Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] The left column 2 is fixed on the lower frame 1, the right column 9 is hinged on the lower frame 1, and the right column 9 can swing left and right. The hoop slider is sleeved on the column, and when the handle 11 is unclamped, the hoop slider can slide up and down along the column, and when the handle is locked, the hoop slider is fixed on the column. The upper and lower bars between the left columns in the figure are perpendicular to the columns and fixedly connected with the hoop slider, that is, the upper rail 8 is fixedly connected with the upper hoop slider 10, and the lower rail 3 is fixedly connected with the lower hoop slider 12. , the upper cross bar 8 and the lower cross bar 3 are parallel to each other, the two ends of the oil cylinder 5 are respectively hinged with the upper cross bar 8 and the lower cross bar 3, and the axis of the...

Abstract

The invention relates to a stepping type hydraulic elevating mechanism, which comprises an upper framework and a lower framework. The invention is characterized in that two parallel left upright columns are fixed on the lower framework, and two right upright columns are connected to the lower framework; an upper anchor ear slide block and a lower anchor ear slide block are arranged on each upright column, and locking devices are arranged on the anchor ear slide blocks; an upper cross bar is fixed between the upper anchor ear slide blocks on the left upright column, a lower cross bar is fixed between the lower anchor ear slide blocks, and the upper cross bar is parallel to the lower cross bar; an upper cross bar is fixed between the upper anchor ear slide blocks on the right upright column, a lower cross bar is fixed between the lower anchor ear slide blocks, and the upper cross bar is parallel to the lower cross bar; an oil cylinder is connected between the two groups of upper cross bars and the lower cross bars; the upper framework spans between the upper cross bars. The invention has the advantages that when the stroke of the oil cylinder is smaller, the distance from the upper framework to the lower framework can be small, if the upright column is enough high, the upper framework can be lift to a higher position, and is not limited by the stroke of the oil cylinder. The plane of the upper framework can be horizontal or declining, thereby providing convenience for adjusting the angle of the executive component of the device.

Description

technical field [0001] The invention relates to a hydraulic mechanical lifting mechanism, in particular to a stepping hydraulic lifting mechanism. With this mechanism, the object can be raised and lowered to the required height, or as the supporting part of the equipment, the execution part of the equipment can be lifted to the required height to start work. Background technique [0002] Present hydraulic lift, if want to realize higher hoisting height, usually adopts cylinder structure, or parallelogram form (also claims scissors type) frame. The former uses multi-stage cylinders to lift, and the latter uses oil cylinders to push the parallelogram frame to retract, which can realize the lifting of the mechanism platform. But these two structures are all more complicated, and the lifting height is limited by the stroke of the oil cylinder, and the height of the upper frame can not be very low relative to the lower frame. Contents of the invention [0003] In order to ove...
