[0034] like Figures 1 to 6 The epoxy resin automatic coating device for waterproof bonding layer of steel bridge deck shown includes: storage bin 1, traveling component 3 and scraper 21. Storage bin 1 is equipped with a discharge switch 5 at the discharge port; traveling component 3 is used to support and drive storage bin 1 to move; scraper 21 is set at the rear end of the discharge port along the traveling direction of traveling component 3, and is used to scrape the epoxy resin flowing onto the steel bridge deck.
[0035] The walking component 3 includes two walking wheels 31 symmetrically arranged on both sides of the storage bin 1, at least one power wheel 32 for traction of the storage bin 1, and a drive component 33 for driving the power wheel 32 to rotate to achieve active traction.
[0036] During implementation, according to the coating thickness required by the construction drawings, the scraper 21 is adjusted to a suitable coating height; the adhesive is manually poured into the storage bin 1, the drive component 33 is started, the drive component 33 drives the power wheel 32 to rotate, and cooperates with the two walking wheels 31 to make the storage bin 1 move on the steel bridge surface. The flowing adhesive is evenly spread on the steel bridge surface under the action of the scraper 21 to form a smooth epoxy resin adhesive layer.
[0037] This invention achieves automatic coating through scraper 21 and walking component 3. Compared with manual coating, it avoids problems such as uneven thickness and uneven surface caused by human factors. Moreover, when facing the construction of large-area steel bridge decks, the automatic coating device has strong continuous operation capability, without the need for frequent stops and adjustments, reducing the number of interruptions, and can quickly complete the coating of epoxy resin adhesive layer, greatly shortening the construction cycle and further improving the overall construction efficiency. Furthermore, the uniform adhesive layer formed by scraper 21 can better withstand vehicle loads, prevent local stress concentration, and thus extend the service life of the steel bridge.
[0038] The automatic coating device's travel system and scraper 21 can be adjusted and adapted to different bridge deck conditions. Whether it's a straight section, a curved section, or a bridge deck with different widths and slopes, it can smoothly complete the coating operation, ensuring consistent construction quality and efficiency. Furthermore, on different parts of the steel bridge deck or on different types of steel bridges, the coating parameters can be adjusted according to design requirements to precisely control the amount of epoxy resin adhesive used, reducing excess adhesive overflow and dripping, thereby reducing pollution to the surrounding environment and achieving optimal construction results.
[0039] Automatic coating devices are relatively simple to operate, and can generally be mastered by operators after a short period of training. Operators set parameters such as coating speed and thickness through the control panel, and the equipment can automatically perform coating operations according to the set requirements, reducing reliance on manual skills and minimizing construction errors caused by human factors.
[0040] In a preferred embodiment of this invention, the discharge port of the storage silo 1 is provided with a distribution plate 4, and a plurality of discharge holes 4a are evenly arranged on the distribution plate 4. The discharge holes 4a are small circular holes with a radius of 1cm. The even arrangement of the circular discharge holes 4a can avoid uneven flow of epoxy resin, reduce the workload of subsequent leveling processes, and thus ensure the uniformity of the coating. In addition, according to the thickness requirements of the epoxy resin layer, the flow rate of epoxy resin can be controlled by sealing some of the discharge holes 4a.
[0041] In a preferred embodiment, the discharge switch 5 includes a rotating shaft 51, a tilting plate 52, and a drive linkage assembly 53; the rotating shaft 51 is connected to the tilting plate 52, and the drive linkage assembly 53 is used to drive the rotating shaft 51 to rotate so as to tilt the tilting plate 52.
[0042] When the tilting plate 52 is parallel to the distribution plate 4, the outlet of the storage hopper 1 is closed. When the tilting plate 52 is tilted at a certain angle by rotating the rotating shaft 51, the outlet is open. By controlling the rotation of the rotating shaft 51 through the drive linkage assembly 53, the tilting plate 52 can be precisely tilted, thereby precisely controlling the opening and closing degree of the outlet and further controlling the flow rate of epoxy resin. This design allows for continuous adjustment from completely closed to completely open, meeting different construction needs.
[0043] As a preferred embodiment of the above scheme, the flip plate 52 is positioned above the distribution plate 4. The flip plate 52 can serve as a pre-dispensing device, directly controlling the flow rate of the epoxy resin flowing onto the distribution plate 4 to ensure the uniformity of the coating.
[0044] As a preferred embodiment of the above solution, the drive linkage assembly 53 includes a first link 531 connected to one end of the rotating shaft 51, a second link 532 hinged to the first link 531, and a manual grip 533 for driving the second link 532 to swing the first link 531.
[0045] The second connecting rod 532 is directly driven by the manual lever 533, which in turn causes the first connecting rod 531 to swing, ultimately achieving the rotation of the rotating shaft 51. This design eliminates the need for complex electrical or hydraulic systems, is simple and intuitive to operate, and is suitable for quickly adjusting the state of the discharge switch 5 on the construction site.
[0046] In this utility model, the drive assembly 33 includes a drive motor 331, a drive pulley 332, a driven pulley 333, and a transmission belt 334; the drive pulley 332 is mounted on the drive shaft of the drive motor 331, the driven pulley 333 is connected to the power wheel 32 via a connecting shaft, and the transmission belt 334 is wrapped around the drive pulley 332 and the driven pulley 333.
[0047] Preferably, the drive assembly 33 further includes a power switch and multiple adjustment buttons. The power switch is used to enable one-button start and stop of the drive assembly 33; operation is simple and quick, allowing operators to quickly control the operating status of the equipment. The multiple adjustment buttons are used to control the speed and direction of rotation of the drive motor 331, so as to further control the forward, backward, and movement speed of the power wheel 32.
[0048] The motor drive is more stable and reliable than manual or hydraulic operation, reducing safety hazards caused by improper operation or equipment failure. The one-button start / stop and adjustment buttons make the operation more intuitive, and operators can become proficient in using it after simple training.
[0049] In the preferred embodiment of this utility model, the traveling wheel 31 is a steel gear, and its outer cylindrical surface is provided with a plurality of sharp teeth 31a along the circumferential direction. It is used to balance the equipment so that it can travel on the surface of the steel bridge deck, and can prevent the wheel from adhering to and damaging the adhesive layer on the coated steel bridge deck surface during the travel process.
[0050] As a preferred embodiment of this utility model, the scraping device also includes a manual braking system 6 for decelerating the power wheel 32 during movement.
[0051] The manual braking system 6 allows operators to flexibly control the deceleration force and speed according to actual needs, adapting to different construction scenarios. By adding the manual braking system 6, the safety, operational flexibility, and reliability of the equipment can be significantly improved.
[0052] In a preferred embodiment of this invention, the coating device further includes a diesel generator, and a support for mounting the diesel generator is provided above the storage silo 1. The diesel generator provides power to the drive assembly 33.
