Description

Technical Field

[0001] The utility model belongs to the technical field of substation construction in the electric power industry, and particularly relates to an additional module for a quick-pressing self-locking wrench. Background Art

[0002] In the construction of substations in the power industry, the extension of the power construction wrench head is a measure to increase the lever arm, amplify the torque and detect torque and other additional modules. The torque wrench or lever can be added to the added head to change the performance and method of the wrench, and the torque detection device can be added to perform torque detection. It is manufactured after a long period of research and development based on ergonomics theory. It is currently widely used in the field of power equipment installation and maintenance. The torque wrench is a tool for measuring and controlling torque, which can control the torque of rotating mechanical parts. The working principle of the power construction torque wrench is to use the spring on the blade spring to form a torque on the wrench head, so that the nut or bolt produces the desired tightening force. The torque measured on the wrench head is indicated by the pointer on the wrench, ensuring the accuracy, uniformity and reliability of the tightening force, ensuring the safety of the tower and electrical equipment, and playing a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment.

[0003] Anchor bolts are bolts used to fix the foundation of a building. They are usually used to transfer the weight of the building to the soil through the foundation to ensure the stability and safety of the building. In substations, anchor bolts also have the function of stabilizing and fixing buildings. Substation equipment is generally large, including transformers, switchgear, cables, etc. These equipment need to be attached to the foundation through brackets, bracket grounding devices, etc. Anchor bolts are bolts used to fix brackets, bracket grounding devices and other equipment to the foundation. Anchor bolts are crucial in substations. They can not only ensure the stability and safety of equipment, but also improve the grounding effect and effectively protect the stable operation of substation facilities and power systems. Therefore, in the construction and maintenance of substations, the torque of anchor bolts needs to be carefully and accurately measured to ensure that they play an effective and stable role. Using a torque wrench to tighten the bolts can improve the construction accuracy and construction quality of the tightening bolts and improve the overall construction level.
