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, the lifting of need overturning of the mould vehicle of aerocrete unit, this has higher squareness and stationarity when requiring the hoisting crane lifting, with damage and the displacement of avoiding aerocrete unit, and the common hoisting crane lifting form that adopts now is a steel wire rope type, and the operation lifting is very not steady, and squareness is difficult to guarantee; What spanner adopted when mould vehicle group moulding/demoulding is mechanical linkage, causes not pressing tightly mould easily, and therefore existing hoisting crane all is difficult to reach requirement technically with on the structure.

Summary of the invention

The purpose of this utility model provides a kind of special overturn hoisting crane of aerocrete unit mould vehicle, can realize stationarity and the squareness of mould vehicle when upset, and accurate positioning, and cost is lower.

The purpose of this utility model is achieved in that

Described upset hoisting crane, its version adopts electric block double girder crane crane span structure, its hoisting way adopts sprocket wheel to promote, wherein on the girder of crane span structure, be fixed with two vertical tracks vertically downward, operation has the I shape framework that is made of two suspender legs and the spanner crossbeam that installs betwixt between two vertical tracks, the other end that this spanner crossbeam is fixed with chain and this chain is connected with hydraulic efficiency gear on being packed in girder by sprocket wheel, on this spanner crossbeam, be fixed with the spanner of group moulding/demoulding, the lower end of one of two suspender legs laterally installs the hand that is coupling that a setting-in is touched the tool car, and the lower end of another suspender leg is equipped with and clamps the upset assembling of touching the tool car.

In addition, be fixed with bracket of rear mounting and side bracing frame respectively 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, spanner crossbeam position are installed; Described spanner is by fluid motor-driven, and described upset is assembled into the anchor clamps that clamp of the Driven by Hydraulic Cylinder that is packed in suspender leg lower end part.

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 hydraulically powered sprocket wheel to promote, and the technology comparative maturity hoists and moves 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 upset precision of mould vehicle;

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. the upset of the spanner of the group mould of mould vehicle and the demoulding and mould vehicle all adopts hydraulic efficiency gear to drive, and has greatly improved mechanism's traveling comfort, and pressing mold is tighter;

5. entire mechanism is fairly simple, and is reliable, smooth performance, and accurate positioning, cost is low, and the life-span is long, can effectively be implemented in the stationarity and the squareness of mould vehicle loading and unloading and upset.

The specific embodiment

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

This hoisting crane that overturns, its version adopts electric block double girder crane portal structure, promptly be fixed with end carriage 1 and constitute portal structure at the two ends of two parallel girders 8, medium position at girder is fixed with hydraulic efficiency gear (oil cylinder) 6, this hydraulic efficiency gear leads by hydraulic pressure supporting seat 7, the Trolley 11 that its end is moved on the track of girder by chain 9 tractives one, this Trolley is connected with the lifting thing by the chain wheel set 12,5 that is packed on the girder.On the end carriage at the two ends of this girder, be equipped with may operate on the bracket I-beam section the wheel (not shown), this end carriage is realized the walking of portal structures by drive motor 2.Be fixed with two vertical tracks 16 vertically downward on the girder of crane span structure, all be fixed with bracket of rear mounting 3 and side bracing frame 4 (referring to Fig. 5 and Fig. 6) 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, hydraulic efficiency gear all 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 15 on two vertical tracks, is fixed with spanner crossbeam 10 between these two suspender legs, constitutes one I shape framework.Chain wheel set on this spanner crossbeam on the corresponding girder is fixed with chain, makes chain wheel set pass through the lifting that hydraulic ram tractive chain is realized the spanner crossbeam.Three track adjusting wheels 13 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. 7, be packed in horizontal track adjusting wheel 22 on the suspender leg in the transversely displacement of vertical track, meanwhile, vertical track longitudinally two relative vertical track adjusting wheels 21 at the longitudinal travel of vertical track, can guarantee like this suspender leg the vertical track operation steadily and guarantee high verticality.

Be fixed with the spanner 14 of group moulding/demoulding on the spanner crossbeam, this spanner can unclamp or tighten the leading screw of mould vehicle by fluid motor-driven, realizes group mould, the demoulding of mould vehicle 20 (among Fig. 1 shown in the dotted line), and the spanner in the present embodiment is two.The lower end of one of two suspender legs laterally installs the hand 19 that is coupling that a setting-in is touched the tool car, and the lower end part of another suspender leg is equipped with and clamps the upset assembling of touching the tool car.

The upset assembling is packed in suspender leg lower end, mainly by clamping anchor clamps 18 and hydraulic ram 17 constitutes, the end of the piston rod of this hydraulic ram is packed in the eccentric position that clamps anchor clamps, be implemented in piston rod and stretch out to make and clamp anchor clamps upsets, these two ends that clamp anchor clamps be shaped on clamp mould vehicle collude the shape thing.

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 spanner crossbeam are constituted passes through hydraulic efficiency gear, chain wheel set, chain 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, the hand that is coupling clamps mould vehicle and can realize upset with the upset assembling, spanner on the spanner crossbeam is realized the group moulding/demoulding work of mould vehicle, after the squareness of vertical track and stationarity are passed through, the side bracing frame guarantees that the squareness of suspender leg and vertical track and stationarity realize by three track adjusting wheels.
