Rapid measuring method for lifting-trolley-wheel perpendicular divergence

Abstract

The invention discloses a rapid measuring method for lifting-trolley-wheel perpendicular divergence. The method includes the steps that a measuring face of a frame-type level meter is attached to the perpendicular plane of a wheel, a leveling bubble of the frame-type level meter is adjusted to be located at the middle position, and the measuring basis is determined; the measuring face and an upper measuring point and a lower measuring point of the perpendicular plane of the wheel are selected, the distance is measured, and according to the slant angle of a bubble of a main water level device of the frame-type level meter, a feeler gauge is added to the attaching face of the upper measuring point and the lower measuring point; the practical perpendicular divergence angle of the wheel is calculated according to the distance between the upper measuring point and the lower measuring point and the thickness value of the inserted feeler gauge, and is compared with the specified perpendicular divergence angle of the wheel, and if the difference exists, the perpendicular divergence amount of the wheel needs to be adjusted. The method is not limited by presence and absence of a measuring hole and measurement environment vibration, the measuring accuracy and the measuring efficiency are improved, the lifting-trolley-wheel perpendicular divergence amount is grasped in time, and safe operation of a lifting trolley is guaranteed.

Description

technical field [0001] The invention relates to a method for quickly measuring the vertical deflection of a crane traveling wheel. Background technique [0002] The vertical deflection angle of the crane crane wheel is the main monitoring parameter of the installation angle of the crane crane wheel, and the measurement of the vertical deflection of the wheel is a safety monitoring method for an important component in the crane crane manufacturing and maintenance technology. One of the main causes of rail gnawing during the operation of cranes is that the vertical deflection of the wheels exceeds the standard. Therefore, it is particularly important to be able to measure the vertical deflection of the wheels simply and conveniently. Usually, the vertical deflection of the wheels of the large and trolley running mechanism of the crane is measured using theodolite. Most of them do not have this measuring hole, which brings difficulties to the actual measurement operation; in a...

Problems solved by technology

Usually, the vertical deflection of the wheels of the large and small trolley running mechanisms of the crane is measured using theodolite, and the wheel bearing seat is of the web plate boring type. During the measurement, Φ18 measuring holes need to be drilled on the web, but the actual use of the crane Most of them do not have this measuring hole, which brings difficulties to the actual measurement operation; in addition, even if there is a measuring hole, the vibration caused by the operation of other cranes on the same span when using the theodolite for measurement generally exceeds the working conditions of the theodolite, making it impossible to adjust The theodolite finds the reference point, which seriously affects the measurement accuracy; at the same time, when there are measurement holes and the working conditions meet the measurement requirements of theodolite, the theodolite adjusts the reference, selects the measurement point, arranges the measuring ruler, etc. It is cumbersome and requires two people to cooperate to complete the whole The measurement work makes the measurement time longer and the measurement efficiency is low
