The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Referring to figs. 1 through shown in Figure 4; Present embodiment hoisting crane cylinder steel rope anticreep groove dislocation device; Be arranged on the wire rope drum 1 that is wound with steel rope under; Steel rope changed course support 7 is detected at least one middle part that comprise base plate 2, detect steel rope 3, spacing detected activity bar 4, steel rope changed course support 5 detects in the head end portion under the both ends of wire rope drum 1 of being arranged on, terminal part detects steel rope changed course support 6, testing circuit, is arranged under the middle part of wire rope drum 1; Each detects steel rope changed course support 5,6,7 and vertically is fixed on the base plate 2; Its top is equipped with changed course roller 8; The head end that detects steel rope 3 is fixed on the base plate 2, twines changed course roller 8 backs that the changed course roller 8, the terminal part that changed course roller 8, middle part that head end portion detects steel rope changed course support 5 detect steel rope changed course support 7 detect steel rope changed course support 6 successively and connects spacing detected activity bar 4, and terminal part detects steel rope changed course support 6 and is provided with limit switch 9.
The principle of work of present embodiment hoisting crane cylinder steel rope anticreep groove dislocation device is: when slack rope appears in the steel rope on the wire rope drum 1; The steel rope by gravity can drop and run into and oppress and detect steel rope 3; Make and detect spacing detected activity bar 4 risings of steel rope 3 drives; Spacing detected activity bar 4 collision terminal parts detect the limit switch 9 on the steel rope changed course support 6, and limit switch 9 sends signal and sends signal to testing circuit, and testing circuit control hoisting crane is shut down.
Swing when preventing that spacing detected activity bar 4 from rising, guarantee to operate steadily, terminal part detects on the steel rope changed course support 6 end and is installed on the position-limited rack 10; Position-limited rack 10 bottoms are installed on the base plate 2; Position-limited rack 10 has cross connecting plate 11, and cross connecting plate 11 is provided with pilot hole 12, and spacing detected activity bar 4 passes pilot hole 12; Thereby can only move at vertical direction; Effectively limited the degree of freedom of spacing detected activity bar 4 on other direction, prevented its swing, guaranteed to operate steadily.
For guaranteeing the particularity of spacing action, sheathed being equipped with hit roller 13 on the spacing detected activity bar 4, hits roller 13 and is spindle, and volume is bigger, is convenient to contact limit switch, hits roller 13 and is installed on the spacing detected activity bar 4 through screw tightening.Simultaneously; Hitting the spacing operating space of roller 13 on spacing detected activity bar 4 can adjust; Through unscrewing screw, change and hit roller 13 and withstand on the spacing detected activity bar 4 at the screw of screwing again behind the position on the spacing detected activity bar 4 and get final product, guaranteed the particularity of spacing action.
Pull out pilot hole 12 for preventing spacing detected activity bar 4; Top end on spacing detected activity bar 4 and bottom end position are equipped with anticreep groove nut 14; Top end on the spacing detected activity bar 4 and bottom end position respectively are provided with one section screw thread, so, and also can be as required; Regulate the position of anticreep groove nut 14, thereby regulate actuation range.
Based on technique scheme; Alternatively; Each detects steel rope changed course support 5,6,7 can carry out height adjustment to adapt to different wire rope drum 1 installation forms, and each detects steel rope changed course support 5,6,7 and comprises outer tube and the interior pipe that is threaded, changed course roller 8 corresponding installations on inner pipe.As shown in Figure 5; Detecting steel rope changed course support 7 with the middle part is example; Interior pipe 7-1 has outside thread, and outer tube 7-2 has negative thread, and interior pipe 7-1 and outer tube 7-2 screw thread are installed together; And fastening through nut, change the height that steel rope changed course support 7 is detected at the middle part through the precession length of managing 7-1 in regulating.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or the equivalent embodiment of the equivalent variations of retrofiting.But everyly do not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of technical scheme of the present invention according to technical spirit of the present invention.
