Abstract
Description
Technical Field
[0001] This utility model relates to the field of unloading mine car technology, specifically to an unloading curved track positioning tooling. Background Technology
[0002] Figure 1 This is a schematic diagram of a bottom-unloading mine car in the prior art. In the diagram, the unloading wheels of the mine car move along a curved rail, the bottom of the mine car is opened, and the ore is unloaded from below. The installation position of the curved rail is crucial for the smooth unloading of the mine car. Due to discrepancies between actual field conditions and drawings, installation has been a challenge for many years. Without proper installation, testing is impossible, and without testing, it's impossible to know if the curved rail installation position is correct. Therefore, a tooling fixture was created to align the curved rail position and assist in successful installation. Utility Model Content

[0016] 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.
[0017] As shown in Figures 1 to 4, the unloading curved track position alignment fixture of this utility model includes the following core components:
[0018] Unloading pit 1: As a basic structure used for tooling, it is equipped with unloading curved track 3 inside, and combined idler rollers 2 are fixedly installed on both sides.
[0019] Alignment fixture 4: Moving part 401: It is a rectangular frame structure with its opposite sides mounted on the combined rollers 2 on both banks. It is used to simulate the body of a mine car. It can be moved smoothly along the combined rollers 2 by workers pushing it. The moving part 401 is made of welded steel bars.
[0020] Suspension part 402: Fixed below the moving part 401, it has a bracket-like structure and is used to connect the inspection part 403. The suspension part 402 is also made of welded steel bars and is welded to the moving part 401.
[0021] Inspection section 403: It is a rod structure with a fixed sleeve 404 at the top. The sleeve 404 is rotatably connected to the shaft of the suspension section 402, so that the inspection section 403 can rotate freely around the suspension section 402. The bottom end is designed as a smooth contact surface, which can be placed on the unloading curved track 3 to simulate the movement trajectory of the unloading wheel of the mine car.
[0022] The usage method of this tool is as follows:
[0023] 1. Initial Installation Steps
[0024] Place the moving part 401 of the alignment fixture 4 on the combined roller 2, and manually adjust it so that the moving part 401 is as close as possible to the middle position of the combined roller 2 to ensure the balance reference when the fixture moves.
[0025] Check the contact status between the moving part 401 and the combined idler roller 2 to ensure that the two sides of the rectangular frame are in close contact with the surface of the idler roller without any obvious tilting or jamming.
[0026] 2. Center position detection
[0027] The bottom end of the inspection section 403 is gently placed on the top surface of the unloading curved track 3. At this time, the sleeve 404 can rotate freely on the suspension section 402, so that the inspection section 403 adapts to the curvature of the curved track.
[0028] Observe from the direction perpendicular to the curved track whether the bottom end of the inspection section 403 is aligned with the center axis of the unloading curved track 3: If the bottom end of the inspection section 403 deviates from the center of the curved track, it proves that the installation position of the unloading curved track 3 is offset and the position of the curved track needs to be adjusted; if the bottom end of the inspection section 403 falls accurately at the center of the curved track, proceed to the next step.
[0029] 3. Dynamic trajectory simulation
[0030] The moving part 401 is pushed smoothly along the length of the combined idler roller 2, so that the alignment fixture 4 moves slowly along the curved track 3, simulating the movement of the unloading wheel of the mine car. The position change of the bottom of the inspection part 403 on the curved track 3 is observed throughout the process: if the inspection part 403 always stays in the center position of the curved track and does not deviate to the left or right, it proves that the installation trajectory of the unloading curved track 3 meets the requirements. If the inspection part 403 deviates from the center during the movement, it indicates that there is a position error in the installation of the curved track, and the fixed position of the curved track 3 needs to be adjusted until the dynamic trajectory of the inspection part 403 meets the requirements.
[0031] Tooling working principle explanation
[0032] Simulated mine car movement: The moving part 401 simulates the mine car body, the combined roller 2 is the mine car running track, and the inspection part 403 simulates the mine car unloading wheel turning with the curved track by rotating the sleeve 404.
[0033] Detection logic: By observing the relative positional change between the inspection unit 403 and the center of the curved track, the deviation of the curved track installation is intuitively reflected. The combination of static center alignment detection and dynamic trajectory simulation ensures the accuracy of the curved track position and helps the curved track to be installed correctly.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
