Description

A clamping sling with adjustable width for hoisting square tubular objects

technical field

The utility model relates to a clamping structure for a square object, in particular to a clamping sling with adjustable width for hoisting a square tubular object, which is used for clamping and hoisting different width of a square tubular object.

Background technique

The prefabricated embryo body of the square tube with low strength is often lifted and transported with cloth slings before being sent into the steam curing room or baking furnace. For factories with large production volumes, the labor intensity of workers wearing and unloading suspenders is relatively large, time-consuming and laborious, and the same is true when loading and unloading finished products. For large batches of tubular objects of different specifications, although there is no need to consider the width of the tubular object too much when using cloth slings, which has certain advantages, the efficiency is still low. For square tubes with rough surfaces, cloth slings have a limited lifespan and consume a lot when the square tubes are hoisted and transported in batches. However, those who use steel wire ropes are easy to damage the outer surface and even the structure of the square pipe due to the line contact.

Contents of the invention

The arm is connected to the pulley block through the connecting shaft between the pulley and the connecting arm, and the L-shaped clamping arm and the connecting arm are provided with triangular reinforcing ribs.

Further, the inner surface of the L-shaped clamping arm is a plane, the outer side has a reinforcing rib with a semicircular cross-section, and the transition angle radius of the L-shaped root is smaller than R2.

Further, the angle between the clamping arm and the connecting arm is 120 degrees.

Further, there are two triangular reinforcing ribs at the welding place between the clamping arm and the connecting arm.

Further, the number of the adjustment mounting holes can be flexibly set according to product specifications.

Further, the upper end of each connecting arm is connected to a set of pulleys, a total of 2 sets, and the pulleys and the connecting arms are connected through connecting shafts.

Further, the cross-arm is made of channel steel, and there are 3 fixing holes in the middle and both ends of the cross-arm.

Further, the suspension ring and the cross arm are clamped and connected to each other by three nuts to prevent loosening.

Further, the above-mentioned sling constitutes the hook assembly, which is connected with the cross-arm hook by the wire rope through the pulley block.

When in use, lower the sling, separate the opposite L-shaped clamping arms in the hook assembly, make the bottom hook hook the bottom of the square pipe, raise the driving hook to lift the sling, drive the connecting arm through the pulley block, and the clamping arm Hold the embryo body and lift it.

The hook assembly has a pair of pulleys. The pulleys are tightened with the wire rope. The clamping arm is in contact with the side surface of the embryo body. When lifting and transporting, the surface of the pipe body with low strength and its structure are avoided from being damaged; the lifting device of the above structure is used as a hook assembly, and a pair of the above assemblies are used to install it on the cross arm, and the driving hook lifts the cross arm. The lifting ring on the shoulder can smoothly hoist and transport square tubular objects.

There are adjustment mounting holes on the connecting arm. The specifications of the square tube are known. When the specifications are different, the adjustment installation shaft is installed on the corresponding adjustment installation hole to ensure fit and clamping.

After the structure of the entire spreader is strengthened, it can also be used for lifting and transporting other types of square objects.

The utility model has the advantages of simple manufacture, convenient adjustment of the lifting width, flexible operation, convenient movement, time saving and labor saving, and high lifting efficiency.
