Abstract
The utility model discloses a geotechnical centrifuge imbalance force monitoring device which comprises a working end, force sensors, a turning arm bearing, tension belts and a counterweight end. The number of the tension belts is 2. According to the tension belts, one end is connected with the working end, and the other end is connected with the counterweight end. The turning arm bearing is connected with the tension belts through a rolling body. The force sensors are located on both sides of the turning arm bearing. The rolling body employs a four-way equally loaded linear guide rail. With the four-way equally loaded linear guide rail, the geotechnical centrifuge imbalance force monitoring device has the advantages of simple structure and convenient installation and adjustment, and can adapt to the tension belt forms of different sections. Since the friction coefficient of the four-way equally loaded linear guide rail is small and the follow-up performance is good, the unbalanced force produced by a system can be timely and accurately transmitted to the force sensors, thus the monitoring data of the geotechnical centrifuge imbalance force monitoring device provided by the utility model are accurate.
Description
Technical field
The utility model relates to a kind of geotechnical centrifuge out-of-balance force monitoring device, particularly relate to a kind of installation easy to adjust with test data geotechnical centrifuge out-of-balance force monitoring device accurately.
Background technology
Rotation system keeps balance in rotation, be the necessary condition of hydro-extractor stable operation.Because geotechnical centrifuge is in the mismachining tolerance of production phase; The error of calculation of model weight, center of gravity; The error of calculation during counterweight trim, and the distortion of model in the hydro-extractor operational process cause error that center of gravity changes and produce or the like, makes the rotation system two ends will inevitably produce out-of-balance force.Excessive when this out-of-balance force, can cause equipment operation not steady, when serious even can bring toppling of equipment.Therefore, general geotechnical centrifuge all needs the out-of-balance force monitoring device, and its design ultimate principle is exactly to utilize the out-of-balance force size on force transducer monitoring rotation system both sides, so just requires can produce relative motion between rotary arm bearing and the rotation system.。
The technical scheme of traditional geotechnical centrifuge out-of-balance force monitoring device is following: the plane that through processing angle on circular pull strap is 90 °; On this plane, place the flat retainer of 8 groups of cylindrical rollers; Make the supporting of pull strap and pivoted arm can produce relative motion; In case out-of-balance force is arranged, this power can be delivered on the force transducer, thereby realizes the out-of-balance force monitoring.Yet traditional out-of-balance force monitoring device structure is complicated, and the adjustment trouble is installed, and Monitoring Data and gross data have than large deviation.Under the conventional art condition, the pivoted arm supporting is provided with the flat retainer guidance system of four groups of cylindrical rollers being with upper and lower two of semicircle orifice to be formed by connecting through bolt in the pivoted arm supporting, and two pull strap are passed wherein.This structure is complicated, and processing difficulties is installed the adjustment trouble.The flat retainers of 8 groups of cylindrical rollers in case not adjustment coordinate, can cause friction force to increase, can influence the transmission of out-of-balance force and cause Monitoring Data to produce deviation.
The utility model content
The purpose of the utility model is to provide a kind of installation easy to adjust in order to address the above problem, and test data is accurate, and can adapt to the geotechnical centrifuge out-of-balance force monitoring device of the pull strap form in multiple cross section.
The utility model is realized through following technical scheme:
A kind of geotechnical centrifuge out-of-balance force monitoring device; Comprise working end, force transducer, pivoted arm supporting, pull strap and counterweight end, said pull strap is 2, and an end of said pull strap is connected with said working end; The other end of said pull strap is connected with said counterweight end; Said pivoted arm supporting is connected with said pull strap through rolling body, and said force transducer is positioned at the both sides of said pivoted arm supporting, and said rolling body adopts year line slideways such as four-way.
Rolling body adopts year line slideways such as four-way.This guide rail technology maturation has extraordinary load-bearing capacity, and friction factor is low, and servo-actuated property is good, and the out-of-balance force that system produces can promptly and accurately be delivered on the force transducer.
Further improvement as the utility model is; The inboard of said pull strap is provided with locating surface; Said pivoted arm supporting is provided with installed surface with the locating surface correspondence position of said pull strap, and the both sides that said four-way etc. are carried line slideway are connected with installed surface with locating surface respectively through bolt.
During use, the requirement that provides by product processes in locating surface and the pivoted arm supporting in pull strap and processes installed surface, with high-strength bolt four-way etc. is carried line slideway and connects.
As the utility model preferably, said pull strap is circular pull strap or square pull strap.
The beneficial effect of the utility model is:
Adopt four-way etc. to carry line slideway, simple in structure, installs easy to adjust, the pull strap form of adaptation different cross section.The line slideway friction factor is little because four-way etc. are carried, and servo-actuated property is good, and the out-of-balance force that system produces can promptly and accurately be delivered on the force transducer, and the utility model Monitoring Data is more accurate.
