Description

Technical Field

[0001] The present invention relates to the technical field of railway vehicle rollover prevention, and in particular to a railway vehicle rollover prevention device and an operation method thereof. Background Art

[0002] In the unloading system of the car dumper during the turnaround operation, the car transfer platform plays a vital role. It is responsible for accurately moving the railway car from the loaded car line to the empty car line. However, in the actual operation process, many factors lead to frequent rollover accidents of railway cars, which brings serious safety hazards to railway transportation.

[0003] When there is frozen material inside a railway vehicle, the uneven distribution of the material will cause the center of gravity of the vehicle to shift, greatly increasing the risk of rollover. If the moving platform stops too quickly during operation, the railway vehicle will not be able to remain stationary in a short period of time due to inertia, and it is very easy to tip over sideways. In addition, parking control at the trip terminal is crucial. Once a collision occurs without stopping, the strong impact force will instantly break the balance of the railway vehicle, resulting in a lateral rollover accident. Such accidents will not only cause damage to the vehicle and loss of cargo, but may also endanger the lives of on-site staff and seriously interfere with the normal order of railway transportation. Railway safety departments in many places attach great importance to this issue and have clearly required effective measures to solve the problem of railway vehicle rollovers, ensure the safety and stability of the moving platform operation, avoid the recurrence of accidents, and ensure the safe and efficient operation of the railway transportation system. Summary of the invention

[0004] In view of the technical problem of railway vehicle rollover during the lateral movement of the above-mentioned moving platform, a moving platform anti-railway vehicle rollover device and an operating method are provided. The device and method adopt an anti-railway vehicle rollover device installed on the side of the railway vehicle on the moving platform. When the empty car shunting locomotive pushes the car, the device lies down to pass the car. When the moving platform moves to the terminal of the empty car line, the device can be lifted up to block the side of the railway vehicle, thereby achieving the technical effect of preventing the railway vehicle from rolling over.

[0005] The technical means adopted by the present invention are as follows: A rolling stock transfer platform anti-rollover device for railway vehicles, comprising: a lower long hinge shaft seat, a swing vertical rod, a lower long hinge shaft, a cross bar, an upper short hinge shaft, a driving oil cylinder, and a driving oil cylinder hinge seat; The lower long hinge shaft seat is fixedly connected to the vehicle transfer platform and is used to transmit the lateral tipping force of the railway vehicle; The lower part of the swing upright rod is hinged to the lower long hinge shaft seat through the lower long hinge shaft; The cross bar is located on the upper part of the swing upright bar and is hinged with a plurality of swing upright bars through an upper short hinge shaft.

[0006] Furthermore, the front end of the driving oil cylinder is hinged to the first swing upright rod, and the rear end is hinged to the driving oil cylinder hinge seat, and the driving oil cylinder hinge seat is fixedly connected to the vehicle transfer platform.

[0007] Furthermore, a plurality of the swing uprights can be provided according to the length of the vehicle blocking member.

[0008] Furthermore, the cross bar can be lifted up through the upper short hinge shaft as the swing upright rod rotates; and the cross bar can be lowered through the upper short hinge shaft as the swing upright rod rotates.

[0009] Furthermore, the driving oil cylinder can drive the first swing upright rod to rotate around the lower long hinge shaft, thereby driving the cross bar and other swing upright rods to rise and fall.

[0010] An operating method of a railway vehicle rollover prevention device for a vehicle transfer platform comprises the following steps: Step 1: Before the transfer platform drives the railway vehicle to move to the empty vehicle line ground, the driving cylinder retracts, driving the first swing pole to rotate around the lower long hinge shaft and lift up, the first swing pole drives the cross bar to lift up through the upper short hinge shaft, and the cross bar drives the other swing poles to lift up; Step 2: When the railway vehicle rolls over, the crossbar blocks the carriage and transmits the force to the lower long hinge shaft through the crossbar and the swing vertical rod. The lower long hinge shaft seat transmits the lateral railway vehicle tipping load to the moving platform to prevent the railway vehicle from rolling over; Step 3: When the transfer platform drives the railway vehicle to the empty vehicle line, the driving cylinder is pushed out, driving the first swinging upright rod to rotate around the lower long hinge shaft and fall down. The first swinging upright rod drives the cross bar to fall through the upper short hinge shaft, and the cross bar drives other swinging upright rods to fall. When the cross bar falls below the big arm of the empty vehicle shunting locomotive, the anti-tipping device is prevented from interfering with the empty vehicle shunting locomotive. The empty vehicle shunting locomotive is started to push the railway vehicle out of the transfer platform.

[0011] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages: 1. The present invention provides a railway vehicle rollover prevention device and operation method for a moving platform. Through the cleverly designed lower long hinge shaft seat, swing upright, cross bar and driving cylinder and other components, a reliable protection system is formed during the operation of the moving platform. When the railway vehicle is facing the possibility of rollover due to frozen materials, the moving platform stopping too fast or the end of the stroke impact, the cross bar in the device can block the carriage in time, effectively prevent the railway vehicle from rolling over, and transmit the rollover force to the moving platform through the swing upright, the lower long hinge shaft and the hinge shaft seat, thereby ensuring the stability of the railway vehicle during transportation, greatly reducing the probability of rollover accidents, and ensuring the safe progress of transportation operations.

[0012] 2. The present invention provides a railway vehicle transfer platform anti-rollover device and operating method, which uses a driving cylinder as a power source. It only needs to control its extension and retraction to drive the first swing upright to rotate around the lower long hinge shaft, and then realize the lifting and lowering of the cross bar through the upper short hinge shaft, while linking other swing uprights to move synchronously. This simple and effective mechanical structure design makes the operation of the device extremely simple, without the need for a complex control system and excessive human intervention, reducing the difficulty of operation and labor intensity, and improving operating efficiency.

[0013] 3. The present invention provides a railway vehicle transfer platform anti-rollover device and operating method, which effectively prevents railway vehicles from rolling over, avoids damage to railway vehicles, transfer platforms and surrounding related equipment caused by rollover accidents, reduces the number of equipment maintenance times and the cost of replacing parts, reduces downtime caused by equipment failures, improves the overall reliability of the railway transportation system and the service life of equipment, and ensures the continuity and stability of railway transportation.

[0014] Based on the above reasons, the present invention can be widely promoted in the technical field of railway vehicle rollover prevention. BRIEF DESCRIPTION OF THE DRAWINGS
