DETAILED DESCRIPTION

[0021] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0022] like Figure 1(a) to Figure 1(c) As shown, a quick-release top cover type heat treatment material frame of the present invention comprises a main frame 1, a quick-release top cover 2 and a side door 3, and the whole frame is made of stainless steel material.

[0023] like Figure 2(a) to Figure 2(g) As shown, the main frame 1 is the main structural frame, which is welded with stainless steel material throughout, and specifically includes a short frame bottom profile 4, a long frame bottom profile 5, an auxiliary long profile 6, an auxiliary short profile 7, a frame bottom reinforcing rib plate 8, a main support column 9, an auxiliary support column 10, side oblique reinforcing ribs 11, a transverse reinforcing rib 12, a step 13, a long guide column 14, a short guide column 15, a frame top short profile 16, and a frame top long profile 17.

[0024] The short profile 4 and the long profile 5 of the frame bottom are both rectangular stainless steel tubes. The end faces are cut into bevels and then welded to ensure an angle of 90°. A smaller auxiliary long profile 6 and auxiliary short profile 7 are welded vertically and horizontally on the inner side of the short profile 4 and the long profile 5 of the frame bottom to form a profile grid. Finally, the profile grid is filled with the frame bottom reinforcing rib plate 8. The process is still welding. The four main support columns 9 are vertically welded on the short profile 4 and the long profile 5 of the frame bottom, and circular holes are reserved at the top. The end faces of the short profile 16 and the long profile 17 of the frame top are welded on the side of the support column 9 to form a right angle. At the top of the four main support columns 9, one is inserted into the long guide column 14, and the other three are inserted into the short guide columns 15, and they are welded and fixed. The long guide column 14 is about 50-100mm higher than the short guide column 15. The long guide column 14 and the short guide column 15 have shoulders and sit on the edge of the profile of the main support column 9, and the rest is inserted into the profile, and a through hole is opened to connect with the circular hole of the main support column 9. The auxiliary support column 10 is welded between the long profile 5 at the bottom of the frame and the long profile 17 at the top of the frame. The stainless steel step 13 is welded in the middle and lower part of the auxiliary support column 10 for manual climbing; the side oblique reinforcement ribs 11 are obliquely welded between the auxiliary support columns 10 on each side to form a "small" shape, and the transverse reinforcement ribs 12 are welded between the main support column 9 and the adjacent side oblique reinforcement ribs 11 for manual climbing. Two hinges b31 are welded on the four main support columns 9 respectively for connecting the side door 3.

[0025] like Figure 3(a) to Figure 3(e) The quick loading and unloading top cover 2 mainly includes a long beam 19, a short beam 18, an auxiliary short beam 21, a lifting lug 24, a connecting foot 20, a fitting foot square steel 22, a fitting foot channel steel 23, an auxiliary structure 25 and other parts. The long beam 19 and the short beam 18 are welded into a main rectangular frame. The welding form is that the two end surfaces of the short beam 18 are welded on the side of the long beam 19. The auxiliary short beams 21 have slightly larger profiles and are also welded on the inner side of the long beam 19. The lifting lug 24 is formed by bending a stainless steel rod and is directly welded on the upper surface of the long beam 19. Auxiliary structures 25 are added on both sides of the lifting lug 24. The lower surface of the butt joint of the auxiliary short beam 21 and the short beam 18 is welded with connecting feet 20, and the function of the four connecting feet 20 is to fit on the outside of the long guide column 14, the short guide column 15 and the matching main support column 9 of the main frame 1, and complete the connection with the long guide column 14 and the short guide column 15 through the insurance b34 and the latch 35; the fitting foot square steel 22 is welded on the lower surface of the welding area of ​​the auxiliary short beam 21 and the long beam 19, and the fitting foot square steel channel steel 23 is welded on the lower surface of the fitting foot square steel 22, and the function of the fitting foot square steel 22 is to fit on the upper surface and two side surfaces of the frame top long profile 17 of the main frame 1 to prevent the frame top long profile 17 from being deformed at high temperature.

[0026] As shown in Figures 4(a) and 4(b), the side door 3 includes a short side door profile 26, a long side door profile 27, a long internal side door profile 28 and a short internal side door profile 29; the end faces of two short side door profiles 26 and two long side door profiles 27 are cut into bevels and butt-welded, and an internal long side door profile 28 and two internal short side door profiles 29 are welded into an "X" shape and then welded at the four corners of the short side door profile 26 and the long side door profile 27, and two hinges a30 are respectively welded on the long side door profile 27 for connecting to the main frame 1.

[0027] like Figure 5 As shown, the side door 3 is connected to the main frame 1 through a pin 32 and a safety a33, specifically, the hinge a30 of the side door 3 and the hinge b31 of the main frame 1 are manually engaged. Figure 6(a) to Figure 6(c) , use hanging to lift the quick-loading and unloading top cover 2, and first fit one of the connecting feet 20 onto the long guide column 14, and the other three connecting feet 20 are respectively fit onto the three short guide columns 15, and the quick-loading and unloading top cover 2 falls until the bottom end surfaces of the four connecting feet 20 all "sit" on the long frame top profile 17 of the main frame 1. At this time, the circular holes on the main support columns 9, the circular holes of the guide columns and the circular holes of the connecting feet 20 coincide with the axes, and the latch 35 and the safety b34 are connected. At this time, the fitting foot channel steel 23 just "rides" on the long frame top profile 17 of the main frame 1, completing the connection between the quick-loading and unloading top cover 2 and the main frame 1.
