[0002] The lateral resistance test of the sleeper is a routine test step for track inspection. The traditional track bed lateral resistance test equipment cannot accurately reflect the actual state of the track bed, and has a complex structure and cumbersome installation, which greatly damages the track bed state and the test data is inaccurate.

When in use, the bottom of a rail is hooked by the hook, and the two ends of the jack are respectively in contact with the end of the sleeper rail and the base plate, and a force sensor is set between the jack and the sleeper. The thrust is applied by the jack, and the magnitude of the thrust applied to the sleeper is detected by the force sensor. At the same time, an electronic displacement meter is used to detect the displacement of the sleeper, thereby achieving the purpose of detecting the lateral resistance of the sleeper.

[0003] However, in actual use, since the end of the force frame and the base plate are both in a suspended state, and a jack is provided on the force frame, this method will cause one end of the base plate to swing downward under the action of gravity, and manual support of the end plate is required. This is not convenient to use, and the manual support method has certain safety hazards. Therefore, the above-mentioned test device still has room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0021] Please refer to Figure 1-5 The present application provides a lateral resistance test device for testing rail sleepers. As a specific embodiment, the device includes two tension frames 12 arranged in parallel and spaced apart and a base plate 11 arranged at the ends of the two tension frames. A hook 13 is provided at the other end of the tension frame 12. A support wheel 125 is also provided in the middle area of ​​at least one tension frame 12, and the rotation centerline of the support wheel 125 is arranged along the spacing direction of the two tension frames.

[0022] Specifically, it should be noted that the method of use of the patent document recorded in this application is basically the same as that of the background art, except that the reference Figure 1 、 Figure 2 A support wheel 125 is provided in the middle area of ​​the tension frame 12. By providing the support wheel 125, when conducting a lateral resistance test on the sleeper, the bottom of the rail is hooked by the hook 13, and then the upper surface of the sleeper being tested is supported by the support wheel 125. Thus, the tension frame 12 can be supported by the support wheel 125, and there is no need to support the base plate 11 by hand, thereby improving the convenience of use and improving the safety of use.

[0023] As a specific implementation, the support wheel 125 can be installed on one tension frame 12. Preferably, the support wheel 125 is provided on the same side of the two tension frames 12. Supporting by two support wheels 125 can improve the stability of the support.

[0024] Further, as a preferred embodiment, refer to Figure 3 、 Figure 4The tension frame 12 is provided with an adjustment component 124, and the adjustment component 124 includes a sliding member 1243 that can be adjusted for displacement along a first direction away from the two tension frames. The support wheel 125 is provided on the sliding member 1243, and the first direction is perpendicular to the rotation centerline of the support wheel 125.

[0025] Specifically, as a preferred embodiment, by providing an adjustment component 124, the position of the sliding member 1243 can be adjusted according to usage conditions to ensure that after the hook 13 is hooked with the bottom of the rail and the support wheel 125 contacts the upper surface of the sleeper being tested, the two tension frames 12 are both in a horizontal state, thereby achieving the effect of being able to adjust the posture of the tension frames 12. When the tension frames remain in a horizontal state, the plate surface of the base plate 11 can remain in a vertical state, parallel to the vertical end face of the sleeper being tested. At this time, the jack 2 can apply a horizontal thrust to the base plate 11 and the end face of the sleeper, thereby ensuring the accuracy of the test.

[0026] Further, as a specific implementation method, refer to Figure 3 、 Figure 4 The adjustment assembly 124 further includes an adjustment frame 1241 , on which a strip hole 1242 is provided, and a sliding member 1243 is in guiding sliding cooperation with the strip hole 1242 .

[0027] Specifically, the adjustment frame 1241 is fixedly connected to the tension frame 12, and a strip hole 1242 is provided on the adjustment frame from the end of the adjustment frame away from the tension frame. The sliding member 1243 is guided and slidably matched with the strip hole. The end of the adjustment frame is detachably fixedly connected to the limiting end plate by a screw. Through this setting method, the position of the sliding member 1243 can be adjusted, and the support wheel 125 is connected to the sliding member 1243, thereby ensuring that the position of the support wheel 125 is adjusted.

[0028] Furthermore, as a specific embodiment, one end of the adjustment frame 1241 away from the tension frame 12 is threadedly connected with an adjustment screw 1244 . The adjustment screw 1244 is arranged along the first direction, and the end of the adjustment screw is in abutment with the sliding member.

[0029] Specifically, the end of the adjusting frame is detachably fixedly connected to the limiting end plate by a screw, and the adjusting screw 1244 is threadedly connected to the limiting end plate. When in use, the adjusting screw 1244 is threadedly connected to the limiting end plate. During detection work, the hook 13 at the end of the tension frame 12 is hooked with the bottom of the track rail, and the support wheel 125 contacts the upper surface of the sleeper. Under the action of the tension frame's own gravity, the sliding part slides in the strip hole so that the end of the adjusting screw 1244 contacts the sliding part 1243 to limit the sliding part. At this time, the adjusting screw can be rotated forward or reversely according to the posture of the tension frame 12, so as to adjust the posture of the tension frame 12 to a horizontal state. In the specific implementation process, a handwheel is fixedly provided at the end of the adjusting screw 1244, and a rotational force is applied to the adjusting screw through the handwheel.

[0030] Further, as a specific embodiment, refer to Figure 6 , wherein the sliding member 1243 is a rectangular member with a square cross-section, and the side length in the positive direction is greater than the width of the strip hole 1242. By turning, the middle area of ​​the rectangular member is turned so that the cross-section of the middle area of ​​the rectangular member is a rectangle with a side length equal to the width of the strip hole 1242. The middle area of ​​the sliding member 1243 can be guided and slidably matched with the strip hole 1242, and can be axially limited with the adjustment frame 1241, and can be along the spacing direction of the two tension frames 12.

[0031] Furthermore, as a specific embodiment, the sliding member 1243 is provided with a support shaft 1245, the end of which extends toward the area between the two tension frames 12, and the support wheel 125 is provided at the end of the support shaft 1245. Specifically, the support shaft 1245 is welded or plug-fitted to the sliding member 1243. Preferably, the sliding member 1243 is provided with a plug-in hole, and the support shaft 1245 is plug-fitted to the plug-in hole.

[0032] Furthermore, as a specific embodiment, the jack 2 is detachably connected to the base plate 11. A flange is provided at the end of the jack 2, and is detachably fixedly connected to the base plate 11 via the flange. By connecting the jack 2 to the base plate 11, it is possible to ensure that the gravity of the end of the tension frame 12 away from the hook 13 is much greater than that of the hook side. Therefore, when the support force is provided by the support wheel 125, the end of the hook 13 will not sink under the action of gravity, thereby preventing the hook 13 from separating from the rail bottom.

[0033] Furthermore, as a specific embodiment, the tension frame 12 includes a first frame 121 and a second frame 122 that are detachably connected. The first frame is provided with a plurality of first through-holes 1210 evenly spaced apart, and the second frame is provided with a plurality of second through-holes 1220 evenly spaced apart. Specifically, through the above arrangement, the connection position of the first frame and the second frame can be adjusted according to actual needs, thereby adjusting the length of the tension frame 12. During use, the locking screw 123 is passed through the second through-hole 1220 and the first through-hole 1210 at the appropriate position, and then the locking nut is tightened at the end to lock the first frame 121 and the second frame 122. In this way, the length of the tension frame 12 can be adjusted to accommodate jacks of different sizes and sleepers of different sizes.

[0034] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
