Abstract
The utility model relates to a door reinforcing device of a railway freight box car. The door reinforcing device is formed by a reinforcing plate (1), two hooked threaded rods (2) and two nuts (3), wherein one end of each hooked threaded rod (2) is provided with a hook (21), and the other end of each hooked threaded rod (2) is provided with threads (22). Two locking stoppers (12) are arranged on positions between hooked threaded rod holes (11) which are formed in the two ends of the reinforcing plate (1). The fixed ends of the locking stoppers (12) are connected with the reinforcing plate (1) into a whole, and the free ends of the locking stoppers (12) tilt towards the corresponding nuts (3) from the plate face on the same side of the reinforcing plate (1) respectively. After a car door is fastened through the door reinforcing device, the anti-loose effect of the nuts is good, the nuts will not automatically get loose, and safety performance is better. When the door reinforcing device is used, the nuts are fastened and then the two locking stoppers are squeezed down towards the two nuts and fix the two nuts respectively, and consequently the nuts are prevented from automatically getting loose. The door reinforcing device is more reasonable in structure, better in use effect and more beneficial to popularization and application, and further improves the safety of goods transportation of the railway freight box car.
Description
Technical field
The utility model relates to railway traffic attachment, is specifically related to a kind of covered truck door reinforcing device.
Background technology
The existing covered truck door reinforcing device consisting of reinforced plate and two hook-type screw rods has assembling and fixed installation is convenient, and pulley backplate both sides are stressed evenly, contributes to improve the advantage in the service life of pulley backplate, has been subject to universal and application widely.But its fastening nuts rear anticreep effect on hook-type screw rod is good not, box car nut in the process of operation easily gets loose, and has reduced the safety of box car transportation.
Summary of the invention
The purpose of this utility model is to provide a kind of fastening back nut anticreep railway freight box wagon device for reinforcing car door that fruit is good, safety is good.
Technical solution of the present utility model is: it is that the threaded hook-type screw rod of crotch other end tool and two nuts form by reinforced plate, two one end, reinforced plate two ends be provided with position between hook-type screw hole be provided with two wash upside down after for preventing that the anti-slow of the slow button of nut from only working as, each anti-slow fixed end of only working as is connected as a single entity with reinforced plate respectively, free end is respectively to the perk of the oblique nut direction of the same lateral plates direction of reinforced plate.
Technique effect of the present utility model is: the anticreep of the fastening back nut of this reinforcing device fruit is good, can automatically not get loose, and safety is better.During use, will after fastening nuts, two anti-slowly only ought be swept away and push nut to two nuts respectively, thereby reach the object that prevents that nut from getting loose automatically.Its structure is more reasonable, and result of use is better, further strengthens the safety of box car goods transport, is more conducive to universal and application.
accompanying drawing explanation
Fig. 1 is the utility model embodiment perspective view.
the specific embodiment
As shown in Figure 1, it is that hook-type screw rod 2 and two nuts 3 that crotch 21 other ends have a screw thread 22 form by reinforced plate 1, two one end, reinforced plate 1 two ends be provided with position between hook-type screw hole 11 be provided with two wash upside down after for preventing the anti-slow only when 12 of nut 3 slow buttons, each anti-slow only when 12 fixed end is connected as a single entity with reinforced plate 1 respectively, free end is respectively to the oblique nut 3 direction perks of the same lateral plates direction of reinforced plate 1.
Two limits of reinforced plate 1 long axis direction are bent to form stiffened edge 13 to being provided with anti-slow dorsal plate face direction of stopping when 12 respectively.After stiffened edge is set, can make reinforced plate 1 steel plate thickness used thinner, thereby make reinforced plate weight lighter.
Two hook-type screw holes 11 on reinforced plate 1 are respectively to slice off formation from reinforced plate 1, two anti-slow only when 12 is respectively that the homonymy that backward reinforced plate 1 is cut off from reinforced plate 1 in other limit except fixed end is bent to form, and each hook-type screw hole (11) bends from reinforced plate (1) anti-slow only when hole (14) is connected that open form becomes with corresponding anti-slow only work as (12) respectively.
Using method:
After items of freight entrucking finishes and covered truck door is closed, two hook-type screw rods 2 of reinforcing device are stretched into from pulley outer casing both sides, car door bottom respectively with one end of crotch, catch on the inner side edge in pulley road, car door bottom, after confirming to hook, two hook-type screw rods 2 are established in the hook-type screw hole 11 that threaded one end penetrates respectively reinforced plate 1, reinforced plate 1 is pressed on pulley backplate, installs nut 3.Two nuts 3 first carry out pretension, confirm after the correct cooperation of hook-type screw rod 2 buckle ends and slideway inner side and hook-type screw rod 2 and car door sheave and pulley backplate, fastening nut 3, reach and reasonably tighten after degree, one side plane of nut 3 hexagon planes is stopped after 12 over against anti-slow, anti-slow 12 free ends of only working as are pressed to reinforced plate 1 and push nut 3 and play position-limiting action, thereby reach the object that prevents that the multi-aspect vibrations in train operation from get loose nut 3, safe reliability is higher.Dismounting only only both can be removed the restriction to nut 3 when 12 free end levers up or pour anti-slow on reinforced plate 1 by anti-slow during reinforcing device in hole 14, then nut 3 was both backed out and reinforcing device can be disassembled, easy to operate.
