[0018] First embodiment

[0019] See also Figure 1 to Figure 3 , Figure 1 is a front view of a trackless trolley according to a first embodiment of the present invention, Figure 2 1 is a diagram showing the positioning state of the trackless vehicle according to the first embodiment of the present invention. Figure 3 It is a demoulding and walking state diagram of the trackless trolley according to the first embodiment of the present invention.

[0020] The present invention provides a trackless trolley: including a formwork mechanism, a support mechanism, a walking system, a hydraulic system 110, a material distribution system 111, a vibrating system 112 and a platform ladder, the formwork mechanism includes a top formwork 101, a side formwork 102 and a bottom formwork 103, the support mechanism includes an upper arch frame 104, a main door frame 105 and a side formwork support 106, the walking system includes a walking motor 107, a steering motor 108 and a walking wheel 109, and the platform ladder includes a top platform 113, a ladder 114 and a guardrail 115. The above-mentioned solution solves the problem that the above-mentioned secondary lining trolley cannot realize the actions of erecting, closing, advancing and turning according to actual use requirements, resulting in a reduction in the actual use effect of the secondary lining trolley. It can be understood that the above-mentioned solution can be used in the scenario of secondary lining construction in tunnel construction.

[0021] In this embodiment, through the coordinated use of the formwork mechanism, the support mechanism, the walking system, the hydraulic system 110, the material distribution system 111, the vibration system 112 and the platform ladder, the actions of erecting, closing, advancing and turning can be realized according to actual use requirements during the use of the trackless trolley, thereby improving the actual use effect of the second lining trolley, solving the technical problem that the existing second lining trolley cannot realize the actions of erecting, closing, advancing and turning according to actual use requirements, resulting in a reduction in the actual use effect of the second lining trolley. At the same time, the overall formwork adopts the retractable hydraulic system 110, and the lining surface has a high flatness.

[0022] The supporting mechanism is used to support the formwork mechanism, the walking system and the hydraulic system 110 are both located below the formwork mechanism, the walking system is used to drive the formwork mechanism to walk, the hydraulic system 110 is used to lift the formwork mechanism, the material distribution system 111 is used to pour concrete, the vibrating system 112 is used to vibrate concrete, the platform ladder is located outside the formwork mechanism, so that the staff can put concrete into the material distribution system 111, the material distribution system 111 includes a layered distributor, a top feed port, a left feed port and a right feed port, the The layered distributor delivers concrete to the top feed port, the left feed port and the right feed port respectively. The concrete is pumped to the top of the trolley through the main pipe by the vehicle-mounted pump and enters the hopper. The concrete is separated by the hopper and then flows into the windows of each level through the grouting port 116. The top holes of the arch are arranged separately, and a total of 18 casting windows are set. The concrete pouring is carried out in the form of layer-by-layer distribution and window-by-window vibration. The vibration system 112 is mainly composed of a vibrator and a control cabinet. The whole trolley is equipped with 12 flat-plate vibrators (3 in 1 column, and 4 in total on the left and right sides). Each group of systems is independent of each other and does not affect each other.

[0023] Secondly, the side formwork 102 is arranged on the bottom formwork 103 , and the top formwork 101 is arranged on the bottom formwork 103 and is located inside the side formwork 102 .

[0024] Again, the upper arch frame 104 is arranged between the side formwork 102 and the top formwork 101, the main portal 105 is arranged on the bottom formwork 103 and under the top formwork 101, and the side formwork support 106 is arranged between the upper arch frame 104 and the main portal 105. The upper arch frame 104 mainly supports the top formwork 101 to ensure the rigidity of the top formwork 101 and transfers the force of the top formwork 101 to the main portal 105. The main portal 105 has a strong bearing capacity and is the main force-bearing structure, which bears all forces from the top formwork 101 or the side formwork 102. The side formwork support 106 supports the side formwork 102, bears the lateral force from the side formwork 102, and transfers it to the main portal 105.

[0025] In addition, the travel motor 107 and the steering motor 108 are respectively used to drive the travel wheel 109 to travel or turn. The travel wheel 109 is arranged under the main gantry 105. The trackless trolley is equipped with 4 sets of the travel motors 107 and 2 sets of the steering motors 108. The power of the travel motor 107 is 3kW, and the power of the steering motor 108 is 2.2kW. At the same time, the trackless trolley is equipped with 4 sets of braking systems, which will brake after the trolley walks to the specified position to prevent the trolley from slipping during work.

[0026] Finally, the top platform 113 is arranged outside the main portal 105, and the guardrail 115 and the ladder 114 are respectively arranged on the upper and lower sides of the top platform 113. Through the coordinated use of the top platform 113, the guardrail 115 and the ladder 114, the workers' work needs can be facilitated to the greatest extent and the workers' high-altitude operation safety can be guaranteed.

[0027] When using the present invention, the travel motor 107 and the steering motor 108 are operated to make the trolley travel to the section to be lined. Then, the travel wheel 109 is suspended by operating the lifting cylinder of the hydraulic system 110. Then, the translation cylinder of the hydraulic system 110 is operated to adjust the center line of the trolley so that the trolley is aligned with the center line of the tunnel. Subsequently, the lifting cylinder of the hydraulic system 110 is operated to raise the trolley to the standard lining height. Then, the foundation jack is tightened. After that, the height dimension is checked. Then, the hydraulic system 110 is operated again to raise the hydraulic system 110 to the standard lining height. The lateral cylinder piston rod extends out and reaches the standard lining section, then the lateral support screw jack is manually turned to make it reach the lateral cylinder support position and tightened. After completing the above actions, the section size should be reviewed to prevent errors. Finally, the concrete is pumped to the top of the trolley through the main pipe by the vehicle-mounted pump and enters the hopper. The concrete is separated by the hopper and then flows into the windows of each level through the grouting port 116 and is vibrated by the vibration system to realize the use of the trackless trolley, so that both sides of the tunnel can be poured during the secondary lining construction of the tunnel.

[0028] To sum up, through the coordinated use of the formwork mechanism, the supporting mechanism, the walking system, the hydraulic system 110, the material distribution system 111, the vibration system 112 and the platform ladder, the actions of erecting the formwork, closing the formwork, advancing and turning can be realized according to actual use requirements during the use of the trackless trolley, thereby improving the actual use effect of the second lining trolley, and solving the technical problem that the existing second lining trolley cannot realize the actions of erecting the formwork, closing the formwork, advancing and turning according to actual use requirements, resulting in a reduction in the actual use effect of the second lining trolley. At the same time, the overall formwork adopts the retractable hydraulic system 110, and the lining surface has a high flatness.
