Specific embodiment

The invention will be further described with attached drawing combined with specific embodiments below, elaborates in the following description more Details to facilitate a thorough understanding of the present invention, still the present invention obviously can be come with a variety of other ways different from this description it is real It applies, those skilled in the art can make similar popularization according to practical situations without violating the connotation of the present invention, drill It unravels silk, therefore should not be limited the scope of the invention with the content of this specific embodiment.

The embodiment or embodiment of following subject technology schemes for disclosing a variety of different implementations.It is open to simplify The specific example of each element and arrangement is described below in content, and it is not to the present invention that certainly, these, which are only example, Protection scope limited.Such as the fisrt feature then recorded in the description is above second feature or shape above At may include the embodiment that the first and second features are formed by way of directly contacting, also be included in first and The embodiment that supplementary features are formed between two features, to can not directly be contacted between the first and second features.In addition, this In a little disclosures may in different examples repeat reference numerals and/or letter.The repetition be in order to brief and clear, Itself do not indicate each embodiment being discussed and/or interstructural relationship.Further, when first element is with second The mode that element is connected or combines describes, which includes the embodiment party that the first and second elements are connected directly or are bonded to each other Formula also includes so that the first and second interelements ground connection is connected or is bonded to each other using one or more other intervening elements additions.

It should be noted that Fig. 1 to Figure 13 only as an example, its not be according to equal proportion condition draw, and And it should not be construed as limiting in this, as the protection scope to actual requirement of the present invention.

Steam generator 1 is the pith for forming nuclear power station, is used to generate the steam of pushing turbine acting.

Fig. 3 shows the steam generator installed in nuclear island 1, and wherein steam generator 1 is in perpendicular Straight state has the head 11 and underlying tail portion 12 being located above, and the diameter on head 11 is greater than the diameter of tail portion 12,

During transporting nuclear island to, for convenience of transporting, steam generator 1 is in a horizontal state.It is transporting to designated place Afterwards, need first to rotate steam generator 1, that is, around the rotation of center line, then overturn, in place after hung again with ring Nuclear island is hung in be installed.

Fig. 1,2 show a comparative example, in the comparative example, using wirerope 9 by steam generator 1 from support 8 It is rotated after slinging.This mode difficulty is larger and precision is not high, needs to repeat the operation several times to complete steam generator 1 Rotary work, this needs the steam generator 1 that repeatedly rises and falls in the process, causes construction efficiency low.

To solve the problems, such as that construction efficiency is low, as shown in Fig. 4,5,6,7,8, the embodiment provides a kind of complete The support component 2 of new nuclear island steam generator.Support component 2 includes rotation support component 21, and rotation support component 21 includes Driving assembly 211 and multiple idler wheels 212；Multiple idler wheels 212 are configured to positioned at the lower section of steam generator 1, and are respectively supported The side wall of top support steam generator 1, to rotatably support steam generator 1；Driving assembly 211 is for driving at least one A idler wheel 212 rotates, so that idler wheel 212 be made to drive steam generator 1 around center line rotation by frictional force.

The center line is the axis of steam generator 1, and the pivot center of idler wheel 212 is chosen as setting with the centerline parallel It sets.

Since idler wheel 212 can play the role of support simultaneously and steam generator 1 is driven to rotate, compared to above-mentioned Comparative example, steam generator 1, which is not necessarily to be lifted, to realize rotation in the position being supported, this improves operating efficiency.

With continued reference to Fig. 4, rotating support component 21 further includes base support 210, and multiple idler wheels 212 are pivotally connected in pedestal On bracket 210.In Fig. 4, base support 210 is divided to for two parts, supports the head 11 and tail portion of steam generator 1 respectively 12.In a further embodiment, base support 210 also can be made into an entirety.

To realize to the support in 1 switching process of steam generator, as shown in Fig. 9,10,11,12,13, support component 2 is also Including turning-over support component 22, turning-over support component 22 includes turnover bracket 220, connector 221, pin shaft part 222 and fastener 223；Pin shaft part 222 is configured to removably one end across the upper end of turnover bracket 220 and connector 221, so that connection Part 221 and turnover bracket 220 are pivotally connected；Fastener 223 is used for the tail of the other end of connector 221 and steam generator 1 The center of the end face in portion 12 is fixedly connected, so that connector 221 can during steam generator 1 is lifted to vertical state Rotationally support steam generator 1.

Since turnover bracket 220 and connector 221 can be removably pivotally connected by pin shaft part 222, pacifying It can make turnover bracket 220 by mobile turnover bracket 220 before dress pin shaft part 222 and be already fixed to steam generator 1 Connector 221 at the center of the end face of tail portion 12 is aligned, and is inserted into pin shaft part 222 later.Avoid the need for moving steam hair Device 1 is given birth to realize the case where turnover bracket 220 is aligned with connector 221.

During the head of steam generator 1 11 is lifted to vertical state, connector 221 is with pin shaft part 222 Center follows steam generator 1 to be rotated, and is supported to the end face of the tail portion of steam generator 1 12.

In one embodiment, connector 221 includes substrate 221c, the first vertical plate 221a and the second vertical plate 221b, and first Vertical plate 221a and the second vertical plate 221b are respectively connected on the same side of substrate 221c and are oppositely arranged；Pin shaft part 222 is configured to The first vertical plate 221a, the upper end of turnover bracket 220, the second vertical plate 221b are sequentially passed through, so that connector 221 and turnover bracket 220 are pivotally connected；Fastener 223 is for substrate 221c to be fixedly connected with the center of the end face of the tail portion 12 of steam generator 1. First vertical plate 221a and the second vertical plate 221b can weld in substrate 221c

In one embodiment, connecting hole 221c-1 is offered on substrate 221c, one end of fastener 223 passes through connecting hole And be fixedly connected with the center of the end face of the tail portion of steam generator 1 12, so that substrate 221c be connect with steam generator 1. Fastener 223 can be fastening bolt, and staff can be used hydraulic spanner and carry out tightening operation.

In one embodiment, turnover bracket 220 include pedestal 220a and rack body 220b, the one of rack body 220b End is fixedly connected on pedestal 220a, and the other end and connector 221 are pivotally connected.

In one embodiment, the quantity of connecting hole 221c-1 is multiple, and the two sides of the first vertical plate 221a and second vertical The two sides of plate 221b are provided with connecting hole 221c-1.Being designed in this way can make substrate 221c stress more uniform.

Although the present invention is disclosed as above with preferred embodiment, it is not for limiting the present invention, any this field skill Art personnel without departing from the spirit and scope of the present invention, can make possible variation and modification, all without departing from this hair The content of bright technical solution, according to the technical essence of the invention any modification to the above embodiments, equivalent variations and repair Decorations, each fall within the protection scope that the claims in the present invention are defined.
