Movement；Under the driving of propelling cylinder 300, the second leading truck 400 retracts backward, and pricker operation is moved back in realization.
The setting of switch 820 afterwards realizes the second leading truck 400 with rock drill 600 and is moving back the linkage in pricker operation process
Movement, the automatic of second leading truck 400 retracts backward after ensure that the movement in place of rock drill 600, to improve the present embodiment
Flexible propeller assembly moves back the high efficiency and fluency of pricker operation process.
Preferably, in the present embodiment, the rear end of the second leading truck 400 is arranged in rear switch 820.
It should be noted that preceding switch 810 and rear switch 820 can be the shapes such as pilot operated valve device or solenoid valve in the present embodiment
Formula, also, preceding switch 810 and rear switch 820 can be the triggering form of contact shown in figure, can also be non-contact triggering
Form, as long as can realize the second leading truck 400 respectively by this set form of preceding switch 810 and rear switch 820
Linkage action in operation process and the second leading truck 400 is being promoted to move back pricker operation with rock drill 600 with rock drill 600
Linkage action in the process.
In the present embodiment, the first earrings can also be fixedly installed on bracket, can also be fixedly installed on the first leading truck
Two earrings.Such setting realizes the installation of 510 oil feed line of propelling cylinder 300, compensating cylinder 900 and feed cylinder,
The situation for causing interference to each moving component due to pipeline is at random is avoided to a certain extent, be ensure that the present embodiment is flexible and is promoted
The functional reliability of device assembly.
The groundwork process of the flexible propeller assembly are as follows: firstly, the jib lubbing mechanism using rock drilling equipment stretches this
Propeller assembly is placed in operating position；Then, the first leading truck 200 is driven back and forth to move on bracket 100 using compensating cylinder 900
It is dynamic, and positioned using the fixing seat 210 of the first leading truck 200.
It promotes in operation process, the rod chamber oil inlet of propelling cylinder 300, so that the piston rod of propelling cylinder 300 is with respect to it
Cylinder barrel retracts, so that the second leading truck 400 be driven to travel forward；When the preceding switch 810 and fixing seat on the second leading truck 400
When 210 contact, preceding switch 810 is triggered, and control signal is exported to feed cylinder 510, controls feed cylinder 510 and acts,
To realize the driving to rock drill 600；During rock drill 600 is fed forward along upper layer sliding rail 410, drill steel 700 begins
The guiding movement in pilot hole 211 eventually, when rock drill 600 is fed to forward the front end of the second leading truck 400, propulsion terminates.
It moves back in pricker operation process, the rod chamber oil inlet of feed cylinder 510, so that the piston rod of feed cylinder 510 is with respect to it
Cylinder barrel retracts, so that rock drill 600 be driven to move backward along upper layer sliding rail 410；When rear wheel supporting plate 530 and the second leading truck
When the rear switch 820 of 400 rear ends contacts, rear switch 820 is triggered, and control signal is exported to propelling cylinder 300, makes to promote
The rodless cavity oil inlet of oil cylinder 300, so that its piston rod is stretched out with respect to cylinder barrel, so that the second leading truck 400 opposite first be driven to lead
It is moved backward to frame 200, moving back pricker terminates.
In addition, the present embodiment additionally provides a kind of rock drilling equipment, specifically, the rock drilling equipment include rock drilling equipment ontology and
Above-mentioned flexible propeller assembly, wherein flexible propeller assembly is installed on rock drilling equipment ontology.
By the way that above-mentioned flexible propeller assembly is arranged in rock drilling equipment, correspondingly, which has above-mentioned flexible
The institute of propeller assembly is advantageous, and this is no longer going to repeat them.
