Abstract

The utility model provides a special hanger for loading and unloading a heavy duty steel pipe, which comprises four same groups of connecting shackles and steel rope slings, and the connecting shackles and the steel rope slings are sequentially connected with a clamping head. The clamping head forms a C shape, the inner side of the clamping opening of the clamping head is provided with a guard plate, a rubber pad is embedded in the upper surface of the bottom part of the guard plate, and the end part of each group of the steel rope slings is connected with a balancing beam. The utility model has the advantages of reasonable designed structure, light weight, heavy loading, high intensity, small investment, obvious effect, simple operation and application, stable goods lifting, safety and reliability, and can improve the operation safety and the quality of goods operation, reduce the labor intensity of workers by more than 50 percent, decrease the number of operation workers on line and enhance the operation efficiency by about twice. Meanwhile, the processing fee of the steel ropes and the slings can be greatly saved.

Description

The special hanger of heavy steel pipe loading and unloading

Technical field

The utility model belongs to the harbour handling steel tools, particularly a kind of special hanger of heavy steel pipe loading and unloading.

Background technology

Along with heavy steel pipe, for example single weight 5t is above, the import and export amount of diameter more than 1 meter, the steel pipe of length more than 12 meters increases year by year, single weight 8t particularly, the loading and unloading operation of the natural gas delivery pipe that is used to transfer natural gas from the west to the east, because of cargo interests to the requirements for quality height, the goods substance is big, brings very big difficulty and very easily has an accident to operation.According to operation technique scheme in the past, re-use the mode of operation that steel rope is tied up the hoist cable lifting after in unloading automobile, train, stacking and de-stacking ship-loading operation process, all being to use wire rope sling to hang head earlier.Not only cause a large amount of damages of wire rope sling to scrap, and flow chart is many, efficient is low, the hoisting crane fuel oil consumption is big.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of special hanger of heavy steel pipe loading and unloading is provided, is beneficial to reach the raising handling efficiency, guarantee job safety, guarantee the purpose of loading and unloading quality.

For achieving the above object, the technical scheme that the utility model adopted provides a kind of special hanger of heavy steel pipe loading and unloading, wherein: this special hanger include identical four groups with dop bonded assembly joining shackle, wire rope sling successively, described dop is " C " type, the bayonet socket inboard of dop is provided with backplate, on the bottom of backplate, stud with rubber pad, be connected with equalizing bar in the end of described each group wire rope sling.

Effect of the present utility model be this suspender project organization rationally, from heavy and light, load is big, intensity is high, small investment, instant effect.Use simple to operately, goods lifting steadily, and is safe and reliable.Put into operation in 3 years so far, any job safety and quality accident do not take place, compare former loading and unloading process program, have following characteristics:

1. the design of this special hanger, actual from producing, guaranteed the cargo operation quality, obtained the favorable comment of owner of cargo unit.

2. guaranteeing to have reduced labor strength more than 50% under the job safety prerequisite, reduced by 2 operation informant persons, improved nearly 2 times of operating efficiency.

3. steel rope and hoist cable processing charges have been saved in a large number.

4. after using from going into operation, it is about more than 300,000 yuan to can be company's innovation economic benefit year.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings is illustrated the special hanger structure that heavy steel pipe of the present utility model loads and unloads.

The special hanger structure of heavy steel pipe loading and unloading of the present utility model is: this special hanger include identical four groups with dop 2 bonded assembly joining shackle 1, wire rope sling 6 successively, described dop 2 is " C " type, the bayonet socket inboard of dop 2 is provided with backplate 3, on the bottom of backplate 3, stud with rubber pad 4, end at described each group wire rope sling 6 is connected with equalizing bar 5, and described equalizing bar 5 is the rectangle equalizing bar.

The special hanger of heavy steel pipe loading and unloading of the present utility model mainly contains dop 2, joining shackle 1, wire rope sling 6 and equalizing bar 5 four parts and combines.Wherein dop 2 mainly is " C " type shape, and the bayonet socket inboard is welded with backplate 3, and studs with rubber pad 4 on backplate 3 bottoms, and is not frayed with protection steel pipe end face.The top of dop 2 be provided with circular hole and successively joining shackle 1 and wire rope sling 6 form one group, be equipped with the equalizing bar 5 that is connected with rectangle with four groups wire rope sling 6 upper ends of spline structure.Dop 2 uses 16Mn high tensile steel plate Combination Welding to form, every safety load 4t, and per two is one group, and two groups is a cover, and safety load is the 16t/ cover, can lift 2 steel pipes simultaneously.

During use,, utilize the centripetal force of steel rope lifting angle, dop 2 is firmly blocked steel pipe, can lift by crane two steel pipes simultaneously, finish the one-stop operation process corresponding respectively being stuck in the two ends pipe of two steel pipes of 4 dops 2 of every cover special hanger.

This suspender is applicable to loading and unloading vehicle, the heap de-stacking operation process of steel pipe goods class.

This suspender is when operation, should earlier special hanger be hung on the crane hook by shackle 1 and wire rope sling 6 bonded assembly equalizing bars 5, after commander's crane driver rises to suitable height, this suspender correspondence successively is stuck in two steel pipe two ends pipes again, can commands lifting.When plucking suspender, only need suspender is extracted out, removed, promptly finish handling process one time.
