Abstract

The invention relates to an interlocking type gear shifting mechanism applied to a gear box. Output rotary speed conversion and forward and backward rotations (four gears of different forward rotary speed outputs and backward rotary speed outputs) of a drilling machine are controlled by the same pulling rod; a positioning steel ball and an interlocking steel ball commonly press and firmly lock a gear in a conversion process and an inter-gear interlocking function is realized, so that the gear shifting is safe and reliable and gears are not disordered, and the inter-gear interlocking function is simply and reliably realized in a gear shifting process; and compared with the existing gear shifting mechanism lacking of the interlocking function, the interlocking type gear shifting mechanism has the advantages of simple and compact structure, easiness in operation, and safety and reliability, and is suitable for being popularized and applied on similar gear boxes.

Description

technical field [0001] The invention relates to an interlocking shifting mechanism applied to a gearbox, specifically a device for shifting positioning and interlocking between gears when the gearbox shifts gears, which controls the output speed conversion of the drilling rig through the same shift rod It rotates forward and reverse, and between the five gears, the positioning steel ball and the interlocking steel ball are pressed together to firmly lock the gear and realize the interlocking function between gears. It belongs to the field of drilling rigs in the construction machinery industry. Background technique [0002] In the field of drilling rigs in the construction machinery industry, the role of the gearbox is to change the output speed and realize forward and reverse rotation. The traditional speed change mechanism is complex, has many overlapping mechanisms, and is difficult to maintain, so it is not suitable for the harsh construction conditions of the drilling r...
