Abstract
The utility model aims to provide a hydraulic spring cylinder with short stroke, small size and high elastic force. The cylinder comprises a cylinder body, and a cylinder head mounted on the cylinder body; a piston and a piston rod fixed at the central part of the piston are mounted in the cylinder body, and the front end of the piston rod extends out of the cylinder head; dished springs are sleeved on the piston rod; and two adjacent dished springs are mounted in opposite directions. The cylinder has the advantages of simple structure, convenient maintenance, small size and low manufacture cost.
Description
Technical field
The utility model relates to a kind of hydraulic jack, specifically relates to a kind of hydraulic spring grease cup oil cylinder that is applied in the mining equiment.
Background technique
At present, the hydraulic spring grease cup oil cylinder of known use generally uses helical spring to make energy storage unit, need spring to produce in the hydraulic spring grease cup oil cylinder of big elastic force at some, need the helical spring of lengthening overstriking inside, thereby make oil cylinder stroke long, volume is big, the manufacture cost height.
Summary of the invention
The utility model aims to provide the hydraulic spring grease cup oil cylinder that a kind of stroke is short, volume is little, elastic force is big.
The technical solution adopted in the utility model is: a kind of hydraulic spring grease cup oil cylinder comprises cylinder body and is installed in cylinder cap on the cylinder body that piston is installed in the cylinder body and is fixed in the middle of the piston and front end stretches out the piston rod of cylinder cap, upper cover of piston rod has belleville spring.
Above-mentioned upper cover of piston rod has the multi-disc belleville spring, and installs in opposite directions between adjacent two belleville springs.
The utility model is owing to adopt belleville spring to replace helical spring commonly used, and under the condition that produces same elastic force, the stroke that belleville spring needs is short, and volume is little, thereby hydraulic spring grease cup oil cylinder volume is reduced, and manufacture cost reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below, the utility model is described in further detail in conjunction with the accompanying drawings
Fig. 1 shows a kind of hydraulic spring grease cup oil cylinder, comprise cylinder body 1 and be installed in cylinder cap 5 on the cylinder body 1, piston 3 is installed in the cylinder body 1 and is fixed in the middle of the piston 3 and front end stretches out the piston rod 6 of cylinder cap 5, be with multi-disc belleville spring 4 on the piston rod 6, and adjacent two belleville springs 4 are installed in opposite directions.
When hydraulic oil in oil inlet pipe 2 enters cylinder body 1, promote the resistance that piston 3 overcomes belleville spring 4 and travel forward, drive piston rod 6 and protract; When the hydraulic system release, when hydraulic oil refluxed, belleville spring 4 resetted, and piston 3 retreats under the elastic force effect of belleville spring 4, piston rod 6 withdrawals.
Claims (2)
1, a kind of hydraulic spring grease cup oil cylinder comprises cylinder body and is installed in cylinder cap on the cylinder body, piston is installed in the cylinder body and is fixed in the middle of the piston and front end stretches out the piston rod of cylinder cap, it is characterized in that upper cover of piston rod has belleville spring.
2, hydraulic spring grease cup oil cylinder as claimed in claim 1 is characterized in that described upper cover of piston rod has the multi-disc belleville spring, and installs in opposite directions between adjacent two belleville springs.
