The invention provides a reinforced hoisting machinery connecting shaft, and relates to the technical field of cranes. The reinforced hoisting machinery connecting shaft comprises a bottom plate, thetop of the bottom plate is fixedly connected with a workbench, the top of the workbench is provided with a fixing mechanism, the fixing mechanism comprises two fixing supports, the bottoms of the twofixing supports are both fixedly connected with the top of the workbench, and through grooves are formed in the opposite sides of the two fixing supports. A fixing mechanism is additionally arranged in the connecting shaft for hoisting machinery, when a machine is not used, racks can be pulled upwards, due to the fact that the racks are movably connected with the inner surfaces of the through grooves, the racks are pulled upwards to move forwards until the two racks get closer and closer to the outer surface of an automatic telescopic rod and a fixed half ring is in contact with the automatictelescopic rod, the racks are released, grooves in the bottoms of the racks are connected with clamping columns at the bottoms in a clamped mode, the automatic telescopic rod is fixed, a connecting shaft device of the crane is prevented from moving, and the safety of the crane is improved.

    本发明提供加固式起重机械连接轴,涉及起重机技术领域,包括底板,底板的顶部固定连接有工作台,工作台的顶部设置有固定机构,固定机构包括固定支架,固定支架设置有两个,另个固定支架的底部均与工作台的顶部固定连接,两个固定支架相对的一侧均开设有通槽,通过在起重机机械用连接轴的内部增加了固定机构,机器不使用时,可以通过向上拉动齿条,由于齿条与通槽的内表面活动连接,向上拉动齿条向前移动,直至两个齿条距离自动伸缩杆的外表面越来越近,直至固定半圈与自动伸缩杆接触后,放开齿条,齿条底部的凹槽与底部卡柱卡合连接,实现对自动伸缩杆的固定作用,避免起重机的连接轴装置移位,提高了该起重机的安全性。
