Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and in particular relates to a semi-automatic operating platform for dismantling and transporting rails in a shield tunnel. Background Art

[0002] As shield engineering construction technology continues to mature, the investment in automated machinery has become particularly important for the construction industry. Various industries are paying more attention to replacing manual labor with mechanization to improve work efficiency. How to ensure construction safety during shield construction while completing construction tasks more conveniently and efficiently is a huge challenge facing companies.

[0003] At present, after the shield machine excavation is completed, a large number of rails laid in the tunnel need to be removed in time. In addition, the distance between the tunnels is long, there are multiple sections to switch, the time is tight, the task is heavy, and the weight of a single rail is large. The conventional removal method requires multiple personnel to collaborate in removal, shift handling, and loading, so rail removal is particularly important and cumbersome. Moreover, the removal and transportation process requires a large amount of rails to be removed, the interval is long, the efficiency is low, the cost is high, it is laborious and time-consuming, and there are also major safety hazards.

[0004] At present, conventional transport platforms are usually used for rail removal in tunnels. The platform uses the front of a battery car as a driving force and is connected to an operating platform for site transportation. For example, a Chinese patent (CN210134301U) discloses a lifting and moving device for rail removal. The device only has basic operating functions and cannot realize automated operation functions. During the removal process, multiple operators are still required to assist in the operation. The removal effect cannot meet actual needs, and the construction cost cannot be saved to the greatest extent. Safety hazards cannot be effectively protected. Utility Model Content

The user can control the sliding walking device 30 to move horizontally forward and backward on the cantilevered boom 21 carrying the electric hoist lifting device 40 only by operating the handle 70. At the same time, the user can also control the electric hoist lifting device 40 to release the scissor-type rail clamp 60 downward through the zipper 41 to clamp the rail 90 for lifting, saving manpower and improving work efficiency.

[0024] In a preferred embodiment, a semi-automatic operation platform for rail removal and transportation in a shield tunnel further includes a cable 80, a pressure column 22 is provided at the top of the support frame 20, one end of a plurality of cables 80 is fixedly connected to the top of the pressure column 22, and the other end is fixedly connected to the cantilever boom 21 at intervals. The cantilever boom 21 is obliquely pulled by the pressure column 22 and the plurality of cables 80, thereby further improving the bearing capacity of the cantilever boom 21.
