Description

The cantilever crane device

Technical field

The utility model relates to mechanical equipment manufacturing technology field, particularly relates to a kind of cantilever crane device.

Background technology

In order to solve oil-well rig wellsite facility component inspection, the lifting problem during installation in order to improve operating efficiency, adopts cantilever crane to finish handling work mostly.But existing cantilever crane can only satisfy single little parts lifting, lifts narrow range, lifting weight is little, and rotational resistance is large, and damages easily.

The utility model content

The purpose of this utility model is to provide a kind of cantilever crane device, solve cantilever crane device of the prior art and can only satisfy single little parts lifting, lifting narrow range, lifting weight are little, and rotatable portion adopts sliding type, resistance is large, and holds damageable problem.

To achieve these goals, the technical solution adopted in the utility model is as follows:

The cantilever crane device comprises fixed mount, with the swivel mount that fixed mount is connected by radial bearing, and the cantilever beam that an end is flexibly connected by bearing pin and swivel mount, the pull bar that is connected by bearing pin with the other end of cantilever beam, and be arranged at and hang the thing device on the cantilever beam; The other end of described pull bar is connected with swivel mount by bearing pin.

In order to guarantee that the utility model can carry heavier object, also is provided with thrust baring between described fixed mount and the swivel mount.

Further, the described thing device that hangs is by telpher, the chain block that links to each other with telpher, and form by the suspension hook that chain links to each other with chain block, and telpher, chain block and suspension hook are structure as a whole.

Further again, the end that described cantilever beam links to each other with swivel mount also is provided with one and buckles, and this buckles by chain and links to each other with the swivel mount middle part.

Further, also be provided with chute on the described cantilever beam, described telpher is installed in the chute.

As a kind of preferred, the radial bearing between described swivel mount and the fixed mount is two, lays respectively at the two ends of swivel mount.

In addition, described pull bar forms by the connecting rod that is hinged and connected by two.

Compared with prior art, the utlity model has following advantage and beneficial effect:

(1) is provided with radial bearing and thrust baring between the utility model fixed mount and the swivel mount, so swivel mount can be realized the rotation of 360 degree, can either satisfies the heavier object of carrying, swivel mount is rotated flexibly;

(2) the utility model is provided with chain and pull bar between cantilever beam and swivel mount, thereby has guaranteed loading strength, has reduced again the flexure stress of cantilever beam, makes the utility model structure more reasonable;

(3) the utility model arranges two and hangs the thing device, can satisfy the different lifting demand of large equipment and smallclothes equipment, thereby make the utility model field of application wider, more can satisfy user's demand;

(4) the utility model can lift the workpiece weight within the specific limits, has greatly reduced carrying personnel's labour intensity, makes its lifting operation very convenient;

(5) the utility model is simple in structure, and manufacturing cost is lower, is easy to promote the use of.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Wherein, the parts name that mark is corresponding in the accompanying drawing is called: 1-fixed mount, 2-swivel mount, 3-cantilever beam, 4-pull bar, 5-telpher, 6-chain block, 7-suspension hook.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.

Embodiment

As shown in Figure 1, the cantilever crane device comprises fixed mount 1, the swivel mount 2 that is connected by radial bearing with fixed mount 1, the cantilever beam 3 that one end is flexibly connected by bearing pin and swivel mount 2, the pull bar 4 that is connected by bearing pin with the other end of cantilever beam 3, and two of being arranged on the cantilever beam 3 hang the thing device; The other end of described pull bar 4 is connected with swivel mount 2 by bearing pin.The above-mentioned thing device that hangs is by telpher 5, the chain block 6 that links to each other with telpher 5, and form by the suspension hook 7 that chain links to each other with chain block 6, and telpher 5, chain block 6 and suspension hook 7 are structure as a whole; Above-mentioned chain block 6 is also optional to be replaced with electric block.

In order to guarantee that the utility model can carry heavier object, so between described fixed mount 1 and swivel mount 2, also be provided with thrust baring.

In order to guarantee the loading strength of cantilever beam, reduce the flexure stress of cantilever beam, the end that described cantilever beam 3 links to each other with swivel mount 2 also is provided with one and buckles, and this buckles by chain and links to each other with swivel mount 2 middle parts.

In order to guarantee that telpher can regulate arbitrarily the position on cantilever beam, so also be provided with chute on described cantilever beam 3, described telpher 5 is installed in the chute.

For swivel mount can be rotated flexibly, as a kind of preferred, the radial bearing between described swivel mount 2 and the fixed mount 1 is two, lays respectively at the two ends of swivel mount 2.

In order to make the utility model when not needing to use, area occupied is less, so described pull bar 4 forms by the connecting rod that is hinged and connected by two.When not using, only need upwards lift cantilever beam then to fix with swivel mount and get final product, and are simple to operation.

According to above-described embodiment, just can realize well the utility model.
