Description

Technical Field

[0001] This invention relates to the field of intelligent rail transit vehicle installation technology, and in particular to an overall installation hoist for the power battery of an intelligent rail transit vehicle, and a method for overall installation of the power battery using the hoist. Background Technology

[0002] The power battery system of intelligent rail transit vehicles mainly includes components such as power batteries, brackets, pipelines, and wiring harnesses. The current mainstream assembly process is as follows: first, install the battery brackets; then, use lifting equipment to hoist the batteries one by one; finally, connect the pipelines and wiring harnesses. However, the assembly process of the power battery system components can only be carried out along the main line, resulting in long main line operation times, poor line balance, and inherent dangers associated with working at heights. Furthermore, the lifting equipment can only hoist batteries one by one, leading to low assembly efficiency. In addition, the lifting equipment can only accommodate power batteries of the same model, resulting in poor assembly flexibility. Moreover, the large size of the lifting equipment makes it difficult to store. Summary of the Invention

[0041] The power battery system of intelligent rail transit vehicles mainly includes components such as power batteries, brackets, pipelines, and wiring harnesses. The current mainstream assembly process is as follows: first, install the battery brackets; then, use lifting equipment to hoist the batteries one by one; finally, connect the pipelines and wiring harnesses. However, the assembly process of the power battery system components can only be carried out along the main line, resulting in long main line operation times and poor line balance; and the lifting equipment can only hoist the batteries one by one, leading to low assembly efficiency.

[0042] This invention provides an integrated lifting tool for a power battery system, which can lift the power battery and its brackets, pipes, wiring harnesses and other auxiliary parts in one go, greatly improving work efficiency; it can adapt to the assembly of different models and any number of power batteries, and has high assembly flexibility.

[0043] The present invention also provides a method for the overall installation of a power battery system using the above-mentioned lifting tool, which greatly saves the main line operation time and can also improve line balance.

[0044] Figure 1 This invention illustrates a pre-assembled component for a smart rail transit vehicle's power battery system according to an embodiment of the present invention. The present invention assembles the smart rail transit vehicle's power battery system offline in advance. The following is an illustration. Figure 1 As shown, the power battery system of the intelligent rail transit vehicle includes, but is not limited to, battery bracket 1, No. 1 power battery 2, No. 2 power battery 3, No. 3 power battery 4, No. 4 power battery 5, first water pipe assembly 6, second water pipe assembly 7, first wiring harness assembly 8, second wiring harness assembly 9, third wiring harness assembly 10, fourth wiring harness assembly 11, and fifth wiring harness assembly 12.

[0045] Figure 2 The present invention illustrates the pre-installation process of a power battery system for a smart rail transit vehicle according to an embodiment of the present invention.

[0046] Step 201: Power battery installation.

[0047] Step 202: Piping installation.

[0048] Step 203: Wiring harness installation.

[0049] Step 204: Overall hoisting.

[0050] First, individual battery hoists are used to lift each battery onto the battery bracket and secure them with bolts; then, the piping is connected; and finally, the wiring harness is connected. At this point, the pre-installation of the intelligent rail transit vehicle's power battery system is complete.

[0051] Finally, the pre-assembled assembly was lifted onto the roof of the vehicle and secured using a battery hoist.

[0052] Figure 3 A formal diagram of a lifting device structure according to an embodiment of the present invention is shown. Figure 4 A side view of a lifting device structure according to an embodiment of the present invention is shown.

[0053] The lifting beam adopts a split design: before hoisting, the left lifting beam 301 and the right lifting beam 302 are connected as a whole by fasteners 303; the upper part of the lifting beam is equipped with upper lifting lugs 304, which are welded to the four corners of the lifting beam to maintain balance, and are connected to the hook of the lifting equipment through slings 307; the lower part of the lifting beam is equipped with multiple lower lifting lugs 305, which are movable hanging sleeves. They can be fixed to the holes reserved on the lifting beam according to the number and model of the batteries, ensuring that the slings are vertical during hoisting and do not interfere with the battery shell; the lower lifting lugs are connected to the special hooks 308 through shackles 306 and slings 307, and the special hooks are then connected to the battery hoisting holes.

[0054] Specifically, such as Figure 3and 4 As shown, the main components of the lifting device include the left lifting beam 301, the right lifting beam 302, the fastener 303, the upper lifting lug 304, the lower lifting lug 305, the shackle 306, the sling 307, and the hook 308.

[0055] The left lifting beam 301 is connected to the right lifting beam 302 as a whole by fasteners 303.

[0056] The upper lifting lug 304 is installed above the lifting beam.

[0057] In one embodiment, the upper lifting lugs 304 are welded to the four corners of the lifting beam to maintain balance.

[0058] In one embodiment, the upper lifting lug 304 can also be set in other locations, such as a main lifting lug set in the center of the lifting beam, to achieve the same effect.

[0059] The sling 307 is connected to the hook 308 of the lifting equipment.

[0060] In one embodiment, the sling portion can also be replaced with a chain or similar structure to achieve the same purpose.

[0061] Multiple lower lifting lugs 305 are installed at the bottom of the lifting beam. These lugs are movable hanging sleeves, and can be fixed to pre-drilled holes on the lifting beam according to the number and model of the batteries, ensuring the slings remain vertical during hoisting and do not interfere with the battery casing. The lower lifting lugs 305 are connected to hooks 308 via shackles 306 and slings 307, and the hooks 308 are then connected to the battery hoisting holes.

[0062] In one embodiment, the lower lifting lug 305 employs a movable sliding sleeve structure design. Alternatively, holes can be evenly distributed on the lifting beam, and butterfly clips or similar installation methods can be used to achieve the same effect.

[0063] In one embodiment, in order to reliably connect the power battery, the hook 308 part can be a dedicated hook, or other similar forms (such as standard hooks, shackles, etc.) can be selected, all of which can achieve the same effect.

[0064] It should be noted that the lifting beam of the present invention adopts a left-right split design, which can be disassembled and stored easily. It can also be set to other forms of split design to achieve the same purpose.

[0065] In order to meet the load-bearing requirements of the lifting device, the lifting beam can adopt various forms of hangers (such as I-beams, circular lifting beams, etc.). Alternatively, it can be designed as a split lifting device to reduce volume and facilitate storage. The same effect can be achieved by manually assembling it during use.

[0066] The lifting device of the present invention has extremely beneficial technical effects:

[0067] Firstly, the pre-installation method of the power battery system in this invention (that is, pre-assembling the battery, bracket, wiring harness and pipeline offline, and then hoisting the whole system onto the roof of the vehicle for fixation) can greatly save the main line operation time and help improve line balance.

[0068] Secondly, the lifting device in this invention can lift the pre-assembled components of the power battery system in one go (that is, the lifting device can lift any number of batteries and their brackets, wiring harnesses, pipes and other auxiliary parts at the same time), which greatly improves the work efficiency;

[0069] Third, the lifting device in this invention can adapt to the installation of different quantities and models of power batteries, and has high assembly flexibility;

[0070] Fourth, the lifting device in this invention is detachable and easy to store, occupies a small area, and can be manually assembled before use.
