Description

Technical Field

[0001] This utility model relates to the field of electric clothes drying rack technology, specifically an electric clothes drying rack detection device. Background Technology

[0002] Electric clothes drying racks are common appliances in modern homes. Their core function is to raise and lower the drying rod by extending and retracting the traction rope through a drive mechanism inside the main unit. As a key load-bearing and transmission component, the durability, fatigue resistance, and wear resistance of the traction rope and other guiding components directly affect the overall lifespan and operational safety of the product.

[0003] In existing technologies, the testing of traction ropes mainly focuses on static performance or single destructive tests, such as focusing on its single tensile strength or preliminary wear observation. This one-time testing method cannot simulate the long-term, continuous reciprocating motion process that the traction rope undergoes in actual use. Therefore, it is difficult to effectively expose and evaluate its dynamic durability indicators such as fatigue damage, structural deterioration and wear resistance under cyclic stress, resulting in a weak correlation between the test results and the actual service life.

The reciprocating movement mechanism also includes a dovetail guide rail 7 fixedly connected between the bottom ends of the two bearing seats 4, and a dovetail guide block 8 fixedly connected to the middle of the bottom end of the reciprocating nut 6. The dovetail guide block 8 slides with the dovetail groove of the dovetail guide rail 7. The frame 2 is fixedly connected to the bottom end of the testing table 1. A counterweight mechanism is provided on the frame 2. The counterweight mechanism includes an inclined platform 18 fixedly connected to the upper bottom end of the frame 2. A counterweight block 19 is provided at the top of the inclined platform 18. Rollers 20 are rotatably connected to the four corners of the bottom end of the counterweight block 19 through bearings. Openings are provided on both sides of the top end of the inclined platform 18. There is a rolling groove 21 adapted to the roller 20. The roller 20 is housed in the rolling groove 21 and rolls in contact with it. A fixed head 22 is fixedly connected to the front of the counterweight 19. A rope hole is opened through the middle of the fixed head 22. A limit baffle 23 is fixedly connected to the outer side of the bottom left side of the frame 2. A guide mechanism is set between the reciprocating moving mechanism and the right side of the frame 2. The guide mechanism includes a horizontal bar 24 fixedly connected to the middle of the right side of the frame 2, and a wheel frame 25 fixedly connected to the horizontal bar 24 and the top of the right side bearing 4. The upper and lower ends of the wheel frame 25 are rotatably connected to pulleys 26 through bearings. An avoidance groove 27 is opened in the middle of the top right side of the inclined platform 18.

[0026] In this embodiment, the coordinated use of motor 3, reciprocating screw 5 and clamping mechanism realizes stable and continuous automatic reciprocating winding and unwinding motion of the traction rope, simulating its long-term real-world use conditions, and solving the problem that existing one-time testing methods cannot assess the fatigue resistance and dynamic durability of the traction rope.

[0027] Furthermore, the combined use of pulley 26, counterweight 19 and inclined platform 18 provides a constant and automatically resettable simulated load for the traction rope, ensuring the stability and consistency of the load throughout the entire cyclic test.

[0028] Working principle: During testing, firstly, the free end of the traction rope to be tested for the electric clothes drying rack is passed sequentially through the tension sleeve 10 and the fixing sleeve 9. Then, the locking screw 12 is tightened, and its lower end presses the arc-shaped clamp 11 downward, pressing the end of the traction rope against the inner wall of the fixing sleeve 9 to complete the initial fixation. Subsequently, the nut sleeve 16 is tightened. The nut sleeve 16 is screwed into the threaded groove 17 on the outer wall of the tension sleeve 10, pressing the tension groove 15 opened on the tension sleeve 10 to narrow, reducing its inner diameter, thereby uniformly gripping the traction rope from the circumference, forming a second layer to prevent it from slipping off under tension. After securing one end of the traction rope, pass the other end downwards over the pulley 26 above the right-side bearing 4, turning it downwards. Then, guide the rope towards the frame 2 and upwards over the pulley 26 above the crossbar 24, extending it diagonally again. Pass it through the rope hole on the fixing head 22, and finally securely connect the end of the rope segment to the fixing head 22 of the counterweight 19 using a rope clamp or knot. After installation, set the required test time and number of cycles using the controller 28, and then start the motor 3. The motor 3 drives the reciprocating screw 5 to rotate forward and backward. This causes the reciprocating nut 6, which is threaded to it, and the entire clamping mechanism fixed thereto to perform stable reciprocating linear motion along the path constrained by the dovetail guide block 8 and the dovetail guide rail 7. This motion forces the clamped traction rope to be continuously pulled out and retracted, simulating its cyclic release and retraction process in actual use. During this process, the counterweight block 19, which is always pulled by the rope, provides a constant tensile load to the traction rope. The roller 20 of the counterweight block 19 is embedded in the rolling groove 21 of the inclined platform 18, converting sliding friction into rolling friction, so that the counterweight block 19 can move with the traction rope. The device rolls back and forth on the inclined platform 18. Due to the inclined design of the platform 18, when the traction rope is relaxed, the counterweight 19 can automatically roll back to the initial position under its own weight, providing pretension for the next rope pull. The controller 28 controls the device to run automatically according to the set parameters, repeating the above loading and reciprocating motion thousands or even tens of thousands of times to simulate long-term use conditions. After the test, the traction rope is removed from the device, and its wear, elongation and tensile strength and other performance indicators are measured and analyzed by professional testing equipment to evaluate its durability.

[0029] It should be specifically noted that in the specific implementation of this technical solution, after the test, the traction rope is removed from the device and can be equipped with conventional equipment such as microscopes, elongation measuring instruments, or universal testing machines to measure and analyze its wear, elongation, tensile strength, and other performance indicators, thereby assessing its durability. Although such testing equipment is not described in detail in this technical solution, it is a device that can be routinely selected by those skilled in the art based on actual testing needs. Its usage follows well-known techniques in the field and does not affect the implementation of the core innovation of this solution. In practical applications, this type of equipment is mainly used for quantitative performance analysis of the traction rope after the simulation test, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0030] It should be further noted that in the specific implementation of this technical solution, the controller can be configured with conventional control units such as PLCs, microcontrollers, or microprocessors found in existing technologies. Although these control units are not described in detail in the technical solution, they are components that those skilled in the art can routinely select based on actual automation control needs. Their control logic follows well-known techniques in the field, primarily controlling the start / stop, forward / reverse rotation, and running time of the motor through preset programs or by receiving external commands, thereby achieving the directional rotation and automatic reversing of the reciprocating screw, driving the clamping mechanism and traction rope to complete a preset number of reciprocating cycles. The specific implementation of this control logic can be adjusted according to production requirements, all of which fall within the reasonable extension range of this technical solution and do not affect the implementation of the core innovations of this solution.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
