Rotary Drilling rig: you need to know the things!

 Drill in foundation engineering construction, has the irreplaceable important role.It is essential to modern construction and engineering equipment.As a result, the operation of the pile driving machinery safety must cause attaches great importance to.The following work instructions of the rotating drill, for all to share:

Three, use matters needing attention
1, start the engine, after 3 to 5 minutes should be a low speed, and under the no-load rotational power head, for the hydraulic system to work normally.
2, drill in the process of work, the operator should always observe all kinds of instrument is normal, if any abnormal situation should be timely stop it for checking.
3, pay special attention to the operation control handle to reach the designated position, in order to avoid the pressure impact to the system.
4, in use process should check the fastening bolt pressure vibration of pipe joint and oil pump, ensure no oil leakage, leakage phenomenon.
Five videotapes, drill must by specialist command, paying special attention to high tension line, water and other dangerous places.
6, within the scope of rotary drilling rig it is forbidden to stand.
7, drill in the transfer process, the flat car car must be opened immediately after the crawler walking.
8, check the hydraulic oil, must wait for the hydraulic oil cooling rear can be carried out.
9, electric welding rod parts, must turn off the power switch.
10, regularly check the swivel joint.


A, drill installation and removal:
1 prior to the demolition, drill installation, must by mechanical technicians according to the operating instructions of the manufacturer specific installation and disassembly process, scheme and technical safety measures, and strictly implemented.
2, hoisting by professional hoisting command structure, select wire rope according to the specific weight.In strong winds, heavy rain or hoisting under the condition of visibility, it is forbidden to drill installation, disassembly operations.
3 shall be provided to the drill, drill installation of base level and secure.
4, after the installation to detect and adjust the verticality of drill stand, drill pipe center deviation should be meet the requirements of construction technology.
Second, check the preparation before spud
1, all bolts should be complete, intact, tighten.
2, with wire rope as the medium of drilling rig and the condition of wire rope and lubrication and maintenance. It should be meet the requirements, deal with wire rope for appearance inspection, once a week at least once a week for a comprehensive and detailed inspection.
3, the hydraulic oil tank, advocate complementary drilling rig rotary table, power head, and the oil level height of the fuel tank should be within the scope of the use of the specification, when should be added in time.Check the oil, oil metamorphism is found, should be replaced immediately all.
4, oil absorption cut-off valve, oil return valve should be in the open position.
5, connection should be stable, no oil leakage.
6, check the components and complete in good condition, reliable connection, good insulation.
7, clear sundry pile hole, especially metal accessories.
8, equipped with the mud pump, electric welding machine, air compressor, etc should meet the requirements of drilling rig used.
