Description

Technical Field

[0001] This utility model belongs to the field of insulating glove testing, and in particular relates to an insulating glove airtightness insulation testing device. Background Technology

[0002] The airtightness and insulation test of insulating gloves is a crucial step in ensuring their safe use. This mainly includes an air-filling test and an insulation test. The air-filling test involves filling or blowing air into the insulating gloves to check for leaks. The insulation test typically uses a water immersion method. At a temperature of 21-25°C, the insulating gloves are filled with water and immersed in a tank. An AC voltage is applied until the specified test voltage is reached or a flashover occurs. The applied voltage should be maintained for at least one minute.

[0003] Comparing with Chinese Patent No. CN206804233U, a device for testing the airtightness and insulation of insulating gloves and boots is disclosed. It includes a platform with casters on its underside, a water tank, a withstand voltage tester, and an air pump on its upper side. A column is located in the middle of the upper side of the platform, with a fixing ring connected to its upper end. A horizontal rod is connected to one side of the fixing ring, and a clamp is attached to the end of the horizontal rod. An insulator is connected to the lower side of the clamp. An insulating glove / boot plug is located below the insulator. A copper rod, an air check valve, and a water valve are arranged through the middle of the insulating glove / boot plug. The upper end of the copper rod is connected to the insulator. A fixing ring is located on the outer side of the insulating glove / boot plug. This device is easy to operate, allows for simultaneous airtightness and withstand voltage testing, is portable and easy to transport, simple to use, and inexpensive.

[0004] However, the aforementioned patent requires that one insulating glove must be tested before the next insulating glove can be installed or removed, which prolongs the auxiliary time for installation and removal and seriously slows down the testing speed. Therefore, a new device needs to be designed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 An airtightness and insulation testing device for insulating gloves includes an execution component for testing the airtightness and insulation of insulating gloves, and a frame assembly for alternating dual-station testing. Two tooling components for fixing insulating gloves for airtightness and insulation testing are symmetrically mounted on the frame assembly. Two execution components are symmetrically arranged and are independently connected to the two tooling components respectively.

[0026] In this embodiment: the frame assembly includes a workbench 101, on which water tank cylinders 102 are symmetrically mounted. A drive mechanism for alternating lifting and lowering is provided behind the workbench 101. The drive mechanism includes a support frame 103, on which two limiting grooves 104 are symmetrically arranged on both sides. A rack 105 is slidably mounted in the limiting grooves 104. A support frame 106 is provided on the outside of the rack 105. A gear 108 meshes between the two racks 105. A servo motor 107 is provided in front of the gear 108. The racks 105 pass through the workbench 101. The support frame 103 and the workbench 101 are bolted together. Two water tank cylinders 102 filled with clean water are inserted into the workbench 101. The support frame 103 supports the servo motor 107 to drive the gear 108 to rotate. At the same time, the gears 105 on both sides mesh, pushing the racks 105 on both sides to move one downward and the other upward along the limiting grooves 104. The support frame 106 drives the lifting frames 201 on both sides to move in the opposite direction.

[0027] In this embodiment: the tooling assembly includes a lifting frame 201, an insulator 202 is installed at the front end of the lifting frame 201, and a clamping mechanism is installed below the insulator 202; the clamping mechanism includes a fixed frame 204, a fixing ring 205 is installed around the circumference of the fixed frame 204, and a connecting seat 203 is provided at the top of the fixed frame 204; a bidirectional air pipe 303 and a copper rod 304 pass through the fixed frame 204 from the top; the insulating glove is put on one side of the fixed frame 204 and pressed and fixed with the fixing ring 205; the lifting frame 201 pushes the insulator 202 down, so that the connecting seat 203 drives the insulating glove to move up and down through the fixed frame 204;

[0028] In this embodiment: the execution components include a gas charging / discharging mechanism for airtightness testing and a gas charging / discharging mechanism for insulation testing; the gas charging / discharging mechanism includes a bidirectional air pump 302, a bidirectional air pipe 303 is disposed above the bidirectional air pump 302, and a flexible hose is used to connect the bidirectional air pump 302 and the bidirectional air pipe 303; the gas charging / discharging mechanism includes a withstand voltage tester 301, a copper rod 304 is disposed above the withstand voltage tester 301, and an electrical connection is used between the withstand voltage tester 301 and the copper rod 304; the bidirectional air pump 302 inflates the insulating glove through the bidirectional air pipe 303 to check its airtightness, and then the bidirectional air pump 302 extracts air from the insulating glove through the bidirectional air pipe 303 to cause it to contract and press tightly against the copper rod 304, so that the withstand voltage tester 301 tests its insulation through the copper rod 304.

[0029] Working principle: First, insert two water tanks 102 filled with clean water onto the workbench 101. Then, put the insulating gloves under the fixing bracket 204 on one side and tighten them with the fixing ring 205. Then, the support frame 103 supports the servo motor 107 to drive the gear 108 to rotate, which in turn meshes with the racks 105 on both sides, pushing the racks 105 on both sides to move one downward and the other upward along the limiting slide groove 104. The rack 105 on the downward side drives the lifting frame 201 through the support frame 106 to push the insulator 202 downward, so that the connecting seat 203 immerses the insulating gloves in the clean water in the water tank 102 through the fixing frame 204. The other side of the fixed frame 204 rises to facilitate the installation of the second insulating glove. After the insulating glove is immersed in clean water, the bidirectional air pump 302 on the same side inflates the insulating glove through the bidirectional air pipe 303 to check its airtightness. Then, the bidirectional air pump 302 extracts air from the insulating glove through the bidirectional air pipe 303 to make it contract and fit tightly against the copper rod 304, so that the withstand voltage tester 301 tests its insulation through the copper rod 304. After completion, the servo motor 107 reverses, and the lifting state of both sides reverses to test the second insulating glove. The first insulating glove is then removed, and the third insulating glove is installed. This cycle is repeated to test alternately.
