Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete transportation, in particular to a rail-mounted concrete transport truck. Background Art
[0002] Due to its safety, speed, efficiency, environmental protection and other characteristics, TBM tunnel boring machines are used more and more in tunnel construction. In the construction of tunnels by the TBM method, since the excavation section of the TBM is circular, the available space for construction operations at the bottom of the tunnel is less. By laying inverted arch precast blocks or steel sleepers at the bottom of the tunnel, a platform with a certain width is constructed for laying out the transportation system to transport construction materials. In tunnels with a small cross-section, rail transportation is generally used for material transportation. Since various operation gantries such as lining trolleys are also arranged in the tunnel, the rail transportation formation needs to pass through the reserved passage holes inside the gantries. Therefore, rail transportation locomotives and various vehicles all adopt a small-size and compact design form.
[0003] The rail-mounted concrete transport truck generally adopts a longitudinal horizontal layout form. The tank body is a long cylinder type, and a discharge port is arranged at one end. The discharge port is provided with a closable lid. During the concrete loading and transportation process, the lid is in a closed state to prevent the concrete from flowing out. A partition is arranged inside the tank body. During the concrete transportation period, the tank body is always in a rotating state, so that the concrete is continuously stirred, which can prevent the concrete from segregation and performance degradation. When the concrete is discharged, the lid at the end of the tank body is opened, and the concrete is discharged by rotating the tank body in the reverse direction. Since the tank body is always in a horizontal placement state, during the rotation of the tank body, most of the concrete in the tank body is in a local range stirring state. Especially the concrete at the front and rear ends of the tank body, due to uneven stirring, the problem of concrete segregation often occurs, resulting in uneven performance of the concrete in the tank body, affecting the concrete pouring and the quality of the building entity.
