Description

Technical Field

[0001] This utility model relates to the field of building blasting, and more specifically, to a safety buffer structure for blasting buildings sensitive to nearby vibrations. Background Technology

[0002] Currently, blasting has become the main method in building demolition, which is efficient and economical. However, because blasting generates shock waves, it poses certain safety issues. If protective measures are not taken during blasting, it can bring significant safety and environmental hazards to the city and its residents.

[0003] However, existing devices are mostly fixedly connected in use, which makes it impossible to disassemble the devices. This results in the devices occupying a lot of space during movement and transportation, making it inconvenient to move and transport the devices.

[0004] Therefore, a safety buffer structure for nearby vibration-sensitive buildings in case of blasting is proposed to address the above issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety buffer structure for the demolition of buildings sensitive to nearby vibrations, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety buffer structure for blasting near vibration-sensitive buildings, including a base, a rotating seat rotatably connected to the upper surface of one side of the base, and limit components symmetrically arranged on both sides of the bottom wall of the base. The limit components can limit and fix the position of the rotating seat. Four limit seats are fixedly welded to the inner side wall of the rotating seat, and the four limit seats are arranged in a matrix. A connecting rod is movably inserted into each of the four limit seats. A connecting ring is threaded to one end of each of the four connecting rods. The four connecting rings are fixedly welded to the surface of the shock-absorbing plate. A buffer spring is sleeved and connected to the outside of each of the four connecting rods.

[0007] Preferably, the limiting component includes a plug rod and a limiting spring. A connecting groove is provided on both sides of the bottom wall of the base. A plug rod is movably inserted into each of the two connecting grooves. A limiting spring is sleeved on the outside of each of the two plug rods. A pulling block is fixedly connected to one end of the limiting spring. A plug hole is provided on one side of the rotating seat to be inserted and connected to one end of the plug rod.

[0008] Preferably, the bottom wall of the base has an installation groove, and a shock-absorbing material plate for blasting shock absorption is installed in the installation groove.

[0009] Preferably, two limiting blocks are symmetrically fixedly welded to the upper surface of the base, and two limiting grooves are opened on the bottom wall of the shock-absorbing plate to limit and slide with the limiting blocks.

[0010] Preferably, two notches corresponding to the limiting blocks are symmetrically formed at the edge of the rotating seat.

[0011] Preferably, the inner side of the connecting ring is provided with an internal thread, and one end of the connecting rod is provided with an external thread that engages with the thread of the connecting ring.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with existing technologies, the shock-absorbing plate can be disassembled, and the rotating seat can be rotated to close the base and the rotating seat. Through the screw connection of the connecting ring and the connecting rod, the connecting rod and the buffer spring can be disassembled and disassembled. The disassembled parts can be stored in the storage space formed by the closed base and the rotating seat to avoid scattering and loss of parts, which would affect the next installation and use.

[0014] 2. Compared with the existing technology, by setting the limiting component, the rotating seat that is closed on the base can be limited, which prevents the base and rotating seat from opening during the movement and transportation of the device, causing the various parts stored in the storage space formed by the closed base and rotating seat to fall out and be lost.

[0020] 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.

[0021] Example 1

[0022] As attached Figures 1 to 4 The safety buffer structure for near vibration-sensitive building blasting shown includes a base 1, a rotating seat 2 rotatably connected to the upper surface of one side of the base 1, and limit components symmetrically arranged on both sides of the bottom wall of the base 1, which can limit and fix the position of the rotating seat 2. Then, four limit seats 7 are fixedly welded to the inner side wall of the rotating seat 2, and the four limit seats 7 are arranged in a matrix. A connecting rod 5 is movably inserted into each of the four limit seats 7. A connecting ring 4 is threaded to one end of each of the four connecting rods 5. The four connecting rings 4 are fixedly welded to the surface of the damping plate 3. A buffer spring 6 is sleeved and connected to the outside of each of the four connecting rods 5.

[0023] Specifically, when disassembling and moving the device, the shock-absorbing plate 3 can be slid off the upper surface of the base 1 first. Then, the connecting rod 5 can be rotated to remove it from the shock-absorbing plate 3. Next, the buffer spring 6 can be removed from the outside of the connecting rod 5. Finally, the rotating seat 2 can be rotated to close it. Since the rotating seat 2 is equipped with a storage slot, a storage space will be formed between the base 1 and the rotating seat 2 when the rotating seat 2 is rotated to close it. The disassembled parts can be stored in the storage space formed by the closing of the base 1 and the rotating seat 2 to avoid scattering and loss of parts, which would affect the next installation and use.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the limiting component includes a rod 13 and a limiting spring 14. A connecting groove 12 is provided on both sides of the bottom wall of the base 1. A rod 13 is movably inserted into each of the two connecting grooves 12. A limiting spring 14 is sleeved on the outer side of each rod 13. A pulling block 15 is fixedly connected to one end of the limiting spring 14. A socket 16 is provided on one side of the rotating seat 2, which is inserted into one end of the rod 13. Furthermore, when limiting and fixing the closed rotating seat 2, the rod 13 can be pulled by the pulling block 15 first, then the rotating seat 2 can be rotated, and then the pulling block 15 can be released. At this time, the stretched limiting spring 14, since one end is fixedly connected to the pulling block 15, elastically pulls the pulling block 15 when it is released, thereby causing the pulled block 15 to move the rod 13 closer to the socket 16 on the rotating seat 2, thus limiting and fixing the rotating seat 2.

[0027] In a preferred embodiment, the bottom wall of the base 1 is provided with an installation groove 10, and a shock-absorbing material plate 11 for blasting shock absorption is installed in the installation groove 10; furthermore, the shock-absorbing material plate 11 can buffer the vibration at the bottom, wherein the shock-absorbing material plate 11 is made of shock-absorbing material, and the shock-absorbing material includes, but is not limited to, rubber, foam, etc.

[0028] In a preferred embodiment, two limiting blocks 8 are symmetrically fixedly welded to the upper surface of the base 1, and two limiting grooves 9 are opened on the bottom wall of the shock-absorbing plate 3 to limit and slide in connection with the limiting blocks 8. Furthermore, two notches corresponding to the limiting blocks 8 are symmetrically opened at the edge of the rotating seat 2. The sliding connection between the limiting blocks 8 and the limiting grooves 9 allows the shock-absorbing plate 3 to slide stably when it moves due to external vibration. The two notches symmetrically opened at the edge of the rotating seat 2 can fit tightly against the base 1 when the rotating seat 2 rotates and closes.

[0029] In a preferred embodiment, the inner side of the connecting ring 4 is provided with an internal thread, and the outer side of one end of the connecting rod 5 is provided with an external thread that engages with the thread of the connecting ring 4; furthermore, through the cooperation between the internal thread on the inner side of the connecting ring 4 and the external thread on the outer side of one end of the connecting rod 5, the connecting ring 4 and the connecting rod 5 can be easily connected and disassembled.

[0030] The working process of this utility model is as follows: First, a ring of isolation grooves 17 is dug around the outer side of the building to be blasted. Then, the connecting rod 5 is screwed and connected to the connecting ring 4. Next, the buffer spring 6 is sleeved on the outside of the connecting rod 5. Then, the limiting groove 9 opened on the bottom wall of the shock absorber 3 is slidably connected to the limiting block 8 opened on the upper surface of the base 1, so that the shock absorber 3 can be slidably set on the upper surface of the base 1. Then, one end of the four connecting rods 5 will gradually approach the limiting seat 7 and be inserted into the limiting seat 7. Then, the entire device is placed in the dug isolation groove. Within the isolation groove 17, the rear wall of the rotating seat 2 contacts and connects with one side wall of the isolation groove 17, while one side wall of the damping plate 3 abuts against the other side wall of the isolation groove 17. The damping plate 3 is limited by the side wall of the isolation groove 17, thereby preventing the connecting rod 5 installed on the rear wall of the damping plate 3 from detaching from the limiting seat 7. Furthermore, the position of the damping plate 3 within the isolation groove 17 is closer to the blasted building. During the blasting of the building, the vibration will first be transmitted to the damping plate 3, and then the damping plate 3 will squeeze the insertion hole 16. The deformation of the insertion hole 16 will buffer and absorb the vibration.

[0031] When the entire device needs to be moved and transported, the shock-absorbing plate 3 can be slid off from the upper surface of the base 1 first, then the connecting rod 5 can be rotated to remove it from the shock-absorbing plate 3. Next, the buffer spring 6 can be removed from the outside of the connecting rod 5. Finally, the rotating seat 2 can be rotated and closed, and the disassembled parts can be stored in the storage space formed by the closing of the base 1 and the rotating seat 2 to avoid scattering and loss of parts, which would affect the next installation and use. At the same time, the pulling block 15 can be elastically pulled by the limiting spring 14, which will cause the pulled block 15 to move the insertion rod 13 toward the insertion hole 16 opened on the rotating seat 2, thereby limiting and fixing the rotating seat 2 closed on the upper surface of the base 1. The above is the working principle of the near vibration sensitive building blasting safety buffer structure.
