The invention provides a pipe clamping device, and belongs to the technical field of cast pipe hoisting. The pipe clamping device comprises a hanging bracket, a plurality of connecting blocks, a driving rod, a plurality of driving wheels and a chain, wherein the plurality of connecting blocks correspond to a plurality of clamp arms one to one, and the connecting blocks are hinged to the corresponding clamp arms; first spiral teeth and second spiral teeth are arranged at the two ends of the driving rod, and the rotating directions of the first spiral teeth and the second spiral teeth are opposite; the first spiral teeth and the second spiral teeth are in spiral fit with the two opposite connecting blocks, and the driving rod is in transmission connection with a driving piece and used for driving the two clamp arms to move; the plurality of driving wheels are arranged at the ends of the plurality of clamp arms and used for supporting cast pipes in a matched mode; and the chain is in transmission connection with power pieces and the driving wheels on the two opposite clamp arms, and drives the cast pipes to rotate through the plurality of driving wheels. According to the pipe clamping device, the cast pipes rotate in the hoisting process by means of the driving piece and the chain, and the whole structure is safe and reliable and convenient to install and maintain.
Description
technical field [0001] The invention belongs to the technical field of cast pipe hoisting, and more specifically relates to a pipe clamping device. Background technique [0002] The hot cast pipe needs to be hoisted to the cooling bed by a crane before it is put into storage. Due to the high temperature of the hot-cast pipe itself during the initial molding, the corresponding structural strength is relatively low, and the quality of the cast pipe itself is relatively large, so rollers are installed at the bottom of the sling, and the rollers drive the cast pipe during the hoisting process. turn. But in order to realize the above-mentioned functions, the structure of the existing cast pipe hoisting and clamping device is all relatively complicated, which brings a lot of inconvenience to installation and maintenance. Contents of the invention [0003] The object of the present invention is to provide a clamping device, aiming to solve the problem that the structure is rela...
