Description
[technical field]
The utility model relates to the technical field of oil hydraulic cylinder, particularly a kind of technical field of electric lifting/lowering oil hydraulic cylinder.
[background technique]
Electric lift is a kind of jacking equipment using electric energy as power, be mainly used in the fields such as enterprise, chemical industry, municipal administration, electric power, traffic, have convenient mobile, the advantages such as easy left-hand seat, easy and simple to handle, scope is wide, balance is good, adjustable height according to model difference not etc., is widely used in industry installation, overhaul of the equipments etc.Electrohydraulic cylinder belongs to a kind of mechanism common in electric lift, has stable feature accurately, very welcome.But conventional cylinder is easily leakage of oil in use, runs into emergency case as do not solved very well during power-off, ensure safety, very inconvenient, be not well positioned to meet the demand of people.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of electric lifting/lowering oil hydraulic cylinder, and can make to prevent oil hydraulic cylinder from bouncing back by metre filter high pressure oil and solenoid valve, working efficiency is high, good airproof performance, applying flexible, and structure is simple.
For achieving the above object, the utility model proposes a kind of electric lifting/lowering oil hydraulic cylinder, comprise AC motor, cylinder barrel, coupling, gear pump, valve block, piston rod, the lower end of described cylinder barrel is provided with coupling, the upper end of described cylinder barrel is provided with piston rod, described AC motor and cylinder barrel coordinate to be installed, described coupling and gear pump are connected, described piston rod and valve block coordinate to be installed, described valve block is provided with filter, described valve block is provided with solenoid valve, described cylinder barrel is provided with projection.
As preferably, described valve block is provided with droop adjustment screw and pressure regulating screw.
As preferably, described projection is provided with sealing block, described sealing block with project through screw and be fixedly connected with.
As preferably, described piston-rod lower end is provided with seal ring.
As preferably, in described valve block, be provided with relief valve, oil sucting one-way valve, throttling one-way valve.
The beneficial effects of the utility model: the utility model is by being applied in electric hydaulic cylinder apparatus by filter and solenoid valve, hydraulic system can be made more stable, and the oil hydraulic cylinder retraction situation avoiding unexpected power-off to cause, can increase work efficiency, good airproof performance simultaneously, device structure is simple.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
