Problems solved by technology

[0005] In view of this, the present invention aims to propose a drilling mechanism and a drilling machine equipped with the drilling mechanism, so as to solve the problem that the sliding frame is too long when the drilling mechanism is drilling, and it is not convenient for the sliding frame to stand up and drill holes and the sliding frame is too short. Cause problems such as insufficient drilling length

Embodiment Construction

[0055] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the description and sequence of specific structures in this section are only descriptions of specific embodiments, and should not be considered as limiting the protection scope of the present invention.

[0056] The embodiment of the present invention mainly improves the drilling mechanism from the following aspects, so that the drilling mechanism can adapt to various drilling requirements, such as in the case of limited roadway space, it can not only meet the requirements of deep hole drilling, but also meet the The sliding frame should not be too long, which will affect the requirements for topping the bolt holes; and increase the requirements of the drilling mechanism for drilling holes at var...

Abstract

The invention relates to a drilling mechanism and a drilling machine. The drilling mechanism includes a drilling arm and a bracket installed on the drilling arm. One end of the frame telescopic oil cylinder is fixed with a positioning top, and the other end is fixed in the slide frame; a drilling tool is fixed on the positioning top. By setting the telescopic oil cylinder in the carriage, after the telescopic oil cylinder of the carriage is extended, a long drilling tool can be installed on the positioning top at the end of the carriage to meet the requirements of deep hole drilling in engineering construction; moreover, the telescopic oil cylinder of the carriage can After being shortened, the length of the sliding frame can be greatly reduced, meeting the requirement of standing up the sliding frame to top the bolt hole in the limited space of the roadway, and expanding the drilling range and practicability.

Description

technical field [0001] The invention relates to drilling technology, in particular to a drilling mechanism and a drilling machine equipped with the drilling mechanism. Background technique [0002] At present, the drilling and blasting method is still the main method of rock roadway construction, and its construction process can be briefly summarized as: drilling - blasting - bolting - loading gangue. Drilling and bolting are usually accomplished by mechanized equipment such as hydraulic drilling rigs or drilling machines. However, there are many drilling mechanisms of these devices that cannot meet the operating conditions in narrow roadways. For example, when drilling a hole, it is usually desired to obtain the maximum drilling depth, which requires a long slide frame length, and when jacking a bolt, in order to allow the slide frame to stand up and hit the top anchor, the slide frame length is required to be short. [0003] As a result, the slide frame is too long and i...
