Description

Technical Field

[0001] This utility model relates to the field of track inspection equipment technology, specifically a track levelness detection device. Background Technology

[0002] Tracks, also known as railway tracks, are used to ensure the safety of trains traveling on them. The levelness of the tracks is usually checked.

[0003] The current testing device includes two levels mounted on a support base plate. The length of the support base plate is equal to the distance between the two rails, so that when the support base plate moves on the rails, the two levels are respectively facing the left and right rails to detect the levelness of the left and right rails.

[0004] However, because the length of the support base plate is consistent with the spacing between the two rails, the support base plate is quite long, making it inconvenient to carry. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a track levelness detection device to solve the technical problem that existing detection devices in the background art have a long support base plate due to the length of the support base plate being consistent with the interval between the two rails, which makes the support base plate inconvenient to carry.

[0006] The present invention provides a track levelness detection device, wherein the track includes two rails spaced apart, the detection device includes a supporting base plate, two supports that extend outward or fold inward along the length direction of the supporting base plate, and two levelness detectors respectively mounted on the two supports, wherein the levelness detectors are used to detect the levelness of the rails;

[0007] Wherein, the length of the supporting base plate is less than the interval between the two rails. When the two supports are extended outward, the sum of the length of the supporting base plate and the length of the two supports is equal to the interval between the two rails, so that the two leveling instruments are respectively facing the two rails.

[0008] Furthermore, the two brackets are rotatably connected to the two ends of the supporting base plate, and the two ends are arranged obliquely opposite to each other.

[0009] Furthermore, the detection device also includes two snap-fit ​​components, which are used to fix the two brackets respectively.

[0010] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​member elastically connected to the bracket, and a pressing member elastically connected to the support base plate;

[0011] The supporting base plate has a hole into which the snap-fit ​​member extends, the pressing member is elastically connected to the hole, and at least a portion of the pressing member is located outside the supporting base plate.

[0012] Furthermore, the support base plate is also provided with two folding cavities, which are respectively used to accommodate the corresponding bracket and the level detector.

[0013] Furthermore, the detection device also includes sliding wheels mounted on the bracket;

[0014] The folded cavity contains a portion of a cavity designed to accommodate the sliding wheel.

[0015] Furthermore, the folding cavity includes a first cavity and a second cavity that are interconnected, one of the first cavity and the second cavity being used to accommodate the bracket and the level detector, and the other being used to accommodate the sliding wheel.

[0016] Furthermore, the detection device also includes a telescopic push rod rotatably connected to the support base plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the rail levelness detection device of this utility model, by setting the length of the support base plate to be less than the interval between the two rails, the length of the support base plate can be reduced. When measuring the levelness of the rails, the two supports are unfolded outward along the length of the support base plate, so that the sum of the length of the two supports and the length of the support base plate is equal to the interval between the two rails. This allows the leveling instrument mounted on the supports to be directly facing the rails for detection. When the detection device needs to be carried, the two supports can be folded inward, so that the supports and the leveling instrument can be folded inside the support base plate. Through this setting, the length of the support base plate is greatly reduced, achieving the effect of easy carrying, while still enabling the detection of the levelness of the two rails.

Detailed Implementation

[0023] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figure 1-3 The image shows a track level detection device according to one embodiment of the present invention. It should be noted that the track includes two steel rails with a gap between them. In actual practice, the two steel rails are a left steel rail and a right steel rail, and there is a certain gap between the left steel rail and the right steel rail.

[0027] To address the issue that in the prior art, the length of the support base plate 100 is consistent with the interval between the two rails, resulting in a long support base plate 100 that is inconvenient to carry, in this embodiment, the detection device includes a support base plate 100, two supports 200 that extend outward or fold inward along the length direction of the support base plate 100, and two level detectors 300 respectively mounted on the two supports 200. The level detectors 300 are used to detect the levelness of the rails.

[0028] The length of the support base plate 100 is less than the distance between the two rails. When the two supports 200 are extended outward, the sum of the length of the support base plate 100 and the length of the two supports 200 is equal to the distance between the two rails, so that the two level detectors 300 are directly facing the two rails respectively.

[0029] In this embodiment, by setting the length of the support base plate 100 to be less than the interval between the two rails, the length of the support base plate 100 can be reduced. When measuring the levelness of the rails, the two supports 200 are extended outward along the length of the support base plate 100, so that the sum of the lengths of the two supports 200 and the support base plate 100 is equal to the interval between the two rails. This allows the leveling instrument 300 mounted on the supports 200 to face the rails directly for detection. When the detection device needs to be carried, the two supports 200 can be folded inward, so that the supports 200 and the leveling instrument 300 can be folded inside the support base plate 100. This configuration greatly reduces the length of the support base plate 100, making it easy to carry, while still enabling the detection of the levelness of the two rails.

[0030] It should be noted that the leveling instrument 300 in this embodiment belongs to conventional prior art in this field and can be used to detect the levelness of rails.

[0031] Please see Figure 1 As shown, in this example, the two brackets 200 are rotatably connected to the two ends of the support base plate 100, and the two ends are obliquely opposite to each other. In order to ensure the stability of the brackets 200 after they are unfolded, the detection device also includes two snap-fit ​​components 400, which are used to fix the two brackets 200 respectively.

[0032] Specifically, the snap-fit ​​assembly 400 includes a snap-fit ​​member 410 elastically connected to the bracket 200 and a pressing member 420 elastically connected to the support base plate 100. The support base plate 100 has a hole 430 into which the snap-fit ​​member 410 extends. The pressing member 420 is elastically connected to the hole 430, and at least a portion of the pressing member 420 is located outside the support base plate 100. That is, when the bracket 200 is in a folded state, the snap-fit ​​member 410 does not extend into the hole. Within 430, the bracket 200 can rotate relative to the support base plate 100. When the bracket 200 is in the unfolded state, the snap fastener 410 will extend into the hole 430 to restrict the rotation of the bracket 200. When it is necessary to change the bracket 200 from the unfolded state to the folded state, the pressing member 420 is pressed to apply pressure to the snap fastener 410, and the bracket 200 is rotated to move the snap fastener 410 away from the hole 430.

[0033] It should be noted that the snap-fit ​​410 can be elastically connected to the bracket 200 via a spring, and similarly, the press 420 can be elastically connected to the hole 430 via a spring.

[0034] In addition, to ensure that the bracket 200 can be folded inside the support base, in some preferred embodiments, the support base plate 100 is also provided with two folding cavities 500, which are respectively used to accommodate the corresponding bracket 200 and level detector 300.

[0035] In addition, to ensure that the support 200 can move on the rail, in this embodiment, the detection device also includes a sliding wheel 600 provided on the support 200. Specifically, a portion of the folding cavity 500 is used to accommodate the sliding wheel 600. The folding cavity 500 includes a first cavity 510 and a second cavity 520 that are interconnected. One of the first cavity 510 and the second cavity 520 is used to accommodate the support 200 and the level detector 300, and the other is used to accommodate the sliding wheel 600.

[0036] In some preferred embodiments, the detection device further includes a telescopic push rod 700 rotatably connected to the support base plate 100. The telescopic push rod 700 can assist the sliding wheel 600 in moving on the rail, and the telescopic push rod 700 has a telescopic function, so that when the telescopic push rod 700 is not in use, it can be shortened and fit against the top surface of the support base plate 100.

[0037] In summary, the track levelness detection device according to an embodiment of this utility model has at least the following advantages compared to existing detection devices:

[0038] In the rail levelness detection device of this utility model, by setting the length of the support base plate 100 to be less than the interval between the two rails, the length of the support base plate 100 can be reduced. When measuring the levelness of the rails, the two supports 200 are unfolded outward along the length direction of the support base plate 100, so that the sum of the length of the two supports 200 and the length of the support base plate 100 is equal to the interval between the two rails. This allows the levelness detector 300 mounted on the supports 200 to face the rails directly for detection. When the detection device needs to be carried, the two supports 200 can be folded inward, so that the supports 200 and the levelness detector 300 can be folded inside the support base plate 100. Through this setting, the length of the support base plate 100 is greatly reduced, achieving the effect of easy carrying, while also enabling the detection of the levelness of the two rails.
