Description

Technical Field

[0001] This invention relates to the field of circular tube truss installation technology, specifically to a circular tube truss installation and positioning device. Background Technology

[0002] In the construction of modern football stadiums, circular tube truss structures are widely used in roofs, grandstand eaves and other parts due to their good mechanical properties and aesthetics. However, football stadiums have a large spatial span, complex structural shape, and often need to be constructed on existing site foundations, which brings great challenges to the installation and positioning of circular tube trusses. In the traditional process of welding web members to a circular tube truss, lifting machinery is typically used in conjunction with manual measurement and adjustment, which results in low positioning accuracy. In addition, when welding and assembling a circular tube truss with web members, it is usually necessary to distribute four circular tubes into a square area, and then weld the web members between two adjacent circular tubes. The traditional positioning method can only position two circular tubes. After the web members between the two positioned circular tubes are welded and installed, the third and fourth circular tubes are then positioned in sequence. The positioning work is cumbersome and cannot simultaneously position all four circular tubes on a single positioning fixture.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a circular tube truss installation and positioning device to solve the problems mentioned in the background art, which require the four circular tubes to be positioned in pairs, resulting in cumbersome positioning work and low positioning accuracy due to the need for hoisting machinery combined with manual measurement and adjustment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A circular tube truss installation and positioning device, comprising: A support unit is located below the circular tube body and is used to support the circular tube body. The support unit includes a bearing plate for laterally pushing two sets of circular tube bodies on one side. The adjustment unit includes a lifting component located at the lower part of the support unit for vertical adjustment of the two sets of lower circular tube bodies, and a bearing component located at the upper part of the support unit for supporting and limiting the two sets of upper circular tube bodies.

[0006] Furthermore, the support unit also includes: Two sets of crossbars are provided in parallel to support and guide the bearing plate; The longitudinal bars are provided in two sets and are fixedly connected between the two sets of transverse bars to form a rectangular area; A push rod is fixedly connected between the two sets of bearing plates, and a first cylinder for pushing the push rod is installed on one side of one of the longitudinal rods; The first bracket is fixedly connected to the upper end of the bearing plate, and a first guide groove is provided through the lower part of the first bracket; The second bracket is fixedly connected to the upper end of the bearing plate and to the side away from the first bracket. A second guide groove is provided through the lower part of the second bracket.

[0007] Furthermore, a slider is fixedly connected to the lower end of the support plate, and the slider is designed as an inverted "T" shape; The upper end of the crossbar is provided with a guide groove for guiding the movement of the slider; The crossbar is provided with a limiting groove inside and outside the slider for limiting the slider's vertical movement.

[0008] Furthermore, the lifting component includes: The support beam has two sets corresponding to the first bracket, one end of which is slidably inserted into the first guide groove, and the other end is slidably inserted into the second guide groove. The lifting rod is fixedly connected to the lower end of the two sets of support beams and is used to drive the support beams to adjust up and down. The lower end of the lifting rod is equipped with a second cylinder for driving the lifting rod to move up and down. The first tray has two fixed connections at the upper end of each set of support beams, which are used to limit the two round tube bodies below.

[0009] Furthermore, a guide shaft is fixedly connected to one side of the support beam; One end of the guide shaft, located inside the support beam, is fixedly connected to a limit block. The support beam has a first retraction groove inside and outside the guide shaft, which is slidably connected to the guide shaft. This groove is used to extend or retract the length of the support beam when the slider moves along the guide groove.

[0010] Furthermore, the carrier component includes: The insert block, at the same height, slides into the upper part of the interior of the first bracket and the second bracket; The lifting plate is slidably inserted into the insert block, and the insert block is provided with a second retraction groove for guiding the lifting plate to move up and down. Two sets of guide rods are fixedly connected between the upper and lower ends of the second retraction groove. The lifting plate has a limiting hole inside and outside the guide rod, which is used to limit the lifting plate in cooperation with the guide rod. A tensioning spring is located at the lower end of the lifting plate and between the two sets of guide rods, and is used to press the lifting plate upward. The second tray is fixedly connected to the upper end of the lifting plate and located inside the first or second bracket, and is used to support and limit the two sets of circular tube bodies above.

[0011] Furthermore, the first bracket and the second bracket are provided with holes for accommodating the insert block; A handle is fixedly connected to the upper end of the insert block and to the side of the first or second bracket opposite to the second tray; A pressure block for pressing and adjusting the lifting plate is fixedly connected to the upper end of the lifting plate near the handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention first places the two upper cylindrical tubes on the corresponding upper support components, and then places the two lower cylindrical tubes on the corresponding lower lifting components, thus supporting and positioning the four cylindrical tubes. When it is necessary to adjust the horizontal spacing between two adjacent sets of cylindrical tubes on the left and right sides, simply moving the support plate will simultaneously adjust the horizontal spacing between the two sets of cylindrical tubes on one side and the two sets on the other side. When it is necessary to adjust the vertical spacing between two sets of cylindrical tubes on the top and bottom, simply lifting the two lower cylindrical tubes simultaneously with the lifting components will adjust the vertical spacing. Once the spacing is adjusted to the desired position, the web members are welded sequentially between the two adjacent cylindrical tubes. This achieves the effect of synchronously positioning and adjusting the four cylindrical tubes, allowing for flexible adjustment of the cylindrical tubes and high assembly accuracy.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-7 The present invention provides a technical solution: A circular tube truss installation and positioning device, comprising: Support unit 1 is located below the circular tube body 100 and is used to support the circular tube body 100. The support unit 1 includes a bearing plate 15 for laterally pushing two sets of circular tube bodies 100 on one side. The adjustment unit 2 includes a lifting component 21 located at the lower part of the support unit 1 for vertical adjustment of the two sets of circular tube bodies 100 below, and a bearing component 22 located at the upper part of the support unit 1 for supporting and limiting the two sets of circular tube bodies 100 above.

[0017] It should be noted that when positioning the four cylindrical tube bodies 100, the two upper cylindrical tube bodies 100 are first placed on the upper corresponding support components 22, and then the two lower cylindrical tube bodies 100 are placed on the lower corresponding lifting components 21, thus completing the support and positioning of the four cylindrical tube bodies 100. When it is necessary to adjust the horizontal spacing between two adjacent sets of cylindrical tube bodies 100 on the left and right sides, it is only necessary to move the support plate 15 to simultaneously move the two sets of cylindrical tube bodies 100 on one side and the two sets of cylindrical tube bodies on the other side. The horizontal spacing of the main body 100 can be adjusted. When it is necessary to adjust the vertical spacing of the two sets of circular tube main bodies 100, the two lower circular tube main bodies 100 can be lifted synchronously by the lifting component 21 to complete the vertical spacing adjustment. When the spacing is adjusted to the required position, the web rods 101 are welded between the two adjacent circular tube main bodies 100 in sequence. This achieves the effect of synchronous positioning and adjustment of four circular tubes, which can flexibly adjust the circular tube main bodies 100 and has high assembly accuracy.

[0018] As an improvement, such as Figure 1-2 As shown, the support unit 1 further includes: Two sets of crossbars 11 are provided in parallel to support and guide the bearing plate 15; The longitudinal bar 12 is provided in two sets and is fixedly connected between the two sets of the transverse bars 11 to form a rectangular area; Push rod 13 is fixedly connected between the two sets of bearing plates 15, and a first cylinder 14 for pushing push rod 13 is installed on one side of one of the longitudinal rods 12. The first bracket 16 is fixedly connected to the upper end of the bearing plate 15, and the first guide groove 161 is provided through the lower part of the first bracket 16; The second bracket 17 is fixedly connected to the upper end of the bearing plate 15 and to the side away from the first bracket 16. The second bracket 17 has a second guide groove 171 extending through its lower part.

[0019] Furthermore, such as Figure 4 As shown, a slider 151 is fixedly connected to the lower end of the support plate 15, and the slider 151 is designed as an inverted "T" shape. The upper end of the crossbar 11 is provided with a guide groove 111 for guiding the movement of the slider 151; The crossbar 11 is provided with a limiting groove 112 inside and outside the slider 151 for limiting the slider 151 to move up and down.

[0020] As an improvement, such as Figure 3 As shown, the lifting assembly 21 includes: The support beam 211 has two sets corresponding to the first bracket 16, one end of which is slidably inserted into the first guide groove 161 and the other end of which is slidably inserted into the second guide groove 171. The lifting rod 212 is fixedly connected to the lower end of the two sets of support beams 211 and is used to drive the support beams 211 to adjust up and down. The lower end of the lifting rod 212 is equipped with a second cylinder 213 for driving the lifting rod 212 to move up and down. The lower end of the second cylinder 213 is provided with a bottom rod 214 for supporting the second cylinder 213. The first tray 215 has two fixed connections at the upper end of each set of support beams 211, which are used to limit the two round tube bodies 100 below.

[0021] Furthermore, such as Figure 5 As shown, a guide shaft 2111 is fixedly connected to one side of the support beam 211; One end of the guide shaft 2111 and inside the support beam 211 is fixedly connected to a limit block 2112; The support beam 211 is provided with a first retraction groove 2113 inside and outside the guide shaft 2111, which is slidably connected to the guide shaft 2111. This groove is used to extend or retract the length of the support beam 211 when the slider 151 moves along the guide groove 111. The support beam 211 has limiting protrusions 2114 on both sides and inside the first guide groove 161. Inside the first guide groove 161 and outside the limiting protrusions 2114, there is a sliding groove 1611 for limiting the movement of the limiting protrusions 2114.

[0022] Furthermore, such as Figure 2 , Figure 6 As shown, the carrier component 22 includes: Insert 221 is slidably inserted at the same height into the upper part of the interior of the first bracket 16 and the second bracket 17; The lifting plate 222 is slidably inserted into the insert block 221. The insert block 221 is provided with a second retraction groove 2212 for guiding the lifting plate 222 to move up and down. The guide rod 223 is provided in two sets and is fixedly connected between the upper and lower ends of the second retraction groove 2212. The lifting plate 222 is provided with a limiting hole 2213 inside and outside the guide rod 223, which is used to cooperate with the guide rod 223 to limit the lifting plate 222. A pressing spring 224 is provided at the lower end of the lifting plate 222 and between the two sets of guide rods 223, and is used to press the lifting plate 222 upward. The insert block 221 is provided with a receiving groove 2214 for accommodating the pressing spring 224 inside and at the lower end of the pressing spring 224. The second tray 225 is fixedly connected to the upper end of the lifting plate 222 and located inside the first bracket 16 or the second bracket 17. It is used to support and limit the two sets of circular tube bodies 100 above. The upper ends of the second tray 225 and the first tray 215 are provided with arc-shaped grooves for limiting the circular tube bodies 100. The arc-shaped groove at the upper end of the second tray 225 and the arc-shaped groove at the upper end of the first tray 215 are located on the same vertical plane.

[0023] The first bracket 16 and the second bracket 17 are provided with holes for accommodating the insert block 221. A handle 2211 is fixedly connected to the upper end of the insert 221 and to the side of the first bracket 16 or the second bracket 17 opposite to the second tray 225. A pressure block 226 for pressing and adjusting the lifting plate 222 is fixedly connected to the upper end of the lifting plate 222 near the handle 2211.

[0024] It should be noted that: in the specific implementation process of this invention, such as Figure 1-2 As shown, the two upper cylindrical tube bodies 100 are placed on the corresponding second trays 225, keeping the two ends of the cylindrical tube bodies 100 aligned. The second trays 225 limit the cylindrical tube bodies 100 through the arc-shaped groove at the upper end. Then, the two lower cylindrical tube bodies 100 are placed inside the corresponding first trays 215, keeping the two ends of the lower cylindrical tube bodies 100 aligned. The arc-shaped groove at the upper end of the first trays 215 limits the lower cylindrical tube bodies 100, thus completing the positioning of the four cylindrical tubes. The positioning work is simple and quick, and can position four cylindrical tubes at the same time, improving the assembly efficiency. like Figure 2-3 As shown, if it is necessary to reduce the vertical distance between the upper and lower circular tube bodies 100, the second cylinder 213 is activated. The second cylinder 213 drives the support beam 211 near both ends to move upward along the inside of the first guide groove 161 and the second guide groove 171 through the lifting rod 212. The support beam 211 drives the two lower circular tube bodies 100 to move upward through the first tray 215, while the two upper circular tube bodies 100 remain stationary, thus completing the adjustment of the vertical distance between the upper and lower circular tube bodies 100. like Figure 4-5As shown, if it is necessary to reduce the horizontal distance between the two corresponding round tube bodies 100 on the left and right sides, the first cylinder 14 is activated. The first cylinder 14 drives the bearing plate 15 to move along the guide groove 111 under the action of the slider 151 through the push rod 13. The bearing plate 15 drives the limiting protrusion 2114 to move through the first bracket 16. The limiting protrusion 2114 drives the support beam 211 to gradually retract. During this process, the limiting block 2112 slides relative to the first retraction groove 2113, the second bracket 17 remains stationary, and the two round tube bodies 100 on the side closer to the first bracket 16 move towards the two round tube bodies 100 on the side closer to the second bracket 17, thereby completing the adjustment of the horizontal distance between the two corresponding round tubes on the left and right sides, thereby improving the welding accuracy of the subsequent web member 101 between the round tubes. like Figure 6-7 As shown, after the four round tubes are positioned and their positions are adjusted, the web members 101 are welded to the round tubes. After the web members 101 are welded, the welded truss is pre-lifted by a crane, so that the round tube body 100 is separated from the second tray 225 and the first tray 215. At this time, the handle 2211 is held and the pressure block 226 is pushed down. The pressure block 226 drives the lifting plate 222 to move down along the second retraction groove 2212, so that the top spring 224 is further compressed and the second tray 225 is completely inserted into the second retraction groove 2212. The insertion block 221 is pulled out along the first bracket 16 or the second bracket 17. Then, the truss is completely lifted out of the area between the first bracket 16 and the second bracket 17 by a crane to avoid the insertion block 221 from obstructing the process of lifting out.
