Description

Technical Field

[0001] This utility model relates to the field of railway gauge measurement technology, and in particular to a railway gauge measurement device with a pre-processing structure. Background Technology

[0002] Railway track gauge is a core geometric parameter of railway tracks, and its accuracy directly affects the safety and stability of train operation. During railway construction, daily maintenance, and inspection, track gauge must be periodically checked using track gauge measuring devices to ensure that the track gauge always meets the requirements of standards such as the "Railway Line Maintenance Rules" (e.g., the standard track gauge in my country is 1435mm, with an allowable deviation of ±2mm). Currently, railway track gauge measuring devices on the market are mainly divided into two categories: portable track gauge rulers and mobile track inspection trolleys. Although portable track gauge rulers are easy to operate, they require manual point-by-point measurement, which is inefficient, and the measurement accuracy is easily affected by the operator's reading error and placement posture. Mobile track inspection trolleys, by carrying sensors, achieve continuous dynamic measurement, which significantly improves efficiency and has become the mainstream inspection equipment.

[0003] However, in actual use, existing mobile track gauge measuring devices suffer from problems because railway tracks are exposed to the outdoor environment for a long time, and the surface is prone to the accumulation of dust, gravel, fallen leaves, oil stains and other attachments. When the measuring components such as laser displacement sensors directly measure the track with attached impurities, the impurities will block the laser reflection path of the sensor or change the measurement reference surface, resulting in a deviation of more than ±3mm in the track gauge data, which cannot meet the requirements of high-precision detection.

[0004] To address this, a railway gauge measuring device with a pre-processing structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a railway track gauge measuring device with a pre-processing structure, which can solve the problem that existing mobile track gauge measuring devices, when used in actual use, suffer from the problem that railway tracks are exposed to the outdoor environment for a long time, and the surface is prone to the accumulation of dust, gravel, fallen leaves, oil stains and other attachments. When the measuring components such as laser displacement sensors directly measure the track with attached impurities, the impurities will block the laser reflection path of the sensor or change the measurement reference surface, resulting in a deviation of more than ±3mm in the track gauge data, thus failing to meet the requirements of high-precision detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a railway gauge measuring device with a pre-treatment structure, comprising a mobile vehicle and a track. A control terminal is fixedly installed on the top of the mobile vehicle. U-shaped frames are fixedly installed on both sides of the rear bottom of the mobile vehicle. A traveling wheel is rotatably connected inside the U-shaped frame. A pre-treatment mechanism is provided on the front side of the bottom of the mobile vehicle. The pre-treatment mechanism includes a cleaning component and an adjustment component. The cleaning component includes a cavity shell. The number of cavity shells is set to two and the two are symmetrically arranged. Multiple brush plates are installed on the side of the cavity shell near the track, and suction holes are opened between two adjacent brush plates. The number of suction holes is set to multiple. A vacuum cleaner is fixedly installed on the top of the mobile vehicle. The suction end of the vacuum cleaner is fixedly connected to a conduit. Corrugated branch pipes are fixedly connected to both sides of the bottom end of the conduit and the corrugated branch pipes are fixedly connected to the cavity shell.

[0007] Preferably, the adjustment assembly includes a bidirectional screw, and a transverse groove is provided at the bottom of the moving vehicle body. The bidirectional screw is rotatably mounted inside the transverse groove via a bearing.

[0008] Preferably, both ends of the surface of the bidirectional screw are threaded with threaded sleeves, and the bottom of the threaded sleeve is fixedly connected to a connecting rod, with the bottom end of the connecting rod fixedly connected to the top of the cavity shell.

[0009] Preferably, a drive motor is fixedly installed on the right side of the mobile vehicle body, and the output shaft of the drive motor is fixedly connected to the bidirectional screw 621.

[0010] Preferably, a positioning block is fixedly connected to the side of the cavity shell near the track, and a positioning groove is provided on the side of the brush plate near the positioning block, and the positioning groove is used in conjunction with the positioning block.

[0011] Preferably, the top of the positioning block is provided with a threaded groove, and the top of the brush plate is threaded with a connecting screw, which is used in conjunction with the threaded groove.

[0012] Preferably, the front and rear sides of the inner wall of the transverse groove are provided with limiting grooves, and the front and rear sides of the threaded sleeve are fixedly connected with limiting blocks, which are slidably connected inside the limiting grooves.

[0013] Preferably, a crossbeam is fixedly connected to the bottom of the mobile vehicle body, and laser displacement sensors are fixedly installed at both ends of the crossbeam.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a cleaning component, allows the brush plate to first physically clean large debris and adhering impurities on the track surface. The suction holes between adjacent brush plates can quickly suck the cleaned fine dust into the cavity shell under the negative pressure of the vacuum cleaner, and then guide it into the vacuum cleaner through the corrugated branch pipe and the guide pipe, forming a dual pre-treatment effect of "sweeping + vacuuming", thereby thoroughly removing the attachments on the track surface, preventing them from blocking the reflection path of the laser displacement sensor or changing the measurement reference surface, ensuring that the track gauge measurement deviation is controlled within the allowable range, and meeting the high-precision detection requirements;

[0016] 2. This application, by setting an adjustment component, allows the screw sleeve to move smoothly along the transverse groove under the guidance of the limit block and the limit groove when the drive motor drives the bidirectional screw to rotate. This, in turn, drives the two cavity shells to synchronously and in opposite directions to adjust the distance through the connecting rod. At the same time, the corrugated branch pipe can flexibly extend and retract with the movement of the cavity shell, allowing for flexible adjustment of the position of the cleaning component. This ensures that the cleaning component and the track always maintain the optimal distance, thereby improving the performance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A railway gauge measuring device with a pre-treatment structure includes a mobile vehicle body 1 and a track 2. A control terminal 3 is fixedly installed on the top of the mobile vehicle body 1. U-shaped frames 4 are fixedly installed on both sides of the rear bottom of the mobile vehicle body 1. The interior of the U-shaped frames 4 is rotatably connected to the traveling wheels 5. A pre-treatment mechanism 6 is provided on the front side of the bottom of the mobile vehicle body 1. The pre-treatment mechanism 6 includes a cleaning component 61 and an adjustment component 62. The cleaning component 61 includes a cavity shell 611. The number of cavity shells 611 is set to two and the two are symmetrically arranged. Multiple brush plates 612 are installed on the side of the cavity shell 611 near the track 2, and suction holes 613 are opened between two adjacent brush plates 612. The number of suction holes 613 is set to multiple. A vacuum cleaner 614 is fixedly installed on the top of the mobile vehicle body 1. The suction end of the vacuum cleaner 614 is fixedly connected to a conduit 615. Corrugated branch pipes 616 are fixedly connected to both sides of the bottom end of the conduit 615 and the corrugated branch pipes 616 are fixedly connected to the cavity shell 611.

[0026] In this embodiment: by setting up the cleaning component 61, the cavity housing 611 serves as the mounting base for the cleaning component 61, supporting the brush plate 612 and the suction hole 613, while simultaneously forming a transition channel for dust storage and transportation, providing structural support for the subsequent dust collection process; the brush plate 612 is used to physically clean dust, gravel, fallen leaves, oil stains, and other attachments on the surface of the track 2, removing impurities that may obstruct the laser in advance, thus pre-treating for the dust collection process; under the negative pressure of the vacuum cleaner 614, the suction hole 613 can remove the fine particles cleaned by the brush plate 612. Dust is quickly drawn into the cavity housing 611, preventing dust residue or secondary dust generation; the vacuum cleaner 614 can provide a negative pressure power source to drive the dust to flow along the path of suction hole 613 → cavity housing 611 → corrugated branch pipe 616 → conduit 615, thereby achieving directional collection of impurities; the corrugated branch pipe 616 can flexibly extend and retract with the spacing of the cavity housing 611, thereby ensuring that the dust suction passage remains unobstructed during the adjustment process, avoiding pipe pulling and breakage, enabling thorough removal of adhering substances from the surface of the track 2, and ensuring the measurement accuracy of the laser displacement sensor 15.

[0027] Specifically, such as Figure 4As shown, the adjustment assembly 62 includes a bidirectional screw 621, and a transverse groove 7 is provided at the bottom of the moving body 1. The bidirectional screw 621 is rotatably mounted inside the transverse groove 7 via a bearing.

[0028] Specifically, such as Figure 4 As shown, both ends of the surface of the bidirectional screw 621 are threaded with a screw sleeve 622, and the bottom of the screw sleeve 622 is fixedly connected to a connecting rod 623, and the bottom end of the connecting rod 623 is fixedly connected to the top of the cavity housing 611.

[0029] Specifically, such as Figure 4 As shown, a drive motor 624 is fixedly installed on the right side of the mobile vehicle body 1, and the output shaft of the drive motor 624 is fixedly connected to the bidirectional screw 621.

[0030] In this embodiment: by setting the adjustment component 62, the bidirectional screw 621 is rotatably mounted inside the transverse groove 7 via bearings, which can convert the rotational power of the drive motor 624 into linear motion, thereby providing a transmission basis for spacing adjustment; the transverse groove 7 can provide installation and movement space for the bidirectional screw 621 and the screw sleeve 622, and can also form a preliminary limit on the movement direction of the screw sleeve 622; when the bidirectional screw 621 rotates, the two screw sleeves 622 can move towards or away from each other along the axial direction of the bidirectional screw 621. When the screw sleeves 622 move, they will drive the cavity housing 611 to move together through the connecting rod 623, thereby achieving precise alignment between the cleaning component 61 and the track 2; the drive motor 624 can drive the bidirectional screw 621 to rotate stably, providing continuous power for spacing adjustment without manual operation. Through the cooperation of the above structures, the spacing of the cleaning component 61 can be quickly adjusted, thereby adapting to measurement needs and improving operational flexibility.

[0031] Specifically, such as Figure 5 As shown, a positioning block 8 is fixedly connected to the side of the cavity shell 611 near the track 2, and a positioning groove 9 is provided on the side of the brush plate 612 near the positioning block 8, and the positioning groove 9 is used in conjunction with the positioning block 8.

[0032] Specifically, such as Figure 5 As shown, the top of the positioning block 8 is provided with a threaded groove 10, and the top of the brush plate 612 is threaded with a connecting screw 11, which is used in conjunction with the threaded groove 10.

[0033] In this embodiment: Through the above device, the positioning block 8 can form a concave-convex fit structure with the positioning groove 9 on the surface of the brush plate 612, which can quickly and accurately position the brush plate 612, limit the displacement deviation of the brush plate 612 in the horizontal and vertical directions, avoid the brush plate 612 from shifting and shaking during the cleaning operation of the track 2, and ensure that the contact degree between the brush and the track 2 is consistent, thereby improving the uniformity of impurity cleaning; the connecting screw 11, through the threaded engagement with the threaded groove 10, can firmly lock the brush plate 612 on the surface of the positioning block 8, which can further prevent the brush plate 612 from shifting due to vibration during the movement and distance measurement of the device, thereby improving the stability of the cleaning component 61 during operation. At the same time, the threaded connection method facilitates the operator to replace the brush plate 612 later, thereby improving the ease of use.

[0034] Specifically, such as Figure 2 As shown, limit grooves 12 are provided on the front and rear sides of the inner wall of the transverse groove 7, and limit blocks 13 are fixedly connected to the front and rear sides of the threaded sleeve 622, and the limit blocks 13 are slidably connected inside the limit grooves 12.

[0035] Specifically, such as Figure 2 As shown, a crossbeam 14 is fixedly connected to the bottom of the mobile vehicle body 1, and laser displacement sensors 15 are fixedly installed at both ends of the crossbeam 14.

[0036] In this embodiment: Through the above settings, the sliding cooperation of the limiting groove 12 and the limiting block 13 ensures that the screw sleeve 622 can only move linearly back and forth along the horizontal direction of the transverse groove 7, avoiding the screw sleeve 622 from rotating during transmission, thereby ensuring the stability and accuracy of the screw sleeve 622 when driving the brush plate 612 to adjust its position; the connecting beam 14 can provide a stable installation reference for the laser displacement sensor 15, thereby ensuring that the installation distance of the two laser displacement sensors 15 is fixed and the detection direction is parallel. At the same time, the symmetrical arrangement of the two laser displacement sensors 15 can simultaneously collect the track gauge data on both sides of the track 2. Compared with the single-sided detection method, it effectively improves the efficiency of track gauge measurement and the synchronization of data, further reduces measurement errors, and ensures the accuracy of railway track gauge detection results.

[0037] Working Principle: First, the entire device is placed stably above the track 2 to be tested, ensuring that the wheels 5 inside the U-shaped frame 4 are precisely aligned with both sides of the track 2 to prevent tilting or offset. When the distance between the two tracks 2 needs to be adjusted, an adjustment command is sent through the control terminal 3 to start the drive motor 624. The output shaft of the drive motor 624 drives the bidirectional screw 621 to rotate. When the bidirectional screw 621 rotates, the threaded sleeves 622 connected at both ends of its surface will move in opposite directions along the transverse groove 7. When the sleeves 622 move, they will drive the two symmetrically arranged hollow housings 611 to move synchronously through the connecting rod 623 until the brush plate 612 on the side of the hollow housing 611 closest to the track 2 is precisely aligned with the side of the track 2, thus completing the positioning of the pretreatment mechanism 6. Then, the vacuum cleaner 614 is started. The vacuum cleaner 614 will transmit negative pressure to the corrugated branch pipes 616 on both sides through the conduit 615, thereby causing the multiple suction holes 613 on the hollow housing 611 to generate suction. The mobile vehicle body 1 is controlled to travel at a constant speed along the track 2. During the travel, the brush plates 612 on the cavity shell 611 will make close contact with the surface of the track 2, so that dust, gravel, fallen leaves and oil stains and other impurities on the surface of the track 2 can be mechanically cleaned. The loose impurities generated by the cleaning will be sucked into the cavity shell 611 through the suction holes 613 between the brush plates 612, and then enter the dust collection bin inside the vacuum cleaner 614 through the corrugated branch pipe 616 and the conduit 615, thereby realizing the synchronous collection of impurities and avoiding secondary scattering of impurities after cleaning, which will affect subsequent distance measurement. While cleaning, the laser displacement sensors 15 at both ends of the crossbeam 14 will always maintain a perpendicular detection angle to the side of the track 2. The dual laser displacement sensors 15 can synchronously collect distance data on both sides of the track 2 and transmit the real-time detection signal to the control terminal 3. The control terminal 3 will automatically calculate the actual track gauge value based on the preset crossbeam 14 length parameters and the distance data collected by the dual laser displacement sensors 15.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
