Abstract
The utility model relates to an instrument for lashing and securing train cars in train ferry. The utility model provides a safe, convenient and efficient pneumatic chain tensioner for technical problems to be solved. The utility model is mainly composed of a screw rod, sleeve barrels, a coupler body and a connecting shackle. The utility model is characterized in that the rod head of the screw rod is provided with a shoulder and a square column end head, through a rod hole on the front end of an outer sleeve, the rod body of the screw rod penetrates through the outer sleeve and is screwed with an internal thread on the front end of an inner sleeve which is sheathed on the outer sleeve; the front end of the outer sleeve is assembled with an end cover which blocks off the shoulder of the screw rod and the back end of the inner sleeve is fixedly connected with the connecting shackle; the bottom of the coupler body is fixedly connected with the barrel body of the outer sleeve. The utility model is used for the lashing and securing of the train cars in the train ferry.
Description
Technical field:
The utility model relates to the apparatus of railway carriage lashing and securing in the railway ferry.
Background technology
Tensioning colligation chain or be directly used in the car beam and the tensioning of D shape order ring when tensioner is used for railway ferry to the railway carriage colligation makes in the navigation compartment produce heel or can be fixed by the colligation chain safely when vertically moving; Simultaneously suffered force of inertia is delivered on the deck by the colligation chain.The chain tensioner of domestic and international purposes of the same race is rod-type tensioner or spiral tensioner at present, is M/C, by manpower the colligation chain is strained.This tensioning mode needs long operating time and bigger operational space, the operational space is comparatively narrow and small on the railway ferry, and the comparatively complicated effort of operating sequence, method of operation and enough common needs of staffing just can be finished colligation in about 2 hours routinely, because it is too many when colligation and releasing colligation operating cost, existing tensioner is inapplicable, becomes the bottleneck of the efficient operation of railway ferry.
The utility model content
The utility model technical issues that need to address provide a kind of safe, convenient, pneumatic chain tensioner efficiently.
The technical solution of the utility model mainly is made up of screw rod, sleeve, coupler body, joining shackle, it is characterized in that the spiral shell club head has a convex shoulder and a prismatic termination, the bar hole of screw rod shaft by the outer sleeve front end penetrates outer sleeve and spins with the negative thread that is enclosed within the inner sleeve front end in the outer sleeve, outer sleeve front end assembling end cap blocks the convex shoulder of screw rod, captiveing joint with joining shackle in the inner sleeve rear end, captives joint with the outer sleeve stack shell in the coupler body bottom.
The utility model during use, can adopt pneumatic pistol to drive screw rod owing to make prismatic end at screw rod one end, and it is relative with outer sleeve flexible to drive female inner sleeve by the screw rod rotation, reaches the technique effect that tightens up rapidly or loosen the colligation chain.
Description of drawings
Accompanying drawing is represented structural representation of the present utility model.
The specific embodiment
Implement best way of the present utility model below in conjunction with description of drawings:
The utility model mainly adopts screw rod, sleeve, coupler body, joining shackle to form, and the bar head of screw rod 4 is made a convex shoulder and a prismatic termination, hole, the cave running-fit of the external diameter of convex shoulder and outer sleeve 3 front ends, the prismatic termination of screw rod 4 and pneumatic pistol dop coupling; Screw rod 4 shafts penetrate outer sleeve 3 by the bar hole of outer sleeve 3 front ends, and spin with the negative thread that is enclosed within inner sleeve 5 front ends in the outer sleeve 3; Outer sleeve 3 front ends are established screw hole end cap 1 are installed, and end cap 1 central authorities are shaped on through hole, periphery has screw hole, and 3 ends of lid end cap 1 and outer sleeve adopt flathead screw 2 assemblings, and end cap 1 blocks the convex shoulder of screw rod 4; Captive joint with joining shackle 8 in inner sleeve 5 rear ends; Captive joint with outer sleeve 3 stack shells in coupler body 9 bottoms.Inner sleeve 5 barrel rear ends can establish a screw and equipped holding screw 6 is convenient to inside and outside sleeve contraction back lock nut.The pneumatic pistol of adapted coventional type when the utility model uses, 3500 rev/mins of rotating speeds, air pressure is 0.5～0.6Mpa, experiment shows that adopting the utility model to use can improve train colligation operating efficiency flexibly, reduce labour intensity, and in narrow and small operational space, can easily finish, safe and reliable, the single tensioning operating time is 5～10 seconds only, improve colligation efficient more than 4 times.
