【発明の詳細な説明】 本発明はキヤプスタンの改良に係る。[Detailed description of the invention] The present invention relates to improvements in capstans.
キヤプスタンは、軸方向中央を最小径とした彎
曲周面をそなえており、巻取るべきワイヤロープ

る。 The capstan has a curved circumferential surface with the smallest diameter at the center in the axial direction, and the wire rope to be wound is wound around the circumferential surface several times, and the wire rope is wound by rotation of the capstan.

じるため、振動、騒音を生じる場合があつた。 During winding, the wire rope sequentially moves from one side in the axial direction of the capstan, which is the wire lead-in side, to the other side, which is the pull-out side, but during this time, the wire rope becomes twisted due to friction between the capstan and the wire rope. Sometimes. Furthermore, if a large diameter portion of the wire rope, such as a connector, enters the capstan, it may rub against the adjacent windings of the wire rope and damage them. Furthermore, when the tension on the wire rope is large, the windings of adjacent wire ropes mesh with each other, making it impossible for the capstan to slide in the axial direction, causing the windings of the wire rope to overlap the large-diameter end of the capstan shaft. This caused vibrations and noise to occur as the vehicle gradually ran over the surface of the vehicle, and when it reached a certain point, it slipped off.

ヤプスタンを提供する。 The present invention has been made based on the above circumstances, and there is no risk of twisting the wire rope, and even if a large diameter part such as a connector enters the wire rope, the wire rope will not be damaged, and the wire rope will not be damaged. To provide a capstan capable of quiet operation even when the tension is large.

In the figure, a motor 2 is installed on the top surface of the base 1, and a capstan base 3 is installed on the side of the base 1.
is driven by the motor 2 via a reduction gear (not shown) installed in the base 1.

引張ばね７，７によつて連結されている。 A pulley 4 located directly below the capstan base 3 and having an axis 4a parallel to the capstan base 3 is engaged with elongated holes 6a, 6a of bearings 6, 6 on a bracket 5 projecting laterally from the base 1. is set up. Further, both ends of the shaft 4a and the upper surface of the bracket 5 are connected by tension springs 7, 7.

ておく。 Further, between the capstan base 3 and the pulley 4, there is an endless belt 10, which is constructed by connecting two wire ropes 8 in parallel to each other, and connecting both ends of the belt with a connector 9 so that they can be freely connected and separated. It's being passed around. That is, for example, the capstan base 3 is wound six times, and the pulley 4 is wound half a turn.

基く振動、騒音等を発生することはない。 In the capstan of the present invention having the above configuration, the wire rope W to be taken up is the endless belt 1
The wire rope is wound around the capstan base 3 by engaging the trough formed between the two interconnected wire ropes forming the wire rope. Since the endless belt 10 is tensioned by the tension spring 7,
It moves as the capstan base 3 rotates. As a result, the capstan base 3 is engaged with the valley.
The wire rope W wound around will also be taken off. Therefore, since the wire rope W does not slip against the capstan base 3, the wire rope is not twisted. Further, since adjacent windings do not come into close contact as in the conventional case, even if a large diameter portion such as a connector enters the wire rope, there is no risk of damaging the wire rope of the adjacent windings. moreover,
As mentioned above, since adjacent turns are not in close contact,
Even when the tension acting on the wire rope W is large, adjacent windings do not mesh with each other, and vibrations, noise, etc. due to this do not occur.
なお、エンドレスベルト１０はコネクタ９によ
り切離し得るようにしてあるので、ワイヤロープ
Ｗの中間における係合、離脱を容易になし得る。 In addition, since the endless belt 10 can be separated by the connector 9, the wire rope W can be easily engaged and disengaged in the middle.
