Abstract
The utility model discloses a mounting structure of a limiting device for a wire rope electric hoist, which comprises a crown gear, a driven gear, a fixed frame, a speed reducer and a rotation limiter which is connected with a shell of the speed reducer into a whole, wherein the speed reducer is connected with the rotation limiter in a transmission way, the shell is connected with a vertical plate of the fixed frame in a threaded way, the speed reducer is provided with an input shaft extending out of the shell, the axis of the input shaft is arranged vertically in a coplanar way relative to the axis of a winding drum shaft, the rotation limiter is arranged radially along the winding drum shaft, the crown gear is fixed on the shaft end of the winding drum shaft, the driven gear is fixed on the input shaft, and the crown gear is meshed with the driven gear. After the technology is adopted, the meshing precision of the crown gear and the driven gear is low, and the crown gear can be installed with low precision; the rotation limiter is arranged horizontally and is vertical to the input shaft in space, so that the overall height of the device is reduced, and the whole transmission chain structure from the meshed input of the crown gear to the output of the rotation limiter is compact.
Description
[ field of technology ]
The utility model relates to a mounting structure of a limiting device for a steel wire rope electric hoist, and belongs to the technical field of steel wire rope electric hoists.
[ background Art ]
In the limiting device for the common wire rope electric hoist, the rotary limiter is vertically installed, and is connected with the rotary shaft by using the coupler, so that the limiting device has the advantages of low installation precision, low failure rate and long service life, and the vertical rotary limiter with the coupler connected in the middle has the defect of large axial size, and the whole transmission structure of the whole limiting device is compact.
[ utility model ]
The utility model aims to provide a mounting structure of a limiting device for a steel wire rope electric hoist, which has a compact transmission chain structure and low precision requirement.
Therefore, the utility model adopts the following technical scheme:
the utility model provides a stop device's for wire rope electric block mounting structure, includes mount, reduction gear and links into an organic whole rotatory stopper with its casing of reduction gear to rotatory stopper is linked in the reduction gear transmission, and casing threaded connection is on the riser of mount, and the reduction gear has the input shaft that stretches out outside the casing, and its improvement point lies in: the rotary limiter is arranged along the spool shaft in a radial direction, the crown gear is fixed on the shaft end of the spool shaft, the driven gear is fixed on the input shaft, and the crown gear is meshed with the driven gear.
The base of the fixing frame is connected to the side wall plate through threads.
The utility model has the following advantages and beneficial effects:
the crown gear and the driven gear are meshed for transmission, so that the device can meet the requirement of counting the winding drums, the meshing precision of the crown gear and the driven gear is low, and the crown gear can be installed with low precision;
the adoption of the structure that the horizontal rotation limiter is vertical to the input shaft in space is beneficial to reducing the overall height of the limiting device, and the whole transmission chain structure of the crown gear meshed input to the output of the rotation limiter is compact, so that the device can be suitable for being installed in a narrower space.

[ detailed description ] of the utility model
Referring to fig. 1 to 7, a mounting structure of a limiting device for a wire rope electric hoist includes a fixing frame 1, a speed reducer and a rotation limiter 3 integrally connected with a housing 2 of the speed reducer, wherein the speed reducer is in transmission connection with the rotation limiter 3, the housing 2 is in threaded connection with a vertical plate 11 of the fixing frame 1 by two screws S2, the speed reducer has an input shaft 21 extending out of the housing 2, and the improvement is that: the rotary limiter 3 is arranged radially along the spool shaft, the crown gear 4 is fixed on the shaft end of the spool shaft, the driven gear 5 is fixed on the input shaft 21 through a connecting pin K, and the crown gear 4 is meshed with the driven gear 5.
The base 12 of the fixing frame 1 is connected to a side wall plate (a known part) of the steel wire rope electric hoist by adopting two screws S1 in a threaded manner.
The rotation of the spool shaft drives the crown gear to rotate, the speed reducer drives the rotation limiter, and finally counting of the number of rotations of the spool is realized, and when the spool rotates for 100 circles, the number of rotations is 1.
