Description

Technical Field

[0001] This utility model relates to the field of power generation equipment, and in particular to a blade seat assembly and disassembly tool. Background Technology

[0002] The guide vane mount is one of the core components of the generator. When assembling or disassembling the guide vane mount, a base that can provide stable support is required.

[0003] However, the guide vane holders of large generators are large, and the required support base is also very large, making storage and transportation very inconvenient. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution;

[0006] A guide vane seat assembly and disassembly tool includes a ring-shaped base with pawls connected to the base;

[0007] Each of the two ends of the sub-base is provided with an outwardly extending flange, and the flange has a first bolt hole. Two adjacent sub-bases are connected by bolts through the first bolt hole.

[0008] The flange is connected to the claw.

[0009] First, this invention divides the base into four sections, making storage and transportation more convenient. Second, this invention utilizes the flanged connecting claws of the base, which, compared to designs with separate components, not only reduces production costs but also effectively improves the strength of this invention.

[0010] Preferably, the four sub-bases are a first sub-base located at the upper left, a second sub-base located at the upper right, a third sub-base located at the lower left, and a fourth sub-base located at the lower right; the first sub-base has a first flange at its upper end and a second flange at its lower end; the second sub-base has a second flange at its upper end and a second flange at its lower end; the third sub-base has a first flange at its upper end and a first flange at its lower end; the fourth sub-base has a first flange at its upper end and a second flange at its lower end; the length of the first flange is greater than the length of the second flange, and the first flange has a second bolt hole for connecting the claw; the first flanges located at the upper ends of the third sub-base and the upper ends of the fourth sub-base are connected to the claw via bolts through the second bolt holes, while the first flanges located at the upper ends of the first sub-base and the lower ends of the fourth sub-base are not connected to the claw. The position and length of the flanges in this invention have been optimized, making the flanges on the left and right sides axially symmetrical, thereby effectively balancing the force on the invention. In addition, the flanges on the top and bottom sides are rotationally symmetrical, making it convenient to rotate and move the invention using these flanges.

[0011] Preferably, the first flange has two vertically arranged first bolt holes and two vertically arranged second bolt holes, and the distance from the first bolt holes to the central axis of the base is less than the distance from the second bolt holes to the central axis of the base. Compared with a single bolt hole structure, this effectively ensures the connection strength between the two components.

[0012] Preferably, the claw includes a first claw arm extending perpendicular to the central axis of the base, and a second claw arm extending at an angle of 9°-12° to the central axis of the base; a first flange located at the upper end of the third sub-base and the upper end of the fourth base are connected to one end of the first claw arm by bolts through the second bolt holes, the other end of the first claw arm is welded to the middle of the second claw arm, and each end of the second claw arm is provided with an elliptical hole; one end of the first claw arm has a third bolt hole matching the second bolt hole, the other end of the first claw arm is welded to the middle of the second claw arm, and each end of the second claw arm is provided with an elliptical hole.

[0013] This invention optimizes the structure of the chuck, utilizing an inclined second chuck arm to more easily insert the invention into the guide vane seat. The elliptical hole at the closer end of the second chuck arm allows for bolting to the connecting bolt holes on the guide vane seat, while the bolt hole at the farther end of the second chuck arm allows for inserting a traction rope to pull and move the invention together with the guide vane seat.

[0014] It also includes a ring-shaped support ring, which is sleeved inside the base, with the outer side wall of the support ring abutting against the inner side wall of the base. This support ring increases the structural strength of the present invention.

[0015] The outer wall of the support ring is provided with an outwardly extending limiting plate, which is sandwiched between one of the first flanges and the second flange. This limiting plate restricts the relative position of the limiting plate and the base.

[0016] An extension plate is provided at the connection between the first flange and its sub-base, and a notch matching the extension plate is provided at the connection between the second flange and its sub-base. This allows the extension plate to guide the connected sub-base and, more importantly, increases the structural strength of the connection.

[0017] The thickness of the extension plate decreases as it moves further away from the sub-base, facilitating insertion into the notch. This notch can be a hole, a slot, etc., but is preferably a notch formed by an inclined cut. Attached Figure Description

[0026] Example 1

[0027] Reference Figures 1-3 To make the structure clearer, Figure 1 The right-side flange is cut open. It includes a ring-shaped base 1, on which a claw 2 is connected.

[0028] The base 1 consists of four sub-bases, each sub-base being a quarter-circle arc. Each sub-base has an outwardly extending flange at both ends, with a first bolt hole 17 on the flange. Adjacent sub-bases are connected by bolts through the first bolt holes 17. A locking claw 2 is connected to the flange. This invention divides the base 1 into four parts, making storage and transportation more convenient. Furthermore, this invention utilizes the flange of the base 1 to connect the locking claw 2, which, compared to a separate component design, not only reduces production costs but also effectively improves the strength of the invention.

[0029] The four sub-bases are: the first sub-base 11 located at the upper left, the second sub-base 12 located at the upper right, the third sub-base 13 located at the lower left, and the fourth sub-base 14 located at the lower right. The first sub-base 11 has a first flange 15 at its upper end and a second flange 16 at its lower end; the second sub-base 12 has a second flange 16 at its upper end and a second flange 16 at its lower end; the third sub-base 13 has a first flange 15 at its upper end and a first flange 16 at its lower end. The fourth sub-base 14 has a first flange 15 at its upper end and a second flange 16 at its lower end. The length of the first flange 15 is greater than the length of the second flange 16. The first flange 15 has a second bolt hole 18 for connecting the claw 2. The first flange 15 located at the upper end of the third sub-base and the upper end of the fourth base is connected to the claw 2 by bolts through the second bolt hole 18. The first flange 15 located at the upper end of the first sub-base and the lower end of the fourth sub-base is not connected to the claw 2. This utility model optimizes the position and length of the flanges, making the flanges on the left and right sides of the utility model axially symmetrical, thereby effectively balancing the force on the utility model. In addition, the flanges on the upper and lower sides are rotationally symmetrical, which facilitates the rotation and movement of the utility model using these flanges.

[0030] The first flange 15 has two vertically arranged first bolt holes 17 and two vertically arranged second bolt holes 18. The distance from the first bolt hole 17 to the central axis of the base 1 is less than the distance from the second bolt hole 18 to the central axis of the base 1. Compared with a single bolt hole structure, this effectively ensures the connection strength between the two components.

[0031] Preferably, the claw 2 includes a first claw arm 21 extending perpendicularly to the central axis of the base 1, and a second claw arm 22 extending at an angle of 9°-12° to the central axis of the base 1; the first flange 15 located at the upper end of the third sub-base and the upper end of the fourth base are connected to one end of the first claw arm 21 by bolts through the second bolt hole 18, and the other end of the first claw arm 21 is welded to the middle of the second claw arm 22, and each end of the second claw arm 22 is provided with an elliptical hole; one end of the first claw arm 21 is provided with a third bolt hole 211 matching the second bolt hole 18, and the other end of the first claw arm 21 is welded to the middle of the second claw arm 22, and each end of the second claw arm 22 is provided with an elliptical hole.

[0032] This invention optimizes the structure of the claw 2, utilizing the inclined second claw arm 22 to allow the invention to more easily extend into the guide vane seat. The elliptical hole at the closer end of the second claw arm 22 allows for bolting to the connecting bolt holes on the guide vane seat, while the bolt hole at the farther end of the second claw arm 22 allows for inserting a traction rope to pull and move the invention together with the guide vane seat.

[0033] In use, the base 1 of this utility model consists of four sub-bases. The sub-bases are in the shape of a quarter-circle arc, dividing the base 1 into four parts. The flanges on the left and right sides are axially symmetrical, thus effectively balancing the force on this utility model. In addition, the flanges on the upper and lower sides are rotationally symmetrical. Two adjacent sub-bases are connected by bolts through the first bolt hole 17, and then the claws 2 are connected by bolts through the second bolt hole 18. This makes it convenient to rotate and move this utility model using the pair of flanges, making storage and transportation more convenient. Compared with the design of separate components, using the flanges of the base 1 to connect the claws 2 not only reduces the production cost, but also effectively improves the strength of this utility model.

[0034] Example 2

[0035] Reference Figure 1 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] It also includes a ring-shaped support ring 3, which is fitted inside the base 1, with the outer side wall of the support ring 3 abutting against the inner side wall of the base 1. This increases the structural strength of the invention using the support ring 3.

[0037] A limiting plate 31 extending outward is provided on the outer side wall of the support ring 3, and the limiting plate 31 is sandwiched between one of the first flanges 15 and the second flange 16. Thus, the limiting plate 31 is used to limit the relative position of the limiting plate 31 and the base 1.

[0038] An extension plate 151 is provided at the connection between the first flange 15 and the sub-base, and a notch 161 matching the extension plate 151 is provided at the connection between the second flange 16 and the sub-base. Thus, the extension plate 151 guides the connected sub-base, and more importantly, increases the structural strength of the connection.

[0039] The thickness of the extension plate 151 decreases as it moves further away from the sub-base, thus facilitating insertion into the notch 161. The notch 161 can be a hole, a slot, etc., but is preferably a notch formed by an inclined cut surface.

[0040] In use, a support ring 3 is fitted inside the base 1. The outer side wall of the support ring 3 abuts against the inner side wall of the base 1. An outwardly extending limiting plate 31 is provided on the outer side wall of the support ring 3. The limiting plate 31 is sandwiched between one of the first flanges 15 and the second flange 16. The limiting plate 31 restricts the relative position between the limiting plate 31 and the base 1, thereby increasing the structural strength of this utility model by using the support ring 3. An extension plate 151 is provided at the connection between the first flange 15 and the sub-base. The extension plate 151 guides the connected sub-base and, more importantly, increases the structural strength of the connection.
