Abstract
The utility model discloses a flexible hook lift chain of a torpedo tank car. The flexible hook lift chain structurally comprises the hook lift chain body formed by sleeving of a plurality of chain rings, and one end of the hook lift chain body is connected with a hook lift rod on a carriage while the other end of the same is connected with a car hook; two ends of each chain ring open and close and are respectively provided with threaded holes in a penetratingly manner, and the two ends of the chain rings are connected together through bolts and fastening nuts. By the arrangement, flexibility of the chain is strengthened, and situations of stretch bending of the hook lift rod and automatic unlocking of the car hook can be prevented when the car passes through routes small in curve radius.
Description
Technical field
The utility model relates to a kind of chain of carrying, and specifically a kind of torpedo tank car flexible hook is carried chain.
Background technique
Along with the operation of the large blast furnace of China's smelter, large converter, it is the traffic tool that transport molten iron that smelter railway transport adopts torpedo tank car one after another at present.But be subject to the restriction of plant area's scale, Ji steel blast furnace, converter dense distribution, railway track zigzag 18 are curved, and sweep is little, and to torpedo tank car, transportation has brought very large difficulty.At vehicle, usually cause the situation of hook shadoof stretch bending, hitch auto-unlocking, the greatly safety of menace's railway transport during by curve.
Summary of the invention
The purpose of this utility model is to provide a kind of torpedo tank car flexible hook to carry chain, and this hook is carried chain and strengthened chain flexibility degree, causes the situation of hook shadoof stretch bending, hitch auto-unlocking in the time of preventing vehicle by the little circuit of sweep.
The technical scheme in the invention for solving the technical problem is: torpedo tank car flexible hook is carried chain, and its structure comprises that by a plurality of chain links, being socketed the hook forming carries chain, and described hook is carried chain one end and is connected with the hook shadoof on box body, and the other end is connected with hitch; The two ends folding of described chain link, the two ends of chain link folding are respectively equipped with the tapped hole running through, and by bolt and tightening nut, the two ends of chain link are linked together.
The corresponding inner side, two ends of described chain link is respectively arranged with a groove.
Described hook is carried the chain link that chain is 50mm by three diameters and is socketed.
Described chain link is Elastic Steel material.
The beneficial effects of the utility model are:
1, due to hook, to carry chain be to be socketed by three chain links, strengthened hook and carried chain flexibility degree, when torpedo tank car can not cause hook when by small curve radius circuit, do not carry chain stretch bending hook shadoof when horizontal, causes hitch auto-unlocking, causes the saunter generation of car accident of vehicle.
2, the two ends due to each chain link are to be flexibly connected by bolt, after tightening nut demounting bolt, can press one end of chain link, and the opening of chain link is opened, and are convenient to being nested and overhauling of each chain link.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model the second embodiment's structural representation;
Fig. 3 is the enlarged view of chain ring interface.
Fig. 4 is use phase diagram of the present utility model.
In figure: 1 chain link, 2 bolts, 3 tightening nuts, 4 grooves, 5 hitches, 6 box bodies, 7 hooks are carried chain.
Embodiment
With reference to Figure of description, torpedo tank car flexible hook of the present utility model being carried to chain is described in detail below.
Embodiment one: as shown in the figure, torpedo tank car flexible hook of the present utility model is carried chain, and its structure comprises that by a plurality of chain links 1, being socketed the hook forming carries chain 7, and described hook is carried chain 7 one end and is connected with the hook shadoof on box body 6, and the other end is connected with hitch 5; The two ends folding of described chain link 1, the two ends of chain link 1 folding are respectively equipped with the tapped hole running through, and by bolt 2 and tightening nut 3, the two ends of chain link 1 are linked together, tightening nut 3 can be by more fastening the linking together in the two ends of chain link 1, prevents that external force is loosening or open by the interface end of chain link.The loose surplus design that hook is carried chain 7 is between 30-50mm.
Embodiment two: as shown in Figure 2, the corresponding inner side, two ends of described chain link 1 is respectively arranged with a groove 4, when cover hangs over the lower shot of a cable ring swing of chain link groove 4, can better control hook and put forward the loose surplus of chain, prevent that torpedo tank car from can not cause hook to carry chain stretch bending hook shadoof when horizontal when by small curve radius circuit, causes hitch auto-unlocking.
Described hook is proposed chain link 1 socket that chain 7 is 50mm by three diameters.
Described chain link 1 is Elastic Steel material, when cover chain ring 1 or field-strip, tightening nut 3 is backed out, then bolt 2 is separated with chain link 1, because chain link 1 is Elastic Steel material, more can save time, timesaving presses chain link 1 jointing, is convenient to being inserted in or taking out of lower pitch chain ring.
Hook of the present utility model is carried chain and has been strengthened chain flexibility degree, causes the situation of hook shadoof stretch bending, hitch auto-unlocking in the time of preventing vehicle by the little circuit of sweep, causes the saunter generation of car accident of vehicle, has strengthened torpedo tank car Security in transit.
