Spring pin force measurement mechanism used for rapidly detecting strength of ground

Abstract

The invention relates to a spring pin force measurement mechanism used for rapidly detecting the strength of ground, and belongs to the technical field of pressure measurement. The problems of large profile size, high cost and long detection time of present detection apparatuses are mainly solved in the invention. The mechanism is mainly characterized in that the mechanism comprises a spherical bearer, a pressure sensor, a pressure spring, a guide pillar plate, a supporting disc, a force measurement pin and a force measurement pin cover plate; the spherical bearer and the supporting disc are fixed together; the pressure sensor is fixed in the bottom groove of the spherical bearer; the supporting disc just facing the pressure sensor is provided with an installation through hole; the force measurement pin is a cylindrical structure with the lower end being closed and with the upper end being provided with a radical protruding edge, and the lower end of the force measurement pin traverses through the force measurement pin cover plate; and the pressure spring sleeves on the guide pillar plate, and the lower end of the pressure spring is positioned in the cylindrical structure of the force measurement pin. The spring pin force measurement mechanism has the characteristics of increase of the working efficiency of special vehicles, improvement of the working reliability, small size, simple structure and rapid detection, and is mainly used for rapidly detecting the bearing strength of the ground.

Description

technical field [0001] The invention belongs to the technical field of pressure measurement, and in particular relates to a spring pin force-measuring mechanism for quickly detecting ground strength by using an electric cylinder or a hydraulic cylinder to generate a driving force. Background technique [0002] Some special vehicles need a stable operating platform during operation. To determine whether the operating platform is stable is whether the ground hardness of the four supporting mechanisms of the vehicle is sufficient. If the ground hardness is too soft, when the settlement value exceeds the specified value during the operation time, the basic data of the operation platform will be inaccurate or unstable, which will affect the operation accuracy and results. At this time, it will take a long time to adjust the attitude of the vehicle, which will affect the operation efficiency. The heavy vehicle tilts during the lifting process, and there is a danger of vehicle cras...

Problems solved by technology

If the ground hardness is too soft, when the settlement value exceeds the specified value during the operation time, the basic data of the operation platform will be inaccurate or unstable, which will affect the operation accuracy and results. At this time, it will take a long time to adjust the attitude of the vehicle, which will affect the operation efficiency. The heavy vehicle tilted during the lifting process, there is a danger of car crash

[0003]At present, the existing ground strength detection mechanism is divided into hydraulic type and wedge type. These two types of mechanisms have large dimensions, high cost, and long detection time. If it is unqualified, it needs to be re-positioned and tested, which delays time
