Description

Technical Field

[0001] This utility model belongs to the field of surface finishing and roughening technology for pavers, specifically relating to a surface finishing and roughening device for slipform pavers. Background Technology

[0002] Patent publication number CN217710211U discloses an automatic surface roughening device for a slipform paver. It uses a lifting mechanism to drive two connecting rods to move, so that the second connecting rod can roughen half of the road surface when it moves. Even if the construction progress on both sides of the road is different, the first or second connecting rod can be used smoothly to roughen the ground.

[0003] However, the above-mentioned surface finishing and roughening device has the following problems during use:

[0004] 1. When half of the road surface is selected for construction and the construction progress of the two halves is inconsistent, there will be a certain height difference between the two sides of the road surface. Since the height of the scraper cannot be adjusted, it is easy to cause damage to the other half of the road surface when finishing the surface of one half, so the finishing operation of the half-width cannot be completed smoothly.

[0005] 2. During the roughening process, the cement slurry needs to be added to the roughening rod manually, which is time-consuming and labor-intensive, and may result in uneven application of cement slurry on the surface of the roughening rod.

[0006] To address this, we designed a surface finishing and roughening device for slipform pavers and improved upon its shortcomings. Utility Model Content

[0007] To address the problems mentioned in the background art, this utility model provides a surface finishing and roughening device for slipform pavers, which can adjust the height of the roughening roller and scraper to achieve full-width and half-width surface finishing and roughening of the road surface, and eliminates the need for manual repeated feeding of the roughening device, thus improving the roughening efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a surface finishing and texturing device for a slipform paver, comprising a fixed mounting frame, wherein lifting and adjusting mechanisms are installed at both ends of the fixed mounting frame, and two sets of texturing devices and scraper plates that move up and down the fixed mounting frame are driven and connected through the lifting and adjusting mechanisms. The texturing device includes a texturing roller, and a plurality of texturing teeth are fixedly provided on the surface of the texturing roller. The texturing roller slides on one side of the fixed mounting frame through a lifting frame. A liquid distribution tank is connected to the top of the lifting frame, and a row of nozzles is connected to the bottom of the liquid distribution tank. A mixing cylinder and a conveying pump are installed on the top of the fixed mounting frame, and the conveying pump is connected to the liquid distribution tank through a conveying pipe.

[0009] As a preferred embodiment, the lifting adjustment mechanism includes a lead screw, which is installed inside the fixed mounting frame. The upper end of the lead screw extends out of the fixed mounting frame and is connected to a motor. A lifting plate is connected to the lead screw via a lead screw slide. The two ends of the lifting plate extend out of the through slots on the fixed mounting frame and are respectively connected to the lifting frame and the scraper plate mounting seat. The two ends of the back of the lifting frame and the scraper plate mounting seat slide on the guide rods in the sliding grooves on the front and rear sides of the fixed mounting frame via limit sliders.

[0010] As a preferred embodiment, the textured roller is installed inside the lifting frame via a rotating shaft, and the textured roller is positioned directly below the nozzle. The textured roller is adjusted in height on the fixed mounting frame via a motor-driven screw and a lifting plate.

[0011] As a preferred embodiment, the upper end of the scraper plate is mounted on the scraper plate mounting base by screws; the scraper plate is driven by a motor-driven lead screw and a lifting plate to adjust its height on the fixed mounting frame.

[0012] As a preferred embodiment, the feed end of the feed pump is connected to the mixing cylinder via a pipeline.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a lifting and adjusting mechanism to adjust the height of the surface-finishing rollers and scraper plates in the same group. It allows for selective surface finishing of one half of the road surface according to the construction progress, without affecting the other half. This ensures that even if the surface finishing times differ on both sides of the road, the surface requiring finishing can still be successfully finished.

[0015] During the surface roughening process, the fixed mounting frame drives the roughening roller to roll on the ground. The slurry is evenly sprayed onto the surface of the roughening roller through the distribution box and nozzle by the material pump. The roughening roller, in conjunction with the roughening roller, roughens the concrete ground. There is no need for manual repeated feeding of the roughening device, which makes the operation convenient, improves the roughening efficiency, and solves the problem of low efficiency of traditional manual roughening devices.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Please see Figure 1-5 This utility model provides the following technical solution: a surface finishing and roughening device for a slipform paver, including a fixed mounting frame 1. The fixed mounting frame 1 has lifting and adjusting mechanisms 2 installed at both ends on the left and right sides. Two sets of roughening devices and scraper plates 5, which are raised and lowered separately on the fixed mounting frame 1, are driven and connected by the lifting and adjusting mechanisms 2. The roughening device includes a roughening roller 4. Several roughening teeth 41 are fixedly provided on the surface of the roughening roller 4. The roughening roller 4 slides on one side of the fixed mounting frame 1 through the lifting frame 3. The lifting and adjusting mechanism 2 adjusts the height of the roughening roller 4 and scraper plate 5 in the same group. It can select to roughen half of the road surface according to the construction progress, and will not roughen the other half of the road surface. This allows for smooth surface finishing even when the surface finishing times differ on both sides of the road. The top of the lifting frame 3 is connected to a liquid distribution tank 9, and the bottom of the liquid distribution tank 9 is connected to a row of nozzles 10. The top of the fixed mounting frame 1 is equipped with a mixing cylinder 7 and a material pump 8, which is connected to the liquid distribution tank 9 via a material delivery pipe 81. The material pump evenly sprays the slurry onto the surface of the finishing roller through the liquid distribution tank and nozzles, working in conjunction with the finishing roller to finish the concrete surface. This eliminates the need for repeated manual feeding of the finishing device, making operation convenient and improving finishing efficiency.

[0025] Specifically, the lifting adjustment mechanism 2 includes a lead screw 21, which is installed inside the fixed mounting frame 1. The upper end of the lead screw 21 extends out of the fixed mounting frame 1 and is driven by a motor 22. A lifting plate 23 is connected to the lead screw 21 via a lead screw slide. Both ends of the lifting plate 23 extend out of the through slots 11 on the fixed mounting frame 1 and are respectively connected to the lifting frame 3 and the scraper plate mounting seat 6. The back ends of the lifting frame 3 and the scraper plate mounting seat 6 slide on guide rods 13 in the sliding slots 12 on the front and rear sides of the fixed mounting frame 1 via limit sliders. The textured roller 4 is installed inside the lifting frame 3 via a rotating shaft. The textured roller 4 is located directly below the nozzle 10. The textured roller 4 is powered by electricity. The motor 22 drives the lead screw 21, which is driven by the lifting plate 23 to adjust the height of the fixed mounting frame 1. The upper end of the scraper plate 5 is mounted on the scraper plate mounting seat 6 by screws. The scraper plate 5 is driven by the motor 22 to drive the lead screw 21, which is driven by the lifting plate 23 to adjust the height of the fixed mounting frame 1. When the motor 22 is started, the lead screw 21 is driven to rotate. The rotation of the lead screw 21 drives the lifting frame 3 and the scraper plate mounting seat 6 to adjust the height of the lifting frame 3 and the scraper plate mounting seat 6 through the lead screw slide and the lifting plate 23. The lifting frame 3 and the scraper plate mounting seat 6 move up and down by sliding the limit slider on the guide rod 13 in the slide groove 12 on the front and rear sides of the fixed mounting frame 1.

[0026] Specifically, the feed end of the feed pump 8 is connected to the mixing cylinder 7 via a pipeline.

[0027] In addition, this device is fixedly installed on the slipform paver by a fixed mounting bracket 1, and the fixed mounting bracket 1 is equipped with a power supply for the motor 22 and the material pump 8.

[0028] The working principle and usage process of this utility model are as follows: When using this utility model, the workers perform surface finishing and roughening on half or the entire road surface according to the construction road surface. The starting motor 22 drives the lead screw 21 to rotate. The rotation of the lead screw 21 drives the lifting frame 3 and the scraper plate mounting seat 6 to adjust their height through the lead screw slide and the lifting plate 23. The guide rod 13 in the sliding groove 12 on the front and rear sides of the fixed mounting frame 1 is slid by the limit slider, thereby ensuring the stability of the lifting frame 3 and the scraper plate mounting seat 6 during the up and down movement. At the same time, the fixed mounting frame 1 drives the scraper plate 5 and the roughening roller 4 on the same side to move in contact with the ground. The scraper plate 5 finishes half of the road surface, and the roughening roller 4 roughens half of the road surface. The scraper plate 5 and the roughening roller 4 on the other side do not contact the ground and will not come into contact with the other half of the road surface, thus avoiding damage to the road surface. Therefore, even if the surface finishing time on both sides of the road surface is different, the surface finishing and roughening of the road surface that needs to be finished can be carried out smoothly.

[0029] During the surface roughening process, the fixed mounting frame 1 drives the roughening roller 4 to roll on the ground. After the cement is mixed by the mixing drum 7, the slurry is evenly distributed in the distribution box 9 through the conveying pipe 81 by the conveying pump 8, and then evenly sprayed onto the surface of the roughening roller 4 by the nozzle 10. This can work with the cement on the roughening roller 4 to roughen the concrete ground. There is no need for manual repeated feeding of the roughening device, which is convenient to operate, improves the roughening efficiency, and solves the problem of low efficiency of traditional manual roughening devices.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
