Abstract
The utility model relates to a kind of crane travel mechanism, comprise end carriage, the wheel be located on end carriage, axletree, driver train, described driver train comprises electrical motor, the retarder of the top being located at end carriage, the axis of the output shaft of described retarder and the axis being parallel of axletree and extend in left-right direction, be in transmission connection by gear drive between the output shaft of described retarder and axletree.The top of end carriage is located at by the electrical motor of driver train, retarder by the utility model, hoisting crane is in operational process, the obstacle of driver train and end carriage side can be avoided to collide, do not need to leave certain anticollision space in the side of end carriage, and then the space in place can be made full use of, layout is more reasonable.
Description
Technical field
The utility model relates to crane field, is specifically related to crane travel mechanism.
Background technology
Traditional bridge, transfer crane, the drg of large and small car operating unit, retarder and electrical motor are that separately independently centre coupler and transmission shaft couple together, and transmission link is more, have impact on the stationarity of transmission efficiency and transmission.
Notification number is that the Chinese patent of CN202296861U discloses a kind of crane travel mechanism, comprise reducer structure, axletree, wheel, axletree is located between reducer structure and wheel, reducer structure is by drg, retarder and electrical motor integrator, this crane travel mechanism, decrease transmission link, but reducer structure is positioned at the side of wheel, time on the crossbeam this operating unit being applied to hoisting crane, reducer structure is positioned at the side of crossbeam, in hoisting crane operational process, the side being provided with reducer structure of crossbeam needs to leave certain space, prevent the phenomenon that reducer structure collides, the usage space in on-the-spot place certainly will be caused to be restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of reducer structure favorably situated crane travel mechanism, to solve the problem of existing restriction place usage space.
To achieve these goals, the utility model adopts following technical scheme: crane travel mechanism, comprise end carriage, the wheel be located on end carriage, axletree, driver train, described driver train comprises electrical motor, the retarder of the top being located at end carriage, the axis of the output shaft of described retarder and the axis being parallel of axletree and extend in left-right direction, be in transmission connection by gear drive between the output shaft of described retarder and axletree.
The driven gear that described gear drive comprises driving gear and engages with driving gear, described driving gear is arranged on the output shaft of retarder, and described driven gear is arranged on axletree.
Also be provided with intermediate gear between described driving gear and driven gear, described intermediate gear engages with driving gear and driven gear simultaneously.
The beneficial effects of the utility model are: the top of end carriage is located at by the electrical motor of driver train, retarder by the utility model, this crane travel mechanism is installed on after on hoisting crane, hoisting crane is in operational process, the obstacle of driver train and end carriage side can be avoided to collide, do not need to leave certain anticollision space in the side of end carriage, and then the space in place can be made full use of, layout is more reasonable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crane travel mechanism.
Detailed description of the invention
The embodiment of the utility model crane travel mechanism, as shown in Figure 1: comprise end carriage 10, the wheel 9 be located on end carriage 10, axletree 6 and driver train, wheel 9 rotates and is assemblied on axletree 6, and axletree 6 is arranged with bearing 8 between wheel 9 and axletree 6.Driver train comprises electrical motor 1, retarder 2, and driver train is positioned at the top of end carriage 10, electrical motor 1 through retarder 2 slow down after again through gear drive by transmission of power to axletree 6, drive wheel 9 walk.Gear drive comprises driving gear 3, driven gear 7 and the intermediate gear between driving gear 3 and driven gear 74, intermediate gear 4 engages with driving gear 3, driven gear 7 simultaneously, intermediate gear 4 is arranged on the gear wheel shaft 5 be located on end carriage 10, driving gear 3 is installed on the output shaft of retarder 2, driven gear 7 is installed on one end of axletree 6, and the axis of the output shaft of retarder 2, gear wheel shaft 5 and axletree 6 is parallel to each other.
In the present embodiment, intermediate gear is set between driving gear and driven gear, the scantling of structure of driving gear and driven gear can be reduced; In other embodiments, also can not intermediate gear be set, by driving gear and driven gear engaged transmission.
