Abstract
The utility model discloses a jib crane, including the cantilever of fixed part and level setting, the fixed part is fixed on vertical wall body or cylinder, and the cantilever includes little cantilever and big cantilever, big cantilever one end is rotated with the fixed part and is connected, little cantilever one end is connected with the other end rotation of big cantilever, and the little cantilever other end is provided with rings, can carry out 360 rotatory little cantilevers around big cantilever through setting up, when the range limit value is lifted by crane in the increase, the lower limit value of the reduction scope of lifting by crane for the scope of lifting by crane more greatly, more nimble, more have the practicality.
Description
Technical field
This utility model relates to hoisting machinery field, particularly relates to a kind of cantilever crane.
Background technology
Existing cantilever crane includes stand and horizontally disposed cantilever beam, cantilever beam can carry out 180 degree horizontally rotate around the center of rotation with stand, at cantilever beam-ends, electric block is installed, the process that cantilever beam rotates is realized the handling of associated workpiece by electric block, this cantilever crane there is a problem in that lifting scope is little, although lifting scope can be extended by changing the length of cantilever beam, but the effect realized is the higher limit increasing lifting scope, and cannot increase lifting scope by the lower limit of reduction lifting scope.
In view of the defect that above-mentioned existing cantilever crane exists, the present inventor is based on being engaged in this type of product engineering application practical experience abundant for many years and Professional knowledge, and coordinates the utilization of scientific principle, actively in addition research and innovation, to founding a kind of cantilever crane so that it is have more practicality.
Utility model content
This utility model provides a kind of cantilever crane, 360 ° of little cantilevers rotated can be carried out around great cantilever one end by setting up, while increasing lifting range higher limit, reduce the lower limit of lifting scope, make lifting scope bigger, more flexible, thus having more practicality.
The technical scheme that this utility model is taked is: a kind of cantilever crane, and including fixed part and horizontally disposed cantilever, fixed part is fixed on vertical body of wall or cylinder,
Cantilever includes little cantilever and great cantilever；
Great cantilever one end and fixed part are rotationally connected；
The other end of little cantilever one end and great cantilever is rotationally connected, and the little cantilever other end is provided with suspension ring.
Further, the length of little cantilever is less than the length of great cantilever.
Further, little cantilever is arranged at below great cantilever.
Further, great cantilever bottom and little cantilever top are correspondingly arranged on fixing hole, and when little cantilever and great cantilever angle are 0 °, the fixing hole laying respectively at great cantilever bottom and little cantilever top overlaps.
Further, it is provided with reinforcement bottom great cantilever and the junction of fixed part.
Further, cantilever crane also includes electric block, and electric block and suspension ring removably connect.
After have employed technique scheme, this utility model has following beneficial effect:
1, by setting up and can carry out 360 ° of little cantilevers rotated around great cantilever, rotation with the 180 of great cantilever ° can arbitrarily be combined, and while increasing lifting range limit, reduces the lower limit of lifting scope, make lifting scope bigger, more flexible, thus having more practicality；
2, by changing the length difference of great cantilever and little cantilever, the higher limit of lifting scope and lower limit can be adjusted, and be easily achieved；
3, by being correspondingly arranged on fixing hole in great cantilever bottom and little cantilever top, when fixing hole can be fixed by bolt and nut after overlapping, it is prevented that cantilever crane arbitrarily rotates when not working；
4, because great cantilever and the top, junction of fixed part are relatively big by pulling force, therefore arranging reinforcement in bottom can increase both bonding strengths, it is ensured that the personal safety of operator；
5, electric block and cantilever are removably connected by suspension ring, it is simple to the selection of electric block model and replacing.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, obviously, the accompanying drawing that the following describes is only some embodiments recorded in this utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of cantilever crane of the present utility model；
Fig. 2 is the top view of Fig. 1；
Labelling implication in accompanying drawing: 1 fixed part, 2 cantilevers, 21 little cantilevers, 22 great cantilever, 23 suspension ring, 24 fixing holes, 25 reinforcements, 3 electric blocks.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical scheme in this utility model, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of this utility model protection.
This utility model embodiment adopts the mode gone forward one by one to write.
As described in Fig. 1 and 2, a kind of cantilever crane, including fixed part 1 and horizontally disposed cantilever 2, fixed part 1 is fixed on vertical body of wall or cylinder, and wherein cantilever 2 includes little cantilever 21 and great cantilever 22；Great cantilever 22 one end and fixed part 1 are rotatably connected；Little cantilever 21 one end and great cantilever 22 are rotationally connected, and little cantilever 21 other end is provided with suspension ring 23；Can carrying out 360 ° of little cantilevers 21 rotated around great cantilever 22 by setting up, the rotation with the 180 of great cantilever 22 ° can arbitrarily be combined, and while increasing the higher limit of lifting scope, reduces the lower limit of lifting scope so that lifting scope is bigger, more flexible.
The length of little cantilever 21 is less than the length of great cantilever 22, by changing the length difference of great cantilever 22 and little cantilever 21, the higher limit of lifting scope and lower limit can be adjusted, and be easily achieved；Great cantilever 22 bottom and little cantilever 21 top are correspondingly arranged on fixing hole 24, when little cantilever 21 is 0 ° with great cantilever 22 angle, the fixing hole 24 laying respectively at great cantilever 22 bottom and little cantilever 21 top overlaps, by being correspondingly arranged on fixing hole 24 in great cantilever 22 bottom and little cantilever 21 top, when fixing hole 24 overlap after can be fixed by bolt and nut, it is prevented that cantilever crane when not working with rotation；Being provided with reinforcement 25 bottom great cantilever 22 and the junction of fixed part 1, because great cantilever 22 and the top, junction of fixed part 1 are relatively big by pulling force, therefore arranging reinforcement 25 in bottom can increase both bonding strengths, it is ensured that the personal safety of operator；Underhung crane in the present embodiment also includes electric block 3, and electric block 3 and suspension ring 23 removably connect, compared with fixed suspension hook, it is simple to the selection of electric block model and replacing.
