Description

Technical Field

[0001] This utility model relates to the field of bridge deck paving technology, and in particular to a mobile automatic bridge deck paving roughening machine. Background Technology

[0002] Roughening is a construction method mainly used in paving operations. Because paving on a smooth surface is not stable and secure enough, there are three methods for roughening: one is to use a cutting machine to make many grooves on the surface; the second is to use a broom dipped in cement slurry to pat the surface, so that the cement slurry seeps in and forms raised dots on the surface; the third is to use high-pressure water roughening, using ultra-high-pressure water jets to directly make many deep grooves on the surface. Automatic roughening machines are usually needed when paving bridge decks.

[0003] In the prior art, when the surface roughening machine is working, the roughening mechanism needs to be replaced in a timely manner to meet different operational needs due to the complex and ever-changing working environment. However, the traditional method of fixing the roughening mechanism with bolts makes the replacement of the mechanism time-consuming, increases the labor intensity of the disassembly and assembly personnel, and is not conducive to improving the working efficiency of the device. Therefore, in order to solve the above problems, this utility model proposes a mobile automatic surface roughening machine for bridge deck paving. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile automatic bridge deck paving texturer. By controlling the magnetism of an electromagnet, the engagement between the limiting block and the groove is adjusted, making the disassembly and assembly of the texturer brush more convenient, reducing the labor intensity of disassembly and assembly personnel, facilitating the replacement of texturer brushes of different specifications and sizes to adapt to different usage needs, improving the applicability of the device, and thus improving the working efficiency of the device.

[0005] This utility model provides the following technical solution: a mobile automatic bridge deck paving roughening machine, comprising a frame, a track fixedly installed in the inner cavity of the frame, magnets with opposite magnetic poles sequentially laid in the track, an electromagnetic slider movably connected to the track, an electric push rod fixedly installed at the bottom of the electromagnetic slider, a lifting seat fixedly installed at the telescopic end of the electric push rod, a sliding groove first opened at the bottom of the lifting seat, a cavity opened in the lifting seat and directly above the sliding groove first, two cavities symmetrically distributed front and back, an electromagnet fixedly installed at the top of the cavity, and a lifting plate movably connected to the cavity. A magnetic block is fixedly installed on the upper part of the lifting plate. Springs are fixedly installed on the top of the cavity and on both sides of the electromagnet. The other end of the spring is fixedly installed on the lifting plate. A limit block is fixedly installed on the bottom of the lifting plate. A rib is engaged in the slide groove. The upper part of the rib has symmetrical grooves that engage with the limit block. A brush is fixedly installed on the bottom of the rib. By controlling the magnetism of the electromagnet, the engagement between the limit block and the groove is adjusted, making it easier to disassemble and assemble the brush, reducing the labor intensity of the disassembly and assembly personnel, and facilitating the replacement of brushes of different sizes to meet different usage needs.

[0006] Preferably, the left and right sides of the frame are respectively fixedly mounted with fixed seats, and servo motors are fixedly mounted in the inner cavity of the fixed seats. There are two servo motors, which are symmetrically distributed front and back. A helical gear one is fixedly sleeved on the output shaft of the servo motor, and a helical gear two is meshed on the outer extension of the helical gear one. The servo motors flexibly drive the transmission device, so that the device can change its form between moving and fixed, thereby enhancing the practicality of the device.

[0007] Preferably, a threaded rod is fixedly installed at the bottom of the helical gear two. The threaded rod is movably sleeved at the bottom of the inner cavity of the fixed seat. The fixed seat has two limiting grooves, which are symmetrically distributed at the front and back of the inner cavity of the fixed seat. The threaded rod is movably sleeved with the limiting groove. The limiting groove can prevent the lifting mechanism from extending too far, so that the moving mechanism is kept on the same horizontal plane.

[0008] Preferably, a second sliding groove is provided at the bottom of the limiting groove, and a lifting rod is movably connected in the limiting groove. The inner cavity of the lifting rod engages with a threaded rod, and a roller is movably connected to the bottom of the lifting rod via a shaft. The roller engages with the second sliding groove, and the threaded rod engages with the inner cavity of the lifting rod, so that when the threaded rod rotates, it drives the lifting rod to slide down in the limiting groove, which facilitates the adjustment of the roller and enhances the flexibility of the device.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By energizing the electromagnetic slider, it slides on the track, thereby driving the textured brush to perform textured work on the bridge deck pavement, which helps to improve the textured accuracy. By energizing the electromagnet, it attracts the magnetic block, which drives the lifting plate to move, disconnecting the limit block from the groove. When the electromagnet is de-energized, the limit block and groove are re-engaged under the elastic potential energy of the spring. This makes the disassembly and assembly of the textured brush more convenient and quick, reducing the labor intensity of the disassembly and assembly personnel. It is also convenient to replace textured brushes of different specifications and sizes to meet different usage needs, which helps to improve the applicability of the device, reduce the time required to replace textured brushes, facilitate later maintenance, and improve the working efficiency of the device.

[0011] 2. The servo motor drives the transmission mechanism, causing the four rollers to move simultaneously from the bottom of the fixed base to support the entire device. The brushing machine can be moved manually, making it more convenient and faster to move. This avoids the need for large equipment such as cranes to assist in moving the device, greatly enhancing its flexibility. When the device reaches the appropriate position, the servo motor rotates in the reverse direction, causing the rollers to re-enter the slide groove two. The fixed base provides support for the device, which helps improve the stability of the device during brushing and prevents positional deviation during brushing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4A mobile automatic bridge deck paving texturer includes a frame 1, a track 2 fixedly installed inside the frame 1, magnets with opposite magnetic poles laid sequentially in the track 2, an electromagnetic slider 3 movably connected to the track 2, an electric push rod 4 fixedly installed at the bottom of the electromagnetic slider 3, a lifting seat 5 fixedly installed at the telescopic end of the electric push rod 4, a groove 6 opened at the bottom of the lifting seat 5, and two cavities 7 symmetrically distributed in front and behind, an electromagnet 8 fixedly installed at the top of the cavity 7, a lifting plate 9 movably connected in the cavity 7, a magnetic block 10 fixedly installed on the upper part of the lifting plate 9, and springs 11 fixedly installed on the top of the cavity 7 on both sides of the electromagnet 8, with the other end of the springs 11 fixedly installed... On the lifting plate 9, a limit block 12 is fixedly installed at the bottom. A rib 13 is engaged in the slide groove 6. The upper part of the rib 13 has symmetrically opened grooves 14, which are engaged with the limit block 12. A textured brush 15 is fixedly installed at the bottom of the rib 13. After the whole device is installed, the lifting seat 5 is lowered by the telescopic end of the electric push rod 4, so that the textured brush 15 under the lifting seat 5 contacts the bridge surface pavement. At this time, the electromagnetic slider 3 is energized. Since magnets with opposite magnetic poles are laid in the track 2 in sequence, the electromagnetic slider 3 is energized to generate a magnetic force that repels the magnets on the track 2, thereby pushing the electromagnetic slider 3 to move. When the electromagnetic slider 3 moves to the track 2 with the next opposite magnetic pole, the electromagnetic slider 3 is energized in the opposite direction, so that the electromagnetic slider 3 moves. Block 3 and track 2 maintain a repulsive magnetic force, enabling the continuous movement of electromagnetic slider 3. When electromagnetic slider 3 needs to stop, the direction of the current on electromagnetic slider 3 is not changed, causing it to attract the magnets laid on track 2, thereby fixing electromagnetic slider 3. By sliding electromagnetic slider 3 on track 2, it drives the textured brush 15 to perform textured work on the bridge surface pavement. Electromagnetic sliding improves the accuracy of textured work. When textured brush 15 needs to be replaced, electromagnet 8 is energized to generate magnetism, attracting the magnetic block 10 below. This causes the magnetic block 10 to move the lifting plate 9 upward, and spring 11 is compressed to generate elastic potential energy. At this time, the engagement between limit block 12 and groove 14 is disengaged, and then the rib 13... The brush 15 can be removed from under the lifting seat 5 by sliding it in the slide groove 6. Align the upper rib 13 of the new brush 15 with the slide groove 6. At this time, the electromagnet 8 is de-energized. Under the action of the elastic potential energy of the spring 11, the lifting plate 9 drives the limiting block 12 to move downward, so that the limiting block 12 and the groove 14 are re-engaged, thereby fixing the brush 15. Compared with the traditional method of fixing with bolts, the disassembly and assembly of the brush 15 is more convenient and quick, reducing the labor intensity of the disassembly and assembly personnel. It is easy to replace brushes 15 of different sizes to meet different usage needs, which helps to improve the applicability of the device, reduce the time required to replace the brush 15, facilitate later maintenance, and improve the working efficiency of the device.

[0019] The frame 1 has two fixed bases 16 fixedly installed on its left and right sides. Two servo motors 17 are fixedly installed inside the cavity of each fixed base 16, symmetrically distributed front and back. A helical gear 18 is fixedly sleeved on the output shaft of each servo motor 17. A helical gear 19 meshes with the outer edge of the helical gear 18. A threaded rod 20 is fixedly installed at the bottom of the helical gear 19, movably sleeved at the bottom of the cavity of the fixed base 16. Two limit grooves 21 are provided in the fixed base 16, symmetrically distributed front and back directly below the cavity of the fixed base 16. The threaded rod 20 is movably sleeved with the limit groove 21. A sliding groove 22 is provided at the bottom of the limit groove 21, and a lifting rod 23 is movably connected to the limit groove 21. The inner cavity of the lifting rod 23 meshes with the threaded rod 20. A roller 24 is movably connected to the bottom of the lifting rod 23 via a shaft. The roller 24 engages with the sliding groove 22. The servo motors 17 drive the helical gear 18. 8. During the rotation of helical gear 18, the engagement of helical gear 29 with helical gear 20 drives the threaded rod 20 to rotate. Since the threaded rod 20 engages with the inner cavity of the lifting rod 23, the rotation of the threaded rod 20 causes the lifting rod 23 to slide and descend in the limiting groove 21. The lifting rod 23 drives the roller 24 at its bottom to move out of the slide groove 22. The four rollers 24 move out from the bottom of the fixed seat 16 at the same time to support the whole device. The brushing machine can be moved by pushing it manually, making the movement of the brushing machine more convenient and faster, avoiding the need for large equipment such as cranes to assist in the movement of the device, and greatly enhancing the flexibility of the device. When the device reaches the appropriate position, the servo motor 17 rotates in the opposite direction, and the above operation is reversed to make the rollers 24 re-enter the slide groove 22. The fixed seat 16 provides support for the device, which helps to improve the stability of the device during brushing and avoids positional deviation during brushing.

[0020] Working principle: The servo motor 17 drives the helical gear 18 to rotate. During the rotation of the helical gear 18, it meshes with the helical gear 19, driving the threaded rod 20 to rotate. Since the threaded rod 20 meshes with the inner cavity of the lifting rod 23, the rotation of the threaded rod 20 causes the lifting rod 23 to slide and descend in the limiting groove 21. The lifting rod 23 drives the roller 24 at its bottom to move out of the sliding groove 22. The four rollers 24 move out from the bottom of the fixed base 16 at the same time to support the entire device. The device can be moved by manually pushing the roughening machine. When the device reaches the appropriate position... The servo motor 17 is rotated in the reverse direction, and the above operation is performed in reverse to make the roller 24 re-enter the slide groove 22. The fixed seat 16 provides support for the device. After the entire device is set up, the lifting seat 5 is lowered by the telescopic end of the electric push rod 4, so that the textured brush 15 under the lifting seat 5 contacts the bridge surface pavement. At this time, the electromagnetic slider 3 is energized. Since magnets with opposite magnetic poles are laid in the track 2 in sequence, the electromagnetic slider 3 generates a magnetic force that repels the magnets on the track 2 after being energized, thereby pushing the electromagnetic slider 3 to move. When the electromagnetic slider 3 moves to the next opposite... When the electromagnetic slider 3 is at track 2, reverse energizing is applied to the electromagnetic slider 3, maintaining a repulsive magnetic force between the electromagnetic slider 3 and track 2, thus enabling continuous movement of the electromagnetic slider 3. When the electromagnetic slider 3 needs to stop, the direction of the current on the electromagnetic slider 3 is not changed, causing it to attract the magnets laid on track 2, thereby fixing the electromagnetic slider 3. The sliding of the electromagnetic slider 3 on track 2 drives the textured brush 15 to perform textured work on the bridge deck pavement. When the textured brush 15 needs to be replaced, the electromagnet 8 is energized to generate magnetism, which then affects the area below... The magnetic block 10 attracts the magnetic block, causing the magnetic block 10 to drive the lifting plate 9 to move upward. The spring 11 is compressed to generate elastic potential energy. At this time, the engagement between the limiting block 12 and the groove 14 is broken. Then, the brush 15 can be removed from below the lifting seat 5 by sliding the rib 13 in the slide groove 6. The rib 13 on the upper part of the new brush 15 is aligned with the slide groove 6. At this time, the electromagnet 8 is de-energized. Under the action of the elastic potential energy of the spring 11, the lifting plate 9 drives the limiting block 12 to move downward, so that the limiting block 12 and the groove 14 are re-engaged, thereby fixing the brush 15.
