Abstract
The invention discloses a chain hoist with an overload protection device. The chain hoist comprises a chain hoist body and a hook frame. A hook is arranged at the bottom of a steel frame, the upper portion of the hook frame is hinged to the bottom of the chain hoist body, the hinge portion is provided with a sensing pin shaft, and the sensing pin shaft is connected with a sensor lead. Compared with the prior art, the chain hoist body and the hook are provided with the pin shaft, a sensor is disposed on the pin shaft so as to directly sense the hoisting weight of the chain hoist, reaction is sensitive, and the chain hoist has the function of sensing chain sticking and overload faults.
Description
Technical field
The present invention relates to ring-chain hoist overload protection device, particularly a kind of ring-chain hoist that has overload protection.
Background technology
The ring-chain hoist overload protection device using is at present outer joining all, general, is all generally tabular, and volume is large, and cost is high.
Summary of the invention
The object of the invention is to provide a kind of ring-chain hoist that has overload protection.
For achieving the above object, the present invention implements according to following technical scheme:
A ring-chain hoist that has overload protection, comprises ring-chain hoist main body, hook housing, and steelframe bottom is provided with suspension hook, and described hook housing top and ring-chain hoist bottom part body are hinged, and hinged place arranges sensing bearing pin, on described sensing bearing pin, is connected with sensor lead.
Further, the top of described suspension hook is fixedly connected with hook housing bottom by the suspension hook sensing bearing pin arranging, and on suspension hook sensing bearing pin, is connected with sensor lead.
As preferably, sensor lead is drawn with one end from sensing bearing pin and suspension hook sensing bearing pin.
Compared with prior art, ring-chain hoist body of the present invention and suspension hook have assembling bearing pin, and the present invention loads onto sensor this bearing pin, and directly perception ring-chain hoist hoisting weight, is quick on the draw, and have the function of perception chain jamming overload fault.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-ring-chain hoist main body, 2-sensing bearing pin, 3-hook housing, 4-bearing pin sensor lead, 5-suspension hook sensing bearing pin, 6-suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described, in illustrative examples and the explanation of this invention, is used for explaining the present invention, but not as a limitation of the invention.
The ring-chain hoist that has overload protection as shown in Figure 1; comprise ring-chain hoist main body 1, hook housing 3, steelframe 3 bottoms are provided with suspension hook 6, described hook housing 3 tops and ring-chain hoist main body 1 bottom-hinged; hinged place arranges sensing bearing pin 2, on described sensing bearing pin 2, is connected with sensor lead 4.
Further, the top of described suspension hook 6 is fixedly connected with hook housing 3 bottoms by the suspension hook sensing bearing pin 5 arranging, and on suspension hook sensing bearing pin 5, is connected with sensor lead 4.
Further, sensor lead 4 is drawn with one end from sensing bearing pin 2 and suspension hook sensing bearing pin 5.
Ring-chain hoist main body 1 is by sensing bearing pin 2 and hook housing 3 hinge joints, hook housing 3 upwards has suspension hook sensing bearing pin 5 and suspension hook 6 hinge joints, during ring-chain hoist work, the pulling force that connects chain in ring-chain hoist main body 1 is passed to sensing bearing pin 2 and hook housing 3, hook housing 3 is passed to suspension hook sensing bearing pin 5 the total pulling force of chain (gravity of weight), when weight is overweight, suspension hook sensing bearing pin 5 is passed to controller by lead-in wire 4 signal, when chain or sprocket wheel have fault, sensing bearing pin 2 and suspension hook sensing bearing pin 5 stress balances change and jointly signal are defeated by controller by lead-in wire 4, when chain pull transfinites, sensing bearing pin 2 has limit for tonnage effect, avoid accident to occur.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, and the technology distortion that every technical scheme according to the present invention is made, within all falling into protection scope of the present invention.
