Problems solved by technology
However, due to the complex structure of the track shoe, it is very difficult to accurately construct the transfer matrix, and the track shoe runs at different positions on the track, and its force-applying parts, force-bearing methods, and force-bearing characteristics are quite different, so the transfer matrix also varies with the track shoe. Depending on the position of the board, it is affected by the driving conditions of the equipment
The currently applied transfer matrices are difficult to accurately express the relationship between the measured strain and the required load, resulting in low load measurement accuracy

The invention discloses a track link. The track link comprises a track link base body (1) and a plurality of pin lugs (2) located on two sides of the track link base body (1). The track link further comprises connection devices (3), the pin lugs (2) are connected to the track link base body (1) through the connection devices (3), each connection device (3) comprises a sensing device (32), and each sensing device (32) can detect pulling force and pressure between the corresponding pin lug (2) and the track link base body (1). The invention further discloses a track load measuring device comprising the multiple track links and track type engineering machinery. The sensing devices (32) are arranged in the connection devices (3) connected with the track link base body (1) and the pin lugs (2), and therefore the pulling force and the pressure between the pin lugs (2) and the track link base body (1) can be directly detected, force of the pin lugs (2) and force of the track link base body (1) are added to obtain load between the track links, and accuracy and reliability of a measurement result are greatly improved.
Description
technical field [0001] The present invention relates to the field of crawler construction machinery, in particular to a crawler shoe and a crawler load measuring device with the crawler shoe, and also relates to a crawler construction machine with the crawler load measurement device. Background technique [0002] The crawler traveling mechanism is an important part of crawler machinery (such as crawler cranes, roadheaders and other modern hoisting and mining equipment), which plays the role of bearing the weight of the whole machine and ensuring the movement of the machine body. The load between the track shoes is the main driving force for the crawler. Under the action of the load between the track shoes, the track can be wound along the driving wheel and laid continuously on the ground, so as to meet the various driving needs of the equipment. Restricted by the working environment of crawler machinery, the working conditions of the crawler driving mechanism are harsh. It n...
