Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a cable support frame. Background Art

[0002] For aesthetic reasons and cable protection, cables in cities are buried underground in cable trenches as much as possible. After the cable trench is constructed, lawns will be laid on top of it. A maintenance well will be set up at regular intervals in the cable trench for cable maintenance. When a new cable needs to be replaced or laid during maintenance, a traction rope must be inserted first, and then the cable is pulled from one maintenance well to another. During the pulling process, the cable will rub against the edge of the maintenance well and the top plate of the cable trench, and the outer sheath of the cable is prone to wear. During long-term thermal expansion and contraction and self-aging, the worn parts are prone to leakage accidents.

The movable wheel 63 is mounted on the movable block 64 through a rotating shaft. The movable wheel 63 is connected to one end of the guide rod 65. The other end of the guide rod 65 passes through the end plate of the mounting frame 61 and is connected to the stopper 67. The spring 66 is arranged on the guide rod 65 between the movable block 64 and the end plate of the mounting frame 61. The sides of the bottom wheel 62 and the movable wheel 63 are both provided with a circle of arc grooves. The movable block 64 can drive the movable wheel 63 to move toward the bottom wheel 62 and fit with the bottom wheel 62 under the action of the spring 66. During operation, the cable is passed through the gap between the bottom wheel 62 and the movable wheel 63 on the two guide units 6 in turn, so that the vertical turning of the cable can be achieved, and the turning point of the cable can be protected at the same time. The cable support frame has a simple structure, is easy to operate, and has a low manufacturing cost. The two sides of the movable block 64 fit with the inner sides of the two side plates of the installation frame 61. By setting the two sides of the movable block 64 to fit with the inner sides of the two side plates of the installation frame 61, the movable block 64 can be limited to prevent it from rotating, thereby ensuring that the movable wheel 63 is always facing the bottom wheel 62, achieving functional requirements while simplifying the structure. The turning unit 1 also includes a reinforcing rod 7, and the two ends of the reinforcing rod 7 are respectively connected to the two ends of the two guide units 6 that are separated.
