DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5, the utility model provides a technical solution: an electric flat car limit mechanism, including a base plate 1, a track 2, a mounting seat 3, a middle support plate 4, a locking bolt 5, a locking nut 6, a limit window 7, a middle spring telescopic rod 8, a buffer plate 9, a buffer pad 10, a side sleeve plate 11, a positioning plate 12, a positioning bolt 13, an extrusion bolt 14, a side support plate 15, a side spring telescopic rod 16 and a wheel blocking plate 17. Tracks 2 are installed on both sides of the top surface of the base plate 1. The center of the end of the base plate 1 is fixed with a mounting seat 3. The inner wall of the top groove of the mounting seat 3 is in contact with the bottom of the middle support plate 4. The bottom end of the side of the middle support plate 4 is fixedly installed with a locking bolt 5. The end of the locking bolt 5 is installed with a locking nut 6. The locking bolt 5 penetrates through the limit window 7. The limit window 7 is opened on the side of the vertical part of the mounting seat 3. The middle spring telescopic rod 8 is fixedly installed through the top of the middle support plate 4. The end of the middle spring telescopic rod 8 is installed with a buffer plate 9. The surface of the buffer plate 9 is installed with a buffer pad 10. The side sleeve plate 11 is fixed on the side of the vertical part of the mounting seat 3. The inner wall of the side sleeve plate 11 is in contact with one end of the positioning plate 12. The positioning bolt 13 is installed at the end of the side sleeve plate 11 in a threaded manner. The other end of the positioning plate 12 is in contact with the top of the track 2. The side support plate 15 is fixedly installed on the top surface of the positioning plate 12 above the track 2. The side spring telescopic rod 16 is fixedly installed on the side support plate 15. The end of the side spring telescopic rod 16 is installed with a wheel blocking plate 17.

[0024] In this example, the front view shape of the mounting seat 3 is a "丄" shape. The top groove of the mounting seat 3 is in sliding connection with the middle support plate 4. The above structural design enables the mounting seat 3 to be stably installed, and the middle support plate 4 can stably slide vertically to adjust the working height.

[0025] The locking bolts 5 are symmetrically distributed about the center of the mounting seat 3. The locking bolts 5 are in sliding connection with the limit window 7. The above structural design enables the middle support plate 4 to stably slide linearly along the limit window 7 with the locking bolts 5.

[0026] The middle spring telescopic rods 8 are symmetrically distributed about the buffer plate 9. The length of the buffer plate 9 is greater than the width of the middle support plate 4. The above structural design enables the buffer plate 9 and the buffer pad 10 to have a large-area contact with the side of the electric flat car, and cooperate with the middle spring telescopic rods 8 for stable buffer and limit.

[0027] The side sleeve plate 11 is in sliding connection with the positioning plate 12. The side sleeve plate 11 and the positioning plate 12 are both symmetrically distributed about the center of the mounting seat 3. The above structural design enables the positioning plate 12 to slide along the side sleeve plate 11 to adjust the horizontal working position and adapt to the tracks 2 with different spacings.

[0028] The end of the positioning plate 12 in contact with the top of the track 2 is set to a "J" shape. The width of the positioning plate 12 is greater than half of the width of the vertical part of the mounting seat 3. The above structural design enables the positioning plate 12 to be connected to the top of the track 2 and ensure the stability of the positioning plate 12.

[0029] The vertical part at the other end of the positioning plate 12 is threadedly installed with an extrusion bolt 14, and the end of the extrusion bolt 14 fits tightly against the top side of the track 2. The above structural design enables the extrusion bolt 14 to auxiliary fix the positioning plate 12 by squeezing the top side of the track 2.

[0030] The centers of the track 2, the side support plate 15, the side spring telescopic rod 16 and the wheel blocking plate 17 are on the same vertical plane. The wheel blocking plate 17 is provided with an arc surface at the end away from the side support plate 15, and the bottom end of the wheel blocking plate 17 is in contact with the top surface of the track 2. The above structural design enables the wheel blocking plate 17 to be centered and in contact with the bottom wheel of the electric flat car, thereby stably blocking the wheel.

[0031] Working principle: When using this device, first place the mounting seat 3 on the midpoint of the line connecting the two sides of the track 2 on the base plate 1, pull the positioning plate 12 away from the side plate 11 until the straight end of the positioning plate 12 is close to the positioning bolt 13, vertically lower the mounting seat 3, connect and fix the bottom end of the mounting seat 3 to the center of the top surface of the base plate 1, push the positioning plate 12 back toward the side plate 11, and until the end of the positioning plate 12 is as shown in the figure. Figure 4 As shown, it engages with the outer side of the top of the track 2, and the rotationally symmetrically distributed positioning bolts 13 squeeze the positioning plate 12 and the side sleeve plate 11 to fix it, and the rotating squeezing bolts 14 fit the outer side of the top of the track 2 to fix the entire device on both ends of the base plate 1;

[0032] Then pull the middle support plate 4, and the middle support plate 4 slides vertically along the limit window 7 with the locking bolt 5 until the middle spring telescopic rod 8, buffer plate 9 and buffer pad 10 on the top of the middle support plate 4 are aligned with the side of the electric flat car, and rotate the locking nut 6 to squeeze the vertical part of the mounting seat 3 to clamp the middle support plate 4 to complete the installation;

[0033] When the electric flat car travels to the end on the track 2, the buffer plate 9 and the buffer pad 10 fit closely with the side surface of the electric flat car over a large area. The electric flat car squeezes the middle spring telescopic rod 8 to compress it. The middle spring telescopic rod 8 uses its own elasticity to slow down and limit the body of the electric flat car. At the same time, the wheel blocking plate 17 contacts the bottom wheel of the electric flat car to prevent the wheel from continuing to move. The wheel pushes the wheel blocking plate 17 to compress the side spring telescopic rod 16. The side spring telescopic rod 16 uses its own elasticity to slow down and limit the wheel of the electric flat car. They cooperate with each other to achieve a better deceleration and limiting effect. This is the working principle of the electric flat car limiting mechanism.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
