Description

Technical Field

[0001] This application relates to the field of construction and maintenance equipment technology, and in particular to a smart spray maintenance vehicle for track-mounted box girders. Background Technology

[0002] The intelligent spray curing vehicle for track-mounted box girders is a highly efficient piece of equipment specifically designed for the maintenance of railway box girders. It travels precisely along a pre-set track, stably covering all areas of the girder storage zone. This avoids the cumbersome and costly installation of tracks and water pipes required in traditional maintenance methods. In large-scale railway projects, box girder maintenance often involves setting up running tracks along small passageways in the storage zone in conjunction with spray pipes, which has many drawbacks. Construction sites often generate a large amount of dust, typically requiring intelligent spray curing vehicles for dust suppression.

[0003] Existing intelligent spraying maintenance vehicles used on construction sites have limited coverage areas due to the fixed nozzle positions and monotonous water spray path, affecting the dust control effect during construction. Furthermore, impurities in the water can clog the nozzles, reducing the spraying area and causing localized areas without water or with a thinner water flow. This results in some areas of the box girder not being adequately moistened, impacting the maintenance effect. Therefore, we propose a track-mounted intelligent spraying maintenance vehicle for box girders. Utility Model Content

[0004] To overcome the shortcomings of fixed nozzle positions and uniform water spray path shapes, which limit the area of ​​dust spraying and affect the dust control effect during construction, and the fact that impurities in the water can clog the nozzles during spraying, resulting in a reduced spraying area, localized areas without water or with a thinner water flow, and insufficient wetting of certain areas of the box girder, thus affecting the curing effect, the purpose of this utility model is to provide a modular precast box girder reinforcement binding frame to solve the above-mentioned deficiencies.

[0005] This application provides a track-mounted intelligent spray maintenance vehicle for box girders, including a vehicle body, a water tank, and a cable bobbin. The water tank is embedded in the upper surface of the vehicle body, and a filter mechanism is provided on the outer surface of the water tank. A cable bobbin is provided on one side of the vehicle body, and a cable is wound around the outer surface of the cable bobbin. The cable is electrically connected to the vehicle body. Spray heads are provided in the inner cavity of the vehicle body. A support mechanism is provided on the upper surface of the vehicle body. The filter mechanism includes a filter box, which is fixedly connected to the outer surface of the water tank and the inner cavity of the filter box is connected to the water tank. A connecting pipe is fixedly connected to the end of the filter box away from the water tank. A cover is engaged in the inner cavity of the connecting pipe. A filter screen is slidably connected to the inner cavity of the filter box. A sliding rod is fixedly installed on the outer surface of the filter screen, and a spring is sleeved on the outer surface of the sliding rod. A limit block is fixedly installed on the inner wall of the filter box.

[0006] Furthermore, the spring is located between the filter screen and the limiting block, the slide rod and the limiting block are slidably connected, there are two limiting blocks on one side of the inner wall of the filter box, and the filter screen is located in the middle of the two limiting blocks.

[0007] Furthermore, a water pump is installed inside the water storage tank, and the spray head consists of a nozzle and a conduit. The conduit away from the nozzle is connected to the water pump, and the conduit and the water storage tank are slidably connected. The conduit part is located inside the water storage tank.

[0008] Furthermore, the support mechanism includes a connecting plate, a storage rod rotatably connected to the inner cavity of the connecting plate, a lifting rod slidably connected to the inner cavity of the storage rod, a connecting frame fixedly installed at the top of the lifting rod, a motor slidably connected to the inner cavity of the connecting frame, a motor provided on the outer surface of the connecting frame, a gear frame slidably connected to the inner cavity of the connecting frame, a gear provided in the middle part of the connecting frame, sliders fixedly connected to both ends of the gear frame, a limit seat rotatably connected to the top of the slider, and a limit rod connected to the top of the limit seat by a thread.

[0009] Furthermore, the output end of the motor is sleeved with the gear, half of the gear is hollowed out, and the inner wall of the gear frame is provided with tooth blocks. The tooth blocks mesh with the gear, and the slider and the connecting frame are slidably connected.

[0010] Furthermore, there is a certain amount of friction between the storage rod and the connecting plate, a certain amount of friction between the lifting rod and the storage rod, and a certain amount of friction between the limiting seat and the slider.

[0011] The technical solution provided in this application has at least the following technical effects or advantages:

[0012] 1. Due to the adoption of a filtration mechanism, the problem of impurities in the water clogging the nozzles during the spraying process is effectively solved. Once the nozzles are clogged, the spraying range will be reduced, resulting in localized areas without water or with a thinner water flow. This will prevent certain areas of the box girder from being adequately moistened, affecting the curing effect. This utility model prevents dust and impurities from adhering to the outer surface of the filter screen through the filtration mechanism, thereby improving the filtration effect of the filter screen. At the same time, it prevents dust and impurities from entering the inner cavity of the water storage tank, avoiding clogging during spraying, improving the uniformity of spraying, and ensuring the curing effect of on-site construction.

[0013] 2. Due to the adoption of a support mechanism, this invention effectively solves the problem that existing intelligent spraying maintenance vehicles used on construction sites have fixed nozzle positions and a single spray path shape, resulting in a limited area for dust spraying and affecting the dust removal effect during construction. This utility model, through the support mechanism, allows for multi-directional adjustment of the nozzle position, making the spraying range meet the operational requirements and providing a certain degree of tolerance for the spraying area, thus ensuring the dust removal effect during construction.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example

[0022] Please see Figure 1 As shown, the intelligent spray curing vehicle for track-mounted box girders includes a vehicle body 1, a water tank 2, and a cable bobbin 4. The water tank 2 is embedded in the upper surface of the vehicle body 1, and a filter mechanism 3 is installed on the outer surface of the water tank 2. A cable bobbin 4 is installed on one side of the vehicle body 1, and a cable is wound around the outer surface of the cable bobbin 4. The cable is electrically connected to the vehicle body 1. A spray head 5 is installed in the inner cavity of the vehicle body 1, and a support mechanism 6 is installed on the upper surface of the vehicle body 1. During spray curing, the water tank 2 is used to store the water required for spraying, and the filter mechanism 3 is used to filter the water stored in the water tank 2. The cable wound on the cable bobbin 4 facilitates the connection of an external power source to the vehicle body 1. The spray head 5 is clamped above the support mechanism 6, and the water is sprayed out from the spray head 5 by the operation of a water pump, thereby achieving spray curing on the construction site and reducing the probability of dust being stirred up.

[0023] Please see Figure 2As shown, the filtration mechanism 3 includes a filter box 31, which is fixedly connected to the outer surface of the water storage tank 2, and the inner cavity of the filter box 31 and the water storage tank 2 are connected. A connecting pipe 32 is fixedly connected to the end of the filter box 31 away from the water storage tank 2. A cover 33 is engaged in the inner cavity of the connecting pipe 32. A filter screen 34 is slidably connected to the inner cavity of the filter box 31. A slide rod 35 is fixedly installed on the outer surface of the filter screen 34, and a spring 36 is sleeved on the outer surface of the slide rod 35. A limit block 37 is fixedly installed on the inner wall of the filter box 31. The spring 36 is located between the filter screen 34 and the limit block 37. The slide rod 35 and the limit block 37 are slidably connected. There are two limit blocks 37 on one side of the inner wall of the filter box 31, and the filter screen 34 is located in the middle of the two limit blocks 37. A water pump is installed in the inner cavity of the water storage tank 2. The spray head 5 consists of a spray head and a conduit. The conduit away from the spray head is sleeved with the water pump. The conduit is slidably connected to the water storage tank 2. The conduit part is located... Inside the water storage tank 2, when water enters the inner cavity of the water storage tank 2 from the filter mechanism 3 for spraying and storage, the cover 33 is removed from the inner cavity of the connecting pipe 32, and water is poured from the connecting pipe 32 into the filter box 31. The filter screen 34 is used to filter the water source. By flexibly connecting the filter screen 34 to the inner cavity of the filter box 31, dust or impurities are prevented from adhering to the outer surface of the filter screen 34. When water passes through the filter screen 34, it generates a squeezing force on the filter screen 34, causing the filter screen 34 to slide in the inner cavity of the filter box 31. This causes the slide rod 35 to slide in the inner cavity of the limiting block 37 and squeeze the spring 36, thereby causing the filter screen 34 to shake in the inner cavity of the filter box 31. This prevents dust and impurities from adhering to the outer surface of the filter screen 34, improves the filtration effect of the filter screen 34, and at the same time prevents dust and impurities from entering the inner cavity of the water storage tank 2, prevents the spray head 5 from becoming clogged during spraying, and improves the uniformity of spraying.

[0024] Please see Figure 3 and Figure 4As shown, the support mechanism 6 includes a connecting plate 61. A storage rod 62 is rotatably connected to the inner cavity of the connecting plate 61. A lifting rod 63 is slidably connected to the inner cavity of the storage rod 62. A connecting frame 64 is fixedly installed at the top of the lifting rod 63. A motor 65 is slidably connected to the inner cavity of the connecting frame 64. The motor 65 is provided on the outer surface of the connecting frame 64. A gear frame 66 is slidably connected to the inner cavity of the connecting frame 64. A gear 67 is provided in the middle part of the connecting frame 64. Slider blocks 68 are fixedly connected to both ends of the gear frame 66. A limit seat 69 is rotatably connected to the top of the slider 68. The top of the limit seat 69 is connected to a limit device via a thread. Position rod 610, motor 65 output end and gear 67 are sleeved, gear 67 is half hollowed out, gear frame 66 inner wall is provided with tooth blocks, the tooth blocks and gear 67 mesh, slider 68 and connecting frame 64 are slidably connected, storage rod 62 and connecting plate 61 have a certain friction, lifting rod 63 and storage rod 62 have a certain friction, limit seat 69 and slider 68 have a certain friction. The friction facilitates the stability of the component connection, so that each component can be adjusted under the action of external force. When spraying, the spray head 5 is pulled out part of the inner cavity of the water storage tank 2 so that the spray head 5 sprays The spray head is held in the inner cavity of the limiting seat 69, and the spray head is fixed by the limiting rod 610. Two spray heads 5 can be fixed to the two limiting seats 69 respectively, with opposite spray directions, allowing simultaneous spraying of both sides of the maintenance vehicle body 1. The friction facilitates adjustment of the height and angle of the limiting seat 69. External force rotates the storage rod 62 on the connecting plate 61, changing the angle of the connecting frame 64, allowing for angle adjustment as needed. External force stretches the lifting rod 63 within the inner cavity of the storage rod 62, changing the height of the connecting frame 64, facilitating adjustment according to requirements. The height can be adjusted as needed. The limit seat 69 rotates in the inner cavity of the slider 68, which adjusts the angle of the nozzle. Thus, the height and angle of the spray can be adjusted according to actual needs and spray range. The operation of the motor 65 drives the gear 67 to rotate. The rotation of the gear 67 drives the gear frame 66 to move back and forth in the inner cavity of the connecting frame 64. In terms of spray coverage, the reciprocating linear movement allows the nozzle to perform more detailed scanning spraying in a fixed area, avoiding spray gaps caused by the overall movement of the maintenance vehicle body 1, ensuring that every part of the working surface is evenly covered, and greatly improving the comprehensiveness of the spraying.

[0025] In summary, during spray maintenance, the water tank 2 stores the water needed for spraying, the filter mechanism 3 filters the water stored in the water tank 2, and the cable wound on the bobbin 4 facilitates external power supply to the main body 1 of the maintenance vehicle. The spray head 5 is clamped above the support mechanism 6, and the water pump drives the water to spray out from the spray head 5, thereby achieving spray maintenance on the construction site and reducing the probability of dust being stirred up. By flexibly connecting the filter screen 34 to the inner cavity of the filter box 31, dust or impurities are prevented from adhering to the outer surface of the filter screen 34. When water passes through the filter screen 34, it exerts a squeezing force on the filter screen 34, causing the filter screen 34 to slide in the inner cavity of the filter box 31. This causes the slide rod 35 to slide in the inner cavity of the limit block 37 and squeeze the spring 36, thereby... This causes the filter screen 34 to vibrate within the filter box 31, preventing dust and impurities from adhering to its outer surface and improving its filtration efficiency. External force rotates the receiving rod 62 on the connecting plate 61, changing the angle of the connecting frame 64 for easy adjustment. External force stretches the lifting rod 63 within the receiving rod 62, changing the height of the connecting frame 64 for easy height adjustment. The limit seat 69 rotates within the slider 68, adjusting the nozzle angle. This allows for adjustment of the spray height and angle according to actual needs and spray range. Furthermore, the motor 65 drives the nozzle to perform more detailed scanning spraying within a fixed area, greatly enhancing the comprehensiveness of the spray.
