Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of auxiliary device, specifically is explosive blasting auxiliary device. BACKGROUND

[0002] Explosive blasting technology has a wide range of applications in engineering practice, especially in mountain blasting operations. Through explosive blasting, large-volume rocks or solid materials can be effectively fragmented into small particles, thereby facilitating subsequent transportation and processing. During explosive blasting, detonation is a typical energy release form when the propagation speed of the chemical reaction zone inside the explosive exceeds the sound speed in the explosive. However, the enormous energy generated by the explosion of explosives not only serves to break the target object, but also forms a region of sudden pressure drop around the explosion source. This low-pressure region causes gas to rapidly diffuse outward, thereby carrying the fragments and particles produced by the explosion to splash in all directions, posing a potential safety threat to the surrounding environment and personnel.

[0003] To reduce this risk, some solutions have been proposed in the industry. For example, patent number 202122238881.9 discloses an explosive blasting auxiliary device, which includes multiple insertion rods, a connecting ring is slidably arranged on the insertion rod, and the connecting ring is connected to the protective net through a buckle. The protective net is also provided with a buckle that cooperates with the buckle, and an elastic element is provided between the connecting ring and the top plate of the insertion rod. In use, after the explosive is buried, the insertion rod is inserted into the surrounding soil, and the protective net is mounted in place through the buckle and the buckle. In this way, when the explosive explodes, the protective net can intercept the splashing fragments, achieving the first buffering, while the elastic element provides the second buffering, thereby simplifying the overall structure and reducing the safety risk.

[0004] However, the above-mentioned scheme still has some deficiencies in actual application. In particular, there is no effective limiting mechanism on the insertion rod, which leads to the fact that the insertion rod is easily pulled out of the soil under the action of the huge impact force generated by the explosion of the explosive. Once the insertion rod is pulled out, the stability of the entire auxiliary device will be seriously affected, not only cannot effectively intercept the splashing fragments, but also may cause greater safety hazards to the surrounding due to structural failure. Therefore, it is necessary to improve the above-mentioned scheme to enhance its stability and safety in actual application. UTILITY MODEL CONTENTS

[0023] The outer surface of the nail inserting barrel 1 is fixedly connected with a first circular plate 3, and the upper surface of the first circular plate 3 is mounted with dampers 4.

[0024] The top end of the damper 4 is fixedly connected with a second circular plate 6, and the bottom surface of the second circular plate 6 is fixedly connected with springs 5.

[0025] The bottom end of the spring 5 is fixedly connected with the first circular plate 3.

[0026] The inside of the second circular plate 6 is provided with a through hole 7.

[0027] The upper surface of the second circular plate 6 is rotatably connected with a rotating head 8, and the rotating head 8 is mounted with a circular ring 9.

[0028] The dampers 4 and the springs 5 are both provided with four, and are both arranged between the first circular plate 3 and the second circular plate 6.

[0029] The position where the through hole 7 is provided in the second circular plate 6 is located directly above the rotating rod 201, and is used to rotate the rotating rod 201 through an external tool. Embodiment one

[0030] Referring to Figs. 1-4 , the present embodiment provides an explosive blasting auxiliary device, which has the structure as described above, including a nail inserting barrel 1, a fixing mechanism 2, a first circular plate 3, dampers 4, springs 5, a second circular plate 6, a through hole 7, a rotating head 8 and a circular ring 9. The present embodiment focuses on the detailed implementation of the fixing mechanism 2.

[0031] Specifically, the fixing mechanism 2 includes a rotating rod 201, a circular plate 202, a first bevel gear 203, a second bevel gear 204, a lead screw 205, a fixed square nail barrel 206, a square hole 207, a first fixed plate 208 and a second fixed plate 209. In use, by rotating the rotating rod 201, the first bevel gear 203 is driven to rotate, and in turn drives the second bevel gear 204 meshing therewith to rotate. The rotation of the second bevel gear 204 is further transmitted to the lead screw 205, and since the lead screw 205 is threadedly connected with the fixed square nail barrel 206, the rotation of the lead screw 205 drives the fixed square nail barrel 206 to move leftward on the lead screw 205 until it extends out of the square hole 207 and is inserted into the soil, achieving stable fixation.

[0032] In this embodiment, the meshing angle of the first bevel gear 203 and the second bevel gear 204 and the thread matching precision between the lead screw 205 and the fixed square nail barrel 206 are particularly optimized, ensuring that the fixing mechanism 2 can still remain stable under the huge impact force generated by the explosion of the explosive, effectively preventing the nail inserting barrel 1 from being pulled out. Embodiment two

[0033] Referring to Figs. 1-4The embodiment provides another explosive blasting auxiliary device, which has a similar overall structure to the foregoing embodiments, but the embodiment is particularly concerned with the detailed implementation of the buffering and rotating mechanism.

[0034] Specifically, the device comprises a spike insertion barrel 1, a first circular plate 3 fixed to the outer surface of the spike insertion barrel 1, a damper 4 and a spring 5 mounted on the first circular plate 3, and a second circular plate 6 connected with the damper 4 and the spring 5. The second circular plate 6 is further provided with a through hole 7, a rotating head 8 and a circular ring 9.

[0035] In use, the impact force generated by the explosion of the explosive first acts on the second circular plate 6, at which time the damper 4 and the spring 5 jointly serve as a buffer to absorb and disperse part of the impact force, thereby improving the stability of the entire device.

[0036] In this embodiment, the material, specification and arrangement of the damper 4 and the spring 5 are optimized to ensure that sufficient buffering effect can be provided when the explosive explodes. At the same time, the rotating connection structure of the rotating head 8 and the circular ring 9 is also precisely designed to enable flexible rotation when subjected to the impact force, thereby improving the impact resistance of the device.

[0037] Working principle: when the device is used, the spike insertion barrel 1 is first inserted into the soil, then an external tool is inserted into the top end of the rotating rod 201 through the through hole 7, and the external tool is rotated. The rotation of the rotating rod 201 drives the first bevel gear 203 to rotate, and since the first bevel gear 203 is engaged with the second bevel gear 204, the rotation of the first bevel gear 203 drives the second bevel gear 204 to rotate. The rotation of the second bevel gear 204 further drives the lead screw 205 to rotate. Since the lead screw 205 is in threaded connection with the fixed square nail barrel 206, the rotation of the lead screw 205 drives the fixed square nail barrel 206 to move leftwards on the lead screw 205. When the fixed square nail barrel 206 moves leftwards, it gradually extends out of the square hole 207 and is inserted into the soil, thereby fixing the spike insertion barrel 1 and preventing it from being pulled out due to the impact force generated by the explosion of the explosive. During the explosion of the explosive, the impact force first acts on the second circular plate 6. At this time, the damper 4 and the spring 5 serve as a buffer to absorb part of the impact force, thereby protecting the entire device from damage and improving the stability of the device.

[0038] The above merely describes the preferred embodiments of the device and is not intended to limit the device, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the device shall be included in the protection scope of the device.
