[0026] Reference Figure 1 The embodiment provides a locomotive low-voltage equipment test bench, which comprises a test cabinet 3, a maintenance cabinet 2 and a disassembly and assembly cabinet 1. The test cabinet 3, the maintenance cabinet 2 and the disassembly and assembly cabinet 1 are sequentially spliced to form a test bench in a concave shape. An operator can stand in the concave part of the test bench, test the low-voltage equipment by using the low-voltage equipment test device 9 in the test cabinet 3, judge whether the performance and function of the low-voltage equipment meet the requirements, disassemble the low-voltage equipment by using tools on the disassembly and assembly cabinet 1 if there is a fault, then maintain and replace the damaged or faulty parts in the maintenance cabinet 2, assemble and install the low-voltage equipment on the disassembly and assembly cabinet 1, and finally retest on the test cabinet 3. The test of the low-voltage equipment can be completed after ensuring that the low-voltage equipment is used normally.

[0027] At this time, the operator does not need to frequently carry the low-voltage equipment to the maintenance area or the disassembly and assembly area in the workshop to perform corresponding work, thereby reducing the carrying difficulty, shortening the carrying time, reducing the work intensity, increasing the work efficiency, and meeting the actual work requirements.

[0028] Further explanation, in order to further improve the work efficiency, a plurality of locomotive low-voltage equipment test benches are arranged in the factory area, and each locomotive low-voltage equipment test bench is used for completing the test of a fixed type of low-voltage equipment. Therefore, the operator only needs to prepare corresponding disassembly and assembly tools and the low-voltage equipment test device 9, so as to reduce the preparation time of the disassembly and assembly tools and the preparation time of the low-voltage equipment test device 9.

[0029] Preferably, a tool hanging plate 6 is installed on the maintenance cabinet 2. The tool hanging plate 6 is vertically arranged on the top end face of the maintenance cabinet 2, and the tool hanging plate 6 is detachably connected with the maintenance cabinet 2, so as to facilitate transportation after disassembly and assembly.

[0030] The tool hanging plate 6 is used for placing tools for disassembling and assembling corresponding low-voltage equipment and maintenance tools.

[0036] In actual use, the operator can connect the low-voltage equipment testing device 9 and the corresponding low-voltage equipment through wiring to improve the wiring efficiency.

[0037] In order to facilitate viewing of test data and test results, the display screen 7 is movably connected to the test cabinet 3 through an adjusting support 8, so that the height and angle of the display screen 7 can be adjusted during actual operation, which facilitates viewing and reduces the space occupied by the display screen 7 on the test cabinet 3, facilitating the placement of low-voltage equipment and the operation of personnel.

[0038] Since various tools, equipment and parts need to be frequently placed on the locomotive low-voltage equipment test bench, in order to increase the service life of the locomotive low-voltage equipment test bench, wear-resistant pads are arranged on the locomotive low-voltage equipment test bench, that is, corrosion-resistant and wear-resistant PVC pads are arranged on the upper end surfaces of the test cabinet 3, the maintenance cabinet 2 and the disassembly and assembly cabinet 1, which is low in cost and convenient to replace.

[0039] In actual use, the height of the test cabinet 3, the height of the maintenance cabinet 2 and the height of the disassembly and assembly cabinet 1 are all equal and can be selected to be 700mm-800mm, preferably 750mm; the height of the tool hanging plate 6 can be selected to be 400mm-500mm, preferably 450mm; the length of the tool hanging plate 6 can be selected to be the same as the length of the maintenance cabinet 2, preferably 1200mm; the width of the maintenance cabinet 2 can be selected to be 800mm, and the length of the test cabinet 3 and the length of the disassembly and assembly cabinet 1 are all equal and can be selected to be 1800mm, and the width of the test cabinet 3 and the width of the disassembly and assembly cabinet 1 are all equal and can be selected to be 600mm.
