Description

Technical Field

[0001] The utility model relates to the technical field of mine safety equipment, in particular to a portable and mobile open-air blasting shelter. Background Art

[0002] The traditional mining industry has always used the drilling-charging-blasting process to break rocks, which has been the case for both open-pit and underground mining over the years. Whether in terms of economic benefits or mining efficiency, there is no effective way to replace the drilling and blasting method. At the same time, since mine blasting will inevitably produce flying rocks, endangering the safety of on-site personnel, facilities, and equipment, causing casualties and property losses, relevant personnel need to evacuate safely or enter the bomb shelter to avoid flying rocks before detonation to achieve effective protection of personnel.

[0003] Although traditional bomb shelters are solidly constructed, compact, strong and durable, they are heavy and bulky, making them inconvenient to transport or move. Especially when used in mines in plateaus and cold regions, the difficulty of transportation and transfer is further increased, making them extremely inconvenient in practical applications. Utility Model Content

[0006] The supporting mechanism includes supports respectively fixed on the left and right sides of the upper part of the protective plate; a first connecting rod is hinged in the support; the lower end of the first connecting rod is fixedly connected to the supporting base plate by a first connecting bolt; when the supporting base plate and the first connecting rod are rotated to a vertical state, the first connecting rod is in front of the supporting base plate; second connecting rods are respectively hinged on the left and right sides of the front end of the roof covering plate; a sleeve clamp is hinged at the lower end of the second connecting rod; the sleeve clamp is fixedly connected to the first connecting rod by a second connecting bolt; when the top surface of the roof covering plate is rotated to the front side of the protective plate and is in a vertical state, the roof covering plate is in front of the first connecting rod.

[0007] To further optimize the technical solution, through grooves are respectively opened on the left and right sides of the upper end of the supporting base plate of the portable mobile open-air blasting shelter along the front-to-back direction; a plurality of penetration holes are sequentially opened in the through groove from front to back; the first connecting bolt corresponds to the penetration hole; grooves are respectively opened on the left and right ends of the supporting base plate along the front-to-back direction; the penetration hole passes through the groove; and the groove is used to hide the bolt head of the first connecting bolt.

[0008] To further optimize the technical solution, a plurality of through holes are sequentially opened on the first connecting rod of the portable mobile open-air blasting shelter along the length direction; and the second connecting bolts correspond to the through holes.

[0009] To further optimize the technical solution, a positioning block is fixed on the left end of the protective plate of the portable mobile open-air blasting shelter; a slot is opened on the front side of the right end of the protective plate; the positioning block corresponds to the slot; and corresponding connecting holes are opened on the positioning block and the slot respectively.

[0010] To further optimize the technical solution, a plurality of ground nail insertion holes are provided on the supporting bottom plate of the portable mobile open-air blasting shelter.

[0013] 2. The protective plate and the supporting base plate are connected and fixed by the first connecting rod, so that the supporting base plate can play a role in stabilizing the support of the protective plate. The protective plate, the supporting base plate and the first connecting rod can form a stable triangular structure to ensure that the protective plate is stable and firm after being erected. Similarly, the roof cover plate and the first connecting rod can be connected and fixed by the second connecting rod, so that the second connecting rod, the first connecting rod and the roof cover plate also form a stable triangular structure to ensure that the roof cover plate is stable and firm after arrangement.

[0014] 3. When the supporting base plate and the first connecting rod are rotated to a vertical state, the first connecting rod is located in front of the supporting base plate; when the top surface of the roof cover is rotated to the front side of the protective plate and is in a vertical state, the roof cover is located in front of the first connecting rod; by hingedly rotating the supporting base plate, the first connecting rod, and the roof cover in sequence, the device can be folded and arranged, thereby effectively reducing the occupied space and bringing convenience to transportation and movement.
