Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in the figure, the automatic oiling device for the linear screen bearing is characterized in that: comprises an automatic oiling pump 1, an oil distributor 2, an oiling ring 3, an oil baffle 4, a photoelectric sensor 5, an alarm 6 and a plc controller 7. The automatic oiling pump 1 uses a plc control gear pump with the model of HTA02-D, realizes automatic oiling amount and oiling frequency adjustment, and simultaneously is connected with a plc controller 7 when the oil amount is automatically alarmed at a low level, and realizes opening and closing oiling through the plc controller 7. The automatic oiling pump 1 is arranged on the upper part of a linear sieve bearing, and because each linear sieve consists of two motor drives and four disc bearings, one motor drives the two disc bearings, the device needs to carry out oiling treatment on the two disc bearings or the plurality of disc bearings, and the oil separator 2 is connected and arranged on the basis of the automatic oiling pump 1, and the oil separator 2 divides the oil from an oil pump into two paths, four paths or multiple paths, so that oiling on a plurality of bearing shafts is realized. The outside of the linear sieve bearing is provided with an oiling ring 3, the oiling ring 3 is provided with an oiling hole and an oil drop hole, and the oil drop hole is arranged at the bottom of the oiling ring 3, so that waste oil is convenient to fall out. The oil filling hole is connected with the oil distributor 2. The bottom of the linear sieve bearing is provided with the oil baffle 4, the oil baffle 4 is arranged at the bottoms of the two linear sieve bearings, the length of the oil baffle 4 is wider than that of the linear sieve bearing, and the installation mode is that the left side is high and the right side is low, so that waste oil can fall into the oil baffle 4 completely and is collected at the lowest point on the right side. The oil shield 4 is provided with a photoelectric sensor 5, the photoelectric sensor 5 is a diffuse reflection photoelectric sensor with the model of CDD-40P, a PNP output pipe is arranged in the sensor, the sensor is normally closed, the PNP output pipe is recovered to be inactive when an object is detected, the black line outputs a low level, namely, when no object is blocked, the sensor is in a closed state, and when the object is blocked, the switch is opened. The photoelectric sensor 5 is arranged at the lowest point in the oil shield 4 and is connected with the alarm 6, and the alarm 6 is a power-off alarm. Since the added oil is black, when a certain amount is accumulated, the photoelectric sensor 5 can be completely blocked, and the photoelectric sensor 5 is switched off, and the alarm 6 gives an alarm. The automatic oiling pump 1 and the photoelectric sensor 5 are connected with the plc controller 7, the plc controller 7 controls the oiling frequency and quantity of the automatic oiling pump 1 and forms a loop with the automatic oiling pump 1 and the photoelectric sensor 5, and when the photoelectric sensor 5 with excessive waste oil accumulation in the oil shield 4 is automatically disconnected, the plc controller 7 closes the automatic oiling pump 1 to stop automatic oiling and wait for the maintenance of staff.

The working process of the utility model comprises the following steps: after the device is installed, a worker initially sets the automatic oiling pump 1 through the plc controller 7, and after the automatic oiling starts after the oil filling amount and the frequency required by the bearing shaft are adjusted, the automatic oiling pump 1 automatically alarms and notifies the worker of adding crude oil when the oil amount is too small in the oiling process. The waste oil after refueling drops into the oil baffle 4 from the oil dropping hole, and is collected to the photoelectric sensor 5 of the lowest point, when the waste oil is too much after long-time refueling, the photoelectric sensor 5 is completely covered by the waste oil, at the moment, the normally closed sensor switch is opened, the alarm 6 receives a power-off signal to send out an alarm, the plc controller 7 closes the automatic oiling pump 1 to stop automatic oiling, and the worker is waited to overhaul. When oil leakage occurs in the device, the photoelectric sensor 5 can be disconnected in time, the plc controller 7 closes the oil pump to refuel and sends out an alarm to remind the emergency repair, so that waste is effectively prevented.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the utility model, and that, although the utility model has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
