Description

Technical Field

[0001] This utility model relates to the field of railway bridge crack repair technology, and in particular to a surface-plastering device. Background Technology

[0002] Railway bridges are important structures that allow railway lines to cross natural or man-made obstacles. They provide crossing channels for the safe and smooth passage of trains and are an indispensable key part of railway transportation. Railway bridges come in various forms, including beam bridges, arch bridges, suspension bridges, and cable-stayed bridges. They are selected and constructed according to different geographical environments, geological conditions, and crossing requirements. Their structures are complex and must have sufficient strength, rigidity, and stability to withstand the huge loads generated by train travel and various forces from the natural environment, ensuring the smooth flow of railway transportation.

[0003] For repairing cracks in railway bridges, commonly used repair materials include various types of concrete repair agents and polymer mortar. After filling the cracks, these repair materials need to undergo a series of construction operations to ensure a tight bond with the original bridge structure and achieve a good repair effect. Among these, the finishing process is one of the key steps, as it directly affects the smoothness of the repair material surface, its adhesion to the bridge structure, and the overall repair quality. However, existing finishing devices only have simple material storage and application functions. During storage, the material adheres to the inner wall of the storage device, resulting in insufficient mixing, easy sedimentation, and stratification, which in turn affects the repair quality. At the same time, the rolling mechanism in existing finishing devices is usually fixedly connected, which makes it impossible to flexibly adjust the position of the pressure roller according to the actual situation, making it difficult to apply appropriate pressure to cracks of different depths and widths.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1: Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a surface-applying device, including a base plate 1, a storage tank 2 is arranged above the base plate 1, and a stirring component 3 is arranged inside the storage tank 2.

[0024] The base plate 1 serves as the basic support structure for the entire device, providing installation positions for other components and ensuring the stability and mobility of the overall structure of the device. The storage tank 2 is used to store repair materials for repairing cracks in railway bridges. The mixing component 3 can mix the repair materials in the storage tank 2 through its internal structure. At the same time, it can scrape off the material adhering to the inner wall of the storage tank 2 during the mixing process, reducing material waste.

[0025] Two sets of pressure rollers 4 are provided at the bottom of the base plate 1. An adjustment component 5 for adjusting the position of the pressure rollers 4 is provided at the bottom of the base plate 1. A fixing frame 6 is fixed at the top of the base plate 1. Two sets of slide rods 7 are slidably connected to the inner wall of the fixing frame 6. A scraper 8 arranged horizontally is fixed at the bottom end of the slide rod 7.

[0026] The pressure roller 4 is used to roll the repair material applied to the crack, making the material fill the crack more tightly, enhancing the repair effect, and improving the adhesion and smoothness of the repair layer to the bridge structure. The adjustment component 5 can adjust the position of the pressure roller 4 through its internal structure to ensure that the pressure roller 4 can apply appropriate pressure to the repair material. The fixing frame 6 is used to provide installation support for the slide bar 7 and the threaded rod 9. The up and down movement of the slide bar 7 can guide the scraper 8, keeping the scraper 8 stable during the up and down movement. The scraper 8 can scrape the repair material applied to the crack during the movement of the device, making the surface of the repair material smooth and ensuring the surface quality of the bridge after repair.

[0027] The adjustment assembly 5 includes a limiting frame 51 fixed to the inner wall of the base plate 1. A fixing block 52 is fixed to the top of the limiting frame 51. A movable block 53 is slidably connected to the inner wall of the limiting frame 51. The inner wall of the movable block 53 is rotatably connected to the outer side of the pressure roller 4. A screw 54 is rotatably connected to the top of the movable block 53. The outer side of the screw 54 is threadedly connected to the inner wall of the fixing block 52.

[0028] The limiting frame 51 is set to provide a track for the sliding of the movable block 53, restrict the movement direction of the movable block 53, and ensure that it can only slide in a specific direction. The fixed block 52 is fixed to the top of the limiting frame 51 to provide a rotation support point for the screw 54. Since the outer side of the screw 54 is threadedly connected to the inner wall of the fixed block 52, and the inner wall of the movable block 53 is rotatably connected to the outer side of the pressure roller 4, and the movable block 53 slides on the inner wall of the limiting frame 51, rotating the screw 54 will drive the movable block 53 to move up and down in the limiting frame 51, thereby adjusting the position of the pressure roller 4 and ensuring that the pressure roller 4 can apply appropriate pressure to the repair material.

[0029] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the inner wall of the fixing frame 6 is threaded with a threaded rod 9, the bottom end of the threaded rod 9 is rotatably connected to the top of the scraper 8, and a turntable is fixed to the top of the threaded rod 9. A corrugated pipe 10 is sleeved on the outer side of the threaded rod 9.

[0031] By rotating the turntable at the top of the threaded rod 9, the threaded rod 9 can move up and down within the fixed frame 6, thereby driving the scraper 8 to move up and down, thus adjusting the height of the scraper 8. The bellows 10 is sleeved on the outside of the threaded rod 9 to prevent external dust and debris from entering the threaded connection between the threaded rod 9 and the fixed frame 6.

[0032] Specifically, the bottom of the base plate 1 is provided with four sets of moving wheels 11, the top of the base plate 1 is fixed with a push rod 12, the top of the base plate 1 is fixed with a support frame 13, and the outside of the support frame 13 is fixed with a fixing ring 14 for fixing the storage tank 2.

[0033] The movable wheels 11 facilitate the movement of the entire device on the railway bridge, enabling the device to quickly reach the location of the crack that needs repair. The operator can move the device by pushing the push rod 12. The support frame 13 and the fixing ring 14 work together to provide stable support for the storage tank 2, ensuring the stability of the storage tank 2 during the movement and operation of the device.

[0034] Specifically, a sealing cover 15 is rotatably connected to the top of the storage tank 2, and a locking element 16 for locking the sealing cover 15 is provided on the outside of the storage tank 2.

[0035] The sealing cover 15 is used to seal the storage tank 2, preventing external dust and moisture from entering the storage tank 2 during storage and transportation, which would affect the quality of the repair materials. It also prevents material leakage. The locking element 16 is used to lock the sealing cover 15, ensuring that the sealing cover 15 will not be accidentally opened during device movement and operation, thus guaranteeing the airtightness of the storage tank 2. It should be noted that the locking element 16 includes a fixing plate fixed to the outside of the storage tank 2, a T-shaped rod rotating on the inner wall of the fixing plate, and a U-shaped block fixed to the top of the sealing cover 15. The outer side of the T-shaped rod is threaded with a fixing nut. When locking the sealing cover 15, first rotate the T-shaped rod upward so that the outer side of the T-shaped rod rotates into the U-shaped groove of the U-shaped block, and then tighten the fixing bolt to complete the fixing of the sealing cover 15. When it is necessary to open the sealing cover 15, simply loosen the fixing nut and then rotate the T-shaped rod to disengage the T-shaped rod from the U-shaped block to open the sealing cover 15.

[0036] Specifically, the bottom of the storage tank 2 is connected to a vertically arranged discharge pipe 17, and a control valve 18 is installed on the outside of the discharge pipe 17.

[0037] The discharge pipe 17 is used to discharge the repair material in the storage tank 2 to the crack that needs to be repaired. It is the material output channel. The control valve 18 is used to control the opening and closing of the discharge pipe 17. The operator can control the amount of material to be fed through the control valve 18 according to the actual operation needs.

[0038] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] Specifically, the stirring component 3 includes a transmission rod 31 disposed inside the storage tank 2, an stirring roller 32 fixed on the outside of the transmission rod 31, and a scraper 33 fixed on the outside of the transmission rod 31 through a connecting rod, and the outside of the scraper 33 is in contact with the inner wall of the storage tank 2.

[0040] Driven by the motor 19, the transmission rod 31 can drive the stirring roller 32 to rotate, stirring the repair material in the storage tank 2, preventing the material from settling and clumping, ensuring the uniformity of the material, and improving the repair quality. During the stirring process, the scraper 33 can scrape off the material adhering to the inner wall of the storage tank 2, reducing material waste and facilitating the cleaning of the storage tank 2.

[0041] Specifically, a motor 19 is installed on the outside of the storage tank 2. Both the output end of the motor 19 and the top end of the transmission rod 31 are fixed with bevel gears 20, and the two sets of bevel gears 20 mesh with each other. A protective cover 21 for protecting the bevel gears 20 is fixed on the inner wall of the storage tank 2.

[0042] The motor 19 serves as the power source for the stirring component 3. Its output end can drive the bevel gear 20 to rotate. Through the transmission of the two sets of bevel gears 20, the rotational motion of the motor 19 can be transmitted to the transmission rod 31 to realize the transmission and direction of power. This allows the transmission rod 31 to drive the stirring roller 32 and the scraper 33 to rotate. The protective cover 21 is set to protect the bevel gear 20, preventing repair materials from entering the meshing part of the bevel gear 20 and affecting the normal transmission of the bevel gear 20. At the same time, it can also protect the bevel gear 20 from material corrosion and extend its service life.

[0043] Working principle: When using this troweling device, first open the sealing cover 15, pour the repair material for repairing cracks in railway bridges into the storage tank 2, close the sealing cover 15, and lock it with the locking piece 16 to ensure a tight seal. Then, start the motor 19. The output end of the motor 19 drives the bevel gear 20 to rotate. Through the meshing transmission of the two sets of bevel gears 20, the power is transmitted to the transmission rod 31. The transmission rod 31 drives the stirring roller 32 and the scraper 33 to rotate, stirring the repair material in the storage tank 2 to prevent the material from settling and clumping. At the same time, during the stirring process, the scraper 33 rotates to scrape off the material adhering to the inner wall of the storage tank 2. Then, the operator can push the push rod 12 and use the moving wheels 11 to move the device. Move to the location of the crack that needs repair. Upon arrival, rotate the turntable at the top of the threaded rod 9 according to actual needs, causing the threaded rod 9 to move up and down within the fixed frame 6. This moves the scraper 8 to a suitable height. The corrugated pipe 10 prevents dust and debris from entering the threaded connection. Then, open the control valve 18, and the repair material is discharged to the crack through the discharge pipe 17. Rotate the screw 54, which causes the movable block 53 to move up and down within the limit frame 51. Adjust the position of the pressure roller 4 to roll the repair material applied to the crack, ensuring that the material tightly fills the crack. At the same time, during the movement of the device, the scraper 8 scrapes the repair material to make the surface smooth, ensuring that the railway bridge crack repair work is completed efficiently and with high quality.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
