[0002] With the development of society and technology, the equipment in various fields has been greatly improved. A detonator is a main initiating material for blasting engineering, and its function is to generate initiating energy to detonate various explosives, detonating cords, and detonating pipes. It is currently commonly used in ore rock mountains. Before using a detonator for blasting, it is generally necessary to first drill blasting holes on the surface of the ore rock mountain and measure the angles of the blasting holes through an angle measuring device to ensure that the angles of the blasting holes meet the requirements and improve the subsequent blasting effect.

[0003] After retrieval, the publication number CN217950345U, with the application date of February 16, 2022, discloses a blasting hole angle measuring device for open-pit deep-hole blasting, including a telescopic insertion rod with adjustable length. A plurality of sliding bars are vertically and annularly arranged on the upper side of the telescopic insertion rod. An installation limit sleeve with variable diameter is sleeved outside the telescopic insertion rod. A limit sliding groove adapted to the sliding bar is opened on the inner wall of the installation limit sleeve. An inner cavity is opened at the bottom end of the telescopic insertion rod. A glass baffle is installed on the bottom surface of the telescopic insertion rod below the inner cavity. A camera is installed downward in the inner cavity. A plurality of fixing nails are annularly installed on the bottom surface of the telescopic insertion rod. A top seat is installed at the top end of the telescopic insertion rod, and a measuring plate is installed on the top seat. The utility model can make the telescopic insertion rod be placed into the blasting hole more stably and quickly in the measurement of blasting holes of some open-pit deep holes with larger inclination angles and greater depths, can guide and install telescopic insertion rods with different diameters, and improves the measurement accuracy and measurement efficiency.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. When the above-mentioned blasting hole angle measuring device for open-pit deep-hole blasting is used, the length of the telescopic rod is adjusted and limited by fastening screws. This method is relatively cumbersome and time-consuming and laborious for the staff to operate, resulting in low work efficiency.

Specific embodiments

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Specific embodiment one

[0036] Please refer toFigures 1 to 6 , the utility model is a blasting hole angle measuring device for open-pit deep-hole blasting, including a telescopic sleeve 1 and an extension rod 101 slidably connected to the inner bottom end thereof. A sliding ring 104 is slidably connected to the outer side of the outer wall of the telescopic sleeve 1. The top of the outer wall of the telescopic sleeve 1 is movably connected to a rotating ring 105 through a bearing. The outer wall of the sliding ring 104 is evenly spaced with telescopic rods 4 along the circumferential direction.

[0037] Specifically, a cavity 1011 is provided at the center position of the bottom of the extension rod 101. A camera 102 is installed inside the cavity 1011. The outer wall of the telescopic sleeve 1 is evenly spaced with limiting slide bars 103 along the circumferential direction. The inner wall of the sliding ring 104 is evenly spaced with limiting slide grooves 1041 along the circumferential direction, and the limiting slide grooves 1041 are located on the outer side of the outer wall of the limiting slide bars 103. The other end of the telescopic rod 4 is installed with a placement plate 1042. A ground nail 1043 is installed at the center position inside the placement plate 1042. A display plate 1051 is installed at the rear edge of the upper surface of the rotating ring 105. A measuring plate 1052 is installed at the rear end face of the display plate 1051. A measuring mechanism 1053 is provided at the rear end face of the measuring plate 1052. An angle plate 1054 is provided on one side of the rear end face of the measuring plate 1052.

[0038] Furthermore, the extension rod 101 can slide inside the telescopic sleeve 1. The sliding ring 104 can slide with the assistance of the limiting slide bars 103 and the limiting slide grooves 1041. The measuring plate 1052, the display plate 1051, the measuring mechanism 1053 and the angle plate 1054 can rotate on the outer wall of the telescopic sleeve 1 through the rotating ring 105 and be in the vertical direction. The display plate 1051, the measuring mechanism 1053, etc. are all prior arts, so no more details will be described here. Under the action of the telescopic rod 4, the extension length of the ground nail 1043 towards the outside can be adjusted, and the applicable range is wide.

[0039] The operation process of this embodiment is as follows: Put the telescopic sleeve 1 and the extension rod 101 after the length adjustment is completed into the blasting hole, and make the bottom of the extension rod 101 contact the inner bottom end of the blasting hole. Then, with the assistance of the limit slide bar 103 and the limit chute 1041, slide and adjust the height position of the sliding ring 104, and make the bottom of the placement plate 1042 closely adhere to the ground. Then, stretch the placement plate 1042 outward according to the diameter of the blasting hole, so that the placement plate 1042 will move outward under the extension action of the telescopic rod 4, so that the positions of the placement plate 1042 and the ground nail 1043 can be adjusted according to the diameter of the blasting hole, and the application range is wide. After the telescopic sleeve 1 is placed, under the gravity of the display board 1051, the measuring board 1052, the measuring mechanism 1053 and the angle board 1054, the rotating ring 105 will rotate on the outer wall of the telescopic sleeve 1, and the display board 1051, the measuring board 1052, the measuring mechanism 1053 and the angle board 1054 will rotate to the lowest point. Then, measure the inclination angle of the blasting hole, which can improve the measurement accuracy, and is easy to operate, saving time and effort. Specific Embodiment Two

[0041] Please refer to Figure 1 、 Figure 3 and Figure 4 On the basis of Specific Embodiment One, the difference from the first embodiment is that: an adjustment component 2 is provided at the center of the top of the telescopic sleeve 1, and a limit component 3 is provided on one side of the front end of the top of the telescopic sleeve 1. The adjustment component 2 includes a front support plate 201 and a rear support plate 202 arranged directly behind it. A left rotating shaft 203 is movably installed on one side of the opposite end faces of the front support plate 201 and the rear support plate 202; the limit component 3 includes a fixed plate 301 and a limit plate 302 arranged with a gap on the outer side of its outer wall. A connecting rod 303 is fixedly connected to the center position of the inner wall of the limit plate 302, which solves the problem that when the existing blasting hole angle measuring device for open-pit deep-hole blasting is used, the length of the telescopic rod is adjusted and limited by fastening screws, and this method is more cumbersome and time-consuming for the staff to operate, resulting in low work efficiency. At the same time, the position of the fastening screw is close to the blasting hole wall and the ground, which is not convenient for the staff to operate.

[0042] Specifically, a winding roller 2031 is sleeved at the center position of the outer wall of the left rotating shaft 203, a ratchet wheel 2032 is sleeved at the front end of the outer wall of the left rotating shaft 203, a right rotating shaft 204 is installed in the bearing on one side of the front end face of the rear support plate 202, a coil spring 205 is sleeved on the outer side of the outer wall of the right rotating shaft 204, the other end of the coil spring 205 is fixed to the rear end of the outer wall of the left rotating shaft 203, a connecting rope 2033 is sleeved on the outer side of the outer wall of the winding roller 2031, the other end of the connecting rope 2033 passes through the through hole at the top of the telescopic sleeve 1 and is connected to the center position of the top of the extension rod 101, a pull ring 3021 is installed on the outer side of the outer wall of the limiting plate 302, the other end of the connecting rod 303 passes through the through hole on the outer wall of the fixing plate 301 and is connected to the clamping block 305, a spring 304 is sleeved on the outer side of the outer wall of the connecting rod 303, the spring 304 is located between the fixing plate 301 and the clamping block 305, and the bottom of the fixing plate 301 is fixed to the upper surface of the telescopic sleeve 1.

[0043] Furthermore, one ends of the winding roller 2031, the ratchet wheel 2032, and the coil spring 205 are all arranged on the outer wall of the left rotating shaft 203, so the four can move synchronously. The winding roller 2031 is connected to the top of the extension rod 101 through the connecting rope 2033, which plays a role in connecting and transmitting. The connecting rope 2033 is made of a relatively hard material, such as steel wire rope, etc., and a certain force needs to be applied when it contracts. The elastic force of the coil spring 205 can drive the connecting rope 2033 to wind up. The limiting plate 302 and the clamping block 305 are connected through the connecting rod 303, which plays a role in connecting and transmitting. Under the action of the elastic performance of the spring 304, the clamping block 305 can be driven to move.

[0044] The operation process of this embodiment is as follows: When it is necessary to adjust the extension length of the extension rod 101, a force is applied to the extension rod 101 to make it slide inside the telescopic sleeve 1 and move outward. At this time, the movement of the extension rod 101 will drive the winding roller 2031 and the left rotating shaft 203 on its inner wall to rotate through the connecting rope 2033, and wind the coil spring 205 on the right rotating shaft 204 around the outer wall of the left rotating shaft 203, so as to release the connecting rope 2033 wound on the outer wall of the winding roller 2031 and achieve the purpose of extending the extension rod 101. After the length adjustment of the extension rod 101 is completed, due to the limiting effect of the ratchet 2032 by the latch 305, the extension length of the extension rod 101 can be limited and fixed. When retracting the extension rod 101, the pull ring 3021 is pulled outward. The pull ring 3021 drives the limiting plate 302 under force. The inner wall of the limiting plate 302 is connected to the latch 305 through the connecting rod 303. Therefore, when the limiting plate 302 moves, it will drive the latch 305 to move under the action of the connecting rod 303 and compress the spring 304. At this time, the limiting effect of the latch 305 on the outer wall of the ratchet 2032 can be cancelled. At the same time, under the elastic performance of the coil spring 205, the left rotating shaft 203 is driven to rotate in the reverse direction, and then the winding roller 2031 can be driven to rotate in the reverse direction and wind the connecting rope 2033 on its outer wall, and at the same time achieve the purpose of retracting the extension rod 101 into the telescopic sleeve 1, which is convenient for the staff to quickly make corresponding adjustments according to the needs, saving time and effort and having high work efficiency.
