Description

Technical Field

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

[0002] After the train is manufactured, it usually needs to be hoisted before the running test. At the same time, the train is installed under the conditions of elevated roads and deep valleys and mountains. Hoisting is an existing feasible technical solution. During these hoisting operations, in order to avoid damage to the load, braided rigging is generally used for hoisting operations.

[0003] When the braided rigging is used to hoist the train carriage, two crossbeams are usually used to fix and limit the bottom of the train, and then the braided rigging is used to hoist the two ends of the crossbeam. However, when the hoisting operation is carried out in high altitude and mountainous terrain environments, the humidity in the air is usually high in these terrain areas, and the temperature difference between morning and evening changes greatly. These will have a certain impact on the use strength of the braided rigging. In addition, the braided rigging requires precise operation and control during the hoisting operation of the train carriage. It is difficult to achieve precise balance control when the train carriage is lowered at both ends, which can easily cause equipment damage or accidents. When placing the train carriage on the track, one end is usually installed into the track first, and then the other end is installed into the track. In this process, the center of gravity of the train will be instantly shifted, causing the strip edge of the braided rigging on one end to be compressed and worn, which has higher requirements on the use strength of the braided rigging.

[0020] Example, see Figures 1 to 9 , a strength testing device for sling braided rigging, comprising a mounting base 1 and a protective shell 2 for testing the strength of the braided rigging, a control air pump 6 is connected to the back side wall of the protective shell 2, and a simulation component for simulating the use environment of the braided rigging is connected to the output end of the control air pump 6; Furthermore, the top of the mounting base 1 is fixedly connected to the bottom of the protective shell 2 through the base, the front side wall of the protective shell 2 is rotatably connected to the glass door 4 through the hinge 3, the simulation component is composed of a focusing cover 7 and a plurality of electric heating wires 8, the control air pump 6 is fixedly connected to the protective shell 2 through the focusing cover 7, the inner side wall of the focusing cover 7 is fixedly connected to the electric heating wire 8, the end of the focusing cover 7 is fixedly connected to a mesh cover 9, and the protective shell 2 is fixedly provided with a plurality of sprayers 10 at the inner side wall below the mesh cover 9, wherein the glass door 4 can prevent the braided rigging from breaking during the test process and causing damage to the observer after closing, and can also simulate various use environments in the future, creating a relatively sealed space state; It should be noted that: when simulating various usage environments, the multiple heating wires 8 are first powered on for heating, and then the control air pump 6 is started to generate airflow into the focusing cover 7. After the hot airflow is formed after being heated by the heating wires 8 and enters the protective shell 2, the temperature in the protective shell 2 rises rapidly, simulating the use state of the braided rigging under high temperature conditions. Then, the power supply and heating of the heating wires 8 are stopped, and the multiple sprayers 10 are turned on to spray water mist. The water mist will quickly dissipate in the protective shell 2 along with the airflow of the control air pump 6, so that the temperature in the protective shell 2 drops rapidly, simulating the use state of the braided rigging in some terrain scenes with large temperature differences, and simultaneously maintaining a high humidity air state; The above benefits are as follows: the heating wire 8 and the sprayer 10 can be turned on alternately to simulate the use of the braided rigging in different environments, so that the subsequent change detection is more in line with the actual use situation, and the detection result is more reasonable and reliable; The top of the protective housing 2 is fixedly connected with a sealing plate 5, the bottom of the sealing plate 5 is connected with two relative hydraulic cylinders 11, the output end of the hydraulic cylinder 11 is connected with a suspension rod 14 through an inverted U seat 12, the top of the mounting pedestal 1 is fixedly connected with four electric control rails 15 through a base, the four electric control rails 15 are arranged opposite to each other in pairs, the electric control rails 15 are slidably connected with an adjustment lifting seat 17 through a sliding seat 16, the side wall of the adjustment lifting seat 17 is provided with an arc guide groove, the inner side wall of the arc guide groove is respectively connected with two semicircular detection rods 19 through two semicircular guide plates 18, and the outer side wall of the semicircular detection rod 19 is fixedly connected with three docking limit plates 20; Furthermore, sliding holes are provided on the opposite side walls of the inverted U-seated seat 12, the inner side walls of the sliding holes are slidably connected to the suspension rod 14, the outer side wall of the inverted U-seated seat 12 is fixedly connected to the threaded sleeve 13, the inner side wall of the threaded sleeve 13 is threadedly connected to the end of the suspension rod 14, and a distance sensor for measuring displacement change is provided on the inverted U-seated seat 12, the inner side wall of the arc-shaped guide groove on the adjusting lifting seat 17 is slidably connected to the semicircular guide plate 18, the semicircular guide plate 18 is fixedly connected to the semicircular detection rod 19, three docking limit plates 20 are provided at both ends of the semicircular detection rod 19, and the number of the docking limit plates 20 close to one end of the semicircular guide plate 18 is two, and the side wall of the docking limit plate 20 is a rough surface; It should be noted that: the suspension rod 14 is spirally rotated in the threaded sleeve 13 so that the suspension rod 14 moves outward, 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 opposite direction to reset, so as to complete the limit of one end of the braided rigging. Then, the two adjustment lifting seats 17 are controlled to slide to both sides on the electric control guide rail 15 through the slide seat 16, so that the combined semicircular detection rods 19 are separated, and then the other end of the braided rigging is sleeved on the two combined semicircular detection rods 19, and then the semicircular detection rods 19 are docked and reset to complete the limit of the other end of the braided rigging. Then, the glass door 4 is rotated to close. In the 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 seat 12 will record the displacement change of the hydraulic cylinder 11 during the stretching process. This is a prior art and will not be described in detail, so as to detect whether the elongation of the braided rigging under tension is qualified. The above advantages are: in this way, the movement and change of the suspension rod 14 and the semicircular detection rod 19 can be used to quickly complete the limit of the two ends of the braided rigging, so as to facilitate the subsequent rapid completion of the detection process of whether the elongation of a single braided rigging after stretching is qualified, so that the detection efficiency is higher; The semicircular detection rod 19 is provided with a receiving groove between two butt-jointed limit plates 20 on one end near the semicircular guide plate 18, and a plurality of damage detection components for detecting the surface state of the braided rigging after stretching are arranged in the receiving groove; Further, a docking rod 21 is fixedly connected to the docking limit plate 20 on one side, and a plurality of grooves are provided on the docking rod 21. The inner end surface of the groove is fixedly connected to the limit bead 23 through the telescopic rod 22. A docking groove adapted to the docking rod 21 is provided on the docking limit plate 20 on the other side, and a limit groove adapted to the limit bead 23 is provided on the inner side wall of the docking groove. The damage detection component is composed of an electric control rotating seat 24 and a Velcro winding roller 27. The inner side wall of the storage groove on the semicircular detection rod 19 is fixedly connected to the electric control rotating seat 24. The inner side wall of the electric control rotating seat 24 is rotatably connected to the steering shaft 25. The outer side wall of the steering shaft 25 is fixedly connected to the Velcro winding roller 27 through two bending rods 26. Among them, after the docking rod 21 enters the docking groove, the limiting bead 23 is pressed to compress the telescopic rod 22. When the limiting bead 23 moves to the limiting groove, it extends into the limiting groove under the action of the telescopic rod 22 to complete the docking limit.

[0021] It should be noted that: when simulating the detection of the state of four braided rigging lifting trains, the two semicircular guide plates 18 are slid in the arc guide grooves respectively, and the semicircular guide plates 18 are fixed and limited after sliding to the two ends of the arc guide grooves, and then the two adjusting lifting seats 17 are moved away, and then the end of the braided rigging to be tested is sleeved between the two docking limit plates 20 close to the semicircular guide plates 18, and the other end is sleeved on the outer wall of the suspension rod 14 in the inverted U seat 12. During the tensile test, the height of the adjusting lifting seat 17 is kept consistent to simulate the state of train lifting, and then the height of the adjusting lifting seat 17 on one side is kept unchanged, and the height of the adjusting lifting seat 17 on the other side is reduced. The hydraulic cylinder 11 on this side keeps decreasing synchronously, but the tensile force increases to simulate the state of the train lifting and falling off the track. The braided rigging on the side with the lower height will tilt and rub against the rough surface of the docking limit plate 20. After the simulation is completed, multiple braided rigging are allowed to The synchronous tensioning state is maintained for subsequent inspections. The electric control rotating seat 24 is started to drive the steering shaft 25 to rotate, and the Velcro winding roller 27 is rotated out of the storage groove through the bending rod 26. In the process of the Velcro winding roller 27 rotating out, it will contact the sleeve joint of the end of the woven rigging, and the Velcro winding roller 27 will adhere to the woven rigging, and the adhesion strength between the worn side of the woven rigging and the Velcro winding roller 27 will be greater than that of the unworn side (the smooth and flat surface of the woven rigging usually cannot provide enough friction for the Velcro, resulting in loose adhesion and easy falling off, while the Velcro hook structure will grab the fibers of the worn part of the woven rigging to form a strong bond), so that the resistance generated by the Velcro winding roller 27 rotating outward is different, and then the rotation resistance is measured by the electric control rotating seat 24 to detect the wear resistance of the woven rigging. In this process, the lower end of the woven rigging is sleeved between two docking limit plates 20 near the semicircular guide plate 18 (such as Fig. 9 shown); Based on the above advantages, the separation change of the semicircular detection rod 19 can be used to simulate the state of the train when installing the rail, and the resistance change of the Velcro roller 27 can be used to detect whether the wear resistance of the braided rigging is qualified during the simulation test process; When the present invention is in use, the suspension rod 14 is spirally rotated in the threaded sleeve 13 so that the suspension rod 14 moves outward, 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 opposite direction to reset, so as to complete the position limiting of one end of the braided rigging. Then, the two adjustment lifting seats 17 are controlled to slide to both sides on the electric control guide rail 15 through the slide seat 16, so that the combined semicircular detection rods 19 are separated, and then the other end of the braided rigging is sleeved on the two combined semicircular detection rods 19, and then the semicircular detection rods 19 are docked and reset, so as to complete the The other end of the braided rigging is limited, and then the glass door 4 is turned and closed. In an undisturbed state, the two hydraulic cylinders 11 are synchronously started to stretch the braided rigging. At this time, the distance measuring sensor on the inverted U seat 12 will record the displacement change of the hydraulic cylinder 11 during the stretching process. This is a prior art and will not be described in detail. In this way, it is possible to detect whether the elongation of the braided rigging under tension is qualified. In this way, the movement change of the suspension rod 14 and the semicircular detection rod 19 can be used to quickly complete the limit of the two ends of the braided rigging, which is convenient for the subsequent rapid completion of the detection process of whether the elongation of a single braided rigging after stretching is qualified, making the detection efficiency higher; After the basic detection is completed, when simulating various usage environments, firstly, multiple heating wires 8 are powered on for heating, and then the control air pump 6 is started to generate airflow into the focusing cover 7. After the heating wires 8 are heated to form a hot air flow and enter the protective shell 2, the temperature in the protective shell 2 rises rapidly, simulating the use state of the braided rigging under high temperature conditions. Then, the power-on heating of the heating wires 8 is stopped, and multiple sprayers 10 are turned on to spray water mist. The water mist will quickly dissipate in the protective shell 2 along with the airflow of the control air pump 6, so that the temperature in the protective shell 2 drops rapidly, simulating the use state of the braided rigging in some terrain scenes with large temperature differences, and simultaneously maintaining a high-humidity air state. In this way, the alternating opening of the heating wires 8 and the sprayers 10 can be used to simulate the use state of the braided rigging in different environments, so that the subsequent various change detections are more in line with the actual use conditions, and the detection results are more reasonable and reliable. When simulating the detection of the status of four braided rigging hoisting trains (such as Figure 8The two semicircular guide plates 18 are slid in the arc guide grooves respectively, and fixed and limited after the semicircular guide plates 18 slide to the two ends of the arc guide grooves, and then the two adjusting lifting seats 17 are moved away, and then the end of the braided rigging to be tested is sleeved between the two docking limit plates 20 close to the semicircular guide plates 18, and the other end is sleeved on the outer wall of the suspension rod 14 in the inverted U seat 12. During the tensile test, the height of the adjusting lifting seat 17 is kept consistent to simulate the state of train hoisting. Then, the height of the adjusting lifting seat 17 on one side is kept unchanged, and the height of the adjusting lifting seat 17 on the other side is reduced. The hydraulic cylinder 11 on this side is kept synchronously reduced, but the tensile force is increased to simulate the state of train hoisting and falling off the track. The braided rigging on the side with lower height will tilt and rub against the rough surface of the docking limit plate 20. After the simulation is completed, multiple braided rigging are kept in a synchronous tensioned state to proceed. For subsequent inspection, the electric-controlled rotating seat 24 is started to drive the steering shaft 25 to rotate, and the Velcro winding roller 27 is rotated out of the storage groove through the bending rod 26. In the process of rotating out of the Velcro winding roller 27, it will contact the sleeve joint of the end of the woven rigging, and the Velcro winding roller 27 will adhere to the woven rigging, and the adhesion strength between the worn side of the woven rigging and the Velcro winding roller 27 will be greater than that of the unworn side (the smooth and flat surface of the woven rigging usually cannot provide enough friction for the Velcro, resulting in loose adhesion and easy falling off, while the Velcro hook structure will grab the fibers of the worn part of the woven rigging to form a strong bond), so that the resistance generated by the Velcro winding roller 27 when rotating out is different, and then the rotation resistance is measured by the electric-controlled rotating seat 24 to detect the wear resistance of the woven rigging. In this process, the lower end of the woven rigging is sleeved between two docking limit plates 20 near the semicircular guide plate 18 (such as Fig. 9 The position shown in the figure) can be used to simulate the state of the train when it is installed on the rails by using the separation change of the semicircular detection rod 19, and then the wear resistance change of the Velcro roller 27 can be used to detect whether the wear resistance of the braided rigging is qualified during the simulation test.
