Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical engineering, and more specifically to a grounding device for electromechanical engineering. Background Art

[0002] Electromechanical equipment generally refers to machinery, electrical appliances and electrical automation equipment. In construction, it mostly refers to the general term for machinery and piping equipment other than geotechnical, carpentry, steel bars and mud and water equipment. It is different from hardware and mostly refers to finished products that can achieve certain functions. In order to ensure the normal operation of electromechanical equipment, a grounding device needs to be set up to achieve the purpose of connecting the electromechanical system to the earth.

[0003] Existing grounding devices, such as grounding pins, have a specification length of 50cm-70cm. When in use, they need to be driven into the ground at least 30cm to ensure the stability of the grounding connection with the ground. However, this also brings great trouble to the subsequent disassembly and replacement of the grounding pin. Since the grounding pin is embedded deep in the ground, it is very difficult to pull it out by manpower alone. Sometimes it may be necessary to dig out a certain amount of soil to pull it out. The workload is large and the disassembly and replacement process is very laborious. Therefore, the utility model provides a grounding device for electromechanical engineering. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Example

[0027] like Figure 1-4 As shown, a grounding device for electromechanical engineering includes a grounding wire 1, a grounding pin 2 and a stress-bearing base 3, one end of the grounding wire 1 is fixedly connected to the grounding pin 2, and the grounding pin 2 penetrates the stress-bearing base 3 and extends downward;

[0028] The outer circumference of the grounding pin 2 is sleeved with a collar 21, and the outer circumference of the collar 21 is threadedly connected with a fastening bolt 22, one end of the fastening bolt 22 is pressed against the outer circumference of the grounding pin 2, and the outer circumference of the collar 21 is fixedly connected with a pair of force-bearing rods 23;

[0029] A connecting block 31 is fixedly connected to the upper surface of the force-bearing base 3, and a tilting frame 32 is rotatably connected to the upper end of the connecting block 31. The tilting frame 32 contacts the force-bearing rod 23, and a connecting rod 33 is fixedly connected to the outer circumference of the tilting frame 32. A force arm rod 4 is embedded at one end of the connecting rod 33.

[0030] During use, when the grounding pin 2 needs to be disassembled, the force arm rod 4 is first embedded in the connecting rod 33, and then one end of the force arm rod 4 is pressed. At the same time, one end of the tilting frame 32 will tilt the force rod 23 upward. Since the force rod 23 cooperates with the collar 21 and the fastening bolt 22 to be placed on the grounding pin 2, when the force rod 23 tilts upward, the grounding pin 2 also tilts upward synchronously. After the tilting frame 32 drives the grounding pin 2 to tilt up a distance, the fastening bolt 22 is first loosened, and the collar 21 is moved downward. After the collar 21 drives the force rod 23 to contact the reset tilting frame 32 again, the fastening bolt 22 is then tightened. As the force arm rod 4 is pressed again, the cycle is repeated until the grounding pin 2 can be directly pulled out by personnel. The grounding pin 2 can be easily pulled out of the ground through the lever principle, which is convenient for disassembly and replacement of the grounding pin 2.

[0031] like Figure 1-2 As shown, the outer circumferential surface of the collar 21 is provided with a flat area 211 , and the flat area 211 is in full contact with one side of the fastening bolt 22 .

[0032] When in use, the flat area 1 211 can increase the contact area between the collar 21 and one side of the fastening bolt 22, thereby reducing the possibility of the fastening bolt 22 becoming loose during use.

[0033] like Figure 1-2 As shown, the outer circumferential surface of the grounding pin 2 is provided with a second flat area 24 , and the second flat area 24 is in full contact with one end of the fastening bolt 22 .

[0034] When in use, the second flat area 24 can increase the contact area between the grounding pin 2 and one end of the fastening bolt 22 , thereby increasing the friction between the fastening bolt 22 and the grounding pin 2 , thereby ensuring the stability of the collar 21 installed on the grounding pin 2 .

[0035] like Figure 4 As shown, the upper end of the grounding pin 2 is threadedly connected with a striking block 25 .

[0036] When in use, the impact block 25 is threadedly connected to the upper end of the grounding pin 2. After the impact block 25 is removed from the upper end of the grounding pin 2, the ring 21 and various accessories arranged on the outer circumference of the grounding pin 2 can be removed from the grounding pin 2. The removed ring 21 and various accessories can also be installed on a new grounding pin 2 for continued use, thereby reducing replacement costs.

[0037] like Figure 1-3 As shown, a notch 331 is formed at one end of the connecting rod 33 , and the notch 331 is engaged with one end of the lever arm 4 .

[0038] When in use, the lever arm 4 can be removed from the connecting rod 33 through the notch 331 . The lever arm 4 can be used as a disassembly tool and can be carried when the grounding pin 2 needs to be disassembled.

[0039] In summary, the specific working process of this scheme is as follows: when the grounding pin 2 needs to be disassembled, the force arm rod 4 is first embedded in the connecting rod 33, and then one end of the force arm rod 4 is pressed. At the same time, one end of the tilting frame 32 will tilt the force rod 23 upward. Since the force rod 23 cooperates with the collar 21 and the fastening bolt 22 to be placed on the grounding pin 2, when the force rod 23 tilts upward, the grounding pin 2 also tilts upward synchronously. After the tilting frame 32 drives the grounding pin 2 to tilt up a distance, the fastening bolt 22 is first loosened, and the collar 21 is moved downward. After the collar 21 drives the force rod 23 to contact the reset tilting frame 32 again, the fastening bolt 22 is then tightened. As the force arm rod 4 is pressed again, the cycle is repeated until the grounding pin 2 can be directly pulled out by personnel. The grounding pin 2 can be easily pulled out of the ground through the lever principle, which is convenient for disassembly and replacement of the grounding pin 2.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
