Abstract
The utility model discloses a hand operated hydraulic forklift with an oil cylinder piston rod limiting device. The hand operated hydraulic forklift comprises a hydraulic cylinder (1) of the hand operated hydraulic forklift and further comprises the oil cylinder piston rod limiting device. The oil cylinder piston rod limiting device is composed of an oil pipe (2) and an oil tank (3). An oil inlet is formed in the oil tank (3), an oil outlet (1-1) is formed in one end of the hydraulic cylinder (1), and the oil outlet (1-1) is communicated with an oil inlet of the oil tank (3) through the oil pipe (2). The hand operated hydraulic forklift with the oil cylinder piston rod limiting device has the advantages that due to the fact that the hand operated hydraulic forklift is improved based on an existing hand operated hydraulic forklift, workers can operate conveniently, the service life of the cylinder is guaranteed, and the working efficiency is improved.
Description
Technical field
The utility model relates to the fork truck field, is specifically related to a kind of hand operated transport with the cylinder piston rod inhibiting device.
Background technology
At present, existing hand operated transport is when handling goods, need to piston rod be stretched out or shrink by the regulator solution compressing cylinder, then goods is risen or decline by the chain-driving crotch, yet stretching out at piston rod needs in the process to carry out spacing to piston rod, at present all be that vehicle frame entablatrance at hand operated transport is equipped with Limit screw, when arriving the Limit screw position, piston rod then stops to rise, but the staff is in the operation engineering, when even piston rod arrives limit point, still oil cylinder is operated, easy like this oil cylinder and piston rod are caused damage, shorten the service life of oil cylinder.
Summary of the invention
The purpose of this utility model be exactly for present existing hand operated transport when the handling goods, need to piston rod be stretched out or shrink by the regulator solution compressing cylinder, then goods is risen or decline by the chain-driving crotch, yet stretching out at piston rod needs in the process to carry out spacing to piston rod, at present all be that vehicle frame entablatrance at hand operated transport is equipped with Limit screw, when arriving the Limit screw position, piston rod then stops to rise, but the staff is in the operation engineering, when even piston rod arrives limit point, still oil cylinder is operated, easy like this oil cylinder and piston rod are caused damage, the deficiency that shortens the service life of oil cylinder, and a kind of hand operated transport with the cylinder piston rod inhibiting device is provided.
The utility model comprises the hydraulic ram of hand operated transport, it also has the cylinder piston rod inhibiting device, and the cylinder piston rod inhibiting device is comprised of oil pipe and fuel tank, has oil inlet on the fuel tank, hydraulic ram one end has oil outlet, and oil outlet communicates with the oil inlet of fuel tank by oil pipe.
The utility model advantage is: this device improves at existing hand operated transport, has made things convenient for staff's operation, has guaranteed the service life of oil cylinder, increases work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises the hydraulic ram 1 of hand operated transport, it also has the cylinder piston rod inhibiting device, the cylinder piston rod inhibiting device is comprised of oil pipe 2 and fuel tank 3, have oil inlet on the fuel tank 3, hydraulic ram 1 one ends have oil outlet 1-1, and oil outlet 1-1 communicates by the oil inlet of oil pipe 2 with fuel tank 3.
Principle of work: in hydraulic ram 1 working process, 4(sees Fig. 1 when piston rod) in uphill process, when piston rod 4 bottoms are higher than on the hydraulic ram 1 oil outlet 1-1 height, this moment, hydraulic ram 1 interior hydraulic oil was entered in the fuel tank 3 by oil pipe 2 from oil outlet 1-1, hydraulic oil in the hydraulic ram 1 is not enough at this moment, then piston rod 4 stops to rise, and reaches spacing purpose.
Claims (1)
