Abstract
The utility model discloses a tool special for hoisting rack, which is provided for overcoming the shortcoming existing in the prior art that due to the fact that a steel wire rope or a hoisting belt is used for binding a luffing mechanism rack of a door machine for hoisting, the edge of a rack is easy to cut the steel wire rope or the hoisting belt, thereby being not safe. A hoisting lug is arranged at the top of a square steel hoisting frame for the luffing mechanism rack to be axially inserted in. Due to the fact that the tool for hoisting the luffing mechanism rack is the steel hoisting frame which enables the luffing mechanism rack to be axially inserted in, and the hoisting frame surrounds the transverse circumstance of the luffing mechanism rack. Compared the steel wire rope or the hoisting belt made by stranding, the hoisting frame is more firm, can not be cut and damaged by the edge of the rack, can not be fractured like the steel wire rope or the hoisting belt so as to lead the rack to fall off. The tool special for hoisting rack is simple in structure, and safe and reliable to use.
Description
Technical field
The utility model belongs to lifting device, specifically a kind of special tool of integral hoisting door machine luffing mechanism tooth bar.
Background technology
Many transfer cranes all are equipped with for large cargos such as handling freight containers, on the port and pier.Installing or during the luffing mechanism tooth bar of maintenance transfer crane, need overall package be good on the ground with the luffing mechanism tooth bar, and then lifting is transported on the gantry frame fixing.
Because described tooth bar weight is big, size is long, sling height is big, lifts very inconvenient.Traditional hanging method is: be bundled in steel rope or suspender belt on the tooth bar that assembles, catch on steel rope or suspender belt lifts with hoisting crane.Because rack flange is very sharp, be easy to will binding usefulness steel rope or suspender belt cut and draw damage, handling heavy weight rack member like this, steel rope and suspender belt be in case fracture, it is hardly imaginable that tooth bar falls down consequence, has great potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes existing luffing mechanism tooth bar lifting with steel rope or suspender belt binding door machine, and rack flange easily hurts steel rope or the unsafe shortcoming of suspender belt, and a kind of tooth bar lifting special tool is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the top in the square hanging box of steel that the luffing mechanism tooth bar can axially be inserted is provided with hanger.
The utility model also has following technical characterictic:
The bottom of described square hanging box is for flexibly connecting the limit;
The connection mode on described flexible connection limit is, falling on the framework of " U " font, is being positioned on the dual-side of nearly its lower ending opening and is provided with through hole, and pin can be through in the through hole on the framework dual-side with plugging;
Described pin can pass in the framework and be hung between two teeth of tooth bar;
The hanger of described frame roof, for along described length setting of falling " U " type framework top, erect on the fixing boatswain chair.
Advantage of the present utility model and good effect are, because the instrument of handling luffing mechanism tooth bar, be the steel hanging box that the luffing mechanism tooth bar can axially be inserted, hanging box is enclosed in the horizontal border of luffing mechanism tooth bar, steel rope or the suspender belt made compared with plying come, it is much firm that hanging box is wanted, and can not cut by rack flange and draw damage, and also fracture that can be not the same just like steel rope or suspender belt, the phenomenon that tooth bar is dropped take place.Above-mentioned tool construction is simple, and is safe and reliable.
Description of drawings
Fig. 1 looks scheme drawing for master of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, at the top of the square hanging box of steel of the axial insertion that can make luffing mechanism tooth bar 3, be provided with the hanger 4 of lifting usefulness, the centre of hanger 4 is provided with lifting hole(eyelet) 4.1.
The loading and unloading of tooth bar 3 for convenience, the bottom of described square hanging box is for flexibly connecting the limit, its connection mode is, falling on the framework 2 of " U " font, be positioned on the limit, the left and right sides of nearly its lower ending opening and be provided with through hole, pin 1 can be through in the through hole on the limit, framework 2 left and right sides with plugging, spring cotter 1.1 is inserted in pin 1 termination and is positioned at the hole of exposing side, can block pin 1 slippage from the side;
Certainly, the flexible connection limit of described hanging box also can be other flexible connection forms that make things convenient for folding.
Safety when lifting by crane tooth bar 3, the diameter of described pin 1 is for passing between two teeth 3.1 that hung tooth bar 3 in the framework 2 (referring to Fig. 2), like this, because the weight of tooth bar 3 is big, tooth bar 3 rides on the pin 1, two teeth 3.1 wherein can be pushed down pin 1 firmly, have guaranteed that tooth bar 3 axial slip can not take place in handling, and certainly the diameter of pin 1 is according to its Intensity Design that can bear.
More firm in order to make suspension hook collude framework 2, the hanger 4 at described framework 2 tops is for erectting the boatswain chair that fixedly installs along the length of described " U " type framework 2 tops.
When using above-mentioned instrument to lift luffing mechanism tooth bar 3, " U " type framework 2 that will fall earlier is buckled on the cross-sectional direction of tooth bar 3, to seal down the pin 1 that " U " font framework 2 under sheds are used, pass the open-work on framework 2 dual-sides, pin 1 exposes the termination of framework 2 and pins with spring cotter 1.1, formation is to the encirclement of tooth bar 3,3.1 in two teeth on the tooth bar 3 also may be stuck on the pin 1, tooth bar 3 can endwisely not slipped, and the suspension hook with crane colludes on the lifting hole(eyelet) 4.1 of hanger 4 on the described framework 2 and can lift by crane then.Above-mentioned lifting device is simple in structure, and is safe and reliable.When handling behind the destination, unclamp the suspension hook of crane, pull out spring cotter 1.1 and extract pins 1 out, can easily tooth bar 3 be unloaded in place in place.
