Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out
Explanation：
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of limited block.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figure 1, the jacking equipment extreme position testing agency based on rope in the present invention, including rack body
11st, lower limit detection switch 2, upper limit detection switch 3, collision block 4 and limited block 5；The 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 located at the top of upper limit detection switch 3, and the limited block 5 is set
On rope 6, the 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 the lower section of rack body 11 and collectively forms L-shaped with rack body 11
Support 1, collision block 4 is sleeved on rope 6 and activity is plugged on frame plate 12, and limited block 5 is arranged on the lower end of rope 6；Limited block 5 has
There is constant weight, stretch rope 6 using deadweight.Support 1 is fixed on the arm of lifting appliance, by rope 6 with
Limit detection switch 2 contacts the Detection ＆ Controling for realizing lower limit, passes through connecing between limited block 5, collision block 4 and upper limit detection switch 3
It is tactile to coordinate the Detection ＆ Controling for realizing upper limit.Structure overall simple, the detection demand of upper limit and lower limit can be met simultaneously,
It is closer to the distance due to lower limit detection switch 2 and upper limit detection switch 3, it can also realize and install concentratedly, so that it is whole to reduce mechanism
Body volume, improves it and uses flexibility.
In the present embodiment, the lower limit detection switch 2 includes limit switch I 21 and is fixedly installed on limit switch I 21
Pulley I 22；The upper limit detection switch 3 includes limit switch II 31 and the pulley II 32 being hinged on limit switch II 31.
Specifically, when the rope 6 in lifting appliance is hanging, limited block 5 or suspension weight in lifting appliance lower end are made
Under, rope 6 is vertical exceptionally straight, and rope 6 bear against the pulley I 22 in lower limit detection switch in the horizontal direction, make limit switch I
21 are in connected state, and now, staff can control rope to transfer by peripheral control unit.Supported when limited block 5 is contacted
During face, rope 6 is in relaxation state, and rope does not compress power to pulley I 22 in the horizontal direction, so that limit switch I 21
It is off, now, peripheral control unit can not control rope 6 to transfer again, realizes and the lower limit of rope is controlled.
When rope is reclaimed, due to the lower section of rope 6 binding limited location block 5, in the non-jack-up collision block 4 of limited block 5, upper limit detection
Open 3 passes and be in connected state, staff can control rope 6 to reclaim by peripheral control unit.When the upward jack-up collision block of limited block 5
After 4, the collision block 4 moved up can touch the pulley II 32 in upper limit detection switch 3, and the pulley II 32 of rotation disconnects limit switch II
31, make peripheral control unit can not recycling rope, realize rope upper limit control.After rope 6 reaches upper limit, pass through control
Rope making rope 6 is moved downward, and collision block 4 is left pulley II 32, so as to connect limit switch II 31, can now pass through peripheral control unit
Rope 6 is freely controlled to rise or fall.
As the further improvement of such scheme, the lower limit detection switch 2 be located at the surface of upper limit detection switch 3 and
Pulley I 22 and pulley II 32 are groove pulley.Groove pulley can play effect of contraction on direction to rope 32, improve mechanism
Reliability.
As the further improvement of such scheme, the frame plate 12 is provided with cushion block 7, and the collision block 4 is sleeved on cushion block 7
It is interior.Cushion block 7 can slow down the frictional impact between collision block 4 and frame plate 12, improve its service life.
As the further improvement of such scheme, the limited block 5 is provided with through hole and lock-screw 8, the limited block 5
It is sleeved on by through hole on rope 6.Specifically, the limited block 5 in the present embodiment is located at the region between hook and collision block 4, lead to
Overregulate the lock-screw 8 of the side of limited block 5 to adjust position of the limited block 5 on rope 6, achievable lower end hooks into ground
Between rope lengths regulation, improve its operating flexibility and adaptability.
As the further improvement of such scheme, the locking face of the lock-screw 8 is provided with anti-slip tank, it is possible to decrease locking
Screw 8 locks insecure risk.
When rope 6 is chain, the structure for changing limited block 5 can be corresponded to, now through hole is not provided with limited block 5, and
It is crux groove 51, wherein the longest edge groove in crux groove 51 is provided with limited impression 52.As shown in Figure 2.It is logical
Position of the limited block 5 on chain can be changed by crossing crux groove 51, and limited impression 52 is then spacing to chain progress, prevents it
Slip down.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
