Problems solved by technology

[0003] Especially when the loader is full of materials, when constructing in small-scale sites such as hills and basins, due to the uneven road surface and large climbing angle, it is easy to lose balance, resulting in failure to construct or roll over
The existing solution is to place counterweights on the frame, and move the center of the vehicle back and forth or left and right by moving the counterweights. However, due to the fixed weight of each counterweight, it cannot meet the road requirements of various complex working conditions. When the counterweight is adjusted, the impact and noise are relatively large, which interferes with driving stability

Embodiment

[0030] Embodiment: When using the loader, connect the power supply of each sensor and chip in the fluid counterweight system 2 and the counterweight electronic control system 3, and the output terminals of the force sensor 33 and the slope sensor 32 are all electrically connected with the integrated drive chip 34 , the force sensor 33 is used to measure the weight of the load in the bucket 111, and transmits the load information of the bucket 111 to the integrated driver chip 34, as in Figure 4 The load of the internal measuring bucket 111 is m5g, and the slope sensor 32 is installed in the central channel at the bottom of the cockpit of the loader body 1. During installation, its direction must be consistent with the positive direction of the vehicle coordinates, and it is used to measure the gap between the slope surface and the horizontal surface. angle, as in Figure 4 The internally measured front and rear inclination angle is α, in Figure 5 The left and right inclinatio...

Abstract

The invention discloses a gravity center adjustable loading machine applied to the complex working condition. The gravity center adjustable loading machine comprises a loading machine body, fluid balancing systems and a balancing electronic control system. The fluid balancing systems are arranged on the left side, the right side and the interior of the loading machine body. The fluid balancing systems are electrically connected with the balancing electronic control systems. A bucket assembly is arranged on the front portion of the loading machine body. Each fluid balancing system comprises a first water tank, a second water tank, a third water tank and a fourth water tank, wherein the first water tank is installed on the right front side of the loading machine body, the second water tank is installed on the left front side of the loading machine body, the third water tank is installed on the right rear side of the loading machine body, and the fourth water tank is installed on the leftrear side of the loading machine body. Each fluid balancing system further comprises a first reversing valve and a second reversing valve, wherein the first reversing valve and the second reversing valve are two-position four-way type electromagnetic reversing valves. The gravity center adjustable loading machine has the characteristics of being stable in traveling and adapting to the complex working condition.

Description

technical field [0001] The invention relates to the technical field of loaders, in particular to a loader with an adjustable center of gravity applied in complex working conditions. Background technique [0002] Loader is a kind of earthwork construction machine widely used in highway, railway, construction and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand and lime, and can also be used for light shoveling of ore and hard soil. Operation. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. [0003] Especially when the loader is full of materials, when working on small-scale sites such as hills and basins, due to uneven road surfaces and large climbing angles, it is easy to lose balance, resulting in inability to work or rolling over. The existing solution is to place counterweights on the frame, and move the center of the vehicle...
