Embodiment Construction
[0014] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0015] Such as figure 1 As shown, the lifting clamp warning device of the present invention includes a force-strain sampling device 1, a signal processing device 2 and an alarm device 3 connected in sequence, and figure 2 What is shown is a schematic diagram of a lifting smart clamp equipped with the lifting clamp warning device. The force-strain sampling device 1 is set on the force-bearing part of the clamp, wherein the force-bearing part can be a pressure part or a tension part, such as a connecting rod, and certain protective measures should be taken to prevent the Accidental detachment of force-strain sampling device 1. The force-strain sampling device 1 is used to measure the clamping force and the actual lifting weight of the clamp in real time, and in order to realize the forc...

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 [0001] The invention relates to an intelligent clamp for lifting, in particular to an intelligent clamp for lifting and a warning device for the clamp for lifting. Background technique [0002] Lifting clamps are widely used lifting tools, but because the weight of the lifting object is usually estimated based on experience in actual use, the actual weight of the lifting object may exceed its rated lifting weight; During the transportation process, the force of the clamp is a variable. If the force increases instantaneously and causes overload, it will cause serious damage to the clamp. If it continues to be used, it will easily cause safety hazards in operation, which is also a major safety hazard. One of the main causes of accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect of insufficient safety of the lifting tongs in the prior art, and to provide a kind of intelligent lift...
