Description

【０００１】
【発明の属する技術分野】
本発明は、クレーンのウインチ等の装置に巻き取る新しいワイヤーロープに張力負荷を与える装置に関する。
【０００２】
【従来の技術】
クレーンのウインチ等に新しいワイヤーロープを巻き取ったり巻き替えるに際し、新しいワイヤーロープは木製等のドラムに巻かれており、そのワイヤーロープの端部をクレーンのウインチにセットしてウインチの回転力によって巻き取るものであるが、その巻き取りの際に、ワイヤーロープに張力負荷をかけ、巻き取らせるウインチ地巻き部分の巻きをウインチドラムに密着させるために新しいワイヤーロープの初期の伸びを取りながら巻き取ることが重要である。それによってクレーン作業時のワイヤーロープの割り込み等のワイヤートラブルを未然に防ぐことができる。そのためにワイヤーロープに張力負荷を与え、そのワイヤーロープをクレーンのウインチに順序よくきっちりと詰めた状態で硬く巻き取ることが要求される。
【０００３】
そのためには例えば、直径３０ｍｍのような太い径のワイヤーロープではその張力負荷は１０ｔ以上が要求される。
【０００４】
【発明が解決しようとする課題】
このような従来技術によると、引き出されるワイヤーロープの大きな負荷がかかるために、大きな制動力で木製のドラムの回転を制御するものであるが、その張力負荷により、木製等のドラムに数段の重層状態に巻いてあるワイヤーロープの下の層に上の層の引き出されるワイヤーロープが割り込んで乱巻き状態となってしまい、ワイヤーロープに傷を付ける問題が生じ、ひどい場合にはその割り込みが強固で巻き出し不能の固着状態となる問題がある。
【０００５】
また、大きな制動力で木製のドラムを制動し、しかも大きな張力負荷で引張するために木製等のドラムが破壊してしまうこともあり、これによって巻き出し不能となる問題もある。
さらに、ウインチに十分な引張力で巻き取ることができないために、ウインチにしっかりと硬く巻き取れずにずるずるの状態になってしまう問題がある。
【０００６】
【課題を解決するための手段】
そこで本発明は、内側面に螺旋羽根を複数回設けて螺旋溝を形成すると共にワイヤーロープの供給口と排出口を設けた外筒に内筒を嵌め、この内筒の少なくとも一側にブレーキディスクやブレーキシュー等の被制動体を設け、内筒の回転軸を軸受け台に回転可能に支持すると共に前記被制動体を介して制動装置により制動可能とし、外筒を装置本体に固定したことを特徴とする。
【０００７】
【発明の実施の形態】
以下に本発明の実施の形態例を図面を用いて説明する。
図１は全体説明図、図２は要部断面図、図３は要部解体斜視図、図４は外筒の断面説明図であり、図において、１は木製等のドラムであり、回転テーブル２に回動可能にセットしてある。この回転テーブル２は図示しない回転制御装置によって回転制御される。
【０００８】
３はこの木製等のドラム１に巻かれているワイヤーロープである。
５は制御ドラムであり、以下に説明する如く、内筒６と外筒７によって構成されている。
内筒６は、両側が閉じた筒体であり、その軸方向の中心に回転軸８があり、一側に係止用のフランジ９が形成されており、さらに両側もしくは一側にブレーキディスクもしくはブレーキシュー等の被制動体１０が設けてある。
【０００９】
外筒７は、上記内筒６を嵌めて覆う径を有し、内側面に螺旋羽根１１を複数回設けて螺旋溝１２を形成し、筒本体にワイヤーロープ３を螺旋溝１２に導く供給口１３と排出口１４が形成されている。
上記内筒６をこのようにした外筒７に嵌め、内筒６の端部に係止フランジ１５を取り付けてこの係止フランジ１５とフランジ９との間で外筒７が外れないように位置させる。
【００１０】
なお、この内筒６外周面と外筒７の螺旋羽根１１との隙間はワイヤーロープ３が通ることがない間隙としておく。
このような状態にして内筒６と外筒７とを組み合わせ、内筒６の回転軸８を軸受け台１６に支持させて回動可能にし、図示しない制動装置を被制動体１０に接続し、外筒７は係止部１７によって装置本体に固定状態とする。
【００１１】
このようにして組み立てられた制御ドラム５は、木製等のドラム１からワイヤガイド１８によって案内されたワイヤーロープ３をその供給口１３から挿入し、内筒６外周面に外筒７の螺旋溝１２に沿って巻き付けて排出口１４から出し、その先端を図示しないクレーンのウインチにセットする。
このようにセットされたワイヤーロープ３をクレーンのウインチに巻き取るものであるが、その際に、木製等のドラム１を制動させると共に制御ドラム５の内筒６を被制動体１０を介して制動させ、しかも木製等のドラム１からのワイヤーロープ３にかかる引張力Ａの方が制御ドラム５からのワイヤーロープ３にかかる引張力Ｂより小さく、ウインチの引張力を制御ドラム５が受けてウインチの引張力が木製等のドラム１に直接伝わらないようにしてある。
【００１２】
これは、制御ドラム５の内筒６に適正な制動を与えることにより、ウインチの引張力に対して、内筒６に数回巻き付けられたワイヤーロープ３は、その内筒６外周面との接触摩擦により一次の張力が発生する。
さらに、そのワイヤーロープ３は、外筒７の螺旋溝１２のねじの原理によって内筒６の回転に従って順次円滑に送られて行くが、その際に、固定されている螺旋羽根１１との接触摩擦によって二次の張力が発生する。
【００１３】
この一次および二次の接触摩擦によってウインチの引張力に対して大きな張力となってウインチに順序よくきっちりと密着した状態で硬く巻き取らせることができることになる。しかも、このウインチの引張力は制御ドラム５によって木製等のドラム１に伝わらないためにワイヤーロープ３を木製等のドラム１の重層に巻いてある下の層に割り込ませることがない。
【００１４】
したがって、制御ドラム５によるワイヤーロープ３の制動作用は、制御ドラム５の内筒６の制動能力は無論のこと制御ドラム５の内筒６の巻回数および外筒７の螺旋羽根１１に接触する長さが制動作用の大きな要因となる。
なお、必要に応じて、ワイヤーロープ３を内筒６に直ちに密着させるために、図１および図５に示す如く、外筒７の供給口１３の螺旋溝１２の途中にワイヤー押さえローラ１９を設けることにより、押さえローラ１９はワイヤーロープ３を内筒６外周面に密着させるもので、木製等のドラム１からの供給速度に変化があってもこの押さえローラ１９によって一定に保った状態で内筒６外周面に密着させることができる。
【００１５】
この押さえローラ１９の設置は、例えば図５に示す如く、外筒７に開口２０を設けてその開口２０から押さえローラ１９の一部を螺旋溝１２内に突出させる構造で、押さえローラ１９を取り付けた支持材２１の一端を外筒７に回動可能に取り付け、他端を外筒７に係止具２２によって係止可能にし、この係止具２２によって支持材２１の端部を押圧して押さえローラ１９の押圧力を調整できるようにしておくとよい。
【００１６】
以上説明した制御ドラム５の内筒６および外筒７は両端まで同一寸法の筒体であるが、必ずしもこのような筒体である必要はなく、例えば図６に示す外筒の如く、円錐台形でもよく内筒はそれに合わせた形状にすればよく、さらには、図７に示す外筒の如く、すぼまった円錐台形のようなものでもよくその内筒もそれに合わせた形状にすればよい。
【００１７】
また、上記の説明では外筒は一体の筒体として説明したが、軸方向に２分割した分割構造（図４のような分割したものを組み合わせる構造。）でもよく、分割した場合には、両端部は強固に係止されるが、その係止状態は例えば、その一側の連結部はヒンジで回動可能に連結し、他側は互いに係止連結する構造や両連結部共に係止連結する構造としておけばよい。このように分割構造にすると、外筒を開放した状態が得られるためにワイヤーロープの制御ドラム５への装着が容易になり、また、中央がすぼまった鼓状のような形状の内筒でも外筒を装着することができることになる。
【００１８】
なお、以上の各説明はクレーンのウインチにワイヤーロープを巻き取る場合で説明を行ったが、必ずしもクレーンのウインチに限るものではなく、ワイヤーロープを巻いてあるドラムから巻き戻して他のウインチに巻き取る場合のどのような場合においても上記同様に有効なものである。
【００１９】
【発明の効果】
以上詳細に説明した本発明によると、内側面に螺旋溝を形成すると共にワイヤーロープの供給口と排出口を設けた外筒に内筒を嵌め、この内筒を回動可能に支持すると共に制動手段に連結し、外筒を装置本体に固定したことにより、供給口より供給されて内筒に巻かれたワイヤーロープは、回転が制御されている内筒の外周面との接触摩擦と螺旋溝との接触摩擦の両方の接触摩擦によって大きな引張力を得ることができ、これによってワイヤーロープの初期の伸びを取り去って順序よくきっちりと詰めた状態で硬くウインチに巻き取ることができる効果を有する。
【００２０】
このようにウインチに硬く巻き取ることができることにより、ウインチから繰り出されたワイヤーロープに大きな張力が作用してもウインチに重層されている層の中にワイヤーロープが割り込むことがないという効果となる。
また、巻き取り側の引張力はワイヤーロープが巻いてある木製等のドラムには伝わらないために、ワイヤーロープが重層状態に巻かれているワイヤーロープ間に割り込んで乱巻き状態になったり、固着状態となってしまうことがなくなる効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a device for applying tension load to the new wire rope wound into device winches etc. crane.
[0002]
[Prior art]
When winding or rewinding a new wire rope on a crane winch, etc., the new wire rope is wound around a wooden drum, and the end of the wire rope is set on the crane winch and wound by the rotational force of the winch. When winding, apply tension load to the wire rope and wind it while taking up the initial elongation of the new wire rope so that the winding of the winch ground winding part to be wound closely adheres to the winch drum This is very important. As a result, wire troubles such as interruption of the wire rope during crane work can be prevented in advance. For this purpose, it is required to apply a tension load to the wire rope, and to wind the wire rope tightly in a state where it is tightly packed in the crane winch.
[0003]
For that purpose, for example, a thick wire rope having a diameter of 30 mm requires a tension load of 10 t or more.
[0004]
[Problems to be solved by the invention]
According to such a conventional technique, since a large load is applied to the drawn wire rope, the rotation of the wooden drum is controlled with a large braking force. The wire rope that is pulled out by the upper layer of the wire rope that is wound in a multi-layered state interrupts the wire rope, causing a problem of damaging the wire rope. In severe cases, the interruption is strong. There is a problem that it becomes a fixed state that cannot be unwound.
[0005]
In addition, the wooden drum is braked with a large braking force and pulled with a large tension load, so that the wooden drum or the like may be broken, which makes it impossible to unwind.
Further, since the winch cannot be wound with a sufficient tensile force, there is a problem that the winch is not firmly wound on the winch and is in a state of slipping.
[0006]
[Means for Solving the Problems]
Accordingly, the present invention provides an inner cylinder fitted to an outer cylinder in which spiral blades are provided a plurality of times on the inner surface to form a spiral groove and a wire rope supply port and discharge port are provided, and a brake disk is provided on at least one side of the inner cylinder. and the object braking body such as brake shoes provided to allow braked by the braking device via the object braking body while rotatably supporting the rotary shaft of the inner cylinder in the cradle axis, the outer cylinder to the apparatus main body It is characterized by being fixed.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 is a general explanatory view, FIG. 2 is a cross-sectional view of a main part, FIG. 3 is a perspective view of a main part disassembly, FIG. 4 is a cross-sectional explanatory view of an outer cylinder, and in the figure, 1 is a drum made of wood or the like. 2 is set to be rotatable. The rotation table 2 is rotationally controlled by a rotation control device (not shown).
[0008]
3 is a wire rope wound around the drum 1 of the wood and the like.
A control drum 5 includes an inner cylinder 6 and an outer cylinder 7 as described below.
The inner cylinder 6 is a cylinder closed on both sides, and has a rotating shaft 8 at the center in the axial direction. A locking flange 9 is formed on one side, and a brake disc or A braked body 10 such as a brake shoe is provided.
[0009]
The outer cylinder 7 has a diameter to which the inner cylinder 6 is fitted and covered, a spiral blade 11 is provided a plurality of times on the inner surface to form a spiral groove 12, and a supply port for guiding the wire rope 3 to the spiral groove 12 in the cylinder body 13 and a discharge port 14 are formed.
The inner cylinder 6 is fitted to the outer cylinder 7 as described above, and a locking flange 15 is attached to the end of the inner cylinder 6 so that the outer cylinder 7 does not come off between the locking flange 15 and the flange 9. Let
[0010]
The gap between the outer peripheral surface of the inner cylinder 6 and the spiral blade 11 of the outer cylinder 7 is set so that the wire rope 3 does not pass through.
In such a state, the inner cylinder 6 and the outer cylinder 7 are combined, the rotating shaft 8 of the inner cylinder 6 is supported by the bearing base 16 to be rotatable, a braking device (not shown) is connected to the braked body 10, The outer cylinder 7 is fixed to the apparatus main body by the locking portion 17.
[0011]
In the control drum 5 assembled in this way, the wire rope 3 guided by the wire guide 18 from the wooden drum 1 is inserted through the supply port 13, and the spiral groove 12 of the outer cylinder 7 is formed on the outer peripheral surface of the inner cylinder 6. And the tip is set on a winch of a crane (not shown).
The wire rope 3 set in this way is wound around the winch of the crane. At that time, the drum 1 made of wood or the like is braked and the inner cylinder 6 of the control drum 5 is braked via the braked body 10. Moreover, the tensile force A applied to the wire rope 3 from the wooden drum 1 is smaller than the tensile force B applied to the wire rope 3 from the control drum 5, and the control drum 5 receives the tensile force of the winch and the winch The tensile force is not transmitted directly to the wooden drum 1 or the like.
[0012]
This is because, by applying appropriate braking to the inner cylinder 6 of the control drum 5, the wire rope 3 wound around the inner cylinder 6 several times in contact with the outer peripheral surface of the inner cylinder 6 against the tensile force of the winch. Primary tension is generated by friction.
Further, the wire rope 3 is smoothly fed sequentially according to the rotation of the inner cylinder 6 according to the screw principle of the spiral groove 12 of the outer cylinder 7, but at that time, the contact friction with the fixed spiral blade 11 Due to this, secondary tension is generated.
[0013]
Due to the primary and secondary contact friction, the tension becomes large with respect to the tensile force of the winch, so that the winch can be wound tightly in order in close contact with the winch. Moreover, since the tensile force of the winch is not transmitted to the wooden drum 1 by the control drum 5, the wire rope 3 is not interrupted by the lower layer wound around the multilayer of the wooden drum 1.
[0014]
Therefore, the braking action of the wire rope 3 by the control drum 5 is not limited to the braking ability of the inner cylinder 6 of the control drum 5, and the length of contact with the number of turns of the inner cylinder 6 of the control drum 5 and the spiral blade 11 of the outer cylinder 7 is long. Sag is a major factor in braking action.
If necessary, a wire pressing roller 19 is provided in the middle of the spiral groove 12 of the supply port 13 of the outer cylinder 7 as shown in FIGS. 1 and 5 in order to immediately attach the wire rope 3 to the inner cylinder 6. Thus, the pressing roller 19 is used to bring the wire rope 3 into close contact with the outer peripheral surface of the inner cylinder 6, and even if there is a change in the supply speed from the drum 1 made of wood or the like, the inner cylinder is kept constant by the pressing roller 19. 6 It can be made to stick to the outer peripheral surface.
[0015]
For example, as shown in FIG. 5, the pressing roller 19 is provided with an opening 20 in the outer cylinder 7 so that a part of the pressing roller 19 protrudes into the spiral groove 12 from the opening 20. One end of the support member 21 is pivotally attached to the outer cylinder 7, and the other end can be locked to the outer cylinder 7 by a locking tool 22, and the end of the supporting material 21 is pressed by the locking tool 22. It is preferable that the pressing force of the pressing roller 19 can be adjusted.
[0016]
The inner cylinder 6 and the outer cylinder 7 of the control drum 5 described above are cylinders having the same dimensions up to both ends. However, it is not always necessary to have such cylinders. For example, like the outer cylinder shown in FIG. However, the inner cylinder only needs to have a shape corresponding to that, and furthermore, it may be a truncated cone shape like the outer cylinder shown in FIG. .
[0017]
In the above description, the outer cylinder is described as an integral cylinder, but it may be divided into two parts in the axial direction (a structure in which the divided parts are combined as shown in FIG. 4). The part is firmly locked, but the locked state is, for example, the connecting part on one side is pivotably connected by a hinge, and the other side is locked and connected to each other, and both connecting parts are locked and connected. As a structure to do. With such a split structure, since the outer cylinder is opened, it is easy to attach the wire rope to the control drum 5, and the inner cylinder is shaped like a drum with a narrowed center. However, an outer cylinder can be attached.
[0018]
Each of the above explanations is based on the case where the wire rope is wound around the winch of the crane. However, the description is not necessarily limited to the winch of the crane, and the wire rope is unwound from the drum around which it is wound and wound around another winch. In any case, it is effective as described above.
[0019]
【The invention's effect】
According to the present invention described in detail above, a spiral groove is formed on the inner surface, and the inner cylinder is fitted to an outer cylinder provided with a supply port and a discharge port for the wire rope, and the inner cylinder is rotatably supported and braked. By connecting to the device and fixing the outer cylinder to the apparatus main body, the wire rope supplied from the supply port and wound around the inner cylinder has contact friction with the outer peripheral surface of the inner cylinder whose rotation is controlled and the spiral groove. A large tensile force can be obtained by the contact friction of both the contact friction with the wire, and this has the effect of removing the initial elongation of the wire rope and winding it tightly in a tightly packed state on the winch.
[0020]
By being able to be wound tightly around the winch in this way, even if a large tension is applied to the wire rope fed out from the winch, the wire rope does not break into the layer stacked on the winch.
In addition, since the pulling force on the winding side is not transmitted to the wooden drum around which the wire rope is wound, the wire rope is interrupted between the wire ropes wound in a multi-layered state, resulting in a turbulent winding state or fixing. This has the effect of eliminating the state.
