Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a pipeline positioning device for highway tunnels. Background Technology

[0002] Tunnels are one of the most common passages on highways, often built in mountains. To ensure safety during tunnel operation, drainage and ventilation pipes are usually installed inside the tunnel to ensure air quality and drainage. This requires the installation of drainage pipes and ventilation pipes during tunnel construction.

[0003] The existing methods for installing tunnel ductwork mostly involve first using lifting equipment to raise the duct to the installation position, then continuously raising the duct. Workers at a height use bolts and other structures to position the duct before the lifting equipment moves on to the next section. This positioning method requires continuous lifting, making it difficult to quickly raise the next section of duct. Furthermore, using bolts and other structures for duct positioning is inefficient, directly impacting the overall installation efficiency and indicating room for improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a highway tunnel pipeline positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipeline positioning device for highway tunnels includes a lifting frame. Four mounting bolts are threaded onto the lower surface of the lifting frame. A groove is formed on the lower surface of the lifting frame, and a positioning shaft is fixedly connected to the inner wall of the groove. Two sliders are slidably connected to the inner wall of the groove, and positioning components are fixedly connected to the lower surfaces of both sliders. Each positioning component includes a connecting block, and a first positioning frame and a second positioning frame are fixedly connected to the lower surface of the connecting block. A rotating groove is formed on the lower surface of the first positioning frame, and an arc-shaped base is rotatably connected to the inner wall of the rotating groove via a rotating shaft. A threaded hole is formed on the front side of the arc-shaped base. A positioning groove is formed on the lower surface of the second positioning frame, and locking bolts are threaded onto the opposite sides of the two second positioning frames corresponding to the positioning grooves. The lifting frame can be fixedly installed at the top of the tunnel using the four mounting bolts.

[0007] Preferably, the position of the positioning groove corresponds to the position of the arc-shaped base, the locking bolt is adapted to the threaded hole, the lower surface of the connecting block is fixedly connected to a pressing mechanism, the arc-shaped base can rotate around the rotating axis and be locked in the positioning groove, and the locking bolt can lock the arc-shaped base in the positioning groove.

[0008] Preferably, the clamping mechanism includes fixed frames, with strip grooves on the opposite sides of the two fixed frames. A movable block is slidably connected to the inner wall of the fixed frame, and a connecting rod is fixedly connected to the lower surface of the movable block. An arc-shaped lower pressure plate is fixedly connected to the bottom end of the connecting rod. The position of the arc-shaped lower pressure plate corresponds to the position of the arc-shaped base support. After the arc-shaped lower pressure plate moves down, it can cooperate with the arc-shaped base support to perform upper and lower clamping and positioning of the air duct, ensuring the stability of the air duct.

[0009] Preferably, a U-shaped frame is fixedly connected to the opposite sides of both fixed frames. An adjusting screw is rotatably connected to the inner bottom wall of the U-shaped frame, and a transmission block is slidably connected to the inner wall of the U-shaped frame. By rotating the adjusting screw, the transmission block and the movable block can be driven to move down quickly.

[0010] Preferably, the transmission block is threadedly connected to the adjusting screw, and one end of the transmission block away from the inner wall of the U-shaped frame extends through the strip groove into the interior of the fixed frame and is fixedly connected to the movable block.

[0011] Preferably, the front of the hoisting frame has a strip-shaped hole that communicates with the interior of the slide groove. Both sliders are fixedly connected to threaded rods on their front sides, and both threaded rods are threaded with locking nuts.

[0012] Preferably, the front ends of both threaded rods pass through the strip hole and extend to the front of the lifting frame, and the locking nut is located on the surface of the threaded rod extending out of the front of the lifting frame. The locking nut can lock the position of the threaded rod and the slider, thereby ensuring the stability of the air duct after docking and assembly.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up the positioning component, the air duct can be pre-supported during the lifting process, allowing the air duct to remain suspended under the support of the two arc-shaped base supports. This eliminates the need for the lifting equipment to continuously lift the air duct, making it easier for the lifting equipment to lift the next air duct. Furthermore, by adjusting the screw, the arc-shaped lower pressure plate can be driven to descend and cooperate with the arc-shaped base supports to clamp and position the air duct. This not only improves the efficiency of the air duct installation process but also ensures the stability of the air duct after installation.

[0015] 2. Through the coordinated design of the threaded rod, locking nut, slider, and positioning shaft, the threaded rod can drive the slider to slide left and right on the surface of the positioning shaft during use. This changes the lateral position of the two sets of air ducts, facilitating their docking and enabling quick assembly. The docking process is also more stable. After the docking assembly is completed, the locking nut can lock the position of the threaded rod and slider, ensuring the stability of the assembled air ducts. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A positioning device for a highway tunnel pipeline includes a lifting frame 1. Four mounting bolts 2 are threadedly connected to the lower surface of the lifting frame 1. A sliding groove is formed on the lower surface of the lifting frame 1. A positioning shaft 3 is fixedly connected to the inner wall of the sliding groove. Two sliders 4 are slidably connected to the inner wall of the sliding groove. A positioning component 5 is fixedly connected to the lower surface of each slider 4. The positioning component 5 includes a connecting block 501. A first positioning frame 502 and a second positioning frame 503 are fixedly connected to the lower surface of the connecting block 501. A rotating groove is formed on the lower surface of the first positioning frame 502. An arc-shaped base 505 is rotatably connected to the inner wall of the rotating groove through a rotating shaft 504. A threaded hole is formed on the front side of the arc-shaped base 505. A positioning groove is formed on the lower surface of the second positioning frame 503. Locking bolts 506 are threadedly connected to the opposite sides of the two second positioning frames 503 at positions corresponding to the positioning grooves.

[0023] The positioning groove corresponds to the position of the arc-shaped base 505. The locking bolt 506 is compatible with the threaded hole. A clamping mechanism is fixedly connected to the lower surface of the connecting block 501. The clamping mechanism includes a fixed frame 507. A strip groove is opened on the opposite sides of the two fixed frames 507. A movable block 508 is slidably connected to the inner wall of the fixed frame 507. A connecting rod 509 is fixedly connected to the lower surface of the movable block 508. An arc-shaped lower pressure plate 510 is fixedly connected to the bottom end of the connecting rod 509. The position of plate 510 corresponds to the position of arc-shaped base 505. The back sides of the two fixed frames 507 are fixedly connected to the U-shaped frame 511. The inner bottom wall of the U-shaped frame 511 is rotatably connected to the adjusting screw 512. The inner wall of the U-shaped frame 511 is slidably connected to the transmission block 513. The transmission block 513 is threadedly connected to the adjusting screw 512. The end of the transmission block 513 away from the inner wall of the U-shaped frame 511 extends through the strip groove into the interior of the fixed frame 507 and is fixedly connected to the movable block 508.

[0024] The hoisting frame 1 is fixedly installed at the top of the tunnel using four mounting bolts 2. When the air duct needs to be installed, the air duct is first lifted by the lifting equipment to the position between the first positioning frame 502 and the second positioning frame 503. The workers quickly close the two arc-shaped base supports 505, which can pre-support the air duct. The lifting equipment can be detached from the air duct before the air duct is fixed, so that the next air duct can be lifted. This greatly improves the installation efficiency of the air duct. By rotating the adjusting screw 512, the moving block 508 can be moved down through the transmission block 513. The moving block 508 then drives the arc-shaped pressure plate 510 to descend through the connecting rod 509 and cooperate with the arc-shaped base support 505 to clamp and position the air duct. This ensures the stability of the air duct between the first positioning frame 502 and the second positioning frame 503, and the overall efficiency is higher.

[0025] Example 2: The front of the hoisting frame 1 is provided with a strip hole, which is connected to the inside of the slide groove. The front of each of the two sliders 4 is fixedly connected with a threaded rod 6. The surface of each of the two threaded rods 6 is threaded with a locking nut 7. The front ends of the two threaded rods 6 pass through the strip hole and extend to the front of the hoisting frame 1, and the locking nut 7 is located at the position where the surface of the threaded rod 6 extends out of the front of the hoisting frame 1.

[0026] The two threaded rods 6 can drive the two sliders 4 to slide left and right on the surface of the positioning shaft 3, thereby facilitating the stable connection of the two sets of air ducts and making it easy to quickly complete the air duct connection and assembly operation, thus improving the efficiency of air duct connection and assembly. In addition, the two locking nuts 7 can lock the position of the threaded rods 6 and sliders 4, thereby ensuring the stability of the two sets of air ducts after connection and assembly.

[0027] Working Principle: First, the hoisting frame 1 is fixed to the top of the tunnel using four mounting bolts 2. When the duct needs to be installed, the duct is first lifted to a position below the hoisting frame 1 using a lifting device, and the duct is aligned between the first positioning frame 502 and the second positioning frame 503. The duct is then inserted into the first positioning frame 502 and the second positioning frame 503. At this time, the operator quickly closes the two arc-shaped base supports 505 and uses locking bolts 506 to lock the arc-shaped base supports 505 between the first positioning frame 502 and the second positioning frame 503, thereby supporting the position of the duct. At this time, the lifting device can proceed to lift the next duct without further support operations, thus greatly improving the installation efficiency of the duct. In addition, when the arc-shaped base supports 505 can support the duct, this... Rotating the two adjusting screws 512 causes the adjusting screws 512 to drive the transmission block 513 to move downward within the U-shaped frame 511. The transmission block 513 then drives the movable block 508 to move downward within the fixed frame 507. The movable block 508 can drive the arc-shaped pressure plate 510 to descend via the connecting rod 509 and cooperate with the arc-shaped base 505 to clamp and lock the air duct, ensuring the stability of the air duct at a high position. At the same time, the two sliders 4 can slide left and right on the surface of the positioning shaft 3. During the sliding process, they can drive the two sets of air ducts to move closer to each other, thus facilitating the connection of the air ducts. After the connection is completed, the two locking nuts 7 are moved backward on the threaded rod 6 to cooperate with the front of the lifting frame 1, locking the position of the threaded rod 6, and thus locking the position of the internal slider 4, ensuring the stability of the air duct after connection.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
