Abstract
The utility model belongs to the field of matched manufacturing of mechanical parts, and particularly relates to a safety lifting appliance. The safety lifting appliance comprises an L-shape left lifting plate and an L-shaped right lifting plate, wherein the middles of the left lifting plate and the right lifting plate are articulated with each other through a pin roll, clamping plates are respectively welded at the bottoms of the left lifting plate and the right lifting plate, connecting holes are respectively formed in the tops of the left lifting plate and the right lifting plate, lifting ropes are connected inside the connecting holes, and lifting rings are connected in the middles of the lifting ropes. The safety lifting appliance is simple and practical in structure; the two clamping plates can be tightly clamped inside a box in the lifting process so as to prevent the box from falling off in a halfway.
Description
Technical field
The utility model belongs to the supporting manufacturing of component of machine field, relates in particular to a kind of safe suspender.
Background technology
In the supporting manufacturing of component of machine field, the equipment that lifts at present square box is mainly overhead traveling crane or weight-lifting equipment, by the bending suspension hook, it is transported.Adopt this mode, because suspension hook and square box do not have suitable point of connection to cause friction force very little, connect insecurely, casing very easily drops in moving process and stabs the workman.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of safe suspender is provided, and is convenient to lift square box, prevents that casing from dropping in moving process.
The utility model for achieving the above object, by the following technical solutions: a kind of safe suspender, it is characterized in that: the left and right boatswain chair that comprises " L " shape, described left and right boatswain chair middle part is hinged by bearing pin, the bottom of described left and right boatswain chair is welded with respectively head clamp, the top of described left and right boatswain chair is respectively equipped with connecting bore, is connected with lifting rope in described connecting bore, is connected with in the middle part of lifting rope and hangs circle.
The middle part of described right boatswain chair is provided with strip shape gob, and described left boatswain chair coordinates with this strip shape gob.
Be provided with reinforced rib between described head clamp and described left and right boatswain chair.
Beneficial effect: the utility model is simple in structure, practical, and two head clamps can be stuck in the inside of casing closely in the process of lifting, prevent from falling midway.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of square box in the utility model;
In figure: 1, left boatswain chair; 2, right boatswain chair; 3, bearing pin; 4, head clamp; 5, connecting bore; 6, lifting rope; 7, hang circle; 8, strip shape gob; 9, reinforced rib.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of safe suspender, the left and right boatswain chair 1,2 that comprises " L " shape, described left and right boatswain chair middle part is hinged by bearing pin 3, specifically, and the bending part at the middle part of left and right boatswain chair, in the stressed situation in the long limit of left and right boatswain chair, minor face is unfolded, the inside of chucking square box, thus realize safty hoisting.In the utility model, in order to increase the area of thrust surface of left and right boatswain chair minor face, increase the safety of suspender, the bottom of described left and right boatswain chair is welded with respectively head clamp 4, the bottom vertical weld together of head clamp and left and right boatswain chair, semicircular in shape, the inside area of contact of such two head clamps and square box increases, and has improved the stability of suspender.Be respectively equipped with connecting bore 5 on the top of left and right boatswain chair, be connected with lifting rope 6 in described connecting bore, lifting rope can be iron chains, and lifting rope middle part is connected with hangs circle 7, hangs circle and directly is connected with the suspension hook of the suspension hook of overhead traveling crane or the crane that can move, when hanging circle when stressed, the top, long limit of left and right boatswain chair is inwardly closed, left boatswain chair can be along with the increase of strength upwards slowly the direction of boatswain chair to the right move, simultaneously, the minor face of left and right boatswain chair can outwards open, and lifting is realized in the inside of card machine square box.
In the utility model, for the ease of attractive in appearance, the middle part of described right boatswain chair is provided with strip shape gob 8, and described left boatswain chair coordinates with this strip shape gob, and namely this left boatswain chair can rotate in the strip shape gob that is inserted into right boatswain chair centered by bearing pin.In order to guarantee the fastness between head clamp and left and right boatswain chair, be provided with reinforced rib 9 between described head clamp and described left and right boatswain chair, reinforced rib is welded on the side of left and right boatswain chair.
The utility model is simple in structure, practical, and two head clamps can be stuck in the inside of casing closely in the process of lifting, prevent from falling midway.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
