Description

Technical Field

[0001] The invention relates to the field of cable threading, and in particular to a weak current construction threading auxiliary device. Background Art

[0002] During the weak current construction process, the laying of cables often involves a large number of cable wires, which usually need to be sorted and unwound on a winding drum before threading.

[0003] However, in actual use, traditional cable winding reels are prone to jamming, deflection, or even tipping over during the unwinding process due to unstable placement, inadequate fixation, and other factors, affecting the smoothness and efficiency of subsequent threading operations. In addition, since multiple cables often need to be introduced into the threading holes at the same time, if the guiding method does not have a good distribution structure, the cables are prone to become entangled with each other, which to a certain extent affects the neatness of the cable arrangement and the threading accuracy. At the same time, when more cables are released from the cable winding reel and the overall mass is reduced, it is more likely to shake or deviate, which in turn affects the smoothness of unwinding and the stability of continuous operation. Summary of the invention

[0004] In order to overcome the shortcomings of traditional cable winding reels that may become stuck, skewed or even tip over due to unstable placement or improper fixation during use, and the limited cable guidance distribution method, which makes it easier for entanglement to occur, thereby affecting the threading accuracy and operation stability to a certain extent, it is necessary to provide a weak current construction threading auxiliary equipment. Through a relatively stable placement and fixed structure, it helps to improve the smoothness and stability of the unwinding process. Combined with guiding the cable, it can slow down the entanglement phenomenon to a certain extent, improve the cable arrangement effect, and help improve the threading accuracy and the continuous stability of the operation process.

[0005] The technical solution of the present invention is: a weak current construction threading auxiliary equipment, including a frame, four self-locking universal wheels are arranged at the bottom of the frame, a plurality of transverse rollers are rotatably arranged at even intervals on one side of the frame, a plurality of transverse plates are fixedly installed at even intervals on the other side of the frame, a plurality of trays are rotatably arranged at even intervals on each transverse plate, a gathering mechanism is arranged on the frame, and a guiding mechanism is arranged on the frame.

[0006] In one embodiment, the gathering mechanism includes a fixed pinch roller. A fixed pinch roller is rotatably provided in the middle of the frame body. A double-rod hydraulic cylinder is installed on both the upper and lower sides outside the frame body. Two slider ones and two slider twos are respectively slidably provided on the upper and lower sides of the frame body. The two slider ones of each same side are arranged between the two slider twos. A rotatable movable pinch roller one is provided between the two slider ones located on different horizontal planes. A rotatable movable pinch roller two is provided between the two slider twos located on different horizontal planes. A return spring is connected between the slider one and the slider two of each same side. A connecting plate is installed on the side where the four slider twos are away from each other. The two telescopic rods of the upper double-rod hydraulic cylinder are respectively connected to the opposite sides of the upper two connecting plates. The two telescopic rods of the lower double-rod hydraulic cylinder are respectively connected to the opposite sides of the lower two connecting plates.

[0007] In one embodiment, the guiding mechanism includes an inclined frame. An inclined frame is installed on the side of the frame body close to the cross roller. A movable block is slidably installed on the inclined frame. The movable block is connected with a knob in a threaded connection manner. An activity frame is provided on the movable block. A rotatable guiding frame is provided on the activity frame. A torsion spring is connected between the guiding frame and the activity frame.

[0008] In one embodiment, a correction mechanism is further included. The correction mechanism includes sliding rods. Two symmetrically arranged sliding rods are slidably provided on the frame body. The two sliding rods both slidably pass through three of the trays. Four pressing frames are evenly and spacedly fixedly installed between the two sliding rods. Three of the four pressing frames are located at the inner bottoms of the three trays through which the sliding rods pass. The four pressing frames are respectively located above the four cross plates. A pedal is installed at the lower part of each of the two sliding rods. A magnet block is installed on both sides of the frame body.

[0009] In one embodiment, the pedals are made of iron material, and the two pedals are respectively adsorbed on the corresponding magnet blocks.

[0010] In one embodiment, a clamping mechanism is further included. The clamping mechanism includes clamping blocks. Four clamping blocks are slidably provided on each tray. A ball is rollingly embedded at one end where the four clamping blocks are close to each other. A threaded rod is connected to the lower part of each tray in a threaded connection manner. The top of the threaded rod is arc-shaped. The arc at the top of the threaded rod contacts the four balls. A gear is installed at the bottom of the threaded rod. A rack is slidably provided on each cross plate. The racks on each cross plate are meshed with the four gears in the corresponding cross plates. A vertical frame is connected between two of the connecting plates. The vertical frame is fixedly connected with the four racks.

[0011] In one embodiment, the width of the rack is greater than the thickness of the gear meshed with it.

[0012] In one embodiment, it further includes a first magnet ring and a second magnet ring. A first magnet ring is installed on one side of each of the four clamping blocks close to each other, and four second magnet rings are evenly and spacedly installed on each tray.

[0013] In one embodiment, the opposite sides of the first magnet ring and the second magnet ring in each group close to each other have opposite magnetic poles, and the first magnet ring and the second magnet ring adsorb to each other.

[0014] In one embodiment, it further includes guide rollers. Two rotatable guide rollers are provided on the guide frame.

[0015] The present invention has the following advantages: 1. It helps to achieve the centralized guiding of multiple cables and improve the threading adaptability: By controlling the two telescopic rods on each double-rod hydraulic cylinder to contract towards each other, it can drive the four connecting plates, the four first sliders, the four second sliders, the two first movable clamping rods and the two second movable clamping rods to move closer to the middle, so as to make the four rows of cable heads achieve a relatively centralized arrangement; on this basis, through the cooperation and guidance of the cross roller and the guide frame, the sixteen cables can respectively obtain relatively independent guiding channels, thereby reducing the winding situation between the cables to a certain extent; during the threading process, the guide frame can swing to a certain extent under the action of the torsion spring, with a certain self-adaptive ability, which is convenient for adapting and adjusting according to the threading hole direction at different construction positions, thereby improving the smoothness of the threading operation and the on-site adaptability to a certain extent.

[0016] 2. It is convenient for quickly pressing and synchronously correcting the wire reels, improving the efficiency of the preparation process: After two operators step on the pedals on both sides respectively, the two pedals drive the two sliding rods and the four pressing frames to move downward, so that the pedals are separated from the two magnet blocks; as the four pressing frames move downward synchronously, a vertically downward pressing force can be applied to multiple wire reels, so that all the wire reels are attached to the bottom of the tray, which is convenient for achieving unified pressing and stabilization. The quick pressing operation through this structure can assist in the correction of the positioning and placement of the wire reels, thereby reducing the jamming or skewing problems caused by improper placement of the wire reels during the unwinding process to a certain extent, further improving the smoothness of the unwinding and enhancing the overall threading efficiency.

[0017] 3. It is convenient for achieving multi-point stable pressing and position maintaining of the wire reels: Four racks drive sixteen gears to rotate. The sixteen gears can drive sixteen threaded rods to move upward while rotating. The arc structures provided at the tops of the threaded rods can sequentially push four balls, four clamping blocks, and four magnet rings II to move away from each other; enabling the corrected wire winding disc to obtain clamping support in multiple directions; under the condition that the amount of cable in the wire winding disc decreases and the self-weight of the wire winding disc decreases, the four clamping blocks can still play a certain fixing role, thereby reducing to a certain extent the wobbling phenomenon of the wire winding disc caused by factors such as center of gravity offset and rotational inertia, and helping to improve the overall stability of the wire unwinding process of the wire winding disc and the efficiency of threading.

Specific embodiments

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention and do not specifically limit the present invention.

[0033] Embodiment 1: A weak current construction wire threading auxiliary device, as Figures 1 - 7 shown, includes a frame body 1. Four self-locking universal wheels 2 are provided at the bottom of the frame body 1. Four horizontal rollers 3 are rotatably provided on one side of the frame body 1 at equal intervals through bearings. Four horizontal plates 4 are fixedly installed on the other side of the frame body 1 at equal intervals. Four trays 5 are rotatably provided on each horizontal plate 4 at equal intervals. The trays 5 are used for placing cable reels. A gathering mechanism is provided on the frame body 1, and the gathering mechanism is used for initially gathering the cables. A guiding mechanism is provided on the frame body 1, and the guiding mechanism is used for secondarily gathering the initially gathered cables and can adjust the turning position of the cables to adapt to construction sites of different heights.

[0034] The gathering mechanism includes a fixed pinch roller 61. A fixed pinch roller 61 is rotatably arranged in the middle of the frame body 1. A double-rod hydraulic cylinder 62 is installed on both the upper and lower sides outside the frame body 1. Two slider ones 631 and two slider twos 641 are respectively slidably arranged on the upper and lower sides of the frame body 1. The two slider ones 631 on the same side of each group are arranged between the two slider twos 641. A rotatable movable pinch rod one 632 is arranged between the two slider ones 631 at different horizontal levels. A rotatable movable pinch rod two 642 is arranged between the two slider twos 641 at different horizontal levels. A return spring 65 is connected between the slider one 631 and the slider two 641 on the same side of each group. A connecting plate 66 is installed on the side where the four slider twos 641 are away from each other. The two telescopic rods of the upper double-rod hydraulic cylinder 62 are respectively connected to the opposite sides of the two upper connecting plates 66. The two telescopic rods of the lower double-rod hydraulic cylinder 62 are respectively connected to the opposite sides of the two lower connecting plates 66.

[0035] The guiding mechanism includes an inclined frame 71. An inclined frame 71 is installed on the side of the frame body 1 close to the cross roller 3. A movable block 72 is slidably installed on the inclined frame 71. The movable block 72 is connected with a knob 73 by a threaded connection method. An activity frame 74 is arranged on the movable block 72. A rotatable guiding frame 75 is arranged on the activity frame 74. The guiding frame 75 is used for secondary gathering of the cable. A torsion spring 76 is connected between the guiding frame 75 and the activity frame 74.

[0036] The operator first places the cable reels full of cables on the trays 5 respectively, and then pulls out the cable heads on the cable reels, so that four cable heads in each column are respectively located between two movable pinch rollers 632, or between the fixed pinch roller 61 and the movable pinch roller 632, forming a total of four columns of cable heads. In each column, the four cable heads located on the same horizontal plane are located below the corresponding cross rollers 3. Subsequently, the operator controls the two telescopic rods of each double-rod hydraulic cylinder 62 to contract in the direction of approaching each other. The two telescopic rods of the double-rod hydraulic cylinder 62 drive the four connecting plates 66, the four first sliders 631, the four second sliders 641 and the four return springs 65 to move towards the center. The return springs 65 are compressed. The four first sliders 631 and the four second sliders 641 drive the two movable pinch rollers 632 and the two movable pinch rollers 642 to move towards the middle synchronously, realizing the preliminary gathering of the four columns of cable heads. Then, the operator rotates the knob 73 to move it in the direction away from the inclined frame 71. After the knob 73 is separated from the inclined frame 71, the movable frame 74 is moved up or down, driving the movable block 72, the knob 73, the guide frame 75 and the torsion spring 76 to slide synchronously. According to the height requirements of the construction site, after adjusting the guide frame 75 to an appropriate position, the operator reversely tightens the knob 73 to make the knob 73 fit with the inclined frame 71 again, realizing the locking of the positions of the movable block 72, the movable frame 74, the guide frame 75 and the torsion spring 76. Subsequently, the sixteen cable heads are sequentially passed through the guide frame 75. At this time, the four cross rollers 3 play a preliminary guiding role for the cables. The operator unlocks the four self-locking universal wheels 2, moves the equipment to the threading position in the construction area and then locks the self-locking universal wheels 2, makes the cable heads close to the threading hole, and fixes the rear ends of the sixteen cable heads by using a threading tool, and then the threading operation can be started. By controlling the two telescopic rods on each double-rod hydraulic cylinder 62 to contract in the direction of approaching each other, the two telescopic rods on the double-rod hydraulic cylinder 62 drive the four connecting plates 66, the four first sliders 631, the four second sliders 641, the two movable pinch rollers 632 and the two movable pinch rollers 642 to move in the direction of approaching each other, so that the four columns of cable heads can be gathered. The cables are secondarily guided by the cross rollers 3 and the guide frame 75, so that each cable obtains independent guidance, avoiding cable entanglement and improving the threading efficiency. During the threading process, the torsion spring 76 provides a rotational elastic force, enabling the guide frame 75 to have a certain self-adaptive swinging ability, and it can automatically adjust its posture according to different construction angles, so as to adapt to the threading holes in various directions, effectively improving the construction adaptability and the threading smoothness. After the threading operation is completed, the operator removes the empty cable reel, and at the same time controls the telescopic rods of the double-rod hydraulic cylinder 62 to extend in the direction of moving away from each other, so that the connecting plates 66, the first sliders 631, the second sliders 641 and the return springs 65 gradually return to their original positions. Under the elastic force of the return springs 65, the movable pinch rollers 632 and the movable pinch rollers 642 separate from each other and return to the initial spacing state, preparing for the next round of threading operation.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figures 8 - 10 shown, it further includes a correction mechanism arranged on the frame body 1 and the cross plate 4. The correction mechanism is used to synchronously correct a plurality of winding discs. The correction mechanism includes a slide bar 81. Two symmetrically arranged slide bars 81 are slidably arranged on the frame body 1. Both slide bars 81 slidably pass through three of the pallets 5. Four pressing frames 82 are fixedly installed at equal intervals between the two slide bars 81. Three of the pressing frames 82 are located at the inner bottom of the three pallets 5 through which the slide bars 81 pass. The four pressing frames 82 are respectively located above the four cross plates 4. A pedal 83 is installed at the lower part of each of the two slide bars 81. A magnet block 84 is installed on both sides of the frame body 1.

[0038] The pedal 83 is made of iron material, and the two pedals 83 are respectively adsorbed on the corresponding magnet blocks 84.

[0039] Two operators step on the pedals 83 on both sides respectively, so that the pedals 83 drive the slide bars 81 and the pressing frames 82 to move downward synchronously. After the pedals 83 are separated from the magnet blocks 84, the four pressing frames 82 perform a vertical pressing operation on the winding discs, so that all the winding discs are attached to the bottom of the pallets 5. After the correction is completed, the operator pulls up the pedals 83 to restore the slide bars 81 and the pressing frames 82 to their original positions. The pedals 83 are adsorbed by the magnet blocks 84 again, and the slide bars 81 and the pressing frames 82 are stably fixed, ensuring the smoothness of subsequent operations. The two slide bars 81 and the four pressing frames 82 are all made of lighter materials, which is convenient for rapid operation. By synchronously correcting the winding discs, the problems caused by the skew or jamming of the winding discs during the unwinding process are effectively avoided, thereby improving the smoothness of the unwinding of the winding discs and significantly improving the threading efficiency at the same time.

[0040] Embodiment 3: On the basis of Embodiment 2, as Figures 8 - 13 shown, it further includes a clamping mechanism arranged on the cross plate 4, the pallet 5 and the connecting plate 66. The clamping mechanism is used to clamp the winding discs. The clamping mechanism includes a clamping block 91. Four clamping blocks 91 are slidably arranged on each pallet 5. A ball 92 is rollingly embedded at one end of the four clamping blocks 91 close to each other. A threaded rod 95 is connected to the lower part of each pallet 5 by a threaded connection. The top of the threaded rod 95 is arc-shaped. The arc at the top of the threaded rod 95 contacts the four balls 92. A gear 96 is installed at the bottom of the threaded rod 95. A rack 97 is slidably arranged on each cross plate 4. The rack 97 on each cross plate 4 meshes with the four gears 96 in the corresponding cross plate 4. A vertical frame 98 is connected between two of the connecting plates 66. The vertical frame 98 is fixedly connected to the four racks 97.

[0041] The width of the rack 97 is greater than the thickness of the gear 96 meshing with it.

[0042] It also includes a first magnet ring 10 and a second magnet ring 11. A first magnet ring 10 is installed on one side of each of the four clamping blocks 91 that are close to each other, and four second magnet rings 11 are evenly and spacedly installed on each tray 5.

[0043] The opposite sides of the first magnet ring 10 and the second magnet ring 11 that are close to each other in each group have opposite magnetic poles, and the first magnet ring 10 and the second magnet ring 11 attract each other.

[0044] It also includes guide rollers 12. Two rotatable guide rollers 12 are provided on the guide frame 75.

[0045] After all the winding discs are corrected, the two telescopic rods of the double-rod hydraulic cylinder 62 contract synchronously in the direction of approaching each other, successively driving the four connecting plates 66, the four first sliders 631, the four second sliders 641, the two first movable clamping rods 632 and the two second movable clamping rods 642 to move towards the center, effectively gathering the four rows of cable heads; during the gathering process, two of the connecting plates 66 further drive the vertical frame 98 and the four racks 97 to move in the same direction. The four racks 97 engage with the sixteen gears 96 and drive them to rotate, thereby driving the sixteen threaded rods 95 to move upward while rotating; during this process, the gears 96 always remain engaged with the racks 97. The arc structure at the top of the threaded rod 95 pushes the four balls 92, the four clamping blocks 91 and the four second magnet rings 11 to move in the direction of moving away from each other, and finally the clamping blocks 91 fix the corrected winding discs; after the threading operation is completed, two of the connecting plates 66 drive the vertical frame 98 and the four racks 97 to move in the reverse direction. The four racks 97 drive the sixteen gears 96 to rotate in the reverse direction, and further cause the sixteen threaded rods 95 to move downward while rotating; during this process, the gears 96 continue to remain engaged with the racks 97; the arc structure at the top of the threaded rod 95 gradually separates from the four balls 92. Relying on the magnetic adsorption between the four first magnet rings 10 and the second magnet rings 11, the four clamping blocks 91, the four second magnet rings 11 and the four balls 92 move in the direction of approaching each other, realizing the automatic reset of the clamping blocks 91 and releasing the winding discs; at this time, the operator can easily remove the empty winding discs, completing a complete threading cycle; by driving the sixteen gears 96 to rotate through the four racks 97, the sixteen gears 96 drive the sixteen threaded rods 95 to move upward while rotating, and the arc structure at the top of the threaded rod 95 pushes the four balls 92, the four clamping blocks 91 and the four second magnet rings 11 to move in the direction of moving away from each other, thereby realizing the stable fixation of the corrected winding discs; when the amount of cable in the winding disc is small and the overall weight is reduced, with the fixing effect of the clamping blocks 91, it is possible to prevent the winding disc from sliding or shaking due to insufficient self-weight during the unwinding process, ensuring the stability of the unwinding and further improving the threading efficiency.

[0046] During the threading process of the sixteen cables, the guide rollers 12 on the guide frame 75 can effectively guide the cables, thereby improving the smoothness of the threading and the overall construction efficiency.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
