Engineering drilling rig in the event of failure, a serious impact on the progress of the project and do engineering rig maintenance work is necessary, to pay more attention when removing drilling rig used to make more long-term. ①, when part removal, you should first remove the locating pin then the other demolition work, and the installation should be in the position aligned first with the positioning pin, and then install other components; must be protected when ②, oil pipeline disassembly connectors; ③, the oil pipe joints should minimize the number of demolition to avoid leakage; when ④, demolition and erection works hard hit when casting rig ban tunnel drilling rig where to sell against other parts, should be fitted wood or copper block ; ⑤, before installation, the parts must be cleaned with kerosene 2015 tunnel drilling rig, clean and painted enough oil (or grease); ⑥, damaged or worn parts must be replaced; ⑦, engineering rig removal or replacement When the bevel gear must be accurately adjusted well bevel gear meshing clearance and check the bevel gear contact pattern along the tooth height and tooth length are less than 40%, then fill in the amount of grease. Rig load and consider the use of engineering geological condition of the building, and the pile foundation bearing stratum design on the base rock pile capacity increase tunnel drilling rig equipment can also be equipped with a variety of specifications drill, this series of drill rigs machines for complex infrastructure construction gravel, cement and gravel embedded in rock, widely used in bridge bored piles, diaphragm wall foundation engineering. But also to a higher pile foundation construction requirements, high rotary drilling rig construction costs, but also unable to meet the gravel, boulders, stone, rock, construction difficult, the case is easy to hole collapse, 1990s mid-pile factory to meet market requirements, eggs are used in construction Gravel drilling machine forward, due to the impact force is large, easy to collapse hole, filling coefficient is too large, we developed a drilling machine machine to meet the requirements of Pile Foundation Construction . Tunnel drilling rig where to sell _ _ Mashan tunnel drilling rig provided by Luoyang Prius Prius Drilling Equipment Co., Ltd. Road Zhiyuan, temper forward. Luoyang Prius Drilling Equipment Co., Ltd.
