Problems solved by technology
[0003] At present, the road drilling rig is a common engineering equipment for drilling deep holes in tunnel construction. There are many kinds of road drilling rigs, such as rock drilling rigs, bolting rigs, mining rigs, etc. The existing road drilling rigs are used in the daily construction process Among them, frequent labor is required to install or disassemble the drill pipes used for drilling, the degree of automation is low, the replacement efficiency of drill pipes is low, the labor intensity of workers is high, and the personal safety of workers cannot be guaranteed, which is not conducive to safe construction. Therefore, it is particularly necessary to design an automatic rod-changing device that can overcome the above-mentioned problems

The invention relates to the field of tunnelling drill carriage assistance mechanisms, in particular to an automatic rod changing device for a tunnelling drill carriage. The automatic rod changing device comprises a connecting seat, a drill rod warehouse, a main swinging mechanism, a secondary swinging mechanism, clamping bar oil cylinders and clamping bar arms, the drill rod warehouse is fixedlydisposed on the side of a propulsion beam of the tunnelling drill carriage through the connecting seat; the main swinging mechanism is disposed in parallel on the lower part of the drill rod library,and the secondary swinging mechanism is fixedly disposed on the main swinging mechanism; the clamping bar arms are detachably disposed at the two ends of the secondary swinging mechanism, the clampingbar oil cylinders are fixedly disposed on one sides of the clamping bar arms, and the clamping bar oil cylinders cooperate with the clamping bar arms to tighten a drill rod after extending out; and the clamping bar oil cylinders are externally connected with hydraulic driving equipment. The automatic rod changing device for the tunnelling drill carriage can automatically complete the operation ofreplacing the drill rod when the tunnelling drill carriage drills medium length holes, the manual rod changing is avoided, the rod changing efficiency is greatly improved, so that the working time ofthe tunnelling drill carriage is significantly shortened, and the construction efficiency is improved.
Description
technical field [0001] The invention relates to the field of an auxiliary mechanism for a drilling rig, in particular to an automatic rod changing device for a drilling rig. Background technique [0002] In the process of tunnel excavation construction and mining construction, drilling deep holes is a very practical means of advanced geological prediction of tunnels, trying to grasp the structure, nature and state of rock and soil ahead, as well as the occurrence of groundwater and gas before construction Geological information such as ground stress and ground stress will provide guidance for further excavation construction, so as to avoid geological disasters such as water gushing, gas outburst, rockburst, and large deformation during the construction process to ensure the safety and smooth progress of construction. [0003] At present, the road drilling rig is a common engineering equipment for drilling deep holes in tunnel construction. There are many kinds of road drilli...
