Abstract

The utility model discloses a mounting and fixing device for crane auxiliary arm, using the side plane of a big arm to fix to two dead plates which are provided with a sliding rail. The front and rear of the side of the auxiliary arm are correspondingly provided with two groups of rolling pulleys, wherein, two rolling pulleys in one group are axially moved in the sliding rail; two rolling pulleys in the other group are respectively rolled translationally on the surface of the dead plate. A positioning piece is used for limiting the movement distance of the rolling pulley to guarantee the positioning accuracy. The utility model respectively overcomes the outward and downward force moment of the auxiliary arm to achieve steady rolling. The mounting and fixing device of the crane auxiliary arm has the advantages of accurate and flexible installation; the motion is stable without impact and damage to the parts.

Description

Crane subsidiary arm is installed and anchor fitting
Technical field
The utility model relates to hoisting crane and other structures or part, specifically is that a kind of crane subsidiary arm is installed and anchor fitting.
Background technology
Because the hoisting crane operating mode constantly changes, often need Fast Installation or dismounting auxiliary in the work.There is following defective in existing auxiliary loading and unloading: (1) auxiliary bangs into big arm axle cover by the slip beat, very effort.(2) auxiliary is in the beat process, and the auxiliary center-of-gravity position is in continuous variation, causes auxiliary outward-dipping and the arm end is downward-sloping, causes the axis hole line of centers not overlap generation with big arm axle cover line of centers, and bearing pin enters after the part can't reentrant phenomenon, even perplexs.(3) auxiliary bangs into big arm axle cover by beat, and impulsive force is big, very easily causes damage parts, and structure precision is descended.
Summary of the invention
The purpose of this utility model provides a kind of fast speed crane subsidiary arm easy to use and installs and anchor fitting.
The technical solution of the utility model is to change existing auxiliary to bang into the mode that big arm axle overlaps by beat, is to utilize big arm side plane to be benchmark, and front and back are fixed two adapter plates respectively.Sliding rail is arranged on the adapter plate.Corresponding big arm restraining board position, each is equipped with two pairs of rolling pulleies respectively the auxiliary side, and wherein a pair of rolling pulley is for axial motion in the sliding rail of adapter plate, and another supplies to roll in the translation of adapter plate outside face to rolling pulley.The locating piece that inserts big arm axle cover for auxiliary axis hole location is housed at the adapter plate end that overlaps an end near big arm axle.Auxiliary earlier moves to locating piece to the forward position sliding rail by rolling pulley during installation, carries out big arm axle cover and the butt joint of auxiliary axis hole, inserts upper and lower two pivot pins, is that rotating shaft rotates to assigned position and fixes and get final product with these two pivot pins again.
The utlity model has following beneficial effect:
(1) this apparatus structure is simple, and is easy to make.
(2) adopt roll mode to replace the slip beat mode of background technology, overcome outside, the downward moment of auxiliary respectively, accomplish accurate positioning, flexible movements.
(3) time saving and energy saving, 1~2 people can operate.
(4) stable action does not have and impacts, and parts are not caused damage.
Description of drawings
Fig. 1 installs and the fixture structure schematic top plan view for the utility model crane subsidiary arm.
Fig. 2 is AA position left view (there is similar situation the BB position among Fig. 1) among Fig. 1.
Fig. 3 install for the utility model crane subsidiary arm and anchor fitting at the installation process scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The big arm side plane of the utility model utilization is benchmark, and front and back are fixed two adapter plates 3 and adapter plate 5 respectively, and sliding rail is all arranged on the adapter plate.Corresponding big arm restraining board position, each is equipped with two pairs of rolling pulleies 1 and rolling pulley 2 respectively the auxiliary side, one of them rolling pulley 1 is for axial motion in the sliding rail of adapter plate 3, and another rolling pulley 2 then axially moves in the sliding rail of adapter plate 5.Two rolling pulleies 2 roll at adapter plate 3 or adapter plate 5 outside face translations respectively.Like this, overcome the outside and downward moment of auxiliary respectively, reached the purpose of steady action.Overlapping 7 one ends near big arm axle the locating piece 4 that inserts big arm axles cover 7 for auxiliary axis hole 6 location be housed at adapter plate 3.Locating piece 4 has been used for limiting the miles of relative movement of rolling pulley 1, has guaranteed accuracy of positioning.

Claims (1)

1, a kind of crane subsidiary arm is installed and anchor fitting, comprises locating piece and rolling pulley, it is characterized in that utilize big arm side plane to be benchmark, front and back are fixed two adapter plates (3) and adapter plate (5) respectively, and sliding rail is arranged on the adapter plate; Corresponding big arm restraining board position, each is equipped with two pairs of rolling pulleies (1) and rolling pulley (2) respectively the auxiliary side, rolling pulley (1) is for axial motion in the sliding rail of adapter plate (3) or adapter plate (5), and rolling pulley (2) is for rolling at adapter plate (3) or adapter plate (5) outside face translation; Overlapping an end near big arm axle the locating piece (4) that inserts big arm axle covers (7) for auxiliary axis hole 6 location be housed at adapter plate (3).
