Abstract

The utility model relates to a crane special for use in machining production. The crane comprises a base and an upright post fixed to the base, wherein a cantilever is fixed to the top end of the upright post; a driving device and a transmission device are fixed to the upright post and the cantilever; the tail end of the transmission device is provided with a lifting hook. The crane is characterized in that the entire upright post is partitioned into three segments; the upper two sections of the upright posts are assembled telescopic-rod upright posts; the upper end of the upright post at the middle segment is provided with a fixing pin; at the upper two segments of the upright post, the heights of the telescopic upright posts are adjusted by adjusting the fixing pin; the lower two segments of the upright post are assembled rotary upright posts which can rotate around a longitudinal axle center; the lower two segments of the upright post are connected with each other through a rolling bearing. The crane has the beneficial effects that since the entire upright post has a three-segment structure, a workpiece can be moved conveniently after height adjustment and rotation by a certain angle. The crane can be conveniently applied to machining production, and the working efficiency is increased greatly.

In figure, 1, base, 2, column, 3, cantilever, 4, suspension hook, 5, set pin, 6, antifriction-bearing box, 7, driven fixed pulley, 8, cantilever fixed pulley, 9, movable pulley, 10, driving gear, 11, reducing gear, 12, handwheel, 13, front-wheel, 14, trailing wheel, 15, push and pull bar, 16, position fixing knob.

The specific embodiment

The utility model is that a kind of machine up is produced Special crane, because column entirety is three-stage structure, can carry out easily carrying out after the adjustment, the anglec of rotation of height the movement of workpiece, can application in machine up is produced easily, greatly improved work efficiency.

Below in conjunction with accompanying drawing, the utility model is described further.

Specific embodiment, as Fig. 1, shown in Fig. 2, a kind of machine up is produced Special crane, comprise base 1 and be fixed on the column 2 on base 1, on the top of column 2, be fixed with cantilever 3, on column 2 and cantilever 3, be also fixed with actuating device and driving device, the end of driving device is provided with suspension hook 4, described column 2 entirety are three-stage structure, in order to adapt to the working environment of differing heights, by upper two sections of column 2, be made as the Telescopic shaft type column assembling, column upper end at interlude is provided with set pin 5, by adjusting set pin 5, adjust the height of Telescopic shaft type column for upper two sections of column 2, for convenient, workpiece is moved to adjustment, be made as the rotary column that can rotate around longitudinal axis center assembling by lower two sections of column 2, between lower two sections of column 2, by antifriction-bearing box 6, be connected.
