Description

Technical Field

[0001] The utility model belongs to the technical field of supporting devices, in particular to an auxiliary supporting device for tunnel construction equipment. Background Art

[0002] With the development of underground engineering construction, efficient mechanized operation equipment has emerged in tunnel engineering construction. Tunnel engineering equipment generally has the characteristics of heavy weight and high center, and there is a problem of insufficient stability during operation. During tunnel engineering construction, the tunnel side wall or ground where the equipment works has the characteristics of unevenness and low compressive strength. Ordinary rigid support is used, and the support stability decreases due to the depression of the ground or tunnel wall as the equipment working load changes.

[0003] In the existing open document CN214275012U, an auxiliary support device for tunnel construction equipment is disclosed. By adding auxiliary support to the tunnel equipment, the stability of the tunnel construction equipment is increased, the stable working needs of the tunnel construction equipment are met, and the equipment safety and construction efficiency are improved. The utility model is suitable for auxiliary support of underground engineering construction equipment such as tunnel railways, highways, subways, underground fortifications, water diversion tunnels, mine shafts, etc. The lateral adjustment telescopic sleeve can be adjusted lateraly under the action of the lateral adjustment cylinder, the support cylinder can adjust the position of the support shoe, and the yaw cylinder can adjust the support angle, thereby realizing multi-directional adjustment, and the tunnel equipment can be auxiliary supported on the tunnel side wall or the ground.

[0004] However, the existing support assembly structure has multiple sections, and each section is fixed and connected to each other by bolts or rivets. However, the height and lateral width of the tunnels are different. If the support assembly is required in tunnels of different sizes, the user needs to disassemble and assemble it again, which brings inconvenience to the use and adjustment on site. To this end, we provide an auxiliary support device for tunnel construction equipment to solve the above problems. Utility Model Content
