The unipolar slip conductor is familiar with the overview and structural characteristics of all cranes. Then the length of the workshop is set according to the site's power input points. Then the installation procedure and requirements are listed using the unipolar slip conductors as an example:
step;
1) Install the trolley wire bracket, use the welding or expansion bolts to install the angle bracket on the track beam according to the specified spacing. The erection of the bracket is the key to the installation quality of the trolley wire, and it is an important link to ensure the flatness and usability of the trolley wire. The flatness of the bracket must be ensured on the entire line, the angle of extension of the angle steel is the same, and the angle steel must be parallel and cannot be skewed. The plane of the square hole angle steel is in a horizontal plane and the factory hole is on a line. Generally, the steel wire can be used. Pull line leveling and alignment. Light rail line spacing between two brackets <1.5m
2. Install the lifting rack on the angle bracket. Do not tighten the nut at this time, and then tighten after the trolley wire is installed and adjusted. Install the sliding wire connector jacket. Put the trolley wire in the bayonet of the lifting rack. (The heavy-duty cable clamp has been installed on the wire.) After the wire is installed, level it and tighten the nut of the pylon. Put the connector into the other end of the first set of wires, and install the second set of wire in the same way. 2. Connect the two contact wires with the connector, install the joint jacket, and level and tighten the single-pole trolley wire. Install all the trolley wires accordingly. Note that the joint should be smooth and the clearance should be less than 0.5mm.
3. Install the power input section.
Install the power input section according to the designed power supply mode, be sure to tighten, and then install the shield to fix the jacket clamp. According to the design program to install the fixed clamp, first-line two installed end of the jacket. Installed in the two ends of the trolley wire The end sleeve can also be installed before hanging.
Check. The entire trolley line should be carefully checked after installation. The trolley line should be straight and the spacing should be the same. The trolley line should be parallel to the crane rail. The deviation should be ≤ 5mm. The suspension should be tightened and the joint should be smooth.
4. Install the unipolar collector and its bracket. After the trolley wire is installed, the collector can be installed.
The center line of the current collector bracket must be at a distance of H=155mm from the lower plane of the lower sheath of the trolley wire, ie the current collector connecting rod must be horizontal when the contactor's contact shoe is placed in the sliding contact groove. M seat must be installed horizontally and Sliding lines are parallel. The line-contact groove slots must be in the same vertical plane as the vertical center line of the current collector.
Collector's cable and the electrical equipment of the cable connected. Note that before wiring, it should be routinely checked whether the motor insulation requirements meet the requirements, if found abnormal should be repaired or replaced.
5. Connect the power supply. Firmly connect the power cord to the power input section.
Commissioning. Should be no-load trial run, reciprocating operation several times back and forth, if there is no abnormality should immediately stop, cut off the power, check, troubleshooting.
