Description

Technical Field

[0001] This utility model relates to the field of road texturing, specifically to a concrete road texturing device. Background Technology

[0002] Concrete pavement texturing refers to creating texturing grooves of a certain depth and width on concrete pavement using a texturing tool. Its main function is to increase the friction coefficient of the concrete pavement and improve its anti-skid properties.

[0003] When using a manual texturing tool to texture concrete pavement, the operator holds the handle and drives the front-end texturing wheel to roll longitudinally along the concrete pavement. Multiple annular raised patterns on the surface of the texturing wheel are used to press and form texturing grooves. During the repeated and staggered pulling process of the texturing tool, there is no reference standard, and the operation can only rely on the operator's skill. The straightness of the texturing grooves formed by the repeated pulling is not high, which affects the quality of the texturing grooves. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a concrete road textured surface device.

[0005] This utility model is achieved through the following technical solution:

[0006] A concrete road texturing device includes a support frame for the texturing device and a texturing wheel that is rotatably supported at its lower part. A Z-shaped frame is fixed on the support frame at the outer end of one side of the texturing wheel. A guide wheel matching a straightedge is installed on the Z-shaped frame. The straightedge is supported on the upper part of the outer template of the concrete road surface.

[0007] Alternatively, a guide block with a flat bottom is fixed to the lower end of the side of the ruler, and a guide groove matching the guide wheel is opened on the guide block.

[0008] Alternatively, the center distance between the guide wheel and the annular embossing wheel on the adjacent side is the same as the center distance between the two adjacent annular embossing wheels.

[0009] Alternatively, when the embossed wheel is supported on the concrete pavement, the guide wheel on its side fits into the bottom of the guide groove.

[0010] Alternatively, the upper sides of the guide groove are provided with outwardly expanding bevels.

[0011] Alternatively, two strip-shaped viewing holes are symmetrically opened at both ends of the guide groove, the width of which is smaller than the width of the guide wheel.

[0012] Compared with existing technologies, the advantages of this utility model are: by installing equidistant guide wheels on one side of the embossing wheel, the embossing groove is pressed by the guide wheels rolling in a straight line in the guide groove on the side of the ruler, resulting in better straightness and more uniform spacing of the embossed groove, which greatly improves the appearance quality of the embossed groove.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 As shown, a concrete road texturing device includes a support frame 2 for the texturing device and a texturing wheel 1 for its lower rotating support. A Z-shaped frame 3 is fixed on the support frame 2 at one outer end of the texturing wheel 1. A guide wheel 5 matching a straightedge 6 is installed on the Z-shaped frame 3. The straightedge 6 is supported on the upper part of the outer template 10 of the concrete road surface 11.

[0020] like Figure 1 , 2 As shown, a guide block 7 with a flat bottom is fixed to the lower side of the straightedge 6. The straightedge 6 and the guide block 7 are machined as a whole and made of aluminum alloy, which is lighter and has better resistance to deformation. The guide block 7 has a guide groove 8 that matches the guide wheel 5.

[0021] like Figure 3 As shown, the center distance between the guide wheel 5 and the annular embossed 101 of the embossing wheel 1 on the adjacent side is the same as the center distance between the two adjacent annular embossed 101. This ensures that the spacing between adjacent embossed grooves 12 is more uniform when the adjacent embossed grooves 12 are staggered.

[0022] like Figure 4As shown, when the embossing wheel 1 is supported on the concrete pavement 11, the guide wheel 5 on its side is in contact with the bottom of the guide groove 8. In this way, the guide groove 8 will not support or lift the embossing wheel 1, thus ensuring the flatness of the embossing wheel 1.

[0023] like Figure 4 As shown, the upper sides of the guide groove 8 are provided with outwardly expanding angles 9, which makes it easier for the guide wheel 5 to enter the guide groove 8.

[0024] Two strip-shaped viewing holes are symmetrically opened at both ends of the guide groove 8. The width of the strip-shaped viewing hole is smaller than the width of the guide wheel 5. The outermost textured groove 12 can be seen through the viewing hole, so as to achieve precise adjustment of the straightedge 6.

[0025] The implementation principle of a concrete road texturing device according to an embodiment of this application is as follows:

[0026] First, place the straightedge 6 vertically along the concrete pavement 11. Place the guide wheel 5 on the side of the embossing wheel 1 inside the guide groove 8 of the guide block 7. Hold the handle and pull the embossing wheel 1. Through the guiding action of the guide wheel 5 in the guide groove 8, the embossed groove 12 pulled out has better straightness.

[0027] When the operator pulls the embossing wheel 1 to roll along the concrete pavement 11 to form the first cycle of embossed groove 12, the straightedge 6 is placed on the upper part of the outermost embossed groove 12 and supported by the outer template 10. After support, the position of the straightedge 6 is adjusted so that the guide groove 8 on one side guide block 7 is directly above the outermost embossed groove 12. During adjustment, it can be observed through the strip-shaped viewing holes on both sides of the guide groove 8.

[0028] After adjusting the position, place the guide wheel 5 of the embossing wheel 1 into the guide groove 8 and pull and press to form the embossed groove 12. In this way, the embossed groove 12 drawn out by the cyclic staggered drawing has better straightness, and the spacing of the embossed groove 12 drawn out by different cycles is more uniform, which greatly improves the appearance quality of the embossed groove 12.
