Description

Technical Field

[0001] This utility model relates to the field of tippler technology, specifically to a centrally located end ring for a double-car tippler. Background Technology

[0002] A three-point double-car tippler is a heavy-duty mechanical device specifically designed for unloading railway open wagons, widely used in thermal power plants, coal chemical plants, cement plants, and ports. Due to its high unloading efficiency, it is increasingly adopted by power plants and ports in China. A three-point double-car tippler consists of two independent C-type single-car tipplers connected in series via a synchronization device. Besides the synchronous drive requirements of the power system, a connecting mechanism is also needed between the two cars to ensure synchronized operation. Existing double-car tipplers can achieve synchronized operation through the power system, but there is no mechanical synchronization connection mechanism between the individual cars. If a phase difference occurs during the tipping process, torque will be generated between the two open wagons, adversely affecting the connection device between the open wagons. Summary of the Invention

[0003] This invention addresses the problem that existing three-point double-car tipplers lack a mechanical synchronization connection mechanism between individual units, leading to phase differences during tipping and torque between the two open wagons, which adversely affects the connection device between the open wagons. It provides a centrally located end ring for the double-car tippler, enabling synchronous operation between two single-car tipplers. This ring is simple to install and maintain, and has a long service life.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A centrally located end ring for a dual-vehicle tipper includes an exit end ring at the rear of a first tipper and an entry end ring at the front of a second tipper. A synchronization device is provided between the exit end ring and the entry end ring. The synchronization device includes a first base and a second base that are engaged with each other. The first base is disposed on the exit end ring, and the second base is disposed on the entry end ring. A height adjustment component is provided on either the first or second base for adjusting the height of the first or second base. The synchronization device is used for the synchronized rotation of the exit end ring and the entry end ring.

[0006] Furthermore, threaded holes are provided on the outer circumference of both the exit end ring and the entry end ring, and brackets are provided on the opposite outer sides of the exit end ring and the entry end ring. The brackets and threaded holes are used to fix the ring rail.

[0007] Furthermore, two synchronization devices are provided between the vehicle exit ring and the vehicle entry ring. The lines connecting the two synchronization devices to the center point of the end ring form an angle of 140° to 160°. The two synchronization devices work together to achieve synchronous rotation of the vehicle exit ring and the vehicle entry ring.

[0008] Furthermore, the first base has a convex cross-section, and the second base has a concave cross-section, with the convex part of the first base matching the concave part of the second base. During rotation, the first and second bases engage with each other.

[0009] Furthermore, positioning blocks are provided on both sides of the first base. The bottom of the positioning block is fixedly connected to the vehicle exit ring, and the inner side of the positioning block is in contact with the first base. The positioning blocks are used to increase the structural strength of the first base.

[0010] Furthermore, positioning blocks are provided on both sides of the second base. The bottom of the positioning blocks is fixedly connected to the vehicle entry end ring, and the inner side of the positioning blocks is in contact with the second base. This increases the structural strength of the second base.

[0011] Furthermore, the height adjustment assembly includes a pad and a bolt. The pad matches a first base or a second base, and the bolt secures the pad to the first base or the second base. The height of the first base or the second base can be adjusted by adjusting the height or number of pads.

[0012] Furthermore, the first base includes a first connecting part and a first fixing part. The first connecting part engages with the contact surface of the second base. The pad is disposed between the first connecting part and the first fixing part. The first fixing part is fixedly connected to the vehicle exit end ring. The height of the first base is adjusted using the pad.

[0013] Furthermore, the second base includes a second connecting part and a second fixing part. The second connecting part engages with the contact surface of the first base. The pad is disposed between the second connecting part and the second fixing part. The second fixing part is fixedly connected to the vehicle entry end ring. The height of the second base is adjusted using the pad.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This invention features a synchronization device between the exit ring and the entry ring. The synchronization device includes a first base and a second base that are engaged. A height adjustment component is provided on the first base or the second base to adjust the height of the first base or the second base. This invention has a simple structure, can achieve synchronous operation between two single-vehicle tippers, and is easy to install and maintain with a long service life. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-4 As shown, this embodiment provides a centrally located end ring for a dual-vehicle tipper.

[0023] The centrally located end ring includes the vehicle exit end ring 1 at the rear end of the first tippler and the vehicle entry end ring 2 at the front end of the second tippler, such as... Figure 1 As shown, a synchronization device 3 is provided between the vehicle exit ring 1 and the vehicle entry ring 2.

[0024] like Figure 2 As shown, threaded holes are provided on the outer circumference of both the exit ring 1 and the inlet ring 2. A bracket 21 is provided on the opposite outer sides of the exit ring 1 and the inlet ring 2. The bracket 21 and the threaded holes are used to fix the ring rail 22. Specifically, on the inner side of the ring rail 22, bolts are directly passed through the ring rail 22 and screwed into the threaded holes to fix the inner side of the ring rail 22; on the outer side of the ring rail 22, bolts are passed through the ring rail 22 and the bracket, and a nut is fitted to it to fix the outer side of the ring rail 22. To enhance the stability of the connection, a ring rail pressure plate 23 is provided between the ring rail 22 and the bolt head. This installation method occupies little space and facilitates on-site installation and maintenance of the equipment.

[0025] like Figure 3 As shown, two synchronization devices 3 are provided between the exit end ring 1 and the entry end ring 2. The lines connecting the two synchronization devices 3 to the center point of the end ring form an angle of 140° to 160°. In this embodiment, the included angle between the lines connecting the two synchronization devices 3 to the center point of the end ring is 150.5°. The two synchronization devices 3 can achieve synchronous rotation of the exit end ring 1 and the entry end ring 2, and the force on the synchronization devices 3 is relatively uniform. Compared with a single synchronization device 3, the force is more stable and less prone to damage.

[0026] like Figure 4As shown, the synchronization device 3 includes a first base 4 and a second base 5 that are engaged with each other. When the tipper rotates, the first base 4 and the second base 5 rotate synchronously. The first base 4 is mounted on the exit end ring 1, and the second base 5 is mounted on the inlet end ring 2. A height adjustment component is provided on the first base 4 or the second base 5 to adjust the height of the first base 4 or the second base 5, so that the synchronization device 3 can be adapted to different double-car tippers.

[0027] In one possible implementation, the first base 4 has a convex cross-section, and the second base 5 has a concave cross-section, with the convex part of the first base 4 matching the concave part of the second base 5. Specifically, both the first base 4 and the second base 5 are cuboid in shape, with a rectangular protrusion on one side of the first base 4 and a matching rectangular groove on the side of the second base 5 opposite to the rectangular protrusion.

[0028] To adjust the height of the first base 4 and the second base 5, the height adjustment assembly includes a pad 71 and a bolt 72. The pad 71 matches the first base 4 or the second base 5, and the bolt 72 fixes the pad 71 to the first base 4 or the second base 5.

[0029] Specifically, both the first base 4 and the second base 5 are equipped with height adjustment components.

[0030] The first base 4 includes a first connecting part 41 and a first fixing part 42. The first connecting part 41 engages with the contact surface of the second base 5. The pad 71 is disposed between the first connecting part 41 and the first fixing part 42. The first fixing part 42 is fixedly connected to the vehicle exit ring 1. In this embodiment, the first connecting part 41 is convex, and the first fixing part 42 and the pad 71 are rectangular. The first connecting part 41, the pad 71, and the first fixing part 42 are all provided with threaded holes that match the bolts 72.

[0031] The second base 5 includes a second connecting part 51 and a second fixing part 52. The second connecting part 51 engages with the contact surface of the first base 4. The pad 71 is disposed between the second connecting part 51 and the second fixing part 52. The second fixing part 52 is fixedly connected to the vehicle entry end ring 2. In this embodiment, the second connecting part 51 is U-shaped, and the second fixing part 52 and the pad 71 are rectangular. The second connecting part 51, the pad 71, and the second fixing part 52 are all provided with threaded holes that match the bolts 72.

[0032] To increase the structural strength of the first base 4, positioning blocks 6 are provided on both sides of the first base 4. The bottom of the positioning block 6 is fixedly connected to the exit end ring 1, and the inner side of the positioning block 6 is in contact with the first base 4. In this embodiment, the positioning block 6 is cuboid in shape, and the positioning block 6 and the first base 4 can be welded together.

[0033] Similarly, in order to increase the structural strength of the second base 5, positioning blocks 6 are provided on both sides of the second base 5. The bottom of the positioning block 6 is fixedly connected to the vehicle entry end ring 2, and the inner side of the positioning block 6 is in contact with the second base 5.

[0034] The working principle of this utility model:

[0035] In use, the height of the first base 4 and the second base 5 can be adjusted by adjusting the height or number of pads 71, so that when the first base 4 and the second base 5 are engaged, the height between them is consistent with the gap between the end plate body of the exit end ring 1 and the inlet end ring 2. When the tipper rotates, the first connecting part 41 and the second connecting part 51 engage with each other, and they rotate synchronously. During this process, the positioning blocks 6 located on both sides of the first base 4 and the second base 5 increase the structural strength of the first base 4 and the second base 5, preventing the bolts 72 from loosening.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
