Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1 to 5, the present invention provides a preferable structure of a novel hanger.

As shown in fig. 1 and 2, the novel spreader includes a lifting ring assembly, a pair of clamping arms 20, a pair of clamps 30, and 3 hinge assemblies. Wherein, the top ends of the two clamping arms 20 are hinged to each other by the hoisting ring assembly, and a pair of clamping arms are correspondingly hinged to the bottoms of the two clamping arms to form the clamp sling.

As shown in fig. 2, the clamping arm is a metal long arm, the outer diameter of the clamping arm is gradually reduced from the top end to the bottom end, and through holes for hinging are respectively arranged at the top end and the bottom end of the clamping arm.

As shown in fig. 2, the lifting ring assembly includes a U-shaped lifting ring 10, a pin, and two spacers 12.

U type rings 10 include U type ring and two engaging lugs 11 of being connected with U type ring, U type ring and engaging lug are a body structure setting, are provided with on the engaging lug to be used for articulated through-hole.

The one end of round pin post is provided with and keeps off the ring, the lug of U type rings and the top through-hole of two arm lock are worn to establish by the round pin post, when compressing tightly the end of round pin post and warping, with U type rings and two arm lock reciprocal anchorages to this articulated of realizing U type rings and two arm lock, U type rings and two arm lock can rotate at will around the round pin post.

The two cushion blocks are respectively sleeved on the pin columns and are respectively positioned between the connecting lug and the clamping arm. The setting of cushion is the specification of increase U type rings, and what the displacement of arm lock on the round pin post led to when reducing simultaneously to lift by crane rocks. Because the thickness of arm lock is thinner, two arm lock superimposed thickness still are less, and in order not to let the arm lock displacement, can adopt the rings of two arm lock thicknesses of adaptation, nevertheless this rings can be very little, and this is unfavorable for the lifting hook to hook rings. And improve thickness through the cushion, then can use bigger rings, the lifting eye of rings is bigger, and each type of lifting hook of being convenient for colludes in the rings, and structural strength is better.

As shown in fig. 5, each of the clamps 30 includes a straight rod portion 31 and a clamp portion 32 connected to each other, and the clamp portion 32 is located on a bottom end of the straight rod portion. The clamp is a metal workpiece made of iron or iron alloy, and the straight rod part and the clamp part are welded into an integral structure.

Specifically, the top of the straight rod part 31 and the upward rod body in the middle are provided with through holes for hinging. Wherein, two straight rod portions are articulated each other, make two clamps be the setting of crossing distribution, and the top of two straight rod portions correspond respectively with two the bottom of arm lock is articulated.

As shown in fig. 3, a flat latch 321 extending outward is disposed at the bottom of the pincer portion, so that the pincer portion is in an L-shaped structure; the flat clamping blocks of the two clamps are arranged oppositely.

Specifically, the included angle between the clamp part and the straight rod part is an obtuse angle of 120-140 degrees; the included angle between the flat fixture block and the clamp part is a right angle. Under this design, the open angle of two clamps can be bigger, compares with current clamp hoist, has the interval of bigger adaptation material.

In one embodiment, as shown in fig. 2, the joints between the clamp and the clamp arm and between the two straight rods are connected by a hinge assembly, which includes a pin 40, a spacer 41 and a flexible wire 42.

The pin shaft comprises a cylinder and a cap body, and the outer diameter of the cap body is larger than that of the pin shaft; one end of the column body is connected with the cap body, and the other end of the column body is provided with a through hole; in use, the clamping arms are aligned with the through holes of the clamps or the through holes of the straight rod parts of the two clamps, and the pin shaft is inserted through the clamping arms and the through holes. Then, the adaptive gasket is sleeved on the column body.

The flexible metal wire penetrates through the through hole of the column body, and the gasket is limited by bending the flexible metal wire. The perforation of the outer diameter adaptation cylinder of flexible metal wire penetrates the back and bends wantonly all, can avoid the gasket to break away from the cylinder, through the cap body and the gasket of round pin axle with arm lock and clamp, two clamps and fixed and form hinge structure.

Through the design, the conventional clamp lifting appliance mostly adopts bolts, the assembly and disassembly are troublesome, and the bolts have certain falling risks. And adopt flexible metal wire, can fast loading and unloading, and select for use the flexible metal wire that intensity is good, use more safe and reliable.

In a preferred embodiment, the surfaces of the clamp arms and the clamp are provided with a wear-resistant coating. Because the lifting appliance can be frequently used and can be abraded and damaged by touching materials, the service life can be greatly prolonged by adopting the wear-resistant coating. Can be a nano nickel-based tungsten carbide alloy spray coating.

The clamp of the utility model comprises a lifting ring, a pair of clamping arms and a pair of clamps, wherein, the bottom of the clamp part of the clamp is provided with a flat clamping block extending outwards, so that the clamp part is in an L-shaped structure; the flat clamping blocks of the two clamps are arranged oppositely. The use principle is as follows:

the clamp is made to be adaptive to two side edges of the plate-shaped material by opening the clamp, when the lifting ring of the lifting appliance is pulled up, the two clamps are close to each other under the action of gravity, so that the flat clamping blocks are clamped into the plate-shaped material or the groove of the plate-shaped material. When the plate-shaped material is pulled up, the flat clamping block can block the plate-shaped material from falling, and the plate-shaped material can keep the two clamps in a clamping state under the action force of the flat clamping block, so that the two clamps are difficult to open, the clamping stability is ensured, and the risk of accidents is reduced.

Other structures of the novel sling described in the embodiment are referred to in the prior art.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, so that any modification, equivalent change and modification made by the technical essence of the present invention to the above embodiments do not depart from the technical solution of the present invention, and still fall within the scope of the technical solution of the present invention.
