Description

Technical Field

[0001] This utility model relates to the field of slicing machine technology, and in particular to an anchor bolt magazine with accurate positioning and automatic clamping. Background Technology

[0002] Anchor bolt magazines are specialized support equipment used in underground engineering projects such as tunnels and mines. Anchor bolt magazines are an important component of drilling and anchoring rigs, primarily used for storing, managing, and automatically transporting anchor bolts (rod-shaped materials used to reinforce surrounding rock in support engineering). They play a crucial role in rig operations, directly impacting construction efficiency and safety.

[0003] In the existing technology, the anchor bolt magazines used on drilling and anchoring rigs are not accurately positioned when automatically changing bolts, which requires frequent correction of the anchor bolt magazine position during use. Moreover, most anchor bolt magazines on drilling and anchoring rigs achieve the anchor bolt tightening function through irregularly shaped springs or rubber plates. Anchor bolt magazines designed in these two ways have a short service life and the springs are prone to fatigue failure. In addition, irregularly shaped springs are difficult to process and have a high cost.

[0004] Therefore, those skilled in the art urgently need to develop an anchor bolt magazine with accurate positioning and automatic tightening. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anchor bolt magazine with accurate positioning and automatic tightening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anchor bolt chamber with accurate positioning and automatic clamping, comprising an anchor bolt chamber fixing seat, an anchor bolt chamber support shaft connected to one end of the anchor bolt chamber fixing seat, a rotary cylinder seat connected to the left end of the anchor bolt chamber support shaft, a rotary cylinder connected to the right side of the rotary cylinder seat away from the anchor bolt chamber support shaft, a bearing seat connected to the right end of the anchor bolt chamber support shaft, an anchor bolt chamber rotating shaft rotatably disposed between the rotary cylinder and the bearing seat, two anchor bolt chambers disposed on the anchor bolt chamber rotating shaft, a gripper mechanism disposed on the anchor bolt chamber, and a proximity switch sensor disposed on the rotary cylinder seat;

[0007] The clamping mechanism comprises multiple clamps evenly distributed in a ring. Each clamping mechanism includes a clamp, a first clamping plate, and a second clamping plate. The height of the second clamping plate is half that of the first clamping plate. A first pressure plate is connected to the top right side of the first clamping plate, and a second pressure plate is connected to the top left side of the second clamping plate. There are two clamps, which are staggered and rotatably connected to each other. A spring is provided between the first and second pressure plates on the left and right sides. The bottom of the spring is rotatably connected to the second pressure plate via a hinge. An anchor bolt is provided between the two clamps located on different anchor bolt chambers.

[0008] Preferably, the first clamping plate and the second clamping plate are placed side by side, and a through hole is provided in the middle of the first clamping plate, and a clamping claw shaft is provided in the through hole of the first clamping plate.

[0009] Preferably, a semi-circular arc plate is provided on the top left side of the first clamping plate, a limiting rod is provided above the gripper pivot, and a cover plate is provided on the outside of the gripper.

[0010] Preferably, the lower ends of the first clamping plate and the second clamping plate are clamping parts, and an arc-shaped clamping groove is provided on the right side of the lower ends of the first clamping plate and the second clamping plate, and the anchor rod is located in the arc-shaped clamping groove.

[0011] Preferably, a rod sleeve is provided on the left side of the end of the bearing housing away from the anchor bolt housing support shaft, and a fixed bushing is provided inside the rod sleeve. The rod sleeve and the fixed bushing are rotatably connected by a bearing, and the right end of the anchor bolt housing shaft extends into the fixed bushing and the two are fixedly connected.

[0012] Preferably, each anchor bolt chamber consists of two semi-circular toothed plates, which are fixedly connected by bolts. A semi-circular opening is provided at the center of the two semi-circular toothed plates, and the anchor bolt chamber shaft is located in the semi-circular opening. The anchor bolt chamber shaft is fixedly connected to the two semi-circular toothed plates by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention solves the problems of inaccurate bolt replacement position, easy failure of spring clips, high cost, unstable bolt clamping, and heavy workload of frequent manual bolt replacement in traditional bolt chambers.

[0015] This invention employs a rotary hydraulic cylinder to drive the anchor bolt chamber's rotating shaft in a smooth rotational motion. Simultaneously, a proximity switch sensor provides precise control, ensuring the rotary cylinder stops promptly at a specific automatic bolt-changing position, guaranteeing operational accuracy. The bearing housing plays a crucial role, significantly ensuring the stability of the anchor bolt chamber's rotating shaft during rotation, preventing wobbling and misalignment. The anchor bolt chamber is equipped with a cleverly designed scissor-fork gripper mechanism, capable of clamping eight anchor bolts at once, improving clamping efficiency, and providing a smooth, continuous clamping action. When the anchor bolt enters, the gripper's bottom opens, and the pressure plate approaches the compression spring; when the anchor bolt is in place, the spring returns to its original position, and the gripper closes and locks. Furthermore, disassembling and installing the semi-circular toothed plate requires only simple adjustment of the corresponding bolts, making operation convenient and efficient. Overall, it achieves the technical effects of accurate positioning and automatic clamping. Attached Figure Description

[0033] Please see Figures 1-13 This utility model provides an embodiment: an anchor bolt chamber with accurate positioning and automatic clamping, including an anchor bolt chamber fixing seat 5, the number of anchor bolt chamber fixing seats 5 is two, one end of the two anchor bolt chamber fixing seats 5 is connected to an anchor bolt chamber support shaft 4, the left end of the anchor bolt chamber support shaft 4 is connected to a rotary cylinder seat 1, the right side of the rotary cylinder seat 1 away from the anchor bolt chamber support shaft 4 is connected to a rotary cylinder 2, the right end of the anchor bolt chamber support shaft 4 is connected to a bearing seat 8, an anchor bolt chamber rotating shaft 6 is rotatably provided between the rotary cylinder 2 and the bearing seat 8, the anchor bolt chamber rotating shaft 6 is provided with two anchor bolt chambers 7, the anchor bolt chambers 7 are provided with a gripper mechanism 71, and the rotary cylinder seat 1 is provided with a proximity switch sensor 3;

[0034] The number of gripper mechanisms 71 is multiple and they are evenly distributed in a ring. Each gripper mechanism 71 includes grippers 73. Each gripper 73 includes a first clamping plate 74 and a second clamping plate 75. The height of the second clamping plate 75 is half that of the first clamping plate 74. A first pressure plate 743 is connected to the top right side of the first clamping plate 74, and a second pressure plate 751 is connected to the top left side of the second clamping plate 75. There are two grippers 73, which are placed alternately. The two grippers 73 are rotatably connected to each other. A spring 76 is provided between the first pressure plate 743 and the second pressure plate 751 on the left and right sides. The bottom of the spring 76 is rotatably connected to the second pressure plate 751 through a hinge. An anchor 9 is provided between the two grippers 73 located on different anchor chambers 7.

[0035] The bolt magazine is fixed to the double guide beam of the drill arm by the bolt magazine fixing seat 5. The bolt magazine support shaft 4 serves as the main support component. The rotary cylinder 2 is used as the power source. The rotary cylinder 2 drives the bolt magazine rotating shaft 6 to rotate. The rotary cylinder 2 stops rotating after reaching the position where automatic bolt changing is required, and then the bolt changing operation is performed. After the bolt 9 is taken away by the gripper mechanism 71, the rotary cylinder 2 starts again, rotating the bolt magazine 7 to the next position where the bolt 9 is installed, and repeating the above process.

[0036] Please see Figures 8-12 The first clamping plate 74 and the second clamping plate 75 are placed side by side. A through hole 714 is provided in the middle of the first clamping plate 74. A gripper shaft 77 is provided in the through hole 714 of the first clamping plate 74. A semi-circular arc plate 742 is provided on the top left side of the first clamping plate 74.

[0037] The two grippers 73 are connected in a scissor-fork manner. When the anchor rod 9 enters the clamping part, the bottom of the two grippers 73 opens, and at the same time, the distance between the first pressure plate 743 and the second pressure plate 751 on the left and right sides decreases, and the spring 76 is compressed. When the anchor rod 9 is fully inserted into the arc-shaped clamping groove, the spring 76 returns to its original deformation, and at the same time, the distance between the first pressure plate 743 and the second pressure plate 751 returns to normal, and the bottom opening of the two grippers 73 closes, thereby locking the anchor rod 9. The limiting rod 78 limits the rotation of the two grippers 73.

[0038] The number of gripper mechanisms 71 is eight, meaning that the gripper mechanism 71 can clamp eight anchor rods 9 at a time.

The bearing seat 8 ensures the rotational stability of the anchor bolt housing shaft 6.

[0040] Please see Figure 3 , Figure 4 and Figure 8 Each anchor chamber 7 consists of two semi-circular toothed plates 10. The two semi-circular toothed plates 10 are fixedly connected by bolts. A semi-circular opening is provided at the center of the two semi-circular toothed plates 10. The anchor chamber shaft 6 is located in the semi-circular opening and is fixedly connected to the two semi-circular toothed plates 10 by bolts. During disassembly and installation, the semi-circular toothed plates 10 can be removed and assembled simply by adjusting the corresponding bolts. The operation is simple and efficient.

[0041] Working principle of this utility model:

[0042] 1. The bolt magazine is fixed to the double guide beam of the drill arm by the bolt magazine fixing seat 5. The bolt magazine support shaft 4 serves as the main support component. The rotary cylinder 2 is used as the power source. The rotary cylinder 2 drives the bolt magazine rotating shaft 6 to rotate. The rotary cylinder 2 stops rotating after reaching the position where automatic bolt changing is required by the proximity switch sensor 3. Then the bolt changing operation is performed.

[0043] 2. When the anchor rod 9 enters the clamping part, the bottom of the two clamping claws 73 opens, and at the same time the distance between the first pressure plate 743 and the second pressure plate 751 on the left and right sides decreases, and the spring 76 is compressed.
