Description

Technical Field

[0001] The utility model relates to the technical field of bridging devices, in particular to an anti-arching bridging device for a sintering machine trolley. Background Art

[0002] The sintering trolley is the main operating component of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine. It receives the sintering mixed material in the upper horizontal section, and returns to the head wheel after preheating, ignition, sintering, cooling, and turning over, forming a transmission cycle to achieve the purpose of sintering materials. A bridging device is used when connecting the sintering machine trolleys, but the existing bridging device still has certain defects when used.

[0003] The defects of the bridging device in the prior art are:

[0004] At present, patent document CN217504343U discloses a sintering machine trolley anti-arching and bridging device, comprising: a crossbeam, which is fixed at the bottom of a movable funnel beam located at the tail of the sintering machine; two pressure wheels, which are respectively fixed on both sides of the bottom of the crossbeam, and the two pressure wheels are suitable for abutting against the top of the flipped sintering machine trolley; when the star wheel pushes the trolley, the pressure wheels act on the top of the sintering machine trolley, and the direction of the thrust between the star teeth and the trolley is changed through the action of the pressure wheels, so that the front and rear sintering machine trolleys are smoothly connected, ensuring that the sintering machine trolley passes the curved track smoothly, and the sintering trolley anti-bridging and arching device overcomes the upward lifting force of the star wheel tooth plate on the sintering machine trolley clamping wheel when the tail star wheel pushes the trolley, and effectively restricts the occurrence of bridging and arching of the front and rear sintering machine trolleys.

[0005] When the bridging device in the above document is in use, when the star wheel pushes the trolley, the pressure wheel acts on the top of the sintering machine trolley, and the pressure wheel changes the direction of the thrust between the star teeth and the trolley, so that the front and rear sintering machine trolleys are smoothly connected, ensuring that the sintering machine trolley passes the curved track smoothly. The sintering trolley anti-bridging and arching device overcomes the upward lifting force of the star wheel tooth plate on the sintering machine trolley clamping wheel when the rear star wheel pushes the trolley, and effectively restricts the occurrence of bridging and arching of the front and rear sintering machine trolleys. However, it is difficult for the staff to adjust the bridging device during use, which makes the bridging device cumbersome to install and inconvenient for the staff to use. Utility Model Content
