Abstract
The utility model provides a connection structure between an encoder and a limiter on a crane, and the connection structure includes the encoder and the limiter. The input shaft of the encoder is connected together with the output shaft of the limiter through a drive shaft. By using of the mechanical transmission of the drive shaft, the connection structure between the encoder and the limiter on the crane enables a traditional retrofitting method of coaxial rotation of the encoder and the limiter to be changed in order to solve a problem that the normal operation of equipment is influenced due to the installation position of the encoder.
Description
Technical field
The utility model relates to the connection structure of a kind of coder and limiting device, particularly the connection structure of coder and limiting device on hoisting crane.
Background technology
Coder converts angular transposition or straight-line displacement to electric signal, and the former is called code-disc, and the latter is called yardstick.Can be divided into contact and contactless two kinds according to the playback mode coder.Contact adopts brush output, and a brush contact conduction region or insulation layer represent that the state of code is " 1 " or " 0 "; The contactless end instr of accepting is photosensor or magneto sensor, when adopting photosensor with photic zone and light tight district represent the state of code be " 1 " or " 0 ", the binary encoding by " 1 " and " 0 " is converted to electric signal that machine code can read in order to communication, transmission and storage with the physical signalling that gathers.
Now on the market, the method that installs coder additional is most for coupler, the limiting device output shaft is connected with the coder input shaft, makes its coaxial rotating.Although it is easy to install method additional, this method that installs additional can affect the running of lifting airborne equipment to a certain extent.
The utility model content
The purpose of this utility model is to provide the connection structure of coder and limiting device on a kind of hoisting crane, and this connection structure can freely change the installation site of coder as required, and does not affect being used in conjunction with of coder and limiting device.
The technical scheme that realizes the utility model purpose is: the utility model comprises coder and limiting device; The input shaft of described coder and the output shaft of limiting device link together by transmission shaft.
Above-mentioned transmission shaft is formed by connecting by at least two joint S. A.s, joint with save between be connected by universal-joint.
The utlity model has positive effect: (1) the utility model changed traditionally coder will with the method that installs additional of limiting device coaxial rotating; (2) the utility model can freely change the installation site of coder as required, and does not affect being used in conjunction with of coder and limiting device.(3) the utility model can avoid affecting because of the installation site of coder the problem of the normal operation of equipment.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, the utility model comprises coder 1 and limiting device 2; The input shaft 11 of described coder 1 and the output shaft 21 of limiting device 2 link together by transmission shaft 3.Described transmission shaft 3 is formed by connecting by at least two joint S. A.s, joint with save between be connected by universal-joint.Owing to having universal-joint on transmission shaft 3, therefore make transmission shaft can increase as required S. A. and direction-agile.Utilize this characteristic of transmission shaft 3, coder 1 can install additional as required, thereby has avoided affecting because of the installation site of coder 1 problem of the normal operation of equipment.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
