Description

Technical Field

[0001] The present invention belongs to the field of railway hopper cars, and more specifically, relates to a railway hopper car vibrating unloading device and a railway hopper car. Background Art

[0002] Existing railway hopper cars in China typically feature top-loading and bottom-unloading, with a hopper opening at the bottom, allowing cargo to unload by gravity. The end walls of hopper cars are inclined, generally at an angle equal to the cargo's angle of repose. Furthermore, the car body's bottom is divided into six to eight hopper openings, each separated by a hopper ridge, also inclined at an angle equal to the cargo's angle of repose. Hopper cars transporting bulk cargo such as coal, lime, and clinker are sprayed with dust suppressants or water after loading to prevent dust generation. However, due to the stickiness of the cargo, this can cause it to cling to the angle between the end wall and the hopper ridge, making it difficult to unload completely. Over time, this can lead to cargo compaction and difficulty in cleaning. In such cases, operators typically hammer the end walls or side walls to dislodge the cargo through vibration, or enter the car body and use tools to clean it. These measures are time-consuming and labor-intensive, and can also damage the car body and shorten its service life. Summary of the Invention

[0030] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0031] The present invention provides a vibration unloading device for a railway hopper car, wherein the railway hopper car comprises a side wall portion, an end wall portion, and a back portion, wherein a first angle is formed between the side wall portion and the end wall portion, and a second angle is formed between the end wall portion and the back portion, comprising:

[0032] A main shaft, the middle portion of which passes through the interior of the railway hopper car, the main shaft is connected to the side wall portion through a connecting structure, and the end portion of the main shaft is used to connect to the vibrator;

[0033] A first scraper and a second scraper are arranged on the main shaft, the active surface of the first scraper faces the first angle, and the active surface of the second scraper faces the second angle;

[0034] Under the action of the vibrator, the main shaft can drive the first scraper and the second scraper to perform telescopic movements toward the first angle and the second angle respectively.

[0035] Specifically, on the hopper car, since dust suppressant or water will be sprayed after the goods are loaded, the goods will have a certain degree of stickiness, which will cause the goods to adhere to the first angle and the second angle. The vibrating unloading device is correspondingly provided with a first scraper and a second scraper at the first angle and the second angle. Under the action of the vibrator, the two scrapers can be driven by the main shaft to move telescopically toward the first angle and the second angle seat, so that the scraper can remove the goods at the angle and no longer adhere to the inside of the hopper car; the vibrator drives the scraper to repeatedly move telescopically, which can completely remove the goods without causing damage to the car body.

[0036] Optionally, the side wall is provided with mounting holes, and the connection structure includes:

[0037] The flange is fixedly arranged in the mounting hole, and the main shaft is movably arranged in the flange;

[0038] a vibration seat, threadedly connected to the end of the main shaft;

[0039] The spring is arranged between the flange and the vibration seat.

[0040] Optionally, the main shaft and the side wall parts on both sides are provided with a connection structure, and the compression amount of the springs on both sides is the same.

[0041] Specifically, the main shaft is arranged parallel to the end wall part and passes through the flange. A spring and a vibration seat are sequentially sleeved on the main shaft part outside the flange. The vibration seat and the main shaft are detachably connected, which facilitates the later disassembly and maintenance of the vibrating unloading device; the spring is installed between the vibration seat and the flange, and the spring is in a pre-compressed state. The spring compression amount on both sides of the car body is the same, so that the main shaft is in the center position of the hopper car when it is in a free state; in addition, the spring is arranged to buffer the force on the car body during the movement of the main shaft to avoid damage.

[0042] Optionally, the end sleeve of the main shaft is provided with an anti-loosening gasket, a keyhole is opened in the middle of the anti-loosening gasket, and two bending parts are relatively provided on the outer periphery of the anti-loosening gasket, the keyhole matches the cross-section of the main shaft, a boss is provided on the vibration seat, and the outer periphery of the boss is provided with a surface matching the bending part.

[0043] Specifically, when the vibration seat and the main shaft are threadedly connected, in order to prevent the vibration seat and the main shaft from loosening, an anti-loosening gasket is provided on the vibration seat, and a keyhole is provided in the middle of the anti-loosening gasket, which matches the outer peripheral shape of the main shaft. The two will not rotate after being installed. A boss is processed at the end of the vibration seat. After the vibration seat and the main shaft are tightened, the two bent parts of the anti-loosening gasket are folded up, and the bent parts can be affixed to the two sides of the boss of the vibration seat. In this way, the anti-loosening gasket is also fixed to the position of the vibration seat, so that the vibration seat cannot be loosened due to rotation.

[0044] Optionally, an anti-loosening gasket is provided between the spring and the vibration seat.

[0045] Specifically, when the vibrating unloading device is installed on the hopper car, after the main shaft is passed through the hopper car, the spring, anti-loosening gasket and vibration seat are installed in sequence on the end of the main shaft. The anti-loosening gasket cannot continue to rotate under the clamping fit of the main shaft. The anti-loosening gasket applies extrusion force to the spring, leaving sufficient operating space for the installation of the vibration seat and the main shaft.

[0046] Optionally, two first scrapers are provided on the main shaft, the first scrapers are L-shaped, the long side of the first scraper cooperates with the end wall part, and the short side of the first scraper is connected to the main shaft through a first connecting rod.

[0047] Optionally, the main shaft is centrally arranged on the first scraper.

[0048] Specifically, two first scrapers are provided between the two side wall parts where the main shaft is located, and the long sides of the first scrapers are in contact with or form an angle with the end wall part, so that when the first scraper is driven by the main shaft to move toward the side wall part, the first scraper can scrape off the residual goods on the surface of the end wall part and within the first angle; the short sides of the first scraper are connected to the main shaft through the first connecting rod, and the main shaft is set at the midpoint of the first scraper, so that when the first scraper is driven to move, the first scraper will not affect the connection strength with the first connecting rod due to uneven force.

[0049] Optionally, two second scrapers are provided on the main shaft, the two second scrapers are in an eight-shape, and are respectively provided on both sides of the spine part. The second scraper is L-shaped, the long side of the second scraper is matched with the end wall part, and the short side of the second scraper is connected to the main shaft through a second connecting rod.

[0050] Optionally, the second scraper and the back portion have the same inclination angle.

[0051] Specifically, the second scraper is arranged on both sides of the spine of the hopper car, and the angle of the second scraper is parallel to the spine, so that when the main shaft drives the second scraper to move toward the spine, the long side of the second scraper can be completely aligned with the second angle, thereby improving the effect of clearing residual cargo; there are no less than two second connecting rods between the second scraper and the main shaft, and the length of each second connecting rod is different, so that the angle between the second scraper and the main shaft can be formed to match the spine.

[0052] Since the first scraper and the second scraper are both set to be L-shaped, the main shaft and the end wall part leave at least the length of the short side of the scraper, so that the scraper can clear the residual goods on the end wall part, and the main shaft and the end wall part are separated by a certain distance, which will not affect the normal unloading of the hopper car.

[0053] The present invention also provides a railway hopper car, comprising the above-mentioned railway hopper car vibrating unloading device.

[0054] Specifically, when unloading existing hopper trucks, cargo often remains at the junctions of the end wall and side wall, or at the junction of the end wall and hopper. This accumulation of cargo over time can lead to compaction, making it more difficult to clean. Currently, operators often use hammering to clean cargo: using a sledgehammer to strike the car body where cargo remains, vibrating the body and releasing the cargo. This method can cause abnormal damage to the car body, such as dents or cracks, and shorten the vehicle's service life. Some operators use vibrators directly to vibrate the car body. Low vibrator power can be ineffective, while high power can cause cracks in the car body or welds where the vibrator contacts the vehicle. When this vibrating unloading device is installed on the hopper truck, the vibration force is applied to the vibrating base, not directly to the hopper truck body. A spring provides buffering, minimizing damage to the body. First and second scrapers are positioned within the hopper truck at locations prone to cargo accumulation, directly separating the cargo from the car body and ensuring complete unloading. If a vibrating motor is not available, hammering the vibrating base with a hammer can also effectively remove cargo from the car body.
