Multiple stop blocks are automatically adjusted to the proper posture at different positions. The mechanism is simple and reliable, with low failure rate and easy maintenance.

[0019] (2) Different from the traditional one-way stop mechanism that relies on the deadweight of the stop block, the wheelset can reverse at a specific position to meet the special needs of reverse transportation when abnormalities occur during operation.

[0027] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1 to 4As shown, a wheelset stop mechanism in the embodiment of the first aspect of the utility model comprises a stop block A1, a support leg A2, a pin A3, a stop block B4, a pin B5, a support leg B6, a lever A7, a pin C8, a lever B9, a lever assembly, a pin D12 and a stop block C13; the pin A3, the pin B5 and the pin C8 are rotatably arranged on the lift 14 from left to right in sequence, the pin D12 is rotatably arranged on the fixed platform 15, the stop block A1 is arranged on the pin A3, the support leg A2 is mounted on the lower part of the stop block A1, the stop block B4 is arranged on the pin B5, the support leg B6 is mounted on the lower part of the stop block B4, the lever A7 and the lever B9 extending on both sides are mounted on the pin C8, and the stop block C13 and the lever assembly are both mounted on the pin D12 ; When the elevator 14 is located at the lower limit position, the stop block A1 is in a horizontal posture, the stop block B4 is in a horizontal posture, and the stop block C13 is in a stop posture. At this time, the lever A7 abuts against the end of the stop block A1, and the lever B9 is out of contact with the lever assembly; when the elevator 14 is in the lifting process, the stop block A1 is in a stop posture, the stop block B4 is in a stop posture, and the stop block C13 is in a stop posture. At this time, the lever A7 abuts against the end of the stop block A1, and the lever B9 abuts against the end of the lever assembly; when the elevator 14 is in the upper limit position, the stop block A1 is in a stop posture, the stop block B4 is in a horizontal posture, and the stop block C13 is in a horizontal posture. At this time, the lever A7 abuts against the end of the stop block A1, and the lever B9 abuts against the end of the lever assembly.

[0030] In the above embodiment, it should be noted that when in use, during the lifting process of the elevator 14, the stop block A1 is in a stopping state due to the action of gravity, and the wheelset cannot pass through the elevator 14 to the left. When the elevator 14 is completely dropped, the bottom of the stop block A1 is pressed against the bottom of the pit, driving the stop block A1 to rotate to a horizontal posture, and the wheelset can pass freely; during the lifting process of the elevator 14, the stop block B4 is in a stopping posture due to gravity, and the wheelset cannot pass to the right. After the elevator 14 is fully raised, the lever is triggered, and the lever A7 pushes the stop block B4 flat, and the wheelset can pass freely and be transferred to the fixed platform 15; in the natural state, the stop block C13 is in a stopping posture due to gravity, and the wheelset cannot pass from right to left (anti-falling). After the elevator 14 is fully raised, the lever is triggered, and the lever C11 drives the stop mechanism to rotate to a horizontal posture, and the wheelset can pass freely.

[0031] This product solves the problem of reverse rolling when transporting different equipment parts of the wheelset. By designing a mechanical interlocking mechanism, it is more convenient to transport the wheelset between the elevator and the fixed platform. Automatic stopping and automatic release can be achieved during the wheelset transportation process without manual intervention.

[0032] The technical effect achieved by the above embodiment is: through a wheel set stop mechanism of this embodiment, a mechanical interlocking structure is adopted, and the linkage effect is triggered by gravity and the lifting of the platform, and multiple stop blocks are automatically adjusted to the proper posture at different positions. The mechanism is simple and reliable, with a low failure rate and convenient maintenance. Different from the traditional mechanism that relies on the deadweight of the stop block to stop in one direction, the wheel set can flow in the reverse direction at a specific position, meeting the special needs of reverse transportation when abnormalities occur during the operation. When the elevator is at the bottom, the two stop blocks on the elevator are released, the flatness on the elevator is good, and other operating trolleys can pass through the elevator smoothly. When the elevator is at the bottom, the two stop blocks on the elevator are released, and the wheelset can be pushed freely. During the lifting process, the two stop blocks on the elevator automatically stand up due to gravity to prevent the wheelset from falling. After the elevator rises to the highest point, the interlocking mechanism is triggered, and only the leftmost stop block stands up to prevent falling, and the wheelset can be freely transferred between the lifting platform. After the elevator descends from the highest point, the stop block of the fixed platform will immediately stand up to prevent falling. The functions are reasonable and meet the needs of daily maintenance work.

[0037] The technical effect achieved by the above embodiment is: the lever extension rod 10 and the lever C11 are fixed with bolts through the long hole to achieve the effect of adjusting the length; after the lift 14 is fully raised, the lever B9 contacts the lever extension rod 10, the lever B9 drives the lever A7 to rotate, the lever A7 lifts the stop block B4 to a horizontal posture, the lever extension rod 10 drives the lever C11 and the pin D12 to rotate, and then drives the stop block C13 to rotate to a horizontal posture.
