Automatic Pile Connection Method for "Stainless Steel Lifting Column"
1. Reserved line for dynamic unit of road pile facility:
The motor of power unit of road pile is a three-core cable which is blue in turn. Brown thread, flower thread and solenoid valve are two black lines, with a warning lamp and a two-core spiral lamp line. There are seven lines and five lines without warning lamp. The connection begins after the welding of fixed steel bars in embedded barrels.
2. Wiring process:
The hydraulic integrator of the power unit is placed on the ground on the side of the basic ditch of the buried barrel, and the seven-core cable drawn from the top of the buried barrel is connected to the motor wire, battery valve wire and warning light line of the power unit respectively.
Accurately remember the line number or color of the seven-core wire and cable, and the corresponding line number color of the motor, battery valve and warning lamp in the facility, so as to avoid misconnection of the control box.
3. Facilities wiring instructions:
The motor wires on the pile are common to the blue motor, the brown motor and the marking motor, which can not be connected to the terminal corresponding to the control box.
Two separate black wires of the battery valve are connected to the common corresponding terminals of the control box battery valve and the battery valve, regardless of positive or negative. The warning light line is connected to the warning light of the control box and the public terminal of the warning light, regardless of positive or negative.
4. Wiring standards:
Wire ends should be welded by soldering tin, first wrapped with plastic tape, then wrapped with high-pressure waterproof tape, then wrapped with plastic tape, then wrapped with electrical asphalt tape, four times in total. After wiring is finished, the wiring at the wiring end should be regulated and fixed under the power unit to prevent external forces from pulling the wiring. Break.
After finishing, two wires connected to the warning lamp on the power unit are connected together. The other end of the cable is measured by a multimeter. Three wires are connected to the motor and two wires are connected to the battery valve.
Two light wires are connected, and the motor, battery valve and wire are not connected. After confirmation, the power unit is put into the buried barrel. For the fixed bolt under the buried barrel, the hydraulic power unit button can be rotated clockwise, and the remaining cable can be used with wooden sticks to standardize the site to the hydraulic power unit.
