Description

[0002] The slope formed in engineering construction often causes geological disasters such as landslides, collapses, swellings or peeling when it encounters rainy days or strong vibrations, especially if stones fall off the slope on both sides of the highway, which can cause damage to people's lives and property. In order to prevent the occurrence of the above-mentioned geological disasters, it is necessary to carry out slope management.

[0029] The elastic component 17 between the supporting plate 18 and the fixed plate 16 in the device can effectively protect the supporting plate 18 when the device is impacted by a small force, the elastic force and the buffering force generated by the elastic component 17 can effectively protect the supporting plate 18, so that the service life of the device is not shortened due to long-time impact, and the use safety of the device is further improved, and the device does not have the buffering capacity when in use, so that the device is damaged due to long-time impact, when the device is impacted by a large force, the position of the supporting plate 18 is changed, so that the impact force generated by the supporting plate 18 can be effectively buffered, and the impact force generated by the supporting plate 18 can be converted into pneumatic force, so that the angle of the supporting plate 18 and the fixed plate 16 is changed, and then part of the impact force can be unloaded in the impact process, so that the stability and safety of the device in protection are ensured, and the parts in the device cooperate with each other, so that the impact force received by the device can be buffered and unloaded according to the impact force when the device works, so that the practicality and safety of the device are further improved, and the device is more convenient and diverse in use, and the service life of the device is prolonged.

[0030] In the embodiment, the self-locking mechanism 5 comprises a fixed disc 6, a locking groove 7, a rotating disc 8, a first spring 9 and a locking block 10. The fixed disc 6 is arranged on the fixed rod 3, and the fixed disc 6 and the rotating disc 8 are sleeved on the rotating column 4. The fixed disc 6 is provided with a plurality of locking grooves 7. The rotating disc 8 is fixedly connected to the rotating column 4. The rotating disc 8 is provided with a plurality of first springs 9. The first springs 9 are provided with locking blocks 10 at the ends. The ends of the locking blocks 10 are arc-shaped. The locking blocks 10 are movably connected in the locking grooves 7 to movably connect the fixed disc 6 and the rotating disc 8. When the pneumatic mechanism 25 works, the fixed rod 3 drives the rotating column 4 to rotate on the fixed seat 2, so that the angle of the fixed rod 3 is adjusted. At this time, the rotating disc 8 rotates on the fixed disc 6. At the same time, the first springs 9 on the rotating disc 8 are compressed. When the first springs 9 are compressed, the locking blocks 10 provided with the first springs 9 at one end slide in the locking grooves 7. In this way, the locking between the fixed disc 6 and the rotating disc 8 is realized according to the movement of the locking blocks 10. Therefore, when the angle is adjusted, the force borne by the supporting mechanism 13 is reduced, so that the device is more convenient to use and more secure when it is protected.

[0031] The fixed seat 2 is provided with two fixed rods 3. The two ends of the fixed rod 3 are movably arranged in the two fixed seats 2 through the rotating columns 4. The rotating column 4 is provided with a torsion spring 11. The torsion spring 11 is connected to the rotating column 4 at one end and connected to the fixed rod 3 at the other end. When the angle of the fixed rod 3 is adjusted, the rotating column 4 rotates, and the torsion spring 11 rotates at the same time. When the torsion spring 11 rotates, the force borne by the torsion spring 11 gradually increases. When the fixed rod 3 is reset, the torsion spring 11 is reset at the same time. Therefore, the parts in the device are more convenient to adjust and reset, and the use convenience of the device is further improved.

[0032] In the embodiment, the supporting mechanism 13 comprises the sliding grooves 12, the supporting frames 14 and the supporting rods 15, one sliding groove 12 is arranged at each end of the fixed rod 3, one supporting frame 14 is slidably arranged in each sliding groove 12, two supporting frames 14 are fixedly arranged on the mounting plate 1 near the sliding grooves 12, two supporting rods 15 are arranged, and each supporting rod 15 is rotatably connected to the supporting frame 14 on the mounting plate 1 and the supporting frame 14 in the corresponding sliding groove 12 at both ends. In work, when the device is inclined at a certain angle, the elastic force between the supporting plate 18 and the elastic assembly 17 can effectively act on the supporting plate 18 at this time, so that the supporting plate 18 can be fully buffered in the process of impact, and when the impact force is large, the pneumatic mechanism 25 controls the supporting frame 14 to slide in the sliding groove 12 at this time, the supporting frame 14 drives the supporting rod 15 to rotate when the supporting frame 14 slides in the sliding groove 12, the angle between the supporting rod 15 and the fixed rod 3 changes at this time, and then the fixed rod 3 gradually becomes vertical, and the supporting plate 18 gradually becomes vertical at the same time when the fixed rod 3 gradually becomes vertical, so as to reduce the impact force of the supporting plate 18, and further improve the impact force of the supporting plate 18, thereby avoiding that the impact force is too large when the device is impacted, and reducing the use safety of the device.

[0033] In the embodiment, the four elastic assemblies 17 are respectively located at the four corners of the fixed plate 16, the elastic assembly 17 comprises the limiting rod 35 and the limiting spring 36, the limiting rod 35 is arranged on the fixed plate 16, the limiting spring 36 is sleeved on the limiting rod 35, the limiting spring 36 is connected to the fixed plate 16 and the supporting plate 18 at both ends, and the outer edges of the fixed plate 16 and the supporting plate 18 are provided with the protective corrugated plate 34. In work, when the supporting plate 18 is impacted, the elastic assembly 17 deforms, so that the buffering force of the elastic assembly 17 acts on the supporting plate 18, and then the device is more safe when impacted, and the object is prevented from impacting on the supporting plate 18, the supporting plate 18 is damaged due to the lack of buffering force, and the service life of the supporting plate 18 is further prolonged.

[0034] In this embodiment, the thrust mechanism 19 includes a rack 20, a second gear 23 and a plurality of sets of push assemblies, each set of push assemblies including a driving shaft 21, a cam 24 and a first gear 22, the driving shaft 21 is rotatably arranged on the fixed plate 16 away from the support plate 18, a plurality of sets of cams 24 are uniformly arranged on each driving shaft 21, a first gear 22 is arranged at both ends of the driving shaft 21, the first gears 22 on the same side of the fixed plate 16 are meshed with each other, and a second gear 23 is arranged on one of the driving shafts 21, one end of the rack 20 is arranged on the support plate 18, and the other end passes through the fixed plate 16 to mesh and connect the second gear 23. When the support plate 18 is subjected to a large impact force, the elastic assembly 17 on the rear side of the support plate 18 deforms, at which time the rack 20 moves, when the rack 20 moves, the rack 20 drives the second gear 23 to rotate, when the second gear 23 rotates, the driving shaft 21 rotates at the same time, at this time, a plurality of first gears 22 rotate, and the cams 24 installed on the driving shaft 21 rotate at the same time, when the cam 24 rotates, the protruding position of the cam 24 extrudes the pneumatic mechanism 25, so that the pneumatic mechanism 25 is opened, thereby increasing the buffering force of the support plate 18, and at the same time, the stability and safety of the equipment when impacted are ensured.

[0035] A limiting groove is formed at one end of the rack 20 away from the support plate 18, a limiting block is arranged on the fixed plate 16, and the limiting block is movably arranged in the limiting groove of the support plate 18. When the rack 20 moves, the limiting block slides in the limiting groove, so that the rack 20 moves more stably, avoiding deviation of the rack 20 during movement, thereby causing the rack 20 to be unable to mesh with the second gear 23, and further improving the movement accuracy of the equipment.

[0036] In this embodiment, the pneumatic mechanism 25 includes a plurality of sets of compression assemblies and cylinder assemblies, the compression assemblies movably pass through the fixed plate 16, one end of the compression assembly is in contact with the cam 24, and the other end is connected to the cylinder assembly, the compression assembly includes a guide rod 37, a second spring 29 and a protruding block 30, the cylinder assembly includes a piston cylinder 26, a piston rod 27, a pressing plate 28 and a resistance plate 33, the guide rod 37 slides through the fixed plate 16, the piston cylinder 26 and the protruding block 30 are arranged at one end of the guide rod 37 close to and away from the support plate 18, the second spring 29 is sleeved on the guide rod 37 and located on the side of the fixed plate 16 close to the support plate 18, the second spring 29 is connected to the bottom of the piston cylinder 26, the piston rod 27 is slidably arranged in the piston cylinder 26, the plurality of piston cylinders 26 are connected to each other through pipelines, the pressing plate 28 is arranged at one end of the piston rod 27 away from the piston cylinder 26, a plurality of resistance plates 33 are uniformly arranged on the support plate 18, the resistance plates 33 are adapted to the positions of the pressing plates 28, and the protruding block 30 is adapted to the position of the cam 24.

[0037] Two of the piston cylinders 26 are provided with a gas pipe 31 at the end of which is provided with a pneumatic rod 32, which is located on the support frame 14 and communicates with the sliding groove 12. In operation, when the pushing mechanism 19 is in operation, the cam 24 rotates and simultaneously presses the protruding block 30, which in turn moves the piston cylinder 26, and the second spring 29 is elongated. When the piston cylinder 26 moves, the resistance plate 33 simultaneously moves towards the piston rod 27. When the resistance plate 33 presses the pressing plate 28 on the piston rod 27, the piston rod 27 moves in the piston cylinder 26. At this time, the resistance between the piston rod 27 and the piston cylinder 26 can be used as the buffer force of the support plate 18. At the same time, the gas flow generated by the piston cylinder 26 and the piston rod 27 enters the pneumatic rod 32 through the gas pipe 31, causing the pneumatic rod 32 to elongate. When the pneumatic rod 32 elongates, the angle of the support mechanism 13 changes, and then the angle of the fixed plate 16 changes, thereby making the support plate 18 gradually vertical. In this way, the impact force on the support plate 18 is buffered, and the impact object on the support plate 18 is quickly separated from the support plate 18, further improving the stability and safety of the support plate 18. When the object on the support plate 18 is separated, the support plate 18 is away from the fixed plate 16, and the cam 24 and the protruding block 30 are away from each other. The force generated by the torsional spring 11 makes the fixed rod 3 reset, thereby making the support mechanism 13 reset, so as to repeat the work, thereby further ensuring the use of the equipment.

[0038] Although the specific embodiments of the application have been described above with reference to the drawings, the description is not a limitation on the scope of protection of the application. Various modifications or variations made by those skilled in the art on the basis of the technical solutions of the application without creative labor are still within the scope of protection of the application.
