[0033] The cylindrical rounding structure of the present application is used to support the inner wall of the cylindrical structure and ensure the roundness of the cylindrical structure.

[0034] Figure 1It is a front view of the cylinder support device of the utility model. The cylinder support device of the present application includes an inner ring plate 1, an outer support plate 2 and a plurality of support members 3. The inner ring plate 1 and the outer support plate 2 are both annular, with the radial extension direction of the inner ring plate 1 as the radial direction and the axial direction of the inner ring plate 1 and the outer support plate 2 as the axial direction. The outer support plate 2 is arranged around the outer periphery of the inner ring plate 1 at intervals, and a plurality of support members 3 are connected between the inner ring plate 1 and the outer support plate 2. The plurality of support members 3 are arranged at intervals along the circumference of the inner ring plate 1, and each support member 3 extends along the radial direction of the inner ring plate 1. The outer support plate 2 includes a plurality of outer arc plates 21 and a connecting block 22 connected between any two adjacent outer arc plates 21; the plurality of outer arc plates 21 and the plurality of connecting blocks 22 together enclose a ring shape. Among them, the length of the support member 3 can be adjusted, thereby adjusting the distance between the outer support plate 2 and the inner ring plate 1, and the outer arc plate 21 can be connected to different positions on the connecting block 22, thereby adjusting the outer diameter of the outer support plate 2.

[0035] Specifically, the outer support plate 2 and the inner ring plate 1 are arranged in an inner and outer ring with intervals, and a plurality of support members 3 with adjustable lengths are connected between the inner ring plate 1 and the outer support plate 2, and the plurality of support members 3 extend along the radial direction of the inner ring plate 1, so that the plurality of support members 3 are axially arranged on the inner ring plate 1 in a radial shape. The outer support plate 2 includes outer arc plates 21 and connecting blocks 22 which are sequentially connected and enclose an annular structure, and the outer arc plates 21 located on opposite sides of the connecting block 22 can be connected to different positions on the connecting block 22. In use, by extending or shortening the support members 3, the outer arc plates 21 are moved away from or close to the inner ring plate 1, and the adjacent outer arc plates 21 can adjust the positions connected to the connecting blocks 22, thereby making the adjacent outer arc plates 21 move away from each other and expand the outer diameter of the outer support plate 2, or making the adjacent outer arc plates 21 move close to each other and reduce the outer diameter of the outer support plate 2.

[0036] The outer diameter of the outer support plate 2 is adjustable, so that the outer support plate 2 can fit and support the inner wall of the external cylinder, which is convenient for adjusting the position of the equipment and convenient for disassembly and assembly. At the same time, the connecting block 22 is connected between two adjacent outer arc plates 21, so that multiple outer arc plates 21 form a whole, which can limit the movement direction of the outer arc plate 21, so that the outer arc plate 21 can move in the radial direction of the external cylinder, and reduce the torsional deformation and offset dislocation of the two ends of the outer arc plate 21 along the axial direction of the external cylinder, improve the activity stability of the outer arc plate 21, ensure the overall roundness of the cylinder product, and improve the product precision.

[0037] Reference Figure 2 The inner ring plate 1 of this embodiment includes two relatively spaced ring plates 11, the two ring plates 11 can be supported by a plurality of spaced ribs, and a plurality of support members 3 are arranged between the two ring plates 11. In addition, the inner ring plate 1 can also be an annular plate.

[0038] In this embodiment, the inner ring plate 1 is concentrically arranged with the outer support plate 2; each support member 3 is symmetrically arranged with the inner ring plate 1 as the center. The inner ring plate 1 is concentrically arranged with the outer support plate 2 and is arranged in an inner and outer ring, and the axis of the inner ring plate 1, the outer support plate 2 and the external cylinder are collinear, so that the radial spacing between the inner ring plate 1 and the outer support plate 2 is consistent, which is convenient for installation. At the same time, each support member 3 extends along the radial direction of the inner ring plate 1 and is distributed in a central symmetrical manner, so that the outer support plate 2 is more evenly stressed, ensuring that the support force on the inner wall of the cylinder is more even, and improving the support effect on the inner wall of the cylinder.

[0039] The outer support plate 2 includes a plurality of outer arc plates 21 and a connecting block 22. There are two or more outer arc plates 21, and the number of connecting blocks 22 corresponds to the number of outer arc plates 21. There are at least four supporting members 3. In the present application, there are four outer arc plates 21 and four connecting blocks 22, and twelve supporting members 3, and one outer arc plate 21 corresponds to at least two supporting members 3.

[0040] Combination Figure 3 and Figure 4 , Figure 3 The structure diagram of the outer arc plate 21 of the utility model, the outer arc plate 21 of the present application comprises a receiving portion 211 and an arc plate portion 212, the outer arc surface of the arc plate portion 212 is used to achieve circumferential fit and support with the inner wall of the external cylinder, and the receiving portion 211 is arranged on the arc plate portion 212. The receiving portion 211 is provided with a receiving groove 2111 with an opening toward the inner ring plate 1, the support member 3 extends into the receiving groove 2111, and abuts against the inner groove bottom of the receiving groove 2111. The accommodating groove 2111 has an inner groove bottom and two opposite inner side walls. The inner groove bottom is on the inner bottom surface of the accommodating groove 2111. The accommodating groove 2111 on the accommodating portion 211 provides a supporting position for the support member 3 to abut against the outer arc plate 21, thereby improving the strength of the outer arc plate 21. The two opposite inner side walls of the accommodating groove 2111 can limit the position of the support member 3 supporting the outer arc plate 21, so that the support member 3 can extend into the accommodating groove 2111 one by one and realize the support of the arc plate portion 212.

[0041] In fact, the receiving portion 211 can be a channel steel, on which a receiving groove 2111 is formed, the inner bottom surface of the receiving groove 2111 is a plane, and the inner bottom surface of the receiving groove 2111 is perpendicular to the radial direction of the inner ring plate 1, so that the support member 3 can apply abutting force to the outer arc plate 21. The outer arc plate 21 can be provided with one or more receiving grooves 2111.

[0042] Further, combined with Figure 3 , Figure 4 and Figure 6The arc plate portion 212 includes an annular sealing plate 2123 and two arc plates 2121 arranged relatively at intervals. The annular sealing plate 2123 faces the inner ring plate 1 and the outer arc surface of the annular sealing plate 2123 is used to fit with the inner wall of the cylinder. The two arc plates 2121 are connected to the two opposite arc edges of the annular sealing plate 2123 along the axial direction. The accommodating portion 211 is arranged on the inner arc surface of the annular sealing plate 2123. The accommodating groove 2111 extends along the axial direction of the inner ring plate 1, and the two arc plates 2121 cover the axial openings on both sides of the accommodating groove 2111. The annular sealing plate 2123 has an outer arc surface that can be circumferentially fitted with the inner wall of the cylinder. The accommodating portion 211 is arranged on the inner arc surface of the annular sealing plate 2123. Two relatively spaced arc plates 2121 are respectively vertically arranged on the two side arc edges of the annular sealing plate 2123, and the two arc plates 2121 seal the two end openings of the accommodating groove 2111 along the axial direction. The two arc plates 2121 further limit the supporting position of the support member 3 to the outer arc plate 21, which is convenient for the alignment installation of the outer arc plate 21 and can also reduce the misalignment of the support member 3.

[0043] The annular sealing plate 2123 and the two arc-shaped plates 2121 can be fixed by welding, and the accommodating portion 211 can also be fixed on the annular sealing plate 2123 by welding.

[0044] In some other embodiments, the arc plate portion may also only include the annular sealing plate 2131 , and the accommodating portion 211 is arranged on the inner arc surface of the annular sealing plate 2123 .

[0045] In this embodiment, a plurality of first ribs 2122 are connected between the two arc plates 2121, and the plurality of first ribs 2122 are arranged at intervals along the extension direction of the arc plates 2121. The first ribs 2122 support the two arc plates 2121, improve the overall strength and stability of the outer arc plate 21, and reduce deformation.

[0046] The first rib plate 2122 can be welded and fixed between the two arc plates 2121. In this embodiment, two accommodating grooves 2111 are provided on an outer arc plate 21 to improve the support stability and force uniformity of the outer arc plate 21. In addition, five first rib plates 2122 are provided on an outer arc plate 21, and two adjacent first rib plates 2122 are arranged on both sides of the accommodating groove 2111, and first rib plates 2122 are provided at both ends of the annular sealing plate 2123 and the two arc plates 2121 to improve the structural stability of the outer arc plate 21 and improve the strength of the outer arc plate 21. In fact, the annular sealing plate 2123, the two arc plates 2121 and the five first rib plates 2122 are formed as a whole by group welding.

[0047] Combination Figure 5One of the connection block 22 and the outer arc plate 21 is provided with an adjustment hole 222, and the other is provided with a connection hole 221. The adjustment hole 222 is waist-shaped. The connection block 22 and the outer arc plate 21 are connected by a pin 223, and the pin 223 can move in the adjustment hole 222. The pin 223 is inserted into the adjustment hole 222 and the connection hole 221 at the same time to realize the connection between the connection block 22 and the outer arc plate 21. Corresponding to the two adjustment holes 222 on the same connection block 22, the two adjustment holes 222 extend in a direction close to each other.

[0048] Specifically, the two outer arc plates 21 are respectively arranged on opposite sides of the connection block 22, the adjustment hole 222 is arranged on one of the connection block 22 and the outer arc plate 21, and the connection hole 221 is arranged on the other, and the adjustment hole 222 is directly opposite to the connection hole 221, and the adjustment hole 222 is a waist-shaped hole, and the pin 223 penetrates into the adjustment hole 222 and the connection hole 221. When the length of the outer arc plate 21 is extended or retracted, the pin 223 can slide in the adjustment hole 222, so that the outer arc plate 21 can slide relatively along the connection block 22 and can form a certain angle of rotation, which is convenient for adjusting the position of the outer arc plate 21 and convenient for installation. In addition, the two adjustment holes 222 for connection corresponding to the same connection block 22 extend in the direction of approaching each other, so that the two adjacent outer arc plates 21 can move in the direction of approaching or moving away from each other, thereby reducing or increasing the overall outer diameter of the outer support plate 2. The pin shaft 223 of the present application extends along the axial direction of the inner ring plate 1, thereby reducing the deviation and misalignment of the two ends of the outer arc plate 21 along the axial direction of the external cylinder.

[0049] In the present application, the perpendicular midline of the center connection line of the two adjustment holes 222 on the same connection block 22 extends radially along the inner ring plate 1. Specifically, the two adjustment holes 222 on the connection block 22, or the adjustment holes 222 on the two outer arc plates 21 corresponding to the same connection block 22, are radially symmetrical to the inner ring plate 1, and the perpendicular midline of the center connection line of the two adjustment holes 222 passes through the axis of the inner ring plate 1, further reducing the misalignment of the adjacent outer arc plates 21 during the position adjustment process. In addition, in this embodiment, the extension direction of the two adjustment holes 222 corresponding to the same connection block 22 is located on the same straight line, so that the movement trajectory of the adjacent two outer arc plates 21 during the movement process is on the same straight line, further reducing the radial misalignment of the adjacent outer arc plates 21 during the adjustment process, ensuring the roundness of the outer support plate 2, and reducing the protrusion of the end of the outer arc plate 21. In some embodiments, the connection block 22 is recessed between the two adjacent outer arc plates 21 to prevent the outer support plate 2 from protruding at the position corresponding to the connection block 22, thereby ensuring the roundness of the outer support plate 2.

[0050] In addition, the two adjustment holes 222 corresponding to the same connection block 22 may also extend obliquely in opposite directions toward or away from the inner ring plate 1 , or the two adjustment holes 222 may extend in an arc shape along the circumferential direction of the outer support plate 2 .

[0051] Reference Figure 3 , Figure 4 and Figure 6 , Figure 6 2 is an exploded view of the connection structure of the outer arc plate 21 and the connection block 22. In this embodiment, the two ends of the outer arc plate 21 are provided with connection holes 221, and the two opposite sides of the connection block 22 are respectively provided with adjustment holes 222. In fact, the connection holes 221 are set on the arc plate 2121. In other embodiments, the two ends of the outer arc plate 21 can also be provided with adjustment holes 222, and the connection block 22 can be provided with connection holes 221. Alternatively, one end of the outer arc plate 21 is provided with an adjustment hole 222, and the other end is provided with a connection hole 221, and the connection block 22 is provided with a connection hole 221 corresponding to the position where the adjustment hole 222 is set on the outer arc plate 21, and the connection block 22 is provided with an adjustment hole 222 corresponding to the position where the connection hole 221 is set on the outer arc plate 21.

[0052] Moreover, a limit block with a width greater than the outer diameter of the pin 223 is formed at one end of the pin 223, and the limit block can be stuck in one side of the connecting hole 221 or the adjusting hole 222. A limit rod is passed through the other end of the pin 223 to limit the axial movement of the pin 223 and prevent the pin 223 from falling off from the connecting hole 221 and the adjusting hole 222. When the pin 223 needs to be disassembled, the limit rod is pulled out to pull the pin 223 out from the side with the limit block.

[0053] Moreover, combined with Figure 5 The connection block 22 is provided with a bottom plane 224 perpendicular to the radial direction of the inner ring plate 1, and the extension direction of the support member 3 is perpendicular to the bottom plane 224. The support member 3 can extend along the radial direction of the inner ring plate 1 and abut vertically on the bottom plane 224 of the connection block 22, so that the abutting force of the support member 3 can directly act on the connection block 22, while reducing the support member 3 obliquely pressing on the connection block 22, resulting in insufficient support force, or even misalignment and falling off.

[0054] Combination Figure 6 It can be seen that the connection block 22 includes two mounting grooves 225 with openings facing away from each other, and the adjustment hole 222 or the connection hole 221 on the connection block 22 passes through the connection block 22 along the axial direction of the inner ring plate 1, and communicates with the mounting groove 225; the outer arc plates 21 arranged on opposite sides of the connection block 22 are respectively accommodated in the mounting grooves 225, and the pin 223 passes through the mounting grooves 225. Specifically, the end of the outer arc plate 21 is embedded in the mounting groove 225 of the connection block 22, the pin 223 passes through the outer arc plate 21, and the two ends of the pin 223 pass through the connection block 22 in sequence. For one outer arc plate 21, the connection block 22 provides two supporting force positions on both sides of the axial direction of the outer arc plate 21, ensuring that the connection block 22 is evenly stressed and improving the structural stability of the connection block 22.

[0055] Specifically in this embodiment, the connection block 22 includes two connection plates arranged in parallel and spaced apart and a web plate vertically connected to the middle of the connection plates. The connection plates are divided into a left connection plate and a right connection plate by the web plate as a boundary, and the two left connection plates and the web plate enclose one installation groove 225, and the two right connection plates and the web plate enclose another installation groove 225.

[0056] Reference Figure 1 The support member 3 includes a first support member 313 and a second support member 323. The end of the first support member 313 away from the inner ring plate 1 abuts against the outer arc plate 21, and the end of the second support member 323 away from the inner ring plate 1 abuts against the connecting block 22. The first support member 313 is used to support the outer arc plate 21 and plays a main supporting role. The second support member 323 is used to support the connecting block 22 and plays an auxiliary supporting role to improve the supporting stability of the outer support plate 2. The first support members 313 of the present application are provided with eight, and the second support members 323 are provided with four corresponding to the position of the connecting block 22.

[0057] In fact, the support member 3 may also only include a plurality of first support members 313 capable of supporting the outer arc plate 21 , and the outer diameter adjustment of the outer support plate 2 can also be achieved.

[0058] Reference Figure 7 , Figure 7 for Figure 1 The partial enlarged view of the first support member 313 in the middle, the first support member 313 includes a nut 311, an adjusting bolt 312 and a support rod 313, the nut 311 is fixed on the inner ring plate 1, the adjusting bolt 312 is screwed with the nut 311, one end of the support rod 313 is rotatably connected to the end of the adjusting bolt 312 away from the inner ring plate 1, and the other end of the support rod 313 is abutted against the outer arc plate 21. The nut 311 is fixedly arranged on the inner ring plate 1, and the screw hole on the nut 311 extends along the radial direction of the inner ring plate 1. By rotating the adjusting bolt 312, the adjusting bolt 312 drives the support rod 313 to move toward or away from the outer support plate 2 relative to the nut 311, so as to realize the expansion and contraction of the first support member 313, which can effectively prevent the adjusting bolt 312 from shaking during the rotation process, and effectively prevent the adjusting bolt 312 from bending due to the normal force when supporting the thick wall cylinder, so as to avoid the damage of the adjusting bolt 312.

[0059] The nut 311 can be fixed on the inner ring plate 1 by welding, and the adjusting bolt 312 can realize radial movement relative to the inner ring plate 1, thereby driving the support rod 313 to expand and contract, so that the radius of the outer support plate 2 can increase or decrease with the expansion and contraction of the support rod 313, which is convenient for adjustment. The support rod 313 can only abut against the receiving groove 2111 of the outer arc plate 21, or the support rod 313 and the outer arc plate 21 are relatively fixed by welding or other means, so that when the support rod 313 abuts against the outer arc plate 21, during the process of rotating the adjusting bolt 312, the support rod 313 is prevented from rotating with the adjusting bolt 312, and wear is prevented at the position where the support rod 313 abuts against the outer arc plate 21.

[0060] Furthermore, the first support member 313 includes a baffle 314, which is fixedly arranged on the inner ring plate 1, and is provided with an avoidance hole 3141. The end of the adjusting bolt 312 facing away from the support rod 313 is directly opposite to the avoidance hole 3141, and the end of the adjusting bolt 312 facing away from the support rod 313 is provided with an anti-rotation structure 3121 for pairing with a wrench 4.

[0061] Specifically, the baffle 314 and the nut 311 are arranged on the inner ring plate 1 at intervals and clamped between two opposite ring-shaped plates 11, thereby improving the structural strength of the inner ring plate 1 and also improving the installation stability of the baffle 314 and the nut 311. Fig. 9 The avoidance through hole 3141 can be used to insert the socket wrench 4 hands and put it on the anti-rotation structure 3121 to rotate, so that the adjusting bolt 312 is driven by the anti-rotation structure 3121 to rotate, and the position of the outer arc plate 21 can be adjusted. In fact, the anti-rotation structure 3121 can be a prism structure such as a square, pentagon or hexagon, which can cooperate with the wrench with a socket to achieve torsion. Moreover, the avoidance through hole 3141 is designed to be slightly larger than the socket wrench 4 hands used by the anti-rotation structure 3121 by 1mm to 2mm.

[0062] And, combined with Figure 2 and Figure 7 The first support member 313 includes a second rib plate 315, and the second rib plate 315 is connected between the nut 311 and the baffle plate 314. The second rib plate 315 connects the nut 311 and the baffle plate 314, so that the installation of the nut 311 and the baffle plate 314 is more stable. At the same time, the second rib plate 315 is arranged between the two opposite ring-shaped plates 11, which can further improve the structural strength of the inner ring plate 1. In this embodiment, the second rib plate 315 is arranged on both sides of the nut 311 to improve the structural strength of the support member 3 and the inner ring plate 1.

[0063] Reference Figure 7 and Figure 8The first support member 313 also includes a transition seat 316 and a screw 317. The two opposite end surfaces of the transition seat 316 are provided with a first groove 3161 and a second groove 3162. A through hole is connected between the inner bottom surface of the first groove 3161 and the inner bottom surface of the second groove 3162. The end of the adjusting bolt 312 close to the outer arc plate 21 penetrates into the first groove 3161, and the screw 317 passes through the through hole and is threadedly connected to the adjusting bolt 312. The end surface of the support rod 313 close to the adjusting bolt 312 is provided with an avoidance hole 3131, and the support rod 313 can be detachably inserted into the second groove 3162, and the nut 3171 of the screw 317 is located in the avoidance hole 3131. The transition seat 316 is locked on the adjustment bolt 312 by the screw 317, the support rod 313 is stuck on the second groove 3162 of the transition seat 316, and the nut 3171 of the screw 317 partially extends into the avoidance hole 3131 of the support rod 313, which is convenient for the installation of the support rod 313. When the support rod 313 is pressed against the outer arc plate 21, the support rod 313 can be relatively positioned between the outer arc plate 21 under the action of friction during the rotation of the adjustment bolt 312. The support rod 313 is located between the two relatively arc plates 2121 and inside the accommodating groove 2111 to position the support rod 313. When the adjustment bolt 312 is rotated, the support rod 313 can drive the outer arc plate 21 to move, and the pin 223 can slide freely in the waist-shaped adjustment hole 222, so that the diameter of the annular outer support plate 2 can change freely.

[0064] Reference Figure 5 The second support member 323 is connected between the inner ring plate 1 and the connecting block 22. The second support member 323 includes a nut 311, an adjusting bolt 312 and a transition seat 316. The nut 311 is fixed on the inner ring plate 1. The adjusting bolt 312 is screwed to the nut 311. The transition seat 316 is rotatably connected to one end of the adjusting bolt 312 away from the inner ring plate 1, and the other end of the transition seat 316 abuts against the connecting block 22. The adjusting bolt 312 extends radially along the inner ring plate 1. The nut 311 has a screw hole extending radially along the inner ring plate 1. By twisting the adjusting bolt 312, the adjusting bolt 312 moves back and forth along the screw hole of the nut 311, thereby driving the transition seat 316 to abut against the connecting block 22 or retreat from the connecting block 22, reducing the shaking of the adjusting bolt 312 during the rotation process and improving stability. By connecting the second support member 323 with a retractable length between the inner ring plate 1 and the connecting block 22, a better support effect can be provided for the outer support plate 2, which is suitable for the situation where a thicker cylinder needs to be rounded. In addition, the adjusting bolt 312 extends radially along the inner ring plate 1, so that the adjusting bolt 312 can act vertically on the outer arc plate 21, effectively preventing the normal deformation caused by the force offset of the adjusting bolt 312.

[0065] In actual use, the cylinder can be placed on the ground in a horizontal form, that is, the axial direction of the cylinder extends horizontally. Before installation, the nut 311, baffle 314 and second rib plate 315 on the support are welded and fixed to the inner ring plate symmetrically along the center. During the installation process, the outer arc plate 21 and the connecting block 22 located on the lower side are first placed in the corresponding installation position on the inner wall of the cylinder, and then the inner ring plate 1 is placed in the cylinder, and the adjusting bolt 312 is threaded into the nut 311, and the end of the adjusting bolt 312 with the support rod 313 is inserted into the receiving groove 2111 of the lower outer arc plate 21, and then the inner ring is connected to the lower outer arc plate 21 and the connecting block 22. Block 22, then rotate the adjusting bolt 312 to adjust the overall length of the support 3, so that the inner ring plate 1 is adjusted to a suitable center height. At this time, the axial direction of the inner ring plate 1 extends horizontally, and then the outer arc plate 21 on the upper side is installed through the support 3, and the outer arc surface of the upper outer arc plate 21 is pressed against the side wall of the cylinder, and then the remaining outer arc plates 21 are installed on the device to form a ring-shaped outer support plate 2. Finally, the diameter of the outer support plate 2 is measured, and the length of each support 3 is adjusted to make the overall diameter of the outer support plate 2 meet the requirements.

[0066] When supporting cylinder structures of different sizes, the staff can replace the outer arc plates 21 with different curvatures and adjust the overall length of the support member 3 accordingly, so that the outer arc surface of the outer arc plate 21 can always fit together with the inner wall of the cylinder of the matching size.
