Detailed ways

The technical solution of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

As shown in Figures 1 and 2, the electro-hydraulic cable pay-off mainly includes a pay-off reel 2 and two supports 1, the pay-off reel has a central hole, and a main shaft 6 is installed transversely between the two supports. The pay-off reel is installed on the main shaft and is located between the two supports; the end of the main shaft is located on the support bar provided on the support, and a hydraulic jack is installed on the two supports, and the top of the hydraulic jack is against the lower part of the support bar; An electric mechanism 4 is installed. The electric mechanism is composed of a three-phase AC asynchronous motor and a reducer connected to the motor. The output shaft of the reducer is fixed with a driving gear, and a driven gear meshing with the driving gear is installed on the main shaft; the three-phase AC The asynchronous motor adopts three-phase AC 380V grid power supply, and the three-phase AC 380V grid power supply is connected to the three-phase AC asynchronous motor through the control switch box; the remote control mechanism of the three-phase AC asynchronous motor is composed of a wireless remote controller and a control box installed at the end of the motor. A three-phase AC relay, a wireless receiving module for receiving signals from a wireless remote control, and an AC/DC inverter are installed in the control box. Connection, the remote control receiving module is connected with the control circuit of the three-phase AC relay, and three sets of three-phase AC relays are connected with the motor to control the forward, reverse and stop of the motor respectively.

An overcurrent protection circuit module is connected in series between the above-mentioned three-phase AC asynchronous motor and the three-phase AC 380V power grid. Double judgment, automatically cut off the working power of the electro-hydraulic cable pay-off motor mechanism, so as not to burn electrical components, protect the motor and other equipment safely, and use it more at ease.

When it is necessary to lay the cable, under the action of two hydraulic jacks, lift the main shaft and the pay-off reel to ensure that the cable rotates around the main shaft of the pay-off reel; the three-phase AC asynchronous motor is connected to the three-phase AC 380V power grid; The following two working modes are adopted:

Using the on-site control mode, press the "pay-off" button on the control switch box, the motor drives the reducer to start working, and the main shaft and the pay-off reel are driven to rotate through the meshing of the driving gear and the driven gear, and the cable starts to be unwound, and the cable is unwound The length of the distance is determined by the actual situation on site. When the laying distance meets the requirements, the staff press the "stop" button on the control switch box to complete the laying work of this cable, and then the next cable can be laid.

If the cable pay-off is too long, control the "take-up" button on the switch box to make the motor rotate in the opposite direction to carry out the work of taking up the cable.

Using the remote control mode, press the "Wire Release" button on the wireless remote control, after the wireless receiving module receives the signal, it will close the corresponding set of three-phase AC relays, drive the motor to rotate, and the motor will drive the reducer to start working. It meshes with the driven gear, drives the main shaft and the pay-off reel to rotate, and starts to lay out the cable. When the pay-off distance meets the requirements, the staff press the "stop" button on the wireless remote control to complete the laying work of this cable. Proceed to the laying of the next cable.
