Description

Technical Field

[0001] This utility model relates to the field of X-ray inspection equipment for power transmission lines, specifically the walking mechanism of an X-ray inspection device for power transmission lines. Background Technology

[0002] Radiographic testing of power transmission lines is an important maintenance task for the safe operation of power transmission lines. Radiographic testing of power transmission lines can effectively reflect the health status of power transmission lines and their various components, thereby enabling equipment maintenance and repair work based on the assessment of the health status of each component.

[0003] When performing X-ray inspection on multi-split conductors, problems such as mutual obstruction between components and limited mobility of the inspection equipment can occur, leading to a low pass rate for X-ray inspection images during continuous X-ray inspection, or even the inability to capture qualified X-ray images.

[0004] Therefore, how to increase the position adjustment capability of the X-ray inspection device in X-ray inspection work 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 where the poor position adjustment capability of X-ray inspection devices leads to a low rate of qualified X-ray images. This invention provides a traveling mechanism for a power transmission line X-ray inspection device. The X-ray inspection device is mounted on a frame structure, and detachable first and second traveling components are supported by first and second limiting rails. Therefore, this invention can adapt to more power transmission lines by adjusting the positions of the first and second traveling components, thereby improving the position adjustment capability of the X-ray inspection device and increasing the rate of qualified X-ray images.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] The traveling mechanism of the X-ray inspection device for power transmission lines includes a support frame, in which the X-ray inspection device is installed. A first limiting rail is fixed on one side of the support frame, and a second limiting rail is fixed on the opposite side.

[0008] The first limiting track and the second limiting track are symmetrically distributed with the center line of the bottom surface of the supporting frame as the center line;

[0009] Several first traveling components are detachably fixed on the first limiting rail, and several second traveling components are detachably fixed on the second limiting rail.

[0010] Currently, when conducting X-ray inspection of power transmission lines, external carrier equipment is typically used to mount the X-ray inspection device. Existing technologies use carrier equipment with fixed spacing, so different specifications of carrier equipment need to be replaced when dealing with different power transmission lines. Moreover, many carrier equipment currently need to be mounted on the side to mount the X-ray inspection device in order to effectively maintain the stability of the X-ray inspection work.

[0011] This invention allows the first and second traveling components to directly contact the power transmission line, enabling them to bear the weight of the supporting frame and the X-ray detection device. Furthermore, both the first and second limiting rails are located on the side of the supporting frame, thus accommodating the X-ray detection device between two traveling support structures. With the X-ray detection device mounted, the center of gravity of this invention remains within the vertical area of ​​the supporting frame. As long as the first and second traveling components can stably rest on the power transmission line, this invention avoids safety risks such as tilting.

[0012] The first limiting track and the second limiting track are symmetrically distributed with the center line of the bottom surface of the supporting frame as the center line. Therefore, this utility model can continuously maintain the balance of the overall equipment during the process of moving on the power transmission line, providing higher stability for X-ray inspection work.

[0013] Since the X-ray detection device is located within the support frame, its movement on the power transmission line and its X-ray detection work are not hindered by factors such as drain clamps or branch conductors on the power transmission line. Furthermore, the flexibility of X-ray irradiation is effectively improved by the frame structure within the support frame. Combined with the position adjustment capabilities of the support frame on the power transmission line by the first and second walking components, the X-ray detection range position adjustment capability of the X-ray detection device can be effectively improved, thereby enhancing the imaging flexibility of X-ray detection and increasing the X-ray detection imaging pass rate.

[0014] Furthermore, the first walking component includes a first wheel bracket, the first wheel bracket is detachably fixed to the first limiting track, and a first walking wheel is mounted on the first wheel bracket;

[0015] The second walking component includes a second wheel bracket, which is detachably fixed to the second limiting rail, and a second walking wheel is mounted on the second wheel bracket;

[0016] The first wheel bracket and the second wheel bracket have the same structure.

[0017] In this utility model, the first wheel bracket and the first limiting track are detachably fixed, so the position of the first wheel bracket on the first limiting track can be adjusted, thereby enabling the first wheel bracket in this utility model to effectively adjust its position according to the actual position of the power transmission line, so that the entire utility model can maintain balance.

[0018] The second wheel bracket and the second limiting track are detachable and fixed, so the position of the second wheel bracket on the second limiting track can be adjusted, thereby enabling the second wheel bracket in this utility model to effectively adjust its position according to the actual position of the power transmission line, so that the entire utility model can maintain balance.

[0019] The first and second wheels are in direct contact with the power transmission line.

[0020] Furthermore, the diameter of the first traveling wheel is larger than the diameter of the second traveling wheel.

[0021] The first traveling wheel has a larger diameter, giving it a stronger obstacle-crossing ability, thus enabling the present invention to have a stronger ability to travel on power transmission lines.

[0022] Furthermore, the second wheel bracket includes a fitting end, which can be nested outside the second limiting rail and detachably fixed to the second limiting rail;

[0023] Several side supports are provided below the fitting end head. The side supports are located on the side of the second traveling wheel and are fixed to the fitting end head. A connecting plate is provided between the several side supports, and the connecting plate is fixedly connected to the side supports.

[0024] In this invention, the interlocking end can improve the stability of the connection between the second wheel bracket and the second limiting track by interlocking with the second limiting track, thus avoiding safety risks during walking. The connection between the first wheel bracket and the first limiting track is similar.

[0025] The side support is used to suspend the second traveling wheel, so that the rotation of the second traveling wheel is not affected, which is beneficial to the overall movement of this utility model on the power transmission line.

[0026] The connecting plate maintains the overall stability of the first wheel body support by connecting to the side bracket, thereby ensuring the stability of the second traveling wheel as it travels on the power transmission line. The same applies to the first wheel body support and the first traveling wheel.

[0027] Furthermore, the connecting plate is provided with several hollow holes.

[0028] In this invention, the hollowed-out holes can prevent the airflow caused by the rotation of the first or second traveling wheel from affecting the walking state of this invention, and can also ensure the normal rotation of the first and second traveling wheels when working at heights.

[0029] Furthermore, a locking assembly is provided on the side of the second wheel bracket, which can abut against or disengage from the power transmission line that is in contact with the wheel surface of the second traveling wheel.

[0030] In this invention, the locking component can stop the entire invention by friction of the power transmission line contacted by the second traveling wheel through a tight contact.

[0031] Furthermore, the locking assembly includes a telescopic rod, one end of which is fixed to the second wheel bracket, and the other end of which is provided with a hinged end. A limit frame is fixed to the side of the second wheel bracket, and the limit frame is hinged to the side of the hinged end. The telescopic rod is hinged to the end of the hinged end.

[0032] An arc-shaped rod is fixed to the other end of the hinged end away from the telescopic rod, and the arc-shaped rod bends and extends toward the second traveling wheel.

[0033] In this utility model, the telescopic rod is used to push the hinged end to rotate, and the limiting frame limits the movement trajectory of the arc-shaped rod to rotate toward the wheel surface of the second traveling wheel by means of the side hinge limiting. The second traveling wheel is stopped by the power transmission wire that contacts the wheel surface of the second traveling wheel with the arc-shaped rod.

[0034] Furthermore, a friction roller is fixed to the end of the arc-shaped rod.

[0035] In this invention, the friction roller stops by pressing against and squeezing the power transmission line, thereby stopping the movement of the entire invention. By controlling the extension and retraction force of the telescopic rod, the squeezing force on the friction roller can be effectively controlled. When the squeezing force is small, the friction roller can help maintain the stability of the overall movement of the invention by rotating.

[0036] Furthermore, the second wheel bracket is provided with a connecting bar on the side near the X-ray detection device, one end of the connecting bar is fixed to the second wheel bracket, and the other end is fixed to the X-ray detection device.

[0037] The connecting bar is used to connect the X-ray detection device and the second wheel bracket, thereby using the X-ray detection device to support the second wheel bracket and effectively improve the load-bearing capacity of the second wheel bracket. In this way, when the locking component is used to stop, the overall braking ability of this utility model can be effectively improved.

[0038] Furthermore, a hanging bracket is fixed to the top of the supporting frame.

[0039] This invention utilizes the aforementioned bracket to transport the entire walking mechanism, thereby enabling the invention to be transported to the corresponding area requiring X-ray detection, thus avoiding the need for the invention to undergo large-scale relocation itself.

[0040] In summary, this utility model has the following advantages compared with the prior art:

[0041] This invention, after incorporating the X-ray inspection device, maintains its center of gravity within the vertical area encompassed by the supporting frame. With the first and second traveling components stably resting on the power transmission line, this invention eliminates safety risks such as lateral tilting. The first and second limiting tracks are symmetrically distributed with the centerline of the bottom surface of the supporting frame as their center line. Therefore, this invention can continuously maintain the overall balance of the equipment during its movement on the power transmission line, providing greater stability for X-ray inspection operations.

[0046] 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.

[0047] Example:

[0048] like Figs. 1-2 As shown, the traveling mechanism of the X-ray inspection device 1 for power transmission lines includes a support frame 3, in which the X-ray inspection device 1 is installed. A first limiting rail 4 is fixed on one side of the support frame 3, and a second limiting rail 7 is fixed on the opposite side.

[0049] The first limiting track 4 and the second limiting track 7 are symmetrically distributed with the center line of the bottom surface of the bearing frame 3 as the center line;

[0050] Several first traveling components are detachably fixed on the first limiting rail 4, and several second traveling components are detachably fixed on the second limiting rail 7.

[0051] Furthermore, a hanging bracket 2 is fixed to the top of the supporting frame 3.

[0052] In practical applications, this embodiment adjusts the positions of the first and second traveling components according to the actual conditions of the power transmission line. Using a hanging frame 2 connected to a drone or crane, the embodiment is lifted above the power transmission line. The first and second traveling components are then placed on the power transmission line. With the support of the power transmission line, the X-ray inspection device 1 effectively performs X-ray inspection on the locations to be inspected. The first and second traveling components transport the carrying frame 3 to each location to be inspected, thus achieving the completion of multiple inspections in a single lifting operation.

[0053] In this embodiment, the first limiting track 4 and the second limiting track 7 are symmetrically distributed with the center line of the bottom surface of the supporting frame 3 as the center line, so that the center of gravity can be controlled within the vertical area of ​​the supporting frame. Therefore, this embodiment can not only use the frame structure of the supporting frame 3 to support the X-ray detection device 1 and increase the irradiable area of ​​the X-ray detection device 1, but also ensure the stability of the walking mechanism as a whole during movement, thereby enhancing the adjustability and imaging stability of X-ray detection in this embodiment and improving the imaging qualification rate of X-ray images.

[0054] In this embodiment, both the X-ray detection device 1 and the telescopic rod 91 are models that can be mass-produced in the prior art, which facilitates large-scale production in this embodiment.

[0055] Furthermore, the first walking component includes a first wheel bracket 5, which is detachably fixed to the first limiting track 4, and a first walking wheel 6 is mounted on the first wheel bracket 5;

[0056] The second walking component includes a second wheel bracket 8, which is detachably fixed to the second limiting rail 7, and a second walking wheel 10 is mounted on the second wheel bracket 8;

[0057] The first wheel bracket 5 and the second wheel bracket 8 have the same structure.

[0058] Furthermore, the diameter of the first traveling wheel 6 is larger than the diameter of the second traveling wheel 10.

[0059] In this embodiment, the first wheel bracket 5 and the second wheel bracket 8 are both adjusted in installation position according to the actual situation of the power transmission line before lifting. Since the first traveling wheel 6 and the second traveling wheel 10 are both used on the power transmission line, the X-ray detection device 1 in this embodiment is located in the area enclosed by the first traveling wheel 6 and the second traveling wheel 10. When performing X-ray detection, it will not affect the normal movement of the first traveling wheel 6 and the second traveling wheel 10, and the various obstacles on the power transmission line will not hinder the movement of this embodiment.

[0060] For example, when there is a drain clamp on the transmission line, during the X-ray inspection of the tension clamp, it is necessary to adjust the position of the X-ray inspection device 1 to avoid the drain clamp. However, the drain clamp will obstruct the movement of the side-mounted X-ray inspection device 1. In this embodiment, the X-ray inspection device 1 is housed in the frame structure by the support frame 3. Based on this, the first traveling wheel 6 and the second traveling wheel 10 will not be obstructed by the drain clamp during the movement, thereby ensuring that the traveling mechanism can smoothly transport the X-ray inspection device 1 to the appropriate position for X-ray inspection.

[0061] Furthermore, the second wheel bracket 8 includes a fitting end 81, which can be nested outside the second limiting rail 7 and detachably fixed to the second limiting rail 7;

[0062] Below the fitting end 81, there are several side brackets 82. The side brackets 82 are located on the side of the second traveling wheel 10 and are fixed to the fitting end 81. A connecting plate 83 is provided between the several side brackets 82. The connecting plate 83 is fixedly connected to the side brackets 82.

[0063] Furthermore, the connecting plate 83 is provided with several hollow holes.

[0064] In this embodiment, the first traveling wheel 6 is equipped with a drive motor. The rotation of the drive motor drives the first traveling wheel 6 to move. The second traveling wheel 10 moves synchronously with the first traveling wheel 6 and plays a supporting role. The first traveling wheel 6 has a large wheel diameter, thus possessing a certain obstacle-crossing ability. When encountering some obstacles, it can cross the obstacles and transport the X-ray inspection device 1 to a suitable X-ray inspection position. For example, when the first traveling wheel 6 encounters the tension clamp to be inspected, it can cross the tension clamp and bring the tension clamp into the vertical area of ​​the supporting frame 3, thereby enabling the X-ray inspection device 1 to perform effective X-ray inspection on the tension clamp at that position.

[0065] In this embodiment, both the first walking wheel 6 and the second walking wheel 10 use brushless DC motors in conjunction with planetary reducers to provide driving force, thereby ensuring the stability of the power of each wheel and the reliability of the walking process while ensuring the mobility of this embodiment.

[0066] Based on this, the connecting plate 83 and the side bracket 82 ensure the normal rotation of the first traveling wheel 6 and the second traveling wheel 10, and the hollow hole of the connecting plate 83 prevents the aerodynamics during the walking process from affecting the first traveling wheel 6 and the second traveling wheel 10.

[0067] Furthermore, a locking component 9 is provided on the side of the second wheel bracket 8, which can abut against or disengage from the wheel surface of the second traveling wheel 10.

[0068] Furthermore, the locking assembly 9 includes a telescopic rod 91, one end of which is fixed to the second wheel bracket 8, and the other end of which is provided with a hinged end 92. A limit frame 93 is fixed to the side of the second wheel bracket 8, and the limit frame 93 is hinged to the side of the hinged end 92. The telescopic rod 91 is hinged to the end of the hinged end 92.

[0069] An arc-shaped rod 94 is fixed to the other end of the hinged end 92 away from the telescopic rod 91, and the arc-shaped rod 94 bends and extends toward the second traveling wheel 10.

[0070] Furthermore, a friction roller 95 is fixed to the end of the arc-shaped rod 94.

[0071] When braking is required in this embodiment, the telescopic rod 91 extends, and the hinged end 92 rotates around the limiting frame 93 under the push of the telescopic rod 91, squeezing and pushing the arc-shaped rod 94 to swing towards the wheel surface of the second traveling wheel 10. The arc-shaped rod 94 pushes the friction roller 95 to press the power transmission wire in contact with the wheel surface of the second traveling wheel 10 to achieve frictional braking. The telescopic rod 91 is a pneumatic or hydraulic rod, which pushes the hinged end 92 using pneumatic or hydraulic pressure. Since the end of the hinged end 92 is hinged to the end of the telescopic rod 91, and the side of the hinged end 92 is hinged to the limiting frame 93, the position of the hinged end 92 remains unchanged and rotates around the hinge point between the limiting frame 93 and the hinged end 92. This rotation can push the arc-shaped rod 94 to swing and drive the friction roller 95 to press the power transmission wire in contact with the wheel surface of the second traveling wheel 10, thereby achieving frictional braking. During braking, the stability of the overall braking process can be increased by increasing static friction, and hard contact can be avoided to prevent damage to the cable surface.

[0072] When braking is not required in this embodiment, the friction roller 95 can be used to assist in maintaining stability. For example, when walking on a slope or when it is necessary to step over a tension clamp, the second traveling wheel 10 presses the cable on it, and the friction roller 95 is used to abut the cable below the second traveling wheel 10, thereby achieving bidirectional clamping of the cable. By increasing static friction to resist the effect of gravity, this embodiment is prevented from sliding down the slope, thereby effectively improving the actual climbing ability of this embodiment.

[0073] The improved climbing ability is mainly reflected in the fact that the cable is simultaneously compressed by two components in two different directions, namely the wheel surface of the second traveling wheel 10 and the surface of the friction roller 95. By relying on the rolling friction in two directions, the cable is continuously clamped during the walking process. This allows for the use of more contact area to increase friction when climbing, making it less likely for the cable to slip on slopes.

[0074] Based on this, the driving force of each wheel is activated, which can effectively complete the operation of climbing uphill. There is no need to accelerate uphill; only torque needs to be applied to climb uphill and cross the clamp. Slow climbing can also be achieved. The friction roller 95 is also rolling at this time and will not become a resistance force.

[0075] Furthermore, the second wheel bracket 8 is provided with a connecting bar 84 on the side near the X-ray detection device 1. One end of the connecting bar 84 is fixed to the second wheel bracket 8, and the other end is fixed to the X-ray detection device 1.

[0076] Since a large force is required to stop the second traveling wheel 10, the locking component 9 will exert lateral pressure on the second wheel support 8. In order to avoid deformation of the second wheel support 8 due to shear stress, this embodiment connects the second wheel support 8 and the X-ray detection device 1 through the connecting rod 84, so as to effectively utilize the stability of the X-ray detection device 1 to maintain the stability of the second wheel support 8.

[0077] In this embodiment, the first traveling wheel 6 is an obstacle-crossing wheel, and the second traveling wheel 10 is a load-bearing wheel. Both are driven by a brushless DC motor and a planetary reducer, so that each wheel can provide power and there will be no power loss during obstacle crossing, thereby improving the overall mobility of this embodiment. By driving the rotation of the motor, this embodiment moves on the power transmission line, thereby changing the position of this embodiment on the power transmission line, so as to achieve the purpose of X-ray inspection of tension clamps at different positions.

[0078] In this embodiment, both the first limiting track 4 and the second limiting track 7 are provided with several detachable positioning holes, thereby facilitating the detachable and fixed position adjustment of the first wheel bracket 5 and the second wheel bracket 8 in this embodiment to adapt to the spacing of the power transmission line to be tested. The detachable fixing method in this embodiment is bolt fixing.

[0079] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
