The specific embodiment
Referring now to description of drawings a kind of preferred implementation of the present invention.
Fig. 1 and Fig. 2 are the perspective views according to the saw-teeth type hydraulic jack 1000 of one embodiment of the present invention.Fig. 3 is the cross sectional view of saw-teeth type hydraulic jack 1000, has shown the internal structure of saw-teeth type hydraulic jack 1000, does not wherein show support 10.
Referring to figs. 1 through Fig. 3, saw-teeth type hydraulic jack 1000 has cylinder body 100, and hydraulic pressure chamber 300 is formed in the cylinder body 100.
Guiding valve 500 is installed in the hydraulic pressure chamber 300 that is arranged in cylinder body 100.As shown in the figure, be formed with passage 180 on the sidepiece of cylinder body 100, on this passage 180 the hydraulic pressure mouth of pipe 80 be installed.Passage 180 and external communications.
Therefore, can provide hydraulic pressure to hydraulic pressure chamber 300 from the hydraulic pump (not shown).For example, if erection joint (coupler) and this joint is connected with the mouth of pipe 80 on the end of the flexible pipe of described hydraulic pump then can be provided to hydraulic pressure hydraulic pressure chamber 300.Hydraulic pressure is provided, guiding valve 500 is moved to left.
In the present embodiment, cylinder body 100 is divided into part 110 and 130 two parts, and these two parts interconnect.For example, described two parts can interconnect by the bolt (not shown).
Be provided with ring 470 around the spool of guiding valve 500 along the periphery of the spool of guiding valve 500.
Open in the left side of cylinder body 100, and the bar 540 of guiding valve 500 is outwards outstanding, and moveable support member 40 is connected with bar 540.In the present embodiment, the handle 48 of moveable support member 40 is inserted in the bar 540, bolt 91 and 93 bolt connecting rods 540 and moveable support member 40.
In guiding valve 500, be formed with cavity part 350 at the sidepiece of passage 180.Be provided with first spring support member 410 on the right side of cavity part 350.This first spring support member 410 combines with the inboard of cylinder body 100 by bolt 430.Be provided with second spring support member 420 in the left side of cavity part 350.This second spring support member 420 combines with the bar 540 of guiding valve 500 by bolt 450.Spring 88 is installed as and passes first spring support member 410 and second spring support member 420.
Therefore, when guiding valve 500 moved to the left side, spring 88 extended to the left side and gathers restoring force.
When described hydraulic pump provides hydraulic pressure by the mouth of pipe 80, this hydraulic pressure enters hydraulic pressure chamber 300 by passage 180 and makes guiding valve 500 move to the left side, thereby makes moveable support member 40 move to the left side.
On the contrary, when hydraulic pressure left hydraulic pressure chamber 300, moveable support member 40 moved to the right side and gets back to initial position by the restoring force of spring 88.
According to the present invention, outside projected direction is formed with a plurality of teeth 41 in the upper edge, end of moveable support member 40.
Tooth 41 has zigzag fashion, and the line that connects the end of tooth 41 forms circular arc.
That is to say that with reference to Fig. 3, the line of the end of a plurality of teeth 41 of connection moveable support member 40 is the same circle extension of R1 and forms circular arc S1 along radius.
In cylinder body 100, support component 60 is outstanding at the opposite side of moveable support member 40 relatively.Support component 60 can be fixed to cylinder body 100 relatively.In the present embodiment, support component 60 is inserted in the sidepiece of cylinder body 100 relatively, and bolt 92 is connected cylinder body 100 and relative support component 60 with 94 bolts.
The outside projected direction in upper edge, end at relative support component 60 is formed with a plurality of teeth 61.Tooth 61 has zigzag fashion, and the line that connects the end of a plurality of teeth 61 forms circular arc.
With reference to Fig. 3, the line of end that connects a plurality of teeth 61 of relative support component 60 is that the same circle of R2 extends and form circular arc S2 along radius.
The circular arc S1 that is formed by a plurality of teeth 41 of moveable support member 40 is symmetrical with the circular arc S2 that a plurality of teeth 61 by relative support component 60 form.
The bottom of cylinder body 100 is provided with support 10, and this support 10 is used to support cylinder body 100, and cylinder body 100 is tilted with respect to base portion.
With reference to Fig. 4 and Fig. 5, the work according to the saw-teeth type hydraulic jack 1000 of one embodiment of the present invention is described.
At first, upright steel plate 900 is arranged between top T and the base portion B, and when cylinder body 100 tilts, saw-teeth type hydraulic jack 1000 is arranged between steel plate 900 and the base portion B.Connect the hydraulic pump (not shown) by the mouth of pipe 80.The joint that will be positioned on the end of flexible pipe of this hydraulic pump inserts the mouth of pipe 80 and this joint is connected with the mouth of pipe 80.
In this case, weld at the A place, position on top T.
In this case, the heat that steel plate 900 is attempted to produce by welding is out of shape, to rotate along direction D1 around position A.Hydraulic pressure is provided to saw-teeth type hydraulic jack 1000, and moveable support member 40 moves towards base portion B, therefore, moves (referring to Fig. 4) relative to support component 60 towards steel plate 900.
The line of the end of a plurality of teeth of connection moveable support member 40 and the line of the end of a plurality of teeth that are connected relative support component 60 form symmetrical circular arc S1 and circular arc S2.
A plurality of teeth 41 of moveable support member 40 one after the other are driven in the base portion B along circular arc S1, and correspondingly, the tooth 61 of support component 60 one after the other promotes steel plate 900 (referring to Fig. 5) along circular arc S2 relatively.
The track that forms when the tooth 61 of support component 60 promotes steel plate 900 is relatively followed the direction D2 opposite with direction D1, and corresponding with described distortion, perhaps is similar to described distortion at least, thereby makes steel plate 900 be returned to described initial position.
Steel plate 900 keeps described initial position in this way, and can weld at the B place, position on the described base portion.
When saw-teeth type hydraulic jack 1000 supporting steel plates 900 (this steel plate 900 is a welding work pieces), the tooth 41 of moveable support member 40 is inserted among the base portion B.But the scar that produces during with the use thread is compared, and the scar that produces on base portion B is very little in this case, and this scar can coated coating thereon be covered.
Fig. 6 and Fig. 7 have shown the saw-teeth type hydraulic jack 1000 that hand pump 5000 is installed.
In this case, when the handle 944 of hand pump 5000 moves up and down, suction piston 908 moves up and down repeatedly, and the check-valves 910 and 930 that is positioned on the both sides of bottom of this suction piston 908 alternatively opens and closes, so that the hydraulic pressure in the oil groove 980 is pumped, thereby provide hydraulic pressure by the hydraulic pressure chamber 300 of passage 180 in cylinder body 100.
As mentioned above, the invention provides a kind of saw-teeth type hydraulic jack, this saw-teeth type hydraulic jack can be corresponding to distortion and supporting workpiece and can prevent to produce big scar on base portion.
Saw-teeth type hydraulic jack according to the present invention is mainly used in welding, is not limited only to this but be construed as.
Now, can be understood as and realized purpose of the present invention.With reference to the specific embodiment the present invention has been described, but the present invention is not limited only to this.Have only appended claim can limit scope of the present invention.
