Description

Technical Field

[0001] The present invention relates to the technical field of power safety tool detection, and particularly to a power safety tool detection device. Background Art

[0002] At present, an insulating rod is a unified name for insulating tools dedicated to the power system, and can be used for live working, live maintenance, and live repair tools. It is mainly an insulating tool with end fittings made of an insulating tube or an insulating rod. Due to the particularity of the use of the insulating rod, its insulation performance must be clearly detected before use, otherwise major safety accidents will occur. Therefore, it is very necessary to detect each insulating rod one by one.

[0003] The current detection methods include: insulation resistance test, which is usually carried out using a megohmmeter. During the test, the two test electrodes of the megohmmeter are respectively contacted with both ends of the insulating rod, and then the reading of the megohmmeter is read. If the insulation resistance value is less than the specified value, it needs to be replaced or repaired in time; or power frequency withstand voltage test, which is usually carried out using a power frequency withstand voltage test device. During the test, both ends of the insulating rod are respectively connected to the high-voltage output terminal and the grounding terminal of the power frequency withstand voltage test device, and then the test voltage is gradually increased until the specified test voltage value is reached. During the test, it is necessary to observe whether there are phenomena such as breakdown and flashover of the insulating rod. If phenomena such as breakdown and flashover are found, it needs to be replaced or repaired in time.

[0004] An insulating rod insulation detection device with the publication number of CN116449160A in the prior art includes a detection frame, a cross bar, a rod section clamping mechanism, a rod end fixing mechanism, and a power-on test mechanism; a plurality of cross bars are vertically arranged on the detection frame, and each cross bar is horizontally installed on the detection frame; a plurality of rod section clamping mechanisms are arranged along the length direction of the cross bar; the rod end fixing mechanism is installed above the plurality of cross bars on the detection frame, and the rod end fixing mechanism is used to fix the top end of the insulating rod clamped by the plurality of rod section clamping mechanisms; the power-on test mechanism is used to simultaneously touch and power both ends of all insulating rods. This application has the effect of improving the problem of low measurement efficiency when measuring the insulation of insulating rods.

[0005] Insulating rods are mass-produced. If the above prior art is used to detect the insulation of insulating rods, this detection method cannot meet the detection requirements, and this detection method is inefficient; and currently, there are few or no detection methods that cooperate with the insulating rod and the assembly line on the market. If this method is used for detection, it can meet the detection of a large number of insulating rods and can effectively improve the efficiency; for this reason, this application proposes a power safety tool detection device that can cooperate with the insulating rod and the assembly line for detection. Summary of the Invention

[0006] The object of the present invention is to solve the above technical problems, and a detection device for electric power safety tools is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A detection device for electric power safety tools, including a base, on which four support columns are fixedly connected, and the upper ends of the four support columns are fixedly connected with a support plate:

[0009] Two driving rollers rotatably installed on the base, a transmission belt is sleeved on the two driving rollers, an elastic rubber belt is fixedly connected to the outside of the transmission belt, and a plurality of insulating rod placement grooves are evenly distributed on the rubber belt. Two support rollers are installed on the base, and the support rollers are in contact with the transmission belt. Two cylinders that can move synchronously are installed on the support plate, and the two cylinders are located between the two support rollers. The two cylinders are in contact with the rubber belt and make the rubber belt concave into an arc shape. A plurality of limiting grooves are provided on the outer walls of the two cylinders. The limiting grooves are arranged opposite to the insulating rod placement grooves and enclose a circular cavity capable of clamping the insulating rod. Two metal elastic sheets capable of abutting against the end of the insulating rod are installed in the limiting grooves. An insulation resistance measuring instrument connected to the metal elastic sheet is installed on one of the cylinders. The transmission belt is driven by the driving roller to rotate, driving the insulating rod to move. Cooperating with the two cylinders, the insulating rod on the rubber belt can be clamped and the metal elastic sheet can be abutted against the insulating rod, so as to perform resistance detection on the insulating rod.

[0010] Preferably, two first brackets are installed on the base, the driving roller is rotatably installed on the first bracket, and a first motor is installed on one of the first brackets. The output end of the first motor is fixedly connected to the driving roller coaxially.

[0011] Preferably, two second brackets are installed on the base, and the support roller is rotatably installed on the second bracket.

[0012] Preferably, it further includes an automatic feeding mechanism. The automatic feeding mechanism includes a first strip-shaped groove penetrating through the upper end of the support plate. Two U-shaped plates are slidably connected in the first strip-shaped groove, and the distance between the bottom of the U-shaped plate and the rubber belt is the radius of the insulating rod.

[0013] Preferably, a second strip-shaped groove is provided through the support plate. A cross plate is slidably connected in the second strip-shaped groove. A connecting frame is fixed to the bottom of the cross plate. A circular tube is coaxially fixed to the cylinder. The circular tube penetrates through the connecting frame and is slidably connected to it. A rectangular tube is coaxially fixed to one of the cylinders, and a rectangular block is coaxially fixed to the other cylinder. The rectangular block is slidably connected in the rectangular tube.

[0014] Preferably, it further includes a driving mechanism capable of driving the U-shaped plate and the cross-shaped plate to move. The driving mechanism includes two support blocks fixed on the support plate. A second motor is installed on one of the support blocks. The output end of the second motor is fixedly connected to a first screw rod. The other end of the first screw rod is fixed with a second screw rod. The other end of the second screw rod is rotatably connected to the support block. Two movable plates are slidably connected to the support plate. Both ends of the movable plate are fixedly connected to the U-shaped plate and the cross-shaped plate respectively. The first screw rod and the second screw rod respectively penetrate through the movable plate on the same side and are threadedly connected thereto.

[0015] Preferably, the thread directions of the first screw rod and the second screw rod are opposite.

[0016] Preferably, it further includes a mechanism for removing unqualified insulating rods. The mechanism for removing unqualified insulating rods includes a fixed frame installed on one of the connecting frames. A driving member is installed on the fixed frame. A push block is fixed at the output end of the driving member. The driving member is connected to the insulation resistance measuring instrument through a controller.

[0017] Preferably, the plurality of limiting grooves are annularly and arrayedly distributed on the outer wall of the cylinder.

[0018] Preferably, the driving member is a cylinder or an electric push rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. When the conveyor belt drives the rubber belt to move, when the insulating rod is opposite to the insulating rod placement groove, the insulating rod at this time falls into the insulating rod placement groove and is taken away. Then the insulating rod abuts against the rubber belt again. In this way, automatic feeding is realized without manual participation. Due to the setting of the insulating rod placement groove and the material of the rubber belt, the friction force between the insulating rod and the rubber belt can be increased, so that the insulating rod is not easily moved and offset during the conveying process, and automatic feeding of the insulating rod is realized.

[0021] 2. The rubber belt located below the cylinder can always abut against the cylinder. Since the friction force of the rubber belt can drive the cylinder to rotate, and when the cylinder rotates, the limiting groove and the insulating rod placement groove are opposite to each other one by one and move synchronously. Without providing additional power for the rotation of the cylinder, it can also ensure that the limiting groove and the insulating rod placement groove are stably opposite, providing a guarantee for subsequent insulating rod detection.

[0022] 3. When the insulating rod placement groove with the insulating rod moves to the cylinder, the upper end of the insulating rod is located in the limiting groove at this time. The insulating rod is completely located between the insulating rod placement groove and the limiting groove. At this time, the metal elastic sheet abuts against the insulating rod. The resistance of the insulating rod can be detected by the insulation resistance measuring instrument. If the insulation resistance value is less than the specified value, it means that the insulating rod is unqualified. If the insulation resistance value is greater than the specified value, it means that it is qualified.

[0023] 4. When the insulating rod is unqualified, the insulation resistance measuring instrument transmits a signal to the controller, and the controller controls the driving member to work to drive the pushing block to push the insulating rod to move. When the insulating rod is placed in the insulating rod placement groove, one end thereof is close to the pushing block but does not abut against it. Therefore, the driving member can drive the pushing block to quickly push the insulating rod without the first motor stopping working, so that the other end of the insulating rod is longer than other qualified insulating rods, so that the staff can remove the unqualified ones, realizing the separation of qualified products and unqualified products.

[0024] 5. It can detect the insulating rod in a pipeline manner, greatly improving the detection efficiency, and can also ensure that each insulating rod can be detected to ensure the safety during the use of the insulating rod, providing safety protection for users.

[0025] 6. The second motor works to drive the first screw rod and the second screw rod to rotate. Since the movable plate cannot rotate on the support plate and the thread directions of the first screw rod and the second screw rod are opposite, when the first screw rod and the second screw rod rotate, the two movable plates can move relatively or closer, thereby driving the U-shaped plate and the cross plate to move. Controlling the distance between the two U-shaped plates can control the feeding of insulating rods of different lengths; the movement of the cross plate drives the connecting frame and the cylinder to move, and the cylinder can move synchronously with the U-shaped plate, so that insulating rods of different lengths can be detected.

[0026] In summary, the present invention realizes the automatic feeding and pipeline detection of insulating rods, improves the detection efficiency, ensures that each insulating rod is detected, guarantees the use safety, does not require additional power for the rotation of the cylinder, ensures that the limiting groove and the insulating rod placement groove are stably opposite, can quickly identify and separate unqualified insulating rods, is convenient for processing, and sets the adjustable distance between the U-shaped plates and the position of the cylinder to adapt to the detection of insulating rods of different lengths.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Refer to Figures 1 - 6 , a power safety tool detection device, including a base 1, on which four support columns 2 are fixedly connected, and at the upper ends of the four support columns 2, a support plate 3 is fixedly connected:

[0036] Two driving rollers 12 rotatably installed on the base 1, a drive belt 20 is sleeved on the two driving rollers 12, two first brackets 11 are installed on the base 1, the driving rollers 12 are rotatably installed on the first brackets 11, and a first motor 13 is installed on one of the first brackets 11. The output end of the first motor 13 is fixedly connected to the driving roller 12 coaxially. In this way, when the first motor 13 works, it drives the driving roller 12 to rotate, and under the transmission of the drive belt 20, the other driving roller 12 can be driven to rotate, so as to realize the stable rotation of the drive belt 20.

[0037] The outer part of the drive belt 20 is fixedly connected with a rubber belt 14, and the rubber belt 14 has a certain thickness. In this way, a plurality of insulating rod placement grooves 15 evenly distributed can be provided on the rubber belt 14. The insulating rod placement grooves 15 penetrate through both sides of the rubber belt 14, and the insulating rod placement grooves 15 are arc-shaped grooves to ensure that the insulating rods can be stably placed in the insulating rod placement grooves 15.

[0038] Two support rollers 18 are installed on the base 1, two second brackets 24 are installed on the base 1, the support rollers 18 are rotatably installed on the second brackets 24, and the positions of the support rollers 18 are as Figure 1 , Figure 2As shown in the figure; the supporting roller 18 abuts against the transmission belt 20. Two cylinders 10 that can move synchronously are installed on the supporting plate 3. A second strip-shaped groove 6 is provided through the supporting plate 3. A cross plate 8 is slidably connected in the second strip-shaped groove 6. A connecting frame 7 is fixed to the bottom of the cross plate 8. A circular tube 19 is coaxially fixed to the cylinder 10. An electrical rotary joint can be installed on the circular tube 19, so that multiple insulation resistance measuring instruments 28 can be powered, or the insulation resistance measuring instrument 28 has a separate built-in power supply.

[0039] The circular tube 19 passes through the connecting frame 7 and is slidably connected thereto. A rectangular cylinder 27 is coaxially fixed to one of the cylinders 10, and a rectangular block 29 is coaxially fixed to the other cylinder 10. The rectangular block 29 is slidably connected in the rectangular cylinder 27. In this way, when the cylinder 10 rotates to drive the rectangular cylinder 27 or the rectangular block 29 to rotate, the other cylinder 10 can be driven to rotate.

[0040] It further includes an automatic feeding mechanism. The automatic feeding mechanism includes a first strip-shaped groove 4 provided through the upper end of the supporting plate 3. Two U-shaped plates 5 are slidably connected in the first strip-shaped groove 4. The distance between the bottom of the U-shaped plate 5 and the rubber belt 14 is the radius of the insulating rod. When the transmission belt 20 drives the rubber belt 14 to move, the insulating rod located between the two U-shaped plates 5 abuts against the rubber belt 14 due to gravity. When the insulating rod is opposite to the insulating rod placement groove 15, the insulating rod at this time falls into the insulating rod placement groove 15 and is taken away, so as to realize automatic feeding.

[0041] It further includes a driving mechanism that can drive the U-shaped plate 5 and the cross plate 8 to move. The driving mechanism includes two support blocks 21 fixed to the supporting plate 3. A second motor 31 is installed on one of the support blocks 21. The output end of the second motor 31 is fixedly connected with a first screw rod 22. The other end of the first screw rod 22 is fixed with a second screw rod 23. The other end of the second screw rod 23 is rotatably connected to the support block 21. Two movable plates 9 are slidably connected to the supporting plate 3. The two ends of the movable plate 9 are respectively fixed to the U-shaped plate 5 and the cross plate 8. The first screw rod 22 and the second screw rod 23 respectively pass through the movable plate 9 on the same side and are threadedly connected thereto. When the second motor 31 works to drive the first screw rod 22 and the second screw rod 23 to rotate, since the movable plate 9 cannot rotate on the supporting plate 3, and the thread directions of the first screw rod 22 and the second screw rod 23 are opposite, therefore, when the first screw rod 22 and the second screw rod 23 rotate, the two movable plates 9 can move relatively or closer, thereby driving the U-shaped plate 5 and the cross plate 8 to move. Controlling the distance between the two U-shaped plates 5 can control the feeding of insulating rods of different lengths; the movement of the cross plate 8 drives the connecting frame 7 and the cylinder 10 to move, and the cylinder 10 can move synchronously with the U-shaped plate 5, so that insulating rods of different lengths can be detected.

[0042] Two cylinders 10 are located between two support rollers 18. The two cylinders 10 are in contact with the rubber belt 14 and cause the rubber belt 14 to be concave in an arc shape. A plurality of limiting grooves 25 are provided on the outer walls of the two cylinders 10. The limiting grooves 25 are arranged opposite to the insulating rod placement grooves 15 and enclose a circular cavity capable of clamping the insulating rod. Two metal elastic pieces 26 capable of abutting against the end of the insulating rod are installed in the limiting grooves 25, and the metal elastic pieces 26 can abut against the insulating rod; an insulating resistance measuring instrument 28 connected to the metal elastic piece 26 is installed on one of the cylinders 10. The transmission belt 20 is driven by the transmission roller 12 to rotate and drive the insulating rod to move. Cooperating with the two cylinders 10, the insulating rod on the rubber belt 14 can be clamped and the metal elastic piece 26 can abut against the insulating rod, so as to detect the resistance of the insulating rod.

[0043] It further includes a mechanism for removing unqualified insulating rods. The mechanism for removing unqualified insulating rods includes a fixed frame 16 installed on one of the connecting frames 7. A driving member 17 is installed on the fixed frame 16. The driving member 17 is a cylinder or an electric push rod; a push block 30 is fixed to the output end of the driving member 17. The driving member 17 is connected to the insulating resistance measuring instrument 28 through a controller. When an unqualified insulating rod is detected, the insulating resistance measuring instrument 28 will transmit a signal to the controller, and the controller controls the driving member 17 to work to drive the push block 30 to push the insulating rod to move, so that the other end of the insulating rod is longer than other qualified insulating rods, so that the staff can take the unqualified insulating rod.

[0044] When the present invention is in use, the staff places the insulating rod between the two U-shaped plates 5. Due to the gravity of the insulating rod, the lowermost insulating rod abuts against the rubber belt 14. Then, the first motor 13 is started, and the first motor 13 works to drive the transmission roller 12 to rotate. Under the transmission of the transmission roller 12 and the transmission belt 20, the rubber belt 14 moves stably; when the transmission belt 20 drives the rubber belt 14 to move, when the insulating rod is opposite to the insulating rod placement groove 15, the insulating rod at this time falls into the insulating rod placement groove 15 and is taken away. Then the insulating rod abuts against the rubber belt 14 again, so as to realize automatic feeding without manual participation. Due to the setting of the insulating rod placement groove 15 and the material of the rubber belt 14, the friction force with the insulating rod can be increased, so that the insulating rod is not easy to move and deviate during the conveying process;

[0045] At this time, the rubber belt 14 located below the cylinder 10 can always abut against the cylinder 10. Due to the friction force of the rubber belt 14, the cylinder 10 can be driven to rotate. When the cylinder 10 rotates, the limiting groove 25 and the insulating rod placement groove 15 are opposite to each other one by one and move synchronously. Without providing additional power for the rotation of the cylinder 10, it can also ensure that the limiting groove 25 and the insulating rod placement groove 15 are stably opposite;

[0046] When the insulating rod placement slot 15 with the insulating rod placed therein moves to the cylinder 10, the upper end of the insulating rod is located in the limiting slot 25, and the insulating rod in the group is completely located between the insulating rod placement slot 15 and the limiting slot 25. At this time, the metal spring 26 is against the insulating rod, and the insulation resistance measuring instrument 28 can be used to detect the resistance of the insulating rod. If the insulation resistance value is less than the specified value, it means that the insulating rod is unqualified, and if the insulation resistance value is greater than the specified value, it means that it is qualified;

[0047] When the insulating rod is unqualified, the insulation resistance measuring instrument 28 will transmit a signal to the controller, and the controller controls the driving member 17 to drive the push block 30 to push the insulating rod to move. When the insulating rod is placed in the insulating rod placement slot 15, one end of the insulating rod is close to the push block 30 but not against it, so that the driving member 17 drives the push block 30 to quickly push the insulating rod without stopping the first motor 13, so that the other end of the insulating rod is longer than other qualified insulating rods. After being tested, they are transported backwards one by one through the rubber belt 14, and the staff removes the unqualified ones, and the qualified ones follow the rubber belt 14 to move, and finally leave the insulating rod placement slot 15, and the qualified insulating rods can be collected through the collection box;

[0048] As mentioned above, the insulating rods can be inspected in an assembly line manner, which greatly improves the efficiency of the inspection and can also ensure that each insulating rod can be inspected to ensure the safety of the insulating rods when in use, providing safety protection for users.

[0049] Since the length of each section of the insulating rod is different, the present invention can also perform adaptive detection on insulating rods of different lengths;

[0050] Specifically: the second motor 31 drives the first screw 22 and the second screw 23 to rotate. Since the movable plate 9 cannot rotate on the support plate 3, and the thread directions of the first screw 22 and the second screw 23 are opposite, the first screw 22 and the second screw 23 can realize relative or close movement of the two movable plates 9 when they rotate, thereby driving the U-shaped plate 5 and the cross plate 8 to move. Controlling the distance between the two U-shaped plates 5 can control the loading of insulating rods of different lengths; the movement of the cross plate 8 drives the connecting frame 7 and the cylinder 10 to move, and the cylinder 10 can move synchronously with the U-shaped plate 5, so that insulating rods of different lengths can be detected.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
