No. 43649. In this known example, a brake shoe is built in a drum, and a lug of the drum is held to a part of the cage by a stopper plate. In an emergency, the shoe is pushed into the inner surface of the drum at a stroke to stop the descent of the cage.
It is a so-called "early" stop device. Since the descending speed of the elevator is 45 m / min or less, legal regulations stipulate that the speed may be early. ing.

擦によるブレーキ作用で、次第ぎきを可能とさせる。Conventionally, a lug of a drum is locked at one point to a detent plate, but a bolt hole of the lug is formed in an arc-shaped long hole.
A strong pressure is applied to the retaining bolt by a disc spring, and the retaining bolt is retained at one end of the elongated hole. When the shoe bites into the drum, the drum rotates against the strong friction caused by the disc spring, and stops when the retaining bolt reaches the long hole or the other end. The braking action by the friction during this time makes it possible to gradually move.

Although not shown, a guide rail and a pin rack are provided on the wall surface, and the pinion 2 meshes with the pin rack to raise and lower the elevator. The drum 3 is rotatably supported on the pinion shaft 1 and has an ear 3a fixed to the outer periphery thereof. The ear has an arc-shaped long hole 3b. The disk 4 is fixed to the pinion shaft 1 and the shoes 5
Is supported. The link 6 connects the head and tail of the mating shoe, and the shoe is normally separated from the inner surface of the drum by an attached spring (not shown). When the speed of the pinion shaft is abnormally increased, the shoe bites into the inner surface of the drum and stops the rotation of the pinion shaft immediately if the drum is prevented from rotating around the cage by a locking plate described below.

A coned disk spring is arranged on the outer surface, and the ear 3a is clamped between the two.

間に停止時の衝撃を緩和する。As shown in FIG. 1, the bolt 10 is always firmly fastened to the retaining plate 7 at one end of the arc-shaped long hole 3b. When the cage slowly descends, the pinion shaft 1 rotates counterclockwise in FIG. 1, but the shoe and the drum do not engage because the rotation is slow.
When the shoe starts to spin suddenly in an accident, the shoe cuts into the drum and tries to stop the descent at once. At this time, a strong torque acts on the drum to rotate the drum against the braking action of the bolt 10, and the rotation is stopped when the bolt 10 reaches the range of the arc-shaped long hole or reaches the other end. During this time, the impact at the time of stopping is reduced.
