Description

Technical Field

[0001] The present invention relates to the technical field of wire threading construction devices, and particularly relates to a wire threading construction device for building engineering. Background Art

[0002] After the completion of building construction, it is necessary to install circuits in the building. When laying the circuits, in order to ensure the safe use of the wires, wire threading construction is carried out.

[0003] A wire threading construction device for building electrical engineering with the publication number of CN115864230A includes a support frame, a driving motor, a wire winding wheel, a diamond-shaped rod, a wire cable and a transmission mechanism. A driving motor is installed on the support frame, a diamond-shaped rod is connected to the output shaft of the driving motor, two wire winding wheels are clamped on the diamond-shaped rod, wire cables are wound on the wire winding wheels, and a transmission mechanism capable of automatically completing wire threading is connected to the support frame.

[0004] The above device uses the driving motor as the power source and can automatically push the wire cable, saving the trouble of manual operation. However, after the wire cable passes through the protective pipe, the staff needs to manually loosen the locking ring to remove the sleeve from the wire cable, then manually install the sleeve on the support frame, insert one end of the wire cable into the sleeve, and then tighten the locking ring to fix the wire cable before the next push of the wire cable can be carried out.

[0035] The following will describe each embodiment of the present invention in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0036] As Figures 1-3As shown in the figure, a wire threading construction device for construction engineering includes a support platform 1 and a sleeve 2. A wire feeding mechanism is arranged on the upper surface of the support platform 1. The wire feeding mechanism includes a first right-angle seat 4 fixedly connected to the upper surface of the support platform 1. A support rod is rotatably installed inside the first right-angle seat 4. A first wire winding roller 5 is sleeved on the outer surface of the support rod. A first stop block is fixedly connected to the outer surface of the support rod. A second stop block is threadedly connected to the outer surface of the support rod. The first stop block and the second stop block clamp the first wire winding roller 5. Two symmetrically arranged support seats 6 are fixedly connected to the upper surface of the support platform 1. The two support seats 6 are located on the left side of the first wire winding roller 5. A first rotating shaft 7 and a second rotating shaft 8 are rotatably installed between the two support seats 6. Wire feeding wheels 9 are fixedly connected to the outer surfaces of the first rotating shaft 7 and the second rotating shaft 8. One end of the support rod away from the first right-angle seat 4 is provided with a thread adapted to the second stop block. After unscrewing the second stop block from the support rod, the first wire winding roller 5 can be slid off the support rod. Then, the cable can be wound around the first wire winding roller 5. After reinstalling the first wire winding roller 5 with the cable on the support rod, one end of the cable is passed through between the two wire feeding wheels 9, and then the cable can be pushed by starting the driving mechanism.

[0037] As Figures 1-3 shown, a cutting mechanism is also arranged on the upper surface of the support platform 1. The cutting mechanism is located between the wire feeding wheel 9 and the sleeve 2. The cutting mechanism includes a first housing 10 fixedly connected to the upper surface of the support platform 1. Two symmetrically arranged reciprocating lead screws 11 are rotatably installed inside the first housing 10. The close ends of the two reciprocating lead screws 11 are fixedly connected through a round block. Threaded seats 12 are threadedly connected to the outer surfaces of the two reciprocating lead screws 11. The threaded seats 12 are slidably connected to the first housing 10. Cutting knives 13 are fixedly installed on the opposite sides of the two threaded seats 12 close to each other. When the reciprocating lead screw 11 rotates, it can drive the threaded seat 12 to reciprocate along the reciprocating lead screw 11. The movement of the threaded seat 12 can drive the cutting knife 13 to move accordingly. When the two cutting knives 13 move into contact with each other, the cable between the two cutting knives 13 can be cut off.

[0038] As Figures 1-3As shown in the figure, a driving mechanism is further provided on the upper surface of the support table 1. The driving mechanism includes a second right-angle seat 14 fixedly installed on the upper surface of the support table 1. A servo motor 15 is installed on the second right-angle seat 14. The output end of the servo motor 15 is fixedly connected to a driving shaft 16. A first one-way bearing 17 is installed on the outer surface of the driving shaft 16. A first synchronous pulley 18 is installed on the first one-way bearing 17. A second synchronous pulley 19 is fixedly connected to the outer surface of the support rod. The second synchronous pulley 19 and the first synchronous pulley 18 are connected by a first synchronous belt. The servo motor 15 has a self-locking function. When controlling the servo motor 15 to rotate forward, the servo motor 15 can drive the driving shaft 16 to rotate forward. The forward rotation of the driving shaft 16 can drive the first one-way bearing 17 and the first synchronous pulley 18 to rotate correspondingly as a whole. The rotation of the first synchronous pulley 18 can drive the second synchronous pulley 19 and the first wire winding roller 5 to rotate. The rotation of the first wire winding roller 5 can release the cable.

[0039] As Figure 2 and Figure 3 As shown in the figure, a second one-way bearing 20 is installed on the outer surface of the driving shaft 16. A third synchronous pulley 21 is installed on the second one-way bearing 20. A fourth synchronous pulley 22 is fixedly connected to the outer surface of the second rotating shaft 8. The fourth synchronous pulley 22 and the third synchronous pulley 21 are connected by a second synchronous belt. A third rotating shaft 23 is rotatably installed on one of the support seats 6. Fifth synchronous pulleys 24 are fixedly connected to the outer surfaces of the third rotating shaft 23 and the second rotating shaft 8. The two fifth synchronous pulleys 24 are connected by a third synchronous belt. Gears 25 are fixedly connected to the outer surfaces of the third rotating shaft 23 and the first rotating shaft 7. The two gears 25 are meshed with each other. The second one-way bearing 20 and the first one-way bearing 17 rotate in the same direction. Therefore, the forward rotation of the driving shaft 16 can drive the second one-way bearing 20 and the third synchronous pulley 21 to rotate correspondingly as a whole. The rotation of the third synchronous pulley 21 can drive the fourth synchronous pulley 22, the second rotating shaft 8, the third rotating shaft 23, the first rotating shaft 7, etc. to rotate simultaneously. The rotation of the first rotating shaft 7 and the second rotating shaft 8 can drive the two wire feeding wheels 9 to rotate towards the sleeve 2 at the same time. The rotation of the two wire feeding wheels 9 towards the sleeve 2 can push the cable.

[0040] As Figure 2 and Figure 3As shown, a third one-way bearing 50 is mounted on the outer surface of the drive shaft 16, and a sixth synchronous pulley 51 is mounted on the third one-way bearing 50. A seventh synchronous pulley 52 is fixedly connected to the outer surface of one of the reciprocating lead screws 11. The seventh synchronous pulley 52 and the sixth synchronous pulley 51 are connected by a fourth synchronous belt for transmission. The rotation directions of the third one-way bearing 50 and the second one-way bearing 20 are opposite. Thus, when the drive shaft 16 rotates forward, it will only drive the third one-way bearing 50 to rotate idly, and the sixth synchronous pulley 51 will not rotate correspondingly. Furthermore, during the process of pushing the cable, the cutting knife 13 will not move. After the cable is pushed, control the servo motor 15 to reverse. The servo motor 15 can drive the drive shaft 16 to rotate in the reverse direction. The reverse rotation of the drive shaft 16 can drive the third one-way bearing 50 and the sixth synchronous pulley 51 as a whole to rotate correspondingly. The rotation of the sixth synchronous pulley 51 can drive the seventh synchronous pulley 52 and the two reciprocating lead screws 11 to rotate. The rotation of the two reciprocating lead screws 11 can drive the threaded seat 12 to reciprocate along the reciprocating lead screw 11. The movement of the threaded seat 12 can drive the cutting knife 13 to move correspondingly. When the two cutting knives 13 move into contact with each other, the cable between the two cutting knives 13 can be cut. After the cable is cut, when the reciprocating lead screw 11 continues to rotate to drive the threaded seat 12 to move in the reverse direction to the initial state, turn off the servo motor 15.

[0041] As Figures 1-4 and Figure 7 As shown, two semi-circular covers 49 are arranged outside the sleeve 2, and the semi-circular covers 49 and the clamping plate 44 are connected by a connecting plate 48. A second sliding groove for the horizontal sliding of the connecting plate 48 is opened inside the sleeve 2. The upper surface of the support table 1 is fixedly connected with a first support plate 38. A support mechanism for supporting the sleeve 2 is arranged on the upper surface of the first support plate 38. The support mechanism includes a Z-shaped plate 42 fixedly connected to the upper surface of the first support plate 38. Two third support plates 43 are fixedly connected to the upper surface of the Z-shaped plate 42. Connecting seats 26 are fixedly connected to the mutually remote surfaces of the two third support plates 43. Two bent rods 27 are fixedly connected to each side of the two connecting seats 26 close to the sleeve 2, and the bent rods 27 are located between the second housing 46 and the semi-circular cover 49. The bent rod 27 is a column with horizontal ends and an outwardly inclined middle part. When pulling the sleeve 2 back to its original position, the bent rod 27 will first be inserted between the second housing 46 and the semi-circular cover 49. Then, when the semi-circular cover 49 gradually moves to the bent position of the bent rod 27, the bent rod 27 will gradually drive the semi-circular cover 49 to move towards the center and expand the semi-circular cover 49, thereby enabling the centering positioning of the semi-circular cover 49 and the sleeve 2.

[0042] As Figures 4-6 and Figures 8-10As shown, two symmetrically arranged second shells 46 are fixedly connected to the outer surface of the sleeve 2. Two clamping plates 44 are movably arranged inside the sleeve 2. One end of each of the two clamping plates 44 away from each other is fixedly connected with an insertion post 45. And the end of the insertion post 45 away from the clamping plate 44 slides through the sleeve 2 and extends into the interior of the second shell 46. The outer surfaces of the parts of the two insertion posts 45 located inside the two second shells 46 are fixedly connected with first rectangular plates 29. First springs 30 are fixedly connected to the outer surfaces of the two first rectangular plates 29. And the other end of the first spring 30 is fixedly connected to the inner wall of the second shell 46. A limit release mechanism is arranged inside each of the two second shells 46. And the limit release mechanism is connected to the pulling-back mechanism. The limit release mechanism includes a second rectangular plate 31 fixedly connected to the upper surface of the insertion post 45. A first wedge-shaped block 32 is fixedly connected to the side of the second rectangular plate 31 close to the sleeve 2. A second spring 34 is fixedly connected to the inside of the second shell 46. One end of the second spring 34 is fixedly connected to a third rectangular plate 33. And the third rectangular plate 33 is slidably connected to the inside of the second shell 46. The second shell 46 is provided with a third sliding groove for the horizontal sliding of the third rectangular plate 33. A second wedge-shaped block 35 adapted to the first wedge-shaped block 32 is fixedly connected to the upper surface of the third rectangular plate 33. A retaining bar 36 is fixedly connected to the side of the second wedge-shaped block 35 away from the second spring 34. Anti-slip pads 47 are installed inside each of the two clamping plates 44. By providing the anti-slip pads 47, the friction between the clamping plates 44 and the cable can be increased, and the fixing effect can be improved. A first sliding groove for the horizontal sliding of the insertion post 45 is provided inside the sleeve 2. After one end of the cable passes through the protective tube, the worker holds the outer shell 3 by hand and activates the pulling-back mechanism to pull the third rectangular plate 33 to move. The movement of the third rectangular plate 33 can drive the second wedge-shaped block 35 to move accordingly and compress the second spring 34. The movement of the second wedge-shaped block 35 can squeeze the first wedge-shaped block 32 to move outwards. The movement of the first wedge-shaped block 32 can drive the insertion post 45 and the clamping plate 44 to move accordingly and compress the first spring 30. The clamping plate 44 moves outwards to loosen the cable. When the third rectangular plate 33 moves to the maximum extent, the second wedge-shaped block 35 no longer contacts the first wedge-shaped block 32. At this time, under the action of the first spring 30, the first wedge-shaped block 32 will move to abut against the retaining bar 36, so as to be able to limit the second wedge-shaped block 35, and further prevent the clamping plate 44 from re-clamping the cable due to the loosening of the steel wire rope 41 during the process of pulling the sleeve 2 to move. When the sleeve 2 moves until the bent rod 27 is inserted between the second shell 46 and the semi-circular cover 49, during the continuous pulling of the sleeve 2, the bent rod 27 will gradually drive the semi-circular cover 49 to move towards the center and expand the semi-circular cover 49. The outward movement of the semi-circular cover 49 can drive the clamping plate 44 to move accordingly again. When the sleeve 2 returns to the initial position, the semi-circular cover 49 will move outwards to the maximum extent. At this time, the mutually approaching surfaces of the first wedge-shaped block 32 and the second wedge-shaped block 35 are flush and there is a gap between them, so as to ensure that when clamping the cable,The first wedge block 32 will not block the second wedge block 35.,

[0043] As Figures 1-3 shown, a pulling-back mechanism for pulling the sleeve 2 back to its original position is arranged on the right side of the first support plate 38. The pulling-back mechanism includes a support frame fixedly connected to the upper surface of the support table 1. A double-shaft motor 37 is installed on the support frame. Second winding rollers 40 are fixedly installed at both output ends of the double-shaft motor 37. Second support plates 39 are rotatably installed at the mutually remote ends of the two second winding rollers 40, and the second support plates 39 are fixedly connected to the right side surface of the first support plate 38. Steel wire ropes 41 are wound around the two second winding rollers 40, and the other ends of the steel wire ropes 41 slide through one side surface of the second housing 46 and are fixedly connected to the third rectangular plate 33. The double-shaft motor 37 has a self-locking function. A circular hole for the second housing 46 to slide is formed inside the second housing 46. When the double-shaft motor 37 is started, the double-shaft motor 37 can drive the second winding roller 40 to rotate. When the second winding roller 40 is driven to rotate forward, the steel wire rope 41 can be wound. When the second winding roller 40 is driven to rotate reversely, the steel wire rope 41 can be released. While releasing the steel wire rope 41, the cable is pushed towards the sleeve 2. Releasing the steel wire rope 41 will release the tension limit on the sleeve 2. The third rectangular plate 33 and the second wedge block 35 will move away from the support table 1. Under the action of the elastic force of the first spring 30, the semi-circular cover 49 will also gradually slide along the bent part of the bent rod 27 away from the support table 1. When the second wedge block 35 moves away from the support table 1 to the maximum extent, the first wedge block 32 and the clamping plate 44 will also move towards the cable to the maximum extent, so that the two clamping plates 44 will clamp the cable. At this time, the inclined surface of the first wedge block 32 is in contact with the inclined surface of the second wedge block 35. After that, continuing to push the cable can make the sleeve 2 and the semi-circular cover 49 separate from the bent rod 27 and enter the interior of the protection tube.

[0044] As Figure 2 shown, a housing 3 is fixedly connected to the left end of the sleeve 2, and the sleeve 2 and the two semi-circular covers 49 are both located inside the housing 3. Fixed pulleys 28 for guiding and supporting the steel wire rope 41 are rotatably installed on the mutually approaching surfaces of the two third support plates 43.

[0045] Working principle: When pushing the cable, first pass one end of the cable through between the two wire feeding wheels 9, and then control the forward rotation of the servo motor 15 and the reverse rotation of the dual-axis motor 37. The forward rotation of the servo motor 15 can push the cable to move in the direction of the sleeve 2, and the reverse rotation of the dual-axis motor 37 can release the steel wire rope 41. Releasing the steel wire rope 41 will relieve the tension limit on the sleeve 2, and the third rectangular plate 33 and the second wedge block 35 will move away from the support table 1. Under the action of the elastic force of the first spring 30, the semi-circular cover 49 will also gradually slide along the bent part of the bent rod 27 in the direction away from the support table 1. When the second wedge block 35 moves to the maximum extent away from the support table 1, the first wedge block 32 and the clamping plate 44 will also move to the maximum extent in the direction of the cable, so that the two clamping plates 44 will clamp the cable. After that, continue to push the cable to make the sleeve 2 and the semi-circular cover 49 disengage from the bent rod 27 and enter the inside of the protective tube.

[0046] After passing one end of the cable through the protective tube, one of the staff moves here, holds the housing 3 by hand and operates the passed cable. The other staff closes the servo motor 15 at the initial position and controls the forward rotation of the dual-axis motor 37. The forward rotation of the dual-axis motor 37 can wind up the steel wire rope 41. Thus, the steel wire rope 41 will pull the third rectangular plate 33 to move. The movement of the third rectangular plate 33 can drive the second wedge block 35 to move correspondingly and compress the second spring 34. The movement of the second wedge block 35 can squeeze the first wedge block 32 to move outwards. The movement of the first wedge block 32 can drive the plug post 45 and the clamping plate 44 to move correspondingly and compress the first spring 30. The outward movement of the clamping plate 44 can loosen the cable. When the third rectangular plate 33 moves to the maximum extent and the second wedge block 35 no longer contacts the first wedge block 32, at this time, under the action of the first spring 30, the first wedge block 32 will move to abut against the stop bar 36, so as to be able to limit the second wedge block 35, and further prevent the clamping plate 44 from re-clamping the cable due to the loosening of the steel wire rope 41 during the process of pulling the sleeve 2 to move. Then continue to wind up the steel wire rope 41 to drive the third rectangular plate 33 and the sleeve 2 and other components to return along the original path. When the sleeve 2 moves to the position where the bent rod 27 is inserted between the second housing 46 and the semi-circular cover 49, during the process of continuing to pull the sleeve 2, the bent rod 27 will gradually drive the semi-circular cover 49 to move towards the center and expand the semi-circular cover 49. The outward movement of the semi-circular cover 49 can drive the clamping plate 44 to move correspondingly again. When the sleeve 2 returns to the initial position, the semi-circular cover 49 will move outwards to the maximum extent. Then control the reverse rotation of the servo motor 15 to cut the cable, and then perform the above operations to carry out the next threading.
