Accordingly, the governor rope 100 can be moved by the governor sheave 12 which rotates as the elevator 2 moves.

The governor rope 100 may be suspended from the pulley 200 and cause rotation and movement of the pulley 200 as the elevator 2 moves. Here, the pulley 200 moves up and down with the lever 500 connected to one of the pair of guide rails 600.

FIG. 3 is a front view and a side view showing an elevator governor rope tension device according to the present invention, and FIG. 4 is a side view illustrating the movement of the lever in accordance with the movement of the base frame in the elevator governor rope tension device according to the present invention. to be.

3 and 4, an elevator governor rope tensioning device is connected to a pulley 200 suspended from a governor rope 100 which moves according to the movement of an elevator. In this elevator governor rope tension device, A base frame (300) rotatably coupled to a central portion of the elevator (200) and including a plate slit (310) passing through a side thereof in a direction perpendicular to the movement of the elevator; A center weight 400 fixed to the center shaft of the other end of the base frame 300 so as to maintain a predetermined tension on the governor rope 100; And a lever 500 accommodated in the plate slit 310 and moving up and down in a guide rail 600 formed on one side of the pulley 200 according to the movement of the pulley 200.

The governor rope 100 may be connected to the governor to move together with the elevator, and may be wound on the pulley 200. The pulley 200 is formed around the U-shaped groove and rotates clockwise or counterclockwise according to the movement (i.e., winding and unwinding) of the governor rope 100 to move up and down like a moving drum . The pulley 200 may further include a safety switch for measuring elongation of the governor rope 100.

The pulley 200 can be rotated at the same speed as the elevator connected to the governor rope 100 by the governor rope 100 to measure the moving speed of the elevator. That is, the pulley 200 can determine whether the elevator is overspeed based on the moving speed of the elevator.

The base frame 300 is a substantially plate-shaped member having a radius equal to or greater than the diameter of the pulley 200, and the rotation axis of the pulley 200 is connected to the base frame 300.

The central portion of the base frame 300 is rotatably engaged with the pulley 200 so that the pulley 200 can freely move according to the movement of the governor rope 100. Specifically, the base frame 300 is connected to the rotation shaft of the pulley 200 by a member such as a shaft, a bearing, and a nut so that the pulley 200 is rotated in a state fixed to the base frame 300 . The governor rope 100 is wound on the pulley 200 so that the pulley 200 and the base frame 300 can move up and down like a moving drum as the governor rope 100 moves.

A center weight 400 having a predetermined weight is connected to the lower end of the base frame 300. The lower end of the base frame 300 may be fixedly connected to the center weight 400 through bolts and nuts and may be integrated with the center weight 400.

As shown in FIG. 3B, the base frame 300 is formed with at least one guide plate, and a plate slit 310 is formed in the guide plate. The guide plate may correspond to a plate member attached to the base frame 300 and the plate slit 310 may correspond to a hole penetrating the side surface of the guide plate in a direction perpendicular to the movement of the elevator.

The plate slit 310 is formed on at least one of the left end and the right end of the base frame 300 so as to have a specific length in the lower end direction from the upper end of the guide plate 300, So that it can move up and down in a seated state. Here, the specific length may be longer than the length of the lever 500, and the plate slit 310 may be formed at both the left end and the right end of the base frame 300, Can be formed in one.

More specifically, the plate slit 310 is longer than the lever 500 to allow the lever 500 to be seated. The plate slit 310 is longer than the lever 500 so that the lever 500 Can be moved up and down. For example, the vertical width of the plate slit 310 may be extended from a center axis of the pulley 200 to a position where the plate slit 310 is fixedly connected to the center weight 400.

The base frame 300 may further include a stopper 320 disposed on the base frame 300 for forcibly stopping the rotation of the pulley 200 according to the moving speed of the elevator. The stopper 320 measures the moving speed of the elevator based on the rotational speed of the pulley 200 in the speed measuring sensor connected to the pulley 200 to determine whether the elevator is overspeed, Can be forcibly stopped. That is, the stopper 320 may stop the rotation of the pulley 200 when the elevator exceeds a predetermined speed.

Although the present invention has been described in connection with the case where the base frame 300 has a rectangular shape, the present invention is not limited thereto. The base plate 300 may be connected to the pulley 200 and the center weight 400, Any shape can be employed as long as the shape can be included.

The center weight 400 has a constant weight and is connected to the other end of the base frame 300 to maintain a constant tension on the governor rope 100. For example, the weight 400 may have a weight of 25 to 35 kg.

The lever 500 has one end connected to the base frame 300 and the other end connected to the guide rail 600 to connect the base frame 300 and the guide rail 600 to each other. More specifically, one end of the lever 500 is inserted into the plate slit 310 of the guide plate of the base frame 300, and the other end thereof is fixed to the guide rail 600. The pulleys 200 and the fixed base frame 300 are moved up and down according to the rotation of the pulley 200 and the lever 500 having one end inserted into the plate slit 310 of the base frame 300 So that the pulley 200 can be fixed to the guide rail 600 and move stably without shaking.

The lever 500 moves up and down in the plate slit 310 according to the rotation of the pulley 200. 3, when the base frame 300 moves upward, the lever 500 spans the lower end of the plate slit 310 and moves upward (a), and the base frame 300 (B) can be moved downwardly over the upper end of the plate slit 310 when it moves downward.

The lever 500 may be guided by the lever guide 700 connected to the guide plate so as to be moved up and down by the plate slit 310 without being detached from the plate slit 310.

The lever guide 700 prevents the one end of the lever 500 from separating from the plate slit 310 and is connected to the guide plate to move up and down.

More specifically, the lever guide 700 is connected to both sides of the guide plate to prevent the lever 500 from being separated from the plate slit 310, and the lever 500 is balanced (i.e., horizontal) The guide rail 600 can be guided to move up and down along the guide rail 600.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but rather are not intended to limit the scope of the technical idea of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
