Abstract

The invention discloses a surge shaft fast door laser range finder adjusting support and a manufacturing method. In the prior art, when a hydraulic power plant surge shaft rapid door laser range finder is installed, the angle is difficult to adjust rapidly and accurately to measure the opening degree of the rapid door. The device comprises a fixed bracket (1), an adjusting transmission mechanism (2) and a range finder fixing plate (3), the fixed bracket comprises a bracket crank arm (4), the bottom of the bracket crank arm is connected with a base, the top of the bracket crank arm is connected with a sleeve (6) through a triangular support (5), the bottom of the sleeve is provided with a rectangular opening, the adjusting transmission mechanism comprises a worm gear (8), and the worm gear (8) is connected with the base. The worm gear and a worm (9) are meshed in the rectangular opening, the worm is fixed in the sleeve, the two ends of the worm are limited through limiting screws (10), and the worm gear is installed on the bracket crank arm and fixed to the fixing plate through bolts. The laser range finder adjusting support is used for the surge shaft fast door.

Description

technical field [0001] The invention relates to the technical field of laser tools, in particular to an adjustment bracket and a manufacturing method of a laser range finder for a fast door of a surge well. Background technique [0002] The quick door of the surge shaft of a hydropower plant is a water barrier gate located between the water inlet of the hydroelectric unit and the guide vane of the volute. important role; [0003] The fast door laser rangefinder is installed above the fast door to provide the control unit with a sensor for the real-time opening of the fast door. The laser rangefinder measures the reflection of the laser beam by shooting the laser at the disc fixed on the hydraulic boom of the fast door. The opening of the fast door is calculated by returning the time of the range finder. In order to ensure that the laser can always accurately shoot to the center of the disc and reflect when the disc moves up and down with the fast door, there are strict requ...
