Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and in particular to a self-propelled hydraulic secondary lining trolley construction device. Background Technology

[0002] In the secondary lining construction of small-section hydraulic tunnels, the traditional method for constructing the secondary lining formwork involves erecting temporary scaffolds and installing temporary formwork such as wooden templates. This traditional method requires erecting scaffolds and splicing formwork, resulting in low construction efficiency, a large workforce, and quality defects such as seams, grout leakage, and honeycomb-like pitting at the spliced ​​joints after concrete pouring. In tunnels with steep longitudinal slopes, the traditional method of erecting scaffolds and installing temporary formwork poses a significant risk of overturning, requiring complex reinforcement measures for the scaffolds. The traditional method fails to guarantee construction quality, safety, and efficiency. Therefore, there is an urgent need for an integrated secondary lining formwork construction device that can reduce manpower consumption while improving the efficiency of secondary lining formwork installation, and enhancing the construction quality and safety of the secondary lining concrete construction process. Utility Model Content

The sidewall template telescopic drive assembly is used to drive the sidewall template to rotate outwards along the arched template. Several template connecting rods are installed between a sidewall template and a corresponding side of the trolley body to fix the position of the corresponding sidewall template.

[0006] Furthermore, the trolley body includes two trolley masts, two bottom longitudinal base beams, several mast columns, several mast longitudinal connecting beams, several mast reinforced cross scissor frames, and a climbing platform; the two trolley masts are arranged longitudinally at intervals along the front-rear direction, and the two bottom longitudinal base beams are fixedly connected parallel to each other between the bottoms of the two trolley masts; several mast longitudinal connecting beams and several mast columns are fixedly connected between the two sides of each trolley mast, the several mast longitudinal connecting beams are arranged parallel to the corresponding bottom longitudinal base beam from top to bottom at intervals, and the several mast columns are perpendicular to the corresponding bottom longitudinal base beam from front to back. The system is designed with spacing between each gantry longitudinal connecting beam and each gantry column on the same side. A gantry reinforcement cross scissor beam is fixedly connected between each pair of adjacent gantry columns on the same side. Each gantry reinforcement cross scissor beam has its two sides fixedly connected to a gantry column, and its middle section fixedly connected to the same gantry longitudinal connecting beam. Two ladder platforms are provided, each fixedly connected to a trolley gantry. Each trolley gantry has a support leg at its bottom on both sides, and the support leg is a lifting hydraulic jack.

[0007] Furthermore, each of the support legs also includes a lateral adjustment support base and a lateral translation hydraulic jack at its bottom. The bottom of each support leg is slidably connected to the corresponding lateral adjustment support base via a slide rail. One end of the lateral translation hydraulic jack is hinged to the lateral adjustment support base, and the other end of the lateral translation hydraulic jack is hinged to the bottom of the corresponding support leg.

[0008] Furthermore, the trolley movable slide includes two movable slides and a connecting shaft.

[0013] The beneficial effects of this utility model are:

[0014] 1) This utility model uses several vertically retractable support legs to enable the main body of the platform to lift and lower. Combined with a moving drive component, this allows the trolley to move automatically. When the support legs retract, the main body of the platform descends, allowing the bottom of the trolley's sliding seat to contact the ground until the support legs are completely suspended in the air. This allows the trolley's sliding seat to support the main body of the platform. At this point, driven by the moving drive component 22, the main body of the platform slides relative to the trolley's sliding seat, traveling a certain distance relative to the ground. Afterward, the support legs extend, lifting the main body of the platform and causing the bottom of the trolley's sliding seat to lift off the ground, completing the movement. One automatic movement, continuously repeating the above actions, can continuously move the main body of the trolley to the construction position. After reaching the construction position, the support legs extend to lift and position the main body of the trolley. Adjusting the trolley axis and elevation completes the positioning of the arch formwork. Then, the side wall formwork is flipped outwards into place by the side wall formwork telescopic drive component. The side wall formwork is positioned and fixed by the formwork connecting rod. The lining formwork installation is completed quickly, reducing the splicing problem of traditional wooden formwork, reducing construction time, reducing manpower consumption, reducing safety risks, and improving construction efficiency.

[0015] 2) Simultaneous pushing of four lateral hydraulic jacks in one direction can offset the entire platform body along the four lateral adjustment supports, thereby adjusting the position of the trolley body along its axis, reducing the adjustment time of the platform body, and improving work efficiency.

[0016] 3) After the side wall formwork is flipped into place, the formwork connecting rod can be used to support and fix the position of the side wall formwork. By adjusting the relative position of the screw and the threaded connecting cylinder, the overall length of the formwork connecting rod can be adjusted to meet different construction needs.

The hydraulic walking mechanism 2 is installed on both sides of the bottom of the trolley body 1, and each hydraulic walking mechanism 2 includes a trolley sliding seat 21 and a moving drive assembly 22.

The inner side of each side wall template 32 is hinged to one end of a side wall template telescopic drive assembly 33, and the other end of the side wall template telescopic drive assembly 33 is hinged to the corresponding side of the trolley body 1. The side wall template telescopic drive assembly 33 is used to drive the side wall template 32 to rotate outward along the arched template 31. Several template connecting rods 34 are installed between a side wall template 32 and the corresponding side of the trolley body 31 to fix the position of the corresponding side wall template 32. This invention utilizes several vertically retractable support legs to enable the platform body to rise and fall.

Afterward, the support legs extend, lifting the platform body and causing the bottom of the trolley's sliding seat to leave the ground, completing one cycle of automatic movement. By continuously repeating the above actions, the main body of the trolley can be automatically moved to the construction position. After reaching the construction position, the support legs extend to lift and position the main body of the trolley. The axis and elevation of the main body of the trolley are adjusted to complete the positioning of the arch formwork 31.
