First, remove the small column, keep the arch mold 1 still, and push the arch mold rotating cylinder connected to the arch mold 2 upward to separate the connection between the arch mold 1 and the arch mold 2. Then operate the arch mold rotating cylinder connected to the arch mold 1 to lower the arch mold 1, and then operate the arch mold rotating cylinder connected to the arch mold 2 to lower the arch mold 2. The arch molds 1 and 2 form a folded state, and at the same time, the crossbeam is retracted to the shortest. In the retracted state, the distance between the arch mold 1 and the arch mold 2 is continuously adjusted to ensure the end face size of the main tunnel. In this state, the trolley can travel in the tunnel main section. During the process of entering the main tunnel, the centerline of the trolley is adjusted as a whole, and the arch mold rotating cylinder and the crossbeam are operated in reverse order according to the size of the main tunnel to open the arch mold 1 and the arch mold 2 until the requirements of the main tunnel construction are met.

At the same time, the driving mechanism drives the walking wheels to move to both sides, so that the trolley gantry is widened to the lining working position, loosen the connection between arch mold 1 and arch mold 2, and then operate the arch mold rotation cylinder to open arch mold 1 and arch mold 2, operate the side mold telescopic cylinder to open side mold 1 and side mold 2, and then install the small column between arch mold 1, arch mold 2 and the small longitudinal beam, and then tighten the arch molds on both sides with bolts. The lining state transformation of the emergency parking belt trolley is completed, and then the centerline adjustment is performed according to the conventional trolley operation to finally complete the lining operation. After the lining of this section of the emergency parking belt section is completed, it is transformed to the positive tunnel walking state in the reverse order of entering the emergency parking belt and can be transferred to the next working face.

[0012] Compared with the existing technology, the advantage of the present invention is that the trolley is installed outside the tunnel, reducing the installation risk, and adopts combined formwork and telescopic beams. When encountering an emergency parking strip during construction in the tunnel and needing to widen the formwork, the trolley can be quickly and autonomously transferred by changing the walking system spacing, widening the beam, and expanding the formwork.

[0017] In order to achieve the widening of the lining trolley, the crossbeam 23 is a telescopic sleeve structure, including an outer sleeve 231 and an inner sleeve 232.

8. A method for using a tunnel emergency parking strip lining trolley according to any one of claims 1 to 7, characterized in that: The following steps are involved: First, install the lining trolley outside the tunnel. During installation, the portal crossbeam is retracted first. In this state, the trolley can travel in the tunnel main section. First, remove the small column, keep the arch mold 1 still, and push the arch mold rotating cylinder connected to the arch mold 2 upward to separate the connection between the arch mold 1 and the arch mold 2. Then operate the arch mold rotating cylinder connected to the arch mold 1 to lower the arch mold 1, and then operate the arch mold rotating cylinder connected to the arch mold 2 to lower the arch mold 2. The arch molds 1 and 2 form a folded state, and at the same time, the crossbeam is retracted to the shortest. In the retracted state, the distance between the arch mold 1 and the arch mold 2 is continuously adjusted to ensure the end face size of the main tunnel. In this state, the trolley can travel in the tunnel main section. During the process of entering the main tunnel, the centerline of the trolley is adjusted as a whole, and the arch mold rotating cylinder and the crossbeam are operated in reverse order according to the size of the main tunnel to open the arch mold 1 and the arch mold 2 until the requirements of the main tunnel construction are met. The inner and outer sleeve connectors of the crossbeam are installed and tightened, and the connection between the top of the arch mold 1 and the top of the arch mold 2 is tightened. When reaching the section of the emergency parking strip, operate the saddle jack to extend, the vertical cylinder to retract, the cushion seat supports the trolley so that the travel system is suspended in the air, remove the positioning key, and manually rotate the travel system 90° outward; install the positioning key, operate the vertical cylinder to extend until the travel wheel contacts the support surface, operate the saddle jack to retract, and the cushion block is suspended in the air; Remove the inner and outer sleeve connectors, operate the width adjustment cylinder to extend, and realize the widening of the beam. At the same time, the driving mechanism drives the walking wheels to move to both sides, so that the trolley gantry is widened to the lining working position, install the inner and outer sleeve connectors and tighten them, loosen the connection between arch mold 1 and arch mold 2, and then operate the arch mold rotation cylinder to open arch mold 1 and arch mold 2, and then install the small column between arch mold 1, arch mold 2 and the small longitudinal beam, and then connect and tighten the arch molds on both sides with bolts. The lining state transformation of the emergency parking belt trolley is completed, and then the centerline adjustment is performed according to the conventional trolley operation to finally complete the lining operation. After the lining of this section of the emergency parking belt section is completed, it is transformed to the positive tunnel walking state in the reverse order of entering the emergency parking belt and can be transferred to the next working face.
