[0002] Before leaving the factory, the ceiling clothes drying machine needs to be tested for performance items including electrical, mechanical transmission and safety. When testing with the existing performance test rack equipment used for ceiling clothes drying machines, at least two operators are required to move the ceiling clothes drying machine to the equipment, and then during the test process, they need to manually carry and hang dozens of kilograms of mounting parts (such as sandbags) for counterweight testing, which not only increases the labor intensity, but also prolongs the test time.

[0078] Step 3, a test is performed to simulate the light-load descent of the ceiling clothes drying rod: the wire rope unwinding mechanism of the clothes drying rod is controlled to make the cross bar 4 rise from the light-load cross bar rise starting position to a light-load cross bar rise ending position of the cross bar 4 lifting stroke under the gravity pull of the pre-mounted device;

[0079] Step 4, controlling the unwinding mechanism of the wire rope of the clothes drying machine to lower the cross bar 4 and reset it to the rising starting position of the light-load cross bar;

[0080] Step 5, by controlling the lifting assembly 9, the weighted mounting device is pressed down on the pre-mounting device with a load, and then the weighted mounting device is separated from the lifting assembly 9;

[0081] Step 6, a test is performed to simulate the heavy-loaded rise of the clothes drying rod of the ceiling clothes drying machine: the wire rope unwinding mechanism of the clothes drying machine is controlled to make the cross bar 4 overcome the gravity of the weighted mounting device and the pre-mounting device, and then the cross bar 4 is lowered from a heavy-loaded cross bar lowering starting position of the lifting stroke of the cross bar 4 to a heavy-loaded cross bar lowering ending position;

[0082] Step 7, lifting the weighted mounting device by controlling the lifting assembly 9 so that the weighted mounting device is separated from the pre-mounting device;

[0083] Step eight, when the cross bar 4 moves to a standard height position of the lifting stroke, measure whether the lengths of the first drying rod steel wire rope 200 and the second drying rod steel wire rope 300 are qualified.

[0084] The testing method proposed in the present embodiment can accurately, efficiently and labor-savingly perform stability standard testing on the steel wire rope used to connect the clothes drying rod of the ceiling clothes drying machine under a loaded state, and accurately and efficiently detect the size status of the steel wire rope, thereby greatly improving the testing efficiency of the ceiling clothes drying machine, and can accurately and quickly obtain the test results, steel wire rope deformation and length results, reducing the risk of manual input or operational errors in the clothes drying machine testing process, and can reduce the detection errors caused by factors such as unbalanced force on the two steel wire ropes of the clothes drying machine, shaking or transmission interference of the steel wire rope, and vibration of the installed counterweight components, and more realistically simulate the actual working conditions of the lifting and hanging of the clothes drying rod, thereby more accurately detecting faults of the clothes drying machine steel wire rope and its unwinding.

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

[0087] The present embodiment provides a ceiling clothes drying machine test device, the clothes drying machine includes a machine body 400, a wire rope unwinding mechanism provided in the machine body 400, a first drying rod wire rope 200 and a second drying rod wire rope 300, the first drying rod wire rope 200 and the second drying rod wire rope 300 are both wound and connected with the wire rope unwinding mechanism, the first wire end of the first drying rod wire rope 200 and the second wire end of the second drying rod wire rope 300 extend out of the left and right sides of the machine body 400 respectively, the ceiling clothes drying machine test device includes a frame 1, a left test pull rope 2, a right test pull rope 3, a cross bar 4, a pre-mounting device, a weighted mounting device, a lifting component 9 and a pull rope identification sensor assembly 10:

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

[0089] The left test pull rope 2 is used as a test pull rope to provide vertical upward pulling force for the first drying rod steel wire rope 200. The left test pull rope 2 extends vertically upward, is bent through a first pulley mechanism, and then extends vertically downward.

[0090] The right test pull rope 3 is used as a test pull rope to provide vertical upward pulling force for the second drying rod wire rope 300. The right test pull rope 3 extends vertically upward, is bent by a second pulley mechanism, and then extends vertically downward.

[0091] During the test, the two ends of the crossbar 4 are detachably connected to the outgoing end of the first drying rod steel wire rope 200 and the outgoing end of the second drying rod steel wire rope 300; the two ends of the crossbar 4 are 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-mounting member 5 is fixedly connected to the other end of the left test rope 2 that extends vertically downward after being bent, and is used to provide a vertical upward pulling force for the crossbar 4 by cooperating with the gravity of the right pre-mounting member 7 through its own gravity;

[0093] The left weighted mounting part 6 is used to load and press down the left pre-mounting part 5 during testing;

[0094] The right pre-mounting member 7 is fixedly connected to the other end of the right test rope 3 extending vertically downward after being bent, and is used to provide a vertical upward pulling force for the crossbar 4 by cooperating with the gravity of the left pre-mounting member 5 through its own gravity;

[0095] The right weighted mounting part 8 is used to load and press down the right pre-mounting part 7 during testing;

[0096] The lifting assembly 9 is used to lift and support the left weighted mounting member 6 and the right weighted mounting member 8; when the lifting assembly 9 puts down the left weighted mounting member 6 and the right weighted mounting member 8 and the lifting assembly 9 does not apply force to the left weighted mounting member 6 and the right weighted mounting member 8, the left pre-mounting member 5, the right pre-mounting member 7, the left weighted mounting member 6 and the right weighted mounting member 8 jointly provide vertical upward pulling force for the two ends of the crossbar 4;

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

[0098] The ceiling clothes drying machine testing equipment of the present embodiment can continuously complete the stability test of the retractable wire rope structure and / or the wire rope under light and heavy load conditions and obtain the test data of the wire rope size status by one operator at the same test station, thereby providing a testing equipment basis for the automated analysis and detection of faults of the wire rope unwinding mechanism, the retractable wire rope structure and / or the wire rope.

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

[0100] Further optimized, the first pulley mechanism and the second pulley mechanism are both arranged on the top of the frame 1 , the testing 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 block, the first pulley block 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 block, the second pulley block 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 section of the left test rope 2 between the first front pulley 15 and the first rear pulley 16 is perpendicular to the lifting direction of the left pre-mounting member 5; The right test rope 3 section between the second front pulley 17 and the second rear pulley 18 is perpendicular to the lifting direction of the right pre-mounted component 7; the left test rope 2 section between the first front pulley 15 and the first rear pulley 16 is spaced parallel to the right test rope 3 section between the second front pulley 17 and the second rear pulley 18; in this way, the heavy load or light load hanging state of the clothes drying rack can be more realistically simulated, the relevant transmission friction can be reduced, and the test conditions can be closer to an actual working state, thereby making the rope identification sensor combination 10 detect more accurately.

[0102] Optimally, a first wire opening 61 is provided through the top and bottom surfaces of the left weighted mounting member 6, and the left test rope 2 passes through the first wire opening 61; a second wire opening 81 is provided through the top and bottom surfaces of the right weighted mounting member 8, and the right test rope 3 passes through the second wire opening 81; this is conducive to simulating a more realistic working condition of a clothes drying machine connected to a clothes drying rod through a steel wire rope, avoiding related structural interference or increasing unnecessary transmission friction interference, so that through analysis of the detection data, the cause of failure caused by the steel wire rope retracting and releasing structure and / or the steel wire rope connecting the clothes drying rod can be obtained more accurately.

[0103] Optimally, the left pre-mounting component 5 and the right pre-mounting component 7 are of equal weight; the left weighted mounting component 6 and the right weighted mounting component 8 are of equal weight; the left weighted mounting component 6 is heavier than the left pre-mounting component 5; and the right weighted mounting component 8 is heavier than the right pre-mounting component 7.

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

[0105] 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-mounting component 7, and the right weighted mounting component 8's own weight is loaded on the right pre-mounting component 7; this avoids the vibration generated when loading the weighted mounting component.

[0106] Specifically, the left pre-mounting member 5 and the right pre-mounting member 7 are used to tighten the steel wire rope, and the pre-mounting members can be separated from the corresponding weighted mounting members during the light load test.

[0107] Preferably, the lifting arms are designed as tray structures with wire holes / grooves, and the corresponding weighted mounting parts are received and lifted through the tray structure. Each pre-mounted part can pass through the wire holes / grooves of the corresponding lifting arms; each lifting device includes a stepper motor and a vertically arranged screw transmission platform, and the tray structure is connected to the transmission slider of the screw transmission platform, which can ensure accuracy and further reduce vibration.

[0108] Optimally, the left pre-mounting component 5, the right pre-mounting component 7, the left weighted mounting component 6 and the right weighted mounting component 8 are all cylindrical / pancake-shaped structures.

[0109] Optimally, the first wire passing opening 61 and the second wire passing opening 81 are both circular through holes; the diameter of the first wire passing opening 61 is smaller than the top surface diameter of the left weighted mounting component 6; the diameter of the second wire passing opening 81 is smaller than the top surface diameter of the right weighted mounting component 8; in this way, the top surface of the right pre-mounting component 7 can become the supporting surface of the right weighted mounting component 8, and the top surface of the left pre-mounting component 5 can become the supporting surface of the left weighted mounting component 6.

[0110] For further optimization, the two ends of the cross bar 4 are respectively provided with a first hook structure for hooking the tail end of the first drying rod steel wire rope 200 and a second hook structure for hooking the tail end of the second drying rod steel wire rope 300; this makes it convenient to install and remove the first drying rod steel wire rope 200 and the second drying rod steel wire rope 300 before and after testing.

[0111] Further optimized, the left pre-mounting part 5 and the right pre-mounting part 7 are equal in volume; the left weighted mounting part 6 and the right pre-mounting part 7 are equal in volume; in this way, the tension exerted on the first drying rod steel wire rope 200 during the test can be consistent with the tension exerted on the second drying rod steel wire rope 300.

[0112] For further optimization, the frame 1 is also provided with an obstruction limiting mechanism 14; the obstruction limiting mechanism 14 is used to block the ceiling clothes drying machine from descending, that is, an obstruction test is performed, saving manpower to pull the wire rope by hand to test the obstruction function; the obstruction limiting mechanism 14 is arranged at the top of the frame 1, at or near the upper limit position of the rising stroke of the cross bar 4.

[0113] Specifically, the left weighted mounting part 6 and the right weighted mounting part 8 are preferably 17.5kg; the left pre-mounting part 5 and the right pre-mounting part 7 are preferably 0.3kg; the two clothes drying machine steel ropes pass through the middle circular holes of the left weighted mounting part 6 and the right weighted mounting part 8 respectively, that is, the left and right light-loaded counterweights are used to support the left and right heavy-loaded counterweights to carry out the heavy-load test of the clothes drying machine. The left and right light-loaded counterweights can be freely tightened or detached from the left and right heavy-loaded counterweights, and the tightening and detaching are quite flexible. In this way, the physical exertion and waste of time required to manually carry 35kg of counterweight sandbags when testing each machine can be saved, and the manual measurement of the difference in the reserved distances of the left and right steel ropes is replaced, while also avoiding the risk of manual omission.

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

[0115] Example 3

[0116] Embodiment 3 is an optimized design of any technical solution in Embodiment 2;

[0117] The ceiling clothes drying machine testing equipment also includes a controller 12; the rope identification sensor combination 10 includes a first laser ranging sensor 101 and a second laser ranging sensor 102; the controller 12 is respectively connected to the first laser ranging sensor 101 and the second laser ranging sensor 102 for communication; the first laser ranging sensor 101 and the second laser ranging sensor 102 are both installed on the frame 1; the first laser ranging sensor 101 The first laser detection point of the first laser ranging sensor 101 is located at a first structural position that maintains the same height as the outlet end of the first drying rod steel wire rope 200 hung on the cross bar 4, and is used to detect the distance between the first laser detection point and the fixed reference point of the first laser ranging sensor 101; the second laser detection point of the second laser ranging sensor 102 is located at a second structural position that maintains the same height as the outlet end of the second drying rod steel wire rope 300 hung on the cross bar 4, and is used to detect the distance between the second laser detection point and the fixed reference point of the second laser ranging sensor 102.

[0118] Further optimized, the first structural position is located on the left end of the cross bar 4; the second structural position is located on the right end of the cross bar 4; the first structural position is close to the detachable connection point between the cross bar 4 and the first drying rod steel wire rope 200; the second structural position is close to the detachable connection point between the cross bar 4 and the second drying rod steel wire rope 300.

[0119] Specifically, the pay-out length test of the first drying rod steel wire rope 200 and the second drying rod steel wire rope 300 (i.e., the left and right steel wire ropes connecting the two ends of the drying rod of the clothes drying machine) can be measured by the laser ranging sensors on the left and right sides. When the deviation of the left and right steel wire ropes is plus or minus 1mm (the deviation value can be set freely), an alarm will be issued to determine that it is unqualified. Testing the steel wire rope distance through the testing equipment of this embodiment can avoid the occurrence of manual measurement errors and missed measurements, and relatively save manual testing time.

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

[0121] Example 4

[0122] Embodiment 4 is an optimized design of any technical solution in Embodiment 2;

[0123] The ceiling clothes drying machine 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 cross bar 4.

[0124] Example 5

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

[0126] The limit detection sensor combination 11 of the ceiling clothes drying machine test equipment includes a first photoelectric detection switch 111, a second photoelectric detection switch 112 and a third photoelectric detection switch 113; the first photoelectric detection switch 111, the second photoelectric detection switch 112 and the third photoelectric detection switch 113 are all installed on the frame 1, the first photoelectric detection switch 111 is vertically higher than the second photoelectric detection switch 112 in terms of installation height, and the second photoelectric detection switch 112 is vertically higher than the third photoelectric detection switch 113 in terms of installation height; the third photoelectric detection switch 113 is used to detect the cross bar 4 is the descending limit position of the lifting stroke; the second photoelectric detection switch 112 is used to detect that the cross bar 4 reaches a conditional trigger position during the lifting process. When the cross bar 4 passes the conditional trigger position and simulates the light-load descent of the ceiling clothes drying machine, the lifting assembly 9 that supports the left weighted mounting part 6 and the right weighted mounting part 8 begins to move closer to the left pre-mounting part 5 and the right pre-mounting part 7; the first photoelectric detection switch 111 is used as a detection switch that stops the lifting of the cross bar 4 when the first laser ranging sensor 101 and the second laser ranging sensor 102 detect the length of the wire rope.

[0127] For further optimization, the ceiling clothes drying machine 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 drawings); specifically, the left pneumatic pressure plate mechanism 13 and the right pneumatic pressure plate mechanism are both installed on the frame 1; the left pneumatic pressure plate mechanism 13 and the right pneumatic pressure plate mechanism press the bottom plate of the ceiling clothes drying machine through cylinders, so there is no need for manual tools and external force to press the plate, which can ensure test safety, accuracy and efficiency.

[0128] For further optimization, the left pneumatic pressure plate mechanism 13 is equipped with a left movable screw platform to adjust the clamping position, and the right pneumatic pressure plate mechanism is equipped with a right movable screw platform to adjust the clamping position, so that it can be compatible with functional tests of clothes drying machines of different lengths.

[0129] Further optimized, when the cross bar triggers the third photoelectric detection switch 113, the power supply of the clothes drying machine is disconnected, thus ensuring the safety of the test.

[0130] Example 6

[0131] This embodiment proposes a test method using the ceiling clothes drying machine test device as described in any one of the technical solutions in Embodiment 2, Embodiment 3, Embodiment 4 or Embodiment 5, including the following steps performed in sequence:

[0132] Step S1, the outgoing wire end of the first drying rod steel wire rope 200 and the outgoing wire end of the second drying rod steel wire rope 300 are detachably connected to the two ends of the cross bar 4 respectively;

[0133] Step S2, controlling the wire rope unwinding mechanism of the clothes drying machine to reset the cross bar 4 to a light-load cross bar rising starting position in the cross bar 4 lifting stroke;

[0134] Step S3, a test is performed to simulate the light-load descent of the ceiling clothes drying rod: the wire rope unwinding mechanism of the clothes drying rod is controlled to make the cross bar 4 rise from the light-load cross bar rise starting position to a light-load cross bar rise ending position of the cross bar 4 lifting stroke under the gravity pull of the left pre-mounting part 5 and the right pre-mounting part 7;

[0135] Step S4, controlling the wire rope unwinding mechanism of the clothes drying machine to lower the cross bar 4 and reset it to the rising starting position of the light-load cross bar;

[0136] Step S5, by controlling the lifting assembly 9, the left weighted mounting part 6 is pressed down on the left pre-mounting part 5 with the load, and then the left weighted mounting part 6 is separated from the lifting assembly 9, and the right weighted mounting part 8 is pressed down on the right pre-mounting part 7 with the load, and then the right weighted mounting part 8 is separated from the lifting assembly 9;

[0137] Step S6, performing a test simulating the heavy-loaded rising of the clothes drying rod of the ceiling clothes drying machine: controlling the unwinding mechanism of the wire rope of the clothes drying machine to make the cross bar 4 overcome the gravity of the left pre-mounting part 5, the right pre-mounting part 7, the left weighted mounting part 6 and the right weighted mounting part 8, and then descending from a heavy-loaded cross bar descending starting position of the lifting stroke of the cross bar 4 to a heavy-loaded cross bar descending ending position;

[0138] Step S7, lifting the left weighted mounting member 6 by controlling the lifting assembly 9 to separate the left weighted mounting member 6 from the left pre-mounting member 5, and lifting the right weighted mounting member 8 by controlling the lifting assembly 9 to separate the right weighted mounting member 8 from the right pre-mounting member 7;

[0139] Step S8, when the cross bar 4 moves to a standard height position in the lifting stroke, detect whether the lengths of the first drying rod steel wire rope 200 and the second drying rod steel wire rope 300 are qualified: compare and analyze the detection distance information obtained by the first laser ranging sensor 101 and the second laser ranging sensor 102 with a number of standard data to obtain the detection result of whether the lengths of the first drying rod steel wire rope 200 and the second drying rod steel wire rope 300 are qualified.

[0140] Further optimized, in step S1, step S2 can be executed only after the clothes drying machine is clamped by the left pneumatic pressure plate mechanism 13 and the right pneumatic pressure plate mechanism; this can prevent the heavy load counterweight external force loaded on the steel wire rope of the clothes drying machine from suddenly pulling up the clothes drying machine.

[0141] Further optimized, as in step S2, when the cross bar 4 triggers the third photoelectric detection switch 113, the power supply of the clothes drying machine is disconnected; this can ensure the integrity of the clothes drying machine during the test to avoid damage to the clothes drying machine under abnormal circumstances.

[0142] Further optimized, in step S3, when the cross bar 4 rises under the action of the left pre-mounting part 5 and the right pre-mounting part 7, it encounters the resistance limiting mechanism 14 and then runs in the opposite direction for 10CM before stopping; the resistance limiting mechanism 14 is set at or near the rising end position of the light-load cross bar.

[0143] For further optimization, S8 can be repeatedly executed three times in one test cycle, and the distance test of the left and right wire ropes is performed by the first laser ranging sensor 101 and the second laser ranging sensor 102. When the left / right distance deviation is less than or equal to the setting value of the controller 12 system, the distance of the left and right wire ropes is judged to be qualified, and when the left / right distance deviation is greater than the setting value of the controller 12 system, it is judged to be unqualified.

[0144] Specifically, preparations are made before the test: check whether the power supply and gas source are turned on, and check whether the pre-mounted parts, the weighted mounting parts, the left and right wire ropes, and the wire rope hooks of the crossbar 4 are normal.

[0145] The specific operation instructions of the test equipment of this embodiment are as follows:

[0146] The test equipment returns to the origin when it is turned on: 1.0. After turning on, the origin is reset: put the clothes drying machine to be tested on the test station, step on the pressure plate and the equipment will press the bottom plate of the ceiling clothes drying machine, then turn on the emergency stop button and reset the machine.

[0147] The specific test process of step S1 to step S8 after the machine is turned on and returns to the origin is as follows:

[0148] Before step S1, the power cord of the clothes drying machine is clamped to the power socket, and the clothes drying machine remote control is manually paired.

[0149] In step S2, the "up" button of the remote control is manually pressed. If the clothes dryer does not stop automatically when the cross bar 4 descends to the light-load cross bar rising starting position, the clothes dryer wire rope fixing rod will trigger the third photoelectric detection switch 113, and then the test equipment will forcibly disconnect the power supply of the clothes dryer to prevent the upper limit microswitch of the clothes dryer from malfunctioning and causing damage to the clothes dryer.

[0150] In step S3, the "down" button of the clothes drying machine remote control is manually pressed, and the clothes drying machine is in a state of entering a light-load descending state of the clothes drying rod (i.e., the cross bar 4 rises). When the cross bar 4 rises and hits the resistance limit mechanism 14, the cross bar 4 drops another 15-20 cm and then stops running (at this time, this height can be set as the rising end position of the light-load test process of the cross bar 4).

[0151] In step S4 , when the crossbar 4 is lowered from the rising end 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 weighted mounting component 6 and the right weighted mounting component 8 respectively, so that the left weighted mounting component 6 and the right weighted mounting component 8 respectively descend toward the left pre-mounting component 5 and the right pre-mounting component 7, until the left lifting arm 911 and the right lifting arm 921 descend beyond the left pre-mounting component 5 and the right pre-mounting component 7 by five centimeters, then the left lifting device 91 and the right lifting device 92 stop running. At this time, the left weighted mounting component 6 and the right weighted mounting component 8 are separated from their corresponding lifting arms, so the left weighted mounting component 6 and the right weighted mounting component 8 will be pressed and hung on the left pre-mounting component 5 and the right pre-mounting component 7 respectively.

[0153] In step S6, after the left weighted mounting member 6 and the right weighted mounting member 8 are respectively pressed and hung on the left pre-mounting member 5 and the right pre-mounting member 7, the timer on the display screen of the test machine starts timing from 0 to 8S (heavy-load rising preparation time). After the system starts timing, you need to manually press the "up" button on the clothes drying machine remote control (pressing the up button on the remote control must be completed within the set 8S), and the clothes drying machine starts to simulate the test of the heavy-load rising of the ceiling clothes drying machine rod, that is, the heavy-load descending process of the cross bar 4.

[0154] In step S6 , if the micro switch of the clothes drying machine is abnormal, that is, when the cross bar 4 drops to the position of triggering the third photoelectric detection switch 113 , the controller 12 controls to disconnect the power supply of the clothes drying machine.

[0155] In step S7, the "raise and take counterweight" button on the display screen is manually clicked, and 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 mounting part 6 and the right counterweight mounting part 8 are separated from the clothes drying machine wire rope.

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

[0157] After step S8, take out the tested product: manually remove the left / right wire rope of the clothes drying machine, and then remove the power supply of the clothes drying machine; manually put the tested product on the line body tooling board with empty space; the whole test is completed, and enter the waiting state for the next product to arrive for testing.

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

[0164] Example 9

[0165] This embodiment proposes a testing method using the ceiling clothes drying machine testing device as described in any technical solution in Embodiment 5, including:

[0166] Step S1, the outgoing wire end of the first drying rod steel wire rope 200 and the outgoing wire end of the second drying rod steel wire rope 300 are detachably connected to the two ends of the cross bar 4 respectively; then step S2 is executed;

[0167] Step S2, by controlling the unwinding mechanism of the wire rope of the clothes drying machine, the cross bar 4 is reset to a light-load cross bar rising starting position of the cross bar 4 lifting stroke; then executing step S3;

[0168] Step S3, a test is performed to simulate the light-load descent of the ceiling clothes drying rod: the wire rope unwinding mechanism of the clothes drying rod is controlled to make the cross bar 4 rise from the light-load cross bar rise starting position to a light-load cross bar rise ending position of the cross bar 4 lifting stroke under the gravity pull of the left pre-mounting part 5 and the right pre-mounting part 7; then step S4 is executed;

[0169] Step S4, controlling the wire rope unwinding mechanism of the clothes drying machine to lower the cross bar 4 and reset it to the rising starting position of the light-load cross bar; then executing step S45;
