Description

Technical Field

[0001] This utility model relates to the field of blasting protection, specifically a protective device for mine blasting. Background Technology

[0002] A mine refers to an independent production and operation unit that extracts ore within a certain mining boundary. A mine mainly includes one or more mining workshops (or pitheads, mine shafts, and open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants).

[0003] With the rapid development of mines, the frequency of mine blasting is increasing, which in turn raises the requirements for rockfall protection during mine blasting. Currently, the protection method for rockfalls is to erect a protective plate, which is easily broken. This not only has a low safety factor but also threatens the personal safety of workers. Therefore, we provide a protective device for mine blasting. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a protective device for mine blasting, including a baffle 1, with a connecting pad 2 installed on the outer surface of the baffle 1. The baffle 1 can provide a certain degree of protection for the crushed stone, thereby ensuring the personal safety of the workers. At the same time, the connecting pad 2 is made of rubber, which can buffer the impact of the crushed stone, thereby reducing the impact force on the baffle 1.

[0025] A sliding rod 3 is provided behind the baffle 1. A shock-absorbing assembly 4 is installed between the baffle 1 and the sliding rod 3. The shock-absorbing assembly 4 includes two connecting blocks 401 and two moving plates 402. The two connecting blocks 401 are fixedly connected to the outer surface of the baffle 1. The two moving plates 402 are slidably connected to the outer surface of the sliding rod 3. A compression spring 403 is installed between the moving plate 402 and the connecting block 401. The two compression springs 403 are sleeved on the outer surface of the sliding rod 3. The shock-absorbing assembly 4 also includes two hinge frames 404. The two hinge frames 404 are installed on the back of the baffle 1. A hinge rod 405 is hinged between the hinge frame 404 and the moving plate 402. Through the sliding connection between the moving plate 402 and the sliding rod 3, when the baffle 1 moves, the compression spring 403 will be compressed, and the hinge rod 405 will tilt at a certain angle, thereby facilitating the subsequent shock absorption of the baffle 1 and ensuring the normal protection of the personnel by the device.

[0026] The shock absorption assembly 4 also includes a fixing block 406, which is fixedly connected to the outer surface of the slide rod 3. Four connecting rods 407 are installed on the outer surface of the fixing block 406. Long rods 408 are slidably connected to the outer surfaces of the four connecting rods 407. A shock absorption spring 409 is installed between the connecting rods 407 and the baffle 1. One end of the long rod 408 is fixedly connected to the back of the baffle 1.

[0027] Through the sliding connection between the connecting rod 407 and the long rod 408, and the fixed connection between the long rod 408 and the baffle 1, and finally through the shock-absorbing spring 409, when the baffle 1 is displaced, the shock-absorbing spring 409 can buffer the displaced baffle 1 to a certain extent. At the same time, the slidingly connected long rod 408 can guide the movement of the baffle 1 to a certain extent, which can ensure the normal shock absorption effect of the shock-absorbing component 4 on the baffle 1.

[0028] The shock absorption assembly 4 also includes two limiting blocks 411. Both limiting blocks 411 are fixedly connected to the outer surface of the slide rod 3, and a damper 410 is installed between the limiting block 411 and the connecting block 401. The damper 410 can reduce the impact of the baffle 1, thereby ensuring the normal use of the device in the future.

[0029] A support assembly 5 is installed on the outer surface of the slide rod 3. The support assembly 5 includes two mounting cylinders 501. Both mounting cylinders 501 are bolted to both ends of the slide rod 3. The mounting cylinders 501 installed by bolts can be disassembled, thereby disassembling the device, which is convenient for subsequent personnel to carry and improves the practicality of the device.

[0030] Both mounting cylinders 501 are equipped with support rods 502 on their outer surfaces, and the bottom end of the support rods 502 is fixedly connected with a pointed cone 503. The pointed cone 503 makes it easy for workers to insert it into the ground, thereby achieving the limiting and fixing of the device and ensuring the subsequent protective effect.

[0031] The support assembly 5 also includes an arc-shaped plate 504, which is snapped onto the outer surface of the slide rod 3. An inclined plate 505 is fixedly connected to the outer surface of the arc-shaped plate 504, and a pad 506 is fixedly connected to the bottom end of the inclined plate 505. Through the snapping between the arc-shaped plate 504 and the slide rod 3, and with the pad 506, the device can be fixed again, ensuring the effectiveness of the device in subsequent use.

[0032] In use, when the baffle 1 is hit by gravel, the baffle 1 will move. During this process, the shock-absorbing spring 409 and the compression spring 403 will be compressed to different degrees. First, during the compression of the shock-absorbing spring 409, the long rod 408 will begin to slide on the surface of the connecting rod 407, which can guide the movement of the baffle 1 to a certain extent. At the same time, the shock-absorbing spring 409 can also buffer the force of the movement of the baffle 1 to a certain extent during the compression process. When the compression spring 403 is compressed, the hinge rod 405 will change angle. Then, the remaining force after buffering will push the compression spring 403 to compress. At the same time, the force will be transmitted to the damper 410, which will further buffer the force of the movement of the baffle 1. Thus, this device can protect against gravel after blasting, ensure the personal safety of the personnel, and improve the practicality of the device. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.
