Description
Technical Field
[0001] The utility model belongs to the technical field of road construction, in particular to a construction road surface scraping device. Background Art
[0002] Road surface smoothness is a key parameter in road construction and directly impacts vehicle driving comfort. Driving on a smooth surface allows vehicles to travel more smoothly, reducing bumps and vibrations, thereby improving passenger comfort. Conversely, an uneven surface can cause jerking and unsettling rides, potentially causing discomfort to both the vehicle and passengers. Furthermore, uneven surfaces can increase vehicle wear and damage. Driving on bumpy surfaces subjects the vehicle's suspension system, tires, and other components to additional shock and vibration, leading to accelerated wear and increased repair costs. Furthermore, uneven surfaces can impair vehicle handling and stability, increasing the risk of traffic accidents. Therefore, maintaining good road surface smoothness is crucial for road management and transportation.
[0003] During construction of existing cement pavements, a drive unit is used to drive a scraper to smooth the pavement and maintain its smoothness. However, the drive unit is typically placed outside the construction area to avoid affecting the smoothness of the pavement. Since these areas are often uneven, the scraper may tilt and vibrate during movement, ultimately affecting the smoothness of the pavement.
[0004] Therefore, a construction road surface scraping device is needed. Utility Model Content
[0005] The purpose of this utility model is to provide a road surface scraping device for construction, thereby solving the problem that the scraper of existing cement pavement may tilt and vibrate during construction, which affects the smoothness of the road surface during construction. The specific technical solution is as follows:
[0006] A construction road surface scraping device includes a drive unit and guide rails, which are symmetrically installed on both sides of the road, and the drive unit travels on the guide rails; it also includes an electric push rod, a connecting block, a telescopic rod, an electronic level, a distance sensor, a sleeve, a hinge, a support rod and a scraper, the electric push rod is installed on the drive unit, the connecting block is fixedly installed on the movable end of the electric push rod, one end of the telescopic rod is rotatably connected to the telescopic rod through a hinge, the two ends of the sleeve are respectively slidably connected to the end of the telescopic rod away from the hinge, the support rod is vertically installed at the bottom of the sleeve, the scraper is installed on the support frame, the electronic level is installed at the center of the top of the sleeve, the electronic level is electrically connected to the electric push rod, and the distance sensor is installed on the sleeve.
[0007] Preferably, a sliding groove is provided on the top of the telescopic rod, ribs are installed at both ends of the sleeve, a slider is installed at one end of the rib close to the telescopic rod, and the slider is slidably installed in the sliding groove.
[0008] Preferably, a partition is installed in the middle of the sleeve, and a movable groove is opened at one end of the telescopic rod away from the hinge. A spring is installed in the movable groove, and both ends of the spring are elastically supported against the bottom of the movable groove and the partition respectively.
[0009] Preferably, a limiting block for preventing the telescopic rod from being separated from the sleeve is installed at one end of the sliding groove away from the hinge.
[0010] Preferably, mounting grooves are provided at both ends of the scraper, and a fixing plate is slidably installed on the mounting groove. Arc working surfaces are provided on both sides of the fixing plate, and the arc working surfaces are tangent to the working surface of the scraper. Locking plates for fixing the fixing plates are installed at both ends of the scraper close to the support rod through bolts.
[0011] Preferably, the cross-sectional shape of the telescopic rod is a non-rotating body, and the cross-sectional shape of the sleeve is a non-rotating body corresponding to the telescopic rod.
[0012] Compared with the existing technology, the utility model has the following beneficial effects:
[0013] 1. The utility model uses an electronic level to constantly detect the inclination angle of the scraper, thereby adjusting the extension length of the electric push rod. The rotation and relative movement of the telescopic rod and the sleeve ensure that the scraper is always in a horizontal state. Compared with the existing method that cannot be adjusted horizontally, the utility model further improves the flatness of the road surface.
[0014] 2. The utility model installs springs at both ends of the partition to connect with the telescopic rod. When the telescopic rod and the sleeve move relative to each other, the springs will be squeezed or stretched. The tension balance of the two springs ensures that the sleeve is always located in the middle position of the electric push rod, avoiding the scraper from deviating and being misaligned with the constructed road.
[0015] 3. The utility model can construct road surfaces with different inclination angles according to actual conditions by autonomously adjusting the extension distance of the electric push rod, thereby improving the practicality of the road surface leveling device during construction.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example, reference Figures 1 to 3 .
[0024] Guide rails 2 are laid on both sides of the construction road surface. However, due to the uneven ground conditions, the guide rails 2 on both sides may be uneven in height or even tilted. The drive unit 1 and guide rail 2 are used in conjunction with each other, and the drive unit 1 can move on the guide rail 2. The drive unit 1 can be a linear drive mechanism such as a motor and roller or a screw and slider 20.
[0025] The electric push rod 3 is mounted on the drive unit 1 via bolts, the connecting block 4 is fixedly mounted on the movable end of the electric push rod 3 via bolts, one end of the telescopic rod 5 is rotatably connected to the telescopic rod 5 via a hinge 8, and both ends of the sleeve 7 are slidably connected to the end of the telescopic rod 5 away from the hinge 8. The support rod 9 is vertically mounted on the bottom of the sleeve 7 via bolts, the scraper 10 is mounted on the support frame via bolts, the electronic level 6 is mounted at the center of the top of the sleeve 7 via bolts, the electronic level 6 is electrically connected to the electric push rod 3, and a distance sensor is mounted on the sleeve 7. The cross-sectional shape of the telescopic rod 5 is a non-rotating body, and the cross-sectional shape of the sleeve 7 is a non-rotating body corresponding to the telescopic rod 5. The non-rotating telescopic rod 5 and sleeve 7 can prevent relative rotation between the two, which would affect the perpendicularity of the scraper 10 to the road surface.
[0026] When the electronic level 6 detects that the scraper 10 is tilted, the electric push rod 3 is activated according to the angle and direction of the tilt, and the corresponding telescopic length of the electric push rod 3 is adjusted. The distance sensor detects the distance between the sleeve 7 and the construction road surface, and adjusts the scraper 10 to a horizontal state while ensuring that the distance remains unchanged. The angle adjustment of the scraper 10 can be performed simultaneously with the advancement of the drive unit 1. During the adjustment process, the linear distance between the connecting blocks 4 will change. Therefore, the present application adopts a structure of a telescopic rod 5 in conjunction with the sleeve 7 and hinge 8 to ensure the stability of the advancement of the drive unit 1 while adjusting the angle of the scraper 10.
[0027] In another embodiment, when the actual situation requires that the road surface be constructed at a certain fixed inclination angle, the electronic level 6 can be set to a fixed angle, and the electric push rod 3 can be started to keep the scraper 10 always at a certain inclination angle, so as to construct a road surface with an inclination angle, thereby improving the practicality of the construction road surface leveling device.
[0028] The telescopic rod 5 and the sleeve 7 can also be used to adjust the width of the road surface, and can be stretched and adjusted to suit different widths of the road surface, so that the present application can be used in road construction in most cases.
[0029] A slot 11 is defined at the top of the telescopic rod 5. Ribs 12 are bolted to each end of the sleeve 7. A slider 20 is bolted to the end of the rib 12 closest to the telescopic rod 5. The slider 20 slides within the slot 11. A stopper 16 is attached to the end of the slot 11 away from the hinge 8. When the telescopic rod 5 moves relative to the sleeve 7, the slider 20 moves within the slot 11, ensuring that the rib 12 remains connected to the telescopic rod 5 and sleeve 7. This provides further support for the telescopic rod 5 as it extends, preventing deformation of the sleeve 7 and support rod 9, which could affect the smoothness of the construction road surface. The stopper 16 prevents the telescopic rod 5 from accidentally detaching from the sleeve 7, causing the electric actuator 3 to tip over and potentially damaging components.
[0030] A partition 14 is installed in the middle of the sleeve 7. A movable slot 13 is defined at the end of the telescopic rod 5 away from the hinge 8. A spring 15 is installed in this movable slot 13. The ends of the spring 15 elastically contact the bottom of the movable slot 13 and the partition 14, respectively. When the telescopic rod 5 and sleeve 7 move relative to each other, the spring 15 is compressed or stretched. The balanced tension of the two springs 15 ensures that the sleeve 7 is always centered in the electric push rod 3, preventing the scraper 10 from shifting and becoming misaligned with the constructed road.
[0031] The scraper 10 has mounting grooves at both ends, and a fixing plate 17 is slidably mounted on the mounting grooves. Circular arc working surfaces 18 are provided on both sides of the fixing plate 17, and the circular arc working surfaces 18 are tangent to the working surface of the scraper 10. Locking plates 19 for fixing the fixing plates 17 are bolted to both ends of the scraper 10 near the support rod 9. The mounting grooves can be used to quickly install the fixing plates 17 or add scrapers 10 to improve work efficiency. Since the central angle of the circular arc working surface 18 of the fixing plate 17 is 90°, the other side of the circular arc working surface 18 that is not tangent to the working surface of the scraper 10 will be parallel to the forward direction of the scraper 10. This allows the scraper 10 to reduce the amount of excess cement that is pushed out of the road surface when leveling the cement road surface, thereby reducing waste.
[0032] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can make modifications, substitutions, variations and various different choices and changes to the embodiments without creative contribution as needed after reading this specification without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
