Drilling rigs are mainly used for deep hole drilling in geological prospecting, hydrological wells, coal geological exploration, oil and natural gas exploration and development, and play an important role in national economic construction. However, there are at least the following problems in the existing drilling rigs in China: when measuring the hole depth, the existing drilling rigs are calculated according to the length of each drill pipe multiplied by the number of drill pipes used, which is time-consuming, laborious and prone to errors.
Contents of utility model
In view of the above problems, the utility model provides a control system and a drilling rig for fast and effective depth measurement.

Specific implementation mode
Referring to figure 1, the control system of the drilling rig provided in the embodiment of the application is applied to a core drilling rig with a main winch equipment and a power head. The control system comprises: a pulse sensor 1 arranged in the main winch equipment and a pull rope arranged on the power head Displacement sensor 2. Power head side position switch 3, chuck switch 4, gripper switch 5 and controller 6, wherein pulse sensor 1 and Rope displacement sensor The input and output ends of the controller with the same name are respectively connected with the input and output terminals of the switch with the same name and the input and output ends of the switch.
The control system of the drilling rig provided by the embodiment of the application can include two kinds of sounding: the power head pull wire sensor sounding and the main winch pulse sensor sounding
(1) When the side position switch 3 of power head is closed (middle position of power head) and chuck switch 4 is closed, the drill bit is in drilling state of power head, and the sounding of power head is effective, it is driven by power head Rope displacement sensor 2. Calculate the depth;
(2) When the power head side position switch 3 is on (power head side position) or chuck switch 4 is on, the drill bit is in the winch state, and the main winch sounding is effective, then the depth is measured through the pulse sensor I count on the crown pulley used for wire rope transmission in the main winch equipment;
It should be emphasized that in any case, only when the gripper switch 5 is turned on can the depth measurement of the drilling rig control system be effective, otherwise it will be invalid.
The application also provides a drilling rig, including a main winch equipment and a power head, and a control system in any of the above embodiments.
It can be understood that in the embodiment of the present application, corresponding software is provided in the controller 6. In the actual structure, ttc60 controller can be used, and the data of each sensor can be transmitted by wireless, such as GPRS.
According to the above technical scheme, a control system and a drilling rig provided by the application can be driven by a power head when drilling Rope displacement sensor The drilling rig is easy to operate, convenient and practical, intuitive and reliable, and can greatly reduce the labor intensity.
