Description

Technical Field

[0001] The invention relates to the technical field of industrial and civil construction engineering, and relates to an auxiliary device for installing a large-section pipeline. Background Art

[0002] When installing pipes at relatively high positions indoors, it is impossible to use large equipment for lifting due to the relatively small interior of the building. Therefore, most people currently use the method of pre-embedded expansion bolts on the floor slab and use them as lifting points to lift the pipes upwards. However, this method is labor-intensive and poses great risks to workers during the operation.

[0003] CN 208535312 U discloses an indoor pipe installation device, CN 213177090 U discloses a fire protection pipe installation device, and CN 212318969 U discloses a pipe installation device. However, these pipe installation devices generally suffer from the following issues: 1) poor adaptability: some lifting devices have poor adaptability to pipes of varying diameters, weights, and shapes; 2) poor operational flexibility: some lifting devices lack operational flexibility in confined spaces; 3) low precision: while lifting devices help improve control of pipe lifting height, they still lack precise adjustment of horizontal position and angle; and 4) poor stability and a low safety factor: some lifting devices may wobble when lifting heavy or long pipes. This not only affects the accuracy of pipe installation but also poses potential safety risks.

[0004] Therefore, it is of great practical significance to develop a pipeline installation device with good adaptability, flexible operation, good operation stability and high adjustment accuracy. Summary of the Invention

[0005] Due to the above-mentioned defects in the prior art, the present invention provides a pipeline installation device with good adaptability, flexible operation, good operation stability and high adjustment precision, so as to reduce the high-intensity physical labor of workers in carrying heavy pipelines, overcome the difficulty of manual operation in accurately controlling the pipeline lifting speed, height and horizontal position, avoid problems such as pipeline docking misalignment, improve operation accuracy, reduce the risk of working at heights, reduce the risk of pipelines falling or workers falling when manually lifting pipelines with simple tools, improve installation efficiency, speed up the lifting speed and enhance process consistency, so as to better meet the needs of mechanical and electrical pipeline installation and ensure the smooth progress of the project.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An auxiliary device for installing large-section pipes, comprising a device base, a lifting assembly, a lifting base, an angle adjustment base, and a pipe placement device;

[0008] A lifting assembly is installed on the base of the equipment. The lifting base is movably connected to the lifting assembly and the lifting base can be lifted and lowered in the vertical direction under the action of the lifting assembly. The lifting base is horizontally arranged and an angle adjustment base is installed on it. One side of the lifting base is connected to the angle adjustment base through a rotating pair, and the other side is provided with an angle adjustment device that moves in the vertical direction and the angle adjustment device is fixed away from the lifting base end and the angle adjustment base. A pipe placing device for placing pipes is fixed on the angle adjustment base.

[0009] The large-section pipeline installation auxiliary device of the present invention has a reasonable structural design, which can ensure that the pipeline can be easily and quickly loaded into the integrated support bracket, and can complete the efficient installation of the pipeline without the cooperation of other equipment such as lifting equipment, thereby meeting the various requirements of the construction site to the greatest extent. At the same time, it can ensure the stability of the pipeline lifting and installation process, has good operational safety, good adaptability, flexible operation and high adjustment precision, and has good application prospects.

[0010] The above-mentioned auxiliary device for installing large-section pipes has the following advantages:

[0011] 1. Improve capabilities

[0012] 1. Stronger carrying capacity

[0013] It can easily handle the weight of large-section pipes. For example, in HVAC projects, the new device can stably lift large-diameter, thick-walled chilled water and cooling water pipes to the required height. Existing technologies may encounter difficulties or pose safety risks when lifting such heavy pipes. In contrast, the new device can withstand higher loads, ensuring smooth lifting of large-section pipes.

[0014] 2. Suitable for a wider range of sizes

[0015] It can accommodate a wider range of pipe cross-sectional sizes. Existing technologies may have strict limitations on pipe size, but the new device, through its innovative design, adjustable clamping mechanism, or more flexible lifting structure, can accommodate large-section pipes of varying diameters and lengths. This provides a more versatile solution for various large-scale pipeline installation projects, reducing the need for multiple different devices due to varying pipe sizes.

[0016] 2. Operational Efficiency

[0017] 1. Rapid lifting and installation

[0018] The optimized mechanical structure and power system for lifting and installation have resulted in faster lifting and more efficient installation. The new device can significantly shorten the installation cycle for large-section pipes, significantly improving construction schedules compared to existing technologies.

[0019] 2. Simplify the operation process

[0020] The design is more user-friendly and the operation process is simpler. Operators can master the new device after simple training, reducing the time wasted and errors caused by complex operations. Compared with the cumbersome operation steps and multi-step coordination of existing technologies, the new device improves overall work efficiency and reduces labor costs and construction difficulty.

[0021] 3. Safety performance

[0022] 1. Enhanced stability

[0023] The structural design emphasizes stability, employing more robust support and connection methods. When lifting and installing large-section pipelines, the new device effectively resists pipeline sway and external forces, reducing the risk of safety accidents caused by equipment instability.

[0024] 2. Improved safety protection measures

[0025] Equipped with comprehensive safety features, including overload protection and an emergency braking system, these measures provide operators with multiple safeguards during the lifting and installation process, effectively preventing potential safety incidents. Compared to existing technologies, the new device offers significant improvements in safety performance, significantly reducing safety incidents caused by improper operation or unexpected situations, and creating a safer construction environment for pipeline installation projects.

[0026] 4. Adaptability

[0027] It can better adapt to various complex construction environments. Whether in narrow spaces, high-altitude operations or sites with obstacles, the new device can smoothly complete the lifting and installation of large-section pipes through flexible design and adjustment.

[0028] As the preferred technical solution:

[0029] The aforementioned large-section pipe installation auxiliary device comprises a base plate, the bottom of which is equipped with multiple base wheels and anti-roll legs at each of its four corners. The base plate can be moved on the work surface as needed, and the anti-roll legs enhance the stability of the lifting operation, ensuring construction safety.

[0030] As described above, in the auxiliary device for installing large-section pipes, the pipe placement device has a plurality of mutually parallel pipe placement grooves for placing pipes on the side away from the angle adjustment base.

[0031] The large-section pipe installation auxiliary device as described above, wherein the lifting assembly comprises two V-shaped lifting frames arranged opposite to each other;

[0032] The gate-shaped lifting frame includes two vertical parts parallel to each other and a horizontal part connecting the two vertical parts;

[0033] Lifting slide rails are provided on opposite sides of the two vertical parts, and lifting devices are also arranged on the sides of the vertical parts.

[0034] In the aforementioned auxiliary device for installing large-section pipes, the lifting base comprises a horizontally arranged lifting chassis;

[0035] Lifting side frames perpendicular to the lifting base are provided on both sides of the lifting base, and lifting pulleys matching the lifting slide rails are fixed on the sides of the lifting side frames. The lifting base is fixed with angle adjustment devices and fixing pin seats 1 respectively located on both sides of the lifting base.

[0036] In the aforementioned auxiliary device for installing large-section pipes, the angle adjustment base includes an angle adjustment base frame;

[0037] An angle adjustment device connector and a fixed pin seat II are fixed to both sides of the angle adjustment chassis respectively. The angle adjustment device connector is fixed to the angle adjustment device, and the fixed pin seat I and the fixed pin seat II are fixed by a fixing pin.

[0038] The present invention also provides a method for using the large-section pipeline installation auxiliary device as described above, comprising the following steps:

[0039] (1) Place the large-section pipe to be installed on the pipe placement device of the large-section pipe installation auxiliary device;

[0040] (2) Move the large-section pipe installation auxiliary device to the installation position and lower the anti-roll legs;

[0041] (3) After the lifting base is lifted to a certain height by the lifting device, the inclination angle of the pipe placement device is adjusted by the angle adjustment device so that the raised end of the large-section pipe is higher than the top surface of the integrated support and hanger crossbar;

[0042] (4) Retract the anti-roll support legs, move the large-section pipe installation auxiliary device a certain distance toward the tilted end of the large-section pipe, so that the front end of the pipe (at a higher elevation) extends into the support bracket, and move the rear end of the pipe vertically to the side of the support bracket to ensure that it does not affect the lifting of the pipe;

[0043] (5) Lift the lifting base and adjust the angle adjustment device at the same time, that is, keep the height of the raised end of the large-section pipe unchanged, and gradually raise the height of the other end to the level of the large-section pipe;

[0044] (6) Adjust the horizontal position of the large-section pipe installation auxiliary device so that both ends of the large-section pipe are located above the integrated support bracket, thus completing the large-section pipe installation auxiliary operation.

[0045] The large-section pipe installation auxiliary device is brought to the site after the installation of the integrated support and hanger at the electromechanical pipeline installation site is completed; the large-section pipe installation auxiliary device loads the large-section pipes directly in the pipe stacking area. The large-section pipe installation auxiliary device is both an equipment lifting and installation tool and a short-distance transportation tool for on-site pipes. The application of this device can greatly save a lot of material handling time and improve pipeline installation efficiency.

[0046] The above method is easy to operate and can stably and efficiently complete the installation of large-section pipes.

[0047] As the preferred technical solution:

[0048] The method of use as described above further includes the following steps:

[0049] (7) Adjust the lifting device to lower the lifting base to the lowest position, move the large-section pipe installation auxiliary device to the location where the large-section pipes are placed, and repeat (1) to (6) until all large-section pipes are installed.

[0050] As described above, in step (2), after the large-section pipe installation auxiliary device is moved to the installation position and before the tilting legs are lowered, the position of the large-section pipe installation auxiliary device needs to be adjusted to ensure that the pipeline layout direction is perpendicular to the integrated support bracket.

[0051] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.
