Description

Technical Field

[0001] The present application relates to the field of municipal construction technology, and in particular to a municipal road construction equipment. Background Art

[0002] " "Road" refers to highways, urban roads and places under the jurisdiction of units but where social motor vehicles are allowed to pass, including squares, public parking lots and other places for public passage. Cracks will occur during the long-term use of municipal roads. Therefore, it is necessary to use automatic caulking devices to caulk and repair the cracks. There are also some caulking devices in the prior art to repair cracks. For example, the patent with application number CN202122700849.8 discloses a road caulking device for municipal road construction. The road caulking device for municipal road construction is equipped with a structure of an interlayer plate, a drainage hole, a servo motor, a connecting rod, a push rod, a piston plate, etc. The grouting liquid flowing from the upper part of the box into the lower fixed chamber can be quantitatively pushed out by the piston plate, and the gap can be quantitatively filled with glue by controlling the servo motor, thus avoiding the waste of materials caused by random glue filling, greatly saving resources, and facilitating the control of construction costs. However, when using this solution, firstly, the dust and impurities in the gap cannot be cleaned during grouting, and the dust and impurities after grouting will affect the grouting quality; secondly, since the cracks are generally irregular in shape, the filling device cannot accurately or precisely follow the extension direction of the cracks and automatically adjust, and manual adjustment is required, which is inconvenient to use. Utility Model Content

[0003] The embodiment of the present application provides a municipal road construction equipment, which can automatically follow the extension direction of the cracks and adaptively and accurately fill the cracks, and can improve the quality of the road filling.

[0004] The embodiment of the present application provides a municipal road construction equipment, which includes a base, a caulking mechanism and a cleaning mechanism, wherein a moving wheel is arranged at the bottom of the base; the caulking mechanism is arranged on the base, and the caulking mechanism is used to spray the hot-melted caulking material into the cracks in the road surface; the cleaning mechanism is arranged at the bottom of the base, and the cleaning mechanism is used to clean the inside of the cracks in the road surface; wherein the cleaning mechanism is closer to the front side of the base than the caulking mechanism, and the cleaning mechanism includes a first adjusting component, a blowing part and a cleaning component, the first adjusting component includes a first mounting plate and a first movable seat, the first mounting plate is provided with a first slide groove extending in the left and right directions, the first movable seat is slidably matched with the first slide groove, the cleaning component is installed at the middle position of the first movable seat, the blowing part is arranged on the first movable seat and is located on one side of the cleaning component, and the first mounting plate is liftably installed at the bottom of the base through a first telescopic device so that the cleaning component can partially extend into the crack.

[0005] In this solution, a cleaning mechanism is provided on the base, and the cleaning mechanism is closer to the front side of the base than the caulking mechanism, so that the dust and impurities in the cracks of the road surface can be cleaned. Since the cleaning mechanism includes a blowing component and a cleaning assembly, the cleaning assembly can clean the dust in the cracks so that the dust is separated from the cracks, and the blowing component can blow the dust and impurities remaining in the cracks and brushed out by the cleaning brush outward, which has a better effect. Therefore, under the dual effects of the blowing component and the cleaning assembly, the cleaning efficiency of the dust and impurities in the cracks is greatly improved, ensuring that no dust and impurities remain in the cracks of the road, avoiding that the dust and impurities after caulking will affect the caulking quality, and workers do not need to clean the dust and impurities, which reduces the workload of workers. Furthermore, the cleaning mechanism includes a first adjusting component. Since the cracks in the road are of irregular shapes and have different curvatures, the movable seat in the first adjusting component is slidably arranged on the first mounting plate, and the blowing component and the cleaning component are mounted on the first movable seat. When the municipal road construction equipment is used, the first telescopic device allows the cleaning component to partially extend into the crack. During the forward movement of the equipment, since the cleaning component can partially extend into the crack, the two are plugged in and matched, and the curvature of the crack will guide the first movable seat to adaptively slide on the first mounting plate, so that the cleaning mechanism can adaptively follow the direction of the crack, always achieve accurate positioning of the crack, and is not prone to detachment from the crack. There is no need for manual adjustment or adjustment of the equipment to adapt to the crack. The equipment has a strong adaptive ability, and the structure of the cleaning mechanism is correspondingly simplified, thereby reducing the construction cost and subsequent maintenance costs.

[0006] In some embodiments, the cleaning component includes a driving motor and a cleaning brush. The driving motor is installed on the first movable seat. The driving end of the driving motor is connected to the cleaning brush to drive the cleaning brush to rotate along its axial direction and clean the dust in the cracks. The axial direction of the cleaning brush is set in the same direction as the vertical direction. The air outlet of the blowing component is facing the direction of the cleaning brush. The blowing component is used to cooperate with the cleaning brush to clean and blow out the dust in the cracks of the road surface.

[0007] In the above technical solution, the cleaning brush can rotate along its axial direction under the action of the driving motor, so that the cleaning brush can rotate and clean the dust in the cracks, so that the dust is separated from the cracks. With the cooperation of the blowing component and the cleaning brush, the dust and impurities remaining in the cracks and brushed out by the cleaning brush can be blown out.

[0008] In some embodiments, the number of the blowing components is set to two, and the two blowing components are distributed on both sides of the cleaning brush along the left-right direction of the base.

[0009] In the above technical solution, by setting the number of blowing components to two, and the two blowing components are respectively located on both sides of the cleaning brush, the cleaning effect of dust in the crack can be further improved.

[0010] In some embodiments, buffer components are provided at both ends of the first slide groove in the length direction.

[0013] In the above technical solution, it takes a certain amount of time for the caulking material to solidify and harden after entering the cracks in the road surface. In order to increase the solidification speed of the caulking material, a drying mechanism is provided on the base. The drying mechanism can quickly dry out the moisture in the caulking material that enters the cracks, thereby accelerating the solidification of the caulking material and preventing external impurities from mixing into the caulking material before it hardens, thereby affecting the quality of crack repair.

[0014] In some embodiments, the drying mechanism includes a hot air blower and a hot air pipe. The hot air blower is installed on a base.

[0015] In the above technical solution, hot air can be generated by a hot air blower, and the hot air can be transported and blown toward the crack using a hot air pipe, thereby accelerating the drying of the caulking material introduced into the crack and reducing the time required for the caulking material to solidify.

[0016] In some embodiments, the number of hot air ducts is set to multiple, and the multiple hot air ducts are connected to the air outlet end of the hot air blower through the air supply duct, and the multiple hot air ducts are distributed at intervals along the left and right directions of the base.

[0017] In the above technical solution, the number of hot air pipes is set to multiple, and the multiple hot air pipes are distributed on the base along the left and right directions. In this way, when the equipment is running, even if the crack changes due to bending or irregular changes, with the cooperation of the multiple hot air pipes, the left and right directions of the base can almost be covered, that is, at least one hot air pipe can blow air toward the crack.

The cleaning mechanism 20 is arranged at the bottom of the base 10, and the cleaning mechanism 20 is used to clean the inside of the cracks of the road surface. Among them, the cleaning mechanism 20 is closer to the front side of the base 10 than the caulking mechanism 30. The cleaning mechanism 20 includes a first adjustment component, a blowing component 22 and a cleaning component. The first adjustment component includes a first mounting plate 51 and a first movable seat 52. The first mounting plate 51 has a first slide groove 53 extending in the left and right directions. The first movable seat 52 is slidably matched with the first slide groove 53. The cleaning component is installed in the middle position of the first movable seat 52. The blowing component 22 is arranged on the first movable seat 52 and is located on one side of the cleaning component. The first mounting plate 51 can be lifted and lowered at the bottom of the base 10 through a first telescopic device 70, so that the cleaning component can be partially extended into the crack.

[0039] In this solution, by providing a cleaning mechanism 20 on the base 10, and the cleaning mechanism 20 is closer to the front side of the base 10 than the caulking mechanism 30, the cleaning mechanism 20 can clean the dust and impurities in the cracks of the road surface, and because the cleaning mechanism 20 includes a blowing component 22 and a cleaning assembly, the cleaning assembly can clean the dust in the cracks so that the dust is separated from the cracks, and the blowing component 22 can blow the dust and impurities remaining in the cracks and brushed out by the cleaning assembly outward, which has a better effect. Therefore, under the dual effects of the blowing component 22 and the cleaning assembly, the cleaning efficiency of the dust and impurities in the cracks is greatly improved, ensuring that no dust and impurities remain in the cracks of the road, avoiding that the dust and impurities after caulking will affect the caulking quality, and workers do not need to clean the dust and impurities, reducing the workload of workers. In addition, the cleaning mechanism 20 includes a first adjusting component. Since the cracks in the road are of irregular shapes and have different curvatures, the first movable seat 52 in the first adjusting component is slidably set on the first mounting plate 51, and the blowing component 22 and the cleaning component are installed on the first movable seat 52. When the municipal road construction equipment is used, the first telescopic device 70 allows the cleaning component to partially extend into the crack. As the equipment moves forward, since the cleaning component can partially extend into the crack, the two are plugged in and matched, and the curvature of the crack will guide the first movable seat 52 to slide adaptively on the first mounting plate 51, so that the cleaning mechanism 20 can adapt to the direction of the crack, always achieve accurate positioning of the crack, and is not easy to be separated from the crack. There is no need for manual adjustment or adjustment of the equipment to adapt to the crack.

In this embodiment, the first telescopic device 70 can be an electric push rod, and the first telescopic device 70 can adjust whether the cleaning brush is inserted or not and the insertion length after deepening, so that the cleaning mechanism 20 can be suitable for cleaning road cracks of different depths, and the application range is wider. In addition, a driving device can be provided on the base 10, and the driving device can drive the moving wheel to rotate, so as to realize the walking of the equipment. Of course, a push rod 12 is provided on the rear side of the base 10, and the push rod 12 can be used by external staff to push the device forward or backward.

[0041] In some embodiments, the cleaning assembly includes a driving motor 23 and a cleaning brush 24. The driving motor 23 is mounted on the first movable seat 52. The driving end of the driving motor 23 is connected to the cleaning brush to drive the cleaning brush 24 to rotate along its axis and clean the dust in the cracks. The axis of the cleaning brush 24 is arranged in the same direction as the vertical direction. The air outlet of the blowing component 22 faces the direction of the cleaning brush 24. The blowing component 22 is used to cooperate with the cleaning brush 24 to clean and blow out the dust in the cracks of the road surface. The cleaning brush 24 can rotate along its axis under the action of the driving motor 23, so that the cleaning brush 24 can rotate and clean the dust in the cracks, so that the dust is separated from the cracks. With the cooperation of the blowing component 22 and the cleaning brush 24, the dust impurities remaining in the cracks and brushed out by the cleaning brush 24 can be blown out.

[0042] Exemplarily, the number of the blowing components 22 is set to two, and the two blowing components 22 are distributed on both sides of the cleaning brush 24 along the left-right direction of the base 10. By setting the number of the blowing components 22 to two, and the two blowing components 22 are respectively located on both sides of the cleaning brush 24, the cleaning effect of the dust in the crack can be further improved.

[0048] It should be noted that the drying mechanism 40 is not provided with an adjustment component, but adopts a covering blowing method to dry the cracks. Although this will waste some hot air, it can simplify the structure of the drying mechanism 40 and is conducive to cost control.

[0049] In some embodiments, along the front-to-back direction of the base 10, the caulking mechanism 30 is located in the middle of the base 10, and the cleaning mechanism 20 and the drying mechanism 40 are respectively located on both sides of the front-to-back direction of the base 10, and the cleaning mechanism 20 is located on the front side of the base 10, and the drying mechanism 40 is located on the back side of the base 10.

[0053] The feeding pump 34 provides power, and the caulking material is delivered to the caulking gun 33 under the transmission action of the feeding hose 35, and discharged from the caulking gun 33 into the crack to complete the road repair. In order to ensure that the caulking gun 33 is always accurately positioned in the crack without being affected by the irregularity of the crack, a second adjustment component 60 is provided. As the equipment moves forward, under the action of the second telescopic device 71, the caulking gun 33 can partially extend into the crack.
