Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and in particular to a multi-functional rock drilling rig. Background Technology

[0002] Existing rock drilling rigs have relatively limited functionality, often used only for drilling blast holes, exploratory holes, and pipe roof installations during tunnel construction, with high usage frequency. To improve construction efficiency, three-arm rock drilling rigs are commonly used, including a foundation-supporting mobile platform, three drilling arms, and a suspended platform arm mounted on the platform. The three drilling arms are designated as Arm 1, Arm 2, and Arm 3, spaced alternately on the left, center, and right, for tunnel drilling or pipe roof installation. The suspended platform arm is located next to Arm 2 for manual assistance. Each of the three drilling arms has a drilling module mounted on its front end via a bracket. Currently, rock drilling rigs cannot be used for anchor bolt installation; anchor bolt installation requires a dedicated integrated drilling-anchor-injection rig, the core component of which is the integrated drilling-anchor-injection module (such as...). Figure 1 As shown in the figure, the rotating telescopic boom 2 is mounted on the foundation-supporting mobile platform (not shown) via bracket 1. A first rotary reducer 5 and a second rotary reducer 6 are also installed between bracket 1 and rotating telescopic boom 2. The integrated drilling, anchoring, and grouting module includes a drill arm beam 3 and an anchor beam 4. Drill rods are installed on the drill arm beam 3, and anchor beam 4 is equipped with anchor rods. However, the anchor rod construction operation time is short and the operation frequency is low, resulting in low utilization rate and poor economic efficiency of the integrated drilling, anchoring, and grouting machine. In addition, the equipment needs to frequently enter and exit the working face, which affects the tunnel construction efficiency. Utility Model Content

[0003] The present invention aims to modify the existing three-arm rock drilling rig to perform excavation and drilling operations while also having drilling and anchoring functions, thereby achieving parallel operation of processes and improving construction efficiency, equipment utilization and economy.

[0004] To achieve the above objectives, this utility model proposes a multi-functional rock drilling rig, which is modified from a three-arm rock drilling rig. It includes a basic support mobile platform and three rock drilling arms installed on the basic support mobile platform. The three rock drilling arms are arranged sequentially on the left, middle and right as Arm 1, Arm 2 and Arm 3. The front ends of Arm 1 and Arm 3 are equipped with rock drilling modules via brackets. The basket arm and Arm 2 on the basic support mobile platform are removed, and a rotating telescopic arm with an integrated drilling and anchoring module is installed at the original installation position of Arm 2 on the basic support mobile platform. The front end of the rotating telescopic arm is equipped with the integrated drilling and anchoring module via brackets. The integrated drilling and anchoring module includes a drill arm beam and an anchor beam. A separate flipping unit is also installed between the drill arm beam and the bracket, which enables the drill arm beam to rotate around its own axis.

[0005] As a preferred embodiment of the above scheme, the flipping unit is driven by a hydraulic motor, and two flipping units are arranged at intervals between the front and rear of the drill arm beam to jointly drive the drill arm beam to rotate.

[0006] The beneficial effects of this utility model are as follows: By modifying an existing three-arm rock drilling rig, removing the basket arm and the second arm, and installing a rotating telescopic arm with an integrated drilling and anchoring module at the original installation position of the second arm, and installing a separate tilting unit between the drill arm beam and the bracket, the drill arm beam can rotate around its own axis. This solves the problems of the rock drilling rig's single function, low utilization rate of other supporting equipment, low economic efficiency, and the separate process occupied by anchor bolt construction, which affects tunnel construction efficiency. By multifunctionally modifying the rock drilling rig, the number of integrated drilling and anchoring machines that can be purchased can be reduced, saving procurement costs; it also enables parallel operations of tunnel anchor bolt construction and excavation drilling, improving tunnel construction efficiency.

[0011] like Figure 2 As shown in Figure 4, a multi-functional rock drilling rig is modified from a three-arm rock drilling rig. It includes a basic support platform 7 and three drilling arms mounted on the basic support platform 7. The three drilling arms are designated as Arm 1 (left), Arm 2 (middle), and Arm 3 (right), spaced at intervals. Drilling modules are mounted on the front ends of Arms 1 and 3 via brackets. The basic support platform is used to move the rock drilling rig and serves as a support platform for mounting the various arms. The above describes an existing three-arm rock drilling rig and will not be elaborated further.

[0012] The modified structure is as follows: the suspended basket arm and the second arm on the foundation support mobile platform 7 are removed, that is, only the first arm 8 and the third arm 9 are retained; and a rotating telescopic arm 2 with a drilling and anchoring integrated module is installed at the original installation position of the second arm on the foundation support mobile platform 7. That is, the drilling and anchoring integrated module 10, the bracket 11, and the rotating telescopic arm 2 are removed from the foundation support mobile platform of the drilling and anchoring integrated trolley and replaced on the foundation support mobile platform 7 of the three-arm rock drilling trolley.

[0013] The front end of the rotating telescopic boom 2 is equipped with a drilling, anchoring, and injection integrated module 10 via a bracket 2, combined with... Figure 1 As shown, the drill-anchor-grouting integrated module 10 includes a drill arm beam 3 and an anchor beam 4. Drill rods are installed on the drill arm beam 3, and anchor rods are installed on the anchor beam 4. The drill arm beam 3 and the anchor beam 4 are arranged side by side in parallel. It also includes a grouting assembly, which can carry out drill-anchor-grouting integrated construction. This part of the structure is exactly the same as the drill-anchor-grouting integrated module and installation structure on the original drill-anchor-grouting integrated trolley, and will not be described again here.

[0014] The drill arm beam 3, consisting of the drill-anchor-injection integrated module 10, bracket 11, and rotating telescopic arm 2, is a single unit that is installed on the three-arm rock drilling rig, replacing the original installation position of the second arm. The modification is that a separate tilting unit 12 is added between the drill arm beam 3 and the bracket 11, which enables the drill arm beam 3 to rotate around its own axis.

[0015] Ideally, the tilting unit 12 is driven by a hydraulic motor, utilizing the hydraulic system of the three-arm drilling rig to provide hydraulic power. Two tilting units 12 are spaced apart at the front and rear of the drill arm beam 3, working together to drive the drill arm beam to rotate. By using the hydraulic system on the three-arm drilling rig in conjunction with the configured hydraulic motor to drive the tilting unit 12 to tilt, and by having two tilting units 12 positioned at the front and rear to jointly drive the drill arm beam to rotate, stable and reliable rotation of the drill arm beam can be ensured.

[0016] like Figure 2 As shown, when anchor bolt construction is required, the central rotating telescopic arm 2 (originally the position of the second arm) performs radial anchor bolt construction in the tunnel, while the first arm 8 and the third arm 9 perform axial blasting. When anchor bolt construction is not required, the rotating telescopic arm 2 drives the drilling-anchoring-grouting integrated module 10 to rotate to a state parallel to the first arm 8 and the third arm 9, which can also be used for axial blasting.

[0017] However, because the drill arm beam 3 and anchor beam 4 of the integrated drilling-anchoring module 10 are arranged side by side in parallel, they occupy a relatively large space. When axial blasting is required on the edge of the arched rock surface, the drill rod on the drill arm beam 3 cannot approach the right edge of the rock surface because the anchor beam 4 occupies the right side space. Although the relative positions of the drill arm beam 3 and anchor beam 4 can be adjusted by the first rotary reducer 5 located under the bracket 1 of the integrated drilling-anchoring module 10, the adjusted drill rod position is not convenient for drilling and affects the accuracy of blasting. By adding a flipping unit 12, the drill arm beam 3 can rotate independently around its own axis at any position, thereby improving its accuracy and flexibility when drilling blasting holes.
