[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] Please refer to Figure 1 In one embodiment of the present invention, a side lock box disassembly device for a quay crane spreader is provided, comprising a disassembly tool for separating a side lock box assembly 200 from a side lock box housing 100;

[0025] In the embodiment of the present invention, both sides of the outer wall of the side lock box housing 100 are provided with hanging grooves 101 , and the hanging grooves 101 are matched with the disassembly tools.

[0026] like Figure 1-Figure 3 As shown, in a preferred embodiment of the disassembly tool provided by the present disclosure, the disassembly tool includes a bottom plate 300, both ends of the bottom plate 300 are connected to side plates 302, both ends of the side plates 302 are fixedly mounted with side plates 302, and a hook 303 is integrally formed on the inner side surface of the top end of the side plate 302, and the hook 303 cooperates with the hanging groove 101;

[0027] When the disassembly tool of the disclosed embodiment is used, the hook 303 is hung on the hanging groove 101. In the present invention, the specific structure of the hook 303 is not limited, and it only needs to cooperate with the hanging groove 101 to achieve a stuck state between the two.

[0028] Furthermore, the disassembly tool provided in the embodiment of the present disclosure also includes a jack 301 , and a top end of the jack 301 is fixedly provided with a plug 3011 , which is used to rest on the side lock box assembly 200 .

[0029] In this embodiment of the present invention, the jack 301 is fixedly mounted on the base plate 300 .

[0030] During specific use, the hooks 303 at the top of the two side panels 302 are respectively hung on the hanging grooves 101 on both sides of the side lock box shell 100, and then the extension of the jack 301 is controlled so that the head 3011 pushes and rests on the side lock box assembly 200. As the jack 301 continues to extend, the side lock box assembly 200 is pushed out of the side lock box shell 100.

[0031] Please continue reading Figure 1 and Figure 2 In the embodiment of the present utility model, the bottom end of the side panel 302 is integrally connected with a connecting plate 3021, and the connecting plate 3021 is fixedly connected to the end of the bottom plate 300 by a connecting bolt 304; wherein, the connecting plate 3021 and the end of the bottom plate 300 are both provided with bolt holes that match the connecting bolts 304, so that the connecting bolts 304 can be used to achieve a fixed connection between the connecting plate 3021 and the bottom plate 300.
