Abstract

The invention provides an automatic lubricating system, which includes a liquid-driven grease pump, a hydraulic-controlled reversing valve, a distributor, a grease tank, an oil cylinder and a wedge group; the oil inlet of the system is connected to the working oil port of the reversing valve of the main engine; The oil circuit A and oil circuit B of the system are connected with the oil cylinder; the oil cylinder is connected with the wedge group to drive the movement of the wedge group; the oil circuit A and the oil circuit B are equipped with a liquid-driven grease pump; the liquid-driven grease pump is controlled by a hydraulic The reversing valve is respectively connected with the distributor and the grease tank, and the distributor outputs the grease to the wedge group to realize the lubrication of the wedge group. The invention adopts the form of liquid-driven and liquid-controlled grease injection, which not only has the function of synchronous automatic quantitative lubrication, but also has the function of self-protection due to lack of grease, that is, when the oil and grease are insufficient, the speed is automatically reduced to protect the wedge group and remind the user to add grease; Continuously adjust the amount of grease output to meet the lubrication needs of different working conditions while saving grease consumption to the greatest extent; the closed pressure grease tank is adopted, which can significantly improve the self-priming capacity of the grease pump.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to an automatic lubrication system. Background technique [0002] The splitter is one of the key rock-breaking components of tunnel construction equipment such as excavators, drilling and splitting trolleys, and extremely hard rock boring machines, as well as rescue equipment and ore mining equipment. It has high power density, safety and reliability, flexible use, and No vibration, no impact, no noise, no dust, etc., can be widely used in tunnel excavation, house reconstruction, municipal construction, ore mining, emergency rescue and other fields, especially in the surrounding environment that can not be blasted, no impact, no vibration It is the best rock-breaking equipment for construction conditions such as extremely hard rock tunnels, short tunnels, and special-shaped cross-section tunnels. [0003] During the construction of the splitter, one of the mos...
