DETAILED DESCRIPTION

[0043] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments in which the present invention can be implemented.

[0044] The present invention provides a lightning arrester DC parameter testing device, the structure of which is as follows Figure 1 and Figure 2 As shown, it includes a vertical transfer frame 1 and a loading frame 2, a detection mechanism 3, a first unloading mechanism 4 and a second unloading mechanism 5 arranged in sequence along the rotation direction of the vertical transfer frame 1; the vertical transfer frame 1 includes two turntables 11 and multiple groups of brackets 12, the two turntables 11 are arranged oppositely and fixedly connected, the multiple groups of brackets 12 are distributed on the vertical transfer frame 1 along the circumferential direction, the number of the brackets 12 in each group is two, the two brackets 12 are arranged oppositely, and are rotatably arranged on the inner side walls of the two turntables 11 respectively; the vertical transfer frame 1 also includes a motor for driving the two turntables 11 to rotate;

[0045] The first end of the loading rack 2 extends between the two rotating disks 11 to form a loading position on the upper surface of the first end of the loading rack 2; when the vertical transfer rack 1 rotates, the supporting opening of the bracket 12 is always facing upward, so that the two brackets 12 arranged opposite to each other can cooperate with the screws at both ends of the arrester 100 in the loading position to lift the arrester 100 and load it onto the vertical transfer rack 1;

[0046] The detection mechanism 3 is used to detect the DC parameters of the arrester 100;

[0047] The first unloading mechanism 4 is used to unload the arrester 100 that fails the inspection;

[0048] The second unloading mechanism 5 is used to unload the lightning arrester 100 that has passed the inspection.

[0049] It is easy to understand that by extending the first end of the loading rack 2 between the two turntables 11 and setting the supporting port of the bracket 12 to always face upward, when the bracket 12 rotates to the bottom of the first end of the loading rack 2 along with the vertical transfer rack 1, the two brackets 12 can cooperate with the screws at both ends of the lightning arrester 100 in the loading position to lift the lightning arrester 100 upward to disengage from the loading rack 2 and load it onto the vertical transfer rack 1.

[0050] Specifically, since the loading rack 2, the detection mechanism 3, the first unloading mechanism 4 and the second unloading mechanism 5 are respectively arranged at four positions around the vertical transfer rack 1, in order to improve the overall compactness of the equipment, in the embodiment of the present invention, the bracket 12 is provided in four groups, and the number of the brackets 12 in each group is set to two.

[0051] like Figure 4 Shown Figure 1 The structural schematic diagram after removing the detection mechanism 3 and the fixed frame 6, in order to realize that when the vertical transfer frame 1 rotates, the supporting port of the bracket 12 is always facing upward, the bracket 12 includes a storage bracket 121 and a counterweight block 122, wherein the storage bracket 121 is rotatably arranged on the inner side wall of the corresponding turntable 11, and the top of the storage bracket 121 is provided with a V-shaped supporting port; the counterweight block 122 is fixedly connected to the bottom end of the storage bracket 121.

[0052] It should be noted that in order to achieve stable support of the lightning arrester 100 by the bracket 12, when the storage bracket 121 supports the lightning arrester 100, the supporting port of the storage bracket 121 should also face upward, so the weight of the counterweight block 122 should be at least greater than half the weight of the lightning arrester 100.

[0053] Please continue to refer to Figure 2According to one embodiment of the present invention, the loading rack 2 includes a cache rack 21 and a material baffle plate 22, wherein the first end of the cache rack 21 (the cache rack 21 has two ends, and the first end is one of the two ends) extends between the two turntables 11, and the width of the first end of the cache rack 21 is less than the total length of the lightning arrester 100, so that the screws at both ends of the lightning arrester 100 in the loading position are exposed from both sides of the first end of the cache rack 21; the material baffle plate 22 is fixedly arranged at the first end of the cache rack 21, and the material baffle plate 22 is used to prevent the lightning arrester 100 in the loading position of the cache rack 21 from falling.

[0054] Generally, the loading rack 2 should also include a material moving component that moves the lightning arrester 100 placed on the cache rack 21 to the loading position. In order to simplify the structural design of the loading rack 2, in an embodiment of the present invention, the cache rack 21 is tilted so that the height of the first end of the cache rack 21 is lower than the height of the other end.

[0055] It is not difficult to understand that since the loading position is set at the first end of the cache rack 21, by designing the cache rack 21 so that the height of the first end is lower than the height of the other end, when the lightning arrester 100 to be tested is placed on the cache rack 21, the lightning arrester 100 can roll freely to the loading position due to gravity; and when the lightning arrester 100 in the loading position is loaded onto the vertical transfer rack 1, the remaining lightning arresters 100 on the cache rack 21 can automatically roll to the loading position of the cache rack 21, thereby realizing automatic replenishment of the loading position.

[0056] Furthermore, the buffer material rack 21 is provided with a plurality of grooves 210 along its length direction, and the width of the grooves 210 matches the width of the raised portion of the umbrella skirt structure on the porcelain jacket of the arrester 100 .

[0057] It can be understood that the groove 210 can cooperate with the raised part of the umbrella skirt structure on the porcelain outer shell of the lightning arrester 100, and can limit and guide the lightning arrester 100 placed on the cache rack 21, thereby ensuring the position accuracy of the lightning arrester 100 rolled to the loading position, thereby ensuring that the storage bracket 121 can accurately grasp the lightning arrester 100 in the loading position.

[0058] Please continue to refer to Figure 1According to an embodiment of the present invention, the arrester DC parameter testing equipment also includes a fixed frame 6, and the vertical transfer frame 1 is rotatably set on the fixed frame 6; the detection mechanism 3 includes a DC parameter tester 31, two support frames 32 and two contact pieces 33, wherein the DC parameter tester 31 is detachably fixed on the fixed frame 6; the two support frames 32 are respectively fixed on the fixed frame 6, and are respectively located on both sides of the vertical transfer frame 1; the two contact pieces 33 are respectively fixed on the two support frames 32, and the two contact pieces 33 are respectively electrically connected to the high voltage end and the low voltage end of the DC parameter tester 31; when the screws at both ends of the arrester 100 are respectively in electrical contact with the two contact pieces 33 at the same time, the DC parameter tester 31 can detect the arrester 100.

[0059] like Figure 3 Shown Figure 2 In the enlarged schematic diagram of part A in the middle, preferably, the distance between the two contact pieces 33 gradually increases along the rotation direction of the vertical transfer rack 1, so that the two contact pieces 33 are distributed in an eight-shaped shape.

[0060] It is not difficult to understand that the two contacts 33 distributed in an eight-shaped shape can cooperate with the screws at both ends of the lightning arrester 100 to adjust the position of the lightning arrester 100 on the bracket 12 to ensure that the screws at both ends of the lightning arrester 100 can effectively contact the two contacts 33.

[0061] Please continue to refer to Figure 4 According to one embodiment of the present invention, the first unloading mechanism 4 includes a placement rack 41, a plurality of levers 42 and a driving assembly 43, wherein the placement rack 41 is fixedly arranged on the outer side of the vertical transfer rack 1; the plurality of levers 42 are distributed along an axial interval parallel to the vertical transfer rack 1; the driving assembly 43 is used to simultaneously drive the plurality of levers 42 to switch between a first position and a second position, when the lever 42 is in the first position, the lever 42 is located on the outer side of the vertical transfer rack 1; when the lever 42 is in the second position, the lever 42 intersects with the moving path of the arrester 100 on the vertical transfer rack 1, and the arrester 100 can roll along the lever 42 to the placement rack 41.

[0062] There are at least two levers 42, and the two levers 42 can be arranged corresponding to the recessed parts of the umbrella skirt structure on the porcelain jacket of the arrester 100, or can be arranged corresponding to the screws at both ends of the arrester.

[0063] Specifically, the driving assembly 43 includes a rotating shaft 431, a telescopic driving member 432, a crank 433 and a connecting rod 434, wherein the rotating shaft 431 is rotatably arranged at the bottom of the placement frame 41, and the bottom ends of the multiple levers 42 are movable through the placement frame 41 and fixedly connected to the rotating shaft 431; the telescopic driving member 432 is fixedly arranged at the bottom of the placement frame 41; the crank 433 is fixedly connected to the rotating shaft 431, one end of the connecting rod 434 is hinged to the crank 433, and the other end is hinged to the piston rod of the telescopic driving member 432; as a specific embodiment, the telescopic driving member 432 can be a cylinder or a hydraulic cylinder; in order to avoid the interference of the lever 42 with the placement frame 41 when switching between the first position and the second position, the placement frame 41 is provided with a plurality of make way grooves (not shown in the figure) corresponding to the lever 42 one by one.

[0064] Through the above design, when the piston rod of the telescopic driving member 432 is extended, the plurality of the levers 42 are in the first position, and when the piston rod of the telescopic driving member 432 is retracted, the plurality of the levers 42 are in the second position, thereby realizing the switching of the levers 42 between the first position and the second position. It should be noted that setting the driving assembly 43 to the above structural form (similar to the crank slider assembly) is only a preferred embodiment of the present invention, and does not limit the driving assembly 43. In other embodiments, the driving assembly 43 can also be set to other structural forms, such as directly driving the rotating shaft 431 to rotate forward and reverse by a forward and reverse motor, which can also realize the switching of the lever 42 between the first position and the second position.

[0065] According to one embodiment of the present invention, the second unloading mechanism 5 includes an unloading conveyor line 51 and a plurality of material blocking rods 52, wherein the unloading conveyor line 51 is arranged on the outer side of the vertical transfer frame 1, and the unloading conveyor line 51 extends to the next process of the lightning arrester production workshop. Specifically, the unloading conveyor line 51 can be a belt conveyor line; the material blocking rod 52 intersects with the moving path of the lightning arrester 100 on the vertical transfer frame 1, and the lightning arrester 100 can roll along the material blocking rod 52 onto the unloading conveyor line 51.

[0066] It can be understood that since the first unloading mechanism 4 has completed the unloading of the lightning arresters 100 that failed the inspection, the lightning arresters 100 on the vertical transfer rack 1 after unloading by the first unloading mechanism 4 are all lightning arresters with good electrical performance. When the vertical transfer rack 1 drives the lightning arrester 100 to move to the blocking rod 52, the lightning arrester 100 can roll along the blocking rod 52 to the unloading conveyor line 51, thereby completing the unloading of the lightning arrester 100.

[0067] In order to facilitate the understanding of this scheme, the following Figure 1-Figure 4 The working principle of the present invention is described in detail:

[0068] Step 1, start the motor of the vertical transfer rack 1, and place the lightning arrester 100 to be tested on the cache rack 21 in turn. Since the cache rack 21 is tilted, the lightning arrester 100 can be rolled to the loading position at the first end of the cache rack 21, and since the width of the first end of the cache rack 21 is smaller than the total length of the lightning arrester 100, the screws at both ends of the lightning arrester 100 in the loading position can be exposed from both sides of the loading position.

[0069] Step 2: When one of the brackets 12 on the vertical transfer rack 1 rotates to the bottom of the first end of the buffer rack 21, the screws at both ends of the arrester 100 in the loading position can fall into the V-shaped loading opening of the storage bracket 121. As the vertical transfer rack 1 continues to operate, the storage bracket 121 can continue to hold the arrester 100 until the arrester 100 is completely separated from the buffer rack 21. At the same time, the next arrester 100 on the buffer rack 21 automatically rolls down to the loading position due to gravity.

[0070] In step 3, when the vertical transfer frame 1 drives the arrester 100 to rotate to the position corresponding to the detection mechanism 3, since the two contact pieces 33 in the detection mechanism 3 are distributed in an eight-shaped shape, the two contact pieces 33 distributed in an eight-shaped shape can cooperate with the screws at both ends of the arrester 100 to adjust the position of the arrester 100 so that the arrester 100 is located in the middle position of the middle area of ​​the two turntables 11, until the screws at both ends of the arrester 100 can respectively and simultaneously make electrical contact with the two contact pieces 33. At this time, the DC parameter tester 31 can measure the DC parameters of the arrester, and the measurement results of the DC parameters are divided into qualified and unqualified.

[0071] Step 4: When the measurement result of the DC parameter of the arrester 100 is unqualified, the telescopic drive member 432 is started and the piston rod is retracted, so as to drive the lever 42 to switch from the first position to the second position (the initial position of the lever 42 is the first position, at which time the piston rod of the telescopic drive member 432 is in an extended state) through the connecting rod 434, the crank 433 and the rotating shaft 431, and the arrester can roll down to the placement rack 41 along the lever 42; thereafter, the piston rod of the telescopic drive member 432 is reset. When the measurement result of the DC parameter of the arrester 100 is qualified, the telescopic drive member 432 does not perform any action.

[0072] In step 5, the arrester 100 with qualified DC parameter test results is transferred to the material blocking rod 52 via the vertical transfer rack 1, and can roll along the material blocking rod 52 to the unloading conveyor line 51, and can be transported to the next process via the unloading conveyor line 51.

[0073] To sum up, in a lightning arrester DC parameter testing device provided by the present invention, the first end of the loading rack 2 extends between the two turntables 11, and the supporting port of the bracket 12 is set to always face upward, so that each group of the brackets 12 can cooperate with the screws at both ends of the lightning arrester 100 on the loading rack 2 to lift and load the lightning arrester 100 to the vertical transfer rack 1. After the detection mechanism 3 detects the DC parameters of the lightning arrester 100, the first unloading mechanism 4 and the second unloading mechanism 5 can respectively unload the lightning arresters 100 with two kinds of detection results, thereby realizing the automated detection of the lightning arrester 100 and improving the detection efficiency of the DC parameters of the lightning arrester 100.

[0074] It should be noted that although the present invention is disclosed as above by specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
