Description

Technical Field

[0001] This utility model relates to the field of hydraulic anchor drilling rig technology, and specifically to a hydraulic anchor drilling rig limiting device. Background Technology

[0002] Anchor bolt drilling rigs are mainly used for drilling operations in coal mine roadway anchor bolt support. In some places, anchor bolt drilling rigs are also called anchoring drilling rigs. They are used to fix the support structure of surrounding rock and roof. At present, they are also widely used in the construction field. They have outstanding advantages in improving support effect, reducing support cost and reducing labor intensity.

[0003] However, existing hydraulic anchor drilling rigs rely on manual measurement of the anchor insertion depth after the machine is stopped, which is cumbersome and inefficient. Furthermore, the manual measurement of the anchor insertion depth prevents real-time measurement, potentially leading to depths exceeding the required depth and hindering widespread adoption.

[0004] To address this problem, this application provides a hydraulic anchor drilling rig limiting device. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting device for a hydraulic anchor drilling rig, in order to solve the problems mentioned in the background art, such as the fact that the insertion depth of the hydraulic anchor drilling rig is mostly measured manually by the operator after the machine is stopped, which makes the operation more troublesome, the work efficiency lower, and the insertion depth cannot be obtained in real time, which may exceed the required depth and result in poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A hydraulic anchor drilling rig limiting device includes a connecting assembly, an actuating assembly, and a limiting assembly. The connecting assembly includes a connecting plate and a second fixing ring, the second fixing ring being fixedly connected to the top of the connecting plate. The actuating assembly is disposed outside the connecting assembly and includes a motor and a transmission screw. The motor is fixedly installed outside the first fixing ring, and one end of the transmission screw is rotatably installed inside the second fixing ring. The limiting assembly is disposed inside the connecting assembly and includes a connecting shaft and an angle sensor, the angle sensor being fixedly installed outside the connecting shaft.

[0008] A further improvement of this utility model is that: a first fixing ring is fixedly connected to the top of the connecting plate, a connecting hole is opened at the bottom of the connecting plate, and a connecting rod is fixedly installed on one side of the first fixing ring.

[0009] A further improvement of this utility model is that: the other end of the connecting rod is fixedly installed on one side of the second fixing ring, and both the first fixing ring and the second fixing ring have mounting holes inside, and a first gear is fixedly installed on one end of the motor.

[0010] A further improvement of the present invention is that: the first gear is externally meshed with a gear ring, the gear ring is externally meshed with a second gear, and the second gear is fixedly installed on the outside of the transmission screw.

[0011] A further improvement of this utility model is that: the other end of the transmission screw is rotatably installed inside the first fixed ring, a retaining ring is fixedly installed on the outside of the transmission screw, a movable ring is threadedly connected to the outside of the transmission screw, and a movable block is movably connected inside the movable ring.

[0012] A further improvement of this utility model is that the movable block is movably installed inside the first fixed ring and the second fixed ring, and an arc-shaped pad is fixedly installed inside the movable block.

[0013] A further improvement of this utility model is that: a roller is fixedly installed on the outside of the connecting shaft, the connecting shaft is rotatably installed inside the first fixed ring and the second fixed ring, the angle sensor is fixedly installed inside the first fixed ring, and the angle sensor is electrically connected to the motor.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a hydraulic anchor bolt drilling rig limiting device. Under the combined action of rollers, connecting shafts and angle sensors, when the anchor bolt is introduced, its outer wall contacts the rollers, causing the rollers and connecting shafts to rotate. The angle sensor measures the number of rotations of the connecting shaft, thereby determining the insertion depth of the anchor bolt. This eliminates the need for workers to stop the machine for manual measurement, improving work efficiency.

[0016] 2. This utility model provides a hydraulic anchor drilling rig limiting device. Under the combined action of a motor, an angle sensor, and an arc-shaped pad, the angle sensor detects the insertion depth of the anchor. When the insertion depth reaches the target, the motor is driven to press the movable ring down onto the movable block, causing the arc-shaped pad to provide a large frictional force to the anchor, thus stopping the anchor and preventing the insertion depth from exceeding the required depth.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a hydraulic anchor drilling rig limiting device, including a connecting component 1, an execution component 2, and a limiting component 3. The connecting component 1 includes a connecting plate 10 and a second fixing ring 12. The second fixing ring 12 is fixedly connected to the top of the connecting plate 10. A first fixing ring 11 is fixedly connected to the top of the connecting plate 10. A connecting hole 13 is provided at the bottom of the connecting plate 10. The device is connected to the drilling rig through the connecting hole 13. A connecting rod 14 is fixedly installed on one side of the first fixing ring 11. The other end of the connecting rod 14 is fixedly installed on one side of the second fixing ring 12. Mounting holes 15 are provided inside the first fixing ring 11 and the second fixing ring 12. The anchor rod passes through the interior of the first fixing ring 11 and the second fixing ring 12 through the mounting holes 15.

[0025] like Figure 2-4As shown, the actuating component 2 is disposed outside the connecting component 1. The actuating component 2 includes a motor 20 and a transmission screw 24. The motor 20 is fixedly installed outside the first fixed ring 11. One end of the transmission screw 24 is rotatably installed inside the second fixed ring 12. A first gear 21 is fixedly installed at one end of the motor 20. A gear ring 22 is meshed with the outside of the first gear 21. A second gear 23 is meshed with the outside of the gear ring 22. The second gear 23 is fixedly installed outside the transmission screw 24. The other end of the transmission screw 24 is rotatably installed inside the first fixed ring 11. A retaining ring 25 is fixedly installed on the outside of the moving lead screw 24. When the angle sensor 35 detects that the anchor rod has reached the required insertion depth, it drives the motor 20. The motor 20 drives the first gear 21 to rotate, and the first gear 21 drives the gear ring 22 to rotate. The gear ring 22 drives the various second gears 23 on its outside to rotate, which in turn drives the transmission lead screw 24 inside the second gear 23 to rotate and move the movable ring 30. The movable ring 30 presses down on the movable block 31 and the arc-shaped pad 32, so that the arc-shaped pad 32 provides a large frictional force to the anchor rod, causing the anchor rod to stop moving and preventing the insertion depth from exceeding the required depth.

[0026] like Figure 2-5 As shown, the limiting component 3 is located inside the connecting component 1. The limiting component 3 includes a connecting shaft 34 and an angle sensor 35. The angle sensor 35 is fixedly installed on the outside of the connecting shaft 34. The external thread of the transmission screw 24 is connected to a movable ring 30. The inside of the movable ring 30 is movably connected to a movable block 31. The movable block 31 is movably installed inside the first fixed ring 11 and the second fixed ring 12. An arc-shaped pad 32 is fixedly installed inside the movable block 31. A roller 33 is fixedly installed on the outside of the connecting shaft 34. The connecting shaft 34 is rotatably installed inside the first fixed ring 11 and the second fixed ring 12. The angle sensor 35 is fixedly installed inside the first fixed ring 11. The angle sensor 35 is electrically connected to the motor 20. When the anchor rod is introduced, its outer wall contacts the roller 33, causing the roller 33 and the connecting shaft 34 to rotate. The angle sensor 35 measures the number of rotations of the connecting shaft 34, thereby determining the insertion depth of the anchor rod. This eliminates the need for manual measurement by the operator, improving work efficiency.

[0027] The working principle of the hydraulic anchor drilling rig limit device will be explained in detail below.

[0028] like Figure 1-5As shown, when using the hydraulic anchor drilling rig limiting device, the device is connected to the drilling rig through the connecting hole 13. The anchor rod is then passed through the mounting hole 15 inside the first fixing ring 11 and the second fixing ring 12. When the anchor rod is introduced, its outer wall contacts the roller 33, causing the roller 33 and the connecting shaft 34 to rotate. The number of rotations of the connecting shaft 34 is measured by the angle sensor 35, thereby determining the insertion depth of the anchor rod. This eliminates the need for manual measurement by the operator, improving work efficiency. When the angle sensor 35 detects that the insertion depth of the anchor rod meets the standard, the motor 20 is driven. The motor 20 drives the first gear 21 to rotate, which in turn drives the gear ring 22 to rotate. This causes the gear ring 22 to drive the various second gears 23 outside it to rotate, causing the transmission screw 24 inside the second gear 23 to rotate and move the movable ring 30. This causes the movable ring 30 to press down on the movable block 31 and the arc-shaped pad 32, allowing the arc-shaped pad 32 to provide a large frictional force to the anchor rod, stopping its movement and preventing the insertion depth from exceeding the required depth.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
