According to Fig. 1～Fig. 5, hydraulic lifting apparatus 1 of the present invention is made as portable manual small lifting means especially, and it has two-piston cylinder component 2, and they be arranged in parallel with respect to the stroke direction of being represented by double-head arrow 3.Each piston cylinder assembly 2 has a cylinder 4, is arranged on wherein at stroke direction 3 upper pistons 5 adjustablely.Its piston 5 and piston rod 6 are affixed to be connected particularly antitorquely.In a side that deviates from piston 5, its piston rod 6 stretches out its cylinder 4 and is bearing on the support base 7.For this reason, this support base 7 is connected with piston rod 6 antitorquely.
Its cylinder 4 has pilot sleeve 8 in the end towards support base 7, and it is axially directed on piston rod 6.Between pilot sleeve 8 and piston rod 6, keep as far as possible little diameter clearance, tilt with respect to piston rod 6 to avoid pilot sleeve 8.Its pilot sleeve 8 and and the cylinder end 9 that deviates from of support base 7 between, its cylinder 4 has diameter clearance with respect to piston rod 6, promptly outside pilot sleeve 8, forms endplay 10 between cylinder 4 and piston rod 6.Avoid wall contact between piston rod 6 and the cylinder 4 by this way.For this reason, piston 5 is provided with diameter clearance with respect to cylinder 4, so that can avoid owing to bigger wearing and tearing between piston 5 and cylinder 4 are tilted.When this scheme made that carrying out stroke between cylinder 4 and piston rod 6 regulates, cylinder 4 was finally by pilot sleeve 8 guiding.
Form a hydraulic cavities 11 between cylinder end 9 in cylinder 4 and the piston 5, it is communicated with a hydraulic joint 12.In another embodiment, its hydraulic joint 12 also can be arranged on other position.
With reference to Fig. 3～Fig. 5, between two cylinders 4 of two-piston cylinder component 2, a bridge spare 14 is set, it extends perpendicular to the longitudinal axis 13 with 13 longitudinal central axis lines of representing or cylinder 4.This bridge spare 14 is fixed on two cylinders 4 or on its pilot sleeve 8, particularly connects by corresponding weld seam 15.On its bridge spare 14, be provided with and promote lap plate 16.Same possible is by mono-block cast its pilot sleeve 8 to be formed with its bridge spare 14.
With reference to Fig. 5, it promotes lap plate 16 and is made of L shaped angle steel, it comprise the back of the body spare 17 parallel with stroke direction 3 and with back of the body part 17 perpendicular distal from load member 18.With load member 18 away from end, on its back of the body part 17, form a hook 19, by this hook its promote lap plate 16 be hooked to support base 7 away from the bridge spare of bridge spare 14 on the rib 20.For this reason, rib 20 has step 21 on this bridge spare.In the illustrated embodiment, its lifting lap plate 16 is made of independent member, and it can be hooked on the bridge spare 14 as required or pull down from it.The special advantage of this structure is that the lifting lap plate 16 that is worn can successfully change into new.In addition, can provide different types of lifting lap plate 16, they can use according to condition of service at that time.In addition, possible is to constitute bridge spare 14 like this, and promptly it promotes the different stroke positions that lap plate 16 can be fixed on bridge spare 14.For this reason, particularly bridge spare 14 can extend to the upper end of cylinder 4 always approximately.
The lifting lap plate 16 that is arranged on the bridge spare 14 is bearing on the bridge spare 14 by its back of the body part 17.According to Fig. 3, its bridge spare 14 is arranged between the cylinder 4 like this, and promptly it is fixed on the cylinder 4 or is fixed on respect to one another of its pilot sleeve 8.In addition, its position is selected like this, that is, make the back of the body spare 17 of lifting lap plate 16 disposed thereon protrude in cylinder 4 or its pilot sleeve 8 slightly in the direction of load member 18.In the embodiment of Fig. 1, the position of bridge spare 14 also can be selected like this, that is, make its back of the body part 17 not protrude in cylinder 4 or pilot sleeve 8 in the direction of load member 18.The special layout of its bridge spare 14, make its bont 1 by its piston cylinder assembly 2 can be closely with to promote weight approaching, therefore can avoid when promoting weight, producing the excessive arm of force and therefore produce excessive moment.
Piston 5 is bearing in the cylinder 4 with being rotated.In addition, its support base 7 constitutes like this, and promptly it is swung around cylinder longitudinal axis 13 when bridge spare 14 falls.Corresponding swing is adjusted among Fig. 3 to be represented with double-head arrow 22.Because each support base 7 is connected with corresponding piston bar 6 and a side of its piston rod is connected with respective pistons 5 antitorquely antitorquely, relative together with piston 5 cylinder 4 with piston rod 6 of each support base 7 is around axis of oscillation 13 swings.Such structure needn't be provided with additional supporting member or similarity piece, has just guaranteed the swing of support base 7.The swing of its support base 7 is particularly advantageous to be, can need not corresponding or suitable supporting be set or opening is set on weight so that promote lap plate 16 and promote the weight overlap joint for support base 7.
In the further special structure according to Fig. 1, be provided with on the cylinder end 9 that deviates from support base 7 and particularly weld a top board 23, it is used for additional or replaces promoting lap plate 16 to promote weight.This top board 23 can be pulled down or be inserted equally.In addition, its top board 23 can have shape such as the prismatic that is complementary with the weight that is promoted.Equally, can provide different types of top board 23, it uses according to corresponding condition of service.
The work of bont 1 of the present invention is as follows:
When piston 5 entered cylinder 4 fully, it promoted lap plate 16 and falls with the degree of maximum, promptly according to Fig. 1 its promote lap plate 16 by 7 of its load member 18 and support base on unshowned base or ground.Can arrange like this on the lifting weight that at its bont 1 of this position its load member 18 that promotes lap plate 16 maintains it from below and promotes weight.In case of necessity, its support base 7 must outwards or backward be arranged from promoting lap plate 16.Behind bont 1 location, apply hydraulic pressure.For this reason, two-piston cylinder component 2 parallel moving under hydraulic action.The hydraulic pressure of setting up in hydraulic cavities 11 makes cylinder 4 move and pass through bridge spare 14 in stroke direction 3 along piston rod 6 and makes that promoting lap plates 16 promotes.Because be subjected to two-piston cylinder component 2 parallel the moving of hydraulic action, its load is evenly distributed on two support base 7.
In addition, the weight that is carried by piston rod 6 relatively directly or with stroke direction 3 is supported by support base 7 abreast, has so further avoided curved load or moment in bont 1.Thus, bont 1 is relatively stable, thereby has improved the reliability that promotes overweight weight.
Another characteristics of bont 1 of the present invention are, if promote weight in a side by its bont 1, make its weight around with bont 1 away from balance staff swing, its bont 1 side direction is caught on weight, the load member 18 that promptly promotes lap plate 16 extends in parallel balance staff.For common bont, promoting or during the swing weight, it promotes lap plate upwards operation parallel to the ground, make it be resisted against on the end rib of the lifting lap plate load member of balance staff with respect to the weight of terrain slope by the swing effect.Its danger is that weight can slide from promoting lap plate.And bont of the present invention 1 different is because two-piston cylinder component 2 parallel moving under hydraulic action, promote or during the swing weight two-piston bar 6 realize different strokes.Make like this when promoting or swing, to change load member 18 or promote lap plate 16 that it promotes lap plate 16 and contacts with the weight face by its load member 18 with respect to ground-surface degree of dip.Another with balance staff away from piston cylinder assembly 2 further fall to making bont 1 relative vertical line inclination.Thus, support base 7 is with terrain slope and make bont 1 reliably stand, thereby has reduced weight from promoting the danger of landing on the lap plate 16.
Bont 1 structure relative compact of the present invention and make simple thus and be suitable for and carry.Simultaneously, bont 1 of the present invention weight 10 tons to 50 tons the weight for example that can promote the phase counterweight.
