Description

Technical Field

[0001] This utility model relates to the field of electromechanical maintenance technology, and in particular to a novel maintenance device for highway electromechanical systems. Background Technology

[0002] Highway electromechanical maintenance equipment refers to specialized tools and equipment used for the regular maintenance, inspection, adjustment, and troubleshooting of various electromechanical equipment (such as monitoring equipment, toll collection systems, communication equipment, lighting equipment, and power supply and distribution equipment) on highways. Its functions are: ensuring normal equipment operation: through regular maintenance, potential equipment problems can be identified and resolved in a timely manner, ensuring that the equipment is always in good operating condition; extending equipment service life: reasonable maintenance and repair can reduce equipment wear and tear, prevent premature damage, and thus extend the equipment's service life; improving reliability and safety: during maintenance, potential safety hazards can be identified and repaired, improving equipment reliability and safety, and ensuring production safety and quality.

[0003] Conventional highway electromechanical maintenance equipment is mostly located at the rear of the vehicle to house various tools. There are many devices installed on highways, including electrical distribution boxes, light boards, streetlights, etc. When these devices are being maintained, maintenance personnel often need to climb to higher places using ladders or other means. This is inconvenient for maintenance personnel, and the climbing process is also quite dangerous, with the risk of falling and getting injured. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when existing equipment is being repaired, maintenance personnel often need to climb to a high place using ladders or other means to perform maintenance, which is inconvenient for maintenance personnel and dangerous, with the risk of falling and getting injured. Therefore, a new type of maintenance device for highway electromechanical equipment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel maintenance device for highway electromechanical systems includes a carriage. A hydraulic pump is fixedly connected to the top of the inner wall of the carriage. A bottom lifting platform is fixedly connected to the top of the telescopic end of the hydraulic pump. The bottom lifting platform is connected to a top lifting platform via a manual lifting structure. Symmetrically distributed brackets are fixedly connected to the inner wall of the carriage. A drive motor is fixedly connected to the brackets. The drive motor is connected to a fixing pin via a vehicle stabilizing structure. Rollers are fixedly connected to the bottom of the carriage in a uniformly distributed manner.

[0007] Preferably, the manual lifting structure includes evenly distributed slides, limiting blocks, folding frames, fixed shafts, center blocks, lead screws, and rotating disks. The slides are respectively arranged on both sides of the outer wall of the bottom lifting platform and the top lifting platform. The limiting blocks are slidably connected to the inner wall of the slides. The folding frames are rotatably connected to the inner wall of the bottom lifting platform and the inner wall of the top lifting platform.

[0008] Preferably, the fixed shaft is located at the middle connection of the folding frame, the central block is located at the middle end of the fixed shaft, one end of the lead screw is rotatably connected to the outer wall of the central block, and the rotating disk is fixedly connected to the other end of the lead screw.

[0009] Preferably, the folding frame is rotatably connected to the limiting circular block, the fixed shaft and the center block are symmetrically distributed, and the other end of the lead screw passes through the outer wall of the right center block and is threadedly connected.

[0010] Preferably, the vehicle stabilization structure includes symmetrically distributed gears, an outer rack, and an inner rack. The gears are rotatably connected to the bottom of the inner wall of the vehicle body, the outer rack is slidably connected to the bottom of the inner wall of the vehicle body, and the inner rack is slidably connected to the bottom of the inner wall of the vehicle body.

[0011] Preferably, the gears mesh with the outer rack and the inner rack respectively. One end of the outer rack passes through the outer wall of one side of the carriage and is slidably connected. One end of the inner rack passes through the outer wall of the other side of the carriage and is slidably connected. The fixing pin is disposed on one end of the outer rack and the inner rack outside the carriage.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In use, this utility model can not only use the hydraulic pump and manual lifting structure to raise and lower the lifting platform to a certain height, allowing people to repair equipment that is above their own height, but also use the manual rotation of the screw to raise the folding frame, allowing the lifting platform to rise even higher, so that equipment at the very top can be easily accessed. This eliminates the need to climb ladders to reach high places, making maintenance safer and preventing falls and injuries. It also makes it more convenient for maintenance personnel to raise and lower the lifting platform for maintenance.

[0014] 2. When this utility model is in use, the drive motor can drive the gear to rotate, and the gear can drive the outer rack and inner rack to unfold from the inside to the outside. Then, the fixing nail is installed on the rack. The pointed end of the fixing nail increases the friction with the ground, thereby stabilizing the carriage. At the same time, the fixing nail can prevent the device from sliding and avoid the instability of the center of gravity of the maintenance personnel above due to sliding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 A novel maintenance device for highway electromechanical systems includes a carriage 1. A hydraulic pump 2 is fixedly connected to the top of the inner wall of the carriage 1. A bottom lifting platform 3 is fixedly connected to the top of the telescopic end of the hydraulic pump 2. The bottom lifting platform 3 is connected to a top lifting platform 4 via a manual lifting structure. A symmetrically distributed bracket 5 is fixedly connected to the inner wall of the carriage 1. A drive motor 6 is fixedly connected to the bracket 5. The drive motor 6 is connected to a fixing nail 7 via a vehicle stabilizing structure. Rollers 8 are fixedly connected to the bottom of the carriage 1 in a uniformly distributed manner.

[0022] It should be noted that the hydraulic pump 2 and the drive motor 6 are existing technologies. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technologies in this field, so it will not be elaborated here.

[0023] Furthermore, the manual lifting structure includes evenly distributed slide grooves 9, limiting blocks 10, folding frames 11, fixed shafts 12, center blocks 13, lead screws 14, and rotating disks 15. The slide grooves 9 are respectively set on both sides of the outer wall of the bottom lifting platform 3 and the top lifting platform 4. The limiting blocks 10 are slidably connected to the inner wall of the slide grooves 9. The folding frames 11 are rotatably connected to the inner wall of the bottom lifting platform 3 and the inner wall of the top lifting platform 4.

[0024] The width of the limiting block 10 is greater than the width of the slide groove 9, so that one end of the folding frame 11 can slide the limiting block 10 in the slide groove 9 without easily disengaging from the slide groove 9.

[0025] Furthermore, the fixed shaft 12 is located at the middle connection of the folding frame 11, the center block 13 is located at the middle end of the fixed shaft 12, one end of the lead screw 14 is rotatably connected to the outer wall of the center block 13, and the rotating disk 15 is fixedly connected to the other end of the lead screw 14.

[0026] When the rotating disk 15 drives the lead screw 14 to rotate, the lead screw 14 can move the connection in the middle of the folding frame 11 closer to or further away, thereby enabling the top lifting platform 4 to be manually raised and lowered.

[0027] Furthermore, the folding frame 11 is rotatably connected to the limiting block 10, the fixed shaft 12 and the center block 13 are symmetrically distributed, and the other end of the lead screw 14 passes through the outer wall of the right center block 13 and is threadedly connected.

[0028] The top of the top lifting platform 4 is equipped with a guardrail to prevent maintenance personnel standing on it from falling.

[0029] Furthermore, the vehicle stabilization structure includes a symmetrically distributed gear 16, an outer rack 17, and an inner rack 18. The gear 16 is rotatably connected to the bottom of the inner wall of the carriage 1, the outer rack 17 is slidably connected to the bottom of the inner wall of the carriage 1, and the inner rack 18 is slidably connected to the bottom of the inner wall of the carriage 1.

[0030] Among them, the outer rack 17 and the inner rack 18 slide in opposite directions. The outer rack 17 and the inner rack 18 have sliding holes on one end outside the carriage 1. The fixing pin 7 is slidably connected to the sliding hole, and the bottom end of the fixing pin 7 exceeds the lowest end of the roller 8.

[0031] Furthermore, gear 16 meshes with outer rack 17 and inner rack 18 respectively. One end of outer rack 17 passes through the outer wall of one side of carriage 1 and is slidably connected. One end of inner rack 18 passes through the outer wall of the other side of carriage 1 and is slidably connected. Fixing pin 7 is set on one end of outer rack 17 and inner rack 18 outside the carriage.

[0032] The vehicle stabilization structure is achieved by starting the drive motor 6, which drives the gear 16 to rotate. The gear 16 then drives the outer rack 17 and the inner rack 18 to move in different directions. Once they are in the appropriate positions, the fixing nail 7 placed in the carriage 1 can be removed and inserted into the sliding hole.

[0033] Working principle: When using the maintenance device, the carriage 1 needs to be moved to a suitable position using rollers 8. Then, the drive motor 6 is started, which drives the gear 16 to rotate. The gear 16 drives the outer rack 17 and the inner rack 18 to move in different directions. After moving to the suitable position, the fixing nail 7 placed inside the carriage 1 can be removed and inserted into the sliding hole. On softer ground, the fixing nail 7 can be driven into the ground. Then, the maintenance personnel stand on the top lifting platform 4 and start the hydraulic pump 2. The telescopic end of the hydraulic pump 2 pushes the bottom lifting platform 3 to rise. When maintenance needs to be performed at a higher location, the device can be moved to the top lifting platform 4. The rotating disc 15 can be manually rotated by other staff. The rotating disc 15 drives the lead screw 14 to rotate, and the lead screw 14 drives the connection of the folding frame 11 to move closer together. At the same time, the folding frame 11 moves upward, thereby driving the top lifting platform 4 to a higher position. This eliminates the need to climb to a high place with a ladder, making it safer before and after maintenance and preventing easy falls and injuries. It is also more convenient for maintenance personnel to perform maintenance by rising and falling on the lifting platform. In addition, the fixing nail 7 not only stabilizes the carriage, but also prevents the device from sliding, avoiding instability of the center of gravity of the maintenance personnel above due to sliding.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
