Description

Technical Field

[0001] This utility model relates to the field of rock blasting technology, and in particular to a borehole angle positioning bracket that adapts to the joint dip angle. Background Technology

[0002] In rock and soil blasting, the accurate positioning and measurement of borehole angles directly affects blasting efficiency, engineering safety, and resource utilization. This is especially true for rock masses with joint dip angles, where the borehole angles must be highly adapted to the joint characteristics to effectively control the blasting range, reduce over-excavation and under-excavation, and minimize disturbance to the surrounding rock mass. Currently, the industry often uses traditional tools combined with manual experience to position borehole angles for joint dip angles. This method has significant limitations, resulting in large discrepancies between the measured results and the actual values. Therefore, we propose a borehole angle positioning support adapted to joint dip angles. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a borehole angle positioning bracket that adapts to joint dip angles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A borehole angle positioning bracket adaptable to joint dip angle includes a base plate, a cylindrical block rotatably sleeved on the top of the base plate, a fixed plate fixed to the cylindrical block by a fixed rod, a lifting seat slidably sleeved on the fixed rod, a lifting mechanism for driving the lifting seat to rise and fall mounted on the cylindrical block, a fixed shaft fixed to the side of the lifting seat, a collar rotatably sleeved on the fixed shaft, a counterweight fixed to the collar by a suspension rope, a cap rotatably sleeved at one end of the fixed shaft, a sliding hole provided on the cap, a positioning rod slidably sleeved in the sliding hole, and an angle scale ring fixed on the lifting seat, the angle scale ring being coaxial with the fixed shaft.

[0006] Preferably, rollers are installed at all four corners of the bottom of the base plate, and brake pads are provided on the rollers.

[0007] Preferably, the top of the base plate is threaded with a first locking screw for securing the cylindrical block.

[0008] Preferably, the lifting mechanism includes a lead screw and a motor. The motor is installed at the bottom of the fixed plate, and the output shaft of the motor is connected to the lead screw. The lead screw is threaded into the lifting seat, and one end of the lead screw is rotatably sleeved in the cylindrical block.

[0009] Preferably, a battery box for supplying power to the motor is installed at the bottom of the fixing plate.

[0010] Preferably, one end of the positioning rod is fixed with a handle, and a second locking screw for locking the positioning rod is threaded onto the shaft cap.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the roller is easily moved to a designated position. Once at the designated position, the roller is locked in place by a brake pad. The horizontal orientation of the positioning rod can be adjusted by rotating the cylindrical block. The height of the positioning rod can be adjusted by raising and lowering the lifting seat through the lifting mechanism. The counterweight pulls the hoisting rope, ensuring that the hoisting rope is always in a vertical position. This facilitates the measurement of the angle between the hoisting rope and the positioning rod, thereby measuring the borehole angle. The positioning rod is adjusted by the handle. By rotating the positioning rod, it is inserted into the borehole, facilitating the positioning of the borehole inclination angle and enabling accurate measurement of the borehole angle. The angle between the positioning rod and the hoisting rope can be determined through the angle scale ring. The first locking screw is used to lock the cylindrical block, facilitating the determination of the horizontal orientation of the positioning rod. The second locking screw is used to lock the positioning rod, facilitating the determination of the vertical inclination angle of the positioning rod. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4A borehole angle positioning bracket adaptable to joint dip angle includes a base plate 1. A cylindrical block 3 is rotatably sleeved on the top of the base plate 1. By rotating the cylindrical block 3, the horizontal orientation of the positioning rod 10 can be adjusted. A fixing plate 12 is fixed on the cylindrical block 3 by a fixing rod 5. A lifting seat 9 is slidably sleeved on the fixing rod 5. A lifting mechanism for raising and lowering the lifting seat 9 is installed on the cylindrical block 3. The lifting mechanism raises and lowers the lifting seat 9, adjusting the height of the positioning rod 10. A fixing shaft 20 is fixed on the side of the lifting seat 9. A collar 16 is rotatably sleeved on the fixing shaft 20. A counterweight 8 is fixed on the collar 16 by a suspension rope 7. The counterweight 8 pulls the suspension rope 7, keeping the suspension rope 7 in a vertical position. This facilitates the measurement of the angle between the suspension rope 7 and the positioning rod 10, thereby measuring the borehole angle. A shaft cap 15 is rotatably sleeved on one end of the fixing shaft 20. A sliding hole 19 is opened on the shaft cap 15, and the positioning rod 10 is slidably sleeved in the sliding hole 19. By rotating the shaft cap 10, the positioning rod 10 can be adjusted. The positioning rod 10 is inserted into the blast hole to facilitate the positioning of the blast hole inclination angle and to accurately measure the blast hole angle. An angle scale ring 13 is fixed on the lifting seat 9. The angle scale ring 13 is coaxial with the fixed shaft 20. The angle between the positioning rod 10 and the lifting rope 7 can be known through the angle scale ring 13. Rollers 2 are installed at the four corners of the bottom of the base plate 1. The rollers 2 are equipped with brake pads to facilitate the overall movement to the designated position. The top of the base plate 1 is threaded with a first locking screw 4 for locking the cylindrical block 3. The first locking screw 4 is used to lock the cylindrical block 3 and to determine the horizontal orientation of the positioning rod 10. A handle 11 is fixed to one end of the positioning rod 10. The positioning rod 10 is adjusted by the handle 11. A second locking screw 14 is threaded on the shaft cap 15 for locking the positioning rod 10. The second locking screw 14 is used to lock the positioning rod 10 and to determine the inclination angle of the positioning rod 10 in the vertical direction.

[0020] Reference Figure 1 , Figure 4 The lifting mechanism includes a lead screw 6 and a motor 18. The motor 18 is installed at the bottom of the fixed plate 12. The output shaft of the motor 18 is connected to the lead screw 6. The lead screw 6 is threaded into the lifting seat 9. One end of the lead screw 6 is rotatably sleeved in the cylindrical block 3. The motor 18 drives the lead screw 6 to rotate. The lead screw 6 can drive the lifting seat 9 to rise and fall through the threaded transmission between it and the lifting seat 9. The battery box 17 supplies power to the motor 18. The bottom of the fixed plate 12 is equipped with a battery box 17 for supplying power to the motor 18.

[0021] Working principle: During use, roller 2 can be easily moved to the designated position. After reaching the designated position, roller 2 is locked by brake pads. By rotating cylindrical block 3, the horizontal orientation of positioning rod 10 can be adjusted. The lifting mechanism drives the lifting seat 9 to rise and fall, which can adjust the height of positioning rod 10. Counterweight block 8 pulls the hoisting rope 7, so that the hoisting rope 7 is always in a vertical position. This makes it easy to measure the angle between the hoisting rope 7 and positioning rod 10, thereby measuring the blast hole angle. The positioning rod 10 is adjusted by handle 11. By rotating positioning rod 10, positioning rod 10 is inserted into the blast hole, which makes it easy to position the blast hole inclination angle and accurately measure the blast hole angle. The angle between positioning rod 10 and hoisting rope 7 can be known by angle scale ring 13. The first locking screw 4 is used to lock cylindrical block 3 to determine the horizontal orientation of positioning rod 10. The second locking screw 14 is used to lock positioning rod 10 to determine the vertical inclination angle of positioning rod 10.

[0022] The operating principle of the lifting mechanism is as follows: the motor 18 drives the lead screw 6 to rotate, and the lead screw 6 can drive the lifting seat 9 to rise and fall through the threaded transmission between it and the lifting seat 9. The battery box 17 supplies power to the motor 18.
