Abstract
The utility model discloses a casting bridge crane lifting mechanism comprising rolling barrels (1) and two sets of reducers (2), brake devices (3), brake wheel couplers (4), compensating shafts (5), semi-tooth couplers (6) and motors (7), wherein the reducers (2), the brake devices (3), the brake wheel couplers (4), the compensating shafts (5), the semi-tooth couplers (6) and the motors (7) are connected in sequence. The number of the rolling barrels is two. Corresponding ends of the two rolling barrels (1) are connected through a full-tooth coupler (8). The other ends of the two rolling barrels (1) are respectively connected with the respective reducers (2). The casting bridge crane lifting mechanism has the advantages of being simple in structure and convenient to manufacture, solving the problem that rolling barrel bolts are cut off due to the fact that lifting is not synchronous, and avoiding potential safety risk and occurrence of safety accidents.
Description
Technical field
The utility model relates to a kind of casting crane in bridge type, particularly a kind of casting bridge crane hoisting mechanism.
Background technology
Mainly comprise an independently reel at existing most of casting bridge crane hoisting mechanism, the two ends of described reel are the retarder by connecting successively respectively, drg, the brake wheel coupler, compensating shaft be connected gear coupling and be connected with separately electrical motor, although such structure can be so that lifting mechanism takes up room less, but, because the reel two ends are connected with separately electrical motor by retarder and drg respectively, during motor start-up, can't accomplish synchronous startup, so that the synchronism of reel is relatively poor, in case reel can't carry out synchronously, the problem that can cause the reel bolt to occur being cut off occurs, and produces serious potential safety hazard.
The utility model content
The purpose of this utility model just provides and a kind ofly can guarantee the reel synchronous operated casting bridge crane hoisting mechanism that hoists.
The purpose of this utility model is to realize by such technical scheme, a kind of casting bridge crane hoisting mechanism, comprise reel, and two the cover retarder, drg, brake wheel coupler, compensating shaft, half gear coupling and the electrical motor that connect successively, described reel is two, described two corresponding ends of reel connect by Full-gear coupler, and the other end of described two reels is connected with separately retarder respectively.
Wherein, described reel comprises shell and turning cylinder, and described turning cylinder one end is connected with retarder, and the other end penetrates Full-gear coupler and is connected with Full-gear coupler.
Owing to adopted technique scheme, the utlity model has simple in structure, easily manufactured advantage, adopt it to solve because the potential safety hazard that the asynchronous reel bolt that causes that hoists is cut off has been avoided the generation of safety misadventure.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is reel of the present utility model and retarder and Full-gear coupler connection structure scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of casting bridge crane hoisting mechanism, comprise reel 1, and two the cover retarder 2, drg 3, brake wheel coupler 4, compensating shaft 5, half gear coupling 6 and the electrical motor 7 that connect successively, described reel 1 is two, described two reels, 1 corresponding end connects by Full-gear coupler 8, and the other end of described two reels 1 is connected with separately retarder 2 respectively.
Further describe, described reel 1 comprises shell 9 and turning cylinder 10, and described turning cylinder 10 1 ends are connected with retarder 2, and the other end penetrates Full-gear coupler 8 and is connected with Full-gear coupler 8.
In the utility model, electrical motor passes through half gear coupling, compensating shaft, brake wheel coupler, retarder to the reel transferring power, the driving dolly hoists, because the kinematic error of motor and retarder causes the rotation of reel asynchronous, just rely on Full-gear coupler to proofread and correct nonsynchronous problem between the two winding drum, make the synchronized operation of two winding drum energy, so just guaranteed the hoisting crane Operation safety.
Claims (2)
