Though the single truss arm that prior art adopts can reach certain lifting purpose, its jib poor stability in plane of rotation, transportation receives severely restricts for the ultra-large type crane transition.Therefore, be necessary to provide a kind of truss arm rational in infrastructure and truss jib crane.
The utility model content
Be the technical matters of the jib poor stability of single truss arm in plane of rotation that solve prior art, the utility model provides a kind of truss arm and truss jib crane, and it can improve jib stability in the plane of rotation.
The utility model provides a kind of truss arm, and this truss arm comprises: first tie-beam; Two middle segmentum intercalaris arms, an end of two middle segmentum intercalaris arms is connected on first tie-beam with removably respectively; Second tie-beam, the width of second tie-beam are less than first tie-beam, and the other end of two middle segmentum intercalaris arms is connected on second tie-beam with removably respectively; Two coxopodite arms, two coxopodite arms comprise a fixed end and a free end respectively, first tie-beam is connected with the free end of two coxopodite arms respectively; The epimerite arm, an end of epimerite arm is connected on second tie-beam with removably.
According to a preferred embodiment of the utility model, first tie-beam is formed by connecting with removably at least two first tie-beam unit.
According to a preferred embodiment of the utility model, two middle segmentum intercalaris arms are formed by connecting with removably at least two middle segmentum intercalaris arm units respectively.
According to a preferred embodiment of the utility model, two middle segmentum intercalaris arms are symmetrical set with respect to the line of centers of first tie-beam.
According to a preferred embodiment of the utility model, two middle segmentum intercalaris arms and two coxopodite arms are connected to the relative both sides of first tie-beam.
According to a preferred embodiment of the utility model, two middle segmentum intercalaris arms and two coxopodite arms are connected to the end of first tie-beam.
According to a preferred embodiment of the utility model, two middle segmentum intercalaris arms and two epimerite arms are connected to the relative both sides of second tie-beam.
The utility model also provides a kind of truss jib crane, and this truss jib crane comprises the truss arm of the utility model.
Be different from the situation of prior art, truss arm of the utility model and truss jib crane can improve the jib stability in the plane of rotation, and upgrade the overall operation ability of heavy-duty machine, have improved the problem of transition transportation restriction behind the ultra-large type hoisting crane truss.
Description of drawings
Fig. 1 is the structural representation of the truss arm of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Fig. 1 is the structural representation of the truss arm of the utility model embodiment.As shown in Figure 1, the truss arm of the utility model one preferred embodiment comprises: the middle segmentum intercalaris arm of first tie-beam 10, two 20, second tie-beam 30, two coxopodite arms 40 and two epimerite arms 50.
Wherein, first tie-beam 10 is formed by connecting with removably at least two first tie-beam unit 11.The length of first tie-beam 10 can be regulated through the number that increases or reduce the first tie-beam unit 11, to satisfy the needs of different places and lifting.
The width of second tie-beam 30 is less than first tie-beam 10.
One end of two middle segmentum intercalaris arms 20 is connected on first tie-beam 10 with removably respectively.The other end of two middle segmentum intercalaris arms 20 is then drawn close each other, and the other end of two middle segmentum intercalaris arms 20 is connected on second tie-beam 30 with removably respectively.Two middle segmentum intercalaris arms 20 are symmetrical set with respect to the line of centers of first tie-beam 10.Two middle segmentum intercalaris arms 20 are formed by connecting with removably at least two middle segmentum intercalaris arm units 21 respectively.The length of middle segmentum intercalaris arm 20 can be regulated through the number of segmentum intercalaris arm unit 21 in increasing or reducing, and makes jib combination variation more, thereby satisfies the different hoisting heights and the requirement of amplitude better.
Two coxopodite arms 40 comprise a fixed end and a free end respectively, and first tie-beam 10 is connected with the free end of two coxopodite arms respectively.Two coxopodite arms 40 and two middle segmentum intercalaris arms 20 are connected to the relative both sides of first tie-beam 10.Two middle segmentum intercalaris arms 20 and two coxopodite arms 40 are connected to the end of first tie-beam 10.
One end of epimerite arm 50 is connected on second tie-beam 30 with removably.Two middle segmentum intercalaris arms 20 and two epimerite arms 50 are connected to the relative both sides of second tie-beam 30.
Because the truss arm has at the bigger loading characteristic of jib root place deflection, the utility model truss arm adopts the narrow A font combination of the wide arm head in bottom, and can change the beginning size of 40 two arms of coxopodite arm through the length of regulating first tie-beam 10.The closer to coxopodite arm 40 places, the distance between two middle segmentum intercalaris arms 20 is wide more, and the truss arm is then good more at the plane of rotation internal stability, thereby has greatly improved the jib low side stressing conditions of truss arm, has improved the jib resistance to overturning of truss arm in plane of rotation.
The utility model also provides a kind of truss jib crane, and this truss jib crane comprises above-mentioned truss arm, and the truss arm that the structure of the truss arm of this truss jib crane and technical characterictic please refer to the utility model is described, and repeats no more here.
Be different from the situation of prior art, truss arm of the utility model and truss jib crane can improve the jib stability in the plane of rotation, and upgrade the overall operation ability of heavy-duty machine, have improved the problem of transition transportation restriction behind the ultra-large type hoisting crane truss.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
