TECHNICAL FIELD

[0001] The utility model relates to a track-laying lining trolley technical field, especially to a multi-door frame structure automatic track-laying lining trolley. BACKGROUND

[0002] The track-laying lining trolley plays a key role in tunnel engineering construction. It is mainly used for tunnel lining construction and can accurately help construction personnel to complete the pouring of the inner wall concrete of the tunnel, ensuring that the internal structure of the tunnel meets the design standard, and is an important tool for ensuring the strength, stability and internal surface flatness of the tunnel. During the tunnel construction process, it acts as a movable mold and advances along the tunnel at a predetermined pace, enabling the concrete lining construction to be carried out efficiently and orderly.

[0003] The traditional track-laying lining trolley is mainly composed of a frame, a formwork system, a walking system and a support system. The frame is the skeleton of the whole trolley, generally welded from profile steel, providing a stable installation base for other components and ensuring the overall strength of the trolley. The formwork system is the key part, including top and side forms, usually made of steel formwork, combined together by bolt and hinge connection, which can accurately outline the profile of the tunnel lining, with a smooth surface to ensure the lining quality. The walking system is mainly the track wheels installed at the bottom of the frame, which cooperate with the track laid at the bottom of the tunnel, enabling the trolley to move forward or backward smoothly along the track. The support system is composed of various jacks and support rods distributed between the frame and the formwork, used to adjust the position of the formwork, support the weight of the formwork and bear the pressure during concrete pouring, ensuring the stability of the formwork during construction.

[0004] From the structural point of view, the traditional track-laying lining trolley has a large self-weight because its frame is mostly welded from a large number of profile steel to ensure strength to bear the weight of the formwork system, concrete and construction load; the formwork system is made of thick steel plates to ensure the shape accuracy and quality of the lining, which results in a considerable weight of the trolley itself. The track self-propelled type is mostly used because the trolley itself is heavy and bulky, and the track can provide stable support and guidance to ensure the stability of walking. The reason for manually laying steel rails and sleepers during the trolley walking process is that the trolley walking route needs to be continuously extended according to the tunnel construction progress, there is no ready-made fixed track, and the track laying accuracy needs to be ensured to meet the trolley walking requirements. The track needs to be manually aligned and corrected because the construction environment is complex, and the track may be shifted during the trolley movement and concrete pouring process.
