Abstract
The invention discloses an inner width detection ruler which is formed by the combination of a compression spring, a fixed scale, a sliding scale, an extension bar for the fixed scale, an extension bar for the sliding scale and a detection head, wherein the extension bar for the fixed scale, the fixed scale, the extension bar for the sliding scale and the sliding scale are connected by screw threads, and an opening which is in line with the size of the sliding scale is arranged on the fixed scale; and the sliding scale is arranged in the opening and is in slide connection with the fixed scale, a limit screw used for fixing the position of the sliding scale is arranged on the fixed scale, a stop screw used for preventing the sliding scale from falling or rotating is arranged on the sliding scale, and the compression spring is positioned between the sliding scale and the fixed scale so as to ensure that both ends of the detection ruler can respectively closely contact two detection points. The inner width detection ruler has the advantages of simple structure and convenient use, and can reduce the labor intensity of measurement work.
Description
Technical field
The present invention relates to a kind of engineering measurer, particularly a kind of inner width detection ruler.
Background technology
The Hydraulic and Hydro-Power Engineering bulkhead gate groove is installed, and needs to measure backbone, anti-rail, verticality, gate slot width and the backbone of seal plate, anti-rail, the seal plate deviation with respect to installation reference line.VTOL (vertical take off and landing) lift car track is installed also needs similar measurement.Generally, use existing measurer to finish above-mentioned detection, need track to both sides to detect respectively at least after, integrate again and draw testing result.Operate easyly inadequately, and increased high-rise working intensity.
Summary of the invention
At the problems referred to above, the invention provides a kind of inner width detection ruler, utilize this inner width detection ruler just can obtain the distance of both sides " cell wall ", deviation, the verticality of relative installation reference line simultaneously to a side reading.Reduce operation steps, and reduced high-rise working intensity.
For this reason, the present invention adopts following technical scheme: a kind of inner width detection ruler, combine by compression spring, scale, slide rule, scale extension bar, slide rule extension bar and gauge head, scale extension bar, scale, all adopt between slide rule extension bar, the slide rule and be threaded, scale is provided with and the corresponding hole of slide rule size, compression spring is housed in the hole, slide rule places in the hole and can slide in the hole, scale is provided with the fixedly stop screw of slide rule position simultaneously, slide rule is provided with the stop screw that prevents that slide rule from coming off or rotating, and is the basic hole system clearance fit between slide rule and the scale.
Wherein, blade is provided with a millimeter scale, can estimate and read to 0.5mm, and gauge head has 2 its effective lengths to be 20.00mm, and the end makes it not easy to wear through thermal treatment, and scale dish seat end is also equally through thermal treatment.
The present invention is simple in structure, integrates multiple measurement function, and it is very convenient to use, and has reduced labour intensity.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
Fig. 2 is an embodiment of the invention synoptic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done and to be described in more detail.
Consult Fig. 1, a kind of inner width detection ruler, combine by compression spring 8, scale 1, slide rule 3, scale extension bar 7, slide rule extension bar 2 and gauge head 4, scale extension bar 7, scale 1, all adopt between slide rule extension bar 2, the slide rule 4 and be threaded, scale 1 is provided with and the corresponding hole of slide rule 3 sizes, compression spring 8 is housed in the hole, slide rule 3 places in the hole and can slide in the hole, scale 1 is provided with the fixedly stop screw 5 of slide rule 3 positions simultaneously, slide rule 3 is provided with the stop screw 6 that prevents that slide rule from coming off or rotating, and is the basic hole system clearance fit between slide rule 3 and the scale 1.
Wherein, scale 1, slide rule 3, stop screw 5, stop screw 6, compression spring 8 are assembled into as a whole, are called main scale.The long 360.00mm of scale, the long 185.00mm of slide rule, side head length 20.00mm scale extension bar 7 is 400.00mm, slide rule extension bar 2 has three kinds of sizes, is respectively 100.00mm, 200.00mm, 400.00mm.According to the groove width physical size, select the slide rule extension bar 2 of different length to be made up respectively during use with scale extension bar 7.
Between slide rule 3 and the scale 1 compression spring 8 being set, is for survey chi two ends are contacted closely with two measuring point places respectively.
In addition, slide rule external diameter Φ 16mm, long 185.00mm, the segment length 80～85mm that wherein leads is carved with millimeter scale on remaining 105～100mm blade and is exposed at outward outside the scale circular hole, during work, manually pushes in scale Φ 16 holes, ejects outside the hole by spring force.
Consult Fig. 2, except that gauge head 4, all chi Duan Jun are carved with a millimeter scale in elongated scope, and after can guaranteeing that each chi section is connected mutually, pedal line place in the drawings reads size.No matter how each chi section makes up, and length and all known is assumed to be A, and a side reads L behind the reading at slide opening aperture place 9 in the drawings, and then opposite side is of a size of A-L.
When surveying rail or cell wall verticality, the difference of different elevation measured value L1 is the verticality absolute value of rail or cell wall, and this absolute value is relative verticality with the ratio of two measuring point distances up and down.
When the reference for installation linear distance of pedal line and gate master, anti-rail or elevator rail was known, the difference of the reading L1 at place, slide opening aperture 9 and design load was the deviation with respect to datum line on the scale.
Wherein, pedal line can replace with transit.Reading is comparatively convenient when pedal line hangs on the L position.And when not using the scale extension rod, L ≈ 0.45m; When using the scale extension rod, L ≈ 0.8m.
In addition, installing gauge head 4 additional at scale 1 or scale extension bar 7 dish seat ends can the gaging hole internal diameter, but also gaging hole with respect to the deviation of datum line.
Therefore use the present invention, the reading L1 at place, a slide opening aperture 9 can obtain 2 sizes about pedal line simultaneously, has reduced by a side measuring operation, thereby has simplified surveying work, has reduced high-rise working intensity.
