Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides a kind of protective-cover type drag-line Anti-ice-and-snow device, makes drag-line Have both anti-rain wind induced vibration and freezing, deicing function;Heating cable is selectively constructed in cable body manufacturing factory or at the scene Cable body is wound in protective sleeve of pulling cable pipe surface after completing installation, cannot be only used for new cable body, can also be applied to existing bridge cable Maintenance, is conveniently replaceable when helix anti-ice, deicing function break down.
The technical solution of the utility model is as follows:
A kind of protective-cover type drag-line Anti-ice-and-snow device, including heating cable, power control apparatus, power supply, the heating cable It is connected to power supply or is disconnected by power control apparatus, further include protecting pipe, the protecting pipe is sleeved on drag-line;The heating Cable is wrapped in protective sleeve of pulling cable pipe surface;Winding heating cable in protective sleeve of pulling cable pipe surface can make drag-line have anti-rain wind induced vibration Effect realizes the freezing and deicing function on drag-line surface by the controllable heating electric cable heating of power control apparatus;Root According to the winding for needing may be selected in producer or site operation completion heating cable, replacement and Breakdown Maintenance conducive to old bridge drag-line.
Preferably, the heating cable uses spiral winding mode, winding side in the canoe of protective sleeve of pulling cable pipe surface Method is simple to operation, and anti-rain wind induced vibration effect is good.
Preferably, the heating cable uses one of carbon fiber heating cable or metallic cable.Carbon fiber heating electricity Cable has many advantages, such as that pressure-resistant fold resistance is strong, energy-saving effect is good and highly-safe;Wire rope manufacture craft is simple, at low cost.
Preferably, the resistance wire that the heating cable includes spiral rib and is embedded in inside spiral rib.Conducive to spiral Rib is packaged resistance wire, avoids resistance wire from being exposed to outer easy to damage, improves the heating job stability of cable and resistance to Long property.
Preferably, with protecting pipe in such a way that hot melt is combined, which to heat the spiral rib Cable is fitted closely with protective sleeve of pulling cable pipe, is bonded secured, not easily to fall off.
Preferably, power control apparatus includes remote control switch and intelligent temperature control device, the intelligent temperature control device and remote control Switch is electrically connected, and the intelligent temperature control device is arranged at intervals on heating cable.The intelligent temperature control device can monitor heating The heating temperature of cable and according to temperature automatic adjustment heat cable size of current or with the on-off of power supply, it is energy-saving.
The utility model has the beneficial effects that
The utility model makes drag-line have the same of anti-rain wind induced vibration by the built-in resistor silk in protective sleeve of pulling cable pipe helix When also have both freezing, deicing function;By the way that the helical wound of built-in resistor silk on protective sleeve of pulling cable pipe, is solved anti- It freezes, the limitation that deicing drag-line can only make in cable body manufacturing firm, can select as needed in producer or site operation Helical wound is completed, new cable body is applicable not only to, can also be applied to the replacement and maintenance of existing bridge cable, solve old bridge rope The problems such as anti-rain wind induced vibration of body and anti-freeze, deicing.
