Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The invention uses the combination of the high-precision electric pushing rod controlled by the servo motor and the force sensor to realize the real-time synchronous test of the electromagnetic pushing force of the elevator drum brake along with the displacement change of the plunger head. The electromagnetic thrust is tested and recorded by the force sensor, and the displacement of the plunger head is tested and recorded by the high-precision electric push rod. The real-time monitoring of the relation between the electromagnetic thrust and the displacement of the plunger head can be realized through the action of the brake driven by the control unit each time, and a relation curve is drawn in the same coordinate plane through the display unit; the elevator drum brake as a test object is horizontally arranged and is consistent with a normal working state; the number of actions of the elevator drum brake is recorded by using a laser displacement sensor as a counter.
The elevator drum brake electromagnetic force real-time testing device comprises the following components:
1. the elevator drum brake 3 is a test object, and the brake plunger 8 is a member that performs a specific mechanical operation after the elevator drum brake 3 is energized. The L-shaped baffle 2 is positioned at one side of the elevator drum brake 3 which is horizontally arranged and plays a role in limiting the left and right movement of the elevator drum brake 3. The elevator drum brake 3 and the L-shaped baffle 2 are connected to the mounting platform 1 through threads;
2. the laser reflection plate 4 is mounted on the stopper plunger head 8. The laser reflecting plate 4 can move along with the brake plunger head 8 and is used for cooperating with the laser displacement sensor 5 to measure the mechanical movement of the brake plunger head 8 and record the movement times. The laser displacement sensor 5 is connected to the mounting platform 1 through a laser displacement sensor mounting frame 6;
3. the electric pushing bar 10 is driven by a servo motor 11 and is connected to the mounting platform 1 through a supporting platform 7 with adjustable height. The output end of the electric push rod 10 is connected with a force sensor 9. The electric pushing rod 10, the force sensor 9 and the center of the brake plunger head 8 are positioned on a uniform horizontal line by adjusting the height of the supporting platform 7. The force sensor 9 is brought into close contact with the stopper plunger head 8 by driving the extending action of the push lever 10. Meanwhile, the adjustment of the air gap of the brake can be realized by driving the push rod 10 to stretch;
4. the control unit 13 is used for driving and controlling the actions of the elevator drum brake 3, the servo motor 11 and the electric push rod 10;
5. the display unit 12 is used for acquiring, recording and displaying the input voltage and current signals, the signals of the laser displacement sensor 5, the signals of the force sensor 9 and the position signals of the electric push rod 10 in real time. In particular, the signal of the force sensor 9 and the position signal of the electric push bar 10 can be displayed simultaneously on the same coordinate axis; converting the mechanical action times of the stopper plunger head 8 by capturing the signal change of the laser displacement sensor 5 and displaying;
6. all components were mounted in place before testing was initiated. The belt power sensor 9 presses back the brake plunger head 8 to the initial position by driving the extending action of the push lever 10;
7. at the start of the test, the elevator drum brake 3 and the servomotor 11 are energized by the control unit 13. The elevator drum brake 3 generates electromagnetic force after being energized and tries to push the brake plunger head 8 to produce an outwardly extending action. The brake plunger head 8 presses the pressure sensor 9, and enables the pressure sensor 9 to generate an electric signal capable of reflecting the magnitude of the electromagnetic force, and the electric signal is collected and recorded by the display unit 12. At the same time, a position signal of the electric push lever 10 is collected and recorded as a displacement signal of the outward projecting action of the stopper plunger head 8.
8. The electric push rod 10 is slowly retracted by the driving of the servo motor 11. Under the action of electromagnetic force, the brake plunger head 8 is always pressed against the force sensor 9. In this process, the display unit 12 collects and records the signal of the pressure sensor 9 and the position signal of the electric push bar 10 in real time, and displays the displacement value of the brake plunger head 8 from the electromagnetic force value of the pressure sensor 9 and the position signal of the electric push bar 10;
9. after the stopper-plunger head 8 reaches the limit position, the stopper-plunger head 8 is disengaged from the force sensor 9, the value of the electromagnetic force displayed by the display unit 12 becomes zero, and the test is ended.
10. The laser displacement sensor 5 may be used to assist in the measurement of the displacement of the brake plunger head 8 during the test.
11. The test can be performed again by driving the extending action of the push rod 10, and the brake plunger head 8 is pressed back to the original position by the driving force sensor 9. The number of tests can be identified and recorded by the signal change of the laser displacement sensor 5.
