Technical Field

[0001] This utility model belongs to the field of grounding resistance detection technology, specifically relating to a portable grounding resistance testing device. Background Technology

[0002] A grounding resistance meter, also known as a grounding resistance tester, is an instrument specifically designed to directly measure the grounding resistance of various grounding devices. It is a resistance measuring device used in power, telecommunications, railway, communications, and mining sectors to measure the grounding resistance of various devices and the resistance of low-resistance conductors. It can also measure soil resistivity and ground voltage.

[0003] Existing ground resistance testing equipment is prone to displacement due to external factors during the testing process, especially portable ground resistance testing equipment, which affects its stability during the measurement process and thus affects the test data. Therefore, it is necessary to design a portable ground resistance testing device with good stability. Utility Model Content

[0004] The purpose of this invention is to provide a portable grounding resistance testing device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable grounding resistance testing device includes a support frame assembly, a slide assembly slidably connected to the inner wall of the support frame assembly, a grounding resistance tester fixedly connected to the top of the slide assembly, a lifting motor fixedly connected to the outer wall of the support frame assembly, a winding shaft fixedly connected to the output shaft of the lifting motor via a coupling, and a pull rope fixedly connected to the outer wall of the winding shaft.

[0007] The slide assembly includes a sliding plate slidably mounted on the inner wall of the support frame assembly, with a locking mechanism at the top of the sliding plate. Through the slide assembly, during use, when the testing device moves to the testing position via the support frame assembly, the support frame assembly is fixed to the ground. Then, the lifting motor is started and controlled to rotate the winding shaft, allowing the slide assembly to slide down the inner wall of the corner frame to the position of the grounding resistance tester. The testing terminal of the grounding resistance tester is then removed and connected to the resistor or soil to be tested. The rotary motor is then started and controlled to rotate the positioning plate, causing the outer wall of the positioning plate to fit tightly against the corner frame via rubber blocks. This maintains a fixed connection between the slide assembly and the support frame assembly, effectively preventing the slide assembly from sliding on the inner wall of the support frame assembly due to external forces, which could affect the connection of the testing terminal of the grounding resistance tester. This improves the stability of the device during testing and helps to improve the accuracy of the test results.

[0008] The locking mechanism includes a rotary motor fixedly mounted on the slide plate, the output shaft of the rotary motor being fixedly connected to a positioning plate via a coupling, and a rubber block being fixedly connected to the inner wall of the positioning plate;

[0009] The support frame assembly includes a corner frame mechanism, and the outer wall of the corner frame mechanism is provided with a positioning mechanism. With the support frame assembly, in use, firstly, the lifting hydraulic cylinder is started and controlled to lift and increase the relative distance between the corner frame and the rollers, so that the rollers contact the ground, so as to move the position of the testing device, improve its flexibility, and thus achieve the purpose of portable use.

[0010] Then, after the device is moved to the usage position, the lifting hydraulic cylinder is activated and controlled to lift and reduce the relative distance between the corner frame and the rollers, so that it retracts into the corner frame. Then, the device is fixed to the ground by bolts and other positioning rod mechanisms in conjunction with fixing holes, thereby improving the overall stability of the device.

[0011] The corner frame mechanism includes a corner frame, a fixed pulley is movably connected to the upper inner wall of the corner frame, a motor base is fixedly connected to the outer wall of the corner frame, and a fixing hole is opened on the bottom outer wall of the corner frame;

[0012] The positioning mechanism includes a side frame fixedly installed on the outer wall of the corner frame, a lifting hydraulic cylinder fixedly connected to the bottom of the side frame, and rollers movably connected to the bottom of the lifting hydraulic cylinder.

[0013] As a preferred embodiment of this utility model, the top of the slide plate is provided with a through groove, and the number of through grooves is multiple; by setting multiple through grooves, not only is it better to dissipate heat from the bottom of the grounding resistance tester, but it also reduces the weight of the slide plate itself, thereby facilitating lifting and lowering operations in conjunction with the lifting motor.

[0014] As a preferred embodiment of this utility model, the positioning plate is a "7"-shaped positioning plate, and the inner wall of the positioning plate is connected to the outer wall of the corner frame by rubber blocks.

[0015] As a preferred embodiment of this utility model, the bottom of the corner frame is provided with a bottom groove, and the rollers are disposed on the inner wall of the bottom groove.

[0016] As a preferred embodiment of this utility model, the number of positioning mechanisms is multiple, and the multiple positioning mechanisms are respectively arranged at the four corners of the skateboard.

[0017] In a preferred embodiment of this utility model, the outer wall of the pull rope is fitted and connected to the inner wall of the fixed pulley, and one end of the pull rope is fixedly connected to the outer wall of the slide plate.

[0018] As a preferred embodiment of this utility model, the top of the side frame is fixedly connected to two triangular ribs, and the outer walls of the two triangular ribs are fixedly connected to the outer wall of the corner frame.

[0019] In a preferred embodiment of this utility model, there are multiple support frame assemblies, and adjacent support frame assemblies are arranged symmetrically to each other, and the multiple support frame assemblies are fixedly connected by fixing rods.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up the slide assembly, when the testing device moves to the position to be tested via the support frame assembly, the support frame assembly is fixed on the ground. Then, the lifting motor is started and controlled to drive the winding shaft to rotate and retract the rope, so that the slide assembly slides down along the inner wall of the corner frame to the position of the grounding resistance tester. Then, the testing end of the grounding resistance tester is taken out and connected to the resistance to be tested or the soil for testing. The rotary control motor is started and controlled to drive the positioning plate to rotate, so that the outer wall of the positioning plate is tightly attached to the corner frame by the rubber block, so that the slide assembly and the support frame assembly are fixedly connected. This effectively avoids the slide assembly from sliding on the inner wall of the support frame assembly due to external force, which would affect the connection effect of the testing end of the grounding resistance tester. This improves the stability of the device during testing and helps to improve the accuracy of the test results.

[0021] By setting up the support frame assembly, during use, firstly, the lifting hydraulic cylinder is started and controlled to lift and lower, increasing the relative distance between the corner frame and the rollers, so that the rollers contact the ground, so as to move the position of the testing device, improve its flexibility, and thus achieve the purpose of portable use;

[0022] Then, once the device is moved to the desired position, the lifting hydraulic cylinder is activated and controlled to lift and lower the relative distance between the corner frame and the rollers, causing it to retract into the corner frame. Then, the device is fixed to the ground using bolts and other positioning rod mechanisms in conjunction with fixing holes, thereby improving the overall stability of the device.

[0036] The slide assembly 2 includes a slide plate 201 slidably disposed on the inner wall of the support frame assembly 3, with a locking mechanism 202 at the top of the slide plate 201. Through the slide assembly 2, during use, when the testing device moves to the position to be tested via the support frame assembly 3, the support frame assembly 3 is fixed to the ground. Then, the lifting motor 4 is started and controlled to drive the winding shaft to rotate and retract the pull rope 5, causing the slide assembly 2 to slide down along the inner wall of the corner frame 3011 to the position of the grounding resistance tester 1. Then, the testing end of the grounding resistance tester 1 is removed and connected to... After the resistance tester or soil connection is completed, the test is performed. The rotary motor 2021 is started and controlled to drive the positioning plate 2022 to rotate. This causes the outer wall of the positioning plate 2022 to be tightly attached to the corner frame 3011 by the rubber block 2023. This keeps the slide assembly 2 and the support frame assembly 3 in a fixed connection, effectively preventing the slide assembly 2 from sliding on the inner wall of the support frame assembly 3 due to external force, which would affect the connection effect of the detection end of the grounding resistance tester 1. This improves the stability of the device during testing and helps to improve the accuracy of the test results.

[0038] Preferably, the top of the slide plate 201 is provided with a through groove 203, and the number of through grooves 203 is multiple;

[0039] It should be noted that the positioning plate 2022 is a "7" shaped positioning plate, and the inner wall of the positioning plate 2022 is attached to the outer wall of the corner bracket 3011 through the rubber block 2023;

[0040] In use: When the testing device is moved to the position to be tested via the support frame assembly 3, the support frame assembly 3 is fixed on the ground. Then, the lifting motor 4 is started and controlled to drive the winding shaft to rotate and retract the rope 5, so that the slide assembly 2 slides down the inner wall of the corner frame 3011 to the position of the grounding resistance tester 1. Then, the testing end on the grounding resistance tester 1 is taken out and connected to the resistance to be tested or the soil for testing.

[0041] In summary: By setting up the slide assembly 2 and controlling the lifting motor 4, the usage positions of the slide assembly 2 and the grounding resistance tester 1 can be adjusted. Then, by controlling the rotary motor 2021, the positioning plate 2022 is rotated, so that the outer wall of the positioning plate 2022 is tightly attached to the corner frame 3011 through the rubber block 2023. This ensures that the slide assembly 2 and the support frame assembly 3 are fixedly connected, effectively preventing the slide assembly 2 from sliding on the inner wall of the support frame assembly 3 due to external force, which would affect the connection effect of the detection end of the grounding resistance tester 1. This improves the stability of the device during testing and helps to improve the accuracy of the test results.

[0042] By setting multiple through slots 203, not only is heat dissipation at the bottom of the grounding resistance tester 1 improved, but the weight of the slide plate 201 itself is also reduced, so as to facilitate lifting and lowering operations in conjunction with the lifting motor 4.
