Abstract
The utility model discloses a mobile crane with an automatic weight limiting function. The mobile crane comprises a left upright post, a transverse girder and a right upright post, wherein the left upright post and the right upright post are fixedly connected with the transverse girder by a left inclined support frame and a right inclined support frame respectively; road wheels are arranged at the bottom ends of the left upright post and the right upright post; a motor is fixed on the transverse girder; a lifting hook is connected with the motor through a steel rope; the lifting hook is provided with a weighing sensor, and the controller is provided with a control circuit connected with the weighing sensor and the motor. Compared with the common crane, the mobile crane with the automatic weight limiting function has the advantages that the design is reasonable; and the weighing sensor and the controller are additionally arranged on the mobile crane, so that the overload of the crane can be effectively avoided, and accidents are also reduced.
Description
Technical field
The utility model relates to a kind of movable crane, is specifically related to a kind of movable crane with automatic weight limiting function.
Background technology
Crane is important tool and the equipment of realizing production process mechanization, automation in modern industry production and the lifting transportation, and it is widely used in the handling of material in workshop, warehouse and the stock ground, can alleviate manual labor, raises labour productivity.Because crane belongs to special equipment, in use presses code requirement, do not allow overload to surpass and hang overweight thing.But in daily production process, use the crane overloading of common occurrence, overload very easily causes the generation of safety misadventure, causes the loss of property, even personnel's injures and deaths.
The utility model content
Technical problem to be solved in the utility model provides a kind of movable crane with automatic weight limiting function that effectively prevents overload operation.
For solving the problems of the technologies described above, a kind of movable crane with automatic weight limiting function of the present utility model, comprise left column, horizontal girder and right column, left diagonal ligament frame is captiveed joint with right column left column respectively with right diagonal ligament frame with horizontal girder, the bottom of described left column and right column is equipped with road wheel, electrical motor is fixed on the described horizontal girder, suspension hook is connected with described electrical motor by steel cable, described suspension hook is provided with LOAD CELLS, and controller is provided with control circuit and links to each other with electrical motor with described LOAD CELLS.
In time warn the ground personage when crane overloads, above-mentioned controller is provided with buzzer phone and warning indicator lamp.
For guaranteeing the fastness of crossbeam, above-mentioned horizontal girder is steel pipe.
Compared with prior art, the beneficial effect that the utlity model has is: the utility model is provided with LOAD CELLS at suspension hook, when article overweight the safety value of setting, controller sends caution, electrical motor stops the handling article, thereby has effectively avoided the crane overload, has reduced safety misadventure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural representation with movable crane of automatic weight limiting function of the utility model.
The specific embodiment
As shown in Figure 1, a kind of movable crane with automatic weight limiting function, comprise left column 1, horizontal girder 2 and right column 6, left diagonal ligament frame 3 is captiveed joint with right column 6 left column 1 respectively with right diagonal ligament frame 4 with horizontal girder 2, the bottom of described left column 1 and right column 6 is equipped with road wheel 7, electrical motor 5 is fixed on the described horizontal girder 2, suspension hook 8 is connected with described electrical motor 5 by steel cable, described suspension hook 8 is provided with LOAD CELLS, and controller 9 is provided with control circuit and links to each other with electrical motor 5 with described LOAD CELLS.During the handling article, when the weight of article during greater than the setting value of controller 9, LOAD CELLS on the suspension hook 8 is passed to controller 9 with signal, buzzer call, warning indicator lamp that controller 9 is provided with are glittering, the caution Near Ground personnel leave, and blocks power supply with Time Controller 9, and electrical motor 5 is out of service, thereby effectively avoided the crane overload, reduced safety misadventure.
