Supporting device for tunnel construction

Abstract

The invention discloses a supporting device for tunnel construction. The supporting device comprises a base, a second adjusting ring and a mounting block. A supporting rod is arranged above the base,an adjusting rod is mounted on the inner side of the supporting rod, a limiting groove is formed in the inner side of the supporting rod, and a limiting rod is mounted on the outer side of the adjusting rod. The adjusting rod is connected with the supporting rod through the limiting rod and the limiting groove, a sleeve rod is mounted above the second adjusting ring, the sleeve rod is located on the outer side of the adjusting rod, a linkage rod is arranged below a supporting rod, and the linkage rod is connected with the supporting rod through a pin shaft. An inserting rod is mounted on a third adjusting ring, the inserting rod is connected with the inserting ring, and the inserting ring is located on the outer side of the supporting rod. The supporting device for tunnel construction canbe conveniently unfolded to be mounted, step-by-step manual welding or riveting is not needed, the mounting efficiency is improved, adjusting is convenient, the supporting device can be finely adjusted according to the specific condition of tunnel construction, and the stability of supporting is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a support device for tunnel construction. Background technique [0002] Tunnel construction usually refers to the excavation of passages in mountains or underground. During tunnel construction, in order to avoid the collapse of the tunnel roof, it is usually necessary to use support devices for support and protection. [0003] Most of the existing supporting devices are composed of bolt welding or riveting, which is inconvenient to adjust, and at the same time, it is inconvenient to install or disassemble, which increases the complexity of installation, prolongs the installation period, and is inconvenient to install and protect in time. In view of the above problems, an innovative design is carried out on the basis of the original support device. Contents of the invention [0004] The purpose of the present invention is to provide a support device for tunnel const...
