Description

Technical Field

[0001] The utility model relates to the technical field of cable traction, in particular to a cable traction device convenient for fixing. Background Art

[0002] The traction methods of cables are generally divided into two types. One is to fix the end of the cable and drag the cable through a traction device, and the other is to transport the cable through a wheel or crawler traction machine; the wheel or crawler traction machine mainly clamps the cable by the wheels or crawlers on both sides, and the cable is transported by the movement of the wheels or crawlers through friction.

[0003] For example, Chinese Patent CN111348477B discloses a cable traction device. The lower support wheels of the device are two frustum-shaped wheels that can move towards each other. The distance between the two frustum-shaped wheels is adjusted by a driving device, so that the device can be applied to cables of various specifications.

[0004] However, when the cable is being towed, the rear end of the cable is not always on the same horizontal line as the towing direction. To avoid the cable rubbing against the side wall of the towing machine during towing, it is usually necessary to additionally set up guide wheels perpendicular to the towing wheels, and the presence of the guide wheels makes it difficult to put the cable into the towing machine.

[0005] Based on this, the utility model designs a cable traction device convenient for fixing to solve the above problems. Content of the Utility Model

[0036] Example 2

[0037] like Figures 1-5As shown, as a preferred embodiment of the present utility model, the adjusting assembly 5 includes a second motor 51, a threaded rod 52, a limiting rod 53 and a moving frame 54. The second motor 51 is fixedly installed on the inner top of the frame 1. The threaded rod 52 is rotatably installed inside the frame 1, and the limiting rod 53 is fixedly installed inside the frame 1. The output end of the second motor 51 is in transmission connection with the threaded rod 52 through a second transmission assembly 55. The moving frame 54 is in threaded connection with the threaded rod 52 through a threaded sleeve, and the moving frame 54 is in limiting sliding connection with the limiting rod 53;

[0038] There are two limiting rods 53, and the two limiting rods 53 are symmetrically distributed on both sides of the threaded rod 52.

[0039] The main body assembly 61 includes a first guide wheel 611, a rotating frame 612 and a second guide wheel 613. The first guide wheel 611 is rotatably installed at the rear side of the frame 1, and the upper end of the rotating frame 612 is rotatably installed at the inner top of the front side of the frame 1. The second guide wheel 613 is rotatably installed on the rotating frame 612;

[0040] The main body assembly 61 further includes a baffle 614. The baffle 614 is fixedly installed at the inner bottom of the front side of the frame 1, and the baffle 614 abuts against the rotating frame 612.

At the same time, the cable is guided by the first guiding wheel 611 and the second guiding wheel 613, avoiding the horizontal movement of the cable between the driving wheel 3 and the driven wheel 4, which affects the cable conveyance and causes unnecessary wear.
