Description

Technical Field

[0001] This utility model relates to the field of navigation lock hydraulic engineering technology, and in particular to a reinforcement structure for navigation lock hydraulic engineering. Background Technology

[0002] With the rapid growth in inland waterway shipping demand and the accelerating trend towards larger ships, traditional navigation lock hydraulic structures are facing severe challenges. Early navigation locks, due to their lower design standards and limited material performance, have long been subjected to the effects of high water level differences, high-frequency opening and closing, and complex hydrogeological conditions, leading to increasingly prominent problems such as structural fatigue, concrete carbonization, and steel corrosion. At the same time, frequent extreme weather events, such as floods and siltation, have further exacerbated the aging and damage of the lock structure, threatening navigation safety. Against this backdrop, it is necessary to develop a new type of reinforcement structure.

[0003] Traditional navigation lock hydraulic structure reinforcement devices have insufficient adjustment capabilities, making it difficult to adjust the support position and adapt to the reinforcement needs of different working conditions. They have poor versatility and adaptability, and are prone to affecting the stability of reinforcement due to improper support position. At the same time, disassembly and maintenance are cumbersome, requiring the use of various external tools. The disassembly and assembly process is complicated and time-consuming, which not only increases the cost of labor and tools, but also causes long-term interruption of navigation lock operation, disrupting the continuity of reinforcement work. It is difficult to quickly complete the replacement and maintenance of contact parts, thus affecting the normal use and safety of navigation lock hydraulic structures. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a reinforcement structure for a navigation lock hydraulic structure.

[0005] This utility model is achieved using the following technical solution: a reinforcement structure for a navigation lock hydraulic structure, comprising a support rod, a limiting plate fixedly connected inside the support rod, a moving groove provided inside the support rod, and a fixing plate fixedly connected inside the support rod, further comprising:

[0006] A telescopic mechanism, comprising a threaded rod rotatably connected inside a fixed plate, wherein a movable block is threadedly connected to the outside of the threaded rod;

[0007] The replacement mechanism includes a connecting block fixedly connected to the top of the movable block, an installation block is provided inside the connecting block, and a connecting plate is fixedly connected to the top of the installation block.

[0008] As a further improvement to the above solution, a rotating rod is rotatably connected inside the support rod, a rotating disk is fixedly connected to the outside of the rotating rod, a first bevel gear is fixedly connected to the end of the rotating rod away from the rotating disk, and a second bevel gear is fixedly connected to the outside of the threaded rod.

[0009] The above technical solution provides a carrier for manual operation force input for the telescopic mechanism; the first bevel gear and the second bevel gear form a power steering transmission path, so that the rotation of the rotating disk can be transmitted to the threaded rod, providing the power prerequisite for precise adjustment of the support position and ensuring the initial transmission feasibility of the telescopic mechanism.

[0010] As a further improvement to the above scheme, the second bevel gear meshes with the first bevel gear, the end of the threaded rod away from the fixed plate is rotatably connected to the inside of the limiting plate, and the moving block is slidably connected to the inside of the moving groove.

[0011] Through the above technical solution, the rotational connection between the threaded rod and the fixed plate and the limiting plate ensures smooth rotation, and the sliding cooperation between the moving block and the moving groove ensures precise positioning trajectory, guaranteeing the smooth and accurate synchronous movement of the replacement mechanism, improving the accuracy of support position adjustment, and helping to adapt to reinforcement needs under different working conditions.

[0012] As a further improvement to the above solution, the connecting block has a connecting groove inside, the mounting block is inserted into the connecting groove, and the mounting block has a limiting groove inside.

[0013] The above technical solution enables rapid positioning and docking of the connecting plate and the connecting block; the limiting groove provides an adaptive structure for the insertion block to engage, ensuring stable assembly of the mounting block, and also provides an unlocking basis for subsequent disassembly, laying the foundation for convenient maintenance of the replacement mechanism.

[0014] As a further improvement to the above solution, a push plate is slidably connected inside the connecting block, an inclined connecting rod is fixedly connected to the back of the push plate, and a first return spring is fixedly connected to the back of the inclined connecting rod.

[0015] Through the above technical solution, the push plate realizes tool-free triggering of disassembly and assembly; the inclined connecting rod provides a power transmission adaptation form, and the first reset spring ensures that the component automatically rebounds and resets after triggering, thus establishing the triggering and reset basis for the disassembly and assembly of the replacement mechanism, initially realizing convenient operation and simplifying the maintenance process.

[0016] As a further improvement to the above solution, the first reset spring is fixedly connected between the inclined connecting rod and the connecting block, and an insert block is slidably connected inside the connecting block, the insert block being inserted into the limiting groove.

[0017] Through the above technical solutions, the first reset spring is fixed to ensure stable rebound, the insertion block and the limit groove are inserted to ensure the installation block is firmly fixed and to prevent the connecting plate from loosening; the sliding connection of the insertion block provides feasibility for disassembly, improves the structural logic of tool-free disassembly and assembly, and ensures smooth maintenance.

[0018] As a further improvement to the above solution, an inclined transmission block is fixedly connected inside the insert block, and a second return spring is fixedly connected outside the insert block, with the second return spring fixedly connected between the insert block and the connecting block.

[0019] Through the above technical solution, the inclined plane transmission block and the inclined plane connecting rod cooperate to achieve efficient conversion of thrust into insertion block contraction force; the second reset spring ensures that the insertion block automatically rebounds and engages, perfects the tool-free disassembly and assembly closed loop, ensures convenient replacement of the connecting plate, shortens maintenance time, reduces costs, and ensures the continuity of reinforcement.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model utilizes a telescopic mechanism. The operator rotates a rotating disc, causing a rotating rod to rotate synchronously. This engages a first bevel gear with a second bevel gear outside the threaded rod, driving the threaded rod to rotate stably between a fixed plate and a limiting plate. This, in turn, causes a moving block to move linearly along the threaded rod's axial direction under the limiting position of the moving slot. Ultimately, this drives the entire replacement mechanism to move synchronously, achieving precise adjustment of the reinforcement structure's support height or horizontal position. This adapts to the reinforcement needs of navigation lock hydraulic structures under different working conditions, improving the versatility and adaptability of the reinforcement structure and ensuring stable and reliable support and protection for navigation lock hydraulic structures under various working conditions.

[0022] This utility model, through the operation of the replacement mechanism, allows pressing the push plate to drive the inclined connecting rod to squeeze the first return spring, and through the inclined contact with the inclined transmission block, to drive the insert block to retract. Releasing or pushing the push plate allows the insert block to engage or disengage from the limiting groove with the help of the rebound force of the first and second return springs, thus enabling rapid disassembly and assembly without external tools. This facilitates convenient replacement and maintenance of contact components such as the connecting plate, greatly simplifies the maintenance and replacement process, effectively shortens maintenance time, reduces labor and tool input costs, and ensures the continuity of the navigation lock hydraulic structure reinforcement work, reducing the impact of navigation lock operation interruption caused by maintenance.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 The reinforcement structure of a navigation lock hydraulic structure according to this embodiment includes a support rod 1, a limit plate 11 fixedly connected inside the support rod 1, a moving groove 12 opened inside the support rod 1, and a fixing plate 13 fixedly connected inside the support rod 1. It also includes:

[0033] Telescopic mechanism 2 includes a threaded rod 204 rotatably connected inside the fixed plate 13, and a moving block 206 is threadedly connected to the outside of the threaded rod 204.

[0034] Replacement mechanism 3 includes a connecting block 301 fixedly connected to the top of the moving block 206, an installation block 303 is provided inside the connecting block 301, and a connecting plate 305 is fixedly connected to the top of the installation block 303.

[0035] The support rod 1 is internally rotatably connected to a rotating rod 201, and externally fixedly connected to a rotating disk 202. The end of the rotating rod 201 away from the rotating disk 202 is fixedly connected to a first bevel gear 203, and externally fixedly connected to a threaded rod 204 is a second bevel gear 205.

[0036] The second bevel gear 205 meshes with the first bevel gear 203, the end of the threaded rod 204 away from the fixed plate 13 is rotatably connected to the inside of the limiting plate 11, and the moving block 206 is slidably connected to the inside of the moving groove 12.

[0037] Rotating the rotating disk 202 drives the rotating rod 201 to rotate, thereby driving the first bevel gear 203 to rotate as well. Through meshing with the second bevel gear 205, the power is transmitted to the threaded rod 204. When the threaded rod 204 rotates, the moving block 206 moves linearly along the axial direction of the threaded rod 204, thereby driving the replacement mechanism 3, which is fixedly connected to the top of the moving block 206, to move synchronously as a whole, so as to adjust the height or horizontal position of the reinforcement structure support.

[0038] The connecting block 301 has a connecting groove 302 inside, and the mounting block 303 is inserted into the connecting groove 302. The mounting block 303 has a limiting groove 304 inside.

[0039] A push plate 306 is slidably connected inside the connecting block 301. An inclined connecting rod 307 is fixedly connected to the back of the push plate 306. A first return spring 308 is fixedly connected to the back of the inclined connecting rod 307.

[0040] The first reset spring 308 is fixedly connected between the inclined connecting rod 307 and the connecting block 301. The connecting block 301 has a sliding connection of the insert 309, which is inserted into the limiting groove 304.

[0041] An inclined transmission block 3010 is fixedly connected inside the insert block 309, and a second return spring 3011 is fixedly connected outside the insert block 309. The second return spring 3011 is fixedly connected between the insert block 309 and the connecting block 301.

[0042] During installation, first press the push plate 306, causing the push plate 306 to drive the inclined connecting rod 307 to press the first return spring 308. At the same time, the inclined connecting rod 307 contacts the inclined part of the inclined transmission block 3010, causing the insert block 309 to retract inward and press the second return spring 3011. At this time, the mounting block 303 can be inserted into the connecting groove 302. After insertion, release the push plate 306. At this time, the push plate 306 and the inclined connecting rod 307 will rebound under the action of the first return spring 308. At the same time, the insert block 309 will rebound under the action of the second return spring 3011 and insert into the limiting groove 304 to complete the fixation.

[0043] The implementation principle of the reinforcement structure of a navigation lock hydraulic structure in this application embodiment is as follows: During the specific installation process, the operator selects a suitable position at the bottom of the support rod 1 as the jack support point. The jacks work together to lift the device, and the lifting height of the jacks is adjusted synchronously to keep the device horizontal and accurately align it with the preset installation position of the navigation lock hydraulic structure. After the position is correctly calibrated, the device is initially fixed, and the jacks are removed. When it is necessary to adjust the support position of the reinforcement structure to adapt to the reinforcement requirements of the navigation lock hydraulic structure under different working conditions, the operator uses the telescopic mechanism 2 to achieve precise adjustment of the overall support position. In the specific operation process, the operator rotates the rotating disk 202, driving the device to be fixed to the rotating disk 202. The rotating rod 201 connected to the fixed point rotates synchronously inside the support rod 1. The first bevel gear 203 at the end of the rotating rod 201 away from the rotating disk 202 rotates accordingly. Since the first bevel gear 203 meshes with the second bevel gear 205 outside the threaded rod 204, the power is transmitted to the threaded rod 204, so that the threaded rod 204 rotates stably between the fixed plate 13 and the limiting plate 11. When the threaded rod 204 rotates, the moving block 206 connected to its external thread moves linearly along the axial direction of the threaded rod 204 under the limiting action of the moving groove 12 inside the support rod 1. This drives the replacement mechanism 3, which is fixedly connected to the top of the moving block 206, to move synchronously as a whole, thereby realizing the adjustment of the height or horizontal position of the reinforcement structure support.

[0044] When it is necessary to replace or maintain components such as the connecting plate 305 that directly contact the hydraulic structure of the navigation lock, the replacement mechanism 3 can achieve quick disassembly and assembly. During disassembly, the push plate 306 is pushed into the connecting block 301. The push plate 306 drives the inclined connecting rod 307 to move synchronously. The first return spring 308 is compressed. The inclined surface of the inclined connecting rod 307 contacts and presses against the inclined transmission block 3010 inside the insert block 309, pushing the insert block 309 to move away from the limiting groove 304 until the insert block 309 is completely separated from the limiting groove 304. At this time, the mounting block 303 can be removed from the connecting groove 302, completing the component disassembly. This replacement mechanism 3 can achieve quick disassembly and assembly of components without the aid of external tools, which greatly simplifies the maintenance and replacement process, shortens the maintenance time, and reduces the maintenance cost.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
