DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] The specific embodiment is a novel motor train traction rod, and a structural schematic view thereof is shown in Figure 1 、 Figure 2 、 Figure 3 , which comprises a traction rod body 1 and a limiting assembly 2. The traction rod body 1 is provided with a connecting ring 5 at both ends. The side surface of the connecting ring 5 is in contact with the limiting assembly 2. The limiting assembly 2 has multiple groups. A recess hole 4 is formed in the middle position of the side surface of the connecting ring 5 away from the traction rod body 1. A pipe body 12 is movably clamped on the connecting ring 5. A rubber piece 6 is fixedly installed inside the pipe body 12. A traction rod column 7 is installed through the middle position of the rubber piece 6. A plug hole 8 is formed at both ends of the traction rod column 7. A traction rod piece 3 is installed at the middle position of both ends of the traction rod column 7. A connecting hole 10 is formed in the middle position of the traction rod piece 3. A threaded hole 9 is formed in the middle position of the side surface of the pipe body 12. A bolt 11 is threadedly matched with the threaded hole 9. The bolt 11 is slidably matched with the recess hole 4. In actual use of the traction rod, the limiting assembly 2 is installed on both sides of the connecting ring 5. Then the traction rod piece 3 and the connecting hole 10 are connected with the vehicle body and other components such as the bogie. When the motor train is running, the connection is realized through the traction rod. The rubber piece 6 plays a role of displacement compensation and shock absorption and buffering. When the rubber piece 6 is cracked, the limiting assembly 2 blocks the rubber piece 6 and the traction rod column 7, preventing the rubber piece 6 from being pulled out when it is cracked (when the rubber piece 6 is cracked, the connecting force between the traction rod column 7 and the pipe body 12 is weakened, and the traction rod column 7 and the rubber piece 6 are easily pulled out). Under the action of traction force, the traction rod column 7 is pulled out (for example Figure 1 When the rubber piece 6 on the right side in the middle is cracked, under the action of traction force, the traction rod piece 3 drives the traction rod column 7 to bear upward force. The upper limiting assembly 2 also bears upward force. However, the lower limiting assembly 2 is in abutment with the side surface of the connecting ring 5, so that the traction rod column 7 and the rubber piece 6 cannot be pulled out by the upward force, thereby ensuring that the traction rod is not pulled out and safety is ensured).

[0026] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the limiting assembly 2 includes a limiting plate 201, a circular hole 202 is formed in the middle of the limiting plate 201, the circular hole 202 is matched with the pull rod column 7, the limiting plate 201 is slidingly connected with a vertical rod 204, a circular rod 203 is installed on the upper end of the vertical rod 204, the circular rod 203 is in contact with the upper surface of the limiting plate 201, an extrusion plate 206 is connected with the lower end of the vertical rod 204, a spring 205 is sleeved outside the vertical rod 204, the upper end of the spring 205 is fixedly installed inside the limiting plate 201, the lower end of the spring 205 is fixedly installed on the upper surface of the extrusion plate 206, an insertion rod 207 is installed on the middle of the lower surface of the extrusion plate 206, the insertion rod 207 is slidingly matched with the limiting plate 201, the insertion rod 207 is slidingly matched with the insertion hole 8, the circular rod 203 is pulled upward, the circular rod 203 moves upward to drive the vertical rod 204 to move upward, the vertical rod 204 moves upward to drive the extrusion plate 206 to move upward, the extrusion plate 206 moves upward to drive the compression spring 205, the extrusion plate 206 moves upward to drive the insertion rod 207 to move upward, then the limiting plate 201 and the circular hole 202 are aligned with the pull rod column 7 and are clamped in, then the circular rod 203 is loosened, the insertion rod 207 is inserted into the insertion hole 8 under the rebounding action of the spring 205, the installation of the limiting assembly 2 is completed, when the rubber part 6 is cracked, the limiting plate 201 is fixedly connected between the insertion hole 8 at both ends of the pull rod column 7, the rubber part 6 and the pull rod column 7 are limited, and the rubber part 6 and the pull rod column 7 are prevented from being pulled out.

[0027] Working principle: when the traction pull rod is actually used, the limiting assembly 2 is installed on both sides of the connecting ring 5, then the pull rod part 3 and the connecting hole 10 are connected with the vehicle body and other components such as the bogie, during the running of the motor train, the connection is realized through the traction pull rod, the displacement compensation and shock absorption are realized through the rubber part 6, when the rubber part 6 is cracked, the limiting assembly 2 blocks the rubber part 6 and the pull rod column 7, and prevents the rubber part 6 from being cracked (when the rubber part 6 is cracked, the connecting force between the pull rod column 7 and the pipe body 12 is weakened, and the pull rod column 7 and the rubber part 6 are easily pulled out), under the action of the traction force, the pull rod column 7 is pulled out (for example Figure 1 When the rubber part 6 on the right side in the middle is cracked, under the action of the traction force, the pull rod part 3 drives the pull rod column 7 to bear upward force, the upper limiting assembly 2 also bears upward force, but the lower limiting assembly 2 abuts against the side surface of the connecting ring 5, so that the pull rod column 7 and the rubber part 6 cannot be pulled out by the upward force, thereby ensuring that the traction pull rod is not pulled out and safety is ensured);

[0028] The installation mode of the limiting assembly 2 is that the circular rod 203 is pulled upward, the circular rod 203 moves upward to drive the vertical rod 204 to move upward, the vertical rod 204 moves upward to drive the extrusion plate 206 to move upward, the extrusion plate 206 moves upward to drive the compression spring 205, the extrusion plate 206 moves upward to drive the insertion rod 207 to move upward, then the limiting plate 201 and the circular hole 202 are aligned with the pull rod column 7 and are clamped in, then the circular rod 203 is loosened, the insertion rod 207 is inserted into the insertion hole 8 under the rebounding action of the spring 205, the installation of the limiting assembly 2 is completed, when the rubber part 6 cracks, the limiting plate 201 is fixedly connected between the insertion hole 8 at the two ends of the pull rod column 7, the rubber part 6 and the pull rod column 7 are limited, the rubber part 6 and the pull rod column 7 are prevented from being pulled out, through the setting of the limiting assembly 2, the limiting of the rubber part 6 is realized, when the rubber part 6 cracks, the rubber part 6 and the pull rod column 7 can be prevented from falling out of the pull rod, the situation that the high-speed train traction system cannot be normally used is avoided, safety is ensured, and the limiting assembly 2 is elastically installed, when the rubber part 6 needs to be replaced, the limiting assembly 2 is convenient to disassemble, and the practicability is improved.
