Embodiment Construction
[0046] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, and are not exhaustive of all the embodiments. And in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.
[0047] During the invention process, the inventor noticed that for the drilling and coring of railway tunnels, the length of a single drill pipe cannot meet the demand due to the long and narrow space of the mining roadway, that is, it is necessary to use extension rods to achieve deeper hole depth requirements. The existing method of connecting rods in construction is generally manual connecting rods, which is very inefficient, takes a long time, has low work...

The invention provides an automatic connecting rod mechanism of a drill jambo and the drill jambo. The automatic connecting rod mechanism comprises a rod connection assembly, a drill rod library and aswing rod feeding mechanism, wherein the rod connection assembly comprises a front-end bit retainer and a jackdrill bit shank, the front-end bit retainer is connected to a front-end support of a jackdrill and is matched with the bit shank to achieved rod connection. The drill rod library is connected to the front-end support of the jackdrill and located on the side face of a jackdrill boosting beam and used for storing a drill rod. The swing rod feeding mechanism is connected to the front-end support of the jackdrill and located between the front-end bit retainer and the bit shank and swingsbetween the drill rod library and the rod connection assembly to deliver the drill rod. The automatic connecting rod mechanism of the drill jambo can change the problems of low manual rod connection efficiency and poor safety and can greatly improve the rod connection efficiency and rod connection stability and reliability.
Description
technical field [0001] The invention belongs to the technical field of rock drilling construction equipment, and in particular relates to an automatic rod connecting mechanism of a rock drilling jumbo and a rock drilling jumbo. Background technique [0002] Rock drilling jumbo is a kind of construction machinery equipment used in tunnel excavation and underground engineering excavation. Its main construction method is drilling and blasting construction. The core device of its application is a rock drill. The drill rod is installed on the rock drill, and the rock is broken by the rotation and impact of the rock drill to achieve the drilling function. In some cases, such as drilling and coring of railway tunnels, the length of a single drill pipe cannot meet the demand due to the narrow and long space of the mine roadway, that is, it is necessary to use the extension rod to achieve a deeper hole depth. The existing construction connecting rod mode is generally a manual connec...
