Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the left view of Fig. 1 device.
Among the figure: 1-body, 2-main shaft, 3-loam cake, 4-adjusting screw mandrel, 5-switch base, 6-optoelectronic switch, 7-back-moving spring, 8-clamp nut, 9-lower cover, 10-red LED lamp, 11-green LED lamp, 12-sender bar.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to describe in detail.
As depicted in figs. 1 and 2, the utility model a kind of from the stroke switchgear that resets comprises body 1, main shaft 2, back-moving spring 7, sender bar 12 and near switch.The body 1 of present embodiment is the rectangle cylindrical shell, and body 1 both ends of the surface are fixed with loam cake 3 and lower cover 9 respectively, and main shaft 2 promptly is located on the body 1 through loam cake 3 and 9 of lower covers.Loam cake 3 has through hole, and an end of main shaft 2 stretches out body 1 through this through hole, is used to prop up measured object.Lower cover 9 inboards are sleeve-like, and pegging graft with the other end of main shaft 2 cooperates; For avoiding relatively rotating between main shaft 2 and the lower cover 9, it is semicircular non-round symmetrical structure that main shaft 2 is processed into the cross section with the cooperation place of lower cover 9.Main shaft 2 is provided with flange, and back-moving spring 7 is arranged between flange and the lower cover 9, is used for resetting of main shaft 2.Sender bar 12 is arranged on the main shaft 2 in the body 1.In addition, body 1 both ends of the surface have also installed two adjusting screw mandrels 4, will regulate screw mandrel 4 through clamp nut 8 and compress.Each regulates all sheathed switch base 5 on the screw mandrel 4, and is fixing near switch on the switch base 5, present embodiment preferred light electric switch 6.Be provided with two indicator lights at body 1 outer surface, respectively as the load of two optoelectronic switches 6.
Main body with certain ship lift rises the reel brake shoe as measured object; Through rotating two adjusting screw mandrels 4, two optoelectronic switches 6 are respectively applied for detect the brake application signal that puts in place that puts in place and declutch, adopt red LED lamp 10 and green LED lamp 11 to indicate the brake application of brake shoe to put in place and declutch and put in place respectively; The operation principle of said apparatus is: when the ship lift main body rises the reel brake shoe and declutches; 2 pairs of back-moving springs 7 of main shaft that brake shoe promotes this device compress, and drive sender bar 12 simultaneously along axial-movement, when sender bar 12 during near an optoelectronic switch 6; These optoelectronic switch 6 actions are also sent the signal that declutches, and green LED lamp 11 lights; When the ship lift main body rose reel brake shoe brake application, back-moving spring 7 was pressed in main shaft 2 on the brake shoe, and followed the tracks of the brake shoe position all the time; Drive sender bar 12 simultaneously along axial-movement; When sender bar 12 during near another optoelectronic switch 6, these optoelectronic switch 6 actions are also sent the brake application signal, and red LED lamp 10 lights.
The core of the utility model be the nearly switch of two windings integrated so that whole apparatus structure exquisite, be easy to install; And adopt and regulate the position that screw mandrel 4 is regulated near switch; Realized the step-less adjustment of the position of the switch, guaranteed that the switch sender is realized in any position in travel range.So its protection range is not limited to the foregoing description.Obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model, and for example: body 1 can also be the tubular of circular or other shape; 2 modes of being located on the body 1 of main shaft are not limited to the form of loam cake among the embodiment 2 and lower cover 9, as long as can supports main shaft 2 and it can be moved vertically; It is that non-round symmetric shape such as square relatively rotates to avoid the two that the cross section also can be processed in main shaft 2 and the cooperation place of lower cover 9; Back-moving spring 7 also is not limited to be arranged between main shaft 2 flanges and the lower cover 9, and it also is feasible being arranged between loam cake and the main shaft 2 etc.; Also can adopt inductance approach switch etc. near switch, corresponding, sender bar 12 employing conductor materials etc. are to adapt.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and is out of shape interior.
