Abstract
The utility model relates to a self stress bridge type and gantry type crane. The utility model comprises a main beam, an end beam, a pulling trolley, a hoisting mechanism and a lifting rope, wherein the main beam adopts the structure of double open-web trusses, and a trolley running mechanism is arranged on a supporting position of the main beam; the hoisting mechanism is arranged on the upper end of the supporting position of the main beam, a wire rope of the hoisting mechanism passes round a fixed pulley at the lower end part of the main beam and a dead pulley on the pulling trolley, and the wire rope which passes through a movable pulley on a sling is fixed on the other end of the main beam; wheels of the pulling trolley are symmetrically hung on open-web H-shaped lower flanges at both sides of the main beam. At the lower part of the main beam, the self stress bridge type and gantry type crane of the utility model generates inverse bending stress which can counteract a part of positive bending stress, the own weight of the pulling trolley is light, the hoisting mechanism and the trolley running mechanism are fixed on the supporting position of the main beam, an electric conduction sliding touch device on the beam is saved, the factors totally cause that the own weight of the main beam is lighted, therefore the weight of the whole crane is reduced.
Description
Technical field
The utility model relates to hoisting crane, and is especially a kind of from stress bridge-type and transfer crane.
Background technology
Existing bridge-type and transfer crane, from metal construction, have single-beam, twin beams arranged, they hoist and operating unit all is located on the crane carriage, its deadweight accounts for 0.35-0.5 times of rated load weight, and the grab bucket that has is hung even reached 1 times, and dolly moves on beam, this part has influence on the strength and stiffness of metal construction from heavy lift, makes that the hoisting crane complete machine is heavy, wheel load is big, cost is high.
Summary of the invention
The purpose of this utility model just provides a kind of novel structure, little from heavy and light, wheel load, and band overload safe limit function from stress bridge-type and transfer crane.
Of the present utility modelly comprise girder, end carriage, trailer wagon, wheeling mechanism, lifting mechanism, steel rope from stress bridge-type and transfer crane, girder adopts two vierendeel truss formula structures, one end of girder and end carriage are bolted connection, the other end links to each other by bearing pin, form static determinacy three fulcrum structures, change traditional indeterminate four fulcrum structures; Wheeling mechanism is installed on the girder supporting position, lifting mechanism is arranged on the upper end of girder supporting position, the steel rope of lifting mechanism is walked around the dead sheave of girder bottom and the fixed pulley on the trailer wagon, and pass movable pulley on the suspender, be fixed on the other end of girder, constitute a bounded system of forming by many branch lines; The winch of lifting mechanism comprises that two are driven rope sheave and a storage rope sheave, the rope sheave that drives of one of them links to each other by sprocket wheel, chain or synchronous pulley, synchronous band with the storage rope sheave, driving rope sheave is winding of single layer, the storage rope sheave is multilaminate coiled, the safety clutch of overload safety guard-safeguard effect has been equipped with in storage in the rope sheave, and safety clutch also plays to make and driving rope and reach the consistent effect of rope speed by slippage with storing up to restrict; The wheel symmetry of trailer wagon is hung on empty stomach I shape lower flange, the both sides of girder, affixed track plate on the I shape lower flange, be to contact with track like this for wheel rim, wheel load is more even, wheel walking can the self-regulated guiding, the chassis side rail of trailer wagon by plain radial bearing with hang vehicle wheel frame and be connected.
Of the present utility model from stress bridge-type and transfer crane under lift heavy and deadweight loading, girder is when having born positive curve stress, the bottom of beam also has been subjected to one contraflexure stress that the tension wire rope produces, and contraflexure stress can be offset a part of positive curve stress.In addition, trailer wagon is from heavy and light, hoists and wheeling mechanism is packed in again on the supporting position of girder, and the conduction slide device has been save on the beam, and these factors all make the girder deadweight be alleviated greatly, thereby have reduced whole hoisting crane weight.
