Abstract
The utility model relates to a rear cover of a large-tonnage engineering hydraulic jack, which is a reinforced rear cover device of a large-tonnage jack. The rear cover comprises an outer rear cover and an inner rear cover; the outer rear cover is positioned at one end of a jack body; the bottom of the outer rear cover adopts a circular structure, and the outer rear cover is 110 mm to 130 mm in thickness; the outer rear cover and the inner rear cover are connected by a slipknot; the inner rear cover is connected with a rod piston and a rod; the outer rear cover is made of alloy carbon structural steel. The thickened rear cover of the large-tonnage engineering hydraulic jack improves the thrust output support of the large-tonnage jack greatly, prolongs the service life of the large-tonnage jack, and reduces or avoids the overhaul or scrapping of the large-tonnage jack; meanwhile, the connection manner of the outer rear cover and the inner rear cover is changed from the original fixed connection to the slipknot connection, so that the capability of maintaining the large-tonnage jack by workers is facilitated.
Description
Technical field
The utility model belongs to large-tonnage engineering hydraulic jack technical field, especially a kind of large-tonnage engineering hydraulic jack bonnet.
Background technology
The rear tegmental wall of the large-tonnage jack of prior art is thin, the thickness of outer rear cover is only 60mm left and right, in use procedure, easily damages, and built on the sand, in the service life of easily reducing large-tonnage jack, when serious, can cause large-tonnage jack to need overhaul or cause scrapping.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of large-tonnage engineering hydraulic jack bonnet of thickening is provided, and extends the service life of large-tonnage jack, reduces or avoids large-tonnage jack overhaul or scrap.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of large-tonnage engineering hydraulic jack bonnet, formed by outer rear cover and interior bonnet, described outer rear cover is positioned at one end of jack body, and the bottom of outer rear cover is circular configuration, it is characterized in that: the thickness of outer rear cover is 110mm-130mm, described outer rear cover and interior bonnet adopt knot that can be undone by a pull connection mode, and described interior bonnet connects a bar piston, and a described bar piston connects a bar.
Further, described outer rear cover adopts alloy carbon structural steels.
Advantage of the present utility model and good effect are:
In such scheme, the large-tonnage engineering hydraulic jack bonnet of thickening, has extended the service life of large-tonnage jack, reduces or avoids large-tonnage jack overhaul or scrap; Simultaneously large bonnet and interior bonnet adopt knot that can be undone by a pull connection mode, can facilitate staff to keep in repair jack.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1, outer rear cover; 2, interior bonnet.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of large-tonnage engineering hydraulic jack bonnet, as shown in Figure 1: formed by outer rear cover 1 and interior bonnet 2, described outer rear cover 1 is positioned at one end of jack body, and the bottom of outer rear cover 1 is circular configuration, it is characterized in that: the thickness of outer rear cover 1 is 110mm-130mm, described outer rear cover 1 adopts knot that can be undone by a pull connection mode with interior bonnet 2, and described interior bonnet 2 connects a bar piston, and a described bar piston connects a bar; Described outer rear cover 1 adopts alloy carbon structural steels; Described outer rear cover can adopt squared design or triangular design in an embodiment, and the shape of outer rear cover can be different from the shape of interior bonnet, adopts squared design or triangular design can increase the steadiness of jack.
What the utility model adopted is lid arrangement after a kind of heavier-duty large-tonnage jack, and it has ensured the thrust output of large-tonnage jack.Formed by interior bonnet and outer rear cover.According to different thrust outputs, the thickness of outer rear cover is increased to size more than present 110mm by original 60mm.Material changes alloy carbon structural steels into by original common straightcarbon steel, has improved so greatly the thrust output of large-tonnage jack and has supported, and has extended the service life of large-tonnage jack, reduces or avoids large-tonnage jack overhaul or scrap; The connection structure of interior bonnet and outer rear cover also changes knot that can be undone by a pull movable connection structure into by original being fixedly connected with, and has facilitated the ability of maintenance of staff to large-tonnage jack.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model is not limited to the embodiment described in detailed description of the invention; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
