Description

Technical Field

[0001] The invention relates to the field of railway transportation, and in particular to a boarding auxiliary device suitable for railway flat cars. Background Art

[0002] Flatcar is a type of railway freight car. When shunting container freight trains during railway transportation operations, a flatcar needs to be hung at the front of the train as a means of boarding for the shunting commander. After the operation is completed, the flatcar needs to be disassembled from the container freight train.

[0003] Flat cars have no cover, and side panels are set on the four sides, of which two side panels are equipped with side doors for convenient loading and unloading of goods. Flat cars are mainly used to transport bulk goods such as coal, ore, mining and construction materials, wood, steel, etc., and can also be used to transport light mechanical equipment. If the goods are covered with waterproof canvas or other awnings, they can replace boxcars to transport goods that are afraid of rain. Therefore, flat cars have great versatility and are the largest in the composition of trucks. At present, there are about 300,000 flat cars on the road, accounting for more than 50% of the total number of trucks.

[0004] The side of the flat car is usually equipped with pedals and handrails for workers to fix their positions. However, due to the structural limitations of the flat car, only one level of pedal and one handrail can be set, which poses certain risks during operation. On the one hand, the conventional stepping method has the disadvantages of repeated reactive work and waste of manpower and machine power; on the other hand, in the case of tight railway lines, the difficulty of scheduling operations increases and the risk factor of shunting operations also increases accordingly.

[0005] With the development of the logistics industry, production and transportation are at full capacity, and container freight trains have been developed due to their low price and safety advantages. With the existing personnel and equipment remaining unchanged, the difficulty of railway transportation operations has increased significantly, and the sharp increase in the number of flat cars has also increased the workload. Frequent boarding has also increased the risk factor during operations, threatening the safety of operators while also affecting work efficiency, resulting in slower boarding inspection or loading and unloading speeds. Summary of the invention

[0006] The purpose of the present invention is to provide a railway flat car boarding assistance device, which can improve the working efficiency, shorten the parking time and effectively relieve the line pressure.

[0007] The present invention discloses a railway flat car boarding auxiliary device, which is vertically arranged on a flat car boarding ladder and comprises a fixed frame, a movable buckle and a pedal part, wherein the fixed frame is rectangular, a fixed rod is arranged inside the fixed frame, and the outside of the frame on the opposite side is connected to the pedal part;

[0008] The movable buckle is composed of a cross bar, sleeves fixed at both ends of the cross bar, and an L-shaped buckle movably connected to the cross bar, and the sleeve is nested on the outside of the two rods in the vertical direction of the fixed frame;

[0009] The pedal part consists of a pedal, a pedal clip and a positioning groove. The pedal is a horizontally arranged rectangular plate whose edge is fixedly connected to a fixed frame. A pedal clip is arranged on one edge of the pedal away from the fixed frame. The pedal clip is step-shaped and starts to descend from the contact position with the pedal. The positioning groove is a U-shaped groove vertically fixed on the pedal. The notch of the U-shaped groove faces in the opposite direction to the pedal clip. The U-shaped groove is fixedly connected to the pedal through a plate extending from one side edge.

[0010] The fixing rod in the fixing frame is arranged in the horizontal direction, and the movable buckle is arranged below the fixing rod in the vertical direction, thereby expanding the moving range of the movable buckle and being applicable to railway flat cars of various structures.

[0011] Furthermore, the pedal is fixedly connected to the fixed frame through a connecting frame, and the connecting frame is composed of a main rod and four auxiliary rods. Two auxiliary rods are fixed at both ends of the main rod in a vertical direction and fixedly connected to the edge of the pedal. The midpoint of the main rod is used as the symmetrical point, and another two auxiliary rods are arranged in parallel in the opposite direction in the middle of the main rod and fixedly connected to the fixed rod.

[0012] Preferably, the two ends of the positioning groove are asymmetrical in length, and the longer side thereof extends in the vertical direction and is fixedly connected to the pedal, so as to be easily inserted into the original vertical rod of the railway flat car.

[0013] Preferably, in order to maintain the overall balance of the movable buckle, the cross bar is fixedly connected to the midpoint of the sleeve.

[0014] The present invention also discloses an auxiliary method for using the device to board a railway flat car, which comprises inserting the pedal clip into the original transverse pedal of the railway flat car so that the pedal is on the transverse pedal of the railway flat car, and clipping the positioning groove to the rods on both sides of the transverse pedal. At the same time, the movable clip is moved in the vertical direction so that the L-shaped clip is buckled onto the original handrail of the railway flat car. When boarding, the fixed rod is held and the pedal is stepped on to board the railway flat car.

[0015] The use of the climbing assist device shown in the present invention can effectively improve the safety of workers climbing flat cars. The device as a whole has many structures that can be held by hand, and workers can stand and climb more comfortably, which can ensure that workers can change postures and perform other operations in a climbing state. In addition, the device has a stable structure and is easy to disassemble and assemble. It is suitable for a variety of vehicle models and can be operated by one operator, which can effectively reduce the number of participants. In addition, the rapid disassembly and assembly of the device can improve work efficiency, save locomotive fuel consumption, and reduce the labor intensity of workers. Rapid operation can also effectively relieve line pressure and increase the speed of transportation and mobilization on railways. BRIEF DESCRIPTION OF THE DRAWINGS
