Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and particularly relates to a safe blasting and collapse prevention device. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. In civil engineering, in order to better study rocks and change terrain, blasting devices are generally used to blast rocks, destroy them through explosions, and in order to protect surrounding workers, it is generally necessary to apply safety anti-collapse devices during the blasting process to reduce safety hazards.

[0003] After searching, the announcement number CN220507867U, application date 2023.06.29 discloses a safe blasting and collapse prevention device, including a base, a buffer device is provided on the upper part of the base, the buffer device includes a buffer chamber, a buffer plate is provided in the buffer chamber, a buffer spring is fixedly connected to the upper part of the buffer plate, the buffer spring is a multi-stage spring, and the buffer spring is fixedly connected to the inner top wall of the buffer chamber. During the rock burst process, the kinetic energy of flying rocks is absorbed by the buffer plate and the buffer spring. The buffer spring is a multi-stage spring, so it can absorb the kinetic energy of flying rocks of various sizes and various speeds during the buffering process. There is no need to manually replace the spring according to the flying rocks in different scenes, which improves the efficiency of rock burst work. At the same time, it avoids the situation where the manual judgment may be inaccurate when manually replacing the spring according to the flying rocks in different scenes, resulting in the failure to match the correct spring and causing an accident. The structure is simple and the operation is safe and convenient.

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

[0005] 1. The above-mentioned safety blasting and collapse prevention device directly places the base outside the blasting hole when in use. However, when the blasting hole is not in a vertical relationship with the outer plane, the airflow will not be able to play an effective buffering role after rushing out, affecting the blasting protection effect;

However, this method cannot adjust the number of buffer springs, which will affect the absorbed kinetic energy and cannot play an effective protective role according to the actual situation. The scope of application is small. To this end, we provide a safety blasting and anti-collapse device to solve the above-mentioned problems. Utility Model Content

[0036] Specifically, a mounting plate 101 is fixedly connected to one side of the outer wall of the base 1, a rotating seat 1031 is fixedly connected to the inner side of the bottom of the turntable 103, the bottom of the rotating seat 1031 is installed on the outer side of the top of the fixing ring 102, a gear ring 1032 is sleeved on the outer bottom of the outer wall of the rotating seat 1031, a left plate 104 is fixedly connected to the edge of the other side of the upper surface of the turntable 103, a left rotating shaft 1041 is rotatably connected to the upper inner wall of the left plate 104, a right rotating shaft 1051 is rotatably connected to the inner bearing above the right plate 105, the outer end of the right rotating shaft 1051 passes through the bearing inside the right plate 105 and is connected to the gear plate 1052, and the left rotating shaft 1041 is fixedly connected to the inner wall of the left plate 104. 041 and the inner ends of the right rotating shaft 1051 are respectively fixed to the bottom of the outer walls on both sides of the adjusting frame 106, and connecting cloth 1061 is arranged between the upper surface of the turntable 103 and the bottom of the adjusting frame 106, as well as the top of the outer wall of the adjusting frame 106 and the bottom of the outer wall of the top cover 107. A buffer mechanism 108 is arranged at the inner top of the top cover 107. A pull ring 2021 is fixedly connected to the center position of the outer wall of the limiting plate 202. The other end of the connecting rod 203 passes through the through hole on the outer wall of the support plate 201 and is connected with the block 205. A reset spring 204 is sleeved on the outer side of the outer wall of the connecting rod 203, and the reset spring 204 is located between the support plate 201 and the block 205.

[0037] Furthermore, the base 1 can be fixed by the mounting plate 101, and half of its area can be fixed inside the blasting area to improve the stability of the base 1. The angle of the turntable 103 can be adjusted under the action of the rotating seat 1031 and the fixing ring 102. The left plate 104 and the right plate 105 are of the same shape, size, etc. When subjected to force, the adjustment frame 106 will rotate with the left rotation axis 1041 and the right rotation axis 1051 as the center of the circle, and drive the toothed disc 1052 to rotate. The connecting cloth 1061 plays a role of shielding and extending. The buffer mechanism 108 is a prior art, so it will not be described in detail here.

At this time, the limiting effect between the block 205 and the gears on the outer wall of the adjacent gear ring 1032 and the gear disk 1052 can be cancelled. Then, the angle of the upper adjustment frame 106 and the top cover 107 can be adjusted under the action of the fixed ring 102 and the rotating seat 1031. At the same time, the angle of the adjustment frame 106 and the top cover 107 can be adjusted with the left rotating shaft 1041 and the right rotating shaft 1051 as the center of the circle. Then, the angle of the adjustment frame 106 and the top cover 107 can be adjusted according to the angle of the central axis of the blasting borehole, so that the axes of the three are on the same axis, thereby improving the protection effect of subsequent blasting. Specific embodiment 2

[0040] See also Figure 4 , 6 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a protective component 3 is provided, the protective component 3 includes a connecting rod 301 and a bottom plate 304 installed at the bottom end of the fixing plate 302 through a through hole on the outer wall of the fixing plate 302, and a buffer spring 303 is sleeved on the outer side of the outer wall of the connecting rod 301, which solves the problem that the existing safety blasting and collapse prevention device plays a protective role against gravel generated during the blasting process through the buffer device when in use, while this method cannot adjust the number of buffer springs, which will affect the absorbed kinetic energy, cannot play an effective protective role according to actual conditions, and has a small scope of application.

[0041] Specifically, the top end of the connecting rod 301 is fixed to the bottom of the top cover 107 , the buffer spring 303 is located between the fixing plate 302 and the bottom plate 304 , and the outer wall of the fixing plate 302 is fixed to the outer side of the inner wall of the adjusting groove 1062 .

[0042] Furthermore, the top cover 107 and the bottom plate 304 are connected by the connecting rod 301 to play a role of connecting transmission, and can play a role of buffer protection under the elastic performance of the buffer spring 303.

[0043] The operation process of this embodiment is as follows: during the blasting process, the generated airflow will rush into the inside of the adjustment frame 106 and the top cover 107 through the through hole on the base 1, and play a buffering and protective role under the buffering action of the buffer mechanism 108 inside the top cover 107, and the top cover 107 will move outward when subjected to force, and drive the connecting rod 301 to move, and a bottom plate 304 is installed at the inner end of the connecting rod 301, so when the connecting rod 301 moves, it will drive the bottom plate 304 to move and squeeze the buffer spring 303, and under the action of the elastic performance of the buffer spring 303, part of the force can be absorbed to achieve multi-level buffering, which further plays a protective role.
