Abstract
The invention discloses a clamp attention device for hoisting, which comprises a shear strain sampling apparatus, a signal processing unit and a warning device which are connected in sequence, wherein the shear strain sampling apparatus is arranged on a bearing part of the clamp and is used for measuring the clamp force and the hoisting weight of the clamp; the signal process device is used for comparing the measured clamp force and the hoisting weight with a rated clamp force and the rated hoisting weight; when the measured clamp force is lower than the rated clamp force or the measured hoisting weight is higher than the rated hoisting weight, starting the warning device to warn. The invention also discloses an intelligent clamp for hoisting of the clamp attention device for hoisting. The attention device can warn when the clamp force of the clamp for hoisting to the hoisted objects is insufficient or the actual hoisting weight is larger than the rated hoisting weight, thereby ensuring that the operators can use the hoisting clamp safely and reliably, eradicating accident potentials, and improving the operation safety.
Description
Technical field
The present invention relates to a kind of and reuse intelligent clamp, particularly reuse intelligent clamp and reached and reuse the clamp alarming device for a kind of.
Background technology
Rise and to reuse clamp and be to use hoisting and hanging instrument widely, but because the weight of the thing of estimation lifting by rule of thumb just usually in actual use just might exceed its specified hoisting weight so lift by crane the actual weight of thing; In addition, in the handling process, the stressed of clamp is a variable, if stressed generation moment increase causes overload, just can cause serious damage to clamp, if just continue to use the potential safety hazard that causes easily in the operation, this also is the one of the main reasons that causes serious accident.
Summary of the invention
The technical problem to be solved in the present invention is to reuse clamp safety defect of insufficient in order to overcome of the prior art, provides a kind of rising of can reporting to the police when the use over range of clamp reuse intelligent clamp and reached and reuse the clamp alarming device.
The present invention solves above-mentioned technical matters by following technical proposals: reuse the clamp alarming device for a kind of, its characteristics are that it comprises a stress-strain sampling setup, a signal processor unit and a warning device that links to each other successively; This stress-strain sampling setup is located on the stressed member of this clamp, be used to measure the gripping power and the hoisting weight of this clamp, this signal processor unit is used for above-mentioned gripping power that records and hoisting weight are compared with a specified gripping power and a specified hoisting weight respectively, when the gripping power that records is lower than this specified gripping power or the hoisting weight that records when being higher than this specified hoisting weight, start this warning device and report to the police.
Wherein, the bridge circuit of this stress-strain sampling setup for constituting by strain-gauge, wherein this strain-gauge stick in this clamp be subjected to tensile elements or the part that is stressed on.
Wherein, this signal processor unit comprises an amplifying circuit and a voltage comparator.
Preferably, this signal processor unit and this warning device are with the wireless mode communication, and wherein this signal processor unit comprises a wireless launcher, and this warning device comprises a wireless receiver.
Another technical scheme of the present invention is: a kind ofly be provided with above-mentioned and reuse rising of clamp alarming device and reuse intelligent clamp.
Positive progressive effect of the present invention is: the present invention can report to the police when clamp surpasses its specified hoisting weight to the insufficient clamping force of lifting thing or actual hoisting weight rising to reuse, thereby can having used safely and reliably, the assurance operating personal reuses clamp, stop accident potential, improve operational security.
