The invention relates to the technical field of freight equipment, and discloses a ship piling clutch hydraulic car comprising a base, a pallet fork is movably connected to the upper surface of the left side of the base, a handle rod is movably connected to the upper surface of the right side of the base, and a liquid pressing device located below the handle rod is fixedly connected to the upper surface of the right side of the base. A hydraulic cylinder is fixedly connected to the upper surface of the middle of the base. By arranging a no-load descending mechanism, when the hydraulic car is used and a user forgets to move the pallet fork to the lowest position, a movable rod overcomes the gravity of the no-load pallet fork to move upwards under the effect of the upward elastic force of a spring on the movable rod, and therefore an opening in the lower end of a liquid discharge pipe which is staggered and closed due to the downward movement of the movable rod is opened. Under the effect of the gravity of the pallet fork and a piston rod themselves, hydraulic oil in a hydraulic cavity is continuously discharged into a liquid storage cavity through the liquid discharge pipe, and therefore the piston rod can drive the pallet fork to slowly descend, and the pallet fork can automatically descend to the lowest point after being unloaded for a period of time.
本发明涉及货运设备技术领域,且公开了一种船舶打桩离合器液压轿车,包括底座,所述底座左侧的上表面活动连接有货叉,所述底座右侧的上表面活动连接有把杆,所述底座右侧的上表面固定连接有位于把杆下方的压液器,所述底座中部的上表面固定连接有液压缸。本发明通过设置空载下降机构,使得在使用完液压车但忘记将货叉将至最低时,在弹簧对活动杆向上弹力的作用下,使得活动杆克服空载货叉的重力向上移动,从而使得被活动杆向下移动而错位封闭的排液管下端开口被打开,在货叉以及活塞杆自身重力的作用下,使得液压腔内液压油不断通过排液管向储液腔内排液,使得活塞杆能带动货叉缓慢下降,从而使得货叉在空载一端时间后自动降至最低点。
