Three-lane highway lining trolley features

  1. Higher recycling rate: The gantry system, running system, support system, electrical system and hydraulic system of a set of trolleys can be increased from one original to several times.
  2. Faster assembly speed: A large number of pin connections are used instead of bolt connections, and the assembly efficiency is increased by 30%.
  3. Faster delivery speed: Pre-production can be achieved, and the delivery speed is shortened from 30 days to 7 days.
  4. Higher installation accuracy and strength: Standardized production, higher precision pin joint structure, a large number of replacement steel structures in the skeleton support system with pipe structure, ensuring a higher degree of installation dimensional accuracy and a more stable force. structure.

Three-lane highway lining trolley construction

Available in hydraulic and mechanical versions. Compared with the hydraulic type of the frame, the rigidity request is low, the structure type is sensitive, the weight is light, the request for the processing request and the laying trajectory in the construction is low, and the use is convenient, but the hydraulic cylinder has high self-locking request, and the hydraulic cylinder in the lining is not Allow retraction. The mechanical type is the opposite. Because one motor drives several screw drives, the coaxiality of each drive shaft is high, and the frame must have a large rigidity and accurate structure. Due to the heavy structure and high processing requirements, Moreover, since the lead screw is synchronized, when the track elevation error is large, it will directly affect the orientation of the template, and then affect the quality of the lining. After the analysis and comparison, the hydraulic transmission plan is adopted, and the hydraulic cylinder adopts hydraulic lock and balance valve to make the hydraulic cylinder self-locking; the supporting screw structure is used for mechanical determination, and the support of the template is strengthened to ensure that the template does not return when lining Shrink, no deformation. Practice has proved that the lining trolley is hydraulically reasonable and is the development direction.

Three-lane highway lining trolley frame structure optimization

The Three-lane highway lining trolley uses hydraulic transmission to simplify the structure of the frame and reduce the weight. It also improves the sensitivity and diversity of the structure. Through the analysis and comparison of various frame structures, strength calculation and optimization, 9m is selected. The four-frame 12m main gantry construction plan has a structural weight reduction of more than 40% compared to the mechanical type, and the manufacturing cost is reduced by more than 25%. The steel mold steel mold is the working equipment of the trolley. The surface quality and the dimensional accuracy directly determine the quality of the concrete lining. Together, it is the most difficult part to process. It has developed reasonable processing and welding technology, and plans and processes the special assembly welding tire. The mold is used to ensure the accuracy of the overall shape, minimize the welding deformation, ensure the surface surface lubrication, no high and low defects. In order to control the wrong table of the adjacent template, the stabilizing pin of the interference cooperation is used to fix the connecting plate of the adjacent template into one body, and it is useful to control the misalignment of the adjacent template caused by the gap of the bolt hole. After successfully handling the above problems, the quality of the lining is ensured.

Determination of bearing orientation

The full quality of the lining concrete is transmitted to the supporting structure by the trolley steel mold and then transmitted to the gantry. The lining concrete is in a solid-liquid state, with large straight pressure and lateral pressure on the top and side, and a large buoyancy occurs together. When the buoyancy exceeds the straight pressure and the weight of the trolley, the trolley will be in a floating state. Will not work properly. In order to deal with this technical problem, careful calculation, optimization planning, and reasonable selection of each bearing orientation. That is, the lower longitudinal beam on the inner side of the gantry is supported on the ground to prevent the side pressure from advancing the gantry column, and there are several horizontal supports at the outer side of the gantry and the side mold longitudinal beam, at the upper frame and the upper longitudinal beam of the gantry A number of straight supports are used (the top hydraulic cylinders are placed at the top of the two gantry, and the straight support screws are placed in the middle), which are evenly distributed in the longitudinal direction of the trolley. The hydraulic cylinder is determined by hydraulic lock, and the supporting screw is used for mechanical determination to ensure that the hydraulic cylinder does not retract during the lining construction, and the template is not deformed.

Three-lane highway lining trolley is the construction equipment for pouring the secondary lining concrete of the tunnel. It cooperates with other auxiliary machinery, which can reduce the labor force, improve the mechanization efficiency of the tunnel second lining construction, improve the construction progress, and has low input cost, firm structure and convenient operation. The advantages of the tunnel forming surface are different. According to the different tunnel engineering, the lining trolley is divided into a side arch type, a straight wall variable section side arch type, a mutant face type, a full round needle beam type, a full circle walking type and the like. According to the actual needs of users, it can be selected by mobile hydraulic self-propelled, full hydraulic drag type, mechanical steel formwork, simple combination formwork, etc. The length of the trolley can be selected according to the length of the tunnel and the construction period of 6 meters, 9 meters, 10.5. Meter, 12 meters, etc.
