[0002] With the rapid growth of my country's national economy, the accelerated process of industrialization and mechanization of coal mines, the urgent demand for coal mine production safety, and the fact that coal resources remain at a dominant low level of energy demand for a long time, coal mines are in urgent need of transforming the original manual anchoring operation method into a mechanized anchoring operation method.

[0003] There are many types of anchor drilling vehicles for coal mines on the market. Since the diameter of the anchor hole is small and the depth is large, the existing anchor drilling vehicles use a drilling rig to drill the anchor hole on the tunnel wall. However, for areas with harder rocks on the tunnel wall, the efficiency of drilling the anchor hole with a drilling rig is low, which affects the progress of the anchoring operation. Summary of the invention

The inner diameter of the reference hole is larger than the inner diameter of the reference anchor hole, so that a thicker drill rod can be used for drilling, so that the drill rod can withstand the impact force of impact drilling and avoid drill rod breakage. A forming hole is drilled at the bottom of the reference hole, so that the depth of the forming hole is shallower than the bottom of the reference hole, making drilling easier. The diameter of the forming hole is the same as the inner diameter of the reference anchor hole, and the depth of the forming hole relative to the tunnel wall is the same as the depth of the reference anchor hole, so that the anchor hole formed by the reference hole and the forming hole can perform normal anchoring operations.

DETAILED DESCRIPTION

[0063] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0064] Please also read Figures 1 to 3 The anchor hole construction method provided by the embodiment of the present invention is now described. An anchor hole construction method includes:

[0065] A reference hole 7 is drilled on the tunnel wall by percussion rock drilling, wherein the inner diameter of the reference hole 7 is larger than the inner diameter of the reference anchor hole, and the depth of the reference hole 7 is smaller than the depth of the reference anchor hole;

[0066] A forming hole 8 is drilled at the bottom of the reference hole 7, the diameter of the forming hole 8 is the same as the inner diameter of the reference anchor hole, and the depth of the forming hole 8 relative to the tunnel wall is the same as the depth of the reference anchor hole;

[0067] The reference hole 7 and the forming hole 8 are connected to form an anchor hole.

[0068] Compared with the prior art, the anchor hole construction method of the embodiment of the present invention uses impact drilling to drill a reference hole 7 on the tunnel wall, which can quickly drill the reference hole 7 in the harder area on the tunnel wall, thereby improving the drilling efficiency. The inner diameter of the reference hole 7 is larger than the inner diameter of the reference anchor hole, so that a thicker drill rod can be used for drilling, so that the drill rod can withstand the impact force of impact drilling and avoid the breakage of the drill rod. The forming hole 8 is drilled at the bottom of the reference hole 7, so that the depth of the forming hole 8 relative to the bottom of the reference hole 7 is shallower, and drilling is easier. The diameter of the forming hole 8 is the same as the inner diameter of the reference anchor hole, and the depth of the forming hole 8 relative to the tunnel wall is the same as the depth of the reference anchor hole, so that the anchor hole formed by the reference hole 7 and the forming hole 8 can perform normal anchoring operations.

[0069] In this embodiment, the reference anchor hole is the required common anchor hole. The reference hole 7 can be drilled on the tunnel wall by the rock drill 5 using impact rock drilling. A hexagonal or round common drill rod is connected to the drill tail of the rock drill 5, a drill head is installed on the upper part for drilling holes, and then the quick-change drill rod is connected. The female thread end of the quick-change drill rod is connected to the first common drill rod, and the male thread end is connected to the drill tail of the rock drill 5. The drilling continues, and the quick-change drill rod is continuously connected in the same way to drill holes until the depth requirement is met. Finally, a reference hole 7 with an inner diameter larger than the inner diameter of the reference anchor hole is drilled, and the depth of the reference hole 7 is less than the depth of the reference anchor hole.

[0070] Then, withdraw the drill bit from the reference hole 7, replace the drill rod that meets the reference anchor hole depth requirement and the drill bit that meets the reference anchor hole inner diameter requirement, and coaxially drill the forming hole 8 at the bottom of the reference hole 7 until the depth of the forming hole 8 relative to the tunnel wall is the same as the depth of the reference anchor hole, and the reference hole 7 and the forming hole 8 form a stepped anchor hole.

[0071] See also Figures 1 to 3 As a specific embodiment of the anchor hole construction method provided by the present invention, the forming hole 8 is punched at the bottom of the reference hole 7 by impact drilling. The drilling efficiency of the forming hole 8 can be accelerated, and the speed of anchor hole construction can be further improved. The depth of the forming hole 8 is shallower than that of the bottom of the reference hole 7, which can avoid the breakage of the drill rod.

[0072] See also Figure 3 As a specific implementation of the anchor hole construction method provided by the present invention, a forming hole 8 is punched at the bottom of the reference hole 7, including:

[0073] Drill an intermediate hole 9 at the bottom of the reference hole 7, wherein the inner diameter of the intermediate hole 9 is smaller than the inner diameter of the reference hole 7 and larger than the inner diameter of the reference anchor hole, and the depth of the intermediate hole 9 relative to the tunnel wall is smaller than the depth of the reference anchor hole;

[0074] Punch a shaped hole 8 at the bottom of the middle hole 9;

[0075] The reference hole 7, the middle hole 9 and the forming hole 8 are connected in sequence to form an anchor hole.

[0076] The depth of the intermediate hole 9 and the forming hole 8 is shallow, which can avoid the breakage of the drill rod and facilitate the drilling by impact drilling. The reference hole 7, the intermediate hole 9 and the forming hole 8 are coaxial and connected in sequence to form a multi-stage stepped anchor hole. The intermediate hole 9 can be drilled by drilling or impact drilling.

[0077] See also Figures 4 to 15 As a specific embodiment of the anchor drilling vehicle provided by the present invention, an anchor drilling vehicle is provided, including: a vehicle body 4, a drill arm 1, a propulsion mechanism 2, a rock drill 5 and a drill rod replacement mechanism 6.

[0078] The drill arm 1 is provided on the vehicle body 4 and has a positioning end with adjustable position and angle. The propulsion mechanism 2 is provided on the positioning end and has a propulsion part. The rock drill 5 is provided on the propulsion part and is used to drill the reference hole 7 and the forming hole 8 in the above-mentioned anchor hole construction method by impact rock drilling. The drill rod replacement mechanism 6 is provided on the propulsion mechanism 2 and is located at the front side of the rock drill 5 and is used to clamp the drill rod of the rock drill 5.

[0079] Compared with the prior art, in the anchor drilling vehicle of the embodiment of the present invention, the propulsion mechanism 2 adjusts the position and angle through the positioning end of the drill arm 1, and the propulsion mechanism 2 is provided with a rock drill 5, which can drill a reference hole 7 on the tunnel wall by impact drilling, and then the drill rod replacement mechanism 6 can be used to quickly replace the drill rods and drill bits of different diameters to drill a forming hole 8 on the tunnel wall. The reference hole 7 and the forming hole 8 form an anchor hole, so that the anchor drilling vehicle of the embodiment of the present invention can efficiently drill anchor holes in harder areas on the tunnel wall.

[0080] See also Fig. 9 and Fig.15 As a specific implementation of the anchor drilling vehicle provided by the present invention, the drill rod replacement mechanism 6 includes: a clamping lifting mechanism 61 and a clamping mechanism 62.

[0081] The clamping and lifting mechanism 61 is arranged on the propulsion mechanism 2, located at the front side of the rock drill 5, and has a clamping and lifting end. The clamping mechanism 62 is arranged on the clamping and lifting end, and is used to clamp the drill rod on the rock drill 5. The clamping and lifting mechanism 61 is used to drive the clamping mechanism 62 to move along the radial direction of the drill rod.

[0082] When replacing the drill rod, the clamping mechanism 62 clamps the drill rod on the rock drill 5, and then the rock drill 5 releases the drill rod, and the rock drill 5 retreats through the propulsion part of the propulsion mechanism 2, so that the drill rod is separated from the rock drill 5. Then the clamping mechanism 62 descends through the clamping lifting mechanism 61, driving the clamping mechanism 62 to move along the radial direction of the drill rod, so that the drill rod is moved away from the front side of the rock drill 5, so that other drill rods can be installed on the rock drill 5.

[0083] In this embodiment, the clamping and lifting mechanism 61 includes a sliding housing 612, a fixed housing 611 sleeved outside the sliding housing 612, and a clamping and lifting hydraulic cylinder disposed in the fixed housing 611. The sliding housing 612 slides in the fixed housing 611 in the up-down direction, and the clamping and lifting hydraulic cylinder pushes the sliding housing 612 to slide along the fixed housing 611. The clamping mechanism 62 is installed on the top of the sliding housing 612, and the clamping mechanism 62 includes two clamping blocks 621 disposed horizontally opposite to each other. The two clamping blocks 621 are driven to approach each other by hydraulic cylinders, and the two clamping blocks 621 clamp the drill rod in the middle after approaching each other.

[0084] See also Figure 5 As a specific embodiment of the anchor drilling vehicle provided by the present invention, there are two drill arms 1, and the two drill arms 1 are respectively arranged on both sides of the vehicle body 4, and a propulsion mechanism 2 is provided on the positioning end of each drill arm 1.

[0085] See also Figures 4 to 8 As a specific embodiment of the anchor drilling vehicle provided by the present invention, the positioning end is adjusted in a plane perpendicular to the traveling direction of the vehicle body 4. With this structure, the telescopic swing arm 11 can be swung to the side of the vehicle body 4 and adjusted in the two-dimensional section of the tunnel, which makes the adjustment easier.

[0086] See also Figures 6 to 8 As a specific embodiment of the anchor drilling vehicle provided by the present invention, the drill arm 1 includes: a telescopic swing arm 11, a rotating mechanism 12 and a swing mechanism 13.

[0087] One end of the telescopic swing arm 11 is rotatably connected to the vehicle body 4, and the swing plane is perpendicular to the travel direction of the vehicle body 4. The rotating mechanism 12 is arranged on the swing end of the telescopic swing arm 11, and has a rotating seat 121. The rotating plane of the rotating seat 121 is parallel to the swing plane of the telescopic swing arm 11, and the rotating seat 121 forms a positioning end. The swing mechanism 13 is arranged on the rotating seat 121, and has a swingable propulsion mechanism mounting seat 131. The mounting axis 132 of the propulsion mechanism mounting seat 131 is parallel to the swing rotation axis of the propulsion mechanism mounting seat 131.

[0088] In this embodiment, when the drill arm 1 of the embodiment of the present invention is installed, one end of the telescopic swing arm 11 is rotatably connected to the vehicle body 4, and the propulsion mechanism 2 is installed on the propulsion mechanism mounting seat 131 along the installation axis 132. During the drilling operation, the position of the propulsion mechanism 2 in the tunnel is adjusted by the forward and backward movement of the vehicle body 4, and the position of the propulsion mechanism 2 is preliminarily determined in the two-dimensional section of the tunnel by the extension and swing of the telescopic swing arm 11. The angle of the propulsion mechanism 2 is adjusted by the rotation of the rotating seat 121 of the rotating mechanism 12. The installation axis 132 of the propulsion mechanism mounting seat 131 is parallel to the swinging rotation axis of the propulsion mechanism mounting seat 131, so that the position of the propulsion mechanism 2 can be further fine-tuned by the swing of the propulsion mechanism mounting seat 131 while keeping the angle of the propulsion mechanism 2 unchanged. The drill arm 1 of the present invention separates the angle adjustment and position adjustment of the propulsion mechanism 2, and can further fine-tune the position of the propulsion mechanism 2. The operation is convenient and quick, and the position and angle of the anchor hole can be accurately controlled, thereby improving work efficiency.

[0089] In this embodiment, the telescopic swing arm 11 can be axially telescopic, and its lower end is used to be hinged with the body 4 of the anchor drilling vehicle, and the upper end is a swing end. The rotating mechanism 12 is fixed on the swing end of the telescopic swing arm 11, and the rotating mechanism 12 is provided with a rotating seat 121, and the rotating seat 121 can be driven to rotate by a hydraulic cylinder. The rotating shaft of the rotating seat 121 is parallel to the rotating shaft of the telescopic swing arm 11 and the body 4, so that the rotating plane of the rotating seat 121 is parallel to the swing plane of the telescopic swing arm 11. The swing mechanism 13 is fixedly mounted on the rotating seat 121 and rotates with the rotating seat 121. The swing mechanism 13 is provided with a propulsion mechanism mounting seat 131, and the propulsion mechanism mounting seat 131 can be driven to rotate by a rotating oil cylinder. After the propulsion mechanism 2 is installed on the propulsion mechanism mounting seat 131, the position of the propulsion axis of the pushing mechanism is the mounting axis 132 of the propulsion mechanism mounting seat 131. The installation axis 132 of the propulsion mechanism mounting seat 131 is parallel to the swing axis of the propulsion mechanism mounting seat 131, so that when the propulsion mechanism mounting seat 131 swings, the position of the propulsion mechanism 2 installed on the propulsion mechanism mounting seat 131 changes while the direction of the propulsion axis remains unchanged.

[0090] See also Figures 6 to 8 As a specific embodiment of the anchor drilling vehicle provided by the present invention, the swing axis of the propulsion mechanism mounting seat 131 is parallel to the rotation plane of the rotating seat 121. In this structure, the installation axis 132 of the propulsion mechanism mounting seat 131 is parallel to the swing axis of the propulsion mechanism mounting seat 131, and the swing axis of the propulsion mechanism mounting seat 131 is parallel to the rotation plane of the rotating seat 121, so that the installation axis 132 of the propulsion mechanism mounting seat 131 is always parallel to the rotation plane of the rotating seat 121, and it is more convenient to adjust the angle of the propulsion mechanism 2 installed along the installation axis 132 by rotating the rotating seat 121.

[0091] More specifically, the rotating mechanism 12 is used to rotate the propulsion mechanism mounting seat 131 to the mounting axis 132 and the telescopic swing arm 11 to be folded, and when the mounting axis 132 and the telescopic swing arm 11 are folded, the swinging mechanism 13 is used to swing the propulsion mechanism mounting seat 131 to the front or rear side of the telescopic swing arm 11.

[0092] In this embodiment, when in use, the propulsion mechanism 2 is installed on the propulsion mechanism mounting seat 131 along the mounting axis 132, and the rotating mechanism 12 rotates the propulsion mechanism mounting seat 131 to the mounting axis 132 and the telescopic swing arm 11 to fold, so that the propulsion mechanism 2 and the telescopic swing arm 11 are folded. The two sides of the telescopic swing arm 11 in the direction of its own rotation axis are the front side and the rear side respectively. The swing mechanism 13 can swing the propulsion mechanism mounting seat 131 to the front side or the rear side of the telescopic swing arm 11, so that the swing mechanism 13 can swing the propulsion mechanism 2 on the propulsion mechanism mounting seat 131 to the front side or the rear side of the telescopic swing arm 11, thereby changing the folding direction of the propulsion mechanism 2 and the telescopic swing arm 11, and preventing the propulsion mechanism 2 and the telescopic swing arm 11 from protruding out of the vehicle body 4 after being folded, resulting in an increase in the volume of the vehicle body 4 and affecting traffic. For example, the telescopic swing arm 11 is rotatably installed on the side of the vehicle body 4, the swing plane of the telescopic swing arm 11 and the rotation plane of the rotating seat 121 of the rotating mechanism 12 are perpendicular to the moving direction of the vehicle body 4, and the rotating mechanism 12 can fold the propulsion mechanism 2 and the telescopic swing arm 11 in the width direction of the vehicle body 4. At this time, the propulsion mechanism 2 and the telescopic swing arm 11 will increase the width of the anchor drilling vehicle. In this case, the propulsion mechanism mounting seat 131 can be swung to the front or rear side of the telescopic swing arm 11 through the swing mechanism 13, so as to reduce the width of the anchor drilling vehicle.

[0093] More specifically, the rotating mechanism 12 includes: a bent arm 122 and a rotating telescopic unit 123. The bent arm 122 is rotatably arranged on the swing end of the telescopic swing arm 11, the rotating shaft of the bent arm 122 is perpendicular to the swing plane of the telescopic swing arm 11, and the rotating seat 121 is connected to the bent arm 122. The rotating telescopic unit 123 is arranged on the telescopic swing arm 11, and the telescopic end is hinged to the swing end of the bent arm 122, and is used to drive the bent arm 122 to drive the rotating seat 121 to rotate. The rotating telescopic unit 123 drives the bent arm 122 to drive the rotating seat 121 to rotate, and the structure is simple. A low-cost hydraulic cylinder can be used as the rotating telescopic unit 123, which has a stronger bearing capacity and more stable operation.

[0094] In this embodiment, the telescopic driving force and telescopic length of the rotating telescopic unit 123 can be adjusted by designing the length of the curved arm 122 to meet the requirements of the rotation range of the rotating seat 121. Specifically, the rotating seat 121 can be directly connected to the free end of the curved arm 122, or can be connected to the rotating shaft of the curved arm 122. The curved arm 122 is curved so that the free end of the curved arm 122 is perpendicular to the telescopic end of the rotating telescopic unit 123.

[0095] More specifically, two oppositely arranged ear plates 125 are provided on the swing end of the telescopic swing arm 11, a main shaft 124 is provided between the two ear plates 125, the bent arm 122 is located between the two ear plates 125 and connected to the main shaft 124; one end of the main shaft 124 passes through the two ear plates 125, and the rotating seat 121 is located outside the two ear plates 125 and connected to the end of the main shaft 124 passing through the two ear plates 125. This structure makes the overall structure more compact and can increase the connection strength between the bent arm 122 and the swing end of the telescopic swing arm 11.
