Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment protection technology, specifically a shield tunnel segment transportation protection device. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction. They form the innermost barrier of the tunnel, bearing the responsibility of resisting soil pressure, groundwater pressure, and some special loads. TBM segments are the permanent lining structure of shield tunnels, and their quality directly affects the overall quality and safety of the tunnel, as well as its waterproofing and durability.

[0003] Existing patent CN216916811U discloses a protective structure for transporting tunnel segments, including a base plate. Two side plates are fixedly connected to the top of the base plate on both sides, and a tipping plate is rotatably connected between the side plates. The base plate has grooves on both sides of its top, one groove having a threaded rod movably connected between it, and the other groove having a limit rod fixedly connected between its two ends. A slider is movably connected between the limit rod and the threaded rod. This invention, through the tipping plate and base plate, ensures that the device continuously protects the tunnel segments during transport. The device limits the tunnel segments on three sides, and the tipping plate tilts the segments, making them less prone to movement during transport and thus safer. Furthermore, the arc-shaped plate and support rod provide support to the tunnel segments, preventing breakage due to insufficient support during transport.

[0004] However, existing patents have the following drawbacks:

[0005] Existing transport protection structures use tipping buckets and bottom plates to limit and protect shield tunnel segments. However, the size of the tipping buckets and bottom plates is fixed, which cannot adapt to the transport protection of shield tunnel segments of different sizes, resulting in poor practicality.

[0006] Existing transport protection structures lack shock absorption capabilities. When encountering bumpy road sections during the transport of tunnel segments, causing severe vibrations in the equipment, they cannot secure the position of the tunnel segments within the tipping bucket. This can easily lead to the tunnel segments swaying within the tipping bucket and causing damage. Furthermore, the integrity of the edges and corners of the tunnel segments cannot be guaranteed, reducing their practicality. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a device that can not only adapt to the transportation protection of shield tunnel segments of different sizes, but also buffer and reduce shock when encountering bumpy road sections during transportation to prevent the shield tunnel segments from shaking and causing damage.

[0008] To solve the above problems, the technical solution of this utility model is as follows: a shield tunnel segment transportation protection device, including a base plate, a baffle fixedly connected to the rear end of the top of the base plate, adjustment structures on both sides of the top of the base plate, a buffer structure on the opposite side of the adjustment structure, an L-shaped cover plate rotatably connected to the top of the baffle plate, an auxiliary support structure on the top of the base plate and the bottom of the L-shaped cover plate, a locking structure on the top of the front end of the adjustment structure, and a shield tunnel segment inside the buffer structure;

[0009] The adjustment structure includes a T-shaped slide groove, which is opened on the top of the base plate. A dual-axis motor is fixedly connected to the middle position of the T-shaped slide groove. Screws are fixedly connected to the output ends on both sides of the dual-axis motor. One end of the screw is rotatably connected to the inner wall of the T-shaped slide groove. A T-shaped slider is threaded onto the screw. A vertical plate is fixedly connected to the top of the T-shaped slider.

[0010] The buffer structure includes a groove on one side opposite to the vertical plate. A sliding rod is fixedly connected between the top and bottom of the front and rear ends of the inner wall of the groove. A movable plate is slidably connected to the sliding rod. A first buffer spring is fixedly sleeved on the sliding rod between the top of the movable plate and the top of the inner wall of the groove. A second buffer spring is fixedly sleeved on the sliding rod between the bottom of the movable plate and the bottom of the inner wall of the groove. A support plate is fixedly connected to one side opposite to the movable plate. A placement groove is provided on the top side opposite to the support plate.

[0011] Furthermore, the side of the baffle closest to the bottom plate is set as an inclined surface, and the side of the vertical plate closest to the baffle is set as an inclined surface to cooperate with the inclined surface of the baffle.

[0012] Furthermore, the top of the support plate and the inner wall of the placement groove are both inclined perpendicular to the slope of the baffle.

[0013] Furthermore, rectangular grooves are provided on both sides of the top of the L-shaped cover plate, and handles are rotatably connected in the rectangular grooves. A straight groove is provided on the side of the L-shaped cover plate away from the baffle.

[0014] Furthermore, the auxiliary support structure includes a fixed base, which is fixedly connected to the middle position of the top of the base plate. The fixed base has four contraction grooves at its top corners. A buffer spring three is fixedly connected to the bottom of the inner wall of each contraction groove. A support rod is slidably connected to the top of the contraction groove. A pressure plate one is fixedly connected to the bottom of the support rod. The bottom of the pressure plate one is fixedly connected to the top of the buffer spring three. An arc-shaped support plate one is fixedly connected to the top of the support rod. A sleeve is fixedly connected to the bottom of the L-shaped cover plate. A telescopic rod is slidably connected to the bottom of the sleeve. A pressure plate two is fixedly connected to the top of the telescopic rod. A buffer spring four is fixedly connected between the top of the inner wall of the sleeve and the top of the pressure plate two. An arc-shaped support plate two is fixedly connected to the bottom of the telescopic rod. Rubber pads are fixedly connected to the top of the arc-shaped support plate one and the bottom of the arc-shaped support plate two. Both the arc-shaped support plate one and the arc-shaped support plate two are inclined to match the placement groove.

[0015] Furthermore, the locking structure includes a limiting seat, which is fixedly connected to the top of the front end of the vertical plate. A rectangular slot is opened at the front end of the top of the vertical plate, and the front end of the L-shaped cover plate is engaged with the rectangular slot. A limiting rod is slidably connected inside the limiting seat, and a pressure plate three is fixedly connected to the limiting rod inside the limiting seat. A limiting spring is fixedly sleeved on the limiting rod between the pressure plate three and the inner wall of the limiting seat. A limiting groove is opened on the inner wall of the rectangular slot on the side away from the limiting seat.

[0016] The advantages of this invention compared to existing technologies are as follows:

[0017] This utility model is equipped with an adjustment structure, which drives the screw to rotate through a dual-axis motor, thereby causing the vertical plates to move closer or further apart, thus adapting to shield tunnel segments of various sizes and improving the applicability of the device;

[0018] This utility model incorporates a buffer structure and an auxiliary support structure. The inclined arrangement of the baffle, vertical plate, support plate, and placement groove allows the tunnel segment to be placed at an angle, preventing movement during transportation. When encountering bumpy road sections, the movable plate slides up and down on the sliding rod within the groove. The elastic action of buffer springs one and two buffer springs buffers and dampens the vibrations generated at both ends of the tunnel segment during bumps. Simultaneously, the tunnel segment is supported by the arc-shaped support plate one and resisted by the arc-shaped support plate two, keeping the tunnel segment in a clamped state. The elastic action of buffer springs three and four further enhances the buffer protection of the tunnel segment, improving the practicality of the device. Attached Figure Description

[0028] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1 to 7 As shown, a shield tunnel segment transportation protection device includes a base plate 1. A baffle 2 is fixedly connected to the rear end of the top of the base plate 1. Adjustment structures 3 are provided on both sides of the top of the base plate 1. The adjustment structure 3 includes a T-shaped slide 31. The T-shaped slide 31 is opened on the top of the base plate 1. A dual-axis motor 32 is fixedly connected to the middle position of the T-shaped slide 31. Screws 33 are fixedly connected to the output ends on both sides of the dual-axis motor 32. One end of the screw 33 is rotatably connected to the inner wall of the T-shaped slide 31. T-shaped sliders 34 are threadedly connected to the screws 33. A vertical plate 35 is fixedly connected to the top of the T-shaped sliders 34. In use, the dual-axis motor 32 is started to drive the screws 33 to rotate, thereby driving the vertical plates 35 to move closer or further apart, so as to adapt to shield tunnel segments 8 of various sizes and improve the applicability of the device.

[0031] A buffer structure 4 is provided on the opposite side of the adjusting structure 3. The buffer structure 4 includes a groove 41, which is located on the opposite side of the vertical plate 35. A slide rod 42 is fixedly connected between the top and bottom of the front and rear ends of the inner wall of the groove 41. A movable plate 43 is slidably connected to the slide rod 42. A buffer spring 44 is fixedly sleeved on the slide rod 42 between the top of the movable plate 43 and the top of the inner wall of the groove 41. A second buffer spring 45 is fixedly sleeved on the slide rod 42 between the bottom of the movable plate 43 and the bottom of the inner wall of the groove 41. A support plate 46 is fixedly connected to the opposite side. A placement groove 47 is opened on the opposite side of the top of the support plate 46. When encountering bumpy road sections during use, the movable plate 43 slides up and down on the slide rod 42 in the groove 41. At the same time, the movable plate 43 compresses the buffer spring 1 44 and the buffer spring 2 45. Through the elastic action of the buffer spring 1 44 and the buffer spring 2 45, the vibration generated at both ends of the shield tunnel segment 8 during bumps is buffered and damped, so as to avoid damage to the corners of the shield tunnel segment 8 due to collision caused by shaking.

[0032] The buffer structure 4 contains a shield tunnel segment 8. The side of the baffle 2 closest to the bottom plate 1 is set with an inclined slope. The side of the vertical plate 35 closest to the baffle 2 is set with an inclined slope to cooperate with the inclined slope of the baffle 2. The top of the support plate 46 and the inner wall of the placement groove 47 are both set with an inclined slope perpendicular to the inclined slope of the baffle 2. Through the inclined setting of the baffle 2, the vertical plate 35, the support plate 46 and the placement groove 47, the shield tunnel segment 8 can be placed at an inclined position during placement, so that the shield tunnel segment 8 is not easy to move during transportation, thus improving the stability during transportation.

[0033] An L-shaped cover plate 5 is rotatably connected to the top of the baffle 2. Rectangular grooves 51 are provided on both sides of the top of the L-shaped cover plate 5. A handle 52 is rotatably connected in the rectangular groove 51. A straight slot 53 is provided on the side of the L-shaped cover plate 5 away from the baffle 2. In use, the L-shaped cover plate 5 is opened by the handle 52, and the straight slot 53 facilitates the adjustment and fixing of the vertical plate 35 according to the different sizes of the shield tunnel segments 8.

[0034] An auxiliary support structure 6 is provided at the top of the base plate 1 and the bottom of the L-shaped cover plate 5. The auxiliary support structure 6 includes a fixed seat 61, which is fixedly connected to the middle position of the top of the base plate 1. The fixed seat 61 has a contraction groove 62 at the four corners of the top of the fixed seat 61. A buffer spring 63 is fixedly connected to the bottom of the inner wall of the contraction groove 62. A support rod 64 is slidably connected to the top of the contraction groove 62. A pressure plate 641 is fixedly connected to the bottom of the support rod 64. The bottom of the pressure plate 641 is fixedly connected to the top of the buffer spring 63. An arc-shaped support plate 65 is fixedly connected to the top of the support rod 64. A sleeve 66 is fixedly connected to the bottom of the L-shaped cover plate 5. A telescopic rod 67 is slidably connected to the bottom of the sleeve 66. A pressure plate 671 is fixedly connected to the top of the telescopic rod 67. A buffer spring 68 is fixedly connected between the top of the inner wall of the sleeve 66 and the top of the pressure plate 671. The bottom of the telescopic rod 67 is fixed. The device is connected to an arc-shaped support plate 2 69. Rubber pads are fixedly connected to the top of the arc-shaped support plate 1 65 and the bottom of the arc-shaped support plate 2 69. Both the arc-shaped support plate 1 65 and the arc-shaped support plate 2 69 are inclined to match the placement groove 47. When encountering bumpy road sections during use, the shield tunnel segment 8 moves up and down due to vibration, which drives the bottom arc-shaped support plate 1 65 to move up and down. This, in turn, drives the support rod 64 and the pressure plate 1 641 to compress or stretch the buffer spring 3 63. At the same time, it drives the top support arc-shaped support plate 2 69 to move up and down. The arc-shaped support plate 2 69 drives the telescopic rod 67 to slide in the sleeve 66, which in turn drives the pressure plate 2 671 to compress or stretch the buffer spring 4 68. Under the elastic action of the buffer spring 3 63 and the buffer spring 4 68, the shield tunnel segment 8 is more effectively buffered and protected, improving the practicality of the device.

[0035] The top of the front end of the adjusting structure 3 is provided with a locking structure 7. The locking structure 7 includes a limiting seat 71, which is fixedly connected to the top of the front end of the vertical plate 35. A rectangular slot 72 is opened at the front end of the top of the vertical plate 35. The front end of the L-shaped cover plate 5 is engaged with the rectangular slot 72. A limiting rod 73 is slidably connected inside the limiting seat 71. A pressure plate 74 is fixedly connected to the limiting rod 73 inside the limiting seat 71. The limiting rod is positioned between the pressure plate 74 and the inner wall of the limiting seat 71. A limiting spring 75 is fixedly sleeved on the 73. A limiting groove 76 is opened on the inner wall of the rectangular slot 72 away from the limiting seat 71. During use, the limiting rod 73 is pulled to disengage from the limiting groove 76. Then, the L-shaped cover plate 5 is snapped into the rectangular slot 72. After that, the limiting rod 73 is released. Under the elastic action of the limiting spring 75, the limiting rod 73 is driven to insert into the limiting groove 76, thereby achieving the tight restraint and limiting of the top of the shield tunnel segment 8 during transportation.

[0036] In practical use, firstly, the L-shaped cover plate 5 is opened. Then, depending on the size of the shield tunnel segment 8, the dual-axis motor 32 is started to drive the vertical plates 35 to move closer or further apart to accommodate shield tunnel segments 8 of various sizes. Next, the shield tunnel segment 8 is placed into the placement slot 47 on the support plate 46. By tilting the shield tunnel segment 8, it is less likely to move during transportation. Then, the limiting rod 73 is pulled to engage the L-shaped cover plate 5 into the rectangular slot 72. Afterward, the limiting rod 73 is released, and under the elastic action of the limiting spring 75, the limiting rod 73 is inserted into the limiting slot 76. At this time, the shield tunnel segment 8 is supported by the arc-shaped support plate 65 and resisted by the arc-shaped support plate 69, causing the shield tunnel segment... When the shield tunnel segment 8 is in a clamped state, the support plate 46 causes the shield tunnel segment 8 to sway up and down when it encounters a bumpy section. This causes the movable plate 43 to slide up and down on the slide rod 42 in the groove 41. Through the elastic action of the buffer spring 1 44 and the buffer spring 2 45, the vibration generated at both ends of the shield tunnel segment 8 during bumps is buffered and damped. At the same time, when the shield tunnel segment 8 sways up and down, it causes the arc-shaped support plate 1 65 at the bottom and the arc-shaped support plate 2 69 at the top to move up and down synchronously. Under the elastic action of the buffer spring 3 63 and the buffer spring 4 68, the collision force generated by the shield tunnel segment 8 during transportation is reduced, which can more effectively buffer and protect the shield tunnel segment 8 and improve the practicality of the device.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
