The first switch slider 104 and second switch slider 110 are housed respectively on the connection box for motor 113, connection box for motor 113 built-in first micro-switch 105 and second micro-switchs 111, the described first switch slider 104 connects described first micro-switch 105, and second switch slider 110 connects described second micro-switch 111.
The utility model embodiment also provides a kind of electric block, and as depicted in figs. 1 and 2, it comprises:
Described spacing framework 101 connects with rotation coupling block 107 usefulness first hinge axis 102, and described first hinge axis, 102 built-in return torsion springs 106 are installed lower limit contact block 103 at an end of spacing frame-saw 101;
Upper limit contact block 109 is installed in to rotate on the coupling block 107 and forms assembly;
Second hinge axis 108 is connected in this assembly on the front end cover 114 of retarder;
The first switch slider 104 and second switch slider 110 are housed respectively on the connection box for motor 113, connection box for motor 113 built-in first micro-switch 105 and second micro-switchs 111, the described first switch slider 104 connects described first micro-switch 105, and second switch slider 110 connects described second micro-switch 111.
In this multiple wraps formula steel-wire rope type electric block, motor 122 rotates to drive rope roll 116 by the retarder rope roll 116 that is rotationally connected.This inhibiting device carries out spacing exactly to this electric block, the front end cover 114 of retarder covers on this retarder.
In a further embodiment, this electric block also comprises rope roll 116, suspension hook 118 and steel rope 117, described rope roll 116 is installed on the described spacing framework 101, one side of described rope roll 116 offers through hole, steel rope 117 passes and on described rope roll 116, the lower end of described steel rope 117 is equiped with suspension hook 118 from described through hole.As shown in Figure 3, before steel rope 117 on the rope roll 116 discharges and finishes, need on rope roll 116, to reserve steel rope 117 the 3-4 circle is arranged, and open the hole in rope roll 116 sides, steel rope 117 is passed perforate in the rope roll 116, guarantees that steel rope 117 always is wrapped in 3-4 circle on the rope roll 116, avoid steel rope 117 on rope roll 116 because of fastening not firm, cause weight directly to fall, and major safety risks.
In other embodiment, can stretch in order to make the suspension hook 118 under the steel rope, on described steel rope 117, also be equiped with clump weight 119, described clump weight 119 is positioned at the top of described suspension hook 118.In a further embodiment, on the described spacing framework 101 bossed hyoplastron 121 is set also.
As shown in Figure 4 when transferring weight, when the steel rope 117 on the rope roll 116 also remains 3～4 circles, steel rope 117 is to the close very fast translation of rope roll 116 center positions, the hyoplastron 122 of the spacing frame-saw 101 of steel rope 117 compressings, with first hinge axis 102 is center of circle horizontal hunting, drive lower limit contact block (3) the compressing first switch slider 104 first micro-switch 105 is opened circuit, motor stops operating.Promote weight this moment, and steel rope 117 is to away from rope roll 116 center position translations, and spacing frame-saw 101 and lower limit contact block 103 are got back to original position under the effect of return torsion spring 106, first micro-switch, 105 closures.So realized the lower limit of light-weight electric cucurbit.Owing to set up hyoplastron 122 on spacing frame-saw 101, nearer apart from orlop steel rope 117, under the situation of no-load, steel rope 117 produces when oppositely winding is initial, and steel rope 117 also can be dialled changes spacing frame-saw 101, realizes control, prevents that oppositely winding from continuing to take place.
When suspension hook 118 moves to vertex, the spacing frame-saw 101 of clump weight 119 touchings is not (if there is clump weight 119, then among other embodiment, also can touch spacing framework 101) with suspension hook 118 tops, spacing frame-saw 101 being driven rotate coupling block 107 and upper limit contact block 109, is that the center of circle swings up and down with second hinge axis 108.Upper limit contact block compressing second switch slider 110 opens circuit second micro-switch 111, motor stop motion [meanwhile, lower limit contact block 103 is swing together also, but the first switch slider 104 is not had contention effect, and circuit keeps path].Transfer suspension hook 118 again, spacing frame-saw 101 is retracted original position by return extension spring 112, realizes the upper limit control process of light-weight electric cucurbit.
More than the inhibiting device and the electric block of a kind of multiple wraps formula steel-wire rope type electric block that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
