Description

Technical Field

[0001] This utility model relates to the field of tippler technology, specifically to a tippler platform sliding device. Background Technology

[0002] A tippler unloading system is a large-scale automatic unloading system used in power plants, ports, metallurgy, coal, coking and other enterprises. It is a device that can unload bulk materials loaded on open railway wagons. The "O" type tippler is used to unload loaded wagons that have been towed in by mechanical clamping and approaching actions. It is a key piece of equipment for transferring materials to the material yard or combustion zone. The "O" type tippler is an important single unit component of the tippler unloading system, and the platform device is an even more important component of the tippler.

[0003] The "O"-type tippler mainly consists of end rings, a front beam, a rear beam, a platform, and a wagon-holding plate. The front beam, rear beam, platform, and end rings are connected to each other via flanges secured with high-strength bolts, and all are box-beam structures. The original design of the "O"-type tippler relied on its own weight for platform sliding. However, this sliding action often resulted in the platform failing to properly hold the wagon, lacked limit switches, and posed significant safety hazards. Utility Model Content

An electric hydraulic push rod drives a torque arm to rotate, the torque arm drives a connecting arm to move, and the connecting arm drives the platform to slide relative to the tippler base to generate displacement, making the sliding of the platform more controllable and reducing the phenomenon of the platform not being able to properly align with the vehicle.

[0005] To achieve the above objectives, the present invention provides a sliding device for a tippler platform, comprising a tippler base, a platform, a vehicle support plate, and a linkage assembly. The platform is slidably disposed on the tippler base and is provided with a vehicle positioning part. The vehicle support plate is disposed on the tippler base. The linkage assembly includes an electro-hydraulic push rod hinged to the vehicle support plate, a torque arm hinged to the output end of the electro-hydraulic push rod, and a connecting arm hinged to the torque arm. The torque arm is hinged to the tippler base, and the connecting arm is hinged to the platform.

[0006] Furthermore, the support plate is positioned perpendicular to the sliding direction of the platform.

[0007] Furthermore, a wear-resistant rubber plate is provided on the upper part of the vehicle support plate.

[0008] Furthermore, a support leg is provided on each side of the electro-hydraulic push rod.

[0009] Furthermore, the outriggers are connected to the vehicle support plate and the tipper base, respectively.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] See Figure 1 and Figure 2 The diagram illustrates a tippler platform sliding device, which includes a tippler base 100, a platform 200, a vehicle support plate 300, and a linkage assembly 400. The platform 200 is slidably disposed on the tippler base 100, and the vehicle support plate 300 is disposed on the tippler base 100. The platform 200 is provided with a vehicle positioning part 210. The linkage assembly 400 includes an electro-hydraulic push rod 410 hinged to the vehicle support plate 300, a torque arm 420 hinged to the output end of the electro-hydraulic push rod 410, and a connecting arm 430 hinged to the torque arm 420. The torque arm 420 is hinged to the tippler base 100, and the connecting arm 430 is hinged to the platform 200.

[0018] When the tippler platform sliding device is working, the vehicle 10 is placed on the platform 200, and the vehicle positioning unit 210 positions the vehicle. The positioning method can adopt the existing tippler platform positioning method. The electro-hydraulic push rod 410 drives the torque arm 420 to rotate, the torque arm 420 drives the connecting arm 430 to move, and the connecting arm 430 drives the platform 200 to slide relative to the tippler base 100. Specifically, the electro-hydraulic push rod 410 is equipped with an interlock signal, and the system controls the electro-hydraulic push rod 410 to have a limit function. In this embodiment, the sliding distance of the platform 200 towards the vehicle support plate 300 is approximately 200mm, controlled by the electrical system according to actual conditions. Furthermore, the hinge method in this embodiment includes, but is not limited to, shaft connections.

[0019] The aforementioned tipper platform sliding device is equipped with a linkage assembly 400 to form a four-bar linkage mechanism. The electric hydraulic push rod 410 serves as the power source, transmitting kinetic energy through the four-bar linkage to drive the platform 200 to slide horizontally, so that the vehicle 10 is brought close to the vehicle support plate 300. During this process, the position and stroke of the platform 200 are controllable, the positioning is relatively accurate, and the safety is good.

[0020] See Figure 2 and Figure 3 In one embodiment, the vehicle support plate 300 is positioned perpendicular to the sliding direction of the platform 200. In this embodiment, the vehicle support plate 300 is vertically positioned, and the platform 200 can slide horizontally relative to the tipper base 100.

[0021] In one embodiment, a wear-resistant rubber plate 310 is provided on the upper part of the vehicle support plate 300. In this embodiment, adding a wear-resistant rubber plate 310 to the vehicle support plate 300 of the tipper can protect the vehicle 10 and reduce the impact on the vehicle support plate 300.

[0022] In one embodiment, a support leg 440 is provided on each side of the electro-hydraulic push rod 410. The support leg 440 can strengthen the electro-hydraulic push rod 410 and prevent the electro-hydraulic push rod 410 from deforming under force.

[0023] In one embodiment, the outrigger 440 is connected to the vehicle support plate 300 and the tipper base 100, respectively.

[0024] In one embodiment, two linkage assemblies 400 are provided and disposed on both sides of the vehicle-mounted plate 300. In this embodiment, two sets of linkage assemblies 400 are provided and fixed to the vehicle-mounted plate 300 of the tipper, respectively, and are evenly distributed, such as... Figure 1 As shown, the center-to-center distance between the two link assemblies 400 is 11440mm.

[0025] In one embodiment, the bottom of the platform 200 is provided with rollers 220, and the tipper base 100 is provided with a track 110, with the rollers 220 making rolling contact with the track 110.

[0026] See Figure 4 In one embodiment, the torque arm 420 has a first hinge point 421, a second hinge point 422, and a third hinge point 423 located between the first hinge point 421 and the second hinge point 422. The first hinge point 421 is hinged to the output end of the electro-hydraulic push rod 410, the second hinge point 422 is hinged to the connecting arm 430, and the third hinge point 423 is hinged to the tipper base 100. Further, a reinforcing support is provided at the third hinge point 423. Specifically, the torque arm 420 is irregularly shaped, equivalent to a cam shape, and the electro-hydraulic push rod 410 pushes the torque arm 420 to perform cam motion. The electro-hydraulic push rod 410 is fixed inside the backrest plate 300 and fixed and reinforced by support legs 440, which are welded to the backrest plate 300 to prevent deformation of the electro-hydraulic push rod 410 under stress. A reinforcing support is provided below the torque arm 420 to prevent deformation. The thickness of the torque arm 420 is not less than 50mm to meet the stress requirements.
