Abstract

The utility model belongs to an in and out kettle crane of special equipment for aerated concrete; the essential technical structure is that two vertical orbits are vertically and downwards fixed on the main beam of a bridge beam; lifting tool legs are respectively and synchronously operated on the vertical orbits; the steel cable of a fixed pulley arranged on the horizontal frame of the pulley is driven by the three-in-one drive device arranged on the bridge beam. The whole mechanism has simple structure, reliable operation and low cost; the stationarity and the perpendicularity of the hoisting during the in and out kettle hoisting of the aerated concrete member can be effectively realized; the utility model can be specially used as in and out kettle hoisting equipment for the aerated concrete, and can be applied to various high perpendicularity and stationarity hoisting occasions.

Description

Discrepancy still hoisting crane

Affiliated field

The utility model belongs to the hoisting crane field, is a kind of specialized equipment of aerated concrete---the still hoisting crane of coming in and going out.

Background technology

Along with China's rapid economy development, the construction of Infrastructure is very busy, and the progress of science and technology is applied in the construction of Infrastructure more up-to-date technology new product.Aerocrete unit has incomparable high performance as an emerging building materials, is widely used in the various buildings, and supply falls short of demand for product.Yet, in the manufacturing process that carries out the aerocrete unit automatic production line, when aerocrete unit lifts into still and lifts out still, have higher squareness and stationarity when requiring the hoisting crane lifting, and existing common hoisting crane is difficult to all reach technically with on the structure.

Summary of the invention

The purpose of this utility model provides the come in and go out special purpose crane of still of a kind of aerocrete unit, lifting stationarity and squareness when can be implemented in aerocrete unit and going out, go into the still lifting.

The purpose of this utility model is achieved in that

The version of described discrepancy still hoisting crane adopts electric block double girder crane crane span structure, its hoisting way adopts rope hoisting, wherein on the girder of crane span structure, be fixed with two vertical tracks vertically downward, the suspender leg is arranged and between these two suspender legs, be fixed with a pulley crossbearer in equal synchronized operation on these two vertical tracks, the other end that is fixed with fixed pulley on this pulley crossbearer and twines the steel rope on this fixed pulley drives the corresponding respectively anchor clamps that are fixed with in suspender leg lower end by the three-in-one actuating device on the crane span structure.

In addition, all be fixed with bracket of rear mounting and side bracing frame on two vertical tracks, the other end of this bracket of rear mounting and side bracing frame is packed on the girder respectively; What vertical shifting was passed through about the suspender leg carried out on vertical track is three track adjusting wheels that its top and position, pulley crossbearer position are installed.

Advantage of the present utility model and good effect are:

1. version adopts existing electric block double girder crane crane span structure, hoisting way to adopt rope hoisting, and the technology comparative maturity promotes and move secure;

2. on two vertical tracks, all be fixed with bracket of rear mounting and side bracing frame, can effectively realize the squareness and the stationarity of vertical track, guaranteed the lifting precision of aerocrete unit;

3. the suspender leg operates on the vertical track by three track adjusting wheels, has ensured the squareness and the stationarity of the upper and lower displacement of suspender leg, has improved the precision of entire mechanism operation;

4. entire mechanism is simple in structure, reliable, cost is low, aerocrete unit be can effectively be implemented in and still the lifting stationarity and the squareness in when lifting gone out, go into, not only can be used as the special use discrepancy still weight-lifting equipment of aerated concrete, and can be applied in the various lifting occasions that need high verticality and the lifting of high stationarity.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is further described:

This still hoisting crane of coming in and going out, its version adopts electric block double girder crane portal structure, promptly be fixed with end carriage 1 respectively and constitute crane span structure at the two ends of two parallel girders 8, medium position at girder is fixed with three-in-one actuating device 9, this three-in-one actuating device is made of electrical motor, speed reduction gearing and drg, is fixed with the reel of lay winding wire ropes 7 on speed reduction gearing; This steel rope is connected with the lifting thing by the fixed pulley 6 that installs on the girder.Be equipped with in the end carriage bottom may operate on the bracket I-beam section 2 the wheel (not shown), this end carriage is by the I-beam section drive axle shelf structure walking of drive motor 3 at bracket.Be fixed with two vertical tracks 10 vertically downward on the girder of crane span structure, all be fixed with bracket of rear mounting 4 and side bracing frame 5 (referring to Fig. 3 and Fig. 4) on these two vertical tracks, the other end of this bracket of rear mounting and side bracing frame is packed in respectively on the girder of a corresponding side.Vertical track and fixed pulley (two fixed pulleys about being generally) are to be packed on the girder by laterally being packed in two installation crossbeams (not having label) on the girder.All operation has suspender leg 12 on two vertical tracks, between these two suspender legs, be fixed with pulley crossbearer 14, the other end that two fixed pulleys on this pulley crossbearer on the corresponding girder are fixed with two fixed pulleys 13 and twine the steel rope on this fixed pulley by the fixed pulley on the crane span structure girder with three-in-one actuating device reel is connected realization moving up and down to pulley crossbearer, this I shape framework of suspender leg.Suspender leg lower end correspondence respectively is fixed with anchor clamps 15, and these anchor clamps can be made different shape according to the needs of reality lifting, and present embodiment is touched the plate shaped of tool for lifting is dull and stereotyped.

Three track adjusting wheels 11 that vertical shifting was installed by its top and position, pulley crossbearer position about the suspender leg carried out on vertical track, its concrete structure is referring to Fig. 5, be packed in horizontal track adjusting wheel 17 on the suspender leg in the transversely displacement of vertical track, meanwhile, at the vertical track adjusting wheel 16 of vertical track two symmetrical installations longitudinally longitudinal travel at vertical track, can guarantee like this suspender leg the vertical track operation steadily and guarantee high verticality.Vertical track in this device and suspender leg are made by rectangular steel pipe.All affixed modes are that bolt is affixed.

Principle of work of the present utility model is:

The integral structure of this device is realized walking by the drive motor on the end carriage, the I shape framework that two suspender legs and pulley crossbearer are constituted is implemented in the vertical shifting (dotted line is depicted as the diagram of I shape framework walking in the upper limit in Fig. 1) of vertical track by steel rope-fixed pulley-three-in-one actuating device, the squareness of vertical track and stationarity guarantee that by back, side bracing frame the squareness of suspender leg and vertical track and stationarity realize by three track adjusting wheels.
