Description
Technical Field
[0001] This utility model relates to a wheel-shielding device for railway flatcars. Background Technology
[0002] Currently, my country has very few dedicated rolling stock vehicles for railway transport. Various types of rolling stock are mainly transported by 60t and 70t shared flatcars (i.e., railway flatcars) with wooden floor structures. Regarding the reinforcement of rolling stock, some methods combine nailing and bracing with traction. Bracing mainly includes wooden bracing, plastic bracing with iron plating, and standard steel folding triangular bracing. Wooden bracing is secured to the flatcar's wooden floor using rivets, while plastic bracing with iron plating and standard steel folding triangular bracing are secured with steel nails. Such nailing methods easily damage the vehicle floor and reduce its service life.
[0003] A document reports a protective and reinforcing device for railway flatcars, comprising a fixed base, a guide rod, a transverse connecting base, and a fixed stop. The guide rod is arranged along the length of the underframe. There are at least two fixed bases, at least one of which is fixedly connected to the guide rod, while the others are slidably connected to the guide rod. The fixed bases are also detachably connected to a column insert. The transverse connecting base is substantially perpendicular to the length of the guide rod and is slidably connected to it. The fixed stop is disposed on the transverse connecting base and has at least one shielding surface that abuts against the wheels of the vehicles loaded on the railway flatcar for restraint and reinforcement. This protective and reinforcing device does not require nailing to the flatcar's wooden floor. Utility Model Content

The two first chain hoof rings 302 of each adjusting chain unit 3 are detachably connected to the fastening seats 125 of the two opposite blocking units 1.
[0041] like Figure 1 and Figure 5 As shown, there are multiple fiber optic chain units 4. The length of the fiber optic chain unit 4 is adjustable, with one end detachably connected to the fastening ring 126 and the other end detachably connected to the post insert 100 on the vehicle body 100. At least two fiber optic chain units 4 are provided corresponding to each blocking unit 1, and the ends of these two fiber optic chain units 4 connected to the post insert 110 are located on both sides of the corresponding blocking unit 1.
[0042] The fiber optic chain unit 4 is composed of a second chain hoof ring 401, multiple second chain links, a fastener 403, and multiple third chain links. Multiple second chain links are connected in sequence to form small chain links 402, and multiple third chain links are connected in sequence to form large chain links 404. One end of the second chain hoof ring 401 is connected to one end of the small chain link 402, and the other end of the second chain hoof ring 401 is connected to the fastening ring 126 of the blocking unit 1. Both ends of the fastener 403 are connected to the small chain link 402 and the large chain link 404, respectively. The end of the large chain link 404 away from the fastener 403 is detachably connected to the post insert 110 on the vehicle body 100.
