Abstract

The invention discloses a device for measuring the surface shape tolerance of a curved surface lining plate of a cylindrical surface steel support, a transverse sliding groove for a longitudinal supporting plate to slide is transversely formed in a transverse supporting frame, connecting holes are formed in the longitudinal supporting plate and located on the two sides of the transverse supporting frame in a penetrating mode, and dial indicators are inserted into the four connecting holes in an embedded mode, and support columns are vertically connected to the bottom ends on two sides of the transverse supporting frame, compared with a traditional sample plate method with a fixed reference, the reference of the measurement method of the device can be changed along with a measured sample, the evaluation result is more convincing during batch measurement in a factory, and compared with a three-coordinate measurement method, although the detection precision is lower than that of the three-coordinate measurement method, however, the device is better in detection convenience, suitable for large-scale measurement and not suitable for samples measured by a traditional two-point method and a three-point method, and the method can be adopted for non-whole cylinders such as semi-cylinders, so that the device can be suitable for measurement of different measurement samples.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a device for measuring the surface shape tolerance of a curved lining plate of a cylindrical steel support. Background technique [0002] The support is a device that supports the engineering structure and transmits force. The bridge support is generally set between the upper structure (beam) and the lower structure (pier abutment) of the bridge, and transfers various loads from the upper structure to the lower structure. It can adapt to the displacement and rotation caused by factors such as live load, temperature change, concrete shrinkage and creep, so that the actual stress of the upper and lower structures conforms to the design calculation diagram. At present, cylindrical steel bearings are widely used in freight transportation. The construction of railways and passenger-cargo railways is characterized by the fact that the curved liner is in the form of a sm...
