Abstract

The invention provides a load loading device and a method. The device is used for a crane, the device comprises a pull ring, a loading oil cylinder, a tension sensor and a loading controller, the pull ring is used for connecting a steel wire rope of the crane, the tension sensor is connected to a position between the pull ring and the loading oil cylinder, and the loading controller is configured to adjust the oil pressure difference between a rod cavity and a rodless cavity of the loading oil cylinder according to a tension detection signal of the tension sensor. According to the load loading device, the loading oil cylinder, the tension sensor and the loading controller cooperate with one another so that the tension applied to the crane by the pull ring connected with the loading oil cylinder can be accurately controlled, the safety of a loading experiment of the crane is improved, and meanwhile, the accuracy and the efficiency of the experiment are further improved.

Description

technical field [0001] The invention belongs to the technical field of crane load detection, and in particular relates to a load loading device and method. Background technique [0002] The function of the truck crane is to hoist the load. In the inspection and testing of the crane, the load test is a very important part. According to the requirements of regular inspection regulations and supervisory inspection regulations promulgated by the State Administration of Quality Supervision, cranes need to undergo load tests, including no-load, rated load, dynamic load, and static load tests. Safety is the top priority during the operation of truck cranes. Its anti-tipping ability, that is, its hoisting stability performance, determines whether it can safely complete the hoisting task. As an important safety performance index, the hoisting stability of new products requires Carry out precise tests for dangerous working conditions to obtain accurate stability data of the product, ...
