Description

Technical Field

[0001] This invention relates to the field of cement-stabilized crushed stone base construction technology in road engineering, and in particular to a vehicle-mounted automatic edge compaction device for cement-stabilized base and its usage method. Background Technology

[0002] In road engineering, especially during the compaction of the edges of cement-stabilized crushed stone base courses, the conventional construction method is to use a road roller to directly compact the edges of the cement-stabilized base course. However, due to the large size of heavy compaction equipment, it is difficult to operate and there are blind spots. As a result, the operator cannot accurately align the compaction of the edges of the cement-stabilized base course, which can easily lead to insufficient compaction of the edges of the cement-stabilized base course, or the steel wheel being too wide and pushing open the edge template of the cement-stabilized base course, causing the edge of the cement-stabilized base course to collapse. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a vehicle-mounted automatic compaction device for the edge of water-stabilized soil and its usage method, aiming to solve the problems of inadequate compaction of the edge of water-stabilized soil and the bursting of the template at the edge of water-stabilized soil.

[0004] The present invention provides a vehicle-mounted automatic edge compaction device for water-stabilized soil, which adopts the following technical solution: A vehicle-mounted automatic edge compaction device for water-stabilized paver includes a paver body, a base plate, and a compaction assembly. A rear base plate is fixed to the rear of the paver body, and an installation assembly is provided below the base plate. The base plate is fixed to the rear base plate by the installation assembly. The compaction assembly includes a compaction plate, a variable frequency vibrating motor, and hydraulic rods. The variable frequency vibrating motor is fixed to the compaction plate. Two sets of hydraulic rods capable of adjusting the elevation angle of the compaction plate are provided between the compaction plate and the rear base plate. The top of the hydraulic rods is hinged to the base plate, and the bottom of the hydraulic rods is hinged to the compaction plate.

[0005] Optionally, the mounting components include a horizontal plate and two vertical plates. The horizontal plate is fixed to the top of the two vertical plates, and the tail support is located between the two vertical plates. One of the vertical plates is provided with a locking bolt, which passes through the vertical plate and is threadedly connected to the tail support. The vertical plate is fixed to the tail support by the locking bolt.

[0006] Optionally, a first drive assembly and a second drive assembly are provided between the platform plate and the cross plate. The first drive assembly is located below the second drive assembly. The first drive assembly can drive the second drive assembly and the platform plate to move together along the length direction of the rear platform. The second drive assembly can drive the platform plate to move along the direction of the vehicle body movement. The tamping assembly moves together with the platform plate. The first drive assembly includes a limiting plate, a slider, a threaded rod, and a handwheel. There are two limiting plates, which are fixed on the horizontal plate. The slider is located between the two limiting plates and can slide along the length of the limiting plates. There are two fixing blocks fixed on the horizontal plate, which are located on the front and rear sides of the horizontal plate respectively. Both ends of the threaded rod are rotatably connected to the fixing blocks. The threaded rod passes through the slider and is threadedly connected to the slider. One end of the threaded rod passes through the fixing block and is fixedly connected to the handwheel.

[0007] Optionally, a first camera is installed at the bottom of one of the vertical plates, and a second camera is installed below the support plate, with the second camera located directly above the variable frequency vibration motor.

[0008] This invention also discloses a method for using a vehicle-mounted automatic edge compaction device for water-stabilized soil, comprising the following steps: S1. Before the paver starts working, adjust the first drive assembly and the second drive assembly to make the compaction plate in a suitable position and adjust the elevation angle of the compaction plate. S2. The operator manually turns on the switch of the compaction device; S3. When the compaction device is in operation, the operator observes the images transmitted by the first and second cameras and adjusts the vibration frequency and elevation angle of the compaction plate according to the actual situation.

[0009] Compared with the prior art, the present invention has the following technical effects: The automatic compaction device of this invention achieves synchronization with the paver's operation, avoiding the resource waste of using small road rollers or manual plate compactors, effectively saving labor and equipment costs. Furthermore, it can adjust the compaction position laterally according to the road width, improving construction convenience. This invention uses hydraulic rods to automatically adjust the elevation angle and variable frequency vibration motors to dynamically adjust the vibration frequency according to the paver's own speed, achieving intelligent compaction of the base surface. The method of this invention enables remote control functionality, allowing the paver operator to control the vehicle-mounted automatic water-stabilized edge compaction device without leaving the driver's seat, avoiding the inconvenience of frequent machine stops during device debugging, and effectively improving construction efficiency and compaction quality.

Detailed Implementation

[0012] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.

[0013] Reference Figures 1-4 This invention discloses a vehicle-mounted automatic edge compaction device for water-stabilized paver, including a paver body 1, a support plate 2, and a compaction component 6.

The support plate 2 is fixed to the rear support plate 12 by the installation component 3.

[0014] Mounting assembly 3 includes a horizontal plate 31 and two vertical plates 32. The horizontal plate 31 is fixed to the top of the two vertical plates 32. The tail support 12 is located between the two vertical plates 32.

The first drive component 4 is located below the second drive component 5. The first drive component 4 can drive the second drive component 5 and the base plate 2 to move together along the length direction of the rear base plate 12. The second drive component 5 can drive the base plate 2 to move along the direction of movement of the vehicle body 1. The tamping component 6 moves together with the base plate 2.

[0016] The first drive assembly 4 includes a limiting plate 41, a slider 42, a threaded rod 44, and a handwheel 45. Two limiting plates 41 are provided, fixed to the horizontal plate 31. The slider 42 is located between the two limiting plates 41 and can slide along the length of the limiting plates 41. Two fixing blocks 43 are fixed on the horizontal plate 31, located on its front and rear sides respectively. Both ends of the threaded rod 44 are rotatably connected to the fixing blocks 43, passing through the slider 42 and threadedly connected to it. One end of the threaded rod 44 passes through the fixing block 43 and is fixedly connected to the handwheel 45. Rotating the handwheel 45 causes the threaded rod 44 to rotate, driving the slider 42 to move along the length of the limiting plate 41. The length of the horizontal plate 31 is aligned with the length of the tail support 12. The length of the horizontal plate 31 can be equal to the length of the tail support 12, and the length of the limiting plate 41 can be equal to the length of the horizontal plate 31. The structure of the second drive component 5 is the same as that of the first drive component 4.

[0017] The compaction assembly 6 includes a compaction plate 61, a variable frequency vibratory motor 62, and hydraulic rods 63. The variable frequency vibratory motor 62 is fixed to the compaction plate 61. Two sets of hydraulic rods are arranged between the compaction plate 61 and the tail support 12. Each set of hydraulic rods has two rods. The two hydraulic rods 63 closer to the tail support 12 constitute the first set of hydraulic rods, and the two hydraulic rods 63 further away from the tail support 12 constitute the second set of hydraulic rods. The top of the hydraulic rods 63 is hinged to the support plate 2, and the bottom of the hydraulic rods 63 is hinged to the compaction plate 61. The elevation angle of the compaction plate 61 can be adjusted by extending and retracting the hydraulic rods 63, such as extending both hydraulic rods 63 in the first set simultaneously and retracting both hydraulic rods 63 in the second set simultaneously.

[0018] A generator 11 is fixed on the vehicle body 1, which supplies power to the variable frequency vibratory motor 62.

The second camera 72 is installed below the support plate 2 and directly above the variable frequency vibratory motor 62. The second camera 72 can monitor the elevation angle of the compaction plate 61, allowing operators to see if the elevation angle is appropriate. The electronic display screen 73 is installed on the vehicle body 1. When the compaction device is working, the first camera 71 and the second camera 72 can transmit images to the electronic display screen 73 in real time. Operators can observe the electronic display screen 73 and adjust the vibration frequency of the compaction plate 61 according to the actual situation.

[0019] This invention also discloses a method for using a vehicle-mounted automatic edge compaction device for water-stabilized soil, comprising the following steps: S1. Before the paver starts working, adjust the first drive assembly 4 and the second drive assembly 5 to place the compaction plate 61 in a suitable position and adjust the elevation angle of the compaction plate 61.

[0020] S2. The operator manually turns on switch 8 of the compaction device; S3. When the compaction device is in operation, the operator observes the images transmitted by the first camera 71 and the second camera 72, and adjusts the vibration frequency and elevation angle of the compaction plate 61 according to the actual situation.

[0021] The automatic compaction device of this invention achieves synchronous operation with the paver, avoiding the resource waste of using small road rollers or manual plate compactors, effectively saving labor and equipment costs. Furthermore, it can adjust the compaction position laterally according to the road width, improving construction convenience. This invention uses a hydraulic rod 63 to automatically adjust the elevation angle and a variable frequency vibrator, dynamically adjusting the vibration frequency according to the paver's own speed changes, achieving intelligent compaction of the base surface. The method of this invention enables remote control, allowing the paver operator to control the vehicle-mounted automatic water-stabilized edge compaction device without leaving the driver's seat, avoiding the inconvenience of frequent machine stops during device debugging, and effectively improving construction efficiency and compaction quality.
