A support frame for wrapping a frame at the end of a ventilation duct

Abstract

The invention relates to a supporting frame for end frame wrapping of ventilation pipelines. The supporting frame comprises a bottom plate, a cylindrical frame body is arranged on the bottom plate, and a plurality of guide columns evenly penetrate the frame body. Spherical faces are arranged at the inner ends of the guide columns, the portions, inside the frame body, of the guide columns are sleeved with limiting rings, and compression springs arranged on the corresponding guide columns in a sleeving manner are arranged between the limiting rings and the frame body. Arc-shaped push plates located outside the frame body are fixed to the outer ends of the guide columns, and a plurality of through holes are evenly formed in the push plates. A cam is arranged in the middle of the frame body, and a rotary shaft is fixed to the upper end face of the cam. A section of spline is arranged in the middle of the rotary shaft, a fixed sleeved fixed to the upper portion of the frame body is arranged on the spline in a matching manner, and a rotary flange is arranged at the upper end of the rotary shaft. The guide columns are pushed by the disc-shaped cam to stretch outwards at the same time, the arc-shaped push plates are pushed outwards, and the interior of the frame body can be supported by the push plates. According to different push-out distances of the push plates, the ventilation pipelines with different diameters are supported, and equipment adaptability is improved.

Description

technical field [0001] The invention relates to the technical field of marine ventilation pipe processing equipment, in particular to a support frame for wrapping a frame at the end of a ventilation pipe. Background technique [0002] In order to ensure the ventilation of the space inside the hull, ventilation ducts are installed inside the hull. At present, the ventilation ducts are often made of alloy iron sheets with high corrosion resistance. Assembly needs, usually riveted angle steel at the end of the ventilation duct made of alloy iron sheet. [0003] The end of the iron sheet is sharp, and it is dangerous to manually wrap and install the angle steel, and workers are often injured. Therefore, people need a device that can assist in manually fixing the angle steel to the end of the alloy iron sheet, so that the assembler can rivet the two. [0004] When the angle steel reinforcement is carried out at the end of the cylindrical ventilation duct, people need a fixed sup...
