Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine (TBM) construction technology, specifically to a segment adaptive translation and transportation device and its construction method. Background Technology

[0002] Traditionally, tunnel segment transportation on the ground involves overhead cranes. When tunnel segments need to be hoisted down into the shaft, three on-site construction personnel must work together to complete the task. First, the personnel at the segment site and the crane operator work together to lift the segment. After the crane operator lifts the segment to directly above the shaft opening, the personnel at the bottom of the shaft direct the crane operator to lift the segment to the bottom of the shaft. During this process, personnel repeatedly install and dismantle the segment lifting equipment, making the process cumbersome and unpredictable, resulting in low efficiency in tunnel segment transportation.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention 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

[0004] To overcome the shortcomings of existing technologies, an adaptive translational transportation device for tunnel segments and its construction method are provided to solve the problem of low hoisting and transportation efficiency in the current ground tunnel segment transportation method that uses overhead cranes to transport tunnel segments into the well.

[0005] To achieve the above objectives, a segment adaptive translational transport device is provided, comprising:

[0006] A base is installed on one side of the wellhead of the ground well. The base is equipped with two guide rails arranged opposite each other. Sliding grooves are respectively opened on the opposite sides of the two guide rails, and the grooving direction of the sliding grooves is set towards the ground well.

[0007] Two outer support beams are respectively installed on opposite sides of the two guide rails in a liftable manner;

[0008] An inner bracket is disposed between the two guide rails, and rollers are rotatably mounted at opposite ends of the inner bracket, the rollers sliding in the groove;

[0009] A drive mechanism for pushing and pulling the inner bracket is mounted on the base;

[0010] An extension cable tray installed inside the wellhead includes two support frames and a support member. The support frames have opposing first and second ends. The first end of the support frame is rotatably mounted on the other side of the wellhead. The support member is fixed to one side of the wellhead. The two outer support beams rise to support the pipe segment, and the two outer support beams fall to allow the pipe segment to rest on the inner support frame. After the inner support frame supports the pipe segment, the two support frames are rotated so that the support member is supported on the second end of the two support frames and the two support frames are abutted in the grooves of the two guide rails. The drive mechanism pushes against the inner support frame so that the roller slides through the groove onto the support frame, thereby positioning the pipe segment above the wellhead.

[0011] Furthermore, the top of the support frame is flush with the bottom inner wall of the slide.

[0012] Furthermore, the top of the outer support beam is formed with an arc-shaped surface, the curvature of which is adapted to the curvature of the outer arc surface of the tube segment.

[0013] Furthermore, a lifting cylinder is vertically installed on the base, and the outer support beam is installed on the lifting cylinder.

[0014] Furthermore, the inner bracket includes two inner beams arranged opposite each other and a connecting beam connecting the two inner beams.

[0015] Furthermore, the driving mechanism is a push cylinder, and a reaction beam is connected between the ends of the two guide rails away from the wellhead. The push cylinder is connected between the connecting beam and the reaction beam.

[0016] Furthermore, multiple rollers are rotatably mounted on opposite sides of the two inner beams.

[0017] This invention provides a construction method for a segment adaptive translational transportation device, comprising the following steps:

[0018] The two outer support beams rise, making the outer support beams higher than the inner support frame;

[0019] The segment is hoisted and placed on the end of the outer support beam away from the wellhead of the shaft.

[0020] The inner bracket is positioned below the segment;

[0021] The two outer support beams are lowered so that the outer support beams are lower than the inner support frame, so that the segment rests on the inner support frame;

[0022] After the inner bracket supports the tube segment, the two support frames are rotated so that the support member is supported on the second end of the two support frames and the two support frames are connected to the slide groove of the two guide rails.

[0023] The drive mechanism pushes against the inner bracket, causing the roller to slide along the groove onto the support frame, so that the segment is positioned above the wellhead;

[0024] The segment grabbing mechanism installed at the wellhead grabs the segment;

[0025] Rotate the two support frames so that the support frames are removed from the area below the tube segment;

[0026] The segment grabbing mechanism lowers the segment into the ground wellbore.

[0027] The beneficial effects of this invention are that the tunnel segment adaptive translation transport equipment of this invention adopts a dual-track design, which can continuously and automatically transport tunnel segments with a high degree of automation, effectively reducing manpower and material resources. In addition, the dual tracks, together with the extended bridge installed in the wellhead of the ground shaft, enable the tunnel segments to be stably and reliably transferred to the wellhead of the ground shaft, and then, in conjunction with the subsequent tunnel segment grabbing mechanism, accurately transfer the tunnel segments from the ground to the underground tunnel, thereby improving the tunnel segment transfer efficiency and reducing labor costs.

[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Reference Figures 1 to 6 As shown, the present invention provides a segment adaptive translational transport device, including: a base 1, an outer support beam 2, an inner support frame 3, a drive mechanism 4, and an extension bridge 5.

[0038] In this embodiment, the base is a rectangular support plate. The support plate is arranged in a horizontal direction.

[0039] Specifically, a surface shaft is provided on the ground. The bottom of the surface shaft connects to the underground tunnel. A base 1 is installed on one side of the shaft opening 8 of the surface shaft. Two guide rails 11 are installed on the base 1, arranged opposite each other. Sliding grooves are respectively formed on opposite sides of the two guide rails 11. The grooves are oriented towards the surface shaft.

[0040] In this embodiment, the wellhead of the surface shaft is rectangular. Guide rails are installed along the width of the wellhead. The length of the tunnel segments is adapted to the width of the wellhead.

[0041] There are two outer support beams 2. The two outer support beams are arranged opposite each other. The two outer support beams are respectively located on opposite sides of the two guide rails. Specifically, the two outer support beams 2 are respectively installed on the base in a liftable manner.

[0042] The inner bracket 3 is positioned between the two guide rails 11. Rollers 33 are rotatably mounted at opposite ends of the inner bracket 3. The rollers 33 slide in the grooves.

[0043] When the outer support beam rises, its top is higher than the top of the inner support frame. When the outer support beam falls, its top is lower than the top of the inner support frame.

[0044] The drive mechanism 4 is mounted on the base 1. The drive mechanism 4 is used to push and pull the inner bracket 3 to move along the length of the guide rail's groove. The groove is set along the length of the guide rail. Therefore, the drive mechanism 4 drives the inner bracket to move towards or away from the wellhead of the surface well.

[0045] The extension cable tray 5 is installed inside the wellhead. Specifically, the extension cable tray 5 includes two support frames 51 and a support member 52. The support frames 51 have opposing first and second ends. The first end of the support frame 51 is rotatably mounted to the other side of the wellhead. The support member 52 is fixed to one side of the wellhead.

[0046] In this embodiment, the support frame is a steel structure beam. One end of the steel structure beam is hinged to the inner wall of the wellhead of the surface shaft. The support member is a wall-mounted steel beam. The wall-mounted steel beam is fixedly installed on the inner wall of the wellhead of the surface shaft. The support frame and the support member are arranged opposite to each other on two opposite inner walls of the wellhead.

[0047] During segment transfer, the outer support beams are raised, and a crane lifts the segment onto one end of the two outer support beams, so that the two outer support beams 2 support the segment 7. The inner bracket is moved to below one end of the outer support beams via a drive mechanism. After the two outer support beams 2 descend, the segment 7 rests on the inner bracket 3. (See reference...) Figure 6 As shown, after the inner bracket 3 supports the segment 7, the two support frames 51 are rotated so that the support member 52 supports the second end of the two support frames 51 and the two support frames 51 are connected to the sliding grooves of the two guide rails 11. This allows the support frame to be set outside the sliding groove of the guide rail and to connect with the sliding groove to form a channel extending into the wellhead of the ground shaft. The drive mechanism 4 pushes against the inner bracket 3, causing the roller 33 to slide through the sliding groove onto the support frame 51 (i.e., extending into the wellhead of the ground shaft), so that the segment 7 is set above the wellhead. This realizes the transfer process of accurately delivering the segment from the segment stacking site to the wellhead of the ground shaft, providing a guarantee for the subsequent accurate lowering of the segment into the tunnel.

[0048] In this embodiment, the top of the support frame 51 is flush with the bottom inner wall of the slide groove, thereby enabling the roller to achieve seamless connection between the slide groove and the support frame.

[0049] See Figure 5 As shown, before the tunnel lining segments are transferred toward the wellhead, the support frame is attached to the inner wall of the wellhead on the side furthest from the guide rail, and the support frame is positioned along the width of the wellhead. (See reference...) Figure 6 As shown, when the pipe segments are transported toward the wellhead, the support frame is rotated (the support frame rotates 90°, at which point it is positioned along the length of the wellhead), so that the support frame is positioned along the extension line of the chute along its length, allowing the pipe segments on the inner support beam to be smoothly positioned above the wellhead. A rotating mechanism, such as a hydraulic cylinder, is installed between the support frame and the inner wall of the wellhead to achieve automatic rotation of the support frame.

[0050] In a preferred embodiment, the top of the outer support beam 2 is formed with an arc-shaped surface. The curvature of the arc-shaped surface is adapted to the curvature of the outer arc surface of the segment 7. A lifting cylinder is vertically mounted on the base 1. The outer support beam 2 is mounted on the lifting cylinder 21.

[0051] In this embodiment, the inner bracket 3 includes two inner beams 31 and a connecting beam 32. The top surface of the inner beams is formed with an arc-shaped surface, the curvature of which matches the curvature of the outer arc surface of the segment. The two inner beams 31 are arranged opposite to each other. The connecting beam 32 connects the two inner beams 31.

[0052] In a preferred embodiment, the drive mechanism 4 is a pusher cylinder. A reaction beam 12 is connected between the ends of the two guide rails 11 furthest from the wellhead. The pusher cylinder is connected between the connecting beam 32 and the reaction beam 12.

[0053] In this embodiment, the inner beam, outer support beam, and guide rail grooves are arranged in the same direction. Multiple rollers 33 are rotatably mounted on the opposite sides of the two inner beams 31.

[0054] This invention provides a construction method for a segment adaptive translational transportation device, comprising the following steps:

[0055] S1: The two outer support beams 2 rise, making the outer support beams 2 higher than the inner support frame 3.

[0056] Specifically, the length of the outer support beam is adapted to the length of the guide rail. Both ends of the outer support beam are mounted on the base in a height-adjustable manner via lifting cylinders.

[0057] When transferring the tunnel segments to the wellhead of the surface well, the outer support beam is first lifted by the lifting cylinder so that the top of the outer support beam is higher than the top of the inner support frame.

[0058] S2: Hoist the segment 7 and place the segment 7 on the end of the outer support beam 2 away from the wellhead of the shaft.

[0059] In this embodiment, the tunnel segment is hoisted by a crane and placed on one end of the wellhead of the two outer support beams 2, away from the ground shaft.

[0060] S3: Place the inner bracket 3 below the segment 7.

[0061] The inner bracket is positioned at the end of the wellhead of the two outer support beams that is far from the ground, i.e., the inner bracket 3 is positioned directly below the segment 7.

[0062] S4: The two outer support beams 2 are lowered so that the outer support beams 2 are lower than the inner support frame 3, so that the segment 7 rests on the inner support frame 3.

[0063] S5: After the inner bracket 3 is supported on the tube segment 7, rotate the two support brackets 51 so that the support member 52 is supported on the second end of the two support brackets 51 and the two support brackets 51 are connected to the slide groove of the two guide rails 11.

[0064] S6: The drive mechanism 4 pushes against the inner bracket 3, causing the roller 33 to slide through the groove onto the support frame 51, so that the segment 7 is positioned above the wellhead.

[0065] S7: The segment grabbing mechanism 6, located at the wellhead, grabs the segment 7.

[0066] S8: Rotate the two support frames 51 so that the support frames 51 are removed from the area below the tube segment 7.

[0067] S9: The segment grabbing mechanism 6 lowers the segment 7 into the ground shaft.

[0068] The mechanism adopts a dual-track design, which can continuously and automatically transport tunnel segments.

[0069] 2) Use auxiliary support beams to achieve stability during segment transportation.

[0070] The tunnel segment adaptive translation transport equipment of the present invention adopts a dual-track design, which can continuously and automatically transport tunnel segments. It has a high degree of automation and can effectively reduce manpower and material resources. In addition, the dual tracks, together with the extended bridge installed in the wellhead of the ground shaft, enable the tunnel segments to be stably and reliably transferred to the wellhead of the ground shaft. Then, in conjunction with the subsequent tunnel segment grabbing mechanism, the tunnel segments are accurately transferred from the ground to the underground tunnel, which improves the tunnel segment transfer efficiency and reduces labor costs.
