Abstract

A furnace door device for curing the inner coating of pipes, which includes a furnace door, frame columns are arranged on both sides of the furnace door, a frame beam is arranged on the upper ends of the two frame columns, and a protruding end is provided at one end of the frame beam , there are two driven sprockets on the frame beam, a driving double sprocket is set on the protruding end of the frame beam, and a balance hoisting object is arranged at the lower part of the protruding end, and the upper end of the balance hoisting object is connected with Two furnace door lifting chains, the two furnace door lifting chains are connected to the upper end of the furnace door after passing through the active double sprocket and respectively passing through two driven sprockets to form a balanced electric lifting method; frame columns on both sides of the furnace door There are two sets of cylinders for pneumatically sealing the furnace door. The beneficial effects of the present invention are: adopting the balanced electric lifting method to improve the safety and reliability of the furnace door; using the cylinder to push the furnace door to achieve the purpose of fast sealing, which can save time and improve work efficiency. It can fully meet the process requirements of the curing furnace.

Description

technical field [0001] The invention relates to the technical field of curing furnaces, and relates to a furnace door device for a pipe inner coating curing furnace. Background technique [0002] At present, oil pipes and drill pipes used in oil fields can greatly prolong their service life after being coated with a high-temperature-cured non-metallic coating on the inner wall. In the high-temperature curing process, a curing furnace with a larger furnace volume and a larger furnace mouth must be used. The furnace door of the large-volume closed heating furnace currently used generally adopts the structure of electric lifting and top bar sealing. Its security is lower, and work efficiency is lower. Contents of the invention [0003] The object of the present invention is to provide a safe, reliable and high-efficiency balanced electric lifting and pneumatic sealing furnace door device. [0004] To achieve the above object, the present invention takes the following techn...
