Description

Technical Field

[0001] This utility model relates to the field of power construction technology, and in particular to a power construction traction device. Background Technology

[0002] During power construction, traction devices are often used to pull cables, eliminating the need for manual pulling by workers, reducing their workload, and maintaining a constant force on the cables to avoid straining them.

[0003] However, most existing traction devices use roller-type traction structures, and the force applied to the cable is point contact or line contact, which can easily cause slippage between the cable sheath and the cable, resulting in unsuccessful traction. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a power construction traction device, which effectively solves the problem of slippage between the traction mechanism and the cable, affecting traction.

[0005] The technical solution to the problem is as follows: a power construction traction device, including a housing, with an inlet and an outlet at both ends of the housing, and two traction mechanisms slidably arranged on both sides inside the housing. Each traction mechanism includes a slider that reciprocates inside the housing, with two grippers hinged at one end of the slider in the middle of the housing. A hydraulic cylinder is installed inside the slider, and the telescopic rod of the hydraulic cylinder is connected to the grippers via a connecting rod, forming a structure in which the hydraulic cylinder controls the opening and closing of the two grippers. When the two grippers are closed, they clamp the cable, and the slider slides inside the housing to achieve traction of the cable.

[0006] Preferably, the housing is provided with two lead screws and multiple guide rods, and the slider is provided with threaded holes that are threaded to the lead screws and guide holes that pass through the guide rods.

[0007] Preferably, a motor for driving the lead screw is provided outside the housing.

[0008] This utility model has a simple and ingenious structure and is easy to use. By using sliding claws to pull the cable, the contact area with the cable is increased, ensuring the pulling force on the cable and thus completing the pulling smoothly and ensuring the construction progress.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 5 It is known that a power construction traction device includes a housing 1, with an inlet 2 and an outlet 3 at both ends of the housing 1. Two traction mechanisms are slidably arranged on both sides inside the housing 1. The traction mechanism includes a slider 4 that moves back and forth inside the housing 1. Two grippers 5 are hinged to one end of the slider 4 in the middle of the housing 1. A hydraulic cylinder 6 is arranged inside the slider 4. The telescopic rod of the hydraulic cylinder 6 is connected to the grippers 5 of the connecting rod 7 via a connecting rod 7, forming a structure in which the hydraulic cylinder 6 controls the opening and closing of the two grippers 5. After the two grippers 5 are closed, they clamp the cable. The slider 4 slides inside the housing 1 to achieve traction of the cable.

[0016] In practical use, this utility model Insert the cable into the housing 1 through the inlet 2 and pull it out through the outlet 3. Start the device, and the two traction mechanisms alternately clamp the cable with the claws 5 to move it. Before one claw 5 releases the cable, the other claw 5 clamps the cable first. The two alternately move back and forth to pull the cable.

[0017] In this device, the gripper 5 is made in an arc shape. When the two grippers 5 are closed, they can clamp the cable inside. At this time, the gripper 5 and the cable have a contact surface of the entire arc, so that the gripper 5 and the cable do not slip and the traction force is guaranteed.

[0018] Before the cable is inserted, the jaws 5 on both sides are not closed and are in an open state. After the cable is inserted, the jaws 5 on the side of the cable inlet 2 close to clamp the cable and then begin to pull.

[0019] The housing 1 contains two lead screws 8 and multiple guide rods 9. The slider 4 has threaded holes 10 that are threaded to the lead screws 8 and guide holes 11 that pass through the guide rods 9. The housing 1 is equipped with a motor 12 that drives the lead screws 8. The motor 12 drives the lead screws 8 to drive the slider 4, causing it to reciprocate within the housing 1. The movement of the slider 4 is coordinated with the extension and retraction of the hydraulic cylinder 6, so that the gripper 5 can clamp the cable in a suitable position, and at least one side of the gripper 5 is in contact with the cable to prevent the cable from falling off.

[0020] The housing 1 also includes a control unit with an automatic operation program to achieve automated control of the motor 12 and hydraulic cylinder 6. It also includes an external manual control unit to clamp the cable when it is being threaded and to release the cable after traction is finished, so as to ensure the stability of the equipment during operation.

[0021] Compared with the prior art, this utility model has the following advantages: it changes the traditional roller traction method to a gripper moving traction method, which greatly increases the contact area with the cable, avoids the cable slipping during traction, thereby improving traction efficiency and reducing cable slippage damage.
