Embodiment Construction

[0020] The present invention will be described in further detail below in combination with specific embodiments.

[0021] Such as figure 1 , figure 2 and image 3 The shown manual return device for the steel tapping machine includes a transmission device and a motor 2 for the steel tapping machine. The transmission shaft wraps the gate 1, and the motor 2 drives the steel arm of the steel loading machine or tapping machine to move through the transmission device. It also includes a jaw clutch 3 arranged at the non-output end of the motor 2, the other end of the jaw clutch 3 is connected with the clutch transmission, and the clutch transmission is a sprocket transmission structure, including a driving sprocket 10, a driven sprocket 12 and chain 9, wherein driven sprocket 12 is coaxially connected with jaw clutch 3, and driving sprocket 10 is connected with hand wheel 5.

[0022] In this embodiment, the jaw clutch 3 is divided into two parts, the active half clutch and the p...

Abstract

The invention provides a conveniently operated manual retreat device of a charge / discharge machine, and with the device, steel charge arms or steel discharge arms can be retreated out of a heating furnace by manual operation. The device comprises transmission equipment and a motor of a charge / discharge machine. The motor drives the movement of steel arms of a charge or discharge machine. The device also includes a jaw clutch positioned at the non-output end of the motor, with the other end of the jaw clutch connected to a clutch transmission instrument which has a sprocket transmission structure. And the clutch transmission instrument consists of a driving sprocket, a driven sprocket and a chain, wherein, the driven sprocket is in connection with the jaw clutch on one shaft, and the driving sprocket is connected to a hand wheel. The device provided in the invention has simple structure and convenient operation, and can retreat steel charge arms or steel discharge arms out of a heating furnace in a manual operation mode, thus preventing steel charge arms or steel discharge arms burning out.

Description

technical field [0001] The invention relates to the field of steelmaking equipment, in particular to a manual return device for a steel loading and unloading machine in a heating furnace of a steel plant. Background technique [0002] There are many heating furnaces in iron and steel plants, and the feeding and discharging methods adopt steel loading machines or tapping machines. The steel loading machine or the steel tapping machine both use two arms to load the billet into or transport it out of the heating furnace, and the two arms rely on hydraulic extension and lowering, and electric translation. [0003] If when loading steel or tapping, the loading arm or the tapping arm has stretched into the heating furnace, and a sudden power failure occurs, the loading arm or the tapping arm cannot withdraw from the heating furnace to the outside of the heating furnace. If the time is longer, it is very easy to burn the loading arm or the tapping arm. [0004] Therefore, it is n...
