The specific embodiment

Embodiment:

A kind of hydaulic lift platform, as shown in drawings, comprise base 15, bearing surface 1, hydraulic drive mechanism, and be arranged on two groups of scissor-type bracing frames between base 15 and the bearing surface 1, the scissor-type bracing frame comprises lateral branch strut 3 and the medial branch strut 21 that is hinged by bearing pin 20.Base 15 and bearing surface 1 all are tower structures, and wherein: the junction of the back frame frame left and right with it of base 15 all is fixed with undersetting 19, and the junction of the back frame frame left and right with it of bearing surface all is fixed with upper bracket 4; Be respectively equipped with glidepath 16 in the left and right frame of base 15, be fixed with two between the front bezel of bearing surface 1 and the intermediate transverse girder and go up slide rail 8.

The upper end of described two lateral branch struts 21 is hinged and connected to respectively on the upper bracket 4 on the bearing surface 1, the lower end is separately installed with bottom roller 17, in the corresponding respectively glidepath 16 that is arranged on the base 15 of bottom roller 17, glidepath 16 can guarantee lower sheave 17 horizontal rolling on fore-and-aft direction.The lower end of described two medial branch struts 21 is hinged and connected to respectively on the undersetting 19 on the base 15, the upper end is separately installed with upper roller 7, in the corresponding respectively last slide rail 8 that is arranged on the bearing surface 1 of upper roller 7, last slide rail 8 can guarantee upper roller 7 horizontal rolling on fore-and-aft direction.

Be provided with the cross tube 5 of level between the two medial branch struts 21, the two ends of cross tube 5 are vertically fixed on the top of two medial branch struts 21 respectively, are fixed with at least two upper brackets 9 on the cross tube 5.Be provided with the sheer pole 18 parallel with cross tube 5 between the two lateral branch struts 3, the two ends of sheer pole 18 are vertically fixed on the bottom of two lateral branch struts 3 respectively, are fixed with at least two lower brackets 13 on the sheer pole 18, and lower bracket 13 is corresponding one by one with upper bracket 9.
