Description

Technical Field

[0001] This application relates to the technical field of wheel hub positioning, and in particular to a target for wheel hub positioning of intelligent rail transit. Background Technology

[0002] In the current precise axle positioning process for multi-unit intelligent rail transit vehicles, hub compensation is a crucial step before measurement, and its importance is self-evident. In traditional methods, the target clamp is directly fixed to the wheel hub, relying on the hub edge as a reference for positioning. However, this method is highly susceptible to unforeseen factors such as minute errors during clamping and potential deformation of the hub itself, significantly reducing the accuracy of steering angle and hinge angle measurements and hindering the overall performance evaluation and adjustment of the intelligent rail transit vehicle.

[0003] Utility model patent publication number CN202382945U discloses a target for an automotive four-wheel alignment instrument. The target includes a frame surrounding the target body and a back plate on the lower end face of the target body. A target positioning component is located within the frame, and the target body also has support rod connecting slots for fixing support rods. Fixing the target via support rods requires controlling the installation angle during installation, leading to cumbersome operation, inefficiency, and reduced efficiency of the alignment process. Summary of the Invention

[0004] The purpose of this application is to provide a target for positioning the wheel hub of a smart rail transit system, in order to solve the problem that the positioning process efficiency is reduced because the target needs to be installed at a controlled angle during the installation process.

[0005] The intelligent rail transit vehicle wheel hub positioning target provided in this application adopts the following technical solution:

[0006] A target for intelligent rail transit hub positioning includes:

[0007] The target body is used for positioning by measuring equipment;

[0008] The mounting components include a support frame and a connecting rod. The support frame is located on the back of the target body, and the connecting rod is connected to the support frame. The connecting rod is used to connect to the hub to be positioned and can rotate relative to the support frame.

[0009] The counterweight assembly is located on the back of the target body near the edge and is used to automatically adjust the orientation angle of the target body.

[0010] By adopting the above technical solution, the connecting rod is connected at the center of the wheel hub to be tested, thereby mounting the target on the hub. Since the connecting rod can rotate relative to the support frame, the target body connected to the support frame can also rotate freely relative to the connecting rod. Under the gravity of the counterweight assembly, the counterweight assembly is always below the connecting rod, ensuring that the target body remains at the specified installation angle under the action of the counterweight assembly. This eliminates the need to adjust the installation angle of the target body during installation, and the installation angle is maintained constant even after the hub rotates, allowing for a fast and accurate positioning process.

[0011] Optionally, the front of the target body is provided with multiple positioning holes.

[0012] By adopting the above technical solution, the measuring equipment can use multiple positioning holes on the target body for precise positioning, thereby improving positioning accuracy and efficiency.

[0013] Optionally, the edge of the target body is provided with a protective sleeve.

[0014] By adopting the above technical solution, the protective sleeve effectively enhances the wear resistance and impact resistance of the target body's edge, and extends the service life of the target body.

[0015] Optionally, the counterweight assembly includes a counterweight cover, counterweight bolts, washers, and counterweight blocks. The counterweight bolts are connected to the target body, and the counterweight bolts pass through the washers, counterweight blocks, and counterweight cover in sequence to fix the washers, counterweight blocks, and counterweight cover to the back of the target body.

[0016] By adopting the above technical solution, the counterweight bolts are used to fix the breeding components, and the gaskets can form a buffer between the counterweight block and the target body to avoid mutual wear between the two. The counterweight block is used to provide gravity, while the counterweight cover surrounds the former two to prevent the external environment from causing wear and damage to the gaskets and counterweight block.

[0017] Optionally, the connecting rod is tilted relative to the target body so that the target body and the hub form an installation angle after installation.

[0018] By adopting the above technical solution, since the intelligent rail transit vehicle has many wheels, the installation angle formed between the target body and the wheel hub allows the measuring equipment to detect multiple targets simultaneously, which helps to improve positioning efficiency.

[0019] Optionally, the support frame has connection holes on its side wall and the target body has mounting holes. The connection holes and mounting holes are provided in correspondence for connecting the support frame and the target body.

[0020] By adopting the above technical solution, the connection between the support frame and the target body is more stable and reliable, and it is easy to assemble and disassemble quickly, thus improving the overall ease of use of the positioning target.

[0021] Optionally, a rubber plug is provided on the side wall of the support frame, which contacts the connecting rod to generate rotational damping in the connecting rod.

[0022] By adopting the above technical solution, the connecting rod has a certain damping effect during rotation, which effectively prevents the target body from rotating due to slight external force during positioning, ensuring the accuracy of positioning, and preventing the target body from rotating too fast, thus avoiding impact on internal components.

[0023] Optionally, two connecting bearings are provided between the connecting rod and the support frame.

[0024] By adopting the above technical solution, the two connecting bearings effectively improve the stability and smoothness of the connecting rod's rotation relative to the support frame, thereby improving the overall positioning accuracy and service life of the target.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Because the connecting rod can rotate relative to the support frame, the target body connected to the support frame can rotate freely relative to the connecting rod. Under the gravity of the matching component, the counterweight component is always below the connecting rod, thus ensuring that the target body remains at the specified installation angle under the action of the counterweight component. This eliminates the need to adjust the installation angle of the target body during installation, and the installation angle remains constant even after the hub rotates, allowing for a fast and accurate positioning process.

[0027] 2. The counterweight bolts are used to secure the mating assembly, and the gaskets create a buffer between the counterweight and the target body, preventing mutual wear. The counterweight provides gravity, while the counterweight cover surrounds both, preventing external environmental damage to the gaskets and counterweight.

[0028] 3. The connecting rod has a certain damping effect during rotation, which effectively prevents the target body from rotating due to slight external force during positioning, ensuring the accuracy of positioning, and preventing the target body from rotating too fast, thus avoiding affecting the internal components.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] A target for intelligent rail transit hub positioning, referring to Figure 1 and 2 The system includes a target body 1, a mounting assembly 2, and a counterweight assembly. Both the mounting assembly 2 and the counterweight assembly are mounted on the back of the target body 1. The target body 1 is used for positioning by measuring equipment. The front of the target body 1 has multiple neatly arranged positioning holes 11. Precise positioning with the measuring equipment through these holes 11 improves the accuracy and efficiency of the positioning process. The edges of the target body 1 are also equipped with protective sleeves 12, which effectively enhance the wear resistance and impact resistance of the target body 1's edges, extending its service life.

[0035] Reference Figure 3 The mounting component 2 includes a support frame 21 and a connecting rod 22. The support frame 21 is located on the back of the target body 1 and has a connecting hole 23. The back of the target body 1 has a mounting hole 13 corresponding to the connecting hole 23. The connecting hole 23 and the mounting hole 13 make the connection between the support frame 21 and the target body 1 more stable and reliable, and facilitate quick assembly and disassembly, improving the overall ease of use of the positioning target. The connecting rod 22 connects to the support frame 21 and is used to connect to the wheel hub to be positioned. The connecting rod 22 can rotate relative to the support frame 21, so that the target body 1 can rotate relative to the wheel hub to be positioned. The support frame 21 is inclined on the back of the target body 1, so that the connecting rod 22 is also inclined relative to the target body 1. Since the intelligent rail transit vehicle has many wheels, by forming an installation angle between the target body and the wheel hub, the measuring equipment can simultaneously detect multiple targets, which is beneficial to improving positioning efficiency. Two connecting bearings 25 are provided between the support frame 21 and the connecting rod 22. The two connecting bearings 25 are respectively located on both sides of the part of the connecting rod 22 located inside the support frame 21, so that the support frame 21 and the connecting rod 22 can be stably connected and the rotation stability can be guaranteed.

[0036] Reference Figure 2The counterweight assembly is located on the back of the target body 1 near the edge. Because of its proximity to the edge, the counterweight assembly will remain below the mounting assembly 2 under gravity when no external force is applied, thus controlling the angle of the target body 1. This allows the target to automatically adjust its angle after installation, and also automatically adjusts its angle when the hub rotates, ensuring that the target body 1 faces the measuring equipment, enabling a fast and accurate positioning process. The counterweight assembly includes a counterweight cover 33, a counterweight bolt 32, a washer 34, and a counterweight block 31. The counterweight bolt 32 connects to the back of the target body 1, the washer 34 is located on the surface of the target body, and the counterweight block 31 is located on the surface of the washer 34. The counterweight cover 33 surrounds the counterweight block 31 and the washer 34 from the outside, and the counterweight bolt 32 passes through all three, fixing them to the target body 1. The pad 34 can buffer the contact between the counterweight 31 and the target body 1, preventing wear between the two, while the counterweight sleeve can surround the pad 34 and the counterweight 31, preventing external environment from causing wear and damage to the device.

[0037] Reference Figure 3 The side wall of the support frame 21 is provided with a rubber plug 24. The rubber plug 24 contacts the connecting rod 22, so that the connecting rod 22 can generate rotational damping on the support frame 21. This prevents the target body 1 from rotating due to slight external force during the positioning process, ensuring the accuracy of positioning, and preventing the target body 1 from rotating too fast, thus avoiding affecting the internal components.

[0038] The implementation principle of this application embodiment is as follows: when it is necessary to perform positioning detection on the wheel hub, simply connect the connecting rod 22 to the middle axle of the wheel hub to be detected, and then under the gravity of the counterweight component, the target body 1 will automatically rotate from the corresponding angle, so that the detection equipment can conveniently and quickly perform positioning detection on the target.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
