Description

Technical Field

[0001] The utility model belongs to the technical field of road construction machinery, and more specifically, relates to an integrated equipment for highway construction, leveling and rolling. Background Technique

[0002] In highway construction, during the construction of large-area filled subgrades, multiple devices usually need to cooperate with each other to complete the work. The traditional methods mainly rely on bulldozers, graders, and rollers, and the technology is relatively mature. However, there are also many problems in actual applications:

[0003] (1) In traditional subgrade filling construction, a bulldozer is required to first level the soil on the grid land, and then the grader is used to adjust it multiple times. However, it is very difficult to control the flatness of the leveled ground, and the effect is often still not ideal. Multiple and repeated operations are required, resulting in low construction efficiency and difficult guarantee of construction quality.

[0004] (2) During the compaction stage of the roller, in the face of factors such as tight construction periods and weather conditions that affect subgrade construction, for subgrades of different widths, the compaction working surface is relatively fixed, and the longitudinal and transverse slopes cannot be guaranteed, resulting in uneven compaction.

[0005] Patent number: CN202020284189.2, patent name: A utility model patent for a ground grader for highway construction. By installing a rotating drum, a conveyor belt, and a baffle, the problems of compacting the soil and preventing soil overflow are solved. However, it cannot operate on subgrades of different widths at one time and requires multiple machines to cooperate, and it cannot effectively connect the processes, reducing the construction efficiency.

[0006] Patent number: CN202111058243.7, patent name: An invention patent for a subgrade intelligent compaction forming device. By setting a rotating special-shaped plate and arranging multiple guiding rotating pipes at the bottom of the special-shaped plate, the accumulated sundries are pushed to avoid the roller pressing the sundries into the subgrade soil layer, ensuring the quality of the roller compacting the subgrade. However, the device is only suitable for subgrade compaction on flat roads, and the applicable working scenarios are single.

[0007] Patent number: CN202210776465.0, patent name: An invention patent for a grader for subgrade construction in earthwork projects. By arranging a movable sleeve and a toothed block between two scrapers, the toothed block and the moving block mesh with each other to form a wedge design. The meshing of the toothed block and the moving block causes the movable sleeve to move downward to push the pressing plate downward, realizing the pre-compaction of the surface of the cut soil. The device has a complex structure and low automation, and it is difficult to be applied to the flattening work of large-area earth-rock subgrades. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] By Figures 1 to 4As shown in the figure, the utility model provides a highway construction flat rolling integrated device, including a front-end sensor 1 arranged at the front end of the frame 1. A leveling device and a rolling device are respectively arranged at the front and rear ends of the frame 1. A central sensor 5 and a driving device 6 are also arranged on the frame 1. The central sensor 5 is respectively connected to the front-end sensor 1, the leveling device, the driving device 6 and the rolling device, and is used to receive and analyze the road surface information collected by the front-end sensor 1, and control the leveling device, the driving device 6 and the rolling device. The rolling device includes a first hydraulic telescopic system 11 and a hydraulic power roller 7. One end of the first hydraulic telescopic system 11 is connected to the central sensor 5, and the other end is connected to the hydraulic power roller 7. The first hydraulic telescopic system 11 can control the automatic expansion and contraction of the width of the hydraulic power roller 7 and roll the road surface to ensure the flatness and compaction degree of the roadbed.

[0029] The leveling device includes a second hydraulic telescopic system 12, a hydraulic rod 3, a connecting device and a leveling blade 4. The second hydraulic telescopic system 12 is connected to the driving device 6 and the central sensor 5. The second hydraulic telescopic system 12 is also connected to the hydraulic rod 3. There are two hydraulic rods 3 which are respectively arranged on both sides of the frame 1. The bottom of the hydraulic rod 3 is connected to the connecting device. The bottom of the connecting device is connected to the leveling blade 4. The connecting device includes a connecting seat 9 and two connecting frames 10. The connecting seat 9 is disc-shaped. The upper surface of the connecting seat 9 is fixedly connected to the bottom of the hydraulic rod 3. The left and right sides of the lower surface of the connecting seat 9 are respectively fixedly connected to the tops of the connecting frames 10. The bottoms of the connecting frames 10 are fixedly connected to the leveling blade 4. The second hydraulic telescopic system 12 drives the hydraulic rod 3 to expand and contract in the vertical direction, and can simultaneously drive the two hydraulic rods 13 to adjust the height of the leveling blade 4, or only drive one of the hydraulic rods 3 to expand and contract, so that the leveling blade 4 is tilted, which can be applied to the leveling of road surfaces with different slopes.

[0030] The driving device 6 is a driving motor. The driving device is connected to the first hydraulic telescopic system 11 and the second hydraulic telescopic system 12 to provide power.

[0031] The cross-sectional shape of the leveling blade 4 is arc-shaped or rectangular; the central sensor 5 is an intelligent sensor of type BHI260 or BHA260 of Bosch Sensortec.

[0032] It also includes a protective plate 8. The protective plate 8 is arranged above the tires at the front end of the frame 1, and is used to block sundries or mud brought by the tires from splashing onto the leveling blade 4, ensure the flatness of the road surface, and guarantee the leveling quality.

[0033] The front-end sensor 2 is equipped with an ultrasonic probe. By generating and receiving ultrasonic waves and calculating the time of emission and the time experienced for reception, the target distance can be measured, and the ground elevation, cross-section, and slope data of the front section of the road can be collected in real time. The front-end sensor 1 is a KT40-1602E type ultrasonic sensor or a TCT40-10T type piezoelectric ultrasonic sensor.

[0034] Both the first hydraulic telescopic system 11 and the second hydraulic telescopic system 12 consist of a hydraulic pump, a fuel tank, a hydraulic valve, and a hydraulic cylinder. When the hydraulic pump is started, hydraulic oil is sucked in and the pressure increases. Then, the hydraulic valve controls the flow direction and pressure of the oil. When telescopic operation is required, the hydraulic valve transfers the pressure to the hydraulic cylinder, causing its piston to produce linear motion, thereby realizing the telescoping of the cylinder body. The hydraulic cylinder is connected to the hydraulic power roller 7 and the hydraulic rod 3, and further controls their telescoping.

[0035] The working process of the integrated road construction and leveling and rolling equipment of the present utility model is as follows:

[0036] Step 1: According to the width of the subgrade compacted by the grader required for road construction, adjust the width of the hydraulic power roller 7 and the height of the hydraulic rod 3.

[0037] Step 2: When the equipment is working, the front-end sensor 1 collects the elevation, cross-section, and slope data of the ground after filling in real time and transmits them to the central sensor 5.

[0038] Step 3: The central sensor 5 analyzes the data sent by the front-end sensor 1, sends corresponding instructions to the driving device 6, and controls the adjustment of the width, height, and angle of the hydraulic power roller 7 and the hydraulic rod 3 to ensure that the leveling height is at the same elevation, realizing one-time leveling and rolling work.

[0039] The present utility model collects and processes data by setting a central sensor and a front-end sensor. The central sensor is connected to the driving device, the scraping device, and the rolling device. The central sensor analyzes the collected data and transmits control instructions to the scraping device and the rolling device. The integrated design realizes the two processes of subgrade leveling and compaction, solves the problem of repeated work required, and improves construction efficiency;

[0040] At the same time, by setting the first hydraulic telescopic system and the second hydraulic telescopic system to be connected to the rolling device and the scraping device respectively, the automatic telescoping of the hydraulic power roller and the inclination angle of the scraping blade can be controlled, which can meet the subgrade construction with different subgrade widths and slope ratios, solves the problem of excessive deviation in road surface flatness caused by too high or too low blade height after the operation of the traditional grader, and ensures the flatness and compaction degree of the subgrade.

[0041] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
