[0002] In mineral mining construction, it is generally necessary to open a mine tunnel in the mountain. During the excavation process, the inner wall of the mine tunnel needs to be temporarily supported in time. The support method often adopts the anchor support method. Generally, it is necessary to drill holes in the soil layer, insert fillers, and drill anchors. Generally, the anchors are divided into multiple parts to facilitate the transportation and use of the anchors.

[0003] Anchor rods are generally divided into four parts: drill bit, rod body, pad and locking nut. The anchor rod can be divided into multiple parts to facilitate the transportation of the anchor rod into the mine, and the drilling operation of the anchor rod is driven by a rotating anchor rod driving device. The length of the anchor rod is adjusted according to the use requirements to cope with the use requirements of anchor rods in different geological conditions and mine mining shapes in various regions. The connection between the rod bodies often requires the use of tools such as connecting sleeves, and then the operator needs to perform various connection and installation operations to connect the rod bodies stably and firmly, which is very troublesome. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an anchor rod that is easy to assemble, so as to solve the problems raised in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] An anchor rod that is easy to assemble includes an anchor rod, which is mainly divided into two parts: a drill bit and a plurality of rod bodies. The top end of the rod body is provided with a threaded shaft, and the threaded shaft and the corresponding rod body are cast as one piece. The bottom end of the rod body and the bottom end of the drill bit are both provided with a threaded groove. The outer peripheral side of the threaded groove and the outer peripheral side of the corresponding threaded shaft are jointly provided with a positioning component. The top of the threaded groove is provided with a driving component, and the driving component drives the positioning component to operate.

[0007] In a preferred example, the utility model can be further configured as follows: the positioning assembly includes a plurality of positioning rods, a plurality of slide grooves are relatively formed on the inner wall of the threaded groove, the positioning rods are inserted into the corresponding slide grooves, and the positioning rods are in contact with the inner wall of the corresponding slide grooves, a plurality of positioning grooves are relatively formed on the outer peripheral wall of the threaded shaft at positions corresponding to the slide grooves, a guide groove in the shape of a T is formed in the positioning rod, and a guide rod in the shape of a T is slidably inserted into the guide groove.

[0008] By adopting the above technical solution, the guide rod and the guide groove cooperate with each other to constrain the moving trajectory of the positioning rod, thereby preventing the positioning rod from falling out of the circular groove.

[0009] In a preferred example, the utility model can be further configured as follows: a plurality of storage grooves are relatively provided on the outer wall of the rod body and at the positions of the corresponding slide grooves on the outer side of the drill bit, and the interior of the storage grooves is communicated with the interior of the corresponding slide grooves, and bolts are threadedly passed through the inner threads of the storage grooves, and the bolts are integrally cast with the corresponding guide rods.

[0010] By adopting the above technical solution, the connection state between the slide groove and the outside world is controlled through the mutual cooperation of the bolts, the guide rod and the guide groove, so that the positioning rod can be pulled into the slide groove through the bolts and the guide rod, and the constraint state of the threaded shaft is released, so that the device can be disassembled.

[0011] The utility model can be further configured as follows in a preferred example: the driving component includes a push plate, a circular groove is provided at the top of the threaded groove, and the interior of the circular groove is communicated with the interior of the corresponding threaded groove, the push plate is slidably installed in the corresponding circular groove, a spring is provided between the push plate and the inner wall of the corresponding circular groove, and the two ends of the spring are respectively fixedly connected to the corresponding push plate and the inner wall of the corresponding circular groove, a sealing ring is installed on the outer peripheral wall of the push plate, and the interior of the circular groove is communicated with the interior of the corresponding circular groove through a connecting hole.

[0012] By adopting the above technical solution, through the mutual cooperation of the push plate, the sealing ring and the connecting hole, the air pressure in the circular groove can be increased synchronously when the threaded shaft is screwed into the threaded hole, thereby pushing the positioning rod out of the slide groove, and when the push plate loses the support and resistance of the threaded shaft, the push plate is pushed back to its original position by the spring, without the operator having to perform other operations, thereby facilitating the disassembly and assembly of the device.

[0013] In a preferred example, the utility model can be further configured as follows: an arc block is provided at the top end of the threaded shaft, and the arc block and the corresponding threaded shaft are cast in one piece.

[0014] By adopting the above technical solution, the positioning rod is squeezed into the slide groove through the mutual interference between the arc block and the arc surface of the positioning rod, thereby preventing the rod from extending too early and affecting the insertion of the threaded shaft into the threaded groove.

[0015] In a preferred example, the utility model can be further configured as follows: an annular groove is provided at the bottom end of the rod body and the bottom end of the drilling oil, and the annular groove is located on the outer peripheral side of the corresponding threaded groove; a soft ring is fixedly installed at the top end of the rod body, and the soft ring is located on the outer peripheral side of the corresponding threaded shaft.

[0016] By adopting the above technical solution, the gaps between the joints of the rod body and the gaps between the rod body and the drill bit are sealed through the cooperation between the annular groove and the soft ring, preventing external cement or water from flowing into the gaps and contacting the threaded shaft, causing the threaded shaft to rust and thus affecting the disassembly of the device.

[0017] In summary, the present invention includes at least one of the following beneficial technical effects:

[0018] 1. When using the anchor rod, screw the threaded shaft into the threaded groove.

The operation is simple and no other tools are required. At the same time, there will be no raised parts around the anchor rod, which will affect the anchor rod from drilling into the filling material in the hole on the inner wall of the mine tunnel.

[0019] 2. Through the cooperation between the annular groove and the soft ring, the gaps between the joints of the rod body and the gaps between the rod body and the drill bit are blocked to prevent external cement or water from flowing into the gaps and contacting the threaded shaft, causing the threaded shaft to rust, resulting in a significant increase in friction between the threaded shaft and the inner wall of the threaded groove, thereby affecting the disassembly of the device.

DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1-5 The utility model discloses an anchor rod that is easy to assemble, including an anchor rod 1. The anchor rod 1 is mainly divided into four parts: a drill bit 2, a plurality of rod bodies 3, a pad and a locking nut. A threaded shaft 6 is provided at the top of the rod body 3, and the threaded shaft 6 is integrally cast with the corresponding rod body 3. A threaded groove 7 is provided at the bottom end of the rod body 3 and the bottom end of the drill bit 2. An arc block 8 is provided at the top of the threaded shaft 6, and the arc block 8 is integrally cast with the corresponding threaded shaft 6. An annular groove 9 is provided at the bottom end of the rod body 3 and the bottom end of the drill bit, and the annular groove 9 is located on the outer peripheral side of the corresponding threaded groove 7. A soft ring 10 is fixedly installed at the top end of the rod body 3, and the soft ring 10 is located on the outer peripheral side of the corresponding threaded shaft 6, and the soft ring 10 is a rubber ring. The positioning rod 42 is squeezed into the slide groove 41 by the mutual interference between the arc block 8 and the arc surface of the positioning rod 42, and the gaps between the joints of the rod body 3 and the joints between the rod body 3 and the drill bit 2 are blocked by the mutual cooperation between the annular groove 9 and the soft ring 10.

[0029] The outer circumference of the thread groove 7 and the outer circumference of the corresponding threaded shaft 6 are jointly provided with a positioning assembly 4. The positioning assembly 4 includes a plurality of positioning rods 42, and a plurality of slide grooves 41 are relatively opened on the inner wall of the thread groove 7. The positioning rods 42 are inserted into the corresponding slide grooves 41, and the positioning rods 42 are in contact with the inner wall of the corresponding slide groove 41. A sealing ring is installed on the outer circumference of the positioning rod 42 to block the positioning rod 42 and the inner wall of the corresponding slide groove 41. The corner of the positioning rod 42 close to the opening of the corresponding slide groove 41 is set in an arc shape. The outer circumference of the threaded shaft 6 is relatively opened at the position corresponding to the slide groove 41. The positioning rod 42 is provided with a guide groove 44 in a T-shaped configuration, and a guide rod 45 in a T-shaped configuration is slidably penetrated in the guide groove 44. A plurality of storage grooves 46 are relatively provided on the outer peripheral wall of the rod body 3 and at the positions corresponding to the slide groove 41 on the outer peripheral side of the drill bit 2, and the interior of the storage groove 46 is communicated with the interior of the corresponding slide groove 41. A bolt 47 is penetrated through the inner thread of the storage groove 46, and the bolt 47 is integrally cast with the corresponding guide rod 45, and the bolt 47 is a hexagon socket bolt 47. The moving track of the positioning rod 42 is constrained by the mutual cooperation of the guide rod 45 and the guide groove 44, and the communication state of the slide groove 41 with the outside is controlled by the mutual cooperation of the bolt 47, the guide rod 45 and the guide groove 44, so that the positioning rod 42 can be pulled out of the positioning groove 43 by the bolt 47 and the guide rod 45.

[0030] A driving assembly 5 is provided at the top of the thread groove 7, and the driving assembly 5 drives the positioning assembly 4 to operate. The driving assembly 5 includes a push plate 52, a circular groove 51 is provided at the top of the thread groove 7, and the interior of the circular groove 51 is communicated with the interior of the corresponding thread groove 7, the push plate 52 is slidably installed in the corresponding circular groove 51, a spring 53 is provided between the push plate 52 and the inner wall of the corresponding circular groove 51, and the two ends of the spring 53 are respectively fixedly connected to the corresponding push plate 52 and the inner wall of the corresponding circular groove 51, a sealing ring 54 is provided on the outer peripheral wall of the push plate 52 to block the gap between the push plate 52 and the inner wall of the corresponding circular groove 51, and the interior of the circular groove 51 is communicated with the interior of the corresponding circular groove 51 through a connecting hole 55. Through the cooperation between the push plate 52, the sealing ring 54 and the connecting hole 55, the air pressure in the circular groove 51 can be increased synchronously when the threaded shaft 6 is screwed into the threaded hole, so that the positioning rod 42 is pushed out of the slide groove 41, and when the push plate 52 loses the support and resistance of the threaded shaft 6, the spring 53 pushes the push plate 52 to return to its original position.

[0031] The implementation principle of the above embodiment is as follows: in the process of using the anchor rod 1, the installation of the pad and the locking nut is completed according to the existing method of using the anchor rod 1, and then the threaded shaft 6 on the anchor rod 1 is screwed into the threaded groove 7 at the bottom end of the drill bit 2. After the push plate 52 of the arc block 8 contacts each other, as the threaded shaft 6 is screwed in, the push plate 52 moves upward, thereby squeezing the excess gas in the circular groove 51 into the connecting hole 55, and then introduced into the circular groove 51 through the connecting hole 55, so that the air pressure in the circular groove 51 increases, thereby pushing the positioning rod 42 in the direction of the threaded shaft 6. Due to the mutual interference between the positioning rod 42 and the threaded shaft 6, when the threaded shaft 6 is not completely screwed into the threaded groove 7, the positioning rod 42 will not extend out of the slide groove 41. After the threaded shaft 6 is completely screwed into the threaded hole, the positioning groove 43 is aligned with the slide groove 41, so that part of the positioning rod 42 is inserted into the positioning groove 43. Due to the mutual interference between the positioning rod 42 and the inner wall of the positioning groove 43 and the inner wall of the slide groove 41, the threaded shaft 6 will not rotate in the threaded groove 7.

[0032] It should be noted that, when the threaded shaft 6 is being screwed into the threaded groove 7, the gas in the threaded groove 7 pushes the push plate 52 to move upward by a certain distance, causing part of the gas in the circular groove 51 to flow into the circular groove 51, thereby causing the threaded shaft 6 not to move to the slide groove 41 and part of the positioning rod 42 to extend from the slide groove 41. First, the arc surface of the arc block 8 will conflict with the arc surface of the positioning rod 42, causing the positioning rod 42 to retract into the slide groove 41, thereby allowing the threaded shaft 6 to be screwed into the threaded groove 7 normally.

[0033] When the threaded shaft 6 is screwed into the slide groove 41, the soft tube is synchronously driven to be inserted into the annular groove 9. The inner wall of the annular groove 9 and the rod body 3 are squeezed by the soft ring 10 on both sides, so that the soft ring 10 is deformed and tightly attached to the inner wall of the annular groove 9, thereby sealing the gap at the joint. After the first rod body 3 is installed, the locking nut and the gasket are removed according to the above and the locking nut and the gasket are installed on the next rod body 3, and then the threaded shaft 6 on the next rod body 3 is screwed into the threaded groove 7 of the previous rod body 3, and the installation of the subsequent multiple rod bodies 3 is completed in sequence until the anchor rod 1 reaches the required length;

[0034] When dismantling the rod bodies 3 or the rod body 3 and the drill bit 2, insert a hexagonal wrench into the storage groove 46 and rotate the bolt 47 in the opposite direction to release the threaded connection between the bolt 47 and the storage groove 46. The excess gas in the slide groove 41 is discharged from the storage groove 46, reducing the air pressure in the slide groove 41. Due to the push of the flowing gas, the bolt 47 is pushed out of the storage groove 46. The operator pulls the guide rod 45 outward to pull the positioning rod 42 out of the positioning groove 43, releasing the restraining limit state of the positioning rod 42 on the threaded shaft 6. The threaded shaft 6 can be screwed out of the threaded groove 7 by rotating the threaded shaft 6 in the opposite direction, completing the disassembly between the rod bodies 3 or between the rod body 3 and the drill bit 2.

[0035] It should be noted that the threaded shaft 7 can be rotated synchronously with the rotation of the anchor 1 by the existing anchor driving device.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
