Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pavement construction, and specifically relates to a concrete pavement grooving device, which is mainly used in house construction and municipal cement concrete pavement construction projects. Background Art

[0002] At present, the cement concrete pavement for housing construction and municipal construction is a pavement with cement concrete as the main material for the surface layer, referred to as concrete pavement, also known as rigid pavement, commonly known as white pavement, which is a high-grade pavement. The smooth pavement makes the wheels lack sufficient adhesion. When the car is driving in rainy and snowy days or emergency braking or turning, the wheels are prone to idling or slipping, which is very likely to cause safety problems between motor vehicles and residents in residential areas. Therefore, in order to increase the adhesion of the pavement, it is necessary to use grooving construction tools to construct anti-skid grooving on the road surface during road construction. In order to ensure the quality and efficiency of construction and improve construction efficiency, technical innovation of concrete pavement grooving equipment is required.

[0003] Because traditional concrete pavement grooving equipment is too large, it is inconvenient to install and operate. In addition, the road space in the community is small and there are many turning angles, so it is difficult for large grooving devices to easily enter the area to be operated. In addition, the existing devices require more manpower to assist in the installation of grooving components, and the inconvenience of disassembling and replacing grooving components often occurs, affecting the efficiency of grooving operations. In addition, during the grooving operation, the roller and the grooving surface are easily adhered to unsolidified concrete particles. If they are not cleaned in time, the concrete particles will rotate with the roller, affecting the quality and neatness of the road grooving. This has become one of the urgent problems to be solved for community road construction projects that pursue meticulousness. Utility Model Content

[0004] In view of this, the utility model provides a concrete pavement grooving device which is easy to install and operate, meets the grooving requirements of narrow road pavements, and expands the application scope of the grooving device.

[0007] A roller is mounted outside the central shaft, and the roller can rotate along the axis of the central shaft;

[0008] A plurality of annular groove steels are distributed at intervals along the axial direction of the central axis on the outer circumferential surface of the roller for pressing grooves on the concrete pavement;

[0009] One end of the push rod is connected to the support plate, and the other end serves as a handheld end.

[0010] Preferably, an arc-shaped bracket with its inner concave surface facing downward is connected to the front side of the support plate, and a first cleaning brush is longitudinally arranged on the front end surface of the arc-shaped bracket.

[0011] Preferably, a second cleaning brush is longitudinally provided on the bottom surface of the support plate, and the second cleaning brush is located between the support plate and the roller, and is used for cleaning the surface of the roller and the annular groove steel.

[0027] The utility model will be further described below in conjunction with the accompanying drawings: It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the present invention is not limited to the embodiments described in the specific implementation methods, and any other implementation methods derived by those skilled in the art based on the technical solution of the utility model also fall within the scope of protection of the utility model.

[0028] like Figure 1 and Figure 2 As shown, a concrete pavement groove pressing device includes a support plate 1, a central shaft 4 and a push rod 3; ears 5 are provided on both sides of the length direction of the lower end surface of the support plate 1, and the central shaft 4 is connected between the two ears 5. A roller 2 is mounted on the outer side of the central shaft 4, and the roller 2 can rotate along the axis of the central shaft 4. The central shaft 4 is fixed to the ears 5 by a fastener. As an example, the fastener is a butterfly nut 41, which is sleeved on a threaded rod (external thread structure) provided at both ends of the central shaft 4. The butterfly nut 41 is matched with the external threads at both ends of the central shaft 4, so that the roller 2 and the central shaft can be detachably installed.

[0029] A plurality of annular groove steels 21 are axially spaced apart on the outer circumferential surface of the roller 2 along the central axis 4 for grooving the unsolidified concrete pavement. As an example, the spacing between adjacent annular groove steels 21 is different and can be set according to the requirements of the pavement groove size, so that the device can meet the requirements of grooving different pavements.

[0030] An arc-shaped bracket 11 is fixedly connected to the front side of the support plate 1, with the inner concave surface of the arc-shaped bracket 11 facing downward, and a front bracket is provided on the front end face of the arc-shaped bracket 11 (the end face of the arc-shaped bracket 11 connected to the support plate 1 in the circumferential direction is the rear end face, and the other end face is the front end face), and a first cleaning brush 6 is longitudinally provided on the front end face for surface cleaning of grooved or ungrooved concrete pavement, which can not only remove residual concrete particles on the ungrooved pavement, but also perform secondary cleaning on the grooved pavement.

[0031] A second cleaning brush 7 is longitudinally arranged on the bottom surface of the support plate 1, and the second cleaning brush 7 is located between the support plate 1 and the roller 2, and is used to clean the roller 2 and the surface of the annular groove steel 21, and remove the concrete particles adhering to the surface of the roller 2 and the annular groove steel 21, so as to ensure the quality and neatness of the groove. As an example, according to the construction road surface conditions, the brush head of the first cleaning brush 6 is made of soft plastic material; the brush head of the second cleaning brush 7 is made of steel wire material.

[0032] One end of the push rod 3 is connected to the support plate 1, and the roller 2 is pushed and pulled by pushing and pulling the support plate 1; the other end of the push rod 3 is used as a handheld end. As an example, the push rod 3 is made of aluminum alloy or plastic material, which serves to reduce the weight of the device and improve the operability of the device.

[0033] Handles 8 are provided at both ends of the support plate 1 in the length direction for conveniently lifting the entire device. As an example, the handle 8 is a steel bar or a steel ring. Welding technology is used between the handle 8 and the support plate 1 and between the support plate 1 and the support ear 5 to ensure that the handle 8 can be firmly connected to the support plate 1, so that the operator can easily transfer the device to other areas to be worked after completing the grooving operation of a section of the road surface.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
