Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of slope support, in particular to a support bracket for highway slope. BACKGROUND
[0002] The support bracket for highway slope is a structure used to stabilize and protect the highway slope from instability and landslides caused by natural factors or human activities. Slope support technology is an important technology in the field of civil engineering, especially in the construction of highways in mountainous areas. The stability of the slope is directly related to the safe operation of the highway and the protection of the surrounding environment. Traditional slope support methods include retaining walls, anchor rods, sprayed concrete, soil nailing walls, etc. With the development of technology, more advanced support technologies have emerged, such as prestressed anchor cables, lattice beams, and reinforced soil retaining walls. These technologies can effectively improve the stability of the slope, reduce slope deformation, and extend the service life of the highway. In the use of existing support brackets for highway slopes to carry out slope stability maintenance work, the rock-soil mass on the slope surface will appear local peeling and settlement due to its own gravity, rainwater penetration or weathering, which will cause gaps between the support bracket and the slope surface. The original "close support" state changes to a "suspended state", the support bracket loses the counterforce support of the rock-soil mass, the stress mode changes, and local overload problems are easily caused. In addition, if the slope itself has slow deformation (such as creep), it will continuously press the support bracket for a long time, causing the support bracket to be subjected to "pushing" or "shearing" action, which is manifested as local damage at the contact part between the support bracket and the rock-soil mass, or even being crushed by embedded stones. Currently, personnel are usually arranged to conduct inspections, but due to the large range of the support bracket for highway slope and the construction location far from the city, safety hazards are difficult to be discovered in advance; therefore, the present application provides a support bracket for highway slope.

DETAILED DESCRIPTION
[0028] The application will be further explained in connection with the accompanying drawings and embodiments:
[0029] This invention provides an improved support frame for highway slopes. The technical solution of this invention is as follows:
[0030] like Figures 1-9 As shown, a support frame for a highway slope includes a support base 1. Several outer shells 2 are fixedly installed on the top of the support base 1. Each outer shell 2 has a threaded block 3 slidably disposed within its inner cavity. A vertical plate 4 is welded to the side wall of each threaded block 3. An installation cylinder 5 is welded to the side wall of each vertical plate 4. A balancing air groove 22 is penetrated through the top of each installation cylinder 5. A telescopic airbag 6 is placed inside the inner cavity of each installation cylinder 5. Air pressure sensors 21 are fixedly installed at the bottom of each of the installation cylinders 5, and the detection ends of the air pressure sensors 21 extend into the corresponding telescopic airbag 6. Each mounting cylinder 5 has a piston plate 7 slidably mounted inside its cavity. A pull rod 8 is rotatably connected to the side wall of each piston plate 7. A sliding cylinder 17 is welded to the side wall of each mounting cylinder 5. A slider 18 is slidably mounted inside the cavity of each sliding cylinder 17, and several sliders 18 are rotatably connected to the outer surface of the corresponding pull rod 8. A steel cable 9 is fixedly installed between every two pull rods 8. Several mounting blocks 10 are fixedly installed at equal intervals on each steel cable 9. A sleeve 11 is fixedly installed at the bottom of each mounting block 10. An abutment rod 12 is slidably mounted inside the cavity of each sleeve 11. Each of the 11 inner cavities is equipped with a spring 13, and several springs 13 are respectively connected between the top of the inner cavity of the corresponding sleeve 11 and the top of the corresponding abutment rod 12. Each group of sleeves 11 is connected to a segmented air tube 27. Each telescopic airbag 6 has a detection air tube 28 connected to its side wall, and the ends of several detection air tubes 28 are slidably disposed in the inner cavity of the corresponding segmented air tube 27. Several air delivery slots 29 are evenly spaced on the outer circumference of each detection air tube 28. In use, the bulge of the slope will push against the support base 1, thereby causing the support base 1 to partially... As the upward deformation occurs, the bottom of the abutment rod 12 abuts against the top of the support base 1. The deformed support base 1 will push the corresponding abutment rod 12 into the inner cavity of the sleeve 11, causing the gas in the inner cavity of the corresponding sleeve 11 to enter the telescopic airbag 6 through the segmented air pipe 27, the air delivery groove 29 and the detection air pipe 28 in sequence. This causes the air pressure inside the telescopic airbag 6 to increase. After the air pressure sensor 21 detects the electrical signal that the air pressure is maintained at a high level, it sends a warning to the early warning center, indicating that the slope itself may have slow deformation (creep) or other conditions.
[0031] Further, the bottom of each shell 2 inner cavity is rotationally connected with a threaded rod 14, and a plurality of threaded blocks 3 are threadedly connected on the corresponding threaded rods 14 respectively, the top of each threaded rod 14 is welded with a screw head 15, the top of each screw head 15 is provided with a polygonal groove 16, the output end of the electric rotating device is inserted into the polygonal groove 16 on the top of the screw head 15, the screw head 15 and the threaded rod 14 are driven to rotate by the electric rotating device, the rotating threaded rod 14 drives the threaded block 3, the vertical plate 4 and the mounting cylinder 5 to move downward, the mounting cylinder 5 drives the steel cable 9 to move downward, thereby releasing the interception of the steel cable 9 to the gravel; the inner side wall of each shell 2 is welded with a wide body rack 19, the end of each pull rod 8 is welded with a wide body gear one 20, and a plurality of wide body gear ones 20 are engaged with the corresponding wide body racks 19 respectively, the mounting cylinder 5 drives the pull rod 8 and the wide body gear one 20 to move downward, since the wide body gear one 20 is engaged with the wide body rack 19, the wide body gear one 20 moving downward will drive the steel cable 9 and the mounting block 10, the sleeve 11 and the abutting rod 12 fixed on the steel cable 9 to rotate, the sleeve 11 and the abutting rod 12 turning over will lift the gravel upward, facilitating the gravel to roll down.
[0032] Further, the side wall of each piston plate 7 is rotationally connected with a lead screw 23, the end of each lead screw 23 is welded with a wide body gear two 24 engaged with the corresponding wide body rack 19, the side end of each lead screw 23 away from the corresponding wide body gear two 24 is threadedly connected with an internally threaded cylinder 25, the end of each internally threaded cylinder 25 is welded with a pressing plate 26, the wide body gear two 24 is also driven to rotate by the wide body rack 19, the wide body gear two 24 drives the lead screw 23 to rotate, the rotating lead screw 23 drives the internally threaded cylinder 25 and the pressing plate 26 to move towards the piston plate 7, thereby pushing the stretchable air bag 6 and the piston plate 7 to move towards the shell 2, so that the steel cable 9 gradually changes from the stretched state to the straight state, in this process, the contact points of the steel cable 9 and the gravel gradually decrease, so that the gravel is more easily rolled down.
[0033] Working principle: in use, the slope uplift will push the bracket base 1, and then make the bracket base 1 locally move up and deform, because the bottom of the abutting rod 12 abuts against the top of the bracket base 1, the deformed bracket base 1 will push the corresponding abutting rod 12 to slide into the sleeve 11 cavity, and then make the gas in the corresponding sleeve 11 cavity enter the stretchable air bag 6 inside through the segmented air pipe 27, the gas conveying groove 29 and the detection air pipe 28 in turn, and then make the internal gas pressure of the stretchable air bag 6 increase, the gas pressure sensor 21 detects that the gas pressure continues to remain at a high level, and sends a warning to the early warning center, indicating that the slope itself may have slow deformation and creep; When the slope subsides, it will cause the bracket base 1 to be locally overloaded, and then make the bracket base 1 locally move down and deform, at this time, the corresponding abutting rod 12 is affected by the elastic force of the spring 13 and moves down, so that the space of the sleeve 11 cavity increases, and the gas in the stretchable air bag 6 enters the corresponding sleeve 11 in turn through the detection air pipe 28, the gas conveying groove 29 and the segmented air pipe 27, and then makes the internal gas pressure of the stretchable air bag 6 decrease, and the gas pressure sensor 21 detects that the gas pressure continues to remain at a low level, and sends a warning to the early warning center, indicating that the slope itself may have settlement; When the slope top has small stones rolling down and passing through the bottom area of the steel cable 9, the stones will hit the sleeve 11 or the abutting rod 12, and then make the abutting rod 12 not vertical to the bracket base 1 for a short time and slide outward under the action of the elastic force of the spring 13, and then make the gas pressure in the stretchable air bag 6 decrease; When the early warning center receives frequent electric signals of gas pressure decrease, it indicates that the upper area of the slope has great instability and may have landslide and other disastrous risks; When the slope top has large stones rolling down and being blocked by the steel cable 9, the impact force of the large volume stones will directly act on the steel cable 9, making the steel cable 9 pull the pull rod 8 and the piston plate 7 at both ends; First, the piston plate 7 will extrude the stretchable air bag 6, and the compression of the stretchable air bag 6 will buffer the stones once; At the same time, the gas in the stretchable air bag 6 under extrusion will enter the corresponding sleeve 11 through the detection air pipe 28, the gas conveying groove 29 and the segmented air pipe 27 and push the abutting rod 12 to slide outward, so that the abutting rod 12 abuts against the bracket base 1 more tightly, increases the friction between the abutting rod 12 and the bracket base 1, and offsets part of the impact force of the stones by means of the increased friction; In addition, the increased gas pressure in the sleeve 11 will also push the mounting block 10 and the steel cable 9 to move up a small distance, so as to avoid the stones from continuing to roll down; After the piston plate 7 sweeps the balance gas groove 22, a sealed space is formed between the piston plate 7 and the mounting cylinder 5, and the gas pressure in the space buffers the stones twice;
[0034] After the large volume of rubble is stabilized, the air pressure sensor 21 detects that the internal air pressure of the telescopic air bag 6 is continuously maintained at a high level and sends a warning to the early warning center, and the early warning center sends a special officer carrying an electric rotating device to the scene; then the output end of the electric rotating device is inserted into the polygonal groove 16 at the top of the screw head 15, and the electric rotating device drives the screw head 15 and the threaded rod 14 to rotate, the rotating threaded rod 14 drives the threaded block 3, the vertical plate 4 and the mounting cylinder 5 to move downward, the mounting cylinder 5 drives the steel cable 9 to move downward, thereby releasing the interception of the steel cable 9 to the rubble; at the same time, the mounting cylinder 5 drives the pull rod 8 and the wide gear one 20 to move downward, and since the wide gear one 20 is engaged with the wide rack 19, the downward wide gear one 20 will drive the steel cable 9 and the mounting block 10, the sleeve 11 and the abutment rod 12 fixed on the steel cable 9 to rotate, the sleeve 11 and the abutment rod 12 are turned up to lift the rubble upward, facilitating the rubble to roll down; in this process, the wide gear two 24 will also rotate under the influence of the wide rack 19, the wide gear two 24 drives the lead screw 23 to rotate, and the rotating lead screw 23 drives the inner threaded cylinder 25 and the pressure plate 26 to move towards the piston plate 7, thereby pushing the telescopic air bag 6 and the piston plate 7 to move towards the shell 2, so that the steel cable 9 gradually changes from the stretched state to the straight state, and in this process, the contact points between the steel cable 9 and the rubble gradually decrease, making it easier for the rubble to roll down; at the same time, the timing of the rubble rolling down is more controllable; it should be noted that while the pressure plate 26 pushes the telescopic air bag 6, the telescopic air bag 6 will pull the detection air pipe 28 to slide, so that the gas inlet groove 29 is tightly attached to the inner wall of the sectional air pipe 27, thereby preventing the gas in the telescopic air bag 6 from entering the sectional air pipe 27 when it is compressed; by intercepting the middle position of the falling rubble and then lifting it out, the impact force of the rubble on the anti-falling net is reduced.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
