Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing:
[0017] Such as figure 1 As shown, a new type of high-efficiency and convenient drilling rig includes a walking self-loading and unloading mechanism 1, and also includes a mechanical transmission mechanism 2 and a hydraulic transmission mechanism 3. The mechanical transmission mechanism 2 includes a diesel engine 21, an automobile gearbox 22, a dual-input gearbox 23, Combiner 24, angle commutator 25, transmission twist hexagonal rod 26, power head 27; hydraulic transmission mechanism is composed of double oil pump 31, small hydraulic winch 32, oil cylinder 34 for drill pipe shackle and oil cylinder 35 for lifting and feeding; The small hydraulic winch 32 is connected to the automobile gearbox 22 and the double-input-end gearbox 23 in the mechanical transmission mechanism 2 through the universal joint coupling 4 . The walking self-loading vehicle mechanism 1 includes a hydra...

The invention provides a drilling machine. A power head of the drilling machine rotates and is directly driven through a mechanical transmission mechanism. Power output by a diesel engine is transmitted to the power head through a transmission, a corner commutator and a torque-transmission hexagonal rod to drive a drill pipe to rotate, transmission efficiency is high, and power choices are small. The mode that a power head is driven through a full-hydraulic power head drilling machine hydraulic motor is avoided, a long stroke speed multiplying mode is selected, an oil cylinder is used for pulling a chain to drive the power head to achieve ascending, descending and feeding along a guide rail on a drill tower, the effective stroke is 3.4 meters, and the drilling stroke is large. The mode that the drill pipe is hoisted and additionally arranged under assistance of a small hydraulic winch can be selected. Compared with a traditional mechanical vertical shaft drilling machine, the drilling stroke is only larger than one meter, the drilling machine needs to be moved backwards when the drill pipe is additionally arranged, and the efficacy of a winch is greatly improved in the mode that an elevator hoists and additionally arranges the drill pipe.
Description
technical field [0001] The invention belongs to a drilling rig, in particular, it is a drilling rig which combines the advantages of a mechanical vertical shaft drilling rig and a full hydraulic power head drilling rig. Background technique [0002] At present, when the traditional mechanical vertical shaft drilling rig is working, although the mechanical transmission efficiency is high, the vertical shaft drilling stroke is short. When adding and lifting the drill pipe, the drilling rig needs to be moved away from the wellhead, and the hoist lifts the drill pipe through the hoist, which is time-consuming The full-hydraulic power head drilling rig realizes long-stroke drilling and is simple and convenient to add and lift drill pipes, but it cannot avoid the disadvantages of low hydraulic system efficiency and large power loss; in addition, traditional full-hydraulic drilling rigs are driven by hydraulic motors The power transmission method of the power head requires the hydr...
