Spiral unloading type tramcar for conveying bulk materials

Abstract

The invention discloses a spiral unloading type tramcar for conveying bulk materials. The spiral unloading type tramcar for conveying the bulk materials comprises a carriage, a rotating shaft, tramcar wheels and traction assemblies. The tramcar comprises the carriage, the rotating shaft, a pair of tramcar wheels and two sets of traction assemblies and four traction chains. The traction assemblies are symmetrically connected with the two ends of the rotating shaft. The tramcar wheels are symmetrically installed on the rotating shaft between the carriage and the traction assemblies. The traction chains are symmetrically connected with the traction assemblies of the two sides of the carriage. The carriage can rotate by 360 degrees around the rotating shaft, unloading of the materials can be completed in the rotating process, and the center of gravity of the carriage is always below the center line of the rotating shaft under an overhanging state. Damping rings are arranged between spokes and wheel hubs of the tramcar wheels. The damping rings are made from an elastomer material. By using the connection of the traction chains and the traction assemblies, a plurality of spiral unloading type tramcars can be connected and pulled to form a tramcar unit. According to the spiral unloading type tramcar for conveying the bulk materials, the traction chains mainly play a traction role and a bearing role, rails mainly play a guide role, and the tramcar is more steady and flexible during running.

Description

technical field [0001] The invention relates to a rotary unloading mine car used for bulk material transportation. Background technique [0002] At present, the well-known mine car that is used for bulk material transportation mainly contains: five kinds of tipping mine car, fixed mine car, foot-operated mine car, side unloading mine car, and bottom unloading mine car. These five types of mine cars are all fixedly installed mine wheel sets on the bottom frame of the mine car. The main load of the mine car is borne by the wheel set. transport work. The bearing and guiding are realized by the wheel set. The uneven loading of materials and the bumping of the mine car will make the center of gravity of the mine car unstable, prone to shaking, falling, rollover, derailment and other accidents, and the damage to the wheel set is obvious. Wheelsets have a shorter service life. At the same time, none of these five types of mining vehicles can achieve 360-degree rotation of the mi...

Problems solved by technology

The bearing and guiding are realized by the wheel set. The uneven loading of materials and the bumping of the mine car will make the center of gravity of the mine car unstable, prone to shaking, falling, rollover, derailment and other accidents, and the damage to the wheel set is obvious. Shorter wheel life

At the same time, none of these five types of mining vehicles can achieve 360-degree rotation of the mining vehicle, and the maximum rotation angle does not exceed 90 degrees. It is difficult to completely unload the material in a short time, especially when the material is wet and sticky, the phenomenon of unclean unloading is very common.
