Description

Technical Field

[0001] This utility model relates to the field of blasting protection technology, specifically a safety protection device for controlled blasting with low disturbance. Background Technology

[0002] With technological advancements, low-disturbance controlled blasting techniques have emerged to address the shortcomings of traditional blasting methods. For example, methods such as large-circulation low-disturbance blasting combining multi-point initiation within the borehole and a combination of deep and shallow boreholes, as well as blasting techniques combining frozen shaft shaped charge and time delay, effectively reduce damage to the surrounding rock and improve blasting efficiency. To further ensure the safety of blasting operations and reduce harm to the surrounding environment and personnel, specialized safety protection devices need to be developed.

[0003] Existing devices primarily rely on baffle assemblies for protection. Many existing technologies resemble blasting safety devices. The structure of device CN220583227U includes a support plate with mounting plates fixedly connected to both ends of its bottom. The bottom of the mounting plates has adjustable telescopic sections for the walking mechanism. A protective mounting pad is located on the front of the support plate, with a locking mechanism between the pad and the support plate. Insertion sections for securing the support plate are located on both the front and rear sides of the top of the mounting plates. This invention can prevent the blasting sensation and shockwave generated during blasting from reducing the stability of the protective device. However, there are still areas for improvement.

[0004] Existing devices mainly use baffles to block the shock wave of blasting, which makes it difficult to store the baffle plates in some devices, thus making it inconvenient to transport the baffle assembly. At the same time, some devices are difficult to connect to multiple sets of protective devices, thus making it difficult to stably install the baffle assembly, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a safety protection device for weak disturbance control blasting is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection device for controlled blasting with low disturbance, so as to solve the problems mentioned in the background art. The existing devices mainly use baffles to block the shock wave of blasting, which makes it difficult for some devices to store the baffle plates, thus making it inconvenient to transport the baffle assembly. At the same time, some devices are difficult to connect to multiple sets of protective devices, thus making it inconvenient to stably install the baffle assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for controlled blasting with weak disturbance, comprising a storage rack, a winding roller movably connected in the middle of the storage rack, a roller shutter baffle fixedly connected to the outer wall of the winding roller, a plug connector fixedly connected to the right side of the roller shutter baffle, a socket fixedly connected to the left side of the storage rack, and a transmission box fixedly connected to the top of the storage rack.

[0007] The transmission box is equipped with a winding mechanism, which includes a transmission worm gear. The right end of the transmission worm gear is movably connected to the right side of the inner wall of the transmission box. The storage rack is equipped with a snap-fit ​​mechanism on the left side, which includes a fixing plate. The right side of the fixing plate is fixedly connected to the front left side of the storage rack.

[0008] Preferably, the left end of the transmission worm passes through the transmission box and is fixedly connected to a first torsion cover, and a transmission worm wheel is meshed with the front side of the outer wall of the transmission worm.

[0009] Preferably, a rotating shaft is fixedly connected to the inner wall of the transmission worm gear, the top end of the rotating shaft is movably connected to the top of the inner wall of the transmission box, and the bottom end of the rotating shaft passes through the top of the storage rack and is fixedly connected to the main gear.

[0010] Preferably, an internal gear is meshed with the front side of the outer wall of the main gear, and the bottom of the internal gear is fixedly connected to the top outer ring of the take-up roller.

[0011] Preferably, the rear side of the fixing plate is provided with a clamping plate, and the front middle of the clamping plate is fixedly connected with a push bolt. The front end of the push bolt passes through the fixing plate and is fixedly connected with a second twist cap.

[0012] Preferably, the outer wall of the push bolt is threaded with a fixing nut, and the rear side of the fixing nut is fixedly connected to the middle of the front side of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes a winding mechanism with a transmission worm, a first twist cover, a transmission worm wheel, a rotating shaft, a main gear, and an internal gear. By rotating the first twist cover clockwise, the transmission worm is limited to a certain position. The transmission worm meshes with the transmission worm wheel, the rotating shaft, and the main gear, which in turn mesh with the internal gear and the winding roller, thus enabling the winding roller to wind up the roller shutter baffle. This achieves the winding of the roller shutter baffle, allowing some parts of the device to store the baffle pieces, facilitating the handling of the baffle assembly, and improving the convenience and practicality of the device.

[0015] 2. This utility model uses a snap-fit ​​mechanism consisting of a fixing plate, a snap-fit ​​plate, a push bolt, a second twist cap, and a fixing nut to insert the connector of the first set of protective devices into the socket of the second set of protective devices. Then, rotating the second twist cap clockwise causes the push bolt to rotate to a limit position. The push bolt is restricted by the fixing nut and causes the snap-fit ​​plate to slide forward, so that the snap-fit ​​plate engages with the connector. This allows some devices to connect to multiple sets of protective devices, facilitates stable installation of the baffle assembly, and improves the stability and practicality of the device.

[0024] The transmission box 16 is equipped with a winding mechanism 2, which includes a transmission worm 21. The right end of the transmission worm 21 is movably connected to the right side of the inner wall of the transmission box 16, and the left end of the transmission worm 21 passes through the transmission box 16 and is fixedly connected to a first twist cover 22. A transmission worm wheel 23 is meshed with the front side of the outer wall of the transmission worm 21. Through this design, the transmission worm 21 is limited to rotate by the first twist cover 22, so that the transmission worm 21 meshes with and drives the transmission worm wheel 23 to rotate. A rotating shaft 24 is fixedly connected to the inner wall of the transmission worm wheel 23. The top end of shaft 24 is movably connected to the top of the inner wall of transmission box 16. The bottom end of rotating shaft 24 passes through the top of storage rack 11 and is fixedly connected to main gear 25. Through this design, the transmission worm gear 23 drives rotating shaft 24 and main gear 25 to rotate in a limited position. The front side of the outer wall of main gear 25 is meshed with inner gear 26. The bottom of inner gear 26 is fixedly connected to the top outer ring of take-up roller 12. Through this design, the main gear 25 meshes and drives inner gear 26 and take-up roller 12 to rotate in a limited position, which facilitates the take-up roller 12 to take up and put down the shutter baffle 13.

[0025] The storage rack 11 has a locking mechanism 3 on its left side. The locking mechanism 3 includes a fixing plate 31. The right side of the fixing plate 31 is fixedly connected to the front left side of the storage rack 11. The rear side of the fixing plate 31 has a locking plate 32.

The rear side of the fixing nut 35 is fixedly connected to the front middle of the fixing plate 31. Through this design, the push bolt 33 is restricted by the fixing nut 35 and drives the locking plate 32 to slide back and forth.

[0026] Working principle: When the roller shutter baffle 13 needs to be rolled up, the first twist cover 22 is rotated clockwise. The first twist cover 22 drives the transmission worm gear 21 to rotate to a limit position. The transmission worm gear 21 meshes and drives the transmission worm wheel 23 to rotate. The transmission worm wheel 23 drives the rotating shaft 24 to rotate to a limit position. The rotating shaft 24 drives the main gear 25 to rotate synchronously. The main gear 25 meshes and drives the inner gear 26 to rotate.
