Abstract

The utility provides a safety anti-theft device for railway freight, which uses a Janney coupler in a railway lorry box to control a lorry box door, which is simple in structure, flexible and convenient to use, low in production cost and is a perfect safety anti-theft device.

Description

The railway freight safety theftproof device

The utility model belongs to railway freight railway carriage annex.

Railway freight is one of important Shipping Method of China, because its carrying capacity is big, the moving velocity height generally is not subjected to the restriction of climatic conditions in the operational process, be suitable for the long-distance transport of large cargo, so speed of development is very fast.High speed development along with national economy and urban construction, freight traffic volume also heightens thereupon, the train transportation volume is big but because of every time, the Shi Douxian that generally conveys goods is divided in institute's fortune article in each railway carriage and locks, again each truck body is connected the back operation, only several people of escort personnel, the lawless person of many loving ease and hating work is just stealing the railway transportation goods as the way to pile up more money in recent years, they take advantage of the winding more speed of a motor vehicle of travelling and turn of goods train when slow, climb up train, open the railway carriage door lock, steal without restraint, only this item, railway interests all can take a bath every year, although public security department has strengthened hitting dynamics, engineering department locks at body door and has thought many improvement ways, but produces little effect, and its one of the main reasons is exactly that freight chamber door lock is easily opened by the offender, caused opportunity to their theft virtually, therefore needed to improve.

The purpose of this utility model is to make the railway freight railway carriage when operation, and body door can not be opened, thereby has protected the safe antitheft transportation of goods and materials.

The technical solution of the utility model as shown in Figure 1, truck body 1 has body door 7 on both sides, floor below at truck body 1 is fixed with cross cross bar 4, cross cross bar 4 is to be welded by major axis and minor axis, 2 stocks 3 flexibly connect with the minor axis two ends of cross cross bar 4 respectively, stock 3 other ends directly reach the Zhan Tianyou hook 2 at truck body 1 two ends, pass body and arrive hook 2 cores.Stock 3 does not stretch out core at closing time, the minor axis of cross cross bar 4 is horizontal at this moment, the major axis two ends of cross cross bar 4 are equipped with finishing bevel gear cuter 5 and cooperate with the lower end finishing bevel gear cuter 5 of 6 of buckles, buckle 6 is that one side downhand welding of angle steel is formed one on axle, and buckle 6 is installed in the doorframe limit near body door 7.When truck body 1 with after another truck body is connected, the core stock 3 of Zhan Tianyou hook 2 is by jacking, at this moment the minor axis of cross cross bar 4 is pushed into and the carriage bottom plate upright position, the finishing bevel gear cuter 5 at cross cross bar 4 major axis two ends has rotated 90 degree simultaneously, the finishing bevel gear cuter 5 that drives on 6 of the buckles rotates 90 degree, buckle 6 promptly fastens body door 7 like this, and this moment, body door 7 all can't be opened in any case.After goods is transported to the destination, must throw off the two ends truck body, just can open lorry chamber door 7.

Illustrate:

Fig. 1, railway freight safety theftproof device scheme drawing.

1, truck body; 2, Zhan Tianyou hook; 3, stock; 4, cross cross bar; 5, finishing bevel gear cuter; 6, buckle; 7, body door.

The utility model utilized the Zhan Tianyou hook be used for control that the lorry chamber door opens, when when transforming the used car case, if Zhan Tianyou hook 2 passes body punching difficulty, also the termination of stock 3 can be curved the U font, walk around body, enter hook 2 cores, still can reach effect same.To buckle 6 can also above the door, below the buckle of additional long hook, on the upper and lower edge that directly is hooked to.Also can add the another side of a cover cross cross bar 4 at door in addition, it is dead to form comprehensively detaining up and down of door like this, reaches safe and reliable purpose.

The part of the utility model under truck body 1 base plate is all with protective cover protection, in order to avoid destroyed or get rusty etc.Service life is identical with truck body.

The utility model can be pacified two extension springs on the minor axis of cross cross bar 4, be connected with the base plate of truck body 1, not at closing time, minor axis is remained on the level attitude.In addition, convenient during for needs driving chamber door, stretch out 5 one sections of finishing bevel gear cuters in the major axis termination of cross cross bar 4, make square or polygon, so that serviceable tool is opened body door.

The utility model is simple in structure, use is light flexibly, productive costs is low, and it is reliably antitheft to be perfectly safe in the shipment process.
