DETAILED DESCRIPTION

[0029] The utility model will be further described below in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2As shown, the track detection device of the utility model may include a mobile base 1, a detection unit 2 and an information receiving unit 3, the mobile base 1 is used to walk on the track, the detection unit 2 is installed on the mobile base 1, and the information receiving unit 3 is connected to the mobile base 1 through an adjustment mechanism;

[0031] Among them, the adjustment mechanism includes a fixed seat 4, a telescopic adjustment component and a mounting platform 5 connected in sequence, the fixed seat 4 is installed on the mobile base 1, one end of the telescopic adjustment component is rotated and adjusted on the fixed seat 4, the other end of the telescopic adjustment component is connected to the mounting platform 5, and the information receiving unit 3 is installed on the mounting platform 5.

[0032] Specifically, the detection unit 2 can perform real-time detection and analysis of multiple key parameters of the track through high-precision measurement and monitoring technology. The information receiving unit 3 can receive the detection information of the detection unit 2 and display the detection information on the screen in digital or image form, so that the operator can clearly and intuitively understand the actual state of the track. The fixed seat 4 can be welded and fixed on the mobile base 1, and the information receiving unit 3 can be detachably installed on the mounting table 5. The mobile base 1 serves as the installation base for the detection unit 2 and the information receiving unit 3. The mobile base 1 can carry the detection unit 2 and the information receiving unit 3 to move along the track, so as to realize the continuity detection of the track.

[0033] The telescopic adjustment component of the adjustment mechanism can be telescopically adjusted along its own length direction, and the telescopic adjustment component is rotated and adjusted on the fixed base 4 installed on the mobile base 1, so that the telescopic adjustment component can be adjusted in angle relative to the mobile base 1. In this way, the information receiving unit 3 is connected to the mobile base 1 through the adjustment mechanism, and the distance between the information receiving unit 3 and the mobile base 1 can be adjusted through the telescopic adjustment component, and the angle between the telescopic adjustment component and the mobile base 1 can be adjusted by rotating the telescopic adjustment component relative to the fixed base 4, so that the information receiving unit 3 can be in a suitable position.

[0034] In this way, the track detection device adjusts the position of the information receiving unit 3 through the adjustment mechanism, so that the operator can adjust the information receiving unit 3 to a suitable position according to his / her own height and the slope of the track line, so as to verify the detection information.

[0035] In an example, Figures 1 to 3 As shown, the telescopic adjustment assembly includes a guide column 7, a guide sleeve 6 and a first locking member 8. The guide column 7 is inserted into the guide sleeve 6, and the guide column 7 can be telescopically adjusted axially relative to the guide sleeve 6. The first locking member 8 can limit the length of the guide column 7 telescopic to the guide sleeve 6.

[0036] Specifically, the guide post 7 is a columnar structure, and the guide sleeve 6 is a cylindrical structure. The sizes of the guide post 7 and the guide sleeve 6 match, that is, the outer diameter of the guide post 7 matches the inner diameter of the guide sleeve 6. The guide post 7 can be inserted into the guide sleeve 6 and telescoped in the axial direction to achieve the change in the length of the telescopic adjustment component. The end of the guide post 7 away from the guide sleeve 6 is connected to the mounting platform 5, and the end of the guide sleeve 6 away from the guide post 7 is connected to the fixed seat 4. In this way, as the length of the telescopic adjustment component changes, the distance between the mounting platform 5 and the fixed seat 4 also changes, that is, the distance between the information receiving unit 3 and the mobile base 1 can be adjusted. The first locking member 8 can axially fix the guide post 7 and the guide sleeve 6 so that the length of the telescopic adjustment component is fixed, which is convenient for fixing the information receiving unit 3 and the mobile base 1 at a suitable distance.

[0037] In an example, Figures 1 to 3 As shown, multiple limiting grooves 9 evenly distributed along the axial direction are provided on both sides of the guide column 7, and first through holes 10 penetrating the sleeve wall are provided on both sides of the guide sleeve 6. The first locking piece 8 can pass through the first through hole 10 and be inserted into the limiting groove 9 to form a limitation.

[0038] Specifically, there are multiple groups of limit grooves 9 evenly distributed on the outer wall of the guide column 7 along its axial direction, and the spacing distance between each two adjacent groups of limit grooves 9 is the same; the circumferential position of each group of limit grooves 9 is the same, and each group of limit grooves 9 includes two radially symmetrical limit grooves 9. Two first through holes 10 penetrating the sleeve wall are opened on both sides of the guide sleeve 6. The two first through holes 10 are radially symmetrical, and the circumferential position of the two first through holes 10 is the same as the circumferential position of each group of limit grooves 9. At the same time, the number of the first locking members 8 is two, and each first locking member 8 can pass through the first through hole 10 and be inserted into the limit groove 9 to achieve axial fixation of the guide column 7 and the guide sleeve 6. In this way, the first locking member 8 cooperates with the first through hole 10 and the limit groove 9 to form a telescopic locking mechanism of the telescopic adjustment assembly. After the guide column 7 and the guide sleeve 6 move relative to each other and adjust the length, the first locking member 8 passes through the first through hole 10 and is inserted into the limit grooves 9 at different axial positions, so that the telescopic adjustment assembly can be fixed at different lengths.

[0039] In an example, Figure 1 and Figure 3 As shown, a reset elastic member 11 is provided between the outer wall of the first through hole 10 of the guide sleeve 6 and the first locking member 8 , and the reset elastic member 11 has a pre-tightening force to insert the first locking member 8 into the limiting groove 9 .

[0040] Specifically, the two ends of the reset elastic member 11 are fixedly connected to the guide sleeve 6 and the first locking member 8, respectively. The reset elastic member 11 is provided with a certain pre-tightening force, so that the first locking member 8 remains in a state of passing through the first through hole 10 and inserted into the limiting groove 9. When it is necessary to adjust the length of the telescopic adjustment assembly, an external force is applied to pull the first locking member 8 out of the limiting groove 9, so that the guide column 7 can be moved and adjusted relative to the guide sleeve 6. When the length adjustment of the telescopic adjustment assembly is completed, the external force is removed, so that the first locking member 8 is inserted into the limiting groove 9 under the action of the reset elastic member 11, and the axial fixation of the guide column 7 and the guide sleeve 6 is achieved.

[0041] Furthermore, the first locking member 8 can be a bolt, and the reset elastic member 11 can be a spring. The spring is sleeved outside the screw rod of the bolt, one end of the spring is fixed to the head of the bolt, and the other end is fixed to the outer wall of the guide sleeve 6.

[0042] In an example, Figure 1 and Figure 2 As shown, the fixing seat 4 is in a U-shaped structure, which includes a bottom plate 12 and two symmetrically arranged semicircular blocks 13 on the bottom plate 12 . An adapter seat 14 for hinged connection with the guide sleeve 6 is provided on the bottom plate 12 .

[0043] Specifically, the fixed base 4 includes a bottom plate 12 and two semicircular blocks 13. The bottom plate 12 is fixed on the movable base 1. The two semicircular blocks 13 are arranged on both sides of the bottom plate 12 facing each other to form a U-shaped structure. A transfer seat 14 is arranged between the two semicircular blocks 13 on the bottom plate 12. The transfer seat 14 is rotatably connected to the guide sleeve 6. The central axis of the rotating shaft of the transfer seat 14 passes through the center of the two semicircular blocks 13, so that the guide sleeve 6 can be rotated 180° around the center axis of the semicircular blocks 13.

[0044] In an example, Figure 1 and Figure 2 As shown, the semicircular block 13 is provided with a plurality of second through holes 15 evenly distributed along the circumference, and the second through holes 15 on the two semicircular blocks 13 correspond one to one; the fixed seat 4 passes through the second through hole 15 and the third through hole on the guide sleeve 6 (not shown in the drawings) through the second locking piece 16, so as to limit the angle between the guide sleeve 6 and the movable base 1.

[0045] Specifically, the second through holes 15 on the two semicircular blocks 13 correspond one to one, and the multiple second through holes 15 on each semicircular block 13 are distributed at equal angles, and the size of the angle is the minimum angle that the guide sleeve 6 can adjust each time. The guide sleeve 6 is also provided with a third through hole that can correspond to the position of the second through hole 15, that is, when the guide sleeve 6 rotates a certain angle, the central axis of the third through hole is the same as the second through holes 15 on both sides. When the angle between the guide sleeve 6 and the movable base 1 is adjusted, the second locking member 16 is sequentially passed through the second through hole 15 of the semicircular block 13 on one side, the third through hole of the guide sleeve 6, and the second through hole 15 of the semicircular block 13 on the other side to achieve the angle limitation between the guide sleeve 6 and the movable base 1. The second locking member 16 can also be a bolt.

[0046] In an example, Figure 1 and Figure 4 As shown, two groups of rollers 17 corresponding to the two rails of the track are provided below the mobile base 1, and brushes (not shown in the drawings) are installed on the outer walls of the rollers 17; the brushes can roll on the rails with the rollers 17 to apply rust remover to the rails.

[0047] Specifically, the mobile base 1 can move along the length direction of the track through the roller 17, and the structure and size of the roller 17 match the track. The outer wall of the roller 17 is provided with a brush, and when the roller 17 rolls on the rail, the brush can contact the rail and apply a rust remover to the rail, thereby removing rust from the rail to maintain the rail.

[0048] Furthermore, a connecting seat 18 is welded and fixed at the bottom of the movable base 1 , and the roller 17 is rotatably connected to the connecting seat 18 .

[0049] In an example, Figure 1 , Figure 2 and Figure 4 As shown, anti-rust liquid tanks 19 are provided on both sides of the mobile base 1, and the anti-rust liquid tanks 19 are connected to a conduit 20 penetrating the mobile base 1, and the outlet end of the conduit 20 extends to the brush, and an electric control valve 21 is provided on the conduit 20.

[0050] Specifically, the anti-rust liquid tank 19 can provide the brush with a rust remover through a conduit 20. The inlet end of the conduit 20 is connected to the anti-rust liquid tank 19, and the outlet end thereof is connected to the brush, so that the rust remover can penetrate into the brush. The conduit 20 is provided with an electric control valve 21, which controls the connection of the conduit 20 by opening and closing the valve, so as to control the supply of the rust remover.

[0051] Furthermore, support sleeves 22 are fixedly connected to both sides of the mobile base 1 by screws, and the anti-rust liquid tank 19 is sleeved inside the support sleeves 22 to achieve a stable connection of the anti-rust liquid tank 19 .

[0052] It should be noted that the track inspection device forms a track maintenance unit by arranging an anti-rust liquid tank 19, a conduit 20, an electric control valve 21 and a brush on the mobile base 1, so that the maintenance device and the inspection device are integrated into one, and maintenance is performed while the track is inspected, which can reduce the workload and effectively improve the work efficiency of maintenance.

[0053] In an example, Figure 1 As shown, the mobile base 1 is a hollow structure, the detection unit 2 is installed in the inner cavity of the mobile base 1, and an inspection door 23 is provided at the installation position of the mobile base 1 corresponding to the detection unit 2.

[0054] Specifically, the mobile base 1 is a hollow structure, and a mounting seat 24 is fixedly provided at the inner bottom end of the mobile base 1, and the detection unit 2 is arranged on the mounting seat 24. An inspection door 23 is arranged above the mounting seat 24, and one side of the inspection door 23 is hinged to the mobile base 1 to facilitate the opening and closing of the inspection door 23. Such an arrangement can facilitate the inspection and maintenance of the detection unit 2. It should be noted that the two rails of the corresponding track of the detection device are provided with a detection unit 2, that is, the mounting seats 24 are provided with two and are symmetrically distributed about the vertical center line of the mobile base 1.

[0055] In an example, Figure 1 and Figure 2 As shown, the mounting platform 5 is connected to the telescopic adjustment assembly via a rotating seat 25 , and the rotating seat 25 can rotate and adjust the mounting platform 5 so that the front of the information receiving unit 3 faces different directions.

[0056] Specifically, the lower end of the rotating seat 25 is rotatably connected to the guide column 7 of the telescopic adjustment assembly. When the telescopic adjustment assembly and the mobile base 1 are adjusted in angle, the lower end of the rotating seat 25 and the telescopic adjustment assembly rotate relative to each other so that the mounting platform 5 and the mobile base 1 remain parallel to each other. The upper end of the rotating seat 25 is connected to the bottom of the mounting platform 5, and the rotating seat 25 can drive the mounting platform 5 to rotate in the horizontal plane, so that the information receiving unit 3 located on the mounting platform 5 also rotates accordingly, that is, the azimuth direction of the information receiving unit 3 can be adjusted. In this way, when the operator needs to repeatedly measure a certain section of track to improve the accuracy of the detection data, the operator can adjust the azimuth direction of the information receiving unit 3 according to the moving direction of the detection device, so that the operator can verify the detection information.

[0057] In order to better understand the above embodiments, the use process of the track detection device of the present invention is further described below with reference to the accompanying drawings.

[0058] First, rotate the guide sleeve 6 to adjust the angle between the guide sleeve 6 and the movable base 1. After adjusting to a suitable angle, the angle is fixed by the second locking member 16; pull out the guide column 7 to adjust the total length of the guide column 7 and the guide sleeve 6. After adjusting to a suitable length, the length is fixed by the first locking member 8; rotate the rotating seat 25 to adjust the horizontal angle of the mounting table 5 so that the front of the information receiving unit 3 faces a direction that is convenient for the operator to observe. In this way, the information receiving unit 3 can be adjusted to a suitable position to facilitate efficient and high-quality detection operations. When the track needs to be repeatedly detected, the position of the information receiving unit 3 can be adjusted again in the above manner.

[0059] Secondly, a sufficient amount of rust remover is injected into the rust-proof liquid tank 19, and then the electric control valve 21 is opened. At this time, the rust remover is transmitted to the roller 17 along the conduit 20, and the brush on the roller 17 is impregnated, and then the roller 17 moves on the track, and the brush brushes the rust remover on the rail, thereby performing rust removal and maintenance operations on the track. In this way, the track detection device can open the electric control valve 21 to brush the rust remover on the track when detecting the track, so that the detection and maintenance of the track can be carried out simultaneously.

[0060] Furthermore, when the detection unit 2 fails, the inspection door 23 can be opened, and then the detection unit 2 can be taken out from the mobile base 1 for inspection. After the inspection is completed, the detection unit 2 can be put into the mobile base 1 and installed, and the inspection door 23 can be closed. This can facilitate the inspection and maintenance of the detection unit 2.

[0061] 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.
