Description

Clamping type pipeline welding fireproof device Technical Field The utility model belongs to the technical field of auxiliary tools of welding machines, and relates to a clamping type pipeline welding fireproof device. Background In many work scenarios involving high-rise welded pipes, such as urban heating pipe laying, petrochemical pipe installation and repair, sparks generated during welding inevitably fall from high-rise. These scattered sparks, once they contact surrounding inflammables, such as insulation materials, protective canvases or other inflammable devices, are extremely prone to fire accidents. At present, means for spark protection is relatively limited when a pipeline is welded at a high place, and the traditional protection measures are difficult to comprehensively and effectively prevent sparks from splashing everywhere, so that fire hazards exist. Disclosure of utility model Aiming at the problems, the utility model provides a clamping type pipeline welding fireproof device which well solves the problems in the prior art. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a clasping type pipe welding fire protection device comprising: the upper clamp comprises a plurality of arc hoops which are fixedly connected in sequence; The lower clamp is of an upper clamp mirror image structure, and one end of the lower clamp is hinged with the upper clamp; the fixing bolt comprises a screw and a nut, a connecting hole is formed in one end, far away from the hinged end, of the upper clamp and the lower clamp, and the nut is a butterfly nut; the connecting rod is arranged at the hinge end of the lower clamp; The annular ring is rotatably arranged at one end, far away from the lower clamp, of the connecting rod; the opening end of the fireproof cloth bag is fixedly arranged on the annular ring. Optionally, the connecting rod can install in the ground embracing card in a sliding way, the connecting rod is installed the mounting, is used for fixing the connecting rod position. Optionally, the fixing member includes: The tooth grooves are formed in the side face of the connecting rod in a linear array along the axial direction of the connecting rod; the mounting ring is fixedly arranged on the lower holding clamp, and is sleeved on the outer side of the connecting rod; The fixing pin is slidably arranged on the side face of the mounting ring and penetrates through the mounting ring to prop against the tooth grooves. Optionally, a positioning spring is fixedly installed between the fixing pin and the mounting ring, and both sides of the tooth slot and the fixing pin, which are positioned in the axial direction of the connecting rod, are inclined planes.
