Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, described guide rail is arranged the advance seat that can move back and forth along this guide rail, described propelling drive installation is on this advance seat.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, described advance seat comprises the fitting seat arranged in diagonal form, these two fitting seats is fixed described propelling respectively and drives.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, the described front end driven that advances arranges oil cylinder groove, described in promote mainly plate and be fixed in oil cylinder groove by voussoir.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, diagonally arranged in form two decks in described support body, the front end that described propelling drives is fixed on these two decks.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, it is added that described originating station comprises originating station, the added left and right sides of this originating station comprises originating station pressing plate, originating station side plate and originating station backing plate, two tugboat framves are set on originating station is added, this tugboat frame arranges rotating guide wheel, and these two tugboat framves are obliquely installed towards the axle center of apical ring.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, described originating station backing plate arranges the first wearing plate near described guide rail contacting surface place.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, it is added that described advance seat comprises advance seat, the added both sides of this advance seat arrange advance seat pressing plate, advance seat side plate and advance seat backing plate, and this advance seat backing plate arranges the second wearing plate near an end face of described guide rail.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, described propelling drives as propelling cylinder.
Preferably, in the advancing means of push-bench section of jurisdiction described in the utility model, described propelling driving is weldingly fixed on advance seat.
The beneficial effects of the utility model are:
Because the technical solution of the utility model adopts guide rail to guide the movement of originating station and advance seat, and the one end being fixed on the promotion oil cylinder on advance seat is fixed in support body, this technology can ensure to move when pipe laying not produce deviation, is conducive to improving pipe laying quality; Moreover apical ring is promoted mainly on plate by dismountable being arranged on, can according to section of jurisdiction greatly under can change, to realize reducing.

Embodiment
Be described further below with reference to accompanying drawing 1 to accompanying drawing 3 pairs of the utility model, but protection domain of the present utility model should do not limited with this.
Technological scheme novel with understanding the utility model for convenience of description, the noun of locality below used (as: front, rear, left and right etc.) orientation all represented by accompanying drawing is as the criterion.
Contrast accompanying drawing 1 to accompanying drawing 3:
Push-bench section of jurisdiction advancing means, comprises bearing 1, described bearing 1 have support body 11 with one along direction of propulsion arrange and the support saddle frame 12 vertical with this support body 11; Described support saddle frame 12 arranges guide rail 13 along direction of propulsion, and along at least one originating station 2 of setting gradually of can reciprocatingly moving of direction of propulsion with advance driving 3 on this guide rail 13, and one end of described propelling driving 3 is fixed in support body 11; Arrange one in described propelling driving 3 along the front end place of direction of propulsion and promote mainly plate 4, this is promoted mainly and dismountablely on plate 4 fixes an apical ring 5.
Concrete, described guide rail 13 arranges advance seat 6, this advance seat 6 is by advance seat pressing plate 61, advance seat side plate 62 and advance seat backing plate 63 form, and in the left side of advance seat pressing plate 61, circular arc bearing 7 is installed, on on the right side of circular arc bearing 7 and advance seat 6 legal person, fitting seat 71 is set, fitting seat 71 is fixed described propelling driving 3, also arrange on the right side of advance seat 6 and advance driving 3, preferably, this propelling drives 3 to be propelling cylinder, drive the right side of 3 that oil cylinder groove 31 is set in this propelling, on oil cylinder groove 31, card is established and is promoted mainly plate 4, in order to better fix, this is promoted mainly plate 4 and is fixed on oil cylinder groove 31 by voussoir 8.Support body 11 is arranged two with advance deck 9 corresponding to driving 3, described propelling drives the right-hand member limit of 3 to be fixed on described deck 9.Promoting mainly the central position of plate 4 by the dismountable installation apical ring 5 of screw, selecting of this apical ring 5 is determined according to the size of section of jurisdiction, can select arbitrarily and change.Originating station added 21 is comprised at the originating station 2 in the left side of advance seat 6, the left and right of this originating station added 21 arranges originating station pressing plate 22, originating station side plate 23 and originating station backing plate 24, and described originating station pressing plate 22 and described originating station side plate 23 are bolted on originating station added 21; Originating station pressing plate 22 arranges two tugboat framves 10, this tugboat frame 10 arranges rotating guide wheel 101, and these two tugboat framves 10 are obliquely installed towards the axle center of apical ring 2.Advance seat 6 also arranges two tugboat framves with guide wheel corresponding with the tugboat frame 10 be arranged on originating station 2; This advance seat 6 comprises advance seat added 61, and the both sides of this advance seat added 61 arrange advance seat pressing plate 62, advance seat side plate 63 and advance seat backing plate 64, and the lower end surface of this advance seat backing plate 64 arranges the second wearing plate 02.In the utility model, can section of jurisdiction be placed by these two groups of tugboat framves 10, prevent the skew of section of jurisdiction.Meanwhile, in order to ensure that originating station 2 and advance seat 6 reduce in reciprocal movement as far as possible, guide rail 13 is worn and torn, the first wearing layer 01 and the second wearing layer 02 is set respectively in the place that originating station 2 and advance seat 6 contact with guide rail 13.
When specific works, section of jurisdiction is positioned on the tugboat frame 10 on originating station 2 and advance seat 6, and the right-hand member of section of jurisdiction by clamp in apical ring 5, can ensure that section of jurisdiction does not produce cheaply in moving process like this, improve the quality of pipe laying, reduce the joint gap between section of jurisdiction.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned mode of execution and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
