Description

Technical Field

[0001] The invention belongs to the technical field of cable detection, and in particular relates to a power line detection device. Background Art

[0002] The power cord, also known as the plug cord or connecting cord, is a key component of power transmission and is widely used in various electrical equipment. Its structure usually includes a conductive core, an insulating layer and a protective outer sheath. In order to ensure the safety and reliability of the power cord, manufacturers pay special attention to its quality inspection before leaving the factory.

[0003] Traditional power cord testing covers multiple items, mainly including polarity testing: verifying whether the connection polarity between the power cord plug and the socket is correct to prevent electrical safety accidents caused by misconnection; conductivity testing: confirming the connectivity of the internal circuit of the power cord to avoid power outages caused by circuit breakage; current carrying capacity testing: evaluating the working performance of the power cord under rated current to prevent overload from causing overheating or even fire; inter-pole high voltage testing: applying high voltage between different conductors of the power cord to test its insulation performance to ensure that it can still work safely under abnormal voltage fluctuations, and also including insulation performance testing and outer sheath leakage copper detection, etc. The current power cord testing methods mainly have the following shortcomings.

[0004] Early detection methods relied on manual operation, inserting the power cords to be tested into different dedicated detection modules one by one. This method is equivalent to repeated operations on each power cord, and the number of operations is the product of the number of power cords and the test items, resulting in low detection efficiency, high labor costs, and prone to human errors, affecting the accuracy of the test results.

[0005] In order to improve the detection efficiency, the existing technology has developed automated detection equipment. These devices usually adopt an assembly line design, arranging different detection modules at intervals. The power cord to be tested only needs to be inserted once, and then it can be transported to each detection module in turn by the transmission mechanism to automatically complete the detection. Although this method greatly improves the efficiency compared to manual detection, due to the integration of multiple detection modules on the line, the length of the assembly line increases, resulting in a large size of the equipment, occupying valuable production site space, and increasing the manufacturing cost and maintenance difficulty of the equipment.

[0006] Since the power cord itself has a certain flexibility and length, during the assembly line inspection process, the plug end and the tail end of the power cord need to be fixed to the power port and the inspection port respectively. When the power cord length exceeds a certain limit, it is easy to get tangled and hooked during the transmission process, which not only affects the normal operation of the equipment, but also may cause damage to the power cord, increasing the difficulty of subsequent processing. Summary of the invention

[0007] In view of the above situation, the present invention provides a power cord detection device, which allows the power cord to be automatically detected in a circular parallel manner through the detection modules arranged in a circular manner, thereby shortening the length of the assembly line, saving production space, and significantly improving the detection efficiency. The innovative length adjustment mechanism effectively solves the problem of power cord winding and hooking, and is suitable for power cords of various lengths.

[0012] Furthermore, one end of the cylindrical roller is in a close sliding fit relationship with the first vertical slide groove, the second vertical slide groove and the spiral slide groove.

[0013] Furthermore, the edges of the power supply disk and the connection disk are both provided with limit rods extending outward in a circumferential array, and the limit rods are vertically slidably penetrated by sliding columns.

[0014] Furthermore, the bidirectional adjustment and debugging mechanism includes a screw and a locking nut, the upper end of the screw vertically passes through the center of the power disk and is threadedly connected to the power disk, the lower end of the screw is engaged and rotatably connected to the center of the connecting disk, and a rotating rod is fixedly provided in a circular array in the middle part of the screw, and the locking nuts are respectively arranged on the outside of a limit rod on the power disk and the connecting disk, and the locking nut can contact the sliding column during the threaded movement with the limit rod.

[0015] Furthermore, the detection disk is coaxially fixed on the upper end of the cylindrical cam, and structural columns are fixedly arranged in a circular array between the detection disk and the cylindrical cam.

[0016] Furthermore, the electrical connection component includes a plug connection seat, a wire tail connection seat and a detection connection seat, the plug connection seat is fixedly installed on the power disk, the plug connection seats are distributed in an array along the axis of the power disk, the jack of the plug connection seat faces downward, the lead terminals of the plug connection seat face upward and are connected in parallel with the total power supply, the number of the plug connection seats is equal to the number of the first vertical slide grooves, the wire tail connection seat is fixedly installed on the connection disk, the projections of the wire tail connection seat and the plug connection seat on the horizontal plane coincide, the pins of the wire tail connection seat face upward, the lead terminals of the wire tail connection seat face downward, the detection connection seat is fixedly installed on the detection disk, the jack of the detection connection seat faces upward, the lead terminals of the detection connection seat face downward, and the jacks of all detection connection seats can face the lead terminals of all wire tail connection seats after the detection disk stops rotating.

[0017] Furthermore, detection units are fixedly provided in a circular array on the lower side of the detection disk, and the detection units are electrically connected to the lead terminals of the detection connection socket.

[0018] Furthermore, when the output end of the telescopic power cylinder is located at the top, the cylindrical roller is located at the lower end of the second vertical slide groove and the lead terminal of the wire tail connection seat is completely inserted into the socket of the detection connection seat to achieve electrical connection; when the cylindrical roller is located at the lower end of the spiral slide groove, the lead terminal of the wire tail connection seat is separated from the socket of the detection connection seat; when the cylindrical roller passes through the spiral slide groove and is located at the upper end position of the first vertical slide groove, the lead terminal of the wire tail connection seat is opposite to the socket of the detection connection seat and the output end of the telescopic power cylinder is located at the bottom.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The three-stage cam detection mechanism adopted in the present invention cleverly decomposes the detection process of the power cord into three stages: insertion detection, separation and rotation detection unit. This design realizes automatic parallel detection of the power cord. Specifically, when the telescopic power cylinder moves upward, the wire tail connection seat is connected with the detection connection seat to perform electrical detection. When the telescopic power cylinder retracts, the cylindrical roller is blocked by the bottom of the first vertical slide groove and enters the spiral slide groove, forcing the cylindrical cam to rotate and drive the detection unit to rotate to the next power cord position. Thereafter, the telescopic power cylinder moves upward again to perform the next detection. This cyclic three-stage movement allows multiple power cords to be detected in different detection units at the same time, without the need to perform them one by one as in traditional manual assembly line detection, which greatly improves the detection efficiency and reduces the detection time. At the same time, since the various detection units are arranged in a ring, the length of the assembly line is shortened, thereby reducing the volume of the equipment and saving valuable production site space.

[0020] (2) The bidirectional adjustment and debugging mechanism designed in the present invention can independently adjust the height of the power supply plate and the connecting plate through the cooperation of the screw, the locking nut and the rotating rod. This design enables the device to adapt to power cords of different lengths. By adjusting the height of the connecting plate, it can ensure that the wire tail connector can be accurately connected to the detection connector during the detection process. By adjusting the height of the power supply plate, it can adapt to the length of the power cord and avoid the problems of winding and hooking caused by the power cord being too long. This flexible adjustment method makes the device more widely applicable and can meet the detection requirements of different types of power cords, thereby improving the versatility and practicality of the equipment.

[0021] (3) During the detection process, the connection and separation actions between the wire tail connector and the detection connector are clear and distinct. During the rotation stage, the wire tail connector and the detection connector are completely disconnected, avoiding damage to the contact parts. In addition, since the entire device only requires a single power source, the telescopic power cylinder, to drive it, the structure is simple. Compared with traditional multi-drive assembly line detection equipment, the structure of the device is greatly simplified, the manufacturing cost and maintenance difficulty are reduced, and fewer moving parts also mean lower failure rates and more convenient maintenance operations.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention proposes a power line detection device, including a base 1, a telescopic power cylinder 2 with an output end facing upward is fixedly provided on the upper side of the base 1, a three-stage cam detection mechanism 3 is provided on the output end of the telescopic power cylinder 2, a detection disk 4 is provided on the upper side of the three-stage cam detection mechanism 3, a connecting disk 6 and a power disk 7 are coaxially provided above the detection disk 4 from bottom to top, a plurality of sliding columns 5 for vertical limited sliding of the power disk 7 and the connecting disk 6 are vertically provided around the detection disk 4 on the base 1, a two-way adjustment and debugging mechanism 8 is provided on the power disk 7 and the connecting disk 6, and an electrical connection component 9 is provided on the power disk 7, the connecting disk 6 and the detection disk 4.

[0035] Optionally, the telescopic power cylinder 2 may be a pneumatic cylinder or a hydraulic cylinder, or may be a mechanical structure capable of performing reciprocating telescopic motion. It is understandable that the output end of the telescopic power cylinder 2 can reciprocate and telescope to provide power.

[0036] Among them, the three-stage cam detection mechanism 3 includes a clamping shaft 31, a cylindrical cam 32 and a cylindrical roller 36 matching the cylindrical cam 32. The clamping shaft 31 is coaxially fixed on the output end of the telescopic power cylinder 2, and the cylindrical cam 32 is engaged and rotatably arranged on the outside of the clamping shaft 31. It can be understood that through the engaging and rotating connection method, the cylindrical cam 32 can be synchronously lifted and lowered with the output end of the telescopic power cylinder 2 and can rotate relatively. The cylindrical roller 36 is arranged on both sides of the cylindrical cam 32 and points to the axis of the cylindrical cam 32. It can be understood that through the matching connection between the cylindrical rollers 36 on both sides and the cylindrical cam 32, the operation process of the cam matching structure is more stable.

[0037] Among them, a first vertical slide groove 33 is opened on the cylindrical cam 32, and the first vertical slide grooves 33 are opened in a circular array with equal depth on the surface of the cylindrical cam 32. Only one spiral slide groove 34 with the same spiral direction is arranged between each two adjacent first vertical slide grooves 33. The spiral slide groove 34 is spirally opened on the surface of the cylindrical cam 32. One end of the spiral slide groove 34 is connected to the lower end of the first vertical slide groove 33, and the other end of the spiral slide groove 34 is connected to the upper end of another first vertical slide groove 33. A second vertical slide groove 35 is opened at the lower end of the first vertical slide groove 33 in parallel. The second vertical slide groove 35 is opened on the surface of the cylindrical cam 32 with equal depth. The bottom of the lower end of the spiral slide groove 34 is lower than the bottom of the first vertical slide groove 33 and is the same depth as the bottom of the second vertical slide groove 35. The bottom of the upper end of the spiral slide groove 34 is higher than the bottom of the first vertical slide groove 33.

[0038] The three-stage cam detection mechanism 3 further includes a bracket 39 and a sleeve 38. The bracket 39 is arranged on both sides of the telescopic power cylinder 2. The bracket 39 is fixedly connected to the base 1. The sleeve 38 is fixedly arranged on the inner side of the bracket 39. The sleeve 38 is slidably sleeved on the outer side of the cylindrical roller 36. A compression spring 37 is arranged in the sleeve 38. The two ends of the compression spring 37 are respectively fixedly connected to the closed end of the sleeve 38 and the cylindrical roller 36. One end of the cylindrical roller 36 is connected to the first vertical slide groove 33, the second vertical slide groove 35 and the spiral slide groove 3 4 is in a close sliding fit relationship. It can be understood that, by arranging the compression spring 37, the end of the cylindrical roller 36 is always in close contact with the groove bottoms of the first vertical slide groove 33, the second vertical slide groove 35 and the spiral slide groove 34 under the thrust of the compression spring 37, and through the depth relationship of the groove bottoms of the first vertical slide groove 33, the second vertical slide groove 35 and the spiral slide groove 34, the telescopic power cylinder 2 drives the cylindrical cam 32 to make regular movements under the limit of the cylindrical roller 36 whose vertical position remains unchanged.

[0039] Among them, the edges of the power supply plate 7 and the connecting plate 6 are both provided with limit rods 71 ​​extending outward in a circular array, and the limit rods 71 ​​are vertically slid through by the sliding column 5, so that the power supply plate 7 and the connecting plate 6 can only move vertically up and down.

[0040] Among them, the two-way adjustment and debugging mechanism 8 includes a screw 81 and a locking nut 83. The upper end of the screw 81 vertically passes through the center of the power disk 7 and is threadedly connected to the power disk 7. The lower end of the screw 81 is engaged and rotatably connected to the center of the connecting disk 6. Through the engaged and rotatable connection, the screw 81 and the connecting disk 6 can only move up and down synchronously but can rotate relative to each other. A rotating rod 82 is fixedly arranged in a circular array in the middle part of the screw 81 to facilitate the rotation of the screw 81. The locking nuts 83 are respectively arranged on the outside of a limit rod 71 on the power disk 7 and the connecting disk 6. The locking nut 83 can contact the sliding column 5 during the threaded movement with the limit rod 71. It can be understood that the power disk 7 and the connecting disk 6 are fixed in the vertical direction by tightening the locking nut 83.

[0041] The detection disk 4 is coaxially fixed on the upper end of the cylindrical cam 32, and structural columns 41 are fixedly arranged in a circumferential array between the detection disk 4 and the cylindrical cam 32. The structural columns 41 are arranged to prevent the detection disk 4 carrying a load from being deformed.

[0042] Among them, the electrical connection component 9 includes a plug connection seat 91, a wire tail connection seat 92 and a detection connection seat 93, all of which are standard components commonly used in the field of wire connection and are used to transmit electrical signals. The plug connection seat 91 is fixedly penetrated on the power supply disk 7, and the plug connection seat 91 is distributed in a circular array along the axis of the power supply disk 7. The jack of the plug connection seat 91 faces downward, and the lead terminal of the plug connection seat 91 faces upward and is connected in parallel with the main power supply, thereby providing a power source for power line detection. The number of plug connection seats 91 is equal to the number of first vertical slide slots 33, so that in the same circular array arrangement, if the number of plug connection seats 91 is equal to the number of first vertical slide slots 33 Only when they are equal can the angle distribution be the same, and only then can it be ensured that the detection connection seat 93 and the wire tail connection seat 92 can match the position every time the detection disk 4 rotates once. The wire tail connection seat 92 is fixedly penetrated on the connecting disk 6, and the projections of the wire tail connection seat 92 and the plug connection seat 91 on the horizontal plane coincide with each other. The pin of the wire tail connection seat 92 faces upward, and the lead terminal of the wire tail connection seat 92 faces downward. The detection connection seat 93 is fixedly penetrated on the detection disk 4, and the jack of the detection connection seat 93 faces upward, and the lead terminal of the detection connection seat 93 faces downward. After the detection disk 4 stops rotating, the jacks of all detection connection seats 93 can face the lead terminals of all wire tail connection seats 92.

[0043] Among them, the detection units 42 are fixedly provided in a circular array on the lower side of the detection disk 4, and the detection units 42 are electrically connected to the lead terminals of the detection connecting socket 93. The number of types of the detection units 42 is equal to the number of the first vertical slide grooves 33. It can be understood that the device ultimately determines the number of the first vertical slide grooves 33, the plug connecting socket 91, the tail connecting socket 92 and the detection connecting socket 93 through the required number of types of the detection units 42.

[0044] Among them, when the output end of the telescopic power cylinder 2 is located at the top, the cylindrical roller 36 is located at the lower end of the second vertical slide groove 35 and the lead terminal of the wire tail connection seat 92 is completely inserted into the socket of the detection connection seat 93 to realize electrical connection; when the cylindrical roller 36 is located at the lower end of the spiral slide groove 34, the lead terminal of the wire tail connection seat 92 is separated from the socket of the detection connection seat 93; when the cylindrical roller 36 passes through the spiral slide groove 34 and is located at the upper end position of the first vertical slide groove 33, the lead terminal of the wire tail connection seat 92 is opposite to the socket of the detection connection seat 93 and the output end of the telescopic power cylinder 2 is located at the bottom.

[0045] When in use, firstly, it is necessary to adjust the height of the connecting plate 6 to realize the smooth detection of the device, and then tighten the locking nut 83 corresponding to the power supply plate 7 so that the locking nut 83 is in full contact with the sliding column 5 to fix the power supply plate 7. At this time, the locking nut 83 corresponding to the connecting plate 6 is in a released state, and then the rotating rod 82 is rotated, and the screw 81 and the power supply plate 7 are threadedly moved. Since the power supply plate 7 is fixed, the screw 81 will be passively lifted and lowered, and then the lifting and lowering of the connecting plate 6 will be driven by the engaging and rotating connection relationship with the connecting plate 6, and the height of the connecting plate 6 is adjusted to a suitable position so that when the output end of the telescopic power cylinder 2 is at the top, the lead terminal of the wire tail connecting seat 92 can be The connecting plate 6 is adjusted to a desired length and the locking nut 83 corresponding to the connecting plate 6 is tightened and fixed, and the locking nut 83 corresponding to the power supply plate 7 is released. The rotating rod 82 is rotated. Since the screw rod 81 is restricted by the connecting plate 6 at this time, the threaded movement of the screw rod 81 and the power supply plate 7 will drive the power supply plate 7 to rise and fall until the distance between the power supply plate 7 and the connecting plate 6 matches the length of the power cord, thereby avoiding the phenomenon described in the background technology that the power cord is easily bent, coiled and hooked when the power cord is too long and the two fixed ends are short. Subsequently, the locking nut 83 corresponding to the power supply plate 7 is tightened and fixed, thereby realizing the debugging and adjustment of the device.

[0046] The power cord to be tested is placed all over the plug connector 91 and the wire tail connector 92, the plug of the power cord is inserted into the jack of the plug connector 91, and the jack at the tail end of the power cord is inserted into the pin of the wire tail connector 92. At this time, the lead terminal of the plug connector 91 is connected in parallel with the main power supply and the main power supply is turned on, and then the telescopic power cylinder 2 is turned on. The telescopic power cylinder 2 performs regular telescopic movement under the control of the control system. When the output end of the telescopic power cylinder 2 moves upward, it drives the card shaft 31, the cylindrical cam 32, the detection disk 4 and the detection connector 93 to move upward synchronously until the output end of the telescopic power cylinder 2 is at the top, and the wire tail connector The lead terminal of 92 is fully inserted into the jack of the detection connection seat 93 to achieve electrical connection, so that different power lines are electrically tested in different detection units 42, and the detection information is uploaded to the system. At this time, the cylindrical roller 36 is located at the lower end of the second vertical slide groove 35, and then the output end of the telescopic power cylinder 2 begins to retract, driving the cylindrical cam 32 to move downward, and synchronously driving the detection disk 4 to move downward so that the lead terminal of the wire tail connection seat 92 is separated from the jack of the detection connection seat 93. Since the cylindrical roller 36 is always in a stationary state, the cylindrical cam 32 moves downward so that the cylindrical roller 36 reaches the upper end position of the second vertical slide groove 35 Due to the action of the compression spring 37, the end of the cylindrical roller 36 is always in close contact with the bottom of the second vertical slot 35, and because the bottom of the second vertical slot 35 is lower than the bottom of the first vertical slot 33, the bottom of the second vertical slot 35 is as deep as the bottom of the lower end of the spiral slot 34. Therefore, during the continuous descent of the output end of the telescopic power cylinder 2, the cylindrical roller 36 is blocked by the bottom of the first vertical slot 33 and is forced to enter the spiral slot 34. The movement of the cylindrical cam 32 is reflected in that the cylindrical cam 32 begins to be forced to rotate, thereby driving the detection connection seat 93 to perform a circular motion until the cylindrical roller 36 is When the power cord passes through the spiral chute 34 and is located at the upper end of the first vertical chute 33, the lead terminal of the wire tail connector 92 faces the jack of the next detection connector 93. At this time, the output end of the telescopic power cylinder 2 stops retracting and starts to move upward. Since the cylindrical roller 36 is blocked by the bottom of the upper end of the spiral chute 34 and cannot return to the spiral chute 34 again, the cylindrical cam 32 can only move vertically upward to start the next detection. In the next detection, the same power cord will be detected by another detection unit 42, and then the three-stage detection will be started in a cycle, i.e., the insertion detection, separation and rotation detection unit 42.
