The invention relates to the technical field of hydraulic tailboard lifting arm structures, in particular to a hydraulic tailboard lifting arm structure of a truck, which comprises a truck box body, a tailboard turnover device, a tailgate turnover device, a tailgate and a transverse plate, the tailboard turnover device is arranged at the bottom of the truck box body, one end of the tailboard turnover device is connected with the tailgate turnover device, and the tailgate turnover device is connected with the tailgate. A transverse plate is arranged on the tail plate turnover device; if the tail door needs to be placed on the ground, the hydraulic jack pulls the driven shaft through the first shaft sleeve, the driven shaft enables the shaft sleeve to turn over through the matching effect of the bearing and the clamping plate, meanwhile, the hydraulic jack deflects under the matching effect of the guide column and the bearing, the shaft sleeve drives the driving shaft to rotate, and the driving shaft rotates to enable the two supporting rods to rotate. One end of the supporting rod rotates to be parallel to the ground, so that the tail door overturning device makes contact with the ground, the tail door is placed on the ground, a worker can open the tail door more conveniently and rapidly according to actual conditions during unloading and loading, and the working efficiency of the worker is improved.
本发明涉及液压尾板举升臂结构技术领域,具体为一种载货汽车液压尾板举升臂结构,包括车箱体、尾板翻转装置、尾门翻转装置、尾门、横板,车箱体底部设置尾板翻转装置,尾板翻转装置一端连接尾门翻转装置,尾门翻转装置连接尾门,尾板翻转装置上设置横板;如果需要将尾门放置在地面,液压顶通过轴套一拉动从动轴,从动轴通过轴承与夹板配合作用使轴套翻转,同时液压顶在导柱与轴承的配合下位置发生偏转,轴套带动主动轴转动,主动轴的转动使两组支撑杆转动,支撑杆一端转动至与地面平行,从而使尾门翻转装置与地面接触,实现尾门放置在地面上,使工人在卸货和装货时,可根据实际情况,更加方便和快速打开尾门,提高了工人的工作效率。
