Abstract

The invention provides a multifunctional tunnel arch bracket operating trolley, which comprises a gantry system, an arch bracket adjusting device, and arch bracket adjustment top tightening device. The multifunctional tunnel arch bracket operating trolley is characterized that the multifunctional tunnel arch bracket operating trolley has effects of the simple overall structure; the gantry system comprises an upper gantry and a lower gantry, and the upper gantry and the lower gantry can be extended and contracted relative to each other to adjust the height of the whole gantry system, so that the multifunctional tunnel arch operating trolley can meet operation in tunnels with a variety of cross-section sizes, so the universality is high; the combination of the arch bracket adjusting device and the arch adjustment top tightening device can adjust the arch bracket to a corresponding installation position, can realize the quick and accurate installation of the arch bracket, decreases laborintensity, and increases efficiency; and the arch bracket adjustment top tightening device comprise a plurality of adjustable lateral platforms, which not only can serve as operating platforms for manual pneumatic rock drills but also can meet arch bracket installation operations of a variety of construction methods for the same tunnel such as full-section, two-step and three-step excavation, so the multifunctional tunnel arch bracket operating trolley is high in universality, and can be repetitively utilized, reducing cost.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a multifunctional tunnel arch operation trolley. Background technique [0002] The tunnel excavation is designed according to the tunnel surrounding rock grade and other conditions. In order to ensure the safety of the construction, it is necessary to do the initial support in time after the excavation. Arch support is often used for the initial support of tunnel engineering. Existing arch work trolleys can lift and transport the arch to a specific location, but specific arch work trolleys can only cope with specific tunnel section sizes and specific section excavations The existing tunnel excavation methods mainly include full-section, two-step and three-step, etc. The existing arch operation trolley can only adapt to one excavation method, and can only adapt to a specific tunnel section size, which makes the existing The arch work trolley has too many limitations, ...
