Detailed Description

As shown in fig. 1-2, the fifth spreader assembly dedicated lifting appliance includes a frame body 1, the frame body 1 is composed of a lifting ring component 2, a cross bar 3, a suspension arm 4, a lifting hook 5 and a connecting rod 6, the lifting ring component 2 is formed by connecting a plurality of iron rings in series, and the lifting ring component 2 is in an inverted Y-shaped structure and is used as a main body component for bearing, and is formed by bending and processing round steel with a diameter of 5 into the iron rings in series. The lifting ring component 2 is arranged in a three-section separated mode, the upper portion of the lifting ring component 2 is connected with lifting equipment, two ends of the lower portion of the lifting ring component 2 are hung at two ends of the cross rod 3 respectively and are in central symmetry, and the upper portion and the lower portion of the lifting ring component 2 are connected through a central ring. The chain type structure is high in strength, convenient to produce, stable in connection and cost-saving.

3 both ends of horizontal pole have connecting portion 7, connecting portion 7 be L shape structure, davit 4 and lifting hook 5 respectively be equipped with four, davit 4 have annular portion 8 that cup joints, connecting portion 7 and the cooperation of cup jointing between the portion 8, and every connecting portion 7 connects two davits 4, davit 4 and lifting hook 5 between movable assembly, lifting hook 5 be the U-shaped structure, davit 4 between be equipped with taut spring 9, lifting hook 5 between be connected through connecting rod 6. The cross rod 3 is formed by bending round steel with the diameter of 15-25 mm. The shape of the connecting part 7 should be turned inwards to prevent the suspension arm 4 from being separated due to excessive stress. The sleeve-joint part 8 is an annular structure, and the connecting part 7 is formed by extending a circle along an L-shaped path. Two suspension arms 4 and lifting hooks 5 are arranged on each side of the cross rod 3, and the cross rod 3, the suspension arms 4 and the lifting hooks 5 are connected in sequence.

The cross rod 3 is provided with a first stop block 10 for limiting the sliding of the lifting ring component 2, and the first stop block 10 is positioned on the inner side of the lifting ring component 2. First dog 10 central symmetry welded fastening is on horizontal pole 3 for carry out limiting displacement to rings subassembly 2, prevent to lift by crane the in-process, rings subassembly 2 receives the influence of gravity and is straightened, causes to hang a piece in-process work piece atress inhomogeneous, causes potential safety hazard etc..

The elastic contraction or expansion direction of the tension spring 9 is vertical to the axial direction of the cross rod 3. The stress direction of the lifting hook 5 during lifting is consistent with the elastic deformation direction of the tension spring 9, and the tension spring 9 prevents the lifting hook 5 from being separated from the fifth cross beam.

The connecting part 7 is provided with a second block 11 for limiting the separation of the suspension arm 4. The effect is mainly to fix davit 4 on horizontal pole 3, makes it firm not displacement, can fix at the both ends of davit 4, and second dog 11 central symmetry sets up on horizontal pole 3, and every second dog 11 all will laminate at the both ends of davit 4, and welded fastening is on horizontal pole 3.

The suspension arm 4 is provided with a buckle 12, the buckle 12 is provided with a clamping hole, and the tension spring 9 and the clamping hole are fixedly assembled. The tension spring 9 is used for mounting and is used for enabling the suspension arm 4 on one side to be always in a tightened state, and the potential safety hazard caused by the fact that the lifting hook 5 is suddenly loosened when a workpiece is lifted is avoided.

The suspension arm 4 is connected with the lifting hook 5 through a ring buckle 13, the ring buckle 13 is of an annular structure, and the ring buckle 13 penetrates through the suspension arm 4 and the lifting hook 5 respectively. The latch closure 13 is used for connecting for connect more flexible, be difficult for causing the damage of hoist or fifth crossbeam when using through flexonics, improve life.

The lifting hook 5 is provided with a mounting seat 14 connected with the buckle 13, the mounting seat 14 is provided with a first mounting hole, and the suspension arm 4 is provided with a second mounting hole. The mounting 14 facilitates the attachment of the hook 5 without the need for machining on the U-shaped structure, thereby affecting the structural strength.

And an anti-skid piece is arranged on the inner wall of the U-shaped opening of the lifting hook 5. The hook 5 is prevented from disengaging by the anti-slip means, which can be provided on the two opposite walls, depending on the actual production situation, and which are not illustrated or limited herein. The cleats may be made of rubber or polyurethane or other suitable materials. Need closely to laminate on lifting hook 5, adopt soft material effect: the first is to prevent the workpiece from shaking when the workpiece is lifted, so as to play a role of skid resistance; secondly, the surface treatment layer of the workpiece at the contact part of the workpiece and the lifting hook 5 is protected from being damaged in the lifting process.

Fixed through four lifting hook 5's both sides for stable during the work piece transport, difficult emergence is collided with and is damaged, and hoist self is installed easily simultaneously, and structural design is reasonable, and life is high.

The invention has the beneficial effects that: the special lifting appliance for the fifth beam assembly is used for replacing the phenomenon that paint falls off due to collision and scratching in the processes of manual carrying, carrying or assembling and the like, is convenient to operate and use, improves the carrying efficiency, reduces the damage, is convenient to produce, and has practicability and economical efficiency.
