Description

Technical Field

[0001] This invention belongs to the technical field of road maintenance equipment, and relates to a crack treatment device for highway engineering. Background Technology

[0002] During road use, cracks may develop due to factors such as service life, environmental conditions, and construction quality. If cracks in asphalt pavement are not addressed promptly, rainwater can seep into the roadbed, reducing the structural strength of the pavement and potentially leading to road collapse and other safety hazards.

[0003] For smaller cracks, manual grouting is often used. This involves heating the raw material to 180-200 degrees Celsius, pouring it into a long-spouted pitcher, and then grouting the crack through the pitcher. High-temperature materials pose certain risks, and manual grouting is physically demanding. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a crack treatment device for highway engineering, which effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A crack treatment device for highway engineering, comprising:

[0007] An installation platform, the back of which is equipped with a push handle;

[0008] The movable wheels include a swivel wheel section located at the front end of the mounting platform and a fixed wheel section located at the rear end;

[0009] A heating vessel is fixedly installed on the mounting platform. A discharge pipe is provided at the bottom of the heating vessel, and the bottom of the discharge pipe passes through the mounting platform. The discharge pipe is located at the center of the line connecting the two fixed wheels.

[0010] A control valve is installed at the upper end of the discharge pipe. The control valve is connected to a return spring and a control component. The control end of the control component is installed at the push handle position.

[0011] A fire cage cover is fixedly installed on the outside of the heating vessel, and a gap is provided between the fire cage cover and the heating vessel;

[0012] A diesel burner is fixedly installed on the mounting platform, and the burner nozzle penetrates and is located inside the fire cage.

[0013] A temperature sensor is fixedly installed on the outer wall of the heating vessel at the end away from the diesel burner.

[0014] The control module is connected to a power supply, and the diesel burner and temperature sensor are both electrically connected to the control module.

[0015] Optionally, a cleaning fan is fixedly installed on the installation platform, and the output end of the cleaning fan passes through the installation platform and is located at the front end of the discharge pipe, with the output end of the cleaning fan tilted forward.

[0016] Optionally, a smoke hood is installed at the bottom of the installation platform, and the smoke hood surrounds the output end of the cleaning fan.

[0017] Optionally, a return air duct is fixedly connected to the upper end of the smoke hood, the return air duct is connected to a filter box, and the output end of the filter box is connected to the input end of the cleaning fan.

[0018] Optionally, a diesel generator is fixedly mounted on the mounting platform.

[0019] Optionally, a stirring assembly is fixedly installed at the upper end of the heating vessel. The stirring assembly includes stirring blades rotatably installed inside the heating vessel and a drive motor fixedly installed at the upper end of the heating vessel.

[0020] Optionally, the fixed wheel is equipped with an assist motor, and the control end of the assist motor is located on the push handle.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 4 This is an embodiment of the crack treatment device for highway engineering disclosed in this invention. Please refer to [link / reference]. Figure 1 and Figure 2 The system includes an installation platform 1, a push handle 11 at the rear end of the installation platform 1, and casters 2 at the bottom of the installation platform 1. The casters 2 include a swivel caster 21 at the front end and a fixed caster 22 at the rear end. A heating vessel 3 is fixedly mounted on the installation platform 1. A discharge pipe 31 is located at the bottom of the heating vessel 3, penetrating the installation platform 1. The discharge pipe 31 is located at the center of the line connecting the two fixed casters 22. Please refer to [link / reference needed]. Figure 3A control valve 32 is installed at the upper end of the discharge pipe 31. The control valve 32 is connected to a return spring 321 and a control component 322. The control end of the control component 322 is installed at the push handle 11. A cage hood 41 is fixedly installed on the outside of the heating vessel 3. A gap is provided between the cage hood 41 and the heating vessel 3. A diesel burner 42 is fixedly installed on the mounting platform 1. The nozzle of the diesel burner 42 passes through and is located inside the cage hood 41. A temperature sensor is fixedly installed on the outer wall of the heating vessel 3 at the end away from the diesel burner 42. A control module is also provided. The control module is connected to a power supply. The diesel burner 42 and the temperature sensor are both electrically connected to the control module.

[0035] Specifically, by pushing the push handle 11 to control the movement of the installation platform 1, the discharge pipe 31 is aligned with the crack to be filled. Asphalt sealant is placed in the heating vessel 3, and the diesel burner 42 is started to heat the vessel 3. A temperature sensor detects the temperature, causing the control module to intermittently start the diesel burner 42 to maintain the heating vessel 3 at a suitable temperature. During the filling process, the control valve 32 on the discharge pipe 31 is opened via the control component 322, allowing the asphalt sealant to flow into the crack.

[0036] In this way, by setting up the installation platform 1 to carry the diesel burner 42 and the heating vessel 3, it is convenient to carry out heating. At the same time, the staff can control the position of the discharge pipe 31 by controlling the push handle 11, which reduces the danger of the staff coming into contact with the high temperature of the vessel and reduces the labor intensity.

[0037] In some feasible configurations, the installation platform 1 is rectangular, and the push handle 11 can be shaped like a common electric bicycle handlebar for ease of operation. The bottom of the installation platform 1 is equipped with four movable wheels 2, with the rearmost being a fixed wheel section 22. The discharge pipe 31 is positioned at the center of the line connecting two of the fixed wheels 22, allowing the operator to easily align the discharge pipe 31 and guide it along the crack by pushing the handle 11 to control the two fixed wheels 22. Simultaneously, the front of the installation platform 1 is configured as a swivel wheel section 21 to accommodate any changes in the direction of the rear fixed wheels 22. To facilitate the spreading of the asphalt sealant, a V-shaped plate is rotatably mounted at the discharge pipe 31, with the bottom surface of the V-shaped plate in contact with the ground and the pointed corner of the V-shaped plate located at the crack. Torsion springs are installed at the rotation axes on both sides of the V-shaped plate to maintain pressure on the ground.

[0038] The heating vessel 3 and the flame cage 41 are cylindrical and non-axial. The flame cage 41 has a larger gap on the side where the diesel burner 42 is installed to facilitate heating. The upper ends of the heating vessel 3 and the flame cage 41 are closed. The upper end of the heating vessel 3 is provided with a feed inlet, which is hinged with a cover. An exhaust pipe is fixedly installed on the upper end of the heating vessel 3 and the flame cage 41. To reduce the influence of the open flame on the temperature sensor, a partition plate is placed inside the heating vessel 3 and the flame cage 41 to isolate the side where the temperature sensor is located, and it is filled with heat insulation material.

[0039] The discharge pipe 31 is a cylindrical tube with a tapered bottom. The control valve 32 can be a common ball valve controlled by a handle rotation. The control component 322 includes a brake cable and a brake lever. The brake lever is shaped like a bicycle handbrake and is installed at the push handle 11. Both ends of the brake cable are connected to the control valve 32 and the brake lever. The brake lever pulls the control valve 32 to open through the brake cable. To facilitate control and ensure that the control valve 32 is fully opened, an acceleration gear set can be set at the rotation shaft position of the control valve 32. The output end of the acceleration gear set is connected to the rotation shaft of the control valve 32, and the input end is connected to a long handle. The long handle is connected to the brake cable and the return spring 321.

[0040] The diesel burner 42 and temperature sensor are existing technologies and will not be described in detail here. The control module can be a microcontroller-based control module, which controls the start / stop or flame intensity of the diesel burner 42 by receiving temperature feedback from the temperature sensor. The power supply is a storage battery, which provides power to the control module, temperature sensor, and start-up module of the diesel burner 42.

[0041] As one specific embodiment of the crack treatment device for highway engineering provided in the application, please refer to Figure 1 and Figure 4 The cleaning blower 51 is fixedly installed on the installation platform 1. The output end of the cleaning blower 51 passes through the installation platform 1 and is located at the front end of the discharge pipe 31. The output end of the cleaning blower 51 is tilted forward.

[0042] Overall, when filling cracks, cleaning up dust can improve the bonding effect between the asphalt sealant and the road surface. By setting up a cleaning fan 51 to blow air through the cracks, the amount of gravel and other debris in the cracks can be reduced.

[0043] Further, please refer to Figure 4 A smoke hood 52 is installed at the bottom of the installation platform 1, and the smoke hood 52 surrounds the output end of the cleaning fan 51.

[0044] It should be understood that dust is reduced by setting up the smoke collection hood 52.

[0045] Further, please refer to Figure 2 and Figure 4The upper end of the smoke hood 52 is fixedly connected to the return air duct 521, the return air duct 521 is connected to the filter box 53, and the output end of the filter box 53 is connected to the input end of the cleaning fan 51.

[0046] It should be understood that by setting up the return air duct 521 and the filter box 53, the dust is further treated to reduce the impact on the environment. The output end of the filter box 53 is connected to the input end of the cleaning fan 51, and a certain negative pressure suction is formed at the position of the smoke hood 52, which facilitates the dust to enter the filter box 53.

[0047] In some feasible configurations, a rectangular sealed box is installed on the mounting platform 1, and a cleaning fan 51 is installed inside the sealed box. The output end of the filter box 53 is connected to the sealed box. When the cleaning fan 51 operates, it draws in air, creating negative pressure in the filter box 53, which in turn creates partial negative pressure in the fume hood 52, drawing in more air. The output end of the cleaning fan 51 then blows the dust, which enters the fume hood 52 and is drawn into the filter box 53. A filter screen is installed inside the filter box 53. The fume hood 52 is semi-cylindrical.

[0048] In some feasible methods, an activated carbon filter box can also be installed at the upper end of the heating vessel 3, which is connected to the heating vessel 3 through a pipe to filter the gas during the asphalt heating process.

[0049] Further, please refer to Figure 1 and Figure 3 The discharge pipe 31 is located at the lower end of the control valve 32 and is connected to the pressure-balancing pipe 54, with the open end of the pressure-balancing pipe 54 facing upward.

[0050] It should be understood that by setting up the pressure equalization pipe 54, after the control valve 32 is closed, the asphalt sealant in the discharge pipe 31 located at the lower end of the control valve 32 is allowed to flow out through the pressure equalization pipe 54, thereby reducing the possibility of it drying and causing blockage in the discharge pipe 31.

[0051] Furthermore, the pressure-regulating pipe 54 is connected to the output end of the cleaning blower 51, and both the pressure-regulating pipe 54 and the output end of the cleaning blower 51 are connected to an electrically controlled valve.

[0052] It should be understood that by setting a constant pressure pipe 54 to connect to the output end of the cleaning blower 51 and setting an electric control valve, when the grouting stops, the output end of the cleaning blower 51 is closed, allowing the airflow of the cleaning blower 51 to enter the constant pressure pipe 54, which facilitates the blowing out of the asphalt sealant and further reduces its residue in the discharge pipe 31.

[0053] In some feasible methods, the opening end of the pressure-regulating pipe 54 faces upward to reduce the possibility of asphalt sealant flowing out of the pressure-regulating pipe 54 during the grouting process. The pressure-regulating pipe 54 is located at the lower end of the control valve 32 and is usually not connected to the heating vessel 3, so the asphalt sealant will not enter the pressure-regulating pipe 54.

[0054] As another specific embodiment of the crack treatment device for highway engineering provided in the application, please refer to Figure 2 The diesel generator 6 is fixedly installed on the installation platform 1.

[0055] It should be understood that by setting up diesel generator 6, it is convenient to support electrical equipment and reduce the load on the power supply.

[0056] Furthermore, a stirring assembly 33 is fixedly installed on the upper end of the heating vessel 3. The stirring assembly 33 includes stirring blades rotatably installed inside the heating vessel 3 and a drive motor fixedly installed on the upper end of the heating vessel 3.

[0057] It should be understood that by setting up the stirring component 33, the asphalt is stirred during the heating process, which makes the heating more uniform, increases the melting speed, and reduces the possibility of burning at the heating point.

[0058] In some feasible methods, the sides and bottom of the stirring blades are in contact with the inner wall and bottom of the heating vessel 3 and rotate to scrape the asphalt, reducing adhesion to the heating vessel 3 and reducing the difficulty of cleaning after use.

[0059] Furthermore, the fixed wheel section 22 is equipped with a power assist motor 221, the control end of which is located on the push handle 11.

[0060] It should be understood that by setting up the assist motor 221, the labor intensity is reduced.

[0061] In some feasible ways, the control end of the power assist motor 221 can be selected as the rotary throttle of the electric bicycle to control the speed of the power assist motor 221, and the two power assist motors 221 can be controlled on both sides of the push handle 11 to control the steering.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
