Propelling Beam Positive Follow-up Mechanism of a Rock Drilling Rig

Abstract

The invention discloses a propelling beam normal position servo mechanism of a drill jumbo. The propelling beam normal position servo mechanism comprises a main arm seat, a main arm, a connecting rod, a sliding seat, a propelling beam and a main arm oil cylinder. The main arm seat is installed at the front end of a rack of the drill jumbo, one end of the main arm is hinged to the main arm seat, the other end of the main arm is hinged to the sliding seat, the main arm oil cylinder is hinged between the main arm and the main arm seat, one end of the connecting rod is hinged to the main arm seat, the other end of the connecting rod is hinged to the sliding seat, the propelling beam is installed on the sliding seat, and a parallelogram mechanism is formed by the main arm seat, the main arm, the sliding seat and the connecting rod. By the adoption of the propelling beam normal position servo mechanism of the drill jumbo, it is guaranteed that the propelling beam cannot generate angle change relative to the main arm seat in the moving process, drilling and positioning time is saved, and the drilling and positioning speed is increased.

Description

[0001] Technical field: [0002] The invention relates to the technical field of rock drilling equipment, in particular to a forward beam follow-up mechanism of a rock drilling jumbo. [0003] Background technique: [0004] In recent years, the market's demand for construction machinery, especially various drilling equipment, has been increasing. The rock drill is a tool used for rock drilling. At present, most of the excavation of tunnels still uses traditional manual rock drills. Drilling operations make the progress of the project slow, the construction period is long, the cost is high, the safety hazard is prominent, and a lot of manpower, material resources, and financial resources are lost. With the development of science and technology, people have developed rock drilling rigs, which are used in tunnels and tunnels. It is a kind of rock drilling equipment that adopts drilling and blasting method in underground engineering. [0005] However, at present, the propulsion be...

[0004] In recent years, the market's demand for construction machinery, especially various drilling equipment, has been increasing. The rock drill is a tool used for rock drilling. At present, for tunnel excavation, most of them still use traditional manual rock drills. Drilling operations make the progress of the project slow, the construction period is long, the cost is high, the safety hazard is prominent, and a lot of manpower, material resources, and financial resources are lost. With the development of science and technology, people have developed rock drilling rigs, which are used in tunnels and A kind of rock drilling equipment that adopts drilling and blasting method in underground engineering

[0005] However, at present, the propulsion beam of the rock drilling rig cannot maintain an angle change relative to the main boom seat during the movement process, and the positioning speed is slow. In view of this, the applicant studies and improves the existing propulsion beam follower mechanism to ensure The angle of the propulsion beam does not change relative to the main boom seat during the movement process, which saves drilling positioning time and improves drilling positioning speed
