Description

Technical Field

[0001] The utility model relates to the technical field of safety protection for blasting construction, and more specifically to a safety protection device for blasting construction of manually bored piles. Background Art

[0002] Blasting is a technique that uses the compression, loosening, destruction, projection, and killing effects of explosives exploding in air, water, soil, or rock to achieve a desired goal. When explosives are detonated in soil or rock, the explosive charge compresses, deforms, destroys, loosens, and projects the material. Blasting is also used during bored pile construction to remove soil and rock that is difficult to excavate. To ensure blasting safety, protective devices are installed above the excavated foundation pit.

[0003] After searching, the utility model patent with announcement number CN215810496U discloses a safety protection device for bored pile blasting construction, including a protective cover, with mounting seats fixed at the corners of the bottom surface of the protective cover, a water tank fixed on the top surface of the protective cover, a water injection hole fixed on the top surface of the water tank, a plurality of spray heads fixed on the outer wall of the water tank, a piston extrusion plate fixed inside the water tank, and a buffer assembly inside the protective cover; the patent adds a water tank on the top surface of the protective cover, and the sliding rod and the positioning sliding column are fixedly connected to the piston extrusion plate, so that when the impact plate blasts up, the piston extrusion plate is pushed to spray out the water in the water tank, thereby reducing the dust generated by the blasting, greatly improving the use effect of the device.

[0004] However, the above patent has the following shortcomings: the protective device is not easy to move, and it needs to be moved manually or by lifting machinery when different bored pile blasting operations are carried out, which is not very convenient. In addition, the protective cover needs to be fixed manually, and the protection of multiple locations requires repeated manual disassembly and assembly, which is inefficient. Therefore, we propose a safety protection device for bored pile blasting construction. Utility Model Content

[0028] In this embodiment, the servo motor 16 is used to drive the screw 17 to rotate, and the second electric hydraulic rod 14 is used to drive the screw 17 to move downward, so that the screw 17 drills into the ground to fix the protective cover 1.

[0029] For details, please refer to Figure 1 and Figure 2 The water spraying mechanism 2 includes a water tank 18 fixedly connected to the top surface of the protective cover 1, and a plurality of atomizing nozzles 19 are fixedly sleeved on the top of the side of the water tank 18. A threaded plug 22 is threadedly installed on the top surface of the water tank 18. A piston plate 20 is movably sleeved in the inner cavity of the water tank 18, and a plurality of sliding rods 21 are fixedly connected to the bottom surface of the piston plate 20. The bottom ends of the plurality of sliding rods 21 extend to the inner cavity of the protective cover 1 and are connected to the top surface of the impact plate 6.

[0030] In this embodiment, water is added to the inner cavity of the water tank 18 by removing the threaded plug 22, and the water in the inner cavity of the water tank 18 is squeezed by moving the piston plate 20 upward, so that the water is atomized and sprayed out from the atomizing nozzle 19, so as to reduce dust coming out of the pressure relief hole 3 and the wire mesh frame 4.

[0031] For details, please refer to Figure 1 A push handle 24 is fixedly installed on the side of the protective cover 1, and a control panel 25 is fixedly installed on the side of the protective cover 1.

[0032] In this embodiment, the push handle 24 is used to push the device, the control panel 25 is used to control the first electro-hydraulic rod 10 , the second electro-hydraulic rod 14 and the servo motor 16 , and the push handle 24 is used to push the device.

[0035] For details, please refer to Figure 2 The top of the protective cover 1 and the bottom of the water tank 18 are both provided with air holes 23.

[0036] In this embodiment, the air holes 23 are used to ensure that the lower part of the inner cavity of the water tank 18 is connected to the inner cavity of the protective cover 1, ensuring that the piston plate 20 can move up and down smoothly in the inner cavity of the water tank 18.

[0037] Working principle: When in use, first use the control panel 25 to control the first electric hydraulic rod 10, use the first electric hydraulic rod 10 to drive the moving wheel 11 to move down to the bottom of the mounting seat 8, and at the same time use the moving wheel 11 and the first electric hydraulic rod 10 to lift the protective cover 1. At this time, use the moving wheel 11 to drive the protective cover 1 to move, so that the protective cover 1 moves to the top of the artificial excavation pit, and then start the first electric hydraulic rod 10 to drive the moving wheel 11 to retract into the inner cavity of the first receiving tube 9, and at the same time make the bottom surface of the protective cover 1 fit with the ground above the artificial excavation pit, and then start the servo motor 16 to drive the screw nail 17 to rotate, and drive the lifting box 15 and the screw nail 17 to rotate through the second electric hydraulic rod 14. The nail 17 moves downward, so that the rotating spiral nail 17 is screwed into the ground, thereby firmly placing the protective cover 1 above the artificial excavated foundation pit, and finally the explosives in the foundation pit are remotely controlled for blasting. The impact force generated by the blasting drives the impact plate 6 to move upward, and at the same time, the compression of the spring 5 and the resistor 7 is used to absorb the impact force received by the impact plate 6. In addition, when the impact plate 6 moves upward, the slide rod 21 and the piston plate 20 move upward synchronously, and the piston plate 20 is used to push the water in the water tank 18 to be atomized and sprayed out from the atomizing nozzle 19. When the impact plate 6 moves to above the pressure relief hole 3, the dust and air pressure generated by the blasting are dispersed from the pressure relief hole 3 and the wire mesh frame 4, and the water mist sprayed from the atomizing nozzle 19 is used to reduce the dust.
