Abstract
The utility model discloses a kind of hinged door crane, it includes girder and electric block, the root of supporting leg is provided with the hinged-support above hinged-support and roller box by hinged under bearing pin composition supporting leg, the shaped upper part of described supporting leg is V-type, it is respectively arranged with upper hinge support on the V-type end face on described supporting leg top, cross-arm laterally rides in supporting leg upper end and forms on supporting leg hinged by the hinged-support under it with supporting leg upper hinge support bearing pin, the two ends of girder are welded with cross-arm, and the bottom of supporting leg and the centre of another supporting leg are hinged with lower tie-beam.Driving means is contained on roller box, and the quantity of described upper hinge support is eight.Run on I-steel below girder and have electric block.The technical program effectively alleviates the deadweight of supporting leg and grade beam, saves material, saves time, easy for installation during making, the generation of effective minimizing accident.
Description
Technical field
This utility model relates to crane, the door frame articulated structure on a kind of gantry crane.
Background technology
The electric block gantry crane of China at present, door frame thereon is mainly made up of grade beam, supporting leg, cross-arm and girder, and grade beam is connected with supporting leg lower end, supporting leg upper end is connected with girder cross-arm, time-consuming during installation, and bolt hole requires strand system, requirement on machining accuracy is high, corresponding cost is high, and being shaped as of supporting leg is up big and down small, integral solder, materials are many, from great, waste steel, make troubles to installation and transport.The crane of this structure is owing to being all rigidly connected, it is easy to occurring that three wheels land, another wheel is unsettled, the generation of easy induction accident.
Summary of the invention
Task of the present utility model is to propose a kind of to save material, alleviate the deadweight of grade beam, assembly and disassembly a kind of hinged door crane easily.
Task of the present utility model so completes, it includes girder and electric block, it is characterized in that: the root of supporting leg is provided with the hinged-support above hinged-support and roller box by hinged under bearing pin composition supporting leg, the shaped upper part of described supporting leg is V-type, it is respectively arranged with upper hinge support on the V-type end face on described supporting leg top, cross-arm laterally rides in supporting leg upper end and forms on supporting leg hinged by the hinged-support under it with supporting leg upper hinge support bearing pin, the two ends of girder are welded with cross-arm, and the bottom of supporting leg and the centre of another supporting leg are hinged with lower tie-beam.Driving means is contained on roller box, and the quantity of described upper hinge support is eight.Run on I-steel below girder and have electric block.
This utility model has the effect that the technical program effectively alleviates the deadweight of supporting leg and grade beam, saves material, saves time, easy for installation during making, the generation of effective minimizing accident.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is the side view of Fig. 1；Fig. 3 is the structural representation of lower supporting leg；Fig. 4 is the side view of Fig. 3.
Drawing illustrates: 1, driving means, 2, roller box, 3, hinged under supporting leg, 4, supporting leg, 5, hinged on supporting leg, 6, cross-arm, 7, girder, 8, electric block, 9, lower tie-beam.
Detailed description of the invention:
nullEmbodiment is described in detail in conjunction with the figures above，As shown in Figure 1，The root of supporting leg 4 is provided with hinged-support and roller box 2 hinged-support above by under bearing pin composition supporting leg hinged 3，Driving means 1 is contained on roller box 2，Described driving means is fixed with ground，The shaped upper part of described supporting leg is V-type，This shape one is to reduce material，Two is appearance looks elegant，Also the intensity on supporting leg top will not be reduced，It is respectively arranged with upper hinge support on the V-type end face on described supporting leg top，The quantity of described upper hinge support is eight，Cross-arm 6 laterally rides in supporting leg upper end and forms on supporting leg hinged by the hinged-support under it with supporting leg upper hinge support bearing pin，The two ends of girder 7 are welded with cross-arm，Run on the electric block 8 I-steel below girder，In order to make supporting leg more firm，The bottom of supporting leg and the centre of another supporting leg are hinged with lower tie-beam 9，The average holding capacity disperseing supporting leg.
Owing to structure is hinged, just can assemble on ground, then whole crane be erected, without Site Welding and work high above the ground, effectively reduce the generation of accident；Due between the parts in total for flexibly connecting, do not have three wheels and land, another wheel is unsettled, and is effectively reduced the deadweight of supporting leg and grade beam, saves substantial amounts of material simultaneously, reduces production cost.
