Description

Stone tongs

Technical field

The utility model relates to a kind of stone tongs, the stone tongs that cooperates wallboard and T row to use in particularly a kind of shipping work.

Background technology

In the ship building process, the installation of fittings needs to use chain block to lift the carry operation in a large number.And the use chain block, maximum problem is: the suspension that at first will solve cucurbit itself.Normally on the position that hangs, be welded and hang sign indicating number, some is nonstandard just directly to be hooked in cucurbit on T row and the wallboard.Be that dangerous also ten minutes is wasted man-hour like this.

The utility model content

The technical problems to be solved in the utility model is that the lifting fittings is time-consuming very unsafe again defective in the existing ship manufacture process in order to overcome, and provides a kind of esy to use, safe and reliable, and improves the stone tongs of lifting efficient greatly.

The utility model solves above-mentioned technical matters by following technical proposals: a kind of stone tongs, and its characteristics are that it comprises: a boatswain chair, it comprises suspension ring that are positioned at its underpart, and one is positioned at the clamp on its top, the horizontal U type bayonet socket of opening of a side of this clamp; One cross-sectional plane be the U type and with this bayonet socket cutting ferrule of scarf mutually, these outside face both sides, cutting ferrule lower end are welded with clamp nut, the corresponding position has bolt hole; The following press strip that the lower end surface of one end and this cutting ferrule flexibly connects; One other end by bolt and this time press strip is movably connected and places the ceiling molding of this time press strip top.

Wherein, this boatswain chair can be integral structure, and this clamp and suspension ring are in same plane.

Wherein, the top clamp of this boatswain chair and bottom suspension ring are for dividing a body structure, and these suspension ring and clamp are that crosswise is welded.

In the above-mentioned split type boatswain chair, the upper end of these suspension ring has a recess, and this notch width and clamp thickness match.

Above-mentioned stone tongs, the flexible connection of this time press strip and cutting ferrule is for articulating, and this hinge device comprises: a sleeve pipe, one places in this sleeve pipe and the nutted screw rod of afterbody, and this Socket welding is connected between the lower surface of an end of this time press strip and this cutting ferrule.

Wherein, this time press strip and ceiling molding junction have bolt hole.

Wherein, this bayonet socket is positioned at the middle part of this clamp.

Wherein, this bayonet socket is an opening horizontal U type mouth left.

Wherein, these suspension ring are semicircle or hook-shaped.

Positive progressive effect of the present utility model is: the utility model is simple in structure easily to be made, esy to use, safe and reliable, has improved the efficient of lifting greatly, and has effectively avoided hanging piece to come off and casualty accident.

The specific embodiment

Lift several preferred embodiments below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

Embodiment 1

As shown in Figures 1 to 4, Fig. 1 is the constructional drawing of the utility model first embodiment.Wherein long and short dash line partly is T row 7.

As shown in Figure 1 to Figure 3, a kind of stone tongs, it comprises: be integrally-built boatswain chair 1, as shown in Figure 3, semicircle suspension ring 11 are processed in its underpart, and top is clamp 12.Clamp 12 1 middle side parts are opened a horizontal U type bayonet socket; One prolate shape cutting ferrule 2, the cross-sectional plane of this cutting ferrule 2 also are horizontal U type, and the U type bayonet socket of this U type openings of sizes and clamp 12 is scarf mutually.As shown in Figure 2, cutting ferrule 2 openings are welded in the U type bayonet socket of boatswain chair 1 towards a left side.Cutting ferrule 2 lower end outside face bilateral symmetry are welded with clamp nut 21, have bolt hole in the corresponding position of cutting ferrule 2 and clamp nut 21.During lifting,, stone tongs can be vertically fixed on the T row 7 by bolts and nuts 21.

As shown in Figure 1, this stone tongs also comprises press strip 3, and the lower end of one end and cutting ferrule 2 articulates, and as shown in Figure 4, this hinge device 5 is by sleeve pipe 51 and place in the sleeve pipe 51 and screw rod 52 that afterbody is with nut 53 is formed.Hinge device 5 is welded on down between the lower end of press strip 3 and cutting ferrule 2.As shown in Figure 1, have bolt hole at the other end that plays press strip 3, flexibly connect a ceiling molding 4 by bolt 6, ceiling molding 4 places down the top of press strip 3, and can be relative to following press strip 3 bolt 6 upper and lower moving.When the stone tongs crosswise fixed after T arranges 7 right sides, will be across that T arranges 7 left sides upper and lower two lip-deep ceiling moldings 4, down press strip 3 is fastening by bolt 6, so with the stone tongs crosswise fixed T row 7, prevent that anchor clamps from coming off from T row 7 right side when lifting.

Embodiment 2

To shown in Figure 6, as second kind of embodiment of the present utility model, it is that with the different of first kind of embodiment the boatswain chair 1 of this stone tongs is a split-type structural as Fig. 5, and the semicircle suspension ring 11 of its underpart are independently upper and lower two parts with the clamp 12 on top.The clamp 12 on its top is identical with the structure of the clamp 12 of all-in-one-piece boatswain chair 1 among first embodiment.Suspension ring 11 structures of its underpart then as shown in Figure 6, the upper end of suspension ring 11 has a recess, the thickness of slab of the width of this recess and clamp 12 is complementary, and is installed on the clamp 12 and welding by this recess with suspension ring 11 are crosswise.
