Technical field
It is risen the present invention relates to one kind and reuses overload protection device.
Background technology
Crane refers to more action hoisting machineries of vertical-lift in a certain range and horizontal carrying heavy goods, extensive use
In fields such as machinery, chemical industry, the energy.The one kind of electric block as lifting equipment, because its with it is small, from heavy and light, operation
The features such as simple and easy to use, it is widely used in the places such as operating mode enterprise, warehousing wharf.Electric block is super in order to prevent
It carries, generally installs overload protection device additional on electric block, but these devices can not lift row overload of advancing in electric block
Prompting, but just know overload after electric gourd hang plays weight, electric block is because born the weight of overload at this time
Object can if things go on like this damage electric block, shorten the service life of electric block.
Invention content
The present invention overcomes the deficiencies in the prior art, provide a kind of simple in structure rising and reuse overload protection device.
In order to achieve the above objectives, the technical solution adopted by the present invention is：One kind rise reuse overload protection device, including girder,
Electric block ontology on the girder and the reel on the electric block ontology are twined on the reel
Steel wire rope is wound with, the steel wire rope is connected with hook assembly, and the hook assembly includes shell, the dynamic cunning with the cage connection
Wheel and suspension hook, the shell include outer cover body, the support plate on the outer cover body, controller and display screen, institute
It states support plate to include support plate ontology, be fixed on multiple support feets of the support plate ontology bottom end, in the support plate ontology
At least one weight sensor is provided with, the display screen, at least one weight sensor are connected with the controller, institute
The bottom for stating suspension hook is equipped with universal wheel.
In a preferred embodiment of the present invention, rise and reuse the quantity that overload protection device further comprises the weight sensor
It it is four, four weight sensors are separately positioned on the surrounding of the support plate ontology.
In a preferred embodiment of the present invention, play reuse overload protection device and further comprise the movable pulley and outer cover body
Between be connected with fulcrum, the fulcrum passes through the support plate ontology, and the fulcrum is consolidated close to the end of the support plate ontology
Surely there is block.
In a preferred embodiment of the present invention, play reuse overload protection device and further comprise that the support plate ontology is in water chestnut
Shape.
In a preferred embodiment of the present invention, play reuse overload protection device and further comprise being equipped on the outer cover body
Warning lamp, the warning lamp are connected with the controller.
In a preferred embodiment of the present invention, play reuse overload protection device and further comprise that the warning lamp is acousto-optic warning
Lamp.
The present invention solves defect present in background technology, the configuration of the present invention is simple, easy to use, passes through universal wheel
Slide be convenient for by shell toward on side partially, it is time saving and energy saving so as to keep flat on the ground, it is convenient and efficient, simultaneously because outer cover body has
There is certain thickness, thus the distance between support plate ontology and ground can be caused to be balanced by multiple support feets, carried
Height treats the accuracy that lifting object is weighed, and avoids erroneous judgement, improves working efficiency, while lifting object progress is just treated before lifting
The judgement of weight prevents from overloading, and avoids the damage to electric block, extends the service life of electric block.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the preferred embodiment of the present invention；
Fig. 2 is that the support plate of the preferred embodiment of the present invention keeps flat front view on the ground.
Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure only illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention in a schematic way.
As shown in Figure 1 and Figure 2, a kind of rise reuses overload protection device, the electronic calabash including girder 10, on girder 10
Lu Benti 12 and the reel 14 on electric block ontology 12 are wound with steel wire rope 16 on reel 14, and steel wire rope 16 connects
Hook assembly is connected to, hook assembly includes shell 18, the movable pulley 20 being connect with shell 18 and suspension hook 22, and shell 18 includes shell
Ontology 24, the support plate 26 on outer cover body 24, controller 28 and display screen 30, support plate 26 include support plate ontology
32nd, multiple support feets 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 slip of universal wheel 38 be convenient for by shell 18 toward on side partially, it is time saving and energy saving so as to keep 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 caused to pass through
Multiple support feets 34 are balanced, and the accuracy that lifting object is weighed is treated in raising.
The quantity of preferred weight sensor 36 of the present invention is four, and four weight sensors 36 are separately positioned on support plate sheet
The surrounding of body 32 further improves the accuracy weighed.
Of the invention that fulcrum 40 is preferably connected between movable pulley 20 and outer cover body 24, fulcrum 40 passes through support plate ontology
32, fulcrum 40 is fixed with block 42, support plate ontology 32 and 24 pin joint of outer cover body close to the end of support plate ontology 32, in this way
Facilitate the adjustment that position is carried out to support plate ontology 32, the interference that suspension hook 22 is avoided to lift weight.
Preferably support plate ontology 32 of the invention assumes diamond in shape, and avoids the interference to steel wire rope 16, while convenient in support plate sheet
It is placed on body 42 and treats lifting object.
In order to timely inform operating personnel, warning lamp 44, warning lamp 44 are installed on the present invention preferably outer cover body 24
It is connected with controller 28.Further preferred warning lamp 44 is acousto-optic warning lamp, good warning effect.
In the use of the present invention, pulling suspension hook 22 toward drop-down, the setting of 22 Universal wheel at bottom 38 of suspension hook causes shell 18
On toward side partially, shell 18 is kept flat on the ground, will treat that lifting object is placed on support plate ontology 32, and four weight sensors 36 will
The weight signal of acquisition passes to controller 28, and weight is shown on the display 30, if not overloading, by 22 hook of suspension hook
It firmly treats lifting object, steel wire rope 16 is driven to move up by reel 14；If overload, warning lamp 44 send out sound-light alarm.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
The content being not limited on specification, it is necessary to determine the technical scope according to the scope of the claims.
