Description

Technical Field

[0001] This invention belongs to the field of railway signal relay technology, and particularly relates to a railway signal relay tilting simulation device. Background Technology

[0002] Currently, there is a problem that when a certain railway signal relay is tilted, its time parameters and electrical characteristics change, or it even fails. The reason is that the railway signal relay uses gravity as a reaction force. When tilted, the direction of gravity changes, which causes the relay's reaction force characteristics to change.

[0003] Currently, there is a problem where the electrical characteristics of a certain railway signal relay change significantly when it is de-energized and tilted to the left, right, or forward by about 45° relative to its normal operating position. When tilted to the left, right, or forward by more than 90°, the railway signal relay fails. The reason is that the railway signal relay has no initial holding force, which makes it highly sensitive to the influence of gravity. When the direction of the force exerted by gravity on the railway signal relay changes, the railway signal relay has difficulty switching or even cannot complete the switching.

[0004] Currently, there is no suitable relay placement angle measuring device on the production line. Using a handheld relay for testing cannot effectively and quantitatively control the tilt angle, and hand tremors or changes in angle may occur during the testing process. Summary of the Invention

[0005] This invention addresses the issue of changes in time parameters and electrical characteristics of relays when tilted. It proposes a simulation device for tilting railway signal relays, enabling the testing of electrical characteristics and time parameters of a certain railway signal relay at quantitative tilt angles in different directions. Using this device, it is possible to determine the minimum tilt angle within which the time parameters and electrical characteristics of the relay change. Furthermore, this device can be used to verify subsequent relay optimization schemes.

[0006] To achieve quantitative testing of the tilt angle of railway signal relays in different directions, this invention proposes a railway signal relay tilt placement simulation device. Using this invention, after setting the horizontal and vertical rotation angles in the program, the stepper motor automatically rotates to the target angle, and time parameters and electrical characteristics are tested at the required angle.

[0007] To quantitatively test the relay's timing parameters and electrical characteristics at the required tilt angle, and to control its position from changing during the test, a railway signal relay tilting simulation device was invented. Through the control system and stepper motor, the relay can be quantitatively rotated to the required angle.

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include: A railway signal relay tilting simulation device includes a motor drive assembly, a tilt angle rotation assembly, and a relay fixing assembly, wherein: The motor drive assembly includes a first stepper motor, a second stepper motor, and a base. The tilt angle rotation assembly includes a horizontal rotation arm and a vertical rotation arm; The relay fixing assembly includes a rotating platform plate and a relay plug plate; A transverse rotating arm is rotatably mounted on the base, and a longitudinal rotating arm is rotatably mounted inside the transverse rotating arm. A rotating platform plate is fixed inside the longitudinal rotating arm, and a relay plug plate is fixed on the rotating platform plate. A first stepper motor is fixed on the base, and the transverse rotating arm is driven by the first stepper motor. A second stepper motor is fixed on the transverse rotating arm, and the longitudinal rotating arm is driven by the second stepper motor.

[0009] Furthermore, the motor drive assembly includes a first stepper motor, a first coupling, a first stepper motor bracket, a second stepper motor, a second coupling, a second stepper motor bracket, and a base.

[0010] Furthermore, the stepper motor bracket is mounted on the base with screws; The stepper motor is mounted on the stepper motor bracket by screws; The coupling is mounted on a rotating shaft of the stepper motor.

[0011] Furthermore, the second stepper motor bracket is mounted on the transverse rotating arm by screws; The second stepper motor is mounted on the second stepper motor bracket by screws; The two couplings are mounted on the rotating shafts of the two stepper motors.

[0012] Furthermore, the tilt angle rotation assembly includes a torque transmission rod one, a torque transmission rod two, a plane bearing, a transverse rotating arm, and a longitudinal rotating arm.

[0013] Furthermore, the torque transmission rod one passes through the rotation center through hole of the transverse rotating arm and the base and is connected to the coupling one. The torque transmission rod one is fixedly connected to the rotation center through hole of the transverse rotating arm. The torque transmission rod one is rotatably connected to the base through a plane bearing. The torque transmission rod one is fixedly connected to the rotating shaft of the stepper motor one through the coupling one.

[0014] Furthermore, the torque transmission rod two passes through a rotation center through hole of the longitudinal rotating arm and a side through hole of the transverse rotating arm and is connected to the coupling two. The torque transmission rod two is fixedly connected to a rotation center through hole of the longitudinal rotating arm. The torque transmission rod two is rotatably connected to a side through hole of the transverse rotating arm through a plane bearing. The torque transmission rod two is fixedly connected to the rotating shaft of the stepper motor two through the coupling two. After passing through the other rotation center through hole of the longitudinal rotating arm and the other side through hole of the transverse rotating arm, the hexagonal bolt is fastened by a nut. The hexagonal bolt is rotatably connected to the other rotation center through hole of the longitudinal rotating arm through a plane bearing, and the hexagonal bolt is rotatably connected to the other side through hole of the transverse rotating arm through a plane bearing.

[0015] Furthermore, the relay fixing assembly includes a rotating platform plate, double-ended studs, flange nuts, a plug adapter plate, and a relay plug plate.

[0016] Furthermore, one side of the double-ended stud is screwed to the rotating platform plate, and the other side passes through the through hole used to fix the longitudinal rotating arm platform and is then tightened with a flange nut; The plug-in adapter plate is screwed onto the rotating platform plate; The relay plug is tightened to the plug adapter plate with hex bolts.

[0017] The beneficial effects of this invention are: 1. This invention uses a stepper motor to precisely control the rotation angle of the relay in the horizontal and vertical directions, enabling the testing of time parameters and electrical characteristics at a fixed tilt angle. Compared with the method of using a handheld relay, this invention provides more precise control over the placement of the relay, and can provide more accurate experimental data for subsequent relay optimization. 2. This invention achieves stable relay testing under a fixed tilt state through a mechanical structure. Compared with testing by hand, it can ensure that the relay does not jitter or change tilt angle during the test, thus ensuring the repeatability accuracy of the relay under the same tilt state and reducing the test error of the relay under different tilt angles. 3. This invention enables testing of relays at different tilt states by rotating the horizontal and vertical arms. Compared with handheld relay testing, this invention can achieve testing at any tilt state of 360°, and can verify the tilt angle margin of the relay over a wider range. Attached Figure Description
