Description

Technical Field

[0001] The utility model relates to the field of instrument detection and maintenance, in particular to a driver controller test bench. Background Art

[0002] The driver controller is a manual electrical device used by the driver to control the locomotive, which controls the locomotive forward and backward, and the diesel engine speed adjustment to control the locomotive acceleration and deceleration. It is an important electrical component of the locomotive. At present, a total of 11 locomotives of the company's Dongfeng locomotives and industrial and mining locomotives use TKS9 driver controllers. The control circuit of TKS9 driver controller is as follows Figure 1 As shown, it is divided into a reversing handle and a main control handle, and has multiple operating gear circuits.

[0003] In the actual production process, the TKS9 driver controller operates frequently, more than 1,000 times a day. After the internal quick-acting switch is used too many times, the switch will fail, which will cause the locomotive to be unable to run normally. After the TKS9 driver controller fails, in order to find out which gear the fault occurs in, the test maintenance personnel often need to turn the handle to traverse all gears with one hand and use a multimeter to measure with the other hand. Not only is the operation cumbersome and difficult for one person to complete, but the driver controller has many switches and complex logical relationships, and it is easy to miss the fault point during measurement, resulting in the driver controller still having a fault point after maintenance. In addition, the fault situation is not intuitive when using a multimeter to detect, and the fault is difficult to be directly and quickly determined. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a driver controller test bench, which aims to solve the problem that the existing troubleshooting only uses a multimeter for detection, which is not only difficult for one person to complete, but also time-consuming and labor-intensive, and the fault gear cannot be quickly determined, and the single-combat detection is not intuitive.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a driver controller test bench, including a storage table for placing the driver controller, the storage table is a horizontal platform, a display panel is connected to the storage table, the display panel is connected to a power supply, the display panel is provided with L1, L2, L3, L4, L5, L6 and L7 indicator lights, and a control circuit for the indicator lights is provided inside the display panel, specifically, a contact a1 is provided, a1 is connected to control L1 through wiring, a contact b1 is provided, b1 is connected to control L2 through wiring, a contact c1 is provided, c1 is connected to control L3 through wiring, a contact d1 is provided, d1 is connected to control L4 through wiring, and a contact e1 is provided, e1 is connected to control Control L5, set contact f1, and control L6 through wiring on f1, set contact g1, and control L7 through wiring on g1; two aviation plugs for connecting to the driver controller are connected on the display panel, and the internal circuit of the aviation plug is connected to the indicator light control circuit. Through the aviation plug, the driver controller's reversing handle forward gear circuit can be connected to contact a1, the reversing handle reverse gear circuit can be connected to contact b1, the main handle 0 gear circuit can be connected to contact g1, the main handle 1 gear circuit can be connected to contact c1, the main handle downshift circuit can be connected to contacts c1 and d1 at the same time, the main handle gear holding circuit can be connected to contacts c1, d1, and f1 at the same time, and the main handle upshift circuit can be connected to contacts c1, d1, e1, and f1 at the same time.

[0006] A further improvement of the technical solution of the utility model is that the display panel is vertically arranged on the storage table.

[0007] A further improvement of the technical solution of the utility model is that two aviation plugs are placed on the storage table, a storage groove for fixing the driver controller is provided between the two aviation plugs on the storage table, and an anti-slip pad is provided in the storage groove.

[0008] A further improvement of the technical solution of the utility model is that L1 and L2 on the display panel have the same specifications and are arranged vertically on the right side of the display panel, and L3, L4, L5, L6, and L7 have the same specifications and are smaller than L1 and L2 and are arranged horizontally on the left side of the display panel.

[0009] A further improvement of the technical solution of the utility model is that: the two aviation plugs are provided with a fool-proof structure to prevent reverse insertion when connecting to the driver controller.

[0010] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is: by setting two aviation plugs and a display panel with a built-in circuit, the driver controller can be connected to the display panel and connected to the circuit of the control indicator light inside the display panel. A tester can operate the gear and observe the on and off of the indicator light on the display panel. The indicator light wiring is used. After the contacts of each gear are actuated, the corresponding indicator light is powered on and the gear is normal. Otherwise, it means that the driver controller is faulty, and then the faulty gear is judged, which saves time and effort, and does not require the complicated use of a multimeter to measure a large number of connection points. In addition, the gear fault type is indicated by the on and off of the indicator light, and the fault type can be intuitively displayed, and it is very easy to judge. By distinguishing the size and arrangement of the indicator light, the fault judgment distinction between the reversing handle and the main control handle is more direct and the judgment is more intuitive. By setting a fool-proof structure on the aviation plug, the left and right aviation plugs on both sides will not be plugged in reverse when connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described in detail below in conjunction with the embodiments:

[0016] like Figure 1 As shown in the figure, it is the circuit diagram of the TKS9 driver controller. From the control circuit diagram, it can be seen that the TKS9 driver controller can be divided into a reversing handle and a main handle. The reversing handle has forward gear and reverse gear, and the main handle has 0 gear, 1 gear, downshift, hold gear and upshift. Each gear position corresponds to the connection of the corresponding circuit. Figure 1 The internal structure and circuit logic relationship of the driver controller are shown in the figure to make a driver controller test bench. The structure of the driver controller test bench is as follows Figure 2As shown, the main body is a storage table, which is a horizontal platform for placing the driver controller on the storage table for subsequent inspection operations. The storage table can also be used to place other detection and maintenance instruments. A display panel is connected to the storage table. In this embodiment, the display panel is placed vertically on the storage table and perpendicular to the storage table. This makes it convenient to observe the display panel when operating the driver controller. The display panel is connected to the power supply to obtain power. The display panel is provided with L1, L2, L3, L4, L5, L6 and L7 indicator lights to display the power supply status of different gears of the driver controller, so as to determine whether each gear is faulty. The control circuit of the indicator light is provided inside the display panel as shown in the figure. Figure 3 As shown by Figure 3 It can be seen that the control circuit of the indicator light is for Figure 1The control circuit of the driver controller is completely corresponding.

Contact g1 is set, and L7 is controlled by wiring connection on g1. Two aviation plugs for connecting to the driver controller are connected on the display panel, and the internal circuit of the aviation plug is connected to the indicator light control circuit. The various gear circuits of the driver controller can be connected to each contact through the aviation plug. Specifically, the contact between the aviation plug and each gear circuit of the driver controller leads to the internal control circuit of the display panel to connect to the respective contacts. Specifically, the aviation plug can connect the front gear circuit of the driver controller reversing handle to contact a1, the rear gear circuit of the reversing handle to contact b1, the main handle 0 gear circuit to contact g1, the main handle 1 gear circuit to contact c1, the main handle downshift circuit to contacts c1 and d1 at the same time, the main handle gear retention circuit to contacts c1, d1, and f1 at the same time, and the main handle upshift circuit to contacts c1, d1, e1, and f1 at the same time. In order to better distinguish the gear position failure of the main handle and the reversing handle, the size and arrangement position of the indicator lights are distinguished. Specifically, L1 and L2 on the display panel have the same specifications and are arranged vertically on the right side of the display panel, and L3, L4, L5, L6, and L7 have the same specifications and are smaller in size than L1 and L2, and are arranged horizontally on the left side of the display panel. Two aviation plugs are connected to the display panel through wires, and the aviation plug body is placed on the storage table. There is a storage slot for fixing the driver controller between the two aviation plugs on the storage table, and a non-slip pad is placed in the storage slot. It is convenient to place the driver controller stably on the storage table during actual testing, which is convenient for testing. The two aviation plugs are equipped with a foolproof structure to prevent reverse insertion when connecting the driver controller. The two aviation plugs can ensure that one is accurately inserted into the driver controller on the left and the other on the right, and will not be connected reversely. The built-in circuit of the driver controller is connected to the internal circuit of the display panel.

[0017] Working principle or usage: Place the driver controller on the storage table of the driver controller test bench, connect the aviation plugs on both sides, turn on the power, operate the driver controller handle, and observe whether the indicator lights up according to the circuit logic at the corresponding position.
