Description
Technical Field
The invention belongs to the technical field of trackless rubber-tyred vehicle lubrication, and particularly relates to a rapid automatic grease filling lubricating device.
Background
At present, the auxiliary transportation system of the trackless rubber-tyred vehicle is basically adopted in the ten-million-ton mine in China, the trackless rubber-tyred vehicle transportation equipment has the advantages of flexibility in maneuvering, large carrying capacity and small turning radius, point-to-point non-disassembly continuous transportation of equipment, particularly large materials, can be realized, links such as material marshalling, transferring, loading and unloading during traditional rail transportation are omitted, and the mine production preparation efficiency is greatly improved.
The reliability of the trackless rubber-tyred vehicle directly influences the mine transportation efficiency, and the trackless rubber-tyred vehicle runs in severe environments with high coal dust concentration, high humidity, poor ventilation conditions and the like for a long time, so that the maintenance is very important. The usage amount of more than 300 rubber-tyred vehicles in a mine every day greatly increases the lubricating work of the vehicles. The lubricating points of the heavy equipment bicycle are more than 50, and the lubricating points of the heavy equipment bicycle can be more than 50. During actual maintenance, not only do grease injection lubrication at each motion part waste time and energy, but also workers easily leak some key lubrication points during maintenance, and major faults of equipment can be caused, and the operation and maintenance cost is increased.
After the automatic grease injection pump is adopted, grease is conveyed to each lubricating point through a pipeline, so that the lubricating points can be lubricated while time is saved. As shown in fig. 1, the conventional automatic grease injection lubricating device includes a centrifugal cam 1, a pressure ring 2, a piston 3, a cylinder 4 and a check valve 5, wherein one end of the piston 3 is in close contact with the edge of the centrifugal cam 1 through the pressure ring 2, the other end of the piston 3 is disposed in the cylinder 4, the other end of the cylinder 4 is provided with the check valve 5, the eccentric distance of the centrifugal cam 1 is 10mm, and the maximum stroke of the piston in linear motion is 20mm when the centrifugal cam rotates. However, the conventional automatic grease injection lubricating device adopts a centrifugal cam structure, and the inherent characteristics of the device determine that the piston can only do a complete reciprocating motion when the centrifugal cam rotates for a circle, so that oil can be sucked and discharged once, the oil output of the grease pump is less, the lubricating time is longer, and the working efficiency is low. In addition, the butter stirrer adopts a simple deflector rod structure, so that when butter is fed into the cylinder under pressure, the lubricating oil supply at the cylinder is limited due to the small areas of the deflector rod and the pressing sheet and the limited extrusion capacity, the problem that the butter cannot be sucked by the cylinder is possibly caused, the oil suction is not smooth, and the oiling quality is influenced.
In addition, the existing automatic lubrication system works regularly, and the lubrication point does not need oil and works once every certain time. The system is lack of a protection mechanism, and when oil is not needed, on one hand, grease is seriously wasted, and the maintenance cost is increased; on the other hand, the continuous oil pumping may cause the pipeline pressure to rise, and safety accidents are caused.
Disclosure of Invention
