Embodiment Construction

[0010] During the test, the electric winch (1) is supplied with normal operating current and voltage, and the electric winch (1) works to pull the wire rope (8) to drive the drum assembly (4) to rotate. Since the roller assembly (4) and the magnetic powder brake (5) jointly generate load, and act on the torque sensor (3) installed at both ends of the roller assembly (4), the load roller (4) is measured by the torque sensor (3). torque. The signal obtained by the torque sensor (3) is collected by a PLC (programmable logic controller), and the sampled data is synchronously transmitted to a computer for calculation, archiving, and later data processing. The start and stop of the electric winch (1) under test is automatically controlled by the computer; the change of the tension of the electric winch (1) can be observed in real time through the computer, and a real-time tension characteristic curve and inspection report can be drawn as required.

Abstract

An intelligent device for testing the tensile force of an electric capstan in real time consists of a roller component, a magnetic powder brake, a reducer, and torque transducers, wherein the roller component, the magnetic powder brake and the reducer form an artificial load when the electric capstan works; torque reflected by the roller component is acquired by the torque transducers, and calculation and editing are carried out on data by self-developmental processing software; and both sides of the roller component are provided with one torque transducer respectively so as to eliminate the torque deviation generated when a steel cable is wound unevenly. The intelligent device for testing the tensile force of the electric capstan in real time has convenient and efficient operation; each set of testing device can greatly improve the production efficiency and the accuracy under the full load working condition; the intelligent device can automatically perform failure detection and diagnosis through a computer controlled detection process; and the intelligent device also designs measures such as effective linkage, isolation and anti-interference, so that the tested tensile force is not influenced by other external factors, and the whole test result has higher accuracy.

Description

Technical field [0001] The invention belongs to the field of electromechanical integration, relates to performance testing equipment of electromechanical products, and is mainly applied to the real-time detection of pulling force data of electric winches of various specifications. Background technique [0002] At present, there are many domestic enterprises producing vehicle (ship) electric winches and similar products, and more than 95% of the products are oriented to foreign markets such as Europe and the United States. However, there are quite a few export enterprises with mediocre product technology and relatively traditional and backward production methods, especially quality inspection methods. Due to the high requirements on the stability of the performance of such products in foreign countries, the production technology level and detection technology level of the products need to be improved urgently. At present, the widely used detection method is mainly manual ope...
