Description

Technical Field

[0001] This utility model is a combined safety tool testing device, belonging to the field of insulation safety tool testing. Background Technology

[0002] Insulating safety tools refer to electrical tools that can directly operate live equipment or come into contact with or may come into contact with live conductors, such as capacitive voltage detectors, insulating rods, and insulating gloves. Their insulation performance is directly related to the personal safety of the operator, therefore, they need to be tested regularly using testing equipment to perform AC withstand voltage tests.

[0003] In existing technologies, different testing methods are required depending on the type of insulating safety tool. For example, when conducting an AC withstand voltage test on insulating gloves, the gloves are placed in a test bucket filled with water, and water is added. Then, a probe is placed in the water inside the gloves. Finally, the high-voltage output lead of the booster is connected to the lead hole connected to the probe, and the grounding device is connected to the grounding terminal fixed to one side of the test bucket. Turning on the AC booster transformer allows for the AC withstand voltage test on the insulating gloves. However, when conducting an AC withstand voltage test on insulating rods, the insulating rods are placed in a metal clamp for fixation. Then, the high-voltage output lead of the booster and the grounding device are connected to the high-voltage terminal and grounding terminal fixed to one side of the metal clamp, respectively. Turning on the AC booster transformer allows for the AC withstand voltage test on the insulating gloves. Therefore, different testing devices are required to test different insulating safety tools, which increases the testing cost. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined safety tool testing device to solve the problem mentioned in the background art that different testing methods are required for different types of insulating safety tools, thus requiring different testing devices to test different insulating safety tools, thereby increasing the testing cost.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined safety tool testing device, comprising two bases, several sleeves fixedly connected to the surface of the bases, an extension rod slidably connected inside the sleeves, locking holes being provided on the surfaces of both the sleeves and the extension rods, locking bolts being threaded into the locking holes, a first testing component being provided at the top of the extension rod, and a second testing component being provided between the two bases.

[0006] Furthermore, the first test assembly includes a mounting plate fixedly connected to the top end of the extension rod. A first clamping seat is sleeved on the surface of the mounting plate, and a second clamping seat is sleeved on the surface of the other mounting plate. A clamping plate is hinged to the top end of both the first and second clamping seats. Limiting grooves are formed on the surfaces of the first and second clamping seats and the clamping plates. An opening and closing plate is fixedly connected to one side of each of the first and second clamping seats and the clamping plate. An opening and closing bolt is internally threaded into the opening and closing plate. A first high-voltage connector is fixedly connected to one side of the first clamping seat, and a first grounding connector is fixedly connected to one side of the second clamping seat.

[0007] Furthermore, the second test assembly includes a connecting plate fixedly connected to one side of the base, a placement plate sleeved on the surface of the connecting plate, a plurality of test barrels disposed within the placement plate, a first mounting rod fixedly connected between two adjacent extension rods of each test barrel, a second mounting rod disposed within the first mounting rod, a plurality of leads fixedly connected to the surface of the second mounting rod, a second high-voltage connector fixedly connected to the top of the second mounting rod, and a second grounding connector fixedly connected to both the placement plate and one side of the test barrel.

[0008] Furthermore, the surface of the extension rod is fixedly connected with a scale on one side of the locking hole, and the surface of the scale is coated with a fluorescent layer.

[0009] Furthermore, the limiting grooves are evenly distributed on the surfaces of the first clamping seat, the second clamping seat, and the clamping plate, and the limiting grooves are in the shape of a "V".

[0010] Furthermore, a storage groove is provided at the bottom of the connecting plate, and a support plate is rotatably connected inside the storage groove.

[0011] The beneficial effects of this utility model are: by pulling the extension rod before performing the AC withstand voltage test, allowing it to slide along the inner wall of the sleeve, the distance between the two bases or the height of the mounting plate can be adjusted according to the specific situation of the tool to be tested. The extension rod can be limited by the locking bolt and locking hole.

[0012] When performing AC withstand voltage tests on tools such as insulating boots, first place the placement plate on top of the connecting plate, then place the second mounting rod on top of the first mounting rod. Next, place the test bucket into the placement plate, then place the insulating boot to be tested into the test bucket, simultaneously placing the lead wire into the insulating boot. Next, connect the high-voltage output lead of the booster device to the second high-voltage connector and connect the grounding device to the second grounding connector. Finally, start the AC booster transformer to perform the AC withstand voltage test on the insulating boot. When performing AC withstand voltage tests on tools such as insulating rods, place the first and second clamping seats onto the surfaces of the two mounting plates respectively, then place the insulating rod into the limiting groove. Next, rotate the clamping plate until it is aligned with the first... The two ends of the insulating rod can be fixed in the first and second clamping seats respectively by contacting the clamping seat or the second clamping seat and using the opening and closing bolts and the opening and closing plate. Next, the output high voltage lead of the step-up device is connected to the first high voltage connector and the grounding device is connected to the first grounding connector. Finally, the AC step-up transformer is started to perform AC withstand voltage test on the insulating rod and other components. Through the above settings, the corresponding test components can be selected according to the actual situation of the safety tool to be tested, thereby effectively improving the applicability of the device. Since the test device adopts an assembly method, it is not only convenient to store or transport the device, but also only the corresponding component needs to be replaced when a single component is damaged, thus facilitating the maintenance of the test device.

[0021] Before conducting the AC withstand voltage test, the extension rod 3 is pulled to slide along the inner wall of the sleeve 2, allowing the distance between the two bases 1 or the height of the mounting plate 61 to be adjusted according to the specific situation of the tool to be tested. The extension rod 3 can be limited by the locking bolt 5 and the locking hole 4. Since the first test component 6 and the second test component 7 are assembled, firstly, the corresponding test component can be selected according to the actual situation of the safety tool to be tested, thereby effectively improving the applicability of the device; secondly, it is convenient to store or transport the device; and thirdly, when a single component is damaged, only the corresponding component needs to be replaced, thus facilitating the maintenance of the test device.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: the first test component 6 includes a mounting plate 61 fixedly connected to the top of the extension rod 3. A first clamping seat 62 is sleeved on the surface of the mounting plate 61, and a second clamping seat 63 is sleeved on the surface of another mounting plate 61. A clamping plate 64 is hinged to the top of both the first clamping seat 62 and the second clamping seat 63. Limiting grooves 65 are formed on the surfaces of the first clamping seat 62, the second clamping seat 63 and the clamping plate 64. An opening and closing plate 66 is fixedly connected to one side of the first clamping seat 62, the second clamping seat 63 and the clamping plate 64. An opening and closing bolt 67 is internally threaded onto the opening and closing plate 66. A first high-voltage connector 68 is fixedly connected to one side of the first clamping seat 62, and a first grounding connector 69 is fixedly connected to one side of the second clamping seat 63. When an AC withstand voltage test is required on tools such as insulating rods, the first clamping seat 62 and the second clamping seat 63 are respectively fitted onto the surfaces of the two mounting plates 61. Then, the insulating rod is placed into the limiting groove 65. Next, the clamping plate 64 is rotated until it contacts the first clamping seat 62 or the second clamping seat 63. With the cooperation of the opening and closing bolt 67 and the opening and closing plate 66, the two ends of the insulating rod can be fixed in the first clamping seat 62 and the second clamping seat 63 respectively. Next, the output high voltage lead of the step-up device is connected to the first high voltage connector 68 and the grounding device is connected to the first grounding connector 69. Finally, the AC step-up transformer is started to perform the AC withstand voltage test on the insulating rod.

[0023] The second test assembly 7 includes a connecting plate 71 fixedly connected to one side of the base 1. A placement plate 72 is sleeved on the surface of the connecting plate 71.

A second mounting rod 75 is arranged inside the first mounting rod 74. Several leads 76 are fixedly connected to the surface of the second mounting rod 75. A second high-voltage connector 77 is fixedly connected to the top of the second mounting rod 75.

The length of the extension rod 3 extending out of the sleeve 2 can be accurately controlled by the scale 8. The fluorescent layer on its surface makes the scale 8 visible even in dim light.

[0025] The limiting grooves 65 are evenly distributed on the surfaces of the first clamping seat 62, the second clamping seat 63, and the clamping plate 64, and the limiting grooves 65 are in the shape of a "V". The limiting grooves 65 are set in the shape of a "V" so that they can fix tools such as insulating rods of different types, thereby further improving the applicability of the device.

[0026] A storage groove 9 is provided at the bottom of the connecting plate 71, and a support plate 10 is rotatably connected inside the storage groove 9.

[0027] Detailed implementation: Before conducting the AC withstand voltage test, pull the extension rod 3 so that it slides along the inner wall of the sleeve 2 fixed to the surface of the base 1.

Finally, start the AC booster transformer to perform the AC withstand voltage test on the insulating boots. When an AC withstand voltage test is required on tools such as insulating rods, place the first clamping seat 62 and the second clamping seat 63 onto the surfaces of the two mounting plates 61 fixed to the tops of different extension rods 3, and then place the insulating rods into the first clamping seat 62. The clamping plate 64 is rotated in the limiting groove 65 on the surface of the first clamping plate 62 and the second clamping plate 63 until it contacts the first clamping plate 62 or the second clamping plate 63. Then, the opening and closing bolt 67 is rotated to connect the two adjacent opening and closing plates 66, so that the two ends of the insulating rod are fixed in the first clamping plate 62 and the second clamping plate 63 respectively. Next, the high voltage output lead of the step-up device is connected to the first high voltage connector 68 fixed on one side of the first clamping plate 62, and the grounding device is connected to the first grounding connector 69 fixed on one side of the second clamping plate 63. Finally, the AC step-up transformer is started to perform AC withstand voltage test on the insulating rod, etc. The above settings can select the corresponding test components according to the actual situation of the safety tool to be tested, thereby effectively improving the applicability of the device. Since the test device adopts an assembly method, it is not only convenient to store or transport the device, but also only the corresponding component needs to be replaced when a single component is damaged, thus facilitating the maintenance of the test device.
