Description

Technical Field

[0001] The utility model relates to the field of construction equipment, in particular to a roadbed deep excavation protection device. Background Art

[0002] The roadbed refers to the basic structure used to bear the road surface and traffic loads when building roads, railways and other transportation projects. It is the basic part of the entire road or railway project, supporting the upper road surface and transferring the traffic load to the foundation soil. The roadbed usually consists of the following main parts: Roadbed filler (base bed): Roadbed filler refers to the earth, stone or other suitable materials laid on the roadbed. It bears the vehicle load and transfers the load to the foundation soil. The selection of roadbed filler depends on the requirements of the project, geological conditions and material availability. Roadbed slope: The roadbed slope is the inclined part of the side of the roadbed. Its function is to support the roadbed filler and prevent the soil from sliding or collapsing laterally. The slope and stability of the roadbed slope are crucial to the safety and durability of road projects. When digging deep roadbeds, workers need to enter the excavation area to work. The use of protective devices can provide necessary safety protection to prevent earth collapse or collapse, thereby reducing the risk of worker injury. This device can prevent earth from falling, sliding or collapsing, protecting workers from accidental injuries.

[0003] Traditional protective devices mostly use shotcrete, which is a solid surface formed by spraying concrete materials to cover the soil surface in the deep excavation area of ​​the roadbed. This method can enhance the stability of the soil and prevent soil landslides or collapses.

[0004] However, the spraying method used in traditional protective devices usually has a fixed spraying direction, which will limit the coverage of construction workers. When construction needs to be carried out at a specific angle or in a difficult-to-reach area, this limitation may lead to low construction efficiency or inability to complete the task. Therefore, a roadbed deep excavation protective device is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a roadbed deep excavation protection device, including a shotcrete machine 1, the output end of the shotcrete machine 1 is fixedly connected with a conduit 3, the outer wall of the conduit 3 is fixedly connected with a fixing plate 29, the inside of the fixing plate 29 is fixedly connected with a hose 28, the bottom end of the hose 28 is fixedly connected to one end of the fixing plate 29, the outer wall of the hose 28 is fixedly connected with a connecting shell 2, the inside of the connecting shell 2 is rotatably connected with a worm gear 14, the inside of the connecting shell 2 is rotatably connected with a worm 7, and the worm 7 Meshed with worm gear 2 14, the outer wall of worm gear 2 14 is fixedly connected with a rotating disk 13, the top of rotating disk 13 is fixedly connected with a fixed block 12, the interior of fixed block 12 is rotatably connected with worm 2 9, the interior of fixed block 12 is rotatably connected with worm gear 10, worm gear 10 is meshed with worm gear 2 9, the outer wall of worm gear 10 is rotatably connected with a rotating plate 11, the interior of rotating plate 11 is rotatably connected with a rotating disk 8, the interior of rotating disk 8 is fixedly connected with a hose 28, and one end of the outer wall of worm gear 1 7 is fixedly connected with a switch assembly.

[0034] Specifically, the worm 1 7 is rotated and the meshing between the worm 1 and the worm gear 14 is utilized to ensure the transmission of large torque and moment, thereby driving the rotating disk 13 to rotate through the worm gear 14, and then driving the fixed block 12 to rotate through the rotating disk 13, and then the worm 2 9 is rotated and the meshing between the worm 1 and the worm gear 10 is utilized to ensure the transmission of large torque and moment, thereby driving the rotating plate 11 to rotate through the worm gear 10, and then driving the rotating disc 8 to rotate through the rotating plate 11, thereby driving the nozzle to adjust the angle. By adjusting the angle of the nozzle, the construction personnel can more accurately control the direction and coverage of concrete spraying, which can help them complete the construction tasks more efficiently, reduce concrete waste, and ensure construction quality.

[0035] Reference Figure 2 and Figure 3 The switch assembly includes a knob 1 4 and a knob 2 5, wherein the outer wall of the knob 1 4 is fixedly connected to one end of the outer wall of the worm 1 7, and the outer wall of the knob 2 5 is fixedly connected to one end of the outer wall of the worm 2 9.

[0036] Specifically, the corresponding worms are driven to rotate by the knob 1 4 and the knob 2 5, and the concave-convex texture can increase the friction between the knob surface and the operator's fingers. In this way, even if the fingers are sweaty or wet, the operator can still turn the knob more easily without slipping or sliding unsteadily.

[0037] Reference Figure 2 , Figure 4 and Figure 5 The top of the rotating disc 8 is fixedly connected with a fixed shell 18, a limiting groove 17 is opened inside the fixed shell 18, a slide rail 19 is opened inside the fixed shell 18, a frosting nozzle 16 is slidably connected inside the fixed shell 18, the outer wall of the frosting nozzle 16 is slidably connected inside the limiting groove 17, a block 15 is fixedly connected to the outer wall of the frosting nozzle 16, and the outer wall of the block 15 is slidably connected inside the slide rail 19, a fixed shell 20 is fixedly connected to the top of the fixed plate 29, a limiting groove 22 is opened inside the fixed shell 20, and a lifting column 1 is slidably connected inside the fixed shell 20 23, the outer wall of the lifting column 23 is fixedly connected with the sliding column 21, the outer wall of the sliding column 21 is slidably connected to the inside of the limiting groove 22, the lifting column 23 is slidably connected to the lifting column 24, the inner wall of the lifting column 24 is threadedly connected with the threaded column 25, the top of the lifting column 24 is fixedly connected to the bottom of the connecting shell 2, the inner wall of the threaded column 25 is threadedly connected with the screw rod 26, the inner wall of the threaded column 25 is fixedly connected with the connecting column 27, the outer side of the connecting column 27 is slidably connected to the inside of the lifting column 23, the outer wall of the screw rod 26 is threadedly connected to the inner wall of the lifting column 23, and the bottom of the threaded column 25 is fixedly connected with the knob 3 6.

[0038] Specifically, the frosted nozzle 16 is placed inside the limiting groove 17. Since the surface of the frosted nozzle 16 is frosted, the friction can be increased. Then the frosted nozzle 16 is rotated, and the block 15 is driven by the frosted nozzle 16 to slide inside the slide rail 19 and jam it, so that the frosted nozzle 16 can be replaced conveniently. The process is very fast, so the downtime of the equipment can be reduced. The construction personnel can complete the replacement of the nozzle in a short time and immediately resume the construction, thereby maintaining the continuity and efficiency of the construction. Then the knob 3 6 is rotated, and the screw rod 26 is driven by the knob 3 6 to move forward. The threaded column 25 is rotated, and then the lifting column 1 23 is lifted and lowered through the screw rod 26, and the threaded column 25 is rotated through the screw rod 26. When the lifting column 1 23 is lifted, the threaded column 25 is also lifted and lowered.

[0039] Working principle: Place the frosting nozzle 16 inside the limiting groove 17 of the sliding connection, then rotate the frosting nozzle 16, and drive the fixedly connected block 15 to move inside the sliding rail 19 of the sliding connection through the frosting nozzle 16, so as to replace it, and then the shotcrete machine 1 can be turned on, and during the operation, the knob 14 can be rotated to drive the fixedly connected worm 17 to rotate, and then the worm 17 drives the meshing connected worm gear 2 14 to rotate, and then the worm gear 2 14 drives the fixedly connected rotating disk 13 to rotate, and then the rotating disk 13 drives the fixedly connected fixed block 12 to rotate, and then the knob 14 is rotated to drive the fixedly connected worm 2 9 to rotate through the knob 14, and then the worm 2 9 drives the fixedly connected worm 17 to rotate. The meshingly connected worm gear 10 rotates, and then the fixedly connected rotating plate 11 is driven to rotate through the worm gear 10, and then the rotating disc 8 connected to the rotation is driven to rotate through the rotating plate 11, so as to adjust the angle of the frosting nozzle 16, and then the knob 3 6 can be rotated, and the fixedly connected screw rod 26 is driven to rotate through the knob 3 6, and then the threaded lifting column 1 23 is driven to be lifted and lowered through the screw rod 26, and at the same time, the threaded column 25 is driven to rotate and lift on the outer wall of the slidingly connected lifting column 1 23 through the screw rod 26, and then the threaded lifting column 24 is driven to be lifted and lowered through the threaded column 25, and then the fixedly connected connecting shell 2 is driven to be lifted and lowered through the lifting column 24, so as to drive the frosting nozzle 16 to extend.
