Cantilever crane translation structure with high translation precision

Abstract

The invention relates to a cantilever crane translation structure with high translation precision, which relates to the technical field of mechanical cantilever cranes. The cantilever crane translation structure comprises a drill boom seat, a drill boom front seat, a hydraulic rear arm assembly and a hydraulic front arm assembly, the drill boom seat and the drill boom front seat are mutually mounted in an inverted mode, the hydraulic rear arm assembly is arranged outside the drill boom seat, and the hydraulic front arm assembly is arranged outside the drill boom front seat and connected with the hydraulic rear arm assembly; and the hydraulic rear arm assembly and the hydraulic front arm assembly are arranged in a similar structure in a specific proportion. Translation is achieved through the structural size and hydraulic control, the structure is simple, and the weight of the structure is far lower than that of similar products in the market; meanwhile, operation is easy, four oil cylinders can be controlled at the same time only through a linked pilot handle; in addition, the translation precision is determined by the size of a structural part, and the situation that the translation precision is shifted due to the fact that the technical level of debugging personnel is good or bad is eradicated; and the size of the part does not shift along with the working environment, and the translation precision is high in reliability.

Description

technical field [0001] The invention belongs to the technical field of mechanical arms, and in particular relates to an arm translation structure with high translation precision. Background technique [0002] A drilling rig refers to a walking drilling machine that supports a rock drill for mechanized rock drilling. Used for drilling shallow and deep holes in surface mining and stripping, underground mining and roadway excavation, chamber excavation, railway, hydropower and other stonework projects; [0003] In order to achieve the highest blasting efficiency when excavating blastholes, it is required that all blastholes must be perpendicular to the excavation surface. Traditional boom structures for tunneling drilling rigs mainly use the following two methods to adjust the angle of the drill pipe: [0004] The first is manual adjustment, which is inefficient, time-consuming and labor-intensive, and the work intensity of personnel is high. [0005] The second is to achieve...

Problems solved by technology

[0004] One is manual adjustment, which is inefficient, time-consuming and labor-intensive, and requires high labor intensity

[0005] The second is to achieve angle maintenance through software control. This method needs to arrange sensors, calculation and adjustment modules, and the manufacturing and maintenance costs are high. Due to the harsh working environment of the tunneling drilling rig, the reliability of relying on the electronic system is low;
