Abstract
The utility model provides a kind of for dragging the hydraulic jack device of sled, comprises supporting seat, hydraulic ram, fluid cylinder bearing, drags sled bearing, pipe link etc.Cylinder body of hydraulic oil cylinder and fluid cylinder bearing are hinged by otic placode, hydraulic cylinder piston rod and supporting seat hinged, pipe link one end is hinged on drags on sled, and the other end is hinged on supporting seat.Fluid cylinder bearing with drag that prize bearing reliable by pinned connection, drag and prize bearing and be welded on and drag on sled.Hydraulic ram jack-up under hydraulic action drags sled to predetermined altitude to realize the connection with trailer, and sled is dragged in pulling under the effect of pipe link, prevent the effect due to jacking force of inertia from making to drag sled miles of relative movement excessive or too small, enable hydraulic ram all the time vertical jack-up drag sled.During short range transport, the welded chain be welded on supporting seat hangs on fluid cylinder bearing, and protection supporting seat and piston rod drop due to the unexpected venting of hydraulic pressure.During long-distance transportation, supporting seat, fluid cylinder bearing, pipe link and hydraulic ram can be overall from dragging sled dismounting, constriction car load width, thus the current facility improving vehicle.
Description
Technical field
The utility model relates to a kind of for dragging the hydraulic jack device of sled, particularly relates to a kind of hydraulic jack device of the semi-trailer for oil field rapid transporting.
Background technology
Hydraulic jack is used in and drags in sled, and to be tractor truck be connected needs and prop up accessory equipment when dragging sled with dragging to prize, and hydraulic jack can regulate according to the height of trailer traction seat the height dragging and prize and tow the head in real time, to realize dragging sled to be connected with any of trailer.Hydraulic jack is primarily of compositions such as supporting seat, hydraulic ram, fluid cylinder bearings, but at present for dragging the jack device of sled, especially in the middle of the operation of well site of oil field rapid transporting, there is hydraulic ram when jack-up drags sled vehicle frame, due to the effect of inertia, and cause dragging sled miles of relative movement excessive, thus cause the oblique jack-up of jack device hydraulic ram, reduce the service life of hydraulic jack.And hydraulic jack is positioned at the both sides of dragging sled, what sled movement was dragged in wellsite operation is all main equipment, when long distance transportation, can affect normal transport because of the ultra-wide of vehicle.
Summary of the invention
The utility model is for the deficiency of above hydraulic jack, and design a kind of brand-new hydraulic jack device, this hydraulic jack device can realize vertical jacking and drag sled, and also can realize random exchange and the dismounting of hydraulic jack, its technical scheme adopted is as follows:
Hydraulic jack device, mainly comprises pipe link, supporting seat, drags sled bearing, hydraulic ram, fluid cylinder bearing and various connection bearing pins etc.Hydraulic ram comprises cylinder body and piston rod, piston rod under hydraulic action can in cylinder body free-extension, cylinder body and fluid cylinder bearing are hinged by otic placode, piston-rod lower end and supporting seat hinged.Pipe link one end drags the rotating shaft on sled hinged with being welded in, the other end and supporting seat hinged.
Described supporting seat is welded with chain, when dragging sled to carry out short range transition movement, hydraulic cylinder piston rod is retracted, supporting seat and pipe link is driven to retract, welded chain on supporting seat is hung on the hook of fluid cylinder bearing, prevents from causing due to the pressure sudden failure of hydraulic ram dropping of piston rod and supporting seat.
Fluid cylinder bearing described above, and drags that to prize bearing reliable by pinned connection, drags sled bearing to be welded in and drags on sled.During remote movement, can pull down jack device, constriction drags the width of sled, improves the current facility of vehicle.
Because the utility model have employed such scheme, supporting seat and piston rod hinged, when hydraulic oil enters the rod chamber of fluid cylinder, supporting seat seat is on solid ground, cylinder body takes up fluid cylinder bearing under pressure, thus drive drags sled to rise, concrete hoisting position is determined by the drawing head height of trailer, and owing to dragging the effect of inertia of sled trailing wheel, trailing wheel can move toward the direction of supporting seat, in order to prevent the distance of movement excessive or too small, sled is dragged in the pulling of can taking advantage of a situation of the pipe link on supporting seat, and hydraulic ram is ensured all the time, and vertical direction jack-up drags sled.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, but the utility model is not limited to following examples.
Fig. 1 is the typical structure front view of hydraulic jack device;
Fig. 2 is the typical structure birds-eye view of hydraulic jack device;
Fig. 3 is the typical structure left view of hydraulic jack device;
Fig. 4 is the state of hydraulic jack jack-up when dragging sled.
Nomenclature:
1-connecting rod axle bed, 2-pipe link, 3-hydraulic ram, 4-otic placode, 5-links up with, and 6-welded chain, 7-drags sled, 8-supporting seat, and 9-fluid cylinder bearing, 10-drags sled bearing
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, this example comprises pipe link 2, supporting seat 8, fluid cylinder bearing 9, otic placode 4 and hydraulic ram 3 etc.Cylinder body and the fluid cylinder bearing 9 of hydraulic ram 3 are hinged by otic placode 4, and wherein otic placode 4 is reliable by Bolt Connection with fluid cylinder bearing 9.The piston rod of hydraulic ram 3 and supporting seat 8 are by hinge, and pipe link 2 one end drags the connecting rod axle bed 1 on sled 7 hinged with being welded in, and one end and supporting seat 8 pass through hinge.Welded chain 6 is welded on supporting seat 8, and hook 5 is welded on fluid cylinder bearing 9.Fluid cylinder bearing 9 with drag that to prize bearing 10 reliable by pinned connection.
When dragging sled 7 to be connected with trailer, the piston rod of hydraulic ram 3 can under the effect of hydraulic pressure in cylinder body free-extension, supporting seat drops on for 8 times on solid ground, now under the continuation effect of hydraulic pressure, drag sled 7 to rise to predetermined height, pipe link 2 is held and is dragged sled 7 to realize the vertical jacking of hydraulic ram 3.In oil field closely operation transition time, supporting seat 8 is packed up along with the piston rod of hydraulic ram 3, and welded chain 6 is hung on hook 5, and protection supporting seat 8 prevents from dropping.During remote transition operation, laying down fluid cylinder bearing 9 and drag the connection bearing pin prizing bearing 10, fluid cylinder bearing 9, hydraulic ram 3, supporting seat 8 and pipe link 2 entirety can be dismantled from dragging sled 7, the narrowed width of trailer, the transport improving vehicle is current convenient.
