1, The overview
Are special tools for large-scale trans-shipment of billets in steel plants, ports, terminals and other units.
2, Billet clamp construction
It is mainly composed of a lifting beam, a connecting rod, an opening and closing mechanism, a synchronizer, a caliper arm, a support plate and a jaw.
The lifting beam is a component connected with the crane hook, and has three structures: a shackle connection, a sling connection and a lifting ear connection. The shackle of the shackle is connected to the hoisting shaft to improve the stress of the sling. At the same time, it avoids the decoupling phenomenon when loading and unloading the slab, reduces the height of the fixture itself, and is beneficial to the use of low places. The slings are connected to the hanging shaft, so that the force of the clamp is good, but the height of the spreader itself is large, and it needs to be used in a large place, and the auxiliary hook is manually used when hanging the hook. The lifting lug of the hanging lug can be directly hooked by the crane driver, but the lifting device should be grounded during the lifting operation, and the hook should be lowered until the force is not applied, which may cause the crane hook to be unhooked.
The connecting rod is the connecting piece of the lifting beam and the caliper arm.
Opening and closing mechanism
The opening and closing mechanism has a manual lift type, (automatic) double hook type, (automatic) single hook type, (automatic) rotary lock type and the like. The automatic opening and closing mechanism is a mechanism for automatically opening and closing the billet fixture. The action does not require any external power source, and the automatic opening and closing of the clamp is realized by the gravity of the clamp itself. Lubrication of the closing mechanism: Lubricate (or oil) must be added regularly (2~3 days), then move up and down several times until the lubrication is complete. Never add excessive grease lubrication!
The synchronizer is a device that ensures the synchronized movement of the clamp arms of the clamp.
The caliper arm is the main force-increasing component of the clamp through which the billet is clamped.
The support plate is a support for the billet holder. The support plate is supported on the upper surface of the steel billet to ensure smooth operation of the opening and closing mechanism of the steel billet clamp.
The jaws have a pinned coupling, a dovetail coupling, and a slotted connector. The jaws are the main part of the direct contact with the billet, which determines the reliability of the billet holder for holding the billet.
3, The features
The principle of leverage is adopted, and the clamping of the billet can be realized without external force assistance, and the clamping is reliable, the movement is flexible, and the lifting is safe and reliable.
The shutter is made of alloy steel with high strength and high wear resistance, which is flexible in operation and long in service life.
The structural are divided into fixed type and adjustable type (height can be steplessly adjustable) to accommodate the lifting of billets of different specifications and different layers.
1. Suspension loading and unloading operations shall be carried out by qualified personnel for hanging and hanging operations.
2. Select the tongs that match the purpose.
3. Use within the allowable load range and must not be overloaded.
4. Use within the allowable thickness range.
5. Do not enter the lifting work area or the flipping area.
6. Do not knock or impact the hanging objects and spreaders.
7. Do not allow the hanging object to move sharply or stop abruptly.
8. Avoid the heavy weight of the hanging objects. For safety, use more than 2 lifting clamps.
9, before use, check, bite, gasket, blockage between teeth, wear and other abnormal phenomena, check and use.
