Description

Technical Field

[0001] The utility model relates to the technical field of roadbed slope protection, in particular to a roadbed slope protection device. Background Art

[0002] Roadbed refers to the structure that directly supports the track formed by filling or excavation in civil engineering, also known as the line substructure. Roadbed slope refers to the inclined surface connecting the ground to both sides of the roadbed cross section in transportation projects such as roads or railways. The design and construction of roadbed slopes are crucial to the stability and safety of roads. According to different terrains and engineering requirements, roadbed slopes can be divided into embankment slopes and cutting slopes.

[0003] The utility model patent with authorization announcement number: CN215714737U discloses a roadbed slope protection device, involving a base plate, a positioning box is fixedly connected to the top of the base plate, a vertical plate is slidably connected to the inner cavity of the positioning box, the top of the vertical plate passes through the positioning box and extends to the outside of the positioning box, a compression spring is evenly fixedly connected to the right side of the vertical plate and located on the outside of the positioning box, a baffle is fixedly connected to the right side of the compression spring, and threaded holes are evenly opened at the front and rear positions of the left side of the vertical plate and located in the inner cavity of the positioning box. The utility model can conveniently block and protect the gravel splashed by sliding down the slope by arranging the vertical plate, the threaded holes and the limit bolts can be conveniently adjusted to the installation position of the vertical plate, so as to ensure the flatness and beauty between adjacent vertical plates. By arranging the above structure, the protective device has the advantage of being easy to use when in use, and solves the problem that the original protective device is inconvenient to use when in use, thereby avoiding waste of resources.

[0004] Regarding the above scheme: the reference document connects the bottom plate to the ground or the soil of the roadbed slope through steel nails, and uses compression springs to buffer and block the rolling stones and soil, thereby reducing the obstruction and damage caused by the soil and stones on the roadbed slope to the fall. However, the steel nails are small in size and the contact area between them and the soil is not large, so the friction between the steel nails and the soil is also small. This makes it easy for the baffle and the compression spring to tilt or fall when blocking larger stones or more soil due to the poor connection and limiting effect of the steel nails.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0027] In addition, the second baffle 25 can block mud and stones through the elasticity of the buffer spring 23 and the telescopic effect of the damper 24. At the same time, the damper 24 can effectively limit the buffer spring 23 while playing a buffering role, so that the elasticity of the buffer spring 23 can smoothly play a buffering role and is not prone to violent shaking due to elasticity. The rubber protective layer 26 can play a buffering role while shielding the second baffle 25 to a certain extent, so that the second baffle 25 is not easily damaged when hit by mud or stones. The steel nails 3 can smoothly connect the bottom plate 1 to the upper side of the ground or soil. The setting of the reinforcement mechanism 4 can effectively increase the stability of the connection between the bottom plate 1 and the soil, and reduce the possibility of the bottom plate 1 falling when blocking mud and stones. The auxiliary mechanism 5 can further block and limit some stones and mud, thereby improving the blocking effect of mud and stones.

[0028] See also Figure 1-6 The reinforcement mechanism 4 includes a reinforcement block 41 connected to the inner side of the bottom plate 1, a bidirectional screw 42 and a limit rod 43 are connected to the inner side of the reinforcement block 41, and both ends of the bidirectional screw 42 pass through the reinforcement block 41, and the outer side of the bidirectional screw 42 is connected to a first plug block 441 and a second plug block 442, and the first plug block 441 and the second plug block 442 are both connected to the outer side of the limit rod 43, and a hollow groove 45 is provided on the outer side of the reinforcement block 41, and the hollow groove 45 has two, the first plug block 441 and the second plug block 442 are respectively provided. The reinforcing block 41 is respectively arranged on the inner side of the two hollow grooves 45, and the two-way screw 42 has opposite threads on both sides. The two-way screw 42 can also connect the first plug block 441 and the second plug block 442, and the limit rod 43 can limit the first plug block 441 and the second plug block 442, so that when the two-way screw 42 rotates, it can smoothly drive the first plug block 441 and the second plug block 442 to move in opposite directions;

[0029] In addition, when the reinforcement block 41 is inserted into the soil, it can increase the stability of the connection between the base plate 1 and the soil, and increase the contact area with the soil due to its larger volume, thereby increasing the friction with the soil. When the first plug block 441 and the second plug block 442 extend from the hollow groove 45 and are inserted into the soil, they can increase the connection area between the reinforcement block 41 and the soil, and at the same time further improve the stability of the reinforcement block 41 and the base plate 1, thereby reducing the possibility of the base plate 1 falling down during use.

[0030] See also Figure 1-5The auxiliary mechanism 5 includes a fixed plate 51 connected to one side of the bottom plate 1, and a first mounting groove 521 and a second mounting groove 522 are opened on the upper side of the fixed plate 51. The fixed plate 51 is located on the inner side of the first mounting groove 521 and is connected to a rotating rod 53, and both ends of the rotating rod 53 pass through the inner side of the second mounting groove 522. The outer side of the rotating rod 53 is connected to a third baffle plate 54, and one end of the rotating rod 53 is connected to a gear 55, and the gear 55 is arranged on the inner side of the second mounting groove 522. The fixed plate 51 is located on the inner side of the second mounting groove 522 and is connected to a rack 56, and the rack 56 is meshed with the gear 55. The fixed plate 51 can be connected to the rotating rod 53 through the first mounting groove 521, and the rotating rod 53 can be connected to the fixed plate 51 through the first mounting groove 521. The movable rod 53 can be used to install the third baffle plate 54. When the rotating rod 53 is rotating, it can smoothly drive the third baffle plate 54 to rotate together. After the third baffle plate 54 is rotated to a certain angle, it can be in an inclined state, and the third baffle plate 54 in the inclined state can limit and block mud and stones. The rotating rod 53 can also play a role in installing and fixing the gear 55, and the rack 56 connected to the fixed plate 51 through the second mounting groove 522 can drive the rotating rod 53 to rotate through the engagement between itself and the gear 55, so that when the third baffle plate 54 needs to be rotated, it can be rotated by moving the rack 56.

[0031] It should be noted that when the third baffle plate 54 is rotated by the rotation of the rotating rod 53, the rotation angle of the third baffle plate 54 needs to be less than ninety degrees, so that the third baffle plate 54 can face one side of the slope, and when mud or stones roll down, the third baffle plate 54 can limit and jam them. If the rotation angle of the third baffle plate 54 exceeds ninety degrees, when there is a lot of mud, the mud may slide more smoothly to one side of the base plate 1 through the inclination of the third baffle plate 54, thereby increasing the amount of mud and stones that need to be limited by the base plate 1, and increasing the load of the base plate 1 when limiting and blocking stones and mud.

The two soil insertion blocks 6 are respectively arranged on the lower sides of the first insertion block 441 and the second insertion block 442. The reinforcement block 41 can play a role in installing and fixing the soil insertion block 6, and the setting of the soil insertion block 6 can make it easier for the reinforcement block 41 to be inserted into the interior of the soil, and it is not easy to cause a large resistance when the reinforcement block 41 is moved down and installed due to the first insertion block 441 and the second insertion block 442.

[0035] See also Figure 4 : A support plate 81 is connected to one side of the first baffle plate 22, a connecting ring block 82 is connected to one side of the support plate 81, a fixed bottom block 83 is connected to the outer side of the connecting ring block 82, a third threaded groove 84 is provided on the upper side of the fixed bottom block 83, the first baffle plate 22 can be connected to the connecting ring block 82 through the support plate 81, and the connecting ring block 82 can be connected to the fixed bottom block 83, the fixed bottom block 83 can be connected to the ground by the staff using tools such as bolts through the third threaded groove 84, so that the fixed bottom block 83 can smoothly pass through the support plate 81 to further limit and support the first baffle plate 22, thereby increasing the stability of the first baffle plate 22 when in use.

The protective block 7 can shield and protect the rack 56 and the gear 55, thereby preventing the rack 56 and the gear 55 from being damaged by falling mud, sand or stones.

[0037] See also Figure 3 and Figure 6 : A fixing rod 10 is connected to the inner side of the reinforcement block 41, and both ends of the bidirectional screw 42 are connected to a rotating block 9, and the rotating block 9 is hexagonal. The setting of the fixing rod 10 makes it more convenient and easy for the staff to rotate the reinforcement block 41, and the shape of the rotating block 9 is similar to a nut, so when the staff needs to rotate the bidirectional screw 42, if the bidirectional screw 42 cannot be easily rotated due to hard soil, the staff can use a wrench to rotate the rotating block 9, and rotate the bidirectional screw 42 through the rotating block 9, thereby realizing the movement of the first plug block 441 and the second plug block 442.

Then the staff can rotate the reinforcement block 41 to move and insert the reinforcement block 41 to the inside of the soil. After the reinforcement block 41 is inserted, the staff can rotate the bidirectional screw 42. Through the rotation of the bidirectional screw 42, the first plug block 441 and the second plug block 442 are driven to move out from the inside of the reinforcement block 41 and smoothly inserted into the inside of the soil, thereby increasing the stability between the reinforcement block 41 and the base plate 1. Then, the fixed base block 83 is connected to the ground or soil. When connecting, the bolts can be connected through the third threaded groove 84.

[0040] After that, the staff can connect the fixed plate 51 with the reinforcement block 41, and move the rack 56 after connection. Through the meshing between the rack 56 and the gear 55, the rotating rod 53 and the third baffle 54 are driven to rotate, so that the third baffle 54 rises and rotates.
