An energy-storing self-testing deceleration jack and its testing method

Abstract

This invention proposes an energy-storing self-testing deceleration top and its detection method, belonging to the field of deceleration tops in railway marshalling yard vehicle speed control equipment. It addresses the problems of existing deceleration top status diagnosis, which mainly relies on manual foot-stepping for judgment—a time-consuming, labor-intensive, and highly random method. The invention includes a deceleration top with an external equipment box on one side. The side wall of the external equipment box has an air inlet and an exhaust outlet. A wind turbine generator is housed inside the external equipment box, with its impeller facing the connection between the air inlet and the external equipment box. An energy storage battery electrically connected to the wind turbine generator is also located inside the external equipment box. A signal detection module for detecting the voltage amplitude between the wind turbine generator and the energy storage battery is also installed on the external equipment box. In this invention, no external power supply is required; it is self-powered. The rotation of the fan in the wind turbine generator drives the rotor to cut magnetic field lines, generating electrical energy, which is amplified by the voltage amplification module before detection and energy storage.

Description

Technical Field

[0001] This invention belongs to the field of speed-regulating equipment for railway marshalling yards, specifically relating to an energy-storing self-testing speed-regulating device and its testing method. Background Technology

[0002] Currently, multiple speed reducers are in operation at various railway marshalling yards. The condition diagnosis of speed reducers is mainly done by manually stepping on them to make judgments. Therefore, the daily inspection of speed reducers accounts for about 60% of the maintenance work, which is time-consuming and labor-intensive. Moreover, due to the lack of a clear standard, it is highly random.

[0003] Because each speed reducer is a purely mechanical and relatively independent product, and due to limitations in the available power supply, no advanced sensing equipment can be used, making it an omission in railway informatization. Only the most primitive methods can be used for the maintenance of this speed reducer.

[0004] There is an urgent need to research a convenient, fast, and accurate fault diagnosis device for deceleration tops that can reduce the workload of on-site personnel. Summary of the Invention

[0005] In view of this, the present invention provides an energy-storing self-testing deceleration jack and a testing method to solve the problem that the current deceleration jack condition diagnosis mainly relies on the "mushroom stepping" method, which is judged by manual foot stepping. Therefore, the daily inspection of the deceleration jack accounts for about 60% of the maintenance work, which is time-consuming and labor-intensive, and has a large degree of randomness due to the lack of a clear standard.

[0006] The technical solution adopted in this invention is as follows: A self-testing deceleration top with energy storage includes a deceleration top, an external equipment box on one side of the deceleration top, an air inlet and an air outlet on the side wall of the external equipment box, the end of the air inlet away from the external equipment box communicating with the air outlet of the deceleration top; a wind turbine is installed inside the external equipment box, the impeller of the wind turbine facing the communication between the air inlet and the external equipment box; an energy storage battery electrically connected to the wind turbine is also installed inside the external equipment box; and a signal detection module for detecting the voltage amplitude between the wind turbine and the energy storage battery is also provided on the external equipment box.

[0007] Preferably, the external device box is further provided with a voltage amplification module, which is electrically connected to the wind turbine and the energy storage battery respectively; The signal detection module is used to detect the voltage amplitude after the voltage is amplified by the voltage amplification module.

[0008] Preferably, the signal detection module is electrically connected to the energy storage battery.

[0009] Preferably, the external device box is also equipped with a wireless transmission module, which is electrically connected to the signal detection module, the external terminal monitoring platform and the energy storage battery respectively.

[0010] A method for detecting a deceleration jack, comprising: After the deceleration top is compressed, the airflow generated by it enters the external equipment box through the air inlet and acts on the wind turbine, thereby converting wind energy into electric current. Energy storage batteries store the current generated in wind turbines and power other electrical appliances. The voltage amplification module amplifies the voltage generated by the wind turbine to a certain extent, while the signal detection module detects the amplified voltage amplitude through a voltage sensor and transmits the collected voltage data to the wireless transmission module. The wireless transmission module transmits voltage data from the signal detection module to an external terminal monitoring platform and determines the working status of the deceleration top. First, set the voltage threshold A; If the measured voltage amplitude exceeds A, the air discharged from the deceleration top will generate a large wind speed and be easily pressed down, resulting in a soft top problem. If the measured voltage amplitude is less than A, the air discharged from the deceleration top will generate a small wind speed, making it difficult to be pressed down, resulting in a hard top problem for the deceleration top. If the measured voltage amplitude is within A, it indicates that the deceleration top is working normally.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, no external power supply is required; it is self-powered. The rotation of the fan in the wind turbine drives the rotor to cut magnetic field lines, generating electrical energy. This energy is then amplified by a voltage amplification module for detection and energy storage.

[0012] 2. In this invention, the voltage amplitude of the electrical signal generated by the wind power generation module is detected by the voltage sensor of the signal detection module, and the signal is transmitted to the terminal by the wireless transmission module to determine the working status of the deceleration top, thereby achieving the effect of intelligent detection. This can greatly reduce the time required for manual detection, improve the accuracy of manual detection, and reduce the incidence of accidents.

[0013] 3. In this invention, the self-energy storage state self-testing deceleration top does not require external power supply, can be intelligently detected, has reliable performance, and is suitable for use in the field of railway vehicle speed control equipment. Attached Figure Description
