TECHNICAL FIELD
[0001] The utility model relates to a railway signal machine bulb lighting simulation test device. BACKGROUND
[0002] The railway signal machine plays a vital role in the railway transportation system, which mainly undertakes the instruction function of indicating train operation and shunting operation, like the "traffic indicator" of railway transportation, and the accuracy of its signal is directly related to the safety and efficiency of train operation. Under normal circumstances, the ordinary signal bulb used by the railway signal machine has a relatively simple working principle, and once the filament is connected, the current can emit light, and if the filament is broken, the bulb cannot be lit. However, during the transportation of the signal bulb, due to the influence of various factors such as vibration and collision, there is a risk of filament breakage or imminent breakage. A seemingly intact bulb that is damaged during transportation may go out at any time after being installed on the signal machine, which will bring great safety hazards to railway operation and even endanger train safety.
[0003] At present, there is an urgent need for a test bench that can test bulb lighting. Before the signal bulb is put into use, it must be sent to a professional testing agency for testing. By simulating the actual working state through the test bench, the bulb can be tested for a long time, and bulbs with potential problems can be found in advance. UTILITY MODEL CONTENTS
[0004] In view of the deficiencies of the prior art, the utility model provides a railway signal machine bulb lighting simulation test device, which can independently test the quality of the bulb, without the need to send the bulb to an external detection, thereby reducing the transportation cost, detection cost and other costs generated by the detection, and the device is convenient to assemble and disassemble and efficient to detect.
[0005] To achieve the above-mentioned purpose, the utility model provides a railway signal machine bulb lighting simulation test device, which comprises a base, an alternating current power supply and a plurality of test modules are arranged on the base, the test modules are arranged in parallel with the alternating current power supply, the test module comprises a transformer and a lamp holder for installing a bulb to be tested, the main filament on the lamp holder is connected with the Z terminal of the transformer, the auxiliary filament on the lamp holder is connected with the F terminal of the transformer, the return terminal column on the lamp holder is connected with the H terminal of the transformer, the lamp holder is provided with an assembly opening, two limiting grooves are formed in the side wall of the assembly opening, a connecting shaft and two pokers are arranged in the lamp holder, one end of the two pokers is rotatably connected to the connecting shaft, the other end of the two pokers respectively extends to the corresponding limiting groove and extends to the outside of the limiting groove and is provided with a limiting piece, a touch button is arranged between the two pokers, the touch button is arranged in a tapered shape with a small lower part and a large upper part, a reset spring for resetting the touch button is sleeved on the touch button, and a traction spring for making the two pokers close and keeping the limiting piece outside the limiting groove is further connected between the two pokers.
[0006] The beneficial effect of such an arrangement is that, by such an arrangement, testing can be carried out in batches, and different problems of the transformer can be detected, such as simultaneous lighting of the main and auxiliary filaments after replacement of a new bulb, or a broken filament or a bulb gas leakage, etc., so that the on-site fault can be simulated and analyzed, and preventive measures can be formulated in a timely manner to reduce the occurrence of faults and improve the reliability of the equipment.
[0007] As a further arrangement of the present application, the lower end surface of the limiting piece is connected with a soft pad, and a rubber pad is connected to the contact surface of the limiting groove with the soft pad.
[0008] The beneficial effect of such an arrangement is that, during the bulb testing process, the limiting piece is subjected to a resisting force, generating a horizontal component force, and if the friction between the limiting piece and the limiting groove is insufficient, these component forces can cause the limiting piece to retract into the limiting groove, causing the bulb to lose effective positioning and affecting the accuracy and stability of the test.
[0009] As a further arrangement of the present application, the end portion of the limiting piece is bent and arranged into the assembly opening.
[0010] The beneficial effect of the arrangement is that when the tester inserts the bulb into the assembly opening, the bent end of the limiting sheet can effectively guide the bulb to enter the correct position naturally, avoiding the situation that the bulb is difficult to be positioned due to the deviation of the insertion angle, and effectively improving the installation efficiency.
[0011] As a further arrangement of the utility model, the limiting sheet is arranged in an arc shape at the abutting end of the bulb to be tested.
[0012] The beneficial effect of the arrangement is that the arc-shaped abutting end greatly increases the contact area with the bulb, compared with the ordinary flat abutment, and can more comprehensively and closely adhere to the surface of the bulb. When the limiting sheet limits the bulb, the larger contact area ensures the stability of the abutment, and can ensure that the bulb is always accurately limited under any slight vibration or external interference, avoiding the situation that the bulb is loose or displaced due to the inaccurate abutment, thereby comprehensively ensuring the accuracy and stability of the bulb testing of the railway signal machine.

[0017] The utility model provides a kind of railway signal machine bulb light simulation test device embodiment, such as Figs. 1 to 4As shown, including the base, the base is provided with AC power supply and several test modules, the test module is provided in parallel with AC power supply, the test module includes transformer and the lamp holder 1 for installing the bulb to be tested, the main filament on the lamp holder 1 is connected with the transformer Z terminal, the auxiliary filament on the lamp holder 1 is connected with the transformer F terminal, the return terminal column on the lamp holder 1 is connected with the transformer H terminal, the lamp holder 1 is provided with the assembly opening 11, two limiting grooves are formed in the side wall of the assembly opening 11, the connecting shaft and two pokers 3 are arranged in the lamp holder 1, one end of the two pokers 3 is rotatably connected with the connecting shaft, the other end of the two pokers 3 respectively extends to the corresponding limiting groove and extends outwardly from the limiting groove and is provided with the limiting piece 4, the toggle 2 is arranged between the two pokers 3 on the lamp holder 1, the toggle 2 is arranged in the shape of a tapered cone with small lower part and large upper part, the reset spring for resetting the toggle 2 is sleeved on the toggle 2, and the traction spring for making the two pokers 3 close and keeping the limiting piece 4 outside the limiting groove is further connected between the two pokers 3. The beneficial effects of such arrangement are: such arrangement, through such structure, can test in batches, and can detect different problems according to the transformer, for example, the main and auxiliary filaments are lit at the same time after the new bulb is replaced; or one of the filaments is broken, the bulb leaks gas and other phenomena, which can effectively simulate and analyze the on-site fault, timely formulate the fault prevention measures, reduce the fault occurrence and improve the equipment reliability. When installing the bulb to be tested, the bulb is pressed against the assembly opening 11 of the lamp holder 1, the bulb will touch the limiting piece 4, the limiting piece 4 has a certain elasticity and can be deformed, after the bulb is installed in place, the limiting piece 4 is reset and tightly touches the edge of the bulb, realizing accurate positioning of the bulb, avoiding deviation and looseness during bulb installation and other problems, ensuring that the bulb can work stably during testing, greatly improving the accuracy of test data. After the test is completed, the bulb is also easy to disassemble. Only the toggle 2 is pressed, the tapered cone structure of the toggle 2 with small lower part and large upper part under the pressing action makes the two pokers 3 open.

The coarse soft pad and the rubber pad cooperate with each other to greatly increase the friction. When the horizontal component force acts, the limiting sheet 4 can be stably kept outside the limiting groove, and continuously provides reliable limiting support for the bulb, so as to ensure that the bulb is always in the correct position during the entire test process.
