とするものである。 This invention solves the above-mentioned drawbacks and aims to provide a hoisting drum type elevator device that can prevent accidents due to overwinding of the hoisting machine through stable operation.
以下、第１〜第４図によつてこの考案の一実施
例を説明する。 An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

源である。 In the figure, 1 is the hoistway of the elevator, 2 is the machine room installed at the top of this, 3 is the hoisting machine installed in the machine room 2, 3a is the winding drum of this, and 4 is the machine room 2.
5 is a fixed body provided in the lower surface of the floor of the machine room 2 and has a hole 5a similar to the through hole 4; 6 is a fixed body whose one end is connected to the winding drum 3a; 3a and is wound around the through holes 4 and 5.
The main rope is inserted through a, 7 is a cage connected to the hanging end of the main rope, 8 is an L-shaped metal fitting arranged opposite to each other, and a bolt 8a inserted through the main rope and a nut 8b screwed into this are attached. Therefore, the engaging element 9 is clamped by the main rope 6 and placed near the car 7, and 9 is a control device consisting of an overload relay, etc., which operates when an overload is applied to the hoisting machine 3, which will be described in detail later. , - is the power supply.

７内の乗客が感じる衝撃による不快感を少なくす
ることができる。 That is, the engager 8 is held on the main rope 6 by frictional force, and the car 7 is driven via the main rope 6 by the hoisting machine 3 being energized. and,
If overwinding occurs in the hoisting machine 3, the car 7 rises beyond a predetermined position, but at this time the engaging element 8 collides with the fixed body 5. As a result, the main rope 6 is wound up against the frictional holding force between the main rope 6 and the engaging element 8, and an overload is applied to the hoist 3. This overload causes the control device 9 to operate and deenergize the hoisting machine 3, thereby preventing accidents due to overwinding. Further, the collision when the engaging element 8 collides with the fixed body 5 is buffered by the friction between the engaging element 8 and the main rope 6. Therefore, when overwinding occurs, no dangerous impact load is applied to the main rope 6 and the hoisting machine 3, so the car 7 can be stopped safely. Further, it is possible to reduce the discomfort felt by the passengers in the car 7 due to the impact when overwinding occurs.

巻胴式エレベータ装置を実現するものである。 As explained above, this invention provides an engager that is held by friction on the main rope that suspends the car. An overload is applied to the hoist by the frictional holding force generated by the collision with the fixed body, and the hoist is controlled by a control device operated by this overload. As a result, the collision between the engaging element and the fixed body during over-winding is buffered by the friction between the main rope and the engaging element, allowing safe and highly reliable operation to prevent accidents due to over-winding. This is to realize a winding drum type elevator system that can be used.
