Description
Technical field
The utility model relates to a kind of balancing device, particularly about a kind of three groups of steel rope automatic balance devices.
Background technology
Steel rope is original paper important in lifting means, lifting thing is provided with mostly and organizes suspension centre more, steadily reliable when ensureing to be promoted thing lifting.When adopting many group reels by when the wire rope roll organized on suspension centre on reel more, individual layer wiring can be relatively more neat, and now many group steel ropes are simultaneously stressed; Along with the increase of the number of plies that each reel connects up, on reel, on each wiring layer, the number of turns of Wound steel rope can change, cause the winding radius on each reel on steel rope to vary in size, the steel rope on the reel that such winding radius is maximum is stressed separately, and all the other steel ropes do not stress; When on reel, single group steel rope is stressed, can not smooth running by lifting thing, and the security requirement that system uses can not be met.
Summary of the invention
For the problems referred to above, it is good that the purpose of this utility model is to provide a kind of safety performance, can realize steel rope self-balanced three groups of steel rope automatic balance devices flexibly.
For achieving the above object, the utility model is by the following technical solutions: a kind of three groups of steel rope automatic balance devices, it is characterized in that: it comprises a framework, on described framework, interval is fixedly installed three tracks, track described in each is respectively arranged with a slotted hole, a running block is provided with slidably in slotted hole described in each, the top of running block described in each arranges a movable pulley respectively, the bottom of the described running block of both sides arranges a movable pulley respectively, and the bottom of middle described running block arranges an anchor shaft; The framework of rail base described in both sides arranges a fixed pulley respectively, the framework of middle described rail base is arranged a fixed pulley and an anchor shaft.
Described framework bottom is fixedly connected with two pieces of transverse slats, and two pieces of described transverse slats connect the described fixed pulley of both sides, middle described fixed pulley and anchor shaft, and the bottom of three described tracks.
Described framework upper is fixedly connected with two pieces of transverse slats, and three described track tops are fixedly connected on transverse slat described in two.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model in the frame spaced three tracks in portion is respectively arranged with a slotted hole, slide in three slotted holes and three running blocks are set, three running blocks can be realized and move up and down.2, the utility model steel cable is fixedly connected on the anchor shaft of middle running block bottom, then steel rope is walked around successively the fixed pulley on its lower square bearer downwards; Upwards walk around the fixed pulley of fixed pulley group lower end, side; Walk around the fixed pulley on square bearer under this side fixed pulley downwards; Level walks around the fixed pulley under opposite side on square bearer; Upwards walk around the fixed pulley of this fixed pulley group lower end, side; Downwards by another anchor shaft on lower square bearer of the end winding support of this steel rope, and the length of steel rope is certain value; Three groups of steel rope correspondences of lifting are enclosed within the movable pulley on three fixed pulley group tops; Can realize a running block when moving up in slotted hole, two other running block moves down, and realizes three groups of steel ropes simultaneously stressed, and can realize three groups of stressed self-balanced objects of steel rope.3, the utility model due to the stressed size of steel rope on the movable pulley of middle running block be two running blocks of both sides movable pulley on the stressed half of steel rope, so can using the steel rope on the movable pulley of middle running block as the safety rope promoting object.4, simple, the good economy performance of the utility model structure, be easy to realize.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a framework 1, and on framework 1, interval is fixedly installed three tracks 2, each track 2 is respectively arranged with a slotted hole 3.Be provided with a running block 4 in each slotted hole 3 slidably, the top of each running block 4 arranges a movable pulley 5 respectively, and the bottom of the running block 4 of both sides arranges a movable pulley 6 respectively, and the bottom of middle running block 4 arranges an anchor shaft 7.Correspondingly, the framework 1 bottom two siding tracks 2 is arranged respectively a fixed pulley 8, and framework 1 bottom intermediate orbit 2 arranges fixed pulley 9 and an anchor shaft 10.
Steel cable 11 is fixedly connected on the anchor shaft 7 of middle running block 4 bottom, then steel rope 11 is walked around successively the fixed pulley 9 on its lower square bearer 1 downwards; Upwards walk around the fixed pulley 6 of fixed pulley group 4 lower end, side; Walk around the fixed pulley 8 on this side fixed pulley 6 times squares bearer 1 downwards; Level walks around the fixed pulley 8 under opposite side on square bearer 1; Upwards walk around the fixed pulley 6 of this fixed pulley group 4 lower end, side; Downwards by another anchor shaft 10 on lower square bearer 1 of the end winding support of this steel rope 10.Finally three groups of steel rope 12 correspondences of lifting are enclosed within the movable pulley 5 on three fixed pulley group 4 tops.
In above-described embodiment, two pieces of transverse slats 13 can be fixedly connected with in lower frame 1, two pieces of transverse slats 13 connect the fixed pulley 8 of both sides, middle fixed pulley 9 and anchor shaft 10, and the bottom of three tracks 2.
In above-described embodiment, two pieces of transverse slat (not shown)s can also be fixedly connected with on upper frame, three track 2 tops are fixedly connected on two transverse slats.
When the utility model uses, during if there is three groups of steel rope 12 discontinuity, due to the effect of steel rope 11, if a running block 4 is stressed larger, this running block 4 will move up, and other two running block 4 will move down, and then it is simultaneously stressed to realize three groups of steel ropes 11, that is achieves the stressed self-balanced object of the utility model three groups of steel ropes 12.
In the middle of the utility model running block 4 movable pulley 5 on the stressed size of steel rope 12 be two running blocks 4 of both sides movable pulley 5 on the stressed half of steel rope 12, can using the steel rope 12 on the movable pulley 5 of middle running block 4 as the safety rope promoting object.The range that three groups of steel ropes 12 can balance is the half of slotted hole 3 length, and the stroke that three groups of steel ropes 12 can balance depends on the length of slotted hole 3.
The various embodiments described above are only for illustration of the utility model; wherein the structure of each parts, connection mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
