Description

Technical Field

[0001] This invention belongs to the field of anchor bolt equipment technology, specifically relating to a high-strength anchor bolt and its processing equipment. Background Technology

[0002] Rock bolts are the most basic component of roadway support in modern coal mines. They reinforce the surrounding rock of the roadway, allowing the surrounding rock to support itself. Rock bolts are not only used in mines, but also in engineering technology for the main reinforcement of slopes, tunnels, and dams. Equal strength rock bolts are a type of rock bolt, and the entire rock bolt is threaded after processing and production.

The grout is discharged from the discharge port 621 through the tail end fixing block 63, anchor bolt body 61, and anchor bolt drill bit 62. The drill hole is filled and then stopped. The connection between the grouting machine pipe head and the tail connector 633 is disconnected and the tail connector 633 is sealed.

[0049] The processing equipment is mainly used to slot and tap the first threaded hole 613 and the first mounting groove 614 on the anchor body 61. The working principle is as follows:

[0050] In use, the blank anchor rod body 61 is placed between the clamps 241, the pneumatic gripper 24 clamps the blank anchor rod body 61, the first electric slide 21 feeds one end of the blank anchor rod body 61 into the machining groove 541, the second cylinder 56 pushes the limiting post 561 into the through hole 611, and the limiting strip 562 is engaged in the slot 612, thereby fixing the blank anchor rod body 61. The drill bit 36 ​​advances through the first through hole 542 to open and tap the first threaded hole 613, and the air blowing pipe 55 blows air. After the hole 613 is processed, the limiting post 561 retracts and withdraws. The pneumatic gripper 24 drives the blank anchor rod body 61 to descend between the first clamping block 51 and the second clamping block 52. The first clamping block 51 and the second clamping block 52 fix the blank anchor rod body 61. The reamer 41 advances and passes through the second through hole 543 to make the first mounting groove 614 slotted. After the processing is completed, the blank anchor rod body 61 retracts. Then, the cylinder 22 is rotated to drive the blank anchor rod body 61 to rotate 180°. The above operation is repeated to process the other end.
