[0032] The frame 1 is provided with a reference positioning unit 3 and a push limit unit 4 for positioning the side wall at both ends and along its width direction.

[0033] The adjacent side walls arranged side by side on the beam support 2 are clamped and positioned by the weld clamping unit 5 to prevent the side walls from shifting. The side walls at both ends of the frame 1 are respectively abutted against the corresponding reference positioning unit 3 and the push limit unit 4.

[0034] The beam support 2 is provided with a plurality of pressing block limiting units 6 for limiting the pressing blocks of the top beam and the bottom beam supported on the beam support 2 .

[0035] like Figure 1 , 2 As shown, in order to realize the positioning and clamping of the side walls of the dust removal equipment of different specifications, multiple groups of beam supports 2 with different heights for matching the clamping of side walls of different specifications are provided on both sides of the frame 1, and the multiple groups of beam supports 2 are arranged in sequence from high to low according to the outermost side of the frame 1. At the same time, each group of beam supports 2 is provided with a corresponding pressure block limit unit 6.

[0036] Furthermore, the utility model provides three groups of beam supports 2 with different heights on both sides of the frame 1. The frame 1 arranges the three groups of beam supports in sequence in height from the outermost side to the inner side. The highest beam support 2 is provided with a height column to support large-sized side walls and partial top beams and bottom beams matching the large-sized side walls. The remaining groups of beam supports 2 are used to support side walls of corresponding specifications of equal size. When positioning, they only need to be supported side by side on the beam support 2. At the same time, two groups of reference positioning units 3 with different heights are provided on the frame 1. The higher group of reference positioning units 3 is used to match the large-sized side walls, and the lower group of reference positioning units 3 is used for the remaining two types of side walls.

[0037] like Figure 2 As shown, in order to further improve the rationality of the structure and realize the reference positioning of the end side wall, the reference positioning unit 3 includes a reference positioning seat 31 and a reference positioning block 32. The reference positioning seat 31 is arranged at one end of the frame 1, and the reference positioning block 32 is installed on the inner side wall of the reference positioning seat 31, so as to abut against the side wall at one end of the frame 1 to realize the reference positioning of the side wall.

[0038] like Figure 3 As shown, in order to realize positioning of the side wall at the other end of the frame and to have a certain margin of adjustment, the pushing limit unit 4 includes a pushing limit seat 41, a slide bar seat 42, a pushing handle seat 43, a pushing handle 44, a push rod 45, a pushing limit plate 46, a slide bar 47 and a connecting plate 48. The pushing limit seat 41 is fixed on the frame 1, and the slide bar seat 42 and the pushing handle seat 43 are both arranged on the pushing limit seat 41. The pushing handle 44 is hinged to the pushing handle seat 43 through a hinge shaft. At the same time, one end of the pushing handle 44 and the push rod 45 is also rotatably connected to a connecting piece through a pin shaft. In order to realize positioning of the side wall at the other end of the frame and to have a certain margin of adjustment, the pushing limit unit 4 includes a pushing limit seat 41, a sliding bar seat 42, a pushing handle seat 43, a pushing handle 44, and a pushing limit plate 46. The sliding bar seat 42 and the pushing handle seat 43 are both arranged on the pushing limit seat 41. The pushing handle 44 is hinged to the pushing handle seat 43 through a hinge shaft. At the same time, one end of the pushing handle 44 and the pushing rod 45 is also rotatably connected to a connecting piece through a pin shaft. The push rod 45 plays a guiding role. A guide sleeve is provided on the push handle seat 43. The push rod 45 passes through the guide sleeve, and the other end of the push rod 45 is detachably connected to the connecting plate 48. The slide bar 47 connected to the connecting plate 48 is slidably matched with the slide bar seat 42 in an axial hole. The push limit plate 46 is provided at the end of the slide bar 47. The push handle 44 is rotated to make the push limit plate 46 pushed out under the action of the slide bar 47, and used to abut against the side wall at the other end of the frame 1 to limit the side wall. Conversely, the push handle 44 is rotated again, and the push limit plate 46 retracts to the initial position with the slide bar 47, thereby releasing the abutment against the corresponding side wall.

[0039] like Figure 4 As shown, in order to clamp and position adjacent side walls, ensure that there is no gap when welding adjacent side walls, and further improve welding accuracy, the weld clamping unit 5 includes a clamping reference block 51, a handle seat 52, a clamping handle 53, a positioning connecting seat 54 and a clamping positioning block 55. The handle seat 52 is installed on the clamping reference block 51, and the positioning connecting seat 54 is rotatably connected to the handle seat 52. The clamping handle 53 is rotatably connected to the handle seat 52 and the positioning connecting seat 54 through a connecting piece. The clamping positioning block 55 is adjustably connected to the positioning connecting seat 54. The clamping reference block 51 is abutted against one of the adjacent side walls. The clamping handle 53 is rotated to make the clamping positioning block 55 abut against the other side wall of the adjacent side walls, thereby realizing the clamping and positioning of the adjacent side walls. The clamping handle 53 is rotated again to release the abutment of the clamping positioning block 55 against the side wall.

[0040] like Figure 1 , 2 As shown, in order to meet welding requirements and facilitate subsequent lifting, the beam supports 2 on both sides of the frame 1 are provided with a plurality of separately arranged pads 21 for supporting the top beam and the bottom beam.

[0041] Furthermore, in order to make the structure more reasonable, the pad 21 is an L-shaped pad, and the L-shaped pad can position the outer side surfaces of the top beam and the bottom beam, further improving the positioning accuracy.

[0042] like Figure 5As shown, in order to ensure that the top beam and the bottom beam are relatively fixed with the corresponding beam support and to ensure the quality of subsequent welding, the pressure block limiting unit 6 includes a mounting base 61, a pressure block seat 62, a pressure block handle 63 and a pressure block 64. The mounting base 61 is arranged on the beam support 2, and the pressure block seat 62 and the pressure block handle 63 are both rotatably connected to the mounting plate on the mounting base 61. The pressure block 64 is detachably connected to the pressure block seat 62. By rotating the pressure block handle 63, the pressure block 64 is driven to rotate and be crimped into the groove of the top beam or the bottom beam on the beam support 2 through the pressure block seat 62. By rotating the pressure block handle 63 again, the pressure block 64 can be separated from the groove of the top beam or the bottom beam, thereby releasing the pressure on the top beam or the bottom beam.

[0043] like Figure 1 , 2 As shown, in order to facilitate the overall lifting and transportation, lifting rings 11 are respectively provided at both ends of the frame 1 for convenient lifting and transportation.

[0044] When the utility model is used, it is used in conjunction with a welding robot. First, according to the specifications of the side walls to be welded and assembled, a beam support 2 of a suitable height is selected, that is, multiple side walls 7 are placed side by side, and their two ends are supported on the beam support 2 of corresponding heights. At the same time, the top beam 8 and the bottom beam 9 are also supported on the beam support 2 respectively to complete the initial positioning.

[0045] At the same time, the side wall 7 at one end of the frame 1 abuts against the reference positioning block 32 of the reference positioning unit 3, and the side wall 7 at the other end of the frame 1 abuts against the push limit unit 4. Specifically, the push handle 44 is rotated to push the limit plate 46 out under the action of the slide rod 47, and is used to abut against the side wall at the other end of the frame 1 to achieve the limit of the side wall.

[0046] The adjacent side walls 7 are clamped and positioned by the weld clamping unit 5. Specifically, the clamping handle 53 is rotated to make the clamping and positioning block 55 abut against another side wall of the adjacent side walls, thereby achieving the clamping and positioning of the adjacent side walls.

[0047] The top beam 8 and the bottom beam 9 are also respectively pressed and limited by the pressing block limiting unit 6 on the beam support 2. Specifically, the pressing block handle 63 is rotated, and the pressing block 64 is driven to rotate through the pressing block seat 62 and press-fit into the groove of the top beam or the bottom beam on the beam support 2. At this time, the side wall 7 and the top beam 8 and the top beam 9 complete the final precise positioning.

[0048] Finally, the welding robots are used to complete the butt welding of adjacent side walls, as well as the welding connections between the side walls and the top and bottom beams.

[0049] The utility model can realize multi-point positioning of the side wall, the top beam and the bottom beam, replacing the technical solution of using support blocks placed on the ground for reference positioning in the prior art, greatly improving the positioning accuracy and positioning efficiency, and thus also improving the subsequent welding quality and welding efficiency. At the same time, the utility model also has the advantages of being suitable for clamping and positioning of side walls of various specifications, and having a simple structure and being easy to use.

[0050] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
