The invention provides an internal-connected needle beam lining trolley. The lining trolley comprises a formwork assembly, a needle beam assembly, a riding wheel group and a guide wheel group, wherein the formwork assembly comprises a bottom formwork, a left formwork, a left top formwork, a right top formwork and a right formwork; the bottom formwork, the left formwork, the left top formwork, the right top formwork and the right formwork are of arc structures, and are connected sequentially end to end to form a closed ring shaped structure; the needle beam assembly comprises a top plate, a left plate, a bottom plate and a right plate; the top plate, the left plate, the bottom plate and the right plate are sequentially connected end to end to form a hollow structure; chamfers are formed at two ends of the top plate; two ends of the bottom plate are respectively arranged on the bottom formwork through the riding wheel group and the guiding rail group; a spacing screw rod is arranged on the riding wheel group; vertical connecting beams are arranged in parallel on the bottom plate; a top tilting formwork supporting part is arranged on the formwork assembly; a top horizontal formwork supporting part is arranged between the formwork assembly and the needle beam assembly; and a bottom formwork supporting part is arranged between the formwork assembly and the riding wheel group. By applying the internal-connected needle beam lining trolley, the whole structure is concise, the structure is compact, the clearance is large, parts can be saved, and cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to an inner-through needle beam lining trolley. Background technique [0002] At present, in the construction of tunnels such as water diversion tunnels, in order to ensure the quality of the lining and reduce the construction period, the bottom arch, side wall, and top arch are usually formed through the entire section at one time during the lining, and needle beam trolleys are generally used for lining. In this case, the lining operation can only be carried out after the excavation is completed and the tunnel is fully penetrated. When the construction period is relatively tight and the surrounding rock is poor, lining and excavation operations need to be carried out at the same time, that is, excavation of the front chamber and lining of the rear trolley. The needle beam trolley must be able to meet the needs of large engineering vehicles (such as loaders, e...
