The safety of their tunnel structures is directly linked to the stable operation of this vital part of urban transportation. Tunnel lining construction, a core component of concealed engineering, must not only withstand the combined effects of ground pressure, groundwater corrosion, and train vibration loads, but also meet the durability requirements of a century-long service life.

The output ends of the two first hydraulic cylinders 105 are hinged to the slope walking mechanism.

[0024] The slope walking mechanism includes a connecting member 106, a displacement frame, a plurality of support legs 107, a plurality of second hydraulic cylinders 108 and two sets of abutment components. The connecting member 106 is hinged to the output end of the first hydraulic cylinder 105, the displacement frame is connected to the connecting member 106, the plurality of support legs 107 are fixedly connected to the displacement frame, the second hydraulic cylinder 108 is installed on the corresponding abutment component, the output end of the second hydraulic cylinder 108 is fixedly connected to the displacement frame, and the abutment component is slidably connected to the displacement frame.

[0025] The displacement frame includes a connecting plate 109 , a column 110 and two support plates 111 . The connecting plate 109 is connected to the connecting member 106 . The column 110 is fixedly connected to the connecting plate 109 , and both support plates 111 are fixedly connected to the column 110 .

[0026] With respect to this specific embodiment, when it is used, lining construction is carried out at the flat folding section of the entrance and exit (i.e., the turning area where the longitudinal section of the tunnel transitions from a flat slope to a large slope), and the slope walking mechanism is placed on the slope. When movement is required, the first hydraulic cylinder 105 is first started, and the first hydraulic cylinder 105 drives the displacement frame and the support legs 107 to move to the specified position. At this time, the second hydraulic cylinder 108 is extended, and then the abutting assembly near the connecting piece 106 is started to no longer abut the inner wall at the slope, and then the corresponding second hydraulic cylinder 108 is started. The second hydraulic cylinder 108 works to drive the abutting assembly near the connecting piece 106 to move After moving to the specified position, the supporting assembly close to the connecting member 106 is supported by the inner wall of the slope, and then the other group of the supporting assembly no longer supports the inner wall of the slope, and then the corresponding second hydraulic cylinder 108 is started, so that the supporting assembly away from the connecting member 106 moves to the specified position and supports the inner wall of the slope, and then the sliding member is started, and the sliding member drives the bracket 104 to move to the specified height, and the first hydraulic cylinder 105 is started. The first hydraulic cylinder 105 can pull the lining trolley body 101 when it works, thereby solving the technical problem of the inconvenience of the lining trolley in the secondary lining construction of the entrance and exit flat folding section (that is, the turning area where the longitudinal section of the tunnel transitions from a flat slope to a large slope) in the prior art.

The connecting rod 113 is fixedly connected to the two electric slides 112 . The two brackets 104 are both hinged to the connecting rod 113 .

[0028] According to this specific embodiment, by starting the two electric slides 112 , the two electric slides 112 drive the connecting rod 113 to move, and the connecting rod 113 further drives the bracket 104 to move up and down.

[0029] Furthermore, the supporting assembly includes a sleeve 114 and multiple groups of supporting units. The sleeve 114 has a through hole 115, and the through hole 115 is slidingly connected to the displacement frame. The multiple groups of supporting units are all arranged on the sleeve 114, and the second hydraulic cylinder 108 is installed on the sleeve 114.

[0030] According to this specific embodiment, when multiple groups of the supporting units are supported against the inner wall of the slope, when the first hydraulic cylinder 105 drives the displacement frame to move, the displacement frame slides on the inner wall of the through hole 115 of the sleeve 114, and the sleeve 114 does not move. When multiple groups of the supporting units are not supported against the inner wall of the slope, when the second hydraulic cylinder 108 moves, it drives the sleeve 114 to slide on the displacement frame.

[0032] According to this specific embodiment, the third hydraulic cylinder 116 drives the abutting plate 117 to abut against the inner wall of the slope for abutment and fixation.

[0033] Furthermore, the supporting plate 117 is arc-shaped.

[0034] According to this specific embodiment, the abutting plate 117 is more adapted to the inner wall of the slope, so that the contact surface is more closely fitted.

[0035] Furthermore, the second lining trolley of the large-slope flat-fold section of the subway light rail entrance and exit also includes a protrusion 119 and a plurality of fasteners 120. The connecting plate 109 has a groove 121. The protrusion 119 is slidingly connected to the groove 121, and the protrusion 119 is fixedly connected to the connecting member 106. One end of the fastener 120 is inserted into the groove 121 and tightened on the protrusion 119.

[0036] According to this specific embodiment, the connector 106 and the displacement frame can be assembled by placing the protrusion 119 in the groove 121, inserting one end of the fastener 120 into the groove 121, and tightening it on the protrusion 119, and vice versa, which facilitates disassembly.

[0037] Furthermore, the sleeve 114 is further provided with a plurality of obtuse-angle grooves 122 .

[0038] According to this specific embodiment, by providing the obtuse-angle groove 122 , material cost can be saved.

[0039] When using the second lining trolley for the steep flat-fold section of the entrance and exit of a subway or light rail of the present invention, lining construction is carried out at the flat-fold section of the entrance and exit (i.e., the turning area where the longitudinal section of the tunnel transitions from a flat slope to a steep slope) through the construction component 102 on the lining trolley body 101. The slope walking mechanism is placed on the slope. When movement is required, the first hydraulic cylinder 105 is first started, and the first hydraulic cylinder 105 drives the displacement frame and the support legs 107 to move to the specified position. At this time, the second hydraulic cylinder 108 is extended, and then the abutting component near the connecting piece 106 is started to no longer abut the inner wall at the slope, and then the corresponding second hydraulic cylinder 108 is started. The second hydraulic cylinder 108 works to drive the displacement frame and the support legs 107 near the connecting piece 106. The supporting assembly moves, and after moving to the specified position, the supporting assembly close to the connecting member 106 is pressed against the inner wall of the slope, and then the other group of the supporting assembly no longer presses against the inner wall of the slope, and then the corresponding second hydraulic cylinder 108 is started, so that the supporting assembly away from the connecting member 106 moves to the specified position and presses against the inner wall of the slope, and then the sliding member is started, and the sliding member drives the bracket 104 to move to the specified height, and the first hydraulic cylinder 105 is started. The first hydraulic cylinder 105 can pull the lining trolley body 101 when it works, thereby solving the technical problem of the inconvenience of the lining trolley in the secondary lining construction of the entrance and exit flat folding section (that is, the turning area where the longitudinal section of the tunnel transitions from a flat slope to a large slope) in the prior art.
