The invention relates to a hydraulic lifting device with a cleaning function. The hydraulic lifting device with the cleaning function comprises a bottom plate, a cylinder body, a piston rod and a topplate and further comprises a cleaning mechanism and two supporting mechanisms, each supporting mechanism comprises a lifting assembly, a lifting block, a hinge rod and a supporting plate, the cleaning mechanism comprises a rotating ring, a torsion spring, a fixing ring, a moving ring, a limiting assembly, two sponge blocks, two fixing assemblies, two connecting assemblies and a plurality of firstsprings, each fixing assembly comprises a pressing plate, a pull rod, a pull plate, a limiting block and a second spring. According to the hydraulic lifting device with the cleaning function, throughthe supporting mechanisms, the contact area between the hydraulic lifting device and the ground is increased, the situation that the normal lifting work of the hydraulic lifting device is affected due to fact that the cylinder body sinks the into ground is avoided; and through the cleaning mechanism, the function of cleaning the piston rod is achieved, dust in air is prevented from adhering to the piston rod, the probability that the dust enters the cylinder body is reduced, the situation that the dust is mixed with hydraulic oil, and consequently deterioration of the hydraulic oil is affected is further avoided, and therefore the reliability of the hydraulic lifting device is improved.

    本发明涉及一种具有清洁功能的液压升降装置,包括底板、缸体、活塞杆和顶板,还包括清洁机构和两个支撑机构,支撑机构包括升降组件、升降块、铰接杆和支撑板,清洁机构包括转环、扭转弹簧、固定环、移动环、限位组件、两个海绵块、两个固定组件、两个连接组件和若干第一弹簧,固定组件包括压板、拉杆、拉板、限位块和第二弹簧,该具有清洁功能的液压升降装置通过支撑机构,增加了设备与地面接触面积,避免缸体陷入地面内而影响设备的正常升降工作,通过清洁机构,实现了清洁活塞杆的功能,避免空气中的灰尘粘附在活塞杆上,从而减小了灰尘进入缸体的几率,从而避免灰尘与液压油混合而影响液压油的变质,从而提高了设备的可靠性。
