Description

Technical Field

[0001] This invention relates to a horizontal assembly device and method for ultra-long rotating body sections, and to an assembly process and equipment for bonding and gluing metal shells and heat-resistant sleeves for ultra-long (over 5m) rotating body sections. The metal shell is a single integral structure, while the heat-resistant sleeve is a segmented spliced ​​structure. This invention belongs to the field of composite material section assembly technology. Specifically, it discloses a horizontal assembly device and method for ultra-long rotating body sections, which can achieve flexible and stable horizontal assembly and pressurization of ultra-long metal shells and heat-resistant sleeves. Background Technology

[0002] The spacecraft employs a structure where a metal shell is fitted with multiple segmented heat shields. The heat shields have a larger diameter than the metal shell and are fitted onto its outer surface. The manufacturing process involves applying adhesive to the inner surface of the heat shields, then sequentially fitting multiple heat shields onto the outer surface of the metal shell, applying pressure and curing, and finally releasing the pressure after the adhesive has completely cured. For ultra-long (over 5m) rotating sections, due to their excessive length (over 5m), if a traditional vertical fitting method is used, it requires manual labor at a height of over 5m to sequentially fit the heat shields onto the outer surface of the metal shell. After the last heat shield is fitted, a pressure plate is used with the aid of a pull rod to press the heat shield end face downwards until it is flush with the metal shell. This process involves high-altitude operations, has a low safety factor, and the excessively long pull rod is prone to instability. Furthermore, the excessive tension can damage the heat shield end face in contact with the pressure plate. Summary of the Invention

[0003] The technical problem solved by this invention is to overcome the shortcomings of the prior art and provide a horizontal assembly device and assembly method suitable for ultra-long rotating body sections. The separate bracket can both support the metal shell and allow the heat-resistant sleeve to be fitted into the metal shell; the segmented pressure plate can be flexibly positioned on any end face of the heat-resistant sleeve, and can pressurize a single heat-resistant sleeve.

[0004] The technical solution of the present invention is: Firstly, a horizontal assembly device suitable for ultra-long rotating body sections, comprising:

[0005] The fixed base includes a main truss base, a front fixed upright, an upright adapter block, a front connecting plate, rollers, a spiral adjusting support rod, and a strut adapter seat. The rollers are fixedly connected to the bottom surface of the main truss base, allowing the fixed base to move freely on the ground. A strut adapter seat is fixedly connected to the side of the main truss base, and the spiral adjusting support rod is screwed into the strut adapter seat. Adjusting the spiral strut supports the fixed base, fixing it to the ground. The front fixed upright is fixedly connected to the front end of the fixed base, and the upright adapter block is fixedly connected to the fixed base.

[0006] The detachable bracket has several parallel arrangement components. Each detachable bracket includes a tray, a slide rail, an insert, and a profile bracket. The tray is fixedly connected to a fixed base, the slide rail is fixedly connected to the tray, and the insert is fixedly connected to the profile bracket. The insert drives the profile bracket to move on the slide rail, realizing the closing and opening of a set of profile brackets. The rotating section is placed on the profile bracket, and the bottom of the metal part of the rotating section is fixedly connected to the front connecting plate.

[0007] The split tensioning disc is used to press the heat-resistant sleeve on the outside of the metal part of the rotating body section. It includes an upper disc, a lower disc, and a tensioning band. The upper and lower discs are connected and merged into a complete disc. The tensioning band passes through the upper disc, the lower disc, and the front connecting disc to tighten the heat-resistant sleeve.

[0008] Furthermore, the number of the separate brackets is determined based on the number and size of the heat-resistant sleeve segments, to avoid interference with the heat-resistant sleeve during assembly.

[0009] Furthermore, the front connecting plate is provided with a hole for fixed connection with the bottom of the metal part of the rotating body section, and the hole position is aligned with the hole position at the bottom of the metal part of the rotating body section.

[0010] Furthermore, the front connecting plate is connected to the upright adapter block via an elongated hole and bolts, and the elongated hole is used to adjust the position of the front connecting plate.

[0011] Furthermore, both ends of the tray are provided with limiting blocks, which are used to limit the sliding movement of the conforming bracket driven by the insert blocks.

[0012] Furthermore, a locking device is provided on the inner side of the tray to fix the template when the insert moves the template into place.

[0013] Furthermore, the length of the rotating section is not less than 5 meters.

[0014] Secondly, a method for assembling a horizontal assembly device suitable for ultra-long rotating body sections, as described above, includes:

[0015] Step (1): Push the kit to the preset assembly station;

[0016] Step (2): Fix the front connecting plate to the metal shell to be fitted, pass the sling through the metal shell to be fitted, and use the sling to lift the metal shell to be fitted together with the front connecting plate and place it on the template bracket. After the metal shell is stably placed on the template bracket, insert the bolt into the elongated hole of the front connecting plate and the upright adapter block to fix the two together.

[0017] Step (3): Apply adhesive to the inner surface of the first heat protection sleeve and put the first heat protection sleeve into the open end of the metal shell to be fitted. When it encounters the first split bracket, push the molded bracket of the split bracket to both sides along the slide rail to separate the two molded brackets so that the first heat protection sleeve can pass through. Continue to push the heat protection sleeve forward. When it encounters the second split bracket, after closing the first split bracket, open the second split bracket. Repeat the operation in this way until the first heat protection sleeve is pushed to the end.

[0018] Step (4): Install the upper half plate and the lower half plate at the end face of the first heat protection sleeve, and fix them together. Connect the upper half plate, the lower half plate and the front connecting plate together with the tensioning strap. By continuously tightening the tensioning strap, the upper half plate and the lower half plate will move closer to the front connecting plate, thereby pushing the first heat protection sleeve closer to the end of the metal shell to be fitted until it is flush with the end face. The pressure is maintained by the split tensioning plate until the adhesive of the first heat protection sleeve is cured and the first heat protection sleeve no longer moves. Remove the split tensioning plate.

[0019] Repeat steps (3) and (4) until all heat protection suits are fitted.

[0020] Furthermore, the closing of the first separate bracket includes: when the insert drives the profile bracket to slide into place, the bolt installed at the bottom of the profile bracket is screwed onto the slide rail to fix the profile bracket.

[0021] Furthermore, the assembly is pushed to the preset assembly position, and the screw is turned to adjust the support rod so that it is lowered until it presses against the ground, ensuring that the assembly is fixed in place.

[0022] The advantages of this invention compared to the prior art are:

[0023] (1) This invention enables the horizontal assembly of ultra-long (over 5m) rotating sections, avoiding the risks associated with manual high-altitude operations required for vertical assembly. This invention employs three sets of separate brackets. When the heat shield is fitted, two sets of brackets close to support the metal shell, while one set of separate brackets opens to facilitate the smooth passage of the heat shield. A similar method can be used to achieve horizontal fitting of the heat shield.

[0024] (2) Existing vertical assembly methods involve inserting all heat shields and then using an end face plate to pressurize all heat shields into place at once. This method is not suitable for extra-long sections because there are many heat shields in extra-long sections, and the frictional force from pressing at once is large. The pressure of the end face plate must be greater than the frictional force to move the heat shields to one end. Excessive pressure from the end face plate acting directly on the heat shields can easily cause damage. To address this, the present invention proposes a segmented tensioning plate, which is assembled into a whole plate at the initial position of each heat shield segment. This allows for individual pressurization of each heat shield segment, avoiding damage caused by excessive pressure.

[0025] (3) Existing technologies use a tie rod in conjunction with an end face plate to pressurize the heat-resistant sleeve. Different sized tie rods need to be prepared for different sized sections, resulting in limited applicability of the device. This invention uses a tension band instead of a tie rod, making it applicable to sections with a length smaller than the tension band, thus broadening its applicability. Attached Figure Description

[0031] To better understand the above technical solutions, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present invention, rather than limitations on the technical solutions of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0032] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a horizontal assembly device and assembly method for extra-long rotating body sections provided by embodiments of the present invention.

[0033] In the solutions provided in the embodiments of the present invention, such as Figure 1 A horizontal assembly suitable for extra-long rotating body sections includes a fixed base 1, a first separate bracket 2, a second separate bracket 3, a third separate bracket 4, and a split tensioning plate 5.

[0034] like Figure 2The fixed base 1 is equipped with rollers at its bottom, allowing it to move freely on the ground. It includes a main truss base 6, a front fixed support 7, a support adapter block 8, a front connecting plate 9, rollers 10, a spiral adjusting support rod 11, and a strut adapter seat 12. The rollers 10 are bolted to the bottom surface of the main truss base 6, enabling the fixed base 1 to move freely on the ground. The strut adapter seat 12 is bolted to the side of the main truss base 6, and the spiral adjusting support rod 11 is screwed into the strut adapter seat 12. Adjusting the spiral strut 11 can raise the fixed base 1 and fix it to the ground. The front fixed support 7 is bolted to the front end of the fixed base 1, the support adapter block 8 is bolted to the fixed base 1, and the front connecting plate 9 is bolted to the support adapter block 8 through an elongated hole. The elongated hole allows for flexible adjustment of the position of the front connecting plate 9.

[0035] like Figure 3 The first separate bracket 2, the second separate bracket 3, and the third separate bracket 4 have the same structure. Taking the first separate bracket 2 as an example, it is described as follows: The first separate bracket 2 is fixedly connected to the fixed base 1 by bolts. It includes a support plate 13, a slide rail 14, an insert 15, and a contour bracket 16. The support plate 13 is fixedly connected to the fixed base 1 by bolts, the slide rail 14 is fixedly connected to the support plate 13 by bolts, and the insert 15 is fixedly connected to the contour bracket 16 by bolts. The insert 15 can drive the contour bracket 16 to move on the slide rail 14, realizing the closing and opening of a set of contour brackets 16.

[0036] like Figure 4 The split tensioning disc 5 is used to tighten the heat shield, and it includes an upper disc 17, a lower disc 18, and a tensioning band 19. The upper disc 17 and the lower disc 18 are connected by bolts to form a complete disc, and the tensioning band 19 passes through the upper disc 17, the lower disc 18, and the front connecting disc 9 to tighten the heat shield.

[0037] The number of separate brackets is determined based on the number and size of the heat shield segments, and interference with the heat shield should be avoided when fitting them together.

[0038] The front connecting plate has holes for fixed connection with the bottom of the metal part of the rotating body section, and the holes are aligned with the holes on the bottom of the metal part of the rotating body section. The front connecting plate is connected to the upright adapter block via elongated holes and bolts. The elongated holes are used to adjust the position of the front connecting plate. Both ends of the support plate are equipped with limit blocks for limiting the sliding movement of the guide bracket driven by the insert block. The inner side of the support plate is equipped with a locking device to fix the guide bracket when it slides into place.

[0039] The device method based on the aforementioned horizontal assembly device suitable for ultra-long rotating body sections includes the following steps:

[0040] (1) Push the assembly unit to the assembly station, turn the screw to adjust the support rod 11 so that it slowly descends until it presses against the ground, and ensure that the assembly unit is fixed in place.

[0041] (2) Fix the front connecting plate 9 to the metal shell to be assembled with bolts, pass the sling through the metal shell, and lift the metal shell together with the front connecting plate 9 onto the molded bracket 16 with the help of the sling. After the metal shell is stably placed on the molded bracket 16, insert the bolt into the elongated hole of the front connecting plate 9 and the upright adapter block 8 to fix the two together.

[0042] (3) Apply glue to the inner surface of the first heat protection sleeve, and put the first heat protection sleeve into the open end of the metal shell. When it encounters the first split bracket 2, push the molded bracket 16 to both sides along the slide rail 14 to separate the two molded brackets so that the heat protection sleeve can pass through. Continue to push the heat protection sleeve forward. When it encounters the second split bracket 3 and the third split bracket 4, repeat the above operation until the first heat protection sleeve is pushed to the end and cannot be pushed by manpower.

[0043] (4) Install the upper half plate 17 and the lower half plate 18 at the end face of the first heat protection sleeve, and connect the two together with bolts. Connect the upper half plate 17, the lower half plate 18 and the front connecting plate 9 together with the tensioning strap. By continuously tightening the tensioning strap, the upper half plate 17 and the lower half plate 18 are driven to move closer to the front connecting plate 9, thereby pushing the first heat protection sleeve to move closer to one end of the metal shell until it is flush with the end face. The pressure is maintained by the split tensioning plate 5 until the adhesive of the first heat protection sleeve is cured and the first heat protection sleeve no longer moves. Remove the split tensioning plate 5.

[0044] (5) Repeat steps (3) and (4) until all heat protection suits are fitted.
