraulic platform 23. In this embodiment, the hydraulic cylinder 33 is a single-acting cylinder, including a hydraulic rod 331 and a hydraulic cylinder 332; the hydraulic cylinder 33 is lifted by oil inlet from a hydraulic pipe 333, and the hydraulic cylinder 33 is retracted by a spring installed inside the hydraulic cylinder 332; the head of the hydraulic rod 331 is rotatably and fixedly connected to the second connecting rod 215, and the tail of the hydraulic cylinder 332 is rotatably and fixedly connected to the first connecting rod 214; the first connecting rod 214 and the second connecting rod 215 are arranged at a certain distance in the horizontal direction, and the distance between the two connecting rods is determined according to the length of the hydraulic cylinder 33.

[0043] Further, see Figure 3 , 6 As shown, the workbench 25 also includes two fixing devices 24, which are symmetrically arranged on both sides of the upper surface of the workbench 25 to prevent the pipe 4 waiting to be replaced from rolling off. Each fixing device 24 includes multiple connectors 241, a fixing plate 242, and a locking member 243. The fixing plate 242 is connected to the workbench 25 via the connectors 241. The locking member 243 is located at the connection between the fixing plate 242 and the workbench 25, with one end connected to the fixing plate 242 and the other end connected to the workbench 25, restricting the movement of the fixing plate 242 relative to the workbench 25. In this embodiment, the connectors 241 have a hinged structure, each fixing device 24 has four hinges, and there are a total of eight hinges in the pipe construction lifting device.

[0044] The working principle of this utility model is as follows: the controller 31 controls the motor 32 to start working, and the motor 32 provides power to the hydraulic cylinder 33; the hydraulic rod 331 of the hydraulic cylinder 33 extends out of the hydraulic cylinder 332, and the hydraulic rod 331 and the hydraulic cylinder 332 support the two connecting rods 214, which further drive the two X-shaped support frames 20 to rise and fall; thereby completing the replacement of the pipe 4. A fixing device 24 is installed on the upper surface of the hydraulic platform 23. The fixing plate 242 is rotated 90° to be perpendicular to the hydraulic platform 23, and the fixing plate 242 is fixed by opening the locking piece 243, thus protecting the pipe 4 to be replaced.

[0045] During pipe replacement, the jacking unit and base are first hoisted into the pipe rack using a crane or overhead crane, and the jacking unit is installed on top of the base. At the location of the pipe to be removed, the jacking device holds the pipe in place, and after cutting off both ends, fixing devices are used on both sides to prevent the pipe from rolling off the hydraulic platform. Then, the old pipe is slowly lowered, and finally, the pipe is removed from the jacking device. When installing the new pipe, it is first cut to the same length as the removed pipe. Then, the new pipe is moved to the jacking platform and slowly lifted to the predetermined position. The pipe is then moved to the existing pipe rack. This process is repeated until all pipes requiring replacement are replaced.

[0046] This utility model proposes a jacking device for pipe installation in confined spaces. It breaks down a relatively large device into two parts, solving the problem of inaccessible space in pipe racks and meeting the construction needs of pipe section installation in confined spaces such as pipe racks. Pulleys are installed under the base to facilitate the movement of the jacking device, making installation, transportation, and hoisting convenient. It can be assembled at any time when construction is required. The device is equipped with a fixing mechanism to further prevent pipe rolling. During pipe replacement construction, this not only improves construction efficiency but also ensures the safety of construction personnel.
