Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical product packaging, in particular to a packaging frame structure for annular components of a steam turbine. Background Art
[0002] As a large-scale mechanical product, steam turbines are usually delivered in parts. They are first pre-assembled in the production plant, disassembled into various parts, and then transported to the power plant for installation.
[0003] Steam turbine parts are generally large in size and heavy in weight. The annular parts are usually finely processed products, which require high packaging and protection. Previously, such parts generally used the national standard universal packaging box base, with a single annular part placed flat on 2-3 pads, and then packaged into a box. Although this type of packaging structure can effectively protect the annular parts, the space utilization rate of the packaging structure is low. Each annular part requires a packaging structure. At the same time, each annular part requires a packaging box. If there are multiple annular parts with the same structure and size that need to be packaged, more wood and more time are required.
[0004] Therefore, the existing packaging structure has the following problems: since a single annular component is boxed, the space utilization rate is low. When multiple annular components need to be packaged, there is repeated packaging, which is inefficient and uses a large number of product packaging structures, resulting in waste of wood and transitional packaging, while increasing the logistics and transportation costs of the products. Summary of the invention
[0005] The utility model aims to provide a steam turbine annular component packaging frame structure which can effectively improve space utilization, use less packaging frame wood and has low use cost in view of the deficiencies of the prior art.
[0006] The technical purpose of the utility model is achieved through the following technical solutions:
[0007] A steam turbine annular component packaging frame structure, comprising a base, left and right side frames fixed on the base, and front and rear side frames; the base is provided with longitudinal sleepers and transverse sleepers; the longitudinal sleepers include end woods arranged at the left and right ends of the base and middle sleepers between the end woods; the transverse sleepers include front support sleepers and rear support sleepers symmetrically arranged on the longitudinal sleepers; the distance between the front and rear side frames is slightly larger than the diameter of the annular component, the annular component is vertically erected on the transverse sleepers, and the bottom of the annular component does not contact the upper end surface of the bottom plate of the base; the height of the front and rear side frames is greater than or equal to the radius of the annular component; a limiting crossbeam for limiting the lateral movement of the annular component is detachably connected between the longitudinal beams of the front and rear side frames; when the annular components are multiple, the limiting crossbeams are multiple, and the left and right sides of the annular component respectively abut against the crossbeams / limiting crossbeams and the limiting crossbeams of the left and right side frames.
[0008] The tops of the opposite sides of the front supporting sleeper and the rear supporting sleeper are respectively provided with inclined surfaces.
[0009] There are columns at the four corners of the base, and the upper ends of the columns are connected by two cross beams and two longitudinal beams to form left and right side frames and front and rear side frames; an auxiliary column is also provided in the middle between the columns, and the lower part of the auxiliary column and the upper part of the adjacent column are connected to each other by a diagonal brace.
[0010] The lower part between the left and right columns on the base and the auxiliary columns is also reinforced by reinforcing wood.
[0011] The longitudinal sleepers also include auxiliary sleepers arranged between the middle sleepers and the end sleepers.
[0012] The base also includes a plurality of slides arranged under the bottom plate; the slides are parallel to the length direction of the bottom plate and are arranged at intervals along the width direction of the bottom plate.
[0013] The slide is T-shaped; the slide comprises a long slide and a short slide arranged up and down along the length direction of the bottom plate.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The utility model changes the original placement of the annular components, replacing the horizontal placement with a vertical placement.

[0032] like Figure 1 , Figure 2As shown, the base 1 includes a bottom plate 11 and a plurality of slides 12 arranged under the bottom plate 11; the slides 12 are parallel to the length direction of the bottom plate 11 and are arranged at intervals along the width direction of the bottom plate 11. In actual use, the bottom plate 11 is rectangular, and a left frame 2, a right frame 3, a front frame 4 and a rear frame 5 are fixedly arranged on the four sides of the bottom plate 11. Three slides 12 are fixedly arranged under the bottom plate 11 along its width direction. The three slides 12 are respectively arranged at the front side, the middle part and the rear side under the bottom plate 11. The slide 12 is T-shaped as a whole, and the slide 12 includes a long slide 121 and a short slide 122 arranged up and down along the length direction of the bottom plate 11. With this structure, it is convenient for the wire rope to pass through during hoisting, which is convenient for hoisting.
[0033] like Figure 1 , Figure 2 As shown, columns 13 are provided at the four corners of the base 1, and the upper ends of the columns 13 are connected by two cross beams 101 and two longitudinal beams 102 to form left and right side frames and front and rear side frames; an auxiliary column 8 is also provided in the middle of the bottom plate 11 between the columns 13, and the lower part of the auxiliary column 8 is connected to the upper parts of the two adjacent columns 13 by a diagonal brace 9. In actual use, square columns 13 are fixed at the four corners of the base 1, and the upper ends of the columns 13 are connected by two parallel cross beams 101 and two longitudinal beams 102 to form the left side frame 2, the right side frame 3, the front side frame 4 and the rear side frame 5; the frame is formed by a half-lap method. The lower part of the auxiliary column 8 is connected to the upper parts of the two adjacent columns 13 by a diagonal brace 9. An auxiliary column 8 is also provided in the middle of the base 1 between the two columns 13; there are four auxiliary columns 8, corresponding to the left and right side frames and the front and rear side frames respectively. The lower end of the auxiliary column 8 is connected to the base 11, and the upper end thereof is respectively connected to the lower ends of the two horizontal beams 101 and the two longitudinal beams 102. The lower part of the auxiliary column 8 and the upper parts of the two adjacent columns 13 are connected to each other through the diagonal brace 9. The auxiliary column 8 and the diagonal brace 9 are added to ensure the stability and safety of the frame.
[0034] In actual use, the lower part between the left and right columns 13 on the base 1 and the auxiliary columns 8 is further reinforced by reinforcing wood 81 .
[0035] like Figure 1 — Figure 3As shown, the base 1 is provided with longitudinal sleepers 6 and transverse sleepers 7; the longitudinal sleepers 6 include end woods 61 arranged at the left and right ends of the base 1 and a middle sleeper 62 between the end woods 61; the transverse sleepers 7 include front support sleepers 71 and rear support sleepers 72 symmetrically arranged on the longitudinal sleepers 6; the distance between the front and rear side frames is slightly larger than the diameter of the annular component, the annular component is vertically erected on the transverse sleepers 7, and the bottom of the annular component does not contact the bottom plate 11. In actual use, the length of the longitudinal sleepers 6 is equivalent to the width of the bottom plate 11. In order to ensure the connection strength, the longitudinal sleepers 6 are directly connected to the sliding wood 12,
[0036] The bottom plate 11 is composed of two bottom plates arranged on both sides of the middle sleeper 62. Specifically, the longitudinal sleeper 6 is fixed to the slide 12 by studs, that is, the end wood 61 and the middle sleeper 62 between the end wood 61 are fixed to the slide 12 by studs respectively; the bottom plate 11 fixed to the slide 12 is arranged between the end wood 61 and the middle sleeper 62. The middle sleeper 62 is used to increase the strength of the front support sleeper 71 and the rear support sleeper 72 to realize the function of bearing the annular product.
