Description
Technical field
The present invention relates to technical field of hydraulic oil cylinder, especially a kind of water proof anti-soil hydraulic headstock gear.
Background technology
In recent years, hydraulic headstock gear has obtained increasingly being widely applied in hydraulic engineering, so to hydraulic jack
Requiring it is also more and more higher, it is also such that water proof anti-soil requires.Gate in water conservancy is with hydraulic headstock gear by gate lifting eye
Hang what head was connected, so the waterproof sealing hanging head is particularly important；The switch of gate by piston rod extension and contraction control, so
The antifouling of piston rod exposed parts is also critically important.Hydraulic jack is by upper and lower cover, cylinder body, piston, piston rod, hangs first-class
Several big parts form.Piston rod uses threaded with hanging head, and the waterproof of connecting portion certainly will be critically important, because water once enters
Hanging a junction, it will corrosion screw thread, make screw thread get rusty, reduction of service life, piston rod chromium plating part can be because of the water that soaks for a long time
Infiltration body of rod nexine gets rusty and produces chromium peeling conditions, especially plates ceramic cylinder rod；In the situation that work condition environment is severe
In lower piston rod telescopic process, scraping dirt circle scraping dirt can not also influence whether the operation of hydraulic headstock gear thus directly influence in time
The switch of gate.Traditional waterproof sealing scheme, piston rod chromium plating part is not effectively protected measure, and hangs head and work
At the holding screw that stopper rod connects, also the most long-time immersion is got rusty.
Summary of the invention
The technical problem to be solved in the present invention is: can be because of length in order to solve the piston rod chromium plating part of conventional hydraulic headstock gear
Phase immersion water penetration body of rod nexine gets rusty and produces chromium peeling conditions, and in the case of work condition environment is severe, piston rod stretches
During scraping dirt circle scraping dirt can not also influence whether the operation of hydraulic headstock gear in time, and hang the tightening that head is connected with piston rod
Also easily soak for a long time at screw the problem got rusty, it is provided that one water proof anti-soil hydraulic headstock gear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water proof anti-soil hydraulic headstock gear, including on
Lid, lower cover, cylinder body, piston, piston rod and hang head, described upper cover and lower cover are connected to the two ends of cylinder body, and described piston sets
Putting in cylinder body, one end of piston rod is connected with piston, and the other end of piston rod passes lower cover and is connected with hanging head thread, described work
Stopper rod and hang and be provided with sealing ring between head, described in hang the periphery of head and be provided with along hanging the screwed hole that head radially extends, described screw thread
Being provided with trip bolt in hole, described trip bolt holds out against piston rod, is provided with packing ring and hexagonal socket head plug in described screwed hole, described
Packing ring and hexagonal socket head plug are successively set on outside trip bolt, and the exposed parts of described piston rod is arranged with scalable dust cover,
The two ends of described dust cover respectively with lower cover and hang head and be connected.Piston rod and hang sealing ring is set between head, and in screwed hole
Jump a queue packing ring and hexagonal socket head plug, prevent water from entering the junction hanging head with piston rod, corrode screw thread, make screw thread get rusty, shorten
In the service life of hydraulic headstock gear, prevent piston rod chromium plating part from producing because long-term immersion water penetration body of rod nexine gets rusty
Chromium peeling conditions；Dust cover makes the exposed parts of piston rod obtain soiling protective, does not also interfere with in the case of operating mode is severe
Headstock gear properly functioning thus directly influence the switch of gate.
The two ends of described dust cover by anchor ear respectively with lower cover and hang head and be connected, good seal performance and disassembling, assembling and replacing are simple
Single.
Described dust cover is Water-proof and oil-proof, antifouling protective cloth.
The invention has the beneficial effects as follows, the present invention uses and surrounds piston rod outside sealing ring, increases plug screw, make at trip bolt
Piston rod obtains more preferable waterproofing protection, and oil cylinder is played more preferable soiling protective by the dust cover arranged outside piston rod, and tears open
Dress is changed simple, and cost is relatively low, improves work efficiency, makes that hydraulic switch function is safe and reliable, runs smoothly.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is enlarged drawing at A in Fig. 1.
In figure: 1. upper cover, 2. cylinder body, 3. lower cover, 4. piston, 5. piston rod, 6. hang head, 7. sealing ring, 8. trip bolt,
9. packing ring, 10. hexagonal socket head plug, 11. dust covers, 12. anchor ears.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only with
The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
As it is shown in figure 1, a kind of water proof anti-soil hydraulic headstock gear, including upper cover 1, lower cover 3, cylinder body 2, piston 4, piston rod 5
With hang 6, described upper cover 1 and lower cover 3 are connected to the two ends of cylinder body 2, and described piston 4 is arranged in cylinder body 2, piston rod 5
