Description

Technical Field

[0001] The present application relates to the technical field of support frames, and in particular to a support frame for laying cables. Background Art

[0002] The cable drum is a wire drum for winding cables. In cable laying, multiple cable drums are usually transported to a designated location for stacking, and a support frame is set up at the construction site. The cable drum is then hoisted. The cable drum has an inner hole at the axis. A steel pipe is passed through the inner hole of the cable drum and inserted into the support frame, so that the cable drum is suspended in the air and can rotate relative to the support frame. Finally, the staff pulls the cable from the cable drum to rotate the cable drum, which is convenient for the cable unwinding operation.

[0003] Cable reels are usually placed vertically at construction sites, that is, the axis of the cable reel is parallel to the ground. In order to reduce the rolling of the cable reel, wooden blocks or stones are usually placed on the cable reel to support it. However, there may be situations where the supports cannot prevent the cable reel from rolling. For example, if the construction site has a gentle slope, it is easy to cause the position of the cable reel to be unstable. In this case, the cable reel is usually placed horizontally, that is, the axis of the cable reel is perpendicular to the ground, so as to improve the stability of the cable reel.

[0004] For a flat cable drum, if it is installed on a support frame, it is necessary to hoist the cable drum and adjust its posture so that the axis of the cable drum is parallel to the ground again, and then the cable drum can be passed through a steel pipe and installed on the support frame. However, the cable drum is large in size and weight, and needs to be hoisted with the help of additional hoisting equipment. It is also necessary to adjust the posture of the cable drum after hoisting, which makes the operation cumbersome and brings inconvenience to the unwinding operation of the cable drum.
