Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] In the embodiments of this application, such as Figures 1 to 10 As shown, the secondary lining formwork trolley includes a formwork assembly 1 and a supporting body 2; wherein, A support drive assembly 5 is provided on the side wall of the support body 2; The cross-sectional shape of the template assembly 1 matches the cross-sectional shape of the tunnel wall to be lined. The template assembly 1 is fitted onto the support body 2, and the actuating end of the support drive component 5 contacts the inner wall of the template assembly 1. (See attached image) Figure 1 The template assembly 1 is driven by the support drive component 5 to slide along the length of the support body 2 until both ends of the template assembly 1 are aligned with the two ends of the support body 2. The support body 2 and the support drive component 5 jointly support the template assembly 1.

[0032] When secondary lining of a tunnel is required, the workers can send the support body 2 and the formwork assembly 1 from the secondary lining formwork trolley to the tunnel entrance, and use the hoisting equipment (truck crane) to directly hoist the formwork assembly 1 to one end of the support body 2. Then, the operators, in coordination with the hoisting equipment, adjust the relative positions of the template assembly 1 and the support body 2 so that the axis of the template assembly 1 coincides with or is nearly coincident with the axis of the support body 2. The hoisting equipment moves the template assembly 1 closer to the support body 2, and one end of the template assembly 1 is fitted onto the support body 2, and the moving end of the support drive component 5 contacts the inner wall of the template assembly 1. Subsequently, with the help of the support drive component 5, the template assembly 1 is driven to slide along the length of the support body 2 until the template assembly 1 is completely fitted onto the support body 2. At this time, the support body 2 and the support drive component 5 can jointly support the template assembly 1 so that the template assembly 1 is stably erected on the support body 2. After the installation of the template assembly 1 is completed, the secondary lining template trolley can be sent to the tunnel for secondary lining construction.

[0033] The entire installation process is relatively simple and convenient, and the installation of template assembly 1 can be completed easily and quickly, reducing the impact of the installation of template assembly 1 on the efficiency of tunnel secondary lining construction.

[0034] In some embodiments, the secondary lining formwork trolley also includes a pouring system 4, see [link to documentation]. Figure 3 , Figure 4 and Figure 10 ;in, The aforementioned template assembly 1 is provided with multiple pouring ports 113; The casting system 4 includes a box 41 and a casting pipeline 42; The box body 41 is mounted on the aforementioned support body 2, and a pouring pump is installed inside the box body 41; One end of the pouring pipe 42 is connected to the discharge end of the pouring pump, and the other end of the pouring pipe 42 extends to the pouring port 113. During the secondary lining construction, the workers can start the pouring pump to extract the concrete from the box 41 and send it to the gap between the formwork assembly 1 and the tunnel wall; after the concrete solidifies, the secondary lining construction is completed. The secondary lining construction process does not require concrete pump trucks to enter the tunnel for pouring, thereby reducing the occupation of tunnel space and avoiding interference with other operations, thus making the secondary lining construction smoother.

[0035] In some embodiments, the template assembly 1 described above includes a plurality of lining templates 11, see [reference]. Figure 1 , Figure 2 and Figure 3 ;in, T-slots 111 and T-protrusions 112 are respectively provided on both sides of the lining template 11. The length direction of the T-slots 111 and T-protrusions 112 is parallel to the axis of the template assembly 1. Multiple lining templates 11 are spliced ​​in an arc shape in sequence through the cooperation of T-slots 111 and T-protrusions 112 to make the connection between two adjacent lining templates 11 more stable. When it is necessary to install or disassemble the lining template 11, the support drive assembly 5 can be used to drive the lining template 11 to be installed or disassembled, so that the lining template 11 to be installed or disassembled slides along the length direction of the support body 2 until the two ends of the lining template 11 to be installed or disassembled are aligned with the adjacent lining template 11, or completely separated; during this process, the cooperation of the T-slot 111 and the T-protrusion 112 has a certain guiding effect, so as to make the installation and disassembly of the lining template 11 more convenient.

[0036] Preferably, the support body 2 is provided with a clamping assembly 26 for fixing the lining template 11, see [reference]. Figure 2 The clamping component 26 is used to fix the lining template 11 that does not need to be disassembled, so that the support drive component 5 can accurately drive the lining template 11 that needs to be disassembled to be disassembled, making the disassembly of the lining template 11 more convenient.

[0037] The clamping assembly 26 mentioned above includes a telescopic rod and a U-shaped buckle. One end of the telescopic rod is rotatably mounted on the support body 2, and the rotation axis of the telescopic rod is parallel to the central axis of the support body 2. The U-shaped buckle is mounted on the other end of the telescopic rod, and the opening of the U-shaped buckle faces the support body 2. When it is necessary to dismantle one of the lining templates 11 (the lining template 11 to be dismantled), the operator can rotate the telescopic rod to the lining template 11 adjacent to the lining template 11 to be dismantled, and fasten the U-shaped buckle to the lining template 11 adjacent to the lining template 11 to be dismantled, so as to limit its movement. Then, the support drive assembly 5 is activated, and the moving end of the support drive assembly 5 drives the lining template 11 to be disassembled to slide along the length direction of the support body 2, so that the lining template 11 to be disassembled is separated from the adjacent lining template 11, thus completing the disassembly of the lining template 11 to be disassembled.

[0038] In some embodiments, the aforementioned support drive assembly 5 includes a telescopic cylinder 51, a drive motor 52, and a gear 53. (See also...) Figure 3 ;in, One end of the telescopic cylinder 51 is mounted on the side wall of the support body 2; the drive motor 52 is mounted on the other end of the telescopic cylinder 51, and the gear 53 is coaxially mounted on the shaft of the drive motor 52. The inner sidewall of the lining template 11 is provided with a rack 12, the length direction of the rack 12 is parallel to the length direction of the support body 2, and the gear 53 meshes with the rack 12; by controlling the operation of the drive motor 52, the lining template 11 can be moved along the length direction of the support body 2 through the cooperation of the gear 53 and the rack 12, so as to realize the installation or disassembly of the lining template 11.

[0039] In some embodiments, the aforementioned support body 2 includes a plurality of gantry frames 21, see [reference]. Figure 5 and Figure 7 ;in, The gantry 21 is a "gate"-shaped support frame. Multiple gantry 21s are arranged sequentially along one direction. Adjacent gantry 21s are connected and fixed by connecting rods 22. In this embodiment, the connecting rods 22 include "X"-shaped connecting rods and "I"-shaped connecting rods. The four ends of the "X"-shaped connecting rods are respectively connected to two adjacent gantry 21s, and the two ends of the "I"-shaped connecting rods are respectively connected to two adjacent gantry 21s. The ends of both the "X"-shaped connecting rods and the "I"-shaped connecting rods are welded and fixed to the gantry 21 to improve the stability of the support body 2 structure. The support drive assembly 5 is installed on the side wall of the gantry 21. The top of the gantry 21 and the support drive assembly 5 can jointly support the formwork assembly 1 so that the formwork assembly 1 can overcome the flow pressure from the uncured concrete and the lateral load of the soil during the secondary lining construction, making the structure of the secondary lining formwork trolley more stable.

[0040] In some embodiments, the aforementioned support body 2 further includes a support beam 23, see [reference]. Figure 5 and Figure 8 ;in, The support beam 23 is mounted on multiple gantry frames 21, and the length direction of the support beam 23 is parallel to the arrangement direction of the multiple gantry frames 21. Multiple top support rods 25 are provided on the top of the support beam 23. The template assembly 1 is mounted on the top support rod 25 at the position corresponding to the support beam 23. In this embodiment, the top support rod 25 is a hydraulic cylinder, and its length can be adjusted according to the requirements to adapt to the secondary lining construction of tunnels with different diameters. Of course, in order to adapt to the secondary lining construction of tunnels with different diameters, the template assembly 1 also needs to be replaced according to the diameter of the tunnel.

[0041] In some embodiments, the aforementioned support body 2 further includes a work ladder 24, see [link to relevant documentation]. Figure 1 and Figure 5 ; The working ladder 24 is installed on one of the gantry 21; in this embodiment, the working ladder 24 is installed on one of the gantry 21 at the end of the corresponding support body 2, which makes it convenient for workers to climb to the top of the support body 2 to maintain the secondary lining template trolley. The top platform of the working ladder 24 is equipped with a control console. The aforementioned pouring system 4, top support rod 25 and support drive assembly 5 are all electrically connected to the control console. The control console can control the opening and closing of the pouring system 4, the extension and retraction of the top support rod 25, the extension and retraction of the telescopic cylinder 51 in the support drive assembly 5, and the adjustment of the rotation direction of the drive motor 52, thereby making the use of the secondary lining formwork trolley more convenient.

[0042] In some embodiments, the secondary lining template trolley further includes a movable support frame 3. Figure 5 , Figure 6 and Figure 9 ;in, The main support 2 is detachably mounted on the mobile support frame 3, which can move in the tunnel to better facilitate the transfer of the secondary lining template trolley and improve the construction efficiency of the tunnel secondary lining.

[0043] Specifically, the aforementioned movable support frame 3 includes a bottom fixed beam 31 and a traveling device 32; wherein, There are two bottom fixing beams 31, and both bottom fixing beams 31 are parallel to the central axis of the support body 2; in the support body 2, the two legs of the gantry 21 are respectively supported on the two bottom fixing beams 31. There are four walking devices 32, which are respectively set at both ends of the two bottom fixed beams 31. By controlling the movement of the walking devices 32, the movement of the secondary lining formwork trolley can be realized, making the use of the secondary lining formwork trolley more convenient.

[0044] It is worth noting that the walking device 32 includes a walking motor and rollers. The walking motor is mounted on the bottom fixed beam 31 and is electrically connected to the aforementioned control console. The rollers are coaxially mounted on the shaft of the walking motor. By controlling the movement of the walking motor through the control console, the secondary lining template trolley can be driven to move.

[0045] In some embodiments, the aforementioned movable support frame 3 further includes a lifting device 33, see [link to relevant documentation]. Figure 1 , Figure 6 and Figure 9 ;in, The lifting device 33 is mounted on the bottom fixed beam 31. The actuating end of the lifting device 33 is connected to the supporting body 2. The lifting device 33 is electrically connected to the aforementioned control console. The lifting device 33 can be controlled by the control console to change its length. That is, the lifting device 33 can be extended and retracted by the control console to adjust the height of the supporting body 2, so as to better adapt to the construction of secondary lining in tunnels of different diameters.

[0046] Preferably, there are four lifting devices 33. The four lifting devices 33 are respectively installed at both ends of the two bottom fixed beams 31. The lifting ends of the four lifting devices 33 are respectively connected to the four corners of the support body 2 to realize individual adjustment of the height of the four corners. In the case of complex terrain (uneven ground) such as tunnels, the height of both ends of the support body 2 can be adjusted independently by the four lifting devices 33 to quickly correct the tilt caused by the uneven ground and improve the stability of the secondary lining template trolley operation process.
