Abstract

The invention discloses a positioning method and system for automatic point location of a drill jumbo. The method includes the steps that site survey is carried out on an operation site of the drill jumbo so as to obtain site conditions relevant to drill point location, and the site conditions comprise a drill boom front end position at the front end of a drill boom of the drill jumbo; the estimated position of a drill point to be drilled is matched with the site conditions so as to obtain the actual position of the drill point to be drilled on the operation site; and according to the actual position of the drill point to be drilled on the operation site and the drill boom front end position, positional deviation between the drill operation position of the drill boom front end and the drill operation position of the drill boom is obtained through calculation, so that the drill boom is positioned. Compared with the prior art, the relative positional deviation between the drill boom front end and the drill point to be drilled can be recognized more quickly and precisely by means of the method and system, and therefore the drill boom is guided for point location more quickly and precisely.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a positioning method and system for automatically finding a point of a rock drilling jumbo. Background technique [0002] Drill and blast is a commonly used method of excavating rock. The general process of the drill and blast method is to first open a hole in the rock, then fill the hole with explosives, and finally use the explosives to explode to excavate the rock. In the early days, the drill and blast method was carried out by artificial hands and hammering to drill holes to realize the opening of holes in the rock. With the advancement of technology, the method of manual drilling is gradually eliminated due to its shortcomings such as high working intensity and low efficiency. [0003] The rock drilling jumbo is a kind of rock drilling equipment that adopts the drilling and blasting method for tunnel and underground engineering. It is mainly composed of rock drill, drilli...
