Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of centering and anti-dropping of a spherical rotating joint of a step-type heating furnace for steel rolling, and in particular to a multi-centering and anti-dropping structure of a spherical rotating joint of a step-type heating furnace. Background Art
[0002] Walking beam heating furnace is a kind of equipment widely used in steel production process to heat metal billets to the temperature required for rolling or forging. In such heating furnace, walking beam system is used to push and support the metal billets in the furnace so that they are heated evenly. Walking beam system consists of a series of horizontal beams and longitudinal beams, which are connected by headers. The connection between the headers and beams uses ball swivel joints to adapt to the complex thermal expansion and contraction and movement requirements in the heating furnace.
[0003] This structure is applied to the multi-centering and anti-detachment structure of the ball rotating joint of the walking header of the steel rolling walking heating furnace. This structure can ensure that the ball rotating joint is accurately positioned and moves along the axial trajectory. It can not only prevent eccentric operation from affecting the service life, but also prevent the ball rotating joint from being disengaged and causing equipment accidents in an emergency.
[0004] At present, the walking-beam heating furnace walking coupling mechanism adopts three sets of upper, middle and lower ball rotating joints. Only the middle ball rotating joint is provided with a centering device and a guide frame to prevent the ball rotating joint from being eccentric. There is no centering device in the upper and lower sets.
[0005] There is no centering device in the upper and lower groups, and there is eccentricity between the upper and lower groups, which affects the service life. After long-term high-pressure operation and wear, the joints will become detached, causing serious equipment accidents.
[0006] Therefore, it is urgent to design a multi-centering anti-detachment structure for the ball rotating joint of the heating furnace stepping header to solve the problem of eccentricity affecting the service life and long-term high-pressure operation and wear causing the joint to detach, resulting in serious equipment accidents.

[0022] The centering and anti-slip device mainly includes a shell, an elastic element, a fixing device and an adjustment mechanism; the shell is usually made of high-strength material to provide sufficient rigidity and durability to protect the elastic element and other components inside. The elastic element is located inside the device and is mainly used to absorb and offset position deviations. The type and configuration of the elastic element determine the performance and scope of application of the centering device. The fixing device is used to install the centering device in the mechanical system to ensure its stability and reliability. The adjustment mechanism includes some fine-tuning devices to allow fine adjustments during installation and operation to ensure that the equipment remains aligned during operation.
[0023] The upper centering and anti-slipping device 1 is installed at the connection position between the upper header 4 and the upper part 1.1 of the header connecting pipe. The upper centering and anti-slipping device 1 is used to center and anti-slip the connection position between the upper header 4 and the header connecting pipe to prevent equipment damage caused by eccentricity.

[0025] The lower centering anti-slip device 3 is installed at the connection position between the lower header 6 and the lower part 3.1 of the header connecting pipe. The lower centering anti-slip device 3 is used to protect the connection position between the lower header 6 and the lower part 3.1 of the header connecting pipe to prevent eccentricity from damaging this place, so that the fluid in the upper header 4 can smoothly enter the lower header 6.
