The described end, transfer the cylinder mouth place of jack to be provided with the 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, transfer an end of single pole hinged, second group of otic placode and the described end, transfer the monaural plate at jack cylinder mouth place hinged, and the 3rd group of otic placode and the described end transfer the cylinder bottom of jack hinged.
The described end, transfer single pole to be formed by the direct blanking of steel plate, and the described end transfers two bars to comprise two otic placodes, is provided with clamping plate between two otic placodes;
The described end, transfer the two ends of single pole and the described end to transfer the two ends of two bars to be respectively equipped with fraising, and wherein the fraising of the two end that is hinged departs from respectively longitudinal centre line separately, and longitudinal centre line place separately is located at respectively in the fraising of the other end.
Hydraulic support of the present invention, its better specific embodiment is:
This support is provided with above-mentioned hydraulic support outer bottom regulating mechanism.
Specific embodiment:
Shown in Fig. 1 a, 1b, it is to be formed by the direct blanking of steel plate that single pole 2 is transferred at the end, selected steel plate thickness transfers " the flat youngster " of jack piston rod thick consistent (if inconsistent also passable the end of with, but will transfer the end of at two bar welding pasting boards to adjust thickness), single pole two ends perforate is transferred at the end, and two hole arranged off-centre.
Shown in Fig. 2 a, 2b, two bars 3 are transferred by 2 of otic placode 5(quantity in the end) and clamping plate 6 be welded, otic placode 5 is except thin thickness, other sizes are all consistent with end accent single pole (Fig. 1).Span (being the thickness of clamping plate 2) between two otic placodes 5 should guarantee that the end transfers single pole and the end to transfer installation that the piston rod of jack can be suitable in it.
As shown in Figure 3, it is conventional outer feed liquor form that jack 4 is transferred at the end, near welding monaural plate 7 its cylinder mouth.The end, transfer the selection of jack cylinder diameter with reference to support concrete working resistance and weight, to guarantee that it has enough accent frame abilities.
Shown in Fig. 4 a, 4b, in the outside weldings of base 1 three groups of otic placodes are arranged, first group of otic placode 8 transferred single pole 2(Fig. 1 the end of with) hinged; Second group of otic placode 9 transferred the monaural plate 7(Fig. 3 at jack 7 cylinder mouth places the end of with) hinged; The 3rd group of otic placode 10 transfers the cylinder bottom of jack 4 hinged the end of with.
Shown in Fig. 5 a, Fig. 5 b, this assembling drawing is the original state of end regulating mechanism.As above-mentioned about the elaboration such as Fig. 4, a hinge of single pole 2 is transferred at the 8 hinged ends of base 1 top first group of otic placode, the monaural plate 7 at jack 4 cylinder mouth places is transferred at the 9 hinged ends of second group of otic placode in the middle of the base 1, and the cylinder bottom of jack 4 is transferred at the 10 hinged ends of the 3rd group of otic placode at base 1 rear portion; The end, transfer two bars 3 to transfer another hinge of single pole 2 and the end to transfer the piston rod of jack 4 hinged the end of with respectively.
Original state, the end, transfer jack 4 piston rods to regain, and the end, transfer single pole 2, the end to transfer two bars 3 to regain; The end, transfer jack 4, the end to transfer single pole 2, the end to transfer two bars all parallel with base 13 this moments, transfers jack 4, the end to transfer single pole 2, the end when transferring two bar 3 at the design end, should guarantee that the three can be properly mounted between the two adjacent bracket bases at this moment.
Jack 4 is transferred at the end because to have two points to be hinged fixing, so this jack cylinder body is in stationary state (piston rod can free-extension) all the time.
It is the off-centre design that two pin joints of single pole 2, the two bars 3 of end accent are transferred at the end, so when the end transfers the piston rod of jack 4 to stretch out, can guarantee that end accent single pole 2 and the pin joint of the two bars 3 of end accent can be protruding.
As shown in Figure 6, the cavity of resorption feed liquor of jack 4 is transferred at the end, and the end transfers single pole 2 and the end to transfer that the pin joint of two bars 3 is pushed outwards to be gone out, and withstands on the adjacent frame base, when support generation deflection, plays the tuningout effect.As for the size of offset, need when specific design, to control.
As shown in Figure 7, hydraulic support of the present invention comprises that base 1, the end transfer single pole 2, the end to transfer two bars 3, the end to transfer jack 4 and the corresponding bearing pin etc. that connects, and as previously mentioned, these four kinds of component have consisted of the core of outer bottom regulating mechanism hydraulic support of the present invention.
In the practical application, can adapt to left and right sides work plane for making this outer bottom regulating mechanism, when design of Hydraulic System, can be as required with this mechanism design cost frame operation or neighboring frame-operated.
The above; only for the better specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation 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.
