Problems solved by technology

[0009] However, in the project of installing the anti-vibration of the speed governor rope, the installation position of the anti-vibration increases in proportion to the length of the lifting stroke.
[0010] Also, since the work is at a high place, the work of installing the U-bolt to the bracket so as to surround the governor rope, inserting the nut into the U-bolt, and tightening while screwing in must be done carefully while ensuring safety.
Therefore, if there are many places where the governor ropes are installed for vibration isolation, it will take a long time to install all the vibration isolation components.

no. 1 Embodiment approach

[0027] figure 1 It is a figure which shows the outline|summary of the elevator to which the vibration-proof device of the governor rope based on embodiment of this invention was applied.

[0028] in the figure 1 Among them, reference numeral 10 denotes a hoistway of an elevator, and 14 denotes a car. The car 14 is suspended by a main rope 11 wound around a main sheave 12 of the hoisting machine. The car 14 moves up and down in the hoistway 10 while being guided by car guide rails 13 provided in the hoistway 10 .

[0029] A governor device (governor) 16 is provided in the machine room. This speed governor device 16 is equipped with a speed governor sheave 15, and is provided with a limit switch that cuts off the power supply of the traction machine when the moving speed of the car 14 exceeds the set first overspeed, or, if the car 14 If the moving speed exceeds the set second overspeed, the rope clamping mechanism of the governor rope 17 is held.

no. 2 Embodiment approach

[0049] Second, refer to Figure 5 , Figure 6 A second embodiment of the present invention will be described. Additionally, for figure 2 Components that are the same as those in the first embodiment are denoted by the same reference numerals and detailed description thereof will be omitted.

[0050] In this second embodiment, L-shaped grooves 40 and 41 are formed in the bracket 20 . The L-shaped grooves 40 and 41 are grooves that extend vertically and then bend at right angles (horizontally) with the upper edge of the bracket 20 as the groove entrance. The distance between the L-shaped grooves 40 and 41 substantially corresponds to the distance between both ends of the U-shaped bolt 32 . The speed governor rope 17 is located in the middle of the above-mentioned L-shaped grooves 40 , 41 .

[0051] According to the second embodiment configured as described above, the U-shaped bolt 32 and the lateral protector 22 can be attached to the bracket 20 as follows.

no. 3 Embodiment approach

[0057] Second, refer to Figure 7 , Figure 8 A third embodiment of the present invention will be described. Additionally, for figure 2 Components that are the same as those in the first embodiment are denoted by the same reference numerals and detailed description thereof will be omitted.

[0058] This third embodiment is an embodiment in which vertical grooves 42 and grooves 43 for temporarily attaching U-shaped bolts 32 are formed in the bracket 20 . One end of the U-shaped bolt 32 is engaged with the groove 43, and the U-shaped bolt 32 is temporarily attached so as to be rotatable.

[0059] The vertical groove 42 is a groove cut downward from the upper edge of the bracket 20 . The distance between the vertical groove 42 and the groove 43 substantially corresponds to the distance between both ends of the U-shaped bolt 32 .

[0060] According to the third embodiment configured as described above, the U-shaped bolt 32 and the lateral protector 22 can be attached to the ...

Abstract

To efficiently install a vibration stop device of a governor rope satisfying a latest earthquake resistance reference to a hoistway.A vibration stop device of a governor rope according to an embodiment of the invention comprises: a bracket 20 supported to a car guide rail 13 for guiding lifting up and down of a car 14; and an U-shaped bolt 32 which is coupled to the bracket 20 with nuts 33, 34 to surround a governor rope 17. The bracket 20 has a groove 30 to which the U-shaped bolt 32 to which nuts 33, 34 are attached is attached.

Description

technical field [0001] Embodiments of the present invention relate to an anti-vibration device of a governor rope and an installation method of the anti-vibration device. Background technique [0002] The elevator is provided with a governor device (governor) that operates when the moving speed of the car exceeds a predetermined value to automatically stop the car. A governor rope running in the same direction and at the same speed as the raising and lowering direction of the car is wound around a governor sheave of the governor device. The governor device detects that the moving speed of the car exceeds the set acceleration based on the rotation of the governor sheave, and makes the car come to an emergency stop. [0003] When an earthquake occurs, especially when a long-period earthquake occurs, the governor rope may vibrate greatly due to resonance. In the worst case, the governor rope may be caught in equipment or structures installed in the hoistway, and the governor ...
