DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See also Figure 1-3 As shown, the utility model is a test tank mother and child cart for withstand voltage test, including a mother cart 1 for carrying, the mother cart 1 is in an L shape, and two parallel slide rails 5 are arranged in the horizontal direction of the mother cart 1, and the cross section of the slide rail 5 is in an inverted "V" shape. A sub-carriage 4 is arranged above the slide rail 5, and a plurality of concave wheels 6 corresponding to the slide rail 5 are rotatably arranged on both sides of the bottom of the sub-carriage 4, and the distance between the concave wheels 6 on both sides is adapted to the distance between the tracks 13 on both sides of the test tank 12, and the concave wheels 6 are movably arranged on the slide rail 5. There are multiple pulling devices 3 for pulling samples on both sides of the sub-carriage 4, and clamping devices 2 for clamping samples are also provided on both sides above the sub-carriage 4. A blocking rod 14 is provided at the bottom of the sub-carriage 4, and the blocking rod 14 extends to the bottom of the mother car 1. When the sub-carriage 4 is pushed out, the blocking rod 14 plays a role of limiting, effectively preventing the sub-carriage 4 from sliding off the mother car 1. When in use, the sample to be tested is first placed on the sub-carriage 4 by a crane. If there is a structure that can be hooked and stabilized around the sample, multiple hooks 33 are used to hang the sample from different directions, and the sample is elastically fixed. Under the action of the rope 32, the sample is pulled to effectively prevent the sample from falling during transportation. If there is no structure around the sample that can be hooked and stabilized, the sample is placed between the clamping devices 2 on both sides, and the screws 22 on both sides are rotated by the handles 24, so that the rubber pressing blocks 23 on both sides clamp the sample, thereby preventing it from falling. After the sample is fixed, the sample is transported to the entrance and exit of the test tank 12 by the mother car 1, and the mother car 1 is fixed by the braking function of the universal wheel 9, and then the child car 4 is pushed. The recessed wheels 6 under the child car 4 walk along the track 13 in the test tank, which plays a supporting and guiding role, so that the child car 4 can smoothly enter the test tank 12 with the sample. When it reaches a specific area, the clamping device and the pulling device 3 are released, and then the sample is moved to the test platform in the test tank 12, thereby completing the loading work. The use of this device can quickly place the sample at a specific position in the test tank 12, effectively improving work efficiency, and no lifting is required, effectively reducing the labor intensity of employees.

[0022] Specifically, the pulling device 3 includes a connecting block 31, an elastic rope 32 and a hook 33. The connecting block 31 is installed on one side above the sub-trolley 4. One end of the elastic rope 32 is connected to the connecting block 31, and the other end of the elastic rope 32 is connected to the hook 33. By hanging the sample from different directions with multiple hooks 33, the sample is pulled under the action of the elastic rope 32, which effectively prevents the sample from falling during transportation.

[0023] Preferably, a plurality of pulling devices 3 are arranged in a rectangular shape on the two side edges above the sub-trolley 4 , and there are four pulling devices 3 , which pull from different directions, so that the sample is more stable on the sub-trolley 4 .

[0024] Furthermore, the clamping device 2 includes a column 21, a screw 22 and a rubber clamping block 23. The column 21 is arranged on one side above the sub-trolley 4. The screw 22 is threadedly connected to the column 21. The rubber clamping block 23 is rotatably connected to one end of the screw 22 on the inner side of the column 21. A handle 24 is provided at the other end of the screw 22. The sample is placed between the clamping devices 2 on both sides. The screws 22 on both sides are rotated by the handle 24, so that the rubber clamping blocks 23 on both sides clamp the sample, thereby preventing it from falling.

[0025] Furthermore, both the mother vehicle 1 and the sub-vehicle 4 are frame structures, and both the mother vehicle 1 and the sub-vehicle 4 are made of square steel, which has a simple structure and a low manufacturing cost, and is conducive to promotion.

[0026] Furthermore, a buffer cotton 7 is sleeved on the cross bar at the upper end of the mother trolley 1, and the child trolley 4 is in contact with the buffer cotton 7. When the child trolley 4 is retracted, the buffer cotton 7 plays a buffering role to protect the child trolley 4. At the same time, the buffer cotton 7 plays a barrier role to prevent the child trolley 4 from pinching the operator's hands when pushing and pulling the mother trolley 1.

[0027] Furthermore, an anti-skid plate 11 is provided on the top of the sub-trolley 4. The anti-skid plate 11 is made of silicone material and has an anti-slip effect. Since silicone has a certain elasticity, it also has a buffering effect on the sample, effectively protecting the sample from bumps during transportation.

[0028] Furthermore, a plurality of universal wheels 9 with a braking function are provided at the bottom of the mother vehicle 1, and the universal wheels 9 are connected to the mother vehicle 1 through a telescopic rod 8, and a locking screw 10 is threadedly connected to the telescopic rod 8. By adjusting the length of the telescopic rod 8, the height of the entire vehicle can be adjusted, so that the sub-vehicle 4 can meet the use of test tanks 12 of different heights, thereby increasing its scope of application.

[0029] When using a test tank trolley for a withstand voltage test of this embodiment, the sample to be tested is first placed on the trolley 4 by a crane. If there is a structure that can be hooked and stabilized around the sample, multiple hooks 33 are used to hang the sample from different directions. Under the action of the elastic rope 32, the sample is pulled to effectively prevent the sample from falling during transportation. If there is no structure that can be hooked and stabilized around the sample, the sample is placed between the clamping devices 2 on both sides, and the screws 22 on both sides are rotated by the handles 24, so that the rubber pressing blocks 23 on both sides press the sample. The sample is clamped to prevent it from falling. After the sample is fixed, the sample is transported to the entrance and exit of the test tank 12 by the mother car 1. The mother car 1 is fixed by the brake function of the universal wheel 9, and then the child car 4 is pushed. The recessed wheel 6 under the child car 4 moves along the track 13 in the test tank to play a supporting and guiding role, so that the child car 4 can smoothly enter the test tank 12 with the sample. When it reaches a specific area, the clamping device and the pulling device 3 are released, and then the sample is moved to the test platform in the test tank 12 to complete the loading work. The utility model is a test tank mother and child cart for withstand voltage test, which can quickly and accurately place the test sample to the specified position, effectively improve work efficiency, increase operational safety, and has the characteristics of easy use and strong practicality.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
