Description
Technical Field
The invention relates to railway goods loading reinforcement, in particular to railway crawler goods transportation, and crawler goods can be fixed on a railway vehicle through the device, so that the displacement of the crawler goods during the running of a train is prevented.
Background
Along with the development of science and technology, crawler-type goods quantity increases to some extent, and people must fix crawler-type goods on rail vehicle steadily when using the rail transport crawler-type goods, when preventing that rail vehicle from linking up or braking, thereby crawler-type goods takes place the displacement and causes the damage even cause the personal danger to the goods. At present, the rail-mounted goods for railway transportation are generally reinforced by using pulling ropes, wheel blocks, special floors, rivets and the like.
The strength of the pulling ropes is limited, the stress of each pulling rope cannot be overlarge, a plurality of pulling ropes are needed when goods are fixed, and when the stress is not uniform, the pulling ropes are easy to break and damage the goods; and the pulling ropes are various in types, the proper pulling ropes are not easy to select, the reinforcing difficulty is high, the operation time is long, and the cost of the input manpower and material resources is overlarge.
The fender is applicable to the transportation of car more, and its area of contact with the goods is little, is applicable to elastic rubber tire more, if be used for steel crawler-type freight transportation, can damage fender and track.
The special floor is generally made of plain carbon steel, and the floor is provided with the convex grooves and the concave grooves, so that the special floor is more suitable for transportation of rubber tire type goods and can prevent the goods from moving when the rubber tire type goods are transported. If the special vehicle bottom plate is used for transporting crawler-type goods, the steel crawler can collide with the special vehicle bottom plate to be extruded, the vehicle bottom plate can be damaged while the crawler is damaged, and therefore the special vehicle bottom plate is not suitable for transporting the crawler-type goods; and the special floor has high manufacturing cost, difficult installation and large consumption of human resources.
The rivet reinforcement is put between track and railway vehicle timber apron with the rivet when the crawler-type goods loading, thereby the track is impressed the rivet in the timber apron and is fixed the goods after the loading, consolidates the harm greatly to the railway vehicle floor like this, and cost of maintenance is too high, and the rivet is difficult for following the timber apron and extracts after unloading moreover.
The reinforcing scheme is relatively backward, most of the reinforcing schemes are more suitable for tire type goods, and the reinforcing scheme is not suitable for crawler type goods. Even if the pulling rope and the rivet can meet the requirements of the track-mounted goods for railway transportation, the pulling rope and the rivet also can input large cost, consume a large amount of waste manpower and material resources, have relatively complex operation and are not beneficial to the track-mounted goods for railway transportation.
