Description

Technical Field

[0001] This utility model relates to the field of drilling rig anchor bolt technology, specifically an anchor bolt for drilling rigs. Background Technology

[0002] Anchor bolt drilling rigs, also known as anchoring drilling rigs in some places, are drilling tools used in anchor bolt support work in coal mine roadways. They have significant advantages in improving support effectiveness, reducing support costs, accelerating roadway construction, reducing auxiliary transportation volume, alleviating labor intensity, and increasing roadway cross-sectional utilization. The anchor bolts used with the drilling rig need to be screwed together.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: existing anchor rods for drilling rigs are mostly connected by threaded posts and internal threads, and both the threaded posts and internal threads are integrally formed with the anchor rod. However, during long-term use, there is a need for frequent disassembly and assembly of the anchor rod for transportation. However, frequent disassembly and assembly and use can easily cause stripping and damage. At this time, the current situation is to discard and replace it with a new one, which results in relatively high cost of anchor rod use. Therefore, we propose an anchor rod for drilling rigs. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor rod for drilling rigs, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anchor rod for drilling rigs, comprising an anchor rod body, wherein there are two sets of anchor rod bodies, a connecting block is installed at one end of the anchor rod body, and a threaded cylinder is installed at the other end of the anchor rod body;

[0006] The connecting block includes a limiting cylinder and a threaded post, with the threaded post fixed inside the limiting cylinder;

[0007] The threaded cylinder is located inside the anchor bolt body, and several sets of uniformly arrayed locking blocks are fixedly installed on the outer walls of both the threaded cylinder and the limiting cylinder.

[0008] A slot is provided on the outer side of the anchor bolt body near the slot, and a threaded groove is provided on the side of the anchor bolt body near the slot.

[0009] A screw rod is movably inserted through the center of the locking block. The inner end of the screw rod is screwed into a threaded groove via an external thread. The locking block, the groove, and the screw rod can be used together. During the use of anchor rods for drilling rigs, if frequent disassembly and assembly damages the connecting thread mechanism and renders it unusable, the screw rod can be rotated until it separates from the threaded groove. The screw rod can then be completely pulled out. At this point, the locking block and the groove are separated. Force can then be applied to pull out the damaged threaded cylinder or limiting cylinder, and new components can be selectively replaced. The new threaded cylinder can then be screwed into the threaded post, allowing the anchor rod to continue to be used. Compared to the current situation where anchor rods are discarded once damaged, this reduces the cost of using anchor rods and provides a more ideal performance.

[0010] As an optional solution to the technical solution of this application, the shape of the card slot is adapted to the contour of the card block, and the card block fits into the card slot, which can make the card block and the card slot fit together to achieve a stable card position effect, and multiple sets of card blocks and card slots effectively ensure the connection strength.

[0011] As an optional solution to the technical solution of this application, an indicator sticker is fixedly installed on the front side of a set of anchor bolt bodies, and a waterproof membrane is integrally formed on the outer side of the indicator sticker. The guide text on the indicator sticker can inform the operator of the corresponding procedures, making it easier for novice personnel to learn and use, and facilitating later replacement.

[0012] As an optional solution to the technical solution of this application, an adjustment groove is provided in the middle of the end face of the screw away from the thread groove, and the adjustment groove is a cross-shaped structure. The end of the adjustment groove can be inserted into the cross-shaped adjustment groove by a screwdriver for the disassembly and assembly of the screw.

[0013] As an optional solution to the technical solution of this application, the outer shapes of the threaded cylinder and the limiting cylinder are adapted to the inner opening contour of the anchor bolt body, and the threaded cylinder and the limiting cylinder are both attached to the inner wall of the anchor bolt body on the same side. The cylinder body is adapted to avoid the cylinder body from shaking or tilting, thereby avoiding damage.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model discloses an anchor rod for drilling rigs. By incorporating a locking block, a locking groove, and a screw, if frequent disassembly and reassembly damage the connecting thread mechanism during use, rendering the anchor rod unusable, the screw can be rotated until it separates from the thread groove. The screw can then be completely pulled out, at which point the locking block and locking groove are separated. Force can then be applied to pull out the damaged threaded cylinder or limiting cylinder, selectively replacing it with a new component. The new threaded cylinder can then be screwed onto the threaded post, allowing the anchor rod to continue to be used. Compared to the current practice of discarding anchor rods once damaged, this design reduces the cost of using anchor rods and provides a more ideal performance. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-3This utility model provides a technical solution: an anchor rod for drilling rigs, including an anchor rod body 1, which consists of two sets. One set of anchor rod bodies 1 has an indicator sticker 13 fixedly installed on its front side, and the outer side of the indicator sticker 13 is integrally formed with a waterproof membrane. The guide text on the indicator sticker 13 informs operators of the corresponding procedures, facilitating learning and use for beginners and simplifying future replacements. A connecting block 2 is installed at one end of the anchor rod body 1, and a threaded cylinder 3 is installed at the other end. The connecting block 2 includes a limiting cylinder 4 and a threaded post 41, with the threaded post 41 fixed inside the limiting cylinder 4. The threaded cylinder 3 is located inside the anchor rod body 1. Several sets of evenly arrayed locking blocks 5 are fixedly installed on the outer walls of both the threaded cylinder 3 and the limiting cylinder 4. The shapes of the threaded cylinder 3 and the limiting cylinder 4 are adapted to the internal opening contour of the anchor rod body 1, and both the threaded cylinder 3 and the limiting cylinder 4 are fitted together. The inner wall of the anchor rod body 1 on the same side is designed to fit the cylinder, which can prevent the cylinder from shaking or tilting, thus avoiding damage. A groove 12 is opened on the outer side of the side end face of the anchor rod body 1 near the locking block 5. The shape of the groove 12 is adapted to the contour of the locking block 5, and the locking block 5 fits into the groove 12, which can make the locking block 5 fit into the groove 12, thereby achieving a stable locking effect. Multiple sets of locking blocks 5 and locking grooves 12 effectively ensure the connection strength. A threaded groove 11 is opened on the side of the anchor rod body 1 near the locking groove 12. A screw rod 51 is movably inserted through the middle of the locking block 5. An adjustment groove is opened in the middle of the end face of the screw rod 51 away from the threaded groove 11. The adjustment groove has a "+" shaped structure. It can be inserted into the cross-shaped adjustment groove with a screwdriver for the installation and removal of the screw rod 51. The inner end of the screw rod 51 is screwed into the threaded groove 11 through the external thread.

[0023] In this technical solution, components such as the locking block 5, the locking groove 12, and the screw 51 can be used together. During the use of the anchor rod for the drilling rig, if frequent disassembly and assembly cause damage to the connecting thread mechanism and render it unusable, the screw 51 can be rotated until it separates from the thread groove 11. The screw 51 can then be completely pulled out. At this point, the locking block 5 is separated from the locking groove 12. Force can then be applied to pull out the damaged threaded cylinder 3 or the limiting cylinder 4, and new components can be selectively replaced. The new threaded cylinder 3 can then be screwed onto the threaded post 41, allowing the anchor rod to continue to be used. Compared to the current situation where the anchor rod is discarded once damaged, this reduces the cost of using the anchor rod and provides a more ideal performance.

[0024] Working principle: It should be noted that this utility model is an anchor rod for drilling rigs. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0025] When using a drilling rig anchor bolt, a suitable number of anchor bolts are transported to the installation area, then the anchor bolts are joined together and their ends are connected to the drive end of the drilling rig for drilling operations.

[0026] By incorporating a locking block 5, a locking groove 12, and a screw 51, if frequent disassembly and assembly during the use of anchor bolts for drilling rigs damages the connecting thread mechanism and renders them unusable, the screw 51 can be rotated until it separates from the thread groove 11. The screw 51 can then be completely pulled out, at which point the locking block 5 is separated from the locking groove 12. Force can then be applied to pull out the damaged threaded cylinder 3 or limiting cylinder 4, and selectively replace it with a new component. The new threaded cylinder 3 can then be screwed onto the threaded post 41, allowing the anchor bolt to continue to be used. Compared to the current practice of discarding anchor bolts once damaged, this reduces the cost of using them and provides a more ideal performance.
