Description

Technical Field

[0001] This invention relates to the field of sampling in tunnel segment production, and more specifically, to a test mold holder for sampling in the streamlined production of tunnel segments. Background Technology

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

[0003] There are currently no similar tools for sampling in the production of tunnel segments. In the production process of concrete tunnel segments, ordinary test molds are used to prepare samples manually and then cure them under the same conditions on the production line. The sampling of test blocks in the tunnel segment production process relies entirely on manual labor, which cannot efficiently achieve the sampling and curing of test blocks under the same conditions as required by the specifications. The operation is inconvenient. Therefore, a test mold holder for sampling in the production line of tunnel segments is proposed to solve this problem. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a test mold holder for sampling in the production line of pipe segments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A sample mold holder for sampling in the production line of tunnel segments includes a mold cart. A vibration frame is mounted on the top of the mold cart, and a tunnel segment mold is mounted on the top of the vibration frame. Two main beams are mounted on the vibration frame, located on the front and back of the tunnel segment mold, respectively. An upper sliding groove is formed on the top of each main beam, and a universal joint is slidably connected to the inner side of the upper sliding groove. A parallel beam is fixedly connected to the top of the universal joint, and a steering beam is movably connected to the top of the two parallel beams. Fixing clips are installed on the top of both the main beams and the parallel beams, and mold limiting clips arranged at equal intervals are fixedly connected to the top of the steering beam.

[0008] The vibration frame includes several elastic support columns, and an mounting frame is installed on the top between the elastic support columns. The segment mold is fixedly installed on the top of the mounting frame by bolts. A vibration motor is fixedly installed on the mounting frame. Two synchronous frames are fixedly installed on the top of the mounting frame. The two synchronous frames are located on the front and back of the segment mold, respectively. A slider is fixedly connected to the top of the synchronous frame, and the top of the slider is slidably connected to the main beam.

[0009] As a further description of the above technical solution:

[0010] The elastic support column includes a bottom column, a top column is slidably connected inside the bottom column, the top of the top column is fixedly connected to the mounting frame, a shock-absorbing spring is sleeved on the bottom column, the bottom of the bottom column and the shock-absorbing spring are both fixedly connected to the mold carriage, and the top of the shock-absorbing spring is fixedly connected to the mounting frame.

[0011] As a further description of the above technical solution:

[0012] A connecting block is fixedly connected to the bottom of the universal joint. The bottom of the connecting block extends into the interior of the upper sliding groove. The bottom of the connecting block is spherical and contacts the inner wall of the upper sliding groove.

[0013] As a further description of the above technical solution:

[0014] The synchronization frame includes a base frame, which is fixedly installed on the mounting frame. A top frame is inserted into the base frame, and a positioning pin is inserted through the base frame. One end of the positioning pin located inside the base frame is inserted into the top frame.

[0018] The slider includes a mounting block, on which a support block is threadedly connected. A sliding groove is provided at the bottom of the main beam, and the top of the support block is slidably connected to the inner wall of the sliding groove.

[0019] As a further description of the above technical solution:

[0020] The slider includes a mounting block, on which a support block is threadedly connected. A sliding groove is provided at the bottom of the main beam, and the top of the support block is slidably connected to the inner wall of the sliding groove.

[0021] Compared with the prior art, the advantages of this invention are:

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0030] Please see Figures 1-4In this invention, a test mold holder for sampling in the production line of pipe segments includes a mold cart 1. A vibration frame 10 is installed on the top of the mold cart 1. A pipe segment mold 2 is installed on the top of the vibration frame 10. Two main beams 3 are installed on the vibration frame 10. The two main beams 3 are located on the front and back of the pipe segment mold 2, respectively. An upper sliding groove 4 is opened on the top of the main beam 3. A universal shaft 5 is slidably connected to the inner side of the upper sliding groove 4. A parallel beam 6 is fixedly connected to the top of the universal shaft 5. A steering beam 7 is movably connected to the top of the two parallel beams 6. Fixing clips 8 are installed on the top of both the main beams 3 and the parallel beams 6. Mold limiting clips 9 arranged at equal intervals are fixedly connected to the top of the steering beam 7.

[0031] In this invention, the relative positions of the parallel beam 6 and the steering beam 7 with the segment mold 2 are adjusted by the two main beams 3 on the sliding vibration frame 10. Then, the two parallel beams 6 and the steering beam 7 are rotated to extend to the top of the segment mold 2, forming two supports. The bottom of the test mold is then aligned and connected with the mold limiting clip 9 on the steering beam 7, thereby installing the test mold on the top of the segment mold 2. When the inside of the segment mold 2 is poured, it can support the concrete. The fixing clip 8 can also provide a fixing effect. Then, the vibration frame 10 on the mold cart 1 drives the segment mold 2 to vibrate synchronously, thereby driving the test mold to vibrate. The defoaming process ensures the concrete within the mold is dense. Once the mold is full, subsequent concrete overflows. Simultaneously, the sliding connection between the universal joint 5 and the upper slide 4 between the main beam 3 and the parallel beam 6 allows the two parallel beams 6 to move synchronously through the mold, removing them from the pouring port of the segment mold 2. This reduces the impact on segment production. Currently, there are no similar tools on the market. During the production of concrete segments, this tool efficiently samples segments from the environment. Sampling of test blocks during segment production can be done without manual intervention, efficiently achieving the same-condition sampling and curing requirements specified in the standard. This fulfills the same-condition sampling objective required by the GB / T 22082-2017 standard for precast concrete lining segments, significantly reducing the workload of relevant personnel, shortening production time, greatly reducing labor, and significantly improving work efficiency.

[0032] Please see Figures 1-3 The vibration frame 10 includes several elastic support columns 101. A mounting frame 102 is installed on the top between the elastic support columns 101. The segment mold 2 is fixedly installed on the top of the mounting frame 102 by bolts. A vibration motor 103 is fixedly installed on the mounting frame 102. Two synchronous frames 104 are fixedly installed on the top of the mounting frame 102. The two synchronous frames 104 are located on the front and back of the segment mold 2, respectively. A slider 105 is fixedly connected to the top of the synchronous frame 104. The top of the slider 105 is slidably connected to the main beam 3.

[0033] In this invention, the energization of the vibration motor 103 can drive the mounting frame 102 to vibrate as a whole. The mounting frame 102 is mounted on the mold carriage 1 using the elastic support column 101. The vibration of the mounting frame 102 can drive the segment mold 2, the synchronous frame 104, and the main beam 3 on the slider 105 to vibrate. By controlling the synchronous vibration of the test mold, the sampling effect of the test mold can be improved while ensuring that the sample block is the same as the environmental raw material of the production segment, thus achieving the purpose of sampling under the same conditions.

[0034] Please see Figure 1 The elastic support column 101 includes a bottom column 1011, a top column 1012 is slidably connected inside the bottom column 1011, the top of the top column 1012 is fixedly connected to the mounting bracket 102, a shock-absorbing spring 1013 is sleeved on the bottom column 1011, the bottom of the bottom column 1011 and the bottom of the shock-absorbing spring 1013 are both fixedly connected to the mold carriage 1, and the top of the shock-absorbing spring 1013 is fixedly connected to the mounting bracket 102.

[0035] In this invention, the mounting frame 102 and the mold carriage 1 can be connected by the bottom column 1011 and the top column 1012, and then the mounting frame 102 and the mold carriage 1 are supported and damped by the shock-absorbing spring 1013 to reduce the impact of the mounting frame 102 on the mold carriage 1.

[0036] Please see Figure 1 , 2 4, wherein: the bottom of the universal joint 5 is fixedly connected to a connecting block 51, the bottom of the connecting block 51 extends into the interior of the upper sliding groove 4, the bottom of the connecting block 51 is spherical, and the bottom of the connecting block 51 contacts the inner wall of the upper sliding groove 4.

[0037] In this invention, the spherical connecting block 51 allows for both rotation and sliding within the upper sliding groove 4, enabling the parallel beam 6 mounted on the universal joint 5 to both slide and rotate simultaneously. This satisfies the user's needs to change the position of the parallel beam 6, facilitating the installation and adjustment of the mold, and improving user convenience.

[0038] Please see Figures 1-3 The synchronous frame 104 includes a base frame 1041, which is fixedly installed on the mounting frame 102. A top frame 1042 is inserted into the base frame 1041, and a positioning pin 1043 is inserted through the base frame 1041. One end of the positioning pin 1043 located inside the base frame 1041 is inserted into the top frame 1042.

[0039] In this invention, the mounting frame 102 and the slider 105 are connected by the base frame 1041 and the top frame 1042, thereby changing the distance between the mounting frame 102 and the main beam 3, controlling the installation height of the main beam 3, meeting the sampling requirements of different sized segment molds 2, and having a wider range of applications.

[0040] Please see Figures 1-3 The top of the top frame 1042 is provided with equally spaced screw holes 11, and a screw 12 is inserted through the slider 105. The top frame 1042 and the slider 105 are fixed together by the threaded connection between the bottom of the screw 12 and the screw hole 11.

[0041] In this invention, the installation position sliding on the top frame 1042 can be adjusted by matching the screw 12 with several screw holes 11, which facilitates adjustment and use, and also allows the main beam 3 to be disassembled and replaced, making the disassembly and assembly of the main beam 3 more convenient and easier to use.

[0042] Please see Figure 1 and Figure 2 The slider 105 includes a mounting block 1051, a support block 1052 is threadedly connected to the mounting block 1051, a sliding groove is provided at the bottom of the main beam 3, and the top of the support block 1052 is slidably connected to the inner wall of the sliding groove.

[0043] In this invention, by mounting block 1051 and support block 1052, rotating support block 1052 can change the height of support block 1052, thereby adjusting it according to the curvature of the main beam 3, which facilitates the docking and installation of the main beam 3 and support block 1052, allowing the synchronous frame 104 to be installed with trial mold brackets of various specifications, thus expanding its application range.

[0044] Please see Figure 2 A positioning rod 1053 is inserted between the mounting block 1051 and the support block 1052, and the top of the positioning rod 1053 extends to the top of the support block 1052.

[0045] In this invention, the positioning rod 1053 can restrict the threaded rotation between the mounting block 1051 and the support block 1052, thereby fixing the distance between the mounting block 1051 and the support block 1052 and improving structural stability.

[0046] Working principle: By adjusting the relative positions of the parallel beam 6 and the steering beam 7 with the segment mold 2 through the two main beams 3 on the sliding vibration frame 10, the two parallel beams 6 and the steering beam 7 are rotated to extend to the top of the segment mold 2, forming two supports. Then, the bottom of the test mold is aligned and connected with the mold limiting clip 9 on the steering beam 7, thereby installing the test mold on the top of the segment mold 2. When pouring concrete into the segment mold 2, it can support the concrete. The fixing clip 8 can provide a fixing effect. Then, the vibration frame 10 on the mold cart 1 drives the segment mold 2 to vibrate synchronously, thereby driving the test mold to vibrate. The defoaming process ensures the concrete within the mold is dense. Once the mold is full, subsequent concrete overflows. Simultaneously, the sliding connection between the universal joint 5 and the upper slide 4 between the main beam 3 and the parallel beam 6 allows the two parallel beams 6 to move synchronously through the mold, removing them from the pouring port of the segment mold 2. This reduces the impact on segment production. Currently, there are no similar tools on the market. During the production of concrete segments, this tool efficiently samples segments from the environment. Sampling of test blocks during segment production can be done without manual intervention, efficiently achieving the same-condition sampling and curing requirements specified in the standard. This fulfills the same-condition sampling objective required by the GB / T 22082-2017 standard for precast concrete lining segments, significantly reducing the workload of relevant personnel, shortening production time, greatly reducing labor, and significantly improving work efficiency.

[0047] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
