Description

Technical Field

[0001] This utility model relates to the field of clothes drying rack testing technology, specifically to a ceiling-mounted clothes drying rack testing device. 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. Utility Model Content

[0003] In view of this, it is necessary to propose a testing device for ceiling-mounted clothes drying racks to overcome some of the shortcomings of the aforementioned 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 utility model proposes a testing device for a ceiling-mounted clothes drying rack. The clothes drying rack includes a body, a wire rope unwinding mechanism disposed in 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.

[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] The beneficial effects of this utility model are as follows:

[0024] 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, reduces the risk of manual input or operational errors during the testing process, and 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.

[0033] Example 1

[0034] like Figure 1 As shown:

[0035] 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:

[0036] The frame 1 is provided with a test station, which is used to fix the machine body 400 during testing;

[0037] 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;

[0038] 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.

[0039] 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.

[0040] 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;

[0041] Weighted mounting device ( Figure 1 (Not shown), used to apply a load to the pre-mounted device during testing;

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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;

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Example 2

[0058] like Figure 1 , Figure 2 , Figure 3 As shown:

[0059] 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.

[0060] The frame 1 is provided with a test station, which is used to fix the horizontally arranged machine body 400 during testing;

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] The left weight-bearing mount 6 is used to apply a load to the left pre-mounted mount 5 during testing;

[0066] 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.

[0067] The right heavy-load mount 8 is used to apply a load to the right pre-mount 7 during testing;

[0068] 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;

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Specifically, the left test rope 2 and the right test rope 3 are of equal length.

[0091] 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.

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.

[0099] 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.
