Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 This utility model provides a tunnel hydraulic mobile integral casting trolley for left and right side cable trenches, including a truss support system 100, a traveling system 200, a formwork system 300, and a hydraulic system 400. The traveling system 200 and the hydraulic system 400 are respectively mounted on the truss support system 100. A formwork system 300 is located on each side of the truss support system 100. The hydraulic system 400 is located between the formwork system 300 and the truss support system 100. The truss support system 100 includes two base rods 110 and a gantry system. The base rods 110 are located above the track. Multiple gantry systems are equidistantly arranged longitudinally along the two base rods 110. A connecting system is provided between adjacent gantry systems. The traveling system 200 is located at each end of the base rods 110. The formwork system 300 includes an inner formwork 310 for the cable trench and a side formwork 320 for the cable trench. The 20 is located between the inner formwork 310 and the bottom rod 110 of the cable trench. The top of the side formwork 320 of the cable trench is detachably connected to the top of the inner formwork 310 of the cable trench by bolts and nuts. The inner formwork 310 of the cable trench has a pouring port. The hydraulic system 400 includes a first lifting system, a second lifting system, a first translation system, and a second translation system. The first lifting system and the first translation system are respectively connected to the inner formwork 310 of the cable trench, and the second lifting system and the second translation system are respectively connected to the side formwork 320 of the cable trench. They are used to control the lifting and horizontal movement of the inner formwork 310 and the side formwork 320 of the cable trench. Through the overall structure and modular design of the truss support system 100, the traveling system 200, the formwork system 300 and the hydraulic system 400, the collaborative work of each system is realized, providing a basic framework for the overall pouring of the cable trench and solving the efficiency and accuracy problems of traditional segmented construction.

[0031] The gantry system includes uprights 120 and crossbars 130. The bottom end of the uprights 120 is fixedly connected to the bottom bar 110, and the two ends of the crossbars 130 are fixedly connected to the two horizontal uprights 120 respectively. The gantry system adopts a rigid connection structure of uprights 120 and crossbars 130. The horizontal span is adapted to the tunnel width. The fixed connection between the uprights 120 and the bottom bar 110 can withstand the vertical load, ensuring that the gantry is stable and does not shake during the pouring process.

[0032] The connection system includes connecting rods 140 and reinforcing rods 150. One connecting rod 140 is fixedly connected between the upper part of the two longitudinal uprights 120 and the end of the two longitudinal horizontal bars 130. A reinforcing rod 150, which is arranged parallel to the uprights 120, is fixedly connected between the upper and lower connecting rods 140. The connection system longitudinally connects the gantry system through the connecting rods 140 and the reinforcing rods 150 to form a grid-like rigid frame, which improves the longitudinal stiffness and prevents the overall formwork from deflecting due to its own weight.

[0033] Among them, the bottom of the upright 120 is fixedly connected to the lower part of the corresponding horizontal bar 130 with a diagonal brace 160; the diagonal brace 160 between the upright 120 and the horizontal bar 130 forms a triangular stable structure, which improves the lateral stiffness and can resist the lateral force during concrete pouring, preventing the gantry system from deforming.

[0034] The traveling system 200 includes a support column 210, a traveling trolley 220, and a first hydraulic cylinder 230. The support column 210 is located near the end of the base rod 110 and adopts a track-type structure. It is driven by hydraulic and electrical means. The bottom of the traveling trolley 220 is equipped with guide wheels adapted to the track to ensure straight travel along the track without deviation. The traveling trolley 220 is installed at the bottom end of the support column 210, and the bottom horizontal line of the traveling trolley 220 is lower than the bottom horizontal line of the base rod 110. The first hydraulic cylinder 230 is located between the support column 210 and the upright 120. The traveling system 200 adopts the design of support column 210, traveling trolley 220, and first hydraulic cylinder 230. The track-type drive achieves smooth speed regulation. The first hydraulic cylinder 230 can adjust the levelness of the trolley. The bottom of the traveling trolley 220 is lower than the base rod 110 to ensure track fit.

[0035] Among them, the outermost upright 120 has a support 121 and a first sliding seat 122 fixedly connected to its side from top to bottom. The first hydraulic cylinder 230 is installed between the support 121 and the support column 210. The support column 210 slides through the inner cavity of the first sliding seat 122. The support 121 and the first sliding seat 122 on the upright 120 provide stable support for the first hydraulic cylinder 230. The sliding of the support column 210 through the first sliding seat 122 can limit its lateral displacement and ensure the stability of the trolley's posture when adjusting the height.

[0036] Among them, a side rod 123 is fixedly connected to the side of the upright 120 near the side mold 320 of the cable trench. A second sliding seat 124 is slidably sleeved on the surface of the side rod 123. A first lifting system is set between the side rod 123 and the inner mold 310 of the cable trench. A first translation system is set between the second sliding seat 124 and the adjacent upright 120. A second lifting system is set between the side rod 123 and the side mold 320 of the cable trench. A second translation system is set between the bottom rod 110 and the side mold 320 of the cable trench. The sliding cooperation between the side rod 123 and the second sliding seat 124 provides guidance for the lifting and translation of the inner mold 310 and the side mold 320 of the cable trench, so as to realize the precise and controllable movement of the template.

[0037] The first lifting system includes a second hydraulic cylinder 410, which is installed between the side rod 123 and the inner mold 310 of the cable trench; the first translation system includes a fourth hydraulic cylinder 430, which is installed between the second sliding seat 124 and the adjacent upright 120; the second hydraulic cylinder 410 and the fourth hydraulic cylinder 430 are independently controlled to achieve precise three-dimensional positioning of the inner mold 310 of the cable trench, and meet the adaptation requirements of the inner mold of cable trenches with different cross-sections.

[0038] The second lifting system includes a third hydraulic cylinder 420, which is installed between the side rod 123 and the cable trench side mold 320. The second translation system includes a fifth hydraulic cylinder 440, with two fifth hydraulic cylinders 440 installed vertically between the cable trench side mold 320 and the corresponding bottom rod 110. The third hydraulic cylinder 420 and the fifth hydraulic cylinder 440 work together to ensure that the verticality of the cable trench side mold 320 meets the standard. The dual-cylinder design makes the translation force of the cable trench side mold 320 balanced, avoiding uneven deformation of the template.

[0039] Among them, the bottom of the cable trench side formwork 320 near the bottom rod 110 is hinged with a spiral support 500. The other end of the spiral support 500 is provided with an anti-slip support head that can contact the construction base surface. The spiral support 500 uses a T60×8 trapezoidal threaded screw as the main telescopic rod, and the end is adapted to a T80×10 trapezoidal threaded foundation jack as a stable base. It is covered with a seamless steel pipe sleeve to enhance rigidity. The spiral support 500 is reinforced with an external ground anchor. The spiral support 500 provides strong support through the trapezoidal threaded screw and foundation jack structure. The anti-slip support head cooperates with the ground anchor to ensure the forming accuracy of the cable trench side wall and effectively control the bottom displacement of the cable trench side formwork 320.

[0040] The base rod 110 is equipped with a control system 600. The traveling trolley 220, the first hydraulic cylinder 230, the second hydraulic cylinder 410, the third hydraulic cylinder 420, the fourth hydraulic cylinder 430, and the fifth hydraulic cylinder 440 are electrically connected to the control system 600. The control system 600 has a built-in program that can output electrical signals to the traveling trolley 220 and each hydraulic cylinder according to construction parameters (such as template positioning requirements, travel instructions, etc.) to precisely control the extension and retraction stroke and travel speed of the hydraulic cylinders, so as to realize the symmetrical lifting and translation synchronous movement of the side formwork 320 and the inner formwork 310 of the cable trench on both sides.

[0041] The control system 600 consists of a control host, sensor modules, execution modules, and an operator terminal. The control host can be an industrial-grade PLC, such as the Siemens S7-1200 series. The sensor modules include displacement sensors (installed on the piston rods of each cylinder to provide real-time feedback on the extension / retraction stroke), pressure sensors (connected to the hydraulic system 400 to monitor the working pressure of each cylinder), and tilt sensors (installed on the base rod 110 to detect the levelness of the trolley and assist the first cylinder 230 in adjusting the lateral slope). The execution modules are equipped with relay output modules that connect to the solenoid directional valves of each cylinder to control the extension / retraction direction of each cylinder. The drive motor of the traveling trolley 220 controls the traveling speed; the operating terminal adopts a touch screen, which integrates manual and automatic mode switching buttons, parameter setting interface (such as template positioning coordinates, traveling speed) and status display area (real-time display of the stroke and pressure values ​​of each cylinder), which is convenient for on-site operation; the displacement sensor, pressure sensor and tilt sensor of the sensor module are connected to the input terminal of the control host through shielded signal lines, and the output terminal of the control host is electrically connected to the solenoid reversing valve of each cylinder and the drive motor controller of the traveling trolley 220 through the relay output module. The operating terminal is bidirectionally connected to the control host through a communication line.

[0042] The working principle of this utility model is as follows:

[0043] Workstation movement: The control system 600 drives the traveling trolley 220 to move along the track to the construction section, and the first hydraulic cylinder 230 adjusts the height of the support column 210 according to the tunnel cross slope;

[0044] Inner mold positioning: The fourth hydraulic cylinder 430 pushes the second sliding seat 124 to move horizontally along the side rod 123, driving the second hydraulic cylinder 410 and the inner mold 310 of the cable trench to be directly above the lining surface; the second hydraulic cylinder 410 extends and retracts to adjust the height of the inner mold 310 of the cable trench to ensure accurate positioning;

[0045] Side mold positioning: The fourth hydraulic cylinder 440 drives the cable trench side mold 320 to move horizontally and fit the designed side wall position; the third hydraulic cylinder 420 adjusts the height of the cable trench side mold 320 to align it with the top of the cable trench inner mold 310, and the cable trench inner mold 310 and the top of the cable trench side mold 320 are fixed by bolts and nuts.

[0046] Support and reinforcement: Rotate the spiral support 500 hinged at the bottom of the side formwork 320 of the cable trench to make the anti-slip support head press against the construction base surface. Combined with ground anchor reinforcement, a dual stability system of hydraulic cylinder and spiral support is formed to resist the lateral thrust during pouring.

[0047] Concrete pouring: The concrete is poured through the pre-set pouring port of the inner mold 310 of the cable trench, and the self-leveling of the concrete is achieved by utilizing the gaps between the molds. The single pouring is completed quickly. During the pouring process, the hydraulic system 400 monitors the stress on the mold in real time to ensure stable molding.

[0048] Demolding and relocation: After the pouring is completed, the spiral support 500 retracts, and the hydraulic system 400 sequentially drives the oil cylinder to shrink the cable trench side mold 320 and the cable trench inner mold 310, so as to achieve the separation of the template from the concrete surface without damage; the traveling trolley 220 drives the trolley to move to the next station and repeats the above process.

[0049] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
