Abstract
The utility model relates to an automatic hydraulic device for mounting and detaching pins, which is composed of a jack, a fulcrum body, an operating mechanism, a main pin, an auxiliary pin and a suspending and pulling device. A cylinder block (10) is connected with the fulcrum body (25), and the other end surface of the fulcrum body is connected with a standard section (39), a main pin body (40), an outer boosting device, suspending components (20, 22, 24), etc. to form an external main structure. The fulcrum body is provided with a plunger structure (11), a main pull rod (27), an auxiliary pull rod (29), etc. to form an integral structure of an automatic hydraulic device for mounting and detaching pins. The utility model overcomes the disadvantages of time waste and labor waste of manual disassembly, raises the construction progress, realizes the quick installation, and has convenience and simple operation.
Description
The utility model relates to the common mechanical field of engineering technology.
One of lifting device that construction must be used is a tower crane.In its installation, particularly unloading process, with manually finishing.It is time-consuming relatively to require great effort, and incurs loss through delay the duration.
The purpose of this utility model is to provide a kind of easy instrument, and promptly the automatic pin stripping attachment of hydraulic pressure is installed, dismantled the tower crane pin, thereby improves installing/dismounting speed to substitute manually.
The technical scheme that the utility model adopted is:
Connect supporting point body (25) by cylinder body (10), the other end of supporting point body connects standard knot (39), stub body (40), applied force device (46), and suspender (20,22,24) and other annex, form outside main structure, be provided with piston structure (11), main tie (27), subtie parts such as (29) in this body, constitute the overall structure of the automatic pin stripping attachment of hydraulic pressure.
The outside of cylinder body (10) connects handgrip (1), main fuel feed pump (2), secondary fuel feed pump (3), screw rod (4,5), nut (6,7), oil pipe liptinite (8), elbow inlet (9,12).
The outside attended operation bar (32) of supporting point body (25).
Cylinder body (10) and supporting point body (25) are by screw rod (15,16,21,26), and nut (13,14,23,29), steel plate (19,28) butt joint are for one.
Flexibly connect a piston (11) in cylinder body (10) and the inner chamber after supporting point body (25) is docked, by the fixedly connected main tie of piston (27), subtie (29), clamping plate (36).
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the automatic pin installing/dismounting of hydraulic pressure device;
Fig. 2 is the cylinder body cutaway view;
Fig. 3 is the supporting point body structure chart;
Fig. 4 is the cutaway view of main tie;
Fig. 5 is the structure chart of standard knot.
The operator of the automatic pin installing/dismounting of hydraulic pressure device is 1, in construction is produced for being operating personnel's convenient settings of working, hydraulic oil pipe the 2, the 3rd, the asphalt channel when jack is worked, the effect of screw rod 4,5 is to spin mutually with nut, the fixing operation handgrip.Fixedly locknut 6,7 is fixedly welded on the hydraulic cylinder, and its working method is the same with screw rod 4,5.The oil pipe held stationary is sat 8 and is played the effect of stablizing two oil pipes, is welded on the cylinder body, with the protection oil pipe.Elbow 9 plays oil circuit and the interior mediation effect that is connected of cylinder, and is welded as a whole with cylinder body.Cylinder body 10 is used for stores hydraulic pressure oil.Piston 11 is installed in the cylinder body; Oil pipe elbow 12 is fixedly welded on the cylinder body.Stabilising arrangement 17 is fixedly mounted on the cylinder body upper end, plays and stablizes pull bar and prevent the effect that oil leaks outside.Piston pair pull bar 27 is installed in the piston main tie.
Attaching nut 23,30 can connect other member, and it is welded on the supporting point body.19,28 connect steel plate, and its effect is that two members are combined by connecting steel plate; Supporting point body 32 is the effect members when the very heavy power that has the opposite effect when being pulled in work.36 is the fulcrum breach, must be provided with during operation, is to be provided with in the lower end of fulcrum.
Operating means is installed on the dismounting fulcrum, and 29 connect negative part pin, and its effect has been the connection effect.
The formation of master pin: be provided with connecting hole, 33 are raise-position backstop, and its effect is not allow stub cross this position when work.35 is the pinhole of standard knot and the fish platee pinhole of standard knot; Stressed district when stub body 38 is master pin work; Insurance is inserted stub safety plug 40 in the hole 39, to prevent the work shift of master pin.The 41st, the fulcrum location of master pin applied force; 42 is the master pin connecting hole, is the special-purpose pinholes of the interconnective clamping plate of master pin and other member; Stub connecting cleat 43 is connected one with stub.
The Suspension hanger device, Suspension hanger spring 24 is one, is used for adjusting workload up and down; Direction adjusting apparatus 20 is adjusted direction at any time according to need of work, and certain randomness is arranged; 22 is the main part of suspension apparatus, plays the effect of suspension and coarse regulation.
Said structure has been realized the purpose of Fast Installation dismounting pin, thereby has been improved construction speed, and simple to operation.
