Description

Technical Field

[0001] The present invention relates to the field of insulator deflection test devices, and in particular to a deflection detection test machine for hollow or solid insulators used in power stations under bending force. Background Art

[0002] Insulators play a key role in the field of power transmission, and their mechanical properties, especially deflection index, have a decisive impact on the safe and stable operation of the power system. At present, in the deflection test of insulators, although there are existing deflection test devices available, there are many significant problems.

[0003] The deflection test equipment in the prior art is mostly focused on the elastic insulators used on the line, and it mainly conducts deflection tests on the axial direction of the insulators. However, there is a lack of specialized testing equipment for fixed insulators used in power stations. In the actual operating environment, the accurate testing of the lateral deflection of power station insulators is extremely critical, but the current technology has obvious gaps in this regard and cannot meet the comprehensive testing needs of power station insulators.

[0009] In a preferred embodiment, the second connecting body further includes a central body, and the ends of the telescopic rods are connected to the central body.

[0010] In a preferred embodiment, the second connecting body further comprises a probe rod, an end of which is connected to the central body.

[0011] In a preferred embodiment, the support is configured as an umbrella, and the traction rope is connected to the top of the umbrella.

[0013] In a preferred embodiment, the traction member further includes a winding wheel and a traction motor, the traction wire is wound around the winding wheel, and the traction motor is used to drive the winding wheel to rotate.

[0014] In a preferred embodiment, the traction component also includes a shell, a first gear, a second gear and a power supply, the winding wheel, the traction motor, the first gear, the second gear and the power supply are arranged in the shell, the first gear and the second gear cooperate with each other, the wheel diameter of the first gear is larger than the wheel diameter of the second gear, the winding wheel is coaxially arranged with the first gear, the traction motor is connected to the second gear, and the power supply is electrically connected to the traction motor.

[0015] In a preferred embodiment, an adsorption magnet is provided on the housing.

[0016] In a preferred embodiment, a displacement detector is further included, and the displacement detector is disposed on the base.

[0017] Compared with the prior art, the present invention provides a deflection detection test machine for hollow or solid insulators for power stations under bending force. When conducting the test, the insulator is installed on a support seat, the support seat is provided with a support flange, the insulator also has a flange, and the two flanges are provided with through holes for fixing. At this time, convenient traction of the insulator is achieved through a traction member. The specific operation is: the first connector is located in the through hole of the support seat flange, and the second connector is located in the through hole of the insulator flange. By pulling the traction rope, the first connector and the second connector can be brought close to each other, thereby pulling the insulator. In this process, the tapered portion on the first connector plays a good guiding role. Through two such traction members, the alignment of the through holes can be achieved, which solves the problem of time-consuming and labor-intensive insulator angle adjustment in the prior art.

Next, the insulator is fixed on the support seat, and then the lifting drive motor is started again to drive the lifting seat down until the connection seat contacts and connects with the upper end of the insulator, thereby realizing the placement and fixation of the insulator in the test device.

[0019] Then, start the servo motor to drive the oil cylinder. When the oil cylinder moves, it will drive the connecting seat to produce corresponding movements. Due to the precise control of the servo motor, the operation of the oil cylinder is smoother and more precise. Under the action of the oil cylinder, a bending force perpendicular to the axis of the insulator is applied to the top of the insulator, causing the insulator to swing back and forth. During the reciprocating swing of the insulator, the corresponding measuring device is used to measure the left and right swing displacement in real time. The obtained measurement data is the deflection test data of the insulator.

[0020] In the present invention, through the design of the traction member, during the installation and fixing process of the insulator, the through hole on the insulator flange can be quickly aligned with the through hole on the support base flange. Compared with the traditional method, there is no need to perform a time-consuming and laborious angle adjustment process, which greatly saves installation time and improves the overall experimental efficiency. The tapered portion on the first connector plays a good guiding role in the alignment process, further ensuring the rapid alignment of the through hole, making the installation operation more convenient and efficient.

[0021] By setting up a precise lifting drive motor and lifting frame structure, the stable lifting of the cantilever can be ensured, thereby ensuring a firm and reliable connection between the connecting seat and the insulator. Through the cooperation of components such as the servo motor and the cylinder, when conducting a deflection test, force can be accurately applied to the insulator, thereby improving the accuracy of the experimental results.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0032] like Figures 1 to 6 As shown, a deflection detection test machine for hollow or solid insulators under bending force for power stations includes a base 1, a lifting drive motor 2, a lifting frame 3, a lifting seat 4, a cantilever 5, a connecting seat 6, a supporting seat 7, a cylinder 35, a servo motor (not shown in the figure) and a traction member 9. The lifting frame 3 and the supporting seat 7 are arranged on the base 1, a driving connection member is arranged in the lifting frame 3, the lifting drive motor 2 is arranged on the top of the lifting frame 3, the driving connection member connects the lifting drive motor 2 and the lifting seat 4, and the lifting seat 4 It is arranged on the lifting frame 3 and can move up and down along the lifting frame 3. The oil cylinder 35 is arranged on the lifting seat 4. The servo motor is used to drive the oil cylinder 35. One end of the cantilever 5 is connected to the lifting seat 4, and the other end is connected to the connecting seat 6. The traction member 9 includes a first connector 16, a traction rope 31 and a second connector 19. One end of the traction rope 31 is connected to the second connector 19, and the other end passes through the first connector 16. The first connector 16 has a tapered portion 18. The traction member 9 has at least two.

[0033] In the deflection detection test machine for hollow or solid insulators for power stations under bending force of this embodiment, when conducting the test, the insulator 34 is installed on the support seat 74, the support seat 74 is provided with a support flange, the insulator 34 is also provided with a flange, and the two flanges are provided with through holes for fixing. At this time, the insulator 34 is conveniently pulled by the traction member 9. The specific operation is: the first connector 16 is located in the through hole of the flange of the support seat 7, and the second connector 19 is located in the through hole of the flange of the insulator 34. By pulling the traction rope 31, the first connector 16 and the second connector 19 can be brought close to each other, so as to pull the insulator 34. In this process, the tapered portion on the first connector 16 plays a good guiding role. Through two such traction members 9, the alignment of each through hole can be achieved, which solves the problem of time-consuming and labor-intensive angle adjustment of the insulator 34 in the prior art.

[0034] After the insulator 34 is installed on the support seat 7, the lifting drive motor 2 is started, and its power is transmitted through the driving connection component, so that the lifting seat 4 moves up and down on the lifting frame 3, and the oil cylinder 35 installed on the lifting seat 4 moves up and down synchronously, and the cantilever 5 and the connecting seat 6 connected to the oil cylinder 35 also move up and down together. Next, the insulator 34 is fixed on the support seat 7, and then the lifting drive motor 2 is started again to drive the lifting seat 4 to descend until the connecting seat 6 contacts and connects with the upper end of the insulator 34, thereby realizing the placement and fixation of the insulator 34 in the test device.

[0035] Then, the servo motor is started to drive the oil cylinder 35 to work. When the oil cylinder 35 moves, it will drive the connecting seat 6 to produce corresponding movements. Due to the precise control of the servo motor, the operation of the oil cylinder 35 is smoother and more precise. Under the action of the oil cylinder 35, a bending force perpendicular to the axis of the insulator 34 is applied to the top of the insulator 34, causing the insulator 34 to swing back and forth. During the reciprocating swing of the insulator 34, the left and right swing displacement is measured in real time using a corresponding measuring device, and the obtained measurement data is the deflection test data of the insulator 34.

[0036] In the present invention, through the design of the traction member 9, during the installation and fixing process of the insulator 34, the through hole on the flange of the insulator 34 can be quickly aligned with the through hole on the flange of the support seat 7. Compared with the traditional method, there is no need to perform a time-consuming and laborious angle adjustment process, which greatly saves installation time and improves the overall experimental efficiency. The tapered portion on the first connector 16 plays a good guiding role in the alignment process, further ensuring the rapid alignment of the through hole, making the installation operation more convenient and efficient.

[0037] By setting up a precise lifting drive motor 2 and a lifting frame 3 structure, the stable lifting of the cantilever 5 can be ensured, thereby ensuring that the connection between the connecting seat 6 and the insulator 34 is firm and reliable. Through the cooperation of components such as the servo motor and the cylinder 35, when conducting a deflection test, a force can be accurately applied to the insulator 34, thereby improving the accuracy of the experimental results.

[0038] The drive connection member may be configured as a traction wire rope.

[0039] In order to achieve convenient connection of the second connecting body 19, the second connecting body 19 includes a bracket 20 and a plurality of telescopic rods 22. The bracket 20 is provided with a plurality of guide channels 21 corresponding to the plurality of telescopic rods 22. The plurality of guide channels 21 are evenly distributed around the circumference. The telescopic rod 22 includes a first rod body 23, a second rod body 25 and a telescopic spring 28. An insertion hole 24 is provided at the end of the first rod body 23. The telescopic spring 28 is provided in the insertion hole 24. One end of the second rod body 25 is inserted into the insertion hole 24 and abuts against the telescopic spring 28. A first arcuate surface 26 and a second arcuate surface 27 are provided on the edge of the end surface of the other end. The first arcuate surface 26 and the second arcuate surface 27 are arranged opposite to each other. The telescopic rod 22 passes through the guide channel 21.

[0040] When connecting with the flange through hole on the insulator 34, the second connector 19 is pushed into the through hole from bottom to top. During the process, the second rod body 25 compresses the telescopic spring 28 to shrink the telescopic rod 22 so that it can pass through the through hole smoothly. The telescopic rod 22 is pushed to extend by the rear spring to prevent the second connector 19 from passing through the through hole again, thereby achieving connection with the flange. After the traction is completed, a large traction force is applied to the traction rope 31 to shrink the telescopic rod 22 and withdraw it from the through hole to complete the traction operation. During the connection and disconnection process, the first arc surface 26 and the second arc surface 27 on the edge of the end face of the second rod body 25 play a guiding role to prevent jamming.

[0041] The connection is convenient and efficient. The telescopic rod 22 is retractable, which makes the connection operation simple. It can be automatically connected by just pushing it in, which greatly improves the convenience and efficiency of operation. Secondly, the connection is stable and reliable. After the connection, the telescopic rod 22 is extended under the action of the spring to prevent accidental separation, ensuring stable and reliable traction operation. Moreover, it is easy to separate. After the traction is completed, the traction force applied can make the telescopic rod 22 shrink and smoothly exit the through hole, saving operation time. In addition, the guiding effect is good. The first arc surface 26 and the second arc surface 27 avoid jamming during the connection and separation process, making the operation smooth.

[0042] In order to ensure the stability of the structure, the second connecting body 19 further includes a central body 29 , and the ends of the telescopic rods 22 are connected to the central body 29 .

[0043] In order to facilitate the second connector 19 to pass through the flange hole of the insulator 34 smoothly, the second connector 19 also includes a probe rod 30, the end of which is connected to the center body 29. When passing through, the probe rod 30 passes through first, and then the probe rod 30 can be grasped by hand to pull the second connector 19 as a whole through the flange hole of the insulator 34.

[0044] In order to ensure a stable state during traction, the support 20 is configured to be an umbrella shape, and the traction rope 31 is connected to the top of the umbrella shape.

[0045] In order to facilitate fixing the first connecting body 16 in the flange through hole of the supporting seat 7 , the first connecting body 16 further includes a cylindrical portion 17 , and the conical portion 18 is connected to the cylindrical portion 17 .

[0046] In order to achieve stable cooperation between the columnar portion 17 and the flange through hole of the support seat 7, an elastic cushion layer can be provided on the periphery of the columnar portion 17 so that it can be squeezed and inserted into the flange through hole of the support seat 7 to achieve fixation. In this embodiment, the following fixing methods are also provided: The traction member 9 further comprises a winding wheel 32 and a traction motor 33. The traction wire is wound around the winding wheel 32. The traction motor 33 is used to drive the winding wheel 32 to rotate. When traction is performed, the traction motor 33 drives the winding wheel 32 to rotate, thereby achieving traction work.

[0047] Further, the traction member 9 further includes a housing 10, a first gear 11, a second gear 12 and a power source 13. The winding wheel 32, the traction motor 33, the first gear 11, the second gear 12 and the power source 13 are arranged in the housing 10. The power source 13 can be set as a rechargeable battery. The first gear 11 and the second gear 12 cooperate with each other. The wheel diameter of the first gear 11 is larger than the wheel diameter of the second gear 12, so as to achieve a larger torque setting. The winding wheel 32 is coaxially arranged with the first gear 11. The traction motor 33 is connected to the second gear 12. The power source 13 and the traction motor 33 are electrically connected. The columnar portion 17 is fixedly connected to the housing 10. When working, the traction motor 33 drives the second gear 12 to rotate, thereby driving the first gear 11 to rotate, and then driving the winding wheel 32 to rotate, so as to achieve traction work.

[0048] In order to achieve convenient placement, the shell 10 is provided with an adsorption magnet 14, and the shell 10 can be conveniently adsorbed on the flange of the support seat 7 through the adsorption magnet 14.

[0049] The deflection detection test machine for hollow or solid insulators for power stations under bending force of this embodiment also includes a displacement detector 8, which is placed on the base 1. The displacement detector 8 can be specifically set as an infrared displacement detector 8. When working, it detects the displacement of the second umbrella of the insulator 34 from the bottom to the upper direction, thereby realizing displacement detection during the deflection test.
