Description

Technical Field

[0001] This invention relates to the field of laser metrology technology, and in particular to a high-precision device for operating elevator landing doors. Background Technology

[0002] Elevators, as a core transportation facility in modern high-rise buildings, directly impact the safety and property of passengers through their daily operation. Elevator landing doors, a crucial component, not only separate the elevator shaft from the floor levels but also must effectively prevent passengers from falling in emergencies. Therefore, the integrity of their structure and the accuracy of their operation are paramount. Accurate and comprehensive inspection of landing door deformation, misalignment, or damage during routine maintenance, repairs, and periodic checks are key to ensuring safe elevator operation.

[0003] However, traditional elevator landing door inspection methods mostly rely on manual operation, such as using rulers and measuring tools for manual measurement. This method is not only time-consuming and labor-intensive, but also limited by human factors, making it difficult to guarantee measurement accuracy. With technological advancements, although some automated elevator landing door inspection devices have emerged, these devices still reveal many problems in practical applications. Some devices only have single-directional detection capabilities, such as only detecting deformation or displacement of the landing door in the vertical direction, while ignoring potential problems in the horizontal direction. This results in incomplete inspection results, making it difficult to accurately reflect the overall condition of the landing door. Summary of the Invention

[0008] Furthermore, the shaft has a second annular groove, and the number of the first annular groove and the second annular groove are the same and correspond one-to-one; the second annular groove is located on one side of the corresponding first annular groove; the guide assembly also includes multiple second rope loops, multiple second guide ropes, and multiple second counterweights, and the number of the second annular groove, the second rope loop, the second guide rope, and the second counterweight are the same and correspond one-to-one; the second rope loop is rotatably embedded in the corresponding second annular groove; the first annular groove and the second annular groove have the same structure; one end of the second guide rope is fixedly connected to the outer wall of the corresponding second rope loop, and the other end of the second guide rope is fixedly connected to the corresponding second counterweight.

[0038] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

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

[0040] Unless otherwise defined, 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 invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Example 1: As Figures 1 to 4 As shown, the high-precision elevator landing door operation device of this application includes an installation component 100, a guide component 200, a lifting component 300, a laser ranging component 400, a power component, and a control unit.

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

[0043] The telescopic rod 110 is 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 existing technology. The structure of the telescopic rod 110 can be found in Chinese Patent No. CN207234607U.

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

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

[0047] Multiple annular grooves 131 are evenly distributed on the shaft 130.

[0048] It should be noted that there may be 4, 5, 6, 7, or 8 annular grooves 131, etc. The specific number is selected according to actual needs and will not be detailed here. The distance between two adjacent annular grooves 131 is selected according to actual needs, such as 10 centimeters, and the specific distance will not be detailed here.

[0049] Preferred, such as Figure 1 As shown, pads 140 are respectively provided on the output ends of the telescopic rod 110 on both sides, and the pads 140 are perpendicular to the telescopic rod 110.

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

[0051] The guide assembly 200 includes multiple rope loops 210, multiple guide ropes 220, and multiple counterweights 230, and the number of rope loops 210, guide ropes 220, counterweights 230, and ring grooves 131 are the same and correspond to each other.

[0052] The rope loop 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 within 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 230.

[0055] It should be noted that the mass of counterweight 1230 is selected according to actual needs, which will not be detailed here.

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

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

[0058] The laser ranging component 400 is slidably mounted on the guide rope 220, and the lifting component 300 controls the lifting and lowering of the laser ranging component 400.

[0059] It should be noted that the laser ranging component 400 transmits data wirelessly, and may include a display terminal (not shown in the figure), on which the detection data can be transmitted.

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

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

[0062] The bottom of the housing 311 has an opening located below the winding shaft 313.

[0063] The take-up shaft 313 is arranged parallel to the shaft 130, and the end of the take-up rope 320 away from the laser ranging component 400 is fixedly connected to the take-up shaft 313, and the take-up rope 320 is wound on the take-up shaft 313.

[0064] The drive component 312 can be a rotary motor.

[0065] It is understandable that the drive component 312 drives the winding shaft 313 to rotate, thereby winding and unwinding the winding 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 take-up rope 320 is close to the guide rope 220.

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

[0068] The power component is used to supply power for the operation of the device, preferably an AC power source or a battery; the control unit is used to control the coordinated operation of the various components of the device, preferably a programmable logic controller; both are existing technologies and will not be described in detail here.

[0069] Specifically, in actual operation, the relevant personnel horizontally install the mounting component 100 on the door frame of the elevator landing door. The output ends of the telescopic rod 110 on both sides abut against the upper part of the door frame. Under the gravity of the counterweight 230, the guide rope 220 is in a vertical state. After a period of time until the guide rope 220 and the counterweight 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 landing door, and the distance between the laser ranging component 400 and the landing door can be measured. The lifting component 300 controls the laser ranging component 400 to measure the distance between itself and the landing door at different heights. At the same time, multiple laser ranging components 400 can perform measurements simultaneously. The measurement data is transmitted to the display terminal and displayed.

[0070] It should be noted that the display terminal may have an integrated data processing system that compares and analyzes 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 threshold for the difference. When the actual measured difference exceeds the threshold, it indicates that the door has deformed or shifted beyond the standard in that vertical direction.

[0071] Understandably, this device can detect deformation or displacement of the landing door in the vertical direction, and the guide rope 220 can remain vertical under the action of the counterweight 230. Even if the telescopic rod 110 deviates to a certain extent during installation (failing to remain horizontal), it can still be measured. In addition, it should be noted that the distance data measured by different laser ranging components 400 at the same height can be used to indicate whether the landing door has deformed or shifted beyond 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 displacement has occurred in the horizontal direction. At this time, an offset threshold can be set. When the actual measured horizontal distance data exceeds the offset threshold, it means that the landing door has deformed or shifted beyond the standard in the horizontal direction at that height.

[0072] The above data processing methods are commonly used in existing technologies and can be selected and adjusted according to actual needs. The specific selection should be based on actual needs.

[0073] It should be noted that the relevant personnel can take measurements either on the side of the landing door away from the car or on the side of the landing door closer to the car.

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

[0075] 1. This technology solves the problem that existing laser detection devices only have the ability to detect in one direction, resulting in an incomplete detection structure and difficulty in accurately reflecting the overall condition of the floor doors; it achieves the technical effect of not only detecting in one direction, but also providing more comprehensive detection results that can reflect the overall condition of the floor doors.

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

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

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

[0079] 5. The lifting and lowering of the laser ranging component 400 is controlled by an electric rope reel box 310, which is simple to operate and easy to maintain; at the same time, the laser ranging component 400 transmits data wirelessly, which reduces wiring complexity and improves the reliability and flexibility of the system.

[0080] 6. Applicable to elevator landing doors of various types and specifications. Through regular inspection and maintenance, potential safety hazards of elevator landing doors can be detected and addressed in a timely manner, ensuring the safe operation of the elevator.

[0081] Example 2: In the above example, if the laser ranging component 400 slides along the rope loop 210 at a fast speed, it may cause the laser ranging component 400 to shake, resulting in a certain error in the laser test result; the present application example is an optimization based on the above example.

[0082] like Figures 5 to 8 As shown, the shaft 130 has a second annular groove 132, and the number of annular grooves 131 and 132 are the same and correspond one-to-one.

[0083] Annular groove 2 132 is located on one side of the corresponding annular groove 1 131.

[0084] The guide assembly 200 also includes multiple rope loops 240, multiple guide ropes 250, and multiple counterweights 260, and the number of the ring grooves 232, rope loops 240, guide ropes 250, and counterweights 260 are the same and correspond to each other.

[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 ring groove 131 and ring groove 212 are the same, the structures of rope ring 1210 and rope ring 240 are the same, the structures of guide rope 1220 and guide rope 250 are the same, and the structures of counterweight 1230 and counterweight 260 are the same.

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

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

[0089] It should be noted that the spacing between annular groove 131 and annular groove 2132 is selected according to actual needs, so that counterweight 1230 and counterweight 260 will not touch during the use of the device. The spacing between annular groove 131 and annular groove 2132 will not be described in detail here.

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

[0091] The mounting plate 410 has two rope-threading openings 411, and the two rope-threading openings 411 are respectively matched with the corresponding guide rope 1 220 and guide rope 250, so that the mounting plate 410 is slidably set on the corresponding set of guide rope 1 220 and guide rope 250.

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

[0093] The laser ranging module 420 is mounted on the bottom of the mounting plate 410.

[0094] It should be noted that the laser rangefinder 400 is located between the two rope-threading ports 411, and the rope retraction and extension 320 is connected at the center between the two rope-threading ports 411.

[0095] It should be noted that in this embodiment, in order to ensure that the take-up rope 320, guide rope one 220 and guide rope two 250 remain parallel during use, the take-up rope 320 can pass through the shaft 130, and the shaft 130 is provided with a through hole (not shown in the figure). This structure is another optional implementation in this embodiment and is a common structure in the prior art, so it will not be described in detail here.

[0096] Understandably, the laser ranging component 400 slides simultaneously along two guide ropes (guide rope one 220 and guide rope two 250) via the mounting plate 410. These two guide ropes are rotatably embedded in corresponding annular grooves 131 and 132 by rope loop one 210 and rope loop two 240, respectively, and are kept vertical by counterweights 230 and 260. The electric rope winding box 310 controls the winding and unwinding of the rope 320, thereby driving the laser ranging component 400 to slide on the guide ropes. During the sliding process, the laser ranging component 400 continuously measures the distance to the elevator landing door and transmits the data to the display terminal for processing and analysis. Due to the existence of the dual-rope guiding system, the laser ranging component 400 is more stable during the sliding process, reducing swaying and errors. It also improves resistance to external interference, ensuring the accuracy and reliability of the measurement.

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

[0098] 1. The laser ranging module 420 slides along two guide ropes simultaneously, which significantly improves the stability of the laser ranging component 400 during the sliding process, reduces shaking, and thus reduces laser testing errors caused by shaking.

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

[0100] 3. The laser ranging component 400 includes a mounting plate 410, with two lanyard holes 411 corresponding to two guide ropes, making the component structure more compact and reasonable. Meanwhile, the take-up and release rope 320 is connected to the top center of the mounting plate 410, ensuring the balance of the laser ranging component 400 during sliding.

[0101] 4. Due to improved stability and enhanced anti-interference capabilities, it is possible to more accurately measure the deformation or displacement of elevator landing doors at different positions and heights, providing more reliable data support for the safe operation of elevators.

[0102] Example 3: In the above examples, if the process takes time, the surface of guide rope 220 or guide rope 250 may become rough, affecting the use of the device; the present application example is an optimization based on the above examples.

[0103] like Figure 9 and Figure 10 As shown, the guide rope 220 in this embodiment includes an inner rope 221 and an outer membrane 222, with the outer membrane 222 fitted over the inner rope 221.

[0104] In the guide rope 220, the two ends of the inner rope 221 are respectively set on the corresponding rope ring 210 and the counterweight 230. The bottom end of the outer membrane 222 in the guide rope 220 is connected to the corresponding counterweight 230. The top end of the outer membrane 222 in the guide rope 220 is sealed and sleeved on the corresponding inner rope 221.

[0105] In the guide rope 220, the distance between the top of the outer membrane 222 and the corresponding rope loop 210 is 2 to 5 centimeters.

[0106] The outer membrane 222 can be made of plastic.

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

[0108] The cavity between the inner rope 221 and the outer membrane 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] Understandably, when the laser ranging component 400 slides along the guide ropes (guide rope one 220 and guide rope two 250), the outer membrane 222, as a protective layer, 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 membrane 222 also helps to maintain the smooth sliding of the laser ranging component 400. The gas in the filling cavity plays a role in buffering and shock absorption, which can absorb the impact and vibration generated by the laser ranging component 400 during sliding to a certain extent, further improving the stability and reliability of the device.

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

[0112] 1. By setting an outer membrane 222 on guide rope 1 220 and guide rope 2 250, a protective layer is formed, which effectively prevents the surface of the guide rope (guide rope 1 220 or guide rope 2 250) from becoming rough or worn due to long-term use, significantly extending the service life of the guide rope, reducing the replacement frequency, and reducing maintenance costs.

[0113] 2. The outer membrane 222 not only protects the inner rope 221, but also makes the friction between the guide rope and the laser ranging component 400 more uniform and stable, which helps to maintain the smoothness of the laser ranging component 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 in buffering and shock absorption, which 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] Example 4: In the above examples, air pressure is used to give guide rope 1 220 and guide rope 250 a certain degree of stability. However, there is still some room for improvement in this operation. The present application example is an optimization based on the above examples.

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

[0117] Both counterweight 1 230 and counterweight 260 are equipped with heating components 231, which are used to heat the paraffin wax 223 filling the corresponding filling cavity.

[0118] It should be noted that counterweight 1 230 and counterweight 2 260 have the same structure.

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

[0120] The diameter of the heating wire can be 3 to 5 millimeters.

[0121] It should be noted that the heating wire and its setting method are existing technologies and will not be described in detail here.

[0122] Preferred, such as Figure 11 and Figure 12 As shown, in this embodiment, a plurality of annular partitions 224 are sequentially arranged in the filling cavity. The inner ring of the partition 224 is sleeved on the inner rope 221, and the outer ring of the partition 224 is connected to the inner wall of the outer membrane 222.

[0123] It should be noted that there may be 10, 11, 12, 13, or 14 compartments 224, etc. The specific number and location distribution are selected according to actual needs, and will not be detailed here.

[0124] Preferred, such as Figure 14 As shown, the inside of the rope loop 210 is hollow and filled with sticky paraffin wax 211.

[0125] The inner ring of the rope ring 210 has multiple liquid outlet holes 212, which allow the liquid adhesive paraffin 211 to adhere to the shaft 130 through the liquid outlet holes 212.

[0126] It should be noted that in this embodiment, the first rope loop 210 and the second rope loop 240 have the same structure.

[0127] It should be noted that there may be 3, 4, 5, 6, or 7 liquid outlet holes 212, etc. The specific number, diameter and location distribution of the liquid outlet holes 212 are selected according to actual needs, which will not be detailed here.

[0128] The heating wire on the inner rope 221 can extend into the rope loop 210 or the rope loop 240 to heat the sticky paraffin 211.

[0129] Understandably, when the guide rope (guide rope one 220 or guide rope two 250) needs to be adjusted at the beginning of practical use, the heating element 231 starts to work, heating the filling paraffin 223 to liquefy it and allowing the guide rope to be adjusted under the action of the counterweight (counterweight one 230 or counterweight two 260). At the same time, the adhesive paraffin 211 inside the rope loop (rope loop one 210 and rope loop two 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 element 231 is turned off to allow the adhesive paraffin 211 and the filling paraffin 223 to cool down and solidify, providing stable support for the guide rope.

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

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

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

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

[0134] Example 5: If wrinkles or other defects appear on the outer wall of the outer membrane 222 in the above examples due to long-term use, the laser ranging component 400 may not be able to slide smoothly up and down; this application example is an optimization based on Example 3.

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

[0136] In this embodiment, the outer wall of the outer membrane 222 is provided with a plurality of oil outlet holes 226 along the axial direction.

[0137] It should be noted that the number of oil outlet holes 226 can be 10, 15, 20, 25, or 30, etc. The specific number, diameter, and location distribution of the oil outlet holes 226 are selected according to actual needs, and will not be detailed here.

[0138] Understandably, the guide ropes (guide rope one 220 and guide rope two 250) are pre-soaked in lubricating oil, and the oil-soaked sponge 225 absorbs and stores the lubricating oil. When the laser ranging component 400 slides on the outer membrane 222, due to a certain amount of compression, the lubricating oil in the oil-soaked sponge 225 seeps out through the oil outlet 226. The seeping lubricating oil forms a thin lubricating film on the outer wall of the outer membrane 222, reducing the frictional resistance between the laser ranging component 400 and the outer membrane 222. As the laser ranging component 400 slides up and down, the lubricating oil is continuously and evenly coated on the outer wall of the outer membrane 222, maintaining a long-term lubrication effect.

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

[0140] 1. By setting an oil-soaked sponge 225, lubricating oil is continuously provided to the outer wall of the outer membrane 222, which effectively makes up for the problem of insufficient lubrication caused by long-term use or wear, and ensures that the laser ranging component 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 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, enabling it to release lubricating oil evenly and continuously, thus avoiding localized excessive wear caused by uneven lubrication.

[0143] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
