Abstract
The utility model relates to a rack-and-pinion dolly positioning coding device which includes a rack arranged on the inner side of a dolly track and a pinion support welded on a positioned dolly pedestal. The pinion support is provided with a pinion which engages with the rack. The pinion is provided with a coder. The rack-and-pinion dolly positioning coding device can realize the high-precision positioning of the dolly, and the higher the resolution rate of the coder, the higher the dolly positioning precision.
Description
Technical field:
The utility model relates to a kind of dolly location coding device of rack-and-pinion, is fit to the higher cranes of positioning requirements such as steel pipe rolling conveyor, nuclear fuel conveyor.
Background technology:
Monkey location in the past is mostly by adopting at car wheel installation scrambler or by the freely dragging wheel scrambler being installed and being come dolly is positioned, but there are some drawbacks, the wheel of scrambler and other wheels for example are installed not at grade, cause occurring wheel hanging, the scrambler reading is inaccurate, affects bearing accuracy; Wheel hanging when track is out-of-level to cause carriage walking to a certain position is arranged again; Car wheel gnaw rail and freely dragging wheel with track fully contact all can cause the numerical value of scrambler record deviation to occur so that dolly location distortion.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, a kind of hi-Fix that can realize dolly to be provided, the dolly location coding device of a kind of rack-and-pinion that encoder resolution is higher, the degree of accuracy of dolly location is higher.
The purpose of this utility model is achieved through the following technical solutions: a kind of dolly location coding device of rack-and-pinion, comprise the tooth bar that is installed in the trolley track inboard and the gear stand that is welded on the positioning trolley base, install and the tooth bar meshed gears at gear stand, scrambler is installed on the gear.
The utility model compared with prior art has the following advantages: the utility model can make the positioning trolley range data forever keep by rack-and-pinion location coding device, does not need zero clearing to set and eliminates cumulative errors, and the system cut-off data can not lost.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Number in the figure: 1-gear, 2-gear stand, 3-scrambler, 4-tooth bar.
Embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Fig. 1 shows the dolly location coding device of a kind of rack-and-pinion of the utility model, comprise the tooth bar 4 that is installed in the trolley track inboard and the gear stand 2 that is welded on the positioning trolley base, install and tooth bar 4 meshed gears 1 at gear stand 2, scrambler 3 is installed on the gear 1.
At first the tooth bar disjunction is made, needed to guarantee the continuous of tooth, make through finishing through after the final operation thermal treatment.Gear is made by whole finishing, and tooth bar is installed first, then gear stand is welded on the positioning trolley base, and then gear and scrambler are installed successively, for avoiding the car wheel transverse shifting, at the dolly two ends angle sheave is installed.Gear is to move with dolly, and tooth bar is fixed on the girder of track inboard, so that positioning trolley meshes fully at process middle gear and the tooth bar of operation, does not have relative sliding, reading by scrambler is determined the displacement of the relative girder of travelling car in real time, realizes that dolly accurately locates.
The utility model can make the positioning trolley range data forever keep by rack-and-pinion location coding device, does not need zero clearing to set and eliminates cumulative errors, and the system cut-off data can not lost.
