The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As depicted in figs. 1 and 2; A kind of embodiment according to the utility model provides a kind of angle indicating instrument; This angle indicating instrument comprises supporting plate 1, angle direction board 2 and pointer 3, and said angle direction board 2 is arranged on the said supporting plate 1 and indicates scale, and said pointer 3 is installed on the said supporting plate 1 free to rotately and points to the scale on the said angle direction board 2; Wherein, the plate face angulation of the surface that indicates scale of said angle direction board 2 and said supporting plate 1.
Pass through technique scheme; Because the surface that indicates scale of angle direction board 2 and the plate face angulation of supporting plate 1; Therefore the staff need not the plate face towards supporting plate 1; Only need the surface that indicates scale, just can observe the indicated angle of pointer 3, thereby be convenient to use towards angle direction board 2.When for example utilizing this angle indicating instrument to detect the change angle of arm of hoisting crane, can this angle indicating instrument be installed on the side of arm of hoisting crane, make the plate face of supporting plate 1 and the parallel sided of arm.Because the surface that indicates scale of angle direction board 2 and the plate face angulation of supporting plate 1; Therefore the surface that indicates scale of this angle direction board 2 can be towards the operator's compartment or the operator's compartment of hoisting crane; Thereby the staff can observe the pointer 3 of this angle indicating instrument scale pointed in the operator's compartment of hoisting crane or the operator's compartment easily; Be convenient to the information that the staff grasps the arm change angle in real time, make operation safe reliable.
The plate face angulation of the surface that indicates scale of angle direction board 2 and supporting plate 1 can be provided with according to concrete applicable cases.When for example being installed on the crane arm; If the observation window of the operator's compartment of hoisting crane or operator's compartment is towards the end face of arm; And this end face is common and the lateral vertical of arm; Then this moment, angle direction board 2 the surface that indicates scale can be vertical each other with the plate face of said supporting plate 1, thereby the staff can observe the pointer 3 of this angle indicating instrument scale pointed in the operator's compartment of hoisting crane or the operator's compartment easily.
Supporting plate 1 can adopt various suitable shapes, and for example extremely shown in Figure 8 like Fig. 1, said supporting plate 1 is roughly fan-shaped, and the surperficial general curved that indicates scale of said angle direction board 2 becomes circular-arc, and is arranged on the circular arc side face of said supporting plate 1.
Movable connection the for can freely rotating each other between supporting plate 2 and the pointer 3.Above-mentioned angle indicating instrument is installed to movable parts (the for example arm of hoisting crane) is gone up so that when detecting the angle that is moved of this movable parts; Can any one in supporting plate 2 and the pointer 3 be fixed on this movable parts with along with this movable parts moves together; And make another person's by gravity keep vertical position; Just can indicate the scale on the angle direction board 2 that is arranged on the supporting plate 2 through pointer 3, with the respective angles that shows that movable parts was moved.Can guarantee that these parts keep vertical position through counterweight portion is set on parts.For example if supporting plate 2 is fixed on the movable parts and when making pointer 3 keep vertical positions, said pointer 3 also comprises and said hold-down arm 31 bonded assembly counterweight portions.Counterweight portion can adopt various suitable forms to realize; For example in embodiment as shown in the figure; Said counterweight portion comprises weight arm 33 and balance weight body 34, and said weight arm 33 is captiveed joint with said hold-down arm 31 angledly, and said balance weight body 34 is arranged on the end of said weight arm 33.Certainly, also can on supporting plate 2, counterweight portion be installed, and pointer 3 is fixed on the movable parts with along with this movable parts moves together so that supporting plate 2 by gravitys keep vertically.
Preferably, also indicate the subscale mark (not shown) on the plate face of said supporting plate 1, the hold-down arm 31 of said pointer 3 points to said subscale mark.Thereby the staff also can observe the indicated scale of pointer 3 on the plate face of supporting plate 1 time, further is convenient to the use of angle indicating instrument.
Like Fig. 1 Fig. 2, Fig. 6 and shown in Figure 7, the angle indicating instrument also comprises the mount pad 5 that is fixed on the said supporting plate 1.Thereby the angle indicating instrument is fixed on the movable parts to be measured through this mount pad 5.Supporting plate 1 can form as one with mount pad 5.
Can realize movable connection that can freely rotate each other between supporting plate 2 and the pointer 3 through various suitable modes, for example install through rotating shaft and bearing.As a kind of easy mode, as shown in Figure 2, said pointer 3 is installed on the said supporting plate 1 through bolt 6 free to rotately.
Above-mentioned angle indicating instrument can be applied to the occasion of various needs, and is for example as indicated above, can be installed to the side of the arm of hoisting crane, to detect the change angle of this arm.Therefore on the other hand according to the utility model; A kind of hoisting crane also is provided; This hoisting crane comprises arm, operator's compartment and operator's compartment; Wherein, said hoisting crane also comprises the angle indicating instrument as indicated above that is arranged on this arm, and the surface that indicates scale of said angle direction board 2 and affiliated operator's compartment or operator's compartment are relative.Thereby be convenient to the information that the staff grasps the arm change angle in real time, make operation safe reliable.
This angle indicating instrument can be installed on any appropriate location of arm through various suitable modes, and for example the said supporting plate 1 of this angle indicating instrument (perhaps mount pad 5) is fixed on the side of arm.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
