Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a tunnel lining trolley surface oiling device and a tunnel lining trolley. Background Art

[0002] In tunnel construction, secondary lining is an important part of the tunnel structure, and its quality directly affects the overall stability and safety of the tunnel. As a key equipment in the construction process, the surface treatment of the formwork of the tunnel lining trolley is crucial to ensure the flatness and finish of the concrete lining. In order to prevent the steel formwork from rusting, reduce friction during concrete pouring, improve the surface finish and flatness of the concrete, and ensure smooth demoulding, oiling technology, as an important means of formwork surface treatment, is widely used in the maintenance of the formwork of the tunnel lining trolley.

[0003] At present, the oiling and maintenance of the surface of tunnel lining trolleys is mainly done manually, but the manual operation efficiency is low. In addition, the tunnel lining trolley is located in a drill-and-blast tunnel with a narrow working environment. Manual application is extremely inconvenient, and there are blind spots in the construction, resulting in high work intensity.

[0004] In order to solve the above problems, the existing technology also provides a variety of solutions, but there are still some shortcomings, such as:

[0005] Patent CN209393437U discloses an automatic grinding and oiling device for a tunnel lining trolley panel, which includes a track frame matched with the tunnel lining trolley panel, a grinding and oiling vehicle and two winches. The grinding and oiling vehicle is driven by a winch to slide along the track, one ring is one cycle, and the grinding and oiling width of each cycle is about 430mm of the track frame width. Therefore, it is necessary to move the lining trolley 400mm every time a cycle is completed to ensure the grinding and oiling of the entire lining trolley panel. The work efficiency is slow and the distance is difficult to control; Patent CN109365339B discloses a large-section tunnel lining trolley template annular automatic cleaning and coating construction device and method, including: annular steel guide rails, annular traction equipment, cleaning and coating equipment and pipeline systems; after the device is installed in place, the strong and weak electric cables transmit power and control signals, the control command starts the cleaning motor to start the wire brush, and at the same time starts the annular traction equipment to drive the cleaning and coating equipment to move along the annular steel guide rail to achieve one ring of cleaning, and then the infrared recognition sensor is used to sense, and the spraying controller controls the spray agent nozzle to complete the spraying; after completing one ring, the lining trolley is pushed forward, and the advancement distance recorded by the infrared recognition sensor is transmitted to the cleaning controller to start the cleaning and coating of the next ring. The whole process is complex to control, and the movement is intermittent, so the efficiency is low. Patent CN114278340A discloses a composite tunnel lining trolley release agent and its preparation method and application. The release agent is applied to the outer surface of the tunnel lining trolley template by a coating mechanism. The coating mechanism includes a mounting frame and a spraying mechanism. The mounting frame includes legs connected to mounting holes evenly arranged at both ends of the template body and racks detachably connected between the legs. There is a liquid storage tank on the spraying mechanism. Driven by the gear, the spraying mechanism moves along the rack on the mounting frame to achieve radial spraying of the lining trolley. However, to achieve the spraying of the entire panel, the coating mechanism needs to be disassembled and assembled at different mounting holes of the template body, which affects the construction efficiency. In short, the existing spraying mechanism cannot achieve the continuous and rapid completion of the oiling of the entire lining steel mold surface in a narrow space, and it is inconvenient to disassemble and assemble, has poor flexibility, and low work efficiency.

[0006] Therefore, it is urgent to develop a tunnel lining trolley surface oiling device to improve the oiling efficiency and oiling effect and meet the needs of tunnel lining trolley steel film maintenance during tunnel construction. Summary of the invention

[0037] See also Figure 3 The oiling drag chain in the oiling drag chain assembly 4 of the present invention is arranged along the width direction of the tunnel lining trolley 1 and spans the entire width of the tunnel lining trolley 1, so that the entire surface of the tunnel lining trolley 1 can be sprayed in one spraying, thereby improving the oiling efficiency. The oiling drag chain has the same curvature as the surface of the tunnel lining trolley 1, which can improve the uniformity of the oiling. The oiling drag chain can be made of a bendable material, or a long drag chain formed by hinged connection of multiple single-section drag chains 4-1 to match the curvature of the surface of the tunnel lining trolley 1, so that all nozzles 6-5 on the oiling drag chain are at the same distance from the surface of the tunnel lining trolley 1, thereby ensuring the uniformity of the oiling.
