[Abstract]:Aiming at the inconvenient angle adjustment of downhole hydraulic drilling rig, this paper investigates the function and structure of the anchor drill, the frame hydraulic drill, the full hydraulic tunnel drill and the crawler hydraulic drill, and emphatically analyzes the angle adjusting devices of the above four kinds of drilling machines. Based on the structural characteristics of the hydraulic tunnel drilling rig, the indexing mechanism is discussed and designed. After comparing the indexing functions of several traditional standard parts, the planetary wheel rotary device is selected as the indexing mechanism. The indexing mechanism is composed of planetary gear train and steering platform. The mathematical model of the indexing mechanism is established with the reference of ZDY2300S hydraulic drilling rig. The load of the planetary wheel rotating device is calculated. According to the design criterion of the tooth root bending fatigue strength, the sun wheel is designed. Dimensions of planetary gears and inner gears. After that, the steering gear matching the structure of the planetary gear train is designed. The steering gear consists of two parts: the connecting plate and the steering table. The connecting plate is the connecting part between the feeding device of the ZDY2300S drilling rig and the planetary wheel rotating device. The steering platform is the gravity bearing part of the connecting plate and the functional carrier. After the design of the indexing mechanism is completed, the shear-fork hydraulic lifting platform and the fixed parts are designed. Based on the minimum load of 2000kg, the dimensions of the hydraulic cylinder of the lifting platform are calculated, and the structural design of the hydraulic cylinder is completed. With reference to the existing fixing methods of the pedestal rig, the corresponding fixing parts are designed, including the transverse column, the indexing circular rail and the clamping joint. The linear statics analysis of the designed indexing mechanism, the shear fork lifting platform and the fixed parts, the modal analysis of the planetary gear train and the assembly of the frame, and the transient dynamic analysis of the meshing of the solar wheel and the planetary wheel are carried out. The whole displacement, equivalent stress and other cloud diagrams of the corresponding structure are obtained by finite element analysis. The strength, stiffness and stability of the structure are determined according to the analysis results to meet the design requirements. Finally, the ANSYS workbench response surface optimization module is used to optimize the size of the steering gear and the hydraulic lift platform, and the structure topology of the steering platform is optimized to realize the lightweight design.
