Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The bracket 51, the first trolley positioning jack 52, the third trolley positioning jack 53, the fifth trolley positioning jack 54, the horizontal push-pull jack 55, the horizontal push-pull structure 56, and the horizontal push-pull support beam 57; the bottom of the transport connection hinge support 41 is provided with a transport connection bracket 51; the horizontal push-pull jack 55, the horizontal push-pull structure 56, the transport control unit 3, the first trolley positioning jack 52, the third trolley positioning jack 53 and the fifth trolley positioning jack 54 are provided below the transport connection bracket 51; one end of the horizontal push-pull structure 56 is fixedly connected to the horizontal push-pull jack 55, and the other end is fixedly connected to the transport connection hinge support 41 through the horizontal push-pull support beam 57.

[0026] Specifically, if Figure 2 As shown, the present invention is a multifunctional lining trolley for tunnel lining construction. The top of the trolley is a lining template assembly 1 supported according to the internal contour and shape of the tunnel. A door frame 2 is provided on the left and right sides of the lining template assembly 1. The lining template assembly 1 and the door frame 2 are both prior arts. Figure 3 As shown, the longitudinal column of the main load-bearing core portal frame 2 of the trolley adopts variable-section welded H (1800-580)-L2700×400×18 steel, and the transverse beam adopts an I-beam welded from 18mm thick steel plates, with a height of 1450mm, a width of 400mm, and a length of 8400mm. It has strong bending resistance, and the maximum deflection during use is only 0.4mm, so as to ensure that the runout of the trolley is always less than 1mm. The clearance under the portal frame 2 is not less than 4.5m, which meets the requirements for the passage of large equipment required for the front construction of the tunnel lining; the height of each platform of the truss meets the requirements of concrete construction, which is conducive to workers to carry out construction operations such as pipe installation and concrete tamping. There are up and down ladders on the left and right sides of the portal frame 2 to ensure the safety of construction workers.

[0027] like Figure 1 As shown, in order to realize the automatic movement of the trolley, a first moving assembly 4 and a second moving assembly 5 are provided at the bottom of the gantry 2, wherein Figure 4As shown, the first transport assembly 4 includes: a transport connection hinge support 41, a second trolley positioning jack 42, a fourth trolley positioning jack 43, a first cylinder support hinge 44, and a second cylinder support hinge 45; Figure 5 As shown, the second transport assembly 5 includes: a transport connection bracket 51, a first trolley positioning jack 52, a third trolley positioning jack 53, a fifth trolley positioning jack 54, a horizontal push-pull jack 55, a horizontal push-pull structure 56, and a horizontal push-pull support beam 57;

[0028] like Figure 1 As shown, the transport connection hinge support 41 and the transport connection bracket 51 located below the door frame 2 are the main supporting structures of the first transport component 4 and the second transport component respectively. Figure 6 As shown, the two sides of the transport connection hinge support 41 are provided with slots. When not transported, the transport connection bracket 51 is in the slots; when transported, the transport connection bracket 51 moves horizontally and leaves the slots. The transport connection hinge support 41 is provided with two trolley positioning jacks as vertical power support points, and two cylinder support hinges as auxiliary supports; the transport connection bracket 51 is provided with three trolley positioning jacks as vertical power support points, as shown in FIG. Figure 7 As shown, a horizontal push-pull jack 55, a horizontal push-pull structure 56, and a horizontal push-pull support beam 57 are also provided below the transport connection bracket 51 as a power support structure for the two-part transport assembly to achieve horizontal movement. The horizontal push-pull jack 55 provides power, so that the horizontal push-pull structure 56 drives the transport connection bracket 51 to move horizontally and disengage from the slot of the transport connection hinge support 41. At this time, the horizontal push-pull support beam 57 plays a supporting role.

[0029] When the trolley is in a stationary state, the first moving assembly 4 and the second moving assembly 5 overlap at the horizontal axis of the gantry 2, and the respective trolley positioning jacks jointly play a supporting role. When the trolley moves, the first moving assembly 4 and the second moving assembly 5 can automatically perform displacement actions by connecting to the movement control system.

[0030] The specific migration process is as follows:

[0031] Step 1: The first trolley positioning jack 52, the third trolley positioning jack 53, and the fifth trolley positioning jack 54 are retracted upward and off the ground, driving the second transport assembly 5 to leave the ground as a whole. At this time, the upper structure of the trolley is supported by the first transport assembly 4, and the horizontal push-pull jack 55 provides power, so that the horizontal push-pull structure 56 drives the second transport assembly 5 to move forward horizontally;

[0032] Step 2: The first trolley positioning jack 52, the third trolley positioning jack 53, and the fifth trolley positioning jack 54 extend downward, so that the first transport assembly 4 leaves the ground, and the upper structure of the trolley is supported by the second transport assembly 5. The horizontal push-pull jack 55 provides power, so that the horizontal push-pull structure 56 drives the first transport assembly 4 to move forward horizontally;

[0033] Repeat the above process to realize the overall movement of the trolley.

[0034] like Figure 1 As shown, the trolley positioning jack is the main power point of the present invention, which can support the trolley structure body and realize vertical displacement.

[0035] Overall implementation process:

[0036] 1. Device production. The trolley is manufactured in the factory. When assembled on site, its centerline, section and clearance dimensions are checked. Before lining, the formwork is polished, rust-removed, and oiled to prevent rust. The joints of the formwork plates are checked to ensure the smoothness of the formwork. The warping and deformation of the formwork during use that affects the surface quality of the concrete is suppressed, and the misalignment of the joints between the plates is avoided.

[0037] 2. Assembly. First assemble the door frame 2 and the top steel beam 7 on the ground at the site. Then hoist them one by one to the relative position of the bottom longitudinal beam and temporarily fix them with bolts. In order to form an organic whole as soon as possible, install the scissor braces and horizontal braces set in each space immediately after installing the door frame 2. Adjust and align them in time. And tighten the bolts of each part in time to form a complete skeleton.

[0038] 3. Formwork erection. Move the trolley horizontally to the formwork erection position. At this time, the center line of the trolley is consistent with the center line of the tunnel, and the deviation should be less than 50mm. After the trolley is braked in place, alternately start the template transverse jack 13, the horizontal displacement jack 8, and the trolley positioning jack to make the lining template assembly 1 stand at the design required position. Adjust the bracket column 6 and the cylinder support hinge to prevent the longitudinal beam of the portal frame 2 and the longitudinal beam of the top form support from deformation. Install other jacks and adjust them to make the trolley template reach the pouring state.

[0039] 4. Adjustment. (1) Front-to-rear adjustment: This is done through the first transport assembly 4 and the second transport assembly 5. (2) Left-right lateral adjustment: This is done through the foundation positioning jack 18 within 50 mm. If this exceeds 50 mm, the template needs to be hoisted and relocated. (3) Template height adjustment: This is done through the trolley positioning jack.

[0040] 5. Pour concrete into the lining structure through the pumping port 17.

[0041] 6. Remove the formwork. First remove the structural lateral connecting beam 11 and the transverse connecting beam 12 to remove the supporting force of the lining formwork assembly 1. Then retract the template transverse jack 13 and the horizontal displacement jack 8 to unload the transverse thrust, and then retract the trolley positioning jack to completely separate the lining formwork assembly 1 from the lining and retract it to the translation operation state. Remove the concrete bonded to the surface of the lining formwork assembly 1 and apply a release agent (machine oil).

[0042] 7. Move horizontally to the next area for lining construction.

[0043] Furthermore, a cable trough 16 and a pumping port 17 are provided on the lining formwork assembly 1 ; the cable trough 16 is arranged on both sides of the bottom of the lining formwork assembly 1 ; and a plurality of pumping ports 17 are arranged at intervals on the lining formwork assembly 1 .

[0044] Specifically, if Figure 2 As shown, considering the protection of the cable trough 16 engineering components and the need to connect a water pump, a cable trough 16 is set on both sides of the bottom of the lining formwork assembly 1, and a plurality of pumping ports 17 communicating with the inside and outside are arranged at intervals on the lining formwork assembly 1, which can effectively prevent collision damage to the existing cable trough 16 structure during construction, facilitate the connection of the water pump, and improve construction quality and efficiency.

[0045] Furthermore, it also includes: a supporting structure; a supporting structure, including: at least two bracket columns 6, a top steel beam 7, a rectangular steel truss support 9, a transverse steel truss support 10, a lateral connecting beam 11, a transverse connecting beam 12, a template transverse jack 13 and a mold foot support rod 14; the bracket column 6 is fixedly connected to the upper inner side of the lining template assembly 1; the lower end of the bracket column 6 is fixedly connected to the top steel beam 7; two door frames 2 are arranged below the top steel beam 7, and the rectangular steel truss support 9 and the transverse steel truss support 10 are located on the end face of the door frame 2 facing the lining template assembly 1; a lateral connecting beam 11 and a transverse connecting beam 12 are provided between the rectangular steel truss support 9 and the lining template assembly 1; a template transverse jack 13 and a mold foot support rod 14 are provided between the transverse steel truss support 10 and the lining template assembly 1.

[0046] Specifically, if Figure 2As shown, the bracket column 6 and the top steel beam 7 are the upper support structure of the lining trolley. The support structure is a fixed support structure. According to the length of the top steel beam 7, multiple bracket columns 6 are set to support the lining formwork assembly (1) stably. The rectangular steel truss support 9, the transverse steel truss support 10, the lateral connecting beam 11, the transverse connecting beam 12, the template transverse jack 13 and the mold foot support rod 14 are the transverse support structure of the lining trolley. The template transverse jack 13 adopts a hydraulic cylinder, which can cooperate with the adjustment structure to achieve transverse adjustment while playing a supporting role; the rectangular steel truss support 9 and the transverse steel truss support 10 are welded to the portal 2, and are used to connect the lateral connecting beam 11 and the transverse connecting beam 12, so as to achieve the fixation of the lining formwork assembly 1. By setting the support structure, the lifting function of the lining trolley is optimized, and it can be adjusted according to the size of the internal contour of the tunnel, effectively ensuring the stability and safety of the tunnel project.

[0047] Furthermore, it also includes: an adjustment structure; an adjustment structure, including: a horizontal displacement jack 8, a mold foot supporting jack 15, and a basic positioning jack 18; a horizontal displacement jack 8 is provided at the connection end between the top steel beam 7 and the two door frames 2; a mold foot supporting jack 15 is provided at the connection end between the mold foot support rod 14 and the lining formwork assembly 1; a basic positioning jack 18 is provided on one side of the first cylinder support hinge 44 and the second cylinder support hinge 45.

[0048] Specifically, if Figure 2 As shown, the template transverse jack 13 cooperates with the horizontal displacement jack 8 to realize the lateral adjustment of the lining template assembly 1. One end of the mold foot supporting jack 15 is connected to the lining template assembly 1 in a hinged manner, and the other end is a free end. The structure can be folded up when the trolley moves, and the structure can be lowered to support the ground when the trolley is fixed. When the trolley is fixed, the mold foot supporting jack 15 can fine-tune the position and left-right balance of the lining template assembly 1 to make the structure of the lining template assembly 1 stable. One end of the mold foot supporting jack 15 is connected to the lining template assembly 1 in a hinged manner, and the other end is a free end. The structure can be folded up when the trolley moves, and the structure can be lowered to support the ground when the trolley is fixed. The foundation positioning jack 18 is an auxiliary structure of the trolley positioning jack, which can prevent lateral deviation that may occur during the movement of the trolley and realize lateral fine-tuning of the trolley. The adjustment structure has two main functions. First, the lining formwork assembly 1 can be adjusted to adapt to the tunnel contour and better play an overall supporting role. Second, after the trolley is assembled and moved, fine-tuning can be performed to improve the overall stability of the trolley and ensure the safety of the project.

[0049] Furthermore, air duct passage openings are respectively reserved between the rectangular steel truss supports 9 and the transverse steel truss supports 10 on the left and right sides; the diameter of the air duct passage opening is greater than / equal to the diameter of the tunnel air duct.

[0050] Specifically, if Figure 2 As shown, in order to ensure ventilation needs in tunnel projects, air ducts must be installed. Considering the protection of air duct project components, air duct openings are reserved on the left and right sides of the trolley. This can prevent the trolley from damaging the original air duct during construction, causing poor ventilation inside the tunnel, thereby ensuring construction safety.

[0051] Furthermore, the first trolley positioning jack 52 , the third trolley positioning jack 53 , the fifth trolley positioning jack 54 , the second trolley positioning jack 42 and the fourth trolley positioning jack 43 are provided with hydraulic locking cylinders.

[0052] Specifically, if Figure 3 As shown, since the operating pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the weight of the upper structure of the gantry 2 is very large, and the cylinder cannot be used as a high-power power element. The hydraulic system adopts a pressure value of 26MPa, a flow value of 14.5L / min, a cylinder diameter of 200mm, and a stroke of 250mm. It can support a sufficiently large power output to support the overall weight of the trolley. In addition, a hydraulic lock is configured to lock at a fixed point to ensure the safe movement of the trolley.

[0053] Furthermore, hydraulic cylinders are provided on the first cylinder support hinge 44 and the second cylinder support hinge 45 .

[0054] Specifically, if Figure 3 As shown, the cylinder support hinge is composed of a support hinge, a cylinder, and a support. The support hinge itself has high strength and is made of steel, but does not have a power system and is only a vertical support. A hydraulic cylinder is set between the support hinge and the support to assist the second trolley positioning jack 42 and the fourth trolley positioning jack 43 in providing power to support the overall structure when the trolley is moved, making the movement smoother and safer.

[0055] Furthermore, a portal frame supporting jack (19) is provided on one side of each of the two portal frames (2).

[0056] Specifically, if Figure 2 As shown, in this embodiment, a gantry support jack 19 is respectively arranged on one side of the two gantry frames 2, one end of the gantry support jack is hinged to the bottom support foot of the gantry frame 2, and the other end is a free end. The structure can be folded up when the trolley moves, and the structure can be lowered to support the ground when the trolley is fixed. Its main function is to position and prevent the gantry frame 2 from moving sideways.

[0057] Overall beneficial effects:

[0058] 1. It can realize the function of trackless self-movement, which improves the construction efficiency.

[0059] 2. It can simultaneously meet the lifting, bearing, grouting and other construction requirements of lining construction, thus improving construction efficiency;

[0060] 3. Reserved openings for cable troughs, pumping ports and air ducts are provided to facilitate structural connection operations during lining construction.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
