Abstract
The utility model relates to a two beam suspension crane, which comprises main beams, end beams and electric blocks and is characterized by adopting a two beam structure, which means the crane comprises two mutually parallel main beams. The electric blocks are installed on the two main beams through driving roller devices, the two end beams are connected with the two main beams, the end beams are perpendicular to the main beams, and the end beams and the main beams form a '#'-shape structure. The middle portions of the end beams form a recessed structure which is connected with the two main beams. The driving roller devices and stabilizing rollers are installed close to the two ends of the end beams, the two end beams are installed on a suspension track through the driving roller devices and the stabilizing rollers, and the stabilizing rollers are contacted with the lower end face of the track. The two beam suspension crane has the advantages of having a simple structure, a reliable performance and a high application safety factor and being capable of improving lifting range limit.
Description
Technical field
The utility model belongs to the handling machinery technical field, particularly relates to a kind of overhang crane of novel two-beam type.
Background technology
At present, overhang crane is widely used in fields such as nuclear power, metallurgy, machinery, chemical industry, oil and the energy.Existing overhang crane comprises girder and end carriage, article one, girder is installed on the suspended rail by two perpendicular end carriages, electric block is installed on the girder, electric block is installed on the girder by the drive roller wheel device, end carriage is installed on the suspended rail by the drive roller wheel device, girder is stress influence by bending, and the distance between two end carriages of girder bonded assembly should not be too far away, so end carriage one segment length generally will be stretched out in the two ends of the girder of hoisting crane, increase the left and right sides lifting limit range of hoisting crane with this, but, because of wall scroll girder intensity limited, the extended length at girder two ends also is restricted, and has limited the left and right sides lifting limit range of hoisting crane with this; In addition, when electric block moved to the end of girder, the running roller of the drive roller wheel device on the electric block end carriage far away can perk, thereby makes girder rock shakiness, and the weight of being sling by electric block very easily drops, and has serious potential safety hazard.
Summary of the invention
The utility model is for solving that the technical matters that exists in the known technology provides a kind of simple in structure, dependable performance, coefficient safe in utilization is high and can increasing the two-beam type overhang crane of lifting range limit.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of twin beams overhang crane, comprise girder, end carriage and electric block, it is characterized in that: described hoisting crane adopts two main beam structures, be that hoisting crane comprises two girders parallel to each other, described electric block is installed on two girders by the drive roller wheel device, connect two end carriages on two girders, described girder is vertical mutually with end carriage, and promptly two girders and two end carriages form the groined type structure; The middle part of described end carriage is a concave structure, and two girders are connected on the spill position of end carriage; Described two ends near end carriage are provided with drive roller wheel device and stable roller, and described two end carriages are installed on the suspended rail by drive roller wheel device and stable roller, and described stable roller contacts with the lower surface of track.
The utility model can also adopt following technical scheme:
Described drive roller wheel device comprise running roller and with running roller bonded assembly drive motor.
The two ends of described girder and suspended rail are equipped with limit switch.
Advantage and the good effect that the utlity model has are: because as above technical scheme of this novel employing, it is the structure that hoisting crane adopts two girders, electric block is installed on two girders, compare single girder trolley crane, article two, the intensity of girder has improved, so can increase the length of girder, especially the length of end carriage is stretched out at the girder two ends, has increased the left and right sides lifting limit range of hoisting crane.
The middle part of two end carriages of hoisting crane is a concave structure, and two girders are connected on the spill position of end carriage, like this, under the condition of orbit altitude inconvenience, can increase the limes superiors height of electric block, and the lifting limiting altitude that goes up of hoisting crane increases.
The end carriage two ends of lifting are installed and are stablized roller, stablizing roller contacts with the lower surface of track, when electric block moves to the end of girder, being stablized roller limits, the running roller of the drive roller wheel device on the electric block end carriage far away can perk, so increase the working stability of hoisting crane, eliminated potential safety hazard.
The girder of hoisting crane and the two ends of suspended rail are equipped with limit switch, can limit the operational limit position of electric block.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a birds-eye view of the present utility model;
Fig. 3 is the structural representation of end carriage in the utility model.
Among the figure: 1, girder; 2, electric block; 3, drive roller wheel device; 3-1, running roller; 3-2, drive motor; 4, end carriage; 5, stablize roller; 6, suspended rail; 7, limit switch.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2 and Fig. 3, a kind of twin beams overhang crane, comprise two girders that are parallel to each other 1 and electric block 2, the transversal surface of described girder 1 is an I-shape construction, electric block 2 is installed on two girders 1 by drive roller wheel device 3, drive roller wheel device 3 comprises running roller 3-1 and drive motor 3-2, drive motor 3-2 is connected with running roller 3-1, drive motor 3-2 drive roller wheel 3-1 rotates, running roller 3-1 is that double-tee girder 1 rolls for track with the transversal surface, realizes the left and right sides side travel of electric block 2 with this.Connect two end carriages 4 on two girders 1, the middle part of end carriage 4 is a concave structure, two girders 1 by bolted connection on the spill position of end carriage 4, two end carriages 4 and two girders, 1 formation groined type structures.Be provided with drive roller wheel device 3 and stable roller 5 near its two ends on the end carriage 4, end carriage 4 is installed on the suspended rail 6 by drive roller wheel device 3 and stable roller 5, the transversal surface of suspended rail 6 is an I-shape construction, running roller 3-1 is to roll on the double-tee suspended rail 6 at transversal surface, vertically move with these front and back of realizing electric block 2, stablizing roller 5 contacts with the lower surface of suspended rail 6, when electric block 2 moves to the end of girder 1, stablized roller 5 restrictions, the running roller 3-1 of the drive roller wheel device 3 on electric block 2 end carriage 4 far away can perk, increase the working stability of hoisting crane, eliminated potential safety hazard.The girder 1 of above-mentioned hoisting crane and the two ends of suspended rail 6 are equipped with limit switch 7, can limit the operational limit position of electric block.
