Description

Technical Field

[0001] This utility model relates to container cranes, and more specifically, to a power swapping device for container cranes. Background Technology

[0002] Container terminals are moving towards a clean, energy-efficient, and environmentally friendly future, with battery power becoming a key trend. To address the challenge of battery range, battery swapping technology has emerged, providing a new power solution for terminal operations.

[0003] Current battery swapping methods: The base for connecting the battery terminal plug of the battery cabinet to the vehicle terminal socket is generally designed as an integral or separate unit with internal guidance. The disadvantage of the integral type is that it occupies a large space and is heavy, which is not conducive to the modification of existing port designs. The separate type with internal guidance has higher requirements for the manufacturing of the battery cabinet. Generally, under the condition of length restrictions (port cranes have strict length restrictions), the battery cabinet can only be increased in height to meet the internal guidance requirements. The extra-height battery cabinet will affect the lifting height of the modified equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a power swapping device for container cranes, which not only improves operating efficiency but also significantly reduces environmental burden.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] The first bracket is mounted on the product and fixed to the battery cabinet by a first locking mechanism;

[0036] To better understand the above-mentioned technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Combination Figures 1 to 9 As shown, the present invention provides a battery swapping device for a container crane, comprising a first guide assembly 2, a second guide assembly 5, and a battery swapping connector docking mechanism 4.

[0038] The battery swapping connector docking mechanism 4 includes a battery-side electrical connector 401, a vehicle-side electrical connector 402, a mounting plate 409, and a flexible mechanism.

[0039] The battery terminal connector 401 is fixed on the battery cabinet 3.

[0040] The vehicle-side electrical connector 401 is electrically connected to the battery-side electrical connector 402 and is supported by the mounting plate 409.

[0041] Two sets of elastic mechanisms are provided and symmetrically connected to the mounting plate 409. Each set includes a shaft 405, a cotter pin 404, a spring 408, a lubrication sleeve 407, a washer 406, and two nuts 403 and 410.

[0042] The upper end of shaft 405 passes through mounting plate 409 and is positioned and connected by a nut 410.

[0043] The end of shaft 405 passes through product 1 and is positioned and connected by another nut 403 and cotter pin 404.

[0044] Lubricating sleeve 407 and gasket 406 are fitted onto shaft 405 and come into contact with product 1.

[0045] Spring 408 is fitted onto lubrication sleeve 407.

[0046] When the spring 408 returns to its free state, it pulls the mounting plate 409 to prevent it from detaching from product 1.

[0047] The lubrication sleeve 407 is used to ensure that the shaft 405 is not damaged and to reduce friction.

[0048] The first guide assembly 2 includes a first bracket 203, a first guide shaft 202, and a first locking mechanism 204.

[0049] The first bracket 203 is mounted on the product 1 and fixed to the battery cabinet 3 by the first locking mechanism 204.

[0050] The first guide shaft 202 is mounted on the first bracket 203.

[0051] The first guide shaft 202 serves as a coarse guide for the battery-side electrical connector 401 and the vehicle-side electrical connector 402. The length of the first guide shaft 202 is equal to the guide length of the vehicle-side electrical connector 402 plus the buffer length of the spring 408 plus 50mm.

[0052] To compensate for forklift positioning errors, the first bracket 203 is equipped with length and width position guides, so that the battery cabinet 3 can be smoothly placed onto product 1.

[0053] Bolt 205 secures the first bracket 203 to product 1.

[0054] The second guide assembly 5 includes a second bracket 501, a second guide shaft 502, and a second locking mechanism 504.

[0055] The second bracket 501 is mounted on the product 1 and fixed to the battery cabinet 3 by the second locking mechanism 504.

[0056] The second guide shaft 502 is mounted on the second bracket 502.

[0057] The function of the second guide assembly 5 is basically suppressed by the function of the first guide assembly 2. The difference is that the second bracket 501 of the second guide assembly 5 is used to support the battery swapping connector docking mechanism 4.

[0058] Both the first bracket 203 and the second bracket 501 are equipped with buffer blocks 201 and 503. The buffer blocks 201 and 503 are designed according to the product weight to ensure that the battery cabinet 3 has sufficient buffering force to offset the impact on the product 1.

[0059] Both the first locking mechanism 204 and the second locking mechanism 504 include a locking shaft 20401, a spring pin 20402, a spring 20403, and a cover 20404.

[0060] The first locking mechanism 204 and the second locking mechanism 504 are similar to tractor gear shifting mechanisms. The locking shaft 20401 and the spring 20403 are respectively installed in the first bracket 203 and the second bracket 501. The spring pin 20402 and the cover 20404 block the locking shaft 20401 so that it cannot fall off. The locking can be achieved by moving the locking shaft 20401.

[0061] The primary function of the first locking mechanism 204 and the second locking mechanism 504 is to secure the battery cabinet 3 and prevent it from falling off during tilting. Their components form a spring-compression locking mechanism, which can be manually unlocked or locked.

[0062] This utility model of battery swapping device utilizes a guiding principle similar to that of a container falling into a ship's hold, combined with a spring buffer mechanism and rubber buffer, to reduce the impact of battery swapping under complex working conditions, providing a solution for battery swapping of industrial products.

[0063] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
