Problems solved by technology

During use, the steel wire rope of the hoist will vibrate and vibrate under force. At this time, the tension on the wire rope is much greater than the gravity of the lifted object, and the measured data will have a lot of sudden jump interference, and the data will be easily distorted after post-processing.
At present, in China, the tension of the wire rope is mainly monitored by measuring the oil pressure of the balance cylinder of the balance device and then converted into the weight of the heavy object. However, this method cannot eliminate the friction of the oil cylinder, and cannot accurately measure the tension of the wire rope. It also makes the safety of the wire rope The operation is restricted, which makes it difficult to guarantee the safe production of coal mine enterprises; this monitoring sensor can eliminate the above restrictions, the measuring force is directly the tension of the wire rope, and at the same time, it can also eliminate the vibration peak value, and reflect the load of the lifted object in real time and accurately, which is for the hoist. Safe operation provides strong technical support

Abstract

The invention discloses a tension monitoring sensor for eliminating a vibration peak value of elevator steel wire ropes. The tension monitoring sensor comprises an upper cover which is in movable fit with a telescopic pole of a hydraulic oil cylinder, a disk body which is in movable fit with a slide block, an oil cavity cylinder which is packaged by the upper cover and the disk body, wherein the upper cover is in threaded connection with the disk body and covers the disk body; the oil cavity cylinder is in threaded connection in the disk body; and a ring of copper rings used for sealing oil is arranged between the disk body and the oil cavity cylinder. The sensor is mounted between the slide block of a balancing and suspending device of a friction type elevator oil cylinder and the telescopic pole of the hydraulic cylinder; under the action of the tension of the steel wire ropes, the part, pasted with a strain gage, of the sensor generates elastic deformation to measure tension of each steel wire rope; and sum of tension of all steel wire ropes is total load hoisted by the elevator. The sensor is reasonable in structural design; influence of kick of stress caused by shaking, vibrating and the like of the steel wire ropes in an elevator working process can be eliminated, and tension of the steel wire ropes can be stably and accurately monitored in real time.

Description

technical field [0001] The invention relates to a tension monitoring sensor, in particular to a monitoring sensor for eliminating the tension vibration peak value of a steel wire rope of a friction hoist. Background technique [0002] The mine hoist is the "throat" of coal mine production, and its safe and efficient operation is directly related to the life safety of miners and the production efficiency of coal mines. The wire rope is an important part of the hoist. Its safety and reliability play a decisive role in the safety of the hoist. The wire rope directly bears the full weight of the lifting weight. Monitoring the tension on the wire rope can measure the tension in real time. The total load of heavy objects can be lifted, which can greatly improve the work efficiency of coal mine production and save time and effort. During use, the steel wire rope of the hoist will vibrate and vibrate under force. At this time, the tension on the wire rope is much greater than the g...
