Description

Technical Field

[0001] This utility model relates to an ultrasonic testing device, specifically, to an ultrasonic testing device for truss lifting equipment. Background Technology

[0002] Truss lifting equipment is a type of lifting machinery that uses a truss structure as its core load-bearing component. It lifts and transports workpieces. During long-term use, under the load of the lifted workpieces, the truss beams, legs, and other parts of the truss lifting equipment are prone to bending, cracking, or even breakage, especially in stress concentration areas such as welds and joints. To promptly detect internal damage, workers use ultrasonic testing devices to inspect the internal components. However, due to the height of the truss lifting equipment, workers need to climb onto the truss beams to inspect them. Existing protective structures are insufficient to effectively protect workers inspecting the beams, increasing both the operational risks and labor costs. Therefore, we propose an ultrasonic testing device for truss lifting equipment. Utility Model Content

[0003] The purpose of this invention is to provide an ultrasonic testing device for truss lifting equipment to solve the problems mentioned in the background art, such as increased operational risks and rising labor costs for workers when inspecting truss beams.

[0004] To address the aforementioned problems, the present invention aims to provide an ultrasonic testing device for truss lifting equipment, comprising a testing mechanism for testing truss beams and workpieces. The testing mechanism includes an ultrasonic testing device located below the truss beam. A moving component is provided between the ultrasonic testing device and the truss beam. The moving component drives the ultrasonic testing device to move along the axial direction of the truss beam. When the ultrasonic testing device needs to test a workpiece or truss beam, the moving component rotates the ultrasonic testing device, changing its operating direction. The testing mechanism also includes a moving base and a transmission component. The transmission component connects the moving component and the moving base, driving the moving component to move. The moving component then drives the ultrasonic testing device to move along the axial direction of the truss beam, enabling the ultrasonic testing device to test the truss beam or workpiece.

[0005] As a further improvement to this technical solution, the interior of the truss beam is provided with an inverted U-shaped mounting groove. Both ends of the mounting groove penetrate the bottom of the truss beam. The movable seat is located inside the mounting groove and moves along the axial direction of the mounting groove. The two ends of the movable seat are symmetrically provided with moving grooves. The L-shaped plate is installed through the moving groove, so that the L-shaped plate moves along the axial direction of the moving groove.

[0006] As a further improvement to this technical solution, the moving component includes two L-shaped plates, each L-shaped plate having a horizontal section and a vertical section. One end of the horizontal section of the L-shaped plate is slidably inserted into the interior of the moving groove. The vertical section of the L-shaped plate is downwardly positioned and fixedly connected to a connecting frame. The connecting frame is located below the truss beam. The ultrasonic testing equipment is installed through the two connecting frames, allowing the ultrasonic testing equipment to rotate between the two connecting frames.

[0007] As a further improvement to this technical solution, the ultrasonic testing device is rotatably connected between two connecting frames, and a first motor that drives the ultrasonic testing device to rotate around an axis connected to the connecting frame is installed on one of the connecting frames. The output shaft of the first motor rotates and drives the ultrasonic testing device to rotate. A detection probe is provided on one side of the ultrasonic testing device to change the working direction of the detection probe on the ultrasonic testing device.

[0008] As a further improvement to this technical solution, two horizontally arranged limiting rollers are rotatably connected to the vertical section of the L-shaped plate. Limiting grooves are formed on the two side walls of the mounting groove near the two L-shaped plates along the axis of the mounting groove. The limiting rollers roll along the axis of the limiting grooves, and the limiting grooves support the limiting rollers, so that the limiting rollers support the L-shaped plate and prevent the L-shaped plate from descending during the use of the ultrasonic testing equipment. A second motor is fixedly connected to the horizontal section of one of the L-shaped plates. The output shaft of the second motor is coaxially connected to one of the limiting rollers through a coupling. The output shaft of the rotating second motor drives the limiting roller to rotate, and the limiting roller drives the L-shaped plate to move along the axis of the limiting groove during the rotation.

[0009] As a further improvement to this technical solution, two vertically arranged support rollers are rotatably connected to the horizontal section of the L-shaped plate. The support rollers roll in contact with the inner wall of the mounting groove, supporting the L-shaped plate and the movable seat, leaving a gap between the L-shaped plate and the movable seat and the inner wall of the mounting groove. This prevents the L-shaped plate and the movable seat from contacting the inner wall of the mounting groove during movement, which would increase the friction between the L-shaped plate and the movable seat and the inner wall of the mounting groove. This would easily cause the limiting rollers to slip during rotation, affecting the movement of the L-shaped plate and the movable seat.

[0010] As a further improvement to this technical solution, the transmission assembly includes a transmission screw threaded inside the L-shaped plate. The end of the transmission screw away from the L-shaped plate passes through the L-shaped plate and is rotatably connected to the inside of the moving groove through a bearing. During rotation, the transmission screw drives the L-shaped plate to move along the axial direction of the moving groove, adjusting the distance between the two L-shaped plates so that the limiting roller on the L-shaped plate and the inner wall of the limiting groove are in close contact. This increases the friction between the limiting roller and the inner wall of the limiting groove during rotation and reduces the probability of the limiting roller slipping during rotation.

[0011] As a further improvement to this technical solution, the internal coaxial bearing of the movable seat is rotatably connected to a rotating rod. The end of the rotating rod near the transmission screw is coaxially fixedly connected to a second bevel gear. The second bevel gear meshes with two first bevel gears coaxially fixedly connected to one end of the two transmission screws. During the rotation of the rotating rod, the second bevel gear is driven to rotate, and the rotating second bevel gear drives the first bevel gear and the transmission screw 24 to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This truss lifting equipment uses an ultrasonic testing device. When it is necessary to inspect the truss beam, the moving component drives the ultrasonic testing device to move along the axis of the truss beam, allowing the ultrasonic testing device to inspect the truss beam without requiring workers to climb onto the truss beam, thus reducing the operational risks for workers and reducing labor costs. At the same time, when the truss lifting equipment lifts the workpiece, the moving component drives the ultrasonic testing device to rotate, so that the ultrasonic testing device's working direction is towards the workpiece. The ultrasonic testing device detects whether there is any damage inside the workpiece, thereby obtaining information on the condition of the workpiece and the truss, ensuring the normal use of the workpiece and the truss.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1 - Figure 5 As shown, the purpose of this embodiment is to provide an ultrasonic testing device for truss lifting equipment, including a testing mechanism 2. The testing mechanism 2 is used to test the truss beam 1 and the workpiece. The truss beam 1 has an inverted U-shaped mounting groove 11 inside, and both ends of the mounting groove 11 penetrate the bottom of the truss beam 1, as shown. Figure 1 and Figure 2 As shown, the part inside the mounting groove 11 is fixedly connected by fixing plates located at both ends of the truss beam 1. The detection mechanism 2 includes an ultrasonic testing device 21. The ultrasonic testing device 21 is equipped with an ultrasonic testing instrument for detecting workpieces. A detection probe is provided on one side of the ultrasonic testing device 21. The detection probe and the ultrasonic testing instrument are electrically connected. During the use of the ultrasonic testing device 21, the ultrasonic testing instrument emits ultrasonic waves towards the object to be detected through the detection probe, and at the same time receives the ultrasonic wave signal reflected by the object. The ultrasonic testing instrument analyzes the received ultrasonic wave signal to enable the ultrasonic testing device 21 to detect the object. The use of ultrasonic testing instruments is a mature technology, and it will not be described in detail here.

[0017] The ultrasonic testing device 21 is located below the truss beam 1. A moving component is provided between the ultrasonic testing device 21 and the truss beam 1. The moving component is used to drive the ultrasonic testing device 21 to move along the axis of the truss beam 1. When the ultrasonic testing device 21 needs to test the workpiece or the truss beam 1, the moving component drives the ultrasonic testing device 21 to rotate, changing the working direction of the ultrasonic testing device 21. The testing mechanism 2 also includes a moving base 22 and a transmission component. The moving base 22 is slidably disposed inside the mounting groove 11. The movable seat 22 moves along the axis of the mounting groove 11. The transmission assembly connects the movable component and the movable seat 22 together. The transmission assembly is used to drive the movable component to move. The ultrasonic testing equipment 21 is installed below the truss beam 1 through the movable seat 22, the transmission assembly and the movable component. When it is necessary to test the truss beam 1 or the workpiece, the ultrasonic testing equipment 21 is moved by the movable component to test the truss beam 1 or the workpiece, so that the workers do not need to climb onto the truss beam 1 to perform the operation, thereby reducing the operation risk of the workers and reducing labor costs.

[0018] refer to Figure 4 and Figure 5 The movable base 22 has symmetrically provided movable slots at both ends. The movable assembly includes two L-shaped plates 23, each with a horizontal and a vertical section. The vertical section is located below the horizontal section. One end of the horizontal section of the L-shaped plate 23 is slidably inserted into the movable slot. The vertical section of the L-shaped plate 23 is downwardly positioned and fixedly connected to a connecting frame 231, which is located below the truss beam 1. The ultrasonic testing device 21 is rotatably connected between the two connecting frames 231. One of the connecting frames 231 is equipped with a device that drives the ultrasonic testing device 21 to rotate around the truss beam 1. The first motor 232, which is connected to the axis of the connecting frame 231, rotates. The first motor 232 is a motor whose output shaft can rotate in both directions. The output shaft of the first motor 232 is coaxially connected to one end of the connecting rod through a coupling. The rotating output shaft of the first motor 232 drives the ultrasonic testing equipment 21 to rotate, thereby changing the working direction of the ultrasonic testing equipment 21 and pointing the detection probe on the ultrasonic testing equipment 21 toward the truss beam 1 or the workpiece. This allows the ultrasonic testing equipment 21 to emit and receive ultrasonic signals to detect the truss beam 1 and the workpiece.

[0019] Two horizontally arranged limiting rollers 234 are rotatably connected to the vertical section of the L-shaped plate 23. Limiting grooves 12 are formed on the two side walls of the mounting groove 11 near the two L-shaped plates 23 along the axis of the mounting groove 11. One side of the limiting roller 234 is rolled in the limiting groove 12. The limiting roller 234 rolls along the axis of the limiting groove 12 and is supported by the limiting groove 12, so that the limiting roller 234 supports the L-shaped plate 23 and prevents one end of the L-shaped plate 23 from sagging and contacting the inner wall of the mounting groove 11 during use. This ensures the normal movement of the L-shaped plate 23 and extends the service life of the L-shaped plate 23. When the limiting roller 234 moves in the direction of the limiting groove 12, the limiting roller 234 is in close contact with the inner wall of the limiting groove 12. The limiting groove 12 restricts the limiting roller 234 from moving out of its interior, ensuring the supporting effect of the limiting roller 234 on the L-shaped plate 23.

[0020] A second motor 235 is fixedly connected to the horizontal section of one of the L-shaped plates 23. The second motor 235 is a motor whose output shaft can rotate in both directions. The output shaft of the second motor 235 is coaxially connected to one of the limiting rollers 234 via a coupling. The rotating output shaft of the second motor 235 drives the limiting roller 234 to rotate, and the limiting roller 234 drives the detection mechanism 2 to move during the rotation. Two vertically arranged support rollers 233 are rotatably connected to the horizontal section of the L-shaped plate 23. The second motor 235 is installed on one side of the support rollers 233 and is located on one side of the L-shaped plate 23. At the same time, the top of the second motor 235 does not exceed the upper side of the L-shaped plate 23. When the L-shaped plate 23 moves in the mounting groove 11, the second motor 235 will not affect the L-shaped plate 23. The movement of the L-shaped plate 23 is to prevent the second motor 235 from affecting the normal use of the L-shaped plate 23. The support roller 233 rolls in contact with the inner wall of the mounting groove 11. The support roller 233 supports the L-shaped plate 23 and the movable seat 22, leaving a gap between the L-shaped plate 23 and the movable seat 22 and the inner wall of the mounting groove 11. This prevents the L-shaped plate 23 and the movable seat 22 from contacting the inner wall of the mounting groove 11 during movement, thus avoiding mutual friction between the L-shaped plate 23 and the movable seat 22 and the inner wall of the mounting groove 11, which could cause structural damage. At the same time, the L-shaped plate 23 is supported to prevent friction between the L-shaped plate 23 and the movable seat 22, which could affect the movement of the L-shaped plate 23 and the movable seat 22. This makes it easier for the L-shaped plate 23 to move inside the mounting groove 11, thereby ensuring the normal movement of the ultrasonic testing equipment 21 at the bottom of the truss beam 1.

[0021] A support frame 13 is fixedly connected to the bottom of the truss beam 1. A gap is left between the support frame 13 and the bottom of the truss beam 1. The end of the connecting frame 231 away from the L-shaped plate 23 observes the gap and extends outward. The support frame 13 supports the connecting frame 231, increasing the stability of the connecting frame 231 during movement and preventing the connecting frame 231 from falling off during use. At the same time, the support frame 13 covers the end of the mounting groove 11, reducing the area of ​​the end of the mounting groove 11 exposed to the outside world, thereby reducing the entry of external dust into the interior of the mounting groove 11, thus reducing the dust adhering to the inner wall of the mounting groove 11 and affecting the rotation of the support roller 233 and the limiting roller 234.

[0022] refer to Figure 6 The transmission assembly includes two transmission screws 24 threaded into the interior of an L-shaped plate 23. The threads on the two transmission screws 24 are in opposite directions. During rotation, the two L-shaped plates 23 move towards or away from each other through the threaded connection between the threads and the L-shaped plates 23. The end of the transmission screw 24 away from the L-shaped plate 23 passes through the L-shaped plate 23 and is rotatably connected to the interior of the moving slot via a bearing. A rotating rod is rotatably connected to the interior of the moving seat 22 via a bearing. A second bevel gear 242 is coaxially fixed to the end of the rotating rod near the transmission screw 24, and the end of the rotating rod away from the second bevel gear 242 passes through the side wall of the moving seat 22 and is fixed with a knob. The knob can be turned using an electric wrench or other tools. Two first bevel gears 241, coaxially fixedly connected to one end of the two transmission screws 24, mesh on the second bevel gear 242. During the rotation of the rotating rod, the second bevel gear 242 rotates, causing the first bevel gear 241 and the transmission screw 24 to rotate. When the rotating rod rotates, the meshing of the first bevel gear 241 and the second bevel gear 242 causes the transmission screw 24 to rotate along with the rotating rod. During the rotation of the transmission screw 24, the L-shaped plate 23 moves along the axis of the moving groove. Through the movement of the L-shaped plate 23, this device can be applied to truss beams 1 of different sizes, improving the applicability of this device.

[0023] When using this device: The workers installed the movable base 22, the transmission assembly, and part of the movable assembly inside the mounting groove 11. Then, the workers used tools to rotate the knob, which in turn drove the first bevel gear 241 and the transmission screw 24 to rotate. During the rotation, the transmission screw 24 drove the L-shaped plate 23 to move closer to the movable base 22, so that the limiting roller 234 was in close contact with the inner wall of the limiting groove 12. At this time, the workers installed the ultrasonic testing equipment 21 between the two connecting frames 231 and connected the ultrasonic testing equipment 21 to the output shaft of the first motor 232 through a coupling. In the initial state, the ultrasonic testing device 21 is located below the truss beam 1 near the end. When it is necessary to test the truss beam 1 or the workpiece, the output shaft of the first motor 232 rotates and drives the ultrasonic testing device 21 to rotate, so that the working direction of the testing probe on the ultrasonic testing device 21 is towards the truss beam 1 or the workpiece. At this time, the ultrasonic testing device 21 tests the truss beam 1 or the workpiece. At the same time, the output shaft of the second motor 235 rotates, driving the limiting roller 234 to rotate, causing the limiting roller 234 to move along the axis of the limiting groove 12. During the movement, the limiting roller 234 drives the detection mechanism 2 to move along the axis of the truss beam 1. During the movement of the detection mechanism 2, the ultrasonic testing equipment 21 performs all-round detection on the truss beam 1 or the workpiece.
