The problem that invention will solve
, in recent years along with building is towards high stratification future development, the elevator of Long travel constantly increases.In the elevator of above-mentioned Long travel, due to the length of the speed controller rope 29 shown in Figure 10, therefore the force of inertia of speed controller rope 29 increases.Figure 12 represents the force of inertia F of speed controller rope 29.Following formula (1) and following formula (2) represent the relation between the force of inertia F of speed controller rope and the length L of speed controller rope.
F＝M×α …(1)
M＝m×L …(2)
(in formula, M: the weight of speed controller rope
α: the acceleration/accel of speed controller rope
M: the weight under the per unit length of speed controller rope)
As shown in above formula (1), the force of inertia F of speed controller rope and the weight M of speed controller rope is proportional, and as shown in above formula (2), the weight M of speed controller rope and the length L of speed controller rope is proportional, therefore, along with the length of speed controller rope, the increase that the force of inertia of speed controller rope 29 is also proportional.When the force of inertia of speed controller rope 29 becomes large, when the emergency braking making lift car 25 emergent stopping is carried out in the drg action by the winch 22 shown in Figure 10, the power upwards mentioning governor tension pulley block 31 becomes large, and the amount of takeofing of governor tension pulley block 31 may be caused to increase.

In addition, when using the ratchet device combined by ratchet slot and the ratchet pawl that engages with this ratchet slot, if the rigidity of ratchet slot part is weak, then when governor tension pulley block 31 is for takeofing more greatly, ratchet slot may be caused to deform or damage, thus takeofing of governor tension pulley block 31 cannot be limited.Especially in the occasion of the elevator of Long travel, because the force of inertia of speed controller rope 29 increases, the power therefore acted on ratchet slot also increases, and ratchet slot may be caused to deform or damage, thus cannot limit takeofing of governor tension pulley block 31.
In addition, along with the time dependent of speed controller rope 29 is aging, be bound to the situation occurring that speed controller rope 29 extends, and therefore, must guarantee the movable range of governor tension pulley block 31 movement downward.Especially, in the elevator of Long travel, because the length of used speed controller rope 29 increases, therefore, the elongation caused because time dependent is aging also can increase.

Detailed description of the invention
Below, with reference to accompanying drawing, embodiments of the present invention are described.
Fig. 1 represents the elevator of the governor be provided with involved by embodiments of the present invention, and the part general with Figure 10 marks identical Reference numeral.In the Machine Room 20 on elevator top, on the rope sheave that main hoist cable 21 is wound on winch 22 and pulley 23.One end of main hoist cable 21 is connected with the top of lift car 25 in hoist trunk 24, and the other end of main hoist cable 21 is connected with the top of counterbalanced weight 26 in hoist trunk 24.The bottom of lift car 25 is connected by the counterbalanced weight rope 28 be wound on the counterweight block 27 being located at hoist trunk 24 bottom with the bottom of counterbalanced weight 26.Winch 22 in Machine Room 20 is driven main hoist cable 21 by friction, makes lift car 25 be elevated in hoist trunk 24 thus.
Lift car 25 is also connected with speed controller rope 29.Speed controller rope 29 is wound on the governor main body 30 that is positioned at Machine Room 20 and is arranged on the governor tension pulley block of hoist trunk 24 bottom.Governor main body 30 detects the speed of lift car 25 according to the rate of circulation of speed controller rope 29, detect overrun time, making not shown emergency braking apparatus action by clamping speed controller rope 29, playing effect lift car 25 being carried out to emergency braking thus.Governor tension pulley block 1 plays the effect of setting up speed controller rope 29 in the mode of tensioning.
Fig. 2 represents the structure of the governor tension pulley block 1 shown in Fig. 1.Governor tension pulley block 1 is made up of pulley main body 2 and flat pulley bearing body 3, and this pulley main body 2 reels for speed controller rope 29, and pulley main body 2 supports as rotating by flat pulley bearing body 3.It should be noted that, the side end 3a of pulley bearing body 3 has plane (side).In addition, pulley bearing body 3 is guided from both sides by two the tension pulley block guiding pieces 4 vertically extended.
At the both side ends 3a of pulley bearing body 3, be vertically formed with multiple ratchet slot 5.Each ratchet slot 5 have the inclined upward of the side end 3a towards pulley bearing body 3 sloping portion 5a and in the below of sloping portion 5a along the horizontal component 5b that the direction that the side end 3a with pulley bearing body 3 is vertical extends.In addition, between sloping portion 5a with horizontal component 5b, be formed with the vertical component 5c extended along the direction that the side end 3a with pulley bearing body 3 is parallel.In addition, between each ratchet slot 5, multiple rigid element 6 is formed with.Rigid element 6 is formed as the plane of the side end 3a comprising pulley bearing body 3.As mentioned above, by rigid element 6 is formed as the plane comprising side end 3a, the volume of rigid element 6 can be increased to a certain extent, the rigidity of ratchet slot 5 can be strengthened thus.
Ratchet pawl 7 can be installed on each tension roller guiding piece 4 movably.Ratchet pawl 7 is supported by the columned pin 10 running through ratchet pawl 7 bottom, can rotate along the circumferencial direction of pin 10 and move.The claw of ratchet pawl 7 as shown in Figure 2, when to observe towards the state of pulley bearing body 3 side for benchmark, there is top snap portions and bottom snap portions, top snap portions has the sloping portion 7a that the front end towards claw tilts, bottom snap portions is arranged on the below of top snap portions, has the horizontal component 7b extended along horizontal direction.In addition, ratchet pawl 7 has and is connected and the base portion extended along the direction vertical with claw with claw, is formed with the through hole that supply and marketing 10 is inserted in the lower end of base portion.
In addition, ratchet pawl 7 is provided with a kind of helical torsional spring 11 as biasing member.This helical torsional spring 11, for pushing ratchet pawl 7, makes ratchet pawl 7 rotate (ratchet pawl 7 on the left of Fig. 2 rotates toward the clockwise direction, and the ratchet pawl 7 on the right side of Fig. 2 counterclockwise rotates) towards pulley bearing body 3 side.
Made ratchet pawl 7 rotate towards pulley bearing body 3 side as described above by pushing ratchet pawl 7, as shown in Figure 2, abut in the mode that the horizontal component 7b of ratchet pawl 7 is opposite with the horizontal component 5b of ratchet slot 5, ratchet pawl 7 engages with ratchet slot 5.It should be noted that, in the present embodiment, ratchet pawl 7 engages with the ratchet slot 5 of the most subordinate of pulley bearing body 3.
Upper end as a kind of extension spring 8 of elastic component is connected with the bottom of pulley bearing body 3.In addition, the rod member 9 extended along horizontal direction is fixed near the bottom of two tension roller guiding pieces 4, and the lower end of extension spring 8 is connected with this rod member 9.It should be noted that, rod member 9 is made up of the metal that rigidity is large.
The governor of elevator involved according to the present embodiment, use the ratchet device having and be formed in ratchet slot 5 on pulley bearing body 3 and ratchet pawl 7, make the horizontal component 7b of the lower surface of ratchet pawl 7 abut with the horizontal component 5b of the lower surface of ratchet slot 5 and engage.Thus, when effect has the power up mentioned by governor tension roller 1, by making ratchet pawl 7 engage with ratchet slot 5, can prevent governor tension roller 1 from takeofing.
In addition, by being provided with rigid element 6 between each adjacent ratchet slot 5, thus the front end of toothed portion between ratchet slot 5 and ratchet slot 5 is thicker, and the rigidity of ratchet slot 5 is improved.Therefore, in the elevator of Long travel, even if will act on more energetically on ratchet slot 5 when governor tension roller 1 is for takeofing more greatly, the tooth between ratchet slot 5 and ratchet slot 5 also can not deform and breakage, reliably can limit governor tension roller 1 and takeoff.As mentioned above, by takeofing of restriction governor tension roller 1, the tension force acted on speed controller rope 29 can be maintained, the lax of speed controller rope 29 or vibration can be reduced, even if governor main body 30 also can be made when emergency braking normally to work.
On the other hand, the action of ratchet device when Fig. 3 represents that speed controller rope 29 extends because time dependent is aging.State when Fig. 3 A represents that ratchet pawl 7 engages with the ratchet slot 5 of pulley bearing body 3.In this condition, when speed controller rope 29 extends because time dependent is aging, pulley bearing body 3 moves downward, as represented successively in Fig. 3 B and Fig. 3 C, under the effect of governor with the deadweight of tension roller 1, the sloping portion 7a of ratchet pawl 7, along the sloping portion 5a of the upper surface of ratchet slot 5, overcomes the thrust pressure of biasing member, rotates towards the direction contrary with press direction.After this, as shown in Figure 3 D, ratchet pawl 7 departs from ratchet slot 5, the state that the front end becoming claw contacts with the rigid element 6 be arranged between this ratchet slot 5 and ratchet slot 5 of upper class.That is, the front end of claw abuts with the plane of the side end 3a of pulley bearing body 3.After this, as shown in FIGURE 3 E, along with the movement of pulley bearing body 3, the front end of claw arrives the ratchet slot 5 of upper class, engages under the effect of the thrust pressure of the helical torsional spring 11 shown in Fig. 2 with this ratchet slot 5 identically with the state shown in Fig. 3 A.
As mentioned above, when speed controller rope 29 extends because time dependent is aging, under the effect of governor with the deadweight of tension pulley block 1, the sloping portion 7a of the upper surface of ratchet pawl 7 moves along the sloping portion 5a of the upper surface of ratchet slot 5, and ratchet pawl 7 is rotated towards the direction contrary with press direction.After this, under the effect of the thrust pressure of helical torsional spring 11, ratchet pawl 7 engages with the ratchet slot 5 of upper class, and thus, governor tension pulley block 1 can extend along with speed controller rope 29 and move downward.
In addition, because ratchet slot 5 has vertical component 5c between sloping portion 5a and horizontal component 5b, therefore, it is possible to the horizontal component 5b of the horizontal component 7b and ratchet slot 5 that form only ratchet pawl 7 abuts and the state that sloping portion 7a does not abut with ratchet slot 5.That is, under the state that can engage with ratchet slot 5 at ratchet pawl 7, between ratchet pawl 7 and ratchet slot 5, space is formed.Thereby, it is possible to make ratchet pawl 7 deviate from from ratchet pawl 5 easily, thus governor tension pulley block 1 can be reliably made to move downward.
In addition, vertical component 5c is set, the time of the fastening state of the ratchet pawl 7 shown in Fig. 3 B and Fig. 3 C and ratchet slot 5 can be extended.Thus, when governor tension pulley block 1 takeoffs more greatly, the state that the horizontal component 5b of the horizontal component 7b and the lower surface of ratchet slot 5 that can return the ratchet pawl 7 shown in Fig. 3 A abuts.Thus, when being provided with rigid element 6, also can keep reliably limiting the state that governor tension pulley block 1 takeoffs for a long time.
At this, as shown in Figure 3 D, during being in the front end of ratchet pawl 7 state abutted with rigid element 6, governor tension pulley block 1 cannot being limited by ratchet device and takeoff.Therefore, in the present embodiment, the extension spring 8 coupled together in the bottom of pulley bearing body 3 and rod member 9 is set, when governor tension pulley block 1 is for takeofing more greatly, the recuperability of extension spring 8 can be relied on to be pulled downward by pulley bearing body 3, governor tension pulley block 1 can be limited thus and takeoff.
In addition, because extension spring 8 is connected with the rod member 9 be arranged on tension roller guiding piece 4, therefore when lift car 25 travels usually, can by the circulation of the rotation of pulley main body 2 and speed controller rope 29 and the vibration etc. produced discharge to tension roller guiding piece 4, rocking of lift car 25 can be alleviated thus.
Above, embodiments of the present invention are illustrated.Such as, but the present invention is not by the restriction of above-mentioned embodiment, and cited by following first variation to the 4th variation, the present invention can implement various distortion in the scope not departing from the purport of the present invention described in claims.
First variation
In the above-described embodiment, as shown in Figure 3 D, show during ratchet pawl 7 is in the state abutted with rigid element 6, limit by the extension spring 8 coupled together in the bottom of pulley bearing body 3 and rod member 9 example that governor tension pulley block 1 takeoffs., along with the stroke of elevator is elongated, when the force of inertia of speed controller rope 29 becomes large, in order to improve recuperability, need to use large diameter extension spring 8.As shown in the example of Fig. 4 B, when using large diameter extension spring 8, the width of extension spring 8 becomes larger than the width of governor tension pulley block 1, and the width along with this extension spring 8 becomes large, needs to guarantee corresponding space.
Therefore, in order to prevent above-mentioned space from increasing, as shown in the example of Fig. 4 A and Fig. 5, also can disperse recuperability by using many extension springs 15 ~ 17, the diameter of spring can be suppressed thus to become large.That is, can be set to utilize many diameters to connect the bottom of pulley bearing body 3 and the rod member 9 of tension pulley block guiding piece 4 side at the extension spring of governor within the width of tension pulley block 1, suppress takeofing of governor tension pulley block 1 with this.
Second variation
In the above-described embodiment, the example being connected the bottom of pulley bearing body 3 and the rod member 9 of tension pulley block guiding piece 4 side by extension spring 8 is shown.But, as shown in Figure 6, as the elastic component with recuperability beyond extension spring, also can adopt the rubber 18 of strand, connect the bottom of pulley bearing body 3 and the rod member 9 of tension pulley block guiding piece 4 side by the rubber 18 of strand.It should be noted that, also can use multiple rubber 18.
3rd variation
In the above-described embodiment, the example be connected with the mounting rod 9 be fixedly mounted on tension pulley block guiding piece 4 lower end of extension spring 8 is shown.In this example, along with speed controller rope 29 extends because generation time dependent is aging, governor tension pulley block 1 moves downward, and now, as shown in Figure 7, extension spring 8 is pressed downwardly and shrinks.But, be retracted to a certain degree at extension spring 8, as shown in Figure 3 D, under the state that the front end of ratchet pawl 7 abuts with rigid element 6, when governor tension pulley block 1 is for takeofing more greatly, until the recuperability of extension spring 8 plays a role, the required time is long, is sometimes difficult to suppress takeofing of governor tension pulley block 1.
For this reason, as when governor tension pulley block 1 moves downward for regulating the mechanism of extension spring 8 length in vertical direction, as shown in Figure 8, multiple screw hole 19 for removably installation member 9 can be set on tension pulley block guiding piece 4.Thus, first rod member 9 is arranged in the screw hole 19 of the top of tension pulley block guiding piece 4, when maintenance examination etc., if find the benchmark of the contraction of extension spring 8 beyond regulation, rod member 9 is moved to the screw hole 19 of below, extension spring 8 can be made thus to return to the original length.Thereby, it is possible to reliably limit takeofing of governor tension roller 1.
4th variation
In the above-described embodiment, the example shape of the horizontal component 7b of ratchet pawl 7 being formed as even shape is shown.But, as shown in Figure 9, also the shape of horizontal component 7b can be formed as the shape with minute asperities, or also slip prevention part can be set by pasting anti-skidding component at horizontal component 7b.As mentioned above, by increasing the friction coefficient of horizontal component 7b of ratchet pawl 7, under making the state abutted against at horizontal component 7b and the horizontal component 5b of ratchet slot 5, ratchet pawl 7 is not easy slip relative to ratchet slot 5.Thereby, it is possible to suppress takeofing of governor tension roller 1 more reliably.
