Description

Technical Field

[0001] This utility model relates to a modular tunnel lining trolley, and more particularly to a modular tunnel lining trolley used in the field of tunnel construction equipment. Background Technology

[0002] A tunnel lining trolley, or simply a "trolley," is a large, specialized, mobile formwork device used in the construction of underground engineering projects such as tunnels, subways, and hydraulic culverts. After tunnel excavation and initial support are completed, the trolley is positioned to provide a molded template system for pouring the final, permanent reinforced concrete lining of the tunnel's inner wall. This determines the final internal contour, dimensions, flatness, and strength of the tunnel.

[0003] The existing tunnel lining trolleys are quite long, making it difficult to make turns when moving to larger bends in the tunnel, which causes considerable inconvenience to the workers. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that, during the construction of tunnel lining trolleys in tunnels, due to the long length of the existing tunnel lining trolleys, it is difficult to make turns when moving to large bends in the tunnel, which causes great inconvenience to the personnel during tunnel construction.

[0005] To solve the above problems, this utility model provides a combined tunnel lining trolley, including a walking system. The top of the walking system is fixedly connected to a lower longitudinal beam by bolts, and a lifting cylinder is provided on the top of the lower longitudinal beam.

[0006] A side mold cylinder is provided on the top of the lifting cylinder, and a gantry assembly is fixedly connected to the top of the side mold cylinder. A template connecting beam is provided above the gantry assembly.

[0007] The top of the gantry assembly is fixedly connected to an upper longitudinal beam, and an upper platform is fixedly connected to the side of the upper longitudinal beam away from the gantry assembly. Several small columns are fixedly connected to the top of the upper platform, and a gantry connecting beam is provided on the side of the gantry assembly.

[0008] The template assembly is fixedly connected to the side of the template connecting beam, several side mold screws are provided on the lower longitudinal beam, a travel cylinder is provided between the travel systems, and a scissor frame is fixedly connected to the gantry assembly.

[0009] As another improvement of this application, the walking system is fixedly connected to a mounting plate via a threaded block. A miniature air pump is provided on the mounting plate. A vertical pipe is fixedly connected to the air outlet of the miniature air pump. A sleeve is fitted at the bottom end of the vertical pipe. A connecting frame is fixedly connected at the bottom end of the sleeve. An inflation plate is fixedly connected to the inner top wall and a pair of inner side walls of the connecting frame. A wiping plate is fixedly connected to the side of the inflation plate.

[0010] As a further improvement to this application, the vertical pipe is provided with several limiting grooves, and the sleeve is threadedly connected with a threaded block.

[0011] As a further improvement to this application, both the first threaded block and the second threaded block are fixedly connected with a disassembly block. The outer side of the disassembly block is engraved with anti-slip texture. In the initial state, one end of the second threaded block is threaded into the inside of the limiting groove.

[0012] As a further improvement to this application, a pair of symmetrically distributed vertical grooves are provided on the inner wall of the sleeve, and a pair of sliders that are slidably connected to the outside of the vertical tube are fixedly connected to the vertical grooves.

[0013] As a further improvement to this application, both the vertical groove and the inner wall of the sleeve are provided with sealing grooves, and a sealing ring is fixedly connected inside the sealing groove.

[0014] As a further improvement to this application, the top of the mounting plate is fixedly connected to an internal threaded ring, the internal thread of which is connected to a threaded cover, and the top of the threaded cover is fixedly connected to a filter cover.

[0015] This application has the following beneficial effects when used:

[0016] 1. When in use, this application can assemble two tunnel lining trolleys together according to the construction needs of personnel, or disassemble a long tunnel lining trolley into two short tunnel lining trolleys, thereby ensuring the smooth progress of turning construction. Moreover, the disassembly and assembly steps are simple and convenient for personnel to use, thus ensuring construction efficiency while ensuring construction quality.

[0017] 2. In use, the mounting plate can be installed on the traveling system using the threaded block, so that the wiping plate is located on the rails of the moving trolley. When the trolley moves forward, the wiping plate can wipe the rails in contact with the traveling system, thereby reducing the friction on the traveling system and improving the cleanliness of the traveling system. At the same time, it can also clean foreign objects attached to the rails. The micro air pump can be started to inflate the vertical pipe with air from its outlet. The air passes through the vertical pipe, sleeve pipe and connecting frame in sequence into the inflatable plate, thereby inflating the inflatable plate and pushing the wiping plate to apply pressure to the rails, increasing the wiping force and further improving the cleaning effect of the rails.

[0027] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figure 1-3 A combined tunnel lining trolley is shown, including a walking system 1, the top of which is fixedly connected to a lower longitudinal beam 2 by bolts, and a lifting cylinder 3 is provided on the top of the lower longitudinal beam 2.

[0030] The top of the lifting cylinder 3 is provided with a side mold cylinder 4, and the top of the side mold cylinder 4 is fixedly connected with a gantry assembly 5. A template connecting beam 6 is provided above the gantry assembly 5.

[0031] The top of the gantry assembly 5 is fixedly connected to an upper longitudinal beam 7, and an upper platform 8 is fixedly connected to the side of the upper longitudinal beam 7 away from the gantry assembly 5. Several small columns 9 are fixedly connected to the top of the upper platform 8, and a gantry connecting beam 10 is provided on the side of the gantry assembly 5.

[0032] The template connecting beam 6 is fixedly connected to the template assembly 11 on its side, the lower longitudinal beam 2 is provided with several side mold screws 12, the walking system 1 is provided with walking cylinders 13, and the gantry assembly 5 is fixedly connected with scissor frames 14.

[0033] The installation of this application involves the following steps:

[0034] Step 1: Installation of the traveling parts. First, support the four sets of traveling systems 1 and the lifting mechanism on the rail surface. Then, install the two lower longitudinal beams 2 on the traveling system 1 and support them stably. The four corner support points of the trolley must be on the same horizontal line. After that, tighten the bolts and adjust the diagonal dimensions.

[0035] Step 2: Installation of the gantry. When installing the gantry, first assemble each column and beam on the ground according to the specifications of each frame, install the diagonal supports, and then hoist them onto the two lower longitudinal beams 2 in sequence. Each frame is connected by a longitudinal connecting beam and a diagonal scissor frame 14, and welded at the intersection of the two scissor frames 14. Then adjust the dimensions according to the drawings and tighten the bolts of each part.

[0036] Step 3: Installation of the upper and middle longitudinal beams. Hoist the middle longitudinal beam to the midpoint of the crossbeam and tighten the bolts. Then hoist the upper longitudinal beams 7 on both sides and measure the distance between the two diagonals to ensure consistency. Weld stop blocks to prevent displacement during later installation. Only after the stop blocks are welded can the upper frame 8 be installed.

[0037] Step 4: Installation of the upper platform 8. According to the general assembly drawing, hoist the crossbeams of the upper platform 8 onto the upper longitudinal beam 7 in the specified order and tighten all the bolts. Then install the small columns one by one onto the crossbeams of the upper platform 8 in the specified order and tighten the bolts.

[0038] Step 5: Template Installation: The trolley template is divided into upper template and lower template. For the installation of the upper template, first determine the position of the upper template according to the template installation drawings. After that, hoist the first template (large template) onto the upper frame 8 and screw on the bolts. After initial tightening, hoist the second template. First, put on the connecting bolts of the middle connecting plate. After the bolts of the column and beam are put on, tighten the connecting bolts of the middle connecting plate and then tighten the bolts of the column and beam.

[0039] Install the lower template, paying attention to the position of the working window. First, hoist the middle template on both sides, align the hinge holes with the corresponding hinge holes of the upper template, insert the connecting pin, and then hoist the template connecting beam 6 onto the connecting plate inside the template. Tighten the bolts. Hoist the remaining templates from the middle to both sides according to the distribution position of the working window, adjust the joints between each template, and tighten the bolts.

[0040] Step Six: Installation of the work platform. Assemble the longitudinal beams and diagonal supports of the work platform and fasten them to the cross beams and columns with bolts. Then, hoist the guardrails onto the longitudinal beams and tighten the bolts. Connect the upper end of the ladder to the work platform and tighten it.

[0041] Step 7: Installation of the hydraulic system. Install the oil cylinders in place according to the specifications and drawings. Hoist the hydraulic station to the work platform and position it. Assemble all the valves. Arrange the oil pipes flat and connect them tightly to the oil cylinders, hydraulic station and valves with hydraulic hoses.

[0042] Step 8: Installation of mechanical jacks and end plates: Connect one end of the lateral jack and the ground jack to the hinge lug according to the specifications, and install them to the corresponding hinge lug seats with connecting pins; connect the other end of the lateral jack to the hinge lug, and install them to the corresponding hinge lug seats of the template connecting beam 6 with connecting pins; support the other end of the ground jack on the ground; connect the end plates one by one to the template panels at both ends of the trolley with bolts, thus completing the entire installation process. When connecting and assembling the two short trolleys together, simply remove the two middle walking system 1 sliding sleeves and lift them up, and then replace the extended hydraulic cylinder to assemble the two short trolleys together.

[0043] In summary, when used, this application allows for the assembly of two tunnel lining trolleys together or the disassembly of a long tunnel lining trolley into two short tunnel lining trolleys according to the needs of personnel construction, thereby ensuring the smooth progress of turning construction. Moreover, the assembly and disassembly steps are simple and easy for personnel to use, thus ensuring both construction efficiency and construction quality.

[0044] Second implementation method:

[0045] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0046] Figure 4-7 The walking system 1 is shown to be fixedly connected to a mounting plate 16 via a threaded block 15. A miniature air pump 17 is mounted on the mounting plate 16. A vertical pipe 18 is fixedly connected to the air outlet of the miniature air pump 17. A sleeve pipe 19 is fitted onto the bottom end of the vertical pipe 18. A connecting frame 20 is fixedly connected to the bottom end of the sleeve pipe 19. An inflation plate 21 is fixedly connected to the inner top wall and a pair of inner side walls of the connecting frame 20. A wiping plate 22 is fixedly connected to the side of the inflation plate 21.

[0047] The vertical tube 18 is provided with several limiting grooves 23, and the sleeve tube 19 is threadedly connected with a threaded block 24. In use, the sleeve tube 19 can be moved up and down to move the wiping plate 22 together to adjust the height of the wiping plate 22. After adjustment, the sleeve tube 19 can be fixed by the threaded block 24.

[0048] Both the first threaded block 15 and the second threaded block 24 are fixedly connected with disassembly blocks. The outer side of the disassembly blocks is engraved with anti-slip texture. In the initial state, one end of the second threaded block 24 is threaded into the inside of the limiting groove 23.

[0049] The inner wall of the sleeve 19 is provided with a pair of symmetrically distributed vertical grooves 25, and the outside of the vertical tube 18 is fixedly connected with a pair of sliders 26 that are slidably connected to the vertical grooves 25.

[0050] Both the vertical groove 25 and the inner wall of the sleeve pipe 19 are provided with sealing grooves, and a sealing ring 27 is fixedly connected inside the sealing groove to prevent the sleeve pipe 19 from leaking air.

[0051] The top of the mounting plate 16 is fixedly connected to an internal threaded ring 28, and the internal thread of the internal threaded ring 28 is connected to a threaded cover 29. The top of the threaded cover 29 is fixedly connected to a filter cover 30. In use, the threaded cover 29 needs to be installed on the internal threaded ring 28 to cover the miniature air pump 17 for protection. The filter cover 30 facilitates ventilation inside the threaded cover 29 and filters dust and foreign objects in the air.

[0052] This solution allows for the following: During use, the mounting plate 16 can be installed on the traveling system 1 using the threaded block 15, positioning the wiping plate 22 on the rails of the moving trolley. As the trolley moves forward, the wiping plate 22 wipes the rails in contact with the traveling system 1, reducing friction and improving cleanliness. It also removes foreign matter adhering to the rails. Furthermore, the micro air pump 17 can be activated to inflate the vertical pipe 18, allowing the gas to pass sequentially through the vertical pipe 18, the sleeve pipe 19, and the connecting frame 20 into the inflatable plate 21. This inflates the plate and pushes the wiping plate 22 to apply pressure to the rails, increasing the wiping force and further improving the cleaning effect.
