Description

Technical Field

[0001] This utility model relates to the field of municipal construction accessories technology, and in particular to a protective device for pipeline construction to prevent collisions. Background Technology

[0002] In pipeline construction, whether it's underground pipeline laying, overhead pipeline installation, or pipeline projects traversing complex terrain and building areas, pipeline safety is always of paramount importance. Ensuring that pipelines are not damaged during construction has a crucial impact on the overall project quality, schedule, and subsequent safe operation.

[0003] Current common pipeline collision protection methods have many obvious shortcomings. On the one hand, wrapping the pipeline surface with flexible materials such as foam boards or plastic films provides only extremely limited cushioning. When faced with slightly stronger impacts such as accidental collisions with construction machinery or falling heavy objects, they are completely ineffective in protecting the pipeline, significantly reducing their protective performance. On the other hand, setting up simple obstacles such as wooden fences or rope barriers around the pipeline, while providing some warning, cannot fundamentally prevent direct impacts from external forces. In actual construction scenarios, these barriers can easily be breached if construction workers make operational errors or site management is negligent, leaving the pipeline still exposed to high risk. Furthermore, while conventional low-level gas pipeline collision protection supports can protect gas pipelines, the components of these supports are mostly fixed connections, making disassembly and replacement cumbersome and inconvenient. Moreover, existing protective measures lack adaptability to different pipeline specifications and construction environments, often requiring temporary on-site assembly or modification, making standardized and regulated construction difficult, resulting in low construction efficiency and inconsistent quality.

[0004] Existing simple protective measures are mostly for single use and have poor durability. In long-term or large-scale pipeline construction projects, material costs will continue to accumulate and increase. At the same time, frequent replacement of protective devices also requires a lot of manpower and time costs, which undoubtedly hinders the efficient progress of the project and increases the overall cost of the project. Utility Model Content

[0005] To address existing problems, this utility model provides a protective device for pipeline construction collision prevention, aiming to provide a more effective, reliable, and economical collision prevention solution for pipeline construction.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A protective device for pipeline construction collision prevention includes longitudinal steel pipes, arc-shaped steel pipes, multi-directional pulleys, anti-collision steel bars, and inclined steel pipes; there are multiple longitudinal steel pipes, which are parallel to the length of the pipeline; at least two longitudinal steel pipes are located below the others, and multi-directional pulleys are installed at their bottoms; at least one longitudinal steel pipe is located above the others, and it is connected to the two longitudinal steel pipes equipped with pulleys through an inclined steel pipe; the two longitudinal steel pipes equipped with pulleys are connected by an arc-shaped steel pipe; the anti-collision steel bars extend outward from the longitudinal steel pipes or the inclined steel pipes.

[0008] As a further improvement of this utility model, the longitudinal steel pipe located on the upper side is hinged to the oblique steel pipe; the two ends of the arc steel pipe are respectively slidably connected to two longitudinal steel pipes equipped with pulleys.

[0009] As a further improvement of this utility model, the anti-collision steel strip extending outward from the longitudinal steel pipe located on the upper side is in the horizontal direction.

[0010] As a further improvement of this utility model, the anti-collision steel strip extending outward from the longitudinal steel pipe forms an angle greater than 45° with the horizontal direction.

[0011] As a further improvement of this utility model, the anti-collision steel strip includes a steel strip end and a steel strip tip, with the steel strip tip located on the outside of the device and a warning sign provided at the steel strip tip.

[0012] As a further improvement of this utility model, anti-collision rubber is provided at the tip of the anti-collision steel strips on both outer sides along the length of the longitudinal or oblique steel pipe.

[0013] As a further improvement of this utility model, the density of the anti-collision steel strips on the longitudinal steel pipe is higher than that on the diagonal steel pipe.

[0014] As a further improvement of this utility model, the multi-directional pulley includes a pulley top plate, pulley side plates, high-strength bolts, and pulleys; the upper part of the pulley top plate is connected to the bottom of the longitudinal steel pipe, the lower part of the pulley top plate is connected to two pulley side plates, a high-strength bolt is provided between the two pulley side plates, and a pulley is sleeved on the high-strength bolt.

[0015] As a further improvement of this utility model, the pulley is provided with an anti-slip rubber pad.

[0016] As a further improvement of this utility model, the multi-directional pulley also includes an anti-slip lock, which is hinged to the pulley side plate.

[0017] This utility model has the following beneficial effects:

[0018] This device, constructed from a combination of longitudinal steel pipes, arc-shaped steel pipes, multi-directional pulleys, anti-collision steel bars, and diagonal steel pipes, is a protective structure specifically designed for pipeline construction. Multiple longitudinal steel pipes, parallel to the length of the pipeline, provide the basic framework and support. Multi-directional pulleys at the bottom facilitate flexible movement of the device within the pipeline construction area. The diagonal steel pipes connect the upper longitudinal steel pipes and the lower longitudinal steel pipe equipped with pulleys, forming a triangular prism structure that enhances the device's resistance to pressure from all directions. The arc-shaped steel pipes adapt to the curved surface of the pipeline and connect the two longitudinal steel pipes equipped with pulleys, making the overall structure more robust and stable. The diagonal steel pipes extend outwards to form anti-collision steel bars, which can absorb impact forces in advance, protecting both the pipeline and the device itself, providing reliable anti-collision protection for pipeline construction.

[0019] Preferably, a longitudinal steel pipe on the upper side is hinged to an oblique steel pipe, allowing for a certain range of motion between the two pipes. When subjected to external forces such as impacts, the rotation at the hinge can buffer and disperse some of the impact force, reducing structural damage. The two ends of the arc-shaped steel pipe are slidably connected to two longitudinal steel pipes equipped with pulleys. When the device moves or is subjected to external forces, the arc-shaped steel pipe can slide relative to the longitudinal steel pipes, further dispersing stress, enhancing the adaptability and impact resistance of the device, and improving its stability and durability. At the same time, the slidable connection between the two ends of the arc-shaped steel pipe and the longitudinal steel pipes allows for appropriate adjustment of the included angle between the longitudinal steel pipes to accommodate different pipe diameters.

[0020] Preferably, the anti-collision steel strip extending outward from the longitudinal steel pipe on the upper side is horizontal. The horizontal anti-collision steel strip can form a planar guard in the horizontal direction, directly bearing the impact force in the vertical direction, and effectively blocking collisions from the horizontal direction, providing more direct protection for the pipeline and preventing the pipeline from being damaged by horizontal impacts.

[0021] Preferably, the anti-collision steel bars extending outward from the longitudinal steel pipe form an angle greater than 45° with the horizontal direction. This inclined setting avoids the psychological burden on construction workers and prevents the anti-collision steel bars from being perpendicular to the possible entry direction of construction workers, thus avoiding penetrating injuries to the human body.

[0022] Preferably, the anti-collision steel strip includes a steel strip end and a steel strip tip. The steel strip tip is located outside the device and is equipped with a warning sign. The warning sign can play a significant warning role in the pipeline construction area, reminding construction personnel and other personnel to pay attention to the existence of the device and pipeline, avoiding collision accidents due to negligence, and enhancing construction safety.

[0023] Preferably, anti-collision rubber is provided at the tips of the anti-collision steel bars on both outer sides along the length of the longitudinal or oblique steel pipe. The anti-collision rubber has good buffering performance. When the device is impacted, the anti-collision rubber can further absorb and disperse the impact force, reduce the damage to the device and pipeline, and at the same time reduce the noise generated by the impact, thus improving the construction environment.

[0024] Preferably, the density of the anti-collision steel bars on the longitudinal steel pipe is higher than that on the diagonal steel pipe, with differentiated design based on the probability and severity of impact at different locations. The longitudinal steel pipe is usually closer to the pipeline and is more likely to be impacted; increasing the density of the anti-collision steel bars on it can improve the protective capability of this part and better protect the pipeline. On the other hand, the probability of impact on the diagonal steel pipe is relatively low; appropriately reducing the density of the anti-collision steel bars can save materials and reduce costs while ensuring the overall protective effect of the device.

[0025] Preferably, the multi-directional pulley is designed in detail. The pulley top plate connects the bottom of the longitudinal steel pipe and the pulley side plate to provide stable support for the pulley. High-strength bolts are installed between the two pulley side plates and the pulley is sleeved on them, so that the pulley is firmly installed and can rotate flexibly. This type of multi-directional pulley can not only ensure the flexible movement of the device in the pipeline construction area, but also bear a certain weight, ensuring the stability of the device during the movement process and improving construction efficiency.

[0026] Preferably, the pulley is provided with an anti-slip rubber pad. The anti-slip rubber pad increases the friction between the pulley and the contact surface, preventing the device from slipping and losing control during movement, thus improving the stability and safety of the device's movement. Especially in some construction environments with complex ground conditions or dampness, it can effectively avoid accidents caused by pulley slippage.

[0027] Preferably, the multi-directional pulley also includes an anti-slip lock hinged to the pulley side plate. When the device needs to be fixed in a certain position, the pulley can be locked by operating the anti-slip lock to prevent the device from sliding, ensuring the stability of the pipeline construction process, meeting the needs of device fixing and moving in different construction scenarios, and improving the practicality and safety of the device.

[0036] Example 1

[0037] like Figure 1 As shown, a protective device for pipeline construction collision avoidance includes a longitudinal steel pipe 1, an arc-shaped steel pipe 2, a multi-directional pulley 3, a collision-resistant steel bar 4, and an oblique steel pipe 5. The longitudinal steel pipe 1 or the oblique steel pipe 5 can be made of Q235B carbon structural steel or steel pipe conforming to APISPEC 5L or GB9711 standards, with a recommended pipe diameter range of Φ406.4mm to Φ1422.4mm, covering common scenarios such as water pipelines and gas pipelines.

[0038] There are three longitudinal steel pipes 1, which are parallel to the length of the pipeline. Two longitudinal steel pipes 1 are located on the lower side relative to the others, and four multi-directional pulleys 3 are installed at their bottom. One longitudinal steel pipe 1 is located on the upper side relative to the others, and it is connected to the two lower longitudinal steel pipes 1 by an oblique steel pipe 5. The two longitudinal steel pipes 1 equipped with multi-directional pulleys 3 are connected by an arc-shaped steel pipe 2. The longitudinal steel pipes 1 or oblique steel pipes 5 extend outwards to form anti-collision steel strips 4. Specifically, the longitudinal steel pipes 1 or oblique steel pipes 5 are connected to the anti-collision steel strips 4 by threaded connections through pre-drilled holes for easy disassembly. Red and white reflective film can also be applied to the surface of the longitudinal steel pipes 1 or oblique steel pipes 5 to improve nighttime visibility.

[0039] The anti-collision steel strip 4 extending outward from the upper longitudinal steel pipe 1 is in the horizontal direction. The horizontal anti-collision steel strip 4 can form a planar protective barrier in the horizontal direction, directly bearing the impact force in the vertical direction, and effectively blocking collisions from the horizontal direction, providing more direct protection for the pipeline and preventing the pipeline from being damaged by horizontal impacts.

[0040] like Figure 2 As shown, the anti-collision steel strip 4 includes a steel strip end 6 and a steel strip tip 7. The steel strip tip 7 is located on the outside of the device, and a warning sign is provided at the steel strip tip 7.

[0041] The density of the anti-collision steel strips 4 on the longitudinal steel pipe 1 is higher than that on the diagonal steel pipe 5.

[0042] like Figure 3 As shown, the multi-directional pulley 3 includes a pulley top plate 8, pulley side plates 9, high-strength bolts 10, and pulleys 11. The upper part of the pulley top plate 8 is connected to the bottom of the longitudinal steel pipe 1, and the lower part of the pulley top plate 8 is connected to two pulley side plates 9. A high-strength bolt 10 is installed between the two pulley side plates 9, and the pulley 11 is sleeved on the high-strength bolt 10. The bottom of the longitudinal steel pipe 1 is welded to the multi-directional pulley 3 through the pulley top plate 8 to form a stable overall structure.

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 is that:

[0045] 1) The anti-collision steel strip 4 extending outward from the longitudinal steel pipe 1 forms an angle greater than 45° with the horizontal direction;

[0046] 2) Anti-collision rubber is provided at the tip 7 of the anti-collision steel strips 4 on both outer sides along the length of the longitudinal steel pipe 1 or the inclined steel pipe 5;

[0047] 3) Anti-slip rubber pads are provided on pulley 11.

[0048] The anti-collision steel strip 4 extending outward from the longitudinal steel pipe 1 forms an angle greater than 45° with the horizontal direction. This inclined setting avoids the psychological burden on construction workers and prevents the anti-collision steel strip 4 from being perpendicular to the possible entry direction of construction workers, thus avoiding penetrating injuries to the human body.

[0049] Rubber fenders or anti-collision rubber are installed on the outer sides of the anti-collision steel bars 4 on both sides along the length of the longitudinal steel pipe 1 or the diagonal steel pipe 5 to absorb impact energy.

[0050] The pulley 11 is equipped with an anti-slip rubber pad, which increases the friction between the pulley 11 and the contact surface, preventing the device from slipping and losing control during movement, thus improving the stability and safety of the device. Especially in some construction environments with complex ground conditions or dampness, it can effectively prevent accidents caused by the slippage of the pulley 11.

[0051] This embodiment is applicable to the installation of pipelines in urban areas or villages with large populations for collision protection.

[0052] Example 3

[0053] The difference between this embodiment and Embodiment 1 is that:

[0054] 1) A longitudinal steel pipe 1 located on the upper side is hinged to an oblique steel pipe 5; the two ends of the arc steel pipe 2 are respectively slidably connected to two longitudinal steel pipes 1 equipped with multi-directional pulleys 3.

[0055] 2) The multi-directional pulley 3 also includes an anti-slip lock, which is hinged to the pulley side plate 9.

[0056] A longitudinal steel pipe 1 located on the upper side is hinged to an oblique steel pipe 5, allowing for a certain range of motion between the upper longitudinal steel pipe 1 and the oblique steel pipe 5. When subjected to external forces such as impacts, the rotation at the hinge can buffer and disperse some of the impact force, reducing structural damage. The two ends of the arc-shaped steel pipe 2 are slidably connected to two longitudinal steel pipes 1 equipped with multi-directional pulleys 3. When the device moves or is subjected to external forces, the arc-shaped steel pipe 2 can slide relative to the longitudinal steel pipe 1, further dispersing stress, enhancing the adaptability and impact resistance of the device, and improving the stability and durability of the device. At the same time, the two ends of the arc-shaped steel pipe 2 are slidably connected to the longitudinal steel pipes 1, which can moderately adjust the included angle between the longitudinal steel pipes 1 to accommodate different pipe diameters.

[0057] The anti-slip lock can be fixed on the pulley top plate 8 or the pulley side plate 9. The pulley 11 can be locked by operating the anti-slip lock to prevent the device from sliding, ensure the stability of the pipeline construction process, meet the needs of device fixing and moving in different construction scenarios, and improve the practicality and safety of the device.

[0058] The component selection and assembly method of the protective device for pipeline construction collision prevention described in this embodiment:

[0059] 1. Component selection and pretreatment

[0060] Determine the steel pipe frame, arc dimensions, pulley 11 dimensions and spacing according to the pipeline construction requirements, and pre-reserve holes on the steel pipe frame for connecting anti-collision steel strips 4.

[0061] 2. Install anti-collision steel bars 4

[0062] Select anti-collision steel strip 4, process it according to the predetermined size, select a larger cross section at the end and a smaller cross section at the tip, arrange them symmetrically in the longitudinal and transverse directions, and after fixing the position, the anti-collision steel strip 4 is firmly connected to the steel pipe frame by threaded connection.

[0063] 3. Install multi-directional pulleys 3

[0064] The pulley 11 is processed and shaped according to plan, and the steel pipe frame is welded to the multi-directional pulley 3 through the pulley top plate 8 to form a stable overall structure.

[0065] 4. Positioning and fixing anti-collision devices

[0066] According to the pipeline construction requirements, the pipeline section that needs protection is located, and the protective device is moved above the pipeline to achieve the protection function of the pipeline under construction.

[0067] Advantages of this utility model:

[0068] 1. By innovating and optimizing the construction technology of pipeline protection devices, the concepts of prefabricated, standardized, and green construction are introduced.

[0069] 2. The new method has a simple process, a safe and reliable frame, and good operability. The fixed steel pipe frame is small in size and easy to process. Since the pipeline adopts an external protection device, it avoids drilling holes in the pipeline during construction, which can minimize the impact on the pipeline and avoid the scrapping of the pipeline due to drilling.

[0070] 3. An arc-shaped steel pipe 2 is installed below the protection device according to the curvature of the pipeline, making it easy to erect above the pipeline. Multi-directional pulleys 3 are installed on the left and right sides for easy movement and can be used along the entire line. The pulleys 11 have fixing devices that can be precisely fixed to the weak sections of the pipeline, solving the problem of time-consuming and labor-intensive use of traditional protection devices.

[0071] 4. All materials can be prefabricated in the factory, and on-site installation is simple and convenient. The anti-collision steel strip 4 is connected to the steel pipe of the frame by welding. It can be disassembled at any time after construction. The anti-collision steel strip 4 can be recycled and reused multiple times in sync with the prefabricated steel pipe frame, which helps to reduce the waste of labor and steel pipes and other materials, and achieve the goal of cost reduction and efficiency improvement.

[0072] The above embodiments are merely one of the implementation methods for achieving the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions, and other implementation methods that are easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
