Description

Technical Field

[0001] This utility model relates to the field of road joint filling technology, and in particular to a road joint filling and maintenance device for municipal engineering. Background Technology

[0002] During road use, various cracks and joints will appear due to factors such as vehicle load and natural environment. If these cracks and joints are not filled and maintained in a timely manner, rainwater and snowmelt will seep into the base layer and soil layer, damaging the road structure and causing pavement damage. Therefore, road crack filling and maintenance is an important measure to maintain road smoothness and extend road service life, and it is an important part of municipal engineering.

[0003] A municipal engineering road maintenance device, application number CN202221555557.8, includes a filling rod for filling road cracks. The bottom of the filling rod is equipped with a scraping component for scraping and backfilling excess filler from the road surface. The scraping component is mounted on the bottom of the filling rod via a mounting base. A delivery pipe for conveying filler is installed inside the filling rod. This device can scrape away excess filler that overflows during the filling process and backfill it into the cracks. This avoids the unevenness caused by excessive filler overflowing and drying, thus improving the quality of the filling. Furthermore, by backfilling the excess filler into the cracks, waste due to overflow is avoided.

[0004] Existing patented road crack filling and maintenance devices improve upon the filling rod at the road crack filling point, where a single set of V-shaped scrapers scrapes excess filler back into the crack. However, this scraper structure is relatively simple and does not effectively guide the filler away from the crack or prevent overflow after the filler is squeezed out. Therefore, we propose a road crack filling and maintenance device for municipal engineering. Utility Model Content

[0005] The main objective of this invention is to provide a road joint filling and maintenance device for municipal engineering. It incorporates a bottom pipe and a guide mechanism at the filling rod used in existing road joint filling and maintenance systems. The guide mechanism at the bottom of the filling rod precisely guides the filler into the road joints. The combined design of the diamond frame and the U-shaped rubber strip ensures that the filler fully fills the road joints while effectively preventing excessive overflow, thus improving filling efficiency. Furthermore, the semi-circular sliding strip design on the lower surface of the guide mechanism's limiting plate allows the U-shaped rubber strip to slide smoothly on the road surface, adapting to different road conditions and joint shapes, ensuring consistent and uniform filling results. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A road crack caulking and maintenance device for municipal engineering includes a filling rod and a base pipe. The base pipe is fixed to the bottom of the filling rod. The device also includes a guide mechanism, which comprises a sleeve, side plates, L-shaped hooks, pins, a U-shaped metal plate, a U-shaped rubber strip, a diamond frame, a limiting plate, a semi-circular slide bar, and a semi-circular guide cover. The sleeve is fitted at the bottom of the filling rod, and the sleeve body is bolted to the outside of the filling rod. Side plates are symmetrically fixed on both sides of the sleeve, and the outer surface of the side plates has L-shaped openings for mounting the L-shaped hooks. The L-shaped hook block is inserted between the L-shaped hook block and the side plate. The L-shaped hook block is integrally formed on the outside of the U-shaped metal plate. A U-shaped rubber strip is bonded to the lower surface of the U-shaped metal plate. The arc-shaped part of the U-shaped rubber strip is recessed to form a notch for embedding a diamond frame. The diamond frame is bonded and fixed to the cavity of the notch. A limiting plate is integrally formed below the inclined part of the U-shaped rubber strip. A semi-circular guide cover is welded to the outside of the bottom tube. A D-shaped plate is fixed to the outer cover of the semi-circular guide cover away from the bottom tube.

[0008] Furthermore, a cavity for accommodating filler is reserved between the corner frame at one end of the rhombus frame and the inner arc surface of the U-shaped rubber strip, and an outer cavity for accommodating filler is reserved between the corner frame at the other end of the rhombus frame and the outer arc surface of the U-shaped rubber strip.

[0009] By adopting the above technical solution, the filler extruded from the bottom pipe can fall into the inner cavity between the diamond frame and the U-shaped rubber strip. The filler can enter the road gap at the inner cavity, while the filler overflowing from the road gap can be restricted by the diamond frame. The excess filler is continuously scraped and left above the road gap at the outer cavity of the U-shaped rubber strip and the diamond frame for coating.

[0010] Furthermore, a pin hole is provided between the L-shaped hook block and the side plate, and a pin is inserted between the L-shaped hook block and the pin hole of the side plate, and the pin rod of the pin has a rib ring protruding outward.

[0011] By adopting the above technical solution, the pin holes of the L-shaped hook block and the side plate can be connected by inserting pins, ensuring that the L-shaped hook block is not easy to fall off from the side plate.

[0012] Furthermore, an installation hole is provided between the tube body of the sleeve and the bottom rod head of the filling rod, and a bolt is screwed between the installation hole of the sleeve and the filling rod;

[0013] By adopting the above technical solution, after screwing bolts between the mounting holes of the sleeve and the filler rod, the sleeve can be firmly locked at the filler rod.

[0014] Furthermore, a semi-circular sliding strip is integrally formed on the lower surface of the limiting plate;

[0015] By adopting the above technical solution, the limiter can slide smoothly on the road surface with a semi-circular slider, ensuring smooth movement of the limiter on the ground.

[0016] Furthermore, the dimensions of the L-shaped hook block are the same as the dimensions of the L-shaped groove;

[0017] By adopting the above technical solution, the L-shaped hook block can be smoothly inserted into the L-shaped fixed groove for acceptance and mounting.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model sets a bottom tube and a guide mechanism at the filling rod used for existing road joint filling and maintenance. The guide mechanism at the bottom of the filling rod can accurately guide the filler into the road joint. The cooperative design of the diamond frame and the U-shaped rubber strip can not only fully fill the road joint, but also effectively prevent the filler from overflowing, thus improving the filling efficiency.

[0020] Furthermore, the semi-circular sliding strip design on the lower surface of the guide limiter plate of the guide limiter mechanism allows the U-shaped rubber strip to slide smoothly on the road surface, adapting to different road conditions and gap shapes, ensuring the consistency and uniformity of the filling effect. The connection between the various components of the guide limiter mechanism is also easy to disassemble and replace. In the long-term use, if any damaged or worn parts are encountered, they can be easily repaired or replaced. Attached Figure Description

[0026] like Figure 1-3 As shown, a road joint caulking and maintenance device for municipal engineering includes a filling rod 1 and a bottom pipe 2. The bottom pipe 2 is fixed to the bottom of the filling rod 1. The device also includes a guide mechanism 3, which comprises a sleeve 4, side plates 5, L-shaped hooks 7, pins 9, a U-shaped metal plate 10, a U-shaped rubber strip 11, a diamond frame 13, a limiting plate 14, a semi-circular sliding strip 15, and a semi-circular guide cover 16. The sleeve 4 is fitted at the bottom of the filling rod 1, and the sleeve 4 is bolted to the outside of the filling rod 1. Side plates 5 are symmetrically fixed on both sides of the sleeve 4, and L-shaped hooks 7 are provided on the outer surface of the side plates 5 for mounting the L-shaped hooks 7. The L-shaped hook 7 and the side plate 5 are connected by a pin 9. The L-shaped hook 7 is integrally formed on the outside of the U-shaped metal plate 10. A U-shaped rubber strip 11 is bonded to the lower surface of the U-shaped metal plate 10. The arc-shaped strip of the U-shaped rubber strip 11 is recessed to form a notch 12 for embedding a diamond frame 13. The diamond frame 13 is bonded and fixed to the cavity of the notch 12. A limiting plate 14 is integrally formed below the inclined strip of the U-shaped rubber strip 11. A semi-circular guide cover 16 is welded to the outside of the pipe opening of the bottom tube 2. A D-shaped plate 17 is fixed to the outer cover opening of the semi-circular guide cover 16 away from the bottom tube 2.

[0027] Wherein, a cavity for accommodating filler is reserved between the corner frame at one end of the rhombus frame 13 and the inner arc surface of the U-shaped rubber strip 11, and an outer cavity for accommodating filler is reserved between the corner frame at the other end of the rhombus frame 13 and the outer arc surface of the U-shaped rubber strip 11.

[0028] By adopting the above technical solution, the filler extruded from the bottom tube 2 can fall into the inner cavity between the diamond frame 13 and the U-shaped rubber strip 11. The filler can enter the road gap at the inner cavity, while the filler overflowing from the road gap can be restricted by the diamond frame 13. The excess filler is continuously scraped and left above the road gap at the outer cavity of the U-shaped rubber strip 11 and the diamond frame 13 for coating.

[0029] Wherein, a pin hole 8 is provided between the L-shaped hook block 7 and the side plate 5, and a pin 9 is inserted between the L-shaped hook block 7 and the pin hole 8 of the side plate 5, and the pin 9 has a rib ring protruding from the pin rod.

[0030] By adopting the above technical solution, the L-shaped hook block 7 and the pin hole 8 of the side plate 5 can be connected by inserting a pin 9, ensuring that the L-shaped hook block 7 is not easy to fall off from the side plate 5.

[0031] The sleeve 4 has an installation hole between its body and the bottom head of the filling rod 1, and a bolt is screwed between the installation hole of the sleeve 4 and the filling rod 1.

[0032] By adopting the above technical solution, after the bolts are screwed between the mounting holes of the sleeve 4 and the filling rod 1, the sleeve 4 can be firmly locked at the filling rod 1.

[0033] The lower surface of the limiting plate 14 is integrally formed with a semi-circular sliding strip 15;

[0034] By adopting the above technical solution, the limiter 14 can slide smoothly on the road surface with the semi-circular slide bar 15, ensuring that the limiter 14 moves smoothly on the ground.

[0035] The dimensions of the L-shaped hook block 7 are the same as the dimensions of the L-shaped groove 6.

[0036] By adopting the above technical solution, the L-shaped hook block 7 can be smoothly inserted into the L-shaped fixed groove 6 for reception and mounting.

[0037] It should be noted that this utility model is a road joint filling and maintenance device for municipal engineering. A bottom pipe 2 and a guide mechanism 3 are installed at the existing road joint filling rod 1. The sleeve 4 of the guide mechanism 3 can be fitted from the bottom pipe 2 onto the bottom end of the filling rod 1. Then, bolts are screwed into the sleeve 4 and the mounting holes of the filling rod 1 to install the sleeve 4. At this time, the U-shaped metal plate 10 can be pried open in opposite directions, and the L-shaped hook block 7 is inserted into the L-shaped groove 6. Then, a pin 9 is inserted between the L-shaped hook block 7 and the pin hole 8 of the side plate 5 for pin connection. The U-shaped metal plate 10 is then released, and it elastically returns to its original shape. The U-shaped rubber strip 11 below the U-shaped metal plate 10, with a notch 12, can be used to attach a diamond frame 13. When the pipe of the filling rod 1 is connected to the asphalt pump of the crack filling machine for municipal engineering road joint filling and maintenance... During operation, the worker can hold the filling rod 1, and then press the filling rod 1 against the ground with the U-shaped rubber strip 11 below the U-shaped metal plate 10. Then, the limiting plate 14 at the U-shaped rubber strip 11 slides smoothly on the ground. When the asphalt-based filler is squeezed out from the filling rod 1 and the bottom pipe 2, the filler is restricted by the semi-circular guide cover 16 and the D-shaped plate 17 and falls into the inner cavity between the diamond frame 13 and the U-shaped rubber strip 11. The filler can enter the road gap at the inner cavity, and the filler overflowing from the road gap can be restricted by the diamond frame 13. The excess filler is continuously scraped and left above the road gap at the outer cavity of the U-shaped rubber strip 11 and the diamond frame 13 for coating, avoiding excessive overflow of filler at the road gap and ensuring that the filler can cover the road gap well for filling and maintenance.
