[0023] Specifically, two extension brackets 7 are respectively provided at both ends of the top of both sides of the support frame 1 , and the two extension brackets 7 are respectively located above the ballast retaining wall 3 , and the bottom of the extension bracket 7 is connected to the first moving wheel 2 .

[0024] Specifically, two second moving wheels 6 are respectively arranged at both ends of the bottom of the support frame 1, and the second moving wheels 6 are slidably connected to the side surface of the ballast retaining wall 3. The second moving wheels 6 are perpendicular to the side surface of the ballast retaining wall, and their function is to prevent the first moving wheels from detaching from the top surface of the ballast retaining wall when the coating trolley is moving.

[0025] As a preferred embodiment, a limit plate 9 is detachably provided on one side of each extension bracket 7, and the limit plate 9 is in contact with the outer wall of the ballast retaining wall 3. A slide groove is provided at the bottom of the extension bracket 7, and a slider is provided on the top of the limit plate 9. The slide groove is adapted to the slider, and a detachable connection is achieved through the slide groove slider. The limit plate 9 is located on the outer side of the ballast retaining wall, and its function is to prevent the first moving wheel from being separated from the top surface of the ballast retaining wall when the coating trolley is moving.

[0026] Specifically, the laminating assembly includes a laminating reel frame 4 and a laminating pressure roller 5, wherein the laminating reel frame 4 is arranged at the bottom of the support frame 1, and the laminating pressure roller 5 is arranged below the laminating reel frame 4. Two laminating reel frames 4 are symmetrically arranged at the bottom of the support frame 1, and two laminating pressure rollers 5 are symmetrically arranged below the laminating reel frames 4.

[0027] As a preferred embodiment, the laminating roller 5 is made of rubber material to avoid damage to the film.

[0028] like Figure 2 When in use, the coating trolley is designed according to the width of the box girder deck, the drawn design drawings are handed over to professional manufacturers for processing, the initially formed coating trolley is transported to the construction site, and the span, left and right height, and coating reel frame are adjusted to a suitable state; the support frame of the coating trolley after debugging is located on both sides of the bridge deck, and the two first moving wheels are placed on the ballast retaining walls on both sides. The ballast retaining walls on both sides of the straight section are at the same height, and the coating trolley is directly installed. The height difference between the inner and outer ballast retaining walls of the curved section is 180mm. During installation, the height of both sides of the coating trolley must be adjusted to the same height as the ballast retaining wall before construction can be carried out.

[0029] The film material is installed on the film roll frame drum. One person stands on the film covering trolley to install the plastic film. Two people move forward at a uniform speed to cover the completed concrete surface with plastic film. Two people use a long-handled roller brush to deal with the film bubbles and sprinkle water on the concrete surface for maintenance. After the strength increases, two people start to cover the water-retaining geotextile to protect the plastic film. According to the bridge deck system construction plan, the concrete protective layer is cured for 14 days and then the water-retaining geotextile is recycled. The forward speeds of the left and right wheels must match. After the construction is completed, the left and right wheels of the trolley must be locked to prevent the vehicle from slipping when unattended. After covering the plastic film, sprinkle water in time and cover the water-retaining geotextile to prevent the plastic film from being scratched and reducing the maintenance quality.

[0030] Embodiment 2: A coating trolley for bridge deck concrete maintenance comprises a support frame 1, a first movable wheel 2 and a coating assembly; the support frame 1 is located above the bridge deck and the first movable wheels 2 are respectively arranged on both sides; the first movable wheels 2 are located on the top surfaces of the ballast retaining walls 3 on both sides of the bridge deck; a coating assembly is arranged at the bottom of the support frame 1.

[0031] Specifically, the support frame 1 is also composed of a plurality of detachably connected frames 8, and two extension brackets 7 are respectively arranged at the top ends of the two frames 8 on the left and right sides, and the two frames 8 on the left and right sides are close to the ballast retaining wall 3. A sub-port is arranged on the left side of each frame 8, and a female port is arranged on the right side. When the two frames 8 are spliced, the sub-port of one frame 8 is plugged into the female port of the other frame 8.

[0032] In Example 1, the support frame is an integral support frame suitable for the construction according to the width of the bridge deck, the height of the ballast retaining wall and the construction site. In Example 2, the support frame is spliced ​​by multiple detachably connected frames, and the support frame can be flexibly assembled and adjusted according to the span of different construction sites, which greatly improves the working efficiency.

[0033] Specifically, a driving motor is provided at the bottom of each extension bracket 7 , and the driving motor is transmission-connected to the first moving wheel 2 .

[0034] In Example 1, construction workers are required to push the coating trolley forward at a constant speed to cover the completed concrete surface with plastic film. In Example 2, the coating trolley is driven forward by a driving motor to cover the concrete surface with plastic film, which significantly improves the timeliness. After the concrete surface is finished, the plastic film can be covered in a short time to keep the newly constructed concrete surface moist and effectively block moisture evaporation.

[0035] The coating trolley of the present application can drive the entire coating trolley to move forward by an operator pushing the first moving wheel on the support frame to move on the ballast retaining wall and the second moving wheel to move on the side of the ballast retaining wall, or by driving the first moving wheel on the ballast retaining wall through a driving motor. The operator covers the completed concrete surface with a plastic film to keep the newly constructed concrete surface moist, effectively block moisture evaporation, improve coating efficiency, and shorten construction time.

[0036] This laminating trolley adopts independent design and is mainly composed of three parts. The first part is the support frame of the intermediate load-bearing structure for operators to stand and walk and adjust the width of the roller film. It is fixed with a rectangular and triangular frame; the second part is the laminating and pressing structure, which fixes plastic films of different sizes on the cylindrical laminating reel frame, and the rubber tube laminating roller is tied above the film for pressing; the third part is the moving wheel part at both ends of the trolley, which is composed of triangular aluminum alloy extension brackets welded on both sides of the intermediate load-bearing structure and the first moving wheel fixed under the extension bracket. This device can be adjusted according to the width of the bridge deck, and the entire bridge deck can be covered at one time. After the construction is completed, the coverage is tight, which greatly improves the quality of concrete maintenance.
