Description

TECHNICAL FIELD

[0001] The utility model relates to a hole inclination measuring device for sleeper pre -buried hole. BACKGROUND

[0002] The sleeper plays a vital role in railway transportation, which not only supports and fixes the steel rail, but also enhances the safety and comfort of train operation through pressure transmission and roadbed protection. The state of the sleeper directly affects the stability and safety of the railway, so it is necessary to measure and detect it regularly.

[0003] To ensure the accurate positioning of the spikes, the hole inclination of the pre -buried hole (with a pre -buried sleeve) on the sleeper needs to be measured. The relevant standards for sleeper measurement stipulate that the distance of the pre -buried sleeve from the rail surface 120mm deep from the center line needs to be detected, that is, the distance between the center line of the pre -buried hole and the vertical line of the rail surface at a depth of 120mm.

[0004] The prior art also has a hole inclination measuring tool, but on the one hand the measuring accuracy is not high, and on the other hand the hole diameter is single, which cannot be applied to the measurement of sleepers with multiple hole diameters. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a hole inclination measuring device for sleeper pre -buried hole which can measure accurately and is suitable for pre -buried holes with multiple hole diameters.

[0006] The technical scheme of the utility model is as follows: a hole inclination measuring device for sleeper pre -buried hole comprises:

[0007] The positioning cone has a positioning conical surface for positioning along the hole of the pre -buried hole to be measured, and a through hole perpendicular to the center line thereof is provided on the positioning cone, the cross section of the through hole is a waist -shaped hole, and the length of the waist -shaped hole extends along the center line direction of the positioning cone;

[0008] The positioning shaft is sleeved in the through hole, the positioning shaft can slide in the through hole along the center line direction of the positioning cone, the positioning shaft can rotate in the through hole, the diameter of the positioning shaft is consistent with the width of the through hole, and the two ends of the positioning shaft are provided with coplanar cutting surfaces for abutting with the rail surface corresponding to the pre -buried hole to be measured;

[0009] The main ruler is rectangular and extends along the axis direction of the positioning cone, the lower end of the main ruler is movably inserted into the rectangular groove provided on the upper part of the positioning cone, the upper part of the main ruler is provided with a transverse slot extending in the width direction, a vernier scale is movably assembled in the transverse slot, and the size scale is correspondingly provided on the upper edge of the transverse slot and the vernier scale;

[0010] The measuring pendulum rod has a length of 240mm, a circular hole is arranged in the center of the measuring pendulum rod, the measuring pendulum rod can rotate around the positioning shaft by sleeving the positioning shaft through the circular hole, and the upper end of the measuring pendulum rod is hinged with the center of the vernier scale.

[0011] The positioning sleeve is arranged on the positioning cone and can slide along the axial direction relative to the positioning cone, and the lower end of the positioning sleeve is provided with a containing groove for containing the positioning shaft, and the cutting surface is flush with the lower surface of the positioning sleeve;

[0012] The positioning cone and the positioning sleeve are provided with avoiding holes for the swing of the measuring swing rod;

[0013] The locking mechanism is used for locking the positioning cone relative to the positioning sleeve after the positioning of the positioning cone and the positioning sleeve.

[0014] Further, the adjusting mechanism for adjusting the relative position between the positioning cone and the positioning sleeve is arranged between the positioning sleeve and the positioning cone. The arrangement of the adjusting mechanism can conveniently adjust the relative position between the positioning sleeve and the positioning cone, improve the adjusting efficiency and the adjusting accuracy.

[0015] Further, the adjusting mechanism comprises an adjusting screw and an adjusting screw hole arranged on the upper part of the positioning cone, and the positioning sleeve is further provided with an adjusting light hole coaxially arranged with the adjusting screw hole, and the adjusting screw is matched with the adjusting screw hole after penetrating through the adjusting light hole.

[0016] Further, the locking mechanism comprises a positioning screw hole arranged on the positioning sleeve and a positioning screw threadedly arranged in the positioning screw hole, and the front end of the positioning screw is abuttingly matched with the positioning cone.

[0017] Further, the lower end of the measuring swing rod is a measuring head in the shape of inverted T.

[0018] The hole inclination measuring device for the pre-buried hole of the sleeper has the following beneficial effects: the positioning cone surface of the positioning cone can be used for the center positioning of the pre-buried hole with different hole diameters, so that the center line of the positioning shaft can coincide with the center line of the pre-buried hole, then the coincidence of the cutting surface at the two ends of the positioning shaft and the rail surface can ensure that the center line of the positioning shaft coincides with the rail surface, and the top end of the lower half of the measuring swing rod is just at the depth of 120 mm of the pre-buried hole, so as to ensure the accuracy of the measurement. The top end of the lower half of the measuring swing rod can simulate the inclination angle of the pre-buried hole, and the offset distance of the upper half is the offset distance of the lower half after the conversion of the upper half of the measuring swing rod which is also 120 mm long. The offset of the upper half is the offset of the lower half, that is, the inclination of the pre-buried hole. When the position of the positioning shaft is determined, the lower surface of the positioning sleeve also coincides with the rail surface. At this time, the positioning sleeve and the positioning cone can be locked into an integrated structure by the locking mechanism, so as to prevent the position change of the two from causing the positioning shaft to deviate from the set position, and further ensure the accuracy of the subsequent measurement. The design of the vernier can accurately measure the accuracy to 0.01 mm, and further improve the accuracy of the measurement. BRIEF DESCRIPTION OF DRAWINGS

[0028] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0029] An embodiment of the hole inclination measuring device for railway sleeper pre-embedded holes according to this utility model: (e.g.) Figures 1-5 As shown, the hole inclination measuring device for railway sleeper pre-embedded holes includes a positioning cone 2, a positioning shaft 3, a main scale 4, a vernier scale 5, a measuring pendulum rod 6, a positioning sleeve 7, and a locking mechanism.

[0030] like Figure 2 As shown, the positioning cone 2 has a positioning cone surface 21 for positioning and engaging with the pre-embedded hole 11 to be measured. The positioning cone 2 is provided with a through hole 22 perpendicular to its center line. The cross-section of the through hole 22 is an oblong hole. The length of the oblong hole extends along the center line of the positioning cone 2, which can ensure that the positioning shaft 3 moves along the length direction of the oblong hole, so that the positioning shaft 3 can still be in the center position when the pre-embedded hole 11 has different diameters.

[0031] like Figure 2 As shown, the positioning shaft 3 is inserted into the through hole 22. The positioning shaft 3 can slide along the center line of the positioning cone 2 within the through hole 22 and can rotate within the through hole 22. The diameter of the positioning shaft 3 is the same as the width of the through hole 22. The two ends of the positioning shaft 3 have coplanar cut surfaces 31 for fitting with the bearing surface 12 corresponding to the pre-embedded hole 11 to be measured. The middle section of the positioning shaft 3 is cylindrical and can move up and down within the through hole 22 and rotate around itself. The lower half of both ends of the positioning shaft 3 is cut off to form cut surfaces 31. The cut surfaces 31 at both ends are coplanar and can fit with the bearing surface 12 simultaneously, thereby positioning the center line of the positioning shaft 3 on the bearing surface 12. This ensures that the center of the measuring pendulum 6 is exactly on the bearing surface 12, and thus ensures that the measuring head 62, which is 120mm away from the center, is exactly at a depth of 120mm in the pre-embedded hole 11.

[0032] like Figure 1 ,2 As shown in the figure, the main ruler 4 is rectangular, and extends along the axis direction of the positioning cone 2. The lower end of the main ruler 4 is movably inserted into the rectangular groove 23 provided on the upper portion of the positioning cone 2. The upper portion of the main ruler 4 is provided with a transverse slot 42 extending along the width direction. The vernier ruler 5 is movably assembled in the transverse slot 42. The vernier ruler 5 and the upper edge of the transverse slot 42 are provided with size scales corresponding to each other. The structure of the upper portion of the main ruler 4 and the structure of the vernier ruler 5 are changed from the vernier caliper, so as to achieve the purpose of 0.01-0.02mm precision and improve the reading accuracy.

[0033] As shown in the figure, Figures 2-4 The length of the measuring pendulum 6 is 240mm. The center of the measuring pendulum 6 is provided with a circular hole, which is sleeved on the positioning shaft 3 so that the measuring pendulum 6 can rotate around the positioning shaft 3. The upper end of the measuring pendulum 6 is hinged to the center of the vernier ruler 5, so as to ensure that the center of the upper end of the measuring pendulum 6 is at the 0 scale line of the vernier ruler 5. In this embodiment, the scale lines of the vernier ruler 5 and the main ruler 4 are designed to gradually increase from the middle to both sides, so as to realize the reading of the distance away from the center line.

[0034] As shown in the figure, Figure 2 The positioning sleeve 7 is movably sleeved on the positioning cone 2. The positioning sleeve 7 is a circular cap-shaped structure with an open lower end. The positioning sleeve 7 and the positioning cone 2 can slide relative to each other along the axis direction. The lower end of the positioning sleeve 7 is provided with a containing groove 71 for containing the positioning shaft 3. The cutting surface 31 is flush with the lower surface of the positioning sleeve 7. The positioning cone 2 and the positioning sleeve 7 are provided with an avoiding hole 24 for the measuring pendulum 6 to swing in it.

[0035] The locking mechanism is used to lock the positioning cone 2 relative to the positioning sleeve 7 after the positioning of the positioning cone 2 and the positioning sleeve 7. An adjusting mechanism is arranged between the positioning sleeve 7 and the positioning cone 2 for adjusting the relative position between the positioning cone 2 and the positioning sleeve 7. The arrangement of the adjusting mechanism can facilitate the adjustment of the relative position between the positioning sleeve 7 and the positioning cone 2, and improve the adjustment efficiency and accuracy. The adjusting mechanism comprises an adjusting bolt 8 and an adjusting threaded hole 25 provided on the upper portion of the positioning cone 2. The positioning sleeve 7 is further provided with an adjusting light hole 72 coaxially arranged with the adjusting threaded hole 25. The adjusting bolt 8 passes through the adjusting light hole 72 and cooperates with the adjusting threaded hole 25. The locking mechanism comprises a positioning threaded hole 73 provided on the positioning sleeve 7 and a positioning bolt 9 screwed in the positioning threaded hole 73. The front end of the positioning bolt 9 abuts against the positioning cone 2. The lower end of the measuring pendulum 6 is a measuring head 62 in the shape of inverted T.

[0036] The hole inclination measurer for the pre-buried hole of the sleeper can be used for center positioning of the pre-buried hole 11 with different hole diameters, the center of the positioning shaft 3 can coincide with the center line of the pre-buried hole 11, then the coincidence of the cutting surface 31 at both ends of the positioning shaft 3 and the rail bearing surface 12 ensures that the center line of the positioning shaft 3 coincides with the rail bearing surface 12, the top end of the lower half of the measuring swing rod 6 is just at the depth of 120mm of the pre-buried hole 11, thereby ensuring the accuracy of measurement, the top end of the lower half of the measuring swing rod 6 can simulate the inclination angle of the pre-buried hole 11, and then the conversion of the upper half of the measuring swing rod 6 which is also 120mm long, the offset distance of the upper half is the offset distance of the lower half, and reading the offset of the upper half is to read the offset of the lower half, that is, the inclination of the pre-buried hole 11, when the positioning shaft 3 is positioned, the lower surface of the positioning sleeve 7 also coincides with the rail bearing surface 12, at this time, the positioning sleeve 7 and the positioning cone 2 can be locked into an integrated structure through the locking mechanism, so as to prevent the subsequent position change of the two from causing the positioning shaft 3 to deviate from the set position, thereby ensuring the accuracy of subsequent measurement, and the vernier 5 can accurately measure the accuracy to 0.01mm, further improving the accuracy of measurement.
