Description

Technical Field

[0001] This utility model belongs to the technical field of maintenance devices, and specifically relates to the installation node of a tailwater inlet gate maintenance device. Background Technology

[0002] The draft tube of a water turbine is part of the turbine's flow passage and plays a vital role in turbine operation. For ease of installation and maintenance, an inlet valve is usually added to the conical section of the draft tube. Due to water pressure and pressure pulsation, the draft tube inlet valve is prone to fatigue cracks. Therefore, it is necessary to paint the draft tube inlet valve before installation to reduce the likelihood of cracks appearing after long-term use.

[0003] The inward-facing side of the tailwater inlet gate is easier to paint, while the outward-facing side requires the use of a scaffold. The scaffold is typically fixed to the tailwater inlet gate, and since all areas of the gate need painting, painting areas inaccessible to workers standing on the scaffold is difficult. Additionally, painting the connection between the scaffold and the tailwater inlet gate is also challenging. Utility Model Content

[0004] This utility model provides an installation node for a tailwater inlet gate maintenance device to solve the problem of low efficiency in painting the entire tailwater inlet gate area.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An installation node for a tailwater inlet gate maintenance device includes an inlet gate frame, a horizontal support, and a climbing frame. The climbing frame is fixed to the horizontal support and passes through the inlet gate frame. The horizontal support is disposed above the inlet gate frame.

[0007] The horizontal shelf passes through the center of the entrance door frame, and a slide rail is installed outside the entrance door frame. The horizontal shelf is slidably engaged with the slide rail.

[0008] Furthermore, a locking block is fixed to the side wall of the horizontal shelf that is in contact with the entrance door frame, and a locking groove is formed on the side of the slide rail away from the entrance door frame. The locking block matches the shape of the locking groove and is inserted into the locking groove.

[0009] Furthermore, the slide rail includes multiple interconnected track segments, and the side wall of each track segment near the entrance door frame is attached to and abuts against the entrance door frame.

[0010] Furthermore, one end of the track segment has a protrusion forming a bump, and the other end has a recess forming a groove. The shape of the bump matches the shape of the groove, and when two adjacent track segments are spliced ​​together, the bump is inserted into the groove.

[0011] Furthermore, the height of the slide rail is higher than the height of the entrance door frame, the two ends of the horizontal bracket overlap the slide rail, and both ends of the horizontal bracket extend out of the slide rail.

[0012] Furthermore, the entrance door frame is provided with a plurality of anchoring holes spaced in a ring, and anchoring members are installed in the anchoring holes. Each anchoring member and the slide rail are provided with a support member, one end of which abuts against the anchoring member and the other end of which abuts against the slide rail.

[0013] Furthermore, the parts of the slide rail and the cross shelf that come into contact with each other are ground and polished.

[0014] Furthermore, a limiting component is detachably provided on the slide rail, and the limiting component is provided on both sides of the cross shelf to restrict the cross shelf from rotating relative to the slide rail.

[0015] The present invention can achieve the following beneficial effects:

[0016] 1. This application reduces the difficulty of painting various areas of the entrance door frame by setting up a horizontal shelf and a climbing frame at the entrance door frame, allowing workers to stand on the climbing frame to paint the entrance door frame; a sliding rail is set outside the entrance door frame, allowing the horizontal shelf to rotate relative to the sliding rail, thereby facilitating the adjustment of the worker's operating surface and making it easier for the worker to adjust their position to achieve the painting work of various areas of the circular door frame.

[0017] 2. By setting a locking block and opening a locking groove on the side wall of the slide rail, the movement trajectory of the horizontal shelf can be restricted, and the horizontal shelf can only rotate around the slide rail. This reduces the occurrence of deviation during the movement of the horizontal shelf and ensures the safety of workers when performing painting operations on the climbing frame.

[0018] 3. Setting the slide rail to be higher than the entrance door frame not only prevents the horizontal shelf from directly contacting the entrance door frame, thus improving the painting effect on the inner side of the entrance door frame, but also reduces the friction between the horizontal shelf and the slide rail, making it easier to rotate the horizontal shelf relative to the slide rail. As a result, only two workers are needed to efficiently complete the painting work on the entrance door frame, saving labor and improving the efficiency of the painting work.

[0024] 1. Entrance door frame; 11. Anchor hole; 2. Horizontal support; 21. Locking block; 3. Climbing frame; 4. Slide rail; 41. Locking groove; 42. Track section; 421. Protrusion; 422. Groove; 5. Anchor; 6. Support; 7. Limiting component; 8. Tailwater inlet door. Detailed Implementation

[0025] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0026] like Figure 1 The diagram shows the structure at the tailwater inlet gate, including a tailwater inlet gate frame 1 and a tailwater inlet gate 8. In this application, the tailwater inlet gate frame 1 is simply referred to as the inlet gate frame 1. The tailwater inlet gate 8 is installed on the inlet gate frame 1. When painting the inlet gate frame 1, the tailwater inlet gate 8 is removed. After the painting work is completed, the tailwater inlet gate 8 is installed back onto the inlet gate frame 1.

[0027] Example 1

[0028] This application provides an installation node for a tailwater inlet gate maintenance device, referring to... Figure 2 It also includes a horizontal support frame 2 and a climbing frame 3. The climbing frame 3 is fixed to the horizontal support frame 2 and passes through the entrance door frame 1, providing a place for operators to stand and perform painting work on the outward-facing side of the entrance door frame 1. The two ends of the horizontal support frame 2 overlap the entrance door frame 1 to provide stable support for the climbing frame 3. The horizontal support frame 2 can be angle steel or other structures that can fix the climbing frame 3. When the horizontal support frame 2 is placed above the entrance door frame 1, the horizontal support frame 2 passes through the center of the entrance door frame 1.

[0029] Outside the entrance frame 1, a sliding rail 4 is also installed. The sliding rail 4 includes multiple track segments 42 that are spliced ​​together. One end of each track segment 42 protrudes outward to form a protrusion 421, and the other end is recessed inward to form a groove 422. The protrusion 421 and the groove 422 are matched in shape. When splicing two adjacent track segments 42, the protrusion 421 is inserted into the groove 422 to achieve quick assembly of the sliding rail 4.

[0030] The slide rail 4 has an inwardly recessed annular locking groove 41 on the side facing away from the entrance door frame 1. Two locking blocks 21 are fixed to the side wall of the horizontal shelf 2 that is in contact with the entrance door frame 1. These two locking blocks 21 are respectively located at both ends of the horizontal shelf 2 and slidably inserted into the locking groove 41. The locking blocks 21 guide the movement of the horizontal shelf 2, allowing it to rotate and thus adjust the painting work surface for the worker. Furthermore, the side wall of the slide rail 4 facing the entrance door frame 1 is flush with the entrance door frame 1, thus using the entrance door frame 1 to support the slide rail 4. This ensures that the locking blocks 21 stably prevent the horizontal shelf 2 from detaching from the slide rail 4, maintaining stability even when a person is standing on the climbing frame 3.

[0031] When installing the horizontal support 2 and the slide rail 4, first insert the locking blocks 21 at both ends of the horizontal support 2 into the locking slots 41 of the two track sections 42 respectively, and then fit the horizontal support 2 and the two track sections 42 onto the outside of the entrance door frame 1. After the horizontal support 2 and the two track sections 42 are installed, the other track sections 42 are assembled to finally form a circular slide rail 4.

[0032] When painting the entrance door frame 1 using the maintenance device of this application, the worker can stand on the climbing frame 3 to paint the outer side of the entrance door frame 1. After painting some areas, the worker can drive the horizontal shelf 2 to rotate, thereby adjusting the worker's operating surface and achieving painting of all areas of the entrance door frame 1 in the outward direction. When painting the inner side of the entrance door frame 1, the worker can first paint the area not covered by the horizontal shelf 2, then rotate the horizontal shelf 2 to expose the covered area, so as to achieve simultaneous painting of the inner and outer walls of the entrance door frame 1.

[0033] The maintenance device of this application can also make painting work on the inner ring wall of the entrance door frame 1 safer, reducing the possibility of workers falling from the entrance door frame 1 when painting the inner ring wall of the entrance door frame 1 while standing inside the entrance door frame 1.

[0034] Example 2

[0035] The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the height of the slide rail 4 is higher than the height of the door frame 1, so that both ends of the horizontal support 2 are attached to the slide rail 4, and both ends of the horizontal support 2 extend out of the slide rail 4, so as to achieve stable support of the horizontal support 2 for the climbing frame 3.

[0036] In addition, the parts in contact with the slide rail 4 and the cross shelf 2 are all polished to reduce the friction between the cross shelf 2 and the slide rail 4, making the cross shelf 2 easier to push and rotate relative to the slide rail 4. In embodiment 2, when painting the entrance door frame 1, only two workers are needed. One worker stands on the climbing frame 3 to paint the inner and outer walls of the entrance door frame 1, and the other worker paints the inner wall of the entrance door frame 1 and assists the other worker in pushing the cross shelf 2 to rotate. This allows the worker standing on the climbing frame 3 to complete the painting of the entire area of ​​the entrance door frame 1 without leaving the climbing frame 3.

[0037] Limiting components 7 can also be detachably installed on the slide rail 4. The limiting component 7 can be a metal elastic clip or a rubber block that can be installed on the surface of the slide rail 4. By setting the limiting components 7 on both sides of the horizontal shelf 2, the sliding of the horizontal shelf 2 relative to the slide rail 4 can be temporarily restricted, so that the horizontal shelf 2 can remain stable when the worker is painting. At the same time, when another worker needs to assist in rotating the horizontal shelf 2, the limiting component 7 can be quickly removed from the slide rail 4 and the horizontal shelf 2 can be pushed to rotate.

[0038] The entrance door frame 1 typically has multiple anchor holes 11 spaced circumferentially on its surface. Anchors 5 are installed in the anchor holes 11 to achieve a more stable connection between the entrance door frame 1 and the building structure. The anchors 5 can specifically be fixing bolts. In this embodiment, a support member 6 is also provided between each anchor 5 and the slide rail 4. One end of the support member 6 abuts against the side wall of the anchor 5, and the other end abuts against the side wall of the slide rail 4 extending beyond the entrance door frame 1. Figure 3 Only one bracing member 6 is shown. By setting the bracing member 6, the possibility of the slide rail 4 tipping over towards the door frame 1 under the force of the cross brace 2 can be reduced.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
