Description

Technical Field

[0001] This utility model relates to the field of roadbed construction technology, and in particular to a compaction device for high embankment roadbeds. Background Technology

[0002] The roadbed is the foundation of the road surface or track. The main function of the roadbed is to provide the necessary conditions for vehicle operation. When building a road, the first step is to excavate the roadbed. Since the roadbed is newly excavated, it is uneven. At this time, we need to use a roadbed compaction device to compact and level the roadbed before pouring concrete or asphalt on it.

[0003] A search revealed a Chinese patent disclosure for a compaction device for high embankment roadbed construction (authorization announcement number CN213538581U), comprising a body, a connecting rod, and a handle. The connecting rod is fixedly connected to the right side of the body, and the handle is connected to the top of the connecting rod. A bandage is fixedly connected to the tail end of the handle, and the other end of the bandage is connected to a winding device located below the handle. The winding device includes a cylinder, the middle part of the side walls on both sides of the cylinder is hollow, and a rotating shaft is placed in the hollow layer. Through holes with the same radius as the inner ring of the bearing are opened on the inner and outer sides of the side walls of the cylinder, corresponding to the inner ring of the bearing of the rotating shaft. A central rotating shaft passes through the middle of the through holes. Rectangular protrusions are provided on the upper, lower, left, and right sides of the right side of the central rotating shaft. A connector is also fixedly connected to the right side of the cylinder. An inner ring channel with the same diameter as the central rotating shaft is excavated on the inner side of the connector, and grooves with the same shape and size as the right side of the central rotating shaft are opened on the upper, lower, left, and right sides of the inner ring channel.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that there are many compaction machines on the market, such as road rollers and push compactors, which mainly compact by their own weight and vibration. However, when faced with soil and rock fill with large particle size variations and uneven moisture content, they cannot adjust the compaction effect of the compaction device according to the fill area with different particle size and moisture content, and are prone to damaging the structure of the fill, thereby affecting the overall performance of the roadbed. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a high embankment roadbed compaction device.

[0006] The technical solution of this utility model is as follows: a high embankment roadbed compaction device includes a compactor, with drive rollers rotatably connected to both sides of the compactor, and compaction rollers fixedly connected to the ends of the drive rollers away from the compactor. Compaction grooves are equidistantly opened on the outer sides of the compaction rollers, and a vibrating motor is fixedly installed inside each compaction groove. A compaction surface is slidably connected inside each compaction groove. The piston end of each vibrating motor is fixedly connected to the corresponding compaction surface. A sensor is fixedly installed at the bottom of the compactor, and a hydraulic shock absorber is provided inside each compaction surface.

[0007] By adopting the above technical solution and through this design, differentiated compaction of different areas can be achieved on the same roadbed, thereby improving the applicability of the device. An intelligent sensing system is introduced, which monitors the moisture content and compaction degree of the fill material in real time through sensors, and dynamically adjusts the working parameters of the hydraulic shock absorber and the vibration motor to achieve the best compaction effect. Through the setting of the hydraulic shock absorber, the pressure of the compaction roller on the fill material can be controlled in real time by adjusting the internal pressure. This can both protect the fill material from being over-crushed and ensure a good compaction effect.

[0008] In a preferred embodiment, a leveling mechanism is provided on the outside of the compactor. The leveling mechanism includes lifting rods rotatably mounted on both sides of the compactor. A push plate is fixedly mounted between one end of the two lifting rods. A hydraulic cylinder is rotatably mounted on the top of the push plate. Two supports are fixedly connected to the outside of the compactor. The piston rod of the hydraulic cylinder is rotatably connected to the two supports.

[0009] By adopting the above technical solution, the extension and retraction of the piston rod of the hydraulic cylinder can drive the push plate to rotate, thereby enabling the push plate to adapt to the leveling operation of roadbeds at different heights.

[0010] In a preferred embodiment, the compactor is provided with a power mechanism, which includes an installation cavity at the front end of the compactor. A dual-head motor is fixedly installed inside the installation cavity, and the output shafts of the dual-head motors are fixedly connected to corresponding transmission rollers.

[0011] By adopting the above technical solution, the rotation of the output shaft of the dual-head motor can drive the transmission roller and the compaction roller to rotate.

[0012] In a preferred embodiment, the top of the compactor is provided with an operating platform, a display screen is fixedly installed inside the operating platform, and an operating panel is fixedly installed inside the operating platform.

[0013] By adopting the above technical solution and setting up the display screen, staff can intuitively see the sensor monitoring data.

[0014] In a preferred embodiment, the compactor is provided with rotating wheels on both sides, and the outer side of each rotating wheel is provided with anti-slip texture.

[0015] By adopting the above technical solution, the coefficient of friction between the rotating wheel and the ground can be increased.

[0016] In a preferred embodiment, ladders are fixedly installed on both sides of the compactor and below the operating platform.

[0017] By adopting the above technical solution and installing a ladder, it is easy for staff to enter the operating console.

[0018] In a preferred embodiment, the hydraulic cylinder, sensor, dual-head motor, vibration motor, hydraulic shock absorber, and display screen are all electrically connected to the operation panel.

[0019] By adopting the above technical solution, the hydraulic cylinder, sensor, dual-head motor, vibration motor, hydraulic shock absorber and display screen can be started and stopped through the operation panel settings.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the compaction roller adopts a segmented design, that is, compaction grooves are equally spaced inside the compaction roller. The vibration motor in each compaction groove can independently control the vibration frequency and amplitude to adapt to the filling areas with different particle sizes and moisture contents. When facing the filling area with high particle size and high moisture content, the compaction roller can be rotated through the power mechanism, thereby enabling the corresponding vibration motor to face the roadbed that needs to be compacted. Through this design, differentiated compaction of different areas can be achieved on the same roadbed to improve the applicability of the device. An intelligent sensing system is introduced to monitor the moisture content and compaction degree of the filling in real time through sensors, and dynamically adjust the working parameters of the hydraulic shock absorber and the vibration motor to achieve the best compaction effect. Through the setting of the hydraulic shock absorber, the pressure of the compaction roller on the filling can be controlled in real time by adjusting the internal pressure. This can protect the filling from being over-crushed and ensure good compaction effect.

[0022] 2. In this utility model, the extension and retraction of the piston rod of the hydraulic cylinder can drive the push plate to rotate, and the lifting rod setting can make the push plate more stable during rotation, so that the push plate can adapt to the leveling operation of roadbeds of different heights and further improve the compaction effect of the roadbed.

A vibratory motor 14 is fixedly installed inside each compaction groove 13. A compaction surface 15 is slidably connected inside each compaction groove 13. The piston end of each vibratory motor 14 is fixedly connected to the corresponding compaction surface 15. A sensor 9 is fixedly installed at the bottom of the compactor 1. Hydraulic shock absorbers 16 are installed inside each compaction surface 15. The compaction roller 4 adopts a segmented design, i.e., compaction grooves 13 are equidistantly opened inside the compaction roller 4. The vibratory motor 14 in each compaction groove 13 can independently control the vibration frequency and amplitude to adapt to... For areas with different particle sizes and moisture contents, when facing areas with higher particle sizes and moisture contents, the power mechanism can drive the compaction roller 4 to rotate, thereby aligning the corresponding vibratory motor 14 with the subgrade that needs to be compacted. This design allows for differentiated compaction of different areas on the same subgrade, improving the applicability of the device. Furthermore, an intelligent sensing system is introduced, using sensor 9 to monitor the moisture content and compaction degree of the filler in real time, dynamically adjusting the operating parameters of the hydraulic shock absorber 16 and the vibratory motor 14 to achieve optimal compaction. The hydraulic shock absorber 16 allows for real-time control of the pressure exerted by the compaction roller 4 on the filler by adjusting its internal pressure, thus protecting the filler from excessive crushing while ensuring good compaction results.

[0030] Reference Figure 1 A leveling mechanism is provided on the outside of the compactor 1. The leveling mechanism includes lifting rods 5 rotatably mounted on both sides of the compactor 1. A push plate 8 is fixedly mounted between one end of the two lifting rods 5. A hydraulic cylinder 7 is rotatably mounted on the top of the push plate 8. Two supports 6 are fixedly connected to the outside of the compactor 1. The piston rod of the hydraulic cylinder 7 is rotatably connected to the two supports 6. By extending and retracting the piston rod of the hydraulic cylinder 7, the push plate 8 can be driven to rotate. The lifting rods 5 make the push plate 8 relatively stable during rotation, so that the push plate 8 can adapt to the leveling operation of roadbeds of different heights and further improve the compaction effect of the roadbed.

[0031] Reference Figure 3 The compactor 1 is equipped with a power mechanism, which includes an installation cavity 11 located at the front end of the compactor 1. A dual-head motor 10 is fixedly installed inside the installation cavity 11. The output shafts of the dual-head motor 10 are fixedly connected to the corresponding transmission rollers 12. By rotating the output shafts of the dual-head motor 10, the transmission rollers 12 and the compaction roller 4 can be driven to rotate, thereby realizing the transmission of power.

[0032] Reference Figure 2The top of the compactor 1 is equipped with an operating platform 17, and a display screen and an operating panel are fixedly installed inside the operating platform 17. Through the display screen, the staff can intuitively see the monitoring data of the sensor 9 and make timely adjustments to the compaction device.

[0033] Reference Figure 1 The compactor 1 has rotating wheels 3 on both sides. The outer side of the rotating wheels 3 is provided with anti-slip texture, which can increase the friction coefficient between the rotating wheels 3 and the ground, making the rotating wheels 3 more stable during the movement.

[0036] Working principle: First, the operator climbs into the operating platform 17 via ladder 2 and controls the hydraulic cylinder 7 to start via the control panel. The extension and retraction of the piston rod of the hydraulic cylinder 7 drives the push plate 8 to rotate, thus enabling the push plate 8 to adapt to the leveling operation of roadbeds at different heights, further improving the compaction effect of the roadbed. The compaction roller 4 adopts a segmented design, and the vibration motor 14 in each compaction groove 13 can independently control the vibration frequency and amplitude to adapt to the filling areas with different particle sizes and moisture contents. When facing the filling area with higher particle size and moisture content, the dual-head motor 10 can be started to drive the transmission roller. The compaction roller 12 and the compaction roller 4 rotate, thereby orienting the corresponding vibratory motor 14 toward the subgrade that needs to be compacted. Through this design, differentiated compaction of different areas on the same subgrade can be achieved to improve the applicability of the device. The moisture content and compaction degree of the fill material are monitored in real time by the sensor 9, and the working parameters of the hydraulic damper 16 and the vibratory motor 14 are dynamically adjusted to achieve the best compaction effect. By setting the hydraulic damper 16, the pressure of the compaction roller 4 on the fill material can be controlled in real time by adjusting the internal pressure. This can protect the fill material from being over-crushed and ensure a good compaction effect.
