Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance technology, and in particular to a bridge steel structure anti-corrosion maintenance lifting platform. Background Technology

[0002] Bridges are structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass. Bridge maintenance is generally carried out by placing a maintenance workbench on the outside of the bridge using specific equipment, allowing maintenance personnel to perform maintenance operations on the workbench. Although there are many types of maintenance workbench, there are still some shortcomings. The steel structure of a bridge is exposed to the natural environment for a long time and is subject to corrosion from rainwater, salt spray, industrial pollutants, etc., making it prone to rust, cracks, and other defects, which seriously threaten the structural safety.

[0003] Existing bridge steel structure anti-corrosion maintenance lifting platforms rely on traditional manual climbing, suspended baskets, or scaffolding methods, which are inefficient, have limited coverage, and pose a risk of falling from heights. They can no longer meet the refined maintenance needs of modern bridges, reducing the efficiency of the equipment during use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of low efficiency, limited coverage, and risk of falling from height in the traditional manual climbing, hanging basket, or scaffolding maintenance methods in the existing technology, which can no longer meet the refined maintenance needs of modern bridges and reduce the efficiency of the equipment during use. Therefore, a bridge steel structure anti-corrosion maintenance lifting platform is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bridge steel structure anti-corrosion maintenance lifting platform, comprising a base, with movable wheels at the bottom of the base, a support plate at the top of the base, railings fixedly connected to the surface of the support plate, a lifting device on the surface of the base, the lifting device comprising an mounting block, the mounting block being fixedly connected to both sides of the base, a threaded hole on the surface of the mounting block, a limit rod being threadedly connected inside the threaded hole, a base plate being fixedly connected to the bottom of the limit rod, a limit plate being fixedly connected to the surface of the base, a lead screw being provided between the two limit plates, a threaded block being threadedly connected to the surface of the lead screw, and the lead screw being rotatably connected between the two limit plates.

[0006] Furthermore, a fixing plate is fixedly connected to both sides of the base surface near the limiting plate, and the surface of the fixing plate is provided with a movable groove.

[0007] Furthermore, a movable block is movably connected inside the movable groove, and a connecting rod is fixedly connected to one side of the movable block. The connecting rod is located on both sides of the threaded block.

[0008] Furthermore, a mounting rod is fixedly connected between the two fixed plates, and a lifting rod is movably connected to the surface of the connecting rod, with the side of the lifting rod away from the connecting rod movably connected to the surface of the mounting rod.

[0009] Furthermore, the two lifting rods are rotatably connected by the same pivot, and the two lifting rods are respectively arranged in a cross configuration.

[0010] Furthermore, a large gear is fixedly connected to one side of the lead screw, and a small gear is meshed with one side of the large gear.

[0011] Furthermore, both the large gear and the small gear are rotatably connected to the surface of the limiting plate, and a drive motor is installed inside the small gear, with the output end of the drive motor fixedly connected to the inside of the small gear.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a lifting device is installed, which can be moved to a suitable position via movable wheels. A limiting rod rotates inside the threaded hole, causing the base plate to abut against the ground to achieve a limiting effect. A drive motor drives a small gear, which in turn drives a large gear, causing the lead screw to rotate. During this rotation, the threaded block moves back and forth, simultaneously moving the connecting rod. This causes the movable block to move left and right within the movable groove, thus achieving the lifting function of the lifting rod. Simultaneously, the rotating shaft rotates, and the lifting rod rotates on the surface of the mounting rod, ensuring stable lifting of the support plate. Its function is to allow maintenance personnel to flexibly adjust the height of the lifting platform according to the different heights of the bridge steel structure, easily reaching the parts that need anti-corrosion maintenance, without the need for other auxiliary tools or the construction of temporary platforms, greatly improving the convenience and efficiency of the operation. The lifting device can precisely control the height of the lifting platform, allowing maintenance personnel to operate at the appropriate height and angle, which helps to ensure the quality of anti-corrosion maintenance. The limiting devices on both sides of the base can fix the platform when it stops moving, increasing the stability of the platform and reducing the platform shaking caused by wind, uneven ground or other external forces, allowing maintenance personnel to work with greater peace of mind.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a bridge steel structure anti-corrosion maintenance lifting platform, including a base 1, a movable wheel 2 at the bottom of the base 1, a support plate 3 at the top of the base 1, a railing 4 fixedly connected to the surface of the support plate 3, and a lifting device 5 on the surface of the base 1.

[0016] The specific setup and function of its lifting device 5 will be explained below.

[0017] In this embodiment: the lifting device 5 includes a mounting block 51, which is fixedly connected to both sides of the base 1. The surface of the mounting block 51 is provided with a threaded hole 52, and the inside of the threaded hole 52 is threadedly connected to a limit rod 53. The bottom of the limit rod 53 is fixedly connected to a base plate 54, and the surface of the base 1 is fixedly connected to a limit plate 55. A lead screw 56 is provided between the two limit plates 55, and a threaded block 510 is threadedly connected to the surface of the lead screw 56.

[0018] Specifically, fixing plates 57 are fixedly connected to both sides of the base 1 near the limiting plate 55, and the surface of the fixing plates 57 is provided with movable grooves 58.

[0019] Specifically, the movable slot 58 is internally connected to a movable block 59, and a connecting rod 511 is fixedly connected to one side of the movable block 59.

[0020] Specifically, an installation rod 512 is fixedly connected between the two fixed plates 57, and a lifting rod 513 is movably connected to the surface of the connecting rod 511. The side of the lifting rod 513 away from the connecting rod 511 is movably connected to the surface of the installation rod 512.

[0021] Specifically, the two lifting rods 513 are rotatably connected by the same pivot 514, and the lifting rods 513 are provided in two cross-shaped configurations.

[0022] Specifically, a large gear 515 is fixedly connected to one side of the lead screw 56, and a small gear 516 is meshed with one side of the large gear 515.

[0023] Specifically, both the large gear 515 and the small gear 516 are rotatably connected to the surface of the limiting plate 55. The small gear 516 has a drive motor 517 inside, and the output end of the drive motor 517 is fixedly connected to the inside of the small gear 516.

[0024] The effects achieved by the above components are as follows: by setting up the lifting device 5, the device is moved to a suitable position via the moving wheels 2. The limiting rod 53 rotates inside the threaded hole 52, causing the base plate 54 to abut against the ground to achieve the limiting effect. The drive motor 517 drives the small gear 516 to rotate, which in turn drives the large gear 515 to rotate, thereby causing the lead screw 56 to rotate. During the rotation, the threaded block 510 moves back and forth, and at the same time, the connecting rod 511 moves, causing the movable block 59 to move left and right inside the movable groove 58, thereby enabling the lifting rod 513 to achieve the lifting effect, and thus enabling the support plate 3 to achieve the stable lifting effect. This allows maintenance personnel to flexibly adjust the height of the lifting platform according to the different height positions of the bridge steel structure, increasing the flexibility of the device during the inspection process.

[0025] Working principle: By setting up the lifting device 5, the device can be moved to a suitable position via the movable wheels 2. The limiting rod 53 rotates inside the threaded hole 52, causing the base plate 54 to abut against the ground to achieve the limiting effect. The drive motor 517 drives the small gear 516 to rotate, which in turn drives the large gear 515 to rotate, thereby rotating the lead screw 56. During the rotation, the threaded block 510 moves back and forth, and at the same time, it drives the connecting rod 511 to move, thereby causing the movable block 59 to move left and right inside the movable groove 58, thus achieving the lifting effect of the lifting rod 513. At the same time as lifting, the rotating shaft 514 also rotates, and the lifting rod 513 moves on the surface of the mounting rod 512. The lifting device 5 operates so that the support plate 3 can be raised and lowered stably. This allows maintenance personnel to flexibly adjust the height of the lifting platform according to the different heights of the bridge steel structure, easily reaching the parts that need anti-corrosion maintenance without the need for other auxiliary tools or temporary platforms, greatly improving the convenience and efficiency of the operation. The lifting device 5 can precisely control the height of the lifting platform, allowing maintenance personnel to operate at the appropriate height and angle, which helps to ensure the quality of anti-corrosion maintenance. The limiting devices on both sides of the base 1 can fix the platform when it stops moving, increasing the stability of the platform and reducing the platform shaking caused by wind, uneven ground or other external forces, allowing maintenance personnel to work with greater peace of mind.
