Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are described in detail:

referring to fig. 1, the drill rod guide device for a jumbolter of the present invention includes a guide mounting seat 4, and an adjustable adjusting mounting seat 2 is locked and connected to the guide mounting seat 4; further referring to fig. 3, a plurality of sets of longitudinally extending strip-shaped holes are formed in the adjusting mounting base 2, and the adjusting mounting base 2 and the guiding mounting base 4 are connected in a locking manner through bolts and locking nuts penetrating through the strip-shaped holes. Through the arrangement, the guide support center and the rotation center of the drill rod of the anchor rod drilling machine can be arranged coaxially in the installation process.

As shown in fig. 2, a lifting installation seat 10 capable of moving longitudinally is slidably connected inside the guide installation seat 4, and a middle guide wheel frame 5 is fixedly connected to the upper part of the lifting installation seat 10; swing arms 6 hinged with the guide mounting seat 4 are arranged on two sides of the middle guide wheel frame 5, the two groups of swing arms 6 are symmetrically arranged relative to the central line of the middle guide wheel frame 5, and the middle parts of the two groups of swing arms 6 are hinged with the guide mounting seat 4 through pin shafts. The upper part of the middle guide wheel frame 5 and the upper parts of the two groups of swing arms 6 are respectively and rotatably connected with a guide wheel 7. When the lifting mounting base 10 moves upwards, the upper ends of the two groups of swing arms 6 are folded inwards, and when the lifting mounting base 10 moves downwards, the upper ends of the two groups of swing arms 6 are opened outwards.

Furthermore, two groups of swing guide grooves 13 symmetrically arranged about the central line of the middle guide wheel frame 5 are formed in the lifting mounting seat 10, and the two groups of swing guide grooves 13 are distributed in a splayed shape. The lower end portions of the two groups of swing arms 6 are connected with sliding mandrels 12 which penetrate through the corresponding swing guide grooves 13, and the sliding mandrels 12 are in sliding contact with the corresponding swing guide grooves 13.

As shown in fig. 2, a longitudinally extending lifting guide groove 8 is formed on an inner side wall of the guide mounting seat 4, a lifting slider 11 slidably connected to the lifting guide groove 8 is mounted on the lifting mounting seat 10, and the present embodiment further includes a driving cylinder 1 for driving the lifting mounting seat 10 to move longitudinally. When the piston rod of the driving oil cylinder 1 extends out, the three groups of guide wheels 7 are synchronously folded inwards, and when the piston rod of the driving oil cylinder 1 retracts, the three groups of guide wheels 7 are synchronously expanded outwards. Further, the lower end of the lifting mounting seat 10 is connected with a movable mounting part 9, a T-shaped groove is formed in the movable mounting part 9, a clamping part penetrating through the T-shaped groove is connected to the extending end of the driving oil cylinder 1, and therefore the extending end of the driving oil cylinder 1 is movably connected with the movable mounting part 9.
