Description

Technical Field

[0001] This invention relates to a split-type adjustable arc-shaped support device, belonging to the field of special coating molding technology for solid rocket engines. Background Technology

[0002] During the research and development and production of engines, with the changes in the external working environment, aircraft with deep-sea submarine-launched and penetration capabilities have put forward new and higher requirements for automated logistics transfer and product storage in the mass production and automated operation mode.

[0003] Existing split-type, single-diameter arc-shaped support bases can only accommodate aircraft models with a single diameter, failing to meet the needs of automated logistics transfers such as AGVs, exhibiting poor adaptability. With increasing production demands, the types of aircraft products have increased from a dozen to nearly a hundred, leading to a growing demand for arc-shaped support bases with varying diameters. Existing split-type fixed arc-shaped support bases have a limited adaptability range for different diameters and cannot achieve quick adjustments.

[0004] Split-type, single-diameter arc-shaped support bases are not suitable for automated logistics transfer models: the original arc-shaped support devices require manual pushing and lifting, which poses significant safety risks and consumes a large amount of human resources. They cannot effectively cooperate with logistics equipment such as AGVs to achieve automated, efficient transfer and flexible production.

[0005] Existing technologies have shortcomings such as being split-type, having a single diameter arc-shaped support base with limited functionality, and being unsafe. Summary of the Invention

[0006] The technical problem solved by the present invention is to overcome the shortcomings of the prior art and provide a split-type adjustable arc-shaped support device, which solves the problems of low production efficiency and low flexibility caused by personnel-moving support devices.

[0007] The technical solution of this invention is:

[0008] A split-type adjustable arc-shaped support device includes: a gantry, a main arc-shaped support assembly, and a secondary arc-shaped support assembly;

[0009] The gantry is equipped with guide rails along its length. The main arc-shaped support assembly and the secondary arc-shaped support assembly are respectively installed on the guide rails above the gantry and can move within a certain range along the guide rails, thereby enabling the main arc-shaped support assembly and the secondary arc-shaped support assembly to open or retract radially along the engine. The main arc-shaped support assembly and the secondary arc-shaped support assembly together support the external engine housing section. The bottom of the gantry is equipped with a guide pin for docking and positioning with the AGV, which is used for docking with the external automated logistics vehicle.

[0010] Furthermore, the main arc-shaped support assembly and the secondary arc-shaped support assembly have the same structure, both including: an arc-shaped support frame and an auxiliary support;

[0011] The arc surface of the arc support frame is covered with a felt pad, and the arc surface of the auxiliary support is also covered with a felt pad. The auxiliary support is used to compensate for the arc of a certain diameter, and to meet the arc support and positioning of different diameter shell sections. When the auxiliary support is needed, it is installed at the upper end of the arc surface of the arc support frame through the reserved positioning slot hole to meet the fixed support of the small diameter engine shell and avoid the unstable rolling state of the gap on both sides of the engine shell.

[0012] Furthermore, both the curved support frame and the auxiliary support are made of steel.

[0013] Furthermore, the arc-shaped support frame is fixed on the linear guide rail on the gantry and can be moved manually. The bottom four corners of the arc-shaped support frame are provided with through holes, and the guide rail is provided with multiple positioning pin holes corresponding to the through holes on the four corners of the arc-shaped support frame.

[0014] Furthermore, the main arc-shaped support assembly and the secondary arc-shaped support assembly also include positioning locking pins for positioning and locking the main arc-shaped support assembly and the secondary arc-shaped support assembly after they have moved into place on the gantry linear guide rail.

[0015] Furthermore, the positioning locking pin is a retractable positioning pin.

[0016] Furthermore, a trapezoidal positioning block is installed at the center of the bottom of the gantry to cooperate with the lifting logistics vehicle. A trapezoidal groove of matching size is opened in the center of the lifting plate of the logistics vehicle for precise positioning and to ensure the stability of logistics transfer.

[0017] Furthermore, by placing two or more support devices in parallel alignment, the spacing and position of the main arc-shaped support assembly and the secondary arc-shaped support assembly are adjusted to be consistent, supporting both ends or the middle section of the engine.

[0018] Furthermore, the support device has an adjustable arc shape, adapting to the support and transport of various cylindrical or near-cylindrical engines.

[0019] Furthermore, the support device is adapted to engine housings with a diameter of 1500mm-2000mm.

[0020] The advantages of this invention compared to the prior art are:

[0021] (1) This invention fulfills the requirement for automatic engine transfer. The split-type adjustable arc-shaped support device can accommodate housings with diameters of 1500mm-2000mm. It meets the support, positioning, and transportation needs of various existing engine models. The arc-shaped support is positioned using retractable positioning pins.

[0022] (2) This invention achieves universal engine transfer requirements. The gantry structure is well-suited for transfer equipment such as automated logistics vehicles, AGVs, and RGVs, and can be used in automated logistics equipment of a certain size range. The main body is lightweight and has a large load-bearing capacity, meeting the rapid transfer requirements of automated logistics AGVs. The arc-shaped adjustable support method is suitable for supporting and transferring various cylindrical or near-cylinder engines.

[0023] (3) This invention meets the requirements for lightweight engine transport. The split-type movable support device is small in size, occupies little space, and its split structure allows for flexible movement, making it easy to store and place. It can be compactly placed during storage, further improving workstation utilization. Attached Figure Description

[0030] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this invention proposes a split-type adjustable arc-shaped support device, comprising: a gantry 1, a main arc-shaped support assembly 2, and a secondary arc-shaped support assembly 3. Two adjustable arc-shaped support devices or multiple devices can be used in combination.

[0032] The gantry 1 is equipped with guide rails along its length. The main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 are respectively installed on the guide rails above the gantry 1 and can move within a certain range along the guide rails, thereby enabling the main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 to open or retract radially along the engine. The main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 together support the external engine housing section. The bottom of the gantry 1 is equipped with a guide pin for docking and positioning with the AGV, which is used for docking with the external automated logistics vehicle.

[0033] Two masts 1 are placed parallel and aligned on a level ground, with their specific positions determined by the engine operating position. A crane or automated guided vehicle can be used below to adjust the relative position of the two masts 1 to accommodate engines of different lengths. The main and auxiliary arc-shaped support assemblies can be manually adjusted to accommodate engines of different diameters. The main and auxiliary arc-shaped support assemblies are mounted on linear guide rails on the masts and are fixed to the linear guide rails by retractable pins at the four corners of the main and auxiliary arc-shaped supports, allowing for convenient adjustment.

[0034] like Figure 1 and Figure 2 As shown, the main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 have the same structure, both including: an arc-shaped support frame 4 and an auxiliary support 5; the arc surface of the arc-shaped support frame 4 is covered with a felt pad, and the arc surface of the auxiliary support 5 is also covered with a felt pad. The auxiliary support 5 is used to compensate for the arc of a certain diameter, satisfying the arc support and positioning of shell sections of different diameters, such as... Figure 3 As shown. When auxiliary support 5 is required, auxiliary support 5 is installed on the upper end of the arc surface of the arc support frame 4 through the reserved positioning slot hole to provide fixed support for the small diameter engine housing and avoid unstable rolling state in the gap on both sides of the engine housing.

[0035] Preferably, both the arc-shaped support frame 4 and the auxiliary support 5 are made of steel.

[0036] The arc-shaped support frame 4 is fixed on the linear guide rail on the gantry 1 and can be moved manually. The bottom four corners of the arc-shaped support frame 4 are provided with through holes, and the guide rail is provided with multiple positioning pin holes corresponding to the through holes on the four corners of the arc-shaped support frame 4.

[0037] The main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 also include positioning and locking pins 6, which are used for positioning and locking the main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 after they have moved into place on the gantry linear guide rail.

[0038] Preferably, the positioning locking pin 6 is a retractable positioning pin.

[0039] A trapezoidal positioning block is installed at the bottom center of the gantry 1 to cooperate with the lifting logistics vehicle. A trapezoidal groove of matching size is opened in the center of the lifting plate of the logistics vehicle for precise positioning and to ensure the stability of logistics transfer.

[0040] By placing two or more support devices in parallel alignment, the spacing and position of the main arc-shaped support assembly 2 and the secondary arc-shaped support assembly 3 are adjusted to be consistent, supporting both ends or the middle section of the engine.

[0041] The support device has an adjustable arc shape, adaptable to the support and transport of various cylindrical or near-cylindrical engines. The support device is suitable for engine housings with a diameter of 1500mm-2000mm.

[0042] Example:

[0043] The arc-shaped support frame 4 is made of steel, with a felt pad on its arc surface. The auxiliary support 5 is also made of steel, with a felt pad on its arc surface. The telescopic positioning pin 6 is made of metal and works with the rails on the slide rail to position the arc-shaped support frame 4. The assembly can support engine housings with diameters from Ф1500mm to Ф2000mm. The arc surface of the assembly is adapted to support housings with diameters up to Ф2000mm. Figure 4 As shown.

[0044] When supporting the Ф1500mm shell, adjust the distance between the arc seats on both sides of the arc-shaped support frame 4, and pass through the pre-reserved positioning slot at the upper end of the arc (see...). Figure 2 Install auxiliary support 5 (see) Figure 3 This design ensures proper support for a small-diameter (Ф1500mm) shell, preventing instability caused by rolling motion in the gaps on both sides of the shell. Figure 5 As shown.

Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description.
