Description

Technical Field

[0001] The utility model relates to a tunnel construction machine, in particular to a tunnel bottom plate formwork concrete lining trolley. Background Art

After the pouring is completed, the concrete is completely hardened (that is, the concrete is in the strength period), and then the formwork is removed, and then the formwork is moved to the next station for repeated pouring. However, this pouring method has the following disadvantages:

[0003] Since the formwork needs to be erected, dismantled and moved multiple times, the construction efficiency is low, the construction progress is slow, the manual labor intensity is high, and the loss of auxiliary materials and consumables is high.

[0012] When the locking portion of the lock tongue contacts the rail, the lower locking block is lifted upward, the locking portion of the lower locking block contacts the rail, and the rail is clamped by the upper and lower locking portions; after the upper locking portion is separated from the rail, the lower locking portion is also separated from the rail, releasing the clamping force of the upper and lower locking portions on the rail.

[0051] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0052] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0053] As mentioned in the background technology, the current tunnel secondary lining pouring construction usually adopts two methods: full-section pouring and separate pouring of the bottom plate and the side top arch. In the process of pouring the bottom plate, the traditional pouring method is: after the formwork is set up at a station, pouring is carried out. After the pouring is completed, the concrete is completely hardened (that is, the concrete is in the strength stage), and then the formwork is removed, and then the formwork is moved to the next station for repeated pouring. However, this pouring method has the following disadvantages:

[0054] Since the formwork needs to be erected, dismantled and moved multiple times, the construction efficiency is low, the construction progress is slow, the manual labor intensity is high, and the loss of auxiliary materials and consumables is high. In addition, the concrete is in a hardened state after demolding. If the casting surface has quality problems such as honeycombed surface, cold joints, misaligned joints, etc., it is difficult to repair.

[0055] Based on the above problems, this embodiment provides a tunnel floor formwork concrete lining trolley, such as Figure 1-Figure 3As shown, the trolley includes a frame 200, a needle beam 100 and a bottom mold assembly 300. The needle beam 100 is installed in the construction tunnel along the tunnel axis. The frame 200 is slidably installed on the needle beam 100. The needle beam 100 runs through the frame 200. A frame walking mechanism 400 adapted to the needle beam is installed on the frame 200. The bottom mold assembly 300 is located in the casting area and connected to the frame 200. The bottom mold assembly 300 moves with the frame 200; the bottom mold assembly 300 includes a bottom mold and side molds 302 located on both sides of the bottom mold 301. The side molds 302 are hinged to the bottom mold 301. The bottom mold 301 is fixedly connected to the lower part of the frame 200. The side mold 302 is connected to the frame 200 through a support member 600 and / or a support cylinder 700 to realize a vertical mold. The support member 600 can be a screw jack or other tools that can play a supporting role. For example, Figure 4 and Figure 5 As shown, the frame 200 includes a column 201, a cross beam 202 and a longitudinal beam 203 are respectively installed at the upper and lower ends of the column, a string beam 204 is arranged below the longitudinal beam 203, and a stand column 205 is arranged below the string beam; at the same time, walking wheels 206 adapted to the needle beam are arranged below the cross beam and / or above the string beam.

[0056] The above technical features use the needle beam and the frame to move the formwork and continuously pour, thereby avoiding multiple formwork removals and reducing the labor intensity of the workers. Because it is a formwork dragging method, the formwork can be dragged to the next station for continuous pouring when the concrete is not completely hardened (that is, the concrete is in the setting period), thereby improving construction efficiency and speeding up construction progress. In the above technical features, when the formwork is pouring, if Fig.16 As shown, concrete enters the discharge troughs on both sides from the main hopper 900 using the chute 901, and then enters under the formwork for pouring. After the pouring is completed, when the concrete is in the setting period, the frame can enter the next pouring station under the action of the frame walking mechanism. During this process, the formwork group is dragged to the next station by the frame, and the formwork group can repair the pouring surface during the dragging process.

[0057] In order to realize the movement of the frame on the needle beam, such as Figure 6 and Figure 7 As shown, in one embodiment, the frame walking mechanism 400 includes a walking cylinder 401, and moving components installed on a rail 402 are respectively connected to both ends of the walking cylinder 401; the moving component has a locking tongue 405 that is adapted to and rotatable with the rail, and the rail 402 is fixedly installed on the needle beam 100, and one of the moving components is connected to the frame 200.

[0058] The moving assembly includes a locking frame 404, a locking cylinder 403 and a locking tongue 405;

[0059] The steel rail 402 passes through the locking frame 404, wherein the locking frame 404 of the moving assembly connected to the frame 200 is connected to the frame 200 through a hinge seat 406;

[0060] The middle part of the locking tongue 405 is hinged to the locking frame 407, one end of the locking tongue 405 has a locking portion adapted to the upper surface of the rail 402, and the other end is hinged to one end of the locking cylinder 403;

[0061] The other end of the locking cylinder 403 is hinged to the locking frame 404 .

[0062] A lower locking block 407 is provided at the gap between the lower surface of the steel rail 402 and the locking frame 404. The lower locking block 407 is fixedly connected to the locking frame 404, and a locking portion adapted to the lower portion of the steel rail 402 is provided at the upper end of the lower locking block 407;

[0063] When the locking portion of the locking tongue 405 contacts the rail, the lower locking block is lifted upward, the locking portion of the lower locking block contacts the rail, and the rail is clamped by the upper and lower locking portions; after the upper locking portion is separated from the rail, the lower locking portion is also separated from the rail, releasing the clamping force of the upper and lower locking portions on the rail.

[0064] The above-mentioned technical features use the form of oil cylinder pushing or pulling to drive the frame to move continuously on the needle beam. Driving the frame to move in this way can ensure the stability and reliability of the frame when moving, and provide greater driving force for the dragging of the template group; in the above-mentioned technical features, when the frame moves, the moving component away from the frame end is locked (that is, the moving component and the rail remain fixed and no relative movement occurs), and the moving component connected to the frame end is in an unlocked state (that is, the moving component and the rail can have relative movement), and then the walking cylinder is controlled to extend the telescopic rod to drive the frame to move on the needle beam by ejection; when the stroke of a walking cylinder is completed, the moving component away from the frame end is unlocked, the moving component connected to the frame end is locked, the walking cylinder is recovered, and the moving component away from the frame end is dragged to move; when the frame needs to continue to be moved, the above steps can be repeated.

[0065] In the above technical features, the locking principle of the moving assembly is: the telescopic movement of the locking cylinder drives the locking tongue to rotate. When the locking part of the locking tongue contacts the rail, the locking cylinder continues to drive. At this time, the locking frame is lifted up (i.e., the gap between the lower surface of the rail and the lower locking block is reduced). The rail is clamped between the locking tongue and the lower locking block, and the locking is completed by the upper and lower locking parts (i.e., the moving assembly and the rail remain fixed and no relative movement occurs).

[0066] The unlocking principle of the moving assembly is as follows: after the moving assembly is in a locked state, the locking cylinder telescopes in the opposite direction to drive the locking tongue to disengage from the rail. After the locking tongue is disengaged from the rail, the gap between the lower locking block and the rail increases until they are separated, thereby achieving unlocking of the moving assembly and the rail (i.e., the moving assembly and the rail can have relative movement).

[0067] In order to improve the locking ability, in one embodiment, the locking portion is formed by a plurality of convex teeth; this technical feature can improve the anti-slip ability of the locking tongue or the lower locking block after contacting the rail, thereby improving the locking ability.

[0068] In order to realize the movement of the frame on the needle beam, such as Fig. 9 and Fig.10 As shown, in one embodiment, the frame travel mechanism is an electric hoist 500 or a winch connected to the frame 200 at one end and to the needle beam 100 at the other end, or the electric hoist / winch is used in conjunction with the travel cylinder with the moving component. The above technical features can improve the mobility of the frame, thereby improving the ability to drag the mold.

[0069] In order to realize the movement of the needle beam in the tunnel, Figure 2 and Figure 11-Figure 14 As shown, in one embodiment, the needle beam 100 is installed in the tunnel through two fixed leg assemblies 101, and the fixed leg assembly 101 includes two support legs 1013. The lower part of the support leg 1013 is installed with a translation trolley 1016 arranged transversely of the tunnel. The translation trolley 1016 is installed on a support 1011 arranged in the tunnel. A limiter adapted to the trolley is installed on the support. A transverse adjustment cylinder 1012 is installed on the support. One end of the transverse adjustment cylinder 1012 is connected to the support 1011, and the other end is connected to one of the translation trolleys 1016; the support leg 1013 is installed on a slide 1015 through a sleeve 1014, and the slide is connected to the translation trolley. In order to ensure the support stability, a transverse connecting frame 1014 is installed between the two support legs; the support is in an arc shape (such as Fig.13 As shown in Figure 2), the tunnel is rectangular when it is poured (as shown in Figure 2). Fig.11 as shown).

[0070] The needle beam is also equipped with a movable leg assembly 102 with adjustable support height (the movable leg assembly is installed on the needle beam through sliding walking wheels, and has a telescopic cylinder at the bottom to achieve adjustable support height), and the movable leg assembly is located between the two fixed leg assemblies.

[0071] The needle beam is provided with a needle beam traveling mechanism, and the needle beam traveling mechanism is a winch or an electric hoist. At the section to be constructed at the front end of the tunnel, there is an anchor point 900 matching the needle beam traveling mechanism.

[0072] The above technical features can support the needle beam and adjust the position of the needle beam in the horizontal and vertical directions, thereby adjusting the position of the formwork assembly, so that the formwork group can be placed in the specified position for casting. When the frame reaches the maximum stroke and the needle beam needs to be moved, the movable leg assembly is lowered, the two fixed leg assemblies of the needle beam are lifted, and the needle beam is moved by the needle beam walking mechanism (at this time, the formwork and the movable leg assembly are used as support). When the needle beam moves to the specified position, the support is moved and placed, and then the fixed leg assembly is lowered to complete the movement of the needle beam. In this process, the lifting or lowering of the movable leg assembly or the fixed leg assembly is achieved by a telescopic cylinder. The lifting refers to the separation of the support and the leg assembly, and the lowering refers to the contact of the support assembly with the support and the completion of the support.

[0073] In the above technical features, the height of the needle beam is adjusted by the telescopic cylinder of the supporting leg, thereby realizing the height adjustment of the formwork group installed on the frame (that is, completing the adjustment of the pouring thickness); the adjustment of the lateral position of the needle beam is achieved by the lateral adjustment cylinder installed on the support, and the moving trolley of the supporting leg is driven by the lateral adjustment cylinder to move on the support, and when the moving trolley reaches the specified position, the position of the moving trolley is locked.

[0074] When pouring concrete, the concrete will give the formwork an upward buoyancy, which can easily cause the formwork to be misaligned, and ultimately lead to pouring that does not meet the requirements. Therefore, in order to overcome this problem, Figure 2 , Figure 3 , Fig.14 and Fig.15 In one embodiment, the needle beam 100 is installed with an anti-floating frame 800, and the upper end of the anti-floating frame is fixedly connected to the top of the tunnel through an anti-floating top rod 801; the top rod is connected to a telescopic cylinder, and when the anti-floating top rod contacts the top of the tunnel, the telescopic cylinder is locked, thereby fixing the vertical position of the anti-floating frame, and through the limit at the top, the problem of misalignment of the template caused by buoyancy is overcome.

[0075] In order to adjust the horizontal position of the fixed template and improve the pouring quality, horizontal brackets 802 fixedly connected to the two sides of the tunnel are installed on both sides of the anti-floating frame 800, and the ends of the horizontal brackets have telescopic cylinders. The horizontal position of the needle beam is fixed by the horizontal bracket, thereby fixing the position of the needle beam, ensuring that the template is in an accurate position during pouring, and improving the pouring quality.

[0076] After the formwork group is pulled away from the casting surface, if the casting surface still has quality problems such as honeycomb surface, cold joints, misaligned joints, etc., Figure 8As shown, the worker can stand on the working platform 103 located at the end of the needle beam to enter the needle beam and perform repairs above the part that needs repair (because the concrete is still in the setting period at this time and can be further repaired). In order to facilitate the worker's operation, the working platform is provided with a ladder 104.

[0077] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
