Abstract
The invention provides a structure of a lifting arm of a crane, which is capable of effectively reducing the size of the lifting arm during transportation, facilitating transportation, and ensuringfast and convenient mounting. The lifting arm comprises an upper arm and a lower arm, and is characterized in that the lower end of the upper arm is pivoted with the upper end of the lower arm; an accommodating groove is formed in the lower arm in the length direction of the lower arm; the upper arm can be accommodated in the accommodating groove; support arms are symmetrically pivoted with two sides in the middle of the upper arm; the lower end of each support arm is connected with a limiting shaft via a fixing shaft; a chute extending downwards is formed in the lower arm; a plurality of limiting and clamping grooves are formed in the side, far away from the support arms, of the chute in an outwards protruding manner; a plurality of fixing holes are formed in the side, near the support arms, of the lower arm; the fixing shaft is mounted in one fixing hole; and the limiting shaft can slide up and down in the chute, and is clamped in one limiting and clamping groove.
Description
Technical field
The present invention relates to technical field of crane equipment peculiar to vessel, be specifically related to the structure of the arm that foreign material hang.
Background technology
Zones of different at boats and ships is provided with the crane gear of various different model, and these crane gears select different model specifications according to the demand of transport goods and materials, are referred to as foreign material and hang. The arm that existing foreign material hang includes upper arm, underarm and connects the linking arm of upper arm, underarm, and linking arm is bending, and upper arm, underarm and linking arm are fixedly connected by welding, and the arm volume after welding is big, transport inconvenience.
Summary of the invention
For the problems referred to above, the invention provides the structure of the arm that foreign material hang, it can effectively reduce shared volume during transport, it is simple to transport, and convenience quick for installation.
Its technical scheme is such, including upper arm and underarm, it is characterized in that: the lower end of described upper arm is articulated in described underarm upper end, described underarm is provided with storage tank along its length, described upper arm can be contained in described storage tank, it is pivoted with support arm to the lateral symmetry of described upper arm middle part, the lower end of supported on both sides arm connects respectively through fixing axle and limit shaft, described underarm is provided with the chute downwardly extended, described chute is provided with some spacing draw-in grooves away from the side convex of described support arm, the side of the contiguous described support arm of described underarm is provided with some fixing holes, described fixing axle is installed in described fixing hole, described limit shaft can slide up and down along described chute, and be installed in described spacing draw-in groove.
It is further characterized by
Being connected with mounting blocks on described underarm, described mounting blocks is fixed with reinforcement plate, described reinforcement plate bottom is provided with orthogonal backing plate.
After adopting the structure of the present invention, it has the beneficial effects that: the lower end of upper arm is articulated in underarm upper end, underarm is provided with storage tank along its length, upper arm can be contained in storage tank, it can effectively reduce arm volume, it is readily transported, it is pivoted with support arm to the lateral symmetry of upper arm middle part simultaneously, the lower end of supported on both sides arm connects respectively through fixing axle and limit shaft, underarm is provided with the chute downwardly extended, chute is provided with some spacing draw-in grooves away from the side convex of support arm, the side of the contiguous support arm of underarm is provided with some fixing holes, fixing axle is installed in fixing hole, limit shaft can slide up and down along chute, and it is installed in spacing draw-in groove, its dismounting, easy for installation, underarm is connected with mounting blocks, mounting blocks is fixed with reinforcement plate, strengthen plate bottom and be provided with orthogonal backing plate, it can be ensured that the integrally-built stability of arm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
