Abstract

The utility model relates to a mobile jack base used for placing a jack. The utility model is mainly characterized in that the chassis frame has a box shape structure, a set of rollers are arranged at the bottom of both side walls of the box shape frame (1) whose upper part and lower part is bottomless, roller ends of rollers are provided with mutually meshed driving gears (12), and the rollers are driven to roll by a worm gear. The interior of the box shape frame (1) is provided with a shelf (3) used for placing a jack (2), and both sides of the shelf are respectively provided with a connecting socket (5) used for connecting and fixing a multisection type supporting bar (4). Weight lifting and weight bearing movement can be realized by the utility model simultaneously, the utility model is suitable for vehicle maintenance, can be used as a tool in association with the vehicle, and the overnight security of a lifted heavy vehicle can be ensured. When the vehicle is stuck into mud particularly, the utility model can be used for self-help and excluding dilemma by a driver.

Description

Mobile jack base

The utility model relates to lifting gear, is a kind of very heavy base.

The base of existing jack is a flat board or a waggon formula base that fuses with jack.Jack with these bases can only play the effect of rising weight, and the height that rises also is subjected to the restriction of jack push rod length.In actual life, need a kind of can playing the weight jacking, have the instrument of this weight ability of moving again, for example, when automobile is absorbed in mud ground, need get up its jacking and make it to move to leave mud ground, this can utilize crane that automobile is escaped danger certainly, relies on extraneous strength but this need get in touch with, if running car is in the wild country, deserted mountain, for the moment be difficult to obtain relief, just can only hope sky heave a sigh, cause very big difficulty to chaufeur.So, a kind of instrument of saving oneself preferably can be arranged.Also have certain situation to be, some weight need be maked somebody a mere figurehead and be laid, and spends the night as autotruck is preferably built on stilts, existing method is to jack-up to spend the night, but built on stilts like this loaded vehicle is not too safe, if jack leakage of oil or stolen jack by the misdemeanant just can not reach the purpose of making somebody a mere figurehead loaded vehicle.

The purpose of this utility model provides a kind of and the supporting portable jack base of jack, jack is placed on this base moving this base after the weight jack-up, make it to move together with jack and weight thereof, or directly supporting weight with this base behind the jack stand weight.

The technical solution of the utility model that realizes above-mentioned purpose is, on one, the box frame bottom of not having the end down is provided with one group of roller groups that comprises land roller bearing and transition roller bearing, the roller bearing that lands is alternate with the transition roller bearing arranges side by side, the journal rest of each roller bearing is in the axis hole of bottom, box frame two side, and be fixed with transmission gear stretching the axle head of putting outside sidewall, the gear of every adjacent roller bearing axle head intermeshes, first roller bearing at one end is provided with a worm gear with power worm mesh again, in addition, be provided with one in the box frame in order to place the shelf of jack, respectively be provided with the fixing connection pole socket of more piece strut bar in the both sides of this shelf.

Aforesaid jack base after also jacking plays weight on the shelf that jack is placed in the box frame, is fastened on strut bar on the connection pole socket, and makes it to support simultaneously weight, and then weight is by jack and two strut bar while jack-up.At this moment, rotatable worm screw, then the worm gear with worm mesh rotates first roller bearing, because these roller bearing two ends all are provided with and adjacent shaft gear mating gear, and the gear on each adjacent roller bearing all intermeshes, then the rotation of first roller bearing promptly drives all roller bearings and all rolls the purpose that the realization jack base bears a heavy burden and moves forward.If the utility model is removed jack after holding the top weight with jack rising weight and with two strut bars, at this moment, weight can all hold the top by two strut bars, built on stilts the spending the night or the left alone without help purpose of putting of vehicle safety of realization loaded vehicle safety.

Therefore the utility model has been realized not only jacking weight but also the mobile purpose of bearing a heavy burden.The utility model can be made assembled structure, as driver's tool, so the good assistant of particularly long-distance driving chaufeur.Strut bar of the present utility model is a kind of multi-section type structure, can be as required spreading arbitrarily, also can raise arbitrarily and the long-term weight that supports, this has just made things convenient for the repairing work such as vehicle.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described specifically.

Description of drawings:

Fig. 1 is vertical semisectional view of the present utility model.

Fig. 2 is a transverse sectional view of the present utility model.

See that by figure the embodiment of the utility model jack base includes a box frame 1, shelf 3 and roller groups.Box frame 1 is upper and lower all not to have the bottom surface, and the both end sides of shelf 3 respectively is provided with one and connects pole socket 5 in order to place the shelf 3 of jack 2 to put one within it in the middle of the portion, and this connects on pole socket 5 can be hinged with multi-section type strut bar 4.For operation easily is positioned at the oil circuit valve of jack bottom, present embodiment digs in the top of shelf 3 on the two side of box frame 1 and is provided with a slotted eye 11.See by figure, the bottom of box frame 1 is one group of traveling gear, they are one group of roller groups of being made up of land roller bearing 7,10 and transition roller bearing 9, roller bearing 7,10 and the 9 alternate settings of transition roller bearing land, the journal rest of each roller bearing 7,9,10 is in the axis hole of bottom, box frame 1 two side, its end was fixed with transmission gear 12 after axle journal passed axis hole on the sidewall, and the transmission gear 12 of adjacent roller bearing 7,9,10 axle heads intermeshes.First on the right side roller bearing 7 that lands is provided with a worm gear 8 that is meshed with worm screw 6 in the drawings.Roller groups traveling gear so, when starting worm screw 6 is rotated, the worm gear 8 that is engaged with promptly drives first roller bearing 7 of landing and rolls, and the gear transmission second of the gear of roller bearing 7 axle heads that land by the transition roller bearing 9 axle heads roller bearing that lands rolls, and drives to last roller bearing that lands successively and rolls.See that thus because starting worm screw 6 can make set roller bearing roll simultaneously, then whole base promptly bears a heavy burden and moves forward.
