Description

Technical Field

[0001] This utility model relates to auxiliary equipment for hydropower station maintenance, and in particular to a lifting lug for a hydropower unit maintenance platform. Background Technology

[0002] During the maintenance of hydropower units, a maintenance platform needs to be erected in the tailrace cone section to facilitate the lowering of the turbine runner during major overhauls, or to inspect components such as the runner blades and spillway cones during minor overhauls. Minor overhauls are performed annually, while major overhauls are performed every 6-8 years. Previously, the platform's lifting lugs were made of ordinary 45# steel, semi-circular, and welded to the cone section wall as mounting points. However, these lugs, directly exposed to the water flow, are easily corroded by the running water, compromising the safety of the platform erection. Furthermore, the increased hydraulic resistance results in hydraulic losses, reducing the unit's output.

[0003] Given that existing platform lugs are easily corroded by direct exposure to water flow, a platform lug that is easy to preserve is needed. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a lifting lug for a hydropower unit maintenance platform, including a support member 1. The support member 1 includes a support platform 11 and a receiving groove 14 opened inside the support platform 11. The support member 1 carries a lifting lug structure for suspension. At the same time, the support member 1 is fixed to the pipe wall of the tailrace cone section to be inspected, serving the functions of support and connection; and,

[0029] The lifting rod structure 2 includes a baffle 21, which serves to waterproof the lifting rod structure 2 when it is housed in the bearing member 1. An inclined rod 22 is set on the side of the baffle 21. The inclined rod 22 is a structure that bears the weight of the platform when the lifting lug is working. The maintenance platform is hung on the inclined rod 22.

[0030] Furthermore, multiple connecting grooves 12 are formed on the outer surface of the support platform 11. Typically, the pipe wall to be inspected is made of cast concrete. Preferably, a hollow groove of the same volume as the support platform 11 is cut into the pipe wall, and then the support platform 11 is placed in the hollow groove on the pipe wall and fixed in the hollow groove with cement. The connecting grooves 12 formed on the outer surface of the support platform 11 increase the contact surface between the support platform 11 and the cement, and also increase the roughness, which is beneficial to the stable connection between the support platform 11 and the pipe wall. The receiving groove 14 is inclined, accommodating... The end of the receiving groove 14 near the baffle 21 is higher than the end of the receiving groove 14 away from the baffle 21. The inclined groove cooperates with the inclined rod 22, and the inclined rod 22 can slide inside the inclined groove. The receiving groove 14 near the baffle 21 has a recessed groove 13, which is connected to the receiving groove 14. The bottom of the recessed groove 13 has an opening 131, and the inclined rod 22 can be stored inside the inclined groove. The baffle 21 can be embedded inside the recessed groove 13. When it is necessary to remove the baffle 21 and the inclined rod 22, the baffle 21 is pried out from the bottom of the recessed groove 13.

[0031] Furthermore, the lateral width of the groove 13 is the same as the lateral width of the baffle 21, and the length of the groove 13 is slightly greater than the length of the baffle 21. Only when the length of the groove 13 is slightly greater than the length of the baffle 21 can the baffle 21 be smoothly removed from the groove 13. The baffle 21 includes a waterproof panel 211. The bottom of the waterproof panel 211 is provided with a bottom notch 212. Preferably, the bottom notch 212 is provided at the bottom of the waterproof panel 211 to facilitate the removal of the waterproof panel 211.

[0032] Furthermore, the diagonal bar 22 includes a hanging rod 221 disposed on the side of the waterproof panel 211. The outer wall of the hanging rod 221 is provided with a hanging groove 222. When the maintenance platform is suspended, the connecting parts on the maintenance platform are suspended on the hanging groove 222.

[0033] Usage: When suspending the maintenance platform, hook the hook on the maintenance platform onto the hanging groove 222. At this time, the hook will exert a downward force on the hanging groove 222, i.e., the inclined rod 22. As a result, the inclined rod 22 tends to move downward, which will also drive the baffle 21 to move downward. Then, the baffle 21 will exert a force on the hook toward the support platform 11. The baffle 21 and the support platform 11 together clamp the hook, making the suspension more stable and safe. After the maintenance is completed and the maintenance platform is removed, push the baffle 21 and the inclined rod 22 into the support platform 11 to store the suspension rod structure 2. The suspension rod structure 2 is no longer in the water flow, which can reduce its corrosion and delay corrosion.

[0034] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the receiving groove 14 includes a horizontal groove 151 opened inside the support platform 11, a vertical groove 152 opened on the side of the horizontal groove 151, and a limiting protrusion 153 provided on the top side of the vertical groove 152.

[0035] Furthermore, the rod structure 2 also includes a crossbar 241 disposed inside the transverse groove 151. The crossbar 241 can slide within the transverse groove 151, and a slider 242 is provided at the end of the crossbar 241 away from the transverse groove 151.

[0036] Preferably, a cover plate 231 is provided on the side of the crossbar 241. The top of the cover plate 231 is connected to the inner wall of the longitudinal groove 152. The top of the cover plate 231 is rotatably connected to the top of the longitudinal groove 152. A sliding groove 232 is provided at the bottom of the cover plate 231. A slider 242 is provided inside the sliding groove 232. The slider 242 can slide inside the sliding groove 232.

[0037] Usage: When it is necessary to suspend the maintenance platform, the cover plate 231 can be rotated to pull out the crossbar 241. The slider 242 on the crossbar 241 will move away from the connection end between the cover plate 231 and the support platform 11 in the slide groove 232. When the slider 242 moves to the bottom, the cover plate 231 is opened to the maximum extent. At this time, the maintenance platform can be suspended on the crossbar 241. When the maintenance is completed, the cover plate 231 can be rotated downward to push the crossbar 241 into the cross groove 151 for storage.

[0038] Example 3, referring to Figures 1-5 This is the third embodiment of the present invention. Unlike the previous embodiment, a hanging plate 25 can be provided at the bottom and rotatably connected to the bearing member. The top of the hanging plate 25 is connected to the support platform 11 through a chain A. A storage groove 16 for storing the hanging plate 25 and the chain A is provided on the support platform.

[0039] When it is necessary to suspend the maintenance platform, simply flip out the mounting plate 25 and hang the maintenance platform on the mounting plate 25.
