Fig. 1 shows an automatic lubricating device for lubricating an assembly line of a towed chain engine, which comprises an oil storage tank 1, a two-position two-way electromagnetic directional valve 2, a throttle valve 3, an oil nozzle 4 and a time relay 5, wherein the oil storage tank, the two-position two-way electromagnetic directional valve 2, the throttle valve 3 and the oil nozzle 4 are sequentially connected from top to bottom through oil pipes, the time relay 5 is connected with two leads, and an output terminal of the time relay 5 is connected with an input terminal of the two-position two-way electromagnetic directional valve 2 and is used for controlling the opening and closing of the valve of the two-position two-way electromagnetic.
The working principle of the automatic lubricating device is as follows:
the device is arranged on a side wall below a trench, and the oil nozzle 4 is just opposite to a ground drag chain 9 below the oil nozzle, so that the normal operation of the ground drag chain is not influenced. Lubricating oil in the oil storage tank 1 flows out through an oil pipe by means of self weight, passes through the two-position two-way electromagnetic directional valve 2 and then the throttle valve 3, and then drips and leaks from the oil nozzle 4 onto the ground drag chain 9, so that the purpose of automatic lubrication is achieved. The oil storage tank 1, the two-position two-way electromagnetic directional valve 2, the throttle valve 3 and the oil nozzle 4 form a lubricating oil channel together. When the device is used, parameters are set in the time relay 5, and the two-position two-way electromagnetic directional valve 2 is used for automatically controlling when to switch on or switch off the lubricating oil channel; the throttle valve 3 can be adjusted to control the oil quantity passing through the lubricating oil channel in unit time during oil filling, so that the ground drag chain 9 can be automatically filled with oil at regular time and quantity for lubrication.
In conclusion, the lubricating device provided by the invention can automatically lubricate the ground drag chain at regular time and quantity, replaces the existing manual operation, solves the problems of easy waste and low working efficiency in the oiling process, and simultaneously ensures the safety and reliability of the oiling work.
The lubricating device provided by the invention is low in manufacturing cost, and simple and trouble-saving in daily maintenance.
