Description

Technical Field

[0001] This utility model relates to the field of pipeline installation and construction technology, specifically to a liftable pipeline installation device. Background Technology

[0002] In the fields of energy, water conservancy, and other infrastructure construction, pipeline transportation, as an efficient and stable mode of transport, is increasingly being applied in mountainous areas. Mountainous regions possess abundant resources, leading to a growing demand for pipeline transportation. Steep slopes in mountainous areas are critical sections for pipeline laying, and the quality and efficiency of pipeline installation directly determine the construction progress and operational safety of the entire pipeline project.

[0003] In the pipeline construction process on steep slopes in mountainous areas, stable pipeline transportation is a crucial prerequisite for ensuring the smooth progress of subsequent hoisting operations. Only by safely and smoothly transporting the pipeline to the construction site on the steep slope can subsequent hoisting, positioning, docking, and installation procedures be carried out in an orderly manner. If there are unstable issues during pipeline transportation, it will not only lead to pipeline collisions and damage, but also delay the hoisting operation and even cause safety accidents, directly affecting the overall construction efficiency.

[0004] However, pipeline construction on steep mountain slopes faces extremely severe challenges. On the one hand, steep mountain slopes often have numerous terrain obstacles such as gullies, protruding rocks, and irregular vegetation cover, resulting in extremely poor ground flatness and making it difficult to form a stable transportation and construction operation surface. On the other hand, the vertical height difference of steep slopes is large, and the horizontal space of the construction area is narrow, making it difficult for both pipeline transportation equipment and hoisting equipment to move flexibly and be positioned accurately in this environment.

[0005] In current pipeline installation and construction, crawler cranes and truck cranes are the most widely used lifting equipment. They can efficiently complete pipeline lifting operations in flat and gentle slope conditions. However, for construction scenarios on steep mountain slopes, these two types of equipment have obvious applicability defects. For example, although crawler cranes have a certain off-road capability, the steep slopes and complex terrain of mountainous sections can significantly reduce the support stability of crawler cranes, making them prone to tipping over. In addition, crawler cranes are large and difficult to adjust their working position in narrow construction spaces, failing to meet the precision requirements of pipeline lifting on steep slopes. As for truck cranes, they have higher requirements for the bearing capacity and flatness of the construction ground. Soft ground or uneven slopes on steep mountain sections cannot provide a stable support foundation for truck cranes, causing them to be unable to carry out operations normally, and even potentially leading to equipment damage and safety accidents due to ground subsidence.

[0006] At the same time, existing pipeline transportation methods are also unsuitable for steep mountain slopes. Traditional construction methods rely heavily on manual labor with simple tools such as rollers and crowbars to transport pipelines, which is not only extremely inefficient, but also prone to causing pipelines to slip and become uncontrollable on steep slopes due to slippery ground and terrain obstacles, posing serious safety hazards.

[0007] In summary, due to the challenges in pipeline transportation and the insurmountable limitations of crawler cranes and truck cranes in pipeline installation on steep mountain slopes, pipeline installation on these slopes often faces problems such as low efficiency, high safety risks, and soaring construction costs, severely hindering the progress of pipeline projects in mountainous areas. Therefore, developing a specialized device that can solve the problem of stable pipeline transportation, adapt to the complex terrain and limited construction space of steep mountain slopes, and effectively address the challenges of pipeline installation on steep slopes has become a critical issue urgently needing to be addressed in the field of mountainous pipeline construction.

Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood in conjunction with the accompanying drawings and according to the specific circumstances.

[0021] Example 1 See attached Figures 1-7 This embodiment discloses a liftable pipe installation device, the specific structure of which is as follows: The main frame includes several main beams 1. For example, four I28a I-beams can be selected as main beams 1, placed parallel to the pipeline transportation direction, and the length of the main beams 1 can be set to 4m. The main frame also includes several crossbeams 2. For example, three I28a I-beams can be selected as crossbeams 2 between two main beams 1, perpendicular to the main beams 1 and welded at intervals between the two main beams 1, so that the main beams 1 and crossbeams 2 form a U-shaped frame structure, and the length of the crossbeams 2 can be set to 3.5m. On the inner side of the U-shaped frame structure, herringbone diagonal braces 3 made of I28a I-beams are symmetrically welded, and each herringbone diagonal brace 3 forms a triangular support with the crossbeams 2 and the main beams 1. At the same time, connecting diagonal braces 4 made of I14 I-beams are welded transversely between two crossbeams 2 and / or two main beams 1 to enhance the overall rigidity of the main frame.

[0022] The fixing components are used to securely hold the pipe to be hoisted on the main frame. Specifically, high-strength nylon self-tightening cables can be used as fixing components, including a first type of self-tightening cable 6 and a second type of self-tightening cable 7. Each chain hoist 5 is equipped with a first type of self-tightening cable 6 at a corresponding position to directly fix the pipe to be hoisted. To ensure the stability of the pipe during transportation, a second type of self-tightening cable 7 is installed on both sides of the pipe. One end of the second type of self-tightening cable 7 is connected to the pipe to be hoisted, and the other end is connected to the main frame, thereby preventing the pipe from slipping during the lowering process and causing safety hazards.

[0023] The lifting assembly is used to adjust the lifting height of the pipe to be hoisted. Specifically, two chain hoists 5 with a rated lifting capacity of 5t can be selected as the lifting assembly. The chain hoists 5 are fixedly installed at the center of the top of the frame body by welding and are spaced apart along the direction of pipe transportation. For example, the distance between the two chain hoists 5 can be 4m. The hook end of the chain hoist 5 faces downward for subsequent connection with the pipe to be hoisted.

[0024] In one specific embodiment of this application, a liftable pipe installation device further includes a movable component, which is installed at the bottom of the frame body to enable movement of the frame body. Specifically, for example, two sets of 200mm track wheels can be selected as rollers 8, and the wheel material can be 45# steel. The two sets of rollers 8 are respectively fixed to both ends of the bottom of the frame body with bolts, and the rollers 8 are arranged parallel to the main beam 1. The lateral distance between the two sets of rollers 8, which is perpendicular to the pipe transportation direction, is 3.3m.

[0025] In one specific embodiment of this application, a connecting portion is provided at the middle of a crossbeam 2 near the end of the frame body. This connecting portion is used to connect with an external traction component to achieve traction movement of the liftable pipe installation device. Specifically, the connecting portion is a perforated lug plate, which is vertically welded to the middle of the crossbeam 2. The perforated lug plate has a circular hole that mates with a retaining ring for subsequent connection with the external traction component. For example, the external traction component can be a winch.

[0026] The specific working process of using the liftable pipe installation device disclosed in this utility model for pipe hoisting construction is as follows: 1. Trial operation of the liftable pipeline installation device. To ensure the reliability of the device on steep mountain slopes, a no-load trial operation is conducted before formal use. Specifically, the assembled liftable pipeline installation device is placed on a track on a steep mountain slope or a simulated steep mountain slope, and the device is pushed along the track. At the same time, the running status of roller 8 is observed to ensure that there is no obvious track wear on roller 8.

[0027] 2. Traction Connection. The wire rope of the external traction component, i.e., the winch, is detachably connected to the perforated ear plate on the main frame beam 2 using snap rings to ensure a firm and secure connection.

[0028] 3. Lifting the pipe to the device. Use a truck crane with a 10t sling to lift the pipe to be installed. During lifting, the 10t sling should be passed longitudinally through the inside of the pipe to avoid damage to the outer wall of the pipe. Lift the pipe smoothly into the frame of the liftable pipe installation device, and adjust the position of the pipe so that the center of the pipe is aligned with the center of the device.

[0029] 4. Pipeline Fixing. At each location of the chain hoist 5 corresponding to the pipeline, two Type I self-tightening cables 6 are tied. One end of the self-tightening cable is fixed to the outer wall of the pipeline, and the other end is connected to the welding point of the crossbeam 2 of the main frame. At the same time, two Type II self-tightening cables 7 can be tied on both sides of the pipeline, perpendicular to the pipeline transportation direction. One end of the self-tightening cable is connected to the steel pipe, and the other end is connected to the main beam 1 of the main frame. All self-tightening cables are adjusted to the tensioned state to prevent the steel pipe from slipping.

[0030] 5. Start the winch and slowly and steadily lower the liftable pipe installation device. During the lowering process, arrange for a dedicated person to monitor the device's operation in real time, including the stability of the main frame, the running status of the rollers 8, and the tension of the self-tightening cable.

[0031] Once the liftable pipe installation device carries the pipe to the installation location on a steep slope in the mountainous area, the pipe installation can be completed by following these steps: The two 5t chain hoists 5 at the top of the main frame are used to simultaneously and synchronously raise and lower the chain, slowly lowering the pipe to the design elevation. The design elevation can be pre-measured and marked with a level. During the lowering process, the surveyor will track and measure the entire process to ensure that the pipe section is installed in the correct position.

[0032] Adjust the pipe position to align the current pipe with the pipe openings of the pipe sections installed before and after. After alignment, weld short welds around the pipe openings to temporarily fix the pipe sections before and after. Then, use a layered welding process to weld the entire weld layer by layer from the inside of the pipe opening outwards.

[0033] After the weld is completed and cooled to room temperature, remove the self-tightening cable of the fixing component, operate the chain hoist 5 to separate the hook from the pipe, and start the winch to pull the lifting pipe installation device out of the installation area; repeat the above steps to hoist, lower and install the next section of pipe until the installation of the pressure steel pipe in the steep slope section of the mountain is completed.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
