[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-3As shown, this embodiment provides a comprehensive detection device for the position of a railway magnet, including: a housing, a fixing component, and a laser ranging component. The housing is adapted to cooperate with the magnet. The fixing component is located at the bottom of the housing and has two clamping plates 21 that can be selectively moved towards or away from each other. The two clamping plates 21 cooperate to clamp the magnet. The laser ranging component is connected to the housing and can be selectively moved along the height direction of the housing. The laser ranging component can also be selectively rotated relative to the housing to change the angle between itself and the height direction of the housing. It should be noted that the magnet is a wheel position sensor, suitable for detecting the passage of train wheels, axle counting, speed measurement, and wheel position information through electromagnetic induction.

[0026] In some embodiments, the fixing assembly is installed at the bottom of the housing. The fixing assembly has two movable clamps 21, which can be selectively moved toward or away from each other. When the two clamps 21 move toward each other, they cooperate to clamp the magnet, thereby firmly fixing the housing to the railway and ensuring the stability of the detection device during the detection process. The laser ranging assembly is connected to the housing. On the one hand, the laser ranging assembly can move along the height direction of the housing; on the other hand, the laser ranging assembly can rotate relative to the housing, thereby changing the angle between the laser ranging assembly and the height direction of the housing.

[0027] Understandably, when using the detection device of this application, the outer casing is first placed on top of the magnet, and then the two clamping plates 21 are controlled to move toward each other so that the two clamping plates 21 cooperate to clamp the magnet. Then, the laser ranging component is rotated so that the laser emitted by the laser ranging component hits one side of the adjacent magnet (the adjacent magnet is away from the edge of the magnet that cooperates with the detection device). Then, based on the distance of the laser line segment emitted by the laser detection component and hitting the adjacent magnet and the laser emission angle, the distance between the two adjacent magnets can be obtained.

[0028] It is worth mentioning that, since the outer shell is fixed to the magnet by two clamps 21, the plane of symmetry of the outer shell in the width direction of the magnet and the plane of symmetry of the magnet in its own width direction are on the same plane. The detection device is equipped with a microcomputer, which can calculate the horizontal distance between the laser emitting end of the laser ranging component and the axis of the outer shell based on the rotation angle of the laser ranging component relative to the outer shell. Therefore, based on the laser distance emitted to another adjacent magnet, the laser emission angle, and the horizontal distance between the laser emitting end and the axis of the outer shell, the distance between the two adjacent magnets can be obtained.

[0029] In other embodiments, by controlling the laser ranging component to move along the height direction of the housing and abut against the top of the rail, and then controlling the laser ranging component to be in a horizontal state, the laser emitted by the laser ranging component can hit the inner side of the rail. Therefore, based on the laser emission distance and the horizontal distance between the laser emission end and the housing axis, the distance between the magnet and the inner side of the rail can be obtained. It is worth mentioning that the top of the magnet is provided with a protrusion. When the housing is placed on top of the magnet, the outer peripheral wall of the housing is adapted to abut against the protrusion, thereby achieving the positioning of the detection device during installation. After the detection device is positioned, it is suitable for detecting the distance between the magnet and the inner side of the rail.

[0030] In some other embodiments, a displacement sensor is provided inside the housing. The displacement sensor is suitable for detecting the movement distance of the laser ranging component relative to the housing. A microcomputer is communicatively connected to the displacement sensor. Thus, the microcomputer can calculate the distance between the magnet and the top surface of the rail based on the detection value of the displacement sensor and the initial position of the laser ranging component. Specifically, after the detection device is fixed to the magnet, the laser ranging component is moved and stops against the top surface of the rail. At this time, the movement distance of the laser ranging component can be detected by the displacement sensor and transmitted to the microcomputer. Based on the movement distance of the laser ranging component sent by the displacement sensor and the initial position of the laser ranging component (the distance between the laser ranging component and the bottom of the housing is determined when the initial position of the laser ranging component is determined), the microcomputer can calculate the distance between the magnet and the top surface of the rail.

[0031] According to this utility model, the railway magnet position integrated detection device achieves a stable and rapid connection between the detection device and the magnet through the setting of the fixing component, which improves the fixing efficiency of the detection device and ensures the stability of the detection device during detection. At the same time, through the rotation and movement connection between the laser ranging component and the outer shell component, it realizes the rapid and accurate detection of various distance parameters of the railway, thereby improving the detection efficiency and accuracy of the railway.

[0032] It is worth mentioning that the microcomputer can store various distance parameters of the detected railway, thereby realizing the digital and traceable management of maintenance information; of course, the microcomputer is also connected to the control terminal, and the microcomputer can transmit data to the control terminal for storage in real time.

[0033] According to some embodiments of the present invention, the laser ranging component includes a connecting plate 31, which is movably disposed inside the housing and is adapted to move along the height direction of the housing. A laser head 32 is rotatably connected to one end of the connecting plate 31.

[0034] In some embodiments, the connecting plate 31 is movably disposed within the housing, thereby allowing a guide mechanism suitable for cooperating with the connecting plate 31 to be disposed within the housing, thus making full use of the internal space of the housing, thereby making the structure of the detection device more compact and reducing the volume of the detection device.

[0035] Preferably, the housing is provided with a receiving cavity extending in the height direction, and the cross section of the connecting plate 31 corresponds to the cross section of the receiving cavity. Thus, the inner peripheral wall of the receiving cavity can restrict the outer peripheral wall of the connecting plate 31, so that the connecting plate 31 can move stably along the extension direction of the receiving cavity, thereby enabling the laser ranging component to move stably along the height direction of the housing.

[0036] Of course, the connecting plate 31 is suitable for providing a mounting platform for other electrical components of the detection device.

[0037] According to some embodiments of the present invention, one end of the connecting plate 31 is provided with a connecting part 311, the connecting part 311 is located outside the outer shell and a first rotating part is provided at the bottom, the laser head 32 is provided with a second rotating part that rotates with the first rotating part, and a gyroscope is provided inside the laser head 32.

[0038] In some embodiments, the bottom of the connecting part 311 is provided with a first rotating part, and the laser head 32 is provided with a second rotating part. The first rotating part and the second rotating part are rotatably engaged, thereby realizing the rotation of the laser head 32 relative to the outer shell.

[0039] It should be noted that the gyroscope is connected to the microcomputer. When the laser head 32 rotates or tilts, the rotating component inside the gyroscope (such as a high-speed rotating rotor) will maintain its original motion state. By detecting the relative position change of the rotating component with respect to the outer shell, the gyroscope can accurately measure parameters such as the rotation angle and angular velocity of the laser head 32, and output this information to the microcomputer in the form of electrical signals.

[0040] It is worth mentioning that the connection part 311 can prevent the laser head 32 from protruding out of the outer shell. In the event of an accidental collision between the detection device and other objects, the connection part 311 can prevent the laser head 32 from colliding with other objects under certain circumstances. Thus, the connection part 311 can also provide protection for the laser head 32.

[0041] Of course, the connecting plate 31 can also restrict the rotation of the laser head 32. Specifically, the first rotating part is provided at the bottom of the connecting part 311. When the laser head 32 rotates to a horizontal position, the laser head 32 stops against the bottom of the connecting part 311. Thus, the laser head 32 can be easily adjusted to a horizontal position, thereby facilitating the use of the detection device.

[0042] According to some embodiments of the present invention, one of the first rotating part and the second rotating part is a rotating hole, and the other of the first rotating part and the second rotating part is a rotating rod, which is rotatably disposed in the rotating hole.

[0043] In some embodiments, the first rotating part is constructed as a rotating hole. In this case, the bottom of the connecting part 311 is provided with a connecting ear, the connecting ear is provided with a rotating hole, and the laser head 32 is provided with a rotating rod, which is rotatably disposed in the rotating hole. In other embodiments, the first rotating part is constructed as a rotating rod. In this case, the bottom of the connecting part 311 is provided with a connecting ear, the connecting ear is provided with a rotating rod, and the laser head 32 is provided with a rotating hole. The laser head 32 is sleeved on the rotating rod through the rotating hole.

[0044] It is worth mentioning that a damping element is provided between the outer peripheral wall of the rotating rod and the inner peripheral wall of the rotating hole. Thus, when the laser head 32 rotates to any angle, the damping element can fix the relative rotation position of the laser head 32, making the detection device more convenient to use.

[0045] According to some embodiments of the present invention, a locking nut 312 is provided at the other end of the connecting plate 31. The locking nut 312 is located outside the outer shell, and the locking nut 312 can be rotated to selectively abut against the outer shell.

[0046] In some embodiments, when the locking nut 312 is turned clockwise, the nut moves towards the outer casing until it comes into close contact with the outer casing surface. At this point, due to the friction between the nut and the outer casing and the constraint force exerted by the nut on the connecting plate 31, the connecting plate 31 is fixed in its current position and can no longer move along the height direction of the outer casing, thus locking the position of the connecting plate 31. Conversely, when the locking nut 312 is turned counterclockwise, the nut moves away from the outer casing, gradually loosening its contact with the outer casing. The constraint on the connecting plate 31 is released, allowing it to move freely along the height direction within the outer casing, thus releasing the position of the connecting plate 31.

[0047] Therefore, by setting the locking nut 312, operators can quickly and easily adjust the height position of the connecting plate 31 without having complicated operating skills or undergoing long-term training, which improves the ease of use of the detection device and thus improves the efficiency of the detection work.

[0048] According to some embodiments of the present invention, the outer casing is provided with two sliding grooves 111 extending in the height direction. The two sliding grooves 111 are opposite to each other and are respectively adapted to communicate the inside of the outer casing with the outside. One sliding groove 111 is slidably engaged with the connecting part 311, and the other sliding groove 111 is slidably engaged with the locking nut 312.

[0049] Understandably, the inner peripheral wall of one of the slide grooves 111 can restrict part of the outer peripheral wall of the connecting part 311, and the inner peripheral wall of the other slide groove 111 can restrict part of the outer peripheral wall of the locking nut 312, so that the connecting plate 31 can move stably along the extension direction of the slide groove 111, thereby allowing the laser ranging component to move stably along the height direction of the housing.

[0050] According to some embodiments of the present invention, the fixing assembly further includes an adjusting rod 22, which is rotatably disposed inside the housing. The outer peripheral wall of the adjusting rod 22 is provided with a first thread and a second thread spaced apart in the axial direction. The first thread and the second thread have opposite directions of rotation. Both clamping plates 21 are provided with mating holes. The inner peripheral wall of one of the mating holes is provided with a third thread that mates with the first thread, and the inner peripheral wall of the other mating hole is provided with a fourth thread that mates with the second thread.

[0051] In some embodiments, the two clamping plates 21 are respectively a first clamping plate 21 and a second clamping plate 21. The first clamping plate 21 and the second clamping plate 21 are respectively provided with a first mating hole and a second mating hole. The first clamping plate 21 is sleeved on the adjusting rod 22 through the first mating hole, and the second clamping plate 21 is sleeved on the adjusting rod 22 through the second mating hole. The inner peripheral wall of the first mating hole is provided with a third thread, and the inner peripheral wall of the second mating hole is provided with a fourth thread.

[0052] Therefore, when the adjusting rod 22 rotates, it can drive the first clamping plate 21 and the second clamping plate 21 to move towards or away from each other simultaneously, thus facilitating the fixing of the detection device to the magnet. Simultaneously, this arrangement also ensures that the symmetrical plane of the outer casing in the width direction of the magnet is on the same plane as the symmetrical plane of the magnet in its own width direction, avoiding the operator spending excessive time adjusting the position of the detection device.

[0053] In other embodiments, the clamping plate 21 includes a first split part and a second split part, which are rotatably connected. The first split part is provided with a mating hole, and the second split part is adapted to mate with a magnet. Thus, by setting the clamping plate 21 to have a first split part and a second split part that can rotate relative to each other, the height of the detection device can be reduced by rotating the second split part when the detection device is not in use, thereby facilitating the storage and transportation of the detection device.

[0054] In some embodiments, one end of the adjusting rod 22 extends outside the housing and is connected to a rotating block 221, so that the operator only needs to rotate the rotating block 221 to rotate the adjusting rod 22.

[0055] According to some embodiments of the present invention, the outer shell includes a first shell 11 and a second shell 12. The first shell 11 is connected to the laser ranging component, and the second shell 12 is connected to the fixing component. The first shell 11 and the second shell 12 are rotatably connected.

[0056] In some embodiments, the laying direction of the plurality of magnets is parallel to the extension direction of the track, the extension direction of the magnets is parallel to the width direction of the track, and the extension direction of the rail is parallel to the extension direction of the track. Therefore, by rotatably connecting the first housing 11 and the second housing 12, the operator can switch the detection device between detecting the distance between magnets and detecting the distance between magnets and rails by rotating the first housing 11 relative to the second housing 12. This avoids the operator disassembling and readjusting the position of the detection device, further improving its ease of use.

[0057] According to some embodiments of the present invention, the inner peripheral wall of the second housing 12 is provided with a first limiting block 121 and a second limiting block 122, and the inner peripheral wall of the first housing 11 is provided with a limiting rod 112. The limiting rod 112 can selectively abut against the first limiting block 121 or the second limiting block 122 in the circumferential direction. When the limiting rod 112 abuts against the first limiting block 121, the line connecting the limiting rod 112 and the axis of the first housing 11 is the first connecting line. When the limiting rod 112 abuts against the second limiting block 122, the line connecting the limiting rod 112 and the axis of the first housing 11 is the second connecting line. The included angle between the first connection and the second connection is 90° projected in the height direction of the first housing.

[0058] In some embodiments, the first housing 11 rotates relative to the second housing 12 and has a first position and a second position. When the limiting rod 112 abuts against the first limiting block 121, the first housing 11 is in the first position. At this time, the detection device can be used to detect the distance between the magnets. When the limiting rod 112 abuts against the second limiting block 122, the first housing 11 is in the second position. At this time, the detection device can be used to detect the distance between the magnet and the rail.

[0059] Therefore, by setting the first limiting block 121 and the second limiting block 122, the operator only needs to rotate the first housing 11 to switch the function of the detection device, avoiding the operator spending a lot of time adjusting the rotation angle of the first housing 11, and further improving the construction convenience of the detection device.

[0060] According to some embodiments of the present invention, a magnet is provided at the bottom of the outer casing.

[0061] Understandably, a magnet is provided at the bottom of the outer casing, which can be pre-fixed to the magnet, facilitating the fixation of the detection device and the magnet. At the same time, the magnet can further ensure the stability of the fixation between the detection device and the magnet, thereby further ensuring the stability of the detection device during operation.

Various modifications and variations can be made to this utility model by those skilled in the art.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
