Detailed Description

As shown in the accompanying drawings, the utility model provides a wire rope hoist for bucket, including fag end rings 5 and around bucket becket bridle 7, fag end rings 5, around bucket bridle 7 be the loop configuration respectively, fag end rings 5 bottom and around between the left end of bucket bridle 7, and fag end rings 5 bottom and around being connected with respectively between the right-hand member of bucket bridle 7 and lifting by crane wire rope 6, fag end rings 5 and lifting by crane are provided with wire rope clamp 3 or metal sleeve between the wire rope 6, around bucket bridle 7 left and right sides department be provided with first becket bridle 2.1 respectively, second becket bridle 2.2, around the clockwise winding of bucket bridle 7 left end to passing second becket bridle 2.2 and being located the right side lift by crane wire rope 6 bottom, anticlockwise winding around bucket bridle 7 right-hand member to passing first becket bridle 2.1 and being located left wire rope and lifting by crane 6 bottom, first becket bridle 2.1, the second becket bridle 2.2 outside is provided with respectively and is used for spacing first wire rope clamp 3.1, second bridle 2.2.

Wherein, the rope lug flying ring 5, the hoisting steel wire rope 6 and the barrel winding rope ring 7 are formed by winding a steel wire rope 4, and the first steel wire rope head 9.1 and the second steel wire rope head 9.2 of the steel wire rope 6 are arranged at the rope lug flying ring 5. At least one first wire rope clamp 3.1 and one second wire rope clamp 3.2 are respectively fixed at symmetrical points on two sides of the middle point of the wire rope 4, and the distance between the two symmetrical points is equal to half of the perimeter under the barrel hoop or under the flange of the lifted article barrel. On the wire rope between two wire rope presss from both sides, the cover has two at least becket, the becket is smooth, the shape of becket is shape such as O type ring, quad ring or 8 word shape ring, specifically, the size of first wire rope clamp 3.1, the narrowest department of second wire rope clamp 3.2 is greater than first becket 2.1, the inside maximum dimension of second becket 2.2 respectively for first becket 2.1, second becket 2.2 can't pass through first wire rope clamp 3.1, second wire rope clamp 3.2 respectively, and then make first wire rope clamp 3.1, second wire rope clamp 3.2 play spacing becket's effect.

The utility model discloses in, first wire rope head 9.1, second wire rope head 9.2 are along clockwise or anticlockwise wound alternately circle separately to continue to pass second becket 2.2, first becket 2.1 in proper order along winding the circle, the simplest of at this moment constitution is around bucket becket 7. At the moment, one part of the steel wire rope wound around the barrel is a single ring of one steel wire rope, and the other part of the steel wire rope is an overlapped circular ring of two steel wire ropes; if both rope ends continue to pass the next metal loop along a winding, the number of overlapping loops increases, preferably only once. A section of steel wire rope is drawn out from the rope ring of the drum winding, the steel wire rope is firstly twisted into an 8-shaped ring, and then the newly twisted ring and the previous rope ring of the drum winding are also sleeved on the hung object, and the operation can be repeated for n times; when n is larger, the friction force between the steel wire ropes and the friction force between the multi-strand steel wire ropes and the barrel body is increased, and the hoisting device can also be suitable for hoisting cylindrical objects without a barrel hoop or a flange.

The rope lug hoisting ring 5 aligns the first steel wire rope head 9.1 and the second steel wire rope head 9.2 and turns back at the same time to form two overlapped rope lug rings, and at least one steel wire rope clamp 3 or a metal sleeve is adopted at the convergence part of the four ropes for clamping, and the rope lug rings are the rope lug hoisting ring 5. The shank rings are preferably arranged on the rope lug hanging rings, and when the pulling force of the steel wire rope is far greater than the weight of the hung object, the shank rings can be not arranged in the rope lug hanging rings. First line nasal part 8.1, second line nasal part 8.2 and fastening are established to the cover respectively on first wire rope head 9.1, the second wire rope head 9.2, avoid the wire rope thorn of fag end to injure the people, form the wire rope head 1.1 of first tape line nasal part, the wire rope head 1.2 of second tape line nasal part. Preferably, the first metal ring 2.1 and the second metal ring 2.2 are fixed to the first wire rope clamp 3.1 and the second wire rope clamp 3.2, respectively. Preferably, because the steel wire rope has the characteristic of rope knotting, the rope lug hanging ring 5, the first metal ring 2.1 and the second metal ring 2.2 are formed by knotting the steel wire rope, or the steel wire rope is formed by fixing the steel wire rope clamp or clamping a sleeve after bending to form a rope lug of the steel wire rope, and the steel wire rope clamp and the metal rings are omitted.

Preferably, 2 metal rings playing a role in limiting, which are called positioning rings for short, 0-X chain rings are linked on the 2 positioning rings and can be used for winding steel wire ropes to pass through; x =0, the aforementioned state is only 2 metal rings. The number of turns k = m + n, n (n =0, 1, 2,. Is a repeated number of turns, which is a natural number), where m is an initial base number of the number of turns around the drum, that is, the first wire rope end 9.1 and the second wire rope end 9.2 are wound into a cross circle clockwise and counterclockwise respectively, and continue to pass through the second metal ring 2.2 and the first metal ring 2.1 in sequence along the cross circle, which constitutes the simplest drum rope winding ring 7. At the moment, one part of the steel wire rope wound around the barrel is a single ring of one steel wire rope, the other part of the steel wire rope is an overlapped circular ring of two steel wire ropes, and the overlapped circular rings of the two steel wire ropes are different due to the fact that the arc distance between the positioning rings is 2.1 and 2.2. The m value intervals m are (1, 1.5) and [1.5, 2), which respectively indicate that the part of the overlapped circular ring is equal to or less than or equal to a semicircle on the basis of a single steel wire rope ring, and the analysis (1, 1.5) and [1.5, 2) is equivalent because whether the circular ring is lifted at two points or is symmetrically lifted is carried out, so that the analysis (1, 1.5) is carried out, when m =1.5, one part of the steel wire rope wound around the barrel is a single ring of 1 steel wire rope, the other part of the steel wire rope is an overlapped circular ring of 2 steel wire ropes, the base number of the wound barrel is 1.5, the total number of the wound barrel k =1.5 n mode, when the steel wire rope is lifted at two points and is symmetrically lifted, the barrel surface in the lifting process is basically horizontal, when m is not equal to 1.5, the m is gradually reduced from 1.5 to be close to and equal to 1, namely when m is approximately equal to 1, two positioning rings are close to together, similar to 1, when m < 1.9, the first steel wire rope is not completely lifted from the first lifting ring and the second steel wire rope, the end is not completely lifted from the second lifting ring, and the end of the steel wire rope is not opened along the incomplete lifting structure.

Preferably, the number of turns of the winding barrel k = m + n mode, when n =0, when two wire rope ends are respectively wound through a metal ring clockwise or counterclockwise, no matter a section of rope is drawn out from a single ring of 1 wire rope or an overlapped ring of 2 wire ropes, an 8-shaped ring is firstly twisted, and then the newly twisted ring is also sleeved on the hung object, so that the number of turns of the winding barrel = m +1; repeating the operation n times constitutes the number of barrel turns = m + n. At this time, the newly twisted rope loop does not pass through the metal loop except the original metal loop. When n is larger, the hoisting tool for the barrel can be suitable for hoisting cylindrical objects without a barrel hoop or a flange due to the increase of the intersection, extrusion and friction among rope rings around the barrel and the friction force between a multi-strand steel wire rope and the barrel body.

After any repetition turns when n ≠ 0, the operation of re-sleeving the barrel by twisting the 8-shaped ring above can also be repeated, also like thunder. After two steel wire rope ends are respectively wound into a cross circle along the clockwise or anticlockwise direction, if the two rope ends continue to wind along the winding circle but do not pass through the metal ring any more, the effect is equivalent to the operation of sleeving the barrel cover again by lifting and twisting 8 words when the two rope ends are repeated for n times. The knotting operation mode can omit a steel wire rope clamp or a metal ring at the knotting position, and has the defects that the friction resistance between the steel wire ropes is far greater than that of a smooth metal ring in the hoisting process, and the tensioning process of the steel wire rope is longer. When the steel wire rope drawn out of the rope ring wound around the bucket of the steel wire rope sling for the bucket is repeatedly twisted into n 8-shaped rings, and then the newly twisted rings are sleeved on the hung object, the method can also be used for hoisting the steel wire rope sling for the bucket by being suitable for cylindrical objects without hoops or flanges.

The utility model discloses when using, will wind bucket becket bridle cover on one's body by the bucket hoop of well-bucket or the bucket under the flange, the fag end rings are hung on the lifting hook and are confirmed, try earlier and hang, and the inspection is by well-bucket, hoist atress condition, then slowly lift by crane after no abnormity, along with draw tight more around bucket becket bridle, the wire rope of pulling out is located to convert at two beckets and is become to lift by crane wire rope, the casket hoop or the flange of bucket play limiting displacement around bucket becket bridle. The lifting appliance is ingenious and simple in design. Two-point hoisting is realized by the two symmetrical metal rings, the stability in the hoisting process is good, the use is safe, and the two-point hoisting device does not loosen and fall off. The method can be suitable for various common industrial metal drums, and can also solve the problem that the necking plastic drum can not be lifted by a common lifting appliance.

The invention will be further described with reference to the following drawings and specific examples:

a maximum circumference of a necking plastic barrel is 1900mm through measurement, the converted maximum diameter is about 605mm, the diameter of a barrel cover is 495mm, and the radius of the maximum diameter is 55mm larger than that of the barrel cover. The outer diameter =495mm +16mm =527mm,16mm of the barrel hoop is the distance between the radial direction of the barrel hoop and the barrel mouth, and the circumference of the barrel neck under the barrel hoop =1580mm. The distance from the edge of the cover surface to the lower edge of the metal barrel hoop is 70mm, and the distance is 50mm larger than the opening size of a conventional sling when the sling is fully opened. Also because of this reason, and the big belly reason of ladle body, cause this kind of throat plastic drum, can't lift by conventional hoist.

Example 1:

the steel wire ropes of 6 × 19 (a) are taken, 6 strands of the steel wire ropes are provided, each strand is synthesized by 19 steel wire strings, the diameter of the cross section of each steel wire rope is measured to be 5.5mm, theoretically, the pulling force of the whole steel wire rope which is broken and broken is not less than 1.37 tons, so that the steel wire ropes of 6 × 19 (a) are completely feasible for hoisting the packaging barrel of about 200Kg, and the steel wire ropes are provided with left and right steel wire ropes during hoisting, and each steel wire rope bears the weight of about 100 Kg.

The calculation method of the approximate data of the length of the steel wire rope is as follows:

taking 1.5 times of the perimeter (1.5 x 1580) of the bucket neck 2370mm, then adding 2 times of the distance from the edge of the bucket cover surface to the lower edge of the metal bucket hoop by 70mm, and then adding the diameter of the bucket cover, wherein the length is the shortest length capable of hoisting. The total is as follows: 2370+2 + 70+495 + 3005mm, and a steel wire rope with the length of more than 3005mm and the length of 3500mm is taken.

Two metal rings are sleeved in the steel wire rope, and the two metal rings are firstly placed at the central point.

At two points of the steel wire rope, the circumference of the barrel neck of which is 790mm and 0.5 x respectively is taken from two sides of the midpoint, a M8U-shaped limiting steel wire rope clamp is respectively fixed, and two metal O-shaped rings are arranged on the steel wire rope between the two steel wire rope clamps. Is defined as: the left side is a first side, the right side is a second side, namely the rope end on the left side is a first steel wire rope end 9.1, a first metal ring 2.1, a first steel wire rope clamp 3.1 and a first wire nose part 8.1; the corresponding right rope end is a second wire rope end 9.2, a second wire rope ring 2.2, a second wire rope clamp 3.2 and a second wire nose part 8.2.

The two ends of the metal O-shaped ring are semicircles, the middle of the metal O-shaped ring is rectangular, the width of the inside of the rectangle is 6.8mm, the inside of the rectangle is larger than the diameter of the steel wire rope by 5.5mm, and the metal O-shaped ring can freely slide on the steel wire rope; the metal O-ring has a diameter of 4.2mm and sufficient tensile strength.

The outer width of the wire rope clamp is 19mm, which is larger than the inner width of the metal ring, so that the metal ring cannot cross the wire rope clamp. In order to ensure the firmness of the clamping of the steel wire rope, the steel wire rope can be wound in the U-shaped groove of the steel wire rope clamp for one or more circles, and then the steel wire rope clamp is screwed, so that the firmness of the steel wire rope in the steel wire rope clamp can be ensured.

Two wire rope heads, the right wire rope detours clockwise, the left wire rope detours anticlockwise or detours in the opposite direction, and then a crossed circular ring can be formed quickly.

The first wire rope head 9.1 will go around clockwise and pass through the second metal ring 2.2 of the wire rope (an O-ring may be used); the second wire rope head 9.2 will go around counter-clockwise and pass through the first metal ring 2.1 (an O-ring may be used) on the wire rope.

Then align two wire rope fag ends to turn back simultaneously, use one to two wire rope clamps of M8 model to fix in four rope departments, form the ear of restricting rings.

At two wire rope heads, each wire nose part is sleeved and fastened, and the increase of the wire nose parts prevents the wire of the wire rope heads from stabbing the skin of the hands or other parts of operators.

To this point, the fabrication is complete.

The thus constructed overlapping circle of the winding drum number =1.5+ n pattern, n =0. Because at least one complete ring is arranged, the structure can prevent the bucket body from being pulled off from the incomplete ring structure of the steel wire rope during the hoisting process of the bucket hoisting tool.

The whole lifting appliance for the steel wire rope barrel is completed by using 3-4M 8 steel wire rope clamps, two metal O-shaped rings, a steel wire rope section and two wire nose parts and then using a wrench.

The two symmetrical metal rings realize two-point hoisting, no inclination exists in the hoisting process, the stability is good, the use is safe, and the looseness and the falling are avoided. Even if the specification or the diameter of the bucket opening of other buckets is too large with the reference bucket opening during the process of manufacturing the lifting appliance for the buckets, two-point lifting is probably changed into approximate one-point lifting, and the lifting function is not influenced at the moment as the conventional one-point lifting appliance.

The hanger is ingenious and simple in design and can be manufactured by one steel wire rope, a plurality of steel wire rope clamps and a metal O-shaped ring. Besides being suitable for common industrial metal barrels, the plastic barrel with the necking function solves the problem that the necking plastic barrel cannot be lifted by a common lifting appliance, and improves the working efficiency.

When a circle of rope is arbitrarily drawn from the rope ring of the winding barrel no matter 1 circle or 2 circles, the 8-shaped ring is firstly twisted, and then the newly twisted ring is also sleeved on the hung object, so that the number of the winding barrel circles = m +1; repeating the operation n times to form the number of barrel turns = m + n. When n is larger, the friction between the steel wire ropes and the friction between the multi-strand steel wire ropes and the barrel body is increased, and the barrel lifting appliance can also be suitable for lifting cylindrical objects without a barrel hoop or a flange.

Example 2:

the two metal rings of embodiment 2 are fixed at two wire rope clamps, which is different from the two metal rings of embodiment 1 that are movable, and the other is the same as embodiment 1.

Example 3:

two wire rope lugs are formed by knotting instead of metal rings, and the rest is the same as that of the embodiment 1.

The present invention is not limited by the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and are all included in the protection scope of the present invention.
