Problems solved by technology

[0004] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, and to provide a cardan-type expansion joint angular displacement equalization device, which solves the problem that the deformation of the cardan-type expansion joint is easily concentrated on one of the bellows, which is easy to cause the The deformation of the bellows is too large, which affects the normal operation of the expansion joint

Embodiment Construction

[0023] The present invention aims at the shortcomings of the existing Cardan expansion joints, and welds and fixes the seat plates on the pull plates of the two sets of bellows respectively. The seat plates are hinged with the connecting rods through pin shafts, and the connecting rods at both ends are then connected to the middle connecting rod. If one of the connecting rods rotates around the radial center axis of the bellows along with the deformation of the bellows, this action will drive the rotation of the middle connecting rod, thereby driving the other connecting rod to rotate in the opposite direction , which in turn drives the reverse deformation of the other bellows. To achieve the purpose of equalizing the deformation of the two bellows. The present invention will be explained and described in more detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, it is a structural diagram of a cardan type expansion joint angular dis...

Abstract

The invention relates to an angular displacement balancing device of a cardan type expansion joint. Fixed seat boards are respectively welded on pull plates of two corrugated pipes, the fixed seat boards are hinged to connecting rods by virtue of pin shafts, the connecting rods on both ends are connected to both ends of a middle connecting rod, and when the connecting rod on one side rotates alongwith the deformation of the corrugated pipe on one side, the middle connecting rod is driven to rotate by the current movement, so that the connecting rod on the other side is driven to rotate to thereverse direction, the corrugated pipe on the other side is driven to deform in the reverse direction, and the amount of deformation of the corrugated pipes on both sides is balanced. Compared with the prior art, the angular displacement balancing device is arranged, so that the condition that the deformation of the cardan type expansion joint focuses on the single corrugated pipe during operation can be avoided, and a good use value is obtained.

Description

technical field [0001] The invention relates to the technical field of expansion joints, in particular to a cardan type expansion joint angular displacement equalization device. Background technique [0002] The blast furnace air supply device is a device installed between the hot air surrounding pipe and the small tuyere sleeve. Its function is to send the hot air (1200-1350°C, 0.3-0.55MPa) generated by the hot blast stove into the blast furnace through each tuyere of the blast furnace, and at the same time spray coal powder into the blast furnace and observe the blast furnace through some special settings on the device. smelting conditions. Moreover, the air supply device should also absorb the displacement and deformation of the blast furnace and the hot blast surrounding pipe as well as the device itself due to heating by setting expansion joints. [0003] As the most commonly used expansion joint for air supply devices, the Cardan expansion joint consists of two sets ...
