All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment, as shown in fig. 1, the present application provides an elevator comprising a car (not shown) and a control cabinet (not shown) that transmits signals to and from the car via a cable 50. The elevator further includes a shaking prevention device 100 of the elevator trailing cable, and the shaking prevention device 100 of the elevator trailing cable is used to prevent the cable 50 connected between the car and the control cabinet from shaking.

In another embodiment, as shown in fig. 1 to 4, an anti-sloshing apparatus 100 for an elevator trailing cable includes a guide rail 20 and a cable trailing rack 10 moving along the guide rail 20, the cable trailing rack 10 having a passage through which a cable 50 passes, the guide rail 20 being a plurality of and surrounding the passage; the cable follower 10 has a descending state driven by its own weight and an ascending state pulled by the cable 50.

It will be appreciated that the guide rails 20 are each mounted within a hoistway (not shown). When the cable 50 moves along with the car, the cable 50 pulls the cable traveling rack 10 to move on the guide rails 20, and the plurality of guide rails 20 are arranged around the channel, so that the cable pulling force applied to the cable traveling rack 10 is uniformly distributed on the plurality of guide rails 20, the cable traveling rack 10 and the guide rails 20 are prevented from being clamped with each other, and the cable traveling rack 10 can slide more smoothly along the guide rails 20. The plurality of guide rails 20 restrict the movement of the cable traveling frame 10, and can prevent the cable traveling frame 10 from deflecting in the horizontal direction, thereby reducing or preventing the cable 50 from shaking when moving along with the car.

Meanwhile, because the cable follower 10 is at the lowest end of the cable 50 due to the gravity of the cable follower 10, the cable 50 between the control cabinet and the cable follower 10 is completely arranged between the plurality of guide rails 20, and even if the cable 50 shakes, the cable 50 is blocked by the guide rails 20 to limit the shaking range of the cable 50.

In another embodiment, as shown in fig. 1 and 2, the cable 50 is a flat cable 50, two friction-reducing rollers 12 are rotatably mounted on the cable follower 10, the two friction-reducing rollers 12 are respectively disposed on two sides of the thickness of the cable 50, and the cable 50 pulls the cable follower 10 to ascend through one of the friction-reducing rollers 12.

It will be appreciated that the two friction reducing rollers 12 are parallel to each other and are spaced apart by a distance greater than the thickness of the cable 50 so that the cable 50 can slide relative to the cable follower 10. When the cable 50 pulls the cable traveling rack 10 to slide on the guide rail 20, the cable 50 can move relative to the cable traveling rack 10 through the antifriction rollers 12, and the antifriction rollers 12 can rotate along with the cable 50, so that the friction force between the cable 50 and the cable traveling rack 10 can be reduced, the friction contact between the cable 50 and the cable traveling rack 10 is avoided, and the possibility of scraping between the cable 50 and the cable traveling rack 10 is caused.

The surface of the antifriction roller 12 is made of a friction-resistant material with a low friction coefficient, such as plastic, so that the possibility of scraping between the antifriction roller 12 and the cable 50 can be further avoided.

Further, the antifriction roller 12 includes a fixed shaft (not shown) and a roller (not shown) sleeved outside the fixed shaft, two ends of the fixed shaft are respectively fixedly connected with the cable follower rack 10, and the roller can rotate relative to the fixed shaft.

In another embodiment, as shown in fig. 1 and 2, a plurality of guide sleeves 11 are installed on the cable follower rack 10, and each guide sleeve 11 is slidably sleeved on a corresponding one of the guide rails 20.

It can be understood that the guide sleeve 11 has a guide hole for the guide rail 20 to pass through, and the guide rail 20 and the guide sleeve 11 are fixed by interference fit or other means, so that the cable follower stand 10 can smoothly run along the guide rail 20 (i.e. in the vertical direction). Meanwhile, the guide sleeve 11 has a certain length, and when the guide rail 20 passes through the guide sleeve 11, the reserved gap between the guide sleeve 11 and the guide rail 20 can prevent the bracket from excessively inclining.

In another embodiment, as shown in fig. 1, 3 and 4, the anti-sway device 100 for elevator trailing cables further comprises two fixing frames, and the guide rail 20 is a flexible guide rail and is tightened between the two fixing frames.

It will be appreciated that both mounts are fixed within the hoistway, and specifically include a first mount 30a disposed at the top of the hoistway and a second mount 30b fixed at the bottom of the hoistway.

The guide rail 20 is a steel wire rope, and in the process that the guide rail 20 is installed on the two fixing frames, the two ends of the steel wire rope are respectively fixed on the two fixing frames, and the steel wire rope is tightened, so that the guide rail 20 for the cable traveling frame 10 to slide can be formed, and the requirement on the machining precision of the guide rail 20 can be reduced.

Wherein, two mounts pass through expansion bolts (or chemical anchor) respectively and reliably be connected with the well. The cable 50 between the car and the control cabinet moves along with the running of the car, and the length of the moving part of the cable 50 is equal to half of the running height of the car (namely, half of the height of the hoistway).

In another embodiment, as shown in fig. 1 and 3, the second fixing frame 30b is rotatably installed with rollers 31, the guide rails 20 are grouped in pairs, and the two guide rails 20 in the same group are connected together and wound around the rollers 31.

It can be understood that two guide rails 20 in the same group can be installed between the two fixing frames by only connecting the two guide rails 20 in the same group with the first fixing frame 30a, thereby reducing the installation steps of the guide rails 20. Meanwhile, the distance between the two guide rails 20 in the same group on the first fixing frame 30a is the diameter of the roller 31, that is, only the mounting positions of the two guide rails 20 on the first fixing frame 30a need to be positioned, and the requirement on the accuracy of the guide rails 20 mounted on the whole fixing frame is reduced.

The two sides of the roller 31 are fixed with a rotating shaft, the second fixing frame 30b is provided with a rotating groove matched with the rotating shaft, and the roller 31 is matched with the rotating groove through the rotating shaft, so that the roller 31 can be rotatably installed on the second fixing frame 30 b.

Further, the roller 31 is opened with an annular groove 33 engaged with the guide rail 20. When the two guide rails 20 in the same group are connected into a whole and wound around the roller 31, the guide rails 20 are matched with the annular groove 33, so that the guide rails 20 and the roller 31 can be conveniently assembled. Meanwhile, the problem that the guide rail 20 is separated from the roller 31 when the guide rail 20 is subjected to external force can be avoided.

Further, the second fixing frame 30b is also provided with a stop lever 32, and the stop lever 32 is used for preventing the problem that the guide rail 20 is forced to jump off the annular groove 33. A predetermined gap is reserved between the stopper 32 and the roller 31, and after the guide rail 20 passes through the roller 31, there is only a small slight gap between the guide rail 20 and the stopper 32, which is smaller than the thickness of the guide rail 20.

In another embodiment, as shown in fig. 1 and 2, the track 20 is a four-cable follower 10 comprising: the two supporting parts 13, the guide sleeves 11 are respectively arranged on the corresponding supporting parts 13, and the two guide rails 20 in the same group penetrate through the same supporting part 13; and two antifriction rollers 12 arranged side by side and connected between the two support parts 13, and a passage through which the cable 50 passes is defined by the two support parts 13 and the two antifriction rollers 12.

It can be understood that when the cable 50 pulls the cable follower 10 to ascend, the pulling force of the cable 50 acts on the antifriction rollers 12, the force applied to the antifriction rollers 12 is distributed on the two sets of guide rails 20, the guide rails 20 are applied with an acting force in the radial direction of the rollers 31, the guide rails 20 are prevented from being applied with an acting force in the axial direction of the rollers 31, and the guide rails 20 can be prevented from being axially displaced on the rollers 31, so as to avoid the problem that the cable follower 10 cannot slide on the guide rails 20.

Meanwhile, because the cable follower 10 is at the lowest end of the cable 50 due to the gravity of the cable follower 10, the cable 50 between the control cabinet and the cable follower 10 is completely arranged between the four guide rails 20, and even if the cable 50 shakes, the cable 50 is blocked by the guide rails 20 to limit the shaking range of the cable 50.

In the present embodiment, the guide bush 11 is provided integrally with the support portion 13. The number of machining processes for the guide bush 11 and the support portion 13 can be reduced. At the same time, the structure between the guide sleeve 11 and the support portion 13 can be made more firm.

In another embodiment, as shown in fig. 1 and 4, the anti-sloshing apparatus 100 for an elevator trailing cable further includes a tension unit 40, and the tension unit 40 is installed at least one fixed frame and directly acts on the guide rail 20 or the roller 31 for adjusting the tightness of the guide rail 20.

It can be understood that, when the guide rail 20 is a flexible guide rail and is connected between two fixed frames, the flexible guide rail is too loose, which may cause the cable follower 10 to slide on the flexible guide rail unsmoothly; the flexible guide rail is too tight, i.e. in a tight state for a long time, which reduces the service life of the flexible guide rail. The tightness of the flexible guide rail can be adjusted through the tensioning unit 40, and the problem that the flexible guide rail is too loose and too tight is avoided.

When the tension unit 40 is used to adjust the tightness of the guide rails 20, only one of the guide rails 20 in the same group may be required to be adjusted, or the two guide rails 20 may be adjusted separately.

Preferably, the tensioning unit 40 includes an adjusting rod 41 and a nut 42, and one end of the adjusting rod 41 is connected with the guide rail 20 or the roller 31, and the other end thereof passes through the first fixing frame 30a and is threadedly connected with the nut 42.

It can be understood that a through hole is opened on the first fixing frame 30a where the tensioning unit 40 is located, the adjusting rod 41 is provided with an external thread, and the nut 42 is provided with an internal thread matched with the external thread. One end of the adjusting rod 41, which is opposite to the guide rail 20, can penetrate through the through hole and is in threaded connection with the nut 42, the nut 42 can change the position of the adjusting rod 41 by rotating the nut 42, so that the position of the adjusting rod 41 on the first fixing frame 30a is changed, the guide rail 20 is pulled by the adjusting rod 41, and the effect of adjusting the tightness of the guide rail 20 can be achieved.

Or, the adjusting rod 41 is rotatably connected with the rotating shaft of the roller 31, the second fixing frame 30b is provided with a through hole, the adjusting rod 41 is provided with an external thread, and the nut 42 is provided with an internal thread matched with the external thread. One end of the adjusting rod 41, which is opposite to the roller 31, can penetrate through the through hole and is in threaded connection with the nut 42, the nut 42 can change the position of the adjusting rod 41 by rotating the nut 42, so that the position of the adjusting rod 41 on the second fixing frame 30 is changed, the roller 31 is pulled by the adjusting rod 41, and the effect of adjusting the tightness of the guide rail 20 can be achieved by changing the distance between the roller 31 and the first fixing frame 30 a.

Further, as shown in fig. 4, the tensioning unit 40 further includes an elastic member 43, and the elastic member 43 is sleeved on the adjusting rod 41 and is compressed between the nut 42 and the first fixing frame 30a where the tensioning unit 40 is located.

It will be appreciated that the resilient member 43 has a certain amount of compression. When the elastic member 43 is disposed between the nut 42 and the first fixing frame 30a, the elastic member 43 is pressed, and the elastic member 43 applies elastic force to the nut 42, so that the nut 42 has a force away from the first fixing frame 30a, and thus the adjusting rod 41 can be driven to pull the guide rail 20, so that the guide rail 20 is tightened on the two fixing frame supports, and the position of the nut 42 on the adjusting rod 41 can be adjusted, so that the compression amount of the elastic member 43 can be adjusted, and the tightness of the guide rail 20 can be adjusted by adjusting the compression amount of the elastic member 43.

In the present embodiment, the elastic member 43 is a spring, which is fitted over the adjustment lever 41, and one end of the spring abuts against the nut 42 and the other end abuts against the first holder 30a, so that the spring is pressed between the nut 42 and the first holder 30 a.

Of course, in other embodiments, the elastic member 43 may be a rubber or other damping elastic element. As long as the elastic member can adjust the tightness of the guide rail 20 by its own compression amount.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
