After the anchor bolt hole drilling is completed, the anchor bolt drilling rig is put into non-working state, and the upper end face of the top seat is separated from the coal mine roadway wall. The drill rod on the anchor bolt drilling rig is aligned with the next anchor bolt hole drilling point.

[0053] The technical effect of the above solution is that it enables operation using the rear space as the installation area.

[0102] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0103] A method for using a hydraulic anchor bolt hole repair drilling rig for coal mines based on a split-frame support, the steps of which are as follows: Place the single-plate lug of the rear vehicle body 2 into the lug part I12, and insert the pin 13 into the lug part I12, thereby connecting the rear vehicle body 2 with the front vehicle body 1. This causes the luffing telescopic cylinder 9, the telescopic cylinder 90, and the lifting telescopic cylinder part 914 to be in a retracted state. Through the top seat part 913, the anchor drill 92 is positioned at the front end corresponding to the rear vehicle body 2. By rotating the support 8, the anchor drill 92 is positioned at the rear end of the rear vehicle body 2. By rotating the cylinder 94, the anchor drill 92 is positioned in a longitudinal state. When the engine part 31 is in operation... When the vehicle body 11 is in a driving state, the transfer case 32 is in an operating state, causing drive shaft I 33 and drive shaft II 34 to rotate. When the vehicle body 11 is operated by the steering system, drive shaft I 33 drives the rubber wheel drive axle of the vehicle body 11 to move, and drive shaft II 34 drives the rubber wheel drive axle of the rear vehicle body 2 to move, thus putting the front vehicle body 1 and the rear vehicle body 2 into a driving state. When drive shaft I 33 and drive shaft II 34 are in a non-rotating state, the parking brake 35 is in an operating state, thus putting the front vehicle body 1 and the rear vehicle body 2 into a stopped state. When the hydraulic device 7 is in operation, it outputs variable flow rate high-pressure hydraulic fluid. The distance between the telescopic outriggers I 42 and II 43 is adjusted via the control valve on the hydraulic device 7 and the intermediate beam 41. When the telescopic outriggers I 42 and II 43 are in the extended state, the intermediate beam 41 is raised, thereby lifting the rear vehicle body 2 off the ground. The anchor drill 92 is omnidirectionally adjusted in the horizontal plane by the rotational movement of the rotating support 8. The swing angle of the anchor drill 92 in the horizontal plane is adjusted by the swing of the hinged strip at one end of the outer shell of the telescopic cylinder 90 on the ear seat II 62 and one end hinged strip of the luffing cylinder 9 on the ear seat III 63. The telescopic movement causes the inner end of the telescopic cylinder 90 to swing in the vertical plane, adjusting the swing angle of the anchor drilling rig 92 in the vertical plane. The rotation of the rotary cylinder 94 allows for omnidirectional angle adjustment of the anchor drilling rig 92 in the vertical plane. The telescopic cylinder 90 adjusts the lateral position of the anchor drilling rig 92, thereby adjusting its working position. The movement of the moving seat 912 causes the lifting telescopic cylinder 914 to move laterally, adjusting the lateral position of the top seat 913. The telescopic movement of the lifting telescopic cylinder 914 causes the top seat 913 to rise and fall, adjusting its height. When a hydraulic anchor bolt drilling rig for coal mines is needed, the front body 1 and the rear body 2 are in a driving state. The rear body 2 is placed in the anchor hole operation area of ​​the roadway, and the front body 1 and the rear body 2 are stopped. The rear body 2 is lifted off the ground. The working position of the anchor bolt drilling rig 92 is adjusted so that the drill rod on the anchor bolt drilling rig 92 is aligned with the anchor bolt hole drilling point. The height of the top seat 913 is adjusted so that the upper end face of the top seat 913 acts on the coal mine roadway wall, putting the anchor bolt drilling rig 92 into working state to perform anchor bolt hole drilling. After the anchor bolt hole drilling is completed, the anchor bolt drilling rig 92 is put into non-working state, the upper end face of the top seat 913 is separated from the coal mine roadway wall, and the drill rod on the anchor bolt drilling rig 92 is aligned with the next anchor bolt hole drilling point.

[0104] In verifying this invention, the inventors abandoned the existing technical feature of using a tracked chassis with an integral frame to support the anchor drilling rig. Instead, they first proposed a technical feature of using an articulated motor vehicle body for workstation transfer in the anchor drilling site. This resulted in the first unexpected technical effect: enabling rear-mounted spatial connection and installation of the anchor drilling rig 92, optimizing the connection and installation of other components of the anchor drilling rig 92, and improving the usability of the hydraulic anchor hole repair drilling rig device for coal mines. The second unexpected technical effect was achieved: using the front vehicle body 1, rear vehicle body 2, and power unit 3 as an articulated motor vehicle body improved performance in coal mines. The improved movement performance in the tunnel resulted in a third unexpected technical effect: it enabled the adjustment of the drilling posture of the anchor bolt drill 92 via the support frame 6, rotating support 8, amplitude-changing telescopic cylinder 9, telescopic cylinder 90, and rotating cylinder 94, thus improving the drilling posture accuracy of the anchor bolt drill 92 and increasing the efficiency of the hydraulic anchor bolt hole repair drilling rig for coal mines. A fourth unexpected technical effect was achieved: it enabled the delivery of high-pressure hydraulic fluid via the hydraulic device 7, improving the reliability of the hydraulic anchor bolt hole repair drilling rig for coal mines. A fifth unexpected technical effect was achieved: it enabled support for the operator via the pedal 93, improving the efficiency of anchor bolt hole repair operations. As a result, the sixth unexpected technical effect was achieved: the rear vehicle body 2 was fixedly supported by the front support leg 4 and the rear support leg 5, improving the stability of the rear vehicle body 2. The seventh unexpected technical effect was achieved: the anchor bolt drill 92 was fixedly supported by the lifting assembly 91, improving the positional accuracy of the anchor bolt holes in the anchor bolt drill 92. The eighth unexpected technical effect was achieved: the anchor bolt drill 92 was no longer always supported by a tracked chassis with an integral frame, eliminating the impact of the tracked chassis on the coal mine roadway environment. The ninth unexpected technical effect was achieved: the articulated vehicle body was introduced into the hydraulic anchor bolt holes used in coal mines. The application of this technology in the field of repair drilling rig equipment has achieved a tenth unexpected technical effect, resulting in a favorable working environment within coal mine roadways: It enables the use of the rear safety space of the articulated vehicle body for the installation of the anchor drilling rig 92, improving the transport performance of the anchor drilling rig 92 in coal mine roadways. It also enables rapid positioning of anchor holes requiring repair, making it particularly suitable for repairing anchor holes in coal mine roadways. An eleventh unexpected technical effect has been achieved: It enables variable-pressure high-pressure liquid delivery via hydraulic devices 7, meeting the intelligent control requirements of the hydraulic anchor hole repair drilling rig equipment for coal mines and satisfying the needs of coal mine roadways in different geological conditions.
