Problems solved by technology

[0002] At present, the oil filling process after the general maintenance of railway freight car bearings is manually operated, that is, after the general maintenance bearings are overhauled, they are manually transported to the bearing oiling and fattening machine on the maintenance operation line for oiling; the bearing oiling and fattening machine adopts electronic The weighing instrument does not have the function of intelligent grease injection. Operators need to calculate and subtract according to the value displayed on the electronic weighing instrument and operate accordingly. The problem of insufficient or overweight grease injection often occurs; after the grease is injected, it is manually carried to storage table
The present invention is matched with an electrical control system for a transmission line that automatically conveys general overhaul bearings and automatic quantitative oil injection, and it is the first application in China at present.

Embodiment 1

[0014] Embodiment 1 The components and functions of the electric control system of the oil filling transmission line for railway freight car bearing maintenance:

[0015] The system consists of the main roller horizontal conveyor motor 1, the main roller horizontal conveyor stroke switch 2, the small inclination short roller conveyor stroke switch 3, the electrical control system of the pneumatic bearing oiling and fattening machine 4, the weighing sensor 5, the short Roller horizontal conveyor motor 6, short roller horizontal conveyor stroke switch 7, small inclination short roller conveyor stroke switch 8, storage line stroke switch 9, low-voltage control cabinet 10, PLC programmable controller 11, PLC program 12 , an operation panel or a remote controller 13, and a connecting cable 14. It is characterized in that an electrical control system for an oil filling conveying line for railway freight car bearing maintenance automatically presses and injects bearing grease under ...

Embodiment 2

[0017] Embodiment 2 The working process of the electric control system of the oil filling transmission line for railway freight car bearing inspection and maintenance:

[0018] The overhauled 197726 general overhaul bearing is manually pushed from the overhaul line to the main idler horizontal conveyor, then the system receives the system start signal from the main idler horizontal conveyor stroke switch 2 and starts the main idler horizontal conveyor 1 The motor transports the general maintenance bearing to the small-inclination short roller conveyor. When the bearing slides down by its own weight, it touches the travel switch 3 of the small-inclination short roller conveyor. The bearing is transported to the position of the oil filling weighing platform to stop running. After the weight measurement by the load cell 4, the PLC control program starts the electric grease pump motor 4-1 and the gas booster cylinder solenoid valve 4-2 according to the quantitative oil injection....

Abstract

The invention relates to an electrical control system of a bearing repairing, grease-injecting and conveying line of a railway wagon; the system is mainly composed of a main-roller horizontal conveyor motor 1, a main-roller horizontal conveyor travel switch 2, a small-inclination short-roller conveyor travel switch 3, an electrical control system of pneumatic type bearing grease injecting and homogenizing machine 4, a weighing sensor 5, a short-roller horizontal conveyor motor 6, a short-roller horizontal conveyor travel switch 7, a small-inclination short-roller conveyor travel switch 8, a storage line travel switch 9, a low-voltage control cabinet 10, a PLC (Programmable Logic Controller) 11, a PLC program 12, an operation panel or a remote controller 13 and connecting cables 14. The electrical control system of a bearing repairing, grease-injecting and conveying line of the railway wagon has the advantages that manual carrying operation is replaced and the ordinary bearing repairing process of the railway wagon is automated; the process is controlled precisely, the injected bearing grease is uniform and the amount of the injected grease is stable.

Description

technical field [0001] The invention relates to an electrical control system of an oil injection conveying line for maintenance and maintenance of railway freight car bearings, in particular to a 197726 type general inspection and maintenance oil injection transmission line for bearings of railway freight cars, and belongs to the technical field of automatic control of railway vehicle maintenance equipment. Background technique [0002] At present, the oil filling process after the general maintenance of railway freight car bearings is manually operated, that is, after the general maintenance bearings are overhauled, they are manually transported to the bearing oiling and fattening machine on the maintenance operation line for oiling; the bearing oiling and fattening machine adopts electronic The weighing instrument does not have the function of intelligent grease injection. Operators need to calculate and subtract according to the value displayed on the electronic weighing i...
