Description of drawings
Fig. 1 is a kind of typical truss arm upset work sketch map in the prior art;
Fig. 2 provides the structural representation of a kind of specific embodiment of truss arm positioner for the utility model.
The specific embodiment
The core of the utility model provides a kind of truss arm positioner, the upset floor space in the time of effectively reducing the welding of truss arm, and improve upset efficient.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with the accompanying drawing and the specific embodiment.
Please refer to Fig. 2, Fig. 2 provides the structural representation of a kind of specific embodiment of truss arm positioner for the utility model.
The truss arm positioner that the utility model provided; Comprise base 21, two support arms 22 and driving wheels 23 being fixedly connected with base 21, drive the power part that this driving wheel 23 rotates; And the flexible support chain 24 of sub-truss arm 3; Be fixedly connected with first support wheel 25 and second support wheel 26 on two support arms respectively; Be fixedly connected with the 3rd support wheel 27 on the base 21, the flexible support chain is 24 end to end, walk around driving wheel 23 successively, first support wheel 25, second support wheel 26 and the 3rd support wheel 27.
During welded truss arm 3; A side of truss arm 3 is placed on the base 21, after the welding of this side is accomplished, utilize driving wheel 23 to drive flexible support chains 24 and move along first support wheel 25, second support wheel 26 and the 3rd support wheel 27; And then drive is by the truss arm 3 of flexible support chain 24 supports; The side that truss arm 3 and base 21 are fitted tilts gradually, revolves along an one of which summit, cross section until truss arm 3 to turn 90 degrees, and the another side of truss arm 3 and flexible support chain 24 are fitted; Then fit with base 21, can weld new side.
This switching process is steady, and efficient is high, and truss arm 3 has certain flexibility under the support of flexible support chain 24, and reliability is higher.Simultaneously, the horizontal floor space of this positioner is less, and space availability ratio is high, and use is more flexible.
Particularly, the length of flexible roller chain greater than between the twice of support arm 22 length and two support arms 22 apart from sum.Be support arm 22 height the most in short-term, the partially flexible roller chain can directly be placed on the base 21, rather than vacant state, and the truss arm 3 that is supported by the flexible roller chain directly is placed on the base 21, and is steady when keeping welding, improves welding efficiency.
In a kind of concrete embodiment; Support arm 22 comprises fixed arm 221 and is supported and can be along the flexible telescopic arm 222 of its bearing of trend by fixed arm 221; Fixed arm 221 is fixedly connected with base 21, and first support wheel 25 and second support wheel 26 are fixed in respectively on two telescopic arms 222.Truss arm 3 if truss arm 3 all the time on base 21, produces and clashes into easily with between the base 21 in the rotation process, influences the quality of truss arm 3 in switching process.Therefore, can when welding support arm 22 height lower, truss arm 3 can directly be positioned on the base 21; When needs overturn, utilize flexible support chain 24 that truss arm 3 is sling, make truss arm 3 in switching process and 21 of bases keep the certain height distance, airborne when guaranteeing 3 upsets of truss arm, bump and between the base 21.
Like this, highly adjustable support arm 22 can meet the demands.And to the truss arm 3 of different size, its size is different.Support arm 22 is designed to adjustable for height two joint arms; Can be according to the size of truss arm 3, the height of adjustable support arm 22 makes the adjustable height of the bottom of flexible support chain 24 with respect to base 21; The truss arm 3 of different size all can leave base 21 under the support of flexible support chain 24; Realize upset aloft, thereby avoid truss arm 3 in rotation process, to occur damaging, like this; This positioner can satisfy the welding demand of the truss arm 3 of multiple different model, thereby improves the applicability of positioner that the utility model provides.
Obviously, if the height of support arm 22 is non-adjustable, utilize flexible support chain 24 also can realize the upset of truss arm 3, its switching process also can held stationary, and floor space is also less, does not influence the purpose that realizes the utility model.Therefore, the highly nonadjustable positioner of support arm 22 also should be within the protection domain of the utility model.
Further, the positioner that the utility model provided also comprises the actuator cylinder 28 that connects fixed arm 221 and telescopic arm 222, and the cylinder barrel of this actuator cylinder 28 is fixedly connected with fixed arm 221 with the cylinder bar, and another person is fixedly connected with telescopic arm 222.When the height of support arm 22 need be adjusted, the cylinder bar of actuator cylinder 28 stretched out from cylinder barrel, drove the telescopic arm 222 that is fixedly connected with it or support cylinder barrel to drive telescopic arm 222, telescopic arm 222 was moved, the length of adjustable support arm 22 with respect to fixed arm 221.Actuator cylinder 28 is simple in structure, is easy to realize, can reduce the realization difficulty of support arm 22.And, can utilize synchronous valve that the hydraulic oil of two support arms 22 is kept synchronously, two support arms 22 are stretched out simultaneously or withdraw, regulate the efficient height, controllability is better.
Need to prove, utilize actuator cylinder 28 to realize that telescopic arm 222 is with respect to one of fixed arm 221 flexible just adjustable support arms 22 some means highly.The object that need adjust for two relative positions; Its regulative mode has a variety of; The mode that for example can use slotted hole to cooperate with bolt; The mode that also can use the bolt hole of a plurality of continuous settings to cooperate with bolt, these methods may be used to the relative position adjustment between the fixed arm 221 and telescopic arm 222 in the utility model, realize the purpose of adjustable support arm 22 height.And, regulate simultaneously for two support arms 22, can utilize connecting rod that two telescopic arms 222 are linked together, when regulating a telescopic arm 222, drive another telescopic arm 222 simultaneously.Should be appreciated that above-mentioned various control methods can both satisfy the purpose of the utility model, all should be within the protection domain of the utility model.
In a kind of concrete embodiment, above-mentioned flexible support chain 24 can be the flexible roller chain, and roller chain is a kind of simple; Reliably, power transmission can effectively drive truss arm 3 and move efficiently; Surpass the lower end point of truss arm 3 until the center of gravity of truss arm 3, truss arm 3 is realized upset.And the roller chain reliable in structure, be easy to buying, can reduce the difficulty that realizes positioner.
Particularly, the number of flexible roller chain can be two, and two flexible roller chains are the two ends of sub-truss arm 3 respectively.Truss arm 3 has certain length; The flexible roller chain is along the circumferential sub-truss arm 3 of truss arm 3; Two ends with two flexible roller chains difference sub-truss arms 3; Can guarantee to keep balance when truss arm 3 leaves base 21 ability safety and steady when making 3 upsets of truss arm, the security reliability when improving upset.
Obviously, guarantee truss arm 3 held stationaries, the telescopic arm 222 that also need support two flexible roller chains can stretch out or withdraw simultaneously, makes the height of two support arms 22 keep identical.And the flexible roller chain also can be three or more a plurality of, and each flexible roller chain can be along the even sub-truss arm 3 of the bearing of trend of truss arm 3.
More than the truss arm positioner that the utility model provided has been carried out detailed introduction.Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
