Abstract
The utility model discloses a horizontal hydraulic jack with a self-locking device, and the utility model is especially suitable for inspecting and repairing a car or jacking a heavy object whose bottom keeps lower distance with a ground. The utility model is composed of a chassis, a scissors and fork type lifting frame, a self-locking supporting frame, a jacking oil cylinder, etc., wherein, the lifting frame is in a scissors and fork type structure, one end of the bottom surface of the lifting frame is hinged with the front end of the chassis, the other end of the lifting frame is hinged with the end of the piston rod of the jacking oil cylinder, the lifting frame is supported in a sliding chute through a shaft, and the sliding chute is arranged on the lateral plate of the chassis. The self-locking supporting frame is hinged on the lateral plate of the chassis and is arranged on the front end of the sliding chute, and a plurality of arc-shaped grooves are arranged on the self-locking supporting frame. The utility model is safe in use and is not necessarily provided with a ' jack supporting frame ' or wooden pegs, because the self-locking device is arranged on the utility model; besides, the utility model has the advantages of simple structure, small volume and light weight; while jacking objects with the same weight, the self weight of the utility model is only about 20 % of the self weight of an existing horizontal jack, and production cost is reduced.
Description
The utility model relates to a kind of jack, is specially adapted to car inspection and maintenance or top lifting bottom surface far from the lower weight of ground complementary space.
Common in the market horizontal jack, all be not with self-locking mechanism, when needing to prop up the top weight for a long time, for guaranteeing safety, also must be equipped with " very heavy support " or timber and support by top lifting thing, inconvenient operation, and volume is big, heaviness moves and carries inconvenience, is disclosed a kind of " band self-locking vertical lift hydraulic horizontal jack " in 87215784 at application number, though solved the problem of jack self-locking, but complex structure, the manufacturing cost height is again because crane arm is in cantilever position in the top lifting process, for making it that enough intensity be arranged, just need amplify or select for use the measured material of matter, not only increase manufacturing cost, and increase the deadweight of jack.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, alleviates deadweight significantly, is convenient to operation and carries, and the hydraulic horizontal jack of auto-lock function is arranged.
The utility model can reach by following measure, and as shown in the figure, the utility model is characterized in that hoisting rack adopts scissor structure by chassis, hoisting rack 1, form from lock support 2 and top lifting oil cylinder 3 etc., and its below one end and chassis front end are hinged.The other end is hinged with the top of piston rod 8 by axle 6, in axle 6 chutes 7 that then are supported on the side plate 4, be articulated on the side plate by axle 5 from lock support 2, and place axle 6 front end, have several deep-slotted chip breakers 9 from the inboard of lock support, be used for cooperating with axle 6, when piston rod 8 move ahead make hoisting rack rise to desired height by axle 6 after, in axle 6 grooves that just enter on lock support 2, prevent that hoist frame from falling after rise voluntarily, and ought be after hours, mention from lock support, after axle 6 and groove 9 are broken away from, turn the blowdown valve on the top lifting oil cylinder, hoist frame revert to original position under weight (power) effect.
Compared with prior art, the utility model is simple in structure, light, operation and easy to carry, particularly reduced raw-material consumption significantly, its manufacturing cost is reduced, as to produce a hoisting capacity be 3 tons jack, and deadweight of the present utility model has only 13 kilograms, and goes up the horizontal jack of L23 type that marine jack (group) company produces, hoisting capacity also is 3 tons, but its deadweight reaches 78 kilograms.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further, the selection of scantling of structure of the present utility model and material can be according to playing the liter weight design, deep-slotted chip breaker on lock support can be provided with as required, be advisable for general 3-5, in addition, for guaranteeing safe in operation, except that having from lock support, on the top lifting oil cylinder, also be provided with a limiting valve, the utility model can only be worked under specified load.
Claims (2)
1, a kind of hydraulic horizontal jack with self-locking device, it is characterized in that hoisting rack is a scissor structure by chassis, hoisting rack, form from lock support and top lifting oil cylinder etc., the end below it and the front end on chassis are hinged; The piston rod end of the other end and top lifting oil cylinder is hinged, and is supported in the chute on the tray side panel by axle; Be articulated on the tray side panel from lock support, place the front end of chute, have several deep-slotted chip breakers on it.
2, jack according to claim 1 is characterized in that the deep-slotted chip breaker on lock support has 3-5.
