Description

A hanging weighing system

technical field

The utility model relates to the field of lifting equipment weighing, in particular to a hoisting weighing system.

Background technique

Cranes, crawler cranes or cranes are commonly used lifting equipment. The structure of its hoisting and weighing system is: including a pulley block, two tension sensors, a hook, and a weighing processing transmission module. The upper ends of the two tension sensors are symmetrically installed on the pulley block bracket. The hook is hinged between the lower ends of the two tension sensors, and the weighing processing transmission module is mounted on one side of the tension sensor. This method has the following disadvantages: 1. The weighing measurement data comes from two sensors, and the data is inaccurate; 2. The sensor is installed on the hook, near the hoisting place, and the vibration of the load, especially the occasional impact, affects the performance of the sensor. is fatal.

Contents of the invention

The technical problem to be solved by the utility model is to provide a hoisting and weighing system for the deficiencies of the prior art.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a lifting weighing system, including a hook hinged on the pulley at the bottom of the lifting equipment; a steel wire rope is wound around the pulley of the lifting equipment above; the starting end of the wire rope is connected to one end of the tension sensor; the end of the wire rope is connected to the winch for installing the lifting equipment; the other end of the tension sensor is hinged to the lifting equipment; the tension sensor Electrically connected with the controller.

The tension sensor is electrically connected with the controller through electric wires; the electric wires are wound on an adjuster for adjusting the length and direction of the electric wires.

One end of the tension sensor is fixedly connected to the upper connecting frame; the upper connecting frame is hinged to the lifting equipment; the other end of the tension sensor is fixedly connected to the lower connecting frame; the lower connecting frame is fixedly connected to one end of the sleeve frame; The other end of the sleeve is installed at the starting end of the steel wire rope. It is convenient to replace the tension sensor according to the maximum lifting capacity of the lifting equipment.

The controller is connected with the button module and the display module.

The controller, key module and display module are all installed in the casing to protect the controller, key module and display module from external damage.

Compared with the prior art, the utility model has the beneficial effects as follows: the utility model is accurate, stable and reliable, and a single tension sensor can measure the weight of the material hung by the hook, and the weighing data comes entirely from one sensor, ensuring that the original data The accuracy of the tension sensor is input to the controller through the wire for processing, and it will be displayed on the display after processing. Furthermore, the tension sensor is connected to the beginning of the wire rope, not only away from the load of the hook, but also has a great buffering effect of the wire rope in the middle , When the load is subjected to vibration and sudden impact, ensure that the tension sensor is not damaged, thereby ensuring the reliability of the entire system. Furthermore, the data is transmitted through wires to ensure that it will not be affected by other radios, thereby ensuring the stability of the system. According to the maximum lifting capacity of the lifting equipment, it is very simple to change the size of the tension sensor and the connecting components, and can be widely used in various lifting equipment.
