[0002] Sleepers are wooden sleepers, which are horizontal wood used to pad under the rails. They are used to support the rails when laying railway tracks. Sleepers are used to keep the gauge of the railway track stable and unchanged. As a material that bears the weight of the rails and passing vehicles, the pressure on the rails and their own weight can be evenly distributed and transferred to the roadbed to keep the railway track stable and unobstructed.

[0003] When sleepers are being processed and used, they need to be tested with a level detector to keep the surface of the sleepers flat during use and prevent them from tilting during installation. When measuring sleepers, the level detector needs to be placed in the middle of the sleepers for testing to make the test more accurate. When placing the level detector to measure sleepers, the operator needs to manually adjust the level detector multiple times, making it difficult to quickly place the level detector in the middle of the sleepers.

[0004] Although there are improved adjustable level detectors in the prior art, they are mainly designed for bridge and road construction, but there is no level detector for rapid adjustment and centering of sleepers. For example, Chinese invention patent No. CN116516778A discloses a level detector, which is suitable for adjusting and measuring bridge decks with different slopes, but not suitable for centering the level detector on sleepers.

[0005] Therefore, it is necessary to study a sleeper leveling detection device to solve the above problems or alleviate the impact of the above problems. Utility Model Content

[0032] The utility model will be further described below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 4As shown, the sleeper leveling detection device of the utility model may include a bubble level 1 and an adjustment seat 2, two ends of the bubble level 1 are respectively fixedly connected to two adjustment seats 2, and each adjustment seat 2 is provided with an adjustment mechanism 4;

[0034] The adjusting mechanism 4 includes a central gear 41 located in the middle of the adjusting seat 2 and two racks 42 respectively meshed with the central gear 41 on both sides in the radial direction. A stopper 5 is provided at one end of the rack 42 away from the central gear 41, and the two racks 42 and the two stoppers 5 corresponding to the two racks 42 are symmetrical about the center of the central gear 41.

[0035] The rotation of the central gear 41 can drive the two racks 42 to move synchronously, and make the two stoppers 5 corresponding to the two racks 42 move closer or farther away synchronously.

[0036] Specifically, the bubble level 1 can judge the levelness of the working surface by observing the position of the bubble in the transparent tube, that is, the bubble level 1 is a measuring component for detecting the flatness of the sleeper 10. The adjustment seat 2 can adjust the position of the bubble level 1 on the sleeper 10 through the adjustment mechanism 4, so that the bubble level 1 can be quickly adjusted to the middle of the sleeper 10 to facilitate detection and improve detection accuracy.

[0037] More specifically, the adjustment mechanism 4 rotates the central gear 41, and the central gear 41 is meshed with the rack 42 through the gear surface, so that the two racks 42 on both sides thereof move synchronously, and then the two stoppers 5 corresponding to the two racks 42 can be synchronously approached. When one of the stoppers 5 is in contact with one side of the sleeper 10, and the other stopper 5 is not in contact with the other side of the sleeper 10, the two stoppers 5 continue to be synchronously approached, so that the bubble level 1 can be moved and adjusted on the sleeper 10, until the two stoppers 5 are respectively stuck on both sides of the sleeper 10, and the positions of the two stoppers 5 are symmetrical about the center of the central gear 41, and at this time the bubble level 1 is in the middle of the sleeper 10.

[0038] In this way, the sleeper leveling detection device can quickly adjust the bubble level 1 to the middle of the sleeper 10 through the adjustment mechanism 4, which can avoid multiple adjustments, reduce operation time, and improve operation efficiency and detection accuracy.

[0039] It should be noted that the bubble level 1 is generally a strip level, and the two adjustment seats 2 are respectively fixedly connected to the two ends of the length direction of the bubble level 1, and the length directions of the two are consistent when the bubble level 1 is placed on the sleeper 10. The middle of the sleeper 10 generally refers to the middle position of the sleeper 10 in the width direction.

[0040] It should also be noted that the adjustment mechanism 4 can be arranged inside the adjustment seat 2 or on the upper surface of the adjustment seat 2. The embodiment of the utility model is described as the adjustment mechanism 4 is arranged inside the adjustment seat 2 and partially visible outside. The central gear 41 is arranged inside the adjustment seat 2 and is located at the center. The central gear 41 can be movably connected to the adjustment seat 2 through the bearing installed at the bottom. Two racks 42 pass through the adjustment seat 2, and the tooth surfaces of the two are meshed with the gear surface of the central gear 41.

[0041] In an example, Figure 4 and Figure 5 As shown, the adjustment mechanism 4 further includes an adjustment bolt 43 passing through the central gear 41, and sliders 45 are provided on both radial sides of the adjustment bolt 43, and the central gear 41 is provided with a slide groove 44 corresponding to and matching with the sliders 45;

[0042] When the adjusting bolt 43 rotates under the action of external force, the slider 45 cooperates with the slide groove 44 to drive the central gear 41 to rotate.

[0043] Specifically, the adjustment bolt 43 passes through the upper end of the adjustment seat 2 and is arranged on the central gear 41. Slide blocks 45 are fixedly connected to the radial sides of the adjustment bolt 43. A slide groove 44 corresponding to the slide block 45 is provided inside the central gear 41 toward the adjustment bolt 43. The adjustment bolt 43 can be circumferentially fixed to the central gear 41 through the cooperation of the slide block 45 and the slide groove 44. In this way, the rotation of the adjustment bolt 43 under the action of external force can drive the central gear 41 to rotate synchronously, so as to provide power for the movement and adjustment of the rack 42 and the limiter 5.

[0044] In an example, Figure 4 and Figure 5 As shown, the cross-section of the slide groove 44 matches the cross-section structure and size of the slider 45 , the vertical dimension of the slide groove 44 is larger than the vertical dimension of the slider 45 , and the slider 45 can slide vertically in the slide groove 44 .

[0045] Specifically, the cross-section of the slide groove 44 matches the cross-section structure and size of the slider 45, that is, the slider 45 can be embedded in the slide groove 44, so that the adjustment bolt 43 is circumferentially fixed to the central gear 41. The vertical dimension of the slide groove 44 is greater than the vertical dimension of the slider 45, that is, the slider 45 can slide vertically in the slide groove 44, thereby enabling the adjustment bolt 43 to move vertically relative to the central gear 41.

[0046] In an example, Figure 4 and Figure 6 As shown, the bottom of the adjusting bolt 43 is fixedly connected to the limiting block 9, and the adjusting seat 2 is provided with a limiting groove 8 corresponding to the limiting block 9, and the limiting block 9 matches the limiting groove 8; the limiting block 9 can pass through the central gear 41 and be inserted into the limiting groove 8, so that the adjusting bolt 43 is circumferentially limited to the adjusting seat 2.

[0047] Specifically, the limit block 9 matches the structure and size of the limit groove 8, and the limit block 9 is embedded in the limit groove 8, so that the adjustment bolt 43 is circumferentially limited to the adjustment seat 2. In this way, when the adjustment bolt 43 needs to drive the central gear 41 to rotate by rotation, the adjustment bolt 43 can be slid upward through the cooperation of the slider 45 and the slide groove 44, so that the limit block 9 moves out of the limit groove 8, thereby releasing the circumferential limitation; when the adjustment bolt 43 does not drive the central gear 41 to rotate, the adjustment bolt 43 can be slid downward through the cooperation of the slider 45 and the slide groove 44, so that the limit block 9 is inserted into the limit groove 8, thereby achieving circumferential limitation.

[0048] Furthermore, the limiting block 9 and the limiting groove 8 are both gear-shaped structures that match each other, and the limiting block 9 and the limiting groove 8 can achieve circumferential limitation.

[0049] In an example, Figure 4 As shown, a limiting elastic member 7 is provided between the adjusting bolt 43 and the adjusting seat 2 , and the limiting elastic member 7 has a pre-tightening force for driving the adjusting bolt 43 to insert the limiting block 9 into the limiting groove 8 .

[0050] Specifically, the limiting elastic member 7 can be a limiting spring, which is sleeved outside the adjusting bolt 43, and the upper end of which is fixedly connected to the bolt head of the adjusting bolt 43, and the lower end can be movably connected to the adjusting seat 2 through a bearing. The adjusting mechanism 4 uses the pre-tightening force of the limiting elastic member 7 to always keep the limiting block 9 inserted into the limiting groove 8 when there is no external force, so that after the bubble level 1 is adjusted, the bubble level 1 is always in the middle of the sleeper 10 when it moves along the length direction of the sleeper 10.

[0051] In an example, Figure 3 As shown, the limiting member 5 is a roller, and its central axis is parallel to the central axis of the central gear 41 .

[0052] Specifically, the stopper 5 is a roller, which is rotatably connected to the lower side of the rack 42, and its wheel surface can roll with the side of the sleeper 10. In this way, when the bubble level 1 moves along the length direction of the sleeper 10, the friction between the stopper 5 and the sleeper 10 can be reduced.

[0053] In an example, Figure 2 As shown, the length direction of the rack 42 is perpendicular to the length direction of the bubble level 1. In this way, when the detection device is adjusted on the sleeper 10, the rack 42 moves along the width direction of the sleeper 10, which can shorten the adjustment distance of the limiter 5 and improve the working efficiency.

[0054] In an example, Figure 2 and Figure 3As shown, the rack 42 is provided with a scale 6 along its length direction, and the scales corresponding to the stoppers 5 on the two racks 42 are the same. The stopper 5 can be set at the position of the zero scale line of the scale 6, so that after the detection device is adjusted on the sleeper 10, the width of the sleeper 10 can be measured intuitively through the scale 6.

[0055] In an example, Figure 1 and Figure 4 As shown, the bottom of the bubble level 1 and the adjustment seat 2 are both provided with a ball 3. In this way, when the detection device is placed on the sleeper 10, the ball 3 fits the upper surface of the sleeper 10, which can reduce the friction between the sleeper 10 and facilitate movement and adjustment.

[0056] In order to better understand the above embodiment, the use process of the sleeper flatness detection device of the present invention is further described below in conjunction with the accompanying drawings.

[0057] When the detection device is used to detect the sleeper 10, the bubble level 1 is placed on the upper side of the sleeper 10, the adjustment bolt 43 is pulled upward, and then the adjustment bolt 43 is rotated, and the slider 45 cooperates with the slide groove 44, so that the adjustment bolt 43 drives the central gear 41 to rotate; when the central gear 41 rotates, the central gear 41 engages with the rack 42, so that the two racks 42 move synchronously; when the two racks 42 approach each other, the two limit members 5 approach the two sides of the sleeper 10; when the bubble level 1 deviates from the middle of the sleeper 10, the detection device moves to the middle of the sleeper 10 under the pressure of the limit member 5, so that the detection device does not need to be adjusted multiple times. And through the ball 3 installed on the detection device and the use of the roller as the limit member 5, the friction of the detection device can be reduced when the detection device is moving and measuring on the sleeper 10, and it is not easy to cause wear to the detection device. In this way, when the detection device measures the sleeper 10 , the operator does not need to adjust the detection device multiple times, and can quickly place the detection device in the middle of the sleeper 10 .

[0058] After the detection device is placed in the middle of the sleeper 10, the adjustment bolt 43 is loosened, and the adjustment bolt 43 moves downward under the action of the limit elastic member 7, so that the limit block 9 and the limit groove 8 are engaged and docked, so that the adjustment bolt 43 is restricted and difficult to rotate, and the rack 42 cannot move. And the edge of the limit member 5 close to the sleeper 10 is aligned with the zero scale line of the scale 6, so that the scale 6 can measure the width of the sleeper 10, and observe whether the widths on both sides of the sleeper 10 are the same, so that the detection device is kept in the middle of the sleeper 10, and when the detection device moves on the sleeper 10 for measurement, the detection device will not deviate from the middle of the sleeper 10.

[0059] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
