The invention relates to the technical field of crawler-type operating vehicles, in particular to a vertical lifting device for a crawler-type operating vehicle, which comprises two cross beams and a vehicle body, rotating shafts are rotatably mounted on the cross beams, rotating seats are fixedly mounted on the rotating shafts, and supporting arms are mounted on the rotating seats through mounting seats. A telescopic air cylinder is rotatably mounted on the mounting seat, a base plate is mounted at one end of the supporting arm through a fixing seat, a connecting seat is fixedly mounted in the middle of the supporting arm, a semicircular sector gear is fixedly mounted on a rotating seat, a rotating shaft is rotatably mounted on the cross beam, and a straight gear is fixedly connected to the rotating shaft in a sleeving manner. Through mutual cooperation of the rotating shaft, the rotating seat, the sector gear, the rotating shaft and the straight gear, the contact point between the base plate and soil is changed, the contact point between the base plate and the ground does not need to be changed by adjusting the position of a vehicle, operation is convenient, trouble and labor are saved, and the practicability of the device is effectively improved.

    本发明涉及履带式作业车技术领域,尤其涉及一种用于履带式作业车的垂直升降装置,包括两根横梁和车体,所述横梁上转动安装有转动轴,所述转动轴上固定安装有转动座,所述转动座上通过安装座安装有支撑臂,所述安装座上转动安装有伸缩气缸,所述支撑臂的一端通过固定座安装有垫板,所述支撑臂的中间部位固定安装有连接座,所述转动座上固定安装有半圆形的扇形齿轮,所述横梁上转动安装有旋转轴,所述旋转轴上固定套接有直齿轮。本发明通过转动轴、转动座、扇形齿轮、旋转轴和直齿轮的相互配合,来改变垫板与土壤的接触点,无需通过调节车辆的位置来改变与地面之间的接触点,操作方便,省事省力,有效的提高装置的实用性。
