Description

Technical Field

[0001] This utility model relates to the technical field of rail transit vehicle battery maintenance equipment, specifically a tray-type integrated battery module quick maintenance tool for rail transit. Background Technology

[0002] The main functions of battery modules on rail vehicles are reflected in three aspects: First, they serve as backup power for emergency startup and power supply for onboard loads (such as lighting, pantographs, etc.); second, they serve as traction power in areas without power grids or when the traction grid is down, i.e., they use battery energy storage systems to power the train to continue running, which reduces the need for power supply facilities. In addition, in vehicles with low power requirements, the energy storage battery system can provide the power; third, they absorb regenerative energy during train braking.

[0003] However, existing rail vehicle battery modules are large and heavy, making traditional manual disassembly and assembly inefficient and posing safety hazards. Integrated tray-type battery modules have complex structures, making disassembly and maintenance cumbersome and requiring multiple people to work together. Existing maintenance tools lack specificity, easily leading to battery interface damage or positioning errors. Therefore, the development of a rapid maintenance fixture for tray-type integrated battery modules used in rail transit is urgently needed. This equipment can quickly disassemble, assemble, maintain, and repair tray-type integrated battery modules during vehicle parking and maintenance, which is a crucial element for ensuring normal vehicle operation.

[0016] The lower part of the maintenance tool frame 2 is equipped with multiple lifting and adjusting feet 5.

[0017] The working process of this tray-type integrated battery module for rail transit quick maintenance is as follows:

[0018] Step 1: Build the maintenance fixture frame 2 on the front of the battery box 1, install the maintenance tray 4 on the bracket provided on the maintenance fixture 2 at a suitable height, and adjust the lifting adjustment feet 5 until the maintenance tray 4 and the bottom frame of the tray-type integrated battery module 3 being maintained are on the same horizontal plane.

[0019] Step 2: Adjust the first limiting block 42 and the second limiting block 43 on the maintenance tray 4 to reserve the fixed position of the tray-type integrated battery module 3 on the maintenance tray 4, so as to facilitate positioning the reserved tray-type integrated battery module 3 in the middle of the maintenance tray 4.

[0020] Step 3: Adjust the locking mechanism 6 on the maintenance tool frame 2 to fix the locking mechanism 6 to the battery box 1;

[0021] Step 4: Pull the tray-type integrated battery module 3 out of the battery box 1, slide it onto the maintenance tray 4 via the roller 41, and lock the first limit block 42 and the second limit block 43 to fix the tray-type integrated battery module 3.

[0022] Step 5: After the maintenance and repair work is completed, release the locked first limit block 42 and second limit block 43, push the tray-type integrated battery module 3 back into the battery box 1 and fix it; remove the maintenance tray 4 from the bracket and release the locking mechanism 6 to remove the maintenance tooling.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 2 As shown, this utility model provides a quick maintenance fixture for tray-type integrated battery modules used in rail transit. The fixture includes a maintenance frame 2 that matches the battery housing 1. The frame 2 has multiple layers of supports for mounting and fixing a maintenance tray 4. Multiple rollers 41 are provided on both sides of the maintenance tray 4 for sliding the tray-type integrated battery module 3 onto the tray 4. The frame of the maintenance tray 4 also has multiple first limiting blocks 42 and multiple second limiting blocks 43, which are used to position the tray-type integrated battery module 3 on the maintenance tray. Preferably, the first limiting blocks 42 and the second limiting blocks 43 can be connected to the maintenance tray 4 via ball bearing guides.

[0032] The bottom of the maintenance tool frame 2 is equipped with multiple lifting and adjusting feet 5, which are used to finely adjust the height of the maintenance tray 4 so that the maintenance tray 4 matches the position of the tray-type integrated battery module 3 that needs to be maintained.

[0033] The maintenance tooling frame is also equipped with a locking mechanism 6 that can be fixedly connected to the battery box to ensure the stability of the tray-type integrated battery module 3 that needs maintenance when it slides to the maintenance tray 4.

[0034] During operation, the maintenance fixture frame 2 is erected on the front of the battery box 1. The maintenance tray 4 is installed on the bracket provided on the maintenance fixture 2 at a suitable height. The lifting adjustment feet 5 are adjusted until the maintenance tray 4 and the bottom frame of the tray-type integrated battery module 3 being maintained are on the same horizontal plane. The first limit block 42 and the second limit block 43 on the maintenance tray 4 are adjusted to reserve a fixed position for the tray-type integrated battery module 3 on the maintenance tray 4, so as to facilitate positioning the reserved tray-type integrated battery module 3 in the middle of the maintenance tray 4. The fixing plate of the locking mechanism 6 on the maintenance fixture frame 2 is adjusted to fix the locking mechanism 6 to the battery box 1. Optionally, An auxiliary support 7 can be installed on the maintenance fixture frame 2 to support the outer portion of the maintenance tray 4 relative to the maintenance fixture 2. The tray-type integrated battery module 3 is pulled out from the battery box 1 and slid onto the maintenance tray 4 via the roller 41. The first limiting block 42 and the second limiting block 43 are locked to fix the tray-type integrated battery module 3. After the maintenance and repair work is completed, the locked first limiting block 42 and the second limiting block 43 are released, and the tray-type integrated battery module 3 is pushed back into the battery box 1 and fixed. The maintenance tray 4 is removed from the bracket, the locking mechanism 6 is released to remove the maintenance fixture, and the maintenance and repair work is completed.
