[0035] The specific implementation process of this utility model will be described below through several embodiments.

[0036] Example 1

[0037] See Figures 1 to 3 This embodiment discloses a specific implementation of a single-arm drilling rig based on a telescopic chassis.

[0038] See Figures 1 to 3 A single-arm drilling rig based on a telescopic chassis includes a telescopic chassis 1 and a single-arm anchor bolt assembly 2 and a shovel plate assembly 3 disposed at the front end of the telescopic chassis 1. The telescopic chassis 1 includes a chassis 11, a first track 12, a first telescopic cylinder 13, a second telescopic cylinder 14, and a second track 15. A first guide post 111 and a second guide post 112 are disposed between the chassis 11 and the first track 12, and a third guide post 113 and a fourth guide post 114 are disposed between the chassis 11 and the second track 15. The first telescopic cylinder 13 drives the first track 12 to extend and retract along the first guide post 111 and the second guide post 112 with the chassis 11 as the fulcrum. The second telescopic cylinder 14 drives the first track 12 to extend and retract along the first guide post 111 and the second guide post 112 with the chassis 11 as the fulcrum. The chassis 11 serves as a fulcrum, driving the second track 15 to extend and retract along the third guide post 113 and the fourth guide post 114. A slewing assembly 4 is installed above the chassis 11, driving the single-arm anchor bolt assembly 2 to rotate left and right. The shovel assembly 3 includes a shovel 31 and a first pitch cylinder 32 and a second pitch cylinder 33 disposed on both sides of the shovel 31. The first pitch cylinder 32 drives one side of the shovel 21 to pitch with the chassis 11 as a fulcrum, and the second pitch cylinder 33 drives the other side of the shovel 31 to pitch with the chassis 11 as a fulcrum. The shovel 31 not only serves to clear coal piles in the roadway but also stabilizes the vehicle when in contact with the ground.

[0039] Specifically, the telescopic chassis 1 in this embodiment has a width range of 0.9m-1.3m, adapting to narrow tunnels of different widths. When the first telescopic cylinder 13 and the second telescopic cylinder 14 are in the retracted state, the width of the telescopic chassis 1 is 0.9m. When the first telescopic cylinder 13 and the second telescopic cylinder 14 are in the fully extended state, the width of the telescopic chassis 1 is 1.3m, enabling the telescopic chassis 1 to pass through tunnels slightly wider than 0.9m. During anchoring, the contact area between the chassis and the ground can be increased by increasing the chassis width, thus making the vehicle body more stable. In this embodiment, anchoring is performed using a single-arm anchor bolt assembly 2. Through the rotating assembly 4, the single-arm anchor bolt assembly 2 can be brought close to the left or right side of the tunnel, or close to the left or right top of the tunnel, which is highly flexible and adaptable.

[0040] See Figures 1 to 2 A stop block 5 is provided in front of the rotary assembly 4 and is mounted on the chassis 11. A first stop plate 41 and a second stop plate 42 are respectively provided on both sides of the rotary assembly 4. The first stop plate 41 and the stop block 5 cooperate to form the first swing limit of the single-arm anchor bolt assembly 2. The swing angle of the first swing limit is -45°. The second stop plate 42 and the stop block 5 cooperate to form the second swing limit of the single-arm anchor bolt assembly 2. The swing angle of the second swing limit is 45°. Through the first swing limit and the second swing limit, the single-arm anchor bolt assembly 2 is prevented from swinging too much and hitting the sidewall of the roadway.

[0041] See Figures 1 to 2The working principle of the single-arm anchor bolt assembly 2 is as follows: The single-arm anchor bolt assembly 2 includes a base 21 installed on the rotary assembly 4, and also includes a telescopic boom 22, a pitch cylinder 23, a pedal assembly 24, a first rotating assembly 25, a second rotating assembly 26, and a drill arm 27; the telescopic boom 22 is hinged to the top of the base 21, and the pitch cylinder 23 drives the telescopic boom 22 to pitch with the middle of the base 21 as the fulcrum, and the telescopic boom 22 has a forward and backward telescopic function; the pedal assembly 24 includes a pedal 241, a leveling support 242, and a leveling cylinder 243, the leveling support 242 is hinged to the telescopic boom 22, the leveling cylinder 243 drives the leveling support 242 to pitch, the pedal 241 is installed on the leveling support 242, and when the telescopic boom 22 is in a pitching action, the pedal 241 can be kept in a horizontal position by the driving of the leveling cylinder 243. To facilitate standing operation, an operating box 244 is installed on the leveling support 242, allowing the operator to control the movement of the drill arm 27. The first rotating component 25 drives the second rotating component 26 to rotate, and the second rotating component 26 drives the drill arm 27 to swing. The rotation angle of the first rotating component 25 is 0°-270°, and the rotation angle of the second rotating component 26 is ±90°. The second rotating component 26 drives the drill arm 27 to switch between the left and right sides of the tunnel, and the first rotating component 25 drives the drill arm to switch between the tunnel side and the tunnel top. Through the cooperation of the first rotating component 25 and the second rotating component 26, full-section anchoring of the tunnel is achieved. When the single-arm anchor bolt assembly 2 needs to be in a retracted state, the first rotating component 25 and the second rotating component 26 cooperate to drive the drill arm 27 in a downward position to save space.

[0042] See Figures 1 to 2Given the narrowness of the chassis 11 in this embodiment, a top support assembly 6 is installed behind the slewing assembly 4 to maintain vehicle stability during anchoring operations. The top support assembly 6 is located in the middle of the chassis 11 and includes a first outer cylinder 61, a first-stage lifting cylinder (located inside the first outer cylinder 61), a second outer cylinder 62, a second-stage lifting cylinder (located inside the second outer cylinder 62), and a swing cylinder 63. The second outer cylinder 62 is hinged to the end of the telescopic rod of the first-stage lifting cylinder. The first-stage lifting cylinder drives the second outer cylinder 62 to rise and fall; the second-stage lifting cylinder drives the outrigger 64 to rise and fall. Through these two stages of lifting, the outrigger 64 can be driven to abut against the top of the tunnel to stabilize the vehicle. The swing cylinder 63 drives the second outer cylinder 62 to swing. When the top support assembly 6 needs to be in position... In the retracted state, both the first-stage and second-stage lifting cylinders are in the retracted state, and the swing cylinder 63 is in the flat position to reduce the overall size of the vehicle in the retracted state, making it easier to pass through narrow alleys. To further stabilize the vehicle body, a ground support leg 7 is provided at the rear of the telescopic chassis 1. A lifting cylinder is installed inside the ground support leg 7, and a lateral movement cylinder 71 is also provided at the top of the ground support leg 7. The lateral movement cylinder 71 can drive the ground support leg 7 to move laterally to increase its support range. The width between the two ground support legs 7 is 0.9m-1.7m, providing a large vehicle stabilization range. The lifting cylinder can drive the ground support leg 7 to touch or leave the ground. During anchoring operations, the support leg 64 touches the top of the alley, and the ground support leg 7 touches the ground, stabilizing the vehicle body. To enrich the functionality of this embodiment, a cable winding bracket 8 is also provided at the rear of the telescopic chassis 1.
