The fixed sliding seat 531 and the adjustable sliding seat 533 are both L-shaped plates, and through holes (one of which is a waist-shaped hole) are respectively formed in the two side plates, and are fixed by the lateral fixing bolts 536 to prevent the adjustable sliding seat 533 from swinging laterally. The fixed sliding seat 531 is fixedly connected with one end of the chassis 110 of the flatcar body 100 through an L-shaped mounting rib plate 532, and the adjustable sliding seat 533 is fixedly connected with the pulley seat 521. One end of the tensioning adjusting screw 534 is fixed on the adjustable sliding seat 533, and the other end passes through the through hole on the fixed sliding seat 531 to be in threaded connection with the locking nut 535. By screwing the locking nut 535, the tension adjusting screw 534 rotates and drives the adjustable sliding seat 533 to move, so as to adjust the distance between the fixed pulley 522 and the chain wheel 512, and change the tension.
The canopy body locking device 600 is used to lock two movable canopy bodies 400 to two end wall assemblies 200, and the specific structure thereof is shown in embodiment 2.
Other parts not mentioned, such as bogies, brakes, container locking devices, etc., adopt the mature structure of existing railway wagons.
The loading process of the box wagon will be described below by taking the loading of the cargo requiring rain and snow protection as an example.
Before loading, both of the movable shelves 400 are in a closed state, fig. 11 (a).
When loading, the first movable canopy 400 is first unlocked and pushed open, so that the corresponding half floor is opened, and a first batch of goods 700 is loaded thereon, as shown in fig. 11 (b).
Then, the second movable trunk 400 is unlocked and both the movable trunks 400 are pushed onto half of the floor loaded with the cargo 700, leaving the other half of the floor open, and a second batch of cargo 700 is loaded thereon, see fig. 11 (c).
After the loading is completed, the second movable housing 400 is pushed back to the closed position, and the ends of the two movable housings 400 are locked to the corresponding end wall assemblies 200, thereby completing the loading, as shown in fig. 11 (d).
The movable shed bodies 400 or the movable shed bodies and the end wall assembly 200 are sealed and rainproof through corresponding sealing strips.
The process of unloading the cargo is analogized, and the description is omitted.
The multifunctional railway box wagon has the functions of a box wagon and a shared flat wagon, has the rainproof function on one hand, avoids the corrosion of goods due to sunshine, rain and snow, and can transport goods which are afraid of sunshine, rain and snow; on the other hand, the box-type wagon can be loaded and unloaded from the side surface and the roof, so that multipurpose transportation of machine equipment, boxed goods, military equipment, containers and the like is realized, and the application range of the box wagon is expanded; meanwhile, goods which need rain protection, sun protection, rain protection and snow protection and need to be hoisted from the top can be transported, such as certain steel plates, cables, electromechanical equipment and the like. Therefore, the transportation advantages of the boxcar and the flat car are fully exerted, the idle time of the car is reduced, the return trip of the empty car and the invalid energy consumption are reduced, and the railway transportation efficiency and the transportation economy are improved.
