Description

Technical Field

[0001] The present invention relates to a support structure and an assembly method thereof, and particularly to a support structure adapted to a cylindrical pressure-bearing device and an assembly method thereof. Background Art

[0002] In the actual application environment of industrial equipment, operations such as supporting and rotating equipment may be involved. Therefore, additional mechanical loads are introduced to the industrial equipment. It is necessary to separately design an independent support structure to bear the mechanical loads, complete the established operation tasks, and reduce the strength pressure of the industrial equipment itself.

[0003] Different from traditional industrial equipment, the cylindrical pressure-bearing device generally designs the support structure at the position of the centroid of the device, and the centroid of the device is located at the corresponding position of the middle cylinder section of the cylindrical pressure-bearing device. Therefore, in order to reduce the lever arm between the operating mechanical load and the centroid, the support structure is generally directly welded to the cylinder wall of the cylindrical pressure-bearing device. If there is no pressure load inside the cylindrical pressure-bearing device, ensuring the welding quality can ensure safety, and the structure is also relatively reasonable. However, there is usually a pressure load inside the cylindrical pressure-bearing device. At this time, the cylinder wall will deform due to the internal pressure load, and the welding joint of the support structure and the corresponding cylinder wall will deform due to the operating load. Therefore, the internal pressure load of the device and the mechanical load brought by the operation will be concentrated at the welding joint of the support structure to produce coupling, resulting in the safety problem of insufficient strength of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0060] In order to make the advantages and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] As Figure 1As shown in the figure, it is the support structure of an existing cylindrical pressure-bearing device. The support structure 2 is symmetrically welded to the wall of the middle section of the cylindrical pressure-bearing device 1. After a large pressure load is applied inside the cylindrical pressure-bearing device 1, if an operating load is superimposed on the support structure 2, the coupling of the internal pressure load and the mechanical load brought by the operation will occur at the welding position between the support structure 2 and the wall, and a large stress concentration phenomenon will occur on the wall and the welding position, affecting the structural safety of the cylindrical pressure-bearing device 1. Considering that a first flange and a second flange are usually respectively arranged at both ends of the middle section of the cylindrical pressure-bearing device 1, the present invention designs a new support structure and connects the support structure to the first flange and the second flange of the middle section of the cylindrical pressure-bearing device 1, avoiding transmitting the mechanical load brought by the operation to the wall of the middle section of the cylindrical pressure-bearing device 1, realizing the decoupling of the internal pressure load and the mechanical load brought by the operation on the wall, and effectively increasing the structural safety of the cylindrical pressure-bearing device.

[0062] As Figure 2 shown, a support structure adapted to a cylindrical pressure-bearing device is a split structure, including two support units with the same structure. The two support units are symmetrically arranged on the outer side wall of the middle section of the cylindrical pressure-bearing device 1.

[0063] As Figure 3 shown, each support unit respectively includes a rotating support shaft 3, a connecting plate 4, a first flange side baffle 5, a second flange side baffle 6, a plurality of first connecting screws, a plurality of second connecting screws, a plurality of bolts, a plurality of first pins, and a plurality of second pins.

[0064] As Figure 4 shown, the connecting plate 4 is a plate-like structure, and a plurality of avoiding holes are respectively opened at positions near its left and right sides. Two first connecting through holes 11 communicating with the corresponding avoiding holes are respectively opened at positions corresponding to each avoiding hole on the left and right side end faces of the connecting plate 4; a first pin blind hole 13 is respectively opened at positions corresponding to the positions between adjacent two avoiding holes on the left and right side end faces of the connecting plate 4.

[0065] As Figure 5 、 Figure 6 shown, the first flange side baffle 5 and the second flange side baffle 6 have exactly the same structure, and they are both plate-like structures and are respectively arranged on the left and right side end faces of the connecting plate 4. Specifically, a plurality of threaded blind holes 16 corresponding to the first connecting through holes 11 at the left and right ends of the connecting plate 4 are respectively opened on the first flange side baffle 5 and the second flange side baffle 6. One end of a plurality of first connecting screws is used to pass through the corresponding first connecting through holes 11 through the avoiding holes of the connecting plate 4 and connect with the threaded blind holes 16 of the first flange side baffle 5 or the second flange side baffle 6, so as to realize the fixed connection between the connecting plate 4 and the first flange side baffle 5 and the second flange side baffle 6.

[0066] A plurality of first pin through-holes 14 corresponding one-to-one to the first pin blind holes 13 on the left and right end faces of the connecting plate 4 are respectively formed in the first flange side baffle 5 and the second flange side baffle 6. A plurality of first pins are used to respectively pass through the plurality of first pin through-holes 14 and the corresponding first pin blind holes 13 to achieve positioning. Among them, the first pin through-holes 14 on the first flange side baffle 5 are positioned with the corresponding first pin blind holes 13 to ensure the relative accuracy between the connecting plate 4 and the cylindrical pressure-bearing device 1, while the first pin through-holes 14 on the second flange side baffle 6 are positioned with the first pin blind holes 13 to ensure the repeated disassembly and installation accuracy of the connecting plate 4.

[0067] In other embodiments of the present invention, the first pin blind holes 13 may also be provided only on either the left or right end face of the connecting plate 4. Correspondingly, only the corresponding first pin through-holes 14 need to be provided on the first flange side baffle 5 or the second flange side baffle 6 connected thereto.

[0068] In addition, an installation surface is respectively provided at the outer end of each first pin through-hole 14 of the present invention, and a retaining cap 10 is respectively installed on each installation surface to prevent the first pin from coming out during use.

[0069] The inner end face profiles of the first flange side baffle 5 and the second flange side baffle 6 are both adapted to the outer wall of the middle cylinder section of the cylindrical pressure-bearing device 1; a plurality of second connection through-holes 15 are provided at positions of the first flange side baffle 5 and the second flange side baffle 6 close to the inner end face. A plurality of bolts are used to respectively pass through the corresponding second connection through-holes 15 and connect with the first flange or the second flange to achieve the fixed connection between the first flange side baffle 5, the second flange side baffle 6 and the cylindrical pressure-bearing device 1, that is, to achieve the fixed connection between the support structure of the present invention and the cylindrical pressure-bearing device 1.

[0070] To ensure the connection accuracy between the support structure and the cylindrical pressure-bearing device 1, in the present invention, two pre-assembly holes 9 and two second pin through-holes 8 are respectively provided at positions close to the inner sides of the first flange side baffle 5 and the second flange side baffle 6. One end of each of the two second connecting screws is respectively used to pass through the two pre-assembly holes 9 of the first flange side baffle 5 and connect with two corresponding threaded holes of the first flange, so as to realize the pre-fixation of the first flange side baffle 5 and the first flange before connection; one end of each of the other two second connecting screws is respectively used to pass through the two pre-assembly holes 9 of the second flange side baffle 6 and connect with two corresponding threaded holes of the second flange, so as to realize the pre-fixation of the second flange side baffle 6 and the second flange before connection, facilitating subsequent connection operations and ensuring the installation accuracy. A plurality of second pins are respectively used to pass through the two second pin through-holes 8 and realize positioning with the corresponding pin holes of the first flange or the second flange. Among them, the two second pin through-holes 8 on the first flange side baffle 5 are positioned with the two pin holes of the first flange, so as to ensure the relative position accuracy of the first flange side baffle 5 relative to the cylindrical pressure-bearing device 1, that is, to ensure the relative position accuracy of the entire support structure relative to the cylindrical pressure-bearing device 1, while the two second pin through-holes 8 of the second flange side baffle 6 are positioned with the two pin holes of the second flange, so as to ensure the repeated disassembly and installation accuracy of the entire support structure.

[0071] The connecting plate 4 is provided with fixing holes adapted to the outer diameter of the inner end of the rotating support shaft 3, and a plurality of first mounting holes 7 are provided at positions corresponding to the outer periphery of the fixing holes; the rotating support shaft 3 is vertically mounted on the connecting plate 4 through the plurality of first mounting holes 7, and its inner end extends into the fixing holes to achieve fixed positioning. It should be noted that when the two support units in the present invention are symmetrically mounted on the cylindrical pressure-bearing device 1, it is necessary to ensure that the central axis connection line of the rotating support shafts 3 in the two support units passes through the centroid of the cylindrical pressure-bearing device.

[0072] For the convenience of installation, the length of the connecting plate 4 is usually designed to be smaller, but this usually causes a certain gap between the right end face of the connecting plate 4 and the second flange side baffle 6 after the connecting plate 4, the first flange side baffle 5 and the first flange of the cylindrical pressure-bearing device 1 are connected. Therefore, the present invention also provides a plurality of gaskets, which are used to be arranged between the right end face of the connecting plate 4 and the second flange side baffle 6 to achieve stable connection.

[0073] In addition, in this embodiment, a plurality of weight-reducing grooves 12 are provided on the connecting plate 4 to reduce the weight of the entire support structure, and the specific layout principle is that the deformations of the front and rear connecting plates 4 in the length, width and thickness directions are quite the same for the design of the plurality of weight-reducing grooves 12.

[0074] To achieve the connection of the present invention, when the first flange side baffle 5 is connected to the first flange, the original connection through-holes on the first flange can be utilized. Only the length of the bolt needs to be increased so that one end of the bolt sequentially passes through the second connection through-hole 15 on the first flange side baffle 5, the original connection through-hole on the first flange, and is connected to the threaded hole of other external connection devices. Additionally, during pre-assembly and positioning, corresponding threaded holes and pin holes need to be opened on the first flange. Correspondingly, the design of the second flange is the same as that of the first flange.

[0075] The assembly method of the above-mentioned support structure adapted to a cylindrical pressure-bearing device specifically includes the following steps:

[0076] Step 1, first install one of the support units. Make the two second connection screws in this support unit respectively pass through the two pre-assembly holes 9 on the first flange side baffle 5 and be connected to the threaded holes on the first flange of the cylindrical pressure-bearing device 1 to achieve pre-fixing of the first flange side baffle 5 and the first flange; then make the two second pins in this support unit respectively pass through the two second pin through-holes 8 on the first flange side baffle 5 and the two pin holes on the first flange in sequence to ensure the relative position accuracy of the first flange side baffle 5 relative to the cylindrical pressure-bearing device 1.

[0077] Make the two second connection screws in this support unit respectively pass through the two pre-assembly holes 9 on the second flange side baffle 6 and be connected to the threaded holes on the second flange of the cylindrical pressure-bearing device 1 to achieve pre-fixing of the second flange side baffle 6 and the second flange; then make the two second pins in this support unit respectively pass through the two second pin through-holes 8 on the second flange side baffle 6 and the two pin holes on the second flange in sequence to ensure the relative position accuracy of the second flange side baffle 6 relative to the cylindrical pressure-bearing device 1.

[0078] Make multiple bolts in this support unit respectively pass through the second connection through-hole 15 on the first flange side baffle 5, the connection through-hole on the first flange, and be connected to the threaded hole of the external device in sequence to achieve complete fixation of the first flange side baffle 5 and the first flange; at the same time, make multiple bolts in this support unit respectively pass through the second connection through-hole 15 on the second flange side baffle 6, the connection through-hole on the second flange, and be connected to the threaded hole of the external device in sequence to achieve complete fixation of the second flange side baffle 6 and the second flange.

[0079] Step 2, pass multiple first connection screws through the corresponding first connection through-holes 11 through the avoidance holes on the left side of the connecting plate 4 and be connected to the threaded blind holes 16 on the first flange side baffle 5, and then pass multiple first pins through the first pin through-holes 14 on the first flange side baffle 5 and the first pin blind holes 13 on the left end face of the connecting plate 4 in sequence for positioning to ensure the relative position accuracy between the connecting plate 4 and the cylindrical pressure-bearing device 1.

[0080] Step 3. Correspondingly, install another support unit in the manner of Steps 1-2. On this basis, the relative position accuracy of the first mounting holes 7 on the two symmetrically arranged connecting plates 4 can be ensured, and further the relative position accuracy of the two rotating support shafts 3 can be ensured.

[0081] Step 4. Pass the remaining first connecting screws in the two support units through the avoidance holes on the right side of the connecting plate 4 and connect them to the threaded blind holes 16 of the second flange side baffle 6 through the corresponding first connecting through holes 11. During connection, if there is a gap between the right end face of the connecting plate 4 and the second flange side baffle 6, add corresponding gaskets according to the existing gap to achieve a firm connection between the right end face of the connecting plate 4 and the second flange side baffle 6.

[0082] Finally, sequentially pass the remaining first pins in the two support units through the first pin through holes 14 on the second flange side baffle 6 and the first pin blind holes 13 on the right end face of the connecting plate 4 to achieve positioning, so as to ensure the repeated disassembly and installation accuracy of the connecting plate 4, and complete the assembly of the support structure of the cylindrical pressure-bearing equipment.

[0083] After the support structure of the present invention is applied to the cylindrical pressure-bearing equipment 1, a rotary drive device can be connected to the rotating support shaft 3 of the support structure to rotate the rotating support shaft 3, thereby driving the rotation of the cylindrical pressure-bearing equipment 1. In addition, the cylindrical pressure-bearing equipment 1 can also be integrally fixed at a certain position through the rotating support shafts 3 on both sides of the support structure to achieve the support function.

[0084] The above is only used to illustrate the technical solutions of the present invention, rather than to limit it. For those of ordinary professional skills in the art, the specific technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions protected by the present invention.
