Abstract
The utility model discloses a balance mechanism of a crane, and aims to provide the balance mechanism of the crane, which has a simple structure, and has a pin roll which is only stressed by extrusion force. The technical scheme for realizing the purpose of the utility model is that: the balance mechanism of the crane comprises a trolley, a ground beam and a hinged shaft, wherein inner surfaces of an upper hinged support and a lower hinged support are respectively provided with a lateral arc groove to be rotatably matched with the hinged shaft, a clearance is left between the two end surfaces of the arc grooves of the upper and the lower hinged supports, the outer surfaces of the upper and the lower hinged supports are respectively provided with a connection plate, the upper connection plate is connected with the ground beam, a balance beam or a ground jack, and the lower connection plate is connected with a traveling crane rack. Compared with the prior art, the utility model has the advantages of having a simple structure and the pin roll which is only stressed by the extrusion force, so materials are saved.
Description
Technical field:
The utility model relates to the equalizing gear of a kind of hoisting crane, particularly a kind of hoisting crane.
Background technology:
Crane is on ground rail in the operational process, because the injustice on basis, ground, the deformation force that the connection of operation chassis grade beam, equalizing bar or supporting leg is produced has the effect of destruction to parts, currently used structure be the operation chassis be that bearing pin is connected with the connection of grade beam, equalizing bar or supporting leg, above-mentioned deformation force produces shearing force to bearing pin, thereby bearing pin need make the major diameter bearing pin, and its complex structure, consumptive material are many.
Summary of the invention:
The purpose of this utility model provides a kind of equalizing gear of simple in structure, a kind of hoisting crane that bearing pin only is squeezed the power effect.The technical scheme that realizes the utility model purpose is, a kind of equalizing gear of hoisting crane, comprise chassis, grade beam and hinge, it is characterized in that: the inside face of upper and lower free bearing respectively is provided with a horizontal deep-slotted chip breaker and a hinge commentaries on classics and joins, gapped between the both sides end face of upper and lower free bearing deep-slotted chip breaker, the outside face of upper and lower free bearing is provided with connecting panel, and upper junction plate is connected with grade beam, equalizing bar or supporting leg, and lower connecting plate is connected with the driving stand.The advantage that the utility model has compared with the prior art is simple in structure, bearing pin only is subjected to effect of radial compression power thereby saving in material.
Description of drawings:
Fig. 1 is a front view of the present utility model; Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
The utility model has following examples, the inside face of two relative upper and lower free bearings 6,4 is provided with the groove that horizontal cross section is an arc, hinge 5 is transferred in the deep-slotted chip breaker of above-mentioned upper and lower free bearing, respectively be provided with upper and lower connecting panel 7,3 on the outside face of upper and lower free bearing, described upper junction plate 7 is connected with grade beam 8, equalizing bar or supporting leg, described lower connecting plate is connected with the operation stand, and left and right sides end cap 9 makes it to fuse at the hinge two ends by screw retention.When on uneven road surface 1, the walk swing of time generation of driving stand 2, to swing on the hinge side face by upper and lower hinge plate and to carry out balance, hinge only is subjected to radial compression applied, and does not have shear action, thereby the diameter of hinge can be less.
