Description

More changing device is supported in a kind of tool for crane commentaries on classics

Technical field

The utility model belongs to the crane gear technical field, relates to a kind of tool for crane commentaries on classics and supports more changing device.

Background technology

During the construction of modern land and marine oil field was produced, the equipment installation of the overwhelming majority needed to use in crane, especially the ocean platform production operation, and crane is the maximum equipment of frequency of utilization especially.In order to guarantee lifting safety, all crane gears make regular check on, safeguard and replacing seems particularly important.In the present engineering crane gear; The very general use pivoting support of crane is accomplished gyration as arm of derrick, but making regular check on of all pivoting supports is all very inconvenient, and carrying out once inspection comprehensively needs another crane to cooperate; If change operation then more inconvenient; Waste time and energy, inefficiency has increased the replacement cost safeguarded of crane rotation supporting.

Summary of the invention

The purpose of the utility model provides a kind of tool for crane commentaries on classics and supports more changing device, has solved when pivoting support is checked and safeguarded in the prior art, does not have suitable more changing device, the problem that takes time and effort.

The technical scheme that the utility model adopted is; More changing device is supported in a kind of tool for crane commentaries on classics; Comprise a track support, the track support upper surface is provided with detent holes, and detent holes is provided with detent mechanism; Detent mechanism is connected with the passing fluid cylinder that vertically is provided with, and passes fluid cylinder and is connected with the otic placode of snap ring;

The track support bottom is equipped with two groups of lift oil tanks and two groups of mechanic jacks; The lower end of every group of lift oil tank and mechanic jacks is arranged on the jack stand, is connected through a plurality of compensation linkages that tiltedly draw between two jack stands and the track support bottom;

Also comprise a pair of hydraulic jack that is arranged on the fixed body of bottom, this withstands on the surface, lower edge of top revolving body when hydraulic jack is worked.

The beneficial effect of the utility model is, need just can not carry out the replacing operation of pivoting support by second crane, improved the safety operation performance, practiced thrift cost, shortened the inspection maintenance time, improved operating efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model device embodiment;

The vertical view of Fig. 2 when to be the utility model device with pivoting support be drawn to inspection and change the position.

Among the figure, 1. hydraulic jack, 2. snap ring, 3. track support is 4. passed fluid cylinder; 5. detent mechanism, 6. oil circuit assembly, 7. jack stand, 8. compensation linkage, 9. lift oil tank; 10. mechanic jacks, revolving body on 11., 12. pivoting supports, 13. bottom fixed bodies, 14. arm supports.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

Like Fig. 1, Fig. 2; The structure of the utility model device is, comprises a track support 3, and track support 3 upper surfaces are provided with detent holes; Detent holes is provided with detent mechanism 5; Detent mechanism 5 is connected with the passing fluid cylinder 4 that vertically is provided with, and passes fluid cylinder 4 and is connected with the otic placode of snap ring 2, is sleeved on pivoting support 12 circumference during snap ring 2 work;

Track support 3 bottoms are equipped with two groups of lift oil tanks 9 and two groups of mechanic jacks 10; The lower end of every group of lift oil tank 9 and mechanic jacks 10 is arranged on the jack stand 7; Be connected through a plurality of compensation linkages that tiltedly draw 8 between two jack stands 7 and track support 3 bottoms; Thereby to crane bottom fixed body 13 conditional situation in certain height difference or the subrange is arranged, realize track support 3 adjusting within a certain height;

Also comprise a pair of hydraulic jack 1 that is arranged on the bottom fixed body 13; This withstands on the surface, lower edge of top revolving body 11 when hydraulic jack 1 is worked; Realization is to the jacking and the decline effect of top revolving body 11; Two hydraulic jack 1, pass fluid cylinder 4, two lift oil tanks 9 all are connected with oil circuit assembly 6, accept oil circuit assembly 6 unify control.

Like Fig. 2, the internal diameter of snap ring 2 and pivoting support 12 external diameters coupling is used for pivoting support 12 suits are blocked, and snap ring 2 is provided with otic placode, is used for and being connected of passing fluid cylinder 4.Track support 3 is provided with detent holes, under the effect of passing fluid cylinder 4, can progressively pivoting support 12 be shifted out from former installation site through the mutual draw between detent mechanism 5 and the detent holes.

The use of the utility model device is:

1) elder generation lies in a horizontal plane in the arm of derrick of crane on the arm support 14; Use then lift oil tank 9 that oil circuit assembly 6 control is installed on track support 3 bottoms with track support 3 jack-up behind assigned address; With the locking of mechanic jacks 10 jack-up, it is firm that compensation linkage 8 is connected; The specified location of fixed body 13 left and right sides is installed two hydraulic jack 1 in the crane bottom, through 1 effect of jacking simultaneously of two hydraulic jack, with crane top revolving body 11 jack-up, pivoting support 12 is separated with the crane body.

2) snap ring 2 is stuck on pivoting support 12 circumference; Action through the control passing fluid cylinder that is connected with snap ring 24 and detent mechanism 5; Pivoting support 12 is drawn out on the track support 3, checks maintenance or replacing, after the completion pivoting support 12 is passed back original position.

3) again with 1 release simultaneously of two hydraulic jack, crane top revolving body 11 is put down, pivoting support 12 and crane body cover are connected, promptly accomplish the inspection maintenance or the replacing of pivoting support 12.

More changing device is supported in the tool for crane commentaries on classics of the utility model; Be applicable to that all types of land of using pivoting support to accomplish the arm gyration are with crane and ocean platform crane; Solved existing crane rotation supporting and changed the complicated a series of problems of operation, improved the safety operation performance, saved the activity duration.
