Description

Graphite rod stone tongs

Technical Field

The utility model relates to a lifting device, especially a graphite rod stone tongs.

Background

With the development of industrial economy, graphite shock rod materials are more and more widely applied, such as graphite crucibles made of graphite in the metallurgical industry, piston cups, seal rings and bearings supported by graphite in equipment for conveying corrosive media, and neutron reducers in atomic reactors by using graphite in the atomic energy industry and the national defense industry.

The existing graphite rod clamp is generally a single-piece clamp, the single-piece clamp is formed by hinging two clamping plates with radians, in the clamping process, the graphite rod is not uniform in hand and is easy to incline, the range of the adjusting angle between the two clamping plates is small, the phenomenon that the graphite rod falls off in the hoisting process is easy to occur, and potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a graphite rod stone tongs, it aims at solving the problem that hoist and mount in-process graphite rod drops easily, and the security is high.

The utility model adopts the following technical scheme:

the utility model provides a graphite rod stone tongs, includes centre gripping unit and rings, and the top of centre gripping unit is arranged in to rings, and the centre gripping unit includes crotch one, crotch two, the bracing piece, and connecting rod one and connecting rod two, the bracing piece is articulated with connecting rod one and connecting rod two through round pin axle one, and connecting rod one is articulated with crotch one through round pin axle two, and connecting rod two is articulated with crotch two through round pin axle three, and crotch one is articulated with the middle part cross arrangement of crotch two.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an increase connecting rod one and connecting rod two for this device is at hoist and mount in-process, and the angle that makes crotch one and crotch two diminishes through carrying to draw, improves the clamp force between crotch one, crotch two and the graphite rod, improves the stability of hoist and mount, prevents that the graphite rod from droing from the crotch, improves the security of hoist and mount.

Further, the utility model discloses a preferred scheme is:

the clamping units comprise two groups which are bilaterally symmetrical, the tops of the two supporting rods are connected through a fixed shaft, and the hanging ring is arranged on the fixed shaft; the lower ends of the two support rods are coaxially hinged with the upper end of the first connecting rod and the upper end of the second connecting rod of each group through a first pin shaft; the lower ends of the first two groups of connecting rods and the first hooks are coaxially hinged through a second pin shaft, and the lower ends of the second two groups of connecting rods and the hooks are coaxially hinged through a third pin shaft.

FIG. 1 is a schematic view of the present invention;

FIG. 2 is a side view of FIG. 1;

in the figure: a hoisting ring 1; a support rod 2; a first connecting rod 3; a second connecting rod 4; a first hook 5; a second hook 6; a first pin shaft 7; a second pin shaft 8; a third pin shaft 9; a pin shaft four 10; a graphite rod 11; a stationary shaft 12.

Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

Referring to the attached drawing 1, the graphite rod hoisting clamp mainly comprises two groups of symmetrical clamping units and a hanging ring 1 and the like, wherein each group of clamping units respectively comprises a first hook 5, a second hook 6, a supporting rod 2, a first connecting rod 3, a second connecting rod 4 and the like.

The lower end of the supporting rod 2 of each group of clamping units is provided with a round hole, the upper ends of the first connecting rod 3 and the second connecting rod 4 are also respectively provided with a round hole correspondingly, and the upper ends of the first connecting rod 3 and the second connecting rod 4 are respectively hinged with the supporting rod 2 through a first pin shaft 7 arranged in the round holes; round holes are also formed in the lower end of the connecting rod I4 and the upper end of the hook I5 respectively, and the connecting rod I3 is hinged with the hook I5 through a pin shaft II 8 arranged in the round holes; round holes are respectively formed in the lower end of the connecting rod II 4 and the upper end of the hook II 6, and the connecting rod II 4 is hinged with the hook II 6 through a pin shaft III 9 arranged in the round holes; the first hook 5 and the second hook 6 are arranged in a crossed mode, and the middle of the first hook 5 is hinged to the middle of the second hook 6 through a pin shaft four 10.

In this embodiment, because two sets of symmetrical clamping units are provided, when the two clamping units are connected, the upper ends of the two support rods 2 are welded and fixed by the fixing shaft 12, and the lifting lug 1 is welded on the fixing shaft 12. The lower ends of the two supporting rods 2 are connected with the two clamping units in series through a first pin shaft 7, so that the upper ends of a first connecting rod 3 and a second connecting rod 4 in the two clamping units are coaxially hinged with the supporting rods 2 respectively; the lower ends of the first connecting rods 3 and the first hooks 5 in the two clamping units are connected in series through second hinge pins 8, and the first connecting rods 3 and the first hooks 5 are coaxially hinged; the lower ends of the connecting rods II 4 and the hooks II 6 in the two clamping units are connected in series through the pin shaft III 9, and the two groups of connecting rods II 4 and the hooks II 6 are coaxially hinged; the first hook and the second hook 6 of the two groups of clamping units are coaxially hinged through a pin shaft four 10.

This embodiment is when using, utilize one 5 of crotch and two 6 centre grippings of crotch of two sets of centre gripping units on graphite rod 11, hoist device utilizes the lifting rope that sets up in rings 1 to lift by crane, the hoist and mount in-process, because the centre gripping unit receives ascending pulling force and the gravity of graphite rod 11, contained angle between connecting rod one 3 and the connecting rod two 4 diminishes and stimulates one 5 of crotch and two 6 of crotch respectively and rotates around four 10 of round pin axle, make the contained angle of one 5 of crotch and two 6 diminish, and then increase one 5 of crotch and two 6 clamping-force to graphite rod 11.

This device simple structure makes easily, through increasing connecting rod one 3 and connecting rod two 4, make at the hoist and mount in-process, reduce the contained angle of crotch one 5 and crotch two 6, and then improve crotch one 5, the clamp force between crotch two 6 and the graphite rod 11, guarantee the stability of hoist and mount, bilayer structure is set to this device moreover, through the effect point that increases the hoist and mount of clamping unit increase graphite rod, can prevent effectively that the graphite rod from taking place to incline at hoist and mount in-process, prevent that the graphite rod from droing.

The above is only the concrete implementation of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are included in the protection scope of the present invention.
