Abstract
Description
Technical Field
[0001] This utility model relates to the field of road maintenance technology, and in particular to a highway pavement construction and maintenance device. Background Technology
[0002] After a highway is built, it will develop cracks or potholes due to wear and impact from vehicle wheels, as well as erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and melting ice during long-term use. These cracks and potholes on the highway surface greatly affect the safe passage of vehicles, so regular road maintenance is necessary. Currently, the method for dealing with cracks and potholes on the road is to fill the potholes with concrete.
[0003] The current publication, CN 217266857 U, published on August 23, 2022, discloses a road and bridge construction pavement maintenance device. This device slows down the curing speed of concrete in a storage tank, facilitating concrete use. It also automatically cleans dust and impurities from the road, reducing worker workload, lowering labor intensity, and improving work efficiency. It is highly practical. The device includes a mobile vehicle, a blower, air pipes, nozzles, a vacuum cleaner, a suction pipe, a storage tank, a concrete pump, a discharge pipe, a sealing plate, a first motor, a rotating shaft, spiral blades, and a lifting device. The blower is fixedly installed on the upper end of the mobile vehicle, and its output end is connected to the input end of the air pipe. A nozzle is installed at the output end of the air pipe. The vacuum cleaner is also fixedly installed on the upper end of the mobile vehicle.
[0004] The input end is equipped with a vacuum pipe, and the storage box is fixedly installed on the top of the mobile vehicle;
[0005] However, after using the device to fill the concrete, it is still necessary to manually smooth the concrete. Manually smoothing the concrete is time-consuming and labor-intensive, resulting in low road filling efficiency and high labor intensity for workers.
[0006] Another utility model patent with announcement number CN 219195599 U and announcement date of June 16, 2023 includes a base, a feeding mechanism fixedly installed on the left side of the top surface of the base, a discharge hard pipe provided on the surface of the feeding mechanism, an installation block fixedly sleeved on the surface of the discharge hard pipe, a concave surface opened on the left side of the installation block, a telescopic scraper assembly provided on the inner wall surface of the concave surface, a rotating mechanism provided on the left side of the installation block, a locking plate fixedly connected to the surface of the rotating mechanism, and the locking plate engaging with the telescopic scraper assembly;
[0007] This utility model uses a rotary mechanism to drive the locking plate to rotate, controlling whether the locking plate is engaged with the telescopic scraper assembly, thereby controlling the telescopic scraper assembly to extend and retract from the bottom of the mounting block. When concrete flows out from the bottom of the discharge pipe and the telescopic scraper assembly extends a suitable distance from the bottom of the mounting block, the telescopic scraper assembly will smooth the outflowing concrete. Concrete pouring and smoothing are carried out simultaneously, eliminating the need for subsequent manual smoothing.
[0008] This patent solves the technical problems existing in the publication number CN 217266857 U, but the following problems also exist in actual use: When using this device to repair pits, although the overflowing concrete is smoothed by the scraper, according to the process requirements, after the concrete is filled into the pit, due to the large number of air bubbles in the concrete, if the concrete is not vibrated, the density of the concrete itself will be reduced under the influence of the air bubbles, which will lead to poor adhesion with the roadbed around the pit and thus affect the service life.
[0009] Therefore, there is an urgent need for a highway pavement construction and maintenance device to smooth and vibrate concrete when filling potholes, thereby improving the density of the concrete and its adhesion to the surrounding roadbed, and extending its service life. Utility Model Content
[0010] To address the aforementioned technical problems, this utility model provides a highway pavement construction and maintenance device to solve the problem that existing maintenance devices lack the function of vibrating concrete when filling potholes, resulting in low concrete density, insufficient adhesion to the surrounding roadbed, and shortened service life.
[0011] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0012] A highway pavement construction and maintenance device includes a base plate with casters at the bottom and a material bucket on the base plate. A gantry is provided at one end of the base plate, and the gantry includes a crossbeam and a column. A slide rail is provided on one side of the column, and a vibratory smoothing unit is slidably mounted on the slide rail. The vibratory smoothing unit includes a support beam with guide holes at both ends. A guide rod is provided in the guide holes, and a vibratory seat is connected to one end of the guide rod. A vibratory motor is installed on the vibratory seat, and a smoothing plate is detachably mounted on one side of the vibratory seat.
[0013] The guide rod is fitted with an elastic element between the connecting beam and the vibration seat.
[0014] Furthermore, a threaded hole is provided in the middle of the crossbeam, and a lead screw is fitted in the threaded hole. One end of the lead screw is provided with a rotating disk, and the other end of the lead screw is rotatably connected to the support beam.
[0015] Furthermore, the smoothing plate includes a smoothing part and guide parts disposed on both sides of the smoothing part, wherein the guide parts form an angle of 135 degrees with the smoothing part.
[0016] Furthermore, the crossbeam has a V-shaped groove in the middle, and the rotating disk is located in the groove.
[0017] Furthermore, the material hopper is provided with a top cover, on which a stirring motor is installed. The output end of the stirring motor is provided with a stirring paddle. The bottom of the material hopper is provided with a discharge pipe that penetrates the bottom plate. A ball valve is provided inside the discharge pipe. The ball valve is provided with a rotating rod for controlling rotation. The rotating rod is provided with a handle.
[0018] Furthermore, at least one blower is provided at the end of the base plate away from the gantry.
[0019] Furthermore, the air outlet of the hair dryer is provided with an air outlet pipe, and the angle between the air outlet pipe and the base plate is 45 degrees.
[0020] Furthermore, one end of the guide rod is threaded with an anti-detachment cap.
[0021] Furthermore, one end of the gantry is symmetrically provided with handles.
[0022] In summary, the beneficial technical effects of this utility model are as follows:
[0023] (1) Use the handle to control the ball valve to open and fill the pit with concrete from the bucket. Then use the trowel to scrape off or smooth the overflowing or excess concrete. Next, use the vibrating motor to drive the vibrating seat and the trowel to vibrate and smooth the concrete. Vibration removes air bubbles from the concrete, making it denser. It also increases the adhesion between the concrete and the surrounding roadbed, making them a whole and extending the service life.
[0024] (2) Using a blower can blow out the loose soil and other debris in the pit before filling the concrete, so that the concrete can contact the pit better and the adhesion is stronger. Attached Figure Description

[0030] The present invention will now be described clearly and completely with reference to the embodiments.
[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0032] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] See appendix Figure 1-4 The image shows a highway pavement construction and maintenance device, including a base plate 1, wherein a caster wheel 2 is installed at each of the four corners of the bottom of the base plate 1, and a gantry is welded and fixed to one end of the base plate 1. The gantry includes two parallel columns 5 and a crossbeam 4 set between the two columns 5. A slide rail 6 is vertically installed on the opposite side of the two columns 5, and a vibratory smoothing unit is slidably provided between the two slide rails 6. At the same time, a reinforcing brace 27 is welded and fixed between the two columns 5 and the base plate 1.
[0034] The vibratory screeding unit includes a support beam 8, with sliders 9 at both ends of the support beam 8. The sliders 9 slide with the slide rail 6. Guide holes are vertically connected at both ends of the support beam 8, and guide rods 10 are installed in the guide holes. One end of the two guide rods 10 is connected to a vibratory seat 11. A vibratory motor 12 is installed on the vibratory seat 11 by bolts. A screeding plate 13 is installed on one side of the vibratory seat 11 by bolts. The screeding plate 13 includes a screeding part 16 for screeding concrete and inlet parts 17 on both sides of the screeding part 16. The two inlet parts 17 are symmetrical to each other and the included angle between them and the screeding part 16 is 135 degrees.
[0035] Furthermore, an elastic element 14 is fitted between the guide rod 10 and the vibrating seat 11 and the support beam 8. The elastic element 14 is specifically a compression spring. The force from the vibrating motor 12 can be transmitted to the vibrating seat 11 through the elastic element 14. During use, the concrete in the pit is smoothed by the trowel 13. At the same time, the vibrating motor 12 acts on the vibrating seat 11 and the trowel 13 to vibrate the concrete. The vibration removes air bubbles from the concrete, increases the density of the concrete, and makes the concrete bond more firmly with the roadbed around the pit, thus further extending the service life.
[0036] Furthermore, the middle of the crossbeam 4 is provided with a V-shaped groove 7, and a threaded hole is opened in the center of the bottom of the groove 7. A screw 18 is fitted in the threaded hole. One end of the screw 18 is provided with a rotating disk 19, and the other end of the screw 18 is rotatably connected to the support beam 8. During use, the rotation of the screw 18 can drive the entire vibratory troweling unit to slide up and down along the slide rail 6, thereby changing the force exerted by the vibratory motor 12 on the concrete. When it is necessary to increase the vibration force, the vibratory troweling unit can be lowered through the screw 18, which increases the adhesion between the troweling plate 13 and the concrete, making the vibration more thorough.
[0037] Furthermore, one end of the guide rod 10 is threaded with an anti-disengagement cap 15. The anti-disengagement cap 15 can prevent the guide rod 10 from disengaging from the guide hole, and at the same time, it can transmit force when the lead screw 18 pulls the vibration smoothing unit upward.
[0038] As a highway pavement construction and maintenance device, a material bucket 3 is provided on the base plate 1, a top cover 20 is provided on the material bucket 3, a mixing motor 21 is installed on the top cover 20, a mixing paddle is provided at the output end of the mixing motor 21, and a discharge pipe 22 is provided through the bottom of the material bucket 3 through the base plate 1. A ball valve is provided in the discharge pipe 22, and a rotating rod 23 is provided on the ball valve for controlling the rotation. A handle 24 is provided on the rotating rod 23. When filling the pit with concrete, the ball valve is opened by the handle 24 and the rotating rod 23 to allow the concrete to flow into the pit.
[0039] Furthermore, three blowers 25 are provided at the end of the base plate 1 away from the gantry. The air outlet end of the blower 25 is provided with an air outlet pipe 28. The angle between the air outlet pipe 28 and the base plate 1 is 45 degrees. When filling the pit, the blower 25 first blows out the loose soil and other particulate impurities in the pit in one direction, which is more conducive to the bonding between the concrete and the roadbed.
[0040] Finally, a handle 26 is symmetrically provided at one end of the gantry, and the entire device is moved by driving the handle 26.
[0041] In use, first push the entire device from one end of the pit to the other by using handle 26. At the same time, turn on the three blowers 25. The three blowers 25 use the inclined air outlet pipes 28 to blow the impurities in the pit out in the same direction. Then, place the discharge pipe 22 above the pit and open the ball valve by turning handle 24 to let the concrete in the material bucket 3 flow into the pit. After the concrete fills the pit, turn on the vibration motor 12 and then use the trowel 13 to vibrate and smooth the concrete.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
