Description

Technical Field

[0001] This utility model relates to the field of railway maintenance, and in particular to a ballast collection device for a ballast railway bucket wheel cleaning machine. Background Technology

[0002] Ballast is a special type of stone used in railway engineering. It is made from hard rocks such as granite and basalt through crushing and other processes. Ballast is typically placed under the track to improve its stability. After prolonged use, combined with rainwater erosion and dust settling, the ballast bed can experience problems such as settlement, frost heave, and voids. Therefore, a ballast cleaning machine is needed to clean and screen the ballast to restore its elasticity. The bucket wheel ballast cleaning machine uses bucket wheels on both sides as the digging device. However, because there is no mechanism to gather the ballast in the digging direction, the digging efficiency is relatively slow. Utility Model Content

[0003] In view of this, the present invention proposes a ballast collection device for a bucket wheel type screen cleaner, in order to improve the digging efficiency of the screen cleaner.

[0004] The present invention adopts the following technical solution: This utility model provides a ballast collection device for a bucket wheel screen cleaning machine. The ballast collection device consists of a movable flared opening and a main structure, including an upper hydraulic cylinder, a frame, side hydraulic cylinders, a first front hydraulic cylinder, an inner flap door, a second front hydraulic cylinder, an outer flap door, a lifting hydraulic cylinder, and a bottom hydraulic cylinder. One end of the upper, side, and bottom hydraulic cylinders is connected to the frame, and the other end is connected to the bucket wheel screen cleaning machine. During operation, the upper, side, and bottom hydraulic cylinders are in a floating state. When the device reaches the working position, the upper and side hydraulic cylinders... Both the inner and bottom hydraulic cylinders are locked to resist the impact of ballast. The inner and outer flap doors form a movable flared opening with the frame. The first and second front hydraulic cylinders are respectively located between the inner flap door and the frame and between the outer flap door and the frame. By extending or shortening, the opening size of the flared opening is controlled, thereby controlling the amount of ballast flowing to the bucket wheel. The lifting hydraulic cylinder is installed on the outer flap door. The extension of the lifting hydraulic cylinder pushes the movable plate of the outer flap door to move, thereby increasing the area of ​​the outer flap door.

[0005] This utility model also provides a ballast collection device for a bucket wheel type screen cleaning machine. One end of the lifting hydraulic cylinder is fixed to the base plate of the outer flap door by a pin, and the other end is connected to a fixed button block and a sliding button block by a connecting rod. The fixed button block is fixed to the base plate, and the sliding button block is fixed to the movable plate. The base plate is equipped with a guide groove, and there is a guide post in the groove. The guide post is fixed to the movable plate. When the lifting hydraulic cylinder extends, it compresses the connecting rod outward, causing the sliding button block to slide downward in the guide groove, pushing the movable plate to move downward. The remaining guide posts are forced to slide downward in the guide groove, which guides the downward movement of the movable plate.

[0006] This utility model also provides a ballast collection device for a bucket wheel type screen cleaning machine. When collecting the ballast, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are set to a floating state. When the device reaches the collection position, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are locked to prevent the device from loosening. The lifting hydraulic cylinder is shortened to reduce the area of ​​the outer flap door and reduce the collection volume.

[0007] This utility model also provides a ballast collection device for a bucket wheel type screen cleaning machine. When the lifting hydraulic cylinder is shortened, the connecting rod is stretched inward, causing the sliding button block to slide upward in the guide groove, pushing the movable plate to move upward. The remaining guide columns are forced to slide upward in the guide groove, which plays a guiding role in the lifting and movement of the movable plate.

[0008] This utility model also provides a ballast collection device for a bucket wheel type screen cleaning machine, which uses bolts and insert plates to connect the bucket wheel wing plate to the frame. The bucket wheel wing plate and the frame are provided with corresponding insert plate grooves for forming a straight insertion structure between the insert plate and the frame and the bucket wheel wing plate. The bucket wheel wing plate and the frame are provided with corresponding bolt holes for bolt connection.

[0009] This utility model also provides a ballast collection device for a bucket wheel type cleaning screen, wherein the frame is made of replaceable wear-resistant material.

[0010] This utility model also provides a method for operating the ballast collection device as described above, including the following steps: 1) During operation, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are in a floating state. When the device reaches the working position, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are all locked to resist the impact of ballast; 2) The first front hydraulic cylinder and the second front hydraulic cylinder extend, and the inner flap door and the outer flap door open, forming a flared opening with the frame; 3) The lifting hydraulic cylinder extends to increase the area of ​​the outer flap door and enlarge the flared opening; 4) When collecting the ballast, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are set to a floating state. When the device reaches the collection position, the upper hydraulic cylinder, side hydraulic cylinder, and bottom hydraulic cylinder are locked to prevent the device from loosening; the lifting hydraulic cylinder shortens to reduce the area of ​​the outer flap door, reduce the collection volume, and facilitate collection and preparation.

[0011] In situations where the track bed is wide enough to collect a large amount of ballast, the first and second front hydraulic cylinders can be extended to increase the opening angle and allow more ballast to flow into the excavating bucket wheel. When the device is retracted, the first and second front hydraulic cylinders are retracted to reduce the space occupied by the device.

[0012] Technical effects of this utility model: 1. The gathering of ballast.

[0013] In bucket wheel-type ballast cleaning machines, the amount of ballast in front of the bucket wheel during operation is relatively small, resulting in low ballast collection efficiency. The ballast collection device features a funnel-shaped opening at the front, with a lifting hydraulic cylinder 8 on the outer side of the opening. This allows the side plate to be lowered, widening the funnel and collecting ballast in front of the bucket wheel over a wider area, significantly improving digging efficiency. Furthermore, the opening angle of the funnel is controlled by a first front hydraulic cylinder 4 and a second front hydraulic cylinder 6. In situations where the track bed is wide and more ballast needs to be collected, the first and second front hydraulic cylinders 4 and 6 can be extended to increase the opening angle, allowing more ballast to flow into the digging bucket wheel. When the device is retracted, the hydraulic cylinders are withdrawn, reducing the space occupied by the device.

[0014] 2. Fixing the device.

[0015] The ballast collection device, installed at the front of the bucket wheel, is the main component subjected to ballast impact. To improve the device's rigidity against ballast impact, three hydraulic cylinders—upper hydraulic cylinder 1, side hydraulic cylinder 3, and bottom hydraulic cylinder 9—are used to enhance the device's rigidity. During the device's retraction and extension, the hydraulic cylinders float and can extend or shorten according to the force applied; once in position, the hydraulic cylinders lock, providing rigid support for the device and further increasing its rigidity.

[0016] 3. Durability of the ballast collection device Since the ballast collection device comes into contact with and rubs against the ballast for a long time, the frame 2 of the ballast collection device is made of replaceable wear-resistant material, which not only improves the durability of the device, but also allows it to be replaced after severe wear.

[0017] Lifting hydraulic cylinder controls the unfolding area of ​​the outer flap door The lifting hydraulic cylinder 8 can extend to further increase the area of ​​the trapdoor 7, thereby collecting ballast more efficiently. After the operation is completed, the lifting hydraulic cylinder 8 retracts, reducing the area of ​​the trapdoor 7 and saving space when the vehicle is being moved back in.

[0018] Connection method between bucket wheel and ballast collection device To balance the robustness of the connection between the bucket wheel and the ballast collection device with ease of disassembly, six bolts (17 in total) and insert plates (17) are used to connect the bucket wheel blade 19 to the frame 2. This connection method ensures that the bolts are only subjected to tensile force, while the shear force is borne by the insert plates (17), thereby indirectly improving the robustness of the bolt connection. The insert plates (17) and the frame 2 and bucket wheel blade 19 adopt a simple direct insertion structure without mutual locking anti-detachment structures, which improves the convenience of disassembly.

[0025] 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.

[0026] like Figure 2 As shown, the ballast collection device consists of an upper hydraulic cylinder 1, a frame 2, a side hydraulic cylinder 3, a first front hydraulic cylinder 4, an inner flap door 5, a second front hydraulic cylinder 6, an outer flap door 7, a lifting hydraulic cylinder 8, and a bottom hydraulic cylinder 9.

[0027] During operation, the upper hydraulic cylinder 1, side hydraulic cylinder 3, and bottom hydraulic cylinder 9 are in a floating state. Once the device reaches the working position, all three are locked to resist the impact of the ballast. Simultaneously, the first front hydraulic cylinder 4 and the second front hydraulic cylinder 6 extend, opening the inner flap door 5 and the outer flap door 7, forming a funnel shape with the frame 2. Clearly, the lengths of the first front hydraulic cylinder 4 and the second front hydraulic cylinder 6 control the opening size of the funnel, thereby controlling the amount of ballast flowing to the bucket wheel. Extending the lifting hydraulic cylinder 8 increases the area of ​​the outer flap door 7, further increasing the size of the funnel.

[0028] One end of the lifting hydraulic cylinder 8 is fixed to the base plate 12 by a pin, and the other end is connected to the fixed button block 11 and the sliding button block 10 by a connecting rod 14. The fixed button block is fixed to the base plate 12, and the sliding button block 10 is fixed to the movable plate. The base plate 12 is equipped with a guide groove 15, and there is a guide post 16 in the groove. The guide post 16 is fixed to the movable plate 13. When the lifting hydraulic cylinder 8 extends, it compresses the connecting rod 14 outward, causing the sliding button block 10 to slide downward in the guide groove 15, pushing the movable plate 13 to move downward. The remaining guide posts 16 are forced to slide downward in the guide groove 15, guiding the downward movement of the movable plate 13.

[0029] When the vehicle is being retracted, the upper hydraulic cylinder 1, side hydraulic cylinder 3, and bottom hydraulic cylinder 9 are set to a floating state. When the device reaches the retraction position, the upper hydraulic cylinder 1, side hydraulic cylinder 3, and bottom hydraulic cylinder 9 are locked to prevent the device from loosening. The lifting hydraulic cylinder 8 is shortened to reduce the area of ​​the outer hatch, thereby reducing the retraction volume and facilitating vehicle preparation.

[0030] When the lifting hydraulic cylinder 8 is shortened, the connecting rod 14 is stretched inward, causing the sliding button block 10 to slide upward in the guide groove 15, pushing the movable plate 13 to move upward. The remaining guide columns 16 are forced to slide upward in the guide groove 15, which guides the lifting movement of the movable plate 13.

[0031] To balance the robustness of the connection between the bucket wheel and the ballast collection device with ease of disassembly, six bolts (17 in total) and insert plates (17) are used to connect the bucket wheel blade 19 to the frame 2. This connection method ensures that the bolts are only subjected to tensile force, while the shear force is borne by the insert plates (17), thereby indirectly improving the robustness of the bolt connection. The insert plates (17) and the frame 2 and bucket wheel blade 19 adopt a simple direct insertion structure without mutual locking anti-detachment structures, which improves the convenience of disassembly.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
