Compartment of bottom dumping tramcar

Abstract

The invention discloses a compartment of a bottom dumping tramcar. The compartment comprises a high-end wall assembly, a low-end wall assembly and two side wall assemblies. The high-end wall assemblycomprises first end plates, a first upper end beam, a middle cross beam and end cross beams. The tops of the first end plates are bent outwards to form V-shaped structures, and the first upper end beam is arranged in openings of the V-shaped structures for sealing. The side wall assemblies each comprise a side plate, an upper side beam, a supporting beam and a lower side beam, wherein the upper side beam is transversely arranged at the top of the outer side of the side plate and corresponds to the first upper end beam. The low-end wall assembly comprises a second end plate and a second upper end beam, the second upper end beam is arranged on the outer side of the second end plate and corresponds to the supporting beam. In this way, the compartment of the bottom dumping tramcar is firm in structure, compartment main body supporting beam pieces are connected end to end to form a closed supporting beam frame, and the overall carrying capacity of the compartment is improved.

Description

technical field [0001] The invention relates to the technical field of mining vehicles, in particular to a compartment of a bottom-side unloading type mining vehicle. Background technique [0002] Bottom side unloading mine car (hereinafter referred to as mine car) is a special vehicle suitable for mine rail transportation. This type of mine car can complete the unloading action by opening the bottom side by means of gravity and unloading curved track. [0003] The bottom side unloading mine car is mainly composed of a carriage, a movable chassis and a coupler buffer device. The underframe and one side of the compartment are hinged, and the underframe can rotate around the shaft along the longitudinal direction of the vehicle. The underframe and the other side of the compartment are overlapped, and unloading rollers are set in the movable underframe. Support beams are symmetrically arranged on both sides of the carriage along the track to support the carriage when the vehic...
