Abstract

The invention relates to a special lifting appliance for an engine cylinder. The special lifting appliance comprises a box body, a main shaft, a main shaft sleeve, a reversing shaft with the lower endbeing provided with an inverted T-shaped armature, a guide plate, a positioning pin, a grab fixing shaft, a guide shaft, two pairs of connecting rods I, two pairs of connecting rods II, two pairs ofgrabs, a rising lug, a movable tongue and a positioning pin. The reversing shaft comprises a reversing shaft main body and a reversing shaft sleeve, the reversing shaft sleeve is provided with an upper circle and a lower circle of oblique teeth which alternatively correspond to each other, the upper circle and the lower circle of oblique teeth are respectively provided with four oblique teeth, andthe upper two adjacent oblique teeth or the lower two adjacent oblique teeth are separated from 90 degrees. The reversing shaft is installed inside the main shaft and can move up and down inside themain shaft, the positioning pin penetrates through the main shaft, and a head part of the positioning pin is inserted between the upper and lower oblique teeth of the reversing shaft sleeve. The two pairs of connecting rods II, the two pairs of connecting rods I and the two pairs of grabs form a multi-connecting-rod mechanism which is fixed on two sides of the main shaft by virtue of the guide shaft. A T-shaped through hole is arranged in the grab fixing shaft, and the movable tongue is arranged in the T-shaped through hole. The upper end of the grab fixing shaft is also provided with the rising lug, and a groove matched with the inverted T-shaped armature is arranged in the grab fixing shaft.

Description

technical field [0001] The invention relates to a special sling for engine cylinders, which belongs to the field of sling equipment for automobile manufacturers. Background technique [0002] At present, the hanger used by the car coupler in the automobile manufacturing factory to lift the automobile engine cylinder is mainly composed of a connecting pin, a suspension shaft, a transmission pin, a cam armature, a clamping block and a rotating shaft. The cam armature of this kind of automobile engine cylinder block spreader is square. When lifting, during the swinging process of the cylinder block, the clamping block is easy to squeeze the cam armature and move upward, and the rotating shaft is easy to bend and deform, which eventually leads to derailment accidents, that is, decoupling, which has a major impact on the safety of enterprise production. [0003] In addition, there is currently an engine cylinder hanger, which consists of a connecting pin, a hanging shaft, a posit...
