Abstract

The invention discloses a mechanical gear shifting driving device and a using method thereof, and belongs to the technical field of anchoring drilling machine equipment. The mechanical gear shifting driving device comprises a driving motor, a shell, a driving gear, a sun gear, an annular inner gear ring, a planet carrier, a sliding sleeve, a driving sleeve, a main shaft, a gear shifting device, a first bearing set, a second bearing set, a third bearing set, a second gear shifting inner tooth, a fourth bearing set, a fifth bearing set, a sixth bearing set, a first support, a second support, a pin shaft, a planet gear, a first gear shifting inner tooth, a gear shifting outer tooth, an annular edge, an inner sliding tooth, a seventh bearing set, an outer sliding tooth, a clamping plate, a shifting fork, a gear shifting oil cylinder, a groove and a notch. The using method mainly comprises the following use steps of preparation before use, first-stage transmission ratio working process testing, second-stage transmission ratio working process testing, free switching of different transmission ratios and use ending. Under the condition of a certain structural scale, free switching between a small size, a large gear ratio, a high rotating speed state and a low-speed and large-torque state is achieved.

Description

technical field [0001] The invention relates to the technical field of anchor drilling rig equipment, in particular to a mechanical shifting drive device and a method for using the same. Background technique [0002] The mechanical shifting of the power head of traditional construction machinery, especially in the design of the power head of the anchor drilling rig, generally shifts gears in the form of different gear ratios under the same level of transmission. The larger the gear ratio of the deceleration form, the larger the volume of the power head. Theoretically, the transmission ratio between two gears can exceed 2, but when the transmission ratio between two gears exceeds 2 times, the structural volume basically does not allow this solution to be applied to the field of anchor drilling rigs, that is, under the premise that the motor output speed has an upper limit, It is difficult to balance high-speed low-torque and low-speed high-torque. [0003] The output speed ...

Problems solved by technology

The first method is generally not ideal due to the limitation of the upper limit of the motor speed when taking into account the high speed. Although the second method can more easily take into account the parameter requirements of low speed, high torque and high speed, it is necessary to connect more motors in parallel. Adding more pipelines, control valves and motor leakage compensation devices increases the complexity of the hydraulic system and increases the overall cost and failure rate of the equipment

[0004] To sum up, the power head of anchor drilling rigs in the market is still not perfect, and there is no equipment that can meet the requirements of high speed, low torque and low speed, high torque at the same time. Therefore, the present invention proposes a mechanical shift gear on this basis. Driving device and method of use thereof to solve the above problems
