Description

Technical Field

[0001] This utility model relates to a horizontal fitting device for internal components of an aerospace gasification furnace, belonging to the technical field of rigid mechanical devices for transmitting lifting force to objects during traction (B66C1 / 22). Background Technology

[0002] As a landmark achievement in the localization of core equipment in my country's coal chemical industry, the aerospace gasifier has been widely used in coal chemical, coal gasification, coal oil, and coal chemical industries. In the manufacturing process of the fully quenched process aerospace pulverized coal gasifier, the assembly process of the gasification internals and the gasifier shell is the core challenge restricting overall manufacturing efficiency and final product quality. Currently, the industry mainly divides the assembly process of gasification internals and the shell into two categories: vertical assembly and horizontal assembly. The vertical assembly process, which requires large pits, high-level heavy-duty cranes for hoisting operations, and extensive scaffolding both inside and outside the shell for installation, is too labor-intensive and resource-intensive, and has been gradually replaced by the horizontal assembly process.

[0003] However, due to the lack of targeted anti-tilting and stable positioning measures, the gasification internals are prone to excessive tilting and axial displacement during the traditional horizontal fitting process. In addition, uneven stress and difficulty in controlling the hoisting posture can also easily cause plastic deformation of the gasification internals, which ultimately seriously affects the stability of the gasifier's long-term operation. Utility Model Content

The two ends extend from the two ports of the vaporization inner component; one end of the central tube is fitted with an annular end plate, and the other end of the central tube is fixed with at least one lifting lug; one side of the end plate is fixed to one end face of the vaporization inner component, and the other side of the end plate is fixed with multiple right-angled triangular fixing plates, the two right-angled sides of the fixing plates being fixed to the other side of the end plate and the surface of the central tube respectively; the lifting lug is connected to a pull rope; at least four support tubes are evenly fixed circumferentially on the outer wall of the central tube located at the center and both ports of the vaporization inner component, one end of each support tube is fixed to the outer wall of the central tube, and the other end of each support tube is fixed with an arc-shaped support plate, the arc-shaped support plate being fixed to the inner wall of the vaporization inner component by a pad.

[0006] Furthermore, the track includes two flat steel bars, which are symmetrically distributed and fixed parallel to each other on the inner wall of the bottom of the gasifier shell with the axis of the gasifier shell as the center line. The top surfaces of the two flat steel bars are both right angles, and the two flat steel bars are fixed together by multiple stiffening plates.

[0007] Furthermore, the trolley includes an arc-shaped support plate, at least four V-shaped track wheels, and connecting plates. The V-shaped track wheels are symmetrically arranged on the top surfaces of the two flat steel bars. Vertical plates are fixed on the bearings on both sides of the four V-shaped track wheels.

[0008] Furthermore, a counterweight is provided at one end of the central tube that is fitted with an annular end plate.

[0009] Furthermore, two lifting lugs symmetrically distributed along the axis of the central tube are fixed at the other end of the central tube.

[0010] The beneficial effects of this invention are as follows: A trolley pulls the gasification inner component along a track to complete the horizontal fitting operation. Angle plates and lead screws are provided to limit excessive tilting of the gasification inner component during the fitting process. Simultaneously, a central tube is installed through the gasification inner component, and a stable connection between the gasification inner component and the central tube is achieved through end plates, fixing plates, and support plates.

[0022] This embodiment describes a horizontal fitting device for internal components of an aerospace gasifier, as shown in the example. Figure 1 As shown, it includes a gasifier shell 1 placed horizontally on the ground, and gasification components 2 and a central tube 3 placed inside the gasifier shell 1; a pulley 4 is fixed to the top inner wall of the gasifier shell 1, and a track 5 is provided along its axial direction on the bottom inner wall of the gasifier shell 1. Figure 2 , 3 As shown, the track 5 includes two flat steel bars 6, which are symmetrically distributed around the axis of the gasifier shell 1 and fixed parallel to the bottom inner wall of the gasifier shell 1. The top surfaces of the two flat steel bars 6 are both right angles, and the two flat steel bars 6 are fixed together by multiple stiffening plates 7. A trolley 8 is provided on the track 5 and slides with the track 5. The trolley 8 includes an arc-shaped bearing plate 9, at least four V-shaped track wheels 10, and connecting plates 11. The V-shaped track wheels 10 are symmetrically arranged on the top surfaces of the two flat steel bars 6. Vertical plates 12 are fixed on the bearings on both sides of the four V-shaped track wheels 10. The top surfaces of the vertical plates 12 on both sides of one V-shaped track wheel 10 are fixed to the bottom surface of a connecting plate 11. The top surfaces of all connecting plates 11 are fixed to the bottom surface 9 of the bearing plate. The gasification internals 2 are placed on the top surface of the arc-shaped bearing plate 9 of the trolley 8.

[0023] like Figure 4 , 5 As shown, connecting plates 13 are fixed to the top surfaces of both ends of the gasification internal component 2. Vertical L-shaped corner plates 14 are fixed to the top surface of the connecting plates 13. Screws 15 are fixed to the vertical surfaces of the corner plates 14. The screws 15 are driven by motors 16 fixed to the bottom of the corner plates 14.

[0024] The central tube 3 extends axially through the interior of the vaporization inner component 2, with both ends of the central tube 3 extending out from the two ends of the vaporization inner component 2; for example... Figure 1 , 6 As shown in Figure 7, one end of the central tube 3 is fitted with an annular end plate 17, and the other end of the central tube 3 is fixed with two lifting lugs 18 symmetrically distributed along the axis of the central tube 3. One side of the end plate 17 is fixed to one end face of the vaporization inner component 2, and the other side of the end plate 17 is fixed with multiple right-angled triangular fixing plates 19. The surfaces of the fixing plates 19 containing the two right-angled sides are respectively fixed to the other side of the end plate 17 and the surface of the central tube 3; as shown in Figure 7. Figure 1 As shown, the lug 18 is connected to the pull rope 20.

[0025] like Figure 1 As shown in Figure 8, four support pipes 21 are uniformly fixed circumferentially on the outer wall of the central pipe 3 located at the center and two ends of the gasification inner component 2.

[0026] like Figure 1 As shown, the central tube 3, with its annular end plate 17, is also equipped with a counterweight 24 at one end to facilitate center of gravity adjustment during the fitting process. During the fitting operation of the gasification inner components, a crane is used to hoist the gasification inner component 2 onto the trolley 8, and the pull rope 20 is connected to the electric winch 25 outside the gasifier shell 1. This pulls the central tube 3 and moves the gasification inner component 2. After the gasification inner component 2 reaches the preset position, the pull rope is passed through the pulley 4, and the electric winch 25 is used to pull the pull rope 20 to lift the gasification inner component 2. The crane then lifts the end of the gasification inner component 2 with the counterweight, and the trolley is pulled out. Finally, the lateral position of both ends of the gasification inner component 2 is adjusted using the installed lead screw 15 to achieve precise fitting.
