Description
Technical Field
The invention relates to a hopper car, in particular to a hopper car bottom door opening mechanism.
Background
The K18G type hopper wagon is a special wind-controlled self-discharging wagon. The vehicle can realize the whole-line unloading, the grouped unloading and the single unloading. The vehicle can be manually unloaded under the condition of no wind source.
At present, most uncovered hopper cars in China adopt a large-blade opening and closing mechanism (such as K16, K18, K70 and the like). The mechanism has simple structure, few parts, convenient manufacture and assembly, reasonable arrangement of the 'cutter bar' and generally reliable locking action as long as a certain self-locking eccentricity can be ensured.
The opening and closing of the bottom door can be realized as long as necessary rotating torque is provided for the transmission shaft. The bottom door pull rod is similar to a large knife, so the bottom door pull rod is called a 'large knife' type opening and closing mechanism.
The large knife type opening and closing mechanism realizes self-locking by forming a self-locking eccentric distance by the fact that a large knife (namely a bottom door connecting rod) passes through a dead point.
When the door is opened, the knife must pull the bottom door a small distance into the vehicle when the knife passes through the dead point to release the self-locking. This movement of the bottom door by the cargo contained in the vehicle is very resistant. Therefore, a sufficient external force must be applied to overcome the resistance to release the self-locking mechanism and open the bottom door. The self-locking can be released only by rotating the transmission shaft by an angle of about 6 degrees.
However, the transmission shaft must be rotated by an angle of about 93 ° to fully open the bottom door. When the door is opened manually, the torque is required to be more than or equal to 45 kN.m. According to investigation, the users use the most or manually open the door during the use process, and the large torque brings great inconvenience to the users. In order to reduce the manual door opening moment. Aiming at the characteristic, a transmission mechanism at the lower part of the door opening mechanism is improved, and a relay door opening mode is adopted, so that the door opening moment is greatly reduced.
