Description

Piping lane module focus detecting system

Technical Field

The invention belongs to the field of hoisting equipment, and particularly relates to a pipe gallery module gravity center detection system.

Background

At present, a pipe gallery is widely applied to various factories in the petrochemical industry, and a plurality of pipes are centralized together and arranged along equipment or a factory building, and are mainly supported by a support in the air to form a corridor of the pipes. In order to improve the construction quality of piping lane project, reduce the incident, shorten construction cycle, a lot of piping lane project are divided into several piping lane modules and are designed and built, under the restriction of module maximum size, with whole section piping lane along level and vertical segmentation, the essential element of piping lane module can accomplish design and manufacturing in the workshop to the module form is delivered to the scene and is assembled. The concrete weight and the centre of gravity position of pipe gallery module are obtained through theoretical calculation when the design, and are not very accurate, before the on-the-spot equipment, need carry out actual measurement, otherwise when drawing, hoist and combine the pipe gallery module, the condition that slope, local overload and structure are unstable probably appears, are unfavorable for long-term use and the maintenance of pipe gallery, have the potential safety hazard moreover.

At present, it is more difficult to the focus measurement of piping lane module at the scene, mainly still utilizes the finite element method to carry out numerical analysis and simulation when the design, lacks the research to on-the-spot actual measurement method, and the result accuracy of the focus position that consequently obtains is lower, in order to guarantee that the piping lane module hoist and mount and connect going on smoothly at the scene, needs urgently to provide a neotype piping lane module focus detecting system and solves above-mentioned problem.

Disclosure of Invention

The invention aims to provide a pipe gallery module gravity center detection system, which is characterized in that a plurality of hydraulic jacks and weight sensors are reasonably arranged below a pipe gallery module to jack up the whole pipe gallery module, and then the gravity center position of the pipe gallery module is calculated according to the relative position coordinates and the load value of each weight sensor.

In order to achieve the purpose, the invention adopts the following technical scheme: a gravity center detection system for a pipe gallery module comprises a weighing sensor, a hydraulic jack, a support frame, a signal processing circuit, an RS485 serial bus and computer software. The support frame is used for supporting the piping lane module before detecting, weighing sensor install and constitute a detecting element at hydraulic jack's top, according to the specification of piping lane module, generally at the symmetrical 10 ~ 28 detecting element that arrange in piping lane module below, every detecting element has self relative position coordinate, when beginning to detect, all detecting element's hydraulic jack is with the upwards jack-up of piping lane module simultaneously, make the piping lane module rise and break away from the contact with the support frame from the support frame, weighing sensor on every detecting element sends weight information for the computer through RS485 serial bus this moment, computer software is according to every detecting element's relative position coordinate and load value, calculate the focus position and the total weight of piping lane module.

The invention has the beneficial effects that: can be at the focus position and the total weight of on-the-spot actual measurement piping lane module, measuring result is accurate, can regard as the important parameter index of piping lane module, avoids the slope that the piping lane module probably appears when pulling, hoist and combine, local overload and the unstable condition of structure, effectively guarantees going on smoothly of piping lane module at on-the-spot hoist and mount and integration.
