Abstract
The utility model relates to a connecting structure between a trolley and an end beam of a large crane, which comprises a trolley and an end beam. The connecting structure is characterized in that an equalizing beam is arranged between the trolley and the end beam; a support saddle is fixedly installed at the lower end of the end beam; the support saddle is connected with the upper end of the equalizing beam through a connecting shaft; support saddles are fixedly installed in symmetry at the lower end of the equalizing beam; and the support saddles are connected with the trolley through connecting shafts. Therefore, the structure is high in equalizing precision, even in stress strain and high in work efficiency. In addition, the connecting structure is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of goliath chassis and end carriage connection structure.
Background technology
At present, existing crane facility end carriage and chassis adopt direct connection usually, and promptly end carriage is directly sat and is contained on the chassis stand.Along with the lifting of lifting load-carrying capacity, the number of chassis also increases thereupon, adopts above-mentioned mounting means can not satisfy array wheel straightness accuracy on the chassis, causes between the chassis deviation bigger, like this when operation because not enough generation of straightness accuracy gnawed the rail phenomenon; The above-mentioned in addition mounting means operating time is long, can not once mounting locate, so inefficiency, labour intensity is big.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, balance quality is high and stressed uniform goliath chassis and end carriage connection structure.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of goliath chassis and end carriage connection structure, comprise: chassis, end carriage, it is characterized in that: be provided with equalizing bar between described chassis and the end carriage, described end carriage lower end is fixed with bearing, bearing is connected with the upper end of equalizing bar by adapter shaft, the lower end symmetry of equalizing bar is fixed with bearing, and bearing is connected with chassis by adapter shaft.
The utility model can also adopt following technical measures:
The both sides that described end carriage lower end installs bearing are provided with locating piece.
The both sides that described equalizing bar lower end installs bearing are provided with locating piece.
Advantage and the good effect that the utlity model has are: owing to is connected by equalizing bar between chassis and the end carriage, described end carriage lower end is provided with and is arranged with locating piece, is fixed with bearing between locating, and bearing is connected with the upper end of equalizing bar by adapter shaft; The lower end of equalizing bar is provided with locating piece, is fixed with bearing between locating piece, and bearing is connected with chassis by adapter shaft.Therefore said structure balance quality height, stressed evenly and high efficiency, the utility model also has advantages such as simple in structure, easy for installation in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, chassis; 2, end carriage; 3, equalizing bar; 4, locating piece; 5, bearing; 6, adapter shaft; 7, bearing; 8, adapter shaft; 9, locating piece.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, be connected by equalizing bar 3 between chassis 1 and the end carriage 2, described end carriage 1 lower end is fixed with bearing 5 by bolt, and bearing 5 is connected with the upper end of equalizing bar 3 by adapter shaft 6, and the bilateral symmetry that installs bearing 5 places in end carriage 2 lower ends is provided with locating piece 4; The lower end symmetry of equalizing bar 3 is fixed with bearing 7, and bearing 7 is connected with chassis by adapter shaft 8, and the bilateral symmetry that equalizing bar 3 lower ends install bearing 5 places is provided with locating piece 9.Therefore said structure balance quality height, stressed evenly and high efficiency, the utility model also has advantages such as simple in structure, easy for installation in addition.
