Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, and in particular to a cleaning device for steel box girders after construction. Background Technology

[0002] Steel box girders are widely used in bridge engineering, especially for long-span bridges. Due to their lightweight, high strength, high stability, and good wind and earthquake resistance, they have become important components in engineering fields such as highways, urban rail transit, railways, and airports.

[0003] During the construction of steel box girders, various coatings and adhesives are used. These materials, during the drying process, can produce residues such as those from concrete bonding agents and dust. If not cleaned promptly, these residues can affect the appearance and quality of the steel box girder, leading to spots or stains. Furthermore, a clean surface ensures good adhesion between the coating and the substrate when applying anti-corrosion coatings or undergoing other surface treatments, thereby improving the coating's durability and protective effect.

[0004] As mentioned above, due to the complex structure of steel box girders, traditional steel box girder cleaning work relies on manual high-pressure water guns for initial cleaning. For concrete lumps or rust, manual removal tools are then used to clean them, resulting in low efficiency and high risk of working at heights.

[0005] In addition, due to the complex structure of steel box girders, most existing cleaning equipment adopts a fixed cleaning structure, which makes it difficult to clean areas such as U-shaped ribs, partitions, and corners. In severe cases, it can cause local damage to the steel box girder during the cleaning process, reducing its strength and stability. Utility Model Content

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] This embodiment relates to a post-construction cleaning device for steel box girders. Overall, as follows... Figure 1 and Figure 2 As shown, the cleaning device includes a traveling mechanism 1, a drive mechanism 2 mounted on the traveling mechanism 1, a cleaning component 3 mounted on the movable end of the drive mechanism 2, and a wastewater collection component 4 connected to the cleaning component 3. The traveling mechanism 1 has a collection tank 101 communicating with the wastewater collection component 4. The drive mechanism 2 drives the cleaning component 3 to reciprocate along the width direction of the traveling mechanism 1. The cleaning component 3 includes a water supply pipe 301, and several rust removal sections 302 and spray sections 303 connected below the water supply pipe 301, with the rust removal sections 302 and spray sections 303 arranged alternately. The collection tank 101 has an outlet 1012 communicating with the water supply pipe 301, and a filter section is provided inside the collection tank 101.

[0051] The steel box girder post-construction cleaning device of this embodiment uses a walking mechanism 1 to drive a drive mechanism 2, a cleaning component 3, and a wastewater collection component 4 to move along the surface of the steel box girder for cleaning. The drive mechanism 2 drives the cleaning component 3 to move back and forth along the width direction of the walking mechanism 1, i.e., to clean in a direction perpendicular to the walking direction. This avoids interference with U-shaped ribs, partitions, etc., on the steel box girder and allows it to reach into gaps for cleaning, reducing cleaning dead zones and improving cleaning efficiency. Simultaneously, a rust removal section 302 is installed below the water supply pipe 301 to remove rust from the steel box girder. The rust removal section 302 is then rinsed by a spray section 303 adjacent to it, further improving the cleaning effect. Finally, the wastewater collected by the wastewater collection component 4 is filtered through a filter in the collection tank 101 and then returned to the water supply pipe 301 for recycling. This not only reduces waste of cleaning water but also ensures a clean construction environment for the steel box girder.

[0052] Based on the above overall structure, such as Figures 1 to 2 As shown, the cleaning device has a simple structure, is easy to carry, and can meet the needs of construction sites. For cleaning the sides or bottom of steel box girders, track wheels can be installed on the steel box girder, and a magnetic tracked vehicle can be used to automatically move along the longitudinal or transverse direction of the steel box girder, which is suitable for cleaning the entire steel box girder.

[0053] As a preferred embodiment, such as Figures 1 to 2 As shown, the traveling mechanism 1 includes a traveling frame 102, an engine mounted on the traveling frame 102, and a track drive assembly 103. A collection bucket 101 is mounted on the traveling frame 102. The engine drives the track drive assembly 103 to move, so that the cleaning device travels along the steel box girder. In this embodiment, the engine is a diesel engine, and the track drive assembly 103 includes a gearbox, clutch, drive shaft, and tracks. This traveling mechanism 1 can be referenced from tracked vehicles in the prior art.

[0054] In addition, such as Figure 1 As shown, the walking frame 102 is equipped with a first drive unit 104. The power output end of the first drive unit 104 is connected to a fixed plate 105. The fixed plate 105 is located above the track drive assembly 103, and the drive mechanism 2 is located on the fixed plate 105. The first drive unit 104 is a servo motor. The first drive unit 104 drives the fixed plate 105 to rotate, thereby adjusting the angle of the water pipe 301, which facilitates cleaning gaps at different angles.

[0055] Preferably, such as Figure 3 and Figure 4As shown, the drive mechanism 2 includes a second drive unit 201 pivotally connected to the middle of the fixed plate 105, a turntable 202 at the power output end of the second drive unit 201, and an upwardly protruding post 203 on the turntable 202. The fixed plate 105 has two opposing supports 204, and a reciprocating member 205 is slidably connected to each support 204, the reciprocating member 205 being sleeved on the outside of the post 203. When the turntable 202 rotates, the reciprocating member 205 reciprocates along the width direction of the traveling frame 102. The second drive unit 201 is fixedly connected to the fixed plate 105 and uses a servo motor.

[0056] Furthermore, such as Figure 3 and Figure 4 As shown, the turntable 202 is provided with a guide rail 206 and a guide block 207 adapted to be connected to the guide rail 206. A protrusion 203 is connected to the guide block 207. The guide rail 206 is arranged radially along the turntable 202. The guide rail 206 is provided with a third driving part 208. The third driving part 208 drives the guide block 207 to slide along the extension direction of the guide rail 206, so that the protrusion 203 approaches or moves away from the center of the turntable 202. In this embodiment, the third driving part 208 is a telescopic cylinder. In this embodiment, the guide block 207 is formed with an inverted V-shaped groove, and the guide rail 206 is formed with an inverted V-shaped protrusion that matches the groove.

[0057] By activating the third drive unit 208, the position of the guide block 207 relative to the guide rail 206 is adjusted, thereby driving the distance between the protrusion 203 and the center of the turntable 202. When the turntable 202 rotates, the length of the reciprocating stroke of the guide post 2052 can be adjusted to meet the needs of different cleaning positions, thereby saving cleaning time and improving cleaning efficiency.

[0058] In addition, such as Figure 4 As shown, the reciprocating component 205 includes a sleeve plate 2051 and guide posts 2052 connected to both sides of the sleeve plate 2051. A receiving hole is provided on the support 204 to accommodate the guide posts 2052, and the guide posts 2052 slide along the axis of the receiving hole. A long groove 2053 is formed inside the sleeve plate 2051, and the width of the long groove 2053 is adapted to the diameter of the protrusion 203. In this embodiment, the sleeve plate 2051 is elongated with arc segments at both ends, further improving the smoothness of the rotation of the protrusion 203. Furthermore, in this embodiment, the inner hole 601 of the long groove 2053 of the sleeve plate 2051 and the outer circle of the protrusion 203 are ground to further improve the flexibility of the reciprocating component 205's movement.

[0059] In this embodiment, as Figure 5As shown, several connecting columns 5 and water delivery columns 6 are provided below the water supply pipe 301. Connecting plates 7 are respectively provided on the connecting columns 5 and water delivery columns 6. The rust removal section 302 and the spraying section 303 are arranged on their respective connecting plates 7. By providing connecting plates 7, the installation of the rust removal section 302 and the spraying section 303 is facilitated. In this embodiment, the spraying section 303 adopts a high-pressure rotary nozzle, and the rust removal section 302 can adopt equipment such as a laser rust removal machine or an angle grinder.

[0060] Preferably, such as Figure 5 As shown, a pipe 3011 is provided in the extending direction of the water supply pipe 301. An inner hole 601 communicating with the spray section 303 is formed inside the water supply column 6. The pipe 3011 communicates with the inner hole 601 and with the outlet 1012 of the collection tank 101. In this embodiment, the filter section provided inside the collection tank 101 can employ multi-layer filter screens to filter concrete or steel slag, thereby improving the water cleanliness at the outlet 1012 of the collection tank 101.

[0061] In addition, for ease of installation and connection, a support plate 8 is connected to one side of each connecting plate 7. The sewage collection assembly 4 includes a suction nozzle 9 connected to the support plate 8. The inlet of the suction nozzle 9 is located at the rear of the spray section 303 and the rust removal section 302. The outlet of the suction nozzle 9 is connected to a suction pipe 10. The outlet of the suction pipe 10 is connected to the inlet 1011 of the collection tank 101. A pump body 11 is provided on the suction pipe 10. In this embodiment, the support plate 8 adopts a long strip plate structure, and the suction nozzle 9 extends along the length of the support plate 8. The suction nozzle 9 is formed by bending and welding sheet metal, and its inlet is conical.

[0062] The inlet end of the suction nozzle 9 abuts against the steel box girder. When moving, the front spray section 303 and rust removal section 302 clean after rust removal, and the suction nozzle 9 located at the rear can suck in sewage through the suction force of the pump body 11.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
