Problems solved by technology

In the past, the furnace door lifting equipment was mainly driven by motors and coupling transmissions. One side was connected to the furnace door, and the other side was hung with a counterweight, and the counterweight was exposed outside the device. In this way, a safety guardrail must be installed at the bottom of the counterweight. and costly

Abstract

The invention belongs to the technical field of heating furnaces and more particularly relates to a device for opening and closing a furnace door of a heating furnace, in particular to a furnace door lifting device with counterweights. The furnace door lifting device comprises an electromotor, a first short link chain, a second short link chain, a third short link chain, a forth short link chain, a fifth short link chain, a double-row driving chain wheel group, a single-row driven chain wheel group, first counterweights, a second counterweight and a furnace door frame; the counterweight is suspended at one end of the first short link chain and one end of the second short link chain, and the first counterweight is positioned in a first furnace door upright internal cavity of a first furnace upright; the other end of the first short link chain bypasses a first chain wheel and a third chain wheel in sequence and is connected to a second hanging point on the furnace door, and the other end of the second short link chain bypasses the second chain wheel and is connected to a first hanging point on the furnace door; the second counterweight is suspended at one end of the third short link chain, and the second counterweight is positioned inside a second furnace door upright internal cavity of a second furnace door upright. The furnace door lifting device disclosed by the invention has the characteristics of safety, stability and good economic efficiency.

Description

[0001] technical field [0002] The invention belongs to the technical field of heating furnaces, in particular to a device for opening and closing a furnace door of a heating furnace, in particular to a furnace door lifting device with a counterweight. Background technique [0003] Most of the industrial furnace doors are opened and closed up and down. The furnace door rises and falls along the vertical furnace mouth guide plate, and the furnace door has a furnace door lifting mechanism with a special pressing device. Commonly used furnace door lifting devices are divided into manual, electric and pneumatic. Furnace door lifting devices are generally used in industrial furnaces that heat metal. The lifting power is determined according to the appropriate size and size of the furnace door. The temperature is high and the operation is frequent. The furnace door lifting device is required to have high strength, rigidity and heat resistance. Ability to creep deformation. In t...
