Description
Technical field
The utility model is used for the swingable extendable weight structure of locomotive crane, belongs to crane field, particularly locomotive crane.
Background technology
Rail vehicles topples and derailment accident, mostly occur in its travel track on or its adjacent place single track railway on, broken-down vehicle and wrecking crane exist together on a track; On double track railway, circuit is traffic interruptions because of accident, must ensure the unimpeded of adjacent lines with all strength, and wrecking crane should make every effort to, not affecting under the prerequisite that adjacent line normally runs, the circuit interrupted complete rescue work.Therefore, within the scope of straight rail direction ± 30 °, there is larger load-carrying ability, significant to railway breakdown operation.
When locomotive crane operation, in order to make locomotive crane have enough lift heavy stability against overturning, the balance weight of the line turntable afterbody configuration certain mass farthest that often topples in distance.Traditional rotating platform of crane afterbody balance weight tail radius in lift heavy process remains constant.Therefore, if larger to the designing requirement of the maximum hoisting moment value of hoisting crane, so its tail radius often has to corresponding increasing when designing, and this just makes the structure of turntable increase accordingly.For avoid locomotive crane when turning round on the side slope of turntable afterbody and cutting bump against, or during in order to crane rotation, afterbody does not invade the gauge of adjacent line, ensures the safe and smooth of adjacent line, has strict requirement to turntable tail radius.In view of user is to the strict demand of lifting performance and tail radius, telescopic tail balance weight is adopted to seem extremely important.Prior art will realize four joint arms and stretch, substantially be adopt two schemes: the first is that telescopic oil cylinder adds rope row formula structure, this structure is larger to arm internal space requirements, and locomotive crane has very strict requirement to gauge, telescopic arm structure is less, and telescopic oil cylinder adds rope row formula can not be applied to counter weight construction; First scheme adopts single-cylinder plug pin formula structure, and this mode structure is more complicated, and requires higher to control system.
The extendable weight of current employing mainly contains two kinds of versions, the first is that extendable weight and upper turntable together turn round, in pivotal process, upper turntable center and telescopic boom center overlap all the time, this satisfies the antidumping performance that hoisting moment increases, however within the scope of straight rail ± 30 ° during operation counterweight still can affect adjacent line and normally run; Second method is that the upper frame part of hoisting crane is provided with upper and lower two turntables, be placed on two cover pivoting supports respectively, extendable weight is connected on lower turntable, instantly when rotating platform lock fixes on underframe longitudinal centerline, upper turntable independently can do the revolution operation within the scope of straight rail ± 30 °, the flexible normal operation not affecting adjacent line all the time of counterweight, the rotatable extendable weight complex structure of this double back, weight is large, and cost is high, have impact on its application.
Utility model content
The utility model object is to provide a kind of swingable extendable weight structure for locomotive crane, flexible and the revolution by oil cylinder, weight arm is made not only to meet the requirement of the antidumping performance of the large hoisting moment of locomotive crane, and the relative turntable of weight arm can be made to make reversed turning be straight rail direction, do not disturb the operation of adjacent line train.
