Description

3D detection device after TRT blade assembly is accomplished

Technical Field

The utility model relates to the technical field of blast furnace smelting, in particular to a three-dimensional (3D) detection device for TRT blades after assembly.

Background

The TRT, namely the blast furnace gas residual pressure turbine power generation device, utilizes the pressure energy and heat energy of byproducts (blast furnace top gas) of blast furnace smelting to enable the gas to work through a turbine expander, converts the gas into mechanical energy and then converts the mechanical energy into electric energy.

TRT rotor blades are typically composed of a single stage or a dual stage. Because blast furnace gas contains chlorine, sulfur dioxide and dust particles, blades are damaged due to erosion and corrosion during rotor operation, and the blades are required to be disassembled for repair or replaced by new blades and then reinstalled for use.

The fit clearance between the blade tips and the bearing cylinders is typically 1.5mm to 2mm when the TRT rotor is installed. Due to manufacturing errors, assembly errors and the like, there is a certain deviation in the blade tip dimensions after the TRT rotor is reassembled.

When the traditional detection method is adopted, the bearing cylinder is required to be covered to check the fit clearance, and the problems caused by the method are as follows: if the blade top size is higher than the allowable value, the cylinder bearing cover is not on; the blade and the bearing cylinder are matched in a closed mode, after the bearing cylinder is covered, the sight line is poor, and the detection operation is inconvenient; if the deviation size of the leaf tops is polished, the bearing cylinder is heavy, the hoisting is time-consuming and labor-consuming, and She Dinggao-degree size non-uniformity can not be timely and accurately detected; if the blade top size is lower than the allowable value, the blade needs to be disassembled again for reworking; if the polishing amount is too large, the dynamic balance test of the rotor is needed to be carried out again, so that the construction period is prolonged and the labor intensity is increased.

In the prior art, a Chinese patent with a publication number of CN105004241A is proposed to solve the technical problems, and the technical scheme disclosed in the patent document is as follows: a measuring device for a rotor blade. Comprises a rolling bearing, a supporting rod, a connecting part, a flat ruler, a main bracket and a base. The bottom end of the supporting rod is provided with a rolling bearing, the top end of the supporting rod is provided with a connecting part and connected with one end of a flat ruler, the other end of the flat ruler is provided with a bolt and connected with the top end of the main support, the bottom end of the main support is provided with a base, and the rolling bearing is arranged below the base. According to the rotor blade measuring device, the inner conical surface of the bearing cylinder is simulated outside, and the inner conical surface of the bearing cylinder can be detected quickly on the premise that a hanging cover is not needed, so that measurement becomes simple, quick and effective, but the device is used for carrying out manual measurement by using a flat ruler, so that the measurement error is large, moreover, the accuracy measurement of the rotor blade in the running state cannot be carried out, and certain limitation exists when the device is used.
