A rotating and sliding integrated dual-function movable top cover

Abstract

The invention discloses a rotating and sliding integrated dual-function movable roof, which comprises a lower roof, an upper roof, a transmission device for the lower roof, and a drive device for the upper roof. The transmission device for the lower roof is fixed on the top of the end wall. The lower roof transmission device is connected with the lower roof cover, and the lower roof cover is moved by the lower roof transmission device, so that the charging port of the funnel car roof is opened or closed. A plurality of charging ports, the upper top cover is slidably arranged on the lower top cover, the upper top cover driving device is connected with the upper top cover, and the upper top cover is moved by the upper top cover driving device, so that the lower top cover The charging port is opened or closed. The present invention adopts the way that the top cover of the upper layer and the lower layer are matched, and the top cover of the upper layer and the lower layer have different purposes respectively, so that the same railway wagon can realize the loading and transporting function of large particles and dust particles at the same time, has good versatility, and improves the utilization of the vehicle rate, in line with market diversification requirements.

Description

technical field [0001] The invention belongs to the technical field of railway wagons, in particular to a rotating and sliding integrated dual-function movable top cover. Background technique [0002] With the rapid development of railway wagons today, with the improvement of people's awareness of safety and environmental protection, the moisture-proof, moisture-proof, and wind-proof of goods during railway transportation has become the top priority. Therefore, in order to effectively isolate goods Adding a windproof and rainproof top cover is a necessary measure. At present, according to the different opening and closing forms, the movable roof of the railway hopper car is generally divided into a translation movable roof, a hinged movable roof and a rotating movable roof. Due to the difference in the type and volume of the goods to be shipped, the vehicle needs to be designed with different sizes of loading ports and use different opening and closing methods. Vehicles lo...

[0003] However, under normal circumstances, the same vehicle has only one charging port or multiple charging ports of the same size. Due to the limitation of the size of the charging port and the structure of the top cover, the vehicle can only be used for special use, and the utilization rate is low, which increases the The cost
