Description
Technical field
This utility model is related to the structure improved technology of large lifting equipment, especially improved gantry crane.
Background technology
Gantry crane is as what the development of harbour cause got up.1890, for the first time that amplitude is immutable
Fixed rotatable jib-type crane be contained on operation type half gate seat being across above narrow harbour, become early stage port use
With the increasing of harbour width, gate seat and half gantry crane develop half gantry crane side by side, and commonly used pitching arm support
With level luffing system.After World War II, port gantry crane develops rapidly for ease of multiple stage crane to same
Bar ship is worked side by side, commonly used rotating part rotary-column type gantry crane (Fig. 1 [rotary-column type even with column body phase
Gantry crane]), or the rolling bearing type supporting rotaring device that rotating part is connected with gate seat by big bearing, turned with reducing
The tail footpath of dynamic part, and employ gate seat structure to reduce the projection to ground for the gate seat main body, that is, reduce harbour and cover face.Sending out
During exhibition, gantry crane also progressively promotes the use of the operating condition building berth close with harbour and power station building site etc..
Gantry crane is that crane span structure passes through jib-type crane on ground rail or ground for the both sides outrigger support.Have
Run along ground rail, rolling stock or other surface cars can be passed through down.Rotatable hoisting apparatus is contained in a shape mounting
On a kind of jib-type crane.4 lower limbs of door shape mounting constitute 4 " door opening ", be available for rolling stock and other vehicles pass through.
Gantry crane runs along the crane runway on ground or building mostly, carries out lift operation.Gate seat is in " " font
Crane claim half gantry crane, the side of its running track sets on the ground, and opposite side is located at the building being above the ground level
On.
Gantry crane adopts level luffing system mostly.1. weight and the respective center of gravity of boom system are in amplitude changing process
Almost without vertical displacement.One of its method is to balance the liter of synthesis center of gravity during boom system pitching by setting up activity balancing again
Fall change this method arrangement is more convenient, and work is also relatively reliable, is widely used.The two of method are the mechanism characteristicses by boom system
To ensure to synthesize the motion track of center of gravity during luffing close to horizontal line, non-activity balance weight.2. lifted weight is in amplitude changing process
Move along being bordering on horizontal track, can be using penalty method and combination arm support method.Penalty method is to be existed by extraordinary storage rope system
The corresponding raising line of automatic deploying and retracting in amplitude changing process, to compensate the suspender vertical displacement that arm support lifting causes.Combination arm support method be according to
Mechanism characteristicses by combining arm support ensure that arm end is close in amplitude changing process and move horizontally.Both of which is used widely.
Shipbuilding gantry crane is mainly used in building berth, floating dock and tie boat anlongshore dress scene, carries out the slingers such as hull splicing, equipment tie boat anlongshore dress
Make, with suspension hook as suspender, the biggest lifting capacity reaches 300 tons, be suitable for big elevating height, significantly with small distance operation will
Ask, with production-scale continuous expansion, existing gantry crane cannot meet the big distance lifting of little tonnage.
