Embodiment

[0025] The following is attached figure 1 , attached figure 2 , attached image 3 , taking K16A ore hopper car bottom door and opening and closing mechanism assembly as an example, the present invention will be described in further detail.

[0026] The bottom door of the ore hopper car and the opening and closing mechanism are composed of three bearings 1, two double-center bearings 2, a long shaft 3, a short shaft 4, a short shaft 2 5, an opening and closing air cylinder 6, and four opening and closing levers 7. Composition of two bottom doors 8, four bottom door end plates 9, middle beam upper plane 10, process backing plate 11, car body composition 12, hinge seat 13, gear 14, rack 15, bell crank 16, etc. .

[0027] The specific assembly method is as follows:

[0028] A. The bearing assembly 1 is assembled on the upper plane 10 of the middle sill, and the process backing plate 11 is assembled and welded on the installation position of the double-center bearing 2, and th...

Abstract

The invention relates to the field of machines, in particular to an assembling method for a wagon broadsword type bottom door opening and closing mechanism. Through the processes of overall machining on the installation face a bearing pedestal of a transmission shaft to ensure the planeness, on-site matched welding of bottom door end boards and a bottom door assembly, and the like, the assembling problem of the bottom door opening and closing mechanism caused by accumulative errors and welding deformation in the wagon manufacturing process is effectively avoided, the production efficiency is effectively improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an assembly method of a large knife-type bottom door opening and closing mechanism for railway wagons. Background technique [0002] When assembling the large-sword bottom door opening and closing mechanism of railway freight cars, firstly, the bearing seat is directly installed on the upper plane of the middle beam, and the level of the transmission shaft is adjusted by adding an adjustment pad under the bearing seat; then the bottom door is assembled with the car body, and finally The opening and closing lever connects the bottom door and the drive shaft for debugging of the bottom door. [0003] There are many shortcomings in the assembly method of the opening and closing mechanism of the large knife-type bottom door of the existing railway freight car, mainly in the following aspects: 1. The upper plane of the center beam is uneven, and it is time-consuming and laborious to adjust th...
