Single-track railway lining trolley
Single-track railway lining trolley is a special equipment that must be used in the secondary lining of single-track railway tunnel construction. It is used for lining construction of the inner wall of the tunnel. It has the functions of vertical mold and demoulding function, high surface finish of lining and fast lining speed.

Single-track railway trolley working principle
The outer contour of the Single-track railway lining trolley is consistent with the inner contour surface of the tunnel lining. The lining of the tunnel is realized by sealing the excavated silo surface at both ends of the stencil and forming a closed annular silo with the excavated surface, and then pouring concrete. The power of the trolley is motor driven, rail-type walking system; the template action mode is the hydraulic cylinder piston movement mode, and the adjustment of the vertical acceptance mode and the template center deviation is completed; after the trolley is established, the template needs to be passed through the lead screw. The frame is integrated to withstand the construction loads during concrete casting.
Single-track railway lining trolley design features
- Single-track railway lining trolley template All curved flanges and strengthened arcs are made of 14mm steel plate and 10mm panel, ensuring smooth and flawless joints.
- The anti-displacement screw is installed between the side mold beam and the door frame to ensure the stability of the template trolley while walking, and prevent the template from being misaligned before and after lining.
- The design of the grouting hole structure adopts the screw cap operation method, so that the concrete after pouring does not leave any defects, and the operation is simple and convenient.
- The trolley travels with motor drive, the motor power is 2*5.5KW, the operation is simple, and the action is flexible and reliable.
- The vertical mold is hydraulically driven, which can greatly reduce the labor intensity of construction and make the realization of various movements of the template simple and fast.
- The working window and the template are adjusted by bolts, which are easy to open and close, and the gap is small.
- All electrical components comply with national standards and are safe and reliable.
- All hydraulic components and hydraulic pipelines conform to national standards, and there will be no leakage or blockage.
- The lifting cylinder adopts mechanical self-locking, which is more reliable than the hydraulic lock. It can prevent the trolley from sinking and cause the template to be connected to the wrong platform. The lining quality is good.
- The supporting jack adopts double-headed spiral, which has good supporting effect and large supporting force.
11. The sill bracing adopts the channel steel beam to buckle, and the cross section is box-shaped structure, and the force effect is good
