Description

Technical Field

[0001] The utility model belongs to the field of petroleum geological exploration and drilling equipment, in particular to a temperature collection, processing and alarm system for a top drive gear system. Background Art

[0002] Top drive, also known as top drive unit, is the main equipment for oil drilling. It integrates mechanical, hydraulic and electronic control, and can independently complete the functions of loading and unloading drilling tools, rotary drilling, and pipe handling. The gear train is a speed reduction and torque increase device of the top drive. It is installed inside the gear box of the top drive body and generally consists of two stages of speed reduction. The power output of the main motor of the top drive is driven by the gear train to reduce speed and increase torque, and then drives the drilling tool to rotate, thereby achieving the final top drive power output.

[0003] With the increase of medium-deep wells, ultra-deep wells and horizontal wells in oil drilling, top drives have been used more and more widely. The gear train is the main power transmission device of the top drive. Since the gear train is located in the top drive body at high altitude, it is difficult for personnel to inspect it. In addition, the transmission load of the gear train is large, and it is very easy for the gear train to fail. After the gear train fails, it must be repaired in the factory, which not only causes serious economic losses, but also seriously affects the safety of drilling.

[0004] The Chinese invention patent application with publication number CN116246447A discloses a wireless control system for a top drive body, including a top drive controller, a top drive body, a top drive control communication device and a top drive execution communication device; the top drive control communication device communicates with the top drive controller via a serial port, the top drive execution communication device is connected to the top drive body, and the top drive control communication device and the top drive execution communication device are connected via wireless communication to realize signal transmission between the top drive controller and the top drive body. The above technology completely replaces the expensive and short-lived top drive travel signal and auxiliary electric power cable by wireless transmission, increases the protection and detection function of the solenoid valve fault, prevents the expansion of the fault, and reduces the difficulty of fault handling, but does not reduce the top drive gear system failure rate. The initial manifestation of gear system failure is abnormal gear system temperature. If the abnormal temperature change of the gear system can be collected and processed in time, and then early processing is performed, the top drive gear system failure rate can be greatly reduced.
