The specific embodiment
Through embodiment the present invention is done further explain below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; In the present embodiment; It comprises on first on the connecting rod 1, second connecting rod 2, first lower link 3, second lower link 4, gusset 5 and lifts end jack and form; On first on the connecting rod 1 and second connecting rod 2 upper ends hinged through bearing pin, the lower end and first lower link, 3 upper ends of connecting rod 1 are hinged on first, the end and second lower link, 4 upper ends of connecting rod 2 are hinged on second; First lower link 3 and second lower link 4 are articulated on the gusset 5; Connecting rod 2 on the connecting rod 1, second on first, first lower link 3 and, the structure that constitutes of second lower link 4 and gusset 5 is located at the crotch portion top of hydraulic support foundation 7, this structure is positioned at along the plane of base width and is symmetrical set with the axial bisector plane of crotch, on first on the connecting rod 1 and second jointed shaft of connecting rod 2 be located on the base 7; The jointed shaft place of the connecting rod 1 and first lower link 3 is hinged with an end of lifting end jack 6 on first; This other end of lifting end jack 6 is articulated on the otic placode of base 6, and the jointed shaft place of the connecting rod 2 and second lower link 4 is hinged with the end that another lifts end jack 61 on second, this another lift end jack 61 the other end be articulated on the otic placode of base 7.Connecting rod 1 is made up of two plate welding on first; Connecting rod 2 is made up of the welding of two plates on second, and connecting rod 2 upper ends are positioned at two plate inboards of connecting rod 1 on first on second, and first lower link 3 comprises two plates; The upper end of two plates of first lower link 3 is positioned at two plate inboards of connecting rod 1 on first; Second lower link 4 comprises two plates, and the upper end of two plates of second lower link 4 is positioned at two plate outsides of connecting rod 2 on second, and two plate lower ends of first lower link 3 and second lower link 4 are positioned at the outside of gusset 5; Form cross structure like this, can improve this structure bearing capacity.Because connecting rod 2 on the connecting rod 1, second on first, first lower link 3 and, the structure that constitutes of second lower link 4 and gusset 5 is symmetrical set with the axial bisector plane of crotch, therefore under two effects of lifting end jack, gusset 5 pumps, realization is lifted at the end.
Middle part at connecting rod on first 1 is welded with the casing 11 that is made up of steel plate between its two plates; Middle part at connecting rod on second 2 is welded with the casing 21 that is made up of steel plate between its two plates; The casing that is welded through steel plate is connected two plates of connecting rod on the connecting rod and second on first, can improve its supporting capacity.
Gusset 5 is inverted U-shaped, and two vertical branches of this inverted U-shaped gusset 5 match with hydraulic support foundation 7 crotch portions inboard vertical guide 71, by this vertical guide gusset are realized guiding, position-limiting action.
Gusset 5 middle part downsides are provided with the projective structure that is circular arc, have increased when lifting the end itself and the supporting capacity that contacts of push rod (base plate).
The present invention reasonably arranges bottom raising mechanism in the limited space of base, make girdle with the space expansion as far as possible of support, and can realize lifting end function better, avoids girdle can not lift the problem at the end.
