In addition, the contact induction device can also comprise a protective cover 6, the protective cover 6 can be sleeved on the peripheries of the induction magnetic block 1 and the supporting frame 2, and the lower part of the protective cover 6 can be connected with a lubricating oil distributor through threads. In order to make the connection tighter and prevent the device from coming loose, a sealing element 7 may be provided between the protective cover 6 and the lubricant distributor, which acts as a seal.
It should be noted that the induction magnetic block 1 is in threaded connection with the supporting frame 2, and the relative position of the induction magnetic block and the supporting frame 2 can be further adjusted by adjusting the threaded connection, so as to meet the addition requirements under different conditions, and greatly improve the applicability of the contact induction device.
Fig. 2 is a front sectional view of another embodiment of the lubricant distributor according to the present invention.
As shown in fig. 2, and referring to fig. 1 in combination, in this embodiment, in addition to the contact sensing device for detecting the state of the lubricant distributor, the lubricant distributor according to the present invention may further include an oil outlet 9 and an oil inlet 10 respectively communicated with the lubricant storage chamber 8. An oil outlet 9 may be provided at a lower portion of the lubricating oil storage chamber 8, and the piston 5 may be effective to discharge the lubricating oil stored in the lubricating oil storage chamber 8 from the oil outlet 9 when the indicator rod 4 linearly moves downward following the piston 5. The oil inlet 10 is arranged on the side wall of the lubricating oil storage cavity 8, and lubricating oil can be timely supplemented and added into the lubricating oil storage cavity 9.
In addition, in the embodiment, the piston 5 drives the indicating rod 4 to linearly move, so that the lubricating oil stored in the lubricating oil storage chamber 9 is ejected out of the oil outlet 9. The upper end of the indicating rod 4 leaves the induction magnetic block 1. When the upper end of the indicating rod 4 leaves the magnetic induction block 1, the magnetic induction block 1 can output a second signal to a control device (not shown in fig. 2) through the data transmission line 3.
It should be noted that the control device may include a PLC, and when the control device detects a jump from the first signal to the second signal, the control device may determine that the lubricant dispenser pumps out the lubricant stored in the lubricant storage chamber 8.
FIG. 3 schematically illustrates system component connections of an embodiment of the lubrication distribution control system of the present invention.
As shown in fig. 3, in this embodiment, the lubricating oil distribution control system according to the present invention may further include a first oil inlet 101 and a second oil inlet 102 in the lubricating oil distributor, in addition to the lubricating oil distributor described above. The first oil inlet 101 and the second oil inlet 102 are connected to the lubricating oil reservoir 13 through a first oil feed line 111 and a second oil feed line 112, respectively. Furthermore, a pump 14 can be provided on the first oil feed line 111 and/or the second oil feed line 112, which pump can be connected to a control device (not shown in fig. 3) in the lubricating oil distribution control system according to the invention.

When the pump arranged on the first oil supply pipeline 111 starts to operate, the control device can control the movable switch 12 in the lubricating oil distributor to block the second oil supply pipeline 112, the pump on the first oil supply pipeline 111 pumps lubricating oil into the first oil supply pipeline 111, the lubricating oil can enter the lubricating oil storage cavity 8 through the first oil inlet 101, because the first oil inlet 101 is arranged at the upper end of the position, opposite to the lubricating oil storage cavity 8, of the piston 5, under the action of the pressure of the lubricating oil, the piston 5 can be pushed vertically downwards, further, the piston 5 can drive the indicating rod 4 to linearly downwards move, the lubricating oil stored at the lower end of the piston 5 in the lubricating oil storage cavity 8 is pushed by the piston 5 and can be discharged through the oil outlet 9, and the oil-filling process of the lubricating oil distribution control system is achieved. The movable switch 12 blocking the second oil supply pipeline 112 can effectively prevent the lubricating oil from flowing back into the lubricating oil storage container 13 from the second oil supply pipeline 112 connected with the second oil inlet 102.
Similarly, after the oil pumping process is finished, the oil outlet 9 and the pump on the first oil supply pipeline are closed, the control device can control the pump arranged on the second oil supply pipeline 112 to start working, lubricating oil is pumped into the second oil supply pipeline 112 by the pump on the second oil supply pipeline 112, the lubricating oil can enter the lubricating oil storage cavity 8 through the second oil inlet 102, because the second oil inlet 102 is arranged at the lower end of the position, opposite to the lubricating oil storage cavity 8, of the piston 5, the piston 5 can be pushed vertically upwards under the action of the lubricating oil pressure, and then the piston 5 can drive the indicating rod 4 to linearly move upwards, and the lubricating oil stored at the upper end of the piston 5 in the lubricating oil storage cavity 8 can flow back into the lubricating oil storage container 13 through the first oil inlet 101 under the pushing action of the piston 5. When the indicating rod 4 contacts the induction magnet block 1, the movable switch 12 blocks the first oil supply pipeline 111, and the pump arranged on the second oil supply pipeline stops working, so that the oil filling process of the lubricating oil distribution control system is completed.
In addition, the combination of the features in the present application is not limited to the combination described in the claims of the present application or the combination described in the embodiments, and all the features described in the present application may be freely combined or combined in any manner unless contradictory to each other.
It should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. It is apparent that the present invention is not limited to the above embodiments and similar changes or modifications can be easily made by those skilled in the art from the disclosure of the present invention and shall fall within the scope of the present invention.
