Description

Technical Field

[0001] The embodiments of this utility model belong to the field of EMU maintenance technology, and more specifically, relate to a charging fixture for EMU maintenance tools. Background Technology

[0002] Current EMU maintenance operations exhibit three main characteristics: First, the work area is extensive, requiring a single maintenance operation to cover the entire 16-car trainset, totaling over 400 meters in length. Second, the work period is concentrated, typically requiring the entire maintenance process to be completed within a 4-hour maintenance window due to timetable constraints. Third, tool usage is intensive, with a single Level 1 maintenance operation requiring over 30 tools, including electric wrenches, electric guns, and electric drills. The existing charging management model has significant technical flaws: due to fire safety regulations, charging facilities must be located in a separate charging room 500 meters away from the work area, resulting in a 15-20 minute time commitment per battery replacement. Statistics show that effective work time lost due to charging interruptions during a single maintenance operation reaches 23%, further causing batteries to remain in a shallow charge-discharge state for extended periods (average cycle depth only 47%), leading to accelerated capacity degradation of lithium battery packs (annual degradation rate exceeding 18%) and a failure rate as high as 0.3 times per tool per month. Meanwhile, the frequent back-and-forth movement of workers between the enclosed vehicle and the charging room (averaging 12 kilometers of walking distance per day) poses safety hazards such as slipping and collisions. In the past three years, minor injuries caused by such issues have accounted for 17% of all accidents.

[0003] The traditional charging management models commonly used in the industry include: 1. Centralized charging architecture: setting up an independent charging room outside the maintenance depot, equipped with universal charging cabinets; 2. Manual battery scheduling: assigning dedicated tool administrators to be responsible for battery replacement registration and transportation, and using manual barcode scanning to record charge and discharge cycles; 3. Passive early warning mechanism: simple low battery alarm based on voltage detection, with the trigger threshold set at 20% of battery capacity; 4. Fire isolation design: the charging room adopts Class A fireproof walls, is equipped with a heptafluoropropane automatic fire extinguishing system, and maintains a 500-meter safe distance from the work area.

[0004] This charging management model is too cumbersome to implement on-site. Although it improves electrical safety, it greatly reduces maintenance efficiency. Therefore, a charging fixture for EMU maintenance tools is needed to improve overall maintenance efficiency while ensuring electrical safety. Utility Model Content

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1As shown in the figure, this utility model embodiment provides a charging fixture for EMU maintenance tools, including a cabinet 1. The cabinet 1 is divided into multiple functional compartments by partitions, including a charging compartment 2, a tool compartment 3, a storage compartment 4, a power supply compartment 5, and a wire compartment 6. The charging compartment 2 holds chargers for various power tools for charging their batteries. The tool compartment 3 stores power tools for maintenance and for storing tools not currently in use. The storage compartment 4 stores chargers and batteries of different specifications for different power tools, for replacing the chargers or batteries in the charging compartment 2. The power supply compartment 5 contains a power source 51 for supplying power to the chargers in the charging compartment 2. The wire compartment 6 contains wires connected to the input end of the power source for charging the power source. The cabinet 1 is also equipped with casters 7 for moving the cabinet 1 around the maintenance site, providing timely battery replacement and charging for the power tools. By installing a power supply in cabinet 1 and extending it to the maintenance site, replacement batteries are provided for electrical tools. Replaced batteries are then promptly charged using the power supply, avoiding the clutter caused by running power lines to the maintenance site, which would affect maintenance work and safety. This provides a power guarantee for electrical tools, allowing them to be swapped and charged on-site, thus facilitating maintenance work.

[0038] like Figure 2 , 3 As shown, the charging compartment 2 has one or more layers arranged horizontally. An internal base plate has a circular turntable 21. The top surface of the turntable is evenly divided into multiple rotating compartments 22 by strip partitions. The rotation of the turntable 21 moves different rotating compartments 22 to the opening of the charging compartment 2, facilitating battery charging and power extraction. The charger is located in one of these rotating compartments 22 and is used to charge the battery. A frustum is located at the center of the turntable 21. Each rotating compartment 22 on this frustum has a five-hole socket, which is connected to a power source 51 via a wire. The charger draws power from these five-hole sockets to charge the battery. The charging compartment 2 has a first limiting plate 24 on its side wall, and the corresponding height of the turntable 21 has a second limiting plate 25 on its edge. Under the action of the first limiting plate 24 and the second limiting plate 25, the turntable 21 can only rotate one revolution clockwise or counterclockwise, so as to prevent the turntable 21 from rotating in the same direction when taking power or charging, which would cause the internal wires to get tangled, affect the output of the circuit, or even damage the wires.

[0039] As a further preferred embodiment, the rotating compartment 22 is provided with a temporary fixing structure for securing the charger. The charger is detachably connected to the rotating compartment 22 via this temporary fixing structure, facilitating the replacement of chargers for different power tools and charging them. Simultaneously, by temporarily securing the charger, it prevents shaking during the movement of the cabinet 1, which could cause the charger in the charging compartment 2 to shift, resulting in clutter inside the charging compartment 2 and affecting charging efficiency.

[0040] As a further preferred embodiment, the opening of the charging compartment 2 is also provided with a door panel. When not charging, the door panel can be closed to prevent the charger inside from being exposed to the external environment for a long time and causing damage.

[0041] like Figure 4 As shown, the tool compartment 3 is located on the side of the charging compartment 2 and is vertically arranged. It includes a pull-out hanging plate 31 and telescopic hanging rods 32 mounted on the pull-out hanging plate 31. The pull-out hanging plate 31 is located in the tool compartment 3 and is slidably connected to it via a slide rail, allowing it to slide along the tool compartment 3. The inner end of the pull-out hanging plate 31 has an inner baffle to prevent power tools from falling into the tool compartment 3 and affecting the sliding of the pull-out hanging plate 31; the outer end has an outer baffle to create a closed space when it retracts into the tool compartment 3, preventing damage to the power tools exposed to the air; the bottom has a base plate to connect the outer baffle and the inner baffle, thereby enhancing the overall structure of the pull-out hanging plate 31. The inner side of the pull-out hanging plate 31 also has multiple telescopic hanging rods 32. The rear end of each telescopic hanging rod 32 is a telescopic rod, and its front end bends upward to form a barb, on which the power tools are hung. The length of the telescopic pole is adjusted according to the shape and size of the power tool to avoid the surrounding telescopic hanging poles 32 obstructing the suspended power tool.

[0042] like Figure 5 As shown, the storage compartment 4 includes a drawer 41, which is divided into multiple storage compartments 42 by partitions. Spare batteries, chargers, and unused chargers are stored in these compartments 42. Labels can also be affixed to the partitions separating the compartments 42 for categorizing batteries and chargers. By dividing the storage space in the drawer 41 into multiple smaller storage compartments 42, batteries and chargers for different power tools can be categorized and stored, facilitating quick retrieval during subsequent use.

[0043] like Figure 6 As shown, the power supply 51 is fixed in the power supply compartment 5, and its output end is connected to the socket 23 by a wire, so that the power supply 51 supplies power to the socket 23.

[0044] The power supply compartment 5 also has a wire grid 6 on its side. A connection hole is provided between the wire grid 6 and the power supply compartment 5. The charging cable of the power supply 51 passes through this connection hole into the wire grid 6 and is stored there. The power supply 51 is charged using the charging cable. In on-site use, if the power supply 51 is low on power, only the charging cable needs to be pulled out and connected to a fixed power source. Centralized charging can be achieved with only one cable on-site, without interfering with maintenance work.

[0045] As a further preferred embodiment, the cabinet 1 is also provided with a handle 8 on its side for pushing the cabinet 1 to move.

[0046] As a further preferred embodiment, the cabinet 1 is also provided with a side tube 9, which has a cylindrical cavity for placing a fire extinguisher. This prevents fires during use and provides better safety.

[0047] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
