Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to a device for protecting elevator steel ropes from swinging. Background Art

[0002] With the development of the elevator industry, the speed of elevators has been continuously improved, and many super high-rise buildings have emerged in cities. Strong winds can cause such buildings to shake and stimulate the elevator wire rope to swing. When the swing amplitude reaches a certain level, it will damage the components in the elevator shaft. The commonly used method at present is to use a tensioning device to tighten the elevator wire rope, but it invisibly increases the tension in the structure. Although the use of this device can reduce the damage to the elevator components caused by the swing of the wire rope, it increases the wear of the components and bearings, shortening the service life of the elevator.

[0003] In this regard, we can consider using sensor technology to make improvements. If we combine force or displacement sensors to obtain the swing force and swing amplitude of the wire rope, and use these data to optimize and improve the structure and layout of the elevator, we can not only improve the safety of the elevator and the riding experience, but also provide a reference for future elevator product development.

[0004] The information disclosed in the background part of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

The mounting plate 113 has a long hole 115 extending along the second direction. The guide device fixing bracket 120 and the resistance assembly fixing bracket 130 are installed to the mounting plate 113 through the long hole 115 and bolts. The long hole 115 has a certain length in the second direction so that the staff can adjust the position of the guide device fixing bracket 120 and the resistance assembly fixing bracket 130 on the mounting plate 113 of the base 110 along the second direction according to actual design requirements.

[0064] The two guide device fixing brackets 120 are located on both sides of the resistance component fixing bracket 130 in the second direction.

[0065] The guide device fixing bracket 120 is disposed on the base 110 , and the guide device fixing bracket 120 is used to install the guide device 200 .

[0066] The guide device fixing bracket 120 is made of C-shaped steel. The guide device fixing bracket 120 is installed to the long hole 115 of the mounting plate 113 of the base 110 by bolts. The staff can adjust the position of the guide device fixing bracket 120 on the mounting plate 113 of the base 110 along the second direction according to actual design requirements, and then adjust the position of the guide device 200 in the car 800 along the second direction.

[0067] The resistance assembly fixing bracket 130 is disposed on the base 110 , and the resistance assembly fixing bracket 130 is used to install the resistance assembly 700 .

[0068] like Figure 3 and Figure 4 As shown, the resistance assembly fixing bracket 130 is made of U-shaped steel.

[0069] The resistance assembly fixing bracket 130 includes a bottom plate 131 , a side plate 132 , and a side plate 133 which are formed in one piece, and the side plates 132 and 133 are located at both sides of the bottom plate 131 .

[0070] The bottom plate 131 is mounted to the long hole 115 of the mounting plate 113 of the base 110 by means of bolts.

[0071] The side panel 133 is used to install the end stopper 140, and the side panel 133 has a long hole 134 extending along the first direction, and the long hole 134 has a certain length in the second direction. The staff can adjust the position of the end stopper second connecting plate 142 introduced later on the side panel 133 along the first direction to change the position of the end stopper 140 along the first direction, and then adjust the position of the resistance assembly 700 in the car 800 in the first direction, thereby adjusting the resistance that the resistance assembly 700 can provide to the movable assembly 300.

[0072] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the end stop 140 is L-shaped.

[0073] like Figure 3 and Figure 4 As shown, the end stopper 140 is disposed on the resistance assembly fixing bracket 130 , and the resistance assembly 700 is mounted on the resistance assembly fixing bracket 130 through the end stopper 140 .

[0074] Specifically, the end stopper 140 includes an end stopper first connecting plate 141 and an end stopper second connecting plate 142 which are formed in one piece.

[0075] The second connecting plate 142 of the end stopper is bolted to the long hole 134 of the side plate 133 of the resistance assembly fixing bracket 130. The long hole 134 has a certain length in the second direction. The staff can adjust the position of the second connecting plate 142 of the end stopper on the side plate 133 of the resistance assembly fixing bracket 130 along the first direction according to actual design requirements to change the position of the end stopper 140 in the first direction, thereby adjusting the required resistance.

[0076] The first connecting plate 141 of the end stopper is used for installing the guide device 200 .

[0077] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the fixing assembly 100 further includes: a dust cover 150, which is installed on the base 110. The dust cover 150 is used to prevent the complex environment in the hoistway from damaging the components on the base 110, and can also prevent the components on the base 110 from falling and damaging the hoistway components of the elevator.

[0078] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the fixed component 100 further includes: a shock-absorbing rubber 160, which is arranged between the bottom plate 111 of the base 110 and the car 800. The shock-absorbing rubber 160 can reduce the impact of the vibration noise generated when the wire rope 600 touches the movable component 300 on the elevator.

[0079] In an exemplary embodiment, Figure 3 As shown, the guide device 200 includes two guide rods, namely, a guide rod 201 and a guide rod 202 , a portion of each guide rod is mounted on a guide device fixing bracket 120 , and another portion of each guide rod extends to the outside of the car 800 .

[0080] The guide device 200 may be composed of a rod and a sliding bearing, or other guide structures such as a guide rail may be used.

[0081] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the movable assembly 300 includes: a frame 310, the frame 310 is mounted to the guide device 200, and can slide along the guide device 200. The frame 310 includes a first frame plate 311, a second frame plate 312, a third frame plate 313, and a fourth frame plate 314 connected in sequence. Among them, the first frame plate 311 is closest to the fixed assembly 100, and the third frame plate 313 is farthest from the fixed assembly 100.

[0082] The frame 310 surrounds the wire rope 600, that is, the wire rope 600 runs within the frame 310. When the wire rope 600 shakes, the wire rope 600 can hit the frame first plate 311 and the frame third plate 313.

[0083] The first frame plate 311 and the third frame plate 313 are mounted to another portion of the guide rods 201 , 202 and can slide along the guide rods 201 , 202 , and the second frame plate 312 and the fourth frame plate 314 are located between the guide rods 201 and 202 .

[0084] The movable assembly 300 further includes a gasket 320, which can be detachably mounted on the inner surface of the frame 310 (i.e., the first frame plate 311, the second frame plate 312, the third frame plate 313, and the fourth frame plate 314). The gasket 320 can reduce abnormal noise and reduce wear on the frame 310 and the wire rope 600. When the gasket 320 is severely worn, the gasket 320 can be replaced more conveniently, which is convenient for later maintenance.

[0085] The material of the gasket 320 can be nylon, rubber, etc.

[0086] The detection device 400 can be mounted on the mounting plate 113 of the base 110, the guide device fixing bracket 120 or the resistance assembly fixing bracket 130. The detection device 400 can use a non-contact displacement sensor 402 or a contact sensor 401, or can use both types of sensors at the same time to obtain more detailed swing data. The contact sensor 401 can be a contact displacement sensor or a contact pressure sensor. The detection device 400 is electrically connected to the control system of the elevator.

[0087] The limit switch 500 may be mounted to the mounting plate 113 of the base 110, the guide device fixing bracket 120, or the resistance assembly fixing bracket 130. The limit switch 500 is electrically connected to the control system of the elevator.

[0088] The steel wire rope 600 may be a traction steel wire rope, a compensating steel wire rope, a speed limiter steel wire rope or other steel wire ropes.

[0089] exist Figures 1 to 4 In the embodiment of the present invention, the resistance assembly 700 includes a support rod and a spiral spring sleeved on the support rod. In other embodiments, the resistance assembly 700 can also be selected from hydraulic rods, gas pressure rods, etc.

[0090] exist Figures 1 to 4 In the embodiment, the resistance assembly 700 can adjust the required resistance by increasing or decreasing the spring or changing the position of the end stopper 140 in the first direction.

[0091] The elevator wire rope swing protection device of the utility model implementation scheme has two modes: a detection mode and a protection mode.

[0092] The elevator wire rope swing protection device of the utility model implementation scheme is suitable for the situation of installing and maintaining elevators.

[0093] In detection mode, if Figure 3 As shown, the detection device 400 is first installed on the mounting plate 113 of the base 110, the guide device fixing bracket 120 or the resistance component fixing bracket 130, and the detection device 400 is electrically connected to the control system of the elevator, and then the frame first plate 311 of the frame 310 of the movable component 300 is pressed against the wire rope.

[0094] During the movement of the elevator, the steel wire rope 600 swings and pushes the movable assembly 300 to generate displacement, and the displacement or pressure data is recorded by the detection device 400. After the movable assembly 300 generates displacement, the resistance provided by the resistance assembly 700 can reset the movable assembly 300.

[0095] In the detection mode, the resistance assembly 700 is only required to have the function of resetting the movable assembly 300 after the wire rope 600 swings. Therefore, if there is a reset spring inside the contact sensor 401, the resistance assembly 700 can be removed.

[0096] After the swing data of the wire rope 600 is known or the swing data of the wire rope 600 is measured through the detection mode, the elevator wire rope swing protection device of the embodiment of the utility model can be adjusted to the protection mode. Specifically, the detection device 400 is removed, and the limit switch 500 is installed on the mounting plate 113 of the base 110, the guide device fixing bracket 120 or the resistance component fixing bracket 130, and then the limit switch 500 is electrically connected to the control system of the elevator.

[0097] When set to the protection mode, the inner side of the movable component 300 (i.e., the first plate 311 of the frame) is fixed at a preset maximum allowable swing position. During the movement of the elevator, the swing amplitude of the wire rope 600 is greater than the maximum allowable swing amplitude. The movable component 300 is first released from the resistance component 700 and the coil spring of the resistance component 700 is compressed. The coil spring of the resistance component 700 provides resistance to the movable component 300 to slow down the swinging speed of the wire rope 600, and finally contacts the limit switch 500 at the end, and the limit switch 500 is triggered. After the limit switch 500 is triggered, a trigger signal is generated and the trigger signal is sent to the control system of the elevator, causing the elevator to stop or slow down.

[0098] Specifically, the steel wire rope 600 swings toward the elevator car 800, and the movable assembly 300 does not move when the swing degree is small.

[0099] When the swing degree is medium, the steel wire rope 600 pushes the movable assembly 300 to move toward the car 800 in a direction close to the fixed assembly 100 , and the movable assembly 300 contacts the resistance assembly 700 and is subjected to the reaction force of the resistance assembly 700 .

[0100] When the swing degree is large, the movable component 300 has completely overcome the reaction force of the resistance component 700, thereby threatening the safety of the car 800 and the shaft components. The limit switch 500 is compressed and actuated to generate a trigger signal, and the trigger signal is sent to the control system of the elevator, causing the elevator to stop or slow down.

[0101] The sensitivity of the protection can be adjusted by the resistance in the resistance assembly 700, the position of the limit switch 500, and the distance between the wire rope 600 and the inner side of the movable assembly 300 (ie, the first frame plate 311) when passing through.

[0102] In the above embodiment, the detection device 400 is first installed on the fixed assembly 100 of the elevator wire rope sway protection device, and after the monitoring is completed, the detection device 400 is replaced by the limit switch 500. In other embodiments, the detection device 400 and the limit switch 500 can also be installed on the fixed assembly 100 at the same time.

[0103] Various super-high-rise buildings emerge in cities. The higher the building, the greater the impact of strong winds. In strong wind weather, the top of the building may swing by tens of centimeters. At the same time, ultra-high-speed elevators are affected by the "chimney effect" in the shaft, and the wire rope swings frequently. If the elevator wire rope swing protection device of the implementation scheme of the utility model is used, such swing amplitude can be effectively monitored and measures can be taken in advance, thereby ensuring the safe operation of the elevator and extending the service life of the elevator.

[0104] The multifunctional elevator wire rope swing protection device provided by the utility model has various functions and is easy to install and debug. It can effectively monitor the swing of the wire rope under various working conditions when applied in super high-rise buildings, and can take measures to protect elevator components when the swing amplitude is large.
