Device for pulling out Pedertiägelu aas

Biaanbalma swell "

The discovery concerns a device auia Ausssiehen v (m

aas railway sleepers »1t one on the sleeper and the

on top rail abs does abs? eü hydrauliecheia winch, on

which can be attached to a spring nailer designed as an additional device

A well-known Pedemagelr.iefaer is screwed to a winch and has a semicircular horizontal pull

bolaen, which grips under the feather nail »For this, an intermediate · There should be space between the rail and the spring nail, wai is not always the case

The invention has an additional device for the goal, which comprises the spring nail from the side by clamping. This object is achieved in that the spring nail puller has a mounted in a holder Hemmbaokönpaar, and that a ά for actuating, ύτ jaws serving expanding part guided in the holder and hängbar.ist on the winch _"β The inventively constructed device has the advantage that is not damaged during its Anwandung the spring nail, no fissure in particular and not bending _i It is also not necessary to bring the hail head with a hammer in a convenient pull-out position, "rather, the device can even with flat beaten spring heads without special preparation of the hail to be extracted "

The holder can encompass the pair of clasps in a U-shape and serve to guide the expansion piece, creating a self-contained GEDHUi: GSlTES device. The secluded from small Raab section in & s of Klerarabackenpaareg form a wedge-shaped, upward look constrict "the 3aum _s' engages in the the expanding part with its spreading through this training can be relatively exert large forces on the Uagel in a development of Srfindungegegenatandes, with the jaws of Push the starting point under the hail and first release it from its position. This first loosening is known to require the greatest effort because the existing between hail and emerging connection Rauss be relaxed first _e Each dea loosening are only existing between the hail and the threshold Heibungsfcräftö to overcome that "if can be large relatively" but just

In the drawing is an exemplary embodiment of the object of the invention shown. .ISs show

Fig * 1 is a side view,
Fig. 2 is a front view,
Figo 3 shows a rope cut along line III-III in Fig «, p.

A hydraulic winch 1 has a plunger 3 with a barrel 7 specially designed to be placed on a railroad tie 5 and a lifting cylinder 9. A handle 11 is attached to the lifting cylinder 9 _f to which a pump, not shown, is connected, which can be operated by swiveling the hand lever 13 and delivers pressure medium into the working space formed between the lifting cylinder 9 and the plunger 3 »A pressure medium drain screw 19 is attached to the ^{lifting cylinder 1 *}

* On the lifting cylinder 9 is a hook formed from two legs

* attached, the one to receive a part of the spring nail puller serves «, on the stamp 3 is height adjustable one with awei wings provided Auflageatiick 23 attached, which is on a rail 25 and supported on its side · The rail 25 is fastened to the sleeper 5 with the aid of a spring nail 27

The Fe ernagelzieher has a misshapen holder _s der.aus two

side plates 31 and 32 and a Kittelstliok 33 ^s is formed * In the plates 31 and 32 are two bolts 35 and 3? attached * ^L on each of which a clamping jaw 38 and 39 is mounted i3t _s their from ] the holder 31 to 33 protruding section to the side

Gripping on a spring nail is designed in the shape of a hook and: its section which is remote from the clamping section and is adjacent to the other clamping jaws! The middle rail is inclined in such a way that both jaws are always

If- ■ '

delimit a wedge-shaped space 40 *. An expansion section 41 of an expansion piece engages in this space and consists of a cylinder section arranged coaxially with the bolts 35 and 37. A rod 42, which is passed through the middle section 33 of the holder, is connected to this at its free end a cross bar 43 carries ₉ to the from the

* Holders 31 to 33 exposed section of the rod 42 is

f with the help of a transverse pin 45 a collar 47 is attached «between

T the Hittelabschnitt 33 of the holder und.dem collar 47 is a

1 spring 49 clamped, which strives to expand the expansion section 41

* to look outwards _s thereby creating the clamping sections
