Description

Technical Field

[0001] This utility model relates to the field of tunnel pipeline installation technology, specifically to a pipeline installation device for extra-long tunnels in high-altitude and cold regions. Background Technology

[0002] With the continuous development of the highway industry, tunnels account for a significant proportion of the total highway mileage, and the number of long tunnels is also increasing. In order to improve the construction environment inside the tunnel, tunnel ventilation is particularly important.

[0003] Patent document CN211287787U discloses an auxiliary installation device for tunnel ventilation ducts, including several support units and fixed connectors. The support units are connected end-to-end to form a regular polygon structure, and the ventilation duct passes through the regular polygon structure. The regular polygon structure is a regular polygon circumscribed in the cross-section of the ventilation duct, and the regular polygon structure is fixedly connected to the initial support platform through the fixed connectors. The support unit includes a skeleton support rod and a movable sleeve. The skeleton support rods of two adjacent support units are fixedly connected, and the movable sleeve is movably fitted on the skeleton support rod. The movable sleeve and the skeleton support rod are arranged coaxially. The ventilation duct passes through the regular polygon structure circumscribed in the cross-section of the duct, ensuring the effective cross-sectional size of the ventilation duct. By setting the movable sleeve, the friction between the ventilation duct and the support unit is reduced, avoiding damage to the ventilation duct, ensuring the integrity of the ventilation duct, and effectively improving ventilation efficiency.

[0004] Although the aforementioned application documents reduce friction between the ventilation duct and the support unit, avoid damage to the ventilation duct, and ensure the integrity of the ventilation duct, there will still be exposed ducts outside the mountain during use. When encountering strong winds, there is still a probability that friction will occur between the ventilation duct and the support unit.

[0005] Therefore, a pipeline installation device for extremely long tunnels in cold and high-altitude areas is proposed to solve the problems mentioned above. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a pipeline installation device for extra-long tunnels in high-altitude and cold regions, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a bracket, wherein a rotating device for moving the air duct is mounted on the top of the bracket; The rotating device includes a connecting frame, a slide rail slidably connected to the inner wall of the connecting frame, a slider slidably connected to the inner wall of the slide rail, a vertical plate fixedly connected to the top of the slider, a cover plate hinged to the back of the vertical plate, an insertion hole opened on the top of the cover plate, a connecting rod fixedly connected to the top of the slider, an insertion rod movably passing through the top of the connecting rod, a handle fixedly connected to the top of the insertion rod, a spring movably sleeved on the outer wall of the insertion rod, and a baffle movably sleeved on the outer wall of the insertion rod.

[0008] Preferably, the insertion rod is inserted into the inner wall of the insertion hole, and the two ends of the spring are respectively fixedly connected to the bottom of the connecting rod and the top of the baffle.

[0009] Preferably, a plurality of rubber blocks are fixedly connected to the inner wall of the slider.

[0010] Preferably, the cover plate is composed of two arc-shaped plates, which are hinged together by a hinge rod.

[0011] Preferably, the top of the bracket is equipped with a lubrication device to improve the smoothness of the slider sliding on the inner wall of the slide rail.

[0012] Preferably, the lubrication device includes an oil groove, which is formed at the bottom of the inner wall of the slide rail. A fixing rod is fixedly connected to the side of the slider, a pressing plate is fixedly connected to the side of the fixing rod, a fixing plate is fixedly connected to the side of the slide rail, and an oil bladder is fixedly connected to the top of the fixing plate.

[0013] Preferably, an oil outlet pipe is fixedly connected to the side of the oil bladder, an oil inlet is fixedly connected to the top of the oil bladder, a one-way valve is fitted on the outer wall of the oil outlet pipe, and a valve is fitted on the outer wall of the oil inlet.

[0014] Compared with the prior art, this utility model provides a pipeline installation device for extra-long tunnels in high-altitude and cold regions, which has the following beneficial effects: First, it enables rapid installation and fixation of air ducts. At the same time, in strong wind environments, rubber blocks are used to increase the coefficient of friction, allowing the air duct to slide appropriately within the slide rail, effectively preventing friction between the air duct and the external structure, protecting the air duct from damage, and solving the problem of air duct friction with the support unit in strong winds.

[0015] Second, during the sliding process of the slider, the oil bladder is squeezed by the extrusion plate, causing the lubricating oil to be sprayed onto the inner wall of the oil groove. This significantly improves the smoothness of the slider sliding in the slide rail, reduces the frictional resistance during the sliding process, improves the operating efficiency and reliability of the device, and ensures the smooth progress of the duct installation process.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 See Figures 1-4 This embodiment provides a pipeline installation device for extra-long tunnels in cold and high-altitude areas, including a bracket 1, with a rotating device 2 for moving the duct on the top of the bracket 1. The rotating device 2 includes a connecting frame 21, with a slide rail 22 slidably connected to the inner wall of the connecting frame 21. A slider 23 is slidably connected to the inner wall of the slide rail 22. A vertical plate 24 is fixedly connected to the top of the slider 23. A cover plate 25 is hinged to the back of the vertical plate 24. An insertion hole is provided on the top of the cover plate 25. A connecting rod 26 is fixedly connected to the top of the slider 23. An insertion rod 27 is movably inserted through the top of the connecting rod 26. A handle 28 is fixedly connected to the top of the insertion rod 27. A spring 210 is movably fitted on the outer wall of the insertion rod 27. A baffle 29 is movably fitted on the outer wall of the insertion rod 27. The bracket 1 is made of high-strength alloy material, capable of withstanding the harsh environment of high-altitude and cold regions, as well as the weight and pressure of the air duct. The connecting frame 21 and the bracket 1 are fixedly connected by bolts to ensure the stability of the rotating device 2 during installation. The slide rail 22 has an "I" shaped cross section, and the slider 23 matches the shape of the slide rail 22, allowing the slider 23 to slide smoothly within the slide rail 22, thereby driving the duct to move. The vertical plate 24 provides an installation base for the cover plate 25. The arc-shaped structure of the cover plate 25 can better fit the shape of the duct, providing good support and fixation for the duct. The diameter of the insertion hole is slightly larger than the diameter of the insertion rod 27, making it easy for the insertion rod 27 to be smoothly inserted into the insertion hole to fix the duct. The outer wall of the handle 28 is covered with a non-slip rubber sleeve for easy operation by staff. The spring 210 allows the insertion rod 27 to automatically pop out when no external force is applied, facilitating the disassembly of the duct. The diameter of the baffle 29 is larger than the diameter of the insertion rod 27, preventing the spring 210 from falling off the insertion rod 27.

[0020] The insertion rod 27 is inserted into the inner wall of the insertion hole. The two ends of the spring 210 are fixedly connected to the bottom of the connecting rod 26 and the top of the baffle 29, respectively. The insertion rod 27 fits tightly with the insertion hole, capable of withstanding a certain amount of tension and pressure, ensuring the duct will not loosen after installation. The spring 210 is made of high-quality stainless steel, possessing good elasticity and corrosion resistance, allowing for long-term use in harsh environments at high altitudes and cold regions without easily failing. The free length and compressed length of the spring 210 are precisely calculated, providing sufficient elastic force when the insertion rod 27 is inserted into the insertion hole, while facilitating the installation and removal of the duct. The top of the baffle 29 also features anti-slip textures, increasing friction between the hand and the baffle 29, making it easier for operators to handle the insertion rod 27.

[0021] Multiple rubber blocks 211 are fixedly connected to the inner wall of the slider 23. The rubber blocks 211 are evenly distributed on the inner wall of the slider 23 and fit tightly against the slide rail 22, providing uniform support force and making the slider 23 move more smoothly within the slide rail 22. At the same time, the rubber blocks 211 also have a certain vibration damping effect, which can reduce the vibration of the duct during installation and use and improve the stability of the duct installation.

[0022] The cover plate 25 consists of two arc-shaped plates, which are hinged together by a hinge rod.

[0023] In practical use, the above-mentioned equipment is operated by prying open the cover plate 25, causing it to rotate counterclockwise around the hinge point of the vertical plate 24. The air duct is then passed between the slider 23 and the cover plate 25. Pulling the handle 28 causes the insertion rod 27 to rise, which in turn causes the baffle 29 to rise. The baffle 29 then compresses the spring 210, causing the cover plate 25 to fall. Releasing the handle 28 causes the spring 210 to descend, and the insertion rod 27 is inserted into the inner wall of the insertion hole to complete the installation. At the same time, when facing strong winds, the rubber block 211 increases the coefficient of friction between the air duct and the slider 23, allowing the air duct to slide on the inner wall of the slide rail 22 via the slider 23 when encountering strong winds, thus preventing friction between the air duct and the outside environment.

[0024] Example 2 See Figures 1-4 Based on Embodiment 1, the top of the bracket 1 is equipped with a lubrication device 3 for improving the smoothness of the slider 23 sliding on the inner wall of the slide rail 22.

[0025] The lubrication device 3 includes an oil groove 31, which is located at the bottom of the inner wall of the slide rail 22. A fixing rod 36 is fixedly connected to the side of the slider 23. A pressing plate 37 is fixedly connected to the side of the fixing rod 36. A fixing plate 32 is fixedly connected to the side of the slide rail 22. An oil bladder 33 is fixedly connected to the top of the fixing plate 32.

[0026] An oil outlet pipe 35 is fixedly connected to the side of the oil bladder 33, and an oil inlet 34 is fixedly connected to the top of the oil bladder 33. A one-way valve is installed on the outer wall of the oil outlet pipe 35, and a valve is installed on the outer wall of the oil inlet 34.

[0027] When the above-mentioned device is used, when the slider 23 slides, it drives the fixed rod 36 to descend, the fixed rod 36 drives the extrusion plate 37 to descend, and the extrusion plate 37 extrudes the oil bladder 33. The lubricating oil inside the oil bladder 33 will be sprayed from the oil outlet pipe 35 to the inner wall of the oil groove 31 due to the extrusion of the extrusion plate 37, which improves the smoothness of the slider 23 sliding on the inner wall of the slide rail 22.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
