CN202089704U - Cantilever crane - Google Patents

Abstract

A cantilever crane is characterized in that an upper fixing seat and a lower fixing seat are mounted on a support frame column; a vertical cantilever shaft is mounted between the upper and the lower fixing seats; two ends of the cantilever shaft are connected with the upper and the lower fixing seats through bearings; a transverse cantilever is mounted on the cantilever shaft; and a hoist is mounted on the cantilever. The utility model solves the problem that the idleness for waiting for the traveling cranes is caused since the number of traveling cranes in a machine shop is relatively small, and is particularly suitable for hoisting workpieces in steel structure workshops.

Description

Cantilever hangs

Technical field

The utility model relates to the parts mobile field of machine up, a kind ofly specifically is used for the simple lifting tool that machine shop is moved workpiece.

Background technology

The steel-structure factory building workshop each to stride the Fabricating machinery of arrangement a lot, need the workpiece of lifting also a lot, and the problem of the work holdup often appears because waiting driving in the driving negligible amounts.

The utility model content

The utility model causes because of waiting problem of the driving work holdup for solving machine shop driving negligible amounts, and a kind of easy cantilever device for hoisting is provided.

The technical solution of the utility model is, a kind of cantilever hangs, its special character is, on the side wall support trestle of steel-structure factory building, install following two permanent seats, vertical projecting shaft is housed between the permanent seat, the projecting shaft two ends are connected with permanent seat by bearing, and horizontal cantilever is housed on the projecting shaft, and hoist is housed on the cantilever.

Do 180 degree rotations cooperating between the reliable projecting shaft of cantilever and permanent seat, the bearing, hoist can be on cantilever side travel, can finish the required lifting operation of equipment on the hoist as long as the workpiece of Tape movement is suspended to during use.

Technique effect of the present utility model is, adopts technique scheme, can realize that a kind of cost is low, manufactures easyly, both can improve work efficiency, can reduce the overhead hoist of labor strength again.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.

In the drawings, 1 support trestle, 2 bearings, 3 permanent seats, 4 projecting shafts, 5 cantilevers, 6 hoists.

The specific embodiment

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

As shown in the figure, support on the trestle 1 and install following two permanent seats 3, vertical projecting shaft 4 is housed between the permanent seat 3, projecting shaft 4 two ends are connected with permanent seat 3 by bearing 2, and horizontal cantilever 5 is housed on the projecting shaft 4, and hoist 6 is housed on the cantilever 5.

Do 180 degree rotations cooperating between cantilever 5 reliable projecting shafts 4 and permanent seat 3, the bearing 2, hoist 6 can be on cantilever 5 side travel, can finish the required lifting operation of equipment on the hoist 6 as long as workpiece is suspended to during use.

Claims (1)

1. a cantilever hangs, and it is characterized in that: install following two permanent seats on the support trestle, vertical projecting shaft is housed between the permanent seat, the projecting shaft two ends are connected with permanent seat by bearing, and horizontal cantilever is housed on the projecting shaft, and hoist is housed on the cantilever.
