Abstract

The invention discloses a grabbing machine, and belongs to the field of engineering machines. The grabbing machine solves the problems that an existing grabbing machine is narrow in grabbing range and single in function. According to the grabbing machine, the upper middle of the middle of a base segment (1) is movably connected with one end of a middle segment (2), the upper middle of the middle segment (2) is movably connected with one end of a tail segment (3), and the upper middle of the tail segment (3) is movably connected with one end of a tip segment (4), so that a mechanical finger is formed. The bottom of the base segment (1) of the mechanical finger is fixedly connected with a small arm (10) of a hydraulic machine, the small arm (10) is movably connected to a large arm, the top of a small arm oil cylinder (9) is connected with the small arm (10), and the top of a gripper oil cylinder (8) is connected with the middle segment (2) of the mechanical finger through a pulling wire (5). A plurality of mechanical fingers can be fixedly connected to the small arm (10) so as to form a mechanical arm. The grabbing machine is an engineering facility and is used for road or house construction.

Description

A kind of grapple

Technical field

A kind of grapple, belongs to engineering machinery field.

Background technology

Existing grapple, the narrow range of grasping, and do not there is the function of digging machine.

Summary of the invention

A kind of grapple is provided here, the wide ranges not only grasping, and there is the function of digging machine.But also there is the function of staff of imitation, there is grasping, seize on both sides by the arms, fetch, impact and hold and the function such as pinch.

This invention is such: the place on the upper side, middle part of base pitch (1), and one end of joint (2) in flexible connection, the place on the upper side, middle part of middle joint (2), one end of flexible connection periproct (3), the place on the upper side, middle part of periproct (3), is flexibly connected slightly one end of joint (4).Base pitch (1) top, with the place on the lower side, middle part of periproct (3), be respectively flexibly connected one end of bracing wire (6), the top of middle joint (2), with the place on the lower side, middle part of joint (4) slightly, is respectively flexibly connected one end of bracing wire (7).More than group forms a mechanical finger.Wherein, the bottom of the base pitch (1) of mechanical finger and the hydraulic press (hydraulic press of digging machine, remove scraper bowl) forearm (10) be fixedly connected with; forearm (10) is movably attached on large arm; the top of oil cylinder of small arm (9) is connected with forearm (10); between the middle joint (2) of the top of handgrip oil cylinder (8) and mechanical finger, with bracing wire (5) connect.Forearm can be fixedly connected with multiple mechanical fingers on (10), to form manipulator.

Operation principle: middle joint (2) and bracing wire coexist, and base pitch (1) is upper to be flexibly connected, but because the difference of position, the place on the upper side, middle part (with the tie point place of middle joint) of base pitch is to the distance at the top of base pitch, add the length of bracing wire (6), ability and sagacity equals middle joint (therefrom joint count with the place being connected of base pitch) to top, adds that the bottom junction of middle joint (with) of periproct arrives the mid point place on the lower side of the periproct junction of bracing wire 6 (with).So, work as rotating wheel disk, cover fork rotates, the rib tooth on cover fork cover carry-over bar, will make tooth bar move up and down time, bracing wire (5) also can move up and down, thereby pulls middle joint to move up and down.When central joint moves down, whole middle joint and periproct are along with middle joint moves down, but the top of base pitch not with middle joint and bracing wire (6) synchronizing moving, thereby make base pitch place on the upper side to this segment distance of base pitch top, and produce foldedly with its bracing wire (6), become more and turn back, so, the length of bracing wire (6), to the distance of base pitch, do not add the place on the upper side, middle part (with the tie point place of middle joint) of base pitch to the distance at the top of base pitch, thereby distance shortens.Therefore, in the process moving down at middle joint, bracing wire (6) can pull periproct, in the time that distance shortens, is bent downwardly movement along with moving down of middle joint.When periproct moves down, slightly joint also in like manner.Like this, whole mechanical finger is clenched fist with regard to turning-in.That is to say, in the time of grapple oil cylinder retrude, gripper of manipulator holds together; In the time that grapple oil cylinder protracts, manipulator struts.

Owing to adopting upper art design, make manipulator under the control of hydraulic press, grasp various objects.And can close up by multiple fingers, dig earth.

Brief description of the drawings

A kind of grapple full figure in Fig. 1.

Detailed description of the invention

In Fig. 1, the place on the upper side, middle part of base pitch (1), one end of joint (2) in flexible connection, the place on the upper side, middle part of middle joint (2), one end of flexible connection periproct (3), the place on the upper side, middle part of periproct (3), is flexibly connected slightly one end of joint (4).Base pitch (1) top, with the place on the lower side, middle part of periproct (3), be respectively flexibly connected one end of bracing wire (6), the top of middle joint (2), with the place on the lower side, middle part of joint (4) slightly, is respectively flexibly connected one end of bracing wire (7).More than group forms a mechanical finger.Wherein, the bottom of the base pitch (1) of mechanical finger is fixedly connected with the forearm (10) of hydraulic press; forearm (10) is movably attached on large arm; the top of oil cylinder of small arm (9) is connected with forearm (10); between the middle joint (2) of the top of handgrip oil cylinder (8) and mechanical finger, with bracing wire (5) connection.

Claims

1. a grapple, it is characterized in that: the place on the upper side, middle part of base pitch (1), one end of joint (2) in flexible connection, the place on the upper side, middle part of middle joint (2), be flexibly connected one end of periproct (3), the place on the upper side, middle part of periproct (3), be flexibly connected slightly one end of joint (4), base pitch (1) top, place on the lower side, middle part with periproct (3), each one end that is flexibly connected bracing wire (6), the top of middle joint (2), with the place on the lower side, middle part that slightly saves (4), each one end that is flexibly connected bracing wire (7), more than group forms a mechanical finger, wherein, the bottom of the base pitch (1) of mechanical finger is fixedly connected with the forearm (10) of hydraulic press, forearm (10) is movably attached on large arm, the top of oil cylinder of small arm (9) is connected with forearm (10), between the middle joint (2) of the top of handgrip oil cylinder (8) and mechanical finger, connect with bracing wire (5).
