Problems solved by technology

The conventional calibration device for the verticality and vertex angle of the mechanical hole forming detector has high requirements on the environment. Therefore, the testing unit needs to transport the entire system of the mechanical hole forming detector to the laboratory of the metrology institution, which cannot guarantee the quantity of the equipment in time on the project site. The value is accurate; due to the heavy weight and the particularity of the umbrella itself of the sensor itself, the connection, fixation and installation of it with the conventional angle calibration device become a calibration problem, and the measurement and calibration device will be damaged if it is not operated properly.

Abstract

The invention provides a movable mechanical pore-forming detector verticality apex angle measurement calibration device and method. The method comprises the steps of in an unfolding link, adjusting a movable support frame to an extension state, and moving one end of a movable frame to be away from a fixed frame, in a leveling link, firstly installing a sensor of the mechanical pore-forming detector on a clamping mechanism, adjusting a spiral lock catch for fixing, then placing a leveling instrument on the top plane of the fixed frame, and then adjusting a leveling device to enable the movable frame to be in contact and fixed with the bottom surface, so that the leveling instrument is in a horizontal state, and in an angle adjusting link, adjusting the hand crank of the rotating mechanism, adjusting the dividing head of an indicating mechanism to the position of 0 DEG. The calibration device comprises a movable supporting frame, a clamping mechanism at the upper end of the movable supporting frame, the indicating mechanism and the rotating mechanism. The calibration device is reasonable in structural design, high in measurement and calibration precision, convenient to move, carry and level, and the on-site measurement calibration requirements of water transportation engineering can be met.

Description

technical field [0001] Embodiments of the present invention generally relate to the technical field of metrology of engineering foundation structure testing instruments, and more specifically, relate to a measuring and calibrating device and method for verticality and apex angles of a movable mechanical hole-forming testing instrument. Background technique [0002] Cast-in-place pile drilling and large-diameter drilling techniques are widely used in high-pile wharf and port projects. As an indispensable testing instrument in the early stage of waterway engineering construction, the mechanical hole-forming detector can quantitatively give the vertical Accurate detection of verticality and apex angle is a key factor that affects the degree of deviation of foundation piles and the bearing capacity of foundation piles. In order to ensure the accuracy of the hole quality inspection data, it is of practical research and application value to regularly measure and calibrate its vert...
