Description

Technical Field

[0001] This utility model belongs to the technical field of blasting protection facilities, and in particular relates to a blasting safety protection buffer baffle. Background Technology

[0002] Blasting, as a scientific technology, has a wide range of applications, but its application in engineering is undoubtedly the most important and common. Mining and tunneling are carried out using the drilling and blasting method, which is used to excavate tunnels for railways and highways. Blasting is required during mining, but it produces a lot of flying rocks. It is necessary to set up some devices to prevent flying rocks from protecting the safety of workers and preventing flying rocks from causing injury to workers on the ground.

[0003] In the prior art, such as the tunnel blasting protection device disclosed in Chinese Patent (CN115823983A), a base, a main baffle and a top plate are provided. Three sleeves are provided above the base and below the top plate respectively. Three kits are welded to the upper and lower ends of the main baffle corresponding to the positions of the sleeves. The sleeves are fitted inside the kits, and shock-absorbing springs are provided between the sleeves and the kits. A buffer plate, a buffer mechanism and at least two guide screws are symmetrically arranged at the upper and lower ends of one end face of the main baffle.

[0004] This method has the following drawbacks: First, in actual use, the outermost layer of the baffle is the first to be impacted by flying debris. After prolonged use, the outer baffle will develop dents and scratches, which will reduce the baffle's protective strength. When the baffle reaches the end of its service life, it is inconvenient to replace it. Replacing the baffle requires using cutting tools to remove it, and installing a new baffle requires using welding tools to re-weld it, which is time-consuming and labor-intensive. Second, the device mainly uses springs as a means of mitigating the main impact. However, the springs need to be installed on the base via guide rods. The guide rods bear the weight of the baffle, which causes friction between the baffle and the guide rod during the impact of flying debris, resulting in wear at the joint between the baffle and the guide rod and reducing the service life of the device.

[0005] Therefore, this utility model provides a blasting safety protection buffer baffle. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model discloses a blasting safety protective buffer baffle. The protective baffle is removable and replaceable, facilitating replacement after the baffle is damaged by flying rocks and reaches the end of its service life. It is simple and convenient. While providing support for the protective baffle, it also reduces the degree of damage to the protective baffle and extends its service life. At the same time, the telescopic rod can provide elastic buffering at the connection, reducing hard friction damage at the connection and increasing the overall service life of the device.

[0007] To achieve the above technical effects, this utility model provides a blasting safety protective buffer baffle, including a fixed base, a protective component, and a buffer component. The protective component is disposed on one side of the fixed base, and the buffer component is disposed inside the fixed base. The protective component also includes a support plate and a protective baffle fixedly installed on the surface of the support plate. Two spaced connecting blocks are fixedly connected to both sides of the protective baffle. Connecting grooves adapted to the connecting blocks are opened on both sides of the support plate. Locking holes that pass through vertically are opened inside the connecting blocks. A cavity is opened between the two connecting grooves in the support plate, and a bidirectional screw is rotatably installed in the cavity. Locking rods are threaded to both ends of the bidirectional screw. Both sides of the support plate are provided with driving components for driving the bidirectional screw to rotate; The buffer assembly further includes a support rod fixedly installed in the fixed base, on which two symmetrically distributed sliders are slidably sleeved, and a first spring abuts between the two sliders. A connecting rod is hinged between the sliders and the support plate.

[0008] Preferably, a rubber protective pad is fixedly connected to the surface of the protective baffle.

[0009] Preferably, a rubber buffer pad is fixedly connected to the side of the support plate near the protective baffle.

[0010] Preferably, the driving component further includes a knob rotatably mounted on the side wall of the support plate, one end of the knob extending into the cavity and fixedly connected to a main gear, and a driven gear meshing with the main gear fixedly connected to the bidirectional screw.

[0011] Preferably, the support plate has grooves on both sides, and the knob is embedded in the grooves.

[0012] Preferably, telescopic rods are embedded at each of the four corners of the fixed base, and the other end of the telescopic rods is fixedly connected to the support plate.

[0013] Preferably, a second spring is provided inside the telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting connecting blocks and connecting grooves, allows the connecting blocks on both sides of the protective baffle to be inserted into the corresponding connecting grooves on both sides of the support plate when installing the protective baffle. Then, only the driving component needs to be operated to drive the bidirectional screw to rotate. The bidirectional screw drives the locking rod to be inserted into the locking hole, thus fixing the protective baffle. When disassembling the protective baffle, the driving component only needs to control the bidirectional screw to rotate in the opposite direction to move the locking rod out of the locking hole, so that the protective baffle can be removed for replacement. This facilitates the replacement of the protective baffle after it is damaged by flying stone impact and reaches the end of its service life. It is simple and convenient. 2. By setting up a buffer component, when the protective baffle is impacted, the impact force will push the support plate towards the fixed seat. At this time, the connecting rod will drive the two sliders to slide relative to each other along the support rod, so that the two sliders simultaneously squeeze the first spring, causing the first spring to deform and buffer the impact force. This can offset the impact on the protective baffle, provide support for the protective baffle, reduce the degree of damage to the protective baffle, and extend the service life of the protective baffle. At the same time, the telescopic rod can provide elastic buffering at the connection, reduce hard friction damage at the connection, and increase the overall service life of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] like Figures 1 to 5 As shown: The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, in actual use, the outermost layer of the baffle is the first to be impacted by flying gravel. After long-term use, the outer baffle will have dents and scratches. These dents and scratches will reduce the protective strength of the baffle. When the baffle reaches the end of its service life, it is inconvenient to replace the baffle. Replacing the baffle requires using a cutting tool to remove the baffle, and installing a new baffle requires using a welding tool to re-weld it, which is time-consuming and labor-intensive. Second, the device mainly uses springs as a means to mitigate the main impact. However, the springs need to be installed above the base through a guide rod. The guide rod bears the weight of the baffle, which causes friction between the baffle and the guide rod during the process of buffering the impact of flying gravel. This causes wear at the joint between the baffle and the guide rod, reducing the service life of the device. Therefore, the inventor provides a blasting safety protective buffer baffle, including a fixed base 1, a protective component 2, and a buffer component 3. The protective component 2 is disposed on one side of the fixed base 1, and the buffer component 3 is disposed inside the fixed base 1. The protective component 2 also includes a support plate 21 and a protective baffle 22 fixedly installed on the surface of the support plate 21. Two spaced connecting blocks 23 are fixedly connected to both sides of the protective baffle 22. Connecting grooves 24 adapted to the connecting blocks 23 are opened on both sides of the support plate 21. Locking holes 25 that pass through vertically are opened inside the connecting blocks 23. A cavity is opened between the two connecting grooves 24 on the support plate 21, and a bidirectional screw 26 is rotatably installed in the cavity. Locking rods 27 are threaded to both ends of the bidirectional screw 26. Both sides of the support plate 21 are provided with driving components 28 for driving the bidirectional screw 26 to rotate; The buffer assembly 3 also includes a support rod 31 fixedly installed in the fixed base 1. Two symmetrically distributed sliders 32 are slidably sleeved on the support rod 31. A first spring 33 abuts between the two sliders 32. A connecting rod 34 is hinged between the sliders 32 and the support plate 21.

[0018] Using the above scheme, when installing the protective baffle 22, the connecting blocks 23 on both sides of the protective baffle 22 can be inserted into the corresponding connecting slots 24 on both sides of the support plate 21. Then, only the driving component 28 needs to be operated to make the driving component 28 drive the bidirectional screw 26 to rotate. The bidirectional screw 26 drives the locking rod 27 to be inserted into the locking hole 25, thereby fixing the protective baffle 22. When disassembling the protective baffle 22, only the driving component 28 needs to control the bidirectional screw 26 to rotate in the opposite direction, so that the locking rod 27 can be moved out of the locking hole 25, and then the protective baffle 22 can be removed for replacement, which is convenient for replacing the protective baffle 22. When the protective baffle 22 is impacted, the impact force will push the support plate 21 to move towards the fixed seat 1. At this time, the connecting rod 34 will drive the two sliders 32 to slide relative to each other along the support rod 31, so that the two sliders 32 simultaneously squeeze the first spring 33, causing the first spring 33 to deform and buffer the impact force, thereby offsetting the impact on the protective baffle 22, reducing the degree of damage to the protective baffle 22, and extending the service life of the protective baffle 22.

[0019] Furthermore, a rubber protective pad 29 is fixedly connected to the surface of the protective baffle 22; When a flying stone hits the protective baffle 22, it will come into contact with the protective pad 29, which can prevent the flying stone from directly contacting the protective baffle 22 and causing wear to the protective baffle 22.

[0020] Furthermore, a rubber buffer pad 210 is fixedly connected to the side of the support plate 21 near the protective baffle 22; When the protective baffle 22 is impacted by flying stones, the buffer pad 210 can act as a buffer between the protective baffle 22 and the support plate 21, reducing the impact on the support plate 21.

[0021] Furthermore, the drive unit 28 also includes a knob 281 rotatably mounted on the side wall of the support plate 21. One end of the knob 281 extends into the cavity and is fixedly connected to the main gear 282. A driven gear 283 that meshes with the main gear 282 is fixedly connected to the bidirectional screw 26. In this configuration, by setting a driving component 28, during operation, the knob 281 can be rotated to drive the main gear 282 to rotate, which in turn drives the driven gear 283 to rotate, which in turn drives the bidirectional screw 26 to rotate.

[0022] Furthermore, grooves 211 are provided on both sides of the support plate 21, and the knob 281 is embedded in the grooves 211; The support plate 21 has grooves 211 on both sides, and the knob 281 is embedded in the grooves 211. The grooves 211 can protect the knob 281.

[0023] Furthermore, telescopic rods 11 are embedded and installed at the four corners of the fixed base 1, and the other end of the telescopic rods 11 is fixedly connected to the support plate 21. Furthermore, a second spring 12 is provided inside the telescopic rod 11; The fixed base 1 has telescopic rods 11 embedded at each of its four corners. The other end of the telescopic rods 11 is fixedly connected to the support plate 21. The telescopic rods 11 are equipped with a second spring 12. By setting the telescopic rods 11 and the second spring 12, the support plate 21 can be limited and supported, thus preventing the support plate 21 from shaking excessively.

[0024] The working principle of this utility model: First, fix the mounting base 1 in the blasting area, so that the protective baffle 22 faces the direction of the blast. The flying rocks generated during the blast will hit the protective baffle 22, preventing the flying rocks from injuring personnel.

[0025] When the protective baffle 22 is impacted, the impact force will push the support plate 21 toward the fixed seat 1. At this time, the connecting rod 34 will drive the two sliders 32 to slide relative to each other along the support rod 31, so that the two sliders 32 simultaneously squeeze the first spring 33, causing the first spring 33 to deform and buffer the impact force. This can offset the impact on the protective baffle 22, provide support for the protective baffle 22, reduce the degree of damage to the protective baffle 22, and extend the service life of the protective baffle 22.

[0026] When installing the protective baffle 22, the connecting blocks 23 on both sides of the protective baffle 22 can be inserted into the corresponding connecting slots 24 on both sides of the support plate 21. Then, only the driving component 28 needs to be operated. During operation, the knob 281 can be rotated to drive the main gear 282 to rotate, which in turn drives the driven gear 283 to rotate, which in turn drives the bidirectional screw 26 to rotate. The bidirectional screw 26 drives the locking rod 27 to be inserted into the locking hole 25, thus fixing the protective baffle 22. When disassembling the protective baffle 22, the bidirectional screw 26 can be rotated in the opposite direction by controlling the driving component 28 to move the locking rod 27 out of the locking hole 25, thereby removing the protective baffle 22 for replacement, which is convenient for replacing the protective baffle 22.

[0027] This concludes the description of the working principle of the device.
