A split type unloading rail

Abstract

This utility model discloses a disassembled unloading curved track, including a base frame with several evenly arranged support legs on the top of the base frame. A base plate is fixedly connected to the top of all the support legs. Multiple curved track sections are detachably fixed to the top of the base plate, and adjacent curved track sections are smoothly connected to each other. This disassembled unloading curved track is easy to maintain, as it can be disassembled and replaced individually without replacing the entire track, reducing maintenance costs and time. It also offers good thermal stability, with pre-reserved thermal expansion gaps effectively relieving temperature stress, preventing thermal expansion deformation of the curved track, and extending the equipment's service life. Furthermore, its installation flexibility allows the multi-segment splicing structure to adapt to complex curved track layouts, facilitating on-site installation and adjustment.

Description

Technical Field

[0001] This utility model relates to the field of mining machinery, specifically a disassembled unloading curved track. Background Technology

[0002] In coal mines, unloading curved tracks are key equipment used to support and guide mine cars during the unloading process. Traditional unloading curved tracks typically employ a monolithic structure, where the curved track surface is a single, non-removable unit, such as... Figure 1 As shown. This structure has the following significant drawbacks in practical applications:

[0003] High maintenance costs: When the curved rail surface is partially worn or damaged, the entire curved rail needs to be replaced, resulting in high maintenance costs, long downtime, and serious impact on production efficiency.

[0004] Insufficient thermal stability: In the high-temperature environment of cast iron production, integral curved rails are prone to deformation or cracking due to thermal expansion and contraction. The lack of thermal expansion margin design will lead to a decrease in rail accuracy after long-term use, which may cause workpiece jamming, unloading difficulties or even equipment failure.

[0005] Installation and adjustment are difficult: The integral curved track has extremely high requirements for installation accuracy, and the on-site installation and calibration of complex curved tracks are difficult, making it difficult to adapt to the layout requirements of different production scenarios. Utility Model Content

[0006] The purpose of this invention is to provide a decomposed unloading curve track to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a decomposable unloading curved track, including a base frame, with several evenly arranged support legs on the top of the base frame, and a base plate fixedly connected to the top of all the support legs. Multiple curved track surfaces are detachably fixed to the top of the base plate, and adjacent curved track surfaces are connected to each other smoothly.

[0008] Preferably, the curved track surface and the base plate are fixed together by connecting bolts.

[0009] Preferably, a gap of 2-5mm is provided between the ends of two adjacent curved rail surfaces to allow for thermal expansion.

[0010] Preferably, the top of the curved track surface is an arc surface with a diameter of 80, and the bottom of the curved track surface is fitted to the top surface of the base plate.

[0011] Preferably, the base plate and the curved track surface have the same curvature along the extension direction of the curved track.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model discloses a disassembled unloading curved track, which breaks down the traditional integral curved track into multiple detachable units, significantly improving the following performance:

[0014] Convenience of maintenance: When a section of the curved track is worn or damaged, it can be disassembled and replaced separately without replacing the entire track, reducing maintenance costs and time.

[0015] Thermal stability: The reserved thermal expansion gap effectively relieves temperature stress, prevents the curved track from thermally expanding and deforming, and extends the service life of the equipment.

[0016] Installation flexibility: The multi-segment splicing structure can adapt to complex curved track layouts, facilitating on-site installation and adjustment. Attached Figure Description

[0021] 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.

[0022] The disassembled unloading curved rail of this utility model mainly consists of a base frame 1, support legs 2, base plate 3, curved rail surface 4, and connecting bolts 5. The components are assembled in the following manner:

[0023] Base frame 1 and support legs 2: Multiple support legs 2 are evenly welded to the top of the base frame 1. The support legs 2 are perpendicular to the surface of the base frame 1 and form a stable support structure through welding.

[0024] Base plate fixing: The top of all the outriggers 2 are fixed to the base plate 3 by bolts or welding. The base plate 3 is a planar structure and its size matches the distribution of the outriggers 2 to ensure uniform force distribution.

[0025] Curved rail surface installation: Multiple curved rail surfaces 4 are detachably fixed to the top of the base plate 3 via connecting bolts 5. Specifically, the bottom of the curved rail surface 4 is machined with a flat surface that fits against the top surface of the base plate 3. Bolts are passed through the mounting holes of the curved rail surface 4 and connected to the threaded holes of the base plate 3 to achieve detachable fixing.

[0026] Key Design of Curved Track Surface

[0027] Curved surface structure: The top of the curved track surface 4 is an arc surface with a diameter of 80 mm. This arc surface is used to support the mine car to be unloaded. The arc design can reduce the friction between the workpiece and the curved track surface, and facilitate sliding unloading.

[0028] Curvature matching: The base plate 3 and the curved track surface 4 have the same curvature along the extension direction of the curved track, ensuring that the multiple curved track surfaces 4 are spliced ​​together to form a continuous and smooth curved track, avoiding jamming or impact caused by sudden changes in track curvature during workpiece operation.

[0029] Thermal expansion allowance design: A gap of 2-5mm is reserved between the ends of two adjacent curved rail surfaces 4. This gap serves as a thermal expansion allowance to prevent the curved rail surface from deforming or being damaged due to thermal expansion caused by temperature changes, thus ensuring the long-term stable operation of the track.

[0030] Assembly and debugging process

[0031] Basic installation: First, fix the base frame 1 to the ground or equipment base, and adjust the level of the base frame 1 with a level to ensure that the support legs 2 are evenly stressed.

[0032] Base plate positioning: Place the base plate 3 on the top of the support leg 2, calibrate the position of the base plate 3 with measuring tools to ensure that its curvature along the extension direction of the curved track meets the design requirements, and then fix the base plate 3.

[0033] Curved rail surface splicing: Place each curved rail surface 4 on top of the base plate 3 in sequence, adjust the mating position of adjacent curved rail surfaces 4 to ensure a smooth connection (error not exceeding 0.5mm), and then fix it with connecting bolts 5. During installation, check the gap size to ensure that each gap is within the range of 2-5mm.

[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.
