Description
Technical Field
The utility model relates to a lifting device, concretely relates to I-steel lifts by crane anchor clamps.
Background
At present, I-steel is widely used and produced in China, and the I-steel is mainly divided into common I-steel, light I-steel and H-shaped steel.
When the steel plate is manufactured, if the quantity is small, the steel plate can be formed by welding and splicing steel plates with equal specifications, if the quantity is large, HW and HN section steels with equivalent mechanical properties are usually considered for replacing the steel plates, and in the large-specification H steel manufacturing, a common elevator has certain limitation, and the elevator can damage the surface of a base metal, seriously influences the appearance quality of a product, is difficult to repair, and wastes time and labor.
When the I-steel is used in a construction site, the I-steel is generally required to be installed after being hoisted to a certain height. During hoisting, no reliable hoisting tool is provided, the hoisting of the steel wire rope is troublesome, and no safer guarantee measures are provided.
Disclosure of Invention
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a simple structure, lift by crane convenient I-steel and lift by crane anchor clamps.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the I-steel lifting clamp is characterized by comprising two flange clamping plates and a lifting ring, wherein the lifting ring penetrates through the upper ends of the two flange clamping plates through a rotating shaft and then is rotatably arranged on the two flange clamping plates, a gap is formed between the lifting ring and the upper ends of the flange clamping plates, and a lifting hook clamping space is formed; the two flange clamping plates can circumferentially rotate by taking the rotating shaft as a center, the inner side of the lower end of each flange clamping plate is provided with a clamping groove matched with the flange of the I-steel to be hoisted, and the two flange clamping plates are outwards rotated to ensure that the two clamping grooves respectively correspond to the two flanges of the I-steel to be hoisted after the lower end of the two flange clamping plates is opened. Therefore, when the flange clamping plate is used, the two flange clamping plates are rotated outwards, so that the clamping grooves of the flange clamping plates correspond to flanges of the I-shaped steel to be hoisted, then the flange clamping plates are pushed towards the flange direction of the I-shaped steel, and the flanges of the I-shaped steel are clamped in the clamping grooves and fixed. At the moment, the lifting hook of the lifting device is hooked on the lifting ring, and the I-shaped steel can be lifted. Therefore, after the lifting clamp is adopted, the I-shaped steel and the clamp can be quickly fixed together, and then the I-shaped steel is lifted together with the lifting device. Meanwhile, the hoisting clamp is assembled only through the flange clamping plate and the hoisting ring, the number of clamp assembling parts is small, the structure is simple, and the cost is low.
Furthermore, a positioning piece is arranged on the two flange clamping plates and below the rotating ends of the flange clamping plates, and the positioning piece can fix the two flange clamping plates together after the flange clamping plates rotate to a certain angle. Like this, through setting up the setting element, can rotate suitable position back at the edge of a wing cardboard, fix both edges of a wing cardboard with the locating piece together, prevent that the rotation angle between the edge of a wing cardboard from changing, and then can ensure that both edges of a wing cardboard can be fixed together with the I-steel of hoist and mount well to can not drop at the hoist and mount in-process.
Furthermore, the positioning piece comprises a positioning bolt, and one end of the positioning bolt penetrates through the two flange clamping plates and then is in threaded fit with the positioning nut to fix the two flange clamping plates together. Like this, adopt positioning bolt and set nut as the setting element, it is effectual to fasten through the screw fastening back, is difficult for droing, and the cost is low, can also remove the fixed of two flange cardboards after using the completion, makes its hoist and mount that adapt to other I-steel to be convenient for when hoist next time, with wait to hoist the I-steel flange and fix together fast.
Furthermore, the hoisting ring is a U-shaped plate with the left end and the right end bent downwards, and the lower end opening of the hoisting ring is clamped outside the two flange clamping plates. Like this, the bending part of lifting ring can overlap the back with the edge of a wing cardboard outside and be connected to form the card of a lifting hook with edge of a wing cardboard upper end and go into the space.
Furthermore, the rotating shaft is a bolt, and one end of the bolt penetrates through the bending parts of the two flange clamping plates and the U-shaped plate and then is matched with a nut. Like this, replace traditional pivot through the bolt to with the length of nut injecing the pivot, can ensure that the edge of a wing cardboard and play the rings between mutually noninterference, have good turning clearance. Meanwhile, the bolts and the nuts have low manufacturing cost and are convenient to install and disassemble.
Further, the flange clamping plate and the lifting ring are both made of steel plates. Like this, the intensity of edge of a wing cardboard and hoisting ring is all higher, can satisfy the intensity demand of lifting by crane.
Furthermore, the clamping groove of each flange clamping plate is arranged in an upward inclined mode towards the clamping end of the flange clamping plate. Like this, after outwards rotating flange cardboard to certain angle, just can ensure that the draw-in groove is horizontal setting.
Furthermore, the width of the clamping end of the clamping groove is larger than the width of the inner end of the clamping groove. Therefore, the flange clamping plate can be conveniently clamped.
Furthermore, a U-shaped pad is arranged in the clamping groove of each flange clamping plate and is made of elastic materials. Like this, can reduce the wearing and tearing on draw-in groove and edge of a wing when the I-steel edge of a wing blocks in, simultaneously, the U type pad has elasticity to have less deformation, laminate well with the I-steel edge of a wing.
Furthermore, the flange clamping plates are rectangular, and corners of the flange clamping plates are fillets. Thus, the flange clamping plate can be prevented from damaging an operator.
