Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel construction equipment, specifically, it relates to an auxiliary support device for pipelines of a lining trolley. Background Technology

[0002] While excavating with an open-face TBM, simultaneous concrete lining is typically carried out, transforming tunnel excavation and lining from single-process operations to parallel, continuous operations. This improves tunnel construction safety and overall efficiency. During simultaneous lining construction, to ensure the passage of the lining trolley and the installation of the lining, the water pipes need to be temporarily removed from the lifting points at the tunnel ceiling. To provide traction for the pipes after the lifting points are removed, the pipes are usually suspended inside the trolley. However, the internal formwork structure of the trolley has limited strength, and the heavy pipes pose a risk of pulling and deforming the trolley formwork, affecting the structural stability of the simultaneous lining trolley.

[0003] Application No. CN202520094591.7 discloses a water pipe support device based on an open-type TBM synchronous lining trolley. This device utilizes vertically moving idlers to achieve effective contact support for water pipes of varying heights during synchronous lining operations. The power unit can adjust the position of the crossbeam as needed based on the current pipe height, thereby adjusting the height of the idlers. Furthermore, the side grooves effectively limit and guide the movement of the crossbeam, ensuring the stability of the crossbeam and idlers during lifting and lowering. While this device has some practical benefits, during the lining trolley's movement, the relative movement of the pipes and idlers poses a risk of the pipes slipping off the ends of the idlers. Also, the support position of the idlers on the pipes is concentrated in one area, and the stability of the pipe support needs improvement.

[0004] In view of this, this utility model is proposed. Utility Model Content

Side supports are installed between a set of support mounting seats 5 of the extension support seat 3. A main support roller 6 is provided between the support roller 7 and the support mounting seat 5 of the main support frame 1. A side limit baffle 9 is provided on both the main support roller 6 and the side support roller 7. The main support frames 1 are fixedly connected by a support connecting plate 22. A support mating seat 13 is provided below the main support frame 1. A side bracket 15 is provided on the support mating seat 13. A support threaded rod 16 is provided on the side bracket 15. A support top seat 19 is provided at the upper end of the support threaded rod 16. The support top seat 19 is used to effectively support the extension support seat 3.

[0021] The support mating seat 13 is provided with a support mating groove 14, and the lower end of the side bracket 15 is provided with a mating slide. The mating slide is slidably installed in the support mating groove 14. The two sides of the support mating groove 14 are provided with adjustment and fixing holes for locking the position of the side bracket 15 with mating screws.

[0022] The side bracket 15 has an L-shaped structure. The support threaded rod 16 is connected to the side bracket 15 by a thread. The upper end of the support threaded rod 16 is rotatably connected to the support top seat 19. A locking nut 17 is provided on the support threaded rod 16 below the side bracket 15. An adjustment end is provided on the lower end of the support threaded rod 16 to facilitate rotational adjustment of the support threaded rod 16.

[0023] Both the main support roller 6 and the side support roller 7 are provided with roller grooves 8. Multiple limiting and fixing holes 10 are arranged on both sides of the roller groove 8. A side limiting baffle 9 is slidably connected and installed in the roller groove 8. The side limiting baffle 9 is used to effectively shield and protect the pipeline.

[0024] Locking screws are provided on the outer side of the extension support base 3. The support mating base 13 is fixedly installed at both ends of the main support base 12. The top surface of the main support base 12 and the support connecting plate 22 bracket are provided with a power component 18, which is used to drive the support connecting plate 22 to lift and adjust.

[0025] Auxiliary support rods 20 are symmetrically arranged on both sides of the power component 18. The auxiliary support rods 20 are hollow structures, and telescopic support rods 21 are slidably connected and installed inside the hollow structures.

[0027] The working principle of this utility model is as follows: Example 1: The power component 18 can adjust the height of the support connecting plate 22 and the main support frame 1 as a whole. When adjusting the height of the main support frame 1 through the power component 18, the locking screw on the outside of the auxiliary support rod 20 is loosened to release the locking limit of the telescopic support rod 21, so that the telescopic support rod 21 can slide along the auxiliary support rod 20. After adjusting to a suitable height position, the locking screw on the outside of the auxiliary support rod 20 is tightened to lock the adjustment position of the telescopic support rod 21, thereby reducing the pressure on the power component 18. The distance between the side support roller 7 and the main support roller 6 can be adjusted. Loosen the locking screw on the outside of the main support frame 1 to release the locking limit of the extension telescopic rod 2, so that the extension telescopic rod 2 can slide along the main support frame 1. After adjusting to a suitable distance position, tighten the locking screw on the outside of the main support frame 1 to lock the adjusted position of the extension telescopic rod 2. Then adjust the position of the side bracket 15 on the support mating seat 13 so that the position of the support top seat 19 corresponds to the position of the extension support seat 3. Lock the position of the side bracket 15. Adjust by rotating the adjusting end of the support threaded rod 16. The support threaded rod 16 is adjusted to rise and fall relative to the side bracket 15 so that the support top seat 19 can effectively support the extension support seat 3 and improve the structural stability of the side support roller 7. Example 2: A telescopic support plate 4 is provided below both the side support roller 7 and the main support roller 6. The relative position of the telescopic support plate 4 and the extension support seat 3 can be adjusted as needed, so that the height of the side support roller 7 and the main support roller 6 can be adjusted independently. Side limiting baffles 9 are provided on the side support roller 7 and the main support roller 6 to effectively block and limit the pipeline, prevent the pipeline from slipping off the end of the support roller, and improve the support stability of the device. This utility model is equipped with a main support roller 6 and two side support rollers 7. The main support roller 6 and the side support rollers 7 can be adjusted in height as a whole or individually. The distance between the side support rollers 7 and the main support roller 6 can also be adjusted as needed, which can meet diverse support needs and facilitate storage. A side bracket 15 is provided below the side support rollers 7. The side bracket 15 is equipped with a support threaded rod 16, a support top seat 19 and a locking nut 17, which are used to provide effective auxiliary support for the extension support seat 3.
