In lower bearing periphery.
The encoder passes through a shaft coupling and gear axis connection as a further improvement of the utility model,.
The encoder is installed on towing plate side by a mounting base as a further improvement of the utility model,.
It is respectively formed with an annular flange in the gear both sides of the edge as a further improvement of the utility model, it should
The gear teeth of gear are formed between the annular flange of gear two sides.
The utility model has the following beneficial effects: by adding adaptive regulating mechanism, by between towing plate and axis of traction into
Row flexible connection, in the process of movement, can carry out certain automatic adjusument, the case where there are installation deviations for rack gear
Under, rack gear installation accuracy factor is contained, it is ensured that the accuracy of relative position, thus gear still can be stable
Rolling-operation, to enable the encoder to the data for accurately collecting spur roller gear feedback, i.e. encoder can be adopted accurately
Collect the accurate data signal of crane running position, driving positioning is accurately controlled convenient for encoder, makes crane
Obtain accurate lifting point.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific embodiment, to the utility model
It is described further.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy for reaching predetermined purpose and being taken, below in conjunction with
Specific embodiment of the present utility model is described in detail in attached drawing and preferred embodiment.
Fig. 1 is please referred to, the utility model embodiment provides a kind of adaptive location device for crane, including a tooth
Item 1, the coding for the gear 2 being engaged on rack gear 1, being set to the supercentral gear shaft 3 of gear 2, being connected to gear shaft 3
An adaptive regulating mechanism 5 between device 4 and tooth connection wheel shaft 3 and crane, wherein the adaptive regulating mechanism 5 includes
The towing plate 51 being connected on gear shaft 3 and flexible connection are in an axis of traction 52 of towing plate 51,52 rigidity of axis of traction
It is connected to crane.In specific application, axis of traction 52 is mounted on the branch of crane end carriage and/or hoist crab end carriage
On frame.
In the present embodiment, flexible connection is realized by a upper bearing (metal) 53 between the towing plate 51 and axis of traction 52.Tool
Body, which is sheathed on 52 periphery of axis of traction, and the towing plate 51 is sheathed on 53 periphery of upper bearing (metal).
The present embodiment realizes the flexible connection of towing plate 51 and axis of traction 52 by upper bearing (metal) 53, in the process of movement,
Certain automatic adjusument can be carried out, in rack gear 1 there are in the case where installation deviation, 1 installation accuracy factor of rack gear is carried out
