In the foldable cantilever beam, the connecting rods and the cantilever ginpole are used to externally strengthen main bearing parts, so that the load lifting capability of the cantilever crane can be further enhanced on the premise of no dead weight increase of the cantilever crane, and the cantilever crane is foldable on the basis of the original functions; and the foldable cantilever crane has strong field applicability and meets the operation requirement for small-tonnage hoisting operation.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of folding cantilever and hangs.
Background technology
Platform loop wheel machine and all kinds of ocean engineering boats and ships loop wheel machine, it is the major equipment of marine oil engineering and ocean engineering, main weight-lifting equipment as marine operation should have higher reliability and security requirement, so the routine inspection of equipment and maintenance just seem particularly important.Usually need to carry out little tonnage hoisting operation in the routine inspection of power plant is safeguarded, existing cantilever hangs the installation site and fixes, the lifting limited coverage area, and install, transportation inconvenience, problem such as it is heavier to conduct oneself with dignity.
Summary of the invention
The purpose of this utility model provides a kind of folding cantilever and hangs, and has solved to have the lifting limited coverage area in the prior art, and has installed, transports inconvenience, the heavier problem of deadweight.
The technical scheme that the utility model adopted is, a kind of folding cantilever hangs, on pedestal, be installed with column spinner, the column spinner upper end is equipped with lower bracket, the lower bracket upper end is equipped with upper bracket, cantilever beam is installed on the upper bracket, and cantilever beam and pipe link, gin pole constitute the triangle connection structure, and lower bracket, upper bracket, gin pole and another section pipe link constitute another triangle connection structure; The slip crane is installed on the slide rail of cantilever beam, and the slip crane is realized being connected by control path with motor driver, and the slip crane is connected with the loop chain cucurbit downwards.
The beneficial effects of the utility model are, possess the ability of the load that promotes certain tonnage under lighter deadweight, and possess rotatable, folding characteristics, install, convenient transportation, have improved work efficiency.
Description of drawings
Fig. 1 is the structural representation that the utility model folding cantilever hangs;
Fig. 2 is the partial folds view that the utility model folding cantilever hangs.
Among the figure, 1. lower bracket, 2. upper bracket, 3. cantilever beam, 4. slip crane, 5. pipe link, 6. gin pole, 7. column spinner, 8. loop chain cucurbit, 9. bearing pin safety pin, 10. spacer, 11. motor drivers, 12. pedestals, 13. backing pin mounting holes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
With reference to Fig. 1, the structure that the utility model folding cantilever hangs is, on pedestal 12, be installed with column spinner 7, column spinner 7 upper ends are equipped with lower bracket 1, lower bracket 1 upper end is equipped with upper bracket 2, cantilever beam 3 is installed on the upper bracket 2, and cantilever beam 3 constitutes the triangle connection structure with pipe link 5, gin pole 6, and lower bracket 1, upper bracket 2, gin pole 6 and another section pipe link 5 constitute another triangle connection structure; On the unsettled end of cantilever beam 3 spacer 10 is installed, slip crane 4 is installed on the slide rail of cantilever beam 3, slip crane 4 is realized being connected by control path with motor driver 11, and slip crane 4 is connected with loop chain cucurbit 8 downwards.
With reference to Fig. 2, all realize connecting between lower bracket 1, upper bracket 2, cantilever beam 3, pipe link 5, gin pole 6, the column spinner 7 by each bearing pin safety pin 9, when taking each bearing pin safety pin 9 apart, realize folding.
This folding cantilever hangs that to be provided with the many places lift heavy spacing, because the maximum when cantilever is hung in diverse location allows the hoisting capacity difference, so this folding cantilever is hung in cantilever beam 3 and is provided with backing pin mounting hole 13, insert backing pin at diverse location and can limit the maximum that cantilever is hung in the different range and allow hoisting capacity.
Between cantilever beam 3 and gin pole 6, lower bracket 1 and gin pole 6, adopted the structure of the pipe link 5 of double joint.The spacer 10 of packing between the pipe link 5 prevents that pipe link from collecting together.Pipe link 5 can use steel rope interconnection system structure, also can adopt the steel plate battened construction.
Adopt the outer structure of strengthening to improve the integrated carrying ability, cantilever beam 3 is installed in upper bracket 2 places, by bearing pin safety pin 9 pipe link 5, gin pole 6 are connected with the lower bracket bottom with the cantilever beam end respectively, wherein pipe link 5 is to bear pulling force, gin pole 6 is to bear pressure, and actv. has increased the stability and the whole resistance to bending of cantilever beam of cantilever beam.
The assembling process of the utility model device is, earlier slip crane 4 is loaded on the cantilever beam 3, cantilever beam 3, pipe link 5, gin pole 6 are connected with upper bracket 2 firmly by each bearing pin safety pin 9, upper bracket 2, pipe link 5, gin pole 6 are connected with lower bracket 1 firmly by other bearing pin safety pin 9; Then column spinner 7 is installed on the permanent seat 12, at last lower bracket 1 is connected with column spinner 7.After weight was sling by loop chain cucurbit 8, the movement of weight drives slip crane 4 by motor driver 11 rotatings pulling steel rope and finishes, and was time saving and energy saving.
The revolution that the folding cantilever hangs realizes that by the static friction bearing and the column spinner 7 at fixed position place column spinner 7 is enclosed within the place, fixed position of packing in the static friction bearing, guarantees that cantilever is hung in when bearing bearable load can normally turn round.Cantilever hangs and can connect directly use of back at other design attitude places, has increased the lifting scope of work that cantilever hangs to a certain extent, has saved cost.In when transportation, can direct independent member after the binding bolt of column spinner 7 bottoms comes loose, be convenient to transportation.
The utility model device, by pipe link and gin pole main load bearing component has been carried out outer reinforcement, optimized the strained condition of each parts, further increase cantilever under the situation that cantilever hangs deadweight and hang the ability that promotes load not increasing, cantilever is hung on the basis of original function possesses folding function, on-the-spot applicability is strong, when the routine inspection that satisfies platform loop wheel machine and all kinds of ocean engineering boats and ships loop wheel machine equipment is safeguarded, carries out the operation requirements of little tonnage hoisting operation.
