Description

Technical Field

[0001] The present invention relates to the technical field of subway vehicle maintenance, in particular to a subway vehicle debugging test pressurizing device. Background Art

[0002] In the field of subway train brake resistor box maintenance, the performance of the resistor box, as a core component, directly affects the train braking safety. Traditional detection methods have problems such as scattered equipment, cumbersome operation and insufficient accuracy, which have been unable to meet the needs of efficient operation and maintenance of modern rail transit. The traditional maintenance process has the following prominent problems: Traditional testing procedures rely on separate tools such as alligator clips and multimeters, which are performed step by step. Connecting the alligator clips to the brake resistor busbar requires frequent plugging and unplugging for a single test. For example, testing the temperature control board resistance requires manual point-by-point measurement with a multimeter. Furthermore, operators must carry and operate separate instruments for testing the temperature control board, brake resistor, and fan wind direction and pressure, increasing the time required to prepare the testing instruments and the pressurization steps and testing time during vehicle commissioning. Since the traditional debugging test pressurization device is a fixed structure, manual work is required under the vehicle when the vehicle is powered on for debugging. There is a high risk of electric shock from contact with high-voltage components, and there is a lack of real-time warning mechanism for misoperation. It may also cause safety hazards such as failure of heat dissipation of the brake resistor box, and at the same time, the safety protection of maintenance personnel is insufficient. Summary of the Invention

The conductive bolt 706 can be electrically connected to the conductive block 704. When it is necessary to test the temperature control board of the resistor box, the second plug 901 is pulled out to release the electrical connection of the resistor 9, and then the conductive bolt 706 is rotated downward to electrically connect to the conductive core 703.

After the second plug 901 is installed, the electrical connection between the circuit board 701 and the resistor 9 is completed.

[0023] Example 2, based on Example 1, Figures 1-14 As shown, it is necessary to set up a resistance testing module, a wind direction testing module, and a temperature control detection module on the basis of the host computer 2 and the circuit board 701. The resistance testing module integrates a high-precision resistance tester, supports the synchronous detection of the temperature control board resistance and the total resistance and phase resistance difference of the brake resistor. The phase sequence relay of the wind direction testing module monitors the output phase sequence in real time. The wind pressure sensor communicates with the host computer 2 through the interface and dynamically displays the wind pressure curve.

[0024] The working principle of this embodiment is as follows: First, install the host computer 2 on the outside of the vehicle body 1 with bolts, fix the two electric motors 301 to the bottom of the vehicle body 1, connect the drive shaft to the threaded rod 302, and use the horizontal positioning structure of the rotating hole to ensure the vertical stability of the threaded rod 302; Insert the first lifting frame 401 and the second lifting frame 501 into the first positioning rod 101 through the sliding hole, and insert the threaded rod 302 through the threaded hole. Install the hinge rod 6 above the first lifting frame 401 and the second lifting frame 501. Connect the drainage frame 402 and the socket 502 to the hinge rod 6 through the bottom sliding hole to form an adjustable angle hinge structure. Insert the first plug 201 into the socket 502. It is necessary to integrate the resistance test module, wind direction test module, and temperature control detection module in the host computer 2, and connect them with the circuit board 701, wind pressure sensor and other components through cables; Temperature control board detection step: pull out the second plug 901 of the resistor 9 to disconnect the electrical connection between the resistor 9 and the circuit board 701; turn the conductive bolt 706 downward to make it contact with the conductive core 703 of the circuit board 701, and at the same time ensure that the conductive block 704 contacts the temperature control board pin through the ejector pin. The ejector pin must be installed in advance between the conductive block 704 and the locking bolt 705; operate the host computer 2 and select the temperature control board detection function. The system automatically measures the resistance value of the temperature control board through the resistance test module, compares it with the standard value, and outputs a qualified or unqualified result; Braking resistor resistance detection step: reinsert the second plug 901 into the circuit board 701 to restore the electrical connection between the resistor 9 and the circuit board 701; keep the ejector pin in contact with the three output copper bars of the braking resistor to ensure that the conductive bolt 706 is conductive to the conductive block 704; select the resistance detection function on the host computer 2, and the system will synchronously measure the total resistance and the phase resistance difference; In the wind direction and wind pressure detection step, the electric motor 301 is controlled to drive the threaded rod 302 to rotate, so that the first lifting frame 401 drives the drainage frame 402 to rise until the sealing ring is in close contact with the air outlet of the resistance box. The power supply of the resistance box fan is turned on, and the air flow drives the impeller 403 to rotate. The wind pressure sensor collects the wind pressure value in real time, and the wind pressure curve is displayed on the host computer 2 through the wind direction test module. The system verifies the fan phase sequence through the phase sequence relay. The green indicator light indicates that it is correct. Combined with the wind pressure value, it automatically determines whether the fan direction and performance are qualified. Manually push the drainage rack 402 or the socket 502 to disengage the locking protrusion of the hinged rod 6 from the locking groove. After adjusting to the desired angle, release it. The support spring pushes the locking protrusion to re-engage the locking groove to complete the angle locking. The extrusion frame 8 above the socket 502, under the action of the support spring, squeezes the first plug 201 and the circuit board 701 through the friction block to ensure a stable electrical connection and avoid poor contact between the first plug 201 and the circuit board 701. During the test, the resistance box must be powered off to avoid safety accidents caused by live operation. When adjusting the drainage rack 402, push slowly and observe the fit of the sealing ring to prevent damage to the equipment due to excessive force. A pressure sensor can be set on the basis of the drainage rack 402. Through the above steps, the temperature control board, resistor plate and fan system of the subway train brake resistor box can be efficiently tested, thereby improving the inspection accuracy and safety.
