An adjustable car body, a center-of-gravity rock breaker and a rock breaking method

Abstract

The invention provides an adjustable type vehicle body, a center-of-gravity type rock breaking machine and a rock breaking method, and belongs to the field of mechanical rock breaking in the field of engineering machinery, which mainly solves the problems of failure to fully use self weight to enhance lower shearing force of mechanical working and loss of unnecessary energy in the existing rock breaking machine. The adjustable type vehicle body, the center-of-gravity type rock breaking machine and the rock breaking method are mainly applied to the construction engineering of rocks on medium-solid and solider rock strata. The adjustable type vehicle body is provided with a hollow part which penetrates through the adjustable type vehicle body from top to bottom, and comprises a power part, a hydraulic part, a control part, a walking mechanism and an adjusting assembly, wherein the adjusting assembly is used for adjusting the width of the adjustable type vehicle body. The center-of-gravity type rock breaking machine comprises the adjustable type vehicle body and a rock arm, wherein the rock arm penetrates through the hollow part to break rock. The adjustable type vehicle body has the advantages that rock can be broken by fully utilizing the weight of the whole machine in the working process, the vehicle body is stable, and the energy consumption is low; the size of the vehicle body is adjusted according to the actual conditions of an operation site, the application range is wide, and the transportation is convenient.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an adjustable vehicle body, a center-of-gravity rock breaker and a rock breaking method. Background technique [0002] Rock crushing is a process of separating part of the rock mass from the parent body and breaking it into rock blocks during mining operations. There are mainly four types of explosive crushing, mechanical crushing, water jet crushing and thermal crushing in the prior art. Among them, mechanical crushing is widely used because of its advantages of high safety and good crushing effect. At present, the main method of mechanical crushing is to use ordinary excavators to carry rock-breaking tools (hydraulic breaker, high-frequency breaker, ripper, rock arm, etc.), rock crackers, bulldozers, etc. for rock-breaking operations. [0003] Rippers are generally used for rock breaking operations in relatively strong and moderately strong rock formations, such as sandy s...

AI Technical Summary

Problems solved by technology

[0003] Rippers are generally used for rock breaking operations in relatively strong and moderately strong rock formations, such as sandy shale, general sandstone, shale sandstone, unsteady limestone, soft gravel, dense marl, and other rock formations. In the actual rock-breaking process, the rock-breaking part of the above device cannot make full use of the weight of the whole machine due to its own working principle, resulting in a large amount of unnecessary energy loss, which eventually leads to insufficient cutting force during operation, resulting in rock-breaking work. High consumption, slow speed, low efficiency of rock breaking construction
