Description

Technical Field

[0001] The present invention relates to a device for replacing a burner of a hot rolling heating furnace. Background Art

[0002] At present, the method of replacing the burner of a hot rolling heating furnace uses a crane for hoisting, without special installation tools, and mainly installs it directly after calibration based on manual experience. The existing method not only has low safety and low installation accuracy, but also is not conducive to hoisting operations due to the narrow space near the heating furnace, thus prolonging the operation time and greatly reducing the installation efficiency. Summary of the Invention

[0003] To solve the problems existing in the existing installation method, the present invention provides a device for replacing a burner of a hot rolling heating furnace, which has a simple structure, is safe and reliable, is easy to operate, and has no energy consumption.

[0004] The technical solution adopted by the present invention is a device for replacing a burner of a hot rolling heating furnace, which includes a hoisting frame with moving wheels and a steering mechanism. A positioning pin is horizontally arranged on the hoisting frame. A front hoisting mechanism and a rear hoisting mechanism are arranged at intervals on the positioning pin. The outer end of the positioning pin is inserted into the upper slot of the installation position of the heating furnace burner to provide a fulcrum for the activities of the front hoisting mechanism and the rear hoisting mechanism. The front hoisting mechanism includes a front hoisting slider that slides along the positioning pin. A fixed pulley driven by a rocker is arranged in the front hoisting slider. The fixed pulley hangs a movable pulley through a steel wire rope. A hoisting belt is hung on the axle of the movable pulley. The rear hoisting mechanism includes a rear positioning and fixing slider. A fixed pulley driven by a rocker is arranged in the rear positioning and fixing slider. The fixed pulley hangs a fastener through a steel wire rope. The lower end of the fastener forms a fixed clamp. An upper rocker and a lower rocker are respectively arranged on the upper and lower parts of the fastener. Rotating the upper rocker and the lower rocker drives the fixed clamp of the fastener to open and close.

[0005] When the present invention works, the hoisting belt is used to complete the lifting and lowering of the front end of the heating furnace burner; the rear end of the burner is clamped by the lower fixed clamp to ensure that the front and rear ends of the burner are kept horizontal; the whole device for replacing the burner of the hot rolling heating furnace uses universal wheels for movement, and the steering device controls the single rear wheel to adjust the direction, and each wheel is equipped with a positioning brake to fix the position of the device to achieve the purpose of accurate positioning. Compared with the existing burner replacement scheme, the present invention has the following advantages: When installing and maintaining the burner of the hot rolling heating furnace, there is no need for a crane to hoist and transport, and a single person can operate on the ground. Insert the positioning pin into the upper slot of the installation position of the heating furnace burner, and adjust the front hoisting mechanism and the rear hoisting mechanism to lift the burner to an appropriate position. The installation method adopted by the device of the present invention is safe and reliable, has no energy consumption, and significantly improves the installation and maintenance efficiency of the heating furnace burner on the premise of saving space and manpower.

Embodiment

[0007] A device for replacing a burner of a hot rolling heating furnace, as shown in Figure 1 , 2 , 3, includes a lifting frame 6 having moving wheels 4 and a steering mechanism 5. A positioning pin 1 is horizontally arranged on the lifting frame 6. A front lifting mechanism 2 and a rear lifting mechanism 3 are arranged at intervals on the positioning pin 1. The outer end of the positioning pin 1 is inserted into the upper slot of the installation position of the burner of the heating furnace to provide a fulcrum for the activities of the front lifting mechanism and the rear lifting mechanism. The front lifting mechanism includes a front lifting slider 22 that slides along the positioning pin 1. A fixed pulley 20 driven to rotate by a rocker 21 is arranged in the front lifting slider 22. The fixed pulley 20 hangs a movable pulley 23 through a steel wire rope. A lifting belt 24 is hung on the axle of the movable pulley 23. The rear lifting mechanism 3 includes a rear positioning and fixing slider. A fixed pulley 31 driven to rotate by a rocker 30 is arranged in the rear positioning and fixing slider. The fixed pulley 31 hangs a fastener 33 through a steel wire rope. The lower end of the fastener 33 forms a fixed clamp 36. An upper rocker 32 and a lower rocker 34 are respectively arranged on the upper and lower parts of the fastener. Rotating the upper rocker 32 and the lower rocker 34 drives the fixed clamp 36 of the fastener to open and close along the guide rod 35.

[0008] On the premise of saving space and manpower, the present invention is safe and reliable, without energy consumption, and can significantly improve the installation and maintenance efficiency of the burner of the heating furnace.
