Adjacent perforation 282a is corresponding, the upper and lower position so as to being incorporated into first riser 282 for adjusting first shield 32.This
One shield 32 is hubbed in the first support 28 by a pivot by taking bolt 38 as an example.In addition, the stand of the first shield first
The pivot swinging of first shield 32 is more fixed by a fixture 40 and pivot puts position.More specifically, the fixture 40 wraps
A bolt 402 and a baffle plate 404 are included, the bolt 402 has the head of a butterfly, and the baffle plate 404 has two screw 404a.As
The bolt 38 of pivot locks the one of the baffle plate 404 screw through the perforation 282a and pivoted hole 322a of the first riser 282
404a, and the bolt 38 has the head of a butterfly；The bolt 402 of the fixture 40 passes through another perforation 282a and the arc
Hole 322b and lock another screw 404a of the baffle plate 404, and the head of two bolt 38,402 is available for personnel's turn so that
Two bolt 38,402 head and the baffle plate 404 clamp first riser 282 and the side plate 322 jointly, and fix this first
The pivot pendulum position of shield 32.After two bolt 38,402 is unscrewed, you can pivot puts first shield 32.
The structure of second shield 34 is similar with first shield 32, same to have at least side plate 342, in the present embodiment
In for two side plates 342, respectively there is the side plate 342 an a pivoted hole 342a and arcuate socket 342b, pivoted hole 342a to be located at the arc
The shape hole 342b center of curvature and to should be on the second riser 302 wherein one perforation 302a, arcuate socket 342b corresponds to another
Perforation 302a.
Second shield 34 by least one pivot by taking bolt 42 as an example and an at least fixture 44 and be hubbed at this
On two supports 30, bolt 42 and the quantity of fixture 44 are two in the present embodiment, and respectively the fixture 44 includes a bolt 442 and a gear
Plate 444, foregoing combination is identical with the combination of the first shield 32, and appearance does not repeat.Those bolts 42,442 are equally
Lock in two screw 444a of the respectively baffle plate 444, and the head of bolt 42,442 and respectively the baffle plate 444 jointly clamping respectively this second
Riser 302 and the respectively side plate 342, and fix the pivot pendulum position of second shield 34.After those bolts 42,442 are unscrewed, you can
Pivot puts second shield 34.
First shield 32 is with second shield 34 can be connected in a manner of relative telescopic.First shield 32 with this second
Shield 34 is in elongated, and one of them is located at another inner side, and in the present embodiment, first shield 32 is located at second shield
34 inner side, but be not limited.First shield 32 is with second shield 34 by least stationary phase of a fixture 46 to stretching
The position of contracting, more specifically, respectively side plate 322 of first shield 32 are axially extending along its length with an elongated hole 322c,
Respectively side plate 342 of second shield 34 also has an elongated hole 342c axially extending along its length.Respectively the fixture 46 is included extremely
Few pilot pin and a baffle plate 464 by taking bolt 462 as an example, the quantity of an at least bolt 462 is two and respectively in the present embodiment
Not Ju You butterfly head, respectively the screw 464a of the baffle plate 464 quantity also be two.Those bolts 462 pass through second shield
Cover 34 elongated hole 342c and the elongated hole 322c of the first shield 32 and lock the screw 464a of two baffle plate 464 respectively, and respectively
The head of the bolt 462 and the respectively baffle plate 464 clamp first shield 32 and second shield 34 jointly, to fix first shield
The position of cover 32 and the relative telescopic of the second shield 34.After those bolts 462 are unscrewed, you can make first shield 32 with this
The relative telescopic of two shield 34, bolt 462 and elongated hole 322c, 342c, which coordinates, can also limit flexible distance, avoid first shield
Cover 32 excessively stretches out and departs from second shield 34.
From above-mentioned explanation, the adjustable cable wire guard shield device 26 can not only adjust first shield 32 with
The flexible length of second shield 34, it also can adjust the position of first shield 32 and the pivot of the second shield 34 pendulum.In addition, those
Bolt 38,42 and those fixtures 40 pivotally, 44,46 is detachable, make first shield 32 and the first support 28 it
Between, between second shield 34 and the second support 30 and between first shield 32 and second shield 34, that relative can tear open
From more convenient workmen transports and assembling.The advantages of passing through elongated hole 322c, 342c using two bolts 462 be, two
Bolt 462 can form two strong points in elongated hole 322c, 342c, avoid first shield 32 and the phase of the second shield 34
To bending.
Fig. 6 be the adjustable cable wire guard shield device 26 with the present embodiment another lowering or hoisting gear 200 ', its with
The difference of Fig. 5 lowering or hoisting gear 200 is, Fig. 6 main wheel of lowering or hoisting gear 200 ' 224 and displacement wheel 24 it is closer to the distance, therefore,
The length stretched by adjusting first shield 32 with second shield 34, and adjust first shield 32 and second shield 34
Pivot pendulum position, allow the present embodiment adjustable cable wire guard shield device 26 go for main wheel 224 with displacement wheel 24 away from
From different lowering or hoisting gears 200,200 '.
Fig. 7 and Fig. 8 show the adjustable cable wire guard shield device 50 of second preferred embodiment of the invention, and it has big
Cause to be same as the structure of first embodiment, equally comprising a first support 52, a second support 54, one first shield 56 and 1 the
Two shields 58, unlike, there are the side plate 562 of first shield 56 multiple perforation 562a to be axially spaced along its length respectively
Set.The elongated hole and first of second shield 58 is passed through by the pilot pin by taking an at least bolt 602 as an example of each fixture 60
On each side plate 562 of shield 56 those perforation 562a among one and lock in the screw 604a of baffle plate 604.In the present embodiment,
The respectively perforation 562a on the side plate 562 of first shield 56 quantity is more than three, and two bolts 602 of each fixture 60
It is each passed through adjacent the two among those perforation 562a.The head of bolt 602 and baffle plate 604 clamp jointly first shield 56 with
Second shield 58, to fix the position of first shield 56 and the relative telescopic of the second shield 58.In fact, the second shield 58
Also elongated hole 582 can be not provided with, allows bolt 602 directly to wear the second shield 58, as long as in this way, adjusting the position of first shield 56
Put, allow bolt 602 to pass through different perforation, you can change the first shield 56 length relative with the second shield 58.In addition, also may be used
In being axially arranged at intervals multiple perforation along long on the second shield 58.
Mentioned above, adjustable cable wire guard shield device of the invention can be by adjusting first shield and second shield
The flexible length of cover, and the position of first shield and the second shield pivot pendulum is adjusted, and can be universally used in main wheel and displacement wheelspan
From different a variety of lowering or hoisting gears, without developing special cable wire guard shield for each falling unit, design is effectively reduced
And the cost of manufacture.
Preferably possible embodiments of the invention are the foregoing is only, as long as using description of the invention and claim institute
For equivalence changes, ought to be included in the present invention scope of patent protection in.
