Technical Field
[0001] This utility model relates to the field of civil engineering technology, specifically a protective device for blasting construction on steep road cut slopes. Background Technology
[0002] In infrastructure construction, mining and other engineering fields, blasting construction on steep road cut slopes is a common and critical operation. With the continuous expansion of project scale and the increasing demands of construction, blasting construction faces many challenges, among which the problems of blasting impact and debris splashing are particularly prominent, posing a serious threat to the safety of construction personnel and the surrounding environment.
[0003] When blasting steep road cut slopes, the enormous energy released instantaneously generates a strong shock wave. The shock wave carries a large amount of rock debris that flies out in all directions at high speed. These debris have great kinetic energy, and if they hit construction workers, they can cause serious bodily injuries such as abrasions, contusions, fractures, or even endanger their lives. Therefore, it is necessary to design a protective device for blasting construction on steep road cut slopes to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a protective device for blasting construction on steep road cut slopes, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for blasting construction on steep road cut slopes, including a support base, a rotating rod connected to the internal bearing of the support base, multiple sets of baffles installed on the top of the rotating rod, support seats installed on the upper and lower sides of the multiple sets of baffles, and a hinge plate hinged between each pair of support seats.
[0006] The baffle is provided with sliding grooves on both sides, and a support rod is slidably connected inside the sliding groove. A limiting component is installed between the bottom of the support rod and the support base, and the limiting component makes multiple baffles stand upright inside the support base.
[0007] Preferably, the limiting component includes a limiting groove and a limiting plate. The two sets of limiting grooves are respectively opened on both sides of the inside of the support base. The limiting plate is slidably connected inside the limiting groove to limit the multiple sets of baffles. A disassembly component is installed between the multiple sets of support rods and the limiting plate.
[0008] Preferably, the disassembly assembly includes a threaded seat and a screw, with multiple sets of threaded seats respectively opened at the top end of the support rod and the limiting plate, and the screw installed at the bottom of the multiple sets of support rods.
[0009] Preferably, a placement groove is provided on one side of the inner side of the support base, and the support rod and the limiting plate can be placed in the placement groove.
[0010] Preferably, a transparent plate is installed inside the topmost baffle, and a pull rod is installed on the top side of the topmost baffle, pulling the pull rod will move multiple sets of baffles.
[0011] Preferably, the outer hinge of the support base is connected to a baffle, which is flipped to cover the baffle and the support rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By pulling the topmost baffle, multiple baffles are brought into an upright position. The support rod is moved and inserted into the grooves on both sides of the baffles to support them. The limiting components installed between the support rod and the support base ensure that the baffles stand upright within the support base. Personnel can take shelter behind the baffles to cushion the impact of the explosion and prevent injury from flying debris. To disassemble the baffles, simply pull the support rod out of the groove and release the limiting components. The multiple baffles are then stacked within the support base for storage using the hinge seats and hinge plates installed between them.
[0014] 2. By connecting the screw installed at the bottom of the support rod to the threaded seat at one end of the limiting plate, the support rod is connected to the limiting plate. At the same time, multiple sets of support rods are connected in the same way. The support rod is inserted into the slide groove, so that the limiting plate is slidably connected in the limiting groove, thus preventing multiple sets of baffles from shifting.

[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] Please refer to Figure 1-4 As shown, this utility model provides a protective device for blasting construction on steep road cut slopes, including a support base 1, a rotating rod 2 connected to the internal bearing of the support base 1, multiple sets of baffles 3 installed on the top of the rotating rod 2, support seats 4 installed on the upper and lower sides of the multiple sets of baffles 3 respectively, and a hinge plate 5 is hinged between each two sets of support seats 4.
[0023] The baffle 3 has a sliding groove 6 on each side. A support rod 8 is slidably connected inside the sliding groove 6. A limit component is installed between the bottom of the support rod 8 and the support base 1. The limit component makes multiple baffles 3 stand upright inside the support base 1.
[0024] Specifically, by pulling the topmost baffle 3, multiple baffles 3 are brought into an upright position. The support rod 8 is moved and inserted into the sliding grooves 6 on both sides of the multiple baffles 3, which support the baffles 3. The limiting component installed between the support rod 8 and the support base 1 makes the multiple baffles 3 stand upright in the support base 1, buffering the impact generated during the explosion and preventing debris from flying and injuring personnel. When disassembling the baffles 3, simply pull the support rod 8 out of the sliding groove 6 and release the limiting component. The multiple baffles 3 are stacked in the support base 1 for storage using the hinge seat 4 and hinge plate 5 installed between the multiple baffles 3.
[0025] The limiting component includes a limiting groove 7 and a limiting plate 9. Two sets of limiting grooves 7 are respectively opened on both sides of the inside of the support base 1. The limiting plate 9 is slidably connected inside the limiting groove 7 to limit the multiple sets of baffles 3. A disassembly component is installed between the multiple sets of support rods 8 and the limiting plate 9. The disassembly component installed between the multiple sets of support rods 8 and the limiting plate 9 makes the limiting plate 9 connected to the bottom of the support rod 8. The support rod 8 is inserted into the sliding groove 6, so that the limiting plate 9 is slidably connected in the limiting groove 7 to prevent the multiple sets of baffles 3 from shifting.
[0026] The disassembly assembly includes a threaded seat 10 and a screw 11. Multiple threaded seats 10 are respectively opened at the top end of the support rod 8 and the limiting plate 9. The screw 11 is installed at the bottom of the multiple support rods 8. By threading the screw 11 installed at the bottom of the support rod 8 into the threaded seat 10 opened at one end of the limiting plate 9, the support rod 8 and the limiting plate 9 are connected. At the same time, the multiple support rods 8 are connected to each other in the same way. Conversely, the multiple support rods 8 and the limiting plate 9 can be disassembled.
[0027] The support base 1 has a placement slot 12 on one side inside, and the support rod 8 and the limiting plate 9 can be placed in the placement slot 12. The disassembled support rod 8 and the limiting plate 9 are placed in the placement slot 12 inside the support base 1 for storage.
[0028] Among them: a transparent plate 13 is installed inside the topmost baffle 3, and a pull rod 14 is installed on the top side of the topmost baffle 3. Pulling the pull rod 14 moves multiple sets of baffles 3, so that the baffles 3 are in an upright position. The blasting situation can be observed by using the transparent plate 13 installed inside one of the baffles 3.
[0029] Among them: the outer hinge of the support base 1 is connected to a baffle 15. The baffle 15 is flipped to cover the baffle 3 and the support rod 8. By flipping the baffle 15, the baffle 15 can cover multiple sets of baffles 3 and support rods 8. The baffle 15 can be opened to operate the baffle 8 and support rods 8.
[0030] Working Principle: This utility model provides a protective device for blasting construction on steep road cut slopes. Pulling the tie rod 14 moves multiple sets of baffles 3 into an upright position. The screw 11 installed at the bottom of the support rod 8 is threaded into the threaded seat 10 at one end of the limiting plate 9, thus connecting the support rod 8 to the limiting plate 9. Multiple sets of support rods 8 are connected in the same way. The support rod 8 is inserted into the sliding grooves 6 on both sides of the multiple sets of baffles 3, providing support for the baffles 3. At the same time, the limiting plate 9 installed at the bottom of the support rod 8 is slidably connected to the limiting plate 9. Within the slot 7, multiple sets of baffles 3 are prevented from shifting. The multiple sets of baffles 3 are erected within the support base 1, allowing personnel to take cover behind the baffles to buffer the impact generated during the explosion and to prevent debris from flying and injuring personnel during the explosion. When disassembling the baffles 3, simply pull the support rod 8 out of the slide groove 6 and simultaneously disengage the limiting plate 9 from the limiting slot 7. Using the hinge seat 4 and hinge plate 5 installed between the multiple sets of baffles 3, the multiple sets of baffles 3 are stacked within the support base 1 for storage.
