Technical Field

[0001] The utility model relates to the technical field of blasting construction, in particular to a blasthole angle measuring device. Background Art

[0002] During open-pit blasting operations, the quality of the blasthole is a key factor affecting the blasting effect. Based on the free surface angle of the blasting rock mass's movement direction, the main methods for drilling the blastholes are inclined drilling and vertical drilling from a vertical perspective. To ensure uniform spacing between adjacent blastholes and prevent crossover or perforation, the current method for measuring blasthole angles is usually visual inspection or a rough estimate of the angle between the drill rod and the ground. There is also a lack of effective tools for measuring the angle between adjacent blastholes. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the purpose of the present invention is to provide a blasthole angle measuring device to measure the angle of the blasthole more conveniently.

A baffle 202 is provided on the support block 2. The baffle 202 limits the support plate 21 to rotate only along a certain angle. When the lower end of the support tube 1 extends into the blast hole, the support plate 21 is rotated so that the support plate 21 is supported on the outside of the blast hole to prevent the measuring device from falling into the blast hole.

[0032] like Figure 1 、 2 As shown in , 3, 4, and 10, a driving ring 3 is rotatably provided at one end of the support tube 1, a rack 31 is provided inside the driving ring 3, and a top cover 4 is also provided at one end of the driving ring 3. The driving ring 3 and the top cover 4 are rotatably connected, and a plurality of limiting rods 41 are provided inside the top cover 4. The limiting rod 41 is C-shaped, one end of the limiting rod 41 is connected to the top cover 4, and the other end is connected to the support tube 1. The driving ring 3 is set at the bending position of the limiting rod 41 and can be rotated at the bending position of the limiting rod 41. The limiting rod 41 fixes the top cover 4 and the support tube 1 together to prevent one of them from rotating when the driving ring 3 rotates. This design does not affect the rotation of the driving ring 3. A measuring ruler 42 is provided on the top cover 4. The measuring ruler 42 is an angle measuring instrument in the prior art. The measuring ruler 42 is set on the side circumferential surface of the top cover 4. The measuring device is inserted into the blast hole, and the numerical change of the measuring ruler 42 is observed. The measuring ruler 42 can detect the angle of the blast hole.

[0033] like Figure 1 、 2As shown in Figures 7, 8, 9 and 10, at least two groups of drive components A are provided in the support cylinder 1, and a plurality of support holes 101 are provided on the surface of the support cylinder 1. The drive component A includes gear I7, gear II5 and connecting rod 6. A support column 52 is provided inside the gear II5, and the support column 52 is connected to the inside of the support cylinder 1.

The two ends of the connecting rod 62 are respectively connected to the connecting rod 6 of the two groups of driving assemblies A. One group of driving assemblies A rotates internally, and the other group rotates accordingly. Although the two groups of gears Ⅰ7 can also drive the arc-shaped block 61 to move, the design of the connecting rod 62 not only increases the overall stability, but also makes the transmission efficiency higher.

[0034] Working principle: Insert the bottom of the measuring device into the blast hole, open the support plate 21, make the support plate 21 against the outside of the blast hole to prevent the measuring device from falling into the blast hole, rotate the drive ring 3, the drive ring 3 rotates to drive the rack 31 and gear III8 to move, the gear III8 rotates through the connecting column 71 to drive the two gears I7 below to rotate synchronously, the gear I7 rotates while driving the gear II5 to rotate, the arc groove 51 on the gear II5 rotates, pushing the connecting rod 6 to slide out of the support hole 101, and making the arc block 61 abut against the inner wall of the blast hole, observe the data of the measuring ruler 42, and obtain the angle information of the blast hole. When removing the measuring device, just reverse the drive ring 3 so that the arc block 61 gradually fits the support tube 1, pull the measuring device out of the blast hole, and retract the support plate 21.
