Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to an excavation and support operating platform for high-speed tunnel construction. Background Art

[0002] The construction platform is a mobile (wheeled, rail-mounted or skid-mounted) or assembled work frame manufactured to facilitate the construction of excavation, support, waterproof boards, etc. It is generally composed of a gantry, a telescopic (folding) work platform, a wind, water and electricity interface, a lifting equipment, a traveling mechanism, etc. In the process of excavation and support of high-speed tunnel construction, manual pneumatic drills are often used for excavation, and the operating platform is a working platform that facilitates workers to excavate and support.

[0003] A Chinese patent with announcement number CN206655701U discloses a tunnel excavation support gantry, which is convenient for lifting heavy objects, has high reliability and good safety. By installing rollers and a drive device at the bottom of the trolley gantry, independent movement of the gantry is achieved, which is convenient for operation. By opening a through hole on the trolley gantry, the manufacturing cost and weight of the trolley gantry can be reduced, and it is convenient for construction workers to climb through the through hole, which can shorten the process operation time and reduce the process connection time.

[0004] In the above scheme, the size of the gantry is fixed, and the distance between the gantry and the top of the tunnel can be reduced by adding a structure on the top of the gantry. However, the distance between the side of the gantry and the tunnel is difficult to effectively compensate, which makes it extremely inconvenient for workers to install anchor rods and guard plates. To this end, we provide a high-speed tunnel construction excavation support operation platform to solve the above problems. Utility Model Content

[0014] 3) Beneficial effects:

[0015] Compared with the existing technology, the high-speed tunnel construction excavation support operation platform has the following beneficial effects:

[0016] 1. The utility model realizes the dynamic adjustment function of the distance between the side of the workbench and the tunnel wall by arranging two-way cylinders and supporting rods and movable plate structures connected thereto on both sides of the workbench. This design overcomes the problem that the traditional fixed gantry cannot effectively compensate for the side gap, greatly facilitates the operation of workers when performing operations such as anchor rod and guard plate installation, improves work efficiency, and reduces inconvenience and safety hazards in construction.

[0017] 2. The utility model adopts the design of installing the extension plate on the support rod by means of a slot, which not only increases the support stability of the workbench, but also makes the entire frame structure more flexible and adaptable to tunnel environments of different diameters and shapes.
