[0002] Cement concrete floors are smoother than asphalt pavements. Therefore, in order to improve the anti-slip performance of concrete floors, increase the friction between tires and the road surface, and improve driving safety on concrete roads, the surface layer of the concrete floor needs to be textured and grooved.

[0003] The traditional concrete graining process is: after the concrete pavement is plastered, when the index finger slightly presses the concrete surface and a dent about 2mm deep appears, it is the best graining time. The graining depth is mostly 1-2mm. The graining device used is a simple combination of a grain puller and a long bamboo pole, which uses the grain puller's own weight, manual thrust and pressure to achieve the graining effect.

[0004] The above-mentioned artificial concrete graining construction process is too old, and the grains produced are generally uneven, not straight, and the depth of the grain is not uniform. In addition, the graining construction of concrete pavement often occurs before the final setting of concrete. At this time, the construction workers are likely to leave footprints on the pavement surface when they are doing graining construction on the concrete pavement, affecting the overall aesthetics of the concrete floor. Therefore, it is urgent to find an automated concrete graining device to speed up the construction speed of concrete floor graining and ensure the uniformity of the concrete floor texture and the surface aesthetics.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown, the utility model provides a concrete floor texture drawing trolley, and its structure mainly includes: a counterweight block 1, an adjusting screw rod 2, a rear drive device 3, a texture drawing roller 4, an engine compartment 5, a front drive device 6, a trowel 7, a transmission shaft 8, a transmission gear 9, a frame 10, and a crawler 11. The trowel 7 is arranged at the front of the frame 10, which is equivalent to the front support of the trolley; the texture drawing roller 4 is arranged at the rear of the frame 10, which is equivalent to the rear wheel of the trolley. The engine compartment 5 is located inside the frame 10, and is used to install the rear drive device 3 and the front drive device 6.

[0026] The power drive of the grain drawing trolley is divided into a front drive device 6 and a rear drive device 3. The front drive device 6 controls the trowel machine 7 to rotate and level the floor. The rear drive device 3 provides forward power for the grain drawing roller 4. The front drive device 6 provides kinetic energy to the two trowel machines 7 through the transmission shaft 8. The rear drive device 3 serves as a driving wheel and is connected to the grain drawing roller 4 through a crawler track 11.

[0027] Two trowel machines 7 are installed on the grain drawing trolley to level the surface of the concrete pavement. The two trowel machines 7 are on the same horizontal line. The power is driven by the front drive device 6 to drive the transmission gears 9 on both sides, and then the transmission gears 9 transmit the power to the trowel machines 7 through the transmission shaft 8. The rotation directions of the trowel machines 7 are one clockwise and the other counterclockwise, so as to balance the horizontal force of the grain drawing trolley.

[0028] The graining roller 4 includes a graining knife 41, an axle 42, a driven wheel 43, an anti-slip washer 44, a rubber ring 45, and a limiting nut 46. The positional relationship of the various components is that the axle 42 is fixedly sleeved in the driven wheel 43, the graining knife 41 is sleeved on the driven wheel 43, and a rubber ring 45 that is not prone to rolling or sliding is sleeved between the two graining knives 41. Finally, the entire graining roller is fixed into a whole by tightening the limiting nut 46.

[0029] The graining knives 41 are equidistantly distributed and the spacing between the graining knives 41 can be changed by replacing rubber rings 45 of different widths, and the preferred distance is 20 mm; the driven wheel 43 is connected to the rear drive device 3 through the track 11 to provide forward kinetic energy for the entire graining trolley, and at the same time, in order to prevent the track 11 from slipping and ensure the transmission efficiency of the rear drive device 3, a circle of anti-skid washers 44 is also provided on the driven wheel 43; an adjusting screw 2 is installed at each end of the wheel axle 42. After the concrete pavement is leveled, the height of the graining roller 4 can be adjusted according to the floor layout elevation to ensure that the pavement graining depth is consistent with the design drawing.

[0030] Each graining trolley is equipped with a plurality of counterweight blocks 1, the mass range of the counterweight blocks 1 is between 2.5kg and 10kg. By increasing or decreasing the number of counterweight blocks 1, the weight of the graining trolley itself can be changed at will, which enables the graining trolley to meet the dimensional requirements of graining depth for concrete pavements of different strengths and types, thereby improving the applicability of the graining trolley.

[0031] The use process of the utility model is carried out according to the following steps:

[0032] S1: Measurement and layout. Introduce the ground elevation and center line from the off-site control network to the structural wall or column, measure the +50cm elevation point of the building ground according to the elevation, and strictly determine the ground water flow direction and floor surface thickness according to the design drawings, which is the basis for the leveling of the floor concrete.

[0033] S2: Preparation for pavement texture drawing. In order to achieve good texture drawing effect of concrete floor, the concrete floor must be poured densely, and the concrete slump must be strictly controlled between 140-160mm. If the slump is too large, the shaping effect of the texture bottom and the groove wall will be poor. If the slump is too small, the floor leveling and finishing effect will be poor, texture drawing will be difficult, and the texture drawing knife will be worn out.

[0034] S3: Surface treatment. Chisel off the concrete around the floor and the wall where the mold is running or the concrete is leaking, clean it up, and clear all the materials and debris in the construction area, then use a concrete trowel to fully level the floor surface.

[0035] S4: Determine the drawing time. The drawing construction of concrete floor should be arranged within 4-5 days after the initial setting of concrete. When the index finger presses the concrete surface with a little force and a dent of about 2mm in depth appears, it is the best drawing time. The drawing depth should be strictly controlled at 1-2mm.

[0036] S5: Installation of the graining machine. First, according to the construction design requirements and actual use requirements, the spacing of the floor graining is determined to be 4-5mm, and on this basis, the graining knife 41 is installed; then the trowel 7 at the front end of the graining trolley is installed, ensuring that the two trowels 7 are on the same horizontal plane, and the flatness of the surface of the trowel 7 is checked; finally, in combination with the requirement of 1-2mm graining depth of the concrete floor, a suitable counterweight 1 is added to the graining trolley.

[0037] S6: Graining of concrete floor. According to the concrete floor elevation requirements and graining depth requirements, the height of the graining roller 4 is adjusted. The height of the graining roller 4 is controlled by two adjusting screws 2. After the height of the graining roller 4 is adjusted to the appropriate position, the power can be turned on to conduct a trial graining test. The graining construction should strictly control the texture depth to ensure one-time graining and simultaneously check the graining forming quality. If the forming quality of a local area is poor, the surface should be re-grained to ensure that the graining of the entire floor is uniform, straight, and the ground is smooth.

[0038] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
