Detailed description of the invention
For the ease of understanding the utility model, hereafter will do to describe more comprehensively, meticulously to the utility model in conjunction with Figure of description and preferred embodiment, but protection domain of the present utility model is not limited to following specific embodiment.
It should be noted that, when a certain element is described on " be fixed on, be fixed in, be connected to or be communicated in " another element, it can be directly fixing, affixed, connect or be communicated with on another element, also can be by other intermediate connectors indirectly fixing, affixed, connection or connection on another element.
Unless otherwise defined, hereinafter used all technical terms are identical with the implication that those skilled in the art understand usually.The object of technical term used herein just in order to describe specific embodiment is not be intended to limit protection domain of the present utility model.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, extension mast 3 in the present embodiment comprises the first flexible mast 9, the second fixing mast 10 and the retractable driving device 11 be arranged at outside mast, first mast 9 bottom is provided with a gear fixed connection point, be the first mast point of connection 14, second mast 10 is sleeved in the first mast 9, second mast 10 is provided with two gear fixed connection points, be respectively the first fixed connection point 15 and the second fixed connection point 16, retractable driving device 11 by first install hinge 12 and second install hinge 13 respectively with the first mast 9 and the second mast 10 hinged.Retractable driving device 11 realizes the first mast 9 by Telescopic and the second mast 10 relative position changes, be fixed on the first fixed connection point 15 place of the second mast 10 by attaching parts after first mast 9 stretches out, be fixed on the second fixed connection point 16 place of the second mast 10 by attaching parts after first mast 9 retraction, thus realizing the adjustment of mast absolute length, it connects reliable.Wherein, retractable driving device 11 can according to engineering machinery vehicle provide propulsion source form difference adapt to configuration, be specifically as follows oil hydraulic cylinder or air cylinder.Current large-scale engineering machinery vehicle does propulsion source mainly with hydraulic efficiency pressure system, so use hydraulic ram as retractable driving device 11 in a preferred embodiment.
In the present embodiment, the first mast point of connection 14, first fixed connection point 15 and the second fixed connection point 16 are pin-and-hole, and attaching parts is bearing pin.Certainly, the connection mode of the first mast 9 and the second mast 10 is not only limited to the form of pinned connection yet, can also be hinge type connection or the connection of riveting hydrant etc., understand in scope, will not enumerate here those skilled in the art.
In addition, on second mast 10 except being provided with the first fixed connection point 15 and the second fixed connection point 16, more gear fixed connection point also can be set, and the spacing between each gear fixed connection point can equally also can not wait, when the second mast 10 being connected with the first mast 9 by each gear fixed connection point, extension mast 3 length can independent assortment, makes the length optional of mast.When mast extends, meet and long-armedly erect arm requirement, and provide larger hoisting moment when hanging and carrying; After mast is retracted, its absolute length diminishes, and can reduce the transition radius and the transition height that are configured with this mast engineering machinery vehicle, be convenient to engineering machinery vehicle transition walking.
Refer to Fig. 5, Fig. 5 be the utility model engineering machinery vehicle in running order time structural representation, engineering machinery vehicle in the present embodiment comprises vehicle body 1, variable amplitude rope 2, hoist rope 4, arm-tie 5, suspension hook 6, jib 7, mast lifting body 8 and coxopodite arm 17, and is equiped with above-mentioned extension mast of the present utility model 3.
Vehicle body 1 and extension mast 3 bottom (the second mast 10) and the rotatable pivot joint in coxopodite arm 17 bottom, and play the effect of support telescopic formula mast 3 and coxopodite arm 17; Variable amplitude rope 2 is connected with vehicle body 1 respectively at extension mast 3 top (the first mast 9), vehicle body 1 is also provided with mast lifting body 8, mast lifting body 8 other end and extension mast 3 hinged, when needs transition, adjusted the position of extension mast 3 by mast lifting body 8.Wherein, the material of variable amplitude rope 2 can be the tension material that steel wire or other elasticities are good.Arm-tie 5 one end is connected with the top of the first mast 9, and the other end is connected with the coxopodite arm 17 of jib 7 is detachable.When engineering machinery vehicle operation working properly (non-transition process), make extension mast 3 be in full length by retractable driving device 11, between the first mast point of connection 14 of the first mast 9 and the first fixed connection point 15 of the second mast 10, pass through pinned connection.Extension mast 3 pulls jib 7 to change the elevation angle of jib 7 by arm-tie 5, and then changes the lifting altitude of whole engineering machinery vehicle.
It should be noted that, be connected for removable between jib 7 with its coxopodite arm 17, with when needs transition, mast lifting body 8 reduces the height of extension mast 3 in the vertical direction and after being retracted to predetermined length between the first mast 9 and the second mast 10, arm-tie 5 can be connected to lift with coxopodite arm 17 and fix coxopodite arm 17.
As shown in Figure 6, when engineering machinery vehicle transition, make extension mast 3 be in contraction state, between the first mast point of connection 14 of the first mast 9 and the second fixed connection point 16 of the second mast 10, pass through pinned connection.Method is: first put down jib 7, removes arm-tie 5 and the connection of jib 7, removes jib 7, only retain coxopodite arm 17, remove the connection bearing pin be fixed on the first mast point of connection 14 and the first fixed connection point 15, now the first mast 9 and the second mast 10 are in notconnect state, by the effect of retractable driving device 11, first mast 9 is slided relative to the second mast 10 again, be specially retractable driving device 11 and do contractive action, first mast 9 is slidably retractable on the second mast 10, when the first mast point of connection 14 and the second fixed connection point 16 position to time corresponding stop the action of retractable driving device 11, first mast point of connection 14 and the second fixed connection point 16 are fixed with bearing pin, extension mast 3 to appropriate location is adjusted by mast lifting body 8, extension mast 3 is connected with coxopodite arm 17 arm-tie 5, complete transition to prepare.
Hoist rope 4 one end is connected with vehicle body 1, and the other end is by the apical support connecting shackle 6 of jib 7.In addition, the connection structure between the present embodiment arm-tie 5 and jib 7 and working process, in the scope that the art personnel understand, are not carefully stated.
It should be noted that the engineering machinery vehicle of the present embodiment can be crawler type or other forms of hoisting crane.
After mast is folding, change the absolute length of himself, lift by arm-tie is stable and fixes coxopodite arm position, efficiently reduce transition height and the transition radius of engineering machinery vehicle, eliminate prior art by compared with the algorithm will dismantling coxopodite arm during low obstacle, save work-hours, improve transition efficiency.
The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively in detail concrete, but therefore can not be interpreted as the restriction to utility model patent scope.When it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
