Description

Technical Field

[0001] The present invention relates to the technical field of lining trolleys, and particularly to an intelligent tunnel lining trolley. Background Technique

[0002] Tunnel lining trolleys are special equipment that must be used in the secondary lining during the tunnel construction process for the concrete lining construction of the inner wall of the tunnel. In existing tunnel lining trolleys, most are designed corresponding to each tunnel one by one, resulting in slow production and preparation of the lining trolleys. In particular, when selecting a lining trolley for tunnels with the same shape but different sizes, if a new lining trolley is still prepared, the tunnel lining efficiency will be low. For some lining trolleys that can adjust their sizes, after adjustment, there are differences in aspects such as the support strength, the direction of the support force, and the support points from the optimal support state of the initial design. Even though they can adapt to tunnels of various sizes, the structure after adjustment is difficult to reach the best structural form, resulting in an increase in the risk coefficient during the lining process. Moreover, when the template separates from the solidified surface after the slurry solidifies, it often causes the surface of the solidified wall to be pulled and torn by the template, and debris even cracks may occur.

Detailed implementation manners

[0035] Referring to Figures 1-5 , the present invention provides a technical solution: an intelligent tunnel lining trolley, which includes:

[0036] Crossbeam frames 1 are arranged in multiple groups parallel to each other before and after in the same horizontal plane and are fixed. A trapezoidal support frame 11 is installed at the center of the upper side of each crossbeam frame 1, a liftable traveling frame 2 arranged longitudinally is installed at the left and right ends of the lower side, and mold expansion devices 6 inclined upward at 45° are symmetrically installed at the left and right ends. The outer surface of the mold expansion device 6 is an arc-shaped curved surface, and lifting rods 21 are respectively hinged at the upper and lower ends of the outer side of the liftable traveling frame 2;

[0037] Hydraulic jacking frames 3 are configured in multiple groups and are respectively vertically installed at the upper ends of the corresponding trapezoidal support frames 11 and horizontally installed at the output ends of the corresponding lifting rods 21 on the upper and lower sides;

[0038] Top formwork 4 is installed corresponding to the vertical hydraulic jacking frames 3;

[0039] The side formwork 5 is installed corresponding to the horizontal hydraulic jacking frame 3, and the side formwork 5, the top formwork 4, and the formwork expanding device 6 are arranged in a concentric circular structure. The lower ends of the left and right side formworks 5 are correspondingly installed with a film covering assembly 9, and grouting holes 7 are provided on both the top formwork 4 and the side formwork 5;

[0040] This structural design is mainly used for: First, for lining trolleys of the same specification size, it can have the function of adjustable size within a certain size range, thereby reducing the manufacturing cost of the lining trolley, increasing the applicable breadth of a single lining trolley, and increasing the adaptation rate of the optional lining trolley for the corresponding tunnel, and then improving the tunnel lining efficiency. Second, through the straight extension and outward expansion structure for outward expansion and inward contraction, the working surface size of the lining trolley is changed. For example, in this structure, when using circular inward contraction and outward expansion, the center of the outer arc surface of the top formwork, side formwork, and formwork expanding device can still be in a concentric structure, so as to ensure that the supporting force of the overall structure and the direction of the relative stress after outward expansion and inward contraction remain unchanged, and still be able to maintain the best supporting structure form. Third, by laying the film covering assembly on the outer sides of the top formwork and the side formwork, when the external slurry solidifies, the adhesion between the solidified wall surface and the formwork is reduced, avoiding the shedding of fragments or cracks on the solidified wall surface when the top formwork and the side formwork are separated from the solidified wall surface, and improving the protection strength of the outer surfaces of the top formwork and the side formwork.

[0041] In this embodiment, the central angle of the arc of the top formwork 4 is 85°. Free rollers I are correspondingly installed at its left and right ends, and corresponding arc-shaped guide rails I 41 are installed on the front and rear inner side wall plates near its left and right ends;

[0042] This structural design method is mainly for, when the straight extension and outward expansion process can be completed, as much as possible to increase the coverage area of the integral structure of the top formwork, reduce the inconvenience caused by the movement of the top formwork composed of multiple fragmented structures, and increase the generation rate of uncontrollable factors during the adjustment process, such as the offset of the structural support structure and the change of the support points of the support points from the original structure, thereby reducing the support strength of the overall structure after adjustment;

[0043] Among them, the design of the free roller I is mainly to assist the operation of the film covering assembly during film covering and relatively reduce the resistance suffered by the film covering.

[0044] In this embodiment, the central angle of the arc of the side formwork 5 is 60°. Free rollers II are correspondingly installed at its upper and lower ends, and corresponding arc-shaped guide rails II 51 are installed on the front and rear inner side wall plates near its upper and lower ends. And the included angle between the adjacent side formwork 5 and the top formwork 4 at the close ends is 5°. Among them, it is the same as the structural design principle of the top formwork.

[0045] In this embodiment, the formwork expanding device 6 is correspondingly arranged inside the top formwork 4 and the side formwork 5, and it includes:

[0046] The concave support shell 63 has strip-shaped guide rails 64 installed on its front and rear side walls, which are inclined 45° upward, and an expanding die assembly 8 is embedded and installed inside it;

[0047] Two sets of hydraulic rods 61 are arranged in parallel front and back and inclined 45° upward, and are hinged and fixed to the front and rear sides of the corresponding ends of the cross beam frame 1, and clamping support members 62 are fixed to their output ends;

[0048] And the clamping support member 62 includes a side clamping frame 621. Inside the side clamping frame 621, push-pull rods 622 are installed side by side front and back and facing away from each other. Side clamping seats 623 are fixed to the output ends of the push-pull rods 622, and the outer ends of the side clamping seats 623 are hinged and fixed to the corresponding strip-shaped guide rails 64 in an adjustable sliding structure;

[0049] In this structural design, first, the overall 45° inclination design method mainly enables the total resultant force of the overall structure to be relatively evenly distributed through the hydraulic rod 61, and the magnitudes of the longitudinal and transverse stress components are kept the same, improving the balance of the overall structure's stress, thereby enhancing the support strength of the expanding die device. Second, the design method of the adjustable clamping support member mainly makes the support point of the clamping support member and the fixed point of the hydraulic rod 61 form an equilateral triangle structure with an included angle of 60°, improving the support strength and stability strength of the expanding die assembly.

[0050] In this embodiment, the expanding die assembly 8 includes:

[0051] An inner arc-shaped support plate 81, whose two ends are slidably connected to the corresponding end faces of the concave support shell 63. Parallel clamping plates 82 are fixed to its outer arc surface and are arranged in a partial circular arrangement. Each group of parallel clamping plates 82 is internally provided with a radially arranged hydraulic rod 83, and the output end of the hydraulic rod 83 is hinged with a top roller 84;

[0052] Two sets of outer arc-shaped support plates 85 are arranged in parallel front and back, and are correspondingly clamped and fixed to the front and rear sides of the upper ends of the corresponding parallel clamping plates. Arc-shaped guide rails 87 are installed at both ends of each of them. Fixed columns 86 passing through the plate wall are installed on the plate wall of the outer arc-shaped support plate 85 near the outer side of the arc-shaped guide rail 87, and the outer ends of the corresponding fixed columns 86 at the corresponding end sides are respectively embedded and slidably connected in the corresponding arc-shaped guide rails 81 and 82;

[0053] Elastic tension members 89 are arranged in parallel front and back in multiple groups, and their two ends are correspondingly hinged to the corresponding fixed columns 86 on one side and slidably connected to the corresponding arc-shaped guide rails 87 on one side;

[0054] An expanding die belt 88 is laid on the outside of the top roller, and its two ends are correspondingly connected to one end of the elastic tension member 89 that is slidably connected to the arc-shaped guide rail 87 at the corresponding end side;

[0055] In this structural design, the top roller is used to support and press the expanding die belt to compensate for the outward expansion notch. Among them, the elastic tension rod is used to externally pull and maintain the tension of the expanding die belt.

[0056] In this embodiment, a strip roller 810 arranged in an array structure is provided inside the expanding die belt 88. The shaft ends of adjacent strip rollers 810 are rotatably connected through the central shaft ring of the ear-shaped collar 811. Micro shaft rings with different upper and lower widths are provided on both sides of the central shaft ring of the ear-shaped collar 811. Adjacent micro shaft rings cross and overlap, and a fixed shaft 812 connecting adjacent micro shaft rings is embedded in the overlapping shaft holes.

[0057] This structural design is mainly used to maintain the flexibility of the expanding die belt, further improve the support strength, and ensure the close fit of the notch compensation surface.

[0058] In this embodiment, a shock-absorbing spring 813 is installed between the side wall of the inner arc-shaped support plate and the strip guide rail 64.

[0059] This structural design is mainly used to improve the support stability of the corresponding components.

[0060] In this embodiment, the film covering assembly 9 includes:

[0061] A winding machine 91, symmetrically arranged inside the corresponding side templates on the left and right sides, and pulling shafts 92 are fixed to the output ends thereof.

[0062] Pulling ropes 93 are arranged in multiple groups side by side in the front and back. The left ends thereof are wound around the corresponding pulling shafts 92 on the left side.

[0063] A pulling belt 94, the right end thereof is wound around the pulling shaft 92 on the right side, and the left end thereof is connected to the corresponding pulling ropes 93 at the right end.

[0064] This structural design is mainly used for the direct contact of the slurry with the top template, side templates and expanding die belt. It should be noted that the pulling belt needs to rise gradually as the slurry rises to avoid covering the shallow grouting holes.

[0065] In this embodiment, the pulling ropes 93 include an outer pulling rope 931 arranged above and an inner pulling rope 932 arranged below. The outer pulling ropes 931 and inner pulling ropes 932 provided on each side are respectively located on the upper and lower end faces of the corresponding side pulling belts 94.

[0066] This structural design is mainly used to press and support the pulling belt. The outer pulling rope positions the pulling belt downward during operation, and the inner pulling rope promotes the sliding of the pulling belt to improve the pulling smoothness rate.

[0067] In specific implementation, a formwork trolley required for tunnel lining of the same shape is selected. According to the tunnel size, through the coordinated telescoping of the hydraulic lifting frame, push-pull rod, and hydraulic rod 1, the top formwork is vertically lifted, the side formwork is horizontally expanded outward, the expansion formwork device is expanded outward at an upward inclination of 45°, and the winding machine is coordinated to release the pulling rope. Then, the hydraulic rod 2 is gradually extended outward to make the top roller press against the expansion formwork surface to compensate for the notch surface formed between the top formwork and the side formwork. When the tunnel size is reached, grouting is carried out on the grouting holes from bottom to top. At the same time, the corresponding winding machine is started to wind up the pulling rope, so that the pulling surface belt and the slurry are in an upward state. At the same time, the pulling surface belt promotes the tumbling of the slurry, accelerating the escape rate of air bubbles inside the slurry until the top formwork, side formwork, and expansion formwork surface are covered. After waiting for the slurry to be filled and solidified, the hydraulic lifting frame, push-pull rod, and hydraulic rod 1 are slightly contracted slightly synchronously, and then the pulling surface belt is gradually uncovered in a circumferential uncovering manner, thereby reducing the pulling damage of the hard adhesion stress to the solidified wall.

[0068] As described above, only the preferred specific implementation mode of the invention is provided, but the protection scope of the invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the invention, according to the technical solution of the invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the invention.
