Abstract

The utility model discloses a hand cord-tightening device for tightening a binding rope when loading and fixing goods in the train goods traffic. The hand cord-tightening device has a cord-tightening ratchet wheel 2, a force application lever handle 5, a four-bar cord clamping device 1 and a cord-tightening body 6 which is welded by a box body 6-1 and a hook 6-2 as a whole. The cord-tightening ratchet wheel is composed of a drum part, a baffle plate part and a ratchet wheel part with two ratchet pawls and two springs. The cord-tightening device has small volume, light weight, convenient operation and convenient carryover, the clamping force is not less than 2000KN, the binding is firm, and the binding speed is more than seven times than hand binding.

Description

Manual boomer

The utility model discloses a kind of manual boomer, belong in the goods transport, the instrument of tension bundle rope usefulness during goods loading and reinforcing.

In the railway freight, goods loading and reinforcing is fully by manual binding at present.Artificial hand is tied up, and bundle rope is difficult to tight jail, causes goods to be lightened restrictions in transit, and tarpaulin waves and comes off, the time have train operation accident to take place, jeopardize the railway transportation production safety.

The purpose of this utility model is a kind of simple and easy, binding tight jail and the high boomer of efficient of design.

The technical solution adopted in the utility model is a kind of manual boomer of design, and this boomer has a tight rope body by casing and hook-shaped hook solder together; One is made of ratchet portions, reel partial sum baffle part, is furnished with the tight rope ratchets of two band spring ratchets; A four-bar linkage rope gripper and an application of force lever handle that is linked together by conductor rope and ratchet.

The utility model volume is little, in light weight, easy and simple to handle, binding is firm, tight rope speed is fast.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:

This boomer has the rope gripper 1 of a four-bar linkage, the one end is welded with the clamp 9 of band thread form, its other end is with U-shaped plate 14 and 10 movable connections of conductor rope, and conductor rope 10 other ends pass square hole on the F face of tight rope body 6, and to insert knock hole 2-5 that reel 2-2 leaves again interior and weld; The a end of the rope gripper 1 of four-bar linkage and b end length ratio ao: ob=1: 2; The gripping power of clamp 9 is not less than 2000KN; A tight rope ratchet 2 is welded into by being processed into the ratchet 2-1 of control conductor rope 10 degrees of tightness, the reel 2-2 and the baffle plate 2-3 of control conductor rope 10 at the reel position of Steel Wire Coils conductor rope 10 usefulness with No. 45 steel; Be furnished with two on the ratchet 2 respectively and prevent its last ratchet that releases 7 and following ratchet 3, last ratchet 7 and following ratchet 3 have respectively be used for guaranteeing its manual after, still do not break away from ratchet 2, the spring 8 and 4 of tight rope continuously; Following ratchet 3 and lever handle 5 are linked together with Spring Card by the fix shaft 3-1 of tape spool shoulder, and spring 4 colludes respectively hangs ratchet 3 and lever handle 5 down; The fix shaft 7-1 of last ratchet 7 usefulness tape spools shoulder is contained in the tight rope body casing 6-1 and with Spring Card and locatees, and spring 8 is sleeved on the fix shaft 7-1, and the one end is stuck on the casing 6-1, and the other end is fitted in ratchet 7 bottoms; The fix shaft 2-4 that application of force lever handle 5 and ratchet 2 are takeed on by tape spool is contained on the tight rope body 6 and with Spring Card and locatees; A tight rope body 6 is an one by casing 6-1, hook-shaped hook 6-2 weldering; The casing 6-1 of tight rope body 6 by E, F, G, H, L totally 5 steel plates be welded into, two of E, G face and claim, have the assembly opening of fix shaft 2-4,7-1 on it, have the square hole that conductor rope 10 passes through on the F face, square hole top suit is used for the guide wheel 12 of conductor rope 10 anti-attritions location, F face below has and is used for the slotted hole that ratchet 7 inserts, and is beneficial to ratchet 7 and moves up and down; Be welded with hook-shaped hook 6-2 on the H face, its tensile strength is not less than 6000KN; Use fixedly elastic guard plate 13 of screw 11 on the L face of bottom surface, its shape and reel 6-2 are complementary, and are used to protect conductor rope 10 to be wrapped in reel 6-2 on request.These manual whole members of boomer are zinc-plated steel structure, and tight rope body 6 advancing sides adopt press forming.Ratchet 2 adopts No. 45 structural carbon steel machine-shaping.

Earlier the hook 6-2 of tight rope body 6 is hung over the truck body bottom during use, again reinforcing cord is pulled to the appropriate location, clamp reinforcing cord with rope gripper 1, pull lever handle 5 then downwards, making ratchet 3 drive ratchet 2 rotates, Steel Wire Coils rope 10 drives rope gripper 1 work of four-bar linkage, ratchet 7 locked ratchets 2 when upwards pulling lever handle 5, the reciprocal like this lever handle 5 of pulling is till tension binding reinforcing cord, reinforcing cord with tension lies on the car body again, pull ratchet 3 and 7, unload boomer.

Present embodiment weight is that gripping power is not less than 2000KN about 1 kilogram, and efficient is manual more than 7 times.
