The described end, adjusts the cylinder mouth place of jack to be provided with monaural plate, the outside of described base is provided with three groups of otic placodes, wherein first group of otic placode and the described end, adjust one end of single pole hinged, second group of otic placode and the described end, adjust the monaural plate at jack cylinder mouth place hinged, and the 3rd group of otic placode and the described end adjust the cylinder bottom of jack hinged.
The described end, adjusts single pole to be formed by the direct blanking of steel plate, and the described end adjusts two bar to comprise two pieces otic placode, is provided with clamping plate between two pieces otic placode;
The described end, adjusts the two ends of single pole and the described end to adjust the two ends of two bar to be respectively equipped with fraising, and wherein the fraising of the two one end be hinged departs from respective longitudinal centre line respectively, and respective longitudinal centre line place is located in the fraising of the other end respectively.
Hydraulic support of the present invention, its preferably detailed description of the invention be:
This support is provided with above-mentioned hydraulic support outer bottom regulating mechanism.
Specific embodiment:
As shown in Fig. 1 a, 1b, the end, adjusts single pole 2 to be formed by the direct blanking of steel plate, selected steel plate thickness adjusts " the flat youngster " of jack piston rod thick consistent (if inconsistent also passable the end of with, but will adjust on two bar the end of at and weld pasting board to adjust thickness), the perforate of single pole two ends is adjusted at the end, and two hole arranged off-centre.
As shown in Fig. 2 a, 2b, two bar 3 is adjusted by otic placode 5(quantity 2 in the end) and clamping plate 6 be welded, otic placode 5 is except thickness is thin, and other sizes all adjust single pole (Fig. 1) consistent the end of with.The installation that span (i.e. the thickness of clamping plate 2) between two pieces otic placode 5 should ensure to adjust single pole and the end to adjust in the end piston rod of jack can be suitable is in it.
As shown in Figure 3, the end, adjusts jack 4 to be conventional outer feed liquor form, near its cylinder mouth, weld monaural plate 7.The end, adjusts the selection of jack cylinder diameter with reference to the concrete working resistance of support and weight, should ensure that it has enough tune frame abilities.
As shown in Fig. 4 a, 4b, have three groups of otic placodes in the outside weldings of base 1, first group of otic placode 8 adjusts single pole 2(Fig. 1 the end of with) hinged; Second group of otic placode 9 adjusts the monaural plate 7(Fig. 3 at jack 7 cylinder mouth place the end of with) hinged; 3rd group of otic placode 10 adjusts the cylinder bottom of jack 4 hinged the end of with.
As shown in Fig. 5 a, Fig. 5 b, this assembling drawing is the original state of end regulating mechanism.As the above-mentioned elaboration about such as Fig. 4, a hinge of single pole 2 is adjusted at first group of otic placode 8 hinged end of base 1 foremost, the monaural plate 7 at tune jack 4 cylinder mouth place, the hinged end of second group of otic placode 9 in the middle of base 1, the cylinder bottom of jack 4 is adjusted at the 3rd group of otic placode 10 hinged end at base 1 rear portion; The end, adjusts two bar 3 to adjust another hinge of single pole 2 and the end to adjust the piston rod of jack 4 hinged the end of with respectively.
Original state, the end, adjusts jack 4 piston rod to regain, and end tune single pole 2, the end adjust two bar 3 to regain; Jack 4 is adjusted at the end, single pole 2 is adjusted at the end, the end adjusts two bar 3 now all parallel with base 1, designing that jack 4 is adjusted at the end, single pole 2 is adjusted at the end, end tune pair bar 3 time, should ensure that three can be properly mounted between two adjacent bracket bases at this moment.
The end, adjusts jack 4 to be hinged fixing owing to there being two points, and therefore this jack cylinder body is in stationary state (piston rod can free-extension) all the time.
The end adjusts single pole 2, the end adjusts two pin joints of two bar 3 be eccentric design, therefore when the end adjusts the piston rod of jack 4 to stretch out, and can ensure that the end adjusts single pole 2 and the end to adjust the pin joint of pair bar 3 can be protruding.
As shown in Figure 6, the cavity of resorption feed liquor of jack 4 is adjusted at the end, the end adjust single pole 2 and the end adjusts the pin joint of pair bar 3 pushed outwards go out, withstand on adjacent frame base, when support generation deflection, play tuningout effect.As for the size of offset, need control when specific design.
As shown in Figure 7, hydraulic support of the present invention, comprise base 1, single pole 2 is adjusted at the end, two bar 3 is adjusted at the end, jack 4 is adjusted at the end and connect bearing pin etc. accordingly, as previously mentioned, these four kinds of component constitute the core of outer bottom regulating mechanism hydraulic support of the present invention.
In practical application, for making this outer bottom regulating mechanism can adapt to left and right work plane, when design of Hydraulic System, can as required by the operation or neighboring frame-operated of this mechanism design cost frame.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
