Abstract

This invention relates to a cure furnace door device of tubing inner-coat including a door, frame upright posts set at both sides of the door, a frame beam on top of the two posts, an extension end set at one end of the beam with two driven wheels on it, a driving double-chain wheel on the extending end of the beam with a hung balance heavy at the bottom, two door lifting chains connected to the top of the heavy and connected to the top of the door via the two driving double chain wheels and two driven chain wheels to form a balanced electric lifting mode and two sets of cylinders for sealing the door pneumatically on the upright posts at both sides of the door, which increases safety and reliability of the door and utilizes a cylinder to push the door to seal it quickly.

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...
