CN201284183Y - Sling for loading and unloading section steel - Google Patents

Abstract

The utility model discloses a shaped steel loading sling, which overcomes the defects in the prior art that when the steel rope buckle net is used for lifting loading and unloading vehicles at the two ends of the shaped steel, the steel rope buckle can be damaged, thereby increasing the loading and unloading cost. In the technical proposal, the two ends of a lifting cross bar are respectively tied with two vertical frameworks for bridging the shaped steel through lifting ropes; the lower ends of the two lifting ropes are tied at two ear holes at the top of the two ends of the frameworks; and the central lines of the ear holes and the vertical surface for bridging the shaped steel on the frameworks are not arranged on the identical plane. Because the shaped steel is loaded and unloaded by tying the lifting ropes which are connected with the two ends of the lifting cross bar to the shaped steel which is fixedly arranged in the frameworks capable of tilting back, and the safety performance is good. Simultaneously, the shaped steel is neatly bridged in the framework without damage to the sling, so the operation is simple. Therefore, the utility model completely solves the problem of the cost used for loading and unloading the steel rope buckle. Based on the capacity of loading and unloading 500,000 tons of shaped steel annually, the loading and unloading cost which can be annually saved is more than 500,000 Yuan, thereby improving the economic benefits of the enterprises.

Description

Shaped steel loading and unloading suspender

Technical field

The utility model belongs to handling tool.

Background technology

Along with rapid growth of economy, the use amount of shaped steel is also increasing greatly, and the shaped steel loading and unloading transportation volume on the port and pier all is significantly increased every year.Existing mode of operation to the shaped steel loading and unloading is to use wire line hitch to unload in the lifting of shaped steel two ends pocket.Owing to hang in the process at pocket, between wire line hitch and the shaped steel, particularly produce violent friction between the shaped steel of band such as square steel, I-beam section corner angle, cause the wire line hitch well damage.In order to guarantee the safety of the work of lifting, strict regulations have been done to the standard of scrapping of wire line hitch by country: fracture of wire surpasses 28, eye position and surpasses 11 and can scrap in lay pitch of general place.According to the above-mentioned standard measuring and calculating of using wire line hitch, statistics in the loading and unloading practice, every loading and unloading one kiloton shaped steel will be scrapped about 12-16 of wire line hitchs, cause the shipping and delivery cost of enterprise to improve, and economic benefit is affected.

The utility model content

Technical problem to be solved in the utility model is, overcomes prior art and uses the wire line hitch pocket to hang shaped steel two ends loading-unloading vehicle, damages the shortcoming that wire line hitch improves shipping and delivery cost, and a kind of shaped steel loading and unloading suspender is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: at the two ends of lifting cross bar, respectively with lifting rope system have two settings, between can take the framework of putting shaped steel, the lower end bolt of two lifting ropes on two earholes at top, framework two ends, take on the line of centers of earhole and the framework put shaped steel risers not at grade.

The utility model also has following technical characterictic:

Take on the line of centers of described earhole and the framework put shaped steel risers not at grade, be below the two sheet bendings of relatively erectting hang the earhole of arm-tie, be horizontally installed with depression bar in its salient point position of turning round, hang the parallel bearing bar that is equipped with in arm-tie bottom with depression bar, the risers that forms between depression bar and the bearing bar can be taken and be put shaped steel, the line of centers of depression bar and bearing bar, with about two lines of centres that hang earhole on the arm-tie not at grade;

On the described bearing bar, with the contact surface of shaped steel on be provided with the friction teeth of a plurality of anti-skidding usefulness.

During operation, with two ends is respectively to have the lifting cross bar of described framework to hang on the suspension hook of crane, shaped steel is put well from passing to take between the depression bar of lifting cross bar two ends direct bearing framework and the bearing bar, the operation crane rises arm, clamp and sling together by tying up to lifting of lifting rope on the framework earhole, can will take many shaped steel that are placed on two frameworks.

Advantage of the present utility model and good effect are, because loading and unloading lifting to shaped steel, be by with lifting cross bar two ends bonded assembly lifting rope, tie up to and mention on the earhole of two framework uppers, shaped steel is taken and is put facade not at grade on the line of centers of earhole and the framework, utilizes the leverage extruding shaped steel of framework earhole layback during lifting, and secure placement is in framework, therefore when lifting by crane shaped steel can be in framework play back and forth, safety performance is good; Shaped steel is fitly taken and is placed in the framework simultaneously, and suspender is not damaged, and is easy to use, can substitute the mode of present steel wire buckle loading and unloading shaped steel, thoroughly solved use steel wire buckle loading and unloading shaped steel, and the invar screw thread damages fast and the problem increase shipping and delivery cost.Calculate according to loading and unloading 500,000 tons of shaped steel every year, year save a loading and unloading charge be about 80 surplus ten thousand yuan, improved economic benefit of enterprises.

Description of drawings

Fig. 1 is a schematic perspective view of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, lifting cross bar 4 is used on the suspension hook 6 that lifting rope 5 hangs over crane.Two ends, the left and right sides at lifting cross bar 4, tie up on the earhole 2.2 at two setting tops, framework 1 both sides with lifting rope 3 respectively, can take between two frameworks 1 and put shaped steel, the line of centres of both sides earhole 2.2 is put the shaped steel risers not at grade with framework 1 formed taking.

What the line of centers of described earhole 2.2 and framework 1 formed takes the face of setting level not at grade, is the top of hanging arm-tie 2 at the two sheet bendings of erectting relatively, is respectively equipped with the fixedly earhole 2.2 of lifting rope 3 usefulness; Hang at two bendings and to be positioned between the arm-tie 2 below the earhole 2.2, position at its salient point that turns round 2.1, be horizontally installed with depression bar 1.2, in two bottoms and the depression bar 1.2 parallel bearing bars 1.1 that are equipped with of hanging arm-tie 2, depression bar 1.2 and bearing bar 1.1 hang arm-tie 3 with the setting at two ends, mutual group becomes to settle the setting framework 1 of shaped steel, what form between depression bar 1.2 and the bearing bar 1.1 takes the risers of putting shaped steel, with the line of centres of two earholes 2.2 not in one plane, on carry the lifting rope 3 that ties up on the earhole 2.2, whole framework 1 can produce the layback phenomenon, thereby making shaped steel be subjected to depression bar 1.2 and bearing bar 1.1 scissors clamps and fixes, the weight of shaped steel is big more, and is strong more to the gripping power of shaped steel.

In order further to prevent shaped steel in the slippage of taking after putting into framework 1, on described bearing bar 1.1, be positioned at above the contact surface with shaped steel, be provided with the friction teeth 1.11 of a plurality of anti-skidding usefulness.

Above-mentioned suspender is applicable to all microscler section bar loading and unloading, is particularly useful for the loading and unloading with the long strip of corner angle.
