Abstract
The utility model discloses an angle scale comprising an indicating arrow, a scale plate and an indicating arrow fixing shaft, wherein the indicating arrow fixing shaft is welded at the circle center position of the scale plate; and one end of the indicating arrow is provided with a circular hole and connected with the indicating arrow fixing shaft through a nut. With the angle scale, an operator can clearly observe the working angle of a moving part and conveniently know actual working conditions.
Description
Technical field
The utility model relates to a kind of angle scale.
Background technology
In the 30T-25M crane for ship, arm need be done 0 ° to 85 ° luffing motion, arrives 85 ° of positions and leans on the limit switch control action to stop.If but limit switch is out of control, because operator's compartment is near jib, driver's seat is open inadequately, can not the better controlled change angle, and safety misadventure takes place in arm and be thrown to the loop wheel machine rear side easily under this situation.
The utility model content
The utility model technical matters to be solved provides a kind of operating angle that can clearly observe movement parts, is convenient to the angle scale that operating personal is grasped actual condition.
The utility model adopts following technical scheme in order to solve the problems of the technologies described above: the utility model has designed a kind of angle scale; Comprise arrow, scaleplate and arrow anchor shaft; Said arrow anchor shaft is welded on the home position of scaleplate; One end of said arrow has circular hole, and said circular hole is connected with the arrow anchor shaft through nut, wherein:
Also comprise the rotation jib, said scaleplate is fastenedly connected in one with the rotation jib, and calibrated disc 0 degree position scale line becomes plumbness with horizon.
Optimize structure as a kind of of the utility model: the Circularhole diameter of said arrow one end is than the big 2mm of diameter of said arrow anchor shaft.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
1. the angle scale shown in the utility model is simple in structure, safe reliability is higher;
2. the angle scale shown in the utility model can help chaufeur and grasp actual condition so that operating personal is clearly observed loop wheel machine jib operating angle at operator's compartment, has improved the safety of work.
Description of drawings
Fig. 1 is the structural representation of the utility model institute design-calculated angle scale;
Fig. 2 is the lateral plan of the utility model institute design-calculated angle scale;
Fig. 3 is the installation site scheme drawing of the utility model institute design-calculated angle scale on the work jib;
Fig. 4 is the work scheme drawing of the utility model institute design-calculated angle scale on the work jib.
The 1-scaleplate, the 2-arrow, 3-arrow anchor shaft, 4-rotates jib.
The specific embodiment
Below in conjunction with accompanying drawing the technical scheme of the utility model is done further detailed description:
As depicted in figs. 1 and 2; The utility model has designed a kind of angle scale; Comprise arrow, scaleplate and arrow anchor shaft; Said arrow anchor shaft is welded on the home position of scaleplate, and an end of said arrow has a circular hole, and said circular hole is connected with the arrow anchor shaft through nut.
As shown in Figure 3; In order to let operating personal when controlling, observe the turned position of angle scale simultaneously, the utility model has also designed a rotation jib, said scaleplate with the rotation jib be fastenedly connected in one; Should be when the rotation jib be horizontal during installation; During use, calibrated disc 0 degree position scale line just in time becomes plumbness with horizon, and just arrow is aimed at " 0 ° " position of scaleplate.
Can under the deadweight influence, do free gyroscopic movement in order to make arrow; The Circularhole diameter of one end of arrow described in the utility model is than the big 2mm of diameter of said arrow anchor shaft; To guarantee that enough gaps make arrow under the deadweight influence, do free gyroscopic movement; Like this; Operating personal can clearly observe the operating angle of movement parts, is convenient to operating personal and grasps actual condition, is illustrated in figure 4 as the rotation jib and rotates to the working condition when becoming 30 ° with horizon.
Claims (2)
1. angle scale; Comprise arrow, scaleplate and arrow anchor shaft, said arrow anchor shaft is welded on the home position of scaleplate, and an end of said arrow has circular hole; Said circular hole is connected with the arrow anchor shaft through nut; It is characterized in that: also comprise the rotation jib, said scaleplate is fastenedly connected in one with the rotation jib, and calibrated disc 0 degree position scale line becomes plumbness with horizon.
2. angle scale according to claim 1 is characterized in that: the Circularhole diameter of said arrow one end is than the big 2mm of diameter of said arrow anchor shaft.
