Description

Technical Field

[0001] This utility model relates to the field of shield tunnel construction technology, and in particular to a shield tunnel construction translation track device. Background Technology

[0002] Tunnel boring machines (TBMs) are widely used in tunnel construction. Based on their working principles, TBMs are mainly divided into earth pressure balance (EPB) TBMs and slurry balance (SPB) TBMs. TBM construction requires a transport convoy to transport materials such as tunnel segments and mortar. For EPB TBMs, the transport convoy also needs to include muck trucks to transport excavated soil out of the tunnel. Taking a slurry balance TBM as an example, the transport convoy typically consists of one mortar transport car, an electric locomotive, and two or three segment transport cars, arranged from the outside in.

[0003] In practical engineering, due to site limitations, the length of the starting shaft is often not designed to be large enough. When the transport train exits the tunnel and arrives at the starting shaft, the segment cars cannot be fully exposed, making it impossible to load segments onto them. Usually, to expose the rear segment cars from the tunnel, ground lifting equipment is needed to lift the preceding mortar transport cars off the track or to the ground. This method is inefficient and poses significant safety hazards. Another method uses a herringbone turnout to separate the mortar transport cars from the transport train. However, the transport train needs to frequently enter and exit the herringbone turnout, resulting in very low efficiency. Utility Model Content

[0004] This utility model provides a track-shifting device for shield tunnel construction, comprising:

[0005] The guide rails are provided in multiple ways, and the multiple guide rails are arranged parallel to each other.

[0006] A walking device is mounted on the guide rail, and the walking device moves along the direction of the guide rail via a driving device.

[0007] A support device is mounted on the traveling device, and a passing track assembly is supported on the support device. The movement of the traveling device drives the movement of the support device, causing the passing track assembly to translate.

[0008] Preferably, in this embodiment of the application, the walking device includes:

[0009] A movable wheel is mounted on the guide rail, and the movable wheel moves on the guide rail;

[0010] A rail clamping device is provided on both sides of the moving wheel, and the moving wheel is restricted to the guide rail by the rail clamping device.

[0011] Preferably, in this embodiment of the application, the rail clamping device includes:

[0012] Support members are provided on both sides of the movable wheel, and the support members are vertically arranged on the movable wheel;

[0013] A snap-fit ​​block is disposed on the support member. The snap-fit ​​block is disposed obliquely on the support member. Multiple snap-fit ​​blocks are disposed on both sides of the guide rail.

[0014] Preferably, in this embodiment of the application, a support platform is provided on the moving wheel, the support device is provided on the support platform, and the support device is fixedly connected to the support platform.

[0015] Preferably, in this embodiment of the application, the supporting device includes:

[0016] Multiple support blocks are provided, and each of the multiple support blocks is disposed on the support platform. The passing track assembly is supported on the support blocks.

[0017] The connector has two ends that are connected to the support block, and the connection direction of the connector is set along the direction of the guide rail.

[0018] Preferably, in this embodiment of the application, the passing track assembly is provided with two passing tracks, which are arranged in parallel to each other.

[0022] Preferably, in this embodiment of the application, the limiting device includes a detachable buffer pad, which is disposed on the contact end face between the limiting block and the walking device.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. By incorporating a rail-clamping device into the traveling mechanism, a double-limiting system is formed from both sides of the guide rail using support components and diagonally distributed clamping blocks. This effectively confines the moving wheels within the rail range, completely preventing the safety hazard of derailment due to vibration or offset during translation. Simultaneously, the limiting device at the end of the guide rail, through a combination of limiting blocks and buffer pads, achieves precise positioning of the passing rail components and provides buffer protection during docking and collisions, further enhancing the stability and safety of the device's operation.

[0025] 2. The two guide rails are installed perpendicular to the tunnel tracks. Combined with the movable passing rail assembly, they enable rapid and precise docking with the tunnel tracks on both sides, solving the problem of difficult passing during track transport in traditional tunnel construction. The drive unit propels the support device to move the passing rails horizontally. The entire docking process eliminates the need for repeated manual adjustments to the track positions, significantly reducing waiting time for passing during transport train formations and substantially improving the continuity of material transport and construction efficiency within the tunnel.

Detailed Implementation

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0035] like Figures 1 to 5 As shown in the figure, the present invention provides a shield tunnel construction translation track device, including a guide track 100, a walking device 200, a support device 300, and a passing track assembly 400. In this application, two guide tracks 100 are provided, and the two guide tracks 100 are arranged parallel to each other, so that the walking device 200 can move on the two guide tracks 100.

[0036] In this embodiment, two guide rails 100 are fixedly installed on the ground and are installed between the tunnel tracks on both sides. The installation positions of the two guide rails 100 are perpendicular to the installation directions of the two tunnel tracks, so that the passing track assembly 400 connects one side of the tunnel track or the other side of the tunnel track through the guide rails 100.

[0037] A traveling device 200 is installed on the guide rail 100. The traveling device 200 mainly includes moving wheels 210 and rail clamping devices 220. The moving wheels 210 are mounted on the guide rail 100 and can roll on the guide rail 100, thereby driving the entire traveling device 200 to move. The rail clamping devices 220 are located on both sides of the moving wheels 210. The main function of the rail clamping devices 220 is to restrict the moving wheels 210 on the guide rail 100 and prevent the traveling device 200 from derailing during movement. Specifically, the rail clamping device 220 includes a support member 221 and a locking block 222. The support member 221 is disposed on both sides of the moving wheel 210. The support member 221 and the moving wheel 210 move axially relative to each other, so that when the moving wheel 210 moves on the guide rail 100, the support member 221 moves horizontally along the guide rail 100 without rotating. The support member 221 is vertically disposed on the moving wheel 210. The locking block 222 is disposed on the support member 221 and is obliquely disposed on the support member 221. In this embodiment, multiple locking blocks 222 are provided, and the multiple locking blocks 222 are respectively disposed on both sides of the guide rail 100. When the moving wheel 210 moves on the guide rail 100, the locking block 222 contacts the side of the guide rail 100, thereby preventing the traveling device 200 from derailing.

[0038] In this embodiment, the support members 221 on both sides of the movable wheel 210 are a support plate structure. A horizontal plate is provided at the top of the support plate, so that the horizontal plate is positioned above the movable wheel 210. A support platform 230 is formed on the horizontal plate, and the support device 300 is installed on the support platform 230 to facilitate the fixed connection between the support device 300 and the support platform 230.

[0039] In this embodiment of the application, the support platform 230 is provided with support blocks 310 and connectors 320. Multiple support blocks 310 are provided and are evenly distributed on the support platform 230. Correspondingly, each moving wheel 210 is provided with a support block 310. The passing track assembly 400 is supported on the support block 310. The passing track assembly 400 is supported by the support block 310, so that the passing track assembly 400 can move smoothly.

[0040] The passing track 410 is effectively supported by multiple support blocks 310 so that the passing track 410 is placed horizontally above the guide track 100.

[0041] Both ends of the connector 320 are connected to the support blocks 310. The connector 320 is set along the direction of the guide rail 100. Multiple support blocks 310 are connected through the connector 320, thereby enhancing the stability of the support device 300.

[0042] In this embodiment, the connector 320 is connected to the support block 310, and the length of the connector 320 is equal to the width of the track, so that the passing track 410 above the support block 310 can dock with the tunnel track, making it convenient for vehicles to move from the tunnel track to the passing track 410.

[0043] In this embodiment of the application, the passing track assembly 400 includes two passing tracks 410, which are arranged in parallel to each other, and the distance between the two passing tracks 410 is the length of the connector 320.

[0044] Meanwhile, a drive device 500 is provided on one side of the support device 300. The output end of the drive device 500 is connected to the support block 310 on the support device 300. The drive device 500 drives the support device 300 to move along the direction of the guide rail 100, thereby driving the passing track assembly 400 along the direction of the guide rail 100. Figure 4 The translation is performed in the direction of the middle arrow. In this embodiment, the driving device 500 is preferably a hydraulic cylinder, which has the advantages of simple structure, reliable operation, and easy maintenance. Of course, in other embodiments, the driving device 500 can also be an electric push rod or a pneumatic cylinder, etc.

[0045] In this embodiment, a limiting device 110 is also provided on the guide rail 100. The limiting device 110 is a limiting block 111. When the passing track assembly 400 moves to the end position of the guide rail 100, the limiting block 111 limits the passing track assembly 400 to prevent it from falling off the guide rail 100. The limiting device 110 improves the safety and stability of the entire device. Simultaneously, when the passing track 410 abuts against the limiting block 111, the passing track 410 connects with the tunnel track, facilitating the movement of vehicles on the passing track 410 onto the tunnel track. Furthermore, the limiting device 110 also includes a detachable buffer block 112, which is located on the contact surface between the limiting block 111 and the traveling device 200. The buffer block 112 acts as a buffer when the passing track assembly 400 collides with the limiting device 110, protecting the device from damage.

[0046] Based on the above structural features, in this embodiment, the specific operation is as follows: In the initial state, the passing track 410 is connected to the tunnel track inside the tunnel. The mortar transport car at the front of the transport train fully enters the passing track 410 and then stops, disconnecting the mortar transport car from the locomotive. Then, the drive device 500 is activated, pushing the passing track 410 to move horizontally on the guide track 100 until the passing track 410 connects with the tunnel guide rail on the other side. The transport train then drives onto the passing track 410 until the segment car is fully exposed in the tunnel. After the transport train is loaded with materials, it enters the passing track 410 and moves it until it connects with the tunnel track. At this point, the mortar transport car can be connected to the locomotive to transport the materials into the tunnel. This achieves the function of this utility model.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
