Description

Technical Field

[0001] The invention belongs to the technical field of elevator guide rail detection, and in particular relates to a synchronous verticality detection device and a detection method for an elevator guide rail. Background Art

[0002] Elevator guide rails will deform and displace during the manufacturing, installation and use processes, resulting in guide rail verticality errors and guide rail top surface spacing deviations, which will harm the safe use of the elevator and affect the service life of the elevator. Therefore, guide rail installation quality measurement is particularly important for elevator operation safety.

[0003] The existing elevator guide rail verticality measuring device can only measure the verticality of one set of guide rails at a time, and elevator guide rails are usually provided with two sets. Therefore, the device often needs to be repeatedly installed and calibrated to complete the verticality measurement of the two sets of guide rails. The operation is relatively cumbersome and greatly increases the workload of workers.

[0004] After searching, in the prior art, the announcement number: CN216206201U, the announcement number: 2022-04-05, discloses an elevator guide rail verticality detection tooling, and in view of the problem of large verticality detection error of the elevator guide rail, the following technical solution is provided, including a second slider slidably connected to the guide rail, a first slider detachably connected to the second slider, and a traction assembly for driving the first slider to slide along the guide rail, the traction assembly is arranged in the hoistway; a pressure sensor is arranged between the first slider and the second slider to measure the pressure between the first slider and the second slider; a vertical guide assembly is arranged in the hoistway, and the vertical guide assembly is used to support the first slider to slide along the direction of gravity and press the first slider toward the second slider. The vertical guide assembly guides the first slider in the direction of gravity and presses the first slider toward the second slider, the traction assembly drives the first slider and the second slider to slide on the guide rail, the pressure sensor measures the pressure between the first slider and the second slider, and the verticality error of the guide rail is inferred according to the change value of the pressure sensor.

[0005] However, the device still has the following defects: although the verticality error of the guide rail can be inferred from the change value of the pressure sensor, the verticality detection tool can only measure the verticality of one set of guide rails at a time, so the device needs to be repeatedly installed and calibrated to complete the verticality measurement of two sets of guide rails.

[0030] For example, Figure 6 shown.

[0031] A transmission slot 5081 is provided at the inner center of the calibration box 508. Two groups of adjustment mechanisms 5084 are arranged in the calibration box 508. The adjustment mechanisms 5084 include a second motor 50841. The two groups of the second motors 50841 are electrically connected to a corresponding group of control buttons 5024, respectively.

The threaded rod 50842 is threadedly connected to an inner A threaded barrel 50843, one end of the internally threaded barrel 50843 penetrates through the outer wall of the calibration box 508 and is fixedly connected to a set of limiting mechanisms 509, two sets of limiting blocks 50844 are arranged on the internally threaded barrel 50843, two sets of slide grooves 5082 are symmetrically opened in the calibration box 508, the two sets of slide grooves 5082 are movably fitted with the two sets of internally threaded barrels 50843 respectively, two sets of limiting grooves 5083 are symmetrically opened in the calibration box 508, the two sets of limiting grooves 5083 are movably fitted with the two sets of limiting blocks 50844 respectively; Specifically, the threaded rod 50842 is driven to rotate by the second motor 50841, so that the internal threaded tube 50843 drives the corresponding set of limiting mechanisms 509 to move horizontally, and the limiting mechanisms 509 are extended to a position that fits the inner wall of the elevator shaft, thereby limiting the vertical position of the calibration box 508 to prevent the calibration box 508 from shifting during the up and down movement. The positions of the two sets of limiting mechanisms 509 are adjusted respectively by two sets of second motors 50841, so that the infrared light spot emitted by the infrared transmitter 506 coincides with the center mark 5022, so that the calibration box 508 is always located at the center between the first guide rail 2 and the second guide rail 3 during the movement, so as to facilitate the synchronous verticality detection of the first guide rail 2 and the second guide rail 3.

[0032] The limiting mechanism 509 includes a U-shaped block 5091; illustratively, as Figure 7 and Figure 8 shown.

[0033] One side wall of the U-shaped block 5091 is fixedly connected to one end of a corresponding group of internal threaded cylinders 50843, an extrusion roller 5092 is arranged between the inner walls on both sides of the U-shaped block 5091, and the extrusion roller 5092 is movably fitted with a corresponding group of guide rails, and linkage blocks 5093 are arranged on the outer walls on both sides of the U-shaped block 5091, and linkage shafts 5098 are rotatably connected to the two groups of linkage blocks 5093, and the two groups of linkage shafts 5098 are respectively fixedly connected to the two ends of the extrusion roller 5092, and the two side walls of the U-shaped block 5091 are provided with through grooves 50911, and the two groups of through grooves 50911 are respectively movably fitted with the two groups of linkage shafts 5098, and a plurality of groups of mounting grooves 50912 are arranged on the U-shaped block 5091, and the plurality of groups of mounting grooves 50912 are The U-shaped block 5091 is rotatably connected with a roller 50913, and several groups of the rollers 50913 are movably fitted with the inner wall of the elevator shaft. The side wall of the U-shaped block 5091 is fixedly connected with two groups of extension plates 5094, and the two groups of extension plates 5094 are installed with pressure sensors 5095. The two groups of pressure sensors 5095 are electrically connected to the controller. The two groups of pressure sensors 5095 are fixedly connected with a telescopic rod 5096, and the other end of the telescopic rod 5096 is fixedly connected with a collar 5097, and the collar 5097 is sleeved on the linkage block 5093. The telescopic rod 5096 is sleeved with a spring 5099, and one end of the spring 5099 is fixedly connected to the collar 5097, and the other end of the spring 5099 is fixedly connected to the pressure sensor 5095; Specifically, by making the two calibrated groups of U-shaped blocks 5091 respectively fit with the inner walls on both sides of the elevator shaft, the rollers 50913 on the U-shaped blocks 5091 fit with the inner walls on both sides of the elevator shaft, the vertical direction of the detection component 5 is limited, and the detection component 5 is moved up and down more smoothly through the rollers 50913; Furthermore, through the tension of the spring 5099, the telescopic rod 5096 drives the squeezing roller 5092 to fit against the side wall of the corresponding set of guide rails. When the detection box 502 drives the limit mechanism 509 to move up and down, the U-shaped block 5091 fits against the side wall of the elevator shaft, and its vertical position does not change. The squeezing roller 5092 fits against the side wall of the guide rail. When the first guide rail 2 or the second guide rail 3 tilts in the vertical direction, the length of the telescopic rod 5096 changes, thereby changing the squeezing force of the spring 5099 on the pressure sensor 5095. The pressure value is detected by the pressure sensor 5095 and the data is transmitted to the controller. The inclination angle value of the guide rail can be calculated according to the change of the pressure value, thereby realizing the verticality detection of the guide rail.

[0034] The synchronous verticality detection device for elevator guide rails proposed by the present invention has the following working principle: The traction mechanism 1 is installed to the inner wall of the elevator shaft and close to the top position, and is fixed. One end of the traction rope 4 is wrapped around the traction mechanism 1. After one end of the traction rope 4 passes through the limiting ring 107, the traction rope 4 is fit into the guide groove 1041, and the other end of the traction rope 4 is connected to the detection component 5, so that the vertical position of the detection component 5 remains unchanged during the up and down movement.

[0035] The threaded rod 50842 is driven to rotate by the second motor 50841, so that the internal threaded tube 50843 drives the corresponding set of limit mechanisms 509 to move horizontally, and the limit mechanisms 509 are extended to a position that fits the inner wall of the elevator shaft, thereby limiting the vertical position of the calibration box 508 to prevent the calibration box 508 from shifting during the up and down movement. The positions of the two sets of limit mechanisms 509 are adjusted respectively by two sets of second motors 50841, so that the infrared light spot emitted by the infrared transmitter 506 coincides with the center mark 5022, so that the calibration box 508 is always located at the center between the first guide rail 2 and the second guide rail 3 during the movement, so as to facilitate the synchronous verticality detection of the first guide rail 2 and the second guide rail 3.

[0036] The first motor 108 drives the worm 109 to rotate, so that the worm wheel 1010 drives the pay-off roller 103 to rotate synchronously, thereby realizing the retracting and releasing operation of the traction rope 4, thereby realizing the height adjustment of the detection component 5, and the self-locking performance between the worm wheel 1010 and the worm 109 effectively improves the stability of the detection component 5 during the up and down movement.

[0037] By making the two calibrated groups of U-shaped blocks 5091 fit against the inner walls on both sides of the elevator shaft respectively, the rollers 50913 on the U-shaped blocks 5091 fit against the inner walls on both sides of the elevator shaft, the vertical direction of the detection component 5 is limited, and the rollers 50913 make the detection component 5 move up and down more smoothly.

[0038] Through the tension of the spring 5099, the telescopic rod 5096 drives the squeezing roller 5092 to fit against the side wall of the corresponding set of guide rails. When the detection box 502 drives the limit mechanism 509 to move up and down, the U-shaped block 5091 fits against the side wall of the elevator shaft, and its vertical position does not change. The squeezing roller 5092 fits against the side wall of the guide rail. When the first guide rail 2 or the second guide rail 3 tilts in the vertical direction, the length of the telescopic rod 5096 changes, thereby changing the squeezing force of the spring 5099 on the pressure sensor 5095. The pressure value is detected by the pressure sensor 5095 and the data is transmitted to the controller. The inclination angle value of the guide rail can be calculated according to the change of the pressure value, thereby realizing the verticality detection of the guide rail.

[0039] The height of the detection box 502 is detected by a laser rangefinder 507, and the height data is fed back to the controller and displayed on a display screen 5023 to record and analyze the verticality detection data corresponding to the guide rails at different heights, so that the user can adjust the verticality of the guide rails at different heights according to the detection data.

[0040] Based on the above-mentioned synchronous verticality detection device for elevator guide rails, an embodiment of the present invention further proposes a detection method for the verticality detection device. Exemplarily, the detection method includes: Install the traction mechanism to the center axis of the inner wall of the elevator shaft and close to the top, and fix it; Wrap one end of the traction rope around the pay-off roller, pass one end of the traction rope through the limiting ring, fit the traction rope into the guide groove, and connect the other end of the traction rope to the detection component; The two sets of second motors are respectively controlled to start by the control buttons, and the positions of the two sets of limit mechanisms are respectively adjusted until the two sets of limit mechanisms are respectively fitted with the two sets of inner walls of the elevator shaft; Control the two sets of second motors to rotate forward and reverse to fine-tune the positions of the two sets of limit mechanisms until the infrared light spot emitted by the infrared transmitter coincides with the center mark, thus completing the calibration of the position of the detection component; Turn on the first motor to drive the worm to rotate, so that the worm wheel drives the pay-off roller to rotate synchronously, and the traction rope drives the detection assembly to move downward; The pressure sensor detects the pressure value and transmits the data to the controller. The inclination angle value of the first guide rail and the second guide rail can be calculated through the change of the pressure value, thereby realizing the verticality detection of the first guide rail and the second guide rail.

[0041] The laser rangefinder detects the height of the detection box and feeds the height data back to the controller, which is displayed on the display screen to record and analyze the verticality detection data corresponding to the guide rails at different heights, so that the user can adjust the verticality of the guide rails at different heights according to the detection data.
