Description

Technical Field

[0001] This application relates to the field of turbine assembly technology, and in particular to a support platform for stator base welding and positioning rib adjustment. Background Technology

[0002] In hydroelectric standing turbine generator units, during the assembly and welding of the generator stator base and the adjustment of positioning ribs, construction workers often directly use on-site scaffolding materials to erect simple platforms. Scaffolding is a working platform erected to ensure the smooth progress of each construction process. Scaffolding can be classified according to its location as external scaffolding and internal scaffolding; according to materials as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] However, traditional scaffolding needs to be erected from bottom to top. Only when the erected platform reaches the position where the generator stator base needs to be assembled and welded, and the positioning ribs need to be adjusted, can the operators carry out the stator base welding and positioning rib adjustment work. As a result, the non-working area is occupied by the scaffolding, so traditional scaffolding has the problem of occupying too much space. Utility Model Content

[0034] Example 1:

[0035] See Figure 1 , Figure 2 , Figure 4 and Figure 5 A support platform for stator frame welding and positioning rib adjustment includes a stator frame ring plate 7. The support platform for stator frame welding and positioning rib adjustment further includes:

[0036] The base 1 has a clamping structure 2 at one end and a sleeve 3 at the other end. A protective railing 4 is fitted inside the sleeve 3. The protective railing 4 has pin holes 5 or inverted U-shaped pins 6 on both sides.

[0037] Among them, the guardrail 4 has an arc that matches the stator frame ring plate 7, and adjacent guardrails 4 are connected by pins. The base 1 is fixed to the stator frame ring plate 7 by a clamping structure 2.

[0038] Specifically, the sleeve 3 is welded to one end of the base 1, and the sleeve 3 and the base 1 are perpendicular to each other. The sleeve 3 can be a groove structure with a closed bottom and an open top, or a through hole structure with open top and bottom. When it is a groove structure, the bottom of the guardrail 4 is inserted into the sleeve 3 through the upper opening to realize the installation of the guardrail 4. When it is a through hole structure, the bottom of the guardrail 4 and the side wall of the sleeve 3 are provided with holes that allow the limiting post 17 to pass through. The limiting post 17 is provided with holes that allow the L-shaped pin 18 to pass through. After the bottom of the guardrail 4 is inserted into the sleeve 3 through the upper opening, the positions of the bottom of the guardrail 4 and the holes on the side wall of the sleeve 3 are aligned. Then the limiting post 17 is inserted into the holes on the guardrail 4 and the sleeve 3, and the L-shaped pin 18 is inserted into the hole on the limiting post 17 to complete the installation of the guardrail 4.

[0039] The guardrail 4 has pin holes 5 or inverted U-shaped pins 6 on both sides, such as... Figure 1 As shown in the figure, the connection structure of the three guardrails 4 is illustrated. When the leftmost guardrail 4 has pin holes 5 on both sides, the middle guardrail 4 has inverted U-shaped pins 6 on both sides, allowing the leftmost guardrail 4 and the middle guardrail 4 to be connected together by pins. The rightmost guardrail 4 has pin holes 5 on both sides to facilitate the connection between the middle guardrail 4 and the rightmost guardrail 4 by pins. Figure 2 As shown, several guardrails 4 are connected together by pins to form a support structure for stator base welding and positioning rib adjustment;

[0040] When welding the stator base and adjusting the positioning ribs, several bases 1 are arranged on the inner side of the stator base ring plate 7. One end of the base 1 is quickly fixed to the stator base ring plate 7 through the clamping structure 2. Then, several guardrails 4 are inserted into the sleeve 3. Adjacent guardrails 4 are connected by pins. Several guardrails 4 are connected together to form a support for welding the stator base and adjusting the positioning ribs. The operator stands on the base 1 to perform the welding of the stator base and adjustment of the positioning ribs. At the same time, the safety is ensured by the protection of the guardrails 4.

[0041] In this embodiment, the base 1 and the protective railing 4 are fixed at the positions where the generator stator frame is to be assembled and welded and the positioning ribs are to be adjusted, so as to provide a support platform to realize the stator frame welding and positioning rib adjustment operations. Since the support platform of this application does not occupy the space of non-working areas, the problem of excessive space occupation can be avoided.

[0042] Meanwhile, all components of this application are prefabricated in the factory, transported to the site for rapid assembly, which is quick and convenient, flexible in movement, and firmly and reliably fixed, effectively improving construction efficiency while ensuring on-site construction safety. When installing stator bases and positioning ribs for other units, they can also be moved directly to other locations for rapid installation, allowing for multiple reuses.

[0043] In addition, when the sleeve 3 has a through hole structure, bolts and nuts can be used to install the guardrail 4 on the base 1; in addition to being connected by pins, adjacent guardrails 4 can also be connected by snap-fit ​​to achieve quick assembly.

[0044] See Figure 3 , Figure 4 and Figure 5 Further and optionally, the base 1 includes:

[0045] The first support rod 9 and the second support rod 10 are spaced apart. One end of the first support rod 9 and the second support rod 10 is a clamping structure 2, and the other end is fixedly connected to the sleeve 3. The first support rod 9 and the second support rod 10 are provided with support plates 11.

[0046] The support plate 11 is fixed to the first support rod 9 and the second support rod 10 by at least one pair of hooks 12.

[0047] Specifically, the first support rod 9 and the second support rod 10 are quickly fixed to the stator base ring plate 7 through the clamping structure 2. The distance between the first support rod 9 and the second support rod 10 is adjusted to meet the size of the support plate 11. Then, the support plate 11 is placed on the upper end face of the first support rod 9 and the second support rod 10. The two sides of the support plate 11 are fixed to the first support rod 9 and the second support rod 10 respectively using the hooks 12, thereby completing the installation of the support plate 11. The sleeve 3 includes two sleeves, which are respectively welded to the ends of the first support rod 9 and the second support rod 10 away from the clamping structure 2.

[0048] In this embodiment, in order to ensure the stable installation of the support plate 11, two pairs of hooks 12 are used to fix it to prevent the support plate 11 from slipping. The support plate 11 is used to support the operator and his / her work tools and to prevent the operator from falling from the gap between the first support rod 9 and the second support rod 10, thus ensuring his / her safety.

[0049] Further and optionally, a baffle 13 is provided between the sleeves 3, and the height of the baffle 13 is the same as the height of the sleeve 3.

[0050] Specifically, the baffle 13 is fixedly connected to two sleeves 3 on both sides. The baffle 13 can be made of steel plate or wood. The height of the baffle 13 is the same as the height of the sleeves 3, so that the baffle 13 can be used as a kickboard and has a certain protective effect on the workers.

[0051] Further and optionally, the guardrail 4 includes:

[0052] The first column 14 and the second column 15 are fitted into the sleeve 3, and the pin hole 5 or the inverted U-shaped pin 6 is provided on the side wall of the first column 14 and the second column 15.

[0053] Specifically, the bottoms of the first column 14 and the second column 15 are inserted into the sleeve 3 and fixed by the limiting column 17 and the L-shaped pin 18. The side walls of the first column 14 and the second column 15 are provided with pin holes 5 or inverted U-shaped pins 6 so that multiple guardrails 4 can be connected and assembled together by pins. Compared with the traditional scaffolding disassembly and assembly, the pin connection method is simple and fast.

[0054] Further and optionally, at least one crossbar 16 is provided between the first column 14 and the second column 15.

[0055] Specifically, the two ends of the crossbar 16 are welded to the inner sidewalls of the first column 14 and the second column 15, respectively. The crossbar 16 can prevent workers from falling when they retreat, thus ensuring their personal safety. By increasing the number of crossbars 16, safety can be further improved. In this embodiment, four crossbars 16 are provided.

[0056] Further and optionally, the first support rod 9, the second support rod 10, the sleeve 3, the first column 14, the second column 15 and the crossbar 16 are all rectangular tubes.

[0057] Specifically, square and rectangular tubes have a simple structure, are lightweight, easy to disassemble, and easy to install. While ensuring load-bearing capacity, they can minimize the weight of the device, making disassembly, assembly, and transportation easier.

[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
