Abstract
The utility model discloses a high precision contraction meter having digital display, which is formed by a steel rule, a hook, a spring, a slide block, a dial gauge and a frame body. The high precision contraction meter having digital display is characterized in that the ruler clamp of the steel rule fixed at the front end of the frame body is provided with a pressured rule coil, a rule protect pad and a positioning pin. A spherical surface hanging body cavity which is connected with a connecting sleeve on a pre-burying pin is arranged at the rear end of the frame body. A sliding tube, a drive mechanism for finely adjusting the position of the slide block and the tension of the string and a force measuring scribed line are arranged in the spherical surface hanging body cavity, the contact plate of the slide block tightly sticks on the contact tip of the digital display dial gauge which leads out the interface of digital output. The utility model has the advantages of processing data by a computer with high accuracy in measurement, and is suitable for the measuring of distortion and shift in subterranean and above work.
Description
The method that the utility model belongs to the employing electricity is the metering outfit of feature, is a kind of wide range, high-precision distortion, displacement surveying instrument.
At present, in underground works, measure the point-to-point transmission relative displacement of surface, tunnel, often adopt convergence gauge.The structure of used convergence gauge is, is made up of steel ruler, hook, spring, slide block, big stroke dial gauge, steel ruler is hooked between two measuring points of pre-testing, the tensioning steel ruler, fine setting slide block, compression spring, when reaching certain spring tension, survey and read the dial gauge reading; After malformation, displacement, use method again, to survey and read the dial gauge reading, twice reading difference is deflection.This convergence gauge, easy to use, the precision height, failure rate is low, therefore is widely used.But, when the data that existing convergence gauge records with mechanical direct-reading dial gauge will be carried out Computer Processing, need make extensive work, can not satisfy the requirement of modern surveying.
The purpose of this utility model is, adopts the little measurement data of reading of digital display centimeter, improves the structure of folder chi device, designs novel steel ruler hook hinge, improving measuring accuracy, and realizes the Computer Processing of measurement data.
Digital display type high precision convergence gauge of the present utility model, by steel ruler, hook, spring, slide block, dial gauge, support body is formed, it is characterized in that, the support body front end fixedly folder chi device of steel ruler is provided with the nose bar screwed pipe, protect foot pin sheet and tommy, the support body rear end is provided with and is used for the spherical hinge that is connected with pre-buried pin, be provided with slip pipe in the support body cavity, be provided with the screw rod that is used to finely tune slide position and spring tension in the slip pipe, the screw rod end is connected with transmission gear and handwheel, slide block is connected on the screw rod with internal thread, slide block and slip pipe are provided with guide rail one sliding wing and slip ring, sliding wing and slip ring are provided with the dynamometry groove, slip pipe is provided with the contact that touch panel is adjacent to digital display centimeter, and digital display centimeter is fixed on the support body, and draws digital output interface.
The using method of digital display type high precision convergence gauge of the present utility model is, the steel ruler of digital display type high precision convergence gauge is pulled out, hook is connected with the pre-buried pin of measuring point with spherical hinge, the tommy of folder chi device is inserted suitable position, hole on the steel related scale, rotate handwheel again, the tensioning steel ruler when the dynamometry groove aligns on sliding wing and the slip ring, reads reading on the digital display centimeter; Twice survey measurements poor is displacement, deformation values.
The utlity model has following advantage: the line that spherical hinge can adapt between the measuring point of various directions and angle is measured, and the spherical hinge corner is, level ± 45 ° are vertical+90 °～-45 °; Folder chi device can be realized the location, be clamped in one, and register pin can spring into the chi hole automatically, and the location is convenient, and the folder chi is firm, does not hinder steel ruler; The dynamometry groove has two groups, and corresponding spring tension force is 9 and 11 kilograms, and (baseline≤10 meter are with 9 kilograms with interior measurement applicable to 30 meters of base length; Baseline 〉=10 meter are with 11 kilograms); Have digital output interface, the available computers deal with data; By position, the hole skimming reading of perforation steel ruler, digital display centimeter is little to be read, and has realized wide range, high precision and electromechanical integration; Reading accuracy is at ± 0.01mm, and measurement accuracy is at ± 0.06mm.Be applicable to the underground engineering wall rock deformation measurement, the distortion, the displacement that also can be used between surface structures are measured.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of digital display type high precision convergence gauge.
As seen from the figure, digital display type high precision convergence gauge is made up of steel ruler, hook 2, spring, slide block, digital display centimeter, support body, it is characterized in that the support body 8 front ends fixedly folder chi device 6 of steel ruler 3 are provided with nose bar screwed pipe 5, protect foot pin sheet 7 and tommy 4; The support body rear end is provided with and is used for the spherical hinge 14 that is connected with pre-buried pin upper joint sleeve tube 1, is provided with slip pipe 9 in the support body cavity, is provided with the screw rod 17 that is used to finely tune slide position and spring 18 tension force in the slip pipe, and the screw rod end is connected with transmission gear 16 and handwheel 15; Slide block 22 usefulness internal threads are connected on the screw rod, slide block and slip pipe are provided with guide rail-cunning wing 20 and slip ring 21, and sliding wing and slip ring are provided with dynamometry groove 19, and slip pipe is provided with the contact 11 that touch panel 10 is adjacent to digital display centimeter 12, digital display centimeter is fixed on the support body, and draws digital output interface 13.
