[0042] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] As Figures 1-3 shown, a tunnel lining device of the present invention includes:

[0044] The main gantry structure 1, having a hollow area C suitable for passing through a vehicle;

[0045] The conveying mechanism 2, spanning across two sides and the upper part of the main gantry structure 1 and connected to the main gantry structure 1, for circumferentially conveying a lining structure (not marked here) along the periphery R of the main gantry structure 1;

[0046] The jacking mechanism 3, having a support end 31 and a jacking end 32. Among them, the support end 31 is connected to the main gantry structure 1, and the jacking end 31 can perform telescopic movement along the radial direction X and is suitable for radially jacking the lining structure located on the conveying mechanism 2 away from the conveying mechanism;

[0047] The driving mechanism 4, connected to the conveying mechanism 2, for driving the conveying mechanism 2; among them, the driving mechanism 4 preferably includes a reduction motor 41 connected to a driving wheel 21 and a driving motor 42 connected to the reduction motor 41;

[0048] The fine adjustment mechanism 5, arranged on the main gantry structure 1, for adjusting the relative positional relationship between the conveying mechanism 2 and the main gantry structure 1 in the axial direction of the main gantry structure 1;

[0049] A control mechanism, connected to the lifting mechanism 3, the driving mechanism 4, and the fine-tuning mechanism 5, is adapted to control the lifting mechanism 3, the driving mechanism 4, and the fine-tuning mechanism 5.

[0050] The main gantry structure 1 may include a trolley main structure 11 and a support framework 12 disposed on the trolley main structure. Among them, the support framework 12 may be fixedly arranged on the trolley main structure 11; or may be axially movably cooperated, and the axis is perpendicular to the radial direction in which the lifting mechanism 3 is arranged and / or the circumferential direction of the main gantry structure 1. More specifically, when the tunnel lining equipment of this embodiment is placed in a tunnel for implementation, the axis is the extension direction of the tunnel.

[0051] The conveying mechanism 2 is disposed on the support framework 12. One end of the fine-tuning mechanism 5 is disposed on the trolley main structure 11, and the other end is connected to the support framework 12, and is used to drive the support framework 12 to drive the conveying mechanism 2 to reciprocate along the axis.

[0052] Specifically, the trolley main structure 11 has a guide groove 13 extending along the axis, and the support framework 12 has a guide structure 14 disposed in the guide groove 13 and movably connected to the guide groove. As one implementation manner, the guide structure 14 is a guide rail, and the movable connection is a sliding connection. As another implementation manner, the guide structure 14 is a roller mechanism, including a roller and a mounting structure for mounting the roller on the conveying mechanism, and the movable connection is a rolling connection between the roller and the guide groove.

[0053] The fine-tuning mechanism includes an oil cylinder mechanism that can be telescoped along the axis, or includes a transmission component and a stepping motor connected to the transmission component.

[0054] In addition, the traveling mechanism 6 is disposed at the bottom of the trolley main structure 11, and the supporting end 31 of the lifting mechanism 3 is disposed on the support framework 12. The lifting mechanism 3 may be an oil cylinder mechanism or a threaded telescopic mechanism. The connection structure 24 may be a hanging hook nail, or other structures that can be quickly cooperated with the lining structure and are convenient for separation. Preferably, the lining structure is an arc-shaped corrugated steel plate. Among them, the hanging hook nail has a protruding structure extending along the telescopic direction of the lifting mechanism, and a concave structure adapted to be inserted and cooperated with the protruding structure is formed on the arc-shaped corrugated steel plate, and the concave structure and the protruding structure are only slidably cooperated in the telescopic direction of the lifting mechanism.

[0055] The traveling mechanism 6 has a steering device controlled by the control mechanism, and the supporting end of the lifting mechanism is disposed on the support framework.

[0056] The conveying mechanism 2 may specifically include: a driving wheel 21; a driven wheel 22; a chain structure 23 disposed on the driving wheel 21 and the driven wheel 22, wherein a connecting structure 24 adapted to be connected to the inner lining structure is provided on the chain structure 23; and a mounting structure 25 for mounting the driving wheel 21 and the driven wheel 22 on the main gantry structure 1. The driving wheel 21 is preferably connected to the speed reducer 41, and the speed reducer 41 is connected to the driving motor 42. The mounting structure 25 may specifically include a first mounting seat 251 for mounting the driving wheel 21 and a second mounting seat 252 for mounting the driven wheel 22; further, at least one of the driving wheel 21 and the driven wheel 22 has a guiding function for the chain structure 23. A traveling mechanism 6 may be provided at the bottom of the main gantry structure 1.

[0057] The chain structure 23 may be a chain; as Figure 4 shown, the chain structure 23 may also be a wire rope.

[0058] As a preferred embodiment, the tunnel lining device of this embodiment further includes a device lifting mechanism (not marked here), which is disposed at the lower part of the main gantry device, is controlled by the control mechanism, and is used to lift and lower the tunnel lining device. The device lifting mechanism may include at least lifting cylinders located at the four corners of the device. Alternatively, the lifting mechanism may also be located on the traveling mechanism and is used to lift and lower the tunnel lining device through the traveling mechanism.

[0059] The construction process using the above-mentioned tunnel lining device of the present invention includes the following steps:

[0060] Step 1: Place the tunnel lining device at the tunnel construction position to be constructed, and it can be moved to this position through the traveling mechanism and perform axial positioning;

[0061] Step 2: Place the arc-shaped corrugated steel plate as the inner lining structure on the connecting structure on the chain mechanism on one side below the main gantry structure; there is no need to lift it to the top of the main gantry structure through the equipment thereon, and the installation is fast;

[0062] Step 3: Control the driving mechanism through the control mechanism to drive the conveying mechanism to circumferentially convey the arc-shaped corrugated steel plate along the periphery of the main gantry structure to the preliminary position where the inner lining structure needs to be installed;

[0063] Since the tunnel lining equipment is positioned axially, the initial position of the conveying mechanism in the axial direction is also positioned. To convey the arc-shaped corrugated steel plate by controlling the conveying mechanism, only accurate circumferential conveyance needs to be considered; especially when the conveying mechanism is a conveying mechanism with a chain structure, it can be easily achieved through the cooperation of the driving motor and the conveying mechanism; however, due to the possible slight deviation in the axial positioning of the tunnel lining equipment, it is no longer very convenient to continue adjusting the position of the tunnel lining equipment in the axial direction. Therefore, a fine-tuning step is required;

[0064] Step 4: Control the fine-tuning mechanism through the control mechanism to adjust the relative position of the conveying mechanism and the main gantry structure along the axial direction of the main gantry structure, so as to achieve precise positioning of the arc-shaped corrugated steel plate in the axial direction and make up for the inaccurate axial position positioning of the tunnel lining equipment;

[0065] Step 5: Control the jacking mechanism through the control mechanism to jack the arc-shaped corrugated steel plate away from the connecting structure of the chain-type conveying mechanism and jack it to the final position on the inner wall of the tunnel;

[0066] Among them, multiple arc-shaped corrugated steel plates are continuously conveyed through the above steps 1-4, and multiple arc-shaped corrugated steel plates are jacked to the inner wall through the above step 5, which can form a continuous arc-shaped lining structure that fits the inner wall of the tunnel;

[0067] Step 6: Weld or screw-connect the joints of two adjacent arc-shaped corrugated steel plates by construction workers or other equipment to make multiple arc-shaped corrugated steel plates form a whole.

[0068] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
