Description

The constant-tension cable reel device

Technical field

The utility model relates to the built on stilts a kind of device regulating and keep the mechanical tension technical field of installing of cable, relates in particular to a kind of vehicle-mounted constant-tension cable reel device.

Background technology

Cable drum in the market scarcely has the cable stretch controlled function, and in actual use, what cable had drags on the ground, and being suspended in of having is aerial, and cable can not be stretching, damages easily.Some producer is an energy control cable tension force, adopt torque motor or reel to adopt magnetic coupling type to realize the Tension Control of cable, be easy to make burn-down of electric motor when finding cable drum long-term work that torque motor drives in the practice, magnetic coupling type cable drum structure is huge, control is complicated, reliability is not high, and useful life is not long.

Summary of the invention

The purpose of this utility model has the cable drum above shortcomings of control cable tension force at existing, provides a kind of functional reliability height, the constant-tension cable reel device of long service life.

The purpose of this utility model is achieved through the following technical solutions, a kind of constant-tension cable reel device, comprise reel, built-in sliding ring current collector in the reel, support and unidirectional motor that spool shaft two ends frame is solid, it is characterized in that spool shaft one end connects helical gear---the bevel gear reductor that is provided with, be connected the permanent-magnet damper that is provided with between helical gear---the power shaft of bevel gear reductor and the output shaft of unidirectional motor, set up on the support of reel one side and homoaxial two-way spiral groove rotating shaft of reel and the strand oscillator that spins with it.

The utility model permanent-magnet damper that output torque is less is arranged between reductor and the motor, make permanent-magnet damper be operated in little moment of torsion, high-speed state, permanent-magnet damper when cable drum rolling cable as clutch, when the cable drum unwrapping wire, permanent-magnet damper is again as the damper of cable drum, in the use, mobile power consumption equipment pulls cable, cable makes the reel rotation, reel drives the reductor rotation, because the effect of permanent magnet damping, the power shaft of reductor is received the adjustable braking torque effect of permanent magnet damping, this braking moment makes cable drum stop operating when cable is not subjected to pulling force on the one hand, stop cable to glide, on the other hand, this braking moment makes the suffered tension force of cable do not exceeded permissible value, promptly can not make the suffered hightension excessively of cable and destroy cable, thereby realize permanent tension force.

The utility model sets up on the support of reel one side with the homoaxial two-way spiral groove rotating shaft of reel and reaches the strand oscillator that spins with it, strand oscillator is by the strand oscillator seat, the guiding voussoir, holddown spring, the embedding mother, roller and guide post constitute, the two ends of guide post are fixed on the support, the strand oscillator cover for seat is in the bidirectional screw rotating shaft, the guiding voussoir is pressed into the helicla flute of rotating shaft by holddown spring and locknut, roller is fixed on the side of strand oscillator seat, the solid drive sprocket of two-way spiral groove rotating shaft one end cover, drive sprocket and spool shaft one end overlap solid sprocket wheel through the driving-chain transmission, the bidirectional screw slot pitch is a twice cable winding pitch, and the nearly two ends of rotating shaft two-way spiral groove remittance place mutually adopts lead-over groove.After adopting abovementioned technology, when reel rotates, transmission by sprocket wheel and chain makes rotating shaft rotate by certain speed ratio, the guiding voussoir in axial direction moves in helicla flute, and the cable that is through between roller is done relative motion along with moving axially with the rotation of reel of strand oscillator, makes cable well-regulated coiling and discharging on reel.

The utility model also is provided with storage battery, charger and electric control panel on support; consider that the utility model uses vehicle-mounted power supply; so design has stand-by power supply; work as power cut-off; can be by the manual switching working power to the storage battery inverter, but cable drum automatic winding cable, and the cable rolling finishes; automatically cut off inverter, avoided the electric discharge phenomena of storage battery under the shutdown situation.
