[0028] For details, please refer to Figure 1 , Figure 2 and Figure 5The connecting mechanism 11 includes a main pull rod 22 arranged between the two movable columns 5, and internal threaded holes 23 are respectively opened at both ends of the main pull rod 22. The inner cavities of the two internal threaded holes 23 are respectively threadedly sleeved with first external threaded columns 24, and the ends of the two first external threaded columns 24 are respectively fixedly connected with auxiliary pull rods 25. One ends of the two auxiliary pull rods 25 extend to the outside of the main pull rod 22 and are fixedly connected with connecting columns 26. The ends of the two connecting columns 26 are respectively fixedly connected with second external threaded columns 27, and the two second external threaded columns 27 are respectively threadedly sleeved into the inner cavities of the two internal threaded tubes 10.

[0029] In this embodiment, the distance between the two connecting columns 26 is adjusted by the threaded fit between the first external thread column 24 and the internal thread hole 23, thereby adjusting the distance between the two supporting mechanisms.

[0030] For details, please refer to Figures 1 to 4 The fixing mechanism 14 includes a fixing cover 15 fixedly sleeved on the outside of the moving column 5 or the supporting column 3, the inner wall of the fixing cover 15 is fixedly connected with a spring 16, the end of the spring 16 is fixedly connected with a pull block 17, one end of the pull block 17 is fixedly connected with a round head pin 19, the end of the round head pin 19 is movably sleeved to the inner cavity of the socket 12, and the other end of the pull block 17 is fixedly connected with a handle 18.

[0031] In this embodiment, the handle 18 is used to pull the pull block 17 and the round head pin 19 so that the round head pin 19 can be separated from the inner cavity of the socket 12 when the support mechanism is disassembled. In addition, during installation, the elastic force of the spring 16 is used to drive the round head pin 19 to be inserted into the socket 12 on the upper socket 8 and the lower socket 2.

[0033] In this embodiment, the position between the movable column 5 and the support column 3 is limited by the movable cooperation between the limiting sliding rod 21 and the support column 3, so as to prevent the movable column 5 from rotating relative to the support column 3.

[0035] In this embodiment, the stability of the support column 3 inserted into the lower socket 2 is ensured by the contact between the side of the lower socket 2 and the inner wall of the lower slot 13. In addition, the stability of the support frame 9 installed on the top of the movable column 5 is ensured by the fit between the inner wall of the upper slot 7 and the side of the upper socket 8.

[0036] For details, please refer to Figures 2 to 4 , the inner diameter of the socket 12 is equal to the outer diameter of the round head pin 19.

[0037] In this embodiment, the stability of the round head pin 19 inserted into the insertion hole 12 is ensured.

[0038] For details, please refer to Figure 1 A plurality of screws 20 are sleeved on the base 1 .

[0039] In this embodiment, the base 1 is fixed to the ground of the tunnel by means of screws 20 .

[0040] Working principle: When in use, first install multiple bases 1 on the ground of the tunnel through screws 20, and put the support column 3 on the lower socket 2 on the top surface of each base 1, so that the lower socket 2 is inserted into the lower slot 13 on the bottom surface of the support column 3. In the process of inserting the lower socket 2 into the lower slot 13, the top of the lower socket 2 first squeezes the round head pin 19 to move outward, and the spring 16 is stretched at this time. When the bottom surface of the support column 3 and the top surface of the base 1 are in contact, the round head pin 19 and the socket 12 on the side of the lower socket 2 are aligned, and the restoring elastic force of the spring 16 is used to drive the round head pin 19 to be inserted into the socket 12, so as to fix the lower socket 2 and the support column 3. Then, the support frame 9 is placed above the two movable columns 5 at the top of the base 1, and the upper socket 8 at the bottom of the support frame 9 is inserted into the upper slot 7. At this time, the upper socket 8 pushes other round head pins 19 during the downward movement, so that the round head pin 19 is inserted into the socket 12 on the side of the upper socket 8 , thereby fixing the support frame 9 and the moving column 5, and then placing the connecting mechanism 11 between the two opposite internal threaded tubes 10 of the two moving columns 5, rotating the connecting column 26 to drive the auxiliary pull rod 25, the first external threaded column 24 and the second external threaded column 27 to rotate, and utilizing the threaded cooperation between the first external threaded column 24 and the internal threaded hole 23 to drive the two connecting columns 26 to move away from each other, when the second external threaded column 27 and the internal threaded tube 10 are in contact, the second external threaded column 27 is screwed into the inner cavity of the internal threaded tube 10, thereby installing the main pull rod 22, the first external threaded column 24, the auxiliary pull rod 25, the connecting column 26 and the second external threaded column 27 between the two internal threaded tubes 10, thereby pulling the two adjacent support mechanisms to ensure the stability of the support structure, and finally starting the hydraulic rod 4 to drive the moving column 5 and the support frame 9 to move upward, so that the top of the support frame 9 and the top of the tunnel are against each other, thereby supporting the tunnel.

[0041] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
