Description

Technical Field

[0001] The invention belongs to the technical field of roadbed filling construction, and more specifically, relates to a vibration compaction device and a construction method capable of improving the collapse of the edge of roadbed filling. Background Art

[0002] Roadbed filling refers to the process of piling and compacting qualified soil, stone and other materials to make the roadbed reach the designed height and shape during roadbed construction, thereby providing a solid and stable support foundation for the pavement structure. Among the many tools used for roadbed filling and compaction, the road roller is undoubtedly one of the most commonly used and key equipment.

[0003] Road rollers, also known as earth rollers, are widely used in filling and compaction operations for large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers. Generally, after the soil layer of the road foundation is laid, edge steel channels are installed at the edges to prevent landslides at the edges of the soil layer. When the road roller rolls the edge of the roadbed, the pressure applied will cause the edge steel channels to move, which in turn causes the base and subbase structures at the edge of the soil layer to lose support, causing cracks to appear on the edge of the road, or even collapse. This not only affects the appearance of the road, but also reduces the bearing capacity of the road edge, posing a threat to driving safety.

[0004] After searching, a high fill roadbed compaction device is disclosed in the patent CN218712850U. The application drives the eccentric block to rotate by rotating the rotating rod, and drives the convex block to rotate periodically and press the water bag while vibrating. The water bag supplies water to the hollow pressure plate, and the water flows to the outside through the hollow pressure plate, so that the water bag and the vibration structure work synchronously. When the vibration stops, the water bag also stops flowing to the outside. This device can reduce the porosity between the fillers, making the compaction effect better and the whole process coherent; while vibrating and compacting, the road surface is soaked, which improves work efficiency and solves the problem of loose surface fillers on the surface of the high fill roadbed.

[0005] For another example, in patent CN113605351A, a roadbed intelligent rolling forming device is disclosed. In this application, debris such as stones, plastic bags, ropes, dead branches and leaves inside the roadbed soil layer can be pushed to prevent the rolling roller from directly pressing the debris into the roadbed soil layer, and the multiple guide rotating tubes at the bottom of the special-shaped plate installed in an arc shape will guide the accumulated debris out of the moving path of the rolling roller to prevent the rolling roller from pressing the debris into the roadbed soil layer, thereby ensuring the quality of the roadbed rolled by the rolling roller and improving the working efficiency of the driving vehicle body and the rolling roller.

[0006] The above applications all involve technical improvements to roadbed compaction devices, but the problem of cracks and even collapse at the edge of the roadbed during rolling has not been effectively solved. Summary of the invention

[0007] 1. Problems to be solved

[0022] In some embodiments, a support column is provided in the connection frame for the sliding block to be mounted thereon; and a limiting groove is provided on the support column to cooperate with the limiting block on the sliding block.

[0023] In some embodiments, the limit block is processed with a bevel on one side away from the mounting frame, and the limit block is elastic; when the limit block is subjected to a large extrusion force, it can be deformed and detached from the limit groove to release the lock on the sliding block.

[0024] In some embodiments, a pressure roller assembly is disposed in the second mounting hole on the main support block, and when the rolling roller is away from the edge of the roadbed, the pressure roller assembly temporarily compacts the edge of the roadbed;

[0025] The pressure roller assembly comprises a positioning frame and a pressure wheel rotatably arranged in the positioning frame; wherein,

[0026] A convex block with a first sliding groove is provided on the top of the positioning frame, and a sliding rod connected to the main supporting block is provided in the first sliding groove;

[0027] The first sliding groove is a high-low groove as a whole, and the sliding block drives the positioning frame to move synchronously through the connecting rod, so that the sliding rod slides in the first sliding groove to drive the pressing wheel to move up and down.

[0028] In some embodiments, the connecting rod comprises a first connecting rod and a second connecting rod which are sleeved together and can slide up and down;

[0029] Both ends of the sliding rod are connected to a first fixing block arranged in the second mounting hole;

[0030] The protrusion is provided with a second sliding groove, and the second sliding groove is provided with a sliding frame; the second fixing block in the second mounting hole is located in the sliding frame.

[0035] When the rolling roller deviates to the outside of the road; at this time, the main support block is away from the edge protection channel steel, and the auxiliary support block pops out and squeezes from the outside of the edge protection channel steel to temporarily support the side of the edge protection channel steel;

[0036] When the rolling roller deviates to the inside of the road, the lifting component drives the sliding block to move closer to the rolling roller, so that the main support block always fits with the outer side of the edge protection channel steel, and reduces the damage to the connection point between the lifting component and the installation frame;

[0037] During the sliding process, the sliding block drives the positioning frame to move synchronously through the connecting rod, and finally drives the pressing wheel to press down to temporarily roll the edge of the road soil layer;

[0038] During the rolling process, the rolling pressure and vibration frequency of the rolling roller can be adjusted by changing the actual working quantity and rotation frequency of the eccentric block.

[0039] 3. Beneficial effects

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The present invention provides a vibration compaction device that can improve the collapse of the edge of the roadbed fill. By setting up an edge protection mechanism, the main support block is used to support the side of the edge protection channel steel, which can effectively prevent the collapse of the roadbed edge caused by the force deviation of the edge protection channel steel. At the same time, an auxiliary support block is slidably arranged in the first mounting hole on the main support block. When the rolling roller deviates to the outside of the road, the main support block is separated from the edge protection channel steel. The auxiliary support block pops out from the first mounting hole under the elastic force of the first elastic member, and can temporarily support the edge protection channel steel, thereby effectively ensuring the continuity of the support for the edge protection channel steel and ensuring the support effect.

[0042] (2) The present invention provides a vibratory compaction device that can improve the collapse of the edge of the roadbed fill. By setting a transition component, when the rolling roller deviates to the inside of the road, the lifting component can drive the sliding block to move in the direction close to the rolling roller, while ensuring that the main support block is always in contact with the outer side of the edge channel steel, and can effectively reduce the damage to the connection points between the lifting component and the installation frame and the main support block.

[0043] (3) The present invention provides a vibration compaction device that can improve the collapse of the edge of the roadbed fill. Through the setting of the pressure roller assembly, when the rolling roller deviates to the inside of the road, the sliding of the sliding block will drive the positioning frame to move synchronously through the connecting rod, so that the sliding rod moves in the first sliding groove. When the sliding rod moves to the high groove section in the first sliding groove, it will drive the pressure wheel to press down, thereby temporarily rolling the edge of the road soil layer.

[0044] (4) The present invention provides a vibration compaction device that can improve the collapse of the edge of roadbed fill. By adjusting the setting of the components, the actual working quantity and rotation frequency of the eccentric block can be changed to adjust the rolling pressure and vibration frequency of the rolling roller to meet the compaction requirements of soil layers with different characteristics.

DETAILED DESCRIPTION

[0059] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0060] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0061] As mentioned in the background technology, the existing roadbed compaction device lacks effective support for the edge guard channel steel, which leads to cracks and even collapse when rolling the edge of the roadbed. In the prior art, inclined supports are usually added to the outside of the edge guard channel steel to overcome the outward extrusion force on the edge guard channel steel to prevent the edge guard channel steel from shifting. However, in the actual construction process, in order to facilitate the removal of the inclined supports in the later stage, the support points of the inclined supports will not be reinforced with concrete. Therefore, the inclined supports lack stable force points, which greatly reduces the supporting force of the edge guard channel steel, and it is difficult to completely ensure that the edge guard channel steel does not shift.

[0062] In order to solve the problem that the inclined support lacks a stable stress point and cannot provide stable support for the edge channel steel alone, the optimization solution that can be thought of is to fix the support plate directly on the roller, so as to form a stable stress point for supporting the side of the edge channel steel. However, since the road surface to be compacted cannot be an ideal straight line, but has some bends; and the roller will also deviate during the actual driving process, the position of the support plate will constantly change, which may easily lead to the separation between the support plate and the edge channel steel, and lose the original support effect. Therefore, this solution cannot be applied in actual construction.

[0063] The present invention provides a vibration compaction device and a construction method for improving the collapse of the edge of roadbed fill, aiming to solve the problem that when the rolling roller is compacting the edge of the roadbed, the edge protection channel steel cannot be stably supported, which makes the edge protection channel steel easily deviate and causes the collapse of the roadbed edge; at the same time, it is ensured that when the driving direction of the roller deviates, the edge protection channel steel can still provide a stable support effect.

[0064] The present invention is further described below in conjunction with specific embodiments.

[0065] like Figure 1 As shown, a vibration compaction device for improving the edge collapse of roadbed fill in this embodiment includes a road roller and an edge protection mechanism 200. The road roller has a structure that is basically consistent with the prior art, and mainly includes a road roller body 100, a mounting frame 110 disposed at the front of the road roller body 100, and a rolling roller 120 installed in the mounting frame 110. A camera 130 can be added to the front of the mounting frame 110 to facilitate the driver to monitor the road surface conditions in real time.

[0066] The edge protection mechanism 200 is installed on the mounting frame 110 and is used to provide lateral support for the edge protection channel steel at the edge of the roadbed to prevent the pressure exerted by the rolling roller 120 when rolling the edge of the roadbed from causing the edge protection channel steel to move, thereby causing the base layer and sub-base structure at the edge of the soil layer to lose support and collapse.

[0067] Specifically, refer to Figure 2 As shown, the edge protection mechanism 200 includes a side support component 220 and a lifting component 210 for driving the side support component 220 to move up and down. The lifting component 210 is arranged on the side wall of the mounting frame 110 and is located on one side of the axial direction of the rolling roller 120. The lifting component 210 can adopt existing technology, for example, a cylinder, an oil cylinder, an electric push rod or other structures that can drive the side support component 220 to move up and down.

[0068] like Figure 6As shown, the side support component 220 includes a main support block 221 connected to the output end of the lifting component 210, and a receiving space for the edge channel steel to be inserted is formed between the main support block 221 and the end of the rolling roller 120. When the rolling roller 120 rolls the edge of the roadbed, the lifting component 210 drives the main support block 221 to descend and support the edge channel steel from the outside to prevent the collapse of the roadbed edge due to the force deviation of the edge channel steel.

[0069] Furthermore, a first mounting hole 2211 is provided on the main support block 221, and an auxiliary support block 222 is slidably provided in the first mounting hole 2211, and the auxiliary support block 222 is connected to a first elastic member 223. When the main support block 221 works normally, the auxiliary support block 222 is compressed into the first mounting hole 2211. At this time, the main support block 221 is close to the outer side of the edge protection channel steel, thereby providing a larger support surface.

[0070] When the device is moving, due to road surface reasons or driving reasons, the rolling roller 120 deviates to the outside of the roadbed. As the rolling roller 120 continues to deviate outward, the main support block 221 will gradually separate from the edge guard channel steel, thereby losing its supporting effect. At this time, the auxiliary support block 222 pops out from the first mounting hole 2211 under the action of the first elastic member 223, and temporarily supports the edge guard channel steel. Thereby, the risk of the edge guard channel steel moving during the time when the main support block 221 loses its supporting effect can be avoided. When the rolling position of the rolling roller 120 returns to normal, the auxiliary support block 222 is compressed into the first mounting hole 2211, and the main support block 221 provides support for the edge guard channel steel.

[0071] Specifically in this embodiment, Figure 6 The first mounting hole 2211 is a through hole, and two through holes are provided on the left and right sides. A positioning plate 224 is provided on the side of the main support block 221 away from the mounting frame 110 and located at the position of the first mounting hole 2211. At the same time, a guide rod 225 and a positioning rod 226 are provided on the side of the auxiliary support block 222 facing the positioning plate 224. Among them, the first elastic member 223 is sleeved on the positioning rod 226 and is limited between the positioning plate 224 and the stop block at the end of the positioning rod 226.

[0072] Preferably, two guide rods 225 are arranged one above the other, and the positioning rod 226 is located between the two guide rods 225. Of course, guide holes for the guide rods 225 and the positioning rods 226 to pass freely need to be provided at corresponding positions on the positioning plate 224.

[0073] In some embodiments, when the device is moving, the rolling roller 120 is offset to the inside of the roadbed due to road surface problems or driving. At this time, the edge channel steel has a stopping effect on the main support block 221, thereby limiting the smooth movement of the rolling roller 120. At the same time, the main support block 221 will be subjected to a greater reverse extrusion force, which can easily accelerate the damage to the connection point between the lifting component 210 and the mounting frame 110 and the main support block 221, and even cause the connection point to break. For this reason, in this embodiment, a transition component 230 is provided between the lifting component 210 and the main support block 221 to reduce the problem of damage to the connection point caused by excessive extrusion strength.

[0074] Specifically, refer to Figure 7 As shown, the transition component 230 includes a connection frame 231 and a sliding block 232 slidably arranged in the connection frame 231. The connection frame 231 is arranged on the top of the main support block 221; the output end of the lifting component 210 is connected to the top of the sliding block 232. At the same time, the sliding block 232 is connected to the second elastic member 235. When the device deviates to the inner side of the roadbed, the lifting component 210 can drive the sliding block 232 to slide in the connection frame 231 toward the installation frame 110, thereby effectively reducing the excessive reaction force on the main support block 221. When the device returns to the normal position, the sliding block 232 returns to its original position under the action of the second elastic member 235, and thus will not affect the supporting effect of the main support block 221 on the edge channel steel.

[0075] Furthermore, a support column 233 is provided in the connection frame 231, and the sliding block 232 is sleeved on the support column 233 to increase the stability of the sliding block 232 during the sliding process. At the same time, the second elastic member 235 is also sleeved on the support column 233 and is limited between the sliding block 232 and the inner wall of the connection frame 231 near the end of the mounting frame 110.

[0076] like Figure 4 As shown, in some embodiments, a series of limiting grooves 2331 are provided at intervals on the upper surface of the support column 233 along its length direction (i.e., the sliding direction of the sliding block 232). At the same time, a limiting block 234 that can be engaged with the limiting groove 2331 is provided on the side of the sliding block 232 to ensure the stability of the main support block 221 supporting the edge protection channel steel.

[0077] Of course, the engagement between the above-mentioned limit block 234 and the limit groove 2331, on the one hand, needs to ensure that when the rolling roller 120 is rolling normally at the edge, it plays a role in limiting the sliding block 232; on the other hand, when the device deviates to the inner side of the roadbed, the sliding block 232 can be smoothly moved and reset so that the main support block 221 maintains its original position. For this reason, in this embodiment, the limit block 234 is made of an elastic material, such as spring steel, stainless steel elastic material, or alloy material, etc., which are not listed here one by one. At the same time, a bevel is processed on the side of the limit block 234 away from the mounting frame 110. Of course, the limit groove 2331 also needs to be processed with a matching bevel.

[0078] When the device is offset, the force applied to the limit block 234 is relatively large, so that the limit block 234 is squeezed and deformed in the limit slot 2331, thereby detaching from the limit slot 2331, and realizing the movement of the sliding block 232. When the limit block 234 is reset under the force of the second elastic member 235, at this time, although the force applied by the second elastic member 235 is much smaller than the driving force generated when the device is offset, the limit block 234 can also detach from the limit slot 2331 due to the setting of the inclined surface.

[0079] In some embodiments, an oblique support may be added to the outer side of the edge channel steel, and the main support block 221 will interfere with the oblique support during the movement of the roller body 100. To this end, in this embodiment, the output end of the lifting component 210 is hinged to the sliding block 232, and a notch 2213 is provided at the bottom of the main support block 221 near the middle. When the main support block 221 moves to the oblique support, the lifting component 210 is first used to drive the main support block 221 to move upward; when the notch 2213 is stuck at the top of the oblique support, the main support block 221 will adaptively tilt along the hinge point, thereby avoiding the main support block 221 from getting stuck. In addition, in order to ensure the stability of the support of the auxiliary support block 222, a first mounting hole 2211 is provided on each of the main support blocks 221 on both sides of the notch 2213, and an auxiliary support block 222 is provided in each first mounting hole 2211.

[0080] The present embodiment is a vibration compaction device that can improve the collapse of the edge of the roadbed fill. Through the arrangement of the main support block 221 and the auxiliary support block 222, it can ensure that the rolling roller 120 can always effectively support the edge channel steel when it is offset. However, when the rolling roller 120 deviates to the inside of the road surface, the edge of the roadbed will no longer be rolled, resulting in insufficient compaction of this part of the roadbed, leaving quality defects. For this reason, in the present embodiment, a second mounting hole 2212 is also opened on the main support block 221, and a pressure roller assembly 240 is arranged in the second mounting hole 2212. When the rolling roller 120 is away from the edge of the roadbed, the pressure roller assembly 240 temporarily compacts the edge of the roadbed.

[0081] refer to Figure 3 , Figure 8 As shown, the second mounting hole 2212 is opened above the first mounting hole 2211. The pressure roller assembly 240 includes a positioning frame 241 and a pressure wheel 242. The positioning frame 241 is a U-shaped frame as a whole, and the pressure wheel 242 is rotatably connected to the U-shaped frame through a rotating shaft. A protrusion 244 is provided on the top of the positioning frame 241, and a first sliding groove 2441 is provided on the protrusion 244. The first sliding groove 2441 is a high-low groove as a whole, which includes a high groove section, a low groove section and a transition section connecting the high and low groove sections.

[0082] A sliding rod 245 connected to the main support block 221 is disposed in the first sliding groove 2441. At the same time, the positioning frame 241 is connected to the sliding block 232 through the connecting rod 243. When the sliding block 232 moves, the positioning frame 241 can be driven to move through the connecting rod 243, so that the sliding rod 245 and the high and low groove sections of the first sliding groove 2441 are alternately matched to realize the lifting and lowering of the positioning frame 241, thereby driving the pressing wheel 242 to lift and lower.

[0083] Specifically in this embodiment, the first sliding groove 2441 is formed on the side wall of the protrusion 244 and is a through groove. Both ends of the sliding rod 245 extending out of the first sliding groove 2441 are connected to the first fixing block 246, and the top of the first fixing block 246 is connected to the inner top wall of the second mounting hole 2212.

[0084] The connecting rod 243 includes a first connecting rod 2431 and a second connecting rod 2432 which are mutually sleeved and can slide up and down. The first connecting rod 2431 and the second connecting rod 2432 are both L-shaped structures as a whole. One end of the first connecting rod 2431 passes through the connecting frame 231 and is connected to the sliding block 232, and the other end is inserted into the socket of the second connecting rod 2432 and can be freely raised and lowered; and the other end of the second connecting rod 2432 is connected to the positioning frame 241. Through the mutual cooperation of the first connecting rod 2431 and the second connecting rod 2432, the sliding block 232 can drive the positioning frame 241 to move horizontally without hindering the upward and downward movement of the positioning frame 241.

[0085] like Figure 5 As shown, in some embodiments, a second sliding groove 2442 is further provided at the top of the protrusion 244, and a sliding frame 247 is slidably provided in the second sliding groove 2442. A second fixing block 248 is provided in the sliding frame 247, and the top of the second fixing block 248 is connected to the inner top wall of the second mounting hole 2212. The cooperation between the second fixing block 248 and the sliding frame 247 can further ensure the stability of the positioning frame 241 during the movement.

[0086] In some embodiments, the rolling roller 120 is also connected to an adjustment component for adjusting the rolling pressure and vibration frequency of the rolling roller 120 to meet the vibration compaction requirements of soil layers with different characteristics.

[0087] Specifically, refer to Fig. 9 As shown, the adjustment component includes a support shaft 140 disposed in the rolling roller 120, and the support shaft 140 is provided with a plurality of eccentric blocks 150 spaced along its axial direction, and each eccentric block 150 is equipped with its own driving source 160. Among them, both the driving source 160 and the eccentric block 150 can be sleeved on the support shaft 140. Preferably, the driving source 160 is a hollow motor, and the output end of the hollow motor is connected to the eccentric block 150. The eccentric block 150 is driven to rotate by the hollow motor. When the eccentric block 150 rotates, the rolling roller 120 can vibrate, and then the rolling roller 120 can apply sufficient pressure to the ground. At the same time, the number of rotations of the eccentric block 150 can be controlled according to the pressure required to be applied to the ground, so that the pressure generated by the rolling roller 120 can be adjusted. In addition, the vibration frequency of the rolling roller 120 can be adjusted by controlling the rotation speed of the hollow motor.

[0088] Specifically in this embodiment, the eccentric block 150 and the driving source 160 are each provided with five. Fig. 9 The paper direction is based on the eccentric blocks 150 from left to right, which are No. 1, No. 2, No. 3, No. 4, and No. 5. The eccentric blocks 150 of No. 1-5 can automatically adjust different vibration frequencies and pressures according to the gradation characteristics of the pavement material. The specific working states are as follows:

[0089] State 1: For daily use, the eccentric blocks 1, 3, and 5 rotate 150 degrees, and the rolling pressure is relatively uniform, which is suitable for compacting most soil layers;

[0090] State 2: The eccentric blocks 2 and 4 rotate 150 degrees, which is suitable for scenes with soft soil.

[0091] State three, all eccentric blocks 150 rotate together, which is suitable for hard soil layers;

[0092] State 4, eccentric blocks No. 1 and No. 5 rotate 150 degrees, which is suitable for compacting the edge of the road foundation soil layer;

[0093] According to the above four states, it is divided into normal state, pressure reduction, pressure increase, and special edge position pressure, so as to adapt to the pressure that needs to be applied for soil compaction most of the time. Among them, the drive source 160 and its control module are both existing technologies. For example, the drive source 160 can be selected as a Y series hollow shaft motor, which is a relatively common three-phase asynchronous motor with the advantages of high efficiency, energy saving, low noise, and low vibration. There is a hollow shaft in the center, which is convenient for connecting with the eccentric block 150 to achieve stable rotation of the eccentric block 150. The control module model can be Siemens S7-200SMART: This is a small PLC controller with a rich instruction set and powerful communication functions.

[0094] The specific construction method of a vibration compaction device of this embodiment that can improve the collapse of the edge of the roadbed fill is as follows:

[0095] First, clear away debris, garbage, and loose soil in the construction site. For newly built roads, stake out the center and side lines of the road according to design requirements and set leveling points to provide a benchmark for subsequent construction.

[0096] When rolling the road soil layer, the road condition is monitored by the camera 130, and the vibration pressure of the rolling roller 120 is adaptively adjusted by the adjustment component.

[0097] When rolling the edge of the soil layer, the edge protection channel steel of the road surface is supported and positioned by the edge protection mechanism 200, specifically:

[0098] When the rolling roller 120 is rolling the edge of the road soil layer, the main support block 221 will contact the roadside channel steel, so that the main support block 221 can support the channel steel, thereby preventing the pressure applied by the rolling roller 120 from causing the channel steel to move, thereby causing the edge of the road soil layer to lose support. At the same time, as the rolling roller 120 moves, the main support block 221 can continuously support the channel steel.

[0099] When the main support block 221 is close to the oblique support of the edge protection channel steel, the main support block 221 is driven to move upward by the lifting component 210; thus, when the main support block 221 contacts the oblique support, the main support block 221 can move upward, and the bottom notch 2213 of the main support block 221 is stuck on the top of the oblique support; and as the rolling roller 120 moves, the main support block 221 will tilt adaptively to avoid the main support block 221 from getting stuck. When the main support block 221 tilts at a certain angle, it can drive the main support block 221 to move upward, so that the bottom notch 2213 of the main support block 221 is separated from the oblique support; after crossing the oblique support, the main support block 221 is driven to reset downward.

[0100] When the device is in motion, due to improper driving by the driver or road conditions, the rolling roller 120 deviates to the outside of the road; as the rolling roller 120 deviates outward, the main support block 221 will separate from the edge guard channel steel. At this time, the auxiliary support block 222 is pushed out and contacts the edge guard channel steel through the first elastic member 223, so as to temporarily support the edge guard channel steel, thereby avoiding the edge guard channel steel from being displaced due to loss of support during the period when the main support block 221 is separated from the edge guard channel steel.

[0101] When the device is in motion, if the rolling roller 120 deviates to the inside of the road due to improper driving by the driver or road surface problems, the main support block 221 cannot move due to the blockage of the edge protection channel steel, so the sliding block 232 will move in the connecting frame 231, so that the main support block 221 can always be kept in the current position and continue to support the edge protection channel steel.

[0102] At the same time, since the rolling roller 120 is offset to the inside of the road, it is unable to roll the edge of the road soil layer. When the sliding block 232 moves, it will drive the positioning frame 241 to move through the connecting rod 243; when the positioning frame 241 moves, it will cause the sliding rod 245 to enter the high groove section from the low groove section of the first sliding groove 2441; at this time, the positioning frame 241 will move downward under the cooperation of the two, and drive the pressure wheel 242 to move downward, so that the pressure wheel 242 can contact the top of the edge of the road soil layer and generate pressure on the top of the edge of the road soil layer. In this way, the edge of the road soil layer can be temporarily rolled to flatten the raised soil on the surface of the edge of the road soil layer, so as to avoid the situation where the edge of the road soil layer is leaking when the rolling roller 120 is offset to the inside of the road.

[0103] It should be noted that when the driver finds that the rolling roller 120 is offset, he will quickly adjust the rolling roller 120, thereby avoiding the situation where the pressure wheel 242 is used for too long, resulting in the edge of the road soil layer not being fully rolled. Of course, technology can also be used to monitor the offset of the rolling roller 120 and alarm. For example, a position sensor is provided on the mounting frame 110, and a buzzer is equipped to prompt the operator to make timely adjustments.

[0104] The present embodiment is a vibration compaction device that can improve the collapse of the edge of the roadbed fill. By setting the edge protection mechanism 200, the alternating support of the main support block 221 and the auxiliary support block 222 can effectively ensure the continuity of the support of the edge protection channel steel and the support effect. At the same time, when the rolling roller 120 is unable to roll the edge of the soil layer due to deviation, the edge of the road soil layer can be temporarily rolled by the roller assembly 240, thereby effectively avoiding the risk of the edge of the road soil layer being missed due to the inward movement of the rolling roller 120.

[0105] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
