Abstract
The invention discloses a heavy type jack which comprises a positioning seat. A driving part is arranged on the positioning seat and fixedly connected with a supporting part, a first driving rod and a second driving rod are arranged on the driving part, a supporting column is telescopically arranged on the top of the supporting part, the first driving rod and the second driving rod are on one straight line and are perpendicular to the supporting column, and the diameter of the supporting column is not smaller than 10 cm. According to the heavy type jack, the independent driving part and the supporting part are arranged on a jack body, the two driving rods used for driving are arranged on the driving part, the supporting column with the large radius is arranged on the supporting part, and thus the hoisting weight of the jack is greatly increased.
Description
Technical field
The present invention relates to a kind of jack, or rather, is a kind of heavy jack.
Background technology
Jack is the simplest weight-lifting equipment of a kind of lifting highly little (being less than 1m), lifts part as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw with rigidity top.
The jack lifting weight generally used at present is little, and the lifting for some heavy-duty machineries is a bit unable to do what one wishes.
Summary of the invention
The present invention mainly solves the technical matters existing for prior art, thus provides a kind of heavy jack with larger load-carrying ability.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of heavy jack, comprise a positioning base, described positioning base is provided with a drive division, described drive division is fixedly connected with a support portion, described drive division is provided with one first drive spindle and one second drive spindle, and the top telescopically of described support portion is provided with a pillar stiffener.
As preferred embodiment of the present invention, the first described drive spindle and the second drive spindle are point-blank, and perpendicular with described pillar stiffener.
As preferred embodiment of the present invention, the diameter of described pillar stiffener is not less than 10 centimetres.
Because heavy jack of the present invention arranges independently drive division and support portion on jack body, drive division is provided with two drive spindles for driving, and be provided with the pillar stiffener with relatively large radius in support portion, thus substantially increase the lifting weight of jack.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of heavy jack of the present invention;
Fig. 2 is the perspective view of the heavy jack in Fig. 1, is now another visual angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of heavy jack with larger load-carrying ability.
As shown in Figure 1 and Figure 2, a kind of heavy jack 1, comprise a positioning base 2, described positioning base 2 is provided with a drive division 31, described drive division 31 is fixedly connected with a support portion 32, described drive division 31 is provided with one first drive spindle 41 and one second drive spindle 42, and the top telescopically of described support portion 32 is provided with a pillar stiffener 5.
As shown in Figure 1 and Figure 2, the first described drive spindle 41 and the second drive spindle 42 are point-blank, and perpendicular with described pillar stiffener 5.
As shown in Figure 1 and Figure 2, the diameter of described pillar stiffener 5 is not less than 10 centimetres.
The heavy jack of this invention arranges independently drive division and support portion on jack body, and drive division is provided with two drive spindles for driving, and is provided with the pillar stiffener with relatively large radius in support portion, thus substantially increases the lifting weight of jack.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
