Description
Technical field
A kind of crane arm of the utility model regains inhibiting device, belongs to technical field of crane equipment.
Background technology
Because hydraulic ram can not do spacing use, foldable arm lorry-mounted crane, under retracted state, must increase mechanical position limitation, slides up and down to limit arm.There is certain manufacturing deviation in each kinematic mechanism due to hoisting crane, so stop gear must possess certain manufacture deviation pardon.At present, existing position limiting structure on market, quite a few is that after general assembly, stop gear position is determined at scene, is unfavorable for conformability and the presentation quality of product.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind of inhibiting device be arranged on when hoisting crane is regained for arm, avoids arm to slide up and down.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of crane arm regains inhibiting device, comprise crane transverse beam, hoisting crane column, crane arm stop gear and swing arm, hoisting crane column bottom is fixedly mounted on the centre of crane transverse beam, the top of column and one end of swing arm are hinged, the other end of swing arm and one end of arm are hinged, and stop gear is made up of positioner and registration device two parts;
The positioner of described stop gear is fixedly mounted on the middle part of crane arm, the registration device of stop gear be fixedly mounted on hoisting crane column bottom and be positioned at crane arm up and down time its registration device track on.
The positioner of described stop gear is be fixedly mounted on spacing bearing pin in the middle part of crane arm by mount pad, and the registration device of described stop gear is that Z bar is welded on hoisting crane column bottom and forms a groove and this groove is corresponding with alignment pin.
Described spacing bearing pin is bolted on mount pad by multiple, and the bolt mounting holes that described mount pad is provided with multiple row multirow makes the installation site of spacing bearing pin adjustable.
The contact surface of described mount pad and spacing bearing pin is equipped with serrated reliefs.
The side of described spacing bearing pin is provided with multiple stay bearing plate.
The utility model compared with the existing technology has following beneficial effect.
1, the utility model in the middle part of arm and hoisting crane column bottom intersect certain a bit coordinate installation stop gear, carry out spacing to the nadir that arm is regained, avoid it to slide up and down.
2, the utility model is realized arm regained nadir limit function by coordinating of Z bar and position-limitting pin, and the groove that Z bar is welded on column has certain elasticity, makes it in spacing process, also have certain pooling feature.
3, on the mount pad of stop gear, be provided with multiple row multirow bolt mounting holes in the utility model, make the installation site of spacing bearing pin adjustable, realize the containing of stop gear to manufacture deviation, enhance the conformability that product is installed.
The contact surface of the mount pad 5, in the utility model and spacing bearing pin is equipped with serrated reliefs, and strengthen friction force between the two, reliably stressed, multiple stay bearing plates of alignment pin side also ensure that the reliability of stop gear.

In figure: 1 is crane transverse beam, 2 is hoisting crane column, and 3 is crane arm, and 4 is stop gear, and 5 is swing arm, and 6 is mount pad, and 7 is spacing bearing pin, and 8 is Z bar, and 12 is stay bearing plate.
Detailed description of the invention
As shown in figures 1 to 6, a kind of crane arm of the utility model regains inhibiting device, comprise crane transverse beam 1, hoisting crane column 2, crane arm 3 stop gear 4 and swing arm 5, hoisting crane column 2 bottom is fixedly mounted on the centre of crane transverse beam 1, the top of column 2 and one end of swing arm 5 are hinged, the other end of swing arm 5 and one end of arm 3 are hinged, and stop gear 4 is made up of positioner and registration device two parts;
The positioner of described stop gear 4 is fixedly mounted on the middle part of crane arm 3, the registration device of stop gear 4 be fixedly mounted on hoisting crane column 2 bottom and be positioned at crane arm 3 up and down time its registration device track on.
The positioner of described stop gear 4 is be fixedly mounted on spacing bearing pin 7 in the middle part of crane arm 3 by mount pad 6, and the registration device of described stop gear 4 is that Z bar 8 is welded on and forms a groove bottom hoisting crane column 2 and this groove is corresponding with alignment pin 7.
Described spacing bearing pin 7 is bolted on mount pad 6 by multiple, and the bolt mounting holes that described mount pad 6 is provided with multiple row multirow makes the installation site of spacing bearing pin 7 adjustable.
Described mount pad 6 and the contact surface of spacing bearing pin 7 are equipped with serrated reliefs.
The side of described spacing bearing pin 7 is provided with multiple stay bearing plate 12.
When crane arm 3 in the utility model is recovered to off working state after work completes, when crane arm 3 drops to certain position, spacing bearing pin 7 on arm is stuck in the groove of Z bar 8 formation bottom hoisting crane column 2, crane arm 3 is stoped to continue to decline, play the effect that nadir is spacing, avoid it to slide up and down.
Above-mentioned mount pad 6 is provided with multiple row multirow bolt mounting holes, make spacing bearing pin 7 installation site adjustable, do not need scene to determine when mounted, only the position of alignment pin 7 need be carried out finely tuning, realize the containing of stop gear to manufacture deviation, enhance the conformability that product is installed.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.Such as, the Z bar 8 in the utility model and the commutative position of alignment pin 7 are installed, and change depending on actual needs.
