Abstract

The utility model discloses lifting clamp which is composed of a claw beam, a pin shaft bolt, an articulating shaft, a pressing block and a clamp body, wherein the claw beam is in a V-shaped structure, the bent part of the claw beam is mounted on the clamp body by use of the pin shaft bolt, and one end of the claw beam is articulated with the pressing block by the articulating shaft; the clamp body is in a U-shaped structure; the pressing block is arranged on side inside the clamp body, and rubber block components are respectively fixedly arranged on the other side of the clamp body and the pressing block. The lifting clamp disclosed by the utility model can satisfy the requirements of horizontal lifting, vertical lifting and rollover of most of structural members and H-shaped steel and also causes no scratch or damage to lifted objects.

Description

Tongs

Technical field

The utility model relates to hoisting technology field, especially a kind of tongs.

Background technology

Conventionally in, the welding of large-sized structural parts, processing, and in spraying process, need it repeatedly to overturn to change posture and angle, and lifting that can be repeated.In lifting and switching process, the overturning pliers that adopt are realized more at present, because the pincers tongue material of overturning plier is alloy steel, and pincers tooth is processed into zigzag fashion, so inevitably suspended object surface is produced and is scratched in manufactured product hoisting process, and part-structure part, half-blank, finished product after especially having sprayed do not allow to produce cut especially.

Utility model content

The utility model, for the deficiencies in the prior art, proposes a kind of tongs, and structure is small and exquisite, light, effectively protects suspended object to avoid scratching, and can meet suspended object horizontal hung, perpendicularly hang and overturn.

In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of tongs, formed by claw beam, pin bolt, jointed shaft, briquetting and caliper, and claw beam is V-structure, its kink is arranged on caliper by pin bolt, and one end is hinged by jointed shaft and briquetting; Caliper is U-shaped structure, and briquetting is located at the side in caliper, on opposite side He on briquetting, is all fixed with rubber block assembly.

Further, on this caliper outside, sleeve pipe is installed, sleeve pipe is provided with operating handle.

Further, this rubber block assembly is arranged on briquetting, caliper through tie bolt.

Further, this briquetting is U-shaped structure.

Compared with prior art, the utlity model has following advantage: can meet the horizontal of most of framing members, H shaped steel and hang, erect and hang and overturn, and these suspended objects are not produced to scuffing, infringement.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Wherein: 1. claw beam 2. pin bolt 3. jointed shaft 4.U type briquetting 5. rubber block jaw assembly 6. caliper 7. holding screw 8. operating handle 9. sleeve pipe 10. tie bolts.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

A kind of zero damage tongs as shown in Figure 1, claw beam 1 is V-structure, and its kink is arranged on caliper 6 by pin bolt 2, and one end is hinged with U-shaped briquetting 4 by jointed shaft 3, jointed shaft 3 and U-shaped briquetting 4 are determined 7 fastening by clamp screw, so just formed lever hold-down mechanism.Caliper 6 is U-shaped structure, and U-shaped briquetting 4 is located at the side in caliper, on opposite side He on U-shaped briquetting 4, is all fixed with rubber block assembly 5.Rubber block assembly 5 is installed on U-shaped briquetting 4 and caliper 6 by tie bolt 10, contacts make its surface avoid damage by rubber block assembly 5 with gripped object.On caliper 6, be welded with sleeve pipe 9, operating handle 8 is installed on sleeve pipe 9, operating handle 8 can be done 180 ° relative to caliper 6 and rotate, and facilitates each operating mode operation.

Rubber block assembly 5 is to be combined through special process by rubber and steel plate groove, forms integral module.It is little that this module has prepressing deformation, and compressive strength is high; Area of contact is large, and anti-local deformation ability is strong; The features such as module is independent, and quick change effect is remarkable, can effectively prevent suspended object damage.
