Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments.
Reference numerals in the drawings of the specification include: the device comprises a shell 10, a wire coil 20, a first supporting rod 21, a motor 22, a storage battery 23, a manual switch 24, an infrared receiver 25, a charging interface 26, a friction block 30, a fixed pulley 40, a second supporting rod 41 and a threading pipe 42.
Example 1:
an automatic take-up and pay-off device for an arrester live test is shown in figures 1-2 and comprises a shell 10, a wire coil 20, a fixed pulley 40, a motor 22 and a storage battery 23, wherein the shell 10 is cuboid, the shell 10 is made of reinforced ABS (acrylonitrile butadiene styrene) materials with metal shielding layers, and a wire outlet hole is formed in the shell 10; the wire coil 20 is rotatably connected to a first supporting rod 21 fixed at the bottom of the shell 10, a friction block 30 which has a limiting effect on the wire coil 20 is fixed at the top of the inner side wall of the shell 10, the friction block 30 is made of rubber, the motor 22 is fixed on the inner side wall of the shell 10, and an output shaft of the motor 22 is connected with the right end of the wire coil 20 through a torsion limiter; motor 22 electric connection has battery 23, and battery 23 fixes at the top of shell 10, and hand switch 24 and automatic switch are installed to the top of battery 23, and hand switch 24 and automatic switch set up to double control switch, and automatic switch is infrared receiver 25, and infrared receiver 25 passes through controller and battery 23 electric connection, and infrared receiver 25 pairs has infrared transmitter, and infrared transmitter installs on remote control board (current).
As shown in fig. 1-2, the wire coil device further comprises a fixed pulley 40, the fixed pulley 40 is fixed at the bottom of the housing 10 through a second support rod 41 and is located below the front side of the wire coil 20, the wire coil device further comprises a threading pipe 42, the threading pipe 42 is located below the front side of the fixed pulley 40, and the threading pipe 42 is in an L shape.
One wire coil 20, one motor 22, one fixed pulley 40 and one storage battery 23 constitute one take-up and pay-off unit, and the number of the take-up and pay-off units in this embodiment is set to 3 and arranged at regular intervals outside the housing 10.
The shell 10 is also provided with an inlet hole, one end of the cable is fixed with the wire coil 20 and penetrates out of the inlet hole, and the other end of the cable is wound on the wire coil 20 and penetrates out of the outlet hole after sequentially passing through the fixed pulley 40 and the threading pipe 42. When the invention is not used, the friction force of the friction block 30 on the wire coil 20 has a limiting effect on the wire coil 20.
When the cable needs to be used, one end of the cable, which is positioned outside the wire outlet hole, is pulled by hands, the pulling force overcomes the friction force of the friction block 30 on the wire coil 20 so as to drive the wire coil 20 to rotate, the motor 22 is not electrified at the moment, so that the wire coil 20 can rotate under the drive of the wire coil 20, when the length of the cable meets the requirement, a worker does not apply the pulling force any more, and the friction block 30 limits the wire coil 20; thereby realizing the locking of the cable;
after the cable is used, a worker manually presses a manual switch 24 of a storage battery 23, a motor 22 is electrified, the motor 22 rotates to drive a wire coil 20 to rotate reversely to wind the cable, and after the cable is wound, the worker loosens the manual switch 24 and cuts off the power of the motor 22; or the worker sends out an infrared signal by using an infrared transmitter button on the remote controller, and the infrared receiver 25 controls the motor 22 to be powered off by the controller after receiving the signal.
In the process of taking up the wire, if the wire is wound or knotted, or the motor 22 is not stopped in time after the wire is taken up, the wire is easily damaged, so in this embodiment, the output shaft of the motor 22 is connected with the right end of the wire coil 20 through the torque limiter, when the torque of the motor 22 to the wire coil 20 exceeds a set value, two ends of the torque limiter slip, so that the motor 22 idles, the wire coil 20 does not move, and the wire is not damaged, at this time, the motor 22 is powered off in time by using the manual switch 24 or the remote controller, the motor 22 is not powered on at this time, so the motor can rotate under the driving of the wire coil 20, the torque of the motor 22 to the wire coil 20 disappears, and two ends of the torque limiter automatically recover to be connected.
If under the condition that the cable twined or the cable knotted, the manual work is separated the cable or open the knot after, it can to receive the line again.
The threading pipe 42 is matched with the fixed pulley 40, so that no blocking phenomenon exists in the wire winding process, friction of a test cable is reduced, and the wire winding process is stable and does not wind.
In order to avoid the wire rewinding, the end of the cable is also retracted into the housing 10, which is inconvenient for the next wire rewinding, and therefore, in this embodiment, a clamping block with a size larger than the wire outlet hole is fixed at the end of the cable, so as to limit the end of the cable.
The test wire adopts the PE wire originally used by the tester, so that the transmission stability of the test signal of the tester is ensured, and the signal is not attenuated. The charging interface 26 on the storage battery 23 is arranged to facilitate charging of the storage battery 23 by a charger; when the test wire is not used, the test wire is completely stored in the aviation case, so that the conditions that the test wire is wound and pulled or exposed outside to cause damage, aging and the like are avoided.
The total length of the cable in this embodiment is 10m, so the paying-off length can be changed within 0-10 m at will, the paying-off speed can be manually controlled, the take-up speed is set by setting the rotating speed of the motor 22, and the take-up speed in this embodiment is 0.35 m/s.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
