Abstract
The utility model discloses a hydraulic lifting system of an externally-arranged jacking cylinder. An oil cylinder inner side support and an oil cylinder outer side support are arranged on an outer side face of the left side and an outer side face of the right side of a vehicle frame of the system, two lifting oil cylinders are arranged on the support on the left side and the support on the right side respectively, and end portions of piston rods of the lifting oil cylinders are connected onto the bottom of a vehicle compartment through pin shafts. When the vehicle compartment is lifted, the hydraulic lifting system can well solve the problem that in the process of vehicle lifting, the center of gravity of the vehicle compartment is unstable due to the fact that a distance between the two lifting oil cylinders is big.
Description
Technical field
The utility model relates to a kind of external hydraulic lifting system of taking blame for others, and belongs to the hydraulic lifting system field.
Background technology
Existing common hydraulic lifting system mostly is oil cylinder and is installed on the vehicle frame inboard because the restriction of vehicle frame inner space, two oil cylinders to open span generally smaller, easily produce the strong point shakiness during lifting, vehicle body easily tilted when goods was heavier, and is dangerous.
The utility model content
Utility model purpose: the utility model proposes a kind of external hydraulic lifting system of taking blame for others, the phenomenon of crank in the time of can solving the compartment lifting.
Technical scheme: the technical solution adopted in the utility model is a kind of external hydraulic lifting system of taking blame for others, and comprises two inboard bearings of oil cylinder that are installed on vehicle frame the right and left lateral surface respectively, and the inboard bearing of each oil cylinder has also connected an oil cylinder outside bearing.The right and left of vehicle frame respectively has an elevating ram, and elevating ram is installed on inboard bearing of oil cylinder and the oil cylinder outside cylinder support that bearing was combined into, and the piston rod end of elevating ram is connected with the bottom, compartment by bearing pin.
During work, enter hydraulic ram inside, make the hydraulic ram lifting by high pressure oil because the spacing of two elevating rams is bigger, can be fine the problem of compartment crank during the solution vehicle lifting.
Beneficial effect: the utility model is simple and reasonable, and is easy for installation, the phenomenon of crank in the time of solving the compartment lifting well.
