Description

Technical Field

[0001] This utility model belongs to the field of cable tray testing technology, specifically relating to a steel cable tray processing and fracture testing device. Background Technology

[0002] In modern industrial and construction sectors, cable trays serve as crucial support and protection structures for power and communication lines. Their safety and stability directly impact the operational efficiency and security of the entire system. Therefore, cable tray inspection is of paramount importance, serving not only as a key step in accident prevention but also as an effective means of extending service life. Cable tray inspection methods include visual inspection, non-destructive testing (NDT) techniques, and electrical testing. NDT techniques, such as ultrasonic testing and magnetic particle testing, can detect hidden problems like internal cracks and defects without damaging the cable tray structure.

[0003] Existing steel cable tray processing and fracture testing devices typically use magnetic particle testing equipment to attract magnetic particles through a magnetic field to reveal the location and shape of cracks. Before testing, magnetic suspension liquid needs to be sprayed onto the surface of the cable tray. However, since the magnetic suspension liquid contains specific chemical components, such as surfactants, penetrants, and developers, the gases generated during spraying can be harmful to human health. Furthermore, the magnetic suspension liquid needs to be carried and used separately for each test, which takes up a lot of space and causes inconvenience to the work. Utility Model Content

[0004] The purpose of this invention is to provide a steel cable tray processing and testing device that can directly inject magnetic suspension liquid into the storage tank without the need for an additional magnetic suspension liquid container, thus saving space. During testing, the magnetic suspension liquid can be sprayed out through a nozzle. The straight cylinder can prevent the sprayed gas from escaping, while the gas is absorbed and filtered by a DC fan and a filter layer. The sliding of the sealing plate can also control the suction state of the DC fan, thereby preventing the magnetic suspension liquid gas from causing harm to human health.

[0007] A spray switch is fixedly assembled on one side of the handle, and the spray switch and the nozzle form a pneumatic connection inside the liquid storage tank.

[0008] The handle is electrically connected to the DC fan, and the two sides of the support are provided with positioning grooves for the clamping plate to be embedded.

[0009] The sealing plate has a through groove in the middle for movably fitting with the baffle, and a roller is rotatably connected to one end of the through groove.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 , Figures 3-4As shown, a steel cable tray processing and testing device includes a handle 1. A magnetized probe 103 is symmetrically fixedly assembled at the bottom of the handle 1. A liquid storage tank 102 is symmetrically and continuously connected to both sides of the handle 1. A jet switch 101 is fixedly assembled on one side of the handle 1. A nozzle 108 is symmetrically and continuously connected to the bottom of the liquid storage tank 102. The jet switch 101 and the nozzle 108 form a pneumatic connection inside the liquid storage tank 102. A fan shroud 104 is fixedly assembled at the bottom of the liquid storage tank 102, located between the two nozzles 108. A rotating assembly is located inside the fan shroud 104. Equipped with a DC fan 112, the handle 1 is electrically connected to the DC fan 112. A support 109 is fixedly assembled at the bottom of the fan cover 104. A filter layer 111 is symmetrically and movably fitted between the support 109 and the fan cover 104. Clamping plates 105 are symmetrically engaged on both sides of the filter layer 111. Two nozzles 108 form a Y-shaped three-way connection below the support 109. Positioning grooves 110 for clamping plates 105 are opened on both sides of the support 109. A straight cylinder 107 is fixedly connected to the bottom of the support 109 and outside the nozzles 108.

[0023] According to the above structure, magnetic suspension liquid is injected into the storage tank 102. When the handle 1, magnetized probe 103 and other components are powered on, the DC fan 112 is powered on at the same time and starts to rotate and draw air. The magnetized probe 103 and the straight cylinder 107 are placed at the detection position. Pressing the spray switch 101 controls the air valve assembled inside the storage tank 102 to form a high-speed airflow. The airflow sprays the magnetic suspension liquid stored in the nozzle 108 from the bottom of the straight cylinder 107. The two nozzles 108 converge and become one. At this time, the straight cylinder 107 covers the outside of the nozzle 108. One end of the straight cylinder 107 is in contact with the detection area. The straight cylinder 107 forms a relatively sealed space to prevent gas leakage. At the same time, the DC fan 112 rotates to draw the gas in the straight cylinder 107 upward. The molecules in the gas are filtered and removed by the filter layer 111. The filter layer 111 can be removed and replaced by disassembling the clamp 105. The support 109 is used to support and place the filter layer 111.

[0024] See attached document Figures 1-5A baffle 106 is symmetrically fixedly connected to the inner wall of the straight cylinder 107 on both sides of the nozzle 108. A through slot 121 is symmetrically opened through both sides of the straight cylinder 107 and on both sides of the baffle 106. A sealing plate 118 is slidably connected to the inner wall of the through slot 121. A through slot 122 is opened through the middle of the sealing plate 118 for movably engaging with the baffle 106. A roller 123 is rotatably connected to one end of the through slot 122. An elastic telescopic mechanism for controlling the sliding of the sealing plate 118 is assembled on both sides of the straight cylinder 107. The elastic telescopic mechanism includes a fixing plate 113 fixedly installed on both sides of the straight cylinder 107. The bottom of the fixing plate 113... The cylindrical tube 107 is symmetrically and elastically assembled with large spring columns 114. The bottom of the two large spring columns 114 is fixedly connected to the connecting plate 115. The elastic telescopic mechanism also includes wedge plates 116 symmetrically and slidingly assembled on both sides of the cylindrical tube 107. One end of the wedge plate 116 passes through the through groove 122 and is fixedly connected to the connecting plate 115. The bottom of the wedge plate 116 is fixedly connected to the connecting column 117. One end of the sealing plate 118 is fixedly connected to the connecting plate 119. Small spring columns 120 are symmetrically and elastically assembled on both sides of the wedge plate 116 on the outer wall of the cylindrical tube 107. One end of the small spring column 120 is fixedly connected to the connecting plate 119.

[0025] According to the above structure, when the magnetized probe 103 and the straight cylinder 107 are placed at the detection location, the connecting post 117 contacts the area being detected in advance and is compressed upwards. The connecting post 117 drives the wedge plate 116 to move upwards, and the large spring post 114 retracts accordingly. As the wedge plate 116 moves, it gradually reduces its obstruction to the through slot 122. The connecting plate 119, under the influence of the tension of the small spring post 120, begins to drive the sealing plate 118 to slide into the straight cylinder 107. The two sealing plates... After 118 is embedded in the straight cylinder 107, the slot 122 fits into the baffle 106. The baffle 106 and the sealing plate 118 form an isolation plate inside the straight cylinder 107 and outside the nozzle 108, sealing off most of the flow space. Only some gaps remain on both sides of the sealing plate 118. This prevents the DC fan 112 from drawing too much or accidentally drawing the magnetic suspension liquid that has just been sprayed onto the test piece when the nozzle 108 is spraying. The gas generated by the spray can still pass through the sealing plate 118 and... The gap between the straight cylinders 107 is removed. When the magnetized probe 103 and the straight cylinder 107 are removed from the tested object, the connecting post 117 is no longer compressed. The connecting plate 115 and the wedge plate 116 are rebounded by the elastic force of the large spring post 114. The wedge plate 116 moves downward, and the inclined surface of the wedge plate 116 presses against the through groove 122, causing the sealing plate 118 to slide out of the straight cylinder 107. The small spring post 120 then rebounds. The setting of the roller 123 lowers the gap between the through groove 122 and the sealing plate 118. The friction force; this utility model can directly inject the magnetic suspension into the storage tank 102 without the need to carry an additional magnetic suspension device bottle, which saves space. During the test, the magnetic suspension can be sprayed out through the nozzle 108. The straight cylinder 107 can prevent the sprayed gas from escaping. At the same time, the gas is absorbed and filtered by the DC fan 112 and the filter layer 111. The sliding of the sealing plate 118 can also control the suction state of the DC fan 112, thereby preventing the magnetic suspension gas from causing harm to human health.

[0026] The working principle of this utility model is as follows: Magnetic suspension is injected into the storage tank 102. When the handle 1, magnetized probe 103, and other components are powered on, the DC fan 112 is simultaneously powered on and begins to rotate and draw air. The magnetized probe 103 and the straight cylinder 107 are placed at the detection location. Pressing the spray switch 101 controls the air valve assembled inside the storage tank 102 to form a high-speed airflow. The airflow sprays the magnetic suspension stored in the nozzle 108 from the bottom of the straight cylinder 107. The two nozzles 108 converge and connect into one, while the straight cylinder 107 covers the outside of this nozzle 108, with one end of the straight cylinder 107 in contact with the object being detected. The straight cylinder 107 forms a relatively sealed space to prevent gas leakage. Simultaneously, the DC fan 112 rotates to draw the gas upwards from the straight cylinder 107. Gas molecules are filtered and removed by the filter layer 111. The filter layer 111 can be removed and replaced by disassembling the clamping plate 105. The support 109 supports and holds the filter layer 111. When the magnetized probe 103 and the straight cylinder 107 are placed at the detection location, the connecting column 117 contacts the area being detected in advance and is compressed upwards. The connecting column 117 drives the wedge plate 116 to move upwards, causing the large spring column 114 to contract accordingly. As plate 116 moves, it gradually reduces its obstruction of slot 122. Connecting plate 119, under the tension of the small spring post 120, begins to slide sealing plate 118 into the straight cylinder 107. After the two sealing plates 118 are embedded in the straight cylinder 107, slot 122 engages with baffle 106. Baffle 106 and sealing plate 118 form an isolation plate inside the straight cylinder 107 and outside the nozzle 108, sealing off most of the flow space. Only gaps remain on both sides of sealing plate 118, thus preventing excessive or accidental drawing of the DC fan 112 during nozzle 108 spraying. The magnetic suspension liquid is sprayed onto the test piece, and the gas generated by the spray can still be extracted through the gap between the sealing plate 118 and the straight cylinder 107. When the magnetized probe 103 and the straight cylinder 107 leave the test piece, the connecting column 117 is no longer squeezed, and the connecting plate 115 and the wedge plate 116 are rebounded by the elastic force of the large spring column 114. The wedge plate 116 moves downward, and the inclined surface of the wedge plate 116 squeezes the through groove 122, causing the sealing plate 118 to slide out of the straight cylinder 107. The small spring column 120 rebounds accordingly. The setting of the roller 123 reduces the friction between the through groove 122 and the sealing plate 118.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
