Description

Technical Field

[0001] This utility model relates to the field of X-ray inspection equipment for power transmission lines, specifically to a position adjustment mechanism for X-ray inspection of power transmission conductors. Background Technology

[0002] In non-destructive testing of power equipment, the location of the X-ray machine is a core factor determining the quality of the test.

[0003] Since X-ray inspection of power transmission lines is usually carried out on-site while they are in operation, the placement of X-ray machines is quite limited. Furthermore, the power transmission lines and electrical equipment such as tension clamps on the lines may obstruct each other, making it impossible for X-ray inspection to achieve effective imaging and thus obtain effective inspection images.

[0004] Since the location of the X-ray machine directly affects image parameters such as image clarity, contrast, and distortion, providing a qualified X-ray emission location for the X-ray machine has become an urgent problem to be solved in the field of X-ray inspection equipment for power transmission lines. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies in X-ray inspection of power transmission lines, which suffer from insufficient adjustment flexibility of the X-ray machine, resulting in inaccurate X-ray images. This invention provides a position adjustment mechanism for X-ray inspection of power transmission lines. By adjusting the lifting and rotation of the X-ray machine mounted on the X-ray platform, the adjustable range of the X-ray emission direction is increased, thereby effectively expanding the X-ray inspection range. During the X-ray inspection process, the irradiation position and angle can be adjusted more flexibly.

[0006] The objective of this utility model is mainly achieved through the following technical solutions: An X-ray machine position adjustment mechanism for X-ray inspection of power transmission lines includes a X-ray platform, a X-ray mounting frame fixed on the X-ray platform, an X-ray machine rotatably connected to the X-ray mounting frame, and a rotary motor for driving the X-ray machine to rotate circumferentially mounted on the X-ray mounting frame; The radiation emission port of the radiation machine is located on the side of the radiation machine and can rotate circumferentially with the radiation machine; A lifting and adjusting assembly is fixed to the ray platform. One end of the lifting and adjusting assembly is fixed to the outside, and the other end is fixed to the ray platform.

[0007] Currently, in the process of non-destructive testing of power transmission lines, the X-ray inspection equipment is usually erected by hoisting equipment or by using drones. When conducting X-ray inspection on power transmission lines, a detector and an X-ray machine are required. The X-ray machine emits X-rays that form images on the detector to obtain X-ray inspection pictures. The X-ray inspection pictures can be used to effectively determine the health status of the power transmission lines and the fittings on them. Especially when conducting X-ray inspection on tension clamps, it is necessary to flexibly adjust the X-ray inspection range to obtain sufficiently accurate X-ray inspection images.

[0008] The X-ray inspection of tension clamps is subject to interference from other factors such as obstruction or drainage clamps, which can affect the X-ray inspection results. Therefore, in order to effectively obtain the X-ray inspection results of tension clamps, the detector and X-ray machine need to be adjusted to adapt to the position of the tension clamps for accurate X-ray inspection.

[0009] Based on this, the position of the X-ray machine is extremely important in the X-ray detection process. However, the adjustment of the X-ray emission position in the prior art is quite limited. This is because the X-ray machine in the prior art is usually mounted on the transport equipment by side mounting. Therefore, the X-ray emission direction is limited to side lifting and / or rotation. This will affect the X-ray irradiation range to a certain extent. In practical applications, if there is partial obstruction on the transmission line or if the positions of tension clamps and drainage clamps are difficult to distinguish, the X-ray detection results will be inaccurate.

[0010] This invention connects to the outside world via a lifting and adjusting assembly, enabling effective connection to a transport vehicle, drone, or other carrier equipment. The external carrier equipment provides overall support for this invention, and the position of the X-ray machine can be adjusted accordingly. Since the lifting and adjusting assembly can place the entire invention below the power transmission line, and the rotation angle can be adjusted to achieve a wide range of X-ray emission direction, and the X-ray emission port is located on the side of the X-ray machine, the X-ray platform and the lifting and adjusting assembly do not affect the X-ray emission direction.

[0011] This invention, through the lifting adjustment component and the rotation drive of the rotating motor, enables the emission direction of the X-ray machine's X-ray emission port to be effectively adjusted within a spatial range, thereby effectively aligning with the position to be detected and cooperating with the detector to complete X-ray detection.

[0012] Furthermore, the radiation support frame includes a motor support frame and a balance support frame, and a body support frame is erected between the motor support frame and the balance support frame. One side of the body support frame is rotatably connected to the motor support frame, and the opposite side is rotatably connected to the balance support frame. The rotating motor is mounted on the motor support frame, and the output shaft of the rotating motor is connected to the side of the machine body support frame.

[0013] In this invention, the motor support frame and the balance support frame form an overhead structure, allowing the machine body support frame to rotate circumferentially within the overhead space. When the drive motor drives the machine body support frame to rotate, it can drive the X-ray machine to rotate. The X-ray machine can effectively maintain its own stability on the machine body support frame, thereby enabling the X-rays to be emitted stably.

[0014] Furthermore, a rotating end is provided between the motor support frame and the machine body support frame. One end of the rotating end is fixedly connected to the motor support frame, and the other end is rotatably connected to the machine body support frame. The output shaft of the rotating motor passes through the rotating end and is connected to the machine body support frame.

[0015] In this invention, the rotating end can provide rotation space for the output shaft of the rotating motor, and can avoid affecting the rotation of the machine body support frame while stably connecting the motor support frame and the machine body support frame.

[0016] Furthermore, a stabilizing bearing is provided between the balance support frame and the body support frame. One end of the stabilizing bearing is fixed to the balance support frame, and the other end is fixed to the body support frame. The body support frame can rotate circumferentially around the axis of the stabilizing bearing.

[0017] When the machine body support frame rotates, the stability of the support frame can be effectively maintained during the rotation process by the limiting of the stabilizing bearing.

[0018] Furthermore, the side of the balance support frame is provided with a stabilizing reinforcing plate, one side of which is fixed to the balance support frame and the other side is fixed to the ray platform.

[0019] In this invention, the stabilizing reinforcing plate is used to enhance the load-bearing capacity of the balance support frame, thereby improving the erection stability of the Shudie X-ray platform and the balance support frame.

[0020] Furthermore, the lifting and adjusting assembly includes a lifting telescopic frame, the upper end of which is fixed with a rope winch, and the lower end of which is fixed to the ray platform; The lifting telescopic frame can extend downwards naturally, and the rope winch is used to wind up the lifting telescopic frame.

[0021] In this invention, the lifting telescopic frame in the lifting adjustment assembly can effectively control the position of the X-ray platform by extending or retracting, thereby changing the height of the X-ray machine. The rope winch retracts the lifting telescopic frame by winding it, and the lifting telescopic frame can extend downwards using its own weight.

[0022] Furthermore, the lifting telescopic frame includes a load-bearing connecting frame, which is fixed to the outside environment, and the rope winch is fixed on the load-bearing connecting frame; An outer frame is fixed below the bearing connecting frame, and several sets of overlapping sliding connecting frames are sequentially sleeved inside the outer frame. A driving sliding connecting frame is sleeved inside the overlapping sliding connecting frame. The outer frame is slidably connected to the overlapping sliding connecting frame, two adjacent overlapping sliding connecting frames are slidably connected, and the driving sliding connecting frame is slidably connected to the overlapping sliding connecting frame. The bottom of the drive sliding connecting frame is fixed with a connecting seat, which is fixed to the ray platform. A pulley assembly is fixed on the connecting seat, and the pulley assembly is connected to the rope winch as a movable pulley.

[0023] In this invention, the supporting connecting frame is used to connect with external equipment. The rope winch is fixed on the supporting connecting frame, thus occupying the top position of the lifting and telescopic frame, which facilitates the retraction control of the lifting and telescopic frame. The outer frame body is used for the overall support of the telescopic part. The length of the lifting and telescopic frame is extended by the sequential sliding of the overlapping sliding connecting frame. The driving sliding connecting frame is used to connect the connecting seat and uses a pulley assembly to combine the pulley assembly and the rope winch into a movable pulley. By winding the rope, the position of the pulley assembly can be effectively raised, thereby driving the connecting seat body to rise. During the lifting process, the driving sliding connecting frame and the overlapping sliding connecting frame will retract sequentially, driving the X-ray platform to rise, and the height of the X-ray machine will also rise.

[0024] Furthermore, the rope winch includes a winch ladder, a rope is wound around the winch body, the rope winch includes a winch body, a rope is wound around the winch body, a side frame is provided on the side of the winch body, and the side frame is fixed to the outer frame body; A drive motor is mounted on the side frame, and the output shaft of the drive motor is connected to the winch reel body. The winch reel body is rotatably connected to the side frame. The pulley assembly includes a fixed frame, which is mounted and fixed on the connecting base. The pulley body is installed inside the fixed frame, and the rope, the pulley body and the winch disc form a movable pulley connection.

[0025] In this utility model, the side frame is used to support the drive motor and the winch disc body. The winch disc body rotates to achieve the purpose of winding or unwinding the rope. The drive motor is used to drive the rotation of the winch disc body. The fixing frame of the pulley assembly is used to support the pulley body and provide the force bearing of the movable pulley connection when action occurs.

[0026] Furthermore, the outer frame includes two fixed side plates, and a first side plate connecting rod is provided between the fixed side plates. The two ends of the first side plate connecting rod are respectively fixed to the two fixed side plates. The overlapping sliding connecting frame is located between the two fixed side plates. A fixed limiting end is fixed to the bottom inner side of the fixed side plate. The overlapping sliding connecting frame is slidably connected to the fixed limiting end. The drive sliding connection frame includes two load-bearing side plates, and a central side plate connecting rod is provided between the load-bearing side plates. The two ends of the central side plate connecting rod are respectively fixed to the two load-bearing side plates. Each of the bearing side plates is fixed with a second sliding rail on the side near the overlapping sliding connection frame, and the second sliding rail is slidably connected to the overlapping sliding connection frame.

[0027] In this invention, the fixed side plate and the first side plate connecting rod form an integral frame structure with the outer frame body. Similarly, the driving sliding connecting frame also forms a frame structure using the bearing side plate and the central side plate connecting rod. With the overlapping sliding connecting frame sleeved in the outer frame body and the driving sliding connecting frame sleeved in the overlapping sliding connecting frame, the driving sliding connecting frame can drive the overlapping sliding connecting frame to slide down sequentially and extend to the required length when it descends to the bottom of the overlapping sliding connecting frame. When the rope winch winds up the rope, it can also drive the overlapping sliding connecting frame to rise sequentially by pulling the driving sliding connecting frame. This allows the invention to effectively control the height position of the X-ray platform, achieving the purpose of adjusting the height of the X-ray machine. Furthermore, during this process, the X-ray detection range can be more flexibly adjusted to change the X-ray emission position, thereby improving the effectiveness of the X-ray detection results.

[0028] Furthermore, the overlapping sliding connecting frame includes two sliding side plates, and a second side plate connecting rod is provided between the two sliding side plates. The two ends of the second side plate connecting rod are respectively fixed to the two sliding side plates. Each sliding side plate is fixed with a first sliding track on the side closest to the outer frame, and each sliding side plate is fixed with a sliding limit end on the side closest to the drive sliding connecting frame. The first sliding track is slidably connected to the fixed limiting end or the sliding limiting end of the adjacent overlapping sliding connecting frame; The sliding limit end is slidably connected to the first sliding rail or the second sliding rail of the adjacent overlapping sliding connecting frame.

[0029] In this utility model, the two sliding side plates in the overlapping sliding connecting frame are connected by the second side plate connecting rod to form a frame structure, which can effectively maintain the overall stability during the overlapping process. The first sliding rail provides the sliding stroke of the overlapping sliding connecting frame, and the second sliding rail provides the sliding stroke of the overlapping sliding connecting frame or the driving sliding connecting frame. The sliding limiting end can realize the sliding of the overlapping sliding connecting frame and / or the telescopic driving sliding connecting frame by sliding connection with the first sliding rail or the second sliding rail, thereby using the sliding stroke to complete the extension or retraction of the lifting telescopic frame. The fixed limiting end is fixed in position and can bear and guide the overall lifting telescopic frame during the extension or retraction of the overlapping sliding connecting frame.

[0030] In summary, the present invention has the following advantages compared with the prior art: This invention uses an external support device to support the entire invention, and on this basis, the position of the X-ray machine is adjusted. Since the lifting and adjusting component can place the entire invention below the power transmission line, and combined with the adjustment of the rotation angle, a wide range of X-ray emission direction can be adjusted. The X-ray emission port is located on the side of the X-ray machine, so that the X-ray platform and the lifting and adjusting component will not affect the X-ray emission direction.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] Example: like Figures 1-4 As shown, this embodiment relates to a position adjustment mechanism for an X-ray machine 5 for X-ray inspection of power transmission lines, including an X-ray platform 4. The X-ray platform 4 is characterized in that an X-ray mounting frame 6 is fixed on the X-ray platform 4, an X-ray machine 5 is rotatably connected to the X-ray mounting frame 6, and a rotary motor 3 for driving the X-ray machine 5 to rotate circumferentially is installed on the X-ray mounting frame 6. The radiation emission port 51 of the radiation machine 5 is located on the side of the radiation machine 5 and can rotate circumferentially with the radiation machine 5; A lifting and adjusting assembly is fixed on the X-ray platform 4. One end of the lifting and adjusting assembly is fixed to the outside, and the other end is fixed to the X-ray platform 4.

[0034] In this embodiment, the height of the X-ray platform 4 is adjusted using a lifting and adjusting component. Once the height is adjusted, the rotation of the rotary motor 3 drives the rotation of the X-ray machine 5, thereby adjusting the X-ray emission port 51 to a suitable position. The rotation and lifting adjustments of the X-ray machine 5 can be performed synchronously, allowing the X-ray emission direction of the machine 5 to be adjusted in real time as needed, changing the irradiation range and position of the X-ray detection, thus making the X-ray detection results more accurate.

[0035] The radiation support frame 6 includes a motor support frame 61 and a balance support frame 64. A body support frame 63 is erected between the motor support frame 61 and the balance support frame 64. One side of the body support frame 63 is rotatably connected to the motor support frame 61, and the opposite side is rotatably connected to the balance support frame 64. The rotating motor 3 is mounted on the motor support frame 61, and the output shaft of the rotating motor 3 is connected to the side of the machine body support frame 63.

[0036] A rotating end 62 is provided between the motor support frame 61 and the body support frame 63. One end of the rotating end 62 is fixedly connected to the motor support frame 61, and the other end is rotatably connected to the body support frame 63. The output shaft of the rotating motor 3 passes through the rotating end 62 and is connected to the body support frame 63.

[0037] A stabilizing bearing 8 is provided between the balance support frame 64 and the body support frame 63. One end of the stabilizing bearing 8 is fixed to the balance support frame 64, and the other end is fixed to the body support frame 63. The body support frame 63 can rotate circumferentially around the axis of the stabilizing bearing 8.

[0038] The side of the balance support frame 64 is provided with a stabilizing reinforcing plate 7. One side of the stabilizing reinforcing plate 7 is fixed to the balance support frame 64, and the other side is fixed to the radiation platform 4.

[0039] The lifting adjustment assembly and the rotation drive of the rotating motor 3 enable the emission direction of the X-ray machine 5's X-ray emission port 51 to be effectively adjusted within the spatial range, thereby effectively aligning with the position to be detected and cooperating with the detector to complete the X-ray detection.

[0040] The motor support frame 61 and the balance support frame 64 form an overhead structure, which allows the body support frame 63 to rotate circumferentially in the overhead space. When the drive motor 13 drives the body support frame 63 to rotate, it can drive the X-ray machine 5 to rotate. The X-ray machine 5 can effectively maintain its own stability on the body support frame 63, so that the X-rays can be emitted stably.

[0041] In this embodiment, the stabilizing bearing 8 and the rotating end 62 are both used to stabilize the rotation state of the X-ray machine 5 and can effectively avoid the safety risks of instability of the machine body support frame 63 during rotation, thereby achieving the purpose of protecting the X-ray machine 5 and avoiding the harmful risks of accidental radiation exposure during X-ray detection.

[0042] The lifting and adjusting assembly includes a lifting telescopic frame 2, with a rope winch 1 fixed to the upper end of the lifting telescopic frame 2 and the lower end of the lifting telescopic frame 2 fixed to the ray platform 4. The lifting telescopic frame 2 can extend downwards naturally, and the rope winch 1 is used to wind up the lifting telescopic frame 2.

[0043] In this embodiment, the rope winch 1 on the lifting telescopic frame 2 controls the retraction of the lifting telescopic frame 2 by winding the rope when it rotates.

[0044] The lifting telescopic frame 2 includes a load-bearing connecting frame 21, which is fixed to the outside, and the rope winch 1 is fixed on the load-bearing connecting frame 21. An outer frame 22 is fixed below the bearing connecting frame 21. Several sets of overlapping sliding connecting frames 24 are sequentially sleeved inside the outer frame 22. A driving sliding connecting frame 25 is sleeved inside the overlapping sliding connecting frame 24. The outer frame 22 is slidably connected to the overlapping sliding connecting frame 24, two adjacent overlapping sliding connecting frames 24 are slidably connected, and the driving sliding connecting frame 25 is slidably connected to the overlapping sliding connecting frame 24; The bottom of the drive sliding connecting frame 25 is fixed with a connecting seat 28, which is fixed to the ray platform 4. A pulley assembly is fixed on the connecting seat 28, and the pulley assembly is connected to the rope winch 1 as a movable pulley.

[0045] In practical applications, the load-bearing connecting frame 21 is fixed to the outside to achieve a stable connection with the transport equipment.

[0046] When it is necessary to control the X-ray machine 5 to rise, the rope winch 1 rewinds and drives the drive sliding connecting frame 25 to rise. The drive sliding connecting frame 25 rises and squeezes the overlapping sliding connecting frame 24 to rise, thereby forming the overall contraction of the lifting telescopic frame 2. The connecting seat 28 rises and drives the X-ray mounting frame 6 to rise, thereby raising the position of the X-ray machine 5. When it is necessary to lower the height of the X-ray machine 5, the rope winch 1 is loosened. Under the weight of the X-ray machine 5, the X-ray mounting frame 6, and the drive sliding connecting frame 25, the lifting telescopic frame 2 extends downward as a whole, thereby achieving the purpose of lowering the height of the X-ray machine 5.

[0047] In this embodiment, the height adjustment of the X-ray machine 5 is mainly achieved by the interaction of the self-weight of the corresponding components and the winding of the rope winch 1. The overlapping sliding connecting frame 24 in this embodiment is used to maintain the stability of the telescopic trajectory and limit the telescopic range of the lifting telescopic frame 2, so as to avoid the X-ray machine 5 from shaking or other unstable factors during operation, which would lead to unqualified X-ray detection results.

[0048] The rope winch 1 includes a winch body 11, on which a rope is wound. A side frame 12 is provided on the side of the winch body 11, and the side frame 12 is fixed to the outer frame 22. A drive motor 13 is mounted on the side frame 12. The output shaft of the drive motor 13 is connected to the winch disc body 11. The winch disc body 11 is rotatably connected to the side frame 12. The pulley assembly includes a fixing frame 27, which is mounted and fixed on the connecting seat 28. A pulley body 26 is installed inside the fixing frame 27. The rope, the pulley body 26, and the winch disc 11 form a movable pulley connection.

[0049] In this embodiment, the rope winch 1 achieves the winding effect on the drive sliding connecting frame 25 by rotating the rope around the winch body 11. The side frame 12 is used to keep the rotation of the winch body 11 relatively independent. The drive motor 13 is used to drive the winch body 11 to rotate. The fixing frame 27 provides installation space for the pulley body 26. The movable pulley formed by the pulley body 26, the rope, and the winch body 11 can effectively control the actual height of the connecting seat 28 by controlling the rope release length.

[0050] If both ends of the rope are wound onto the winch disc 11, then two winch discs 11 can be set up and the two ends of the rope can be wound up respectively, thereby increasing the speed of the lifting pulley body 26. If only one end of the rope is wound onto the winch disc 11, the other end can be fixed to the bearing connecting frame 21 or the outer frame 22, forming a movable pulley with unilateral movement on the pulley body 26. Since the overlapping sliding connecting frame 24 restricts the extension and retraction trajectory of the lifting telescopic frame 2, the pulley body 26, the rope, and the winch disc 11 can be used to effectively complete the lifting of the connecting seat 28.

[0051] The outer frame 22 includes two fixed side plates 222, and a first side plate connecting rod 221 is provided between the fixed side plates 222. The two ends of the first side plate connecting rod 221 are respectively fixed to the two fixed side plates 222. The overlapping sliding connecting frame 24 is located between the two fixed side plates 222. The inner bottom of the fixed side plate 222 is fixed with a fixed limiting end 223. The overlapping sliding connecting frame 24 is slidably connected to the fixed limiting end 223. The drive sliding connection frame 25 includes two bearing side plates 252, and a central side plate connecting rod 253 is provided between the bearing side plates 252. The two ends of the central side plate connecting rod 253 are respectively fixed to the two bearing side plates 252. Each of the bearing side plates 252 near the overlapping sliding connection frame 24 is fixed with a second sliding rail 251, and the second sliding rail 251 is slidably connected to the overlapping sliding connection frame 24.

[0052] The overlapping sliding connecting frame 24 includes two sliding side plates 243, and a second side plate connecting rod 244 is provided between the two sliding side plates 243. The two ends of the second side plate connecting rod 244 are respectively fixed to the two sliding side plates 243. Each sliding side plate 243 is fixed with a first sliding rail 241 on the side near the outer frame 22, and each sliding side plate 243 is fixed with a sliding limiting end 242 on the side near the drive sliding connecting frame 25. The first sliding track 241 is slidably connected to the fixed limiting end 223 or the sliding limiting end 242 of the adjacent overlapping sliding connecting frame 24; The sliding limiting end 242 is slidably connected to the first sliding rail 241 or the second sliding rail 251 of the adjacent overlapping sliding connecting frame 24.

[0053] In this embodiment, the two sliding side plates 243 in the overlapping sliding connecting frame 24 are connected by the second side plate connecting rod 244 to form a frame structure, which can effectively maintain overall stability during the overlapping process. The first sliding rail 241 provides the sliding stroke of the overlapping sliding connecting frame 24, and the second sliding rail 251 provides the sliding stroke of the overlapping sliding connecting frame 24 or the driving sliding connecting frame 25. The sliding limiting end 242 can realize the sliding of the overlapping sliding connecting frame 24 and / or the telescopic driving sliding connecting frame 25 by sliding connection with the first sliding rail 241 or the second sliding rail 251, thereby using the sliding stroke to complete the extension or retraction of the lifting telescopic frame 2. The fixed limiting end 223 is fixed in position and can bear and guide the overall lifting telescopic frame 2 during the extension or retraction of the overlapping sliding connecting frame 24.

[0054] The two sliding side plates 243 in the overlapping sliding connecting frame 24 are connected by the second side plate connecting rod 244 to form a frame structure, which can effectively maintain the overall stability during the overlapping process. The first sliding rail 241 provides the sliding stroke of the overlapping sliding connecting frame 24, and the second sliding rail 251 provides the sliding stroke of the overlapping sliding connecting frame 24 or the driving sliding connecting frame 25. The sliding limiting end 242 can realize the sliding of the overlapping sliding connecting frame 24 and / or the telescopic driving sliding connecting frame 25 by sliding connection with the first sliding rail 241 or the second sliding rail 251, thereby using the sliding stroke to complete the extension or retraction of the lifting telescopic frame 2. The fixed limiting end 223 is fixed in position and can bear and guide the overall lifting telescopic frame 2 during the extension or retraction of the overlapping sliding connecting frame 24.

[0055] When the lifting telescopic frame 2 raises the connecting seat 28: when the overlapping sliding connecting frame 24 slides on the outer frame 22, the driving sliding connecting frame 25 is lifted upward by sliding within the sliding limit end 242 via the second sliding rail 251 when the connecting seat 28 is raised. When the driving sliding connecting frame 25 slides to the point where the second sliding rail 251 is restricted, the sliding limit end 242 is pushed up and slides upward along the first sliding rail 241. Subsequently, the overlapping sliding connecting frames 24 sleeved on the outside are raised in sequence until the first sliding rail 241 of the outermost overlapping sliding connecting frame 24 is restricted at the fixed limit end 223, and the retraction action of the lifting telescopic frame 2 stops.

[0056] In this embodiment, both the drive motor 13 and the X-ray machine 5 are models that can be mass-produced in the prior art, thereby enabling this embodiment to be mass-produced.
