[0020] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with the specific embodiments and corresponding drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0021] As Figures 1 to 2 shown, the emergency control box of the crane of the present utility model includes a box body 1, a relay 2, a switch 3, and a plug-in 4, where:

[0022] The relay 2 is arranged inside the box body 1, the switch 3 is arranged on one side of the box body 1, and the plug-in 4 is arranged at one end of the box body 1 and is respectively connected to the relay 2 and the switch 3;

[0023] The plug-in 4 includes an A plug-in 41 and a B plug-in 42, and the A plug-in 41 and the B plug-in 42 are arranged side by side.

[0024] Further, in the emergency control box of the crane of the present utility model, there are four switches 3, all of which are two-position self-locking switches. One of the switches 3 is a spare switch 3. Thus, after one of the switches 3 fails, it can be replaced by the spare switch 3, thereby avoiding the problem of overall replacement due to the damage of the switch 3 during long-term use. The control ends of the other three switches 3 are connected to the output terminal of the B plug-in 42, effectively ensuring that the equipment can perform emergency operations by controlling the switch 3.

[0025] Further, in the emergency control box of the crane of the present utility model, the input end of the relay 2 is connected to the input terminal of the B plug-in 42, and the output end of the relay 2 is respectively connected to the output terminals of the A plug-in 41 and the B plug-in 42. Thus, the emergency control box can perform corresponding actions by inputting a control signal without programming.

[0026] Further, in the emergency control box of the crane of the present utility model, the A plug-in 41 adopts the plug-in of model 776087-1, and the B plug-in 42 adopts the plug-in of model 776163-1, so that the models of the A plug-in 41 and the B plug-in 42 are the same as those of the original controller plug-in, ensuring interchangeability.

[0027] Further, in the emergency control box of the crane of the present utility model, the box body 1 is bent from a carbon steel plate with a thickness of 1.5 mm. The bending size of the box body 1 can be the same as that of the original controller, so as to ensure that the box body 1 can be embedded in the installation slot of the original controller.

[0028] Specifically, when replacing the original controller with the emergency control box of the new crane, the original controller is pulled out. At this time, the control cable is inserted into the corresponding A plug-in 41 and B plug-in 42, realizing plug-and-play. As Figure 3 shown, the lifting of the crane can be controlled by controlling the switch 3. At the same time, by inputting corresponding control signals to the input end of the B plug-in 42 and processing them by the relay 2, corresponding action signals are output to the output ends of the A plug-in 41 and the B plug-in 42, so as to control the crane and replace the original controller to work.

[0029] To sum up, compared with the prior art, the emergency control box of the crane of the present utility model has the following advantages and beneficial effects:

[0030] The overall structure is simple and the cost is low. By connecting the A plug-in and the B plug-in with the relay and the switch, it can control the crane instead of the controller without programming, realizing plug-and-play, effectively reducing the maintenance cost, and at the same time reducing the maintenance time after the controller is damaged.

[0031] It should be noted that in this article, unless otherwise clearly stipulated and defined, the term "connection" or its synonyms should be understood in a broad sense. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific circumstances. Moreover, expressions such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. At the same time, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. In addition, in this article, "front", "rear", "left", "right", "upper" and "lower" are all referred to the placement state shown in the drawings.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
