Shown in Fig. 2,3, the main rope action roller 22, secondary rope 32 balancing activity wheel 43 of action roller are installed in phase
In the sliding rack answered.Since three idler wheels are action roller, it is therefore desirable to be mounted in sliding rack, sliding rack and corresponding C
Type slides bar sliding connection, indirectly idler wheel is driven to slide up and down.Sliding rack is frame structure.
Since the utility model is mounted between winch and track, winch is winding and unreels the power of two main ropes 8
Source, therefore the effect of the utility model primarily serves tensioning and guiding role so that two main ropes 8 and two 9 tensionings of secondary rope, and
And balance the tractive force of two main ropes 8.Existing structure is not compact, takes up a large area, and the spacing between two main ropes 8 is big, and
The spacing very little of track needs to install the bulky receipts that can reduce two 8 spacing of main rope before two 8 injections of main rope
Rope device, therefore by the hard effort of research staff, avoid above-mentioned problem, provides compact-sized, and floor space is small,
And two it is main rope 8 between spacing meet the requirement that can be directly entered track always, without installing rope withdrawing apparatus, directly into
Enter track.
Including the main rope of the utility model two 8, two secondary ropes 9 are in the outside of main rope 8, therefore, preferentially pass through the tensioning of main rope
The rope main to two of device 28 is tensioned, and when tensioning, two main ropes 8 sequentially pass through that spaced apart three groups main ropes are fixed to be rolled respectively
Wheel 21 and two groups of main rope action rollers 22, main rope fixed idler whell 21 primarily serves main restrict of positioning and 8 acts on, and main rope action roller 22
Main 8 effect of rope of tensioning is primarily served by main rope tensioning block 23.At this point, two secondary ropes 9 are located at the two of main rope tensioning apparatus 2
Side.
Two secondary ropes 9 are tensioned by pair rope tensioning apparatus 3 again, two secondary ropes 9 sequentially pass through arranged for interval respectively
Three groups of pair rope fixed idler whells 31 and two groups of pair rope action rollers 32, pair rope fixed idler whell 31 primarily serve secondary 9 effect of rope of positioning,
And secondary rope action roller 32 primarily serves secondary 9 effect of rope of tensioning by pair rope tensioning block 33.And it is tensioned to two secondary ropes 9
When, two main ropes 8 also pass through the main rope stabilizer group 4 in secondary rope tensioning apparatus 3, and the effect of main rope stabilizer group 4 is to two
The tractive force of main rope 8 is adjusted so that the tractive force of two main ropes 8 reaches balance.Two main ropes 8 pass through removable accordingly
Two balancing activity wheels 43, two balancing activity wheels 43 are connected by balance rope 42, when wherein one 8 tractive force mistakes of main rope
Greatly, it will be transmitted on another balancing activity wheel 43 so that another 8 corresponding stress of main rope.
Great progress has also been made on compact-sized, using a combined type mounting bracket 1, and is installed separately main rope tensioning dress
Set 2 and secondary rope tensioning apparatus 3 minimized while combined type mounting bracket 1 meets installation requirements, ensure between two main ropes 8
Away from track can be can smoothly enter into.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
