[0028] Figure 2 This is an exploded schematic diagram of the lifting device for a furnace gas pipeline according to the present invention. Detailed Implementation

[0029] The following description is intended to provide a detailed account of the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0030] See Figure 1-2 The present invention provides a technical solution: a lifting device for a furnace gas pipeline, comprising:

[0031] The base 6 and pipe support beam 1 are horizontally set and arranged at intervals from bottom to top along the vertical direction;

[0032] An upper adjusting nut 31 is vertically set and fixedly connected to the center of the lower end of the pipe support beam 1. An adjusting screw 2 is screwed to the inner side of the upper adjusting nut 31. A lower adjusting nut 32 located below the upper adjusting nut 31 is screwed to the outer side of the adjusting screw 2. The lower adjusting nut 32 and the base 6 are fixedly connected. The threads on the inner sides of the upper adjusting nut 31 and the lower adjusting nut 32 are in the same direction.

[0033] The lifting assembly includes an upper lifting member connected to the upper adjusting nut 31 and a lower lifting member connected to the lower adjusting nut 32. The upper lifting member and the lower lifting member are movably connected in the vertical direction and constrained to move in the horizontal direction.

[0034] This lifting device can rotate the adjusting screw 2, which moves vertically through the lower adjusting nut 32. At the same time, the adjusting screw 2 drives the upper adjusting nut 31 to move vertically in cooperation with the lifting assembly, thereby driving the pipe support beam 1 or the base 6 to move up and down. This achieves efficient adjustment of the elevation of the pipe support beam 1. Furthermore, in conjunction with the lifting assembly to restrict the horizontal position, it ensures that the pipe fittings on the pipe support beam 1 can remain in a horizontal position during the adjustment process.

[0035] In this embodiment, the lifting device is suitable for adjusting the support at different heights in a hot environment with temperature rise to a horizontal state, and the pipe can be placed above the pipe support beam 1 along the length direction of the pipe support beam 1.

[0036] Furthermore, the upper lifting component includes a stiffening rib plate 7, which is supported and connected between the pipe support beam 1 and the upper adjusting nut 31. The stiffening rib plate 7 has a guide groove 10 arranged in the vertical direction. The lower lifting component includes a guide column 9, which is slidably connected to the inner side of the guide groove 10. The guide groove 10 is configured to constrain the guide column 9 to move in the horizontal direction. The guide column 9 can move in the vertical direction within the guide groove 10, thereby realizing the vertical movement of the upper adjusting nut 31 and the lower adjusting nut 32. The guide groove 10, in conjunction with the guide column 9, can restrict the pipe support beam 1 to be horizontal. Furthermore, the guide groove 10 can also provide a vertical limit for the guide column 9 to prevent the adjusting screw 2 from disengaging from the first adjusting nut and the second adjusting nut, which would cause the lifting structure to fail.

[0037] The lower lifting component also includes a vertical stiffener plate 5. The lower adjusting nut 32 and the base 6 are fixedly connected by the vertical stiffener plate 5. The vertical stiffener plate 5 is located on one side of the stiffening rib plate 7. The first end of the guide post 9 is fixedly connected to the vertical stiffener plate 5. The second end of the guide post 9 passes through the guide groove 10 to the other side of the stiffening rib plate 7 away from the vertical stiffener plate 5. The second end of the guide post 9 extends radially outward to form a limiting part. The limiting part is configured to constrain the movement of the guide post 9 toward the first end to prevent the guide post 9 and the guide groove 10 from slipping off, ensuring that both can move stably in the vertical direction. In this embodiment, the guide post 9 and the limiting part are M24 bolts, wherein the guide post 9 corresponds to the stud of the M24 bolt, and the limiting part corresponds to the head of the M24 bolt.

[0038] Furthermore, the stiffening rib 7 includes:

[0039] The pipe support beam 1 has an upper plate and a lower plate. The upper plate is fixedly connected to the radially outer side of the upper adjusting nut 31 and vertically connected to the lower end face of the pipe support beam 1. The lower edge of the upper plate extends downward from the side away from the upper adjusting nut 31 to form the lower plate. That is, the lower plate and the upper adjusting nut 31 are arranged at intervals in the horizontal direction. The guide groove 10 is formed in the lower plate. In this embodiment, the pipe support beam 1 is an I-beam, and the lower part of the pipe support beam 1 is a lower flange plate. The lower end face of the pipe support beam 1 is the lower end face of the lower flange plate.

[0040] Furthermore, a protective plate 8 is provided on the side of the stiffening rib 7 away from the upper adjusting nut 31. The protective plate 8 supports and is perpendicular to the lower end face of the stiffening rib 7 and the pipe support beam 1. By adding the protective plate 8, on the one hand, the protective plate 8 can further improve the connection strength between the stiffening rib 7 and the lower flange of the pipe support beam 1. On the other hand, the protective plate 8 can abut against the upper edge of the vertical stiffener 5 during the process of lowering the device height, and has a certain limiting effect. Furthermore, the size of the protective plate 8 gradually decreases from top to bottom and is in the shape of an isosceles trapezoid.

[0041] The vertical stiffening plate 5 is an L-shaped vertical stiffening plate 5. Specifically, the vertical stiffening plate 5 includes:

[0042] The horizontal plate and the vertical plate are connected to the radially outer side of the lower adjusting nut 32. The horizontal plate extends outward in the horizontal direction, and the end of the horizontal plate is connected to the vertical plate. The vertical plate extends downward and is connected to the upper end of the base 6.

[0043] Furthermore, the adjusting screw 2 is provided with a lifting component on each of its opposite sides in the horizontal direction.

[0044] Furthermore, the distance between the vertical plate and the axis of the adjusting screw 2 gradually increases from top to bottom, that is, the lower end of the vertical plate tilts outward, and the width of the vertical plate gradually increases from top to bottom, so as to further improve the stability of the connection between the vertical rib plate 5, the base 6 and the lower adjusting nut 32.

[0045] Furthermore, the base 6 is a cross-shaped base 6, which includes a bracket 1 and a bracket 2 arranged vertically intersecting on a horizontal plane. The bracket 1 and the pipe support beam 1 are parallel to each other. The lower end of the vertical rib plate 5, i.e. the lower end of the vertical plate, is connected to the bracket 1. A vertical rib plate 5 is connected to each side of the intersection of the bracket 1 and the bracket 2.

[0046] Specifically, both bracket one and bracket two are I-beams. There are two brackets one. Bracket one and bracket two are spliced ​​together to form the base 6. Bracket one is respectively set on both sides of bracket two. The waist plate of bracket one extends outward toward the side of bracket two and is inserted into the area enclosed by the lower flange plate, upper flange plate and waist plate of bracket two.

[0047] In this embodiment,

[0048] The upper adjusting nut 31 is welded to the center position of the lower flange plate of the pipe support beam 1. The stiffening rib 7 is welded to both sides of the upper adjusting nut 31 at a 20mm offset from the longitudinal center line of the lower flange plate of the pipe support beam 1. The stiffening rib 7 and the lower flange plate of the pipe support beam 1 are corner welded.

[0049] The stiffening rib 7 is provided with a long guide groove 10, the width of which is sufficient to pass through the thread of an M24 bolt. The outer end of the stiffening rib 7 is attached with a protective plate 8 and corner welded to the lower flange of the pipe support beam 1.

[0050] The adjusting screw 2 is screwed into the upper adjusting nut 31, and the lower end of the adjusting screw 2 then passes through the lower adjusting nut 32 in sequence. The lower end of the adjusting screw 2 is welded with a disc handle 4.

[0051] The lower adjusting nut 32 has L-shaped vertical stiffening plates 5 welded on both sides of its radial direction. The upper end of the vertical stiffening plate 5 is welded to the same side of the guide post 9 made of M24 bolts. The guide post 9 can be inserted into the guide groove 10 and can slide up and down in the guide groove 10 without obstruction along the length direction of the adjusting screw 2.

[0052] The lower end of the vertical stiffener plate 5 is welded to the upper end face of the base 6.

[0053] In use, the rotating disc handle 4 drives the adjusting screw 2 to rotate, converting the rotational motion into the up-and-down motion of the adjusting screw 2, thereby causing the pipe support beam 1 and the base 6 to move synchronously up and down with the adjusting screw 2.

[0054] In summary, this lifting device can manually raise and lower the support of the furnace gas pipeline. Its main principle is to rotate the adjusting screw 2 to make the adjusting screw 2 move vertically, which drives the pipe support beam 1 or base 6 at the top of the adjusting screw 2 to move up and down. It is suitable for supports of different heights in hot environments with temperature rise.

[0055] The lifting device has an upper adjusting nut 31 and a lower adjusting nut 32 on its outer periphery of the adjusting screw 2. A vertical stiffening plate 5 is welded to the outside of the lower adjusting nut 32 for support. A guide column 9 made of M24 bolts is welded to one side of the upper part of the vertical stiffening plate 5, and the lower end is welded to the cross base 6.

[0056] The upper adjusting nut 31 inserted into the upper end of the adjusting screw 2 is welded to the lower end of the pipe support beam 1. A stiffening rib 7 with a guide groove 10 is welded to the outside of the upper adjusting nut 31, and a guide column 9 is embedded in the guide groove 10.

[0057] By rotating the disc handle 4 at the lower end of the adjusting screw 2, the adjusting screw 2 is moved vertically, which drives the pipe support beam 1 or base 6 at the top of the adjusting screw 2 to move up and down, thereby adjusting the overall horizontal height of the support.

[0058] By rotating the adjusting screw 2, the screw moves vertically, causing the pipe support beam 1 or base 6 above the adjusting screw 2 to move up and down, adjusting the horizontal height of the support. The guide groove 10 is fitted with the guide column 9, which can limit and control the pipe support beam 1 to be horizontal.

[0059] The lifting device has a simple structure and is easy to operate. By rotating the adjusting screw 2, the adjusting screw 2 is moved vertically, which drives the pipe support beam 1 or base 6 at the top of the adjusting screw 2 to move up and down, so that the gas pipe support is in a horizontal state, which can meet the needs of adjusting the horizontal height difference of the furnace pipe support in a hot temperature environment.

[0060] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.
