Cable heating device and cable heating method

Abstract

The invention relates to a cable heating device and a cable heating method. The device comprises a constant-temperature box, a bolt column and a chute frame, and cable racks are arranged on the two sides of the interior of the constant-temperature box. The top ends of the cable racks are connected with limiting bolts; cable routing frames are arranged on the inner sides of the limiting bolts; fastening columns are arranged on the sides of the cable routing frames; sleeve frames are arranged at the top ends of the limiting bolts; and limiting plates are connected to the two sides of the sleeveframes. A protective frame is mounted at the top ends of the limiting plates; a ring frame is arranged on the inner sides of the cable routing frames; the middle part of the ring frame is connected with a rotating frame. The device has beneficial effects that: when a cable between the constant-temperature box passes through the space between the cable routing frames, the cable can slide along thespace between the arc-shaped frames and the rubber wheels, so that the rubber wheels between the arc-shaped frames are tightly attached to the surface of the cable; and the surface of the cable is prevented from being abraded in the straightening process when the bent cable is straightened, and movement of the cable in the heating process is facilitated.

Description

technical field [0001] The invention relates to the technical field of cable heating devices, in particular to a cable heating device and a cable heating method. Background technique [0002] The cable heating device needs to heat and deform the cable, laying the cable: the temperature is required to be not lower than 0 degrees Celsius, such as now: >0 degrees during the day, <0 degrees at night, if the cable is placed outside at night, even if the temperature rises during the day, you can’t For construction, the correct way is to put the cable in a room with a constant temperature > 0 degrees at night, and take it out for laying when the temperature is > 0 degrees during the day. For the cable head, there is a special heating belt, and the constant temperature and time are regulated, but the cable in the cable heating device is bent, so the structure of the cable heating device needs to be improved. [0003] The cable heating device on the market is difficult t...

Problems solved by technology

[0004] The object of the present invention is to provide a cable heating device and a cable heating method to solve the problem that the cable heating device on the market proposed in the background art above is difficult to straighten a bent cable, and the surface of the cable is severely worn during the straightening process, and the cable During the heating process, there is no corresponding wiring structure, which will easily cause the cable to be straightened and entangled, making it difficult to transport the cable heating device as a whole
