DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0028] Embodiment 1: An elevator wire rope safety detection device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.12As shown, it includes a tension detection mechanism 6 and an appearance detection mechanism 7. The tension detection mechanism 6 is installed on the top of the elevator car 4 near the side of the counterweight frame 5. The appearance detection mechanism 7 is installed on the channel steel 1 used to fix the traction machine 2 in the machine room, and the appearance detection mechanism 7 is located outside the wire rope 3. The control cabinet 8 is installed in the elevator machine room. The tension detection mechanism 6 includes a base 601, a linear module 602, a first electric push rod 603, a connecting piece 604 and a detector 605. The base 601 serves as a supporting structure for the entire tension detection mechanism 6. The base 601 is fixedly installed on the top of the car 4 by bolts, and both ends of the linear module 602 are movably installed on the base 6 through bearings. 01 top, allowing the linear module 602 to rotate with the centers of the bearings at both ends as the axis, the two ends of the first electric push rod 603 are respectively movably connected to the linear module 602 and the base 601, and the linear module 602 is connected with a connecting piece 604 set vertically thereto. The telescopic movement of the first electric push rod 603 is used to push the linear module 602 to rotate, so that the connecting piece 604 partially extends out of the top of the car 4 and is located on one side of the counterweight side wire rope 3; when the connecting piece 604 is extended, it will be located on the moving track of the counterweight frame 5. Therefore, before the elevator runs, it is necessary to use the first electric push rod 603 to push the linear module 602 and the connecting piece 604 to rotate to ensure that the connecting piece The connecting member 604 is turned away from the moving track of the counterweight frame 5 to avoid potential collision risks; a detector 605 is installed on the connecting member 604, and the detector 605 can slide on the connecting member 604. When the connecting member 604 extends out of the top of the car 4, the detector 605 is driven to move on the connecting member 604 so that the detector 605 is aligned with the wire rope 3. When the connecting member 604 is retracted to the top of the car 4, the detector 605 is driven to reset; the appearance detection mechanism 7 includes a mounting frame 701, a slide rail 703, a sliding rod 704, a detector 705 and a propulsion mechanism 706. The mounting frame 701 is connected to the channel steel 1 by bolts, and two slide rails 703 are installed at the lower part of the mounting frame 701. 03, a sliding rod 704 is slidably connected between the two sliding rails 703, and the sliding rod 704 can move left and right along the sliding rails 703. The top of the sliding rod 704 is equipped with detectors 705 equal to the number of wire ropes 3. The detector 705 is used to monitor the status of the elevator wire rope 3 in real time, which is an important component to ensure its safety. A propulsion mechanism 706 for pushing the sliding rod 704 to move left and right is installed on the mounting frame 701, so that the detector 705 is close to or away from the elevator wire rope 3. The control cabinet 8 has a built-in wireless transmission module, which is used to connect to a mobile phone terminal. The first electric push rod 603 and the linear module 602 are both electrically connected to the control cabinet 8.

[0029] Initially, the tension detection mechanism 6 is in a non-detection state. In this state (such as Fig.12As shown in the figure, the telescopic rod of the first electric push rod 603 is in an extended state, the linear module 602 rotates sideways, the detector 605 is located at one end of the connector 604 close to the linear module 602, and the connector 604 does not exceed the top edge of the car 4 to avoid interference between the connector 604 and the counterweight frame 5 when the elevator is running. When it is necessary to check the tension of the wire rope 3, the elevator car 4 is stopped at two-thirds of the height of the hoistway, and the power supply of the elevator is cut off through the control cabinet 8 to ensure that the elevator is stationary. Control the telescopic rod of the first electric push rod 603 to retract, so that the connecting piece 604 is parallel to the top of the car 4, and then control the linear module 602 to drive the connecting piece 604 to move toward the direction of the wire rope 3. After the connecting piece 604 contacts the wire rope 3, control the detector 605 to slide along the connecting piece 604, so that multiple detectors 605 correspond to multiple wire ropes 3 one by one, and measure the tension of multiple wire ropes 3 through the detector 605. The measurement results are fed back to the control cabinet 8 through the detector 605, and then the data are transmitted to the analysis terminal for data analysis through the built-in wireless transmission module of the control cabinet 8. The data are analyzed and processed in detail through the terminal so that the detection personnel can view and understand the data conveniently and quickly. When it is necessary to check the wear degree of the steel wire rope 3, it can be carried out simultaneously with the tension test of the steel wire rope 3, and the propulsion mechanism 706 can be controlled to drive the detector 705 to move toward the direction of the steel wire rope 3, so that multiple detectors 705 correspond to multiple steel wire ropes 3 one by one, and the detector 705 is started to measure the diameter of the steel wire rope 3. In this way, its wear condition can be evaluated. When the test is completed, the propulsion mechanism 706 is started to drive the detector 705 to reset, and the first electric push rod 603 and the linear module 602 are controlled to reset, so that the tension detection mechanism 6 is also restored to the initial non-detection state, ready for the next elevator operation.

[0030] like Fig.10 As shown, it also includes a side panel 707, a first camera 708 and a fill light 709. The side panel 707 is connected to the bottom of the mounting frame 701. The first camera 708 and the fill light 709 are installed on the side of the side panel 707 close to the wire rope 3. The fill light 709 is located above the first camera 708. The fill light 709 and the first camera 708 are both electrically connected to the control cabinet 8.

[0031] When the appearance inspection of the steel rope 3 of the elevator is carried out, the elevator starts the maintenance mode, the elevator moves in the shaft, the first camera 708 is facing each steel rope 3, the control cabinet 8 controls the first camera 708 to record the surface status video of the steel rope 3, and the fill light 709 automatically turns on to enhance the lighting. When the elevator completes the operation of the entire shaft, the control cabinet 8 will immediately compress and package the recorded video data through the built-in wireless transmission module, and synchronously transmit it to the data analysis terminal. After arriving at the data analysis terminal, professional software will perform detailed analysis and processing on these image data. The software can identify possible wear, breakage or other defects, and generate easy-to-understand reports and charts to help inspection personnel quickly and accurately evaluate the status of the steel rope, so as to make necessary maintenance or replacement decisions.

[0032] like Figure 8 As shown, it also includes a limit shaft 702 and a separation disk 710. Two limit shafts 702 are symmetrically arranged on the upper and lower sides of the mounting frame 701, and each limit shaft 702 is connected to a plurality of separation disks 710 along its axial direction. A guide gap for a single steel wire rope 3 to pass through is formed between adjacent limit shafts 702 and separation disks 710, wherein the limit shaft 702 away from the side of the mounting frame 701 can be disassembled to facilitate placing the steel wire rope 3 in the gap between the two limit shafts 702. Multiple steel wire ropes 3 are arranged in an evenly spaced state after being separated by the separation disks 710 and the limit shafts 702. The spacing constitutes a measuring gap for the main scale and the secondary scale of the electronic vernier caliper 7052 to be inserted. The steel wire ropes 3 are separated by the limit shafts 702 and the separation disks 710, so that the steel wire ropes 3 can be neatly arranged at an even spacing, and convenience is provided for the subsequent use of the electronic vernier caliper 7052 for precise measurement.

[0033] Embodiment 2: Based on embodiment 1, Figure 3-Figure 5 As shown, the connecting member 604 includes a support arm 6041, a guide rail 6042 and a support plate 6043. The guide rail 6042 is connected to the support arm 6041 on one side close to the wire rope 3, and is connected to the support plate 6043 on the other side. The end of the support arm 6041 facing the wire rope 3 is flat. The detector 605 is movably connected to the guide rail 6042, and the support plate 6043 is used to provide support for the movement of the detector 605.

[0034] like Figure 7As shown, the detector 605 includes a sliding frame 6051, a second electric push rod 6052, a sliding plate 6053, a thrust meter 6054, an arc push block 6055, an infrared sensor 6056 and an electric wheel 6057. The number of sliding frames 6051 is equal to the number of steel wire ropes 3, and they are all slidably connected to the guide rail 6042. Each sliding frame 6051 is slidably connected to a sliding plate 6053. The second electric push rod 6052 is installed on the sliding frame 6051, and its telescopic rod is connected to the sliding plate 6053. The second electric push rod 6052 is located on the sliding plate 6053. 053 and the sliding frame 6051, the thrust meter 6054 is installed on the end of the sliding plate 6053 close to the wire rope 3, and the thrust rod of the thrust meter 6054 is connected with an arc-shaped push block 6055 adapted to the wire rope 3. An infrared sensor 6056 is installed on the top of each thrust meter 6054, and an electric wheel 6057 is installed at the bottom of the sliding frame 6051. The electric wheel 6057 is in contact with the top of the support plate 6043. The thrust meter 6054, the infrared sensor 6056, the second electric push rod 6052 and the electric wheel 6057 are all electrically connected to the control cabinet 8.

[0035] When the first electric push rod 603 is shortened to put the connecting member 604 in the detection state, the linear module 602 is started to drive the support arm 6041, the guide rail 6042, the support plate 6043 and the detector 605 to move in the direction of the wire rope 3, the support arm 6041 contacts the plurality of wire ropes 3, the linear module 602 is closed, the infrared sensor 6056 is turned on, and the electric wheels 6057 on each detector 605 are started in sequence from the far end to the near end of the guide rail 6042. The electric wheels 6057 cooperate with the support plate 6043 to drive the sliding frame 6051 moves along the guide rail 6042 toward the end away from the linear module 602. When the infrared sensor 6056 passes the position of the steel wire rope 3, the infrared sensor 6056 senses once. When the number of sensing times of the infrared sensor 6056 of the outermost detector 605 is equal to the number of steel wire ropes 3, the infrared sensor 6056 feeds back the signal to the control cabinet 8, and the control cabinet 8 controls the electric wheel 6057 on the detector 605 to close. At this time, the arc-shaped push block 6055 on the detector 605 is aligned with the steel wire rope 3 farthest from the car 4. The control cabinet 8 then controls the electric wheels 6057 on other detectors 605 in turn to move the detector 605. When the number of sensing times of the infrared sensor 6056 on it is equal to the total number of steel wire ropes 3 minus 1, the infrared sensor 6056 feeds back the signal to the control cabinet 8, and the control cabinet 8 controls the electric wheel 6057 on the detector 605 to close. By analogy, each detector 605 is aligned with each steel wire rope 3. Then start the second electric push rod 6052 to shorten and drive the sliding plate 6053 to move, and the thrust meter 6054 moves accordingly, and the arc-shaped push block 6055 pushes multiple steel ropes 3 to move the same distance. Each thrust meter 6054 feeds back the measurement data to the control cabinet 8, and the control cabinet 8 transmits the data to the mobile phone terminal of the inspector through the wireless transmission module. After the inspection is completed, the second electric push rod 6052 is controlled to shorten, and then the electric wheel 6057 is controlled to drive the reset detector 605 to reset.

[0036] Embodiment 3: Based on embodiment 2, Figure 9-11As shown, the detector 705 includes a connecting plate 7051, an electronic vernier caliper 7052, an electromagnet 7053, a magnetic block 7054, a tension spring 7055, a digital display screen 7056, an L-shaped plate 7057 and a second camera 7058. The connecting plates 7051 are connected to the sliding rod 704 at intervals, and the number of the connecting plates 7051 is equal to the number of the wire ropes 3. An electronic vernier caliper 7052 is installed on each connecting plate 7051. The heights of the multiple connecting plates 7051 gradually decrease from the back to the front, so that the electronic vernier calipers 7052 are staggered up and down to avoid being blocked by the adjacent electronic vernier calipers 7052 during measurement. The sub-scale of the electronic vernier caliper 7052 is fixedly connected to the upper part of the connecting plate 7051. The electronic vernier caliper 70 An electromagnet 7053 is connected to the secondary scale of 52, and a magnetic block 7054 is connected to the main scale. The positions of the electromagnet 7053 and the magnetic block 7054 correspond to each other, so that the tail of the secondary scale and the main scale are connected through a tension spring 7055. When the electromagnet 7053 is energized, it will generate a force that repels the magnetic block 7054, so that the secondary scale moves toward the main scale, and the tension spring 7055 is stretched. After the electromagnet 7053 is powered off, the secondary scale is reset by the tension spring 7055. A digital display screen 7056 is provided on the top of the secondary scale, an L-shaped plate 7057 is provided on the top of the connecting plate 7051, and a second camera 7058 located above the digital display screen 7056 is provided at the bottom of the L-shaped plate 7057. The second camera 7058 and the electromagnet 7053 are both electrically connected to the control cabinet 8.

[0037] like Fig. 9 and Fig.11 As shown, the propulsion mechanism 706 includes a propulsion motor 7061, a cam 7062, a propulsion shaft 7063 and a propulsion frame 7064. The propulsion motor 7061 is installed on the top of the mounting frame 701, the cam 7062 is connected to the output shaft of the propulsion motor 7061, the propulsion shaft 7063 is connected to the end of the output shaft of the cam 7062 away from the propulsion motor 7061, the propulsion frame 7064 is connected to the sliding rod 704, a slide groove 7065 is provided in the propulsion frame 7064, and the propulsion shaft 7063 is located in the slide groove 7065.

[0038] The control cabinet 8 controls the propulsion motor 7061 to rotate 180 degrees, and the propulsion motor 7061 drives the cam 7062 to rotate, and the propulsion frame 7064 and the sliding rod 704 are pushed to move in the direction of the wire rope 3 through the cooperation of the propulsion shaft 7063 and the slide groove 7065, so that the main scale and the secondary scale of each electronic vernier caliper 7052 are respectively located on both sides of the wire rope 3, and the electromagnet 7053 is controlled to be energized. The electromagnet 7053 is energized to generate repulsive force with the magnetic block 7054, pushing the main scale to move, and the tension spring 7055 is stretched. The main scale drives the wire rope 3 to move in the direction of the secondary scale, so that the main scale and the secondary scale clamp the wire rope 3, and the diameter of the wire rope 3 is measured. The control cabinet 8 controls the second camera 7058 to start, and the second camera 7058 takes a picture of the value displayed by the electronic vernier caliper 7052, and transmits it to the user's mobile phone terminal or data analysis terminal through the wireless transmission module. On the data analysis terminal, professional software will process and analyze these photos. First, the image recognition technology automatically extracts the value displayed by the electronic vernier caliper 7052 from the photo and converts it into digital information for further analysis. Then, the software evaluates the diameter value according to the preset standards and parameters (such as the rated diameter of the wire rope, the allowable tolerance range, etc.). Then, the control cabinet 8 controls the electromagnet 7053 to be powered off, and the electromagnet 7053 loses the repulsive force on the magnetic block 7054, and the main scale is pulled back to the original position under the action of the tension spring 7055. The control cabinet 8 controls the propulsion motor 7061 to rotate 180 degrees in the opposite direction, so that the sliding rod 704 is reset, and the main scale and the auxiliary scale of the electronic vernier caliper 7052 are away from the wire rope 3, avoiding friction between the wire rope 3 and the electronic vernier caliper 7052.

[0039] like Figure 8 As shown, it also includes a contact switch 607, an elastic member 608 and a contact plate 609. A groove 606 is provided on the side of the support arm 6041 close to the wire rope 3. The groove 606 is located at the end of the support arm 6041 away from the linear module 602. A contact switch 607 is installed in the middle of the groove 606. A contact plate 609 is hingedly connected to the upper part of the groove 606. The two sections of the contact plate 609 are elastically connected to the inner wall of the groove 606 through the elastic member 608. In this embodiment, the elastic member 608 is a spring, and the contact switch 607 is electrically connected to the control cabinet 8.

[0040] The linear module 602 drives the support arm 6041 to move toward the wire rope 3. When the contact plate 609 contacts the wire rope 3, due to obstruction, the contact plate 609 is forced to retract toward the groove 606, the elastic member 608 is compressed, and the contact plate 609 triggers the contact switch 607, generating an electrical signal. The contact switch 607 sends the signal to the control cabinet 8, and the control cabinet 8 controls the linear module 602 to close.
