Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

If the specific posture changes, the directional indications will also change accordingly. In addition, if there are descriptions such as "first, second", "S1, S2", "step one, step two", etc. involved in the embodiments of the present utility model, then such descriptions are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features or indicating the execution order of the method, etc. Those skilled in the art can understand that all those that do not violate the key points of the utility model under the technical concept of the utility model should be included in the protection scope of the present utility model.

[0034] The present utility model provides an intelligent adaptive variable-section TBM synchronous lining trolley, referring to Figure 1 , including: a gantry assembly 1, a variable-diameter telescopic assembly 2, a lining formwork assembly 3, and an extension assembly 4;

[0035] The lining formwork assembly 3 includes a number of arc-shaped formworks connected in sequence and is detachably arranged on the periphery of the gantry assembly 1;

[0036] The variable-diameter telescopic assembly 2 is arranged between the gantry assembly 1 and the lining formwork assembly 3, and its telescopic movement drives the diameter of the lining formwork assembly 3 to increase or decrease;

[0037] The extension assembly 4 is used to be arranged at the notch of the lining formwork assembly 3 when the diameter of the lining formwork assembly 3 increases.

[0038] In this embodiment, an intelligent adaptive variable-section TBM synchronous lining trolley of the present utility model is provided. During use, first, a plurality of arc-shaped templates are sequentially connected and arranged around the gantry assembly 1 to support the inner side of the tunnel; at this time, the gantry assembly serves as an internal support structure and is the framework of the entire lining trolley, used to install and support other components and reserve the required space for other components; the lining formwork assembly thereon is arranged on the inner side of the tunnel to form an arched arc surface to fix the concrete between the tunnel and the lining formwork assembly for tunnel construction operations. When the inner diameter of the tunnel changes, for example, when the inner diameter increases, the variable-diameter telescopic assembly 2 is extended, which can drive the lining formwork assembly to move to the side away from the gantry assembly, causing the overall deformation of the lining formwork assembly. The distance between the plurality of arc-shaped templates that make up the lining formwork assembly increases, and the overall corresponding perimeter of the lining formwork assembly increases synchronously. At this time, it no longer encloses a closed section designed in advance with the tracks laid in advance at the bottom of the tunnel, such as the bottom invert and side walls. It is necessary to add a lengthening assembly at the notch of the lining formwork assembly to make up for the notch to form a closed section and then carry out construction operations; more specifically, when the inner diameter decreases, the variable-diameter telescopic assembly 2 is shortened, which can drive the lining formwork assembly to move to the side close to the gantry assembly, causing the overall deformation of the lining formwork assembly. The distance between the plurality of arc-shaped templates that make up the lining formwork assembly decreases, and the overall corresponding perimeter of the lining formwork assembly decreases synchronously. At this time, the notch will also continuously shrink, and it is necessary to remove the lengthening assembly to avoid hindering the overall reduction of the inner diameter of the lining formwork assembly and then carry out construction operations.

[0039] It can be seen that the rapid variable-section TBM synchronous lining trolley provided by the present utility model can quickly and adaptively adjust the diameter of the lining trolley according to the actual situation of the tunnel under construction by setting a lining formwork assembly composed of a plurality of arc-shaped templates, a variable-diameter telescopic assembly, and a lengthening assembly, so as to expand its scope of use. Compared with the traditional method, when encountering a variable-diameter situation, the method of re-designing and manufacturing a new synchronous lining trolley and transporting it to the construction site will greatly improve the construction efficiency and reduce the waste of manpower, financial resources, and time. It should be noted that the key of this application is to provide a rapid variable-section TBM synchronous lining trolley that adaptively adjusts the diameter of the synchronous lining trolley from the mechanical structure. The specific control process, action time, and driving path of each component's movement, lifting, and action can be realized by manual or programmable logic devices such as PLC, which will not be elaborated here.

[0040] Preferably, referring to Figure 1 and Figure 2 , the gantry assembly 1 includes: a gantry body 11, a platform 12, and a platform telescopic member 13;

[0041] The gantry body 11 is arranged on the track at the bottom of the tunnel;

[0042] The stand 12 is detachably arranged on the door frame body 11;

[0043] The platform telescopic member 13 is arranged between the platform and the portal frame body.

[0044] In this embodiment, the gantry assembly includes a gantry body and a platform, and a platform telescopic member is added between the two. When the diameter of the rapid variable section TBM synchronous lining trolley increases or decreases, the gantry body located below remains stationary, and the platform telescopic member arranged between the gantry body and the platform is extended or retracted, so that the platform located above rises or falls accordingly, ensuring that the corresponding center of the lining formwork assembly rises or falls, so that the overall skeleton of the gantry assembly adapts to the change in the diameter of the rapid variable section TBM synchronous lining trolley, so as to better support and carry other components, and at the same time adapt to the change in the force angle caused by the change in the diameter of the lining formwork assembly, and improve the force condition of the entire gantry assembly.

[0045] More preferably, the structure of the stand is bilaterally symmetrical, and the stand 12 includes: a plurality of longitudinal support rods 121 and transverse support rods 122;

[0046] The lower end of the longitudinal support rod is detachably connected to the portal frame body, and the upper end is connected to the inner side of the lining formwork assembly;

[0047] A transverse support rod is arranged between two longitudinal support rods;

[0048] Preferably, the stand 11 further comprises an oblique support rod 123, which is arranged on the outside of the outermost longitudinal support rod and tilted upward toward the lining formwork assembly; preferably, the variable diameter telescopic assembly is arranged on the oblique support rod.

[0049] In this embodiment, a preferred embodiment of the gantry assembly is further given. The gantry is stably supported on the gantry body by criss-crossing support rods, and at the same time, strong support is provided for the lining formwork assembly supported thereon, so as to improve the structural strength of the rapid variable section TBM synchronous lining trolley; and oblique support rods are further provided to install a variable diameter telescopic assembly, so that the variable diameter telescopic assembly can more strongly support the lining formwork assembly, and during the extension or shortening process of the lining formwork assembly, the lining formwork assembly can be obliquely propped open, and the inner diameter of the lining formwork assembly can be changed more intuitively and conveniently, so as to achieve a better variable diameter effect of the rapid variable section TBM synchronous lining trolley.

[0050] More preferably, refer to Figure 1 and Figure 2 The gantry assembly 1 also includes a first adjusting member 14, which is detachably installed between the gantry body 11 and the stand 12, and the distance adjusted by the first adjusting member 14 is adapted to the change in the diameter of the variable section.

[0051] In this embodiment, after the bench telescopic member is fully extended or retracted, due to the large weight of the bench itself, if the bench telescopic member continues to bear the gravity of the bench for a long time at this time, the telescopic performance of the bench telescopic member will be damaged, and even the bench telescopic member may be damaged, resulting in the inoperability of the rapid variable-section TBM synchronous lining trolley. Therefore, a first adjusting member is added to the gantry assembly. When the bench telescopic member extends, the first adjusting member is installed to bear the gravity of the bench, which can improve the service life of the rapid variable-section TBM synchronous lining trolley; at the same time, the distance adjusted by the first adjusting member is adapted to the change amount of the tunnel variable-section diameter, and the change amount of the bench telescopic member is no longer used to adapt to the change amount of the tunnel variable-section diameter, which can improve the accuracy of the diameter change. Optionally, the first adjusting member is a set of combined pads with different thicknesses, or a screw adjustment member that realizes distance adjustment by a screw and a thread pair, or a scissor arm distance adjustment member that realizes distance adjustment by folding a plurality of scissor arms, etc., and different first adjusting members can be selected according to the size of the tunnel variable-section diameter.

[0052] Preferably, the gantry assembly 1 further includes: a second adjusting member 15, which is detachably installed between the bench 12 and the lining formwork assembly 3, and the distance adjusted by the second adjusting member 15 is adapted to the change amount of the variable-section diameter.

[0053] In this embodiment, after the variable-diameter telescopic assembly is fully extended or retracted, due to the large weight of the lining formwork assembly itself, if the variable-diameter telescopic assembly continues to bear the gravity of the lining formwork assembly for a long time at this time, the telescopic performance of the variable-diameter telescopic assembly will be damaged, and even the variable-diameter telescopic assembly may be damaged, resulting in the inoperability of the rapid variable-section TBM synchronous lining trolley. Therefore, a second adjusting member is added at the contact position between the bench and the lining formwork assembly to bear the gravity of the lining formwork assembly, which can improve the service life of the rapid variable-section TBM synchronous lining trolley; at the same time, the distance adjusted by the second adjusting member is adapted to the change amount of the tunnel variable-section diameter, and the telescopic change amount of the variable-diameter telescopic assembly is no longer used to adapt to the change amount of the tunnel variable-section diameter, which can improve the accuracy of the diameter change. Exemplarily, the second adjusting member is provided at the ends of the longitudinal support rod 121, the transverse support rod 122, and the inclined support rod 123. Optionally, the second adjusting member is a set of combined pads with different thicknesses, or a screw adjustment member that realizes distance adjustment by a screw and a thread pair, or a scissor arm distance adjustment member that realizes distance adjustment by folding a plurality of scissor arms, etc.

[0054] More preferably, the variable-diameter telescopic assembly 2 includes: a variable-diameter driving member, exemplified as an oil cylinder, a cylinder, etc.; preferably, the variable-diameter telescopic assembly 2 further includes: a position sensor provided at the telescopic end of the variable-diameter driving member and a limit plate in the telescopic direction of the variable-diameter driving member, and a plurality of limit holes corresponding to different tunnel variable-section diameters are provided on the limit plate.

[0055] In this embodiment, driving components such as oil cylinders and air cylinders are telescoped to drive the diameter change of the lining formwork. Meanwhile, a position sensor is arranged at the telescopic end of the diameter-changing telescopic assembly to detect the telescopic change amount of the diameter-changing telescopic assembly. The limiting holes on the limiting plate are correspondingly arranged according to the diameters of different tunnel variable cross-sections. When the diameter-changing telescopic assembly telescopes, it corresponds to the limiting holes on different limiting plates for limiting, realizing the synchronous diameter change of the TBM synchronous lining trolley with a rapid variable cross-section and verifying whether the diameter-changing length is in place after the diameter change, and improving the diameter change speed of the TBM synchronous lining trolley with a rapid variable cross-section.

[0056] Preferably, referring to Figure 3 , a number of arc-shaped templates connected in sequence, including two groups symmetrically arranged about the central axis of the lining trolley.

[0057] In this embodiment, a number of arc-shaped templates connected in sequence are symmetrically arranged about the central axis, so that under the telescopic action of the diameter-changing telescopic assembly, they move together in the direction away from or close to the gantry assembly. At the same time, all the arc-shaped templates are deformed under the action of the force of the diameter-changing telescopic assembly, and the diameter of the lining formwork assembly is increased or decreased together, which can greatly reduce the thrust and movement stroke required by the diameter-changing telescopic assembly, and increase the reliability and stability of the TBM synchronous lining trolley with a rapid variable cross-section.

[0058] More preferably, at least one pair of adjacent arc-shaped templates are detachably connected. When the diameter of the TBM synchronous lining trolley with a rapid variable cross-section changes, the lengthening assembly is installed or disassembled between this pair of adjacent arc-shaped templates to increase the connection strength between the lengthening assembly and the arc-shaped templates.

[0059] More preferably, referring to Figure 3 , the lining formwork assembly includes a top form 31 arranged above the gantry assembly 1, a first side form 32 hinged to the top form 31, and a second side form 33 detachably connected to the first side form 31. More preferably, a number of lifting hoists are arranged on or / and below the gantry assembly. When the diameter of the variable cross-section is required, two adjacent arc-shaped templates in the lining formwork assembly are disassembled, the lower arc-shaped template is lifted by the lifting hoist, and at the same time, the arc-shaped template is released to a suitable position, and the lengthening assembly is installed between the two arc-shaped templates to form a closed cross-section of the predetermined design, which can prevent the arc-shaped template from falling and injuring other devices and operators, and improve the safety of the TBM synchronous lining trolley with a rapid variable cross-section.

[0060] More preferably, referring to Figure 4 , each arc-shaped template includes: a bending plate 311, flange plates 312 arranged before and after the bending plate, and connecting side plates 313 arranged on the left and right sides of the bending plate; the two arc-shaped templates are hinged through the connecting side plates 313, and a "V"-shaped notch 314 is arranged at the connecting side plates 313 of the two arc-shaped templates.

[0061] In this embodiment, the arc-shaped templates are hinged to each other and provided with "V"-shaped notches. When the diameter of the quick variable-section TBM synchronous lining trolley increases or decreases, the arc-shaped templates rotate relative to each other. Due to the existence of the "V"-shaped notches, there is a margin for rotation between the arc-shaped templates in pairs, and mutual interference can be avoided during the rotation process and the deformation process. Specifically, when the diameter of the quick variable-section TBM synchronous lining trolley increases or decreases, the "V"-shaped notches of the connecting side plates 313 of the two arc-shaped templates increase or decrease due to rotation and deformation, which can completely avoid mutual interference.

[0062] More preferably, the flange plate 312 on the arc-shaped template includes a plurality of connecting plates connected in sequence, and gaps are provided between the connecting plates.

[0063] In this embodiment, under the telescopic action of the variable-diameter telescopic assembly, the curved plate of the arc-shaped template deforms, and the curvature of the curved plate changes to adapt to the new diameter. At this time, the flange plate connected to the curved plate also needs to deform with the curved plate. Since the flange plate includes connecting plates connected in sequence and gaps are provided between the connecting plates, the connecting plates can approach or move away along the gaps, and cooperate with the change in the curvature of the curved plate to adapt to the new diameter. For example, the flange plate of the arc-shaped template includes a first connecting plate and a second connecting plate connected in sequence, and gaps are provided on the first connecting plate and the second connecting plate. When the curved plate on the arc-shaped template deforms under the telescopic action of the variable-diameter telescopic assembly and the curvature changes, the first connecting plate and the second connecting plate of the flange plate connected to the curved plate approach or move away along the gaps, and cooperate with the change in the curvature of the curved plate to adapt to the new diameter, with a simple structure and easy implementation.

[0064] More preferably, the lengthening assembly can be, but is not limited to, a short arc surface. A plurality of short arc surfaces of different sizes can be set according to the variable-diameter range of the variable-section TBM lining trolley to make up for the size of the notch after the diameter change. For example, the variable-diameter range can be selected between 9.5 - 10.5 m to improve the applicable range of the lining trolley.

[0065] The present invention also provides a quick variable-section method. Taking the increase in the cross-section diameter as an example, the reverse operation can be performed for the reduction in the cross-section diameter. Refer to Figures 1-4 , and applying the above variable-section TBM synchronous lining trolley, the method includes the following steps:

[0066] S10. The gantry assembly 1 and the lining formwork assembly 3 are disassembled and separated;

[0067] S20. The variable-diameter telescopic assembly 2 extends, driving the lining formwork assembly 3 to move to a predetermined diameter position on the side away from the gantry assembly 1; the lining formwork assembly 3 as a whole deforms, and the corresponding perimeter increases, forming a closed cross-section notch with the track at the bottom of the tunnel;

[0068] S30. The lengthening component 4 is installed on the lining formwork 2 to fill the closed section gap formed between the lining formwork assembly 3 and the tunnel bottom track, thereby forming a closed section of the predetermined design.

[0069] S40. The gantry assembly 1 is installed and connected to the lining formwork assembly 3 and the lengthening component 4.

[0070] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed. The combination of its technical effects and technical features will not be elaborated herein, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
