Abstract
The utility model discloses a superhigh pressure heavy load jack, including high -pressure hydro -cylinder with high -pressure hydro -cylinder complex piston, go up the gland, the piston sets up in high -pressure hydro -cylinder, go up the top of gland setting at high -pressure hydro -cylinder to the connection is between high -pressure hydro -cylinder and piston, the piston bottom is equipped with one at least recess, be equipped with the high -pressure dynamic sealing circle in the recess, be equipped with the guide ring between piston bottom and the hydraulic cylinder inside wall, this guide ring and piston fixed connection, be equipped with first high -pressure static seal circle between the gland and the voltol oil inside wall of cylinder, be equipped with second high pressure static seal circle between gland and the piston. This jack is small, load is big, can bear high pressure hydraulic oil and strike.
Description
Technical field
This utility model is related to a kind of lifting apparatus, more particularly, to a kind of supertension heavy duty jack.
Background technology
It is a lot of that jack is applied when lifting, and traditional hydraulic jack pressure is in below 70mpa, extra heavy in jacking
During load, lift cylinder quantity is more, need to set up a lot of temporary facilities, build these temporary facilities waste a lot of materials and
Manually.And severe in some execution conditions, in the case of narrow space, large-tonnage oil cylinder is excessive due to volume, it is difficult to install
With.
Content of the invention
Part in order to overcome the above-mentioned deficiencies of the prior art, this utility model provides a kind of supertension heavy duty jack, should
Jack small volume, load are big, can bear high pressure liquid force feed impact.
For achieving the above object, this utility model adopts the following technical scheme that a kind of supertension heavy duty jack, including high
Compressing cylinder and the piston with high-voltage oil cylinder cooperation, upper press cover, described piston is arranged in high-voltage oil cylinder, and described upper press cover is arranged on
The top of high-voltage oil cylinder, and be connected between high-voltage oil cylinder and piston, described piston base is provided with least one groove, described recessed
It is provided with high pressure dynamic sealing circle in groove, between described piston base and hydraulic jack medial wall, be provided with guide ring, this guide ring and work
Plug is fixedly connected, and is provided with the first high pressure static sealing ring between described gland and high-voltage oil cylinder inwall, is provided between gland and piston
Two high pressure static sealing rings.
In technique scheme, near the upper end of described gland and piston, it is provided with dust ring.
In technique scheme, described guide ring is copper guide ring.
The beneficial effects of the utility model are: this jack small volume, and load is big, can not bear high high-pressure and hydraulic in space
Oil impact, particularly in the extra heavy load of jacking, usage quantity is few, and the temporary facility set up is few, saves time and manpower, due to
This jack small volume, using even more convenient in the case that some narrow spaces load is big.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of local a in Fig. 1.
Fig. 3 is the enlarged drawing of local b in Fig. 1.
Wherein: 1. high-voltage oil cylinder, 2. piston, 3. upper press cover, 4. guide ring, 5. high pressure dynamic sealing circle, 6. the first high pressure is quiet
Sealing ring, 7. the second high pressure static sealing ring, 8. dust ring.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of supertension heavy duty jack as shown in Figure 1, Figure 2 and Figure 3, joins including high-voltage oil cylinder 1 with high-voltage oil cylinder 1
The piston 2 of conjunction, upper press cover 3, described piston 2 is arranged in high-voltage oil cylinder 1, and described upper press cover 3 is arranged on the top of high-voltage oil cylinder 1
Portion, and be connected between high-voltage oil cylinder 1 and piston 2, described piston 2 bottom is provided with least one groove, is provided with described groove
High pressure dynamic sealing circle 5, is provided with guide ring 4 between described piston 2 bottom and hydraulic jack 1 medial wall, this guide ring 4 and piston 2
It is fixedly connected, be provided with the first high pressure static sealing ring 6 between described gland 3 and high-voltage oil cylinder 1 inwall, be provided between gland 3 and piston 2
Second high pressure static sealing ring 7.Guide ring 4 can play good guide effect, the impact that high pressure dynamic sealing circle 5 presses oil in high pressure liquid
Under, play good sealing effectiveness while this impact can be born.First high pressure static sealing ring 6 and the second high pressure static sealing ring
7 setting is so that this jack has good pressurize ability.
In technique scheme, near described gland 3 and the upper end of piston 2, it is provided with dust ring 8.The energy of dust ring 8
Stop external dust from entering in high-voltage oil cylinder 1, prevent oil cylinder inner wall accelerated wear test.
In technique scheme, described guide ring 4 is copper guide ring, copper guide ring material and high-voltage oil cylinder 1 inwall phase
Softer, prevent high-voltage oil cylinder 1 inwall to be quickly worn.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.
