[0035] Next, the battery swapping device of the tire crane according to the embodiment of the present invention will be specifically described with reference to the accompanying drawings.

[0036] The battery swapping device of the tire crane according to the embodiment of the present invention, as Figure 1 shown, may include: a pair of guide rails 100, a battery assembly 200 and a driving mechanism 300.

[0037] Among them, a pair of guide rails 100 are used for relatively installing at the bottom of the saddle beam 400 of the rubber-tyred gantry crane. For example, a pair of guide rails 100 are relatively detachably arranged at the bottom of the saddle beam 400, and a pair of guide rails 100 are respectively arranged perpendicular to the extending direction of the guide rails 100 to maximize the utilization of the bottom space of the saddle beam 400.

[0038] The battery assembly 200 is movably arranged between a pair of guide rails 100.

[0039] The driving mechanism 300 is installed on the guide rail 100. The driving mechanism 300 connects the battery assembly 200 and the guide rail 100. The driving mechanism 300 is used to drive the battery assembly 200 to slide between a pair of guide rails 100 so that the battery assembly 100 can be removed from the bottom of the saddle beam 400 for battery replacement.

[0040] Specifically, for the battery replacement device of the rubber-tyred gantry crane according to the embodiment of the present utility model, by arranging a pair of opposite guide rails 100 at the bottom of the saddle beam 400, a pair of battery assemblies 200 are movably connected between the pair of guide rails 100 to facilitate the replacement of the battery assemblies 200. Among them, by arranging the driving mechanism 300 between the battery assembly 200 and the guide rail 100, it is used to stably drive the battery assembly 200 in and out of the bottom of the saddle beam 400. Thus, the battery of the rubber-tyred gantry crane can be replaced conveniently and reliably, which has the advantages of high efficiency, energy saving and environmental protection, and can effectively ensure the efficiency of the wharf operation.

[0041] In some embodiments, as Figure 2 shown, guide grooves 110 are respectively formed on the opposite side surfaces of a pair of guide rails 100, and the battery assembly 200 is movably connected to the guide grooves 110 of the pair of guide rails 100.

[0042] That is to say, guide grooves 110 along the length direction of the guide rails 100 are respectively formed on the opposite inner side surfaces of a pair of guide rails 100. Furthermore, the battery assembly 200 is movably connected to the pair of guide grooves 110. Through the limitation of the pair of guide grooves 110, the battery assembly 200 can move more stably and reliably at the bottom of the saddle beam 400.

[0043] In some embodiments, as Figure 1 and Figure 2 shown, the battery assembly 200 may include: a battery support frame 210 and a battery box 220.

[0044] Among them, both sides of the top of the battery support frame 210 are respectively movably connected to a pair of guide grooves 110.

[0045] The battery box 220 is detachably arranged in the battery support frame 210.

[0046] Specifically, the battery assembly 200 is provided with a battery support frame 210 and a battery box 220 detachably disposed within the battery support frame 210. On both sides of the top of the battery support frame 210, a pair of guide grooves 110 are movably connected, facilitating the battery box 220 to be installed at the bottom of the saddle beam 400 through the pair of guide grooves 110 when in a full-capacity state. When the battery power is insufficient, the battery assembly 200 is driven by the driving mechanism 300 to cause the battery support frame 210 to withdraw from the bottom of the saddle beam 400 along the pair of guide grooves 110 for battery replacement of the battery box 220.

[0047] In some embodiments, an opening (not shown) is formed at the top of the battery support frame 210 for the battery box 220 to enter and exit.

[0048] That is to say, by providing an opening at the top of the battery support frame 210 for the battery box 220 to enter and exit, it is convenient for the battery box 220 within the battery support frame 210 to be replaced through the opening. Among them, a switchable lid can also be provided on the opening to protect the battery box within the battery support frame 210 when battery replacement is not performed.

[0049] In some embodiments, as Figure 2 and Figure 3 shown, on the outer sides of both ends of the top of the battery support frame 210, a row of guide wheels 230 are respectively detachably installed, and the two rows of guide wheels 230 are respectively movably disposed within a pair of guide grooves 110.

[0050] That is to say, by installing a row of guide wheels 230 on the outer sides of the top of the battery support frame 210, and the two rows of guide wheels 230 are respectively disposed within a pair of guide grooves 110, the battery support frame 210 can be movably connected to a pair of guide rails 100, which is stable and reliable, and causes less wear and tear to the structure of the battery support frame 210 itself. Preferably, each row of guide wheels 230 includes at least three, and are respectively installed at both ends and the middle position on the side edge of the top of the battery support frame 210.

[0051] In some embodiments, as Figure 1 and Figure 2 shown, the driving mechanism 300 includes a first reduction motor 310 and a first rack 320.

[0052] Among them, the first reduction motor 310 is installed on the top of one side of the guide rail 100, the first rack 320 is correspondingly installed on the top side edge of the battery support frame 210 corresponding to the first reduction motor 310, and the output gear of the first reduction motor 310 meshes with the first rack 320.

[0053] That is to say, the driving mechanism 300 includes a first reduction motor 310 installed at the top of one side of the guide rail 100, and a first rack 320 correspondingly arranged on one side edge of the top surface of the battery carrier frame 210 opposite to the first reduction motor 310. The output gear of the first reduction motor 310 meshes with the first rack 320. Thus, by driving the output gear of the first reduction motor 310 to rotate forward and backward, the first rack 320 is driven to move along the direction of the guide rail 100, and further drive the entire battery carrier frame 210 to enter and exit the bottom of the saddle beam 400, which is convenient, stable and efficient.

[0054] In some embodiments, as Figure 1 shown, the driving mechanism 300 further includes a second reduction motor and a second rack.

[0055] The second reduction motor is installed at the top of the other side of the guide rail 100, and the second rack is correspondingly installed on one side edge of the top surface of the battery carrier frame 210 opposite to the second reduction motor. The output gear of the second reduction motor meshes with the second rack.

[0056] That is to say, on the guide rail 100 on the other side relative to the first reduction motor 310 and the first rack 320 and on one side edge of the top surface of the battery carrier frame 210, a second reduction motor and a second rack are respectively arranged, and the other side of the battery carrier frame 210 is driven to move relative to the guide rail 100 through the second reduction motor and the second rack. Thus, by adding the second reduction motor and the second rack to work synchronously with the first reduction motor 310 and the first rack 320, the stability of the movement of the large-weight battery assembly 200 in and out of the rubber-tyred gantry crane can be further ensured.

[0057] In some embodiments, as Figure 1 shown, the first rack 320 and the second rack are respectively arranged on one side edge of the top surface of the battery carrier frame 210 parallel to the corresponding guide rail 100.

[0058] This can ensure the smoothness of the movement of the battery carrier frame 210 in and out, and it is not easy to interfere and damage the components.

[0059] In some embodiments, the driving mechanism 300 further includes a controller (not shown), and the controller controls the synchronous operation of the first reduction motor 310 and the second reduction motor.

[0060] Thus, by the controller to control the coordinated operation of the first reduction motor 310 and the second reduction motor, the synchronism and accuracy of the operation of the first reduction motor 310 and the second reduction motor are further ensured.

[0061] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
