Definitions
- the present invention relates to an elevator speed governor for detecting an overspeed of a car or a counterweight and operating an emergency stop device.
- an elevator speed governor having a pulley around which a speed governor rope is looped and a rope holding mechanism for holding a speed governor rope being supported by a stand.
- the rope holding mechanism is disposed below the pulley.
- a ratchet rotating coaxially with the pulley is also supported by the stand.
- the pulley is provided with a pawl that is engaged with the ratchet when the rotational speed of the pulley has reached a preset overspeed. The ratchet is rotated together with the pulley through engagement of the pawl with the ratchet.
- a hook member is coupled to the rope holding mechanism.
- the hook member In a normal state, the hook member is engaged with an engaging projection fixed to the stand.
- a lateral surface of the ratchet is provided with a disengaging projection for disengaging the hook member from the engaging projection.
- the hook member is pressed by the disengaging projection, which is moved as the ratchet rotates, and then is disengaged from the engaging projection.
- the rope holding mechanism is actuated through disengagement of the hook member from the engaging projection.
- a plurality of protruding portions for mounting the pulley, the ratchet, the rope holding mechanism, and the engaging projection are formed on the stand.
- Patent Document 1 JP 08-119555 A
- the disengaging projection simply extends from the lateral surface of the ratchet. Therefore, the ratchet and the hook member may be elastically deformed when the hook member is disengaged from the engaging projection, in the case where the ratchet is slowly rotated during, for example, an actuation checking test of the speed governor. In this case, the hook member escapes from the engaging projection. As a result, there is caused a problem in that the speed governor does not operate reliably.
- the stand assumes a complicated shape in order to support the pulley and the rope holding mechanism. In some cases, therefore, the stand is made of castings, section steel, or the like. As a result, the stand is increased in size to the extent of hindering the weight saving of the speed governor.
- the present invention has been made to solve the problems as described above. It is an object of the present invention to obtain an elevator speed governor which can be actuatedmore reliably.
- An elevator speed governor includes: a base installed within a hoistway; a pulley rotatably supported by the base and having a speed governor rope looped around the pulley, for rotating in accordance with a raising/lowering speed of a car; a ratchet provided with an engaging strip for actuation, and capable of rotating around a pulley shaft of the pulley; an engaging mechanism having a pawl, with which the pulley is provided turnably between an actuation position for being engaged with the ratchet and a release position for being disengaged from the ratchet, the pawl being turned from the release position to the actuation position, and rotating the ratchet in the same direction as the pulley when a rotational speed of the pulley has reached a set overspeed set in advance; an actuating lever which is brought into abutment on the engaging strip for actuation and displaced through movement of the engaging strip for actuation resulting from rotation of the ratchet; and

- the car 2 continues to be lowered.
- the actuating lever 9a is operated, and the emergency stop device 9 is actuated.
- Fig. 10 is an illustrative view showing a normal state of the speed governor 10 of Fig. 4.
- the actuating lever 38 is engaged with the engaging member 37, and the movable-side rope holding portion 35 is disposed at the open position.
- the upper return lever 43 has been turned radially inward because of the weight of the other end 43b, and the lower return lever 44 has been turned radially inward by being urged by the pulling spring 55.
- the pin 46 for the upper return lever abuts on the lower end of the long hole 53
- the mounting pin 41 for the actuating lever abuts on the upper end of the long hole 57.
- Fig. 11 is an illustrative view showing an operating state of the speed governor 10 of Fig. 10.
- the actuating lever 38 is disengaged from the engaging member 37, and the movable-side rope holding portion 32 is displaced from the open position to the binding position.
- the mounting pin 41 for the actuating lever is slid from the upper end to the lower end of the long hole 57 of the lower link 52.
- Figs. 12 to 14 are illustrative views for explaining the return operation of the speed governor 10 of Fig. 11.
- Fig. 12 is an illustrative view showing a state where the lower return lever 44 of Fig. 11 has been turned radially outward.
- Fig. 13 is an illustrative view showing a state where the lower link 52 of Fig. 12 has been displaced upward.
- Fig. 14 is an illustrative view showing a state where the upper return lever 43 of Fig. 13 has been turned radially outward.
- a reaction force acting against the pulling force applied to the wire 60 for remote control operation downward acts on a portion of the sheath mounting member 59 which is in contact with the wire 60 for remote control operation.
- the reaction force acting on the sheath mounting member 59 includes an upward component.
- the lower link 52 is thereby pulled upward while being slid along the long hole 56 with respect to the upper return lever 43.
- the pin 46 for the upper return lever is brought into abutment on the lower end of the long hole 56.
- the movable-side rope holding portion 35 is also displaced upward together with the lower link 52 (Fig. 13).
- the upper return lever 43 and the lower return lever 44 are turned radially outward, so one of the upper return lever 43 and the lower return lever 44 is brought into abutment on the return projection 45.
- the pawl 28 is thereby turned against the urging of the urging spring, and is returned from the actuation position at which the pawl 28 is engaged with the teeth of the ratchet 26 to the release position at which the pawl 28 is engaged with the trip lever 24.
- the pawl 28 can be returned from the actuation position to the release position when the return projection 45 exists on a turning path of one of the upper return lever 43 and the lower return lever 44.
- the return of the speed governor 10 is completed by displacing the pawl 28 to the release position and displacing the movable-side rope holding portion 35 to the open position in this manner.
- the ratchet 26 is provided with the engaging strip 27 for actuation for actuating the rope holding mechanism 31 by displacing the actuating lever 38, and the support plate 16 is provided with the groove portion 61 into which a part of the engaging strip 27 for actuation is inserted. Therefore, the actuating lever 38 can be prevented from escaping from a gap between the engaging strip 27 for actuation and the support plate 16, due to elastic deformation of the ratchet 26 and the support plate 16 which is caused when the engaging strip 27 for actuation is brought into abutment on the actuating lever 38. As a result, the actuating lever 38 can be displaced more reliably. Accordingly, the speed governor 10 can be actuated more reliably.
- One end 43a of the upper return lever 43 and one end 44a of the lower return lever 44, which are disposed around the pulley shaft 15 and curved so as to surround the pulley shaft 15, are turnably provided on the support plate 16.
- the pawl 28 is pressed upward by one of the upper return lever 43 and the lower return lever 44 that are turned in such a direction as to move away from the pulley shaft 15 (radially outward), and then is turned from the actuation position to the release position. Therefore, the range in which the pawl 28 is pressed upward to the release position by the upper return lever 43 and the lower return lever 44 is widened. As a result, the reliability of the return operation of the pawl 28 can be enhanced.
- the actuating lever 38 is interlocked with the upper return lever 43 and the lower return lever 44 by means of the link mechanism 50, and the wire 60 for remote control operation for displacing the link mechanism 50 is connected to the link mechanism 50. Therefore, the link mechanism 50 can be displaced, the pawl 28 can be displaced to the release position, and the movable-side rope holding portion 35 can be displaced to the open position simply by operating the wire 60 for remote control operation from, for example, a boarding area even if an operator does not enter the hoistway 1 to return the speed governor 10. Accordingly, the return operation following the trip operation of the speed governor 10 can be performed with ease.
- the base 14 has the pair of the support plates 16, 17 facing each other, and the speed governor sheave 13, the engaging mechanism 30, the actuating lever 38, and the rope holding mechanism 31 are disposed between the support plates 16 and 17. Therefore, the width dimension of the speed governor 10 can be reduced. Consequently, the speed governor 10 can be made compact and lightweight. Since the support plates 16, 17 can be made identical in shape, a plurality of superimposed metal plates can be simultaneously worked at the time of manufacturing the support plates 16, 17. As a result, the base 14 can be manufactured with ease.

- a portion of the support plate 16 which faces the engaging trip 27 for actuation is formed as a flat surface.
- Embodiment 2 is identical to Embodiment 1 in other constructional and operational details.
- the engaging strip 27 for actuation is provided with the engaging strip-side inclined portion 71 that is inclined in such a direction as to guide the actuating lever 38 toward the ratchet 26 side. Therefore, the actuating lever 38 can be prevented from escaping from a gap between the engaging strip 27 for actuation and the support plate 16 when the actuating lever 38 is brought into abutment on the engaging strip 27 for actuation. As a result, the trip operation of the speed governor 10 can be performed more reliably.
- Fig. 17 is a sectional view of an essential part of the speed governor 10 according to Embodiment 3 of the present invention.
- the actuating lever 38 may also be provided with an inclined portion. That is, while a portion of the engaging strip 27 for actuation which abuts on the actuating lever 38 is provided with the engaging strip-side inclined portion 71, a portion of the actuating lever 38 which abuts on the engaging strip 27 for actuation is provided with a lever-side inclined portion 72 that is substantially parallel to the engaging strip-side inclined portion 71.
- lever-side inclined portion 72 is inclined in such a direction as to guide the actuating lever 38 toward the ratchet 26 side through abutment on the engaging strip 27 for actuation.
- Embodiment 3 is identical to Embodiment 2 in other constructional and operational details.
- the portion of the actuating lever 38 which abuts on the engaging strip 27 for actuation is provided with the lever-side inclined portion 72 that is substantially parallel to the engaging strip-side inclined portion 71. Therefore, the trip operation of the speed governor 10 can be performed more reliably.
- the portion of the support plate 16 which faces the engaging strip 27 for actuation is formed as a flat surface in Embodiments 2 and 3, a groove portion into which the engaging strip 27 for actuation is inserted may be formed in the support plate 16 as is the case with Embodiment 1. If this construction is adopted, the trip operation of the speed governor 10 can be performed more reliably.
