Technical field
The utility model relates to the component parts that rails is directly spent somascope, more particularly, relates to a kind of directly spending at rails and is used for driving sensor in the somascope along measuring the driving mechanism that beam moves.
Background technology
Driving sensor is that rails is directly spent crucial parts in the somascope along the driving mechanism that the measurement beam moves.The rails of prior art is directly spent somascope sensor driving mechanism multiple form of structure, as worm and gear structure, ball nut screw structure, pulley cable mechanism etc.The pulley cable mechanism is with respect to worm and gear structure and ball nut screw structure, difficulty of processing is low, in light weight, certain advantage is arranged, no matter but be worm and gear structure and ball nut screw structure, or the pulley cable mechanism of prior art, all exist a such problem, be that driving mechanism moves in the process of implementing to detect along measuring beam at driving sensor, because the shift motion of sensor is longer, and needs to reset after detection is finished, moves back and forth to the big distance of sensor and tend to make sensor signal to draw winding displacement to twine mutually, influence moving steadily of sensor, certainty of measurement is reduced, twine when serious, even can make signal draw winding displacement to damage, the signal path fault occurs, somascope can't normally be worked.
The utility model content
Directly spend the deficiency that driving mechanism that the somascope sensor moves exists at the drive track rail of prior art, the purpose of this utility model aims to provide a kind of rails of new structure and directly spends somascope sensor driving mechanism, draw winding displacement with the existing sensor signal of rails straightness detector sensor driving mechanism that solves prior art and twine problem mutually, move stationarity and certainty of measurement to improve sensor.
The rails straightness detector sensor driving mechanism that the utility model is used to solve the problems of the technologies described above, main bag is arranged on active fixed pulley and the driven fixed pulley of measuring the beam two ends, running block, pull-cord and sensor signal are drawn winding displacement, pull-cord on the active fixed pulley, a termination in two traction termination lies in the sensor mount pad, a movable pulley of driven fixed pulley of another termination pile warp and running block lies in to be measured on the beam, another movable pulley that the signal of fixedlying connected with the sensor signal output port is drawn winding displacement pile warp running block is turned back to be fixed in and is measured on the beam, signal is drawn winding displacement and is become the parallel connection setting, constitutes the part that driving sensor moves pull-cord.
In technique scheme, described driven fixed pulley is the fixed pulley group that is no less than two fixed pulleys, one of them driven fixed pulley and the initiatively corresponding setting of fixed pulley, the corresponding setting with movable pulley of the driven fixed pulley of another one.
In technique scheme, the pulley axis of two movable pulley of described running block is interlaced, preferably is provided with in vertical mode.
In technique scheme, described sensor signal is drawn winding displacement and is fixed in the central part that the fixed point of measuring on the beam is positioned at the measurement beam.
In technique scheme, one end of driven fixed pulley of described hawser pile warp and movable pulley turn back lie in driven fixed pulley on the measurement beam at one end, preferably by tensioning spring lie in driven fixed pulley on the measurement beam at one end, so that make pull-cord keep tensioning state.
In technique scheme, described active fixed pulley design has the rope chute with the pull-cord coupling.
Of the present utility model open, directly spending somascope for rails provides a kind of driving sensor of brand new along measuring the driving mechanism that beam moves.The utility model is compared with the driving mechanism of prior art, wherein outstanding characteristics are, it is one of element that constitutes driving mechanism that sensor signal is drawn winding displacement, becomes the part that the traction laser instrument moves hawser, has signal of telecommunication transmission and the traction sensor moves dual-use function.This ingenious structure of the present utility model, guaranteed that the laser sensor signal draws winding displacement and can be in smooth-going state always, avoided signal to draw winding displacement fully and moved back and forth appearance winding in the process at sensor, and then avoided drawing a series of problems that winding displacement twines generation because of signal, improve rails and directly spent running stability, reliability and the certainty of measurement of somascope.
