Abstract
The utility model relates to a distance measurer of an electric hoist. The distance measurer of the electric hoist comprises a fixed frame, wherein a pulley block is arranged on the fixed frame and at least comprises a movable pulley and two fixed pulleys; the two fixed pulleys are positioned on two sides of the movable pulley respectively; an encoder is connected to a pulley shaft of the movable pulley; a rope is configured on the pulley block; a counterweight is fixedly arranged at one end of the rope, and the other end of the rope is connected to a hoisting mechanism of the electric hoist. The hoisting accuracy of the electric hoist is measured by the coordination of the pulley block and the encoder; the distance measurer of the electric hoist is simple in structure, and can also be used for measuring the distance when various specially-shaped pieces are hoisted by the electric hoist; the accuracy is as high as 0.1mm.
Description
Technical field
The utility model relates to electric block measurement detecting device in use, specifically a kind of electric block macrometer.
Background technology
Electric block in use needs to detect its precision that hoists sometimes.In prior art, conventionally adopt manually range finding from method detect, this method precision is low, can only detect roughly, cannot reach the precise evaluation to its performance.
Also some company is by being used the similar techniques such as opto-electronic pickup to detect the electric block precision that hoists, although higher than manual inspection precision, the highest grade that can only reach of precision, needs more high-precision occasion just cannot use for those.The profiled piece lifting of mensuration effect when in addition, this technology is carried out to(for) electric block is very undesirable.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of electric block macrometer that can reach 0.1mm precision.
According to the technical solution of the utility model: a kind of electric block macrometer, comprise fixed mount, on described fixed mount, assembly pulley is installed, described assembly pulley at least comprises a movable pulley and two fixed pulleys, described two fixed pulleys lay respectively at the both sides of described movable pulley, on the wheel shaft of described movable pulley, be connected with coder, on described assembly pulley, dispose rope; One end of described rope is fixed with counterweight counterweight, and its other end is connected on the lifting mechanism of electric block.
Described fixed pulley is fixed on described fixed mount by fixed pulley support.
Described movable pulley is fixed on described fixed mount by moving pulley bracket.
Described rope adopts steel rope.
Technique effect of the present utility model is: the utility model is the precision that hoists that coordinates to measure electric block with coder by assembly pulley, and simple in structure, precision is high, can reach 0.1mm precision; The utility model also can be used for electric block measuring distance when the various profiled piece of lifting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, Fig. 2, comprise rope 1, fixed mount 2, assembly pulley 3, fixed pulley 4, fixed pulley support 5, movable pulley 6, moving pulley bracket 7, counterweight counterweight 8, coder 9 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of electric block macrometer, comprises fixed mount 2, and assembly pulley 3 is installed on fixed mount 2.
Assembly pulley 3 at least comprises a movable pulley 6 and two fixed pulleys 4.Fixed pulley 4 is fixed on fixed mount 2 by fixed pulley support 5, and movable pulley 6 is fixed on fixed mount 2 by moving pulley bracket 7.Two fixed pulleys 4 lay respectively at the both sides of movable pulley 6.On assembly pulley 3, dispose rope 1; Rope 1 preferably adopts steel rope.One end of rope 1 is fixed with counterweight counterweight 8, and its other end is connected on the lifting mechanism of electric block.
On the wheel shaft of movable pulley 6, be connected with coder 9.
Principle of work of the present utility model is as follows: 3 work of Electromotion Hoist Mechanism up-and-down movement band running block, and by rotation drive coder 5 work of movable pulley 6.By the displacement of measuring Electromotion Hoist Mechanism in the program of 5 li of coders, and precision can arrive 0.1mm.
The utility model is not only applicable to the range finding of electric block, and can measure well the distance of various profiled piece activities, can, by changing the quantity of mounting means and the increase assembly pulley 3 of fixed mount 2, complete the range observation of other occasions yet.
By the utility model, can have more efficiently assessment to the performance of the electric block of producing, and with low cost, overhaul more conveniently, effectively guaranteed the quality of electric block, can produce quickly customer satisfaction system electric block.
