Abstract

The invention relates to a telescopic propulsion structure, a thruster assembly, rock drilling equipment and a telescopic propulsion method, and belongs to the technical field of rock drilling equipment. According to the technical scheme, the telescopic propulsion structure comprises a bracket (100), a first guide frame (200), a second guide frame (400) and a drive mechanism connected between thefirst guide frame (200) and the second guide frame (400). The drive mechanism is used for driving the second guide frame (400) moving relative to the first guide frame (200), and both the first guideframe (200) and the second guide frame (400) slide along the bracket (100) in the axial direction. The telescopic propulsion structure, the thruster assembly, the rock drilling equipment and the telescopic propulsion method have the positive effects that the drilling depth is increased and the clearance problem caused by layer-by-layer superposition is solved and circumvented cleverly, and the overall positioning accuracy of the thruster assembly is not reduced in the slightest; and meanwhile, compared with other telescopic thrusters, the overall height of the thruster assembly is effectivelyreduced, and the operation of operators and the observation of a hole drilling position during operating are facilitated.

Description

technical field [0001] The invention relates to a telescopic propulsion structure, a thruster assembly, rock drilling equipment and a telescopic propulsion method, belonging to the technical field of rock drilling equipment. Background technique [0002] Rock drilling jumbo, also known as drilling jumbo, is a kind of rock drilling equipment used in tunnel and underground engineering construction by drilling and blasting method. After the rock drilling jumbo completes the blast hole drilling operation, it usually also needs to undertake the drilling operation of the bolt hole used for roadway support. In the drilling and blasting construction operation, in order to improve the tunneling efficiency, it is usually necessary to increase the footage in meters of a single shot. Therefore, when conditions permit, it is generally desired to increase the drilling depth of the rock drill on the rock drilling rig. In the prior art, a propeller assembly is provided on the rock drillin...
