Technical field

The utility model relates to a kind of mechanical arm, especially a kind of energy-saving machinery arm that adopts intersection lever contracting mechanism.

Background technology

As shown in Figure 1, conventional Joint Manipulator is comprised of a plurality of arms that connect by joint, under extended configuration, when capturing the distance of object distance abscission joint, close festival-gathering and bear huge load, capture heavier article and can cause joint to receive damage, therefore, the job area of Joint Manipulator and operation weight capacity are received serious restriction.

Utility model content

For overcoming the deficiencies in the prior art, the utility model provides the energy-saving machinery arm that a kind of job area is wide, operation weight capacity is large.

The technical scheme that the utility model is taked is: a kind of energy-saving machinery arm, comprise column, two slide blocks and the lever group of intersecting, described column is provided with sliding rail, described slide block can slide up and down at sliding rail, the lever group of intersecting is comprised of many groups of intersection levers, and described intersection lever is the lever that two middle parts are flexibly connected, and intersects and by lever end, is flexibly connected between lever, one end of intersection lever group is connected with two slide blocks, and the other end connects grabbing device.

As the preferred technical scheme of the utility model, also comprise upright post base and base joint, between upright post base and column, by base joint, be connected, column can rotate relative to upright post base.

As the preferred technical scheme of the utility model, also comprise counter weight construction, described column inner hollow, described counter weight construction comprises pulley, flexible connecting member and balancing weight, and described pulley is located at column top, and flexible connecting member strides across from pulley, flexible connecting member one end connects any arbitrary position of two slide blocks being arranged on sliding rail, the other end connects balancing weight, and described balancing weight is positioned at the hollow space of column, not with column sidewall contact.

As the preferred technical scheme of the utility model, described pulley comprises the first pulley and the second pulley, and the first pulley is located on the sidewall at column top, and the second pulley is located at column top center, and flexible connecting member strides across the first pulley and the second pulley successively.

As the preferred technical scheme of the utility model, described flexible connecting member is rope or chain.

As the preferred technical scheme of the utility model, also comprise cradle head, the other end of described intersection lever group is connected with grabbing device by cradle head.

As the preferred technical scheme of the utility model, also comprise power part, described power part is used for controlling two slide blocks and does identical or rightabout sliding up and down at sliding rail.

The telescoping mechanism of energy-saving machinery arm of the present utility model adopts and intersects lever group structure, and due to intersect two slide blocks that lever group is connected all force-applied, the load pressure of energy-saving machinery arm supports as the strong point by two slide blocks, so can bear very large load; And intersect lever group and by many groups, intersect levers and form, there is larger flexible scope, can heavily loaded operation on a large scale in, and also owing to intersecting the structure of lever, energy-saving machinery arm has less size, convenient working and transportation after stretching; Be provided with counter weight construction, weight and the balancing weight of intersection lever group and slide block, grabbing device and cradle head are cancelled each other, while therefore working, the power part of energy-saving machinery arm bears the mass loading of intersection lever group and slide block, grabbing device and cradle head self hardly, only bear the load from manipulating object (crawl thing), the workload that has greatly reduced energy-saving machinery arm power part, can significantly reduce energy consumption.

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is done further and illustrated.

The specific embodiment

embodiment 1

This automatic energy saving machinery arm, comprise column 1, two slide blocks 2 and the lever group 3 of intersecting, described column 1 is provided with sliding rail 4, described slide block 2 can slide up and down at sliding rail 4, the lever group 3 of intersecting is comprised of many groups of intersection levers, and described intersection lever is the lever that two middle parts are flexibly connected, and intersects and by lever end, is flexibly connected between lever, one end of intersection lever group 3 is connected with two slide blocks 2, and the other end directly connects grabbing device or connects grabbing device by cradle head.Also comprise upright post base 5 and base joint 6, between upright post base 5 and column 1, by base joint 6, be connected, column 1 can rotate relative to upright post base 5.Also comprise counter weight construction, column 1 inner hollow, counter weight construction comprises pulley, flexible connecting member (rope) 7 and balancing weight 8, pulley comprises the first pulley 9 and the second pulley 10, the first pulley 9 is located on the sidewall at column top, the second pulley 10 is located at column top center, rope 7 strides across the first pulley 9 and the second pulley 10 successively, rope 7 one end connect the slide block 2 that is positioned at sliding rail 4 upper ends, the other end connects balancing weight 8, balancing weight 8 is positioned at the hollow space of column, not with column 1 sidewall contact.
