Description

Technical Field

[0001] This utility model relates to the field of cable laying tools, and in particular to a cable threading device. Background Technology

[0002] Cable pulling devices are tools used to assist in cable pulling during cable laying, typically referring to cable pullers (cable winches). They are designed to improve pulling efficiency, reduce cable damage, and ensure construction safety. When using a cable puller, the cable is wound around the puller, and the pulling mechanism is operated to provide sufficient tension, allowing the cable to smoothly pass through obstacles along the guide mechanism. During the pulling process, fixing and clamping devices maintain the stability of the cable, preventing it from falling off or being damaged.

[0003] When using existing cable pullers, the cable does not receive effective guidance and support during the pulling process. The cable is prone to friction and damage due to friction with the structure of the cable puller, and it does not receive effective protection. Furthermore, during the pulling process, the cable can move forward and backward, which will affect the normal pulling and pulling process. To avoid damage caused by cable retraction and ensure the integrity of the cable, it is necessary to prevent the cable from being damaged. Utility Model Content

[0004] The main objective of this invention is to provide a cable threading device that can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable threading device includes a base frame, a fixed seat fixed on the base frame, a rotating shaft provided on the fixed seat, a fixed ring installed on the rotating shaft, a support frame fixed on the fixed seat, and a guide check structure provided on the support frame.

[0007] Preferably, one end of the base frame is provided with a wheel, and the other end of the base frame is fixed with a support block. The rotating shaft is provided with a support rod, and the fixing ring is provided on the support rod.

[0008] Preferably, the fixed base is provided with a bearing, the rotating shaft is rotatably mounted on the fixed base through the bearing, and the end of the rotating shaft is provided with a manual wheel.

[0009] Preferably, the guide check structure includes a guide sleeve, a mounting sleeve, a movable hole, a through hole, an arc-shaped groove, a connecting spring, an arc-shaped check piece, and a control component. The guide sleeve is fixedly connected to the mounting sleeve, and the mounting sleeve is mounted on the support frame through the movable hole. The through hole is formed on the guide sleeve, and the arc-shaped groove is disposed in the through hole on the guide sleeve. The connecting spring and the arc-shaped check piece are fixedly connected, and the end of the connecting spring is fixed in the through hole on the guide sleeve. The end of the arc-shaped check piece is disposed in the arc-shaped groove, and the control component is mounted on the guide sleeve.

[0010] Preferably, the control component includes a waist-shaped hole, a control ring, a groove, a connecting post, a stud, and a locking block.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-3As shown, a cable threading device includes a base frame 1, a fixed seat 2 fixed on the base frame 1, a rotating shaft 3 on the fixed seat 2, a fixing ring 4 mounted on the rotating shaft 3, a support frame 5 fixed on the fixed seat 2, and a guide check structure 6 on the support frame 5. One end of the base frame 1 is equipped with a wheel 7, and the other end is fixed with a support block 8. The wheel 7 and the support block 8 work together to allow for rapid movement of the device, while the support block 8 ensures the stability of the device after placement. A support rod is mounted on the rotating shaft 3, and the fixing ring 4 is mounted on the support rod. A bearing is provided on the fixed seat 2, and the rotating shaft 3 is rotatably mounted on the fixed seat 2 via the bearing. A manual wheel 9 is provided at the end of the rotating shaft 3, allowing for cable feeding operations, making the threading process more convenient.

[0018] When using the cable threading device, the wheel 7 on the base frame 1 is used to move it to a suitable location, where it is stably placed by the support block 8. The cable end on the rotating shaft 3 is passed through the guide check structure 6 on the support frame 5, and the cable is moved by the traction structure to perform the threading operation. During the threading process, the rotating shaft 3, along with the fixing ring 4 and the cable, rotates on the fixed seat 2 to release the cable. The guide check structure 6 guides and supports the cable, effectively protecting it. The guide check structure 6 can also move along the support frame 5 without affecting the normal cable threading operation. When needed, the rotating shaft 3 can be rotated by the manual wheel 9 for manual cable release, improving threading efficiency.

[0019] According to the above implementation scheme, the guide check structure 6 includes a guide sleeve 601, a mounting sleeve 602, a movable hole 603, a through hole 604, an arc-shaped groove 605, a connecting spring 606, an arc-shaped check piece 607, and a control component 608. The guide sleeve 601 is fixedly connected to the mounting sleeve 602, and the mounting sleeve 602 is mounted on the support frame 5 through the movable hole 603. The through hole 604 is opened on the guide sleeve 601. The arc-shaped groove 605 is set in the through hole 604 on the guide sleeve 601. The connecting spring 606 and the arc-shaped check piece 607 are fixedly connected, and the end of the connecting spring 606 is fixed in the through hole 604 on the guide sleeve 601. The end of the arc-shaped check piece 607 is set in the arc-shaped groove 605. The control component 608 is mounted on the guide sleeve 601.

[0020] When using the guide check structure 6, the cable moves through the through hole 604 on the guide sleeve 601. During the cable threading process, the connection between the connecting spring 606 and the arc-shaped check piece 607 is compressed, causing the connecting spring 606 to deform. The arc-shaped check piece 607 moves and makes room in the arc-shaped groove 605, without affecting the normal forward movement of the cable. When the cable retracts, the cable is blocked by the combined action of the arc-shaped check piece 607 and the connecting spring 606, which can prevent the cable from retracting.

[0021] During the cable threading process, the mounting sleeve 602 can move and rotate through the movable hole 603, so that the guide sleeve 601 can better adapt to the direction of the cable, which is highly flexible. When needed, the control component 608 can compress the connecting spring 606 to make room, at which time the cable can be moved back, which makes it easy to retract and recycle excess cable.

[0022] The control assembly 608 includes a slotted hole 6081, a control ring 6082, a groove 6083, a connecting post 6084, a stud 6085, and a locking block 6086. The slotted hole 6081 is formed on the guide sleeve 601 and is connected to the through hole 604. The groove 6083 is formed on the control ring 6082 and the control ring 6082 is disposed in the through hole 604 on the guide sleeve 601. The connecting post 6084 and the stud 6085 are fixedly connected, and the connecting post 6084 is mounted on the control ring 6082 and is located inside the slotted hole 6081. The locking block 6086 is threadedly connected to the stud 6085.

[0023] When using the control component 608, the locking block 6086 on the stud 6085 is rotated to allow for repositioning. Then, force is applied through the locking block 6086, causing the connecting post 6084 to move in the oblong hole 6081, thereby moving the control ring 6082 within the through hole 604. The control ring 6082 applies force to the connecting spring 606 through the groove 6083, causing the connecting spring 606 to deform. The arc-shaped check piece 607 then enters the arc-shaped groove 605 to allow for repositioning. Rotating the locking block 6086 fixes the position of the control ring 6082, after which the cable can be retracted. When the cable needs to move forward normally, rotating the locking block 6086 allows for repositioning. After the control ring 6082 repositions, the connecting spring 606 and the arc-shaped check piece 607 reset and continue to function as a check valve.

[0024] It should be noted that the guide check structure 6 effectively supports and guides the cable during the threading process, preventing the cable from contacting other structures in the threader and causing wear, thus ensuring the cable's integrity. A connecting spring 606 and an arc-shaped check piece 607 are installed in the through hole 604 on the guide sleeve 601. When the cable moves forward, the connecting spring 606 undergoes elastic deformation, and the arc-shaped check piece 607 moves into the arc-shaped groove 605, without affecting the normal threading of the cable. When the cable retracts, the arc-shaped check piece 607 acts as a backstop, preventing the cable from retracting and affecting the normal progress of the laying work. The control component 608, using the control ring 6082, allows the connecting spring 606 to undergo elastic deformation and reposition, enabling manual control of cable retraction, offering high flexibility and adaptability.
