Technical Field

[0001] The utility model relates to the technical field of safety protection, in particular to a safety protection device for a hydraulic power tongs. Background Technique

[0002] A hydraulic tongs is a professional hydraulic tool specifically used for crimping cables and terminal lugs in electrical engineering. It has various types, including integral type, split type, electric type, and manual type, etc., which are suitable for different working requirements. The design of the hydraulic tongs enables it to crimp copper and aluminum terminal lugs and connecting pipes by means of oil pressure during the use of electric cable conductors, ensuring the quality of crimping and electrical conductivity. In addition, the hydraulic tongs also has various functions, such as rapid oil return in a rotary extrusion manner, a safety pressure relief device, a fiberglass operating insulating rod, etc., making it have wide application value in electrical engineering. In addition to its application in electrical engineering, the hydraulic tongs also plays an important role in rescue, demolition, and breaking walls and concrete floors. For example, a rescue hydraulic tongs can easily cut steel bars, open car doors or break open doors and windows, greatly improving the rescue efficiency. During the demolition process, a hydraulic crushing tongs can perform two operations of crushing concrete and cutting steel bars simultaneously, improving the work efficiency. In addition, a hydraulic breaking tongs is used for demolishing reinforced concrete structures, and has the characteristics of small volume, convenient use, no noise, and no vibration, and is suitable for construction in narrow sites.
