Description

TECHNICAL FIELD

[0001] The utility model relates to railway embedded part size detection technical field, and specifically relates to railway embedded part size detection tool. BACKGROUND

[0002] At present, the detection of railway embedded part size mainly relies on manual operation. Manual detection is slow, and the main reasons include the following points:

[0003] Frequent replacement and adjustment of measuring tools: when detecting different size parameters, different measuring tools such as calipers and micrometers need to be replaced and calibrated constantly, which is relatively cumbersome and time-consuming.

[0004] Complexity of multidirectional measurement: in order to comprehensively detect the size of the embedded part, measurement needs to be carried out from multiple angles and directions, and the operation process is complex, which is easy to cause omission or repeated measurement.

[0005] Inaccuracy of manual alignment and positioning: in the measurement process, it is difficult to achieve high precision in manually aligning the positions of the embedded part and the measuring tool, which is easy to introduce measurement error. In order to ensure the accuracy of the measurement result, it is often necessary to repeat the measurement multiple times, which further increases the detection time.

[0006] However, it is worth noting that railway embedded parts usually have relatively single shape and specifications in industrial production. Based on this feature, specific detection tools can be designed to improve detection efficiency. This specific detection tool can be specially optimized for the fixed shape and size of the embedded part, reducing unnecessary operation steps and measurement errors, thereby significantly improving the detection speed and meeting the efficient demand of railway construction for embedded part detection. SUMMARY

[0007] In view of the problems existing in the prior art, the utility model provides a railway embedded part size detection tool.

[0008] In order to solve the above technical problems, the utility model solves them through the following technical schemes:

[0009] The railway embedded part size detection tool comprises a detection box, a detection groove is formed in the side wall of the detection box, a plurality of mounting holes are formed in the inner wall of the detection groove, a negative electrode connector is arranged in the mounting hole, when the railway embedded part is inserted into the detection groove, each part of the railway embedded part is in close contact with the inner wall of the detection groove, the railway embedded part is in contact with the negative electrode connector, the detection box is further provided with a movable positive electrode connector and a display lamp corresponding to the negative electrode connector, and the positive electrode connector and the negative electrode connector form a closed loop, and the corresponding display lamp emits light.

[0010] The railway embedded part is generally made of metal and has good conductivity; when in use, the railway embedded part to be detected is inserted into the detection slot on the side wall of the detection box, and since the size of the detection slot is matched with the embedded part, each part of the railway embedded part can be closely attached to the inner wall of the detection slot. When the railway embedded part is inserted, it will be in contact with the negative electrode connector in the mounting hole. Then the positive electrode connector on the detection box is moved to make it contact with the corresponding part of the embedded part through the detection slot. When the positive electrode connector and the corresponding negative electrode connector form a closed loop, the corresponding display lamp emits light, indicating that the size of the part meets the requirements; if the display lamp does not emit light, it indicates that the size of the part has deviation. Without frequent replacement of measuring tools and multi-directional measurement, only the railway embedded part is inserted and the positive electrode connector is moved, the detection time is greatly shortened; at the same time, the unqualified part of the railway embedded part can be accurately known according to the light and dark of the display lamp.

[0011] As preferred, the side wall of the detection box near the bottom is provided with a support plate, the upper end face of the support plate is fixed with a spring, and the upper end face of the spring is fixed with a sealing plate. Without external force, the sealing plate is closed under the action of the spring to close the detection slot.

[0012] When not detecting, the sealing plate closes the detection slot, which can prevent dust, sundries and the like from entering the detection slot, affecting the accuracy of detection and the service life of the equipment. When detecting, the sealing plate is pressed downward to make the detection slot re-contact with the outside.

[0013] As preferred, the side wall of the detection box is provided with a limiting plate located on both sides of the sealing plate, and the side wall of the sealing plate is attached to the side wall of the limiting plate.

[0014] The limiting plate provides guidance for the movement of the sealing plate, ensures that the sealing plate can move vertically and stably up and down, limits the left and right shaking of the sealing plate, and makes the sealing plate accurately close or open the detection slot, thereby ensuring the normal operation of the equipment.

[0015] As preferred, the bottom wall of the mounting hole is provided with a rubber pad, and the negative electrode connector is fixed on the rubber pad. In a natural state, the negative electrode connector extends out of the slot opening of the detection slot by a distance less than 5mm.

[0016] When the railway embedded part is inserted into the detection slot, it will first contact the extended negative electrode connector. Since the rubber pad has a certain elasticity, it can buffer the impact force of the embedded part on the negative electrode connector, and at the same time make the negative electrode connector fully contact the embedded part, thereby ensuring good electrical connection. The rubber pad plays a buffering role, reduces the direct impact of the embedded part on the negative electrode connector when the embedded part is inserted, and reduces the risk of damage to the negative electrode connector.

[0017] As preferred, a limiting ring is fixed in the mounting hole, and the negative electrode connector extends out of the slot opening of the detection slot through the limiting ring.

[0018] When the railway embedded part is inserted into the detection groove and contacts the negative electrode connector, the limiting ring can limit the movement range of the negative electrode connector, preventing excessive displacement thereof; the negative electrode connector is ensured to work stably at a specified position and will not displace greatly due to external force, thereby ensuring the accuracy and stability of detection.

[0019] As preferred, the display screen is provided on the upper end face of the detection box, and the display lamps are arranged in sequence on the display screen.

[0020] The display lamps are concentrated on the display screen, which facilitates the operator to observe all detection results at the same position, and improves the information acquisition efficiency.

[0021] As preferred, the detection box is provided with a carrying strap on the side wall away from the detection groove.

[0022] The design of the carrying strap makes the detection box easy to carry, and the operator can easily carry it to various positions of the construction site, improving the flexibility of work. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0030] For further understanding of the content of the present application, the present application is described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only used to explain the present application but not to limit the present application.

[0031] ​Example

[0032] like Figures 1-5 As shown, this railway embedded part size inspection tool mainly includes an inspection box 110. An inspection groove 1101 is provided on one side wall of the inspection box 110. The shape of the inspection groove 1101 matches the shape of the railway embedded part. When the railway embedded part is inserted into the inspection groove 1101, all parts of the railway embedded part are in contact with the inner wall of the inspection groove 1101. In this embodiment, three mounting holes 1102 are evenly distributed on the upper inner wall of the inspection groove 1101. In actual inspection, the number of mounting holes 1102 and their positions in the inspection groove 1101 can be reasonably set according to requirements.

[0033] Each mounting hole 1102 is fitted with a negative terminal connector 120, and the bottom wall of the mounting hole 1102 is provided with a rubber pad 170. The negative terminal connector 120 is fixed to the rubber pad 170 and extends through the limiting ring 180 and out of the slot 1101, with an extension distance of less than 5mm. A support plate 1103 is provided on the side wall of the testing box 110 near the bottom. A spring 150 is fixed to the upper surface of the support plate 1103, and a sealing plate 160 is fixed to the upper surface of the spring 150. Limiting plates 1601, which guide the sealing plate 160, are provided on the side walls of the testing box 110 on both sides of the sealing plate 160. A display screen 1401 is provided on the upper surface of the testing box 110, and indicator lights 140, corresponding one-to-one with the negative terminal connectors 120, are arranged sequentially on the display screen 1401. A shoulder strap 190 is provided on the side wall of the testing box 110 away from the testing slot 1101.

[0034] The test box 110 contains a battery. The positive terminal 130 is connected to the battery via a wire 1301, and the negative terminal 120 is also connected to the battery via a wire 1301. The wire 1301 on the negative terminal 120 and the battery are not shown in the accompanying drawings of the instruction manual.

[0035] The operating principle of this railway embedded part dimension inspection tool is as follows:

[0036] When not in use, the sealing plate 160, under the action of the spring 150, closes the detection slot 1101 to prevent dust and debris from entering. When testing is required, the operator presses down on the sealing plate 160 to expose the detection slot 1101. The railway embedded part to be tested is then inserted into the detection slot 1101, and the railway embedded part will contact the protruding negative terminal 120. Next, the operator moves the positive terminal 130 on the detection box 110 so that it contacts the corresponding part of the railway embedded part through the detection slot 1101; since railway embedded parts are generally made of metal, they have good conductivity. When the positive terminal 130 and the corresponding negative terminal 120 form a closed circuit, the corresponding indicator light 140 on the display screen 1401 illuminates, indicating that the size of that part meets the requirements; if the indicator light 140 does not illuminate, it indicates that there is a deviation in the size of that part.

[0037] Through the above setting, the size of the railway embedded part of a specified shape can be detected, the structure is reasonably designed, and the operation is simple. An operator can use it after simple training. Moreover, it is not necessary to frequently change the measuring tool and make multidirectional measurement, which greatly shortens the detection time and improves the work efficiency. Moreover, through the on-off of the multiple display lamps 140, the position of the railway embedded part with unqualified size can be accurately detected, which provides an accurate basis for subsequent processing. The setting of the rubber pad 170 and the limiting ring 180 ensures the stable work of the negative electrode joint 120 and improves the stability and reliability of the detection.

[0038] The sealing plate 160 can close the detection groove 1101 when not detecting, which can prevent foreign matters from entering and ensure the accuracy of detection and the service life of the equipment. The back strap 190 provided on the detection box 110 is convenient to carry and can flexibly adapt to different detection sites.

[0039] In summary, the above is only a preferred embodiment of the present embodiment, and any changes and modifications made within the scope of the patent application of the present embodiment shall be within the scope of the present patent.
