The invention discloses bridge big-height lifting displacement equipment based on a vehicle set and a construction method thereof. The equipment comprises the vehicle set and a lifting transfer support module; the vehicle set is arranged at the lower part of the lifting transfer support module; the lifting transfer support module comprises at least two rows of conversion connecting beams longitudinally arranged; multiple beam lower outer stand columns, vertically arranged in parallel, are fixedly mounted at the lower parts of each row of the conversion connecting beams; multiple beam lower inner stand columns, corresponding to the beam lower outer stand columns, are arranged on the inner sides of the beam lower outer stand columns; the tops of the beam lower inner stand columns are fixedlyconnected with the bottoms of the conversion connecting beams; the bottoms of the beam lower inner stand columns are fixedly connected with the vehicle set; multiple beam upper support stand columns,vertically arranged in parallel, are fixedly mounted at the upper parts of the conversion connecting beams; upper distribution beams are fixedly mounted on the beam upper support stand columns; and connecting brackets for supporting beam bodies are arranged on the distribution beams. The equipment is simple in lifting displacement structure and convenient to assemble, and can realize quick disassembly, replacement and shifting of big-clearance bridges (groups).

The invention discloses a multifunctional building block separator. The multifunctional building block separator comprises a steel travelling car, a lifting frame, fixed cross beams and moveable cross beams, wherein the fixed cross beams are fixedly arranged below a big girder of the steel travelling car; the moveable cross beams are moveably arranged above the fixed cross beams and are pushed bya separating device; the lifting frame passes through the places between the front fixed cross beam and the rear fixed cross beam, and between the front moveable cross beam and the rear moveable cross beam, and is driven through a lifting device to vertically ascend and descend; a supporting hook used for supporting the bottom plate of a concrete building block is arranged at the bottom of the lifting frame; a lower clamping device is arranged on the front fixed cross beam and the rear fixed cross beam respectively; and an upper clamping device is arranged on the front moveable cross beam andthe rear moveable cross beam respectively. Movement of equipment in a transverse travel can be realized; the upper layer and the lower layer of the autoclaved concrete building block are automatically separated; the displacement of the bottom plate after building block separation is realized; the production efficiency is improved; and the requirement of transportation of the building block is met. When the multifunctional building block separator is compared with the prior art, the number of the equipment is reduced, a labor field is saved, the labor intensity is lessened, the production efficiency is improved, and huge social benefit and economic benefit are brought to users.

The invention relates to a portal crane. The portal crane comprises a crane body and a moving mechanism arranged at the bottom of the crane body; the crane body comprises a pair of bases, lifting mechanisms arranged on the bases, a cross beam connected between the tops of the lifting mechanisms and a slidable lifting sling which is movably arranged on the cross beam; the slidable lifting sling comprises a drive lifting sling body, a driven lifting sling body connected with the drive lifting sling body and a power part used for driving the drive lifting sling body to slide; and the drive lifting sling body comprises fixing brackets, lifting plate assemblies connected to the fixing brackets and rolling assemblies connected to the bottoms of the fixing brackets, the rolling assemblies are arranged on the cross beam, and the power part is located under the cross beam. According to the portal crane, displacement and adjustment of the lifting sling on the cross beam are achieved, the slidingdistance is increased, sliding is more convenient and more flexible, and maintenance is not needed; and a modular car or a guide rail can be adopted as the moving mechanism, and therefore selection is flexible and diverse.

The invention discloses a corner guide rail bracket shifting device and a corner guide rail bracket shifting mounting method. The corner guide rail bracket shifting device comprises at least one sub-corner guide rail bracket shifting device, a plurality of moving rails, a plurality of moving rollers, a plurality of driving motors, a plurality of guide rail bracket fixing pieces and a control device; the sub-corner guide rail bracket shifting device comprises a rail support hung on one side of a transverse bulkhead; the moving rails are arranged on the rail support in parallel at intervals in the length direction of the rail support; each moving rail is provided with one moving roller; the driving motors are correspondingly connected with the moving rollers and are used for driving the moving rollers to slide along the moving rails; the guide rail bracket fixing pieces are used for fixing a corner guide rail bracket on the moving rollers; and the control device is connected with the control ends of the driving motors, and the control device controls the driving motors to work. By means of the corner guide rail bracket shifting device and the corner guide rail bracket shifting mounting method, the scattered corner guide rail bracket of a container ship can be shifted and mounted in a convenient, safe and rapid way.
