Description

Technical Field

[0001] This invention relates to the field of webbing abrasion resistance testing technology, specifically a device for testing the abrasion resistance of warehousing and transportation webbing. Background Technology

[0002] As a core flexible load-bearing component for cargo lifting, bundling, and transfer operations, warehouse transport webbing is widely used in warehousing logistics, port loading and unloading, and industrial plant transfer scenarios. Its abrasion resistance directly determines the safety and service life of lifting operations. Unlike ordinary decorative and clothing webbing, warehouse transport webbing is exposed to complex and variable outdoor and warehouse environments for extended periods. It not only needs to withstand continuous tension and friction but also needs to adapt to complex conditions such as alternating temperature and humidity, irregular contact of goods, transportation bumps and impacts, and diverse friction forms. Therefore, it places extremely high demands on the accuracy of condition reproduction and the comprehensiveness of testing dimensions in webbing abrasion resistance testing. Existing warehouse webbing abrasion resistance testing devices generally have a single, fixed functional structure, and can only achieve a single form of constant friction test under normal temperature and dry conditions, which cannot adapt to the complex working conditions of all warehouse transport scenarios.

[0003] Warehousing and logistics operations are characterized by complex environments, including open-air storage, semi-enclosed warehouses, cold chain storage, and the common occurrence of conditions such as the rainy season in the south and low temperatures and frost in the north. Webbing is constantly exposed to extreme temperatures and humidity. Without the ability to simulate these extreme temperatures and humidity conditions, and by completely ignoring the altering effect of temperature and humidity coupling on the abrasion resistance of webbing, core parameters such as abrasion life and wear rate obtained through conventional testing cannot accurately reflect actual performance under complex warehousing environments. Therefore, the test results have extremely low reference value. Furthermore, the lifting and transport of goods subject the webbing to continuous intermittent impacts, causing cumulative micro-damage to the fibers, which, combined with friction, accelerates breakage and failure.

[0004] In summary, there is an urgent need to develop a device for testing the abrasion resistance of warehousing and transportation webbing that can simulate complex environments and multiple working conditions in order to solve the problems existing in the current technology. Summary of the Invention

[0008] Furthermore, the control components include a conductive disk, a return spring, a straight rod, and a conductive ring. The disk is fixedly connected to the conductive disk, the disk is connected to the fixed cylinder through the return spring, the disk is fixedly connected to the straight rod, the straight rod is fixedly connected to the impact block, the straight rod is slidably connected to the conductive ring, and the conductive ring is set in the through groove of the fixed cylinder. The diameter of the conductive disk is smaller than the inner diameter of the through groove of the fixed cylinder.

[0009] Furthermore, the water outlet component includes an electric push rod, a sealed cylinder, a pressure plate, a buffer spring, a water storage cylinder, a water outlet pipe, and a water inlet pipe. The fixed end of the electric push rod is fixedly connected to the irregularly shaped wheel. The electric push rod passes through the sealed cylinder and is rotatably connected to the pressure plate. The sealed cylinder is fixedly connected to the mounting cylinder. The pressure plate is fixedly connected to the buffer spring. The pressure plate is slidably connected to the sealed cylinder. An air vent is opened in the middle of the sealed cylinder to communicate with the outside. A water inlet pipe is provided on the sealed cylinder. A one-way valve is provided in the water inlet pipe. The sealed cylinder is rotatably connected to the water storage cylinder. A water outlet is provided on the sealed cylinder. The water storage cylinder is ductilely connected to the water outlet of the sealed cylinder. A one-way valve is provided in the water outlet of the sealed cylinder. The water storage cylinder is ductilely connected to the friction cylinder through the water outlet pipe. The conductive disc is electrically connected to the electric push rod. Multiple sets of guide holes are evenly provided on the friction cylinder to deliver water from the water outlet pipe to the webbing.

[0010] Furthermore, the mounting cylinder has an arc-shaped groove, and the mounting cylinder is connected to the electric push rod via a detachable bent rod.

[0011] Furthermore, the control unit includes an electric telescopic rod and a guide rail. The mounting cylinder is fixedly connected to the telescopic end of the electric telescopic rod via a connecting rod. The fixed end of the electric telescopic rod is fixedly installed on the guide rail. The guide rail is fixedly installed on the inner wall of the control box. The control box is equipped with a heater and a cooler.

[0012] Furthermore, the clamping components include a push plate, an adjusting rod, and a fixed plate. The push plate is fixedly connected to the adjusting rod, and the adjusting rod is threadedly connected to the fixed plate.

[0013] Furthermore, the fixed plate is fixedly connected to the drive roller, and the drive roller is connected to the test bench via a drive motor.

[0014] Furthermore, the test piece includes a slide rail, a slide table, and a grinding rod. The slide rail is fixedly connected to the test table, the slide table is slidably connected to the slide rail, and both ends of the grinding rod are fixedly connected to the slide table.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the synchronous extension of a straight rod during the disc's movement to push the impact block outward along the outer groove of the friction cylinder, applying a radial impact force to the webbing that continuously slides against the friction cylinder. This replicates the cyclic impact wear caused by the bumps during cargo transport. After the shaped wheel rotates to the position corresponding to the concave section of the disc, the external pushing force disappears, and the return spring rebounds, causing the entire impact component to retract. This reciprocating cycle forms a periodic impact, reproducing the cumulative damage process of the webbing fibers under bumpy conditions. To simulate extreme scenarios such as cargo misalignment and jamming, or continuous impact on the webbing, the rotating motor can be paused, and the protruding section of the shaped wheel can be continuously pressed against the disc to maintain the impact block in the pushed-out state, allowing for constant impact wear resistance tests in a humid environment.

[0016] 2. This invention uses the outward movement of the disc to synchronously drive the displacement of the conductive disc. After traveling to a specified stroke, the conductive disc contacts the conductive ring in the fixed cylinder groove to establish a circuit. The electric push rod is energized and extends, pushing the pressure plate to compress the buffer spring. The pressure plate moves horizontally within the sealed cylinder, and the air vent in the middle of the cylinder balances the internal and external air pressure to ensure smooth sliding. The outward movement of the pressure plate expands the sealed cylinder cavity, creating a negative pressure. Water is drawn from the water tank through the inlet pipe with a one-way valve. After the protruding section of the irregular wheel disengages from the disc, the conductive disc and conductive ring disconnect, the electric push rod is de-energized, and the buffer spring rebounds, pushing the pressure plate back to its original position. The water inside the cylinder is pressurized and sent to the storage cylinder through the outlet with a one-way valve. It is then transported through the outlet pipe to the guide hole of the friction cylinder for uniform seepage, fully wetting the contact webbing, simulating outdoor rain and damp warehouse operating conditions.

[0017] 3. In extreme working conditions where goods cannot be reset after being shifted and the webbing is subjected to constant impact for a long time, this invention can control the rotary motor to stop rotating, so that the protruding section of the irregular wheel remains in contact with the disc, and the impact block remains in an extended position to continuously impact the wet webbing, thereby testing the wear resistance of the webbing under the combined action of constant impact and moisture.

[0018] 4. This invention allows for testing wear resistance under pure sliding friction conditions by removing the detachable bent rod between the mounting cylinder and the electric push rod, so that the webbing only generates stable sliding friction with the surface of the friction cylinder, thereby obtaining wear resistance data under pure sliding friction conditions, further enriching the testing dimensions and applicable scenarios.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-11 As shown, the present invention provides the following technical solution: like Figures 1-3 , Figure 5 , Figure 7 As shown, a device for testing the abrasion resistance of warehousing and transportation webbing includes a test unit 1, a controller, a clamping unit 2, an adjustment unit 3, and a simulation unit 4 inside the adjustment unit 3. Test unit 1 includes a test bench 11, a drive roller 12, and a test piece 13; Clamping unit 2 includes clamping element 21; The regulating unit 3 includes a regulating box 31, a water tank 32, and a regulating control 33; Simulation unit 4 includes an impact component 41, a water outlet component 42, and a control component 43; The drive roller 12 is fixedly connected to the clamping member 21, the test bench 11 is fixedly connected to the control box 31, and the control device 33 is fixedly connected to the impact member 41.

[0023] The drive roller 12 rotates, causing the webbing to slide on the impact component 41 for wear resistance testing. The control box 31 adjusts the ambient temperature, while the impact component 41, together with the control component 43 and the water outlet component 42, realizes the simulation test under different environments, ensuring that the wear resistance test data of the webbing under different working conditions is more in line with reality.

[0024] like Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, the impact component 41 includes a mounting cylinder 411, a rotary motor 412, a shaped wheel 413, a disc 414, a fixed cylinder 415, a friction cylinder 416, and an impact block 417. The rotary motor 412 is disposed inside the mounting cylinder 411 and is fixedly connected to the shaped wheel 413. The shaped wheel 413 is composed of alternating concave sections and convex sections. The fixed cylinder 415 is fixedly installed inside the mounting cylinder 411 by a connecting rod. The fixed cylinder 415 has a through groove, and a control component 43 is disposed in the through groove of the fixed cylinder 415. The friction cylinder 416 is rotatably mounted on the outer surface of the mounting cylinder 411 and has a rectangular groove. The impact block 417 is slidably connected to the friction cylinder 416.

[0025] like Figure 8 As shown, the control component 43 includes a conductive disk 431, a return spring 432, a straight rod 433, and a conductive ring 434. The disk 414 is fixedly connected to the conductive disk 431. The disk 414 is connected to the fixed cylinder 415 through the return spring 432. The disk 414 is fixedly connected to the straight rod 433. The straight rod 433 is fixedly connected to the impact block 417. The straight rod 433 is slidably connected to the conductive ring 434. The conductive ring 434 is disposed in the through groove of the fixed cylinder 415. The diameter of the conductive disk 431 is smaller than the inner diameter of the through groove of the fixed cylinder 415.

[0026] The controller controls the rotary motor 412 to drive the irregular wheel 413 to rotate continuously. When the protruding section of the irregular wheel 413 rotates to a position relative to the disc 414, it will push the disc 414 to move outward axially. At the same time, it will compress the return spring 432 to store elastic potential energy. This axial displacement is output synchronously through two paths. On the one hand, when the disc 414 moves, it drives the straight rod 433 to move outward synchronously, which in turn pushes the impact block 417 to extend outward along the rectangular groove on the surface of the friction cylinder 416, applying a radial impact force to the webbing that is sliding on the surface of the friction cylinder 416, simulating the vehicle bumping and cargo shaking during transportation. During operation, the webbing is subjected to intermittent impact wear. The impact block 417 is a replaceable structure, and different end face forms such as wedge, rounded corner, and blade shape can be selected according to the test requirements to correspond to the impact effects of different contact scenarios such as angular goods, smooth goods, and sharp-edged goods. When the concave section of the irregular wheel 413 rotates to the position of the disc 414, the axial compressive force disappears, and the return spring 432 releases elastic potential energy to drive the disc 414, the straight rod 433 and the impact block 417 to return to their original positions synchronously, waiting for the next protrusion section to be triggered, thus forming a periodic impact cycle to restore the cumulative effect of impact wear under bumpy conditions.

[0027] like Figure 7 , Figure 9 , Figure 11 As shown, the water outlet component 42 includes an electric push rod 421, a sealed cylinder 422, a pressure plate 423, a buffer spring 424, a water storage cylinder 425, a water outlet pipe 426, and a water inlet pipe 427. The fixed end of the electric push rod 421 is fixedly connected to the irregularly shaped wheel 413. The electric push rod 421 passes through the sealed cylinder 422 and is rotatably connected to the pressure plate 423. The sealed cylinder 422 is fixedly connected to the mounting cylinder 411. The pressure plate 423 is fixedly connected to the buffer spring 424. The pressure plate 423 is slidably connected to the sealed cylinder 422. An air guide hole is opened in the middle of the sealed cylinder 422 to communicate with the outside. A water inlet pipe 427 is provided on the sealed cylinder 422, and a one-way valve is provided inside the water inlet pipe 427. The sealed cylinder 422 is rotatably connected to the water storage cylinder 425. A water outlet is provided on the sealed cylinder 422. The water storage cylinder 425 is conductively connected to the water outlet of the sealed cylinder 422. A one-way valve is provided inside the water outlet of the sealed cylinder 422. The water storage cylinder 425 is conductively connected to the friction cylinder 416 through the water outlet pipe 426. The conductive disk 431 is electrically connected to the electric push rod 421. Multiple sets of guide holes are evenly provided on the friction cylinder 416 to deliver water from the water outlet pipe 426 to the webbing.

[0028] On the other hand, as the disc 414 moves axially, it drives the conductive disc 431 to move synchronously. When the disc 414 moves to the set stroke, the conductive disc 431 contacts and conducts electricity with the conductive ring 434 in the through groove of the fixed cylinder 415. After the control circuit is turned on, the electric push rod 421 is energized and extends, pushing the pressure plate 423 to slide in the sealed cylinder 422. At the same time, the buffer spring 424 is compressed. The sealed cylinder 422 has an air vent in the middle to communicate with the outside, ensuring that the air pressure on both sides is balanced when the pressure plate 423 slides, and the action is smooth. During the process of the pressure plate 423 sliding outward, the volume of the outlet side cavity of the sealed cylinder 422 increases to form a negative pressure. Through the inlet valve with one-way valve, the negative pressure is generated. Water is drawn into the water tank 32 by the water pipe 427. After the protruding section of the irregular wheel 413 leaves the disc 414, the disc 414 retracts under the action of the return spring 432. The conductive disc 431 separates from the conductive ring 434, the electric push rod 421 loses power and loses force, and the buffer spring 424 rebounds to push the pressure plate 423 to reset. The water in the sealed cylinder 422 is pressurized and squeezed into the water storage cylinder 425 through the outlet with a one-way valve. The water is finally transported to the guide hole of the friction cylinder 416 through the outlet pipe 426 and slowly seeps out, evenly wetting the surface of the webbing in contact with the surface of the friction cylinder 416, simulating the working condition of the webbing with water friction in rainy weather and open-air humid environment.

[0029] When it is necessary to simulate extreme working conditions such as goods being unable to return to their original position after being shifted and the webbing being subjected to constant impact for a long period of time, the rotary motor 412 can be controlled to stop rotating, so that the protruding section of the irregular wheel 413 remains in contact with the disc 414, and the impact block 417 remains in an extended position to continuously impact the wet webbing, thereby testing the wear resistance of the webbing under the combined action of constant impact and moisture.

[0030] like Figure 9 As shown, the mounting cylinder 411 has an arc-shaped groove, and the mounting cylinder 411 is connected to the electric push rod 421 through a detachable bent rod.

[0031] If only the wear resistance under pure sliding friction needs to be tested, the detachable bent rod between the mounting cylinder 411 and the electric push rod 421 can be removed, so that the webbing only produces stable sliding friction with the surface of the friction cylinder 416, and the wear resistance data under pure sliding friction conditions can be obtained, further enriching the test dimensions and applicable scenarios.

[0032] like Figure 10 As shown, the control box 33 includes an electric telescopic rod 331 and a guide rail 332. The mounting cylinder 411 is fixedly connected to the telescopic end of the electric telescopic rod 331 via a connecting rod. The fixed end of the electric telescopic rod 331 is fixedly installed on the guide rail 332. The guide rail 332 is fixedly installed on the inner wall of the control box 31. A heater and a cooler are provided on the control box 31.

[0033] By controlling the extension length of the electric telescopic rod 331, the entire simulation unit 4 can be driven to rise and fall vertically, changing the contact wrap angle between the webbing and the friction cylinder 416, thereby adjusting the tension stress inside the webbing and realizing wear resistance comparison tests under different tension levels. If the electric telescopic rods 331 on both sides are controlled to output different extension lengths, the friction cylinder 416 can be tilted axially, allowing the webbing to bear additional torsional torque during the sliding process. This simulates the actual stress state of the webbing twisting and tilting during the warehousing and hoisting of goods and the transfer process, improving the matching degree between the test conditions and the on-site use scenarios.

[0034] The control box 31 is equipped with an independent heater and cooler, which can precisely control the ambient temperature inside the box 31. With the humidification function, it can construct a variety of typical storage environments such as high temperature and high humidity, low temperature and humidity, and normal temperature and dryness, so as to obtain test data that are closer to the actual use scenario.

[0035] like Figure 4 As shown, the clamping member 21 includes a push plate 211, an adjusting rod 212 and a fixing plate 213. The push plate 211 is fixedly connected to the adjusting rod 212, and the adjusting rod 212 is threadedly connected to the fixing plate 213.

[0036] like Figure 3 , Figure 4 As shown, the fixed plate 213 is fixedly connected to the drive roller 12, and the drive roller 12 is connected to the test bench 11 through the drive motor.

[0037] like Figure 2 As shown, the test piece 13 includes a slide rail 131, a slide table 132 and a grinding rod 133. The slide rail 131 is fixedly connected to the test table 11, the slide table 132 is slidably connected to the slide rail 131, and both ends of the grinding rod 133 are fixedly connected to the slide table 132.

[0038] Before testing, the webbing sample is clamped and its initial state is calibrated. One end of the webbing is placed on the surface of the drive roller 12. The adjusting rod 212 on the fixed plate 213 is rotated to drive the push plate 211 to feed towards the roller surface, pressing the webbing tightly against the drive roller 12 to achieve a secure end fixation. The other end of the webbing passes through the control box 31, passes around the grinding rod 133 of the test piece 13, and is suspended by a counterweight. The counterweight provides the initial tension to the webbing. Before testing, the installation height of the slide table 132 on the slide rail 131 can be adjusted. The wrapping angle of the webbing is adjusted by changing the vertical position of the grinding rod 133 to calibrate the initial tension. After clamping and calibration, the controller starts the drive motor, which drives the drive roller 12 to perform reciprocating oscillating motion, pulling the webbing to slide back and forth continuously on the friction contact surface, thereby conducting basic abrasion resistance tests under normal temperature and dry conditions.

[0039] Working principle of the invention: When the equipment is running, the controller drives the rotary motor 412 to drive the irregular wheel 413 to rotate continuously. The irregular wheel 413 has alternating protruding sections and concave sections. When the protruding section is in contact with the disc 414, it will push the disc 414 to move outward axially and compress the reset spring 432 to accumulate elastic force. The axial displacement generated by the disc 414 synchronously triggers two linkage actions.

[0040] On one hand, during the movement of the disc 414, the straight rod 433 extends outward synchronously, pushing the impact block 417 outward along the outer groove of the friction cylinder 416, applying radial impact force to the webbing that continuously slides against the friction cylinder 416, replicating the cyclic impact wear caused by the bumps during cargo transportation. After the shaped wheel 413 rotates to the position of the concave section corresponding to the disc 414, the external pushing force disappears, and the return spring 432 rebounds, causing the entire impact component to retract. The reciprocating cycle forms a periodic impact, restoring the process of cumulative damage to the webbing fibers under bumpy conditions. If it is necessary to simulate the extreme scenario of cargo shifting and jamming, and the webbing being continuously impacted, the rotating motor 412 can be paused, and the protruding section of the shaped wheel 413 can be continuously pressed against the disc 414 to keep the impact block 417 in the ejected state, and a constant impact wear resistance test can be carried out in a humid environment.

[0041] On the other hand, the outward movement of the disc 414 synchronously drives the displacement of the conductive disc 431. After traveling to the specified stroke, the conductive disc 431 contacts the conductive ring 434 in the groove of the fixed cylinder 415 to conduct the circuit. The electric push rod 421 is energized and extends to push the pressure plate 423 to squeeze the buffer spring 424. The pressure plate 423 moves horizontally in the sealed cylinder 422. The air guide hole in the middle of the cylinder balances the internal and external air pressure to ensure smooth sliding. The pressure plate 423 moves outward, causing the cavity of the sealed cylinder 422 to expand and form a negative pressure. Water is drawn from the inside of the water tank 32 through the water inlet pipe 427 with a one-way valve. After the protruding section of the irregular wheel 413 disengages from the disc 414, the conductive disc 431 and the conductive ring 434 are disconnected. The electric push rod 421 is de-energized, and the buffer spring 424 rebounds to push the pressure plate 423 to reset. The water inside the cylinder is pressurized and sent into the water storage cylinder 425 through the water outlet with a one-way valve. Then, it is transported to the guide hole of the friction cylinder 416 through the water outlet pipe 426 and seeps out evenly, fully wetting the contact webbing, simulating the working conditions of open-air rain and damp warehouse.

[0042] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
