Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering equipment, and particularly relates to a shank adapter for an anchor rod and an anchor rod drilling device. Background Art

[0002] Currently, for anchoring construction, an anchor rod drilling device is required. The anchor rod drilling device consists of an anchor rod, a drill rig, and a connecting sleeve, and is constructed by drilling one by one. After each anchor rod is drilled, the connection between the anchor rod and the drill rig needs to be removed to install and drill the next anchor rod until the predetermined depth is reached. During the construction process, the drill rig and the anchor rod are fixedly connected through a shank adapter. When it is necessary to remove the anchor rod and install the next one, a hydraulic clamp is used to hold and fix the anchor rod, and the shank of the drill rig is rotated in the reverse direction to disconnect it from the anchor rod, thereby achieving disassembly.

[0003] However, since the diameter of the shank of the drill rig is smaller than that of the anchor rod, and the hardness of the anchor rod is much lower than that of the shank of the drill rig, it is easy for the anchor rod to adhere to the shank adapter, increasing the thread bearing capacity. As a result, when the drill rig drives the anchor rod to drill, the anchor rod and the shank adapter become tighter and tighter. In this way, during the actual disassembly process, most of the time, the shank adapter is disconnected from the shank of the drill rig, while the connection between the shank adapter and the anchor rod is very tight, and it takes a lot of time for manual disassembly. Coupled with the characteristic that the anchor rod needs to be frequently disassembled during anchoring construction, a large amount of time is spent on disassembly.

[0004] In view of this, the present invention patent is specifically proposed. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a shank adapter for an anchor rod and an anchor rod drilling device, which can solve the problem that during the drilling process of the anchor rod, the anchor rod and the shank adapter become tighter and tighter, resulting in the inability to disconnect from the shank adapter when disassembling the anchor rod. Specifically, the following technical solutions are adopted:

[0006] A shank adapter for an anchor rod, comprising:

[0007] A sleeve body, both ends of the sleeve body are respectively provided with a first connecting threaded hole and a second connecting threaded hole. The internal threads of the first connecting threaded hole and the second connecting threaded hole have the same helix direction. The first connecting threaded hole is used to connect the anchor rod, and the second connecting threaded hole is used to connect the drill rig;

[0008] A locking block, which is arranged at the inner end of the first connecting threaded hole. The anchor rod rotates and drills under the drive of the drill rig, and the locking block abuts against the anchor rod to prevent the anchor rod from further screwing and locking with the first connecting threaded hole during the rotation drilling process.

[0009] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. A locking block mounting hole is arranged inside the sleeve body close to the side of the first connecting threaded hole passage. The locking block mounting hole communicates with the first connecting threaded hole passage, and the locking block is installed in the locking block mounting hole through the first connecting threaded hole passage.

[0010] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. The locking block mounting hole is a polygonal hole, and the outer contour of the locking block is a polygon adapted to the polygonal hole.

[0011] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. The lengths of the first connecting threaded hole passage and the second connecting threaded hole passage are the same.

[0012] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. The first connecting threaded hole passage has a first hole passage section and a second hole passage section. The first hole passage section is located inside the sleeve body, the locking block is installed in the first hole passage section, and the anchor rod is connected to the second hole passage section; the length of the second hole passage section is equal to the length of the second connecting threaded hole passage.

[0013] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. The locking block has a "one"-shaped through hole or a "cross"-shaped through hole penetrating along the central axis.

[0014] As an alternative embodiment of the present invention, a shank adapter of an anchor rod of the present invention is provided. The locking block is a rubber block.

[0015] The present invention also provides an anchor rod drilling device having the shank adapter of the anchor rod, including:

[0016] A drill rig having a shank, and the shank is threadedly connected to the second connecting threaded hole passage of the shank adapter of the anchor rod;

[0017] An anchor rod, which is threadedly connected to the first connecting threaded hole passage of the shank adapter of the anchor rod.

[0018] As an alternative embodiment of the present invention, an anchor rod drilling device of the present invention includes a hydraulic tong. The anchor rod passes through the jaws of the hydraulic tong, and the anchor rod is clamped by the jaws of the hydraulic tong, and the drill rig is controlled to rotate in the reverse direction to realize the disassembly between the anchor rod and the shank adapter of the anchor rod.

[0019] As an alternative embodiment of the present invention, an anchor rod drilling device of the present invention includes a base, and the drill rig and the hydraulic tong are both installed on the base.

[0020] Compared with the prior art, the beneficial effects of the present invention:

[0021] A shank adapter of the present invention is provided with a locking block at the inner end of the first connecting threaded channel. The locking block abuts against the end of the bolt. In this way, when the drilling rig drives the shank adapter to drive the bolt to drill, the locking block blocks the further rotation and locking of the bolt, preventing the bolt and the shank adapter from becoming tighter and tighter during rotation. However, the second connecting threaded channel and the drilling rig are not blocked and become tighter and tighter during rotation. When disassembling the bolt, a hydraulic clamp is used to clamp and fix the bolt, and the drilling rig is controlled to reverse, making it easier for the bolt and the shank adapter to disengage, thus completing the disassembly of the bolt and installing a new bolt. Therefore, when the shank adapter of the present invention is used for connecting the drilling rig and the bolt, it is easier to disassemble the bolt, saving manpower and material resources and greatly improving the efficiency of the anchoring construction.

In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0029] See Figure 1 As shown, a kind of anchor rod shank adapter of this embodiment includes:

[0030] A sleeve body 101, both ends of the sleeve body 101 respectively have a first connecting threaded hole 102 and a second connecting threaded hole 103. The internal threads of the first connecting threaded hole 102 and the second connecting threaded hole 103 have the same helix direction. The first connecting threaded hole 102 is used to connect the anchor rod, and the second connecting threaded hole 103 is used to connect the drill.

[0031] A locking block 105, the locking block 105 is arranged at the inner end of the first connecting threaded hole 102. The anchor rod rotates and drills under the drive of the drill. The locking block 105 abuts against the anchor rod and is used to prevent the anchor rod from further screwing and locking with the first connecting threaded hole 102 during the rotation drilling process.

[0032] For a kind of anchor rod shank adapter of this embodiment, by arranging a locking block 105 at the inner end of the first connecting threaded hole 102, and the locking block 105 abuts against the end of the anchor rod. In this way, when the drill drives the anchor rod shank adapter to drive the anchor rod to drill, the locking block 105 blocks the further screwing and locking of the anchor rod, avoiding the anchor rod and the anchor rod shank adapter from screwing tighter and tighter, while there is no blockage between the second connecting threaded hole 103 and the drill and they screw tighter and tighter. When disassembling the anchor rod, use a hydraulic clamp to hold the anchor rod firmly, control the drill to reverse, and it is easier for the anchor rod to be disengaged from the anchor rod shank adapter to complete the disassembly of the anchor rod and install a new anchor rod. Therefore, for a kind of anchor rod shank adapter of this embodiment, when used for connecting between the drill and the anchor rod, it is easier to disassemble the anchor rod, saving manpower and material resources and greatly improving the efficiency of the anchoring construction.

[0033] As an optional implementation manner of this embodiment, for a kind of anchor rod shank adapter of this embodiment, a locking block installation hole 104 is arranged inside the sleeve body 101 near the side of the first connecting threaded hole 102. The locking block installation hole 104 is communicated with the first connecting threaded hole 102, and the locking block 105 is installed in the locking block installation hole 104 through the first connecting threaded hole 102.

[0034] Since the locking block 105 abuts against the end of the anchor rod, pressure or friction will be generated during the construction process. Therefore, the locking block 105 of this embodiment is installed in the locking block installation hole 104 for easy disassembly and replacement, thereby ensuring the reliability of the locking block 105 during operation.

[0035] Specifically, for an anchor rod shank adapter of this embodiment, the locking block installation hole 104 is a polygonal hole, and the outer contour of the locking block 105 is a polygon adapted to the polygonal hole. In this way, the locking block 105 can be limited from rotating in the locking block installation hole 104, avoiding wear and extending the service life.

[0036] Furthermore, for an anchor rod shank adapter of this embodiment, the lengths of the first connecting threaded hole passage 102 and the second connecting threaded hole passage 103 are the same. In this way, the connection tightness between the first connecting threaded hole passage 102 and the anchor rod, as well as the connection tightness between the second connecting threaded hole passage 103 and the drill rig, can be ensured.

[0037] As an alternative implementation of this embodiment, for an anchor rod shank adapter of this embodiment, the first connecting threaded hole passage 102 has a first hole passage section and a second hole passage section. The first hole passage section is located within the sleeve body 101, the locking block 105 is installed within the first hole passage section, and the anchor rod is connected to the second hole passage section; the length of the second hole passage section is equal to the length of the second connecting threaded hole passage 103. In this way, the connection tightness between the second hole passage section and the anchor rod, as well as the connection tightness between the second connecting threaded hole passage 103 and the drill rig, can be ensured. At the same time, since the locking block 105 is installed within the first hole passage section, it can prevent further tightening between the anchor rod and the second hole passage section, while the second connecting threaded hole passage 103 becomes tighter and tighter when connected to the drill rig.

[0038] Furthermore, the outer peripheral wall of the locking block 105 of this embodiment has an external thread that is threadedly connected to the first hole passage section. After the locking block 105 is screwed into the first hole passage section, for easy disassembly and replacement, the locking block 105 of this embodiment has a "one"-shaped through hole or a "cross"-shaped through hole that penetrates along the central axis. In this way, the locking block 105 can be disassembled using a "one"-shaped screwdriver or a "cross"-shaped screwdriver.

[0039] As an alternative implementation of this embodiment, for an anchor rod shank adapter of this embodiment, the locking block 105 is a rubber block. The rubber block has elasticity and can avoid hard contact with the anchor rod and mutual damage.

[0040] See Figure 2 As shown, this embodiment also provides an anchor rod drilling device having the anchor rod shank adapter, including:

[0041] The drill rig 200 has a tool shank 201, and the tool shank 201 is threadedly connected to the second connecting threaded hole 103 of the rock bolt tool shank sleeve 100.

[0042] The rock bolt 300 is threadedly connected to the first connecting threaded hole 102 of the rock bolt tool shank sleeve 100.

[0043] In the rock bolt drilling device of this embodiment, when the drill rig 200 drives the rock bolt tool shank sleeve 100 to drive the rock bolt 300 to drill, the locking block 105 blocks the further rotation and locking of the rock bolt 300, avoiding the tighter and tighter rotation between the rock bolt 300 and the rock bolt tool shank sleeve 100, while the second connecting threaded hole 103 and the drill rig 200 are not blocked and rotate tighter and tighter. When disassembling the rock bolt 300, use the hydraulic tongs 400 to clamp and fix the rock bolt 300, control the drill rig 200 to reverse, and it is easier to disconnect between the rock bolt 300 and the rock bolt tool shank sleeve 100 to complete the disassembly of the rock bolt 300 and install a new rock bolt 300. Therefore, in the rock bolt drilling device of this embodiment, when connecting the drill rig 200 and the rock bolt 300, it is easier to disassemble the rock bolt 300, saving manpower and material resources and greatly improving the efficiency of the anchoring construction.

[0044] Furthermore, a rock bolt drilling device of this embodiment includes a hydraulic tongs 400. The rock bolt 300 passes through the jaws of the hydraulic tongs 400, and the rock bolt 300 is clamped by the jaws of the hydraulic tongs 400, and the reverse rotation of the drill rig 200 is controlled to achieve the disassembly between the rock bolt 300 and the rock bolt tool shank sleeve 100.

[0045] Furthermore, a rock bolt drilling device of this embodiment includes a base 500, and the drill rig 200 and the hydraulic tongs 400 are both installed on the base 500.
