[0002] Lining trolley, referred to as trolley, is mainly used for concrete pouring of tunnels, diversion tunnels, and secondary linings. The trolley is mainly composed of a gantry and a template. The gantry is mainly load-bearing, and the template is designed according to the shape of the tunnel carriageway; it has the advantages of automatic walking, hydraulic automatic positioning and demoulding (can achieve up, down, left, and right movement).

[0003] During the lining construction of railway tunnels, there is no special device to reinforce the diagonal support of the lining trolley on the invert filling surface; the existing method is to drill holes and embed reinforcement on the invert filling surface, which destroys the concrete structure and flatness of the invert filling, and the use of embedded reinforcement causes unnecessary material waste and a certain degree of safety hazards.

[0004] Therefore, there is an urgent need for a drilling-free support and reinforcement device for a lining trolley. Utility Model Content

[0008] To further optimize the technical solution, the length of the first supporting side is greater than the length of the second supporting side.

[0009] To further optimize the technical solution, the first supporting edge and the second supporting edge are both formed by welding I-beams.

[0010] To further optimize the technical solution, a contact increasing mechanism for increasing the contact area with the supporting diagonal rod is provided on the left side of the supporting steel plate; the contact increasing mechanism includes a hinged seat arranged on the supporting steel plate, and a force-bearing plate is hinged on the hinged seat for contacting the end of the supporting diagonal rod and capable of adjusting the angle up and down; supporting bolts for fixing the position of the force-bearing plate are provided on the supporting steel plate, and the supporting bolts are respectively located on the upper and lower sides of the hinged seat.

[0011] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is as follows.

[0012] The utility model provides a punch-free support reinforcement device for a lining trolley, which fixes the lining trolley support diagonal rod by a reinforcement frame erected at a right angle on the inverted arch filling surface, replacing the original reinforcement method of punching holes on the inverted arch filling surface.
