Bilateral adjustment compensation clamping device for startup nozzle ignition system

Abstract

The invention relates to a bilateral adjustment compensation clamping device for a startup nozzle ignition system. In the bilateral adjustment compensation clamping device, support plates at the two ends are connected with U-shaped suspensions through horizontal movable pivot shafts; the end parts of the horizontal movable pivot shafts at the two ends are provided with springs; the U-shaped suspensions are connected with an inner-layer U-shaped clamping frame and an inner-layer pressure plate through an upper pivot shaft and a lower movable pivot shaft; the inner-layer U-shaped clamping frame and the inner-layer pressure plate are used for clamping a nozzle; the moving directions of the U-shaped suspensions and the U-shaped clamping frame are vertical to each other; and the end part of the lower movable pivot shaft is provided with a spring. The bilateral adjustment compensation clamping device has the characteristics that 1, the structure is simple, operation is easy and convenient since only one manual adjusting position is provided in an adjusting process, and the requirements on installation and adjusting instruments and the operation techniques of workers are not high; and 2, high functionality is realized, the nozzle can be clamped and fixed, the coaxiality of a nozzle shaft can be adjusted during installation, coaxiality errors caused by high temperatures can be compensated automatically during ignition insertion, the overall straightness accuracy meets a certain requirement, and accurate positioning ignition is realized.

Description

technical field [0001] The invention relates to a two-way adjustment compensation clamping device for an ignition system of a start-up burner. Background technique [0002] In the integrated start-up burner ignition system, to ensure the accuracy of the positioning of the burner during ignition, the straightness of the burner needs to be adjusted. In the previous burner clamping, the general opening clamping device was used, and the long hole When adjusting the straightness of the burner during installation and commissioning, only the horizontal error can be adjusted, and two-way adjustment cannot be realized. The whole device is not adjustable during operation. When the burner is deformed due to high temperature, the straightness error cannot be automatically compensated, so often It will cause a large error and make it difficult for the burner to operate when it is inserted and removed, and occasionally it will be stuck.
