Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rail steering, and more specifically, to a hopper rail car with a steering mechanism. Background Art
[0002] In concrete mixing plants and related construction scenarios, efficient and safe material transportation is a key link to ensure construction progress and quality. As a bridge between the mixing plant (or tanker) and the concrete placing crane, the hopper railcar is responsible for transporting concrete and other materials from the production source to the construction site. This type of equipment is usually designed with a dedicated track system to enable precise and fast movement inside or around the mixing plant.
[0003] The design of traditional hopper railcars often relies on a single fixed track to achieve its travel and steering functions. In complex operating environments, especially when multiple tracks intersect or the material conveying path needs to be flexibly adjusted, this single track design is unable to achieve steering over a short distance. Since there are often multiple hopper railcars running on the track at the same time, in order to avoid collisions, the vehicles need to frequently change tracks and turn. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0028] Example 1
[0029] like Figure 1-5As shown, a rail vehicle with a hopper 3 having a steering mechanism includes a chassis support 1, a steering gear, a mounting seat 2 and a hopper 3. A steering gear is installed on the chassis support 1 for controlling the steering of the rail vehicle. Since the wheels 12 cannot be turned at a large angle when rotating on the track, the steering gear is used to achieve simultaneous steering of the front and rear wheels to reduce the turning radius. A mounting seat 2 is also fixedly mounted on the chassis support 1, and a hopper 3 is arranged on the mounting seat 2 for loading materials. The hopper 3 is arranged on the mounting seat 2 for loading materials. The hopper 3 is usually made of metal and has sufficient capacity and strength to carry materials. The shape and size of the hopper 3 can be designed according to specific application requirements, and can be square, round or other shapes. A discharge port can be provided on the hopper 3 for unloading materials.
[0030] The steering gear includes a first connecting frame 4 and a second connecting frame 5 installed on the chassis bracket 1 , and the first connecting frame 4 and the second connecting frame 5 are both rotatably connected to the chassis bracket 1 .
[0031] The first connecting frame 4 and the second connecting frame 5 are respectively installed at the front end and the rear end of the chassis bracket 1. The first connecting frame 4 and the second connecting frame 5 are both connected with a connecting rod 6, and the connecting rod 6 is connected with a steering arm 7. Four steering arms 7 are provided, and the four steering arms 7 are respectively installed at the four corners of the chassis bracket 1. A wheel 12 is rotatably installed on each steering arm 7.
[0032] A connecting seat 8 is installed in the middle of the chassis bracket 1, and a transmission rod 9 is arranged between the connecting seat 8 and the first connecting frame 4. The two transmission rods 9 are respectively connected to the first connecting frame 4, the second connecting frame 5 and the connecting seat 8 through a universal ball joint 13.
[0033] A transmission rod 9 is arranged between the connecting seat 8 and the second connecting frame 5, an extension rod 10 is arranged on the first connecting frame 4, a hydraulic cylinder 11 is arranged between the extension rod 10 and the chassis bracket 1, and both ends of the hydraulic cylinder 11 are respectively hinged to the chassis bracket 1 and the extension rod 10.
[0034] The steering arm 7 is rotatably connected to the chassis bracket 1, and a wheel 12 is rotatably mounted on one end of the steering arm 7. The wheel 12 is provided with a track groove adapted to the track, and the track groove width is slightly larger than the track width to ensure that the four wheels can have sufficient rotation angle when turning. The two ends of the connecting rod 6 are respectively hinged between the steering arm 7 and the first connecting frame 4.
[0035] How it works
[0036] When the rail vehicle needs to turn, the hydraulic cylinder 11 drives the first connecting frame 4 and the second connecting frame 5 to rotate through telescopic motion. The first connecting frame 4 and the second connecting frame 5 drive the steering arm 7 to rotate through the connecting rod 6, thereby realizing the synchronous steering of the front and rear wheels. Since the width of the track groove on the wheel 12 is slightly larger than the width of the track, the wheel 12 has a sufficient rotation angle when turning, thereby reducing the turning radius and enabling the rail vehicle to operate flexibly in a small space. The hopper 3 is used to load and transport materials, and the materials are unloaded through the discharge port.
[0037] The steering gear is used to achieve synchronous steering of the front and rear wheels, effectively reducing the turning radius and improving the flexibility of the rail vehicle in a narrow space. The structure of the connecting seat 8, the transmission rod 9 and the universal ball joint 13 is adopted to ensure the uniform transmission of the steering force and improve the stability and reliability of the steering.
[0038] Example 2
[0039] The difference between the present embodiment and the above-mentioned embodiment is that the loading and unloading of the hopper 3 is described in more detail, a discharge port is arranged on one side of the hopper 3, the side wall of the hopper 3 located on the discharge port side is inclined, a limiting block 14 is arranged on one side of the discharge port, the limiting block 14 is arc-shaped, two limiting blocks 14 are arranged, and the two limiting blocks 14 are respectively located on both sides of the discharge port, a limiting ball 15 is arranged on the limiting block 14, and at least one limiting ball 15 is installed.
[0040] The mounting seat 2 is provided with a limiting groove 16 matched with the limiting ball 15 .
[0041] The mounting base 2 is provided with a fixing column 17, and the hopper 3 is provided with a lock handle 18 matched with the fixing column 17. The inclined side wall and the discharge port design enable the material to flow out more smoothly, while reducing the residual material in the hopper 3.
[0042] The design of the limiting block 14 and the limiting ball 15 and their cooperation during the tilting process effectively prevent the hopper 3 from shifting or shaking during the pouring process, thereby improving the stability of the overall structure.
[0043] When the hopper 3 is loaded with materials, the lock handle 18 is separated from the fixed phase, and the hopper 3 is tilted toward the discharge port under the action of the materials and its own neutrality to pour out the materials. When the hopper 3 is tilted, the limiting ball 15 enters the limiting groove 16 at one time to prevent the hopper 3 from shifting. The inclined side wall and the discharge port design allow the materials to flow out more smoothly, while reducing the residual materials in the hopper 3.
[0044] The design of the limiting block 14 and the limiting ball 15 and their cooperation during the tilting process effectively prevent the hopper 3 from shifting or shaking during the pouring process, thereby improving the stability of the overall structure.
