Description

Technical Field

[0001] This utility model relates to the field of beam bridge maintenance technology, specifically a maintenance device for hollow slab beam bridges. Background Technology

[0002] With the rapid advancement of infrastructure construction in my country, bridge engineering construction technology is advancing by leaps and bounds. Bridge maintenance has two meanings. In a narrow sense, bridge maintenance refers to the inspection, testing, evaluation, repair and reinforcement work carried out to ensure that bridges are always in normal working condition. In a broad sense, bridge maintenance also includes other indirect measures taken to ensure the safe operation of bridges, such as data and archive management, the establishment of relevant systems and regulations, and the establishment of emergency plans.

[0003] A maintenance device for hollow slab beam bridges, disclosed in publication CN 210177378 U, includes a base plate and a fixed plate. A water tank is fixedly connected to the upper surface of the base plate, and a dust collection box and a suction fan are fixedly connected to the upper surface of the water tank. The input end of the suction fan is fixedly connected to the side wall of the dust collection box. Rectangular through holes are opened at the same positions on the lower surface of the dust collection box and the upper surface of the water tank, and filter screens are fixedly connected to the walls of the rectangular through holes. A motor is fixedly connected to the upper surface of the fixed plate, and the output end of the motor passes through the fixed plate and is fixedly connected to a stirring rod. Multiple stirring blocks are fixedly connected to the wall of the stirring rod, and a sealed bearing is fixedly sleeved on the outer wall of the stirring rod. This utility model can effectively improve the efficiency of bridge drainage pipe dredging, and the dredging process is time-saving and labor-saving, reducing the labor intensity of workers. It also improves the efficiency of bridge maintenance, saves water, and avoids water waste.

[0004] However, the above-mentioned devices still have some shortcomings in use. They are not convenient for cleaning the expansion joints of beam bridges. Expansion joints are opened on the surface of beam bridges during the paving process. When vehicles are driving, mud, sand and debris fall into the bridge expansion joints. If not dealt with in time, the expansion joints will become silted up and blocked, which will affect the normal expansion and contraction of the bridge. In severe cases, it may even endanger the safety of the beam bridge. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a maintenance device for hollow slab beam bridges, which solves the problem of inconvenient cleaning of the expansion joints of beam bridges. Expansion joints are opened on the surface of beam bridges during paving. When vehicles travel, mud, sand and debris fall into the bridge expansion joints. If not dealt with in time, the expansion joints will accumulate and become blocked, thereby affecting the normal expansion and contraction of the bridge, and in severe cases, it may even endanger the safety of the beam bridge.

[0006] This utility model provides the following technical solution: a maintenance device for hollow slab beam bridges, including a support plate, a slot in the middle of the support plate, two vertical plates fixedly connected to the upper surface of the support plate, grooves on opposite sides of the two vertical plates, a threaded rod rotatably connected between the top and bottom walls of one of the grooves, a threaded sleeve threaded onto the surface of the threaded rod, a sliding rod fixedly connected between the top and bottom walls of the other groove, a sliding sleeve slidably fitted onto the surface of the sliding rod, a connecting plate fixedly connected between the sliding sleeve and the threaded sleeve, two connecting rods fixedly connected to the lower surface of the connecting plate, sweeping rods rotatably connected to opposite sides of the two connecting rods, a sweeping disc fixedly connected between the two sweeping rods, a ring of paddles fixedly installed on the surface of the sweeping disc, bristles on the surface of the two sweeping rods, a drive motor fixedly connected to the side of one of the connecting plates, the output end of the drive motor passing through the connecting plate and fixedly connected to the sweeping rods.

[0007] Preferred technical solution 1: A first motor is fixedly connected to the upper surface of one of the vertical plates, and the output end of the first motor passes through the connected vertical plate and is fixedly connected to the threaded rod.

[0008] This solution uses the rotation of the first motor to drive the threaded rod, connecting plate, and cleaning disc to rise and fall, facilitating cleaning.

[0009] Preferred technical solution 2: A high-pressure blower is fixedly installed on the upper surface of the support plate, the air outlet end of the high-pressure blower is connected to an air outlet pipe, one end of the air outlet pipe is connected to a spray head, and the spray head is fixedly connected to the connecting plate.

[0016] This solution allows users to easily control each component and facilitates operation.

[0017] Compared with the prior art, this utility model provides a maintenance device for hollow slab beam bridges, which has the following beneficial effects: In use, the device is moved to the expansion joint of the bridge by pushing the handle and the movable wheel, and the cleaning disc is aligned with the expansion joint. Then, the screw rod of the first motor is rotated, thereby driving the threaded sleeve to move, which in turn drives the connecting plate and the cleaning disc to move downward, so that the cleaning disc penetrates into the interior of the expansion joint. At the same time, the two cleaning rods and the blower head are moved to a position close to the ground. Then, the high-pressure blower and the blower head work together to blow out small particles of dust and other impurities inside the expansion joint. Then, the rotation of the drive motor drives the cleaning disc to rotate, and the action of the paddles pushes out large particles such as stones inside the expansion joint. Then, the cleaning rods sweep the dust into the dust collection hood, and the vacuum cleaner absorbs the dust and other debris generated during the cleaning process, preventing dust and other garbage from flying everywhere and ensuring cleanliness.

[0024] Example 2: The difference between this example and Example 1 is that a first motor 13 is fixedly connected to the upper surface of one of the vertical plates 2. The output end of the first motor 13 passes through the connected vertical plate 2 and is fixedly connected to the threaded rod 4. The rotation of the first motor 13 drives the threaded rod 4, the connecting plate, and the cleaning disc 11 to rise and fall, which facilitates cleaning.

[0025] Example 3: The difference between this example and Example 1 is that a high-pressure blower 14 is fixedly installed on the upper surface of the support plate 1.

[0029] In summary, the maintenance device for hollow slab beam bridges is used by moving the device to the bridge's expansion joint by pushing the handrail and movable wheels 20, aligning the cleaning disc 11 with the expansion joint, and then controlling the rotation of the threaded rod 4 of the first motor 13 to rotate, thereby moving the threaded sleeve 5, which in turn moves the connecting plate 8 and the cleaning disc 11 downwards, allowing the cleaning disc 11 to penetrate deep into the expansion joint. At the same time, the two cleaning rods 10 and the blower head 16 move to a position close to the ground. Then, the high-pressure blower 14 and the blower head 16 work together to blow out small particles of dust and other impurities from inside the expansion joint. Then, the rotation of the drive motor 12 drives the cleaning disc 11 to rotate, and the action of the paddles removes large particles such as stones from inside the expansion joint. Then, the cleaning rods 10 sweep the particles into the dust collection hood 19, and the vacuum cleaner 17 absorbs the dust and other debris generated during the cleaning process, preventing dust and other debris from flying everywhere and ensuring cleanliness.
