Abstract

The invention discloses a quick welding connector for field rescue, and belongs to the technical field of structural connection. The quick welding connector comprises a bottom plate and a lifting ring connected above the center of the bottom plate; the upper surface of the bottom plate is uniformly and fully paved with explosives; positioning devices are arranged at four corners of the bottom plate; and the positioning devices are connected with a rescued object. According to the device, under the conditions that hoisting is needed in the field and no appropriate tool or electricity / gas source exists, under the condition that the lifting ring connector needs to be rapidly connected for hoisting, the acting points are rapidly increased through the device, and rescue work is carried out.

Description

technical field [0001] The invention belongs to the technical field of structural connection, and in particular relates to a quick welding joint for field rescue. Background technique [0002] When encountering sudden natural disasters such as earthquakes and shipwrecks, it is often necessary to carry out emergency rescue and salvage work. In the process of field rescue, sometimes it is necessary to carry out towing or lifting operations, and it is necessary to find a suitable focus on large structures to carry out emergency work; When rescue, salvage and other work require rescue tools such as cranes to operate, there is often no suitable focus, which greatly increases the difficulty of rescue and salvage work. Oftentimes, finding a suitable anchor point is difficult and requires the installation of joints or hitch points on the object being towed (lifted). The conventional method of installing joints or hanging points is mechanical connection or welding, which requires el...
