Description

Technical Field

[0001] This utility model relates to the field of rail transit testing equipment technology, and in particular to a rail test vehicle. Background Technology

[0002] With the rapid development of high-speed railways and urban rail transit, higher requirements have been placed on the stability and safety of track structures. As a crucial component of the track structure, surface defects in rails, such as fatigue cracks, rolling edge thickening, and corrugated wear, can impact operational safety and vehicle structure, thus necessitating effective maintenance and repair methods. The vehicle-mounted intelligent rail grinding system, as an automated rail grinding device, integrates intelligent detection, operation control, and grinding systems to achieve intelligent control of the rail grinding process. The intelligent detection system is the core component of the vehicle-mounted intelligent rail grinding system. It obtains data from the intelligent detection system, automatically recommends suitable grinding strategies, and evaluates the effect and provides feedback on the methods after the rail grinding system has finished grinding, thereby achieving automation and intelligence in rail grinding.

[0003] In existing technologies, during the initial functional testing and performance verification of intelligent detection systems, the systems are typically installed on operational vehicles. The intelligent monitoring system performs its detection tasks while the vehicles are performing operational tasks. However, due to the limited operating time of these vehicles, the time available for maintaining the intelligent monitoring system is limited, which may impact the initial functional testing and performance verification of the intelligent detection system.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0051] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0052] Please refer to the following: Figure 1 and Figure 2 This application provides a track test vehicle 1, including a chassis assembly 11, a wheel set 12, a support assembly 13, and a mounting beam 14. The wheel set 12 is rotatably mounted on the chassis assembly 11 and is used to roll on the track. The wheel set 12 includes a first direction (e.g., Figure 1 A first roller 121 and a second roller 122 are spaced apart on the chassis assembly 11 (as shown in the X direction). A support assembly 13 is connected to the chassis assembly 11. A mounting beam 14 has opposing first and second surfaces. The first surface faces the chassis assembly 11, the support assembly 13 is connected to the first surface, and the first surface is used to mount the intelligent detection system 2. The second surface is used to house the control assembly 15, which controls the rolling or stationary movement of the wheels. The first surface has two mounting positions, both for mounting the intelligent detection system 2. These mounting positions are located between the first roller 121 and the second roller 122 in the first direction. The orthographic projection of the chassis assembly 11 onto the first surface is shown in the second direction (as shown in the X direction). Figure 1 (As shown in the Y direction) It is located between two assembly positions, where the first direction and the second direction are perpendicular to each other.

[0053] It is understandable that during the operation of the track test vehicle 1 on the track, the first direction is roughly parallel to the extension direction of the track, and the second direction is roughly perpendicular to the extension direction of the track, that is, roughly parallel to the lateral direction of the track.

[0054] The first surface has two mounting positions for installing the intelligent detection system 2 spaced apart in the second direction. When the track test vehicle 1 runs on the track, the intelligent detection system 2 installed at the two mounting positions will detect the two tracks respectively. The orthographic projection of the chassis assembly 11 on the first surface is located between the two mounting positions in the second direction, which can prevent the chassis assembly 11 from obstructing the detection of the intelligent detection system 2 on the track.

[0055] The track test vehicle 1 provided in this application embodiment is provided with an assembly position for installing the intelligent detection system 2. Installing the intelligent detection system 2 in the assembly position can simulate installing the intelligent detection system 2 in an operating vehicle, thereby replacing the method of installing the intelligent detection system 2 in an operating vehicle to perform preliminary functional testing and performance verification of the intelligent detection system 2.

[0056] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, the chassis assembly 11 includes a fixed chassis 111, a lifting chassis 112, and a lifting assembly 113. The wheel set 12 is rotatably mounted on the fixed chassis 111. The lifting chassis 112 is disposed in a third direction (e.g., on the fixed chassis 111). Figure 3 In the Z-direction (as shown), the support component 13 is connected to the side surface of the lifting chassis 112 opposite to the fixed chassis 111, wherein the third direction is perpendicular to the first direction and perpendicular to the second direction. The lifting component 113 is connected between the fixed chassis 111 and the lifting chassis 112, and the lifting component 113 is used to drive the lifting chassis 112 to move upward in the third direction.

[0057] It is understandable that during the operation of the track test vehicle 1 on the track, the third direction is roughly parallel to the vertical direction.

[0058] It should be noted that since the chassis structures of different types of rail vehicles are not entirely the same, the installation positions of the intelligent detection system 2 may differ, resulting in different detection heights between the intelligent detection system 2 and the track. To simulate this, in this embodiment, the lifting assembly 113 drives the lifting chassis 112 to move upwards in a third direction, allowing the lifting chassis 112 to move closer to or further away from the fixed chassis 111 in a third direction. This allows the height of the mounting beam 14 relative to the track to be adjusted as needed, simulating the different detection heights between the intelligent detection system 2 and the track when the intelligent detection system 2 is installed on different types of rail vehicles, thereby improving the accuracy of functional testing and performance verification.

[0059] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the lifting assembly 113 includes a screw 1131 and a drive member 1132. The screw 1131 is rotatably mounted on the fixed chassis 111, and one end of the screw 1131 is connected to the side surface of the lifting chassis 112 facing the fixed chassis 111. The control assembly 15 is used to control the operation of the drive member 1132, which drives the screw 1131 to rotate around its own rotation axis, so that the screw 1131 moves relative to the fixed chassis 111 in a third direction and drives the lifting chassis 112 to move in the third direction.

[0060] In this embodiment, the driving component 1132 drives the screw 1131 to rotate around its own rotation axis, so that the screw 1131 can move relative to the fixed chassis 111 in a third direction, thereby driving the chassis to move relative to the fixed chassis 111 in a third direction. By rotating the screw 1131 to drive the lifting chassis 112 to move, the height between the lifting chassis 112 and the fixed chassis 111 can be precisely adjusted, thereby accurately simulating the different detection heights between the intelligent detection system 2 and the track when the intelligent detection system 2 is installed on different types of rail vehicles.

[0061] Please continue reading. Figure 5 and Figure 6 In some embodiments, the lifting assembly 113 further includes a housing 1133, a worm gear 1134, and a worm 1135. The housing 1133 is disposed on a fixed chassis 111, and the screw 1131 passes through the housing 1133. The worm gear 1134 is rotatably disposed within the housing 1133, and the housing 1133 restricts the movement of the worm gear 1134 in a third direction. The worm gear 1134 is sleeved on the screw 1131, and the worm gear 1134 and the screw 1131 are connected by a thread, with the rotation axis of the worm gear 1134 coinciding with the rotation axis of the screw 1131. The worm 1135 is rotatably disposed within the housing 1133, and the worm 1135 is connected to the driving member 1132, and the worm 1135 cooperates with the worm gear 1134. The driving member 1132 drives the worm gear 1134 to rotate via the worm 1135, thereby causing the screw 1131 to rotate around its own rotation axis.

[0062] In this embodiment, the worm gear 1134 has opposing outer and inner surfaces in the radial direction. The outer surface engages with the worm 1135, and the inner surface engages with the screw 1131. When the drive member 1132 drives the worm 1135 to rotate, the worm 1135 drives the worm gear 1134 to rotate, and the worm gear 1134 drives the screw 1131 to rotate. Since the housing 1133 restricts the movement of the worm gear 1134 in a third direction, the screw 1131 can move in a third direction while rotating, thereby driving the lifting chassis 112 to move in a third direction.

[0063] Please continue reading. Figure 5 and Figure 6 In some embodiments, the lifting assembly 113 further includes two bearings 1136, both of which are disposed within the housing 1133 and sleeved on the screw 1131. The two bearings 1136 are located on both sides of the worm gear 1134 in the third direction. The shaft rings 1136a of the two bearings 1136 are connected to the worm gear 1134, and the seat rings 1136b of the two bearings 1136 are connected to the housing 1133.

[0064] It should be noted that in this embodiment, the seat ring 1136b and shaft ring 1136a of the two bearings 1136 are arranged vertically, with the rolling elements located between the seat ring 1136b and shaft ring 1136a. Although both bearings 1136 are fitted onto the screw 1131, there is no contact between the bearings 1136 and the screw 1131.

[0065] Two bearings 1136 are located on both sides of the worm gear 1134 in the third direction. The bearing rings 1136a of the two bearings 1136 are connected to the worm gear 1134 and rotate synchronously with the worm gear 1134. The bearing rings 1136b of the two bearings 1136 are connected to the housing 1133 and remain stationary. This allows the housing 1133 to restrict the movement of the worm gear 1134 in the third direction while the worm gear 1134 rotates.

[0066] Please continue reading. Figure 5 and Figure 6 In some embodiments, the lifting assembly 113 further includes a tray 1137, which is connected to the side surface of the lifting chassis 112 facing the fixed chassis 111, and the end of the screw 1131 facing the lifting chassis 112 is rotatably connected to the tray 1137.

[0067] The end of the screw 1131 facing the lifting chassis 112 can rotate relative to the tray 1137, thereby preventing the end of the screw 1131 facing the lifting chassis 112 from directly contacting the lifting chassis 112 and avoiding damage to the lifting chassis 112.

[0068] Please refer to it again. Figure 4 In some embodiments, the number of lifting components 113 is four.

[0069] The four sets of lifting components 113 ensure that the lifting chassis 112 remains approximately parallel to the fixed chassis 111 during the lifting process, preventing the lifting chassis 112 from tilting. In addition, the four sets of lifting components 113 can distribute the weight of the lifting chassis 112, preventing individual lifting components 113 from being damaged due to excessive force.

[0070] Please see Figure 2 In some embodiments, the number of support components 13 is two sets, and the two sets of support components 13 are spaced apart in the second direction.

[0071] In this embodiment, the two sets of support components 13 are spaced apart in the second direction, which can balance the mounting beam 14 in the second direction and prevent the mounting beam 14 from tilting. At the same time, the two sets of support components 13 can distribute the weight of the mounting beam 14 and the two intelligent detection systems 2, avoiding damage to a single support component 13 due to excessive force.

[0072] Please refer to the following: Figure 2 and Figure 7 In some embodiments, the support assembly 13 includes a first support member 131 and a second support member 132, the first support member 131 and the second support member 132 are spaced apart along a first direction, and both the first support member 131 and the second support member 132 are connected between the chassis assembly 11 and the first surface.

[0073] The first support member 131 and the second support member 132 are spaced apart along a first direction, allowing the cable of the intelligent detection system 2 to be routed through the gap between the first support member 131 and the second support member 132 to electrically connect with the control component 15 located between the two sets of support components 13 in a second direction. Simultaneously, the first support member 131 and the second support member 132 can balance the mounting beam 14 in the first direction.

[0074] Please continue reading. Figure 2 and Figure 7 In some embodiments, the first support member 131 includes a first body 1311 and a first connector 1312. The first body 1311 is connected to the chassis assembly 11, and the first connector 1312 is connected between the first body 1311 and a first surface, with the extension direction of the first connector 1312 inclined relative to the first surface. The second support member 132 includes a second body 1321 and a second connector 1322. The second body 1321 is connected to the chassis assembly 11, and the second connector 1322 is connected between the second body 1321 and the first surface, with the extension direction of the second connector 1322 inclined relative to the first surface.

[0075] The extension directions of the first connector 1312 and the second connector 1322 form a triangular structure with the first direction, which can improve the stability of the structure.

[0076] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
