Abstract

The utility model provides a chain pack rigging, the rigging includes a chain, lock hooks running-through the chain, a connection swinging ring is arranged on one end of the chain, the other end of the chain has a shackle, the chain is connected with the wire rope via the shackle, the lock hook consists of a hook ring and a hook body in vertical connection. The utility model is applied by port, railway and cargo yard, which abandons the wire rope pack devices by using the utility model. The utility model has the advantages of high strength, abrasion resistance, less damage for contacting the inclination or edge, which ensures the operation safety. The 90 degrees sliding lock hook adopts the hook body and hook hole vertical connection structure, which is convenient for hooking and increases the lock force of the chain, avoiding the imbalance lifting caused by the friction between the chain and the cargo, or the cargo falling in the air. The service life of the utility model is long; the cost is very low, more than 0.5 million Yuan of wire rope and processing cost can be saved every year.

Description

Chain is tied up rigging

Technical field

The utility model belongs to the special tool of the various five metals section bars of growing up of harbour handling, and particularly a kind of chain is tied up rigging.

Background technology

For many years, the import-export operation of section bars such as the channel-section steel of harbour handling all size, angle steel, screw-thread steel, rail scrap, steel billet is common goods class, this type of section bar is in operation process such as loading and unloading vehicle and loading and unloading boats and ships, traditional power tool is to adopt wire rope sling to hang head always, again the process program of locking and lifting by crane with rope coil.Such operation has not only caused the wearing and tearing of a large amount of wire rope slings to scrap, and the power tool cost increases, and invar silk rope sling very easily takes place rubs the accident that makes goods fall and be caused in the air.

Summary of the invention

For solving the problems of the technologies described above, the purpose of this utility model provides a kind of chain and ties up rigging, is beneficial to improve handling efficiency, guarantees job safety and reduces the power tool cost, guarantees the loading and unloading quality.

For achieving the above object, the technical solution adopted in the utility model provides a kind of chain and ties up rigging, and wherein: this rigging includes chain, on chain, penetrate locking bail, end at chain is connected with the connection suspension ring, and its other end is connected with shackle, and shackle connects wire rope sling.

At described locking bail is to be made of the dog hole circle and the coupler body that are vertical configuration mutually.

The aperture of the dog hole circle of described locking bail is 75mm-110mm.

Effect of the present utility model be this chain tie up rigging at the harbour, units such as railway, goods yard use, and have thoroughly changed the process program that original steel loading and unloading are produced, the steel rope of having eliminated all size hangs, and following characteristics are arranged:

1. this kind rigging in use because of bundle lock goods part all adopts high strength material to make, has intensity height, wear-resistant, contacts non-damageable characteristics with goods angle, angle, has guaranteed the safety of operation.

2. chain is tied up rigging and is taked the vertical 90 ° of structures with dog hole of coupler body, has promptly made things convenient for hook, has increased the coupling mechanism force of chain bundle lock goods again, and the goods of having avoided chain and goods cliding friction to cause lifts by crane the existence of phenomenons such as overbalance, aerial goods extraction.

3. long service life, not fragile in the operation, overhead cost is low.The company that can be every year saves steel rope and processing charges reaches more than 500,000 yuan.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings ties up rigging structure to chain of the present utility model and is illustrated.

Shown in Fig. 1,2,3,4, it is that this rigging includes chain 1 that chain of the present utility model is tied up rigging structure, penetrates locking bail 3 on chain 1, is connected with at an end of chain 1 to connect suspension ring 2, and its other end is connected with shackle 4, and shackle 4 connects wire rope slings 5.

At described locking bail 3 is to be made of dog hole circle 6 that is vertical configuration mutually and coupler body 7.

The top, coupler body 7 bent hook part cross sections of described locking bail 3 is a circular shape.

Chain of the present utility model is tied up 90 ° of slide-and-lock hooks that rigging is achieved in that chain 1 penetrates usefulness and is adopted 25MnV or 20Mn2 high strength bar straight forming after forging, machinework and heat treatment.Its dog hole circle 6 and coupler body 7 be with suspension hook was different in the past, vertical 90 ° mutually of dog hole circle 6 and coupler bodies 7, and the aperture of dog hole circle 6 is 75mm-110mm, can different specification apertures be set according to the difference of lifting payload.Dog hole circle 6 after the increasing can directly penetrate high-test chain, and on chain length, arbitrarily slide freely, be used to tie the section bar of lock and lifting different size and kind, can select the chain of different size and the locking bail 3 of different load for use according to the size of elevator machinery load.(single hook load is divided into 5 tons, 8 tons, 10 tons three kinds of specifications)

This chain is tied up rigging and is connected to form by short wire rope sling 5, high-intensity shackle 4, high-intensity lifting chain 1, the connection suspension ring 2 of locking bail and locking bail 3 five partial devices of 90 ° of slips.Short wire rope sling 5 does not contact goods, mainly plays reduction kit weight and cost and increases goods lifting angle.(the goods horizontal surface after the lifting should be less than 60 ° in the safe angle of tying up rigging)

It is 1 cover that per 2 chains are tied up rigging.During operation, operating worker should be earlier be hung on the nose that hangs of the wire rope sling of rigging on the hoisting crane gib head, when conductor driver places the goods top with a whole set of rigging, the connection suspension ring and the part chain of chain below are passed the goods below, and 90 ° of slide-and-locks are hooked on chain connect on the suspension ring, tighten up chain, promptly finish the process of tying up, and the conductor driver lifting cargo.Use every cover chain to tie up rigging and can lift by crane 10 tons of (or 20 tons) various steel simultaneously, be applicable to the loading, unloading vehicle of section bars such as angle steel, channel-section steel, screw-thread steel, steel billet; Heap, de-stacking and loading, unloading shipping work process.
