Description
Technical Field
[0001] This utility model relates to the field of hydropower engineering construction technology, specifically a mobile maintenance platform for hydropower engineering. Background Technology
[0002] In the field of hydropower engineering construction, maintenance platforms are key equipment to ensure the smooth operation of equipment maintenance and repair work. Currently, the maintenance platforms commonly found in the market for hydropower engineering have many problems that need to be optimized in practical applications. Some traditional maintenance platforms cannot be moved easily, and most of them require staff to carry or transport the equipment. In the complex working environment of hydropower projects, movement is difficult, making it hard to quickly reach the maintenance location, which greatly affects work efficiency.
[0003] In terms of height adjustment, existing platforms mostly adopt a single adjustment method, which either has a limited adjustment range or insufficient adjustment accuracy. This cannot meet the diverse needs of different hydropower equipment for working height during maintenance. Maintenance personnel often need to move the platform frequently due to unsuitable height, which not only increases the workload but also reduces the convenience and accuracy of maintenance operations.
[0004] Existing platforms generally lack dedicated tool storage space, and the storage of maintenance tools and parts is disorganized, which not only easily leads to tool loss, but also affects maintenance efficiency to some extent.

A connecting frame is slidably connected to the inner side of the mounting frame, and a limit shaft is threadedly connected inside the connecting frame. Storage boxes are fixedly connected to the left and right sides of the connecting frame.
[0017] Preferably, the bottom of the connecting frame is in contact with the top of the guardrail, and the limiting shaft passes through the inside of the mounting frame, so as to ensure the stability between the connecting frame and the mounting base through the limiting shaft.

[0023] 2. This mobile maintenance platform for hydropower projects, through its fixed mechanism, allows the platform to be moved to a designated position during hydropower construction. The second hydraulic cylinder then drives the fixed platform to descend, working in conjunction with a limit frame to secure it and bring it into contact with the ground. This also keeps the casters away from the ground, allowing the platform to be quickly fixed upon reaching the designated position. This ensures the platform's stability during maintenance and prevents the movement of the casters from affecting stability. Two sets of support platforms, second hydraulic cylinders, limit frames, and fixed platforms are provided to further improve balance and stability. Attached Figure Description

[0035] This utility model provides the following technical solution:
[0036] Example 1
[0037] Please see Figure 1-7 This utility model provides a technical solution: a mobile maintenance platform for hydropower projects, including casters 1, an adjustment mechanism 2 on the top of the casters 1, and fixing mechanisms 3 on the front and rear sides of the adjustment mechanism 2.
[0038] The adjustment mechanism 2 includes an adjustment component 21 and a storage component 22. The adjustment component 21 is located on top of the caster wheel 1, and the storage component 22 is located on top of the adjustment component 21.
[0039] The adjustment assembly 21 includes a support platform 211, which is fixedly connected to the top of the caster wheel 1.

The support frame 2192 is slidably connected inside the fixed frame 218. A platform 219 is fixedly connected to the top of the support frame 2192. A guardrail 2194 is fixedly connected to the top of the platform 219. A protective door 2195 is slidably connected inside the guardrail 2194. A ladder 216 is fixedly connected to the right side of the platform 219.
[0040] A protective frame 212 is fixedly connected to the top of the support platform 211. The protective frame 212 is located around the first hydraulic cylinder 213, so that the first hydraulic cylinder 213 can be protected through the protective frame 212.
[0041] The front and rear sides of the mobile platform 215 are fixedly connected with the first connecting arm 217. The first connecting arm 217 is slidably connected inside the support frame 214, so as to ensure the stability of the movement of the mobile platform 215 through the first connecting arm 217.
[0042] The top of the threaded rod 2191 is rotatably connected to the top of the fixed frame 218. The bottom of the platform 219 is fixedly connected to the front and rear sides of the platform. The second connecting arm 2193 is slidably connected to the inside of the support frame 214, so as to facilitate the movement of the load-bearing frame 2192 by the threaded rod 2191.
[0043] The protective door 2195 is located to the right of the guardrail 2194, and the bottom of the protective door 2195 is inserted into the top of the platform 219, so that the top of the platform 219 can be protected on all four sides through the protective door 2195.
[0044] Please see Figure 1-7 The present invention provides a technical solution: the storage component 22 includes a mounting frame 221, the mounting frame 221 is fixedly connected to the top left side of the guardrail 2194, a connecting frame 223 is slidably connected to the inner side of the mounting frame 221, a limit shaft 222 is threadedly connected inside the connecting frame 223, and storage boxes 224 are fixedly connected to the left and right sides of the connecting frame 223.
[0045] The bottom of the connecting frame 223 is in contact with the top of the guardrail 2194, and the limiting shaft 222 passes through the inside of the mounting frame 221, which facilitates the stability between the connecting frame 223 and the mounting base through the limiting shaft 222. There are two sets of mounting frame 221 and limiting shaft 222, which are symmetrically distributed on the front and rear sides of the connecting frame 223. By setting two sets, the stability of the connecting frame 223 can be further guaranteed, and the installation and disassembly can be facilitated.
[0046] Example 2
[0047] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a support platform 31, which is fixedly connected to the front side of the load-bearing platform 211. A second hydraulic cylinder 32 is fixedly connected to the top of the support platform 31, and a fixing platform 34 is fixedly connected to the bottom of the second hydraulic cylinder 32. A limit frame 33 is fixedly connected to the top of the fixing platform 34, and the limit frame 33 is slidably connected to the inside of the support platform 31.
[0048] The support platform 31, the second hydraulic cylinder 32, the limit frame 33 and the fixed platform 34 are provided in two sets and are symmetrically distributed on the front and rear sides of the load-bearing platform 211. This arrangement of two sets improves stability and balance when fixing the load-bearing platform 211.
[0049] In actual operation, when this device is used during hydropower construction, the casters 1 enable the maintenance platform to move freely in the complex working environment of hydropower projects, quickly reach the maintenance location, and greatly improve work efficiency. When moving to the designated position, the casters 1 need to be in a flat position. The second hydraulic cylinder 32 drives the fixed platform 34 to descend, and with the help of the limit frame 33, the fixed platform 34 contacts the ground, lifts the casters 1, and moves the casters 1 away from the ground. The platform can be quickly fixed after reaching the designated position to ensure the stability of the platform during maintenance and avoid the movement of the casters 1 affecting the stability during maintenance. The support platform 31, the second hydraulic cylinder 32, the limit frame 33 and the fixed platform 34 are provided in two sets to further improve balance and stability.
[0050] Workers climb to the top of platform 219 using ladder 216 and slide the protective door 2195 inside the guardrail 2194 with its bottom inserted into the top of platform 219 to ensure the sealing of the top of platform 219. At the same time, the connecting frame 223 is slidably connected to the mounting frame 221 and fixed between the connecting frame 223 and the mounting frame 221 by the limiting shaft 222 to ensure the stability of the storage box 224. The two sets of symmetrically distributed mounting frames 221 and limiting shafts 222 can firmly fix the connecting frame 223, so that the storage boxes 224 on the left and right sides of the connecting frame 223 can stably store maintenance tools and parts, improving maintenance efficiency.
[0051] When height adjustment is required during maintenance, the first hydraulic cylinder 213 can lift the entire moving platform 215 to initially adjust the height of the platform 219. When the required adjustment height is too high, to prevent instability caused by excessive adjustment of the first hydraulic cylinder 213, the servo motor 2196 drives the threaded rod 2191 to rotate, causing the load-bearing frame 2192 to slide up and down along the fixed frame 218, further finely adjusting the height of the platform 219. This dual adjustment mechanism can meet the diverse needs of different water and electrical equipment for working height during maintenance, reduce the frequent movement of the platform due to unsuitable height, and improve the convenience and accuracy of maintenance operations.
[0052] The guardrail 2194 and the protective door 2195 on the top of the platform 219 form a closed safety protection space, which effectively prevents maintenance personnel from falling accidentally. The mobile platform 215 and the platform 219 are slidably connected to the support frame 214 through the first connecting arm 217 and the second connecting arm 2193, which enhances the stability of the overall platform structure and keeps the platform balanced during lifting and carrying.
[0053] In this application, two first hydraulic cylinders 213, two second hydraulic cylinders 32, and a servo motor 2196 need to be connected to the same PLC controller to ensure the coordinated operation of the equipment. In addition, when carrying out water and electricity engineering construction, multiple people work together, so one person can perform specific control to ensure the safety of construction. The PLC controller is existing technology, and those skilled in the art are well aware of the specific operating steps and methods of this controller. This application will not describe it in detail.
[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
