The beneficial effects of the present invention is: this mechanism's overall structure is simple, cheap, utilizes rope and limited block can meet the detection demand of upper limit and lower limit simultaneously, easy to operate；Lower limit detection switch is arranged on same support with upper limit detection switch, and both close together, reduces the overall volume of mechanism, uses motility strong；It is suitable for the change of jacking equipment height, mechanism's entirety need not be carried out dismounting refitting, reduce operation easier；It is mounted with adjustable limited block so that hook picks and places bigger operation surplus, strong adaptability.
Accompanying drawing explanation
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly, the present invention provides drawings described below to illustrate:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of limited block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As it is shown in figure 1, the jacking equipment extreme position testing agency based on rope in the present invention, including rack body 11, lower limit detection switch 2, upper limit detection switch 3, collision block 4 and limited block 5；Described lower limit detection switch 2 and upper limit detection switch 3 are fixedly installed on rack body 11 and lower limit detection switch 2 is positioned at the upper limit and detects the top of switch 3, and described limited block 5 is arranged on rope 6, and described collision block 4 is sleeved on frame plate 12 and is flexibly connected with frame plate 12.
Frame plate 12 in the present embodiment is vertically fixed on below rack body 11 and collectively forms L-shaped brackets 1 with rack body 11, and collision block 4 is sleeved on rope 6 and activity is plugged on frame plate 12, and limited block 5 is arranged on rope 6 lower end；Limited block 5 has constant weight, and rope 6 is stretched by available deadweight.Support 1 is fixed on the arm of lifting appliance, contacts, with lower limit detection switch 2, the Detection & Controling realizing lower limit by rope 6, coordinate, with contacting between upper limit detection switch 3, the Detection & Controling realizing upper limit by limited block 5, collision block 4.Structure overall simple, can meet the detection demand of upper limit and lower limit simultaneously, due to the close together of lower limit detection switch 2 with upper limit detection switch 3, also can realize installing concentratedly, thus reducing mechanism's overall volume, improve it and using motility.
In the present embodiment, described lower limit detection switch 2 draws together limit switch I 21 and the pulley I 22 being fixedly installed on limit switch I 21；Described upper limit detection switch 3 includes limit switch II 31 and the pulley II 32 being hinged on limit switch II 31.
Concrete, when the rope 6 in lifting appliance is unsettled, limited block 5 in lifting appliance lower end or hang under weight effect, rope 6 is vertically exceptionally straight, rope 6 bear against the pulley I 22 in lower limit detection switch in the horizontal direction, making limit switch I 21 be in connected state, now, staff can control rope by peripheral control unit and transfer.When limited block 5 contacts supporting surface, rope 6 is in relaxation state, and pulley I 22 is not compressed power by rope in the horizontal direction, so that limit switch I 21 is off, now, peripheral control unit cannot control rope 6 again and transfers, it is achieved the lower limit of rope is controlled.
When rope reclaims, owing to binding limited location block 5 below rope 6, when the non-jack-up collision block 4 of limited block 5, upper limit detection is opened 3 passes and is in connected state, and staff can pass through peripheral control unit control rope 6 and reclaim.When after limited block 5 upwards jack-up collision block 4, the collision block 4 of upper shifting can touch the pulley II 32 in upper limit detection switch 3, and the pulley II 32 of rotation disconnects limit switch II 31, makes the peripheral control unit cannot recycling rope, it is achieved the upper limit of rope controls.After rope 6 reaches upper limit, move downward by controlling rope 6, make collision block 4 leave pulley II 32, thus connecting limit switch II 31, now can freely control rope 6 by peripheral control unit and rising or falling.
As the further improvement of such scheme, the detection of described lower limit switchs 2 surfaces being positioned at upper limit detection switch 3 and pulley I 22 is groove pulley with pulley II 32.Rope 32 can be played effect of contraction by groove pulley on direction, improves the reliability of mechanism.
As the further improvement of such scheme, described frame plate 12 is provided with cushion block 7, and described collision block 4 is sleeved in cushion block 7.Cushion block 7 can slow down the frictional impact between collision block 4 and frame plate 12, improves its service life.
As the further improvement of such scheme, described limited block 5 is provided with through hole and lock-screw 8, and described limited block 5 is sleeved on rope 6 by through hole.Concrete, the limited block 5 in the present embodiment region between hook and collision block 4, the limited block 5 position on rope 6 is regulated, it may be achieved lower end hooks into the adjustment of rope lengths between ground, improves its operating flexibility and adaptability by regulating the lock-screw 8 of limited block 5 side.
As the further improvement of such scheme, the locking face of described lock-screw 8 is provided with anti-slip tank, it is possible to decrease lock-screw 8 locks insecure risk.
When rope 6 is chain, can the corresponding structure changing limited block 5, limited block 5 is now not provided with through hole, but crux groove 51, wherein the longest edge groove in crux groove 51 is provided with limited impression 52.As shown in Figure 2.Can changing the limited block 5 position on chain by crux groove 51, chain is then carried out spacing by limited impression 52, it is prevented that it slips down.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
