[0024] 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.

[0025] Please see Figures 1-7 This utility model provides an embodiment: a bridge and tunnel maintenance tool cart, including a structural chassis plate 1, a tool storage box 401, and a ground maintenance and cleaning component. The upper end of the structural chassis plate 1 is equipped with a tool cart body 2, and drive wheels 3 are provided on both sides of the structural chassis plate 1. The lower end of the structural chassis plate 1 is equipped with a ground maintenance and cleaning component. The tool cart body 2 has a storage compartment 4 inside, and the tool storage box 401 is rotatably connected to the inner wall of the storage compartment 4. The tool storage box 401 has four partitions 402 inside, and folding connecting rods 403 are rotatably connected to both sides of the inner wall of the storage compartment 4. The lower ends of the folding connecting rods 403 are rotatably connected to both sides of the tool storage box 401.

[0026] The tool cart body 2 is rotatably connected to two sides of a movable plate 404. A hollowed-out connecting plate 405 is fixed to the outer end face of the tool storage box 401. The movable plate 404 is snapped into the interior of the hollowed-out connecting plate 405. The hollowed-out connecting plate 405, together with the movable plate 404, can be fixed after the tool storage box 401 is stored in the storage compartment 4 to prevent the tool storage box 401 from falling out of the tool cart body 2.

[0027] The ground maintenance and cleaning components include a cleaning shovel 101, an electric telescopic rod 102, a rotating paddle roller 103, a dust collection bin 104, an industrial vacuum pump 105, a pointed vacuum hollow plate 106, a bin door 107, a transmission sleeve 108, a belt 109, a water storage bin 110, an inlet pipe 111, a pressurized water pump 112, a water guide plate 113, and a nozzle 114. The cleaning shovel 101 is hinged to the bottom end of the structural chassis plate 1, and the electric telescopic rod 102 is hinged to the inner wall of the bottom end of the structural chassis plate 1. The electric telescopic rod 102 can flexibly adjust the angle and height of the cleaning shovel 101 to adapt to different ground conditions.

[0028] The output end of the electric telescopic rod 102 is hinged to both sides of the cleaning shovel plate 101. The bottom inner wall of the structural chassis plate 1 is rotatably connected to the rotating paddle roller 103, which is positioned above the cleaning shovel plate 101. The tool carriage 2 is equipped with a dust collection chamber 104. The rotating paddle roller 103 is linked to the drive wheel 3 through the transmission sleeve 108 and belt 109. The power of the vehicle's movement drives the rotating paddle roller 103 to rotate, pushing the silt or other debris scraped up by the cleaning shovel plate 101 toward the rear nozzle-type vacuum hollow plate 106.

[0029] An industrial dust pump 105 is installed on the top surface of the tool cart body 2. The output pipe of the industrial dust pump 105 is connected to the interior of the dust collection bin 104. A pointed nozzle vacuum hollow plate 106 is connected to the lower end of the structural chassis plate 1. The upper end pipe of the pointed nozzle vacuum hollow plate 106 is connected to the interior of the dust collection bin 104. The pointed nozzle vacuum hollow plate 106 is located on the side of the cleaning shovel plate 101. A bin door 107 is opened on the side end of the tool cart body 2. The pointed nozzle vacuum hollow plate 106 sucks up debris or sludge into the dust collection bin 104 for collection. The bin door 107 can be used to remove the sludge and debris after collection.

[0030] Both the central shaft of the rotating paddle roller 103 and the central shaft of the drive wheel 3 are fixedly connected to transmission sleeves 108. The two transmission sleeves 108 are externally connected to belts 109. The tool carriage 2 is equipped with a water storage tank 110. The top surface of the tool carriage 2 is equipped with an inlet pipe 111. The lower end of the inlet pipe 111 extends into the water storage tank 110. When the drive wheel 3 rotates, it drives the rotating paddle roller 103 to rotate through the transmission sleeves 108 and belts 109, which raises the fine particles and dust remaining after the cleaning shovel 101 is scooped up.

[0031] A pressurized water pump 112 is installed at the bottom of the structural chassis plate 1. The inlet pipe of the pressurized water pump 112 is connected to the inside of the water storage tank 110, and the outlet pipe of the pressurized water pump 112 is connected to a water guide plate 113. A nozzle 114 is provided on the side end of the water guide plate 113. After the pressurized water pump 112 pressurizes the water in the water storage tank 110, it is sprayed out from the nozzle 114 through the water guide plate 113, which can be used to clean the ground or spray maintenance agents.

[0032] Working principle: According to Figures 1-2First, when tools are needed, pull the tool storage box 401, unfold the folding rod 403, and open the tool storage box 401. The four partitions 402 inside divide the space, making it convenient to classify and store different tools. After use, rotate the tool storage box 401 in the opposite direction, fold the folding rod 403, and the tool storage box 401 is put back into the storage compartment 4. At this time, the movable connecting plates 404 rotatably connected to both sides of the tool cart body 2 are snapped into the hollow docking plate 405 fixed to the outer end face of the tool storage box 401 to fix the tool storage box 401 and prevent it from shaking when the vehicle is moving.

[0033] according to Figures 3-7 Subsequently, when the electric telescopic rod 102 extends, it pushes the cleaning shovel 101 to rotate downwards, bringing it close to the ground. As the vehicle moves forward under the drive of the drive wheel 3, the cleaning shovel 101 can remove larger debris from the ground. The two transmission sleeves 108 are connected by a belt 109. Therefore, when the drive wheel 3 rotates, the transmission sleeves 108 and belt 109 drive the rotating paddle roller 103 to rotate, pushing the silt and dust shoveled up by the cleaning shovel 101 towards the rear nozzle-type vacuum hollow plate 106. Then, the industrial vacuum pump 105 starts to generate suction, which sucks the dust and debris raised into the dust collection chamber 104 through the nozzle-type vacuum hollow plate 106. When the debris in the dust collection chamber 104 needs to be cleaned, the door 107 opened on the side end of the tool cart body 2 can be opened.

[0034] It should be noted that the electric telescopic pole 102, industrial vacuum pump 105 and pressurized water pump 112 can be powered by existing operating techniques. Whether powered by a power supply device or by an external wire, they are all conventional operating techniques and will not be described in detail here.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
