Abstract
The utility model discloses an automatic unhooking device for hoisting. The automatic unhooking device is composed of a hoisting ring and a hook, wherein the upper end of a suspension arm is fixedly provided with the hoisting ring, the hook is axially connected to the lower end of the suspension arm, a connecting rod is fixed at the upper end of the hook, a moment arm is fixed at the lower part of the suspension arm, the connecting rod is positioned above the moment arm, a tension spring is arranged between one end of the connecting rod and the moment arm, and the other end of the connecting rod is connected with a pull rope. The automatic unhooking device for hoisting has the characteristics of simple structure, convenience in operation, wide applicable height, simplicity and reliability in unhooking, high efficiency and low labor intensity.
Description
Technical field
The utility model belongs to hanging device technical field, especially designs a kind of lifting automatic decoupling device that knocks field for free-falling body.
Background technology
At present in object crushing process, adopting high-altitude weight free-falling body to clash into by the mode of pulverizing object is still widely used, the free-falling body of homogenous quantities, highly higher, the impulsive force of its generation is just larger, crushing effect is just better, but it is highly higher, and the weight lifting by crane by suspension hook breaks off relations more difficult; At present generally adopt electromagnetism and hydraulic pressure claw hook, but its complex structure, cost is high, and the quality of slinging is subject to design restriction, and safety is also difficult for ensureing, maintenance cycle is long.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of simple in structure, easy to operate, maxi-mum height extensively, the lifting automatic decoupling device simple and reliable, efficiency is high, labour intensity is low breaks off relations.
The purpose of this utility model is to realize like this, a kind of lifting automatic decoupling device, formed by suspension ring and suspension hook, the upper end that is characterized in arm is fixed with suspension ring, and suspension hook axle is connected to the lower end of arm, and the upper end of suspension hook is fixed with connecting rod, the arm of force is fixed on the bottom of arm, connecting rod is positioned at the top of the arm of force, between one end of connecting rod and the arm of force, is provided with extension spring, and the other end of connecting rod is connected with stay cord.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts the upper end of arm to be fixed with suspension ring, suspension hook axle is connected to the lower end of arm, the upper end of suspension hook is fixed with connecting rod, the arm of force is fixed on the bottom of arm, connecting rod is positioned at the top of the arm of force, between one end of connecting rod and the arm of force, be provided with extension spring, the other end of connecting rod is connected with stay cord, rotate along axle to suspension hook by stay cord power transmission, when suspension hook rotates to certain angle to unhook position, weight nature comes off from suspension hook, can be according to the needs of different impulsive forces, reach certain sling height, by the change to pulling rope length, or by changing the substance quality of free-falling body, meet necessary requirement, and simple and reliable, efficiency is high, labour intensity is low, this apparatus structure is simple and practical, safe and reliable, environmental protection, and production efficiency is high, and labour intensity is low, simple to operate, can be widely used in brittle crush field.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Embodiment, a kind of lifting automatic decoupling device, with reference to Fig. 1, be that the upper end of arm 4 is fixed with suspension ring 1, suspension hook 2 axles are connected to the lower end of arm 4, the upper end of suspension hook 2 is fixed with connecting rod 5, the arm of force 6 is fixed on the bottom of arm 4, and connecting rod 5 is positioned at the top of the arm of force 6, between one end of connecting rod 5 and the arm of force 6, is provided with extension spring 3, the other end of connecting rod 5 is connected with stay cord 7, and this forms a kind of structure of the present utility model.
