Description

Technical Field

[0001] This utility model relates to the field of substation maintenance technology, specifically a mobile substation maintenance tool vehicle. Background Technology

[0002] As the core hub of the power system, substations undertake the critical functions of power conversion, distribution, and transmission. Their operational stability directly affects the safety of electricity use for social production and daily life. To ensure the long-term reliable operation of substations, regular equipment inspections, maintenance, and emergency repairs are necessary. During maintenance, personnel must carry a large number of specialized tools (such as transformer testers, cable strippers, insulating rods, multimeters, etc.) and small parts (such as bolts, washers, and voltage detectors), and must move flexibly between different work sites (such as outdoor equipment areas, high-voltage switchyards, and relay protection rooms).

[0003] A search revealed that patent authorization announcement number CN 211220574 U discloses a mobile substation maintenance tool vehicle, "including a chassis, a lifting support, and a maintenance platform. The chassis is topped with, from bottom to top, a lifting support, an induction platform, a tool compartment, a maintenance platform, and a guardrail. A ladder is installed on the side of the chassis. A side panel is fixed inside the tool compartment, and a first track groove and a second track groove are respectively provided on the tool compartment and the side panel. A support rod is provided on the side of the side panel, and a drawer and a first slider are connected to the support rod. The first slider is connected to the first track groove. A support base is provided at the bottom of the drawer." The base is fixed on the support rod, and a second slider is installed at the bottom of the support base. The second slider is connected to the second track groove. The chassis is supported only by the wheels touching the ground. Its stability depends entirely on the contact state between the wheels and the ground. In the outdoor operation scenario of substation, the ground conditions are complex (such as potholes, gravel, slopes or uneven cement ground). The wheels are prone to deflection or shaking due to ground undulations or external disturbances (such as personnel getting on and off the vehicle, or tools being carried), which can lead to vehicle instability or even overturning. Such accidents threaten the personal safety of maintenance personnel (such as falling or being injured by falling tools). Utility Model Content

This design allows the retrieval port 20 to better fit the fan-shaped partition groove, making it convenient to retrieve and place tools.

[0031] The working principle of this utility model is as follows:

[0032] When in use, first move the tool cart to the target work point, then unfold the four support arms 4 and start the electric outriggers 5. The electric outriggers 5 extend downward to support the tool cart. The electric control system (such as the controller setting the locking pressure value) ensures that the outriggers are rigidly connected to the ground, forming a combination support between the wheels and the electric outriggers 5, completely eliminating the shaking of the vehicle body.

[0033] Open the equipment box 12 or tool drawer 13 at the bottom of the toolbox 11 to take out large equipment or medium tools, or rotate the transparent cover 19 to take out the corresponding small tools. Then, the maintenance personnel climb onto the platform plate 8 via the climbing ladder 10, and then start the hydraulic lifting frame 7 to raise the platform plate 8 to the designated height for maintenance. After the maintenance is completed, put the used tools back into the toolbox 11 according to their categories. Then, the electric outriggers 5 retract and the support arms 4 are stored and fixed to both sides of the vehicle plate 1 by magnetic attraction. Then, the tool cart can be pushed or pulled by the traction ring 26.
