Description

Technical Field

[0001] This invention relates to the field of road construction, and in particular to a device for repairing the slope of a high embankment. Background Technology

[0002] High embankments are the supporting structure of embankments. They are constructed using a layered filling and compaction method, but the fill material for each layer varies. Furthermore, slope protection is a highly dangerous geotechnical engineering project, making slope trimming particularly important. Due to the high slope height of high embankments, to ensure stability, the slope is typically constructed in a stepped shape to facilitate excavator access and compaction. However, this method is inefficient, increases the slope area, occupies significant amounts of farmland and forest land, and increases the overall construction workload. Therefore, a slope trimming device suitable for high embankments is needed to assist in slope compaction and ensure embankment safety. Summary of the Invention

[0003] The purpose of this invention is to provide a slope trimming device for high embankment roads. This slope trimming device can conveniently compact the slope to ensure the safety of the embankment, while also shortening the embankment construction time and improving the efficiency of embankment construction.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A slope trimming device for high embankments includes a transport vehicle, a crane, and a slope trimming device. The crane is vertically and retractably mounted on the transport vehicle. The slope trimming device is connected to the crane. The slope trimming device includes a portal frame with travel wheels on both sides for movement on the slope. A trimming mechanism is installed inside the travel frame. A rotatable support shaft is mounted on the top of the travel frame. Three sets of cable rollers and one wire roller are sequentially mounted on the support shaft. Steel cables are wound around the three sets of cable rollers. The steel cable on the middle cable roller is... The cable has the opposite exit direction to the steel cable on the two side cable rollers. The steel cable on the middle cable roller is connected to the hanger. The extended ends of the steel cables on the two side cable rollers are connected to fixing nails installed at the foot of the slope. A power line is wound on the cable roller, and the exit direction of the power line is the same as that of the steel cable on the middle cable roller. A conductive slip ring is installed on the side wall of the cable roller, and a power supply socket is connected to the conductive slip ring. A motor that drives the support shaft to rotate is installed on the traveling frame.

[0006] The trimming mechanism includes a support frame with multiple vertical support columns. Each support column is fitted with a detachable counterweight. A rammer is vertically installed in the middle of the support frame. A rammer plate that contacts the slope is installed below the rammer via a ball joint. All four sides of the rammer plate are machined with upward-curved arc-shaped chamfers.

[0007] The walking frame is equipped with two sets of adjustment components for adjusting the angle of the tamping plate. The two sets of adjustment components are perpendicular to each other. Each adjustment component includes two rotating shafts and at least one elastic adjustment rope wound around the two rotating shafts. The two ends of the elastic adjustment rope are fixed to the two ends of the tamping plate. A servo motor is installed on the walking frame to drive one of the rotating shafts to rotate. A tensioner is installed on the walking frame between the two rotating shafts to tighten the elastic adjustment rope.

[0008] The walking frame has a clearance opening in the middle that is larger than the support frame. Part of the support frame passes through the clearance opening and is positioned above the walking frame. Multiple inclined support springs are installed in the clearance opening and connected to the support frame.

[0009] The walking frame surfaces on both sides of the clearance opening are fitted with sleeves for steel cables to pass through. The sleeves are fixed to the walking frame surface, and a guide ring is installed on the walking frame surface at the end of the sleeve away from the cable roller to prevent the steel cable from swaying.

[0010] The traveling wheels are four in number and are mounted at the four corners of the traveling frame via a liftable suspension device.

[0011] The beneficial effects of the high-fill embankment slope trimming device provided by this invention are:

[0012] (1) By installing a gantry on the transport vehicle, the gantry can support the slope repair device, which can easily repair the slope of the high embankment. At the same time, under the action of the walking frame, the repair mechanism and the support shaft, cable roller and motor installed on the walking frame, the slope repair device does not need to be operated manually on the slope, which can greatly improve the slope repair efficiency and ensure the safety of workers.

[0013] (2) By installing three cable rollers on the support shaft, with the cable roller in the middle having the opposite cable output direction to the adjacent rollers, the height of the walking frame on the slope can be driven by the motor after the length of the three cable rollers on the walking frame is fixed, so that the trimming mechanism can easily trim the slope to ensure the stability of the slope.

[0014] (3) By installing counterweights on the support frame, the weight of the rammer can be increased, thereby ensuring the compaction effect of the slope and improving the efficiency of slope trimming. In addition, the flatness of the slope can be improved under the action of the counterweights when the slope is leveled.

[0015] (4) By installing a rammer in the support frame, the slope can be compacted conveniently. At the same time, the rammer is connected to a rammer plate, which can be adjusted according to the slope inclination under the action of the adjustment component, thereby ensuring the rammering effect on the slope.

Detailed Implementation

[0021] Example

[0022] like Figures 1-3As shown, the high embankment slope trimming device provided in this embodiment includes a transport vehicle 1, a crane 2, and a slope trimming device. The crane 2 is vertically and retractably mounted on the transport vehicle 1. The transport vehicle 1 facilitates the movement of the slope trimming device. Since it is designed for embankments, whose slopes are below the road surface, the retractable crane 2 allows for easy adjustment of the working height of the slope trimming device to handle slope trimming operations with various slopes and terrains. The slope trimming device is connected to the crane 2 and includes a portal frame 3. The portal frame 3 has travel wheels 35 installed on both sides for movement on the slope. A trimming mechanism 4 is installed inside the portal frame 3, and a trimming device is installed on the top of the portal frame 3. A rotatable support shaft 5 is provided, on which three sets of cable rollers 51 and one wire roller 53 are sequentially mounted. Each of the three cable rollers 51 has a steel cable 52 wound around it. The steel cable 52 on the middle cable roller 51 has the opposite output direction to the steel cable 52 on the two side cable rollers 51. The steel cable 52 on the middle cable roller 51 is connected to the hanger 2, while the extended ends of the steel cables 52 on the two side cable rollers 51 are connected to fixing nails installed at the foot of the slope. With this design, when the support shaft 5 rotates, the rollers on the different cable rollers 51 will perform wire winding or unwinding operations, thereby allowing the traveling frame 3 to move along the output direction of the steel cable 52. When in use, the fixing nails are fixed to the foot of the slope, and together with the transport vehicle 1 on the top of the slope, the slope trimming mechanism 4 can be easily controlled to move on the slope, thereby realizing the slope trimming operation. The power cable 54 is wound on the wire roller 53. The exit direction of the power cable 54 is the same as the exit direction of the steel cable 52 on the middle cable roller 51. This exit design allows the power cable 54 to follow the layout of the traveling frame 3, and there will be no situation where the power cable 54 is pressed or tangled by the traveling wheel 35. It can easily provide working power for the slope trimming device. The power supplied by the power cable can be provided by the generator car or by the transport vehicle 1. At the same time, the side of the wire roller 53 A conductive slip ring 55 is installed on the wall. The conductive slip ring 55 is a device in an electromechanical system that can transmit power and signals from a fixed position to a rotating position while rotating continuously. This is existing technology and will not be described in detail here. The conductive slip ring 55 is connected to a power socket 56, which can conveniently provide the power required for the operation of the trimming mechanism 4. The walking frame 3 is equipped with a motor 57 that drives the support shaft 5 to rotate. The motor 57 serves as the driving mechanism for the movement of the walking frame 3. Through forward and reverse rotation and the cooperation of three sets of cable rollers 51, the slope trimming device can be moved to the place where the slope needs to be trimmed, thereby eliminating the need for manual operation on the slope, such as operating an excavator to trim the slope.

[0023] In order to ensure stable slope repair operations, such as Figure 3As shown, the trimming mechanism 4 includes a support frame 41, on which multiple vertical support columns 42 are provided. A detachable counterweight 43 is fitted on each support column 42. A rammer 44 is vertically installed in the middle of the support frame 41. The counterweight 43 can increase the weight of the trimming mechanism 4. Under the action of the rammer 44, the efficiency of slope trimming can be improved. A rammer plate 45 that contacts the slope is installed below the rammer 44 through a ball joint. The four sides of the rammer plate 45 are processed with upward-curved arc chamfers. The arc chamfers can reduce the friction between the rammer plate 45 and the slope when the slope is leveled, thereby improving the trimming efficiency of the slope trimming device.

[0024] To adapt to uneven slopes, such as Figure 3 As shown, the walking frame 3 is equipped with two sets of adjustment components 6 for adjusting the angle of the tamping plate 45. The two sets of adjustment components 6 are perpendicular to each other. Each adjustment component 6 includes two rotating shafts 61 and at least one elastic adjustment rope 62 wound around the two rotating shafts 61. The two ends of the elastic adjustment rope 62 are fixed to the two ends of the tamping plate 45. The walking frame 3 is equipped with a servo motor 63 that drives one of the rotating shafts 61 to rotate. There are two elastic adjustment ropes 62, which are located on both sides of the tamping machine 44, which can improve the control force on the tamping plate 45 and thus ensure the stability of the angle of the tamping plate 45. In addition, since the tamping machine 44 will bounce back and forth when it is working, a tensioner 64 is installed on the walking frame 3 between the two rotating shafts 61 to tighten the elastic adjustment rope 62. The tensioner 64 keeps the elastic adjustment rope 62 in a relatively taut state to reduce the large angle change of the tamping plate 45 when the tamping machine 44 is working, thereby improving the stability and efficiency of slope compaction.

[0025] To cope with the vibration of the rammer 44 during operation, such as Figure 2 , Figure 3 As shown, the walking frame 3 has a clearance opening 31 in the middle, which is larger than the support frame 41. Part of the support frame 41 passes through the clearance opening 31 and is positioned above the walking frame 3. Multiple inclined support springs 32 are installed in the clearance opening 31 and connected to the support frame 41. The support springs 32 can not only absorb the vibration force generated on the walking frame 3 when the rammer 44 is working, but also limit the rammer 44 to prevent the working direction of the rammer 44 from deflecting, thereby ensuring the stability of rammering.

[0026] To ensure the stability of the traveling frame 3 when the rammer 44 is working, such as Figure 2As shown, sleeves 33 for steel cables 52 to pass through are installed on the surfaces of the walking frame 3 on both sides of the clearance opening 31. The sleeves 33 are fixed to the surface of the walking frame 3. A guide ring 34 is installed on the surface of the walking frame 3 at the end of the sleeve 33 away from the cable roller 51 to prevent the steel cables 52 from shaking. Under the action of the guide ring 34 and the rotating shaft 61, the force point of the steel cables 52 can be made around the surface of the walking frame 3. Under the traction of the steel cables 52, the walking frame can be effectively prevented from running off-center or overturning, thereby improving the stability of the walking frame 3 when it moves.

[0027] To further improve the stability of the traveling frame 3 during movement, such as Figure 2 , Figure 3 As shown, there are four travel wheels 35. The four travel wheels 35 are installed at the four corners of the walking frame 3 through a liftable suspension device 36. The liftable suspension device 36 can ensure the ground-hugging effect when the walking frame 3 moves on slopes of different inclines, thereby providing strong stability for the trimming mechanism 4.

[0028] The method of using this invention is as follows:

[0029] In use, the repair device is transported to the embankment by the transport vehicle 1, and then the traveling frame 3 is lifted by the crane 2. The steel cables 52 on the two side cable rollers 51 are then pulled out, while the steel cable 52 on the middle cable roller 51 remains wound around. The steel cables 52 are then secured with fixing nails. Next, the steel cable 52 on the middle cable roller 51 is connected to the crane 2. At this point, the power cable 54 is connected to the transport vehicle 1. The transport vehicle 1 can carry a generator 57 or another generator vehicle can be used for power supply. The pneumatic motor 57 drives the support shaft 5 to rotate. As the support shaft 5 rotates, the steel cables 52 on both sides are wound back onto the cable rollers 51, and the steel cable 52 in the middle is gradually released from the cable rollers 51. At this point, the three steel cables 52 are used for… The support frame 3 moves on the slope and prevents slippage and displacement. The three sets of cable rollers 51 are designed with opposite directions to ensure good locking and maintain the compaction efficiency of the slope. The power cable 54 exits in the same direction as the steel cable 52 in the middle, which prevents the power cable 54 from getting tangled and ensures the working condition of the slope repair device. As the motor 57 rotates, the walking frame 3 moves at a constant speed along the slope. During the movement, the rammer 44 works, driving the rammer plate 45 to compact the slope. During the compaction of the slope, the angle between the rammer plate 45 and the slope can be controlled by rotating the servo motor 63 to handle slopes with different curvatures.

[0030] Using this slope repair device eliminates the need to create a road on the slope to accommodate the excavator, thereby reducing the land area occupied by the slope. At the same time, the slope repair device can be remotely controlled to compact the slope, effectively ensuring the safety of workers.

Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and the present invention omits descriptions of well-known components, processing technologies, and processes to avoid unnecessarily limiting the present invention.
