Displaying device for opening degree of bottom door of railway hopper wagon

Abstract

The invention discloses a displaying device for the opening degree of a bottom door of a railway hopper wagon and belongs to the technical field of the railway hopper wagon. In an I-type scheme, the displaying device is a straight table displaying device, a stay wire fixing lug is fixedly installed on a transmission shaft rear end lug of the railway hopper wagon in the prior art, one end of a stay wire fixed to a compartment bottom board is connected with the stay wire fixing lug, and the other end of the stay wire is connected with the straight table displaying device. In an II-type scheme, the displaying device is a dial plate type displaying device, a stay wire fixing lug is fixedly installed on a transmission shaft rear end lug of the railway hopper wagon in the prior art, one end of a stay wire fixed to a compartment bottom board is connected with the stay wire fixing lug, and the other end of the stay wire is connected with the straight table displaying device. The two schemes have the advantages that a visual reference is given to an operator, the situation that the bottom door of the railway hopper wagon is not completely closed is avoided, and the operator is guided to safely operate; and if the displaying device is installed on each of two side portions of the wagon, an inspection member can conveniently detect whether the bottom door of the railway hopper wagon is completely closed or not after the wagon is started.

Description

technical field [0001] The invention belongs to the technical field of railway hopper wagons, and in particular relates to a display device for the opening degree of the bottom door of the railway hopper wagon. Background technique [0002] At present, the switch of the bottom door of the railway hopper wagon at home and abroad is as follows: figure 1 , 2 As shown, when the railway hopper wagon transports bulk materials, the unloading is completed by opening the bottom door 10 on the bottom plate 1 of the carriage. When unloading, the bottom door 10 of the hopper car needs to be opened, and the operator operates the brake cylinder 3 to push the front ear 5 of the front end of the rotating shaft fixed on the front end of the rotating shaft 4 to rotate, and the ear 6 at the rear end of the rotating shaft fixed to the rear end of the rotating shaft 4 Rotate, drive the pull bar 7 that is hinged with it to move, the car door shaft front end lug 8 that is fixed on the left end o...

AI Technical Summary

Problems solved by technology

The disadvantage of this structure is that the opening and closing of the bottom door is through the interlocking action of the mechanism. After the unloading operation is completed, the operator cannot see the opening of the bottom door 10, and cannot fully confirm whether the bottom door is completely closed or is stuck by objects such as stones. , unable to close the door normally, once the hopper car is not completely closed, the hopper truck will cause the loaded materials to be thrown during the driving process, resulting in property loss, excessive leakage and even major accidents such as train derailment
