Abstract

The invention discloses a rotary cantilever crane for columns, which is characterized in that the crane is composed of an upper clamp, a lower clamp, an upper circular track, a lower circular track, a cantilever, a cantilever angling strut, an upper change gear, a lower change gear, a concrete column and an electric hoist, wherein the upper clamp tightly clamps the upper part of the concrete column and is fixedly connected with the upper circular track, the lower clamp clamps the lower part of the concrete column and is fixedly connected with the lower circular track, the upper change gear is connected with the root part of the cantilever and in rolling connection with the upper circular track through the upper change gear, the lower change gear is connected with the lower end of the cantilever angling strut and in rolling connection with the lower circular track through the lower change gear, the upper end of the cantilever angling strut is hinged with the middle part of the cantilever, and the electric hoist is hung on the cantilever in a rolling mode; and the cargo lifting is realized through the electric hoist, an operation that the cantilever rotates around the concrete column is realized through pulling the cantilever angling strut, and then cargo moving is realized.

Description

A kind of post is with turning round cantilever crane

Technical field

The present invention relates to a kind of post with turning round cantilever crane.

Background technology

The lifting tool of many workshops all is to select this larger equipment of driving, from economic angle, some units did not all use several times in certain 1 year, trace it to its cause, be originally that general workshop all has concrete post, be used for installing driving as concrete post, the makers' expert of lifting appliance drives a vehicle for your suggestion exactly, it is exactly the column cantilever crane, this column cantilever crane price is still expensive, can collide with the concrete post in workshop during prior suspending arm rotary, in other words area coverage at most can only 180 degree, not utilize be unreasonable to our concrete post of noticing workshop for this reason, the invention that Here it is will say below us.

Summary of the invention

Technical scheme of the present invention is:

1. a post is used and is turned round cantilever crane, by front band, and lower catch hoop, upper circuit orbit, lower circuit orbit, cantilever, the cantilever diagonal bracing bar, upper change gear, lower change gear, concrete post, electric block forms.

2. front band tightly blocks the top of concrete post and fixed with upper circuit orbit, lower catch hoop tightly blocks the bottom of concrete post and fixed with lower circuit orbit, upper change gear connects with the cantilever root and connects with upper circuit orbit rolling by upper change gear, lower change gear rolls with lower circuit orbit with the lower client link of cantilever diagonal bracing bar and by lower change gear and connects, the upper end of cantilever diagonal bracing bar and cantilever middle part are hinged, and electric block rolls and is suspended on the cantilever.

3. realize the goods lifting by electric block, by promoting the cantilever diagonal bracing bar, realize that cantilever rotates around concrete post, and then realize goods movement.

The present invention suits measures to local conditions, and is simple in structure, economical and practical.

The specific embodiment

Implement the present invention, at first will determine the purposes of concrete post, so long as the concrete post of load-bearing, it is more than sufficient in general lifting by crane 2 tons, is exactly that welding technique will be got well in addition, and the material of trying to win sb.'s favor is antirustly to process at last; The present invention suits measures to local conditions, and is simple in structure, and price is very cheap, can turn round cantilevers by 360 degree, and the lifting area coverage is large.

Claims

1. a post is characterized in that with the revolution cantilever crane :Described loop wheel machine is by front band, lower catch hoop, and upper circuit orbit, lower circuit orbit, cantilever, the cantilever diagonal bracing bar, upper change gear, lower change gear, concrete post, electric block forms.

2. a kind of post according to claim 1 is with turning round cantilever crane, be further characterized in that: front band tightly blocks the top of concrete post and fixed with upper circuit orbit, lower catch hoop tightly blocks the bottom of concrete post and fixed with lower circuit orbit, upper change gear connects with the cantilever root and connects with upper circuit orbit rolling by upper change gear, lower change gear rolls with lower circuit orbit with the lower client link of cantilever diagonal bracing bar and by lower change gear and connects, the upper end of cantilever diagonal bracing bar and cantilever middle part are hinged, and electric block rolls and is suspended on the cantilever.

3. a kind of post according to claim 1 is further characterized in that: realize the goods lifting by electric block, by promoting the cantilever diagonal bracing bar, realize that cantilever rotates around concrete post, and then realize goods movement with the revolution cantilever crane.
