Abstract

The utility model belongs to the construction machinery, in particular to a mechanical vice at the end part of an excavator, which comprises a cab (1), a big arm (2), a big arm hydraulic cylinder (3), a small arm (4) and a small arm hydraulic cylinder (5), wherein, a small arm cylinder pin shaft (5-1) is arranged on one end head of a piston rod of the small arm hydraulic cylinder (5), a lower vice arm (6) and an upper vice arm (10) are movably arranged on the pin shaft (5-1), a lower vice body (9) and an upper vice body (7) are hinge-jointed at the other end heads of the upper vice arm (6) and the lower vice arm (10) respectively, the upper vice body (7) and the lower vice body (9) are hinge-jointed together by a vice body connecting pin shaft (7-1), triangular vice teeth (8) are disposed on inner surfaces of the upper vice body (7) and the lower vice body (9), the mechanical vice at the end part of the excavator can be refitted from the existing excavator, and can also be refitted to the excavator when not in use, and the mechanical vice can flexibly and rapidly carry bar shape heavy objects, and is particularly applied to the post-quake relief work.

Description

Excavator end machinery pincers

Technical field

The utility model belongs to engineering machinery, particularly a kind of excavator end machinery pincers.

Background technology

At present, existing large-scale handling machinery quantity seldom, and cost is very high, use is also few at ordinary times, existing excavator quantity is very big, be used for ditching and the native stone of carrying, but the carrying of the weight of and bar shaped big for volume is just very difficult more, even does not realize.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of excavator end machinery pincers that can carry large volume and bar shaped weight fast are provided.

The technical scheme that the utility model technical solution problem adopts is: excavator end machinery pincers comprise driver's cabin, big arm, big arm hydraulic cylinder, forearm, little arm hydraulic cylinder, be characterized in being provided with forearm cylinder bearing pin at the piston rod end of little arm hydraulic cylinder, be equipped with versatilely on the bearing pin down the pincers support arm and on clamp support arm, another termination at last pincers support arm and following pincers support arm is hinged lower clamp and upper clamp, upper clamp is connected bearing pin with lower clamp with caliper and is hinged together, establishes triangle clamp tooth on upper and lower caliper inner face.

The beneficial effects of the utility model are: excavator end machinery pincers can be with existing excavator repacking, and the time spent can not reequiped back excavator again, and mechanical pincers can be carried the bar shaped weight flexibly apace, be specially adapted to the work of requiring assistance after the earthquake calamity.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is excavator end machinery wrench structure figure.

Among the figure, the 1-driver's cabin; The big arm of 2-; The big arm of 2-1-connects bearing pin; The big arm hydraulic cylinder of 3-; The 4-forearm; 4-1-forearm, big arm hydraulic cylinder connect bearing pin; The little arm hydraulic cylinder of 5-; 5-1-forearm hydraulic cylinder bearing pin; The last pincers of 6-support arm; The last pincers of 6-1-support arm bearing pin; The 7-upper clamp; The 7-1-caliper connects bearing pin; 8-clamps tooth; The 9-lower clamp; 10-is the pincers support arm down; 10-1-is pincers support arm bearing pin down;

The specific embodiment

Embodiment, with reference to accompanying drawing 1, on driver's cabin 1 one sides of excavator end machinery pincers big arm 2 is housed, above the big arm 2 big arm hydraulic cylinder 3 is housed, the piston rod end of big arm hydraulic cylinder 3 is connected forearm 4 with big arm 2 terminations with bearing pin 2-1 with bearing pin 4-1, on forearm 4, adorn a forearm hydraulic cylinder 5; piston rod end of forearm hydraulic cylinder 5 is gone up pincers support arm 6 and pincers support arm 10 down with forearm hydraulic cylinder bearing pin 5-1 connections; on clamp support arm 6 and use pincers support arm bearing pin 6-1 and connect upper clamp 7; clamp support arm bearing pin 10-1 connection lower clamp 9 down under pincers support arm 10 usefulness, upper clamp 7 and lower clamp 9 usefulness caliper bearing pin 7-1 are hinged together.Be provided with triangle clamp tooth 8 on the inner face of upper and lower caliper 7 and 9, upper and lower caliper 7,9 opening and closing under the drive of forearm hydraulic cylinder 5 promptly can be clamped and are handled upside down thing, carry object apace.
