An arc gate hinge with an opening sensor and its assembly and positioning method

Abstract

The invention discloses an arc-shaped gate hinge with an opening sensor, which comprises a fixed hinge seat, and the fixed hinge seat is hinged to a movable hinge seat through a hinge shaft; A bearing device is installed at the position, and the bearing device includes a bearing inner ring and a bearing outer ring. The bearing inner ring is fixedly set on the outside of the hinge shaft, and the radial limit device of the inner ring is used to keep it in constant contact with the hinge shaft. Fixed, one end of the inner ring of the bearing is limited by the shaft shoulder processed on the hinge shaft, and the other end is fixedly installed with an end cover of the inner ring bearing. The arc-shaped gate hinge structure can realize gate opening detection, and adopts a built-in sensor, which prolongs the service life of the sensor and improves its detection accuracy.

Description

technical field [0001] The invention relates to the technical field of installation of arc-shaped gate hinges in water conservancy and hydropower projects, in particular to an arc-shaped gate hinge with an opening sensor and an assembly and positioning method. Background technique [0002] In modern water conservancy and hydropower projects, the arc gate does not need a gate slot, the water channel is continuous, and the water flow is good. It is the most economical door type among many gates, so arc gates are widely used. In the later service of the arc gate, the flood discharge size of the orifice is adjusted by adjusting the opening of the gate, and the gate opening is adjusted, and the sensor signal is transmitted to the control room, which is conducive to precise operation. [0003] In the past, the arc gate opening sensor was generally displayed through the height position, and it was installed on the gate body structure of the gate, because it was exposed and it was ...

Problems solved by technology

[0004] For example: CN 105509629 A discloses an arc gate opening detection device and method. The opening detection device adopts an angle detection device, and the angle detection device adopts an inclination sensor, which is directly installed on the fan blade of the arc gate. On the support arm, the opening detection device with this structure cannot adapt to the harsh environment. After long-term use, the accuracy is not high, and the service life cannot be guaranteed.

[0005] In CN 202371006 U, a curved gate hinge using spherical bearings is disclosed, but the middle hinge cannot detect the angle of the gate
