Abstract
The front supporting layer-tonnage crawling crane is characterized by that its front cylinder hinge and rear cylinder hinge are respectively mounted on the lazyarm and revolving body, its front cylinder is respectively connected with front cylinder hinge and base plate, one end of rear cylinder is connected with rear cylinder hinge, its another end is connected with hinge placed on the base plate, and the base plate is connected with supporting plate. Before the body is lifted by lift hook, the rear cylinder is opened, the supporting plate is connected with ground surface, at the same time the front cylinder and hoister are started, at the moment the weight of lifted body is heavier than original structure.
Description
The present invention relates to be used in the engineering crawler crane of Transhipment Cargo.
Existing crawler crane in actual use, because of arm is done longly, when object was hung with horizontal sextant angle is less in arm elongation back, the angle of front steel rope and level was less, changeing the machine of raising needs arm and object to be sling with very big power, and it is smaller therefore to hang weight of object.
Purpose of the present invention just provides a kind of front supported large tonnage crawler crane.
For reaching this purpose, the main technical schemes of front supported large tonnage crawler crane of the present invention is: add the supporting position under arm, make hoisting crane after suspension hook is sling object, this supporting and commentaries on classics are raised machine and are worked simultaneously, thereby increase the weight of slinging object.According to the present invention, arm links by hinge and gyro-rotor, and suspension hook and front wheel are positioned on the arm front end, and on the frame, middle by front wheel, the other end and commentaries on classics were raised machine and linked during front steel rope one end was fixed on; Commentaries on classics is raised machine and is positioned on the gyro-rotor; In be equipped with fixed pulley on the frame, rear steel rope is on the fixed pulley and after-frame fixed pulley of middle frame, after-frame connects for cutting with scissors with putting on the shelf, putting on the shelf is fixed on the gyro-rotor, gyro-rotor can rotate around car body, car body is positioned on the crawler belt body.Oil cylinder hinge before being equipped with on the arm, preceding oil cylinder one end and preceding oil cylinder hinge link, and the hinge on the other end and the base plate links; Back oil cylinder hinge is positioned on the gyro-rotor, and back oil cylinder one end links with back oil cylinder hinge, and the hinge on the other end and the base plate links; The base plate bottom has a spheroid and back plate to link.Preceding oil cylinder can rotate around arm and base plate, and back oil cylinder can be turned and the base plate rotation in wraparound, and base plate can rotate around back plate.
After adopting this structure, before hoisting crane is sling object, back oil cylinder supporting is opened, back plate is contacted with ground, object is sling with suspension hook, preceding oil cylinder and commentaries on classics are raised machine and are started simultaneously, arm and object are retracted, regain forward and backward oil cylinder, at this moment very big because of arm and horizontal sextant angle, commentaries on classics is raised machine and can be worked independently, and rotates gyro-rotor to desired location.After adding the supporting position, hanging object weight increases, and simultaneously, the supporting position is not recoverable to when not working, and is simple in structure, working stability.
Fig. 1 is the working condition figure of front supported large tonnage crawler crane of the present invention.
Fig. 2 be Fig. 1 to view.
Fig. 3 is the part base plate 16 of front supported large tonnage crawler crane of the present invention and the assembly drowing of back plate 15 for figure, also is the cutaway view of Fig. 4.
Fig. 4 is the part base plate 16 of front supported large tonnage crawler crane of the present invention and the assembly drowing of back plate 15.
Fig. 5 is that the part of Fig. 3 is to view.
Below by concrete embodiment and accompanying drawing front supported large tonnage crawler crane of the present invention is described further.
The front supported large tonnage crawler crane of Fig. 1, arm 1 links with gyro-rotor 8 by cutting with scissors 12, suspension hook 19 and front wheel 2 are positioned on the front end of arm 1, front steel rope 3 one ends are fixed on the middle frame 4, middle by front wheel 2, the other end and commentaries on classics are raised machine 10 and are linked, commentaries on classics is raised machine 10 and is positioned on the gyro-rotor 8, be equipped with fixed pulley on the middle frame 4, rear steel rope 5 on the fixed pulley of the fixed pulley of middle frame 4 and after-frame 6, after-frame 6 with put 7 on the shelf for hinge connects, putting on the shelf 7 is fixed on the gyro-rotor 8, gyro-rotor 8 can rotate around car body 9, and car body 9 is installed on the crawler belt body 13; Oil cylinder hinge 18 before being equipped with on the arm 1, preceding oil cylinder 17 1 ends and preceding oil cylinder hinge 18 link, and the hinge on the other end and the base plate 16 links, and back oil cylinder hinge 11 is positioned on the gyro-rotor 8, and back oil cylinder 14 1 ends link with back oil cylinder hinge 11, and the hinge on the other end and the base plate 16 links; Can see that from Fig. 3 to Fig. 5 base plate 16 bottoms have a spheroid and back plate 15 to link, back plate 15 is made up of polylith plate and attachment bolt.
