[0030] To realize nondestructive measurement of the length of the oil filling pipe 10 on the product oil tank, the technical scheme provides an oil filling pipe measuring device, which comprises:
[0031] A main ruler 100, which is provided with a plurality of scale lines 110 arranged at intervals along an axis, and is used to be inserted into the oil filling pipe 10;
[0032] A movable claw 200, which is arranged at one end of the main ruler 100 and is rotatably arranged outside the main ruler 100 to rotate to a first position parallel to the main ruler 100 or rotate to a second position abutting against the end of the main ruler 100.
[0033] In the technical scheme of the utility model, the movable claw 200 is rotatably arranged at one end of the main ruler 100 and can rotate between the first position parallel to the main ruler 100 and the second position abutting against the end of the main ruler 100; during measurement, the movable claw 200 can be rotated to the first position, at this time, the main ruler 100 and the movable claw 200 can be inserted into the oil filling pipe 10, after the movable claw 200 passes through the oil filling pipe 10, the movable claw 200 can be adjusted to the second position, at this time, the movable claw 200 can abut against the pipe opening at the bottom of the oil filling pipe 10, then the scale on the main ruler 100 aligned with the pipe opening at the top of the oil filling pipe 10 can be read to determine the size of the oil filling pipe 10, after measurement, the movable claw 200 can be adjusted to the first position again and then be pulled out of the oil filling pipe 10, thus the oil filling pipe 10 does not need to be cut, nondestructive detection of the oil filling pipe 10 is realized, and the cost is reduced.
[0034] For example, Figures 1 to 4In one embodiment of this utility model, the refueling pipe measuring device includes a main scale 100, which is a straight rod. Multiple scale lines 110 are provided on the outer peripheral wall of the main scale 100, spaced apart along the axial direction (i.e., length direction) of the main scale 100. The main scale 100 is used to extend into the refueling pipe 10. The main scale 100 can be of a rigid structure, allowing it to pass through the sealing ring of the mechanical seal valve without bending when inserted into the refueling pipe 10. Furthermore, the radial width of the main scale 100 can be less than or slightly greater than the aperture of the sealing ring to ensure smooth passage. Additionally, the main scale 100... One end of the measuring instrument is equipped with a movable jaw 200, which can rotate relative to the main scale 100. Specifically, the movable jaw 200 is rotatably connected to the end of the main scale 100 via a hinge structure. By rotating, the movable jaw 200 can rotate to be parallel to the main scale 100, at which point the movable jaw 200 can fit against the main scale 100; this is the first position. It can also rotate to abut against the end of the main scale 100 and be perpendicular to it; this is the second position. The function of the movable jaw 200 is to abut against the bottom end of the filler pipe 10 located inside the fuel tank during measurement, ensuring that the position of the main scale 100 is fixed. The measurement process will be explained below:
[0035] Before measurement, the movable jaw 200 needs to be rotated to the first position. At this time, the main scale 100 and the movable jaw 200 are rod-shaped as a whole. Then, the movable jaw 200 is inserted into the filling pipe 10. The movable jaw 200 and the main scale 100 can pass through the sealing ring of the mechanical seal valve and reach the other end of the filling pipe 10 (the end located inside the oil tank). Then, the movable jaw 200 can be operated to open to the second position. The method of operating the movable jaw 200 is not limited. In this solution, the movable jaw 200 can be rotated to the second position by swinging the main scale 100. Alternatively, a pull cable can be set on the outside of the main scale 100 and connected to the movable jaw 200 to pull the movable jaw 200 to the second position. There is no restriction here. After that, the main scale 100 is pulled outward until the movable jaw 200 abuts against the end of the filling pipe 10. Figure 3 As shown, the main scale 100 is fixed in position at this time. By reading the scale on the main scale 100 corresponding to the opening of the refueling pipe 10, the length of the refueling pipe 10 can be determined. After the measurement is completed, the movable jaw 200 can be readjusted to the first position and then pulled out. The above detection process can be completed without damaging the fuel tank or the refueling pipe 10, realizing non-destructive testing of the refueling pipe 10. Moreover, the refueling pipe measuring device is simple to operate and greatly improves the detection speed.
[0036] like Figure 2 and Figure 3In an embodiment of the utility model, the fuel filler pipe measuring device further comprises a traction member 300, the traction member 300 is drivingly connected with the movable claw 200 to drive the movable claw 200 to rotate. The traction member 300 is arranged to facilitate the movable claw 200 to adjust the position, and the structure of the traction member 300 can be various; for example, the traction member 300 can be a pull rod movably arranged in the main ruler 100, one end of the pull rod is hinged with the movable claw 200 after penetrating through the main ruler 100, the movable claw 200 can be driven to rotate by pulling the pull rod, of course, the pull rod can also be made of elastic material, allowing the pull rod to have certain deformation to prevent damage; in the scheme, the traction member is arranged to facilitate the operation of the movable claw 200, which is conducive to reducing the operation difficulty and improving the detection efficiency.
[0037] Figure 1 A structure of a traction member 300 is shown, in the embodiment, the movable claw 200 can be independent of the main ruler 100, and the traction member 300 comprises:
[0038] A first pull wire 310 is slidably arranged in the main ruler 100, one end of the first pull wire 310 is connected with the middle part of the movable claw 200, and the other end of the first pull wire 310 is exposed at the end of the main ruler 100 away from the movable claw 200, and the first pull wire 310 is used to drive the movable claw 200 to rotate from the first position to the second position;
[0039] A second pull wire 320 is slidably arranged outside the main ruler 100, one end of the second pull wire 320 is connected with one end of the movable claw 200, and the second pull wire 320 is used to drive the movable claw 200 to rotate from the second position to the first position.
[0040] The first pull wire 310 and the second pull wire 320 can be made of high-strength materials such as nylon, the main ruler 100 can be designed as a hollow circular tube structure, the first pull wire 310 can be inserted into the main ruler 100 and fixed in the middle of the movable claw 200 by bonding or the like, and the second pull wire 320 is arranged outside the main ruler 100 and connected to one end of the movable claw 200. When it is needed to adjust to the first position, the second pull wire 320 can be pulled, and the movable claw 200 will swing to fit the outer wall of the main ruler 100 under the traction of the second pull wire 320. In addition, the first pull wire 310 can cooperate with the second pull wire 320, and the movable claw 200 can be fixed in position by simultaneously pulling the first pull wire 310 and the second pull wire 320, so that the movable claw 200 can smoothly enter and exit the oil filler pipe 10. When it is needed to adjust to the second position, only the first pull wire 310 needs to be pulled. Since the first pull wire 310 is connected to the middle of the movable claw 200, the middle of the movable claw 200 will abut against the end of the main ruler 100 under the traction of the first pull wire 310, and the movable claw 200 can also maintain a perpendicular state with the main ruler 100. In the above scheme, the position adjustment of the movable claw 200 can be conveniently realized by arranging the first pull wire 310 and the second pull wire 320, and the overall size of the oil filler pipe measuring device can also be reduced because the diameters of the first pull wire 310 and the second pull wire 320 can be large or small.
[0041] As Figure 1 In an embodiment of the present application, one end of the first pull wire 310 away from the movable claw 200 is connected to one end of the second pull wire 320 away from the movable claw 200. In the present scheme, the first pull wire 310 is connected to the second pull wire 320, so that the operator only needs to use one hand to pull the first pull wire 310 and the second pull wire 320 at the same time, and it is more convenient to use one hand to wind or unwind the first pull wire 310 or the second pull wire 320, thereby facilitating the operation.
[0042] In an embodiment of the present application, the first pull wire 310 and / or the second pull wire 320 are respectively detachably connected to the movable claw 200. The detachable connection can be winding around a screw and tightening on the movable claw 200, etc. The detachable connection design can facilitate the assembly of the first pull wire 310 and the second pull wire 320 with the movable claw 200, and also facilitate the replacement of the first pull wire 310, the second pull wire 320 or the movable claw 200 with different lengths in the later period, so as to adapt to oil filler pipes 10 with different sizes. Figure 4One form of detachable connection is shown, the movable claw 200 is provided with a first connecting ring 210 towards the surface of the main ruler 100, and the first pull wire 310 is arranged in the first connecting ring 210; and / or, the movable claw 200 is provided with a second connecting ring 220 towards the surface of the main ruler 100, and the second pull wire 320 is arranged in the second connecting ring 220, the connecting ring can be integrally formed or welded on the movable claw 200, the first pull wire 310 is tied on the first connecting ring 210, and the second pull wire 320 is tied on the second connecting ring 220, so that the connection of the first pull wire 310 and the second pull wire 320 with the movable claw 200 is facilitated, and subsequent disassembly and replacement are also facilitated.
[0043] In an embodiment of the present application, the scale line 110 is configured as a notch provided on the outer peripheral wall of the main ruler 100, so that the scale line 110 is more wear-resistant, and the main ruler 100 has a longer service life.
[0044] As Figures 1 to 4 In an embodiment of the present application, the fuel pipe measuring device further comprises a measuring claw 400, the measuring claw 400 is slidably sleeved on the main ruler 100, and the measuring claw 400 and the movable claw 200 located at the second position are clamped at the axial two ends of the fuel pipe 10. The measuring claw 400 can slide along the axial direction of the main ruler 100, and during measurement, the measuring claw 400 can be sleeved on the main ruler 100 and slid to clamp the fuel pipe 10 together with the movable claw 200, at this time, the end face of the measuring claw 400 can be aligned with the scale on the main ruler 100, so that the value on the main ruler 100 can be read conveniently.
[0045] As Figure 1 In an embodiment of the present application, at least one of the movable claw 200 and the measuring claw 400 is a flat plate structure, so that when the movable claw 200 abuts against the end of the main ruler 100, the movable claw 200 and the main ruler 100 can be perpendicular to each other, thereby ensuring that when the movable claw 200 abuts against the end of the fuel pipe 10, the main ruler 100 and the fuel pipe 10 are parallel to each other, and the measurement accuracy is ensured. Similarly, the measuring claw 400 is designed as a flat plate, so that the position of the measuring claw 400 abutting against the pipe opening of the fuel pipe 10 and the corresponding scale on the main ruler 100 remain aligned, and the reading accuracy is ensured. In an embodiment of the present application, the width of the movable claw 200 is not greater than the radial width of the main ruler 100, so that the movable claw 200 passes through the mechanical seal valve first. Since the width of the movable claw 200 is not greater than the width of the main ruler 100, the movable claw 200 is more easily passed through the mechanical seal valve, and at the same time, it provides guidance for the subsequent passage of the main ruler 100 through the mechanical seal valve, so that the main ruler 100 is more easily passed through.
[0046] The above are only exemplary embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
