Description

Technical Field

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

[0002] During weak current construction, cable laying 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 winding reels are prone to jamming, deflection, or even tipping over during the unwinding process due to unstable placement or inadequate fixation, 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 likely to become entangled with each other, thereby affecting the neatness of the cable arrangement and the threading accuracy to a certain extent. At the same time, when more cables are released from the 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 winding reels that may become stuck, skewed or even tip over due to unstable placement or improper fixation during use, and that are more prone to entanglement due to limited cable guidance distribution methods, thereby affecting the threading accuracy and operation stability, 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 cable guidance, 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.

[0006] In one embodiment, the gathering mechanism includes a fixed clamping roller, a fixed clamping roller is rotatably provided in the middle of the frame, a double-rod hydraulic cylinder is installed on the upper and lower sides of the frame, two sliders 1 and two sliders 2 are slidingly provided on the upper and lower sides of the frame respectively, the two sliders 1 on the same side of each group are arranged between the two sliders 2, a rotatable movable clamping rod 1 is provided between the two sliders 1 located at different horizontal planes, and a rotatable movable clamping rod 2 is provided between the two sliders 2 located at different horizontal planes, a return spring is connected between the sliders 1 and 2 on the same side of each group, and a connecting plate is installed on the side away from each other of the four sliders 2, the two telescopic rods of the upper double-rod hydraulic cylinder are respectively connected to the two connecting plates on the upper side, and the two telescopic rods of the lower double-rod hydraulic cylinder are respectively connected to the two connecting plates on the lower side.

[0007] In one embodiment, the guide mechanism includes an inclined frame, which is installed on the side of the frame close to the transverse roller. A movable block is slidably installed on the inclined frame, and the movable block is connected to a knob by a threaded connection. A movable frame is provided on the movable block, and a rotatable guide frame is provided on the movable frame. A torsion spring is connected between the guide frame and the movable frame.

[0008] In one embodiment, a correction mechanism is also included, which includes a sliding rod. Two symmetrically arranged sliding rods are slidably provided on the frame. The two sliding rods slide through three of the trays. Four downward pressure frames are fixedly installed at even intervals between the two sliding rods. Three of the downward pressure frames are located at the bottom of the three trays passed by the sliding rods. The four downward pressure frames are respectively located on the upper part of the four horizontal plates. A pedal is installed at the lower part of each of the two sliding rods, and a magnet block is installed on both sides of the frame.

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

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

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

[0012] In one embodiment, it further includes a magnet ring 1 and a magnet ring 2. A magnet ring 1 is installed on each side of the four clamping blocks that are close to each other, and four magnet rings 2 are evenly spaced and installed on each tray.

[0013] In one embodiment, the magnetic poles of the magnet ring 1 and the magnet ring 2 on opposite sides of each set of magnet rings close to each other are opposite, and the magnet ring 1 and the magnet ring 2 are attracted to each other.

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

[0015] The present invention has the following advantages: 1. It helps to realize the centralized guidance of multiple cables and improves the threading adaptability:

[0016] By controlling the two telescopic rods on each double-rod hydraulic cylinder to shrink towards each other, the four connecting plates, four sliders 1, four sliders 2, two movable clamping rods 1 and two movable clamping rods 2 can be driven to move closer to the middle, so that the four rows of cable heads can be arranged relatively concentratedly; on this basis, through the coordinated guidance of the cross roller and the guide frame, the sixteen cables can obtain relatively independent guide channels respectively, thereby reducing the entanglement between the cables to a certain extent; during the threading process, the guide frame can produce a certain swing under the action of the torsion spring, and has a certain adaptive ability, which is convenient for adaptation and adjustment according to the direction of the threading holes at different construction locations, thereby improving the smoothness of the threading operation and on-site adaptability to a certain extent.

[0017] 2. Facilitate the rapid compression and synchronous correction of the winding drum, improving the efficiency of the preparation process:

[0018] When two operators step on the two pedals, they drive the two slide bars and four lower pressure frames downward, disengaging the pedals from the two magnets. As the four lower pressure frames move downward synchronously, they apply a vertical downward pressure to the multiple winding reels, forcing them to fit snugly against the bottom of the tray for uniform and stable compression. This rapid compression mechanism assists in correcting the positioning and placement of the winding reels, thereby reducing the risk of jamming or deflection during unwinding caused by improper reel placement, further improving unwinding smoothness and overall threading efficiency.

[0019] 3. Facilitate the realization of multi-point stable pressing and position maintenance of the winding drum:

[0020] Sixteen gears are driven to rotate by four racks, and the sixteen gears can drive sixteen threaded rods to move upward while rotating. The arc structure set on the top of the threaded rod can push four balls, four clamping blocks and four magnet rings in turn to move away from each other, so that the corrected winding drum can obtain clamping support in multiple directions; under the working conditions of reducing the amount of cable in the winding drum and reducing the weight of the winding drum, the four clamping blocks can still play a certain fixing role, thereby reducing the shaking of the winding drum caused by factors such as center of gravity offset and rotational inertia to a certain extent, which helps to improve the overall stability of the winding drum unwinding process and improve the efficiency of threading.

In each column, the four cable heads located on the same horizontal plane are located under the corresponding cross roller 3. Then, the operator controls the two telescopic rods of each double-rod hydraulic cylinder 62 to retract in the direction of approaching each other.

The reset springs 65 are compressed, and the four sliders 1 631 and the four sliders 2 641 drive the two movable When the lever 72 is in the unlocked position, the operator can lock the locking cam 74 by rotating the knob 73 so that the locking cam 74 is locked and the locking cam 74 is in the unlocked position. For the initial guiding of the cable, the operator unlocks the four self-locking universal wheels 2, moves the equipment to the threading position in the construction area, locks the self-locking universal wheels 2, brings the cable heads close to the threading holes, and uses the threading tool to fix the rear ends of the sixteen cable heads, and then starts the threading operation; by controlling the two telescopic rods on each double-rod hydraulic cylinder 62 to retract in the direction of approaching each other, the two telescopic rods on the double-rod hydraulic cylinder 62 drive the four connecting plates 66, four sliders 1 631, four sliders 2 641, two movable clamping rods 1 632 and two movable clamping rods 2 642 to move in the direction of approaching each other, so that the four rows of cable heads can be gathered, and the cables are guided for the second time by the cross roller 3 and the guide frame 75, so that each cable can be Independent guidance avoids cable entanglement and improves threading efficiency; during the threading process, the torsion spring 76 provides rotational elastic force, so that the guide frame 75 has a certain adaptive swing ability, and can automatically adjust its posture according to different construction angles, thereby adapting to threading holes in various directions, effectively improving construction adaptability and threading smoothness; after the threading operation is completed, the operator removes the empty winding reel and controls the telescopic rods of the double-rod hydraulic cylinder 62 to extend in the direction away from each other, so that the connecting plate 66, slider 1 631, slider 2 641 and reset spring 65 gradually return to their positions; under the elastic force of the reset spring 65, the movable clamping rod 1 632 and the movable clamping rod 2 642 separate to both sides and return to the initial spacing state, preparing for the next round of threading operation.

[0041] The pedals 83 are made of iron material, and the two pedals 83 are respectively adsorbed on the corresponding magnet blocks 84.

[0042] The two operators step on the pedals 83 on both sides respectively, so that the pedals 83 drive the slide bar 81 and the lower pressure frame 82 to move downward synchronously. After the pedals 83 disengage from the magnet block 84, the four lower pressure frames 82 perform a vertical pressing operation on the winding reels so that all the winding reels are in contact with the bottom of the tray 5; after the correction is completed, the operator pushes the pedals 83 up to restore the slide bar 81 and the lower pressure frame 82 to their original positions, and the pedals 83 are again adsorbed by the magnet block 84, and the slide bar 81 and the lower pressure frame 82 are stably fixed to ensure the stability of subsequent operations.
