Description

Technical Field

[0001] This application relates to the field of power station gate equipment technology, specifically to a lifting and lowering system for a hydropower station gate. Background Technology

[0002] Hydropower gates are important tools for controlling water volume. In existing technologies, the position of the gate is generally controlled by lifting equipment such as steel cables or hydraulic cylinders, with steel cables being the most common. However, in actual use, the steel cable is in a vertical position, so the lubricating oil on the surface of the steel cable will continuously flow downwards, resulting in a lack of effective lubrication on the surface of the steel cable. During the continuous release and retrieval of the steel cable, friction will inevitably occur between the steel cable and the traction equipment, and between the steel cables themselves. The lack of lubricating oil film will not only cause accelerated wear, but will also expose the inside of the steel cable, leading to corrosion and seriously affecting the service life of the steel cable. Utility Model Content

[0012] Optionally, the lubricating cotton is also provided with a ring-shaped lubrication groove, the cross-section of which is an arc-shaped structure adapted to the steel cable.

[0013] Optionally, each of the oil pipelines is equipped with a regulating valve for controlling its on / off state.

[0014] Optionally, the regulating valve includes a valve body that is fitted onto the oil delivery pipe, and the regulating valve body is threadedly connected to a compression screw for compressing the oil delivery pipe.

[0015] Optionally, each of the adjusting rods is provided with an oil collecting funnel, which is located directly below the lubricating cotton, and the outlet end of each oil collecting funnel is connected to the temporary storage box through an oil return pipe.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] This application includes a gate and a support frame. The gate is connected to the lifting drive module via a steel cable. A plurality of adjusting rods are rotatably mounted on the support frame along the vertical direction. Each adjusting rod is rotatably mounted with a lubricating roller, and each lubricating roller is covered with lubricating cotton. A locking module is also provided between the adjusting rods and the support frame. The lifting system also includes a temporary storage tank containing lubricating oil. The outlet end of the temporary storage tank is connected to an oil pump. Each adjusting rod is equipped with an oil delivery pipe, the inlet end of which is connected to the oil pump, and the outlet end of each pipe is equipped with a dripping head for delivering lubricating oil to the lubricating cotton.

[0020] During use, the position of the support frame is adjusted to ensure that the lubricating cotton and the steel cable are in close contact. At the same time, multiple lubricating rollers are controlled to clamp the steel cable from different radial directions to avoid lubrication blind spots.

[0021] At the same time, the lubricating oil is continuously delivered to the lubricating cotton through the oil pump and the dripping head. The lubricating cotton absorbs and accumulates a large amount of lubricating oil. During the process of controlling the up and down sliding of the steel cable, the lifting drive module will drive the lubricating roller to rotate, thereby switching different contact areas. At the same time, the lubricating oil in the contact area between the lubricating surface and the steel cable will be applied to the steel cable due to the squeezing action, forming an oil film on the surface of the steel cable, thereby reducing the wear of the steel cable.

[0022] Compared with the prior art, this application can always ensure effective lubrication of the steel cable, maintain a protective oil film on the surface of the steel cable, effectively delay the wear between the steel cable and the lifting drive module, and extend the service life of the steel cable.

[0035] Implementation Method 1

[0036] Reference Figures 1 to 5 This embodiment is an optional embodiment of this application, which discloses a lifting and lowering system for a hydropower station gate, including a gate 1 and a lifting drive module 2, wherein the lifting drive module 2 includes a winch or other lifting equipment, and a gate lifting assembly commonly used in the prior art is provided on the top of the gate 1, and the winch and the lifting assembly are connected by several steel cables.

[0037] The take-off and landing system also includes several support frames 3, each support frame 3 including a base and a vertically arranged slide bar, the bottom of which is connected to the base;

[0038] Furthermore, the support frame 3 is also provided with several adjusting rods 4, which are distributed at different height positions along the vertical direction. Each adjusting rod 4 includes several telescopic rods 401, and each section of the telescopic rod 401 is sequentially and coaxially slidably connected along the axis of the adjusting rod 4. A rotating ring 12 is provided on the first-stage telescopic rod 401 directly opposite the slide rod along the axis of the adjusting rod 4, and the rotating ring 12 is slidably connected to the slide rod. At the same time, a locking module is also provided between the rotating ring 12 and the slide rod. The locking module includes a locking screw and a locking groove, wherein the locking screw is threadedly connected to the rotating ring 12, and the locking groove is arranged on the slide rod along the axis of the slide rod. The locking screw is inserted into the locking groove, thereby locking the adjusting rod 4 after the height is adjusted to the correct position.

[0039] In the above structure, the adjusting rod 4 can not only slide up and down, but also rotate around the axis of the sliding rod, thereby improving the adjustability of the position of the adjusting rod 4 and meeting the clamping requirements of different steel cables.

[0040] Furthermore, each of the adjusting rods 4 has a lubricating roller 5 rotatably mounted on its free end. Along the axis of the lubricating roller 5, a first baffle 13 is integrally connected to one end of the lubricating roller 5, and a second baffle 14 is threadedly connected to the other end. The lubricating cotton 6 is preferably made of sponge. The lubricating cotton 6 has an overall ring structure. The lubricating cotton 6 is sleeved on the lubricating roller 5, and its two ends abut against the first baffle 13 and the second baffle 14, respectively.

[0041] A ring-shaped lubrication groove 15 is also provided on the outer peripheral surface of the lubricating cotton 6. The cross-section of the lubrication groove 15 is an arc-shaped structure, and the radius of the lubrication groove 15 is adapted to the steel cable.

[0042] Furthermore, the adjusting rod 4 is provided with 2-3 parts;

[0043] The first baffle 13 and the second baffle 14 can effectively prevent the lubricating cotton 6 from sliding along the axial direction of the lubricating roller 5. Combined with the arc-shaped structure of the lubrication groove 15, it can effectively ensure that the lubricating cotton 6 and the steel cable are always in effective contact, avoiding separation between the steel cable and the lubricating cotton 6, thereby ensuring lubrication quality. Moreover, its structure is simple.

[0044] In actual use, if two adjusting rods 4 are provided, the two lubrication rods are placed on both sides of the steel cable. If three adjusting rods 4 are provided, the three lubrication rollers 5 are distributed at an angle of 120° to avoid lubrication blind spots.

[0045] Furthermore, the take-off and landing system also includes a temporary storage box 7, which stores lubricating oil. An oil replenishment pipe 19 communicating with the temporary storage box 7 is provided on the side wall of the temporary storage box 7. A transparent lubrication groove 20 is also provided on the side wall of the temporary storage box 7, and a marking line 21 is provided on the lubrication groove 20.

[0046] The above technical measures can effectively monitor the amount of lubricating oil in the temporary storage tank 7 and replenish it in time when the lubricating oil is low, so as to ensure the effective operation of the entire equipment.

[0047] Furthermore, a movable frame is slidably inserted into the upper part of the temporary storage box 7, and a filter screen 18 is provided on the movable frame; an oil collecting funnel 17 is also provided on each of the adjusting rods 4, the oil collecting funnel 17 is located directly below the lubricating cotton 6, and the outlet end of each of the oil collecting funnels 17 is connected to the temporary storage box 7 through an oil return pipe, the outlet end of the oil return pipe is located above the filter screen 18;

[0048] During the process of the steel cable and the lubricating cotton 6 being squeezed together, some lubricating oil will fall in the form of droplets. The oil droplets can be collected by the oil collection funnel 17 and flowed back into the temporary storage box 7. Finally, after being filtered by the filter screen 18, it can be reused. The oil collection funnel 17 enables the reuse of lubricating oil and avoids waste. It also helps to improve the working environment.

[0049] Furthermore, the lifting system also includes an oil pump 8, and a drip head 10 is provided on each of the adjusting rods 4. The inlet end of the oil pump 8 is connected to the temporary storage box 7 through an oil pipe 9, and its outlet end is connected to the drip head 10 through an oil pipe 9. The oil outlet of the drip head 10 is directly facing the lubricating cotton 6.

[0050] The lubricating oil is dripped onto the lubricating cotton 6 in the form of droplets through the dropper head 10. Compared with the traditional spraying, this can effectively reduce the loss of lubricating oil. On the other hand, since the contact area between the steel cable and the lubricating cotton 6 is limited, the dripping method can ensure that the lubricating oil is applied to the steel cable as quickly as possible.

[0051] Furthermore, a regulating valve 16 is also provided on the oil delivery pipe 9 between the oil pump 8 and the dosing head 10. The regulating valve 16 includes a valve body 1601, which has a through hole for the oil delivery pipe 9 to pass through. A pressing screw 1602 is also threadedly connected to the valve body 1601, and the free end of the pressing screw 1602 is inserted into the through hole.

[0052] The extrusion of the oil pipe 9 by the extrusion screw 1602 can quickly adjust the flow area of ​​the oil pipe 9, thereby assisting in controlling the amount of lubricating oil delivered.

[0053] During use, the position of the support frame is adjusted to ensure that the lubricating cotton and the steel cable are in close contact. At the same time, multiple lubricating rollers are controlled to clamp the steel cable from different radial directions to avoid lubrication blind spots.

[0054] Subsequently, the lubricating oil is continuously delivered to the lubricating cotton through the oil pump and the dripping head. The lubricating cotton absorbs and accumulates a large amount of lubricating oil. During the process of controlling the up and down sliding of the steel cable, the lifting drive module drives the lubricating roller to rotate, thereby switching different contact areas. At the same time, the lubricating oil in the contact area between the lubricating surface and the steel cable will be applied to the steel cable due to the squeezing action, forming an oil film on the surface of the steel cable, thereby reducing the wear of the steel cable.

[0055] Compared with the prior art, this application can always ensure effective lubrication of the steel cable, maintain a protective oil film on the surface of the steel cable, effectively delay the wear between the steel cable and the lifting drive module, and extend the service life of the steel cable.

[0056] Secondly, the structure of this application is simple, which can effectively simplify the structure of the equipment and improve its stability and reliability.

[0057] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
