Abstract
The utility model discloses a kind of crane main beam structure, comprise cap ned, end carriage, telescopic shaft, connecting panel, fixing screw, inclined-plane, girder plane and girder, described end carriage is fixed by welding in the top of cap ned, described telescopic shaft is enclosed within the top of end carriage, and described girder is fixed on telescopic shaft by fixing screw.This crane main beam structure can adjust the relative height between girder and end carriage, thus change the operation height of hoisting crane, the end carriage of hoisting crane and the junction of girder are provided with a gradient by the field of application expanding hoisting crane, make it smooth transition, ensure to make the overall height of common hoisting crane low when tonnage of driving a vehicle is identical, the corresponding reduction of factory building height, reduces costs; The gradient between end carriage and girder makes dolly smooth transition, and ensure that structural strength structure is simple, stable, cost-saving, applied widely, load-carrying capacity is strong.
Description
Technical field
The utility model relates to the main beam structure technical field of hoisting crane, is specially a kind of crane main beam structure.
Background technology
Hoisting crane is widely used in industrial and mining enterprises, is the requisite lifting appliance of production site.Under being often in extra-heavy state, the intensity of crane girder is the safety of equipment and operating personnel in high guarantee operation process sufficiently.Traditional crane girder and end carriage connect as one usually, and girder is relative with end carriage fixing, and the spacing of cart guide rail and vehicle guide can not be adjusted, thus cause the operation height of hoisting crane to change, and apply limited.Present stage, the girder of crane in bridge type is all adopt high strength bolt, is linked together by master, end carriage connecting panel and end carriage.Due to the restriction of present stage this body structure of girder, hall space is caused to utilize unreasonable.When factory building heights of roofs is certain, support rail depth of beam is certain, has the obstacle or other matching used hoisting cranes that are difficult to get around below hoisting crane, and now need increases lifting altitude to ensure enough handling spaces as far as possible.Therefore how effective and reasonable utilize existing hall space, the lifting altitude how improving hoisting crane in fixing factory building height becomes the target that each hoisting crane producer is pursued.
Utility model content
The purpose of this utility model is to provide a kind of crane main beam structure, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of crane main beam structure, comprise cap ned, end carriage, telescopic shaft, connecting panel, fixing screw, inclined-plane, girder plane and girder, described end carriage is fixed by welding in the top of cap ned, described telescopic shaft is enclosed within the top of end carriage, and described girder is fixed on telescopic shaft by fixing screw.
Preferably, described cap ned is provided with some reinforced ribs.
Preferably, the end of described girder and telescopic shaft junction are provided with a gradient.
Preferably, described girder plane 250 ~ 400mm lower than the upper plane of end carriage.
Preferably, on the inclined-plane on described girder and end carriage, the angle of plane is between 35 ° ~ 55 °.
Preferably, described telescopic shaft moving up and down on end carriage drives moving up and down of girder.
Compared with prior art, the beneficial effects of the utility model are: this crane main beam structure can adjust the relative height between girder and end carriage, thus change the operation height of hoisting crane, the end carriage of hoisting crane and the junction of girder are provided with a gradient by the field of application expanding hoisting crane, make it smooth transition, ensure to make the overall height of common hoisting crane low when tonnage of driving a vehicle is identical, the corresponding reduction of factory building height, reduces costs; The gradient between end carriage and girder makes dolly smooth transition, and ensure that structural strength structure is simple, stable, cost-saving, applied widely, load-carrying capacity is strong.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-cap ned, 2-end carriage, 3-telescopic shaft, 4-connecting panel, 5-fixing screw, 6-inclined-plane, 7-girder plane and 8-girder.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of crane main beam structure, comprise cap ned 1, end carriage 2, telescopic shaft 3, connecting panel 4, fixing screw 5, inclined-plane 6, girder plane 7 and girder 8, described end carriage 2 is fixed by welding in the top of cap ned 1, described cap ned 1 is provided with some reinforced ribs, described telescopic shaft 3 is enclosed within the top of end carriage 2, described girder 8 is fixed on telescopic shaft 3 by fixing screw 5, end and telescopic shaft 3 junction of described girder 8 are provided with a gradient, plane 7 250 ~ 400mm lower than the upper plane of end carriage 2 on girder, on inclined-plane 4 on girder 8 and end carriage 3, the angle of plane is between 35 ° ~ 55 °, described telescopic shaft 3 moving up and down on end carriage 2 drives moving up and down of girder 8.
Principle of work: this crane main beam structure can adjust the relative height between girder 8 and end carriage 2, thus change the operation height of hoisting crane, the end carriage 2 of hoisting crane is provided with a gradient with the junction of girder 8 by the field of application expanding hoisting crane, make it smooth transition, ensure to make the overall height of common hoisting crane low when tonnage of driving a vehicle is identical, the corresponding reduction of factory building height, reduces costs; The gradient between end carriage 2 and girder 8 makes dolly smooth transition, ensure that structural strength.Structure is simple, and stable, cost-saving, applied widely, load-carrying capacity is strong.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
