Description

Technical Field

[0001] This invention relates to the field of cement concrete pavement construction technology, and particularly to cement concrete pavement roughening equipment and methods. Background Technology

[0002] The current method of cement concrete pavement construction requires roughening treatment. Roughening treatment is a construction method, mainly to increase the anti-skid performance of the pavement. Cement concrete pavement is smoother than asphalt pavement and has poor anti-skid performance. Roughening can increase the friction between the tire and the pavement and improve the anti-skid performance of the pavement. Especially when the air humidity is relatively high, cement concrete pavement is in a damp state or a thin water film state for a long time, which greatly reduces the adhesion of tires and drastically reduces the anti-skid performance, which is one of the main causes of traffic accidents.

[0003] However, there is a lack of specialized roughening equipment for creating textured grooves on cement concrete pavements. Generally, materials such as hemp or canvas are used. These materials are fibrous and have a strong affinity for cement; if not cleaned promptly, they tend to stick together, resulting in insufficient depth and uniformity of the roughened grooves. Ultimately, the roughened grooves on the cement concrete pavement are worn away almost completely within a very short time after the road is opened to traffic. In the prior art, Chinese invention patent application, publication number CN109440606A, entitled "Cement Concrete Road Surface Texture Equipment and Method", discloses a cement concrete road surface texture equipment, including a texture brush, an angle holding frame, and a moving device. The texture brush has bristles and is mounted on the angle holding frame, which is used to maintain the angle between the bristles and the cement concrete road surface. The angle holding frame is mounted on the moving device, which is used to move the angle holding frame on the cement concrete road surface. The main problems with existing technologies are: low efficiency of roughening construction, high demand for manual labor, and the depth and movements of roughening are almost entirely controlled by manual labor, lacking automated equipment and large-scale construction methods.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0018] This invention aims to address the technical problem of the lack of dedicated and efficient equipment for large-scale texturing operations in the prior art. Firstly, it requires the design of equipment suitable for continuous construction. Please refer to the appendix for details of this technical solution. Figure 1-6 As shown, the cement concrete pavement roughening equipment provided by this technical solution includes: The precast track 10 is erected on the cement concrete pavement 1 to be roughened. The precast track 10 is actually used to cover a certain area of ​​the pavement 1 to be roughened. That is, the entire pavement is divided into multiple construction units by means of local and step-by-step construction. After the precast track 10 is erected, the walking mechanism 20 is connected to the precast track 10. That is, the walking mechanism 20 is set on the precast track 10 and can walk along the direction of the precast track 10. That is, the walking mechanism 20 can pass through the pavement 1 to be roughened. The roughening roller assembly 30 is connected to the walking mechanism 20 and moves with the walking direction of the walking mechanism 20. Specifically, the texturing operation is completed by the texturing roller assembly 30, which has a texturing roller 301. The texturing roller assembly 30 can periodically drive the texturing roller 301 to move up and down. When it moves down to the limit, because multiple texturing teeth 302 are constructed on the outer diameter of the texturing roller 301, the texturing teeth 302 of the texturing roller 301 periodically contact the surface 1 to be texturized, so that texturing marks can be formed on the surface 1 to be texturized. Multiple roughening teeth 302 are constructed on the outer diameter of the roughening roller 301. The roughening teeth 302 are in the shape of a ring and are perpendicular to the axis of the roughening roller 301. They are arranged in parallel in the radial direction of the roughening roller 301. The roughening marks are formed by the travel marks along the travel mechanism 20. Moreover, the roughening roller assembly 30 not only has the limit position for forming marks on the road surface, but its up and down movement also makes the actual roughening marks vary in depth. This actually matches the characteristics of the road surface, that is, the road surface itself has a certain curvature during actual construction and is not straight. When the roughening of the area is completed, that is, when the roughening of the road surface 1 of the current construction unit is completed, the prefabricated track 10 is moved to the next construction unit as a whole, so that repeated construction can be achieved. The advantage of this technical solution is that the roughening operation is completely completed by equipment, eliminating the need for manual roughening, and the construction area and scope are large, with a high degree of automation.

[0019] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figures 3 and 6, the prefabricated track 10 includes: Track frame 110; The track frame 110 is provided with four corners with traveling wheels 111, and fixed piles 112 are provided on the traveling wheels 111 for fixing the track frame 110. The fixed piles 112 mainly serve to fix the track frame 110. The traveling wheels 111 enable the entire prefabricated track 10 to move and travel. It can be moved by a trailer or engineering vehicle, which makes it more convenient when repeatedly constructing construction units. It does not require repeated laying of tracks. That is, the prefabricated track 10 itself is movable and can be fixed at any time. Specifically, the track frame 110 includes two sets of parallel long side frames 113 arranged along the length direction.

[0020] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figures 3 and 6, in a more detailed configuration, a track body 114 is mounted above each set of long frame 113; in a cross-sectional view, the track body 114 forms a track groove 115, which is used to cooperate with the setting of the walking mechanism 20. In one specific embodiment, please refer to Figure 1 , 2 As shown in Figure 3, the traveling mechanism 20 includes: a traveling body 210, which is arranged horizontally; and two track wheels 220 are provided on both sides below the traveling body 210, with the track wheels 220 connected to the track groove 115.

[0021] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figure 3, the walking principle is as follows: a walking motor 211 is connected to the top of the walking vehicle body 210 via a support frame 260; the output shaft of the walking motor 211 is perpendicular to the walking vehicle body 210 and is connected to an actuating gear 212; the actuating gear 212 meshes with a transmission gear 213. A transmission gear 213 is connected to the first end of a rotating shaft 214; the second end of the rotating shaft 214 is rotatably connected to a rotating shaft seat 215; the rotating shaft seat 215 is fixedly connected to the vehicle body 210, such that the rotating shaft 214 is perpendicular to the vehicle body 210 and parallel to the axis of the travel motor 211; and an auxiliary shaft seat 216 is connected to the side of the vehicle body 210, and a travel shaft 217 is rotatably connected to the auxiliary shaft seat 216. The first end of the traveling shaft 217 is connected to a traveling gear 218; the traveling gear 218 meshes with the transmission gear 213; the second end of the traveling shaft 217 is connected to a mating gear 219; a traveling rack 221 is provided on one side of the track body 114 along the length of the track body 114; the mating gear 219 meshes with the traveling rack 221.

[0022] When the travel motor 211 rotates forward, due to the principle of gear meshing, the operating gear 212 and the travel gear 218 rotate in the same direction, and in conjunction with the attached... Figure 7 The configuration of the central traveling rack 221 enables the transmission to achieve travel.

[0023] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figure 3, an L-shaped extension arm 230 is provided on the side of the traveling vehicle body 210 away from the side where the auxiliary axle seat 216 is provided; L-shaped extension arm 230 extends to the side of the adjacent track body 114 and connects to a rail receiving wheel 231; the side of the track body 114 has an auxiliary rail receiving groove 232 that travels along the length of the track body 114; the rail receiving wheel 231 is rail-connected in the auxiliary rail receiving groove 232. The above configuration serves two main purposes: the L-shaped extension arm 230 acts as a counterweight to ensure the balance of the traveling vehicle body 210, mainly because the traveling motor 211 is located on the other side of the traveling vehicle body 210; secondly, the rail-connecting wheel 231 is connected to the auxiliary rail-connecting groove 232, making the travel smoother and preventing jamming.

[0024] In one specific embodiment, please refer to Figure 4 , 2 As shown in Figure 3, the brushing roller assembly 30 includes: a connecting plate 303, which is detachably fixed to the lower part of the vehicle body 210; two sets of first shaft brackets 310, which are vertically connected to the lower part of the connecting plate 303; and a first drive shaft 311, which is rotatably connected to the first shaft brackets 310. One end of the first drive shaft 311 extends out of the first shaft bracket 310 and connects to the output end of a drive motor 420; The drive motor 420 is connected to a motor mounting plate 421; the motor mounting plate 421 is perpendicularly connected to the vehicle body 210; an eccentric cam 330 is fixedly connected to the center of the first drive shaft 311.

[0025] The brushing roller assembly 30 further includes: two sets of second shaft brackets 320 connected by a balance beam 321; the first ends of the two sets of second shaft brackets 320 are rotatably connected to the two ends of the brushing roller 301; the second end of each set of first shaft brackets 310 is connected to a guide post 341; the first end of each set of second shaft brackets 320 is provided with a guide hole 342, and the guide post 341 can be inserted into the guide hole 342; A rotating abutment wheel 343 is provided on the balance beam 321, which can abut against the eccentric cam 330.

[0026] It also includes: A tensioning assembly is used to drive the brushing roller 301 to rotate when the first drive shaft 311 rotates, so that the rotating abutment wheel 343 can maintain contact with the eccentric cam 330; one end of the first drive shaft 311 is connected to a first tensioning wheel 501; one end of the brushing roller 301 is connected to a second tensioning wheel 502; a first rotating arm 510 is rotatably connected to the first tensioning wheel 501 and an intermediate wheel 503; a second rotating arm 520 is rotatably connected to the second tensioning wheel 502 and the intermediate wheel 503; a first tensioning belt 601 is radially connected to the first tensioning wheel 501 and the intermediate wheel 503; a second tensioning belt 602 is radially connected to the second tensioning wheel 502 and the intermediate wheel 503.

[0027] The working principle and process of the brushing roller assembly 30 are as follows: When the drive motor 420 rotates clockwise, the eccentric cam 330 rotates accordingly and continuously abuts against the eccentric cam 330, thereby realizing the reciprocating motion of the guide column 341 in the guide hole 342, so that the first shaft bracket 310 and the second shaft bracket 320 reciprocate closer or further away under the action of the eccentric cam 330. In the tensioning assembly, the tensioning during the operation is achieved by the second rotating arm 520, the first rotating arm 510 and the intermediate wheel 503. The transmission of the second tension belt 602 and the first tension belt 601 causes the brushing roller 301 to rotate.

[0028] In addition, using the above-mentioned equipment also includes the following steps: Step S1: Connect the track frame 110, place the track frame 110 on the roughened road surface 1 by pushing the walking wheel 111, and then configure the walking mechanism 20. Step S2: Confirm that the textured roller 301 of the textured roller assembly 30 maintains a preset distance from the surface to be textured 1. Step S3: Start the walking motor 211 and confirm that the walking vehicle 210 can move normally; In step S4, the drive motor 420 causes the sizing roller assembly 30 to perform a reciprocating motion, so that the sizing teeth 302 of the sizing roller 301 can form sizing marks on the surface 1 to be sizing.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
