Abstract
The utility model relates to a crane trolley having large tonnage and low clearance. The crane trolley comprises a trolley frame, wherein the trolley frame comprises an upper trolley end beam and a lower trolley end beam; trolley maintenance platforms are arranged at the inner sides of the upper trolley end beam and the lower trolley end beam of the trolley frame; a main lifting transverse beam, a main lifting roller set and a support platform are arranged between the two trolley maintenance platforms in sequence from left to right; travelling motors are symmetrically arranged at one ends of the upper trolley end beam and the lower trolley end beam; a lifting decelerator is arranged at the outer side of the lower trolley end beam; a lifting motor and a brake are arranged at the inner coaxial side of the support platform; a groove is arranged on the lower trolley end beam; the disc brake is in the groove; or, the disc brake is arranged on the trolley end beam; and the disc brake is embedded in the trolley end beam. The crane trolley having large tonnage and low clearance disclosed by the utility model is capable of reducing structural materials, and therefore, the trolley structure is more reasonable and compact.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of large-tonnage low clearance monkey.
Background technology
European hoisting crane generally is only limited to the hoisting crane of the following working level of A5, major cause is because the monkey of the above working level of A6, need to arrange dual brake, and the monkey of the following working level of A5 only need to be arranged a drg, be to make lifting motor below the 50t for little position, drg, the structure that retarder is three-in-one, this structure is only suitable for the hoisting crane of the following working level of A5, and its lifting motor power is confined to 45KW, above or the high hoisting crane of lifting velocity of 50t, can only use the lifting mechanism transmission that separates, it is motor, drg (containing coupler), retarder, the reel group, assembly pulley, steel rope, the suspension hook group, and the dolly of the large-tonnage low clearance hoisting crane of the above working level of A6 is two drgs of bad layout.
Summary of the invention
European hoisting crane generally is only limited to the hoisting crane of the following working level of A5, major cause is because the monkey of the above working level of A6, need to arrange dual brake, and the monkey of the following working level of A5 only need to be arranged a drg, be to make lifting motor below the 50t for little position, drg, the structure that retarder is three-in-one, this structure is only suitable for the hoisting crane of the following working level of A5, and its lifting motor power is confined to 45KW, above or the high hoisting crane of lifting velocity of 50t, can only use the lifting mechanism transmission that separates, it is motor, drg (containing coupler), retarder, the reel group, assembly pulley, steel rope, the suspension hook group, and the dolly of the above working level large-tonnage of A6 low clearance hoisting crane is two drgs of bad layout.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, a kind of have novel structure, compactness to be provided, cost-effective a kind of large-tonnage low clearance monkey.
The purpose of this utility model is achieved through the following technical solutions: a kind of large-tonnage low clearance monkey, comprise trolley frame, trolley frame comprises the dolly end carriage, lower dolly end carriage, be provided with the dolly maintenance platform at the upper dolly end carriage of trolley frame and the inboard of lower dolly end carriage, between two dolly maintenance platforms, be provided with successively from left to right the main crossbeam that hoists, main hoisting drum group and support platform, end at upper dolly end carriage and lower dolly end carriage is arranged with movable motor, the outside at lower dolly end carriage is provided with speed reducer used in hoisting, coaxial inboard in support platform is provided with lifting motor and drg, one end of drg is connected with plate disc brake by floating axle, be provided with groove at lower dolly end carriage, plate disc brake is positioned at described groove, perhaps be provided with plate disc brake at the dolly end carriage, plate disc brake is embedded in the dolly end carriage.
The utility model compared with prior art has the following advantages: by optimal design, reduce structure material, make vehicle structure more reasonable, compact.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of a kind of embodiment of the present utility model;
Fig. 3 is the structural representation of another kind of embodiment of the present utility model;
Number in the figure: 1-dolly maintenance platform, 2-master hoist crossbeam, 3-master's hoisting drum group, 4-support platform, 5-movable motor, 6-speed reducer used in hoisting, 7-lifting motor, 8-drg, 9-floating axle, 10-plate disc brake, 11-groove.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Show a kind of large-tonnage low clearance of the utility model monkey such as Fig. 1, comprise trolley frame, trolley frame comprises the dolly end carriage, lower dolly end carriage, be provided with dolly maintenance platform 1 at the upper dolly end carriage of trolley frame and the inboard of lower dolly end carriage, between two dolly maintenance platforms 1, be provided with successively from left to right the main crossbeam 2 that hoists, main hoisting drum group 3 and support platform 4, an end of dolly end carriage and lower dolly end carriage is arranged with movable motor 5 on described, be provided with speed reducer used in hoisting 6 in the outside of lower dolly end carriage, be provided with lifting motor 7 and drg 8 in the coaxial inboard of support platform 4, one end of drg 8 is connected with plate disc brake 10 by floating axle 9, be provided with groove 11 at lower dolly end carriage, plate disc brake 10 is positioned at groove 10, perhaps be provided with plate disc brake 9 at the dolly end carriage, plate disc brake 9 is embedded in the dolly end carriage.
The utility model by optimal design, reduces structure material, vehicle structure is more reasonable, compact, because plate disc brake 9 places in the groove 10 or is embedded in the dolly end carriage, the dolly whole height is reduced, factory building height has also reduced simultaneously, has greatly reduced the advantages such as productive costs.
