Abstract

The utility model relates to a large-tonnage dual-beam crane trolley, which comprises girders , end beams, a reel, a reduction gear, a motor and a dolly driving mechanism. The model is characterized in that the end beams are two parallel beams, between two end beams are connected with two parallel girders. One of the girders is equipped with the reel and the reduction gear and the other girder is equipped with an assembly pulley. The input shaft and output shaft of the reduction gear are respectively arranged on the two corresponding sides. The output shaft of the reduction gear is connected with the reel. The input shaft of the reduction gear is connected with the motor and the motor is arranged on the end beam. The dolly driving mechanism is arranged on the end beam. The utility model has advantages of simple and small structure, light dead weight and is easy to process and assemble.

Description

A kind of large-tonnage twin beams crane carriage
Technical field
The utility model belongs to the weight-lifting equipment technical field, particularly relates to a kind of large-tonnage twin beams crane carriage.
Background technology
At present, volume is little because of having, use and characteristics such as easy for installation are widely used in fields such as nuclear power, metallurgy, machinery, chemical industry, oil and the energy for electric hoist crane.Existing cucurbit formula twin beams crane carriage, all below 50t, in order to strengthen the lifting weight of crane carriage, the car fare of crane carriage adopts the plate splicing to hoisting capacity more, the vehicle frame that is crane carriage is formed by shaped steel and board material splice, and technology making and fitting process are very loaded down with trivial details.In addition, as shown in Figure 2, motor 5 in the existing cucurbit formula twin beams crane carriage is arranged in parallel with reel 3, be that the input shaft of the retarder 4 on the monkey and output shaft are in the same side, motor 5 is connected with the input shaft of coupler with retarder 4 by drg 9, and reel 3 is connected with the output shaft of retarder 4.The crane carriage of said structure for rope device and the motor that guarantees reel do not interfere, must be provided with certain distance between the axis of reel and the axis of electric machine main shaft, so will increase the crane carriage volume.
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, volume is little, be easy to large-tonnage twin beams crane carriage from heavy and light, process and assemble.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of large-tonnage twin beams crane carriage, comprise girder, end carriage, reel, retarder, motor and drive car, it is characterized in that: described end carriage is two parallel girders, between two parallel end carriages, be connected with two parallel girders, wherein on a girder reel and retarder are installed, on another girder assembly pulley is installed, described input shaft of speed reducer and output shaft are respectively on the two opposite side surfaces of retarder, the output shaft of retarder is connected with reel, input shaft of speed reducer is connected with motor, motor is installed on the end carriage, and described drive car is installed on the end carriage.
The utility model can also adopt following technical scheme:
Described motor is a braking motor.
Also be connected with the girder that electric cabinet is installed between described two end carriages.
Advantage and the good effect that the utlity model has are: because as above technical scheme of this novel employing, the framework that is crane carriage is by girder and end carriage bonded assembly framed structure, girder is connected between two end carriages that are parallel to each other, reel and retarder are installed on the same girder, reel is connected with the output shaft of retarder, input shaft of speed reducer is on the opposite flank of output shaft, input shaft of speed reducer is connected with motor, motor is installed on the end carriage, the crane carriage of said structure adopts girder to be connected with end carriage, can lift by crane the large-tonnage weight.Reel, retarder and motor series arrangement are on the framework of crane carriage, compare the distributed architecture in parallel of existing reel and motor, needn't consider the distance between spool axis and the electric machine main shaft axis, this reel, retarder and motor in novel not only compact conformation, distribution space is little, and easy accessibility.
On the main shaft during this is novel assembly pulley is installed, use is closed in the lifting hook pulley assembly of assembly pulley, reel and crane carriage, can make the reel rope stretching change single rope stretching into by traditional double-rope, under the certain condition of sling height, can shorten the reel length of half, thereby dwindle the volume of crane carriage.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 prior art constructions scheme drawing;
Fig. 3 is the solderless wrapped connection sketch of this novel middle steel rope.
Among the figure: 1, girder; 2, end carriage; 3, reel; 4, retarder; 5, motor; 6, assembly pulley; 7, electric cabinet; 8, drive car; 9, drg; 10, steel rope; 11, hook block group.
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 and Fig. 3, a kind of large-tonnage twin beams crane carriage, comprise two end carriages that are parallel to each other 2, article two, connect girder 1 between the end carriage 2, girder 1 adopts the plate and the bolt of buckle head to be connected with end carriage 2, girder 1 is three beams that are parallel to each other, wherein on a girder 1 reel 3 and retarder 4 are installed, reel 3 is connected with the output shaft of retarder 4, connect motor 5 on the input shaft of retarder 4, input shaft of speed reducer and output shaft are respectively on the two opposite side surfaces of retarder, realize reel, the series arrangement of retarder and motor, motor 5 is braking motor (product that can buy on the market), this braking motor can prevent the reel reversing when breaking down, avoid potential safety hazard, motor 5 is installed on the end carriage 2; On the girder 1 adjacent with reel 3 assembly pulley 6 is installed, with the hook block group 11 of reel 3 bonded assembly single wire ropes, 10 solderless wrapped connection assembly pulleys 6 and crane carriage, that so realizes reel singly goes out rope structure; Article three, electric cabinet 7 is installed on the girder 1.Drive car 8 is installed on above-mentioned two end carriages 2, drive car 8 comprise drive motor and with drive motor bonded assembly running roller.
