Description

Technical Field

[0001] This utility model relates to the field of road surface construction technology, specifically a road surface crack cleaning and filling device. Background Technology

[0002] During concrete pavement construction, contraction joints and expansion joints are installed at regular intervals to prevent cracking caused by subsequent concrete shrinkage and expansion. After the concrete pavement construction is completed, the pavement needs to be cut into joints before grouting. However, after the concrete pavement joints are cut, mud, sand, and stones may become embedded in the gaps, so cleaning is necessary before grouting. Currently, the common method for cleaning is for workers to use handheld angle grinders or wire brushes. This method is labor-intensive and time-consuming, and after cleaning, special tools are needed again for grouting, making it inefficient. In addition, since the common cleaning method does not have measures to collect mud, sand, and stones, foreign objects may re-enter the gaps, making subsequent grouting difficult. Moreover, the common cleaning method raises a large amount of sand and dust during cleaning, which is detrimental to the health of construction workers and also pollutes the environment.

[0003] Therefore, how to provide a concrete pavement cleaning device that is easy to construct, efficient, labor-saving, reduces environmental pollution, and ensures the health of construction workers is a technical problem that urgently needs to be solved by those skilled in the art.

[0031] Various exemplary embodiments of the present invention are now described in detail. This detailed description should not be considered as a limitation of the present invention, but rather as a more detailed description of certain aspects, features, and implementations of the present invention.

[0032] Various improvements and variations can be made to the specific embodiments described in this utility model without departing from the scope or spirit of this utility model, which will be obvious to those skilled in the art. Other embodiments derived from this utility model description will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.

[0033] This utility model provides a road surface crack cleaning and filling device, such as Figure 1 The diagram shows the structural schematic of the road surface cleaning and filling device. In a specific embodiment, the device includes: a frame 1, with a driver's seat 2 located at the rear of the frame 1 along the direction of travel. A cleaning mechanism 3 for cutting and cleaning gaps is located at the front bottom of the frame 1, and a filling mechanism 4 for pouring asphalt is located on the frame 1 behind the cleaning mechanism 3, corresponding to the gaps. The cleaning mechanism 3 and the filling mechanism 4 are arranged one behind the other, achieving the purpose of cleaning before filling, greatly improving the construction efficiency of cleaning and filling.

[0034] The frame 1 is also equipped with a power module 5 for driving the frame 1 forward. The power module 5 is also electrically connected to the cleaning mechanism 3 and the filling mechanism 4, providing electrical power for operation. Preferably, the power module 5 can be a battery module or a generator module.

[0035] In addition, a lighting module 8 is provided on the front side of the frame 1 to provide construction lighting in low-light conditions, thereby improving construction speed and efficiency. Preferably, the lighting module is an LED headlight, and the power supply module 5 is electrically connected to the lighting module 8 to provide lighting power.

[0036] In this embodiment, the driver's seat 2 is equipped with control pedals for forward, reverse and stop, as well as a control board 9 for controlling each module on the joint cleaning and filling device. The control board 9 is connected to the control modules, which facilitates the control of various operations during construction.

[0037] Furthermore, the seam cleaning and filling device also has a dust suppression mechanism 6, which is set on the frame 1 at a position corresponding to the seam cleaning mechanism 3, and is used to suppress and remove dust during seam cleaning.

[0038] Furthermore, the dust suppression mechanism 6 includes a mist spraying assembly 61 and a dust suction assembly 62. The mist spraying assembly 61 is positioned in front of the grout cleaning mechanism 3 and is used to spray mist onto uncleaned grout areas to suppress dust, preventing the generation of large amounts of dust during grout cleaning, which could pollute the environment and reduce visibility during construction. In a specific embodiment, the mist spraying assembly 61 includes a water tank 611 and an electric nozzle 612. The water tank 611 is connected to the electric nozzle 612 via a pipe for water supply. The electric nozzle 612 is electrically connected to the control module of the driver's seat 2, which controls the mist spraying. The power supply module 5 is electrically connected to the electric nozzle 612 for power supply.

[0039] A dust collection component 62 is positioned above the seam cleaning mechanism 3 to collect and absorb the dust generated during seam cleaning. In this specific embodiment, the dust collection component 62 includes a vacuum cleaner 621 and a dust storage box 622. Before starting the seam cleaning mechanism 3, the vacuum cleaner 621 needs to be turned on to collect dust. When the seam cleaning mechanism 3 is running, it generates a large amount of dust. The vacuum cleaner 621 sucks this dust into the dust storage box 622, preventing dust from polluting the environment and avoiding obstruction of vision, thus minimizing the inhalation of dust by construction workers.

[0040] In a specific embodiment of this utility model, the seam cleaning and filling device also has a limiting wheel 7. The limiting wheel 7 is set at the bottom of the frame 1 at the position corresponding to the seam. The limiting wheel 7 can be inserted into the seam for movement limitation, ensuring that the seam cleaning mechanism 3 and the seam filling mechanism 4 can correspond to the position of the seam in real time and avoid deviation.

[0041] Furthermore, such as Figure 2 As shown, the limiting wheel 7 includes a connecting shaft 71 and two frustum wheels 72 fixed at both ends of the connecting shaft. The larger diameter ends of the two frustum wheels 72 are arranged opposite each other, and the frustum sides of the two frustum wheels 72 can be inserted into the gap. By inserting the frustum sides with a certain angle into the gap, it can adapt to gaps of different widths, thereby improving the applicability of the gap cleaning and filling device.

[0042] Furthermore, the frustum wheel 72 is engaged with the connecting shaft 71, which allows for adjustment of the position of the frustum wheel 72 axially on the connecting shaft 71 within a certain range, thereby enabling gaps of different widths and further expanding the applicability of the gap cleaning and filling device.

[0043] In addition, in this embodiment, multiple limiting wheels 7 of two different sizes are provided along the driving direction to adapt to gaps of different widths. The setting of multiple limiting wheels can more stably limit the movement and restrict the lateral displacement of the cleaning mechanism 3 and the filling mechanism 4, so that they can accurately clean and fill the gaps.

[0044] In a specific embodiment of this utility model, the seam clearing mechanism 3 includes an adjusting seat 31 and a cutter module 32. The adjusting seat 31 is fixedly installed at the bottom of the frame 1, and the cutter module 32 is movably engaged with the adjusting seat 31, allowing the height of the cutter module 32 to be adjusted up and down to accommodate seams of different depths.

[0045] The power supply module 5 is electrically connected to the tool module 32 to provide power to the tool module 32. In addition, the tool module 32 is electrically connected to the control module, which can control the operation of the tool module 32 through the control panel in the driver's seat.

[0046] Furthermore, the tool module 32 includes a drive motor and a cutting blade. The drive motor is movably latched onto the adjustment seat 31, and the cutting blade is mounted on the drive motor, thereby enabling the cutting blade to be adjusted vertically relative to the adjustment seat 31 to accommodate gaps of different depths.

[0047] Additionally, the power module 5 is electrically connected to the drive motor for power supply. The blade rotates under the drive motor and extends into the gap to clean it. In this embodiment, the blade rotates clockwise.

[0048] Furthermore, an arc-shaped baffle 33 is provided above the tool module 32, and a foreign object collection box 34 is provided on the front side of the arc-shaped baffle 33. This box is used to guide foreign objects brought up by the tool module 32 during the cleaning process into the foreign object collection box 34. Since the blade rotates clockwise, the foreign object will be lifted up behind the blade. Therefore, the opening on the rear side of the arc-shaped baffle 33 is lower, and the opening on the front side is higher. The front opening corresponds to the foreign object collection box 34, so that the foreign object can be lifted up by the blade and enter the foreign object collection box 34 along the arc-shaped baffle 33.

[0049] Furthermore, the seam cleaning mechanism 3 also includes a blower 35, which is mounted on the frame 1 between the seam filling mechanism 4 and the seam cleaning mechanism 3. The blower 35 has its air outlet facing the seam to blow out dust or debris from within it. A vacuum cleaner 621 can cover the area of ​​the blower 35, facilitating the absorption and cleaning of dust blown up by the blower 35 and preventing dust pollution. Preferably, the air outlet of the blower 35 faces the direction of travel, allowing dust to be sucked away by the vacuum cleaner 621 and reducing the likelihood of dust entering the seams to be filled later.

[0050] In a specific embodiment of this utility model, the joint filling mechanism 4 includes: an asphalt storage tank 41, a pouring regulator 42, and a heater 43. The asphalt storage tank 41 is fixedly mounted on the vehicle frame 1, with its pouring port facing downwards, corresponding to the position of the joint to be filled.

[0051] The pouring regulator 42 is located on the frame 1 near the driver's seat 2 and is used to control the opening and closing of the pouring port of the asphalt storage tank 41 and the pouring speed.

[0052] A heater 43 is installed inside the asphalt storage tank 41 to maintain a constant temperature inside the tank, prevent the asphalt from solidifying, maintain its fluidity, and improve the efficiency of joint pouring. The heater 43 is electrically connected to a control module and can be controlled via a control board. In this embodiment, the heater is a heating wire assembly.

[0053] In addition, a thermometer 44 is installed on the asphalt storage tank 41 to measure and display the temperature inside the asphalt storage tank 41 in real time, and to adjust the heating temperature of the heater 43 according to the temperature.

[0054] In a specific embodiment of this utility model, the bottom of the frame 1 has multiple electric drive wheels 11. The electric drive wheels 11 are electrically connected to the control module on the frame 1 to control the operation of the electric drive wheels 11, realize the walking and stopping of the frame, and control the walking speed.

[0055] In addition, the power module 5 is electrically connected to the electric drive wheel 11 to provide driving power to the electric drive wheel 11.

[0056] The above description is merely an illustrative embodiment of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
