Description

Technical Field

[0001] This utility model belongs to the technical field of wire and cable construction, and specifically relates to a wire laying device used in the wire and cable construction process. Background Technology

[0002] Cables are wire products used to transmit electrical energy, information, or realize the conversion of electromagnetic energy, and are widely used in power, communication, industrial control and other fields. In actual construction, especially for large-diameter cables, they are usually pre-wound on cable reels (or spools) for storage and transportation. The cable reels need to be moved to the designated location, and the cables are released from the reels and led to the laying path by a cable release device.

[0003] When cables are released from the reel, they are usually in a bent or twisted state, making it difficult to keep them straight. This is not conducive to subsequent laying and wiring operations, especially in the construction of long-distance, large-section cables. The initial bending state of the cable may exacerbate the construction difficulty, leading to cable stacking, jamming, or misalignment, which further affects construction efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to provide a wire laying device for use in the construction of wires and cables, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A wire-laying device used in the construction of electrical wires and cables includes a flattening component and a base. Two positioning auxiliary frames are mounted on the top of the base. Two support frames are fixedly connected to the top of the base. Each support frame has an internal mounting plate. A wire-laying roller connected to the two mounting plates by bolts is provided. Two support rods are fixedly connected to the top of the base. Two fixed columns are fixedly connected between the two support rods. Reciprocating blocks are slidably connected to the outside of the two fixed columns. A flattening component is provided inside the reciprocating blocks. A lateral limiting component is provided outside the reciprocating blocks. An auxiliary component includes damping rings fixedly connected to the inside of the left and right sides of the reciprocating blocks. Rectangular inserts are inserted into the inside of each of the two damping rings.

[0006] In a preferred embodiment of this utility model, the flattening assembly includes a rotary motor fixedly connected to the right side of the right support rod. A reciprocating screw is fixedly connected to the output end of the rotary motor. A functional block is rotatably connected inside the reciprocating block. A fixed frame is fixedly connected to the top of the reciprocating block. A lifting screw is threadedly connected inside the fixed frame. A lifting frame is rotatably connected to the bottom end of the lifting screw. A U-shaped mounting plate is slidably connected up and down inside the lifting frame. Two tension springs are provided between the top of the U-shaped mounting plate and the lifting frame. Seven flattening rollers are rotatably connected inside both the U-shaped mounting plate and the fixed frame.

[0007] In a preferred embodiment of this utility model, the U-shaped mounting plate and the flattening roller inside the fixed frame are arranged symmetrically from top to bottom, the two ends of the tension spring are fixed to the U-shaped mounting plate and the lifting frame, and the lifting frame is slidably connected to the inside of the fixed frame from top to bottom.

[0008] In a preferred embodiment of this utility model, the reciprocating screw passes through the reciprocating block and does not contact the reciprocating block, and the functional block is movably connected in the threaded groove of the reciprocating screw.

[0009] As a preferred embodiment of this utility model, the lateral limiting component includes two rectangular plates fixedly connected to the front and rear of the reciprocating block, and the number of the rectangular plates is four. The other two rectangular plates are fixedly connected to the front and rear of the fixed frame. The upper two rectangular plates have adjustment grooves inside, and the adjustment grooves are slidably connected to the limiting posts on the left and right sides.

[0010] In a preferred embodiment of this utility model, the diameter of the top end of the limiting post is larger than the diameter of the adjusting groove, and the upper rectangular plate and the corresponding position of the top end of the limiting post are provided with positioning grooves, and the limiting post is inserted into the positioning groove, and the bottom end of the limiting post passes through the adjusting groove and is inserted into the lower rectangular plate.

[0011] In a preferred embodiment of this utility model, a cleaning roller is fixedly connected to the end of the rectangular insert block away from the reciprocating block. The cleaning roller is in contact with the reciprocating screw, and an anti-collision groove is provided on the inner side of the support rod at the corresponding position of the cleaning roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The flattening component, which can move back and forth, and the symmetrically arranged flattening rollers are used to squeeze and straighten the cable, which effectively reduces the bending arc of the cable caused by coiling, avoids excessive local stress on the cable during laying, prevents conductor deformation and insulation damage, and improves the laying quality and electrical performance of the cable.

[0013] 2. The adjustable limit post group can perform lateral limit and secondary flattening of the cable, which can adapt to different specifications of cables. The flattening roller on the top has a certain buffering capacity under the action of the tension spring, which can ensure the straightening effect and avoid excessive clamping that could lead to poor cable feeding or cable damage.

[0014] 3. By setting a cleaning roller with a damping ring on the reciprocating block, the dust in the thread groove of the reciprocating screw can be automatically cleaned when the reciprocating block moves, preventing dust accumulation from causing the functional block to jam, ensuring smooth reciprocating movement, and improving the stability of cable delivery and the reliability of device operation during the cable feeding process.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a wire laying device for wire and cable construction, including a flattening component and a base 10. Two positioning auxiliary frames 11 are provided on the top of the base 10. Two support frames 12 are fixedly connected to the top of the base 10. Each of the two support frames 12 has a mounting plate 13 inside. A wire laying roller 14 connected by bolts is provided between the two mounting plates 13. Two support rods 15 are fixedly connected to the top of the base 10. Two fixing columns 16 are fixedly connected between the two support rods 15. Reciprocating blocks 17 are slidably connected to the outside of the two fixing columns 16. A flattening component 18 is provided inside the reciprocating block 17. A lateral limiting component 19 is provided outside the reciprocating block 17.

[0019] The right mounting plate 13 is driven by a drive motor to rotate, raising the wire feeding roller 14 to the same center as the mounting plate 13 via the inclined surface of the positioning auxiliary frame 11. Then, the wire feeding roller 14 is rotated until its internal threaded hole corresponds to the internal threaded hole of the mounting plate 13. The installation is carried out under the action of bolts, thus completing the installation of the wire feeding roller 14.

[0020] Furthermore, the flattening assembly 18 includes a rotary motor 181 fixedly connected to the right side of the right support rod 15. A reciprocating screw 182 is fixedly connected to the output end of the rotary motor 181. A functional block 183 is rotatably connected inside the reciprocating block 17. A fixed frame 184 is fixedly connected to the top of the reciprocating block 17. A lifting screw 185 is threadedly connected inside the fixed frame 184. A lifting frame 186 is rotatably connected to the bottom end of the lifting screw 185. A U-shaped mounting plate 187 is slidably connected up and down inside the lifting frame 186. The top of the U-shaped mounting plate 187 is connected to the lifting frame 186. Two tension springs 188 are provided between them. Seven flattening rollers 189 are rotatably connected inside the U-shaped mounting plate 187 and the fixed frame 184. The flattening rollers 189 inside the U-shaped mounting plate 187 and the fixed frame 184 are arranged symmetrically from top to bottom. The two ends of the tension springs 188 are fixed to the U-shaped mounting plate 187 and the lifting frame 186. The lifting frame 186 is slidably connected to the inside of the fixed frame 184. The reciprocating screw 182 passes through the reciprocating block 17 and does not contact the reciprocating block 17. The functional block 183 is movably connected in the threaded groove of the reciprocating screw 182.

[0021] The reciprocating block 17 can only move left and right under the limiting action of the two fixed columns 16. When the reciprocating screw 182 rotates and the functional block 183 moves inside the thread groove, the reciprocating block 17 moves back and forth under the action of the functional block 183. The tension spring 188 causes a set of flattening rollers 189 above to press against the top of the cable, thereby squeezing and straightening the cable.

[0022] Preferably, the lateral limiting component 19 includes two rectangular plates 191 fixedly connected to the front and rear of the reciprocating block 17, and the number of rectangular plates 191 is four. The other two rectangular plates 191 are fixedly connected to the front and rear of the fixed frame 184. The upper two rectangular plates 191 have adjustment grooves 192 inside. Limiting posts 193 are slidably connected to the inside of the adjustment grooves 192. The diameter of the top of the limiting post 193 is larger than the diameter of the adjustment groove 192. Positioning grooves are opened at the corresponding positions of the top of the upper rectangular plates 191 and the top of the limiting posts 193, and the limiting posts 193 are inserted into the positioning grooves. The bottom end of the limiting post 193 passes through the adjustment groove 192 and is inserted into the lower rectangular plate 191.

[0023] It should be noted that the two limiting posts 193 are symmetrically adjusted so that the cable passes straight through the two sets of limiting posts 193, flattening the cable laterally and further straightening it. The diameter of the top of the limiting post 193 is larger than the diameter of the adjusting groove 192, so that after the bottom of the limiting post 193 is inserted into the lower rectangular plate 191, the position of the limiting post 193 is fixed and cannot be adjusted.

[0024] In use, the cable outside the pay-off roller 14 is passed through the two limiting posts 193 and the two sets of flattening rollers 189, and then exits from the two limiting posts 193 at the front end. Then, the lifting screw 185 is rotated to lower the lifting frame 186, causing the U-shaped mounting plate 187 to lower the flattening rollers 189. This presses the cable between the two sets of flattening rollers 189, allowing them to squeeze the cable. The squeezing action of the two sets of flattening rollers 189 effectively reduces the cable's curvature, straightening any bends caused by the cable being wrapped around the pay-off roller 14. The lifting screw 185 can accommodate different specifications... The cable is compressed and flattened, making it more widely applicable. Simultaneously, the U-shaped mounting plate 187, under the action of two tension springs 188 at the top, can move up and down a small distance. This allows the two sets of flattening rollers 189 to flatten the cable without damaging it, and also avoids the problem of inconvenient cable release caused by excessive clamping. After adjusting the two sets of flattening rollers 189, pull the limiting post 193 upwards to disengage its bottom from the rectangular plate 191, then slide the limiting post 193 left and right until its top aligns with the appropriate positioning groove. Finally, press the limiting post 193 down to re-insert its bottom into the lower rectangular plate 191. Similarly, after adjusting the position, the remaining limiting posts 193 can be adjusted to allow the four limiting posts 193 to laterally limit the cable, further flattening it and facilitating cable release. After the cable is tightened and adjusted, the rotary motor 181 is activated during cable release, causing the reciprocating screw 182 to rotate. Since the functional block 183 moves inside the threaded groove of the reciprocating screw 182, the reciprocating block 17 slides left and right outside the two functional blocks 183, thereby driving the fixed frame 184 to reciprocate left and right. The fixed frame 184 moves with the cable on the cable release roller 14. The external position is moved accordingly, so that the cable is pulled out in a straight line between the two sets of flattening rollers 189 after being pulled out by the wire feeding roller 14. This avoids the large angle between the fixed frame 184 and the direction in which the cable is pulled out by the wire feeding roller 14, which makes it susceptible to lateral pulling or torsion. This can lead to excessive local stress on the cable, which may cause conductor deformation, insulation wear or sheath scratches. This not only affects the electrical performance and mechanical strength of the cable, but may also shorten its service life or even cause operational failures. The reciprocating block 17 can move left and right, which further ensures the straight transport of the cable and avoids the inconvenience of subsequent use caused by bending.

[0025] Example 2 Reference Figure 3 , Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides auxiliary components, including damping rings 20 fixedly connected to the inside of the left and right sides of the reciprocating block 17. Rectangular inserts 21 are inserted into the inside of both damping rings 20. A cleaning roller 22 is fixedly connected to the end of the rectangular insert 21 away from the reciprocating block 17. The cleaning roller 22 is in contact with the reciprocating screw 182. Anti-collision grooves are opened on the inner side of the support rod 15 at the corresponding positions of the cleaning roller 22.

[0026] Preferably, the anti-collision groove design inside the support rod 15 ensures that when the reciprocating block 17 contacts the support rod 15, the cleaning roller 22 is inserted into the anti-collision groove, preventing damage to the cleaning roller 22. When the cleaning roller 22 is worn out and needs to be replaced, the cleaning roller 22 is pulled out of the damping ring 20, and then the new cleaning roller 22 is inserted into the damping ring 20 through the rectangular insert 21, realizing quick installation and removal of the cleaning roller 22.

[0027] In use, the cleaning roller 22 is positioned to act as a reciprocating block 17. When the reciprocating block 17 moves, it drives the cleaning roller 22 to move as well. Since the external bristles of the cleaning roller 22 are in contact with the reciprocating screw 182, the cleaning roller 22 cleans the rotating reciprocating screw 182 when it rotates, thereby removing dust from the thread groove of the reciprocating screw 182. This makes the function block 183 move more smoothly inside the thread groove of the reciprocating screw 182, avoiding the problem of large amounts of dust clogging the thread groove of the reciprocating screw 182 and causing the function block 183 to move inconveniently when used in the construction site. This makes the movement of the reciprocating block 17 smoother, thus making cable laying more convenient.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
