Description

Technical Field

[0001] The present invention relates to the technical field of braided rigging detection, and particularly to a strength detection device for sling braided rigging. Background Art

[0002] After a train is manufactured, it usually needs to be hoisted before a running test. At the same time, train installation is carried out under the scenario conditions of elevated and deep valley mountainous areas. Hoisting is a feasible existing technical solution. In these hoisting operations, in order to avoid damaging the hoisted object, braided rigging is generally used for hoisting operations.

[0003] When using braided rigging to hoist a train car body, two crossbeams are usually used to fix and limit the position at the bottom of the train, and then the two ends of the crossbeams are hoisted with braided rigging. However, when carrying out hoisting operations in terrain environments such as high places and mountains, due to the relatively high humidity in the air and large temperature differences between morning and evening in these terrain areas, these will all have a certain impact on the service strength of the braided rigging. Moreover, during the process of using braided rigging to hoist a train car body, the hoisting operation requires precise operation and control. It is difficult to achieve precise balance control when lowering the two ends of the train car body together, which is likely to cause equipment damage or accidents. When placing the train car body on the track, usually one end is first installed on the track, and then the other end is installed on the track. During this process, the center of gravity of the train will shift instantaneously, causing the belt edge of the braided rigging on one end to be compressed and worn. This places higher requirements on the service strength of the braided rigging. Therefore, a strength detection device for sling braided rigging is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that during the process of using braided rigging to hoist a train car body in the prior art, the hoisting operation requires precise operation and control. It is difficult to achieve precise balance control when lowering the two ends of the train car body together, which is likely to cause equipment damage or accidents. When placing the train car body on the track, usually one end is first installed on the track, and then the other end is installed on the track. During this process, the center of gravity of the train will shift instantaneously, causing the belt edge of the braided rigging on one end to be compressed and worn, and to provide a strength detection device for sling braided rigging.

[0010] Preferably, sliding holes are formed on the opposite side walls of the inverted U-shaped seat. The inner side wall of the sliding hole is slidably connected to the suspension rod. A threaded sleeve is fixedly connected to the outer side wall of the inverted U-shaped seat. The inner side wall of the threaded sleeve is threadedly connected to the end of the suspension rod. A distance measuring sensor for measuring displacement change is arranged on the inverted U-shaped seat.

[0011] Preferably, the inner side wall of the arc-shaped guide groove on the adjustable lifting seat is slidably connected to the semi-circular guide plate. The semi-circular guide plate is fixedly connected to the semi-circular detection rod. The three docking limit plates are arranged at both ends of the semi-circular detection rod, and the number of them at the end close to the semi-circular guide plate is two. The side wall of the docking limit plate is a rough surface.

[0012] Preferably, a docking rod is fixedly connected to one side of the docking limit plate. A plurality of grooves are formed on the docking rod. The inner end surface of the groove is fixedly connected to a limit bead through a telescopic rod. A docking groove adapted to the docking rod is formed on the other side of the docking limit plate. A limit groove adapted to the limit bead is formed on the inner side wall of the docking groove.

This solution integrates multiple functions such as elongation rate detection, environment simulation, hoisting state simulation, and wear resistance detection, and can complete multiple detections on one device, improving the comprehensiveness and efficiency of the detection.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example, referring to Figures 1 to 9 , a strength detection device for a sling braided rigging, comprising an installation pedestal 1 for testing the strength of the braided rigging and a protective housing 2. A control air pump 6 is connected to the back side wall of the protective housing 2, and the output end of the control air pump 6 is connected to a simulation component for simulating the usage environment of the braided rigging;

[0032] Furthermore, the top end of the installation pedestal 1 is fixedly connected to the bottom end of the protective housing 2 through a base. The front side wall of the protective housing 2 is rotatably connected to a glass door 4 through a hinge 3. The simulation component consists of a converging hood 7 and a plurality of heating wires 8. The control air pump 6 is fixedly connected to the protective housing 2 through the converging hood 7. The inner side wall of the converging hood 7 is fixedly connected to the heating wires 8. A wire mesh cover 9 is fixedly connected to the end of the converging hood 7. A plurality of sprayers 10 are fixedly arranged on the inner side wall of the protective housing 2 below the wire mesh cover 9. Among them, after the glass door 4 is closed, it can prevent the braided rigging from breaking during the test and causing injury to the observers, and also create a relatively sealed space state for subsequent simulation of various usage environments;

[0033] It should be noted that when simulating various usage environments, first, the plurality of heating wires 8 are energized and heated. Subsequently, the control air pump 6 is started to generate air flow into the converging hood 7. After being heated by the heating wires 8 and forming hot air flow into the protective housing 2, the temperature inside the protective housing 2 rises rapidly, simulating the usage state of the braided rigging under high temperature conditions. Subsequently, the power supply to the heating wires 8 is stopped, and a plurality of sprayers 10 are opened to spray water mist. Then, the water mist will quickly disperse inside the protective housing 2 along with the air flow of the control air pump 6, causing the temperature inside the protective housing 2 to drop rapidly, simulating the usage state of the braided rigging in some terrain scenarios with large temperature differences, and simultaneously maintaining a high humidity air state;

[0034] The benefits based on the above are as follows: In this way, the alternating opening of the heating wires 8 and the sprayers 10 can be used to simulate the usage states of the braided rigging in different environments, making the subsequent detection of various changes more in line with the actual usage situation and making the detection results more reasonable and reliable;

[0035] A sealing plate 5 is fixedly connected to the top end of the protective housing 2. Two opposite hydraulic cylinders 11 are connected to the bottom end of the sealing plate 5. The output end of the hydraulic cylinder 11 is connected to a hanging rod 14 through an inverted U-shaped seat 12. Four electric control guide rails 15 are fixedly connected to the top end of the installation pedestal 1 through a base. The four electric control guide rails 15 are arranged in two pairs opposite to each other. The electric control guide rail 15 is slidably connected to an adjustable lifting seat 17 through a sliding seat 16. An arc-shaped guide groove is provided on the side wall of the adjustable lifting seat 17. The inner side wall of the arc-shaped guide groove is respectively connected to two semi-circular detection rods 19 through two semi-circular guide plates 18. Three docking limit plates 20 are fixedly connected to the outer side wall of the semi-circular detection rod 19;

[0036] Further, sliding holes are provided on the opposite side walls of the inverted U-shaped seat 12. The inner side wall of the sliding hole is slidably connected to the hanging rod 14. A threaded sleeve 13 is fixedly connected to the outer side wall of the inverted U-shaped seat 12. The inner side wall of the threaded sleeve 13 is threadedly connected to the end of the hanging rod 14. A distance measuring sensor for measuring displacement change is provided on the inverted U-shaped seat 12. The inner side wall of the arc-shaped guide groove on the adjustable lifting seat 17 is slidably connected to the semi-circular guide plate 18. The semi-circular guide plate 18 is fixedly connected to the semi-circular detection rod 19. The three docking limit plates 20 are arranged at both ends of the semi-circular detection rod 19, and the number of them at the end close to the semi-circular guide plate 18 is two. The side wall of the docking limit plate 20 is a rough surface;

[0037] It should be noted that: Rotate the hanging rod 14 in the threaded sleeve 13 so that the hanging rod 14 moves outwards, thereby separating the two hanging rods 14. At this time, one end of the braided rigging to be tested is sleeved on the outer side wall of the adjacent ends of the two hanging rods 14, and then the two hanging rods 14 are rotated in the reverse direction to reset, completing the limit of one end of the braided rigging. Subsequently, control the two adjustable lifting seats 17 to slide on the electric control guide rails 15 to both sides through the sliding seats 16, so that the combined semi-circular detection rods 19 are separated. Then, the other end of the braided rigging is sleeved on the two combined semi-circular detection rods 19, and then the semi-circular detection rods 19 are docked and reset to complete the limit of the other end of the braided rigging. Subsequently, rotate and close the glass door 4. Under the state of no interference, synchronously start the two hydraulic cylinders 11 to stretch the braided rigging. At this time, the distance measuring sensor on the inverted U-shaped seat 12 will record the displacement change during the stretching process of the hydraulic cylinder 11. This is the prior art and will not be elaborated too much, so as to detect whether the elongation rate of the braided rigging under the tensile state is qualified;

[0038] The benefits based on the above are: In this way, the movement changes of the hanging rod 14 and the semi-circular detection rod 19 can be utilized to quickly complete the limit of both ends of the braided rigging, facilitating the subsequent rapid completion of the detection process of whether the elongation rate of a single braided rigging after stretching is qualified, making the detection efficiency higher;

[0039] A storage groove is provided between the two docking limit plates 20 at the end of the semi-circular detection rod 19 close to the semi-circular guide plate 18. A plurality of damage detection components for detecting the surface state of the braided rigging after stretching are arranged in the storage groove;

[0040] Furthermore, a docking rod 21 is fixedly connected to one side of the docking limit plate 20. A plurality of grooves are formed in the docking rod 21. The inner end surface of the groove is fixedly connected with a limit bead 23 through a telescopic rod 22. A docking groove adapted to the docking rod 21 is formed in the other side of the docking limit plate 20. A limit groove adapted to the limit bead 23 is formed in the inner side wall of the docking groove. The damage detection assembly is composed of an electric control rotating base 24 and a magic tape winding roller 27. The inner side wall of the storage groove on the semi-circular detection rod 19 is fixedly connected with the electric control rotating base 24. A steering shaft 25 is rotatably connected to the inner side wall of the electric control rotating base 24. The outer side wall of the steering shaft 25 is fixedly connected with the magic tape winding roller 27 through two bent rods 26;

[0041] Among them, after the docking rod 21 enters the docking groove, the limit bead 23 will compress the telescopic rod 22 under pressure. When the limit bead 23 moves to the limit groove, it will extend into the limit groove under the action of the telescopic rod 22 to complete the docking limit.

[0042] It should be noted that when simulating the detection of the state of four braided rigging hoisting a train, the two semi-circular guide plates 18 are respectively slid in the arc-shaped guide groove. After the semi-circular guide plates 18 are slid to both ends of the arc-shaped guide groove, they are fixed and limited. Then, the two adjusting lifting seats 17 are moved away. Then, the end of the braided rigging to be tested is sleeved between the two docking limit plates 20 near the semi-circular guide plate 18, and the other end is sleeved on the outer side wall of the suspension rod 14 in the inverted U-shaped seat 12. During the tensile test, first keep the heights of the adjusting lifting seats 17 the same to simulate the state during train hoisting. Then, keep the height of one side of the adjusting lifting seat 17 unchanged, and lower the height of the other side of the adjusting lifting seat 17. The hydraulic cylinder 11 on this side is lowered synchronously, but the tensile force increases to simulate the state when the train hoisting derails. Then, the braided rigging on the side with a lower height will tilt and rub against the rough surface of the docking limit plate 20. After the simulation is completed, at this time, keep the multiple braided riggings in a synchronously tensioned state for subsequent detection. Start the electric control rotating base 24 to drive the steering shaft 25 to rotate, and the magic tape winding roller 27 is rotated out of the storage groove through the bent rod 26. During the process of the magic tape winding roller 27 being rotated out, it will contact the socket part of the end of the braided rigging. Then, the magic tape winding roller 27 will adhere to the braided rigging. The adhesion force between the worn side of the braided rigging and the magic tape winding roller 27 will be greater than that of the non-worn side (the smooth and flat surface of the braided rigging usually cannot provide enough friction for the magic tape, resulting in insecure adhesion and easy detachment. The hook-shaped structure of the magic tape will grab the fibers at the worn part of the braided rigging to form a firm bond), so that the resistance generated by the outward rotation of the magic tape winding roller 27 is different, and then the electric control rotating base 24 measures the rotational resistance to detect the wear resistance of the braided rigging. During this process, the lower end of the braided rigging is sleeved between the two docking limit plates 20 near the semi-circular guide plate 18 (as Figure 9 shown in the position);

[0043] The above-mentioned benefits are as follows: the separation change of the semi-circular detection rod 19 can be utilized to simulate the state when the train installation falls off the track, and the wear resistance of the braided rigging during the simulation detection process can be detected by the resistance change of the magic tape winding out of the roller 27 in the subsequent process;

[0044] When the present invention is in use, the suspension rod 14 is rotated in the threaded sleeve 13 in a spiral manner, so that the suspension rod 14 moves outwards, thereby separating the two suspension rods 14. At this time, one end of the braided rigging to be tested is sleeved on the outer side walls of the adjacent ends of the two suspension rods 14, and then the two suspension rods 14 are rotated in the reverse direction to reset, completing the limitation of one end of the braided rigging. Subsequently, the two adjusting lifting seats 17 are controlled to slide on the electric control guide rail 15 through the sliding seats 16 to both sides, so that the combined semi-circular detection rods 19 are separated. Then, the other end of the braided rigging is sleeved on the two combined semi-circular detection rods 19, and then the semi-circular detection rods 19 are butted and reset, completing the limitation of the other end of the braided rigging. Subsequently, the glass door 4 is rotated and closed. In a state without interference, the two hydraulic cylinders 11 are synchronously started to stretch the braided rigging. At this time, the distance measuring sensor on the inverted U-shaped seat 12 will record the displacement change during the stretching process of the hydraulic cylinder 11. This is the prior art and will not be elaborated too much, so as to detect whether the elongation rate of the braided rigging under the tensile state is qualified. In this way, the movement changes of the suspension rod 14 and the semi-circular detection rod 19 can be utilized to quickly complete the limitation of both ends of the braided rigging, facilitating the subsequent rapid detection process of whether the elongation rate of a single braided rigging after stretching is qualified, and making the detection efficiency higher;

[0045] After the basic detection is completed, when simulating various usage environments, first, a plurality of heating wires 8 are powered on for heating, and then the control air pump 6 is started to generate air flow into the flow focusing hood 7. After being heated by the heating wires 8, the hot air flow enters the protective housing 2, so that the temperature in the protective housing 2 rises rapidly, simulating the usage state of the braided rigging under high temperature conditions. Subsequently, the power supply of the heating wires 8 is stopped, and a plurality of sprayers 10 are opened to spray water mist. Then, the water mist will quickly disperse in the protective housing 2 along with the air flow of the control air pump 6, so that the temperature in the protective housing 2 drops rapidly, simulating the usage state of the braided rigging in some terrain scenarios with large temperature differences, and simultaneously maintaining a high humidity air state. In this way, the alternate opening of the heating wires 8 and the sprayers 10 can be utilized to simulate the usage state of the braided rigging in different environments, making the subsequent various change detections more in line with the actual usage situation and making the detection results more reasonable and reliable;

[0046] When simulating the detection of the state of hoisting a train by four braided riggings (such as Figure 8In the state shown, slide the two semi-circular guide plates 18 in the arc-shaped guide grooves respectively. After the semi-circular guide plates 18 slide to both ends of the arc-shaped guide grooves, fix and limit them. Then move the two adjusting lifting seats 17 away from each other. Next, put the end of the braided rigging to be tested between the two docking limit plates 20 near the semi-circular guide plates 18, and put the other end on the outer wall of the suspension rod 14 in the inverted U-shaped seat 12. During the tensile test, first keep the heights of the adjusting lifting seats 17 the same to simulate the state during train hoisting. Then keep the height of one side of the adjusting lifting seat 17 unchanged, and lower the height of the other side of the adjusting lifting seat 17. The hydraulic cylinder 11 on this side also drops synchronously, but the tensile force increases to simulate the state when the train hoisting derails. Then the braided rigging on the side with a lower height will tilt and rub against the rough surface of the docking limit plate 20. After the simulation is completed, at this time, keep multiple braided riggings in a synchronously tensioned state for subsequent detection. Start the electric control swivel base 24 to drive the steering shaft 25 to rotate, and through the bending rod 26, turn out the magic tape winding roller 27 from the storage groove. During the process of the magic tape winding roller 27 turning out, it will contact the socket part at the end of the braided rigging, so the magic tape winding roller 27 will adhere to the braided rigging. And the adhesion force between the worn side of the braided rigging and the magic tape winding roller 27 will be greater than that of the non-worn side (the smooth and flat surface of the braided rigging usually cannot provide enough friction force for the magic tape, resulting in insecure pasting and easy falling off. And the hook-shaped structure of the magic tape will catch the fibers at the worn part of the braided rigging to form a firm combination), making the resistance generated by the outward rotation of the magic tape winding roller 27 different, and then the electric control swivel base 24 measures the rotational resistance to detect the wear resistance of the braided rigging. During this process, the lower end of the braided rigging is sleeved between the two docking limit plates 20 near the semi-circular guide plates 18 (as Figure 9 shown in the position), so that the separation change of the semi-circular detection rod 19 can be used to simulate the state when the train is installed and derails, and in the subsequent process, through the resistance change of the magic tape winding roller 27 turning out, it is detected whether the wear resistance of the braided rigging is qualified during the simulation test.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
