Abstract

The utility model discloses a mechanical device for loading, unloading, heaping and piling bagged and tied goods in groups. A tension pre-tightening mechanism is composed of a member of an upper power bearing board frame, a member of a lower power bearing board frame, a versatile fixed pulley, and wire rope. When the utility model is hoisted, the grouped goods are effectively positioned and controlled integrally. Goods are avoided from being dropped off in loading and unloading operation. The operation of loading, unloading, heaping and piling bagged and tied goods in groups is safely ensured. The utility model has the advantages of simple structure, easy fabrication, low cost, strong adaptability of the working operation to the bearing rope belt, small failure rate, etc.

Description

Bags, tied-up goods groups hoisting implement

The utility model is a kind of mechanical device that bag, bundled goods is carried out unitized cargo handling and stacking operation.

At the harbour, railway, field, inside and outside storehouse mechanical device that bag, bundled goods such as grain, sugar, ground caustic, cotton, fiber crops, chemical fertilizer, salt are carried out unitized cargo handling and stacking operation once had the utility model patent (patent No. 87215213.8) of " lifting device of bag, bundled goods " of my invention, certain advance and practicality are arranged, but structure is complicated, and forced stroke is not strong to the percentage elongation comformability of carrying rope band.

The purpose of this utility model be to provide a kind of structure simpler, make easilier, forced stroke is to the adaptable bag of the percentage elongation of carrying rope band, bundled goods suspender in groups.

Shown in attached Fig. 1 and 2: the utility model is by last load grillage parts, following load grillage parts, and universal fixed pulley and steel rope are formed the tension type pre-tightening mechanism.Four jiaos at last load grillage 6 are equipped with universal fixed pulley 3 respectively, and there are two knock holees 12 centre, also has a plurality of hook on hole 16, are installed with the convertible Automatic unhooking hook 9 of ordinary lifting hook 8 and weight in the hook on hole 16, and its upper end all is inserted with suspension hook lateral pin 17.Be fixed with locating piece 10 respectively at following load grillage 7 two ends, center fixed has load push rod 5, after load push rod 5 passes knock hole 12, and upper end fixed limit plate 4.After steel rope 2 passed universal fixed pulley 3 and suspension ring 1,11 middle parts that are fixed on positioning plate 4 were pricked with steel rope in its two ends.During lifting, under the effect of gravity, load grillage 7 compresses in advance the goods 15 on carrying rope band 14 in groups downwards under 5 bonded assemblys of tension force promotion load push rod of steel rope 2, and with last load grillage 6 between produce a forced stroke that separates, act on the goods 15 by suspension hook 8,9 and carrying rope band 14, goods after making in groups is in the whole positioning control of actv., like this, before the lifting, goods 15 just is subjected to integral pre-tightening, thereby avoided goods to do lifting at hoisting crane, luffing and dropping when rotatablely moving has guaranteed the safety lifting of goods.When putting down goods in the desired location, last load grillage 6 is being reused down certainly, close up with following load grillage 7, at last, drop on the locating piece 10, carrying rope band 14 loosens fully, convertible Automatic unhooking hook 9 upsets of weight, the woollen yarn knitting suspension ring 13 of carrying rope band 14 are deviate from from Automatic unhooking hook 9, adopted the method that symmetry breaks off relations that carrying rope band 14 is directly hung out from the goods bottom is heavy.When contacting, the large tracts of land of protrusion at first contacts stressed because the bag bag is with ground (or bag bag that pile is good), and it is very little to be under pressure in the groove of carrying rope band 14 after tying tight in bag bag bottom, so the carrying rope band is very easily extracted out from bag bag bottom.Goods can be realized automatic system of solutions pile fitly.

The utility model compared with the prior art, structure is simpler, it is easier to make, low cost of manufacture, forced stroke is strong to the comformability of carrying rope band percentage elongation, fault rate is little, loads and unloads more convenient, safety.

Accompanying drawing 1 is a front view of the present utility model, and accompanying drawing 2 is left views.

Embodiment of the present utility model is: hang the suspender in groups that 5 tons of fixing rotary hoisting cranes in lotus and forward position, jetty pier are complementary, upper and

lower load grillage

6,7, positioning plate 4 and locating piece 10 are all made with channel-section steel and steel plate, load push rod 5, make with steel pipe, universal fixed pulley 3, steel rope 2 and suspension hook 8,9, carrying rope band 14 equal selection standard spare and approved products, the overall long 2500MM of overall dimensions, wide 1250MM, high 600MM, about 400kg that conducts oneself with dignity, 3 tons of safety jaw lotuses.

Claims

1, a kind of mechanical device that is used for unitized cargo handling and pile bag, bundled goods, members such as suspension hook and steel rope are arranged, it is characterized in that by last load grillage parts, following load grillage parts, universal fixed pulley and steel rope are formed the tension type pre-tightening mechanism, there are two knock holees [12] four jiaos of centres that universal fixed pulley [3], last load grillage [6] are housed respectively at last load grillage [6], also have a plurality of hook on hole [16], be installed with ordinary lifting hook [8] and the convertible suspension hook of weight [9] in the hook on hole [16], each suspension hook upper end all is inserted with suspension hook lateral pin [17]; Be fixed with locating piece [10] respectively at following load grillage [7] two ends, center fixed has load push rod [5], after load push rod [5] passes knock hole [12], and upper end fixed limit piece [4]; After steel rope [2] passed universal fixed pulley [3] and suspension ring [1], the middle part that head [11] is fixed on positioning plate [4] was pricked with steel wire in its two ends.
