Particularly, the utility model provides a kind of four post lifting machines, comprising:
Two bridge members, the place, the same side of said two bridge members has an access bridge member respectively;
Two cross members, said two cross members vertically are engaged in the place, two ends of said two bridge members respectively with the bearing of trend of said bridge member; And
Four columns, the two ends from said two cross members extend upward respectively;
Wherein, the upper surface place of said bridge member is provided with at least two holes, passes to allow a short rope;
Wherein, the inside at said bridge member two ends is equipped with short rope insurance roller, and the two ends of said short rope are connected to a short rope safety block via said short rope insurance roller.
According to a preferred embodiment of the present invention, in four above-mentioned post lifting machines, also comprise: the lifting wire rope group is arranged at the inside of said bridge member; And pneumatic shuttle, be connected with said lifting wire rope group.
According to a preferred embodiment of the present invention, in four above-mentioned post lifting machines, also comprise: the lifting wire rope group is arranged at the inside of said bridge member; And hydraulic efficiency gear, be connected with said lifting wire rope group.
According to a preferred embodiment of the present invention, in four above-mentioned post lifting machines, said lifting wire rope group is connected in said pneumatic shuttle via said short rope insurance roller.
According to a preferred embodiment of the present invention, in four above-mentioned post lifting machines, said lifting wire rope group is connected in said hydraulic efficiency gear via said short rope insurance roller.
In sum, the four post lifting functions of the utility model prevent that effectively the lifting machine descends suddenly when steel rope accidental or fracture, reduce the generation of contingency.
Should be appreciated that the above generality of the utility model is described and following detailed description all is exemplary and illustrative, and be intended to further explanation is provided for as claimed in claim the utility model.
Description of drawings
Accompanying drawing mainly is to be used to provide the utility model is further understood.Accompanying drawing shows the embodiment of the utility model, and plays the effect of explaining the utility model principle with this specification sheets.In the accompanying drawing:
Fig. 1 schematically shows the schematic structure of the four post lifting machines with parachute gear of the utility model.
The specific embodiment
Describe the technical scheme of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 schematically shows the schematic structure of the four post lifting machines with parachute gear of the utility model.As shown in the figure, the four post lifting machines of the utility model mainly comprise: bridge member 101, access bridge member 102, cross member 103, four columns 104, hole 105, short rope 106 and short rope insurance rollers 107.
In the embodiment shown in fig. 1, place, the same side of two bridge members 101 has an access bridge member 102 respectively.The tire of automobile both sides can be directly from this access bridge member 102 to whole bridge member 101, so that this four posts lifting machine lifts vehicle hoisting.
The bearing of trend with said bridge member 101 is vertical respectively for two cross members 103, and is engaged in the place, two ends of said two bridge members 101.Like this, then two across make up 103 just can constitute a square shape with two bridge members 101 together lifting platforms.This lifting platform can carry out up-and-down movement in vertical direction along four columns 104.These four columns 104 are arranged at the place, two ends of said two cross members 103 respectively, and extend upward from this position.
Particularly, according to the utility model, the upper surface place of bridge member 101 is provided with at least two holes 105, passes to allow a short rope 106, with reference to the bridge member 101 on the right side among the figure 1.
It should be noted that in the embodiment shown in fig. 1 shown in the bridge member 101 in left side is the inner structure of this bridge member 101, shown in the bridge member 101 on right side then is the outside face of this bridge member 101.
Forward the bridge member 101 in the left side among Fig. 1 now to, the inside at these bridge member 101 two ends is equipped with short rope insurance roller 107.Preferably, each end place of bridge member 101 all is provided with two short rope insurance rollers 107.Wherein, the two ends of said short rope 106 are connected to a short rope safety block (not shown) via said short rope insurance roller 107.
In addition, the four post lifting machines of the utility model also comprise a lifting wire rope group 108, and this lifting wire rope group 108 is arranged at the inside of said bridge member 101.In addition, an end of this lifting wire rope group 108 is fixed in column 104 places at said access bridge member 102 places, and the other end is connected to a pneumatic shuttle 109.Like this, just can carry out retractable operation, make that the lifting platform of whole square shape is up and down this lifting wire rope group 108 through this pneumatic shuttle 109.
Perhaps, the four post lifting machines of the utility model also can be the structures of a lifting wire rope group 108 and a hydraulic efficiency gear 110.This lifting wire rope group 108 is arranged at the inside of said bridge member 101.In addition, an end of this lifting wire rope group 108 is fixed in column 104 places at said access bridge member 102 places, and the other end is connected to this hydraulic efficiency gear 110.Like this, just can carry out retractable operation, make that the lifting platform of whole square shape is up and down this lifting wire rope group 108 through this hydraulic efficiency gear 110.
According to a preferred embodiment, lifting wire rope group 108 can be connected in pneumatic shuttle 109 or hydraulic efficiency gear 110 via short rope insurance roller 107.
The utility model is through increasing the hole that short rope safety device is installed on original bridge member 101; The structure of adjustment insurance bar; When making when steel rope loosening or fracture, the decline of the prevention machine that short rope safety block can be limited (this short rope safety device is inoperative when normal operation).
On original crossbeam two ends, respectively increase a short rope safety device, when the equipment normal operation, the steel rope tension, this weak point rope safety device does not play a role.And when steel rope is loosening, this weak point rope will further, and the snap effect through short rope safety block can stop the quick decline of four post lifting machines effectively.
