The utility model provides a limit detection device is invaded to tram is applicable to the tram that the automobile body width is no longer than 2650mm (for example, the tram PM06700 automobile body of south Beijing Pu Town vehicle Limited company of china, but not limited to this), as shown in figure 5, including upper and lower superpose and be used for transversely detecting the level and invade first ruler 10 and the second ruler 20 of limit distance, first ruler 10 is located the top second ruler 20 is located under first ruler 10, first ruler 10 with second ruler 20's length is the same, is 52 cm. One end of the first ruler 10 and one end of the second ruler 20 are movably hinged into a whole, and in the figure, a hinge point 30 is located at the rightmost end of the first ruler 10 and the second ruler 20.
Fig. 1-fig. 3 are the embodiment of the utility model provides a tensile state's schematic diagram, after stretching to the limit in the picture, first ruler 10 reaches first pull rod 11 the maximum measurement length with second ruler 20 reaches the maximum measurement length of second pull rod 21 is the same, is 100cm, promptly the utility model provides a tram invades limit detection device and draws back actual measurement overall length to be 100 cm.
As shown in fig. 1 and 4, a first fixing rod 12 and a second fixing rod 22 are respectively inserted into free end portions of the first pull rod 11 and the second pull rod 21 in a penetrating manner, and bottom extending ends of the first fixing rod 12 and the second fixing rod 22 are respectively clamped in a rail groove of a tramcar groove rail to play roles in transverse positioning and rapid detection.
Further, the first fixing rod 12 and the second fixing rod 22 are both cylindrical steel pipes with a diameter of 0.5 cm.
Further, the utility model provides a tram invades limit detection device, simple structure, it is convenient to use, and the major structure (include first ruler 10 first pull rod 11 the second ruler 20 reaches second pull rod 21 etc.) all adopts the almag of corrosion resistant to make, and is durable.
As shown in fig. 3-4 and 7, the free end surfaces of the first and second tie rods 11 and 21 are respectively provided with a screw hole, when in use, the length of the extending end of the bottom of the first fixing rod 12 is adjusted to be the same as the depth of the groove-shaped rail, the length of the extending end of the bottom of the second fixing rod 22 is adjusted to be matched and clamped in the groove of the rail, and the first and second fixing rods 12 and 22 are locked and fixed by passing through the screw holes by fastening screws 40.
As shown in fig. 5 and 6, a level bubble 13 is embedded in the upper surface of the first ruler 10 for quick and accurate horizontal correction.
As shown in fig. 1 to 7, a telescopic pull rod 23 is further hinged to one side of the second ruler 20 close to the hinge point 30, and a length scale is engraved on the telescopic pull rod 23 and used for detecting a longitudinal invasion limit distance of an invasion limit object. The telescopic rod 23 is of a segment-shaped inward-contraction structure (such as a fishing rod type or a radio antenna, but not limited thereto), and the telescopic length thereof is 45cm-315cm, that is, the minimum length is 45cm in the contraction state, and the maximum length is 315cm in the extension state. In addition, the fixed end of the telescopic pull rod 23 (namely, the joint with the second ruler 20) is further provided with a 90-degree rotation limiting clamping groove for quick rotation positioning of the telescopic pull rod 23, and meanwhile, the telescopic pull rod can be guaranteed to be stable in a position perpendicular to the second ruler by 90 degrees.
As shown in fig. 2 and 3, a detection compass 31 is fixedly disposed at the hinge point 30, a pointer 32 on the detection compass 31 is fixedly connected with the second ruler 20, and the pointer 32 correspondingly displays a rotation angle with the rotation of the second ruler 20. When the rail tramcar is used, as shown in fig. 8, the second ruler 20 needs to rotate around the hinge joint 30 anticlockwise, when the included angle between the pointer 32 and the longitudinal line is in the range of 0-72 degrees, the distance between the hinge joint 30 and the working edge of the steel rail is larger than 0.8m at the moment, and the angle range in the compass 31 is also displayed as green, which indicates that the tramcar can normally pass through; when the included angle is in the range of 72 degrees to 90 degrees, the distance between the hinge point 30 and the working edge of the steel rail is between 0.7m and 0.8m, the angle range in the compass 31 is also displayed to be yellow, and the tramcar needs to limit speed and pass through and enhance observation; when the included angle is larger than 90 degrees, the distance between the hinge point 30 and the working edge of the steel rail is smaller than 0.7m, the color of the compass 31 is red, the invasion limit of external facilities on the surface is serious, the tramcar cannot pass through the compass, and the tramcar needs to be braked, stopped and waited for obstacle removal. The design principle is as follows:
the display angle of the compass is assumed to be theta, namely theta is the included angle between the first ruler and the second ruler; the shortest distance from the compass hinge to the steel rail is s; the actual measured portion is l after the ruler is pulled open. Since the actual measured portion after the ruler is pulled apart is 1m in total length, it can be obtained that:
namely, it is
Since the actual measured length of the straight edge after pulling away is 1m,
when s is greater than 0.8m, the vehicle can normally pass through the device
When s is more than 0.7m and less than or equal to 0.8m, the vehicle needs to pass through at a limited speed and be observed intensively, and at the moment
When s is less than or equal to 0.7m, the outside facilities are seriously invaded and the tramcar cannot pass through the facilities, and at the moment
90°<θ≤180°。
The utility model provides a tram invades limit detection device, when taking place to invade the limit, can the short-term test and confirm the minimum distance of external object and tram automobile body limit, judge whether take place to invade the limit, mainly divide into the distance measurement of horizontal direction's distance detection and vertical direction. Wherein:
the horizontal direction is mainly through blocking two articulated rulers in the groove of grooved rail track, and insert the corresponding dead lever height-adjusting of establishing through its free end, again around articulated department anticlockwise rotation second ruler, two rulers (or its pull rod) free end and articulated department (compass) three points confirm a plane, level bubble on the first ruler is finely tuned again, in order to reach whole level, finally confirm the shortest distance between articulated point and the rail, at this moment, pin joint (or compass) are equivalent to the "contact" of trying to touch the infringement thing, reachs corresponding angle and shows through the different colours on the compass through the anti-sine relation, can directly perceived, quick judgement infringement limit risk.
The vertical direction is mainly achieved by means of telescopic tie rods to determine the longitudinal height or distance of the intrusion. During the use, rotate flexible pull rod to 90 rotatory spacing draw-in grooves departments produce more obvious "the groove that falls and feel", at this moment, the measurement personnel judge promptly for rotatory arrival position, flexible pull rod with the second ruler is perpendicular mutually in vertical plane, and the redraw the free end of flexible pull rod is to touching and invade the limit thing, reads out the scale registration, and it is convenient to obtain invading the limit height, detects.
To sum up, the utility model provides a tram invades limit detection device has telescopic structure, and portable and structure are exquisite, and is durable, mainly detects the judgement through the limit object distance of invading at horizontal direction and vertical direction, detects the colour region that accurate and accessible compass pointer corresponds, directly perceived, show testing result fast, easy and simple to handle, and the practicality is good.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, the word "comprising" does not exclude the presence of data or steps not listed in a claim.
