With the rapid development of cities and the rapid growth of buildings, elevators have become one of the main modes of daily transportation for people.

The terms "first," "second," and "third" are used solely for descriptive purposes and to distinguish technical features. They are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0030] like Figure 1As shown, this embodiment discloses a device for detecting the smooth operation of an elevator, comprising a box body 1, a magnetic field structure 2, a sliding structure 3, a positioning module, and a control module. Specifically, a cavity 11 is provided inside the box body 1, the magnetic field structure 2 is provided at both ends of the cavity 11, and the sliding structure 3 is horizontally slidable in the cavity 11 and is subjected to the repulsive force of the magnetic field structure 2 at both ends of the cavity 11; continue to refer to Figure 4 The positioning module 4 is electrically connected to the control module 5. The positioning module 4 is used to determine the relative position of the sliding structure 3 in the cavity 11. The control module 5 is used to receive the position information collected by the positioning module 4 and compare it to determine whether the elevator is running smoothly and the direction of shaking or tilting.

[0031] It can be understood that the sliding structure 3 in this embodiment is located in the magnetic field generated by the magnetic field structure 2, and the sliding structure 3 itself can generate a magnetic field, thereby being affected by the magnetic field repulsion force generated by the magnetic field structure 2. After the sliding structure 3 is balanced by force, it is located in the middle position of the cavity 11. The positioning module 4 can be used to collect the position information of the sliding structure 3. When the elevator shakes or tilts due to unstable operation, the position information of the sliding structure 3 will change. By comparing the real-time collected position information with the preset position threshold in the control module 5, it is possible to judge whether the elevator is running smoothly and the direction of shaking or tilting, which helps the staff to complete quick adjustments.

[0032] Preferably, the present embodiment discloses a sliding structure 3, which includes a slide rod 31 and a slider 32. Both ends of the slide rod 31 are fixed on the magnetic field structure 2, and the slider 32 can be horizontally slidably sleeved on the slide rod 31. The slide rod 31 is made of non-ferromagnetic material, and the slider 32 is made of ferromagnetic material. It can generate a magnetic field by itself, and both ends are respectively subjected to the repulsive force of the magnetic field structure 2. The slider 32 does not contact the inner wall of the cavity 11, so it will not be affected by the friction force of the inner wall of the cavity 11 during the sliding process. The positioning module 4 is used to determine the relative position of the slider 32 in the cavity 11.

[0033] Furthermore, the slider 32 includes a magnet, and the magnetic poles at both ends of the slider 32 are different, and the magnetic poles on the inner side of the magnetic field structure 2 are the same as the magnetic poles at the adjacent ends of the slider 32. Therefore, the two ends of the slider 32 are respectively subjected to the repulsive force of the magnetic field structure 2, so that the slider 32 is located in the middle position of the cavity 11 after the force is balanced.

[0034] Furthermore, the slider 32 is set to be in a circular ring shape, and the circular ring 321 can be horizontally slidably sleeved on the slide rod 31. The two ends of the circular ring 321 are set to be flat. After the circular ring 321 reaches force balance under the action of the magnetic field of the magnetic field structure 2, it is easier to maintain the middle position of the cavity 11.

[0035] Continue to refer Figure 3The slider 32 in this embodiment also includes grooves 322 and balls 323. At least three grooves 322 are arranged in a circular array on the inner wall of the ring 321. The grooves 322 are adapted to the balls 323. The balls 323 are slidably connected to the surface of the slide rod 31. Moreover, the balls 323 are made of non-ferromagnetic material, which reduces the friction between the slider 32 and the slide rod 31.

[0036] Furthermore, the positioning module 4 includes an infrared ranging sensor 41, which is arranged at both ends of the cavity 11 to measure the distance between the slider 32 and the two ends of the cavity 11; specifically, the infrared ranging sensor 41 is arranged above the magnetic field structure 2, and the top height of the ring 321 is greater than the top height of the magnetic field structure 2. The infrared ranging sensor 41 can collect the distance between it and the two ends of the ring 321, thereby obtaining the position information of the ring 321 in the cavity 11.

[0037] Continue to refer Figure 2 The box body 1 in this embodiment includes a transparent cover 12, which is arranged above the cavity 11, so as to facilitate observation of the movement trajectory and position of the slider 32; in addition, the cavity 11 is set to a vacuum environment, which can reduce the air resistance encountered by the slider 32 during movement.

[0038] Furthermore, the box body 1 also includes a horizontal level 13 and a vertical level 14. The horizontal level 13 is parallel to the bottom surface of the box body 1, and the vertical level 14 is perpendicular to the bottom surface of the box body 1. The center axis of the horizontal level 13 is parallel to the center axis of the slide rod 31, and the center axis of the vertical level 14 is perpendicular to the center axis of the slide rod 31. Moreover, the horizontal level 13 and the vertical level 14 are both provided on the front surface of the box body 1, which is conducive to leveling during installation in the elevator.

[0039] Furthermore, this embodiment also includes a touch screen 6 and a voice prompter 7. The touch screen 6 and the voice prompter 7 are electrically connected to the control module 5 respectively. The touch screen 6 can control the overall working status of the detection device and display the location information collected in real time by the positioning module 4. The voice prompter 7 can emit corresponding voice prompts according to the results of the judgment of the control module 5.

[0040] In addition, it also includes a wireless communication module 8 and a power supply module 9. The wireless communication module 8 and the power supply module 9 are electrically connected to the control module 5 respectively. The power supply module 9 is preferably an independently powered battery, which can be used without additional power connection, so that the detection device can be installed at any position in the elevator. The wireless communication module 8 can realize remote control of the detection device, which is conducive to long-term monitoring of the smooth operation of the elevator.

[0041] It is worth noting that, in this embodiment, a detection device is installed in the X-axis, Y-axis and Z-axis directions of the elevator respectively, and a suitable position threshold is preset in the control module 5 according to the position information collected by the slider 32 in the force balance state. When the elevator shakes during operation, the box body 1 shakes synchronously and drives the slider 31 to shake, and the repulsive force balance between the slider 32 and the magnetic field structure 2 at both ends of the slider 31 is broken, and the slider 32 slides back and forth on the slider 31. The control module 5 collects the position information of the slider 32 in real time according to the positioning module 4, and compares it with the preset position threshold to determine the direction of shaking or tilting during the operation of the elevator.

[0042] Thus, the functions of the elevator operation stability detection device in this embodiment are as follows:

[0043] (1) Stability judgment function

[0044] By placing the sliding structure in the magnetic field generated by the magnetic field structure, the sliding structure itself can generate a magnetic field, and thus be affected by the magnetic field repulsion generated by the magnetic field structure. After the force of the sliding structure is balanced, it is located in the middle of the cavity. The position information of the sliding structure can be collected using the positioning module. When the elevator shakes or tilts due to unstable operation, the position information of the sliding structure will change. By comparing the real-time collected position information with the preset position threshold in the control module, it can be determined whether the elevator is running smoothly and the direction of the shake or tilt, which helps the staff to complete quick adjustments.

[0045] (2) Reduce sliding resistance function

[0046] By setting the cavity as a vacuum environment, the air resistance encountered by the slider during movement can be reduced; at the same time, the sliding structure is set as a slide rod and a slider, the two ends of the slide rod are fixed on the magnetic field structure, and the slider can be horizontally slidably sleeved on the slide rod. The slider does not contact the inner wall of the cavity and will not be affected by the friction force of the inner wall of the cavity during sliding; in addition, the slider is set in a circular ring shape, and includes mutually compatible grooves and balls. The balls are slidably connected to the surface of the slide rod, so that the friction between the slider and the slide rod is smaller.

[0047] (3) Reset balance function

[0048] By placing a slider that can generate a magnetic field in the magnetic field structure, the magnetic poles at both ends of the slider are different, and the magnetic poles inside the magnetic field structure are the same as the magnetic poles at the adjacent end of the slider, so that non-contact force balance is achieved under the magnetic field repulsion generated by the magnetic field structure. When the elevator stops running, the slider can quickly reset to the force balance state, realizing the reset balance function, which is convenient to use and easy to adjust.

[0049] (4) Rapid leveling function

[0050] By arranging a horizontal level and a vertical level on the box body, the horizontal level is parallel to the bottom surface of the box body, the vertical level is perpendicular to the bottom surface of the box body, the center axis of the horizontal level is parallel to the center axis of the slide rod, the center axis of the vertical level is perpendicular to the center axis of the slide rod, and the horizontal level and the vertical level are both arranged on the front surface of the box body, which is conducive to rapid leveling during installation in the elevator.

[0051] (5) Remote monitoring function

[0052] By setting up a wireless communication module and a power supply module, the wireless communication module and the power supply module are electrically connected to the control module respectively. The power supply module is preferably an independently powered battery, which can be used without additional power connection, making it convenient for the detection device to be installed at any position in the elevator. The wireless communication module can realize remote control of the detection device, which is conducive to remote monitoring of the smooth operation of the elevator.
