Abstract

The invention discloses a dead-weight pressing furnace door adopting rollers. The dead-weight pressing furnace door comprises a trolley, two hydraulic cylinders, a trolley door post, an outer-layer sliding portal frame, an inner-layer sliding portal frame, chain wheels and a roller chain, wherein one end of the each hydraulic cylinder is connected to the trolley door post through a hinged shaft; the top end of the piston rod of each hydraulic cylinder is connected to the outer-layer sliding portal frame; and four chain wheels are mounted in a beam of the outer-layer sliding portal frame. The dead-weight pressing furnace door adopting rollers is characterized in that piston rods of the two hydraulic cylinders extend out to drive the four chain wheels to upwards move along a rail in the trolley door post, so that the inner-layer sliding portal frame moves along the inner side rollers of the outer-layer sliding portal frame at twice the speed of the outer-layer sliding portal frame. According to the dead-weight pressing furnace door adopting rollers, an inclined rail is arranged on the rail, the dead-weight pressing furnace door is formed by the rollers and the inclined rail, and the sealing effect during dead-weight pressing of the furnace door can be adjusted. The dead-weight pressing furnace door adopting rollers is novel in conception, is reasonable in design, is safe and reliable; the parts are simple to configure, are durable in use, are not liable to damage, are simple and time-saving to mount; and the use time of the furnace door is greatly prolonged due to a movable adjusting function, and the secondary maintenance is very convenient.

Description

technical field [0001] The invention relates to the technical field of industrial heat treatment furnaces, in particular to a self-weight pressing furnace door. technical background [0002] In the form of industrial metal heat treatment furnace door, the existing technology mostly uses lever to compress the furnace door, or fixed self-pressing furnace door, its disadvantages and shortcomings: easy to damage, especially after the furnace door sealing material is worn, the furnace door cannot be sealed The adjustment of pressure cannot be used repeatedly, and the workload of repairing is heavy. Contents of the invention [0003] In view of the deficiencies in the above industrial heat treatment furnaces, the purpose of the present invention is to provide a roller self-weight pressing furnace door, which adopts an adjustable roller and track structure to realize the sealing effect of the adjustable furnace door self-weight pressing. [0004] The present invention is solved ...
