Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance technology, and more specifically, to a rapid cleaning device for bridge expansion joints. Background Technology

[0002] Bridge expansion joints are a critical component of bridge structures. Their core function is to accommodate the expansion and contraction of the bridge under the influence of factors such as temperature changes, vehicle loads, and foundation settlement, preventing stress concentration that could lead to cracks, displacement, or even failure of the main bridge structure, while ensuring the smoothness and safety of vehicle traffic. However, during long-term bridge operation, the gaps in expansion joints can easily become accumulation areas for various debris, posing a potential threat to the structural safety of the bridge. (See website: [website address missing]) https: / / v.douyin.com / vv_JWHURluo / , a video about cleaning bridge expansion joints.

[0003] Currently, cleaning bridge expansion joints requires workers to use brooms, hooks, and small shovels to clean debris from the joints one by one. After cleaning, dust, stones, and other debris must be collected, resulting in low efficiency and strenuous work. Therefore, we propose a rapid cleaning device for bridge expansion joints. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rapid cleaning device for bridge expansion joints to solve the technical problems of low efficiency and high labor intensity in cleaning bridge expansion joints.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid cleaning device for bridge expansion joints, comprising a cleaning trolley and a cleaning mechanism mounted on the cleaning trolley. The cleaning trolley includes a collection box, and a battery is mounted on the bottom of the collection box. The cleaning mechanism includes mounting plates symmetrically arranged on the front of the collection box. A rotating shaft is rotatably mounted on the mounting plate, and a mounting plate is arranged between the rotating shafts. Connecting rods are arranged in an array on the mounting plate, and cleaning components are provided at the ends of the connecting rods. Collection slots for collecting debris cleaned by the cleaning components are symmetrically mounted on the collection box.

[0006] Preferably, the bottom of the collection box is symmetrically and rotatably mounted with axles, and movable wheels are symmetrically arranged on the axles. A push rod is provided on the back of the collection box.

[0007] Preferably, the mounting plate is provided with an L-shaped fixing plate, and sprockets are provided on both the rotating shaft and the front of the fixing plate. A transmission chain is provided between the sprockets, and a motor for driving the sprockets is provided on the back of the fixing plate.

[0008] Preferably, the cleaning component includes a cleaning section, a collecting section, and a triangular section in sequence along its long axis. The cleaning section has a U-shaped cross-section and is arc-shaped along its long axis. The collecting section is a box-shaped structure connected to the cleaning section, and the top surface of the collecting section is open.

[0009] Preferably, the triangular portion is disposed at the top of the collecting portion, and baffles are symmetrically disposed on the side ends of the triangular portion, and a discharge port is formed between the triangular portion and the collecting portion.

[0010] Preferably, the collecting trough includes a collecting section, a bending section, and a discharging section in sequence along its long axis. The height of the collecting trough gradually decreases along its long axis. The bending section is curved in an arc shape toward the collecting box, and the tail of the discharging section is located inside the collecting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of the cleaning component structure, allows the device to perform cleaning work simply by manually pushing it along the bridge expansion joint. The cleaning part of the cleaning component adopts a U-shaped cross-section and an arc-shaped long axis design, which can fit against the inner wall of the joint to thoroughly scrape away debris such as gravel and mud. The box-shaped opening structure of the collection part can immediately receive the debris after cleaning, preventing the debris from falling back into the joint and reducing repeated cleaning work, further reducing the frequency of manual intervention. The triangular part at the top of the cleaning component and the baffle form a directional discharge port. When the cleaning component rotates to the top with the installation plate, the debris can be accurately discharged to both sides along the discharge port and fall into the symmetrically set collection troughs, effectively improving the cleaning efficiency of bridge expansion joints and solving the current problems of low efficiency and high labor intensity in cleaning bridge expansion joints.

[0012] 2. This utility model also features a design structure in which the height of the collection trough gradually changes along its long axis. Combined with the arc-shaped structure of the curved part, gravity can be used to allow debris to slide naturally into the collection box, avoiding accumulation and blockage in the trough. The tail of the discharge part extends into the inside of the collection box, allowing the discharged debris to fall directly into the collection box without the need for separate manual collection. This significantly shortens the operation process, effectively reduces workload, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 7 As shown, this utility model relates to a rapid cleaning device for bridge expansion joints, including a cleaning trolley 100 and a cleaning mechanism 200 mounted on the cleaning trolley 100. The cleaning trolley 100 includes a collection box 101, with a battery 102 mounted on the bottom surface of the collection box 101. The battery 102 is made of metal, which can effectively lower the overall center of gravity of the device and prevent the cleaning mechanism 200 from tipping over or tilting forward due to vibration or weight during operation, thus ensuring stability during operation. The cleaning mechanism 200 includes mounting plates 201 symmetrically arranged on the front of the collection box 101. A rotating shaft 202 is rotatably mounted on the mounting plate 201, and a mounting plate 203 is arranged between the rotating shafts 202. Connecting rods 204 are arranged in an array on the mounting plate 203, and cleaning components 205 are provided at the ends of the connecting rods 204. Collection grooves 301 for collecting debris cleaned by the cleaning components 205 are symmetrically mounted on the collection box 101. This utility model uses a motor 207 to drive the cleaning mechanism 200 to operate. The U-shaped arc cleaning part 2051 can scrape away debris. The material collection part 2052, the triangular part 2053, the discharge port 2055 and the gradually increasing height collection groove 301 work together to achieve immediate collection of debris. No secondary operation is required. It can be operated by a single person, which greatly improves cleaning efficiency and reduces labor intensity.

[0016] Specifically, axles 103 are symmetrically mounted on the bottom of the collection box 101, and movable wheels 104 are symmetrically arranged on the axles 103. A push rod 105 is provided on the back of the collection box 101. During cleaning, the device can be moved along the bridge expansion joint by pushing the push rod 105 in conjunction with the movable wheels 104, thereby carrying out the cleaning work.

[0017] Furthermore, an L-shaped fixing plate is provided on the mounting plate 201. Sprockets 206 are provided on both the rotating shaft 202 and the front of the fixing plate, and a transmission chain is provided between the sprockets 206. A motor 207 driving the sprockets 206 is provided on the back of the fixing plate. The battery 102 is electrically connected to the motor 207, supplying power to the motor 207. The motor 207 drives the sprockets 206 to rotate clockwise. The sprockets 206 are linked by the transmission chain, thereby causing the sprockets 206 on the axle 103 to rotate, thus activating the cleaning mechanism 200 to perform cleaning work.

[0018] It is worth noting that the cleaning component 205 includes, along its long axis, a cleaning section 2051, a collecting section 2052, and a triangular section 2053. The cleaning section 2051 has a U-shaped cross-section and is arc-shaped along its long axis. The collecting section 2052 is a box-shaped structure connected to the cleaning section 2051, with an opening on its top surface. The U-shaped cross-section of the cleaning section 2051 is adapted to the width of common bridge expansion joints. The arc-shaped design allows it to fit more closely to the inner wall of the expansion joint during rotation, effectively scraping away debris such as gravel and silt from the joint. During movement, the debris cleaned by the cleaning section 2051 moves backward, and the opening on the top surface of the collecting section 2052 allows the scraped debris to enter smoothly, preventing it from falling back into the expansion joint during the cleaning process.

[0019] It is worth noting that the triangular portion 2053 is located at the top of the collecting portion 2052, and baffles 2054 are symmetrically arranged on the sides of the triangular portion 2053. A discharge port 2055 is formed between the triangular portion 2053 and the collecting portion 2052. During the cleaning process, the baffles 2054 can prevent debris in the collecting portion 2052 from falling from the side when the device moves or the cleaning component 205 rotates. When the cleaning component 205 containing debris moves to the top, the triangular portion 2053 will face downward, and the debris in the collecting portion 2052 will be discharged from the discharge ports 2055 on both sides of the triangular portion 2053. The discharged debris moves to the outside of the cleaning mechanism 200.

[0020] It is worth noting that the collection trough 301 includes, along its long axis, a collection section 302, a bending section 303, and a discharge section 304. The height of the collection trough 301 gradually decreases along its long axis. The bending section 303 bends in an arc shape towards the collection box 101, and the tail of the discharge section 304 is located inside the collection box 101. Debris discharged from the discharge port 2055 falls into the collection trough 301. Due to the gradually decreasing height of the collection trough 301 combined with the arc-shaped structure of the bending section 303, gravity allows the debris to slide naturally within the collection trough 301, preventing accumulation and blockage. The tail of the discharge section 304 extends into the collection box 101, allowing debris to enter the collection box 101, avoiding the need for re-collection after cleaning and effectively improving cleaning efficiency.

[0021] Working Principle: This embodiment provides a rapid cleaning device for bridge expansion joints. In use, the push rod 105 on the back of the collection box 101 is first pushed, cooperating with the symmetrically mounted moving wheels 104 on the bottom axle 103 of the collection box 101, causing the entire device to move smoothly along the extension direction of the bridge expansion joint. During the movement, the motor 207 operates, causing the sprocket 206 to rotate. The two sprockets 206 are connected by a transmission chain, thereby driving the rotating shaft 202 to rotate synchronously on the mounting plate 201. The rotation of the rotating shaft 202 causes the mounting plate 203 fixed therebetween to rotate. The connecting rods 204 arrayed on the mounting plate 203 move in a circular motion along with the mounting plate 203, thereby driving the cleaning component 205 at the end of the connecting rods 204 to rotate synchronously. During the rotation of the cleaning component 205, its cleaning part 2051 (with a U-shaped cross-section and an arc shape along the long axis, and dimensions adapted to the width of common bridge expansion joints) extends deep into the expansion joint, adhering to the inner wall of the expansion joint to thoroughly scrape away gravel, mud, and other debris in the gap. The scraped debris moves backward under the inertia of the cleaning component 205 and enters the space connected to the cleaning part 2051 through the opening on the top surface of the collection part 2052. Inside the box-shaped collection section 2052, a baffle 2054 at the side of the triangular portion 2053 at the top of the collection section 2052 prevents debris from spilling from the side. As the cleaning component 205 continues to rotate with the mounting plate 203 to the upper position of the device, the triangular portion 2053 faces downwards, and the debris in the collection section 2052 is discharged from the discharge port 2055 formed between the triangular portion 2053 and the collection section 2052 under the action of gravity. Because the triangular portion 2053 is designed to allow the debris to be discharged to both sides, the discharged debris falls precisely into the collection troughs 301 symmetrically installed on the collection box 101. The collection troughs 301 are along the long axis. The height gradually decreases, and the middle curved part 303 bends in an arc towards the collection box 101. After the debris enters the collection trough 301, it slides naturally along the collection part 302 and the curved part 303 to the discharge part 304 under the action of gravity. Finally, it falls into the collection box 101 through the tail of the discharge part 304 that extends into the collection box 101 to complete the collection. During the cleaning process, the battery 102 set on the bottom of the collection box 101 can power the motor 207, realizing continuous operation of moving, cleaning and collecting at the same time. There is no need for manual collection of debris later, which significantly improves the cleaning efficiency and reduces the workload.
