Description

Technical Field

[0001] The present invention relates to the technical field of sleeper surface treatment, and specifically to a sleeper surface roughness treatment device and a treatment method thereof. Background Art

[0002] During the use of double-block ballastless tracks, we found that cracks extending outward along the 45° direction are likely to form at the four corners of the sleepers in the cast-in-place integral ballast bed, and this phenomenon is very common. If not treated or not treated well, microcracks of varying degrees will appear around the sleepers. With the erosion of rainwater, the microcracks will gradually form through cracks. Therefore, rough treatment of the concrete surface can effectively improve the bonding force between new and old concretes and reduce the generation of microscopic gaps.

[0003] Currently, there are two relatively common treatments. One is to paste chiseling belts inside the mold. The main problems of this process are: chiseling belts must be pasted before each set of molds is produced, which seriously affects production efficiency. The roughness of the formed rough surface is very low, and it is only the combination of the surface mortar layer with low adhesion. The thickness of the chiseling belt is relatively large, affecting the type and size of the sleepers. The other is to spray a retarder inside the mold cavity. After the finished product is demolded, a high-pressure water gun is used to wash away the surface mortar layer. The main problems of this process are: it is difficult to ensure that the retarder does not drip onto the bottom surface of the mold during the spraying process, resulting in the formation of retardation on the load-bearing surface as well. The load-bearing surface of the finished sleeper becomes a non-smooth surface, which does not meet the specification requirements. After each finished product is demolded, the side of the mold needs to be re-sprayed with the retarder, and the actual operation process is complicated, and the retarder has a certain impact on the surface strength of the concrete. During the high-pressure water gun washing process, a uniform rough surface cannot be formed, and the depth of the rough surface is not easy to guarantee. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a sleeper surface roughness treatment device and a treatment method thereof. The depth of the rough surface can be adjusted by controlling the water pressure, efficiently and accurately controlling the depth of the rough surface treatment, so that an ideal bonding effect can be achieved during the secondary pouring, and the surface treatment efficiency can be improved.

[0005] To achieve the above object, the present invention provides the following technical solution: A sleeper surface roughness treatment device includes an installation area. On one side of the upper end of the installation area, a traction component is installed, and on the other side of the upper end of the installation area, a sleeper conveying component is installed. On the upper end of the installation area and outside the sleeper conveying component, a water spraying treatment component is installed. The water spraying treatment component includes two installation boxes symmetrically installed at the top of the installation area. A protective cover is installed between the two installation boxes. Inside the installation box, two hydraulic rotary heads are installed. One end of the hydraulic rotary head is provided with a rotary disk, and a plurality of nozzles are installed at one end of the rotary disk.

[0006] Preferably, the traction component includes a mounting base plate installed on one side of the upper end of the installation area. On one side of the upper end of the mounting base plate, a first mounting seat is installed. On the other side of the upper end of the mounting base plate, a transmission seat is installed. A first rotating rod is rotatably installed between the transmission seat and the first mounting seat. On one side of the outer wall of the first rotating rod, a winding and unwinding turntable is installed. On one side of the transmission seat, a traction motor is installed. A winding and unwinding pulling rope is wound around the inner side of the winding and unwinding turntable. On the other side of the upper end of the installation area, a second mounting seat is installed. At the upper inner side of the second mounting seat, a second rotating rod is installed. A fixed pulley is rotatably installed in the middle of the second rotating rod.

[0007] Preferably, the sleeper conveying component includes two sliding tracks installed at the top of the installation area. Above the two sliding tracks, a conveying trolley is slidably arranged. At the bottom of the conveying trolley, rolling rollers used in cooperation with the sliding tracks are installed. Above the conveying trolley, a sleeper body is placed. The upper end cover of the sleeper body contains a shielding cover plate. At the two edges of the top end of the conveying trolley, side baffles are installed. At the two edges of the sliding direction at the bottom end of the conveying trolley, pulling rope fixing seats are installed.

[0008] Preferably, there is a surplus when the winding and unwinding pulling rope is wound around the winding and unwinding turntable. One end of the winding and unwinding pulling rope is connected to one of the pulling rope fixing seats through the fixed pulley for direction change. The other end of the winding and unwinding pulling rope is connected to the other pulling rope fixing seat. Thus, by controlling the forward and reverse rotation of the traction motor, the moving direction of the conveying trolley can be controlled.

[0009] Preferably, the shielding cover plate is closely attached to the upper end of the sleeper body. The shielding cover plate forms a shielding area for the upper end of the sleeper body. The side baffles are higher than the lower edge of the sleeper body.

[0010] Preferably, the sleeper conveying component includes a conveying frame installed at a certain place. Above the conveying frame, rotatable conveying rollers are linearly arranged. Above the conveying rollers, a sleeper body is placed.

[0011] A method for treating the surface roughness of a sleeper: includes the following treatment steps: S1. Lift each sleeper body to the sleeper conveying component one by one, with one side of the sleeper body perpendicular to the water spraying direction of the nozzle. S2. And by controlling the rotation of the sleeper conveying component, the sleeper body is tractionally conveyed. S3. Start the water spraying treatment component. Drive the rotating disk to rotate through the hydraulic rotating head, so that a rotating and spraying high-pressure water jet is generated at the nozzle. The two-stage water jet treatment of the sleeper body is carried out by two groups of nozzles to obtain a sleeper body with a surface roughness of 2 - 3 mm. S4. Re-stack the surface-treated sleeper bodies.

[0012] Preferably, the traction speed in S2 is 5 - 10 m / min.

[0013] Preferably, in the first-stage water jet treatment in S3, the rotation speed of the rotating disk is 400 - 500 rpm, the water jet pressure of the nozzle is 120 - 160 MPa, and the roughness after treatment is 1 - 2 mm; In the second-stage water jet treatment, the rotation speed of the rotating disk is 300 - 400 rpm, the water jet pressure of the nozzle is 80 - 120 MPa, and the roughness after treatment is 2 - 3 mm.

[0014] Compared with the prior art, the present invention provides a sleeper surface roughness treatment device and a treatment method thereof, having the following beneficial effects: This design adopts a continuous conveying and treatment method to realize the treatment of the surface roughness of the sleeper body, improving the overall production efficiency.

[0015] The two-stage treatment method, on the one hand, can use a relatively small water jet pressure and rotation speed during the second-stage treatment, which can more accurately control the surface treatment depth of the sleeper body while not causing the shedding of the aggregate in the sleeper body, affecting the structural strength of the sleeper body. Moreover, the sleeper body after two-stage treatment has a higher bonding strength after secondary pouring, solving the problem of different degrees of microcracks easily appearing around the sleeper body.

[0019] Please refer to Figure 1-8 , the present invention provides a technical solution for a sleeper surface roughness treatment device and its treatment method: Embodiment 1, a sleeper surface roughness treatment device, including an installation area 1, a towing component 3 is installed on one side of the upper end of the installation area 1, a sleeper conveying component 4 is installed on the other side of the upper end of the installation area 1, and a water spraying treatment component 2 is installed on the upper end of the installation area 1 and outside the sleeper conveying component 4; The water spraying treatment component 2 includes two installation box bodies 21 symmetrically installed on the top of the installation area 1, a protective cover 22 is installed between the two installation box bodies 21, two hydraulic rotating heads 23 are installed inside the installation box body 21, a rotating disk 24 is arranged at one end of the hydraulic rotating head 23, and a plurality of nozzles 25 are installed at one end of the rotating disk 24, and a high-pressure pump is used to supply water to the nozzles 25; The towing component 3 includes an installation bottom plate 31 installed on one side of the upper end of the installation area 1, a first installation seat 33 is installed on one side of the upper end of the installation bottom plate 31, a transmission seat 32 is installed on the other side of the upper end of the installation bottom plate 31, a first rotating rod 34 is rotatably installed between the transmission seat 32 and the first installation seat 33, a retracting and releasing turntable 35 is installed on one side of the outer wall of the first rotating rod 34, a towing motor 36 is installed on one side of the transmission seat 32, a retracting and releasing pulling rope 37 is wound around the inside of the retracting and releasing turntable 35, a second installation seat 38 is installed on the other side of the upper end of the installation area 1, a second rotating rod 39 is installed on the upper inner side of the second installation seat 38, and a fixed pulley 391 is rotatably installed in the middle of the second rotating rod 39; The sleeper conveying component 4 includes two sliding tracks 46 installed at the top of the installation area 1. A conveying trolley 41 is slidably arranged above the two sliding tracks 46. Rolling rollers 42 cooperating with the sliding tracks 46 are installed at the bottom of the conveying trolley 41. A sleeper body 44 is placed above the conveying trolley 41. A shielding cover plate 45 is provided on the upper end of the sleeper body 44. Side baffles 43 are installed at both edges of the top end of the conveying trolley 41. Rope fixing seats 47 are installed at both edges of the sliding direction of the bottom end of the conveying trolley 41. It should be noted that the function of the sleeper conveying component 4 is to convey the sleeper body 44. The sleeper conveying component 4 is not the only limitation of the conveying method, as long as the continuous conveying of the sleeper body 44 can be achieved. The function of the shielding cover plate 45 is to shield the upper end of the sleeper body 44 to prevent the falling of materials above and affect the overall aesthetics. The retractable pull rope 37 has a surplus when wound around the retractable turntable 35. One end of the retractable pull rope 37 is connected to one of the rope fixing seats 47 through a reversing connection of a fixed pulley 391, and the other end of the retractable pull rope 37 is connected to the other rope fixing seat 47. Thus, by controlling the forward and reverse rotation of the traction motor 36, the moving direction of the conveying trolley 41 can be controlled. The shielding cover plate 45 is closely attached to the upper end of the sleeper body 44. The shielding cover plate 45 forms a shielding area for the upper end of the sleeper body 44 to ensure that it will not be impacted by water flow from above, making the upper part of the sleeper body 44 more complete and more aesthetic. The side baffles 43 are higher than the lower edge of the sleeper body 44 to prevent the lower corners from being washed away.

[0020] In the second embodiment, the sleeper conveying component 4 includes a conveying frame 48 installed at 1. Rotatable conveying rollers 49 are linearly arranged above the conveying frame 48. The sleeper body 44 is placed above the conveying rollers 49.

[0021] In the third embodiment, a method for treating the surface roughness of a sleeper includes the following treatment steps: S1. Lift the sleeper body 44 to the sleeper conveying component 4 one by one, with one side of the sleeper body 44 perpendicular to the water spraying direction of the spray head 25. S2. Control the rotation of the sleeper conveying component 4 to traction-convey the sleeper body 44. S3. Start the water spraying treatment component 2. Drive the rotating disk 24 to rotate through the hydraulic rotating head 23, so that a rotating and spraying high-pressure water jet is generated at the spray head 25. The two-stage water jet treatment of the sleeper body 44 is carried out by two groups of spray heads 25 to obtain a sleeper body 44 with a surface roughness of 2 - 3 mm. S4. Re-stack the surface-treated sleeper body 44. The traction speed in S2 is 5 - 10 m / min, which can ensure that while the water jet treats the surface of the sleeper body 44, it will not cause the treatment depth to be too large and cause the shedding of aggregates.

[0022] In the first stage of water jet treatment in S3, the rotational speed of the rotating disk 24 is 400 - 500 rpm, the water jet pressure of the nozzle 25 is 120 - 160 MPa, and the surface roughness after treatment is 1 - 2 mm. In the second stage of water jet treatment, the rotational speed of the rotating disk 24 is 300 - 400 rpm, the water jet pressure of the nozzle 25 is 80 - 120 MPa, and the surface roughness after treatment is 2 - 3 mm.

[0023] Bond strength test process: Test preparation: A total of 3 groups of 150*150*150 mm test blocks were prepared. The first group was treated with a rough surface using the treatment equipment of the present invention and only underwent the first stage of water jet treatment with a treatment depth of 1 - 2 mm. The second group was not treated. The third group was treated with a rough surface using the treatment equipment of the present invention and underwent two - stage water jet treatment with a treatment depth of 2 - 3 mm. After secondary pouring respectively, flexural strength test blocks of 600*150*150 mm were formed, and the bond strength test was carried out on the test blocks with an age of 7 days. The test fracture surfaces were all the new - old concrete bonding surfaces, and the test results are as follows:

[0024] It can be seen from the above test data that after the surface of the sleeper body 44 is treated by the two - stage water jet of the present invention, the bond strength after the secondary pouring of the sleeper is greatly improved, thus solving the problem that different degrees of micro - cracks are likely to appear around the sleeper body 44.

[0025] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
