[0002] In tunnel construction, the tunnel face is the continuously advancing excavation face, representing the boundary between excavated and unexcavated rock strata. The verticality of the tunnel face has a significant impact on the accuracy of the tunnel excavation trajectory. To ensure the accuracy of the tunnel excavation path, it is necessary to control the verticality of the tunnel face. Current methods for measuring tunnel face verticality generally involve constructing a frame and then installing measuring instruments on it. This device is widely used in tunnel engineering fields such as railways, highways, urban subways, and water conservancy and hydropower.

[0003] However, as the tunnel excavation depth changes, the distance between the support frame and the tunnel face increases, leading to a decrease in the accuracy of the measurement of the tunnel face. This necessitates frequent disassembly and reassembly of the support frame to keep up with the progress of the tunnel face, which is time-consuming, labor-intensive, and requires a significant amount of time and manpower. Therefore, a tunnel face verticality detection device that is easy to disassemble and reassemble is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2-4 This utility model provides an embodiment of a conveniently assembled and disassembled tunnel face verticality detection device, comprising four fixed beams 1 that provide basic support. The bottom of each fixed beam 1 is fixedly connected to a socket 2, with a circular hole 3 on the outside of the socket 2. The top of each fixed beam 1 is fixedly connected to a strip 4 that can be inserted into the socket 2. The strip 4 has a circular groove 5 inside that accommodates an elastic component. A support plate 6, which can move flexibly within the groove, is slidably connected inside the groove 5. One end of the support plate 6 is fixedly connected to a spring 7 that provides elastic force, and the other end of the support plate 6 is fixedly connected to a locking tongue 8 that can pass through the circular hole 3 to achieve locking. Inserting a strip 4 from another device into the socket 2 of this device allows the two devices to be stacked to increase the height.

[0033] Reference Figure 2 , Figure 3 , Figure 5 Two adjacent fixed beams 1 are externally fixedly connected to assembly piece 1 9, and two other adjacent fixed beams 1 are externally fixedly connected to assembly piece 3 14. Assembly piece 1 9 is externally fixedly connected to two guide shafts 11. Assembly piece 2 10 is slidably connected to the outside of the shafts 11. Spring 2 12, which provides a restoring elastic force, is sleeved on the outside of the shafts 11. A latch 13 is fixedly connected to the end of the shafts 11 away from assembly piece 1 9. Assembly piece 3 14 is externally fixedly connected to two latch blocks 15. The latch blocks 15 have slots 16 that are adapted to the latches 13. When another latch block 15 on the device is abutted against the assembly piece 2 10 on the device, the spring 12 is squeezed, and the latch 13 on the device is inserted into the slot 16 in the latch block 15 on the other device, so that the device can be horizontally spliced.

[0034] Reference Figures 1-3 Two adjacent fixed beams 1 are fixedly connected with a reinforcing rod 2 18 to enhance lateral stability. Two fixed beams 1 on the same side are fixedly connected with a reinforcing rod 17 for longitudinal reinforcement. The two reinforcing rods 17 are fitted with buckles 19. A base plate 20 is fixedly connected to the buckles 19. Two support frames 21 for supporting the testing equipment are fixedly connected to the top of the base plate 20. Multiple screw holes 22 are opened inside the support frames 21. Bolts 23 for fixing the support platform 24 are threaded inside the screw holes 22. A support platform 24 for placing the testing instrument is set between the two support frames 21.

[0035] Reference Figures 2-4 The abutment plate 6 is slidably connected to the inner wall of the socket 2, and can slide smoothly within the socket 2. The locking tongue 8 is slidably connected to the inner wall of the round hole 3, and can be locked and unlocked through the round hole 3.

[0036] Reference Figures 2-4 The insertion port 2 abuts against the top of the fixed beam 1, ensuring a tight connection.

[0037] Reference Figures 2-4 The end of the spring 7 away from the abutment 6 is fixedly connected to the inner wall of the circular groove 5, providing stable elastic support for the abutment 6. The abutment 6 abuts against the inner wall of the circular groove 5, ensuring its stable sliding within the groove.

[0038] Reference Figure 2 , Figure 3 , Figure 5 One end of spring 12 is fixedly connected to the outside of assembly piece 10, and the other end of spring 12 is fixedly connected to the outside of assembly piece 9, providing elastic restoring force for assembly piece 10. The latch 13 is slidably connected to the inner wall of the slot 16 and abuts against the inner wall of the slot 16, ensuring a stable connection between the assembly pieces. The latch block 15 is slidably connected to the outside of assembly piece 10, facilitating the installation and disassembly of the two.

[0039] Reference Figures 1-3 Bolt 23 is threaded inside the support platform 24. Bolt 23 can firmly fix the support platform 24 to the support frame 21 and can adjust the height of the support platform 24 as needed.

[0040] Working principle: The device utilizes the insert 4 at the top of the fixed beam 1 to form an insertion and removal engagement with the insertion port 2 at the bottom of the fixed beam 1 of another device. When the insert 4 is inserted into the insertion port 2, the inner wall of the insertion port 2 presses against the locking tongue 8, causing the abutment plate 6 to compress the spring 7 and drive the locking tongue 8 to retract into the circular groove 5. After the insert 4 is fully inserted, the locking tongue 8 pops out under the elastic restoring force of the spring 7, passes through the circular hole 3 of the insertion port 2, and locks, thereby completing the longitudinal stacking of the two devices to increase the overall height. When disassembling, pressing the locking tongue 8 will release the lock. The locking block 15 of the other device is abutted against the assembly piece 10 of this device and pressure is applied. The assembly piece 10 slides along the circular shaft 11 and compresses the spring 12, so that the locking tongue 13 is aligned with the slot 16. At this time, the restoring force of the spring 12 pushes the assembly piece 10 to reset, driving the locking tongue 13 into the slot 16, realizing the lateral stable connection of the two devices. When disassembling, the opposite force is applied to make the locking tongue 13 disengage from the slot 16, and the spring 12 drives the assembly to reset. Regarding the support of the testing equipment, reinforcing rod 17 and reinforcing rod 28 enhance the structural stability of the fixed beam 1 frame from the longitudinal and transverse directions, respectively; buckle 19 fixes the base plate 20 to reinforcing rod 17, forming the load-bearing foundation of the testing equipment; by selecting screw holes 22 of different heights on the support frame 21 and fixing the support platform 24 with bolts 23, the placement height of the testing instrument can be flexibly adjusted to ensure that it maintains a suitable testing distance and angle with the tunnel face, providing a stable installation platform for verticality testing.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
