the portal comprises a cross beam, a cross beam strut assembly and a bottom beam, wherein the cross beam is connected with the bottom beam through the cross beam strut assembly;

the lifting jack is fixed on the cross beam, the oil pump provides power for the lifting jack, and the lifting jack drives the lifting appliance to lift through the steel strand; the lifting appliance is connected and fixed with the U-shaped beam.

The beam and pillar assembly is fixed by two beams in a crossed manner, and the beam and pillar assembly and the bottom beam form a triangular structure.

Still include the locating pin, the hoist passes through the locating pin and is connected fixedly with U type roof beam.

The working principle is as follows: the utility model discloses depositing of U type roof beam is carried the device, utilizes the mobile crane to deposit two sets and carries the unit and remove the both ends to U type roof beam respectively, and the control oil pump adjusts continuous jack, makes the hoist and mount hole position of falling to U type roof beam, passes U type roof beam hole of hoist through the locating pin and fixes the back, and the control oil pump adjusts continuous jack, makes jack piston and hydro-cylinder along steel strand wires relative motion, mentions U type roof beam to the height and is greater than the sweep height, stops to rise. And (4) controlling an oil pump and adjusting a continuous jack when the girder transporting vehicle runs to the bottom of the U-shaped girder after being lifted, enabling the U-shaped girder to stably descend to the vehicle plate to finish loading, contacting with a lifting appliance, and finishing lifting the girder.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses depositing of U type roof beam is carried device, simple structure can accomplish through the small-size loop wheel machine of single unit and remove, conveniently deposits the roof beam field and uses temporarily, makes the place utilize the maximize when practicing thrift the jack-up cost, improves a roof beam efficiency.

Detailed Description

As shown in fig. 1 to 3, the storage and lifting device for U-shaped beams of the present invention comprises a plurality of storage and lifting units, wherein in each storage and lifting unit, 1 is a gantry, and the whole storage and lifting unit is of a structure like a Chinese character 'men'; 2 is a continuous jack; 3 is a steel strand; 4 is a lifting appliance; 5 is a positioning pin; and 6 is an oil pump.

The whole portal that is "door" style of calligraphy structure, the portal include crossbeam, crossbeam pillar subassembly and floorbar, are connected through crossbeam pillar subassembly between crossbeam and the floorbar. The beam and column assembly is fixed by two beams in a cross mode, and the beam and column assembly and the bottom beam form a triangular structure, so that the overall structural stability is guaranteed. The crossbeam both ends are equipped with the lug, realize the device's transfer through car hoist and mount.

And the two continuous jacks 2 are vertically welded on the cross beams of the front and rear door frames 1 and are synchronously controlled by an oil pump 6. The steel strands 3 are multiple and penetrate through the continuous jack 2 and the cross beam to be connected and fixed with the lifting appliance 4. The lifting appliance 4 is of an inverted T-shaped structure and is fixedly connected with the steel strand 3, symmetrical positioning pins 5 are arranged on two sides of the lifting appliance, and the positioning pins 5 penetrate through the U-shaped beam lifting holes to be fixed.

As shown in fig. 4, utilize the crane will the utility model discloses two sets of lifting devices remove to U type roof beam both ends respectively, and control oil pump 6 adjusts continuous jack 2, makes hoist 4 coincide with U type roof beam hoisting point, all is connected fixedly hoist 4 and U type roof beam through locating pin 5, prepares to lift by crane.
