Abstract
The utility model relates to an alarm device of on-line monitoring tractor bearing trouble belongs to mechanical equipment's check out test set field. The adjustable support is arranged, a magnetic probe is fixed on a tested bearing at the front end of the adjustable support, the magnetic probe is connected with a signal input end of a PLC (programmable logic controller) in a detection electric box through a signal transmission wire, a reset switch, an alarm indicator lamp and an audible and visual alarm are installed on the detection electric box, the alarm indicator lamp and the audible and visual alarm are connected with a signal output end of the PLC, and the reset switch is connected with the signal input end of the PLC. The beneficial effects of the utility model are that, can carry out effective detection at the initial stage that the tractor bearing has the damage, detection effect is sensitive reliable, and audible-visual alarm effect is obvious simultaneously, and on-line monitoring is respond well.
Description
Technical Field
The utility model relates to a mechanical equipment's check out test set field, a alarm device of on-line monitoring tractor bearing trouble is said in detail.
Background
As is known, in a mechanical transmission structure, a large number of bearings are used as a support for a rotating part, and particularly, the bearing at a heavy-load part of a tractor has a high failure rate and is frequently damaged, and the failure of the bearing cannot be judged in advance by naked eyes. At present, the conventional method is used for recognizing the rotation sound or the bearing breakage card and then performing disassembly and maintenance. The method has the following defects: failure judgment is not timely, and a large number of bearing damage and other damages are only repaired and replaced, so that the production and maintenance cost of equipment is influenced.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides an alarm device of on-line monitoring tractor bearing trouble discovers hidden danger such as bearing damage in advance, greatly reduced equipment failure rate and cost of maintenance.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an alarm device of on-line monitoring tractor bearing trouble, be equipped with adjustable support, characterized by, the measured bearing position of adjustable support front end is fixed with magnetic probe, magnetic probe links to each other with the signal input part that detects the PLC programmable controller in the electronic box through the signal transmission wire, install reset switch, alarm indicator lamp and audible-visual annunciator on the detection electronic box, alarm indicator lamp and audible-visual annunciator link to each other with PLC programmable controller's signal output part, reset switch is connected with PLC programmable controller's signal input part.
The beneficial effects of the utility model are that, can carry out effective detection at the initial stage that the tractor bearing has the damage, detection effect is sensitive reliable, and audible-visual alarm effect is obvious simultaneously, and on-line monitoring is respond well.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure 1, a bearing position to be measured; 2. a magnetic probe; 3. an adjustable support; 4. a signal transmission wire; 5. a reset switch; 6. an alarm indicator light; 7. detecting an electric box; 8. an audible and visual alarm.
Detailed Description
In fig. 1, the utility model discloses be equipped with adjustable bracket 3, the measured bearing position 1 of 3 front ends of adjustable bracket is fixed with magnetic probe 2, magnetic probe 2 links to each other through signal transmission wire 4 and the signal input part who detects the PLC programmable controller in electronic box 7, install reset switch 5 on the detection electronic box 7, alarm indicator 6 and audible-visual annunciator 8 link to each other with PLC programmable controller's signal output part, reset switch 5 is connected with PLC programmable controller's signal input part.
And the magnetic probe 2 is close to the tested bearing position 1 by utilizing the adjustable bracket 3, and the preset distance is debugged and debugged. When a failure sign such as breakage occurs in the bearing unit 1 under test, radial run-out occurs. Thereby triggering the magnetic probe 2 and transmitting the probe signal to the detection electronic box 7 through the signal transmission lead 4. The detection electronic box outputs an alarm signal to the alarm indicator lamp 6 and the audible and visual alarm 8 to remind the maintenance personnel to check and remove faults in time, and the reset is completed through the reset switch 5 after the completion so that the whole system is monitored again.
