Abstract
The utility model discloses a warning device of a hoisting clamp, which comprises a force straining sampling device, a signal processing device and an alarm device which are sequentially connected. The force straining sampling device is arranged on a force bearing part of the clamp for measuring clamping force and hoisting weight of the clamp, and the signal processing device is used for comparing the measured clamping force and hoisting weight with specified clamping force and specified hoisting weight. When the measured clamping force is lower than the specified clamping force or the measured hoisting weight is higher than the specified hoisting weight, the alarm device is started for alarming. The utility model further discloses the intelligent clamp for hoisting provided with the warning device. The warning device of the intelligent hoisting clamp can give out an alarm when clamping force of the clamp for hoisting on a hoisted object is insufficient or actual hoisting weight exceeds specified hoisting weight of the clamp, thereby guaranteeing that operating staff can safely and reliably use the clamp for hoisting, avoiding accident hidden hazard, and improving operation safety.
Description
Technical field
The utility model relates to a kind of and reuses intelligent clamp, particularly reuses intelligent clamp and has 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.
The utility model content
The technical problems to be solved in the utility model 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 utility model 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 utility model 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 utility model is: the utility model can be reported 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.
