Problems solved by technology
[0004] 1. Increase the cost of tunnel construction: the design of widening section or avoidance hole increases the engineering quantity and equipment input cost
[0005] 2. There are potential safety hazards: the widening section or the avoidance hole requires the driver to repeatedly operate or reverse the car for a long distance, and the risk factor is high
[0006] 3. Reduce construction efficiency: It takes a long time for the driver to operate the U-turn, and the use of small engineering vehicles will seriously affect the construction efficiency

Embodiment Construction
[0030] In describing the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", The orientations or positional relationships indicated by "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, rather than indicating or It should not be construed as limiting the invention by implying that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation.
[0031] The technical solution of the present invention is described in detail in conjunction with the accompanying drawings. A mobile tunnel engineering vehicle rotary platform includes a chassis mechanism 1, a rotary platform mechanism 2, a core disk mechanism 3, a transmission mechanism 4, and a running mechanism 5. The core d...

The invention discloses a movable-type tunnel engineering vehicle rotating platform. The movable-type tunnel engineering vehicle rotating platform is characterized in that a chassis mechanism, a rotating platform mechanism, a core disc mechanism, a transmission mechanism and traveling mechanisms are included; the core disc mechanism is arranged on the chassis mechanism, and the rotating platform mechanism is arranged on the core disc mechanism; an upper core disc on the core disc mechanism drives the rotating platform mechanism to rotate through the transmission mechanism so as to rotate a vehicle placed on the rotating platform mechanism; and the traveling mechanisms are arranged on the two sides of the chassis mechanism, and traveling wheels of the traveling mechanisms can ascend and descend through hydraulic cylinders and drive the whole chassis mechanism to move. Semi-automatic mechanized operation is adopted, the problem that the consumed time of u-turn operated by a driver is long is solved, and thus the construction efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a mobile rotary platform for tunnel engineering vehicles. Background technique [0002] At present, with the continuous development of underground engineering, a large number of ultra-long tunnels and small-section tunnels appear. The turning method of engineering vehicles (such as muck trucks, concrete tank trucks, material transport vehicles, etc.) in the tunnel construction in the tunnel is as follows: (1 ) The widening section is designed in the engineering construction drawings, and the vehicle can be turned around only after the driver of the engineering vehicle makes multiple adjustments; U-turn. In addition, in order to meet the clearance requirements of the tunnel, only small engineering vehicles can be used for construction work. [0003] The above solutions have the following disadvantages: [0004] 1. Increased tunnel construction costs: Designing wideni...
