[0038] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0039] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] Embodiment 1: Figures 1 to 4 As shown, the high-precision elevator floor door operation device of the present application includes a mounting assembly 100, a guide assembly 200, a lifting component 300, a laser ranging assembly 400, a power assembly and a control unit.

[0042] The mounting assembly 100 includes a mounting telescopic rod 110 , a shaft rod 130 and two connecting plates 120 .

[0043] The telescopic rod 110 is installed as a bidirectional synchronous telescopic electric push rod.

[0044] It should be noted that the output ends of the telescopic rod 110 are located on both sides. The telescopic rod 110 is a prior art. The structure of the telescopic rod 110 can refer to the Chinese patent publication number CN207234607U.

[0045] The two connecting plates 120 are respectively disposed on two sides of the bottom of the housing where the telescopic rod 110 is mounted, and the shaft rod 130 is disposed between the two connecting plates 120 .

[0046] The shaft rod 130 and the installation telescopic rod 110 are arranged in parallel.

[0047] A plurality of annular grooves 131 are evenly formed on the shaft 130 .

[0048] It should be noted that the plurality of annular grooves 131 may be 4, 5, 6, 7, 8 annular grooves 131, etc. The specific number is selected according to actual needs and will not be described in detail here; the distance between two adjacent annular grooves 131 is selected according to actual needs, such as 10 cm, and the specific distance is not described in detail here.

[0049] Preferably, Figure 1 As shown, pads 140 are respectively arranged on the output ends of both sides of the installation telescopic rod 110 , and the pads 140 are arranged vertically to the installation telescopic rod 110 .

[0050] The material of the pad 140 can be rubber.

[0051] The guide assembly 200 includes a plurality of rope rings 210, a plurality of guide ropes 220 and a plurality of counterweights 230, and the rope rings 210, the guide ropes 220, the counterweights 230 and the annular grooves 131 are the same in number and correspond to each other.

[0052] The rope ring 210 is rotatably embedded in the corresponding ring groove 131 .

[0053] It should be noted that the width of the annular groove 131 is the same as the width of the rope ring 210 , so that the rope ring 210 will not be axially offset in the annular groove 131 .

[0054] One end of the guide rope 220 is fixedly connected to the outer wall of the corresponding rope ring 210 , and the other end of the guide rope 220 is fixedly connected to the corresponding counterweight block 230 .

[0055] It should be noted that the mass of the counterweight block 230 is selected according to actual needs and will not be described in detail here.

[0056] The lifting component 300, the laser ranging assembly 400 and the guide rope 220 are the same in number and correspond one to one.

[0057] The lifting component 300 is disposed on the bottom of the mounting telescopic rod 110 , and the lifting component 300 is located above the corresponding guide rope 1 220 .

[0058] The laser distance measuring assembly 400 is slidably disposed on the guide rope 220 , and the lifting component 300 controls the lifting and lowering of the laser distance measuring assembly 400 .

[0059] It should be noted that the laser ranging component 400 transmits data by wireless transmission, and a display terminal (not shown in the figure) may be provided therein, and the detection data can be transmitted to the display terminal.

[0060] like Figure 4 As shown, the lifting component 300 includes an electric rope winding box 310 and a retractable rope 320. The electric rope winding box 310 is installed at the bottom of the telescopic rod 110. The retractable rope 320 is wound in the electric rope winding box 310, and the end of the retractable rope 320 away from the electric rope winding box 310 is connected to the corresponding laser ranging component 400.

[0061] The electric rope reel box 310 includes a housing 311 , a driving component 312 and a reeling shaft 313 . The driving component 312 is installed inside the housing 311 , and an output shaft of the driving component 312 is coaxially connected to the reeling shaft 313 .

[0062] The bottom of the housing 311 is provided with an opening, and the opening is located below the winding shaft 313 .

[0063] The reel 313 is arranged parallel to the shaft 130 , and one end of the reel rope 320 away from the laser distance measuring assembly 400 is fixedly connected to the reel 313 , and the reel rope 320 is reeled on the reel 313 .

[0064] The driving component 312 may be a rotating motor.

[0065] It is understandable that the driving component 312 drives the reel 313 to rotate, thereby retracting and releasing the retracting rope 320.

[0066] It should be noted that the diameter of the guide rope 220 in this embodiment is 5 mm to 15 mm, and the retractable rope 320 is close to the guide rope 220.

[0067] It should be noted that the length of the guide rope 220 is selected according to actual needs, such as the length of the guide rope 220 is 2 meters.

[0068] The power assembly is used to provide energy for the operation of the device, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of various components of the device, preferably a programmable logic controller; all of which are prior arts and will not be described in detail here.

[0069] Specifically, in the actual operation process, the relevant personnel install the installation component 100 horizontally on the door frame of the elevator floor door, wherein the output ends on both sides of the telescopic rod 110 are installed against the upper part of the door frame, and under the action of the gravity of the counterweight block 230, the guide rope 220 is in a vertical state. After waiting for a period of time until the guide rope 220 and the counterweight block 230 are in a stable state, the lifting component 300 can control the position of the laser ranging component 400. At this time, the test end of the laser ranging component 400 faces the floor door, and the distance between the laser ranging component 400 and the floor door can be measured. The laser ranging component 400 is controlled by the lifting component 300 to measure the distance between the floor door and the floor door at different heights. At the same time, multiple laser ranging components 400 can perform measurements synchronously, and the measurement data is transmitted to the display terminal, and the measurement data is displayed.

[0070] It should be noted that a data processing system may be integrated inside the display terminal to compare and analyze multiple distance values ​​detected by the same laser ranging component 400 to obtain the difference between the maximum and minimum values, and to define a difference threshold. When the actual measured difference exceeds the threshold, it indicates that the floor door has a deformation or offset that exceeds the standard in the vertical direction.

[0071] It can be understood that the device can detect the deformation or offset of the floor door in the vertical direction, and the guide rope 220 can remain vertical under the action of the counterweight block 230. Even if the telescopic rod 110 is offset to a certain extent (failed to remain horizontal) during the installation process, measurement can be performed; it should also be noted that the distance data measured by different laser ranging components 400 at the same height can be used to feedback whether the floor door has a deformation or offset that exceeds the standard in the horizontal direction. Specifically, it can be evaluated whether the distance data in the horizontal direction changes linearly. If it changes linearly, it means that no deformation or offset occurs in the horizontal direction. At this time, an offset threshold can be set. When the actually measured horizontal distance data exceeds the offset threshold, it means that the floor door has a deformation or offset that exceeds the standard in the horizontal direction at that height.

[0072] The above data processing method is a commonly used processing method in the prior art and can be selected and adjusted according to actual needs. The specific selection is based on actual needs.

[0073] It should be noted that relevant personnel can measure on the side of the floor door away from the car, or on the side of the floor door close to the car.

[0074] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0075] 1. It solves the technical problem that the laser detection device in the prior art only has the detection capability in a single direction, resulting in an incomplete detection structure and difficulty in accurately reflecting the overall status of the landing door; it realizes the technical effect of not only detecting in a single direction, but also making the detection results more comprehensive and reflecting the overall status of the landing door;

[0076] 2. By using the laser distance measuring assembly 400, high-precision distance measurement can be achieved, thereby accurately reflecting the deformation or offset of the elevator door at different positions and heights;

[0077] 3. It can not only detect the deformation or offset of the door in the vertical direction, but also evaluate the deformation or offset of the door in the horizontal direction by comparing the measurement data of different laser ranging components 400 at the same height. This multi-dimensional detection capability provides more comprehensive information on the door status;

[0078] 4. The installation telescopic rod 110 in the device has a bidirectional synchronous telescopic function, which can adapt to elevator door frames of different sizes and shapes. In addition, even if the installation telescopic rod 110 is offset during the installation process, the guide rope 220 can remain vertical under the action of the counterweight block 230, so accurate measurement can still be performed;

[0079] 5. The electric rope reel box 310 is used to control the lifting and lowering of the laser distance measuring component 400, which is easy to operate and maintain; at the same time, the laser distance measuring component 400 transmits data by wireless transmission, which reduces the complexity of wiring and improves the reliability and flexibility of the system;

[0080] 6. It is suitable for elevator floor doors of various types and specifications. Through regular inspection and maintenance, the potential safety hazards of elevator floor doors can be discovered and dealt with in time to ensure the safe operation of the elevator.

[0081] Embodiment 2: In the above embodiment, when the laser ranging component 400 slides along the rope ring 210, if the sliding speed is fast, it may cause the laser ranging component 400 itself to shake to a certain extent, causing a certain error in the laser test result; the embodiment of the present application is optimized on the basis of the above embodiment.

[0082] like Figures 5 to 8 As shown, the shaft rod 130 is provided with a second annular groove 132 , and the number of the first annular groove 131 and the second annular groove 132 are the same and correspond one to one.

[0083] The second annular groove 132 is located at a side corresponding to the first annular groove 131 .

[0084] The guide assembly 200 further includes a plurality of rope rings 240, a plurality of guide ropes 250 and a plurality of counterweights 260, and the number of the ring groove 132, the rope ring 240, the guide ropes 250 and the counterweights 260 is the same and corresponds.

[0085] The second rope ring 240 is rotatably embedded in the corresponding second ring groove 132 .

[0086] It should be noted that the structures of the annular groove 131 and the annular groove 2 132 are the same, the structures of the rope ring 1 210 and the rope ring 2 240 are the same, the structures of the guide rope 1 220 and the guide rope 2 250 are the same, and the structures of the counterweight block 1 230 and the counterweight block 2 260 are the same.

[0087] One end of the second guide rope 250 is fixedly connected to the outer wall of the corresponding second rope ring 240 , and the other end of the second guide rope 250 is fixedly connected to the corresponding second counterweight block 260 .

[0088] It should be noted that the second counterweight 260 and the first counterweight 230 have the same mass.

[0089] It should be noted that the distance between the annular groove 131 and the annular groove 2 132 is selected according to actual needs so that the counterweight block 1 230 and the counterweight block 2 260 will not touch each other during use of the device. The distance between the annular groove 131 and the annular groove 2 132 is not described in detail here.

[0090] like Figure 5 and Figure 8 As shown, the laser ranging assembly 400 in this embodiment includes a mounting plate 410 and a laser ranging module 420 .

[0091] Two rope threading openings 411 are provided on the mounting plate 410 , and the two rope threading openings 411 are matched with the corresponding guide rope 1 220 and guide rope 2 250 , respectively, so that the mounting plate 410 is slidably disposed on a corresponding set of guide ropes 1 220 and guide ropes 2 250 .

[0092] The electric rope reel box 310 is located above the corresponding mounting plate 410 , and one end of the retractable rope 320 away from the electric rope reel box 310 is connected to the top of the mounting plate 410 .

[0093] The laser distance measurement module 420 is disposed on the bottom end of the mounting plate 410 .

[0094] It should be noted that the laser distance measuring assembly 400 is located between the two rope threading openings 411 , and the retractable rope 320 is connected at the center position between the two rope threading openings 411 .

[0095] It should be noted that in this embodiment, in order to ensure that the retractable rope 320, guide rope 1 220 and guide rope 2 250 remain parallel during use, the retractable rope 320 can be passed through the shaft 130, and a through opening (not shown in the figure) is correspondingly provided on the shaft 130. This structure is another optional implementation in this embodiment and is a common structure in the prior art, which will not be described in detail here.

[0096] It can be understood that the laser distance measuring assembly 400 slides along two guide ropes (guide rope 1 220 and guide rope 2 250) at the same time through the mounting plate 410. The two guide ropes are respectively rotatably embedded in the corresponding ring groove 1 131 and ring groove 2 132 by rope ring 1 210 and rope ring 2 240, and are kept in a vertical state by counterweight block 1 230 and counterweight block 2 260; the electric rope winding box 310 controls the retraction and release of the retractable rope 320, thereby driving the laser distance measuring assembly 400 to slide on the guide ropes; during the sliding process, the laser distance measuring assembly 400 continuously measures the distance between the elevator door and transmits the data to the display terminal for processing and analysis; due to the existence of the double rope guiding system, the laser distance measuring assembly 400 is more stable during the sliding process, reducing shaking and errors, and at the same time, it also improves the resistance to external interference, ensuring the accuracy and reliability of the measurement.

[0097] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0098] 1. The laser distance measurement module 420 slides along the two guide ropes at the same time, which significantly improves the stability of the laser distance measurement component 400 during the sliding process, reduces shaking, and thus reduces the laser test error caused by shaking;

[0099] 2. The double-rope guidance system not only improves stability, but also enhances the resistance of the laser ranging module 420 to external interference (such as wind, vibration, etc.), ensuring the accuracy and reliability of measurement even in complex or unfavorable environments;

[0100] 3. The laser distance measuring assembly 400 includes a mounting plate 410, and two rope threading openings 411 correspond to two guide ropes respectively, making the assembly structure more compact and reasonable. At the same time, the retractable rope 320 is connected to the top center of the mounting plate 410, ensuring the balance of the laser distance measuring assembly 400 during the sliding process;

[0101] 4. Due to the improved stability and enhanced anti-interference ability, the deformation or offset of the elevator door at different positions and heights can be measured more accurately, providing more reliable data support for the safe operation of the elevator.

[0102] Embodiment 3: If the above embodiment is used for a period of time, the surface of guide rope 1 220 or guide rope 2 250 may become rough, affecting the use of the device; the embodiment of the present application is optimized based on the above embodiment.

[0103] like Fig. 9 and Fig.10 As shown, the guide rope 220 in this embodiment includes an inner rope 221 and an outer film 222, and the outer film 222 is sleeved on the inner rope 221.

[0104] Among them, the two ends of the inner rope 221 in the guide rope 220 are respectively arranged on the corresponding rope ring 210 and the counterweight block 230, the bottom end of the outer film 222 in the guide rope 220 is connected to the corresponding counterweight block 230, and the top end of the outer film 222 in the guide rope 220 is sealed and sleeved on the corresponding inner rope 221.

[0105] The distance between the top of the outer membrane 222 of the guide rope 220 and the corresponding rope ring 210 is 2 cm to 5 cm.

[0106] The material of the outer film 222 may be plastic.

[0107] It should be noted that the guide rope 1 220 and the guide rope 2 250 have the same structure.

[0108] The cavity between the inner rope 221 and the outer film 222 is a filling cavity.

[0109] It should be noted that the filling cavity in this embodiment is a closed space and is filled with gas.

[0110] It can be understood that when the laser ranging assembly 400 slides along the guide ropes (guide rope 1 220 and guide rope 2 250), the outer film 222 acts as a protective layer, which can reduce the direct contact between the inner rope 221 and the external environment, thereby preventing the surface of the inner rope 221 from becoming rough or worn; at the same time, the smooth surface of the outer film 222 also helps to maintain the smooth sliding of the laser ranging assembly 400; the gas in the filling cavity plays a role of buffering and shock absorption, and can absorb the impact and vibration generated by the laser ranging assembly 400 during the sliding process to a certain extent, further improving the stability and reliability of the device.

[0111] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0112] 1. By providing the outer film 222 on the guide rope 1 220 and the guide rope 2 250, a protective layer is formed, which effectively prevents the surface of the guide rope (the guide rope 1 220 or the guide rope 2 250) from becoming rough or worn due to long-term use, significantly prolongs the service life of the guide rope, reduces the replacement frequency, and reduces the maintenance cost;

[0113] 2. The outer film 222 not only protects the inner rope 221, but also makes the friction between the guide rope and the laser distance measuring assembly 400 more uniform and stable, which helps to maintain the smoothness of the laser distance measuring assembly 400 during the sliding process and reduces the shaking and error caused by uneven friction;

[0114] 3. The gas in the filling cavity plays a role of buffering and shock absorption, and can absorb the impact and vibration generated by the laser ranging component 400 during the sliding process to a certain extent, further improving the stability and reliability of the device.

[0115] Embodiment 4: In the above embodiment, the guide rope 1 220 and the guide rope 2 250 have a certain stability through air pressure. There is still a certain operating space for this operation to improve stability. The embodiment of the present application is optimized on the basis of the above embodiment.

[0116] like Figures 11 to 14 As shown, the filling cavity in this embodiment is a closed space and is filled with filling paraffin 223, and the melting point of the filling paraffin 223 is 40 degrees Celsius to 50 degrees Celsius.

[0117] The first counterweight 230 and the second counterweight 260 are both provided with a heating component 231 therein, and the heating component 231 is used to heat the filling paraffin 223 in the corresponding filling cavity.

[0118] It should be noted that the first counterweight 230 and the second counterweight 260 have the same structure.

[0119] A heating wire (not shown in the figure) may be wound around the inner rope 221 , and the heating wire is connected to the corresponding heating component 231 .

[0120] The diameter of the heating wire may be 3 to 5 mm.

[0121] It should be noted that the heating wire and its arrangement method are prior arts and will not be described in detail here.

[0122] Preferably, Fig.11 and Fig.12 As shown, in the filling cavity of this embodiment, a plurality of annular partitions 224 are sequentially arranged, the inner circle of the partition 224 is sleeved on the inner rope 221 , and the outer circle of the partition 224 is connected to the inner wall of the outer film 222 .

[0123] It should be noted that the plurality of partitions 224 may be 10, 11, 12, 13, 14 partitions 224, etc. The specific number and position distribution are selected according to actual needs and will not be described in detail here.

[0124] Preferably, Fig.14 As shown, the interior of the rope ring 1 210 is hollow, and the interior of the rope ring 1 210 is filled with sticky paraffin 211.

[0125] The inner ring of the rope ring 1 210 is provided with a plurality of liquid outlet holes 212 , so that the sticky paraffin 211 in liquid state can adhere to the shaft 130 through the liquid outlet holes 212 .

[0126] It should be noted that in this embodiment, rope ring 1 210 and rope ring 2 240 have the same structure.

[0127] It should be noted that the plurality of liquid outlet holes 212 may be 3, 4, 5, 6, 7 liquid outlet holes 212, etc. The specific number, aperture and position distribution of the liquid outlet holes 212 are selected according to actual needs and will not be described in detail here.

[0128] The heating wire on the inner rope 221 can extend to the inside of the rope ring 1 210 or the rope ring 240 to heat the sticky paraffin 211.

[0129] It can be understood that when the guide rope (guide rope 1 220 or guide rope 2 250) needs to be adjusted at the beginning of use, the heating component 231 starts to work, heating the filled paraffin 223 to liquefy it and allowing the guide rope to be adjusted under the action of the counterweight (counterweight 1 230 or counterweight 2 260). At the same time, the sticky paraffin 211 inside the rope ring (rope ring 1 210 and rope ring 240) will also liquefy after heating and stick to the shaft 130 through the liquid outlet 212. When the guide rope and the counterweight are in a stable state, the heating component 231 is turned off to allow the sticky paraffin 211 and the filled paraffin 223 to cool down and solidify, thereby providing stable support for the guide rope.

[0130] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0131] 1. The melting point of the filling paraffin 223 is set between 40 degrees Celsius and 50 degrees Celsius. Under normal working conditions, the filling paraffin 223 remains solid, providing stable support for the guide rope (the first guide rope 220 and the second guide rope 250); when the guide rope needs to be adjusted, the filling paraffin 223 can be heated by the heating component 231 to liquefy it and allow the guide rope to be adjusted under the action of the counterweight (the first counterweight 230 or the second counterweight 260), and the adjustment is relatively flexible;

[0132] 2. Arranging a plurality of annular partitions 224 in the filling cavity not only enhances the stability of the filled paraffin 223, but also makes the filling process more uniform and controllable; the partitions 224 can prevent the filled paraffin 223 from excessively flowing after liquefaction to a certain extent, thereby maintaining the overall shape and stability of the guide rope;

[0133] 3. By setting sticky paraffin 211 inside the rope ring (rope ring 1 210 and rope ring 2 240) and making it stick to the shaft 130 after heating, a firm connection between the rope ring and the shaft 130 is achieved, which not only improves the reliability of the connection, but also reduces the errors and failures caused by loose connection. At the same time, the heating and liquefaction process of the sticky paraffin 211 also makes it easier for the rope ring to rotate on the shaft 130.

[0134] Embodiment 5: In the above embodiment, if wrinkles appear on the outer wall of the outer membrane 222 due to long-term use, the laser ranging component 400 may not be able to slide up and down smoothly; the embodiment of the present application is optimized based on embodiment 3.

[0135] like Fig.15 and Fig.16 As shown, an oil-immersed sponge 225 is provided in the filling cavity in this embodiment, and the oil-immersed sponge 225 is a sponge immersed in lubricating oil.

[0136] In this embodiment, a plurality of oil outlet holes 226 are arranged on the outer wall of the outer film 222 along the axial direction.

[0137] It should be noted that the plurality of oil outlet holes 226 may be 10, 15, 20, 25, 30 oil outlet holes 226, etc. The specific number, aperture and position distribution of the oil outlet holes 226 are selected according to actual needs and will not be described in detail here.

[0138] It can be understood that the guide ropes (guide rope 1 220 and guide rope 2 250) are pre-soaked in lubricating oil, and the oil-immersed sponge 225 absorbs and stores the lubricating oil; when the laser ranging component 400 slides on the outer film 222, due to a certain squeezing effect, the lubricating oil in the oil-immersed sponge 225 seeps out through the oil outlet 226; the seeped lubricating oil forms a thin lubricating film on the outer wall of the outer film 222, reducing the friction resistance between the laser ranging component 400 and the outer film 222; as the laser ranging component 400 slides up and down, the lubricating oil is continuously and evenly applied to the outer wall of the outer film 222 to maintain a long-term lubrication effect.

[0139] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0140] 1. By providing the oil-soaked sponge 225, the outer wall of the outer membrane 222 is continuously provided with lubricating oil, which effectively compensates for the problem of insufficient lubrication caused by long-term use or wear, and ensures that the laser ranging assembly 400 can maintain smooth up and down sliding for a long time;

[0141] 2. Lubricating oil can not only reduce friction, but also protect the surface of the outer film 222 and the laser ranging component 400 to a certain extent, reduce the wear caused by direct friction, and extend the service life of the equipment;

[0142] 3. The oil-impregnated sponge 225 serves as a storage and release medium for lubricating oil, and can release lubricating oil evenly and continuously, thereby avoiding local excessive wear caused by uneven lubrication.

[0143] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
