Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, the automatic positioning device of the excavation rock drilling rig includes a hole supporter 8, a distance measuring sensor 11, a propulsion beam positioner 9, a lifting cylinder displacement sensor S1 and S2, a pitching cylinder displacement sensor S3 and S4, and a side cylinder displacement sensor Sensor S5. Hole supporter 8 is installed on the front end of the propelling beam and encloses the position of the drill bit. The ranging sensor 11 is installed under the opening supporter 8 and has anti-collision protection. Propelling beam positioner 9 is installed in the lower part of propelling beam front end. The displacement sensor is installed inside or outside the oil cylinder; wherein the lifting oil cylinder 6 and the pitch oil cylinder 4 are double oil cylinders, and the strokes of the two oil cylinders can be differen...

Abstract

The invention discloses a drilling automatic positioning device and method for a tunneling and drilling jumbo. The device comprises a drilling supporter, a distance measuring sensor, an advancing beam positioner, displacement sensors, an angle sensor, a laser alignment part, an interactive display terminal, a controller and a handle. The distance measuring sensor is used for determining a position relation among the tunneling and drilling jumbo, an advancing beam and an operation roadway face; the displacement sensors are respectively arranged on a near-slope oil cylinder, a telescopic oil cylinder, a pitch oil cylinder, a compensating cylinder and a lift cylinder; the angle sensor is arranged on a rotary oil cylinder; the interactive display terminal is used for the display of data and the selection and setting of a hole arrangement mode; the controller is used for receiving an instruction and driving a hydraulic valve, controlling strokes of oil cylinders, calculating the position and pose of the advancing beam by the measured data of the sensors, and finally determining the position of a drill; the handle is used for controlling the operation of the jumbo. According to the device and the method, drilling automatic positioning is realized according to the hole arrangement mode, the automation degree of the drilling jumbo is improved, the technical requirements on operators are reduced, the efficiency of tunnel operation is improved and the service lives of a drill pipe and the drill are prolonged.

Description

technical field [0001] The invention relates to the field of mechatronics, in particular to an automatic drilling positioning device and method for a rock drilling jumbo. Background technique [0002] Roadway rock drilling has experienced manual excavation, pneumatic tools, semi-automatic trolleys, and fully automated trolleys. Among them, the semi-automatic trolley is the best in terms of cost efficiency, but the efficiency of drilling positioning is low, which restricts the greater performance of the equipment. Therefore, the automatic positioning of drilling holes can be realized, especially the automatic positioning of drilling holes in the central area of ​​the roadway with high precision requirements, and the drilling work can be completed with manual assistance, which greatly improves efficiency, saves labor costs, and reduces the technical ability requirements for operators. In the case of a small increase in cost, the degree of automation is greatly improved, and s...
