Description

Technical Field

[0001] The invention relates to the technical field of electric power construction threading, in particular to an automatic threading device for building electrical construction. Background Art

[0002] In the process of building electrical construction, the application of automatic threading equipment has greatly improved the construction efficiency and accuracy. However, the automatic threading equipment in the prior art faces a technical challenge when handling wires of different sizes. Due to the diversity of wire diameters, from small communication lines to thick power lines, when wires of different specifications are inserted into the equipment, they often have low threading efficiency due to size mismatch, and may even damage the wires or equipment.

[0003] Specifically, the thickness of the wire diameter directly affects the resistance value, transmission efficiency and mechanical strength of wires and cables. When designing a circuit, it is necessary to select the appropriate wire diameter based on the current size and the characteristics of the equipment. However, in actual construction, due to the variety of wire specifications, automatic threading equipment often finds it difficult to adapt to such changes.

[0004] Traditional automatic threading equipment is usually designed with fixed threading channels and parameter settings, which leads to obvious limitations when processing wires with large differences in wire diameter. When the wire diameter is small, it may not be effectively fixed due to the large channel, causing the wire to easily deviate or fall off during the threading process; when the wire diameter is large, it may not pass smoothly due to the small channel, and even cause the equipment to get stuck or damaged.

[0005] Chinese patent authorization announcement number CN116526371B is a wire threading construction device for building electrical engineering, which is connected to the handheld housing, a joint, a fixed airbag, a connecting column and a fixed ring, etc. The joint is connected to the handheld housing, the outer wall of the connecting column is connected to a fixed airbag, and one end of the connecting column is connected to a fixed ring for fixing the end of the wire. The fixed airbag can be inserted into the wire tube, and the fixed airbag can be pushed to slide along the inner wall of the wire tube by inflating with an air pump to pull the end of the wire into the wire tube for threading. The present invention ties one end of the wire to the fixed ring, then inserts the fixed airbag into the wire tube, and then inflates the handheld housing with air through an air pump. The fixed airbag can be pushed by air to slide along the inner wall of the wire tube, thereby driving one end of the wire to move inside the wire tube to complete the automatic threading work, thereby improving work efficiency and preventing the end of the wire from being stuck in the wire tube.

[0006] However, in actual use, due to the different thicknesses of the wires, when the airbag is propped up and the thicker wires are pressed against the inside of the wire tube and moved, greater friction will be generated between the wires and the inner wall of the wire tube, affecting the smooth movement of the wires and possibly damaging the surface of the wires.

[0036] The left end of the casing 1 is provided with a connection port for connecting an external air pump, and the inside of the casing 1 is provided with a through port for gas to pass through. The outside of the positioning disk 31 is provided with displacement grooves for sliding of a plurality of moving blocks 33, and the moving blocks 33 can stably slide along the displacement grooves when sliding. When it is necessary to thread the wire into the inside of the casing 1, the wire is first inserted through the threading hole 2 provided on the casing 1. In this process, the user rotates the rotating disk 32, and when the rotating disk 32 rotates on the positioning disk 31, it can drive the plurality of moving blocks 33 to move relatively close to each other along the displacement grooves provided on the positioning disk 31, and when the moving blocks 33 move, they can drive the abutment wheels 34 to clamp and limit the wire, and can limit and clamp wires of different thicknesses, and the wire can contact the lubrication block 35 when passing through the abutment wheels 34.

[0037] See also Figure 3-Figure 5 As shown, the limited lubrication mechanism 3 also includes a toothed disc 36, a rotating rod 37, a first gear 38 and a toothed plate 39; the toothed disc 36 is arranged at the left end of the rotating disc 32 and is located on one side of the threading hole 2; the rotating rod 37 is arranged at the top of the positioning disc 31 and has a plurality of teeth; the toothed plate 39 is arranged at the top of the moving block 33 and meshes with the first gear 38; the first gear 38 has a plurality of teeth and is respectively arranged on the outside of the rotating rod 37, and the first gear 38 meshes with the gear ring, and when the toothed disc 36 rotates, it can drive the meshed first gear 38 to rotate.

[0038] The toothed disc 36 is fixedly connected to the rotating disc 32. When the rotating disc 32 rotates, the toothed disc 36 can be driven to rotate synchronously. When the toothed disc 36 rotates, the multiple meshing first gears 38 can be rotated. Since the first gears 38 are meshed with the toothed plate 39, and the toothed plate 39 is fixedly connected to the moving block 33, when the first gear 38 rotates, the multiple moving blocks 33 can be driven to move relatively close.

[0039] See also Figure 4-Figure 7 As shown, the limited lubrication mechanism 3 also includes a rotating dial 391 and a sliding block 392; the rotating dial 391 is arranged at the bottom of the moving block 33 and is located on both sides of the abutment wheel 34; a slide groove is opened on the top of the moving block 33; the sliding block 392 is slidably arranged above the slide groove and is located above the abutment wheel 34; when the moving block 33 descends, it can drive the sliding block 392 to move synchronously.

[0040] When the thread body passes through the position of the abutment wheel 34 and is threaded, when the abutment wheel 34 contacts the thread body and rotates, it can drive the rotating dial 391 to rotate synchronously. When the rotating dial 391 rotates, it can drive the sliding block 392 to slide downward intermittently.

[0041] See also Figure 6 and Figure 7 As shown, the position limiting lubrication mechanism 3 also includes a positioning plate 393, an elastic traction rope 394, a locking rod 395 and a contact block 396; the positioning plate 393 is arranged on the top of the moving block 33 and is located above the sliding block 392; the elastic traction rope 394 is arranged on the top of the positioning plate 393, and the elastic traction rope 394 is connected to the sliding block 392; the contact block 396 is arranged on one side of the sliding block 392 and is located above the rotating dial 391; the locking rod 395 is arranged on the top of the sliding block 392, and the locking rod 395 is used to press the lubrication block 35 against the sliding block 392.

[0042] The sliding block 392 is provided with a circular hole for the lubricating block 35 to pass through, and the locking rod 395 can press the lubricating block 35 against the inside of the circular hole by spiral rotation. The lubricating block 35 is cylindrical, and the material of the lubricating block 35 can be selected as a solid lubricant or a candle. In order to reduce production costs, the material of the lubricating block 35 is preferably a candle, and the candle can lubricate the wire body when it contacts the wire body. When the rotating dial 391 rotates, it can contact the contact block 396, and when in contact, it can drive the contact block 396 and the sliding block 392 to descend, so that the sliding block 392 drives the lubricating block 35 to descend. The lubricating block 35 is contacted and lubricated to the wire body, while avoiding excessive lubrication, and the elastic traction rope 394 can be driven to be stretched during the descent process. When the rotating dial 391 is not in contact with the contact block 396, the elastic traction rope 394 can pull the sliding block 392 to reset to rise, so that the lubricating block 35 can intermittently contact and lubricate the wire body.

[0043] See also Figure 8-Figure 10 As shown, the auxiliary traction flipping mechanism 4 includes a linear drive 41, a screw rod 42, a limiting block 43 and a displacement block 44; the linear drive 41 is arranged inside the housing 1 and below the automatic winding mechanism 5; the screw rod 42 is arranged at the output end of the linear drive 41; the limiting blocks 43 have a pair and are respectively arranged on the inner wall of the housing 1, and the limiting blocks 43 are located on both sides of the linear drive 41; the displacement block 44 is slidably arranged on the limiting block 43 and is threadedly connected with the screw rod 42.

[0044] When the wire body passes through the abutment wheel 34, the user continues to thread the wire body and processes the wire body to pass through one side of the displacement block 44. Then the linear drive 41 drives the screw rod 42 to rotate, and the screw rod 42 can drive the displacement block 44 to slide along the limiting block 43 when rotating, and in this process, the wire body can be driven to move, and the initial traction of the wire body is completed at this time.

[0045] See also Figure 8-Figure 10 As shown, the auxiliary traction flipping mechanism 4 also includes a flipping block 45, a clamping cylinder 46 and an abutment block 47; the flipping block 45 is rotatably arranged above the displacement block 44 and is located inside the casing 1; the clamping cylinder 46 has a pair and is respectively arranged on the top of the flipping block 45; the abutment block 47 is slidably arranged at the output end of the clamping cylinder 46, and when the abutment block 47 moves, it can abut the wire body located inside the threading hole 2.

[0046] The outside of the housing 1 is provided with an observation window located on one side of the limit lubrication mechanism 3. The observation window is preferably made of glass, and the position of the wire body in the clamping cylinder 46 can be observed. When the wire body is on one side of the displacement block 44, the clamping cylinder 46 drives and drives the abutment block 47 to move. The contact surface between the abutment block 47 and the wire body is semicircular, and the abutment block 47 is preferably made of rubber. The abutment block 47 can clamp the wire body on the displacement block 44. At this time, the wire body is in a state of being fixed by the abutment block 47, so that the movement of the displacement block 44 can pull the wire body for traction movement.

[0047] See also Fig. 9 As shown, the auxiliary traction flipping mechanism 4 also includes a limiting plate 48, an extension portion 49 and a contact portion 491; the limiting plate 48 has a pair and is respectively arranged at the right end of the displacement block 44, and the limiting plate 48 is located on one side of the flipping block 45; the extension portion 49 has a pair and is respectively arranged on the top of the flipping block 45; the contact portion 491 is arranged above the limiting plate 48 and is located inside the casing 1. When the extension portion 49 moves and abuts against the contact portion 491, it can drive the flipping portion to perform a flipping motion.

[0048] When the wire is pulled by the displacement block 44, the limiting plate 48 can abut against the right side of the flipping part, which can prevent the flipping part from flipping to the right when the wire is pulled. When the displacement block 44 drives the flipping part to move to the position of the contact part 491, the extension part 49 provided on the flipping block 45 can contact the contact part 491, and when in contact, the flipping part can be driven to flip, so that the wire clamped on the abutment block 47 is flipped at the same time, and the clamped wire can be automatically flipped toward the upper side of the housing 1, which is convenient for the subsequent pulling action of the wire without manual pulling of the wire.

[0049] See also Fig.10 and Fig.11 As shown, the automatic winding mechanism 5 includes an auxiliary traction portion 51 and a contact roller 52; a avoidance hole for the wire body to pass through is opened on the top of the casing 1; the auxiliary traction portion 51 is arranged on the top of the casing 1 and is located below the avoidance hole; the contact roller 52 has a pair and is slidably arranged on the top of the casing 1, and the contact roller 52 is located above the avoidance hole.

[0050] The auxiliary traction part 51 includes a rotating roller 511 and a rotating driver 512. The rotating roller 511 has a pair of rotating rollers 511 and is respectively rotatably arranged inside the housing 1. The pair of rotating rollers 511 are both located below the avoidance hole. The rotating driver 512 is arranged outside the housing 1 and connected to one of the rotating rollers 511. The two rotating rollers 511 are both provided with anti-slip blocks outside. The anti-slip blocks can increase the friction between the rotating rollers 511 and the wire body to ensure the stable traction of the wire body on the rotating rollers 511. When the rotating roller 511 connected to the rotating driver 512 rotates, the anti-slip block will come into contact with the anti-slip block arranged on the other rotating roller 511, and the other rotating roller 511 is driven to rotate by friction. When the flip block 45 drives the wire body to flip and is located between the two rotating rollers 511, the rotating roller 511 rotates and pulls the flipped wire body upward toward the position of the avoidance hole, and then the pulled wire body can be located between the two contact rollers 52. There is no need to manually pull the wire body.

[0051] See also Fig.10 and Fig.11 As shown, the automatic winding mechanism 5 also includes a pulling tooth block 53, a contact gear 54 and a driven component 55; the pulling tooth plate 39 is slidably set on the top of the casing 1 and is located on one side of the contact roller 52; the contact gear 54 is rotatably set on the top of the casing 1 and has a pair, and the contact gear 54 is located on both sides of the avoidance hole; the driven component 55 is slidably set on the top of the casing 1 and meshes with the contact gear 54, and when the pulling tooth block 53 is moved, it can drive the contact gear 54 to rotate, and when the contact gear 54 rotates, it can drive the driven component 55 to slide.

[0052] One of the contact rollers 52 is fixedly connected to the pulling tooth block 53, and the other contact roller 52 is fixedly connected to the driven component 55. When the wire body is located between the two contact rollers 52. When the pulling tooth block 53 is pushed to the left, the pulling tooth block 53 can drive the contact gear 54 to rotate. When the contact gear 54 rotates, the meshing driven component 55 can be moved in the direction close to the pulling tooth block 53, so that when the pulling tooth block 53 moves to the right, the driven component 55 can be driven to approach relatively through the contact gear 54. When the pulling tooth block 53 and the driven component 55 are relatively close, the contact roller 52 can be driven to move synchronously, and then the position of the contact roller 52 can be adjusted, and the wire bodies of different thicknesses can be pulled and moved, ensuring the stable traction of the wire body. And in this process, there is no need to manually find and pull the wire body.

[0053] See also Figure 10-12 As shown, the automatic winding mechanism 5 also includes a setting frame 56, a storage roller 57, a connecting member 58 and a tightening portion 59; the setting frame 56 is installed on the top of the casing 1 and is located above the avoidance hole; the storage roller 57 is rotatably installed below the setting frame 56; the connecting block is arranged on the storage roller 57 and is located above the avoidance hole; the tightening portion 59 is rotatably arranged on the right side of the connecting member 58, and the tightening portion 59 is threadedly connected to the connecting member 58, and the tightening portion 59 can be screwed into the interior of the connecting member 58 by spiral screwing and tightening the wire body.

[0054] The storage roller 57 can be provided with a rotary driver 512 for driving the storage roller 57 to rotate. When the rotary driver 512 rotates, the storage roller 57 can be driven to rotate. When the wire passes through the contact roller 52 and extends to the position of the connecting member 58, the user rotates the pressing part 59 and presses the wire against the connecting member 58, and the pulling action of the wire is completed. Then, the rotary driver 512 is started and drives the storage roller 57 to rotate. Automatic threading of the wire is realized, and no manual intervention is required when the wire is threaded in the housing 1, thereby improving the threading efficiency.

[0055] Working principle: When the wire is threaded into the housing 1, the wire must first be introduced through the threading hole 2 on the housing 1. At this time, the rotating disk 32 is rotated. Since the rotating disk 32 is fixedly connected to the toothed disk 36, the rotation of the toothed disk 36 will drive the first gears 38 meshing therewith to rotate. The meshing action of the first gear 38 and the toothed plate 39 will cause the moving blocks 33 fixedly connected to the toothed plate 39 to approach each other. When the wire passes through the abutment wheel 34, the rotation of the abutment wheel 34 will drive the rotating dial wheel 391 to rotate synchronously, thereby driving the sliding block 392 to intermittently descend. The contact between the rotating dial wheel 391 and the contact block 396 will drive the sliding block 392 and the lubricating block 35 to descend, contact lubrication of the wire, and at the same time, the elastic traction rope 394 is stretched. When the rotating dial wheel 391 is separated from the contact block 396, the elastic traction rope 394 is reset, pulling the sliding block 392 to rise, and realizing intermittent lubrication of the lubricating block 35. Subsequently, the user continues to push the wire body through the displacement block 44, and the linear drive 41 drives the screw rod 42 to rotate, driving the displacement block 44 to slide along the limiting block 43, and initially pulling the wire body. When the wire body reaches one side of the displacement block 44, the clamping cylinder 46 drives the abutment block 47 to move. The abutment block 47 is made of semicircular rubber material and clamps the wire body on the displacement block 44. At this time, the movement of the displacement block 44 will pull the wire body for traction. The limiting plate 48 prevents the wire body from causing the flipping part to flip during the traction process. When the displacement block 44 drives the flipping part to move to the contact part 491, the extension part 49 on the flipping block 45 contacts the contact part 491, causing the flipping part to flip, and the wire body flips to the top of the housing 1, which is convenient for subsequent traction. The flipped wire body is located between the two rotating rollers 511, and the rotating rollers 511 are driven to rotate mutually by the friction between the anti-sliding blocks, pulling the wire body to the avoidance hole position. Subsequently, the wire body is located between the two contact rollers 52. When the pull gear block 53 is pushed, the contact gear 54 rotates, driving the driven component 55 to move in the direction of the pull gear block 53, so as to adjust the position of the contact roller 52 to adapt to the traction of wires of different thicknesses. When the wire passes through the contact roller 52 and extends to the connecting member 58, the rotating pressing part 59 presses the wire against the connecting member 58 to complete the traction action. Finally, the rotary driver 512 is started, driving the storage roller 57 to rotate, so as to realize automatic threading of the wire. The whole process does not require manual intervention, which improves the threading efficiency.

Therefore, the protection scope of the present invention shall be subject to the attached claims.
