Description

Technical Field

[0001] This utility model relates to the field of tunnel segment misalignment correction technology, specifically to an auxiliary device for correcting misalignment of tunnel segments in shield tunnels. Background Technology

[0002] A tunnel segment is a basic unit of precast tunnel lining ring made primarily of reinforced concrete, also known as a reinforced concrete tunnel segment. Segments are connected by specialized bolts to form unit rings, which are then assembled ring by ring to form a tunnel. It is mainly used in tunnel projects using the shield tunneling method, such as those for rail transit, highways, railways, hydraulic engineering, power, and municipal works, where it directly bears the responsibility of resisting soil pressure. Because it directly resists the soil pressure, the lower segments will settle and become misaligned. This means that the bolt holes on two adjacent segments cannot be aligned, so special bolts cannot be used to connect the two adjacent segments together. Therefore, it is necessary to use a correction auxiliary component to correct the misalignment. The existing alignment auxiliary components cannot adjust the distance between the upright and the segment during use. When aligning, the distance between the upright and the segment is too close, which increases the operator's waist bending. When lifting the upright upwards for alignment, there is a phenomenon that the force cannot be exerted. Therefore, improvements are needed. Therefore, it is necessary to invent an auxiliary device for correcting misalignment of shield tunnel segments. Summary of the Invention

[0003] Therefore, this utility model provides an auxiliary device for correcting misalignment of shield tunnel segments to solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for correcting misalignment of shield tunnel segments, comprising a base block, a groove on the base block, a pin movably embedded in the base block, a vertical rod fixedly connected to one side of the pin, the vertical rod being hollow, and a handle being movably inserted inside the vertical rod; The pole is fixedly fitted with a connecting block, the bottom of the connecting block is provided with a pull block, a protruding rod is fixedly connected to one side of the pull block, and an adjustable connecting component is provided between the pull block and the connecting block.

[0005] Preferably, the connecting assembly includes pin two and pin three, pin two being movably embedded in the connecting block, and pin three being movably embedded in the pull block.

[0006] Preferably, both ends of the second pin are fixedly connected to connecting rods, and both connecting rods have multiple through holes arranged in a straight line.

[0007] Preferably, both ends of the pin three are fixedly connected to sleeves, and each of the two sleeves has a through hole two. The two connecting rods are respectively movably inserted into the two sleeves and are respectively connected to the two sleeves by bolts.

[0008] Preferably, the top of the upright has a through hole, the top of the connecting block has a pressure rod embedded therein, and the pressure rod and the connecting block are connected by threads.

[0009] Preferably, the bottom end of the pressure rod passes through the through hole and contacts the grip rod.

[0010] Preferably, the outer sleeve of the convex rod is provided with multiple annular protrusions.

[0011] Preferably, the cross-section of each of the annular protrusions is T-shaped.

[0012] The beneficial effects of this utility model are: by setting a connecting component between the connecting block and the pull block, the distance between the connecting block and the pull block can be adjusted during use, thereby adjusting the distance between the upright and the pipe segment.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] See attached document Figure 1 -Appendix Figure 7 The present invention provides an auxiliary device for correcting misalignment of shield tunnel segments, including a base block 1, a groove 2 on the base block 1, a pin 3 movably embedded on the base block 1, a vertical rod 4 fixedly connected to one side of the pin 3, the vertical rod 4 being hollow, and a handle 5 movably inserted inside the vertical rod 4. The pole 4 is externally fixedly fitted with a connecting block 6. The bottom of the connecting block 6 is provided with a pull block 7. A protruding rod 8 is fixedly connected to one side of the pull block 7. An adjustable connecting component is provided between the pull block 7 and the connecting block 6. Combined with appendix Figure 5-7 This means that the bolt holes 19 on two adjacent pipe segments 17 cannot be aligned, making it impossible to connect the two adjacent pipe segments 17 together using special bolts. Therefore, this device is needed for correction. In this embodiment, when using the device, place the base block 1 in the slot 18 on the right pipe segment 17, then hold the pull block 7 and insert the protruding rod 8 into the bolt hole 19 on the left pipe segment 17. At the same time, the pull block 7 will be located in the slot 18 on the left pipe segment 17. Then, hold the handle 5 and pull the handle 5 and the upright 4 upwards. This allows the upright 4 and the handle 5 to rotate around the pin 3. Then, under the action of the connecting block 6 and the connecting assembly, the pull block 7 and the protruding rod 8 can move upwards, thereby pulling the supported pipe segment 17 upwards until the contact parts of the two pipe segments 17 are aligned. After alignment, fill the bottom of the left pipe segment 17 with concrete mortar. This achieves the correction of the pipe segment 17. After the correction is completed, the bolt holes 19 on the two pipe segments 17 can be aligned, and then the two pipe segments 17 can be connected together using special bolts. A connecting component is set between the connecting block 6 and the pull block 7. When in use, the distance between the connecting block 6 and the pull block 7 can be adjusted, thereby adjusting the distance between the upright 4 and the segment 17. This can prevent the upright 4 from getting too close to the segment 17, so that the operator does not need to bend over excessively when correcting the deviation, and will not experience the phenomenon of being unable to exert force. In this embodiment, the connecting assembly includes a second pin 9 and a third pin 10. The second pin 9 is movably embedded in the connecting block 6, and the third pin 10 is movably embedded in the pull block 7. The front and rear ends of the second pin 9 are fixedly connected to connecting rods 11. Both connecting rods 11 have multiple through holes 12 arranged in a straight line. The front and rear ends of the third pin 10 are fixedly connected to sleeves 13. Both sleeves 13 have through holes 2 14. The two connecting rods 11 are movably inserted into the two sleeves 13 respectively, and are respectively connected to the two sleeves 13 by bolts. It should be noted that since the two connecting rods 11 are connected to the two sleeves 13 by bolts, when it is necessary to adjust the distance between the upright 4 and the tube segment 17, simply loosen the bolts, then pull the upright 4 upward to move the two connecting rods 11 upward. This allows the length of the connecting rods 11 and the sleeves 13 to be adjusted. After the length adjustment is completed, the other through holes 12 on the connecting rod 11 and the through holes 14 on the sleeve 13 will coincide. Then, the connecting rods 11 and the sleeves 13 can be connected together with bolts to complete the length adjustment. This can prevent the operator from not being able to apply force when correcting the deviation. In this embodiment, a through hole is provided at the top of the upright 4, and a pressure rod 15 is embedded at the top of the connecting block 6. The pressure rod 15 is connected to the connecting block 6 by a thread, and the bottom end of the pressure rod 15 passes through the through hole and contacts the handle 5. It should be noted that since the grip 5 can move within the upright 4, the length of the lever arm can be adjusted when pulling upwards, making it easier to correct deviations. Since the pressure rod 15 and the connecting block 6 are connected by threads, similar to the threaded connection of a bolt and nut, the pressure rod 15 can be turned to make it contact the grip 5 after adjusting the length of the grip 5 and the upright 4. This can compress the grip 5 and prevent it from moving freely within the upright 4. In this embodiment, the protruding rod 8 is externally fixedly sleeved with multiple annular protrusions 16, and the cross-section of the multiple annular protrusions 16 is T-shaped. It should be noted that multiple annular protrusions 16 are provided on the protruding rod 8, and the cross-section of the annular protrusions 16 is all T-shaped. This can prevent the protruding rod 8 from falling out of the bolt hole 19 on the tube segment 17 during the correction.

[0019] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
