Rail installation requires electric flatbed trucks to be different from general track installation, and its working principle is: when installing the track, in order to obtain a certain resistance, the flatbed truck should be away from the other end.
Process features:(1) According to the insulation requirements of flatbed tracks, the bolts are treated with sulfur impregnation insulation, and the insulation elastic pads are installed under the rail pressure plate, which effectively improves the insulation resistance between the tracks. (2)Due to rail corrosion and the complexity of the rail environment, the resistance value measured by equipment such as instruments is not the true value. The test of the resistance value of the welder is summarized in practice.
Process and operation points: First, remove the loose concrete and stones at the bottom of the equipment and around the electric board, and then clean the debris in the reserved holes, and then clean the orifices with a hair dryer. After the steel bar is left in the hole leak, it should be treated in time to ensure that the steel bar does not contact the embedded parts. Screw electric flatbed truck
1) Bolt insulation treatment: In order to ensure the wetness of the bolt insulation, sulfur melts, the threaded part under the screw is soaked with sulfur.
2)The specific method of bolt installation is as follows: oil and rust on the anchor bolt must be removed. (2) After the screw is inserted, the top height is corrected horizontally and fixed.
3) The proportion of water in the slurry cannot exceed the recommended dosage, and the specific dosage is determined according to the needs of the site.
4) The anchor bolt grouting material should meet the following conditions: the mixed grouting material flows into the bolt hole, vibration occurs, the grouting cannot be adjusted, and the water cannot be directly absorbed after grouting.
