Abstract
The invention relates to a high-pressure oil supercharger for a hoist cylinder locking device and relates to an auxiliary device of a hydraulic hoist. The high-pressure oil supercharger comprises a medium- and low-pressure cylinder barrel; a rear cover is fixedly connected to the rear end of the medium- and low-pressure cylinder barrel and provided with a rear oil opening; a front cover is disposed within the front end of the medium- and low-pressure cylinder barrel; the front end of the medium- and low-pressure cylinder barrel is provided with a front oil opening; a piston is disposed within the medium- and low-pressure cylinder barrel and connected with a piston rod; the piston rod penetrates the front cover; the front end of the medium- and low-pressure cylinder barrel is connected with a supercharging cylinder barrel; the front end of the piston rod penetrates the supercharging cylinder barrel; the supercharging cylinder barrel is provided with an oil supplement opening; the front end of the supercharging cylinder barrel is a blind end and provided with a high-pressure oil outlet. When high-pressure oil supercharger is in service, low pressure oil is fed from the oil supplement opening into a supercharging cylinder, is supercharged severalfold in a short time to achieve supercharging, and is then discharged from the high-pressure oil outlet. The high-pressure oil supercharger is simple in structure, good in supercharging effect and low in cost.
Description
Technical field
The present invention relates to the supplementary equipment of hydraulic hoist, particularly relate to the pressurized machine that high pressure oil is provided to hoist oil cylinder locking device.
Background technique
Pressurized machine is in fact a kind of hydraulic amplifier, in hydraulic system, if whole system needs low pressure, and local or a certain branch road are when needing high pressure, pressurized machine can be used, the local oil circuit of system or certain executive module is made to obtain high pressure oil than hydraulic pump works pressure height several times (2 ~ 7 times), to meet the needs of partial duty mechanism, and the more expensive high pressure oil pump of price need not be set separately, system still remains on lower pressure operation, so just can reduce energy consumption, minimizing equipment, simplification system.Existing pressurized machine all exists that complex structure, pressurized effect are poor, high in cost of production defect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the high pressure oil pressurized machine of the hoist oil cylinder locking device that a kind of structure is simple, pressurized effect good, cost is low is provided.
The object of the present invention is achieved like this: the high pressure oil pressurized machine of hoist oil cylinder locking device, comprise mesolow cylinder tube, the rear end of mesolow cylinder tube is fixedly connected with bonnet, bonnet is arranged rear hydraulic fluid port, the leading inside of mesolow cylinder tube arranges protecgulum, and the front end of mesolow cylinder tube arranges front hydraulic fluid port, in mesolow cylinder tube, arrange piston, piston connects piston rod, and piston rod is set in protecgulum; The front end of described mesolow cylinder tube connects pressurizing cylinder cylinder barrel, and the front end of piston rod is set in pressurizing cylinder cylinder barrel, pressurizing cylinder cylinder barrel is arranged repairing mouth, and the front end of pressurizing cylinder cylinder barrel is cecum, and the front end of pressurizing cylinder cylinder barrel arranges high pressure oil outlet.
During work, in pressurizing cylinder, input low pressure oil from repairing mouth, make its supercharging within a short period of time several times reach pressurization, export from high pressure oil outlet.Principle is that the in-oil cylinder piston rod of mesolow stretches out the delivery pressure of pressurizing cylinder is increased, because pressure is constant, when compression area from large to small time, then pressure also with to vary in size and the principle that changes, thus can reach pressure result pressure being brought up to decades of times.Structure of the present invention is simple, pressurized effect good, cost is low.
In order to make sealing better, to improve pressurized effect, the first seal arrangement is set between mesolow cylinder tube and piston.
The same, the second seal arrangement is set between protecgulum mesolow cylinder tube and protecgulum.
The same, the 3rd seal arrangement is set between piston and piston rod.
