Abstract
The utility model discloses an electric tracked double-jib portal jib crane, which comprises hoisting mechanisms, a rotating mechanism and a traveling mechanism, two groups of luffing four-bar linkage mechanisms are mounted on the rotating mechanism, the horizontal included angle between the two groups of four-bar linkage mechanisms is 180 degrees, and the two groups of four-bar linkage mechanisms are arranged symmetrically, and are respectively provided with an independent hoisting mechanism. The portal jib crane has the following outstanding advantages: since the portal jib crane is provided with the two groups of luffing four-bar linkage mechanisms, the working efficiency of the whole portal jib crane is increased by two times, and the energy consumption per ton is reduced by one third when cargo is loaded or unloaded.
Description
Technical field
The utility model relates to a kind of harbour, logistics handling equipment, and particularly a kind of electric track both arms door machine hangs.
Background technology
It is the visual plant of harbour handling goods that the door machine hangs, and it mainly comprises: lifting mechanism, swing type mechanism and traveling gear, but the inclination single armed frame and the driver's cab of pitching are housed on the swing type mechanism.Traveling gear is arranged on the bottom that a machine hangs, and is the mechanism that is used for mobile entire equipment.This kind door machine hangs only has a single armed frame, can only adorn separately or unloads operation separately, and finish each operation and all need the single armed frame to forward opposite side to from a side-sway, and article are got or put in reposition more afterwards.The mode of operation of this kind structure has limited the work efficiency of equipment greatly, can not satisfy the work rhythm of quickness and high efficiency.
The utility model content
The utility model hangs ineffective defective at single armed frame door machine in the prior art, provides a kind of electric track both arms door machine to hang, and this kind door machine hangs rational in infrastructure, easy and simple to handle.
The utility model at the technical solution that above-mentioned defective adopts is:
Electric track both arms door machine hangs, and comprises lifting mechanism, swing type mechanism and traveling gear, but the four-bar linkage of two groups of pitching is housed on the swing type mechanism, and two groups of four-bar linkage horizontal sextant angles are 180 degree and in a symmetrical arrangement, and are furnished with independently lifting mechanism respectively.
Be in the fan-shaped lifting counterweight of the terminal configuration of push-and-pull rod of rear portion upside in the above-mentioned four-bar linkage.
Above-mentioned swing type mechanism top is provided with trapezoid support, this trapezoid support rigidity of support pull bar.
Above-mentioned trapezoid support inboard is provided with driver's cab.
Above-mentioned swing type mechanism comprises the suspender crossbeam, and the principal arm frame and the suspender crossbeam of four-bar linkage are rotationally connected.
Above-mentioned electric track both arms door machine hangs and also comprises and be positioned at the oil cylinder fixer that a machine hangs the bottom, the oil cylinder fixer has three unidirectional oil cylinders, three unidirectional oil cylinders become " product " font to arrange, what be in the upper end is first oil cylinder, the lower end of first oil cylinder is symmetrical arranged extended end second oil cylinder, the 3rd oil cylinder to the inside, and the oil circuit of second oil cylinder, the 3rd oil cylinder communicates.
The lower end of above-mentioned first oil cylinder is provided with contact lever, has the through hole that the first oil cylinder oil circuit can be communicated with second oil cylinder, the 3rd oil cylinder oil circuit when the contact lever upward movement on the contact lever.
The beneficial effects of the utility model: this electric track both arms door machine hangs, but maximum advantage is to be equipped with the four-bar linkage of two groups of pitching, and the work efficiency of complete machine is doubled, and the ton energy consumption of loading and unloading article descends 1/3rd.In addition, two four-bar linkage symmetric arrangement, counterweight reduces counterweight separately greatly each other, effectively improves complete machine stability.In addition, the door machine hangs the oil cylinder fixer of bottom, and structure design is ingenious, can tightly clamp track, further improves the stability of complete machine when the lifting article.
Description of drawings
The structural representation that Fig. 1 hangs for electric track both arms door machine;
Fig. 2 is the structural representation of oil cylinder fixer.
Below in conjunction with accompanying drawing the utility model is elaborated:
The specific embodiment
In conjunction with Fig. 1, Fig. 2, electric track both arms door machine hangs, and comprises lifting mechanism, swing type mechanism 1 and traveling gear 2, but the four-bar linkage 3 of two groups of pitching is housed on the swing type mechanism 1, two groups of four-bar linkage 3 horizontal sextant angles are 180 degree and in a symmetrical arrangement, and are furnished with independently lifting mechanism respectively.Be in the fan-shaped lifting counterweight 302 of push-and-pull rod 301 terminal configurations of rear portion upside in the four-bar linkage 3.Swing type mechanism 1 comprises suspender crossbeam 101, and the principal arm frame 303 and the suspender crossbeam 101 of four-bar linkage 3 are rotationally connected.Above suspender crossbeam 101, be provided with trapezoid support 4, these trapezoid support 4 rigidity of support pull bars 301.In trapezoid support 4 inboards driver's cab 5 is set.
Electric track both arms door machine hangs and also comprises and be positioned at the oil cylinder fixer 6 that a machine hangs the bottom, oil cylinder fixer 6 has three unidirectional oil cylinders, three unidirectional oil cylinders become " product " font to arrange, what be in the upper end is first oil cylinder 601, the oil circuit that the lower end of first oil cylinder 601 is symmetrical arranged to the inside second oil cylinder 602 of extended end, the 3rd oil cylinder 603, the second oil cylinders 602, the 3rd oil cylinder 603 communicates.Be provided with contact lever 7 in the lower end of first oil cylinder 601, have through hole 701 on the contact lever 7, when contact lever 7 upward movements, through hole 701 can be communicated with first oil cylinder, 601 oil circuits with second oil cylinder 602, the 3rd oil cylinder 603 oil circuits.
Electric track both arms door machine hangs and stands on the track, and the cement concrete of track and its below is with 10 meters dark bolt, and the spacing of each bolt is 30 centimetres.Satisfied the requirement of complete machine to stability.
When electric track both arms door machine hangs work, at first drive complete machine by traveling gear and move to working position, this moment, the first oil cylinder lower ends downward of oil cylinder fixer stretched.Begin upward movement after contact lever is run into rail, the through hole on the contact lever is connected first oil cylinder and second, third oil cylinder oil circuit afterwards, and the extended end of second oil cylinder, the 3rd oil cylinder is stretched out to the inside, tightly clamps rail.After the complete machine fixation, the operating personal in the driver's cab just can be operated two groups of four-bar linkages charge and discharge operations that hockets.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
