In one preferred embodiment of the utility model, it is acousto-optic that a reuse overload protection device, which further comprises the warning lamp,
Warning lamp.
The utility model solves defect present in background technique, and the utility model structure is simple, easy to use, passes through
The sliding of universal wheel be convenient for by shell toward on side partially, it is time saving and energy saving to lay flat on the ground, it is convenient and efficient, simultaneously because outside
Shell ontology has certain thickness, thus the distance between support plate ontology and ground can be made to carry out by multiple support legs
Balance improves the accuracy for treating lifting object weighing, avoids erroneous judgement, improves working efficiency, while just treating and hanging before lifting
The judgement that object carries out weight is filled, prevents from overloading, avoids the damage to electric block, extend the service life of electric block.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the main view of the preferred embodiment of the utility model；
Fig. 2 is that the support plate of the preferred embodiment of the utility model lays flat main view on the ground.
Specific embodiment
The utility model is described in further detail presently in connection with drawings and examples, these attached drawings are simplified
Schematic diagram only illustrates the basic structure of the utility model in a schematic way, therefore it only shows structure related with the utility model
At.
As shown in Figure 1 and Figure 2, a kind of rise reuses overload protection device, including girder 10, the electronic calabash being mounted on girder 10
Lu Benti 12 and the reel 14 being mounted on electric block ontology 12, wirerope 16 is wound on reel 14, and wirerope 16 connects
It is connected to hook assembly, hook assembly includes shell 18, the movable pulley connecting with shell 18 20 and suspension hook 22, and shell 18 includes shell
Ontology 24, the support plate 26 being mounted on outer cover body 24, controller 28 and display screen 30, support plate 26 include support plate ontology
32, multiple support legs 34 of 32 bottom end of support plate ontology are fixed on, at least one weight sensing is provided in support plate ontology 32
Device 36, display screen 30, at least one weight sensor 36 are connected with controller 28, and the bottom of suspension hook 22 is equipped with universal wheel
38, by the sliding of universal wheel 38 be convenient for by shell 18 toward on side partially, it is time saving and energy saving to lay flat on the ground, it is convenient and efficient,
Simultaneously because outer cover body 24 has certain thickness, thus the distance between support plate ontology 32 and ground can be made to pass through
Multiple support legs 34 are balanced, and improve the accuracy for treating lifting object weighing.
The quantity of the utility model preferred weight sensor 36 is four, and four weight sensors 36 are separately positioned on support
