Description

Technical Field

[0001] This invention relates to the field of clothes drying rack testing technology, specifically to a ceiling-mounted clothes drying rack testing device and a testing method using the same. Background Technology

[0002] Ceiling-mounted clothes drying racks require performance tests before leaving the factory, including electrical, mechanical transmission, and safety tests. Existing performance testing equipment for ceiling-mounted clothes drying racks requires at least two operators to move the rack onto the equipment. During testing, manual handling of loads weighing tens of kilograms (such as sandbags) is also necessary for counterweight testing, increasing labor intensity and extending testing time. Furthermore, existing testing equipment suffers from inaccuracies in testing the clothes drying rack's wire ropes, the wire ropes being tested in ways that significantly deviate from actual operating conditions, and poor stability of the wire ropes under load. During testing with existing equipment, inaccurate length measurements of the wire ropes can occur due to the swaying of the loads and uneven stress on the two wire ropes connecting the drying racks during testing. Summary of the Invention

[0003] In view of this, it is necessary to propose a testing device for ceiling-mounted clothes drying racks and a testing method thereof to address the above-mentioned problems, so as to overcome some of the shortcomings of the above-mentioned background technology and solve the following technical problem: how to accurately, efficiently and labor-savingly conduct standard stability tests on the steel wire ropes used to connect the drying rods of ceiling-mounted clothes drying racks under load.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention proposes a testing device for a ceiling-mounted clothes drying rack. The clothes drying rack includes a body, a wire rope unwinding mechanism disposed within the body, a first wire rope for connecting one end of the clothes drying rack's drying rod, and a second wire rope for connecting the other end of the clothes drying rack's drying rod. The testing device for the ceiling-mounted clothes drying rack includes:

[0006] A frame, wherein the frame is provided with a test station, the test station being used to fix the machine body during testing;

[0007] The left test rope, used as a test rope to provide vertical upward tension to the first drying pole wire rope, extends vertically downward after being bent by a first pulley mechanism;

[0008] The right test rope, used as a test rope to provide vertical upward tension to the steel wire rope of the second drying pole, extends vertically downward after being bent by a second pulley mechanism.

[0009] The crossbar is detachably connected to the lead-out ends of the first and second drying pole wire ropes during testing; the two ends of the crossbar are also fixedly connected to one end of the left and one end of the right test pull rope, respectively.

[0010] The pre-mounted components are fixedly connected to the other end of the left test rope that extends vertically downward after being bent and the other end of the right test rope that extends vertically downward after being bent, so as to provide a vertically upward pulling force to the crossbar by its own weight.

[0011] The weighted mounting device is used to apply a load to the pre-mounted device during testing.

[0012] The lifting assembly is used to lift and support the weighted mounting device. When the lifting assembly lowers the weighted mounting device and does not apply force to the weighted mounting device, the weighted mounting device and the pre-mounted device together provide a vertical upward pulling force to both ends of the crossbar.

[0013] Furthermore, the pre-mount device includes a left pre-mount device and a right pre-mount device; the weight-bearing device includes a left weight-bearing device and a right weight-bearing device;

[0014] The left pre-mounted component is fixedly connected to the other end of the left test rope, which extends vertically downwards after being bent. The left pre-mounted component, through its own weight and in conjunction with the weight of the right pre-mounted component, provides a vertically upward pulling force to the crossbar. The left weight-bearing component is used to apply a load to the left pre-mounted component during testing. The right pre-mounted component is fixedly connected to the other end of the right test rope, which extends vertically downwards after being bent. The right pre-mounted component, through its own weight and in conjunction with the weight of the left pre-mounted component... Gravity provides a vertically upward pulling force to the crossbar; the right weighted mount is used to apply a load to the right pre-mount during testing; the lifting assembly is used to lift and raise the left and right weighted mounts; when the lifting assembly lowers the left and right weighted mounts and the lifting assembly does not apply force to the left and right weighted mounts, the left pre-mount, right pre-mount, left weighted mount, and right weighted mount together provide a vertically upward pulling force to both ends of the crossbar.

[0015] Furthermore, the ceiling clothes drying rack testing equipment also includes a rope identification sensor assembly, installed on the frame, used to identify the size and condition of the first and second drying rod wire ropes during testing.

[0016] Furthermore, the left heavy-duty mounting component has a first cable pass through its top and bottom surfaces, through which the left test cable passes; the right heavy-duty mounting component has a second cable pass through its top and bottom surfaces, through which the right test cable passes.

[0017] Furthermore, the frame is also equipped with an obstruction limiting mechanism; the obstruction limiting mechanism serves as the upper limit position of the horizontal bar's upward stroke.

[0018] Furthermore, the lifting assembly includes a left lifting device with a left lifting arm and a right lifting device with a right lifting arm; the left lifting arm is used to vertically lift the left heavy load component; when the left lifting arm leaves the left heavy load component, the left lifting arm does not contact the left pre-load component, and the weight of the left heavy load component is applied to the left pre-load component.

[0019] The right lifting arm is used to vertically lift the right heavy-duty mounting component; when the right lifting arm leaves the right heavy-duty mounting component, the right lifting arm does not contact the right pre-mounted component, and the weight of the right heavy-duty mounting component is applied to the right pre-mounted component.

[0020] Furthermore, the ceiling-mounted clothes drying rack testing equipment also includes a controller; the pull rope identification sensor assembly includes a first laser rangefinder and a second laser rangefinder; the controller is communicatively connected to both the first and second laser rangefinders; both the first and second laser rangefinders are mounted on the frame, and the mounting positions of the first and second laser rangefinders are at the same horizontal line; the first laser detection point of the first laser rangefinder is located at a first structural position at the same height as the end of the first drying rod wire rope hanging on the crossbar, and the first laser rangefinder is used to detect the distance between the first laser detection point and its fixed reference point; the second laser detection point of the second laser rangefinder is located at a second structural position at the same height as the end of the second drying rod wire rope hanging on the crossbar, and the second laser rangefinder is used to detect the distance between the first laser detection point and its fixed reference point.

[0021] Furthermore, the ceiling-mounted clothes drying rack testing equipment also includes a limit detection sensor assembly; the controller is electrically connected to the limit detection sensor assembly; the limit detection sensor assembly is installed on the frame and is used to detect the position of the crossbar;

[0022] The limit detection sensor assembly includes a first photoelectric detection switch, a second photoelectric detection switch, and a third photoelectric detection switch. All three switches are mounted on a frame, with the first switch vertically higher than the second switch, and the second switch vertically higher than the third switch. The third switch detects the lowering limit of the crossbar's lifting stroke. The second switch detects the crossbar reaching a condition-triggered position during the lifting process. When the crossbar passes this condition-triggered position and the simulated clothes drying rack is lightly lowered, the lifting assembly supporting the left and right pre-loaded components begins to move closer to them. The first switch also acts as a detection switch to stop the crossbar from lifting when the first and second laser rangefinders detect the length of the wire rope.

[0023] This invention further proposes a testing method using any of the above-described ceiling-mounted clothes drying rack testing equipment, comprising the following steps performed in sequence:

[0024] Step 1: Detachably connect the lead-out ends of the first and second wire ropes of the drying pole to the two ends of the crossbar.

[0025] Step 2: By controlling the unwinding mechanism of the clothes drying rack's wire rope, the crossbar is reset to the starting position of the lightly loaded crossbar during its lifting stroke;

[0026] Step 3: Conduct a test simulating the light-load descent of the clothes drying rack's rod: By controlling the clothes drying rack's wire rope unwinding mechanism, the crossbar is raised from the starting position of the light-load crossbar to the ending position of the light-load crossbar's lifting stroke under the gravity pull of the pre-loaded device.

[0027] Step 4: Control the unwinding mechanism of the clothes drying rack's wire rope to lower and reset the crossbar to the starting position of the lightly loaded crossbar.

[0028] Step 5: By controlling the lifting assembly, the weighted mounting device applies a load to the pre-mounted device and then the weighted mounting device detaches from the lifting assembly.

[0029] Step 6: Conduct a test simulating the heavy load lifting of the clothes drying rack rod of the ceiling-mounted clothes drying machine: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar overcomes the weight of the weight-bearing device and the pre-loaded device, and then descends from the starting position of the heavy load crossbar descent to the ending position of the heavy load crossbar descent during the lifting stroke.

[0030] Step 7: Lift the weighted mounting device by controlling the lifting assembly to detach the weighted mounting device from the pre-mounted device;

[0031] Step 8: When the crossbar moves to a standard height position of the lifting stroke, measure whether the lengths of the first and second drying pole wire ropes are qualified.

[0032] This invention further proposes a testing method using the ceiling-mounted clothes drying rack testing equipment described above, comprising the following steps performed in sequence:

[0033] Step S1: Detachably connect the lead-out ends of the first and second drying pole wire ropes to the two ends of the crossbar.

[0034] Step S2: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar is reset to the starting position of the light-load crossbar rising during the lifting stroke;

[0035] Step S3, conduct a test simulating the light-load descent of the clothes drying rack rod: by controlling the unwinding mechanism of the clothes drying rack wire rope, the crossbar is raised from the starting position of the light-load crossbar to the ending position of the light-load crossbar rising stroke under the gravity pull of the left pre-load and right pre-load parts.

[0036] Step S4: Control the unwinding mechanism of the clothes drying machine's wire rope to lower and reset the crossbar to the starting position of the light-load crossbar's ascent;

[0037] Step S5: By controlling the lifting assembly, the left heavy-load mounting piece presses down on the left pre-mounted piece under load, and then the left heavy-load mounting piece disengages from the lifting assembly. The right heavy-load mounting piece presses down on the right pre-mounted piece under load, and then the right heavy-load mounting piece disengages from the lifting assembly.

[0038] Step S6: Conduct a test simulating the heavy load rise of the clothes drying rack in the ceiling: By controlling the unwinding mechanism of the clothes drying rack wire rope, the crossbar overcomes the gravity of the left pre-loaded component, the right pre-loaded component, the left heavy loaded component and the right heavy loaded component, and then descends from the starting position of the heavy load crossbar descent to the ending position of the heavy load crossbar descent in the lifting stroke.

[0039] Step S7: By controlling the lifting assembly, the left heavy-duty mounting component is lifted to disengage from the left pre-mounted component, and the right heavy-duty mounting component is lifted to disengage from the right pre-mounted component.

[0040] Step S8: When the crossbar moves to a standard height position of the lifting stroke, check whether the lengths of the first and second drying pole wire ropes are qualified: compare and analyze the detection distance information obtained by the first and second laser rangefinders with several standard data to obtain the detection results of whether the lengths of the first and second drying pole wire ropes are qualified.

[0041] The beneficial effects of this invention are as follows:

[0042] This invention enables precise, efficient, and labor-saving standard stability testing of the steel wire ropes used to connect the drying rods of ceiling-mounted clothes drying racks under load. It greatly improves the testing efficiency of ceiling-mounted clothes drying racks, obtains test results accurately and quickly, and reduces the risk of manual input or operational errors during the testing process. It also reduces detection errors caused by factors such as unbalanced force on the two steel wire ropes, steel wire rope swaying or transmission interference, and vibration of the installed counterweight components. It more realistically simulates the actual working conditions of the clothes drying rack when the drying rods are raised and lowered, thus more accurately detecting faults in the steel wire ropes and their unwinding.

[0051] Example 1

[0052] like Figure 1 As shown:

[0053] This embodiment proposes a testing device for a ceiling-mounted clothes drying rack. The clothes drying rack includes a body 400, a wire rope unwinding mechanism disposed in the body 400, a first wire rope 200 for connecting one end of the clothes drying rack's drying rod, and a second wire rope 300 for connecting the other end of the clothes drying rack's drying rod. The testing device for the ceiling-mounted clothes drying rack includes:

[0054] The frame 1 is provided with a test station, which is used to fix the machine body 400 during testing;

[0055] Left test pull rope 2, as a test pull rope that provides vertical upward tension to the first drying pole wire rope 200, extends vertically downward after being bent by a first pulley mechanism;

[0056] The right test rope 3, used as a test rope to provide vertical upward tension to the second drying pole wire rope 300, extends vertically downward after being bent by a second pulley mechanism.

[0057] The two ends of the crossbar 4 are detachably connected to the end of the first drying rod wire rope 200 and the end of the second drying rod wire rope 300 during the test; the two ends of the crossbar 4 are also fixedly connected to one end of the left test pull rope 2 and one end of the right test pull rope 3.

[0058] Pre-mounted component device ( Figure 1 (Not shown), both are fixedly connected to the other end of the left test rope 2 that extends vertically downward after being bent and the other end of the right test rope 3 that extends vertically downward after being bent, so as to provide a vertically upward pulling force to the crossbar 4 by its own weight;

[0059] Weighted mounting device ( Figure 1 (Not shown), used to apply a load to the pre-mounted device during testing;

[0060] The lifting assembly 9 is used to lift and support the weighted mounting device. When the lifting assembly 9 lowers the weighted mounting device and does not apply force to the weighted mounting device, the weighted mounting device and the pre-mounted device together provide a vertical upward pulling force to both ends of the crossbar 4.

[0061] The ceiling-mounted clothes drying rack testing equipment of this embodiment can accurately, efficiently, and labor-savingly perform standard stability tests on the steel wire ropes used to connect the drying rods of the ceiling-mounted clothes drying rack under load, thereby greatly improving the testing efficiency of the ceiling-mounted clothes drying rack. It can obtain test results accurately and quickly, reduce the risk of manual input or operational errors in the clothes drying rack testing process, and reduce the detection errors caused by factors such as unbalanced force on the two steel wire ropes of the clothes drying rack, steel wire rope swaying or transmission interference, and vibration of the installed counterweight components. It more realistically simulates the actual working conditions when the clothes drying rack is raised and lowered, thereby more accurately detecting the faults of the clothes drying rack steel wire ropes and their unwinding.

[0062] Ideally, the pre-mounted component device includes a left pre-mounted component 5 and a right pre-mounted component 7; the weighted component device includes a left weighted component 6 and a right weighted component 8.

[0063] The left pre-mounted component 5 is fixedly connected to the other end of the left test rope 2, which extends vertically downward after being bent; the left pre-mounted component 5 is used to provide a vertically upward pulling force to the crossbar 4 by its own weight in conjunction with the weight of the right pre-mounted component 7; the left weight-bearing component 6 is used to apply a load to the left pre-mounted component 5 during testing; the right pre-mounted component 7 is fixedly connected to the other end of the right test rope 3, which extends vertically downward after being bent; the right pre-mounted component 7 is used to provide a vertically upward pulling force to the crossbar 4 by its own weight in conjunction with the weight of the left pre-mounted component 5; the right weight-bearing component 8 is used to apply a load to the right pre-mounted component 7 during testing; the lifting assembly 9 is used to lift and support the left weight-bearing component 6 and the right weight-bearing component 8; when lifting... When component 9 lowers the left and right weighted hanging parts 6 and 8, and the lifting component 9 does not apply force to the left and right weighted hanging parts 6 and 8, the left pre-hanging part 5, the right pre-hanging part 7, the left weighted hanging part 6, and the right weighted hanging part 8 together provide a vertical upward pulling force to both ends of the crossbar 4. This makes the test conditions closer to an actual working condition, realistically simulating the actual working conditions when the clothes drying rack is raised and lowered, and more realistically simulating the heavy or light load hanging state of the clothes drying rack. It avoids changing the steel wire rope from vertical to horizontal arrangement through pulleys, or from longitudinal to horizontal arrangement through pulleys, reducing the relevant transmission friction and reducing the number of unnecessary pulleys, thereby making the test more accurate.

[0064] Optimized, the ceiling-mounted clothes drying rack testing equipment also includes a rope identification sensor assembly 10, installed on the frame 1, used to identify the dimensional status of the first drying rod wire rope 200 and the second drying rod wire rope 300 during testing; the rope identification sensor assembly 10 can accurately and efficiently detect the dimensional status of the wire rope, and accurately and quickly obtain test data, wire rope deformation and length results; the dimensional status reflects the length status of the wire rope, or reflects the length status and deformation status of the wire rope.

[0065] Optimally, the left weight-bearing bracket 6 has a first cable passage 61 extending through its top and bottom surfaces, through which the left test pull rope 2 passes. This reduces friction between the left weight-bearing bracket 6 and the left test pull rope 2, and also prevents the left test pull rope from swaying due to the raising and lowering of the left weight-bearing bracket 6. The right weight-bearing bracket 8 has a second cable passage 81 extending through its top and bottom surfaces, through which the right test pull rope 3 passes. This reduces friction between the right weight-bearing bracket 8 and the right test pull rope 3, and also prevents the right test pull rope 3 from swaying due to the raising and lowering of the right weight-bearing bracket 8.

[0066] Optimally, the lifting assembly 9 includes a left lifting device 91 with a left lifting arm 911 and a right lifting device 92 with a right lifting arm 921; the left lifting arm 911 is used to vertically lift the left weighted load 6; when the left lifting arm 911 leaves the left weighted load 6, the left lifting arm 911 does not contact the left pre-loaded load 5, and the weight of the left weighted load 6 is applied to the left pre-loaded load 5; in this way, the left lifting arm 911 can smoothly place the left weighted load 6 on the left pre-loaded load 5, and will not cause the left test pull rope 2 to shake, thus keeping the left test pull rope 2 under accurate force.

[0067] The right lifting arm 921 is used to vertically lift the right weighted mounting component 8. When the right lifting arm 921 leaves the right weighted mounting component 8, the right lifting arm 921 does not contact the right pre-mounted component 7, and the weight of the right weighted mounting component 8 is applied to the right pre-mounted component 7. In this way, the right weighted mounting component 8 can stably place the right weighted mounting component 8 on the right pre-mounted component 7 without causing the right test pull rope 3 to shake, thus maintaining the accurate force on the right test pull rope 3.

[0068] Optimized, the ceiling-mounted clothes drying rack testing equipment also includes a controller 12; the pull rope identification sensor assembly 10 includes a first laser rangefinder 101 and a second laser rangefinder 102; the controller 12 is communicatively connected to the first laser rangefinder 101 and the second laser rangefinder 102 respectively; both the first laser rangefinder 101 and the second laser rangefinder 102 are mounted on the frame 1, and the mounting positions of the first laser rangefinder 101 and the second laser rangefinder 102 are on the same horizontal line; the first laser detection point of the first laser rangefinder 101 is located at a first structural position at the same height as the end of the first drying rod wire rope 200 hanging on the crossbar 4. The first laser rangefinder 101 is used to detect the distance between the first laser detection point and the fixed reference point of the first laser rangefinder 101; the second laser detection point of the second laser rangefinder 102 is located at a second structural position at the same height as the end of the wire rope 300 of the second drying pole hanging on the crossbar 4, and the second laser rangefinder 102 is used to detect the distance between the second laser detection point and the fixed reference point of the second laser rangefinder 102; the first laser rangefinder 101 and the second laser rangefinder 102 can simultaneously and accurately and efficiently detect the length status of the first drying pole wire rope 200 and the second drying pole wire rope 300, and accurately and quickly obtain test data, wire rope deformation and length dimension results.

[0069] Optimized, the ceiling clothes drying rack testing equipment also includes a limit detection sensor assembly 11; the controller 12 is electrically connected to the limit detection sensor assembly 11; the limit detection sensor assembly 11 is installed on the frame 1, and the limit detection sensor assembly 11 is used to detect the position of the crossbar 4;

[0070] The limit detection sensor assembly 11 includes a first photoelectric detection switch 111, a second photoelectric detection switch 112, and a third photoelectric detection switch 113. All three switches are mounted on the frame 1. The first photoelectric detection switch 111 is vertically higher than the second photoelectric detection switch 112, and the second photoelectric detection switch 112 is vertically higher than the third photoelectric detection switch 113. The third photoelectric detection switch 113 is used to detect the lowering limit of the crossbar 4's lifting stroke, preventing interference caused by the crossbar 4 exceeding its travel. The second photoelectric detection switch 112 is used to detect when the crossbar 4 reaches a condition-triggered position during the lifting process. When the device is triggered and the clothes drying rack of the ceiling-mounted clothes drying rack is lowered under light load, the lifting assembly 9 that supports the left heavy-duty hanging component 6 and the right heavy-duty hanging component 8 begins to move closer to the left pre-hanging component 5 and the right pre-hanging component 7. The first photoelectric detection switch 111 acts as a detection switch to stop the lifting of the crossbar 4 when the first laser ranging sensor 101 and the second laser ranging sensor 102 detect the length of the wire rope. This enables the crossbar 4 to automatically detect the length of the wire rope when it is in the optimal position through the first laser ranging sensor 101 and the second laser ranging sensor 102. This prepares for loading the heavy-duty hanging components, that is, shortens the time for the left heavy-duty hanging component 6 to move to the left pre-hanging component 5 and the time for the right heavy-duty hanging component 8 to move to the right pre-hanging component 7.

[0071] Further optimized, the left pre-mounted component 5, the right pre-mounted component 7, the left heavy-duty component 6, and the right heavy-duty component 8 are all cylindrical / disc-shaped structures.

[0072] Further optimized, both the first wire passage 61 and the second wire passage 81 are circular through holes; the diameter of the first wire passage 61 is smaller than the top surface diameter of the left weight-bearing bracket 6; the diameter of the second wire passage 81 is smaller than the top surface diameter of the right weight-bearing bracket 8; thus, the top surface of the right pre-mounted bracket 7 can become the support surface of the right weight-bearing bracket 8, and the top surface of the left pre-mounted bracket 5 can become the support surface of the left weight-bearing bracket 6.

[0073] Furthermore, the lifting arms are all designed as tray structures with cable holes / slots. The tray structure is used to receive the corresponding weighted loads during lifting. Each pre-loaded component can pass through the cable holes / slots of the corresponding lifting arm. Each lifting device includes a stepper motor and a vertically arranged screw drive platform. The tray structure is connected to the transmission slider of the screw drive platform, which ensures accuracy and further reduces vibration.

[0074] Further optimized, the left pre-mounted component 5 and the right pre-mounted component 7 have the same weight, the left weighted component 6 and the right weighted component 8 have the same weight, the left weighted component 6 is heavier than the left pre-mounted component 5, and the right weighted component 8 is heavier than the right pre-mounted component 7. This ensures that the tension on the first drying rod wire rope 200 is consistent with the tension on the second drying rod wire rope 300 during the test. Under the condition that the two have the same weight, the left pre-mounted component 5 and the right pre-mounted component 7 have the same volume, and the left weighted component 6 and the right pre-mounted component 7 have the same volume. This ensures that the environmental wind resistance received by the two is nearly consistent and facilitates uniform replacement of parts.

[0075] This embodiment further proposes a testing method using the ceiling-mounted clothes drying rack testing equipment described in any of the preceding embodiments, characterized by comprising the following steps performed in sequence:

[0076] Step 1: Connect the lead-out ends of the first drying pole wire rope 200 and the lead-out ends of the second drying pole wire rope 300 to the two ends of the crossbar 4 in a detachable manner.

[0077] Step 2: By controlling the unwinding mechanism of the clothes drying machine's wire rope, the crossbar 4 is reset to the starting position of the light-load crossbar rising during the lifting stroke of the crossbar 4;

[0078] Step 3: Conduct a test simulating the light-load descent of the clothes drying rack rod of the ceiling-mounted clothes drying machine: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar 4 is raised from the starting position of the light-load crossbar to the ending position of the light-load crossbar in the lifting stroke of the pre-loaded device.

[0079] Step 4: Control the unwinding mechanism of the clothes drying machine's wire rope to lower and reset the crossbar 4 to the starting position of the light-load crossbar's ascent;

[0080] Step 5: By controlling the lifting assembly 9, the weighted mounting device presses down on the pre-mounted device under the load, and then the weighted mounting device detaches from the lifting assembly 9.

[0081] Step 6: Conduct a test simulating the heavy load lifting of the clothes drying rack rod of the ceiling-mounted clothes drying machine: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar 4 overcomes the weight of the weight-bearing device and the pre-loaded device, and then descends from the starting position of the heavy load crossbar descent to the ending position of the heavy load crossbar descent in the lifting stroke of the crossbar 4.

[0082] Step 7: By controlling the lifting assembly 9, the weight-bearing device is lifted so that it is detached from the pre-attached device;

[0083] Step 8: When the crossbar 4 moves to a standard height position of the lifting stroke, measure whether the lengths of the first drying pole wire rope 200 and the second drying pole wire rope 300 are qualified.

[0084] The testing method proposed in this embodiment can accurately, efficiently, and labor-savingly perform standard stability tests on the steel wire ropes used to connect the drying rods of ceiling-mounted clothes drying racks under load, as well as accurately and efficiently detect the dimensional status of the steel wire ropes. This greatly improves the testing efficiency of ceiling-mounted clothes drying racks, and can accurately and quickly obtain test results, steel wire rope deformation and length results. It reduces the risk of manual input or operational errors in the clothes drying rack testing process, and can reduce detection errors caused by factors such as unbalanced force on the two steel wire ropes of the clothes drying rack, steel wire rope swaying or transmission interference, and vibration of the installed counterweight components. It more realistically simulates the actual working conditions when the clothes drying rack rods are raised and lowered, thus more accurately detecting faults in the steel wire ropes and their unwinding.

[0085] Example 2

[0086] like Figure 1 , Figure 2 , Figure 3 As shown:

[0087] This embodiment proposes a testing device for a ceiling-mounted clothes drying rack. The clothes drying rack includes a body 400, a wire rope unwinding mechanism disposed in the body 400, a first drying rod wire rope 200, and a second drying rod wire rope 300. Both the first and second drying rod wire ropes 200 and 300 are wound and connected to the wire rope unwinding mechanism. The lead ends of the first and second drying rod wire ropes 200 and 300 extend out from the left and right sides of the body 400, respectively. The testing device for the ceiling-mounted clothes drying rack includes a frame 1, a left test pull rope 2, a right test pull rope 3, a crossbar 4, a pre-loading device, a weight-bearing device, a lifting assembly 9, and a pull rope identification sensor assembly 10.

[0088] The frame 1 is provided with a test station, which is used to fix the horizontally arranged machine body 400 during testing;

[0089] The left test rope 2 is used as a test rope to provide vertical upward tension to the first drying pole wire rope 200. The left test rope 2 is bent vertically upward through a first pulley mechanism and then extends vertically downward.

[0090] The right test rope 3 is used as a test rope to provide vertical upward tension to the second drying pole wire rope 300. The right test rope 3 is bent vertically upward through a second pulley mechanism and then extends vertically downward.

[0091] During testing, the two ends of the crossbar 4 are detachably connected to the end of the first drying rod wire rope 200 and the end of the second drying rod wire rope 300, respectively; the two ends of the crossbar 4 are also fixedly connected to one end of the left test pull rope 2 and one end of the right test pull rope 3, respectively.

[0092] The left pre-mounted component 5 is fixedly connected to the other end of the left test pull rope 2, which extends vertically downward after being bent, so as to provide a vertical upward pull force to the crossbar 4 by its own weight in conjunction with the weight of the right pre-mounted component 7.

[0093] The left weight-bearing mount 6 is used to apply a load to the left pre-mounted mount 5 during testing;

[0094] The right pre-mounted component 7 is fixedly connected to the other end of the right test pull rope 3, which extends vertically downward after being bent, so as to provide a vertically upward pulling force to the crossbar 4 by its own weight in conjunction with the weight of the left pre-mounted component 5.

[0095] The right heavy-load mount 8 is used to apply a load to the right pre-mount 7 during testing;

[0096] The lifting assembly 9 is used to lift and support the left heavy-load mount 6 and the right heavy-load mount 8; when the lifting assembly 9 lowers the left heavy-load mount 6 and the right heavy-load mount 8 and the lifting assembly 9 does not apply force to the left heavy-load mount 6 and the right heavy-load mount 8, the left pre-mount mount 5, the right pre-mount mount 7, the left heavy-load mount 6 and the right heavy-load mount 8 together provide a vertical upward pulling force to both ends of the crossbar 4;

[0097] The rope identification sensor assembly 10 is mounted on the frame 1 and is used to identify the size and status of the first drying pole wire rope 200 and the second drying pole wire rope 300 during testing.

[0098] The ceiling-mounted clothes drying rack testing equipment of this embodiment allows a single operator to continuously perform stability tests on the wire rope structure and / or wire rope under light and heavy loads at the same testing station, as well as obtain test data on the dimensional status of the wire rope. This provides a testing equipment foundation for automated analysis and detection of faults in the wire rope unwinding mechanism, the wire rope structure, and / or the wire rope.

[0099] In a further optimized manner, the first drying rod wire rope 200 is led out from the left side of the machine body 400, and the second drying rod wire rope 300 is led out from the right side of the machine body 400.

[0100] In a further optimized manner, both the first pulley mechanism and the second pulley mechanism are located on the top of the frame 1, the test station is located on the longitudinal front side of the frame 1, and the lifting assembly 9 is located on the longitudinal rear side of the frame 1.

[0101] Further optimized, the first pulley mechanism is preferably a first pulley group, which includes a first front pulley 15 located at the left front part of the top of the frame 1 and a first rear pulley 16 located at the left rear part of the top of the frame 1; the second pulley mechanism is preferably a second pulley group, which includes a second front pulley 17 located at the right front part of the top of the frame 1 and a second rear pulley 18 located at the right rear part of the top of the frame 1; the left test rope 2 segment between the first front pulley 15 and the first rear pulley 16 is perpendicular to the lifting direction of the left pre-loaded component 5; the... The right test pull rope segment 3 between the second front pulley 17 and the second rear pulley 18 is perpendicular to the lifting direction of the right pre-loaded component 7; the left test pull rope segment 2 between the first front pulley 15 and the first rear pulley 16 is parallel to the right test pull rope segment 3 between the second front pulley 17 and the second rear pulley 18; this can more realistically simulate the heavy or light load hanging state of the clothes drying rack rod, reduce the relevant transmission friction, and make the test conditions closer to an actual working condition, thereby making the pull rope recognition sensor combination 10 more accurate.

[0102] Ideally, the left weight-bearing bracket 6 has a first cable passage 61 extending through its top and bottom surfaces, through which the left test pull rope 2 passes; the right weight-bearing bracket 8 has a second cable passage 81 extending through its top and bottom surfaces, through which the right test pull rope 3 passes. This facilitates a more realistic simulation of the working conditions of a clothes drying rack connected to a drying rod via a steel wire rope, avoiding related structural interference or unnecessary transmission friction interference. Thus, by analyzing the test data, the causes of failures due to the steel wire rope structure and / or the steel wire rope connecting the drying rod can be more accurately determined.

[0103] Ideally, the left pre-mounted component 5 and the right pre-mounted component 7 have the same weight; the left heavy-duty component 6 and the right heavy-duty component 8 have the same weight; the left heavy-duty component 6 is heavier than the left pre-mounted component 5; and the right heavy-duty component 8 is heavier than the right pre-mounted component 7.

[0104] Optimally, the lifting assembly 9 includes a left lifting device 91 with a left lifting arm 911 and a right lifting device 92 with a right lifting arm 921; the left lifting arm 911 is used to vertically lift the left heavy-duty mounting member 6; when the left lifting arm 911 leaves the left heavy-duty mounting member 6, the left lifting arm 911 does not contact the left pre-mounted member 5, and the weight of the left heavy-duty mounting member 6 is loaded onto the left pre-mounted member 5.

[0105] The right lifting arm 921 is used to vertically lift the right heavy-load component 8; when the right lifting arm 921 leaves the right heavy-load component 8, the right lifting arm 921 does not contact the right pre-load component 7, and the weight of the right heavy-load component 8 is loaded onto the right pre-load component 7; thus avoiding vibration generated when loading the heavy-load component.

[0106] Specifically, the left pre-loaded component 5 and the right pre-loaded component 7 are used to tighten the wire rope. During the light load test, the pre-loaded component can be detached from the corresponding weighted component.

[0107] Preferably, each lifting arm is designed as a tray structure with cable holes / slots. The tray structure is used to receive and lift the corresponding weighted load. Each pre-loaded component can pass through the cable holes / slots of the corresponding lifting arm. Each lifting device includes a stepper motor and a vertically arranged screw drive platform. The tray structure is connected to the transmission slider of the screw drive platform. This ensures accuracy and further reduces vibration.

[0108] Ideally, the left pre-mounted component 5, the right pre-mounted component 7, the left heavy-duty component 6, and the right heavy-duty component 8 are all cylindrical / disc-shaped structures.

[0109] Ideally, both the first wire passage 61 and the second wire passage 81 are circular through holes; the diameter of the first wire passage 61 is smaller than the top surface diameter of the left weight-bearing bracket 6; the diameter of the second wire passage 81 is smaller than the top surface diameter of the right weight-bearing bracket 8; thus, the top surface of the right pre-mounted bracket 7 can become the support surface of the right weight-bearing bracket 8, and the top surface of the left pre-mounted bracket 5 can become the support surface of the left weight-bearing bracket 6.

[0110] Further optimized, the two ends of the crossbar 4 are respectively provided with a first hook structure for hooking the end of the first drying pole wire rope 200 and a second hook structure for hooking the end of the second drying pole wire rope 300; this makes it convenient to install and remove the first drying pole wire rope 200 and the second drying pole wire rope 300 before and after testing.

[0111] Further optimized, the left pre-mounted component 5 and the right pre-mounted component 7 have the same volume; the left weighted component 6 and the right pre-mounted component 7 have the same volume; thus, the tension on the first drying pole wire rope 200 during the test is consistent with the tension on the second drying pole wire rope 300.

[0112] Furthermore, the frame 1 is also equipped with an obstacle detection and limiting mechanism 14; by blocking the descent of the ceiling clothes drying rack through the obstacle detection and limiting mechanism 14, an obstacle detection test is performed, saving manual labor to pull the steel wire rope to test the obstacle detection function; the obstacle detection and limiting mechanism 14 is located at the top of the frame 1, at or near the upper limit position of the upward stroke of the crossbar 4.

[0113] Specifically, the left heavy-load hanging component 6 and the right heavy-load hanging component 8 are preferably 17.5kg; the left pre-loading component 5 and the right pre-loading component 7 are preferably 0.3kg; the two clothes drying rack steel wire ropes pass through the middle round holes of the left heavy-load hanging component 6 and the right heavy-load hanging component 8 respectively, that is, the left and right light-load counterweights support the left and right heavy-load counterweights for the clothes drying rack heavy-load test. The left and right light-load counterweights can be freely tightened or detached from the left and right heavy-load counterweights. Tightening and detaching are quite flexible. This can save the physical exertion and time wasted by manually carrying 35kg counterweight sandbags when testing each machine. It also replaces the manual measurement of the difference in the reserved distance between the left and right steel wire ropes and avoids the risk of manual omission.

[0114] Specifically, the left test rope 2 and the right test rope 3 are of equal length.

[0115] Example 3

[0116] Example 3 is an optimized design of any one of the technical solutions in Example 2;

[0117] The ceiling-mounted clothes drying rack testing equipment also includes a controller 12; the pull rope identification sensor assembly 10 includes a first laser rangefinder 101 and a second laser rangefinder 102; the controller 12 is communicatively connected to the first laser rangefinder 101 and the second laser rangefinder 102 respectively; the first laser rangefinder 101 and the second laser rangefinder 102 are both mounted on the frame 1; the first laser detection point of the first laser rangefinder 101 is located at a first structural position at the same height as the end of the wire rope 200 of the first drying rod hanging on the crossbar 4, and is used to detect the distance between the first laser detection point and the fixed reference point of the first laser rangefinder 101; the second laser detection point of the second laser rangefinder 102 is located at a second structural position at the same height as the end of the wire rope 300 of the second drying rod hanging on the crossbar 4, and is used to detect the distance between the second laser detection point and the fixed reference point of the second laser rangefinder 102.

[0118] Further optimized, the first structure is located on the left end of the crossbar 4; the second structure is located on the right end of the crossbar 4; the first structure is located near the detachable connection point between the crossbar 4 and the first drying rod wire rope 200; the second structure is located near the detachable connection point between the crossbar 4 and the second drying rod wire rope 300.

[0119] Specifically, the length of the first drying rod wire rope 200 and the second drying rod wire rope 300 (i.e., the left and right wire ropes at both ends of the clothes drying rack) can be measured by laser distance sensors on both sides. When the deviation of the left and right wire ropes is ±1mm (the deviation value can be freely set), an alarm will be triggered to determine that it is unqualified. The testing equipment in this embodiment can avoid the occurrence of mismeasurement and omission due to manual measurement, and also saves manual testing time.

[0120] Optionally, the controller 12 is installed in a control box, and the controller 12 is also electrically connected to a foot switch and a touch screen.

[0121] Example 4

[0122] Example 4 is an optimized design of any one of the technical solutions in Example 2;

[0123] The ceiling-mounted clothes drying rack testing equipment also includes a limit detection sensor assembly 11; the controller 12 is electrically connected to the limit detection sensor assembly 11; the limit detection sensor assembly 11 is installed on the frame 1 and is used to detect the position of the crossbar 4.

[0124] Example 5

[0125] Example 5 is an optimized design of Example 4;

[0126] The limit detection sensor assembly 11 of the ceiling-mounted clothes drying rack testing equipment includes a first photoelectric detection switch 111, a second photoelectric detection switch 112, and a third photoelectric detection switch 113. All three switches are mounted on the frame 1. The first photoelectric detection switch 111 is vertically higher than the second photoelectric detection switch 112, and the second photoelectric detection switch 112 is vertically higher than the third photoelectric detection switch 113. The third photoelectric detection switch 113 is used to detect the horizontal bar. 4. The lowering limit position of the lifting stroke; the second photoelectric detection switch 112 is used to detect the horizontal bar 4 reaching a condition trigger position during the lifting process. When the horizontal bar 4 passes the condition trigger position and simulates the light-load descent of the ceiling clothes drying rack, the lifting assembly 9 that supports the left weight-bearing bracket 6 and the right weight-bearing bracket 8 begins to move closer to the left pre-mounted bracket 5 and the right pre-mounted bracket 7; the first photoelectric detection switch 111 is a detection switch that stops the lifting of the horizontal bar 4 when the first laser ranging sensor 101 and the second laser ranging sensor 102 detect the length of the wire rope.

[0127] Furthermore, the ceiling clothes drying rack testing equipment also includes a left pneumatic pressure plate mechanism 13 near the left side of the testing station and a right pneumatic pressure plate mechanism near the right side of the testing station (not shown in the attached diagram); specifically, both the left and right pneumatic pressure plate mechanisms 13 and 13 are mounted on the frame 1; the left and right pneumatic pressure plate mechanisms 13 and 13 press the bottom plate of the ceiling clothes drying rack with cylinders, thus eliminating the need for manual pressing with tools and external force, ensuring testing safety, accuracy, and efficiency.

[0128] Further optimized, the left pneumatic pressure plate mechanism 13 is equipped with a left moving screw platform to adjust the clamping position, and the right pneumatic pressure plate mechanism is equipped with a right moving screw platform to adjust the clamping position, thus enabling functional testing of clothes drying racks of different lengths.

[0129] In a further optimized manner, when the crossbar triggers the third photoelectric detection switch 113, it controls the power supply of the clothes drying machine to be disconnected, thus ensuring test safety.

[0130] Example 6

[0131] This embodiment proposes a testing method for a ceiling-mounted clothes drying rack testing device using any of the technical solutions in Embodiments 2, 3, 4, or 5, comprising the following steps performed in sequence:

[0132] Step S1: The lead-out ends of the first drying rod wire rope 200 and the lead-out ends of the second drying rod wire rope 300 are detachably connected to the two ends of the crossbar 4, respectively.

[0133] Step S2: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar 4 is reset to the starting position of the light load crossbar rising during the lifting stroke of the crossbar 4;

[0134] Step S3, conduct a test simulating the light-load descent of the clothes drying rack rod: by controlling the unwinding mechanism of the clothes drying rack wire rope, the crossbar 4 is raised from the starting position of the light-load crossbar to the ending position of the light-load crossbar rising stroke under the gravity pull of the left pre-loaded part 5 and the right pre-loaded part 7.

[0135] Step S4: Control the unwinding mechanism of the clothes drying machine's wire rope to lower and reset the crossbar 4 to the starting position of the light-load crossbar's ascent;

[0136] Step S5: By controlling the lifting assembly 9, the left heavy-load mounting piece 6 presses down on the left pre-mounted piece 5 under load, and then the left heavy-load mounting piece 6 disengages from the lifting assembly 9. The right heavy-load mounting piece 8 presses down on the right pre-mounted piece 7 under load, and then the right heavy-load mounting piece 8 disengages from the lifting assembly 9.

[0137] Step S6: Conduct a test simulating the heavy load rise of the clothes drying rack rod of the ceiling-mounted clothes drying machine: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar 4 overcomes the gravity of the left pre-loaded part 5, the right pre-loaded part 7, the left heavy loaded part 6 and the right heavy loaded part 8, and then descends from the starting position of the heavy load crossbar descent to the ending position of the heavy load crossbar descent in the lifting stroke of the crossbar 4.

[0138] Step S7: By controlling the lifting assembly 9 to lift the left heavy-load mount 6 so that the left heavy-load mount 6 is disengaged from the left pre-mount 5, and by controlling the lifting assembly 9 to lift the right heavy-load mount 8 so that the right heavy-load mount 8 is disengaged from the right pre-mount 7.

[0139] Step S8: When the crossbar 4 moves to a standard height position of the lifting stroke, check whether the lengths of the first drying pole wire rope 200 and the second drying pole wire rope 300 are qualified: compare and analyze the detection distance information obtained by the first laser rangefinder 101 and the second laser rangefinder 102 with several standard data to obtain the detection results of whether the lengths of the first drying pole wire rope 200 and the second drying pole wire rope 300 are qualified.

[0140] Further optimized, in step S1, the clothes drying machine can only be executed after the left pneumatic pressure plate mechanism 13 and the right pneumatic pressure plate mechanism clamp it; this can prevent the heavy-load counterweight loaded on the clothes drying machine's wire rope from suddenly pulling the clothes drying machine up.

[0141] In a further optimized manner, in step S2, when the crossbar 4 triggers the third photoelectric detection switch 113, the power supply to the clothes drying machine is disconnected; this ensures the integrity of the clothes drying machine during the testing process and prevents damage to the clothes drying machine under abnormal conditions.

[0142] In a further optimized manner, in step S3, when the crossbar 4 rises under the action of the left pre-loaded component 5 and the right pre-loaded component 7, it will stop after encountering the obstruction limiting mechanism 14 and then move in the opposite direction for 10 cm; the obstruction limiting mechanism 14 is set at or near the light load crossbar rising end position.

[0143] In a further optimized manner, S8 can be repeated three times in a test cycle to test the distance between the left and right wire ropes using the first laser ranging sensor 101 and the second laser ranging sensor 102. If the left / right distance deviation is less than or equal to the set value of the controller 12 system, the distance between the left and right wire ropes is deemed to be qualified; if the left / right distance deviation is greater than the set value of the controller 12 system, it is deemed to be unqualified.

[0144] Specifically, preparations before testing include: checking whether the power and air supply are turned on, and checking whether the pre-loaded components, the weighted components, the left and right steel wire ropes, and the steel wire rope hooks of the crossbar 4 are normal.

[0145] The specific operating instructions for the test equipment in this embodiment are as follows:

[0146] Test equipment power-on return to origin: 1.0. After power-on, the origin is reset: Place the clothes drying rack to be tested in the test station, step on the pressure plate foot pedal to press the bottom plate of the ceiling clothes drying rack tightly, then turn on the emergency stop button, and then reset the machine.

[0147] The specific testing process for steps S1 to S8 after powering on and returning to the origin is as follows:

[0148] Before step S1, clamp the power cord of the clothes dryer to the power socket and manually pair the clothes dryer remote control.

[0149] In step S2, if the clothes dryer does not stop automatically when the horizontal bar 4 descends to the starting position of the light load horizontal bar, the clothes dryer wire rope fixing rod will trigger the third photoelectric detection switch 113. Then the test equipment will forcibly disconnect the power supply of the clothes dryer to prevent the upper limit micro switch of the clothes dryer from malfunctioning and causing damage to the clothes dryer.

[0150] In step S3, the "lower" button on the clothes drying rack remote control is pressed manually, and the clothes drying rack enters the state of light-load lowering of the drying rod (i.e., the horizontal bar 4 rises). When the horizontal bar 4 rises and encounters the obstruction limit mechanism 14, the horizontal bar 4 will fall another 15-20 cm and then stop running (at this time, this height can be set as the rising end position of the light-load test process of the horizontal bar 4).

[0151] In step S4, when the crossbar 4 descends from the rising termination position of the light load test process to the detection position corresponding to the second photoelectric detection switch 112, step S5 is executed.

[0152] In step S5, the left lifting arm 911 and the right lifting arm 921 support the left heavy-load attachment 6 and the right heavy-load attachment 8 respectively, causing the left heavy-load attachment 6 and the right heavy-load attachment 8 to descend toward the left pre-attached attachment 5 and the right pre-attached attachment 7 respectively. When the left lifting arm 911 and the right lifting arm 921 descend more than five centimeters beyond the left pre-attached attachment 5 and the right pre-attached attachment 7, the left lifting device 91 and the right lifting device 92 stop operating. At this time, since the left heavy-load attachment 6 and the right heavy-load attachment 8 are detached from their respective lifting arms, the left heavy-load attachment 6 and the right heavy-load attachment 8 will press and hang on the left pre-attached attachment 5 and the right pre-attached attachment 7 respectively.

[0153] In step S6, after the left heavy-load hanging component 6 and the right heavy-load hanging component 8 are respectively hung on the left pre-hanging component 5 and the right pre-hanging component 7, the timer on the display screen of the test machine starts counting from 0 to 8 seconds (preparation time for heavy-load rise). After the system starts counting, the operator must press the "rise" button on the clothes drying rack remote control (the operation must be completed within the set 8 seconds). The clothes drying rack begins to simulate the heavy-load rise test of the ceiling clothes drying rack rod, that is, the heavy-load descent process of the crossbar 4.

[0154] In step S6, if a malfunction occurs in the micro switch of the clothes drying machine, that is, when the crossbar 4 descends to the position that triggers the third photoelectric detection switch 113, the controller 12 controls the disconnection of the power supply to the clothes drying machine.

[0155] In step S7, the user manually clicks the "Raise and lift counterweight" button on the display screen. The controller 12 controls the left lifting arm 911 and the right lifting arm 921 to rise, so that the weight of the left counterweight hanging part 6 and the right counterweight hanging part 8 is removed from the clothes drying machine wire rope.

[0156] In step S8, the first laser ranging sensor 101 and the second laser ranging sensor 102 respectively test the distance between the left and right steel wire ropes; if the length deviation of the left / right steel wire ropes is within the set limit of 1mm, the system determines that the length deviation of the left / right steel wire ropes is qualified; if it exceeds the limit, the length deviation of the left / right steel wire ropes is determined to be unqualified; then the controller 12 controls the left pneumatic pressure plate mechanism 13 and the right pneumatic pressure plate mechanism to release the pressure plates on the left and right sides of the clothes drying machine and execute the return to the origin process.

[0157] After step S8, remove the tested product: manually remove the left / right steel wire ropes of the clothes drying rack, and then disconnect the power supply of the clothes drying rack; manually place the tested product on the empty line fixture plate; the entire test is completed, and the process enters the waiting state for the next product to arrive for testing.

[0158] Example 7

[0159] Example 7 is an optimized design of any one of the technical solutions in Example 2;

[0160] The rope identification sensor assembly 10 is a visual recognition system used to identify the size and / or shape of the first and second drying pole wire ropes during testing.

[0161] Example 8

[0162] Example 8 is an optimized design of Example 5;

[0163] The first photoelectric detection switch 111, the second photoelectric detection switch 112, and the third photoelectric detection switch 113 are all through-beam photoelectric sensors, therefore, the first photoelectric detection switch 111, the second photoelectric detection switch 112, and the third photoelectric detection switch 113 are all set in pairs.

[0164] Example 9

[0165] This embodiment proposes a testing method for a ceiling-mounted clothes drying rack testing device as described in any of the technical solutions in Embodiment 5, including:

[0166] Step S1: Detachably connect the lead-out ends of the first drying pole wire rope 200 and the lead-out ends of the second drying pole wire rope 300 to the two ends of the crossbar 4; then proceed to step S2.

[0167] Step S2: Control the unwinding mechanism of the clothes drying machine wire rope to reset the crossbar 4 to the starting position of the light load crossbar rising during the lifting stroke of the crossbar 4; then execute step S3.

[0168] Step S3: Conduct a test simulating the light-load descent of the clothes drying rack rod of the ceiling-mounted clothes drying machine: By controlling the unwinding mechanism of the clothes drying machine wire rope, the crossbar 4 is raised from the starting position of the light-load crossbar rise to the ending position of the light-load crossbar rise in the lifting stroke of the crossbar 4 under the gravity pull of the left pre-loaded part 5 and the right pre-loaded part 7; then execute step S4.

[0169] Step S4: Control the unwinding mechanism of the clothes drying machine's wire rope to lower and reset the crossbar 4 to the starting position of the light-load crossbar; then execute step S45.

[0170] Step S45: When the second photoelectric detection switch 112 is triggered by the crossbar 4, the lifting assembly 9 that supports the left heavy-duty mounting piece 6 and the right heavy-duty mounting piece 8 begins to move closer to the left pre-mounted piece 5 and the right pre-mounted piece 7; then step S5 is executed.

[0171] Step S5: By controlling the lifting assembly 9, the left heavy-load mounting piece 6 presses down on the left pre-mounted piece 5 under load, and then the left heavy-load mounting piece 6 disengages from the lifting assembly 9; and the right heavy-load mounting piece 8 presses down on the right pre-mounted piece 7 under load, and then the right heavy-load mounting piece 8 disengages from the lifting assembly 9; then proceed to step S6.

[0172] Step S6: Conduct a test simulating the heavy-load rise of the clothes drying rack's rod: By controlling the clothes drying rack's wire rope unwinding mechanism, the crossbar 4 overcomes the gravity of the left pre-loaded component 5, the right pre-loaded component 7, the left heavy-loaded component 6, and the right heavy-loaded component 8, and then descends from the starting position of the heavy-load crossbar descent to the ending position of the heavy-load crossbar descent during the lifting stroke of the crossbar 4; then execute step S7;

[0173] Step S7: By controlling the lifting assembly 9 to lift the left heavy-duty mount 6 so that the left heavy-duty mount 6 is disengaged from the left pre-mount 5, and by controlling the lifting assembly 9 to lift the right heavy-duty mount 8 so that the right heavy-duty mount 8 is disengaged from the right pre-mount 7; then proceed to step S8.

[0174] Step S8: When the crossbar 4 moves to a standard height position of the lifting stroke, check whether the lengths of the first drying pole wire rope 200 and the second drying pole wire rope 300 are qualified: compare and analyze the detection distance information obtained by the first laser rangefinder 101 and the second laser rangefinder 102 with several standard data to obtain the detection results of whether the lengths of the first drying pole wire rope 200 and the second drying pole wire rope 300 are qualified.
