Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0018] like figure 1 and figure 2 Shown, a kind of drilling rig with motor as the main power, it includes at least two motors 1, fan 11, shaft coupling 2, hydraulic coupling 3, and carriage 4, drawworks 8, drilling rig 9 and diesel engine 12, motor 1 It is a HTB02C horizontal, single-shaft extension, three-phase squirrel-cage variable-frequency speed-regulating asynchronous motor with double-bearing support structure. A fan 11 is installed on the motor 1. The main shaft of the fan 11 is connected with the main shaft of the fan motor 10. The motor 1 adopts a high-speed High-quality imported bearings and long-term grease have a maintenance-free period of up to three years. The motor adopts forced ventilation and has its own fan 11. The fan 11 is driven by the fan motor 10. T...

Abstract

The invention relates to a drilling machine using motors as a main power. The drilling machine comprises at least two motors (1), fans (11), hydraulic couplers (3), a compounding transmission (4), a winch (8), a drilling machine body (9) and a diesel engine (12), wherein each motor (1) is provided with one fan (11), the output end of each motor (1) is connected with each hydraulic coupler (3), each hydraulic coupler (3) is connected with the input end of the compounding transmission (4), the output end of the winch (8) is connected with the drilling machine body (9), the diesel engine (12) is connected with each motor (1) in parallel, the output end of the compounding transmission (4) is connected with the winch (8), the output end of the winch (8) is connected with the drilling machine body (9), each motor (1) is an HTB02C frequency-variable and speed-adjustable asynchronous motor, and the compounding transmission (4) is connected with two sludge pumps (5). The drilling machine has the advantage that the motors is are used as the main power, and the diesel engine is used as a standby power, so the adaptability is high, the energy consumption is low, the maintenance cost is low, the environment-friendly effect is realized, and the control is accurate.

Description

technical field [0001] The invention relates to oil exploration and drilling equipment, in particular to a drilling rig powered by a motor. Background technique [0002] In recent years, with economic globalization and the rapid development of the domestic economy, China's oil consumption has been second only to the United States, ranking second in the world. At the same time, due to the serious shortage of domestic oil production capacity, energy conservation is a long-term development strategy for my country's sustainable development and a basic national policy of our country. my country's demand for petroleum energy is increasing year by year, and oil exploration is becoming more and more intensive. Oil exploration and drilling equipment should meet the requirements of energy conservation. At present, many drilling sites are located in densely populated areas. While the operation of diesel generator sets generates huge power, it also produces more than 122dB of noise and...
