Description

Technical Field

[0001] The invention relates to the field of suspended ceiling keels, and in particular to a suspension rod-free square light steel keel processing device and a suspended ceiling structure thereof. Background Art

[0002] At present, the common method of ceiling decoration is to drill holes in the ceiling concrete and hang several array-distributed hangers, and then use fasteners to form a square tube network structure under the hangers. Finally, the gypsum board is fixed and hung to the bottom of the square tube network through fasteners such as steel nails. The preliminary work of this ceiling structure is extremely cumbersome. Not only does it take a lot of time and energy to drill expansion bolt holes on the ceiling, but the large number of hangers also makes it difficult to reduce the cost of the ceiling. At the same time, the U-shaped side rails that are indispensable in the process of forming the square tube network structure need to be cut to a fixed length manually during on-site construction. The function of the U-shaped side rails is to align and connect the outermost ends of the square tubes. The length of the U-shaped side rails is generally a factory-fixed specification, and the actual decoration will be cut on-site according to the required length. The general practice is to use tools such as needle-nosed pliers to cut directly during on-site production, which causes the cut end to be skewed and deformed. Finally, local shaping is required in the process of fixing the gypsum board to prevent the unevenness of the gypsum board after fixing caused by local deformation. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1As shown, a square light steel keel ceiling structure without a hanger rod comprises two U-shaped side rails 4 arranged in parallel and a plurality of square tubes 5 spaced and distributed between the two U-shaped side rails 4. The U-shaped side rails 4 are fixedly connected to the building wall 1 by a plurality of steel nails 3. All square tubes 5 are perpendicular to the U-shaped side rails 4. Both ends of each square tube 5 are slidably embedded in the corresponding U-shaped side rails 4. A wall layer decorative plate 2 is also arranged on the cavity wall of the building wall 1 below the U-shaped side rails 4. The present invention directly fixes the U-shaped side rails 4 on the building wall 1 by expansion bolts or steel nails 3 to construct a slide rail structure for erecting the square tubes 5. Finally, the gypsum board 71 for the ceiling is hung and fixed to the bottom of the square tube 5 network by screws. At the same time, a wall layer decorative plate 2 is also arranged on the building wall 1 to support the lower edge of the U-shaped side rails 4 upwards to prevent the U-shaped side rails 4 from deforming and falling. The present invention greatly simplifies the process of ceiling and reduces the decoration cost.

[0036] Reference Figures 2 to 15 A kind of square light steel keel processing equipment without a hanger, the processing equipment includes an optical axis bracket 6, a tail end support mechanism 7 fixedly arranged at one end of the optical axis bracket 6, a precision cutting device and a front end traction mechanism 8 movably arranged on the optical axis bracket 6, the tail end support mechanism 7, the precision cutting device and the front end traction mechanism 8 are distributed on the optical axis bracket 6 in sequence, the precision cutting device includes a side cutting mechanism 9 and a cross cutting mechanism 10 located above the side cutting mechanism 9, the side cutting mechanism 9 and the cross cutting mechanism 10 are both movably arranged on the optical axis bracket 6, the optical axis bracket 6 is provided with a scale 11 consistent with its length direction, and the side cutting mechanism 9 and the cross cutting mechanism 10 are both provided with a pointer bar 12 matching the scale value.

[0037] The processing device is used for on-site fixed-length cutting and manufacturing of U-shaped side rails 4 with neat cut edges at the decoration site. When in use, one end of the entire U-shaped side rail 4 is first extended into the optical axis bracket 6 from the rear end support mechanism 7, and then the U-shaped side rail 4 is passed through the precision cutting mechanism and finally enters the front end traction mechanism 8 to be clamped, and then the front end traction mechanism 8 is pulled to slide on the optical axis bracket 6 to the other end until it stops, thereby completely pulling the U-shaped side rail 4 into the inner side of the optical axis bracket 6, and the cross-cutting mechanism 10 and the side-cutting mechanism 9 with the scale 11 can be slid according to the indication of the scale 11 to the corresponding positions to prepare for fixed-length cutting, first the U-shaped side rail 4 is cut for the first time by the side-cutting mechanism 9 or the cross-cutting mechanism 10, and then the U-shaped side rail 4 is cut for the second time by the side-cutting mechanism 9 or the cross-cutting mechanism 10, thereby cutting the U-shaped side rail 4 with neat edges to a fixed length, and the cross-cutting mechanism 10 and the side-cutting mechanism 9 are used selectively during the entire cutting process, without any particular order.

[0038] In order to ensure that the side cutting mechanism 9 can synchronously complete the cutting of the two side walls of the U-shaped side rail 4, the following features are specifically set:

[0039] The side cutting mechanism 9 includes a first cross beam 13, a positioning support seat 14, a driving mechanism towards each other and two sheet cutters 15. A first linear bearing 16 is fixedly embedded at both ends of the first cross beam 13. The two first linear bearings 16 are movably sleeved on the optical axis bracket 6. The pointer bar 12 is fixedly arranged on the top of one end of the first cross beam 13. The positioning support seat 14 is mounted in the middle of the first cross beam 13. A positioning base 17 is fixedly connected to the middle of the bottom of the first cross beam 13. The bottom middle position of both side walls of the positioning base 17 is formed with a positioning column 18 extending upward. The bottom middle position of both side walls of the positioning support seat 14 is provided with a slot for the positioning column 18 to enter. The first cross beam 13 is provided with two slide seats 20 symmetrically distributed about the positioning support seat 14 for sliding movement. The cross section of the slide seat 20 is an inverted U shape and two guide pins 21 are fixedly connected between its two side walls and are spaced apart in the longitudinal direction. The first cross beam 13 is provided with two transverse slide grooves 22 for the guide pins 21 to slide. The top of each slide seat 20 is provided with a clamping handle 23 for fixing the sheet cutter 15. The opposite driving mechanism is arranged at the bottom of the first cross beam 13. The two moving output ends of the opposite driving mechanism are respectively fixedly connected to the two slide seats 20. The two side walls of the positioning support seat 14 are provided with side knife grooves 24 for the sheet cutter 15 to be embedded.

[0040] The U-shaped side rail 4 enters the optical axis bracket 6 in an inverted state and passes through the side cutting mechanism 9 in a posture of completely covering the positioning support seat 14. The inner wall of the U-shaped side rail 4 is completely in contact with the top wall and the two side walls of the positioning support seat 14, thereby ensuring the quality of the cutting process. The two slides 20 are driven synchronously to approach the positioning support seat 14 through the opposite driving mechanism, so that the two side walls of the U-shaped side rail 4 are cut by squeezing the sheet cutters 15 arranged on the two slides 20 (the U-shaped side rail 4 used for the suspended ceiling is made of aluminum, and the wall thickness is commonly within 1 mm, which can be easily cut). In this process, the two side knife grooves 24 on the positioning support seat 14 are used to ensure that the sheet blades can squeeze in and thus ensure that the two side walls of the U-shaped side rail 4 are cut and separated; the sheet blades are connected to the splint handle 23 by bolts, and can be easily replaced after a period of use; the guide pins 21 distributed at intervals on the slide 20 cooperate with the two transverse slide grooves 22 to ensure that the slide 20 will not tilt or shift during the translation process.

[0041] The positioning support seat 14 and the first crossbeam 13 are designed to be separated, and can be easily switched according to the model of the target U-shaped side rail 4 (the same batch of U-shaped side rails 4 only differ in width, generally 5mm wide, 10mm wide, 15mm wide, 20mm wide, etc.). It is only necessary to remove the positioning support block of the current width upwards, and install the positioning support seat 14 of the corresponding width, align the positioning groove 19 at the bottom of the side of the positioning support seat 14 with the positioning column 18 below and put it down. In this way, it is ensured that the inner wall of the U-shaped side rails 4 with different groove widths can be fully supported when cutting, thereby preventing deformation caused by lack of inner wall support.

[0042] In order to ensure that there is sufficient extrusion force to synchronously drive the sheet cutter 15 to cut the side of the U-shaped side rail 4, the following features are specifically set:

[0043] The opposite driving mechanism includes a hand-cranked threaded rod 25, a central gear 26 and two racks 27. The central gear 26 is fixedly connected to the bottom center of the first crossbeam 13. The two racks 27 are horizontally arranged at the bottom of the first crossbeam 13 and are symmetrical about the axis of the central gear 26. The ends of the two racks 27 that are close to each other are meshed with the central gear 26. The ends of the two racks 27 that are far away from each other are fixedly connected to the bottom of the corresponding slide 20 through an adapter plate 28. Each adapter plate 28 is fixedly connected At the bottom of the corresponding slide 20, one end of the rack 27 is fixedly connected to the adapter plate 28, and both sides of the bottom of the first beam 13 are formed with downwardly extending limit strips 29 for the back side of the rack 27 to fit, and a first connecting seat 30 for a hand-cranked threaded shaft to be connected is fixedly provided on the top of one end of the first beam 13, and a second connecting seat 31 is fixedly provided on the top of one of the slides 20 close to the first connecting seat 30, and the threaded end of the hand-cranked threaded rod 25 passes through the second connecting seat 31 and the two are threadedly matched.

[0044] The hand-cranked threaded rod 25 is rotated to drive the slide 20 threadedly matched therewith to translate, and the slide 20 translates while driving the rack 27 fixedly connected to the bottom thereof to move, and the rack 27 drives the rack 27 on the other side to translate synchronously through the central gear 26 meshing therewith, so that the slide 20 on the other side and the slide 20 on this side are synchronously close to the positioning support seat 14, and as the hand-cranked threaded rod 25 continues to rotate, until the two slices are squeezed from both sides to cut off the side wall of the U-shaped side rail 4 and enter the side knife groove 24. The limit bars 29 on both sides of the bottom of the first crossbeam 13 are used to contact and limit the outer side of the rack 27, thereby ensuring that the two racks 27 can remain meshed with the central gear 26.

[0045] In order to simplify the installation and rotational positioning of the hand-cranked threaded rod 25, the following features are specifically provided:

[0046] A through hole 32 is formed on one side of the first connecting seat 30 for the hand-cranked threaded rod 25 to pass through, and an inlay 33 is formed on one side of the first connecting seat 30 to vertically pass through the through hole 32. An annular inlay groove 34 with a diameter smaller than the main rod diameter is formed on the outer wall of the hand-cranked threaded rod 25 close to the hand-held end, and an F-type limit clamp 35 is provided in the inlay 33 for downwardly embedding into the annular inlay groove 34. A gasket bolt 36 is screwed on the first connecting seat 30 for pressing the F-type limit clamp 35 downward.

[0047] The hand-cranked threaded rod 25 is passed through the positioning hole on the first connecting seat 30 and then screwed into the threaded hole on the second connecting seat 31 until the annular groove 34 is aligned with the recess 33. Then, the F-type limit clamp 35 is inserted downward into the recess 33 and completely covers the annular groove 34. Finally, the locking gasket bolt 36 is tightened to tighten the F-type limit clamp 35. In this way, the hand-cranked threaded rod 25 and the first connecting seat 30 are axially connected, thereby providing sufficient anti-slip effect for the hand-cranked threaded rod 25 during the subsequent cutting process, avoiding the cumbersome traditional method of installing the bearing.

[0048] In order to smoothly and accurately complete the top wall cutting process of the U-shaped side rail 4, the following features are specifically set:

[0049] The cross-cutting mechanism 10 includes a second cross beam 37, a slider knife seat 38 slidably arranged on the second cross beam 37, a push handle 39 fixedly arranged on one side of the slider knife seat 38, and a diamond rolling cutter 40 fixedly arranged below the slider knife seat 38. The second cross beam 37 is provided with a long slide groove 41 that runs through both sides thereof horizontally for avoiding the sliding of the push handle 39. The pointer bar 12 is fixedly arranged at the bottom of one end of the second cross beam 37. The two ends of the second cross beam 37 are fixedly embedded with second linear bearings 42 for sliding connection to the optical axis bracket 6. The second cross beam 37 is provided with a strip hole 43 that runs through the upper and lower sides thereof longitudinally. 0 Three guide holes are opened on the knife block, and the top of the diamond rolling cutter 40 is fixedly connected with a first adjusting screw 44 and two guide rods 45 that pass upward through the strip hole 43. The two guide rods 45 are symmetrically distributed on both sides of the first adjusting screw 44. The upper and lower sides of the second crossbeam 37 are provided with limiting slides 46 located in the strip hole 43, and the outer side of each limiting slide 46 is provided with a first knurled nut 47 screwed on the first adjusting screw 44. The top of the positioning support seat 14 is provided with a rolling cutter groove 48 for the diamond rolling cutter 40 to be embedded, and the two ends of the rolling cutter groove 48 are respectively connected to the upper ends of the two side knife grooves 24.

[0050] The first adjusting screw 44 is driven to move up and down by rotating the upper and lower first knurled nuts 47, thereby adjusting the longitudinal height of the diamond rolling cutter 40, so that the blade of the diamond rolling cutter 40 can be embedded in the rolling cutter groove 48 on the top of the positioning support seat 14 during the translation process, and finally the two first knurled nuts 47 are appropriately tightened (just keep the first adjusting screw 44 from falling at the current height, and it is forbidden to lock it, otherwise it will affect the upper and lower limit slide plates 46 to drive the slider knife seat 38 to translate) to lock the current height of the diamond rolling cutter 40;

[0051] The cross-cutting mechanism 10 is moved on the optical axis bracket 6 by the push handle 39 until it moves to the target cutting position. Before cutting, the diamond rolling cutter 40 is moved close to the U-shaped side rail 4 on the positioning support seat 14 by the push handle 39, and the starting position of the diamond rolling cutter 40 is aligned with the top of the broken groove cut on the side wall of the U-shaped side rail 4 in the previous step. Then the push handle 39 is quickly pushed to drive the diamond rolling cutter 40 below through the slider tool holder 38 to slide across the bottom of the U-shaped side rail 4. In this process, the diamond rolling cutter 40 passes through the rolling cutter groove 48 and cuts off the top wall of the U-shaped side rail 4 at the same time, thereby completing the fixed-length and flush cutting of the U-shaped side rail 4.

[0052] In order to smoothly pull the U-shaped side rail 4 and accurately position the scale, the following features are specifically set:

[0053] The front end traction mechanism 8 includes a third cross beam 49, a second adjusting screw 50 vertically arranged in the middle of the third cross beam 49, an L-shaped upper clamping strip 51 fitted on one side of the third cross beam 49, an L-shaped lower clamping strip 52 fitted on the outside of the L-shaped upper clamping strip 51, and a knob screw 53. A wedge-shaped slide bar 54 is arranged on both sides of the long side of the L-shaped upper clamping strip 51, a first wedge-shaped slide groove 55 for matching the corresponding wedge-shaped slide bar 54 is formed in the middle of one side of the third cross beam 49, and the inner side of the long side of the L-shaped lower clamping strip 52 is provided with a wedge-shaped slide groove 55 for matching the corresponding wedge-shaped slide bar 54. A second wedge-shaped slot 56 is provided for cooperating with the corresponding wedge-shaped slot, the lower end of the second adjusting screw 50 is fixedly connected to the top of the short side of the L-shaped upper clamp 51, the knob screw 53 is axially connected to the top of the L-shaped upper clamp 51, and the top of the L-shaped lower clamp 52 is provided with a transverse support plate 57 which is threadedly matched with the knob screw 53, and the transverse support plate 57 is provided with a threaded hole for the knob screw 53 to pass through, and two second knurled nuts 58 are screwed on the second adjusting screw 50, which are respectively attached to the upper and lower sides of the third beam 49.

[0054] After inserting the front end of the U-shaped side rail 4 into the gap between the short sides of the L-shaped upper clamp 51 and the L-shaped lower clamp 52, the knob screw 53 is rotated to drive the L-shaped lower clamp 52 to rise until its short side faces upward to press the top wall of the U-shaped side rail 4 against the bottom of the L-shaped upper clamp 51. At this time, the third crossbeam 49 is dragged to slide on the optical axis bracket 6 to the farthest end and then stops. At this time, the front end of the U-shaped side rail 4 is just flush with the starting section of the scale of the ruler 11, and the side cutting mechanism 9 or the cross cutting mechanism 10 can determine the accurate fixed-length cutting position through their respective pointer bars 12 during the sliding process on the optical axis bracket 6.

[0055] The second adjusting screw 50 and the two second knurled nuts 58 are used to pre-adjust the lower edge height of the L-shaped upper clamp 51. The second adjusting screw 50 is driven to move up and down on the third cross beam 49 by loosening or tightening the second knurled nut 58 until the bottom surface height of the L-shaped upper clamp 51 is adjusted to be consistent with the top wall height of the U-shaped side strip.

[0056] In order to flexibly adjust the height position of the U-shaped side rail 4 into the optical axis bracket 6, the following features are specifically set:

[0057] The tail end support mechanism 7 includes a rolling shaft 59, a support rod 60 located below the rolling shaft 59, a plurality of narrow rollers 61 arranged on the support rod 60 and a width adjustment mechanism. Both ends of the rolling shaft 59 and the support rod 60 are connected to the optical axis bracket 6 through a cross-axis connector 62.

[0058] By tightening or loosening the corresponding cross-axis connecting pieces 62, the height positions of the rolling axis 59 and the support rod 60 on the optical axis bracket 6 can be flexibly adjusted, thereby ensuring that the top of the narrow roller 61, the top of the positioning support seat 14 and the bottom of the L-shaped upper clamp 51 are consistent in longitudinal height, thereby ensuring that the U-shaped side rail 4 is in a horizontal state as a whole in the optical axis bracket 6, and during the cutting process, the rolling axis 59 is in close contact with the top of the U-shaped side rail 4, thereby preventing the tail of the U-shaped side rail 4 from warping up during the cutting process.

[0059] In order to adapt to positioning support seats 14 of different widths and to adapt to the use of U-shaped side rails 4 of different groove widths, the following features are specifically set:

[0060] The width adjustment mechanism includes two hangers 63, two connecting rods 64 and two limiting clamps 65. The two hangers 63 are hung on the support rod 60, and all narrow rollers 61 are located between the two hangers 63. Both ends of each connecting rod 64 are connected with an anti-dropping bolt 66. A gap of the thickness of the hanger 63 is left between the cap end of the anti-dropping bolt 66 and the end of the connecting rod 64. The bottom of the hanger 63 is formed with an upwardly extending upper hanging slide hole 67 for hanging the support rod 60. The top of both ends of the hanger 63 is formed with a downwardly extending hanging groove 68 for the anti-dropping bolt 66 to enter. Both ends of each limiting clamp 65 are connected to the two connecting rods 64 through an elastic sleeve 69. The top of the limiting clamp 65 is formed with an avoidance hole 70 for avoiding the support rod 60 upward.

[0061] The width of a single narrow roller 61 corresponds to the minimum groove width of the U-shaped side rail 4. When cutting the U-shaped side rail 4 with the minimum groove width specification, the two connecting rods 64 together with the two limiting clamps 65 are lifted upward. During this process, the ends of the connecting rods 64 leave the hanging grooves 68 of the hanger 63 upward. At the same time, the two limiting clamps 65 avoid the support rod 60 through the avoidance holes 70 during the upward movement. Then, one of the connecting rods 64 is tilted downward to leave the hanger 63 in an inclined state, and then the unnecessary narrow rollers 61 on the support rod 60 are slid to both sides, leaving only one required narrow roller 61. Then, the previously separated connecting rod 64 is reset to the hanger 63. Finally, the two limiting clamps 65 are slid together until they are close to a reserved narrow roller 61. The two limiting clamps 65 are kept in the current position to limit the narrow roller 61 under the clamping action of their respective elastic sleeves 69. A number of elastic gaps are opened on the side walls of the elastic sleeves 69 to elastically hold the connecting rod 64. When it is necessary to cut the next batch of wider U-shaped side rails 4, more narrow rollers 61 can be moved between the two limiting clamps 65 in this way, and the positioning support seat 14 of the corresponding width can be replaced at the same time. The thickness of the L-shaped upper clamp 51 and the L-shaped lower clamp 52 only needs to match the U-shaped side rail 4 with the minimum groove width, and no replacement is required.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
