The gear box gear shifting device comprises a reduction gearbox body, a gear shifting gear set, a gear shifting control mechanism and a gear locking mechanism, the gear shifting control mechanism is provided with a handle, a transmission assembly and a shifting fork assembly which are arranged at the top of the reduction gearbox body, and the shifting fork assembly is arranged at the power output end of a power assembly; the handle is divided into a first section and a second section from a mounting hole of the handle, a locking plate is arranged on the handle close to the mounting hole, the locking mechanism is arranged at the top of the reduction gearbox body and is provided with a locking head matched with a locking hole, and a guide piece used for limiting the locking head is arranged on the top plate. The handle and the gear locking mechanism are arranged above the reduction gearbox body, external force can be transmitted to the shifting fork assembly in the reduction gearbox body through the transmission assembly, the shifting fork assembly shifts the gear shifting gear to move axially so as to achieve gear shifting, the structure is simple, the machining cost is reduced, on the other hand, the installation space of the speed reducer can be effectively reduced, and installation is convenient.

    本发明公开了一种绞车用齿轮箱换挡装置,包括减速箱体、换挡齿轮组、换挡操纵机构和锁挡机构,换挡操纵机构具有设置在减速箱体顶部的手柄、传动组件和拨叉组件,拨叉组件设置在动力组件的动力输出端;手柄自其安装孔分为第一段和第二段,靠近安装孔处的手柄上设置有锁紧板,锁挡机构设置在减速箱体的顶部,其具有与锁紧孔配合的锁紧头,顶板上设置有用于对锁紧头限位的导向件。本发明将手柄和锁挡机构设置在减速箱体上方,外力可通过传动组件传递给减速箱体内的拨叉组件,通过拨叉组件拨动换挡齿轮轴向移动进而实现换挡,结构简单,降低加工成本,另一方面可有效减小减速器的安装空间,便于安装。
