[0002] With the development of technology, rail transportation is becoming more and more frequent. The condition of the track tread directly affects the safety and efficiency of railway operation. As railway mileage increases and operating speed improves, the demand for tread fault detection is becoming more and more urgent. However, the current manual inspection is inefficient and the accuracy depends on experience. Although automated equipment can improve accuracy, its length exceeds 20 meters, making it impossible to enter narrow spaces such as turnout areas and tunnels. Semi-portable equipment also weighs more than 15 kilograms, requiring multiple people to carry it, making deployment inconvenient, inflexible, and difficult to adapt to complex inspection scenarios. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a portable railway track tread detection device, which solves the problems of low manual efficiency and inconvenient deployment and poor flexibility caused by the large size of automated equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable railway track tread detection device, comprising two external units. Each external unit has a clamping plate at its bottom and a slider fixedly installed at the top of the clamping plate. The slider is installed in a groove at the bottom of the external unit. One end of the slider is equipped with a caliper. A quick-release structure is provided on one side of the external unit. The quick-release structure includes a quick-release base. A fixing post and a pressing plate are fixedly connected to the top of the quick-release base. The pressing plate is located at slots on both sides of the fixing post. A return spring is fixedly connected to the slots on both sides of the fixing post. The other end of the return spring is connected to one end of the pressing plate. A limit block is fixedly connected to the top of the pressing plate. A connecting cover is provided at the top of the fixing post. A connecting block is fixedly connected to one end of the connecting cover. A sliding rod is fixedly connected to one end of the connecting block. A caliper is fixedly connected to one side of the sliding rod. A return spring is fixedly connected to the other end of the sliding rod. A housing is fixedly connected to the other end of the return spring. The front end of the sliding rod and the return spring are located in a groove in the housing.

[0005] As a further embodiment of this utility model: both the outer unit and the outer wall of the box are provided with scale strips, and both calipers one and two are located in the grooves opened in the outer unit and the box, with the scale strips located directly above calipers one and two.

[0006] As a further embodiment of this utility model: the limiting block is an inverted L-shaped structure, the connecting cover is a hollow structure, and one end of the limiting block is located in the U-shaped groove opened on the inner wall of the connecting cover.

[0007] As a further embodiment of this utility model: the clamp slides through the bottom of the outdoor unit, and the two outdoor units are symmetrically arranged about the box.

[0008] As a further embodiment of this utility model: the number of clamps is two, and the opposite side has a convex structure.

[0009] As a further embodiment of this utility model: a reset spring is fixedly connected to one side of the slider, and the other end of the reset spring is fixedly connected to the inner wall of the groove of the outer unit.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This portable railway track tread inspection device achieves single-person portability through a quick-release structure. The quick-release structure consists of a quick-release base, a pressing plate, an inverted L-shaped limiting block, a second return spring, and a connecting cover. When disassembling the device, the operator lightly presses the pressing plate, compressing the second return spring and causing the limiting block to detach from the U-shaped groove on the inner wall of the connecting cover. The connection between the external unit and the housing is then unlocked, allowing for quick disassembly. For assembly, simply align the connecting cover with the fixing post of the quick-release base, release the pressing plate, and the second return spring will push the limiting block into the U-shaped groove, securing it firmly. In confined spaces such as turnout areas, the lightweight components can be disassembled, transported to the inspection point, and then quickly reassembled. In restricted operating environments such as tunnels, disassembly and deployment can be completed with one hand, perfectly solving the pain points of traditional large equipment being unable to enter complex areas and the low deployment efficiency of semi-portable equipment.

[0011] 2. This portable railway track tread detection device, through the combination of calipers one and two with a scale strip, and the clamping plate at the bottom of the external unit fitting against the track tread, if there are defects such as wear or dents on the tread, the displacement of the clamping plate will push the top slider to slide in the groove at the bottom of the external unit, thereby causing caliper one to move synchronously; at the same time, by gently pulling the other side of the external unit, the clamping plate on that side will fit tightly against the track tread under the elastic cooperation of the return spring three, causing the slide rod to slide inside the housing, thereby causing caliper two to move synchronously. The displacement distance can be read from the scale strip, realizing the core advantages of intuitiveness, visualization, high precision, and high efficiency of tread wear measurement.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a portable railway track tread inspection device, including two external units 1. A clamping plate 2 slides through the bottom of the external unit 1, and the two external units 1 are symmetrically arranged about the housing 7. Track tread wear, dents, and other faults often occur in key areas on both the wheel flange side and the load-bearing side. The symmetrical structure allows the convex clamping plates 2 of the two external units 1 to respectively conform to the contours of both sides of the tread.

[0015] The bottom of the outdoor unit 1 is equipped with two clamping plates 2, with one side of each plate having a U-shaped structure. The U-shaped structure can precisely engage with the key stress areas of the tread, avoiding the problems of slippage and poor fit of the flat clamping plate 2. In scenarios where the tread contour has subtle changes, such as in switch areas and curved tracks, the arc-shaped contact surface of the U-shaped structure can adapt to the curvature changes of the tread and always maintain a tight fit, while the flat clamping plate 2 may be partially suspended due to the curvature of the tread, ensuring that the test data remains reliable even in complex scenarios.

[0016] A slider 3 is fixedly installed at the top of the clamping plate 2. The slider 3 is installed in a groove at the bottom of the outdoor unit 1. A return spring 5 is fixedly connected to one side of the slider 3, and the other end of the return spring 5 is fixedly connected to the inner wall of the groove in the outdoor unit 1. During testing, the return spring 5 is always in a slightly pre-tightened state. The spring force pushes the slider 3 downward against the clamping plate 2, making the clamping plate 2 fit tightly against the contour of the track tread. After the test is completed, the return spring 5 will release its elastic potential energy and automatically pull the slider 3 back to its initial position, causing the caliper 4 to return to the zero point of the scale synchronously. There is no need to manually adjust the position of the slider 3, and it can be used directly for the next test.

[0017] One end of the slider 3 is equipped with a caliper 4, and one side of the outdoor unit 1 is equipped with a quick-release structure 6. The quick-release structure 6 includes a quick-release base 601. The top of the quick-release base 601 is fixedly connected to a fixing post 606 and a pressing plate 602. The pressing plate 602 is located at the slots on both sides of the fixing post 606. The slots on both sides of the fixing post 606 are fixedly connected to a return spring 604. The other end of the return spring 604 is connected to one end of the pressing plate 602. The top of the pressing plate 602 is fixedly connected to a limit block 603. The limit block 603 has an inverted L-shaped structure. The connecting cover 605 has a hollow structure, and one end of the limit block 603 is located in the U-shaped groove opened on the inner wall of the connecting cover 605. The inverted L-shaped limiting block 603 has two force-bearing surfaces, horizontal and vertical. After being inserted into the U-shaped groove in the connecting cover 605, it can restrict the connecting cover 605 from moving left and right horizontally, and prevent the connecting cover 605 from falling off vertically. The hollow structure of the connecting cover 605 can accurately fit the fixing post 606 of the quick-release base 601, playing a guiding and positioning role. The cooperation between the inverted L-shaped limiting block 603 and the U-shaped groove can further ensure that the connecting cover 605 and the quick-release base 601 are completely aligned.

[0018] A connecting cover 605 is provided at the top of the fixed column 606. A connecting block 8 is fixedly connected to one end of the connecting cover 605. A sliding rod 9 is fixedly connected to one end of the connecting block 8. A caliper 11 is fixedly connected to one side of the sliding rod 9. A return spring 10 is fixedly connected to the other end of the sliding rod 9. A housing 7 is fixedly connected to the other end of the return spring 10. Both the outer walls of the outdoor unit 1 and the housing 7 are provided with scale strips. Calipers 1 and 2 are located in the grooves opened in the outdoor unit 1 and the housing 7, and the scale strips are located directly above calipers 1 and 2. The grooves provide precise guidance for calipers 1 and 2, allowing them to move only in a straight line along the grooves without lateral deviation or tilting. With the scale strips directly above calipers 1 and 2, operators can directly read the scale values ​​by looking vertically downwards without adjusting their viewing angle.

[0019] The front end of the slide bar 9 and the return spring 3 10 are located in the groove opened in the box body 7.

[0020] The working principle of this utility model is as follows: Before use, the device is assembled through the quick-release structure 6. The connecting cover 605, which is fixed to the slide rod 9 and caliper 11, is aligned with the fixing post 606 of the quick-release base 601. After precise fitting with the guidance of the fixing post 606, the pressing plate 602 is released. The return spring 604 releases potential energy to push the pressing plate 602 to reset, which drives the inverted L-shaped limit block 603 to be inserted into the U-shaped groove in the connecting cover 605 to form a firm lock. This can be completed independently by one person. During testing, the convex clamps 2 at the bottom of the two outer units 1 are attached to the track tread. The contour of the clamp 2 is precisely matched with the tread and can closely fit the key stress area. If there are defects such as wear or dents on the tread, the clamp 2 will make a slight displacement as the contour changes. The slider 3 fixed at its top will then slide in the groove at the bottom of the outer unit 1. The return spring 5 on one side of the slider 3 deforms synchronously, and at the same time, it drives the caliper 4 to move along the scale bar of the outer unit 1. Gently pull the other side of the outer unit 1. With the elastic cooperation of the return spring 3 10, the clamp 2 also fits against the tread surface, allowing the slide rod 9 to slide in the groove inside the box 7. The return spring 3 10 deforms, and the caliper 2 11 moves synchronously along the scale strip on the outside of the box 7. The scale strip on the outside of the box 7 is precisely aligned with the caliper 2 11, allowing the operator to directly read the scale value corresponding to the scale strip, quantify the wear depth of the tread surface, and avoid misjudgment by human experience. After the test is completed, the return springs 1 5 and 3 release elastic potential energy synchronously, driving the slider 3 and slide rod 9 back to their initial positions respectively. The caliper 1 4 and caliper 2 11 synchronously reset to zero, preparing for the next test. When moving to narrow scenarios such as switch areas and tunnels, the pressing plate 602 in the quick-release structure 6 is pressed lightly, and the return spring 2 604 is compressed, causing the limit block 603 to disengage from the return groove, allowing the outer unit 1 and the box 7 to be quickly separated. It is compact and can be put into a portable bag for transport. After arrival, the reassembly process can be repeated for rapid deployment.
