The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

For the convenience of realizing the rotation of the clamping assembly 3, preferably, connecting rods 8 corresponding to the clamping assemblies 3 are provided on the rotating column 4, and both ends of each connecting rod 8 are respectively hinged to its corresponding clamping assembly 3 and the rotating column 4 to synchronously drive each clamping assembly 3 to rotate. When a plurality of heavy insulators to be tested are installed on the mounting bracket 3, it may cause the rotating column 4 to move downward under the action of gravity, which may cause the rotating column 4 to press against the base 1. Among them, a driving mechanism (not shown in the figure) may be connected to the rotating column 4 to drive the rotating column 4 to rotate, and then drive each clamping assembly 3 and the insulator to be tested clamped by the clamping assembly 3 to rotate through the connecting rod 8.

[0029] To buffer the force between the buffer rotating column 4 and the base 1, preferably, the buffer assembly 5 is arranged at the bottom end of the rotating column 4 to buffer the rotating column 4 when the mounting frame 3 mounts a plurality of heavy insulators to be measured, so as to perform buffer shock protection to prevent the multi-station support seat from being damaged.

[0030] To ensure the accuracy of the detection of the insulator to be measured, the cleaning assembly 6 can be arranged on the mounting frame 2 to clean the surface of the insulator to be measured that slides along the mounting frame 2 with the clamping assembly 3, so as to avoid errors in the detection data caused by surface dust.

Moreover, the first clamping plates 33 and the rotation axis 32 are rotationally connected through transmission members 34 to drive the first clamping plates 33 to move radially towards the rotation axis 32 along the clamping box 31 so as to clamp the insulator under test from the outer edge thereof. Specifically, there may be three first clamping plates 33 which are evenly distributed circumferentially along the rotation axis 32; the transmission member 36 is used to convert the rotation of the rotation axis 32 into a linear motion of the first clamping plates 33 so that the first clamping plates 33 are clamped on the outer edge of the insulator under test, enabling the insulator under test to be accurately positioned at the middle position of the clamping box 31, such as the central position, which provides convenience for subsequent detection work. To facilitate clamping of insulators under test with different umbrella disk diameters, preferably, a second clamping plate 34 is further provided between the first clamping plates 33 and the rotation axis 32 to clamp the insulator under test through the second clamping plate 34 or the first clamping plates 33.

So when the first clamping plates 33 move towards the axis of the clamping box 31 under the action of the transmission member 36, they compress the first spring 37 to make the second clamping plate 34 move towards the axis of the clamping box 31 and compress the second spring 38 at the same time. In addition, the arrangement of the first spring 37 and the second spring 38 can also achieve the reset of the second clamping plate 34 and the first clamping plates 33. To reduce the friction of the sliding of the clamping assembly 3, preferably, balls 39 may be provided at the bottom of the clamping box 31 to reduce the frictional resistance between the clamping assembly 3 and the annular guide rail 21.

[0036] Continue to refer to Figure 3, the transmission member 36 includes: a wire take-up reel 361 and a connecting rope 362 wound around the wire take-up reel 361. Specifically, the wire take-up reel 361 can be fixedly connected to the rotating shaft 32 to rotate with the rotating shaft 32; there can be multiple connecting ropes 362, which are arranged in one-to-one correspondence with the first clamping plate 33; one end of each connecting rope 362 is wound around the wire take-up reel 361 and passes through the second clamping plate 34, and the other end is fixedly connected to the first clamping plate 33, so that when the wire take-up reel 361 rotates with the rotating shaft 32, the connecting rope 362 can be wound and unwound, and further, when the connecting rope 362 is wound, that is, wound around the wire take-up reel 361, the first clamping plate 33 moves towards the axis of the clamping box 31, and when the connecting rope 362 is unwound, that is, released from the wire take-up reel 362, it is reset under the action of the first spring 37 and the second spring 38. Among them, a clamping strip can be provided on the rotating shaft 32 to clamp the wire take-up reel 361, so that the wire take-up reel 361 rotates synchronously with the rotating shaft 32, and further realizes the winding and unwinding of the connecting rope 362.

[0037] Continue to refer to Figures 1 to 4 , the buffer assembly 5 includes: a buffer column 51, an air chamber 52 and an airbag 53; wherein, the end of the buffer column 51 is slidably arranged in the air chamber 52, the airbag 53 is communicated with the air chamber 52, and a sliding plate 54 is provided on the side of the airbag 53 away from the air chamber 52, and it is slidably connected to the base 1; a buffer groove is provided on the base 1, and it is arranged at an angle with the sliding direction of the sliding plate 54; two sliders 55 are arranged in the buffer groove, and they are arranged side by side and slidably connected in the buffer groove along the length direction of the buffer groove (such as Figure 4 shown in the vertical direction), and each slider 55 is connected to the end of the buffer groove (such as Figure 4A buffer spring 56 may be provided between the upper and lower ends shown; two hinge rods 57 corresponding to the sliders 55 one by one are connected to the side wall of the slide plate 54 away from the airbag 53. One end of each hinge rod is hinged to the slide plate 54, and the other end is hinged to the corresponding slider 55. Specifically, the bottom end of the buffer column 51 is slidably disposed in the air chamber 52, and the buffer column 51 is used to support the rotating column 4; two airbags 53 may be symmetrically disposed on both sides of the air chamber 52, and they may be symmetrically bonded in the base 1 and are both communicated with the air chamber 52; a slide plate 54 may be provided on one side of each airbag 53 away from the air chamber 52, that is, the airbags 2, the slide plates 54, the hinge rods 57, etc. are all in multiple groups and are symmetrically disposed with respect to the air chamber 52 to improve its buffering effect. During specific implementation, since multiple insulators under test are installed on the mounting frame 2 and move downward, the buffer column 51 is pressed downward under the action of the rotating column 4. Under the action of air pressure, the airbag 53 expands and abuts against the slide plate 54, causing the slide plate 54 to move in a direction away from the buffer column 51. The hinge rod 57 pushes the slider 55 to compress the buffer spring 56 under the action of the slide plate 54, so as to buffer the pressure through the gas in the air chamber 52 and the airbag 53 and the buffer spring 56, and avoid damage to the entire device. Among them, the movement paths of the slide plate 54 and the airbag 53 interfere with each other, so that the airbag 53 can push the slide plate 54 to slide when it expands.

[0038] Continue to refer to Figure 2 and Figure 5 As shown in FIGS. and, the cleaning assembly 6 includes: a support plate 61, a brush 62, a first electromagnet 63 and a second electromagnet 64; wherein, a sliding groove 611 is provided on the support plate 61, the first electromagnet 63 is disposed at the end of the sliding groove 611, the second electromagnet 64 is slidably disposed in the sliding groove 611, and the second electromagnet 64 and the first electromagnet 63 are spaced apart; the brush 62 is rotatably connected to the second electromagnet 64, and the brush head of the brush 62 faces the first electromagnet 63, so that when the first electromagnet 63 and the second electromagnet 64 are energized, the second electromagnet 64 moves towards the first electromagnet 63 to drive the brush 62 to move towards the mounting frame 2, so that the brush head moves to one side of the insulator under test to clean the surface of the insulator under test. Specifically, the support plate 61 may be an integral structure with the mounting frame 2; the first electromagnet 6 may be a fixed electromagnet, which is fixedly connected to the end of the sliding groove 611 (such as Figure 5at the lower right end as shown); the second electromagnet 64 can be a moving electromagnet, which is arranged at an interval from the second electromagnet 64 so that when the two are energized, they attract each other and the second electromagnet 64 moves towards the first electromagnet 63. Preferably, an electromagnet reset member 65 is provided between the second electromagnet 64 and the support plate 61 to drive the second electromagnet 64 to reset when the first electromagnet 63 and the second electromagnet 64 are de-energized; wherein, the electromagnet reset member 65 can be a spring, and its two ends are respectively connected to the upper left end of the sliding groove 611 and the second electromagnet 64 to realize the reset of the second electromagnet 64, thereby terminating the cleaning of the insulator under test by the brush 62, and at the same time avoiding the interference of the brush 62 with the rotation of the insulator under test.

[0039] In this embodiment, for the convenience of controlling the movement of the second electromagnet 64, preferably, a time relay (not shown in the figure) is connected to the first electromagnet 63 and the second electromagnet 64 for timing and controlling the energization or de-energization of the first electromagnet 63 and the second electromagnet 64. Specifically, when the clamping assembly 3 rotates to a preset position, the delay-off contact of the time relay energizes the power supply to the first electromagnet 63 and the second electromagnet 64, and at the same time the time relay starts timing, and the second electromagnet 64 moves towards the first electromagnet 63 (as Figure 5 shown moving towards the lower right side) until the first electromagnet 63 and the second electromagnet 64 are attracted. At this time, the brush 62 moves to one side of the insulator under test with the second electromagnet 64 to clean the insulator under test; when the timing of the time relay ends, the first electromagnet 63 and the second electromagnet 64 lose power, and at the same time the electromagnet reset member 65 pulls the second electromagnet 64 to make the second electromagnet 64 reset, and the brush 62 moves with the second electromagnet 64 to terminate the cleaning. Among them, the timing time of the time relay can be determined according to the actual situation, and no limitation is made to it in this embodiment.

[0040] In this embodiment, further preferably, a position detector 66 is further provided on the mounting bracket 2 to detect the position of the clamping assembly 3 and send an energization signal to the time relay when the clamping assembly 3 rotates to a preset position; the time relay is used to receive the energization signal and start timing while controlling the energization of the first electromagnet 63 and the second electromagnet 64. Specifically, when the clamping assembly 3 rotates to a preset position, the position detector sends an energization signal to the time relay, and the delay-off contact of the time relay energizes the power supply to the first electromagnet 63 and the second electromagnet 64, and at the same time the time relay starts timing, and the first electromagnet 63 moves towards the second electromagnet 64 (as Figure 5It moves downward to the right as shown until the first electromagnet 63 and the second electromagnet 64 are attracted to each other. At this time, the brush 62 moves to one side of the insulator to be measured along with the first electromagnet 63 to clean the insulator to be measured. When the timing of the time relay ends, the first electromagnet 63 and the second electromagnet 64 lose power. At the same time, the electromagnet reset member 65 pulls the first electromagnet 63 to reset the first electromagnet 63, and the brush 62 moves along with the first electromagnet 63 to terminate the cleaning. Among them, the position detector 66 can be arranged on the annular guide rail 21 to detect the position of the clamping assembly 3, especially to detect whether the clamping assembly 3 rotates to the preset position, that is, the groove 211 of the annular guide rail 21.

Among them, a groove 211 is provided on the annular guide rail 21. The contact block 661 protrudes partially outside the groove 211 and is rotatably connected to the groove 211 to contact the clamping assembly 3. The first contact 662 is arranged on the surface of the contact block 661 opposite to the groove wall of the groove 211, and the second contact 663 is arranged on the groove wall of the groove 211 to detect the position of the clamping assembly 3 when the clamping assembly 3 contacts the contact block 661 and causes the contact block 661 to rotate into the groove 211, so that the second contact 663 contacts the first contact 662. A contact reset member 664 is provided between the contact block 661 and the groove 211 to push the contact block 661 to rotate to protrude partially outside the groove 211. Specifically, the groove 211 can be arranged at the preset position. One end of the contact block 661 (such as Figure 6 the right lower end shown) is rotatably connected to the groove 211, and the other end (such as Figure 6The left end shown in the figure is a free end, so that in the free state, the abutment block 661 is partially protruded outside the groove 211 to abut the clamping component 3, that is, when the clamping component 3 slides along the annular guide rail 21 to the groove 211, the abutment block 661 abuts against the clamping component 3, and under the pressure of the clamping component 3, the abutment block 661 rotates until it is completely set in the groove 211. At this time, the first contact 662 and the second contact 663 are in contact, and a power-on signal can be sent to the time relay, that is, it is detected that the clamping component 3 rotates to the groove 211; when the first contact 662 and the second contact 663 are in contact, the rotation of the clamping component 3 can be stopped synchronously, so that the brush can pass through. 62 cleans the insulator to be tested clamped on the clamping assembly 3 at the groove 211; when the timing of the time relay ends, the first electromagnet 63 and the second electromagnet 64 lose power, the electromagnet reset member 65 pulls the first electromagnet 63 to reset the first electromagnet 63, and the brush 62 moves with the first electromagnet 63 to terminate the cleaning. At the same time, the clamping assembly 3 can start to rotate so as to move away from the interference block 661, so that the interference block 661 is reset to the part protruding outside the groove 211 under the action of the interference reset member 664, so that when the clamping assembly 3 or the clamping assembly 3 of other workstations rotates to the groove 211, the interference block 661 and the clamping assembly 3 are in conflict again.

Among them, the top plate of the base 1 (relative to Figure 1 As for the position shown in the figure, a mounting groove 11 may be provided, which may penetrate the top plate along the thickness direction of the top plate, or may be a blind hole with an opening at the top. A fan 72 may be provided in the mounting groove 11 to blow air from the top opening for dust removal; the air outlet groove 721 may be a spiral structure, of course, it may also be other structures, and no limitation is made in this embodiment.

[0043] The working process of the multi-station support seat is as follows: first, the test insulator is placed in the clamping box 31; when a plurality of heavy insulators are mounted on the mounting frame 3, the buffer column 51 is pressed down, so that the air bag 53 is expanded under the action of air pressure, thereby causing a conflict with the slide plate 54, so that the pressure is buffered under the action of the hinge rod 57, the slider 55 and the buffer spring 56 to prevent the entire device from being damaged;

[0044] Then, the rotating shaft 32 is rotated to drive the take-up drum 361 to rotate, so that the first clamping plate 33 and the second clamping plate 34 are driven to slide under the action of the connecting rope 362, so that the insulators to be tested of various specifications can be clamped and fixed by the first clamping plate 33 or the second clamping plate 34, and the insulators can be accurately positioned at the center of the clamping box 31, which provides convenience for the later detection work;

[0045] Finally, by blowing air with the blower 75, the air duct 72 is driven to rotate, so as to drive the rotating column 4 to rotate, and the clamping assembly 3 and the working position of the insulator to be measured are converted; and the air flow in the air duct 72 flows out from the air outlet groove 721 into the sealing cavity 71, and under the action of the nozzle 76, the air flow collides with the rotating blade 731, thereby driving the driving column 73 to rotate, so that the fan 74 rotates to perform dust removal work; at the same time, when the rotating column 4 rotates, under the action of the connecting rod 8, the clamping box 31 can be driven to rotate, realizing the conversion between multiple detection stations. And because the mounting frame 3 is in a folded ring shape, the clamping box 31 on one side of the mounting frame 3 is kept horizontal, and the clamping box 31 on the other side of the mounting frame 3 has an angle with the horizontal plane, which facilitates the installation by the staff; when the clamping box 31 rotates along the guide rail 21, when the clamping box 31 abuts against the abutting block 661, the first contact 662 and the second contact 663 are in contact, sending a power-on signal to the time relay, and the time relay controls the first electromagnet 63 and the second electromagnet 64 to be powered on and starts timing at the same time; when the first electromagnet 63 and the second electromagnet 64 are powered on, they attract each other, so that the second electromagnet 64 drives the brush 62 to slide, thereby cleaning the insulator passing through the brush 62 to avoid errors in the detection work caused by dust on the surface of the insulator to be measured.

[0046] In summary, the multi-station support seat for insulator detection provided in this embodiment realizes the clamping of the insulator to be measured through a plurality of rotatable clamping assemblies on the mounting frame 2, provides a plurality of stations and the conversion between multiple stations, so as to perform simultaneous operations of multiple tasks such as installation and detection, and solves the problem of time-consuming and laborious caused by the frequent manual movement of samples or the movement of positions by the detection personnel when detecting insulators; the rotating column 4 is buffered by the buffer assembly 5 for buffer shock protection, so that the multi-station support seat is not damaged; the surface of the insulator to be measured is cleaned by the cleaning assembly 6 to avoid errors in the detection data caused by surface dust; the dust removal work is carried out by the dust removal assembly 7 to avoid the accumulation of dust on the base 1.
