Description

Technical Field

[0001] The invention relates to the technical field of cable production, and in particular to a passive wire-laying electrical control system. Background Art

[0002] The existing passive wire-paying control system can only generate one tension output through the digital tension controller in the same manual operation, that is, the tension value of the magnetic powder brake during operation is used when the machine is stopped. At the same time, the tension required for the wire-paying reel during shutdown is adjusted by manual reaction speed. After the tension is instantly increased, the magnetic powder brake lacks time protection, and will produce large losses under long-term high-voltage shock. The stability of the tension control cannot be guaranteed. When the wire-paying reel is fully loaded, due to the large inertia, it will rush forward, causing a large number of collapsed and disordered copper wires. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a passive wire-laying electrical control system, which can freely switch the stopping mode of wire-laying and is stable and reliable.

[0004] The above technical problems to be solved by the present invention are achieved through the following technical solutions:

The normally closed contact K1 of the running relay K1, the normally open button SB3 and the normally closed normal stop button SB2 are synchronous buttons, the branch where the emergency stop relay K4 is located is connected in series with the normally open emergency stop button SB4, the branch where the time relay T2 is located is connected in series with a parallel circuit composed of the normally open contact K3 of the normal stop relay K3 and the normally open contact K4 of the emergency stop relay K4, the line-release brake circuit is provided with the normally open contact T2 of the time relay T2, the voltage output circuit is provided with the connection contact ADJGND of the magnetic powder brake, the connection contacts are respectively connected with the normal operating voltage, the normal parking high voltage and the emergency stop high voltage, and the voltage output circuit is provided with an interlocking circuit structure.

This structural design allows the normal operating voltage, the normal parking high voltage and the emergency parking high voltage to be interlocked, ensuring that the magnetic powder brake can only be connected to one voltage.

[0007] Preferably, the two ends of the normally open emergency stop button SB4 are connected in parallel with a meter counting completion trigger switch CNH. The meter counting completion trigger switch CNH plays the role of automatic meter counting emergency stop.

[0008] Preferably, a buzzer BR is connected in parallel to both ends of the emergency stop relay K4, and the buzzer BR serves as an alarm prompt.

[0009] Preferably, a stop indicator light HL1 is connected in parallel to both ends of the time relay T2. The stop indicator light HL1 serves as a status prompt.

[0010] Preferably, a series circuit consisting of a normally open contact K1 of the operating relay K1 and an operating indicator light HL2 is connected in parallel at both ends of the series circuit of the normally open operating button SB1 and the operating relay K1. The coordinated structure of the normally open contact K1 of the operating relay K1 and the operating indicator light HL2 serves as a prompt of the operating status.

[0011] Beneficial effect: After adopting the structure described in the present invention, the switching between normal parking and emergency parking is realized by converting the two input voltages of the magnetic powder brake, and the instantaneous high-voltage time protection of the time relay makes the system stable and reliable.
