Description

Technical Field

[0001] This application relates to the field of shield tunneling auxiliary equipment technology, specifically to a device for suspending a movable air storage duct. Background Technology

[0002] During shield tunnel construction, the air storage duct of the tunnel boring machine (TBM) is typically fixed in the middle of the trailer. For tunnels with a central partition wall, this partition wall structure can interfere with the air storage duct, preventing its proper extension. Traditionally, the air storage duct is fixed in the middle of the TBM trailer, which limits TBM selection and excavation, and can even lead to insufficient airflow and poor ventilation within the tunnel, significantly impacting the safety of construction workers. Furthermore, current technology prevents the air storage duct from being moved; forced movement can easily cause bending and insufficient airflow, and also presents difficulties in installation and relocation when installing the corresponding tunnel ventilation duct.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "connection" and "linkage" in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0020] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all commercially available products.

[0021] To address the problem of existing immobile air storage ducts, this example discloses a movable air storage duct and a matching air duct suspension device, such as... Figure 1 As shown, the system includes a moving track 2 and a storage tank support that slides along the moving track 2. To prevent interference with the storage tank, the moving track 2 is laterally fixed to the shield tunnel trailer 1, allowing the storage tank support to slide the storage tank laterally. Preferably, the moving track 2 is made of two steel plates with dimensions of 5000mm in length, 100mm in width, and 40mm in height, welded to the shield tunnel trailer. Figure 4 , 6 As shown, to allow the air storage duct to slide on the moving track 2, the air storage duct support includes a rectangular frame made of steel profiles and wheels 3 fixed at the four corners of the bottom of the rectangular frame and matching the moving track. Preferably, the left and right sides of the rectangular frame are composed of symmetrically arranged U-shaped frames 4 with downward openings. Connecting beams 5 are fixed to the bottom of the front and rear side arms of the two U-shaped frames 4. The connecting beams 5 are 200*150mm H-shaped steel with a length of 2870mm. To fix the air storage duct within the rectangular frame, electric lifting devices 6 are symmetrically arranged on both sides of the rectangular frame. Specifically, the electric lifting devices 6 are electric hoists, which can fix the air storage duct within the rectangular frame by tightening the support frame 19 of the air storage duct. Specifically, the air storage duct support is moved laterally on the moving track 2 by manual pushing. To limit the air storage duct support to its position on the moving track 2 after lateral movement, as shown... Figure 2As shown, anti-detachment devices are provided at both ends of the corresponding air storage cylinder support on the moving track 2. These devices include pin seats 7 fixed to the side of the moving track 2, pin blocks 8 fixed to the rectangular frame corresponding to the pin seats 7, and pin shafts 9 that engage with the pin blocks 8 and lock with the pin seats 7. This ensures that the air storage cylinder support is locked in place by the anti-detachment device after it has moved into position, making it safe and effective.

[0022] To facilitate the installation of tunnel ventilation ducts that correspond to each other, and to reduce the occurrence of bending and insufficient airflow in the ventilation ducts, such as... Figure 3 As shown, several ventilation duct supports 10 are spaced apart along the extension direction of the tunnel ventilation duct on the shield trailer. Each support includes a vertical rod 11, an arc-shaped rod fixed to the top of the vertical rod 11 with the same curvature as the tunnel ventilation duct, a fixing buckle 12 fixed to the arc-shaped rod for constraining the tunnel ventilation duct, and a fixing block 13 fixed to the bottom of the vertical rod 11. The ventilation duct supports are detachably fixed to the corresponding positions of the tunnel ventilation duct by bolting four bolts 14 through the fixing block 13 to the shield trailer, facilitating the connection of the tunnel ventilation duct to accommodate air storage ducts in different locations. Figure 1 , 5 As shown, in order to suspend the tunnel ventilation duct on the ventilation duct support 10, steel wire ropes 15 are threaded through the fixing buckles 12 of several ventilation duct supports 10, and the tunnel ventilation duct is provided with corresponding buckles 20 for the steel wire ropes to pass through, which facilitates installation and ensures stable connection. Taking a φ1500mm tunnel ventilation duct as an example, the vertical rod 11 is a long rod with a φ50mm diameter and a length of 2000mm. The arc-shaped rod includes a connecting rod 15 (635mm long) fixed at the top of the vertical rod 11 at a 150° angle with the vertical rod 11, and a connecting rod 27 (691mm long) fixed at the corresponding end of the connecting rod 16 at a 137° angle with the connecting rod 16. The connecting rods 16 and 27 are welded to the vertical rod 11 to form an arc-shaped rod that fits in close with the tunnel ventilation duct, ensuring the stability of the tunnel ventilation duct fixation.

[0023] To facilitate the connection of tunnel ventilation ducts by workers, such as Figure 1 As shown, an arc-shaped connecting guardrail 18 is symmetrically provided on the shield trailer 1 at the end corresponding to the tunnel ventilation duct and fits against the surface of the tunnel ventilation duct. The arc-shaped connecting guardrail 18 is welded and fixed with the installation position of the tunnel ventilation duct and plays a protective role in the connection between multiple tunnel ventilation ducts.
