Description

Technical Field

[0001] The utility model relates to a hoisting and fixing device, in particular to a hoisting and fixing device for a water guiding mechanism of a tubular unit. Background Art

[0002] The water-guiding mechanism of the cross-flow unit includes an inner ring, an outer ring, and a guide vane installed between the inner and outer rings, and a lifting point is provided on the outer ring. When the water-guiding mechanism is installed, repaired, etc., it is necessary to lift the water-guiding mechanism. In order to facilitate the lifting of the water-guiding mechanism, the existing operation method is to fix an X-shaped bracket on the downstream side of the water-guiding mechanism, and then fix the sling on the lifting point and the X-shaped bracket, and finally use the lifting equipment to lift the water-guiding mechanism, as shown in the patent technology with application number CN202311063110.8. In this patented technology, the X-shaped bracket can support the water-guiding mechanism horizontally during maintenance, and can also eliminate the disadvantage of uneven quality at both ends of the water-guiding mechanism to a certain extent. However, this technology cannot fix the water-guiding mechanism well. Due to the large deadweight of the water-guiding mechanism, its inner ring and outer ring are prone to deformation during the lifting process, affecting the quality of the water-guiding mechanism. Utility Model Content

[0003] In order to solve the above problems, the present application provides a hoisting and fixing device for a water guiding mechanism of a cross-flow unit, which can support and fix the inner ring and the outer ring of the water guiding mechanism, and effectively prevent the water guiding mechanism from deforming.

[0004] The purpose of the utility model is achieved through the following technical scheme: a water-guiding mechanism hoisting and fixing device for a cross-flow unit, comprising: a bracket; a plurality of third support members, vertically arranged on the bracket; a plurality of inner ring fixing plates, respectively arranged on the top of the third support members and distributed in a circular ring shape, for fixing the inner ring of the water-guiding mechanism; a plurality of outer ring fixing plates, distributed in a circular ring shape on the bracket, for fixing the outer ring of the water-guiding mechanism; the inner ring fixing plate and the outer ring fixing plate are both provided with mounting holes.

[0005] The water guiding mechanism outer ring and the water guiding mechanism inner ring of the water guiding mechanism of the tubular unit are connected into a whole through the tubular unit water guiding mechanism hoisting and fixing device, so as to effectively prevent the water guiding mechanism from being deformed during hoisting.

[0006] Furthermore, the bracket includes two first support members arranged in parallel and two second support members arranged in parallel and perpendicular to the two first support members; the outer ring fixing plates are respectively arranged on the two first support members and the two second support members.

[0007] The third support members are respectively arranged vertically at the intersections of the first support member and the second support member, so that the first support member, the second support member and the third support member are fixed more firmly.

[0008] The mounting hole is an arc-shaped slot hole.

[0009] The outer ring fixing plate is provided with a supporting plate for supporting the outer ring of the water guide mechanism. The supporting plate can play a certain supporting role on the outer ring of the water guide mechanism, and further prevent the water guide mechanism from being deformed.

[0010] The first support member and the second support member are both I-beams.

[0011] Two L-shaped blocks are arranged on the lower surface of the outer ring fixing plate, and the two L-shaped blocks form a slot together. The upper panels of the first support and the second support are inserted into the slots to enable the outer ring fixing plate to move. The upper panels of the first support and the second support are both provided with adjustment holes distributed along their lengths. Adjustment bolts for positioning the outer ring fixing plate are installed in the adjustment holes near the two sides of the outer ring fixing plate, and adjustment nuts are installed on the adjustment bolts. The position of the outer ring fixing plate can be fine-tuned so that the mounting holes thereon are more accurately aligned with the threaded holes on the outer ring wing plate of the outer ring of the water guide mechanism.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] (1) The utility model can connect the water guide mechanism outer ring and the water guide mechanism inner ring of the water guide mechanism of the tubular unit into a whole, thereby effectively preventing the water guide mechanism from being deformed during lifting.

[0014] (2) The position of the outer ring fixing plate of the utility model can be finely adjusted so that the mounting holes thereon can be more accurately aligned with the threaded holes on the outer ring wing plate of the outer ring of the water guide mechanism, making it easier to fix the utility model on the water guide mechanism.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0026] Example 1

[0027] like Figure 1 , 2 As shown, this embodiment discloses a device for hoisting and fixing a water guide mechanism of a tubular unit, which comprises: a bracket, a third support member 3, an inner ring fixing plate 13 and an outer ring fixing plate 4. The bracket comprises two first support members 1 arranged in parallel and two second support members 2 arranged in parallel and perpendicular to the two first support members 1; thus, the two first support members 1 and the two second support members 2 together form a bracket in the shape of a "well".

[0028] The number of the third support members 3 is four, and the four third support members 3 are respectively arranged vertically at the intersections of the first support member 1 and the second support member 2, so that the connection between the first support member 1, the second support member 2 and the third support member 3 can be more stable. Of course, the number of the third support members 3 can also be set according to the situation, such as eight, two, etc. In this case, the third support members 3 are not necessarily arranged at the intersection of a support member 1 and the second support member 2, and the third support members 3 only need to be distributed in a ring shape on the bracket.

[0029] The number of inner ring fixing plates 13 is the same as the number of third support members 3. In this embodiment, the number of inner ring fixing plates 13 is set to four. The four inner ring fixing plates 13 are respectively arranged on the top of the four third support members 3 and are distributed in a circular ring shape to match the shape of the inner ring wing plate of the inner ring of the water guiding mechanism. The four inner ring fixing plates 13 are used to fix the inner ring of the water guiding mechanism.

[0030] The outer ring fixing plates 4 are distributed on the bracket in a circular ring shape to match the shape of the outer ring wing plates 8 of the water guide mechanism outer ring 7, and are used to fix the water guide mechanism outer ring 7. When specifically set, the number of the outer ring fixing plates 4 can also be set according to actual conditions, for example, set to eight, four, two, etc. In this embodiment, the number of the outer ring fixing plates 4 is set to eight, that is, one outer ring fixing plate 4 is respectively set at both ends of each first support member 1 and the second support member 2.

[0031] In order to fix the hoisting fixture on the water guide mechanism, the inner ring fixing plate 13 and the outer ring fixing plate 4 are both provided with mounting holes 5. In the specific setting, the mounting holes 5 are arc-shaped slot holes.

[0032] The outer ring wing plate 8 of the outer ring 7 of the water guide mechanism and the inner ring wing plate of the inner ring of the water guide mechanism are both provided with threaded holes. The hoisting and fixing device of the water guide mechanism of the flow-through unit in this embodiment is installed on the downstream side of the water guide mechanism of the flow-through unit. During installation, the hoisting and fixing device of the water guide mechanism of the flow-through unit is erected, and the third support member 3 is extended into the water guide mechanism of the flow-through unit. Bolts are passed through the mounting holes 5 on the inner ring fixing plate 13 and then screwed into the threaded holes on the inner ring wing plate of the inner ring of the water guide mechanism, thereby fixing the inner ring of the water guide mechanism. Then, bolts are passed through the mounting holes 5 on the outer ring fixing plate 4 and then screwed into the threaded holes on the outer ring wing plate 8 of the outer ring 7 of the water guide mechanism, thereby fixing the outer ring 7 of the water guide mechanism. During lifting, the sling is fixed to the lifting point of the outer ring 7 of the water guide mechanism and the hoisting and fixing device. The arc-shaped slot hole can better align the threaded holes on the outer ring wing plate 8 and the inner ring wing plate. The hoisting and fixing device of the present embodiment is supported around the outer ring 7 of the water guiding mechanism by a "well"-shaped bracket to prevent the outer ring 7 of the water guiding mechanism from being deformed; the inner ring of the water guiding mechanism is supported by the third support member 3 to prevent the inner ring of the water guiding mechanism from being deformed; at the same time, the outer ring 7 of the water guiding mechanism of the cross-flow unit and the inner ring of the water guiding mechanism are connected into a whole by the hoisting and fixing device, so as to better ensure that the water guiding mechanism will not be deformed during lifting.

[0033] Example 2

[0034] like Figure 3 As shown, in this embodiment, based on the embodiment 1, a support plate 6 for supporting the outer ring 7 of the water guide mechanism is arranged on the outer ring fixing plate 4. When the hoisting and fixing device is erected, the support plates 6 on the upper and middle outer ring fixing plates 4 are located on the inner side of the outer ring fixing plates 4, while the support plates 6 on the lower outer ring fixing plates 4 are located on the outer side of the outer ring fixing plates 4, as shown in FIG. Figure 3 When the hoisting fixture is installed on the downstream side of the water guide mechanism of the cross-flow unit, the support plates 6 on the upper and middle outer ring fixing plates 4 are supported on the inner side of the outer ring 7 of the water guide mechanism, while the support plates 6 on the lower outer ring fixing plates 4 are supported under the outer ring wing plates 8, as shown in FIG. Figure 4 As shown. In this way, the hoisting fixture can better support and fix the water guide mechanism.

[0035] In addition, in this embodiment, the first support member 1 and the second support member 2 are both I-beams. Figure 5-7 As shown, two L-shaped blocks 12 are arranged at intervals on the lower surface of the outer ring fixing plate 4, and a slot 14 is formed between the two L-shaped blocks 12. The two sides of the upper panel of the I-beam are respectively inserted into the slots 14, so that the outer ring fixing plate 4 can move along the I-beam, so that the position of the outer ring fixing plate 4 can be adjusted, so that the outer ring fixing plate 4 can be better aligned with the threaded holes on the outer ring wing plate 8.

[0036] The upper panels of the first support member 1 and the second support member 2 are both provided with adjustment holes 9 distributed along the length direction thereof. When the position of the outer ring fixing plate 4 is adjusted, the adjustment bolts 10 are passed through the adjustment holes 9 on both sides of the outer ring fixing plate 4, and then the adjustment nuts 11 are screwed on the adjustment bolts 10, and the outer ring fixing plate 4 is limited and fixed by the adjustment bolts 10 on both sides of the outer ring fixing plate 4. It should be noted that the height of the adjustment bolts 10 and the adjustment nuts 11 only needs to be able to block the outer ring fixing plate 4, and they cannot exceed the surface of the outer ring fixing plate 4, otherwise it will affect the fixation between the outer ring fixing plate 4 and the outer ring wing plate 8.

[0037] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0038] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
