Description

Technical Field

[0001] This invention relates to the field of telescopic housing technology, and more particularly to a trackless telescopic dust removal room with side walls. Background Technology

[0002] A retractable house is a special environmentally friendly housing device that unfolds to form a closed or semi-closed room when in use and retracts to close when not in use. Ordinary roof-mounted retractable houses generally use dual motors, but due to slippage of the friction wheels on both sides, limit switches are often required for correction after operation. Moreover, for large-span linear guides, it is impossible to ensure that the two linear guides are parallel during installation. Therefore, when the retractable house is running, the slider may not be able to run smoothly on the two guide rails, and the stroke of the sliders at both ends may be inconsistent, which may cause the slider to tilt and get stuck on the linear guide rails, resulting in the retractable house being unable to open or close.

[0003] Currently, there is a lack of equipment that uses a linkage drive assembly to ensure unobstructed sliding, enabling the use of telescopic dust collection chambers, and facilitating the unfolding and cleaning of the side walls during telescopic movement.

[0004] Therefore, to address the above problems, a trackless telescopic dust collection chamber with side walls is proposed to solve these issues. Summary of the Invention

The device employs large and small connecting rods to limit the longitudinal displacement of the bottom beam, ensuring linear movement during chamber retraction and extension. This device is suitable for large welding dust removal chambers, and after the chamber is retracted, there is no obstruction or interference at the workstation.

[0016] This device uses a bottom beam connected to a cross block to achieve synchronous extension and retraction of the sidewall and cleaning roller following the bottom beam. At the same time, using connecting rods, outer shafts, and inner shafts, the cleaning roller moves along the sidewall surface to clean the sidewall. In the final stage of cleaning at the top, the conical bottom guide rod is inserted into the guide hole to maintain the relative position of the cleaning roller and the sidewall. After the bottom beam extends to its full position, the cleaning roller detaches from the sidewall, at which point the sidewall swings open to form overlapping planes. After the work is completed, the sidewall swings in the opposite direction, the bottom beam retracts, and the cleaning roller moves downward to contact the sidewall again, cleaning the sidewall from top to bottom and removing dust that floats on the sidewall during the work process.

[0039] The two ends of the sidewall 38 are respectively provided with mating grooves 39. By providing mating grooves 39, the sidewalls 38 come into contact with each other after being unfolded, forming an overlapping sealing plane.

[0040] The lower ends of the space frame 11 are respectively connected to the diagonal bracing frame 13.

[0041] The grid frame 11 is connected to the geared motor 21, and the geared motor 21 is connected to the drive shaft 22 through a transmission chain mechanism. The transmission chain mechanism includes a driving sprocket, a transmission chain, and a driven sprocket. The output of the geared motor 21 is connected to the driving sprocket, and the drive shaft 22 is connected to the driven sprocket. The driven chain surrounds the driving sprocket and the driven sprocket.

[0042] The workflow of this embodiment is as follows:

[0043] In use, the geared motor 21 is controlled to rotate, which in turn rotates the drive shaft 22. The drive shaft 22 drives the gearbox 23 to work, which in turn drives the drive wheel 212 to rotate. The drive wheel 212 drives the chain 211 to move, which in turn drives the driven wheel 210 to rotate. The driven wheel 210 drives the rotating shaft 24 to rotate, which in turn drives the main load-bearing cantilever 25 to swing. The main load-bearing cantilever 25 drives the rear slide rail mounting square tube 26 and the front slide rail mounting square tube 28 to swing. The rear slide rail mounting square tube 26 and the front slide rail mounting square tube 28 drive the front and rear slide rail mounting square tube connecting rod 27 to swing.

The second slider 219 drives the second slide rail 218 (except for the innermost second slide rail 218) to move. The second slide rail 218 (except for the innermost second slide rail 218) drives the middle bottom beam 29 (except for the outermost and innermost bottom beams 29) to move. Except for the innermost bottom beam 29, the other bottom beams 29 drive the round shaft 217 to move. Except for the two inner bottom beams 29, the other bottom beams 29 drive the first slide rail 215 and the first slider 216 to move. The round shaft 217 drives the large connecting rod 213 and the small connecting rod 214 to swing. The large connecting rod 213 drives the first slider 216 to move along the first slide rail 215, realizing the extension and retraction of the bottom beam 29. Except for the innermost bottom beam 29, the other bottom beams 29 drive the cross block 35 to move along the cross groove 14. The cross block 35 drives the L plate 34, the driven bevel gear 36, the mounting shaft 37, and the side wall 38 to move. The L plate 34 drives the square hole shaft 310 to move along the square rod shaft 32. The square hole shaft 310 drives the driving bevel gear 33 to move.

Each symmetrical vertical groove 17 is provided with a guide groove 19. Vertical guide rods 18 are connected to each symmetrical vertical groove 17. Cleaning components 4 are respectively provided within each symmetrical vertical groove 17. Each cleaning component 4 includes symmetrical blocks 46. Corresponding blocks 46 are provided within each symmetrical vertical groove 17. The symmetrical vertical guide rods 18 pass through the corresponding blocks 46. The symmetrical blocks 46 are respectively connected to inner shafts 45. The symmetrical inner shafts 45 are respectively provided with… Within the corresponding guide groove 19, symmetrical inner shafts 45 are connected to transverse grooves 43, and transverse guide rods 44 are connected to the transverse grooves 43. A set of moving blocks 411 is provided within each transverse groove 43. The transverse guide rods 44 pass through the corresponding moving blocks 411, and the symmetrical moving blocks 411 are respectively connected to symmetrical cleaning rollers 410 via bearings. The symmetrical inner shafts 45 are rotatably connected to one end of a connecting rod 42, and the other end of the connecting rod 42 is rotatably connected to an outer shaft 41. The symmetrical outer shafts 41 are respectively connected to the corresponding cross blocks 35. By using cleaning rollers 410, the cleaning rollers 410 can move along the sidewall 38, achieving surface cleaning of the sidewall 38.

[0045] Each cleaning roller 410 is connected to a guide block 48 by a bearing. Each guide block 48 is provided with a guide hole 49, and each guide hole 49 is matched with a conical bottom guide rod 47. Each conical bottom guide rod 47 is connected to the corresponding bottom beam 29. This device uses the cooperation of the guide hole 49 and the conical bottom guide rod 47 to achieve the position retention of the cleaning roller 410 after it is detached from the side wall 38, which facilitates the unfolding of the side wall 38, and the matching of the cleaning roller 410 with the side wall 38 after the side wall 38 is reset.

[0046] In the initial state, such as Figure 1 As shown, each of the sidewalls 38 is disposed between the symmetrical cleaning rollers 410.

[0047] The workflow of this embodiment is as follows: the outermost cross block 35 drives the outermost shaft 41 to move, the bottom beam 29 drives the conical bottom guide rod 47 to move, the outermost shaft 41 drives the connecting rod 42 to swing, the connecting rod 42 drives the inner shaft 45 to move along the guide groove 19, the inner shaft 45 drives the block 46 to move along the vertical guide rod 18 in the vertical groove 17, the inner shaft 45 drives the horizontal groove 43, the horizontal guide rod 44, the moving block 411, the cleaning roller 410 and the guide block 48 to move upward, the side wall 38 drives the cleaning roller 410 to move along the surface of the side wall 38 to achieve cleaning, the cleaning roller 410 drives the moving block 411 to move along the horizontal guide rod 44 in the horizontal groove 43, the cleaning roller 410 drives the guide block 48 to move, when the guide block 48 is inserted upward into the conical bottom guide rod 47, the conical bottom guide rod 47 drives the guide block 48 to move, the guide block 48 drives the cleaning roller 410 and the moving block 411 to move, so that after the cleaning roller 410 is separated from the side wall 38, it maintains a position matching with the side wall 38.

[0048] Example 3: This example is a further elaboration based on Example 1 or Example 2. Each second slider 219 is connected to one end of the slide rail telescopic protective cover 220. The slide rail telescopic protective cover 220 is matched with the corresponding second slide rail 218, and the other end of the slide rail telescopic protective cover 220 is connected to the end of the second slide rail 218 to prevent dust from causing the second slider 219 to run sluggishly.

[0049] This device uses a bottom beam 29 connected to a cross block 35 to achieve synchronous extension and retraction of the side wall 38 and the cleaning roller 410 following the bottom beam 29. At the same time, the cleaning roller 410 moves along the surface of the side wall 38 by using a connecting rod 42, an outer shaft 41, and an inner shaft 45, thus cleaning the surface of the side wall 38. When the upper cleaning enters the final stage, the conical bottom guide rod 47 is inserted into the guide hole 49 to maintain the relative position of the cleaning roller 410 and the side wall 38. After the bottom beam 29 extends to its position, the cleaning roller 410 disengages from the side wall 38. At this time, the side wall 38 swings and unfolds, forming overlapping planes. After the work is completed, the side wall 38 swings in the opposite direction, the bottom beam 29 retracts, and the cleaning roller 410 moves downward to contact the side wall 38 again. From top to bottom, the side wall 38 is cleaned, removing the dust that floats on the side wall 38 during the work process.
