[0025] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] See also Figures 1-9 The embodiment of the present invention provides a technical solution: an elevator operation status detection device, including a mounting frame 1, the mounting frame 1 is in a "cross" shape, an adjustment component 3 is installed on the bottom wall of the mounting frame 1, an integrated controller 2 is installed on the left side of the top wall of the mounting frame 1, a lifting component 4 is fixedly installed on the top wall of the mounting frame 1, the bottom end of the lifting component 4 passes through the mounting frame 1 and is fixedly connected to the top of the adjustment component 3 through a bearing, an opening and closing detection component 6 is installed on the outer wall of the lifting component 4, and a noise detection component 5 is installed on the front wall of the lifting component 4; The opening and closing detection assembly 6 includes two mounting seats 61 arranged symmetrically on the left and right. Both mounting seats 61 are fixedly connected to the outer wall of the lifting assembly 4. The inner walls of the two mounting seats 61 are each mounted with a speed sensor 62. Both speed sensors 62 are used to measure the closing speed of the elevator car door during operation. A connecting block 63 is fixedly mounted on the rear wall of the lifting assembly 4, and a CCD detection camera 64 is mounted on the rear wall of the connecting block 63. The CCD detection camera 64 is used to detect the distance between the door gaps after the elevator car door is closed and whether the elevator car door is vertical; The noise detection component 5 includes a lifting frame 52, a mounting block 51 is fixedly installed at the bottom end of the lifting frame 52, the rear wall of the mounting block 51 is fixedly connected to the outer wall of the lifting component 4, and a receiving seat 53 is fixedly installed at the top end of the lifting frame 52, and a noise sensor 54 is installed on the top wall of the receiving seat 53.

[0029] The opening and closing detection component 6 and the noise detection component 5 are mainly driven by the lifting component 4 to work up and down, so that the operating status of different positions in the car can be detected. When the elevator is running and the car door is closing, the closing speeds of the car doors on both sides are detected to see if they are consistent. When the speed difference exceeds the design standard, the driving parts of the car door need to be repaired. After the car door is closed, the gap of the car door is detected to prevent the gap from being too large and causing safety risks. The verticality of the gap is also checked to see if it remains vertical after the car door is closed. The noise detection component 5 follows the lifting component 4 up and down, and monitors the noise decibels inside the car in real time. The detection of multiple operating states is conducive to providing data support for the accurate formulation of maintenance plans.

[0030] In this implementation, the noise, door closing gap, door verticality, and closing speed during elevator operation are detected in real time, which can provide clear data feedback on the elevator operation status and provide data support for subsequent elevator maintenance and safe operation.

[0031] Specifically, the two speed sensors 62 are matched with the corresponding elevator car door positions, the CCD detection camera 64 is matched with the closed door gap position of the elevator car door, and the CCD detection camera 64 and the speed sensor 62 are both electrically connected to the integrated controller 2.

[0032] When the elevator car door is opening and closing, its moving speed is captured in real time by the speed sensor 62. When data deviation occurs, the problem is discovered and solved in time. The CCD detection camera 64 and the speed sensor 62 are controlled by the integrated controller 2, and signals are transmitted to each other.

[0033] In this embodiment, the integrated controller 2 can control the entire electronic control component to work and transmit signals to each other to achieve the linkage use of the entire device.

[0034] Specifically, the lifting frame 52 is in the shape of "L", and the noise sensor 54 is electrically connected with the integrated controller 2. The noise sensor 54 is mainly used for detecting the noise decibel inside the elevator car during the operation of the elevator.

[0035] When the lifting frame 52 moves up and down, the noise sensor 54 moves synchronously, and the noise decibel generated by the elevator car during the operation of the elevator is monitored in real time. When noise abnormalities occur, problems can be found and solved quickly to prevent causing too much impact on the passenger's riding experience.

[0036] In the embodiment, under the work of the lifting assembly 4, the lifting frame 52 and the noise sensor 54 can be driven to move, and the decibel inside the car can be detected.

[0037] Specifically, the lifting assembly 4 includes a support 41, the bottom wall of the support 41 is fixedly connected with the top wall of the mounting frame 1, the mounting frame 1 is in the shape of a frame body, an adjusting lead screw one 42 is rotatably installed on the inner wall of the support 41, and the bottom end of the adjusting lead screw one 42 penetrates the support 41 and the mounting frame 1 through a bearing and is fixedly connected with the adjusting assembly 3.

[0038] In the embodiment, the support 41 is mainly used for accommodating the adjusting lead screw one 42, and the rotation adjustment of the adjusting lead screw one 42 is mainly driven by the adjusting assembly 3.

[0039] Specifically, the adjusting lead screw one 42 is externally screwed with a lifting block 44, the outer side walls of the lifting block 44 are fixedly connected with corresponding mounting seats 61, the rear wall of the lifting block 44 is fixedly connected with the front wall of a connecting block 63, and the front wall of the lifting block 44 is fixedly connected with the rear wall of a mounting block 51.

[0040] In the embodiment, when the adjusting lead screw one 42 rotates, the lifting block 44 moves linearly along the outer wall of the adjusting lead screw one 42, and the lifting block 44 moves up and down along the connecting block 63, the mounting seat 61 and the mounting block 51.

[0041] Specifically, the lifting block 44 slides in the inner wall of the support 41, a limiting rod 43 is fixedly installed on the inner top wall of the support 41, and the bottom end of the limiting rod 43 slides through the lifting block 44 and is fixedly connected with the inner bottom wall of the support 41.

[0042] In the embodiment, the lifting block 44 slides in the support 41 and slides along the outer wall of the limiting rod 43, so that the position deviation or overturning of the lifting block 44 is prevented, and the limiting rod 43 is mainly used for limiting the movement track of the lifting block 44.

[0043] Specifically, the adjustment assembly 3 includes several columns 31, and several columns 31 are evenly distributed on the bottom wall of the mounting frame 1. The top ends of several columns 31 are hingedly mounted to the bottom wall of the mounting frame 1 through a hinge seat, and the bottom ends of several columns 31 are fixedly mounted with columns 2 32. The bottom ends of several columns 2 32 are hingedly mounted with support seats 33 through a hinge seat, and the bottom walls of several support seats 33 are fixedly mounted with anti-slip pads 34.

[0044] In this embodiment, column 1 31 is hingedly mounted on the bottom wall of the mounting frame 1 and can rotate freely. At the same time, column 1 31 and column 2 32 drive the support seat 33 and the anti-slip pad 34 to contact the floor of the car, which has the effect of supporting and improving the stability of the entire device.

[0045] Specifically, vibration sensors 35 are fixedly installed on the outer walls of the support seats 33, and the vibration sensors 35 are electrically connected to the integrated controller 2. The vibration sensors 35 are mainly used to measure the vibration intensity of the elevator car during operation.

[0046] In this embodiment, the vibration sensor 35 installed on the outer side of the support base 33 is mainly used to detect the vibration intensity of the elevator car during operation.

[0047] Specifically, an adjusting screw rod 2 38 is rotatably installed on the bottom wall of the mounting frame 1, the top of the adjusting screw rod 2 38 is fixedly connected to the bottom end of the adjusting screw rod 1 42, a handle 39 is fixedly installed on the bottom end of the adjusting screw rod 2 38, a slide 37 is screwed on the outer wall of the adjusting screw rod 2 38, and support rods 36 are evenly hingedly installed on the outer wall of the slide 37, and the bottom ends of several support rods 36 are hingedly installed on the corresponding inner wall of the column 1 31.

[0048] In this embodiment, the handle 39 is used to drive the adjusting screw rod 2 38 to rotate, and then the adjusting screw rod 1 42 is driven to rotate synchronously, so that the adjusting component 3 can be driven to realize the open and close state, and at the same time the lifting component 4 is driven to work to drive the opening and closing detection component 6 and the noise detection component 5 to move in coordination. The whole device has strong linkage, and the operating status of the elevator car can be detected at different heights during the operation of the elevator. When the adjusting screw rod 2 38 rotates, it will drive the slide 37 to move linearly along the outer wall of the adjusting screw rod 2 38, and then drive the support rod 36 and the column 1 31 to contract and expand, so as to realize the height adjustment of the whole device.

[0049] Specifically, the horizontal detection component 7 includes a U-shaped frame 71, which is fixedly connected to the inner wall of the second column 32. A steering seat 74 is installed on the inner wall of the U-shaped frame 71 through a rotating shaft. A connecting rod 75 is fixedly installed on the bottom wall of the steering seat 74. A counterweight ball 76 is fixedly installed on the bottom end of the connecting rod 75. A limiting frame 72 is fixedly installed on the side wall of the second column 32 and located at the bottom of the U-shaped frame 71. A limiting groove 73 is provided on the top wall of the limiting frame 72. The steering seat 74 slides in the inner wall of the limiting groove 73. A sensor 77 is fixedly installed on the inner wall of the steering seat 74. An infrared measurement sensor 78 is fixedly installed on the side wall of the second column 32 and at the position corresponding to the sensor 77.

[0050] In this embodiment, after the expansion adjustment, the adjustment component 3 will drive the entire device to open, and then drive the horizontal detection component 7 to move synchronously. The setting of the horizontal detection component 7 is mainly used to monitor the horizontal state of the elevator during operation. When tilting occurs, the counterweight ball 76 will drive the connecting rod 75 and the steering seat 74 to rotate in the U-shaped frame 71 and the inner wall of the limit groove 73, so that the distance between the sensor 77 and the infrared measurement sensor 78 changes, and then the horizontal state of the elevator car can be measured when the elevator is in operation.

[0051] The working principle of this device is as follows: before operation, the entire device is first placed inside the elevator car, and the vibration sensor 35, noise sensor 54, speed sensor 62, CCD detection camera 64, sensor 77 and infrared measurement sensor 78 are electrically connected through the external power supply, external controller and integrated controller 2, and the signal transmission is kept normal. At the same time, the measured elevator design standards (including vibration amplitude, noise, door closing gap and closing speed) are transmitted to the controller as the detection standard. Any abnormal detection data during the detection process can be quickly known; The entire device is placed at the inner center of the car, and then the adjustment handle 39 is started to drive the adjusting screw rod 2 38 to rotate, so that the slide 37 drives the support rod 36 to move linearly downward along the outer wall of the adjusting screw rod 2 38. When the support rod 36 gradually moves downward, it will drive the column 1 31 and the column 2 32 to open outward, and the column 1 31 gradually rotates outward on the bottom wall of the mounting frame 1. When the column 2 32 expands outward, it drives the support seat 33, the anti-skid pad 34, the vibration sensor 35 and the horizontal detection component 7 to move outward. When the expansion angle of the column 1 31 is adjusted, the support seat 33 and the anti-skid pad 34 are in contact with the ground inside the car. The setting of the anti-skid pad 34 can increase the friction with the inside of the car, prevent the entire device from sliding, and improve the support stability. At the same time, the vibration sensor 35 monitors the vibration amplitude of the elevator in real time during operation. When the whole adjustment of the adjusting assembly 3 is completed, the CCD detection camera 64 is kept consistent with the center line of the closing of the car door, and the adjusting screw rod two 38 drives the adjusting screw rod one 42 to rotate when rotating, the number of threads on the adjusting screw rod two 38 is four times the number of threads on the adjusting screw rod one 42, the length of the adjusting screw rod two 38 is twice the length of the adjusting screw rod one 42, and the screw directions of the adjusting screw rod two 38 and the adjusting screw rod one 42 are opposite, the adjusting screw rod one 42 drives the lifting block 44 to move linearly in the inner wall of the support 41 along the outer wall of the adjusting screw rod one 42 and the limiting rod 43 when rotating, and then the lifting block 44 drives the connecting block 63 and the CCD detection camera 64 to move when moving, the CCD detection camera 64 is kept in a matching state with the center line of the closing of the car door, and the gap of the closing of the car door and the overall vertical state after the closing of the car door are detected by the CCD detection camera 64; When the lifting block 44 moves, the mounting block 51 and the lifting frame 52 are driven to move, the lifting frame 52 drives the receiving seat 53 and the noise sensor 54 to rise, and the noise in the car during the operation of the elevator is monitored in real time by the noise sensor 54; When the whole device is debugged, the elevator is started in the car, the closing speed of the car door is monitored in real time by the speed sensor 62 when the car door is closing, and whether the gap of the closing of the car door and the car door is in a vertical state is detected by the CCD detection camera 64 after the closing is completed, so as to obtain whether the car door in the car is inclined, the detected real-time data is transmitted to the integrated controller 2, the detected real-time data is compared with the design standard by the integrated controller 2, and more accurate operation state data can be obtained; When the car is running in the elevator, the vibration of the car during the operation is monitored in real time by the vibration sensor 35, the noise decibel in the car during the operation of the elevator is sensed in real time by the noise sensor 54, and then the detected real-time data is transmitted to the integrated controller 2, and the detected real-time data is compared with the design standard by the integrated controller 2; When the adjusting assembly 3 is adjusted, the lifting assembly 4, the noise detection assembly 5, and the opening and closing detection assembly 6 can also be driven to move synchronously, the positions of the CCD detection camera 64, the noise sensor 54, the speed sensor 62, and the vibration sensor 35 can be adjusted, and then the data comparison of multi-position testing is performed, so that the accuracy of the whole operation state monitoring process is higher; When the elevator is in operation, the entire device is in a stable state due to the stable support of the adjustment component 3. After the column 1 31 drives the column 2 32 to expand and open, the counterweight ball 76 drives the connecting rod 75 and the steering seat 74 to rotate in the limit groove 73 on the limit frame U-shaped frame 71 and the inner wall of the U-shaped frame 71. When the position adjustment of the column 1 31 and the column 2 32 is completed, the counterweight ball 76 drives the connecting rod 75 and the steering seat 74 to be in a vertical state with the elevator car, and the distance between them and the sensor 77 is measured by the infrared measurement sensor 78. When the elevator is tilted during lifting, the counterweight ball 76 drives the connecting rod 75 and the steering seat 74 to rotate in the inner wall of the U-shaped frame 71, and the steering seat 74 moves in the inner wall of the limit groove 73 on 72. At this time, the distance between the infrared measurement sensor 78 and the sensor 77 changes. When the elevator tilts left to right (left to right), the distance between the left infrared measurement sensor 78 and the sensor 77 increases, and the distance between the right infrared measurement sensor 78 and the sensor 77 decreases. Conversely (right to left), the distance between the left infrared measurement sensor 78 and the sensor 77 decreases, and the distance between the right infrared measurement sensor 78 and the sensor 77 increases. When the elevator tilts forward and backward (front to back), the distance between the front infrared measurement sensor 78 and the sensor 77 increases, and the distance between the rear infrared measurement sensor 78 and the sensor 77 decreases. Conversely (back to front), the distance between the front infrared measurement sensor 78 and the sensor 77 decreases, and the distance between the rear infrared measurement sensor 78 and the sensor 77 increases. By the elevator's lifting and lowering operation, it is possible to detect whether the elevator car has a tilt problem during lifting and lowering.

[0052] The entire device can conduct real-time detection of the vibration amplitude, noise, door closing gap and verticality, closing speed, and whether there is any tilting during the operation of the elevator. After comparing the detection data with the design standards, it has a more accurate technical solution for the maintenance of the elevator, and provides strong data and technical support for the safe operation of the elevator.

[0053] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
