Abstract

The utility model provides a cord tightening apparatus for baling cargo, which is of simple and compact structure, is of convenient operation and is of reliable operation. The utility model is composed of a U-shaped bracket (1), a cord fixing device, a cord tightening device, and a cranking handle. When cargo is baled, the cord tightening apparatus which is arranged between the two segments of a baling code horizontally moves through a moving clamp plate (9), and one segment of the baling code is tightened and is fixed between the moving clamp plate and a fixing clamp plate (8). A worm shaft (3) rotates, the other one segment of the baling code is wound around a rolling wheel (5), and the two segments of the baling code is tightened. The utility model utilizes the self locking performance of worm and gear drive to lock the tightened baling code.

Description

Cord tighting apparatus

The utility model belongs to bundling article, is in order to the boomer of bale cargo on a kind of shipping goods vehicle.

Freight is afraid of that the bundle rope is loosening most under steam, and goods is lost.The method of tradition bale cargo is, adopts the rope made of hemp (nylon rope is also arranged now), through the vehicle drag hook, manpower tension bundle rope, with goods bundling on lorry, the manpower bale cargo be one both painstaking, responsible again work.If it is loosening to occur the bundle rope in transit, often will missing package.Loosening to the bundle rope that occurs in transit, can't be tight again, can only take apart again and tie up, take a lot of work very much.Therefore, replacing manpower to tie up with machinery, has been the freight task of top priority.Nearly 2 years, several tight rope devices have appearred, on January 18th, 1989, the application number of patent gazette bulletin was 88219612.X, and the application number that name is called " rope tension unit ", July 18 nineteen ninety bulletin is that 89213315.5 denominations of invention are exactly wherein two kinds for " mechanical type pulling force binding device ".

The purpose of this utility model provides a kind of simple in structure, laborsaving reliable, easy to use, the boomer that cost is low, volume is little.

The technical solution of the utility model is: boomer is mounted between two sections bundle ropes (10), (11), and one section rope (10) is strained and fixed substantially, and another section rope (11) is locked with whole bundle rope tension by boomer.Boomer is made up of support, solid rope device, tight rope device, crank.

Support (1) is a U type body frame, and solid rope device is equipped with in the upper end in support (1).Gu rope device comprises strap (8), sliding clamp (9) and screw shaft (7), strap (8) is fixed on the upper end of support (1), adorning screw shaft (7) on the strap (8), sliding clamp (9) is being housed on the double-screw bolt of screw shaft (7).The termination of screw shaft is that the cubic hole of four directions and crank cooperates.

The tight rope device is contained in the bottom of support (1), and it comprises worm screw (3), worm gear (2), worm-wheel shaft (4), rolling wheel (5).Worm-wheel shaft (4) is contained on the biside plate of U type opening of support (1), on the worm-wheel shaft (4), coaxial rolling wheel (5) and the worm gear (2) adorned, rolling wheel (5) position is in the U type opening of support (1), and worm gear (2) position is outside the U type opening of support (1).Worm screw (3) is contained on the extension plate (6) of support (1), and worm screw (3) is meshed with worm gear (2).The end of worm screw (3) is the four directions, can cooperate with the cubic hole of crank.

With the matching used rope of boomer can be steel rope, also can be the high-strength nylon rope.

Example weight of the present utility model only is 1.7kg, if with 10 meters long, diameter is 5.3 millimeters a steel rope.40 meters long on a price and a dish, diameter is that 3 centimeters the rope made of hemp is suitable.Adopt this boomer, easy to operate, safe and reliable, self-locking property is good.

The drawing explanation:

Fig. 1 is the boomer structural representation.

Fig. 2 is the lateral plan of Fig. 1.

Fig. 3 is that boomer uses scheme drawing.

Embodiment: boomer is installed between two sections bundle ropes, after earlier one section bundle rope being strained by the lorry drag hook, rope is fixed between the strap (8) and ambulatory splint (9) of the anchor fitting of boomer, with crank rotating screw bolt axle (7), ambulatory splint (8) translation is advanced, just with rope clamp extremely between two clamping plate.Again with another section bundle rope on the drag hook of lorry opposite side, on rolling wheel (5), come rotary worm (3) again with crank, drive worm gear (2), rolling wheel (5) rotates, the bundle rope just with rolling wheel on rolling wheel (5), the tension of will restricting.Because worm drive has auto-lock function, therefore, the serving disengagement of can not skidding voluntarily.
