Device for the contraction of pipe sections of a pipeline *

The. The invention relates to a device for contraction of in a ditch or the like. inserted pipe sockets one Pipeline,

When laying pipes, especially those with large ones Diameters and high weight, such as those used for sewerage purposes, sewer pipes and the like, often very considerable forces have to be applied in order to the pipe sections at the joints and the socket ends against each other u4d so far into each other that a perfect Pipe connection is made. So far that has happened Pushing the pipe sections against each other and one inside the other by means of heavy

Reel, which was relatively cumbersome and time consuming. In addition, there is a risk of damage to the -Close the pipe.

The invention is primarily based on the object of eliminating these disadvantages and difficulties and of creating a device with which the or the like in open trenches. inserted pipe sections possibilities can be merged into the connecting state quickly and without significant difficulties ψ without this may result in damage to the pipes.

For this purpose, according to the invention at one end of the line there is provided a pressing station which supports itself against the pipe end located here and is displaceable in the longitudinal direction of the pipe. The press station here preferably has a slide or carriage receiving the press drive. The Preßantrieb expediently consists of a w or more of the printing cylinder

According to a further feature of the invention, the press drive is supported by an abutment, preferably consisting of a retaining beam or the like, at the adjacent pipe end, while the traction means engages a thrust bearing which is relatively movable in relation to this abutment in the longitudinal direction of the pipe and which preferably consists of a pressure beam or the like. consists. The pressure bearing or the pressure beam is here advantageously also designed as a slide or carriage and with the one that receives the press drive

Carriage or 'carriage connected via the press cylinder or cylinders. . * -

According to a further essential feature of the invention is the traction means can be extended according to the pipe length increasing during pipe laying, preferably one Rope drum is provided, which takes up the reserve rope and from which the rope according to the increasing pipe length is processed in sections. It is advisable to use an abutment, expediently a retaining beam or the like. to provide the pipe end opposite the press station and which is provided with a traction means guide or a capstan for the traction means guided through the pipe is. A design in which the rigid or equipped with a backstop is particularly useful. Spill is arranged on the pipe abutment or the retaining beam, while the rope drum receiving the reserve rope is located laterally next to the pipeline in the excavation or the open one Ditch is located. But there is also the possibility to structurally unite the cable drum with the abutment or the support beam. Instead of a spill could also a reel or the like provided with a drive and a rope drainage barrier. be used.

According to a further feature of the invention, the traction means of the capstan or of the reel is in the area of the opposite one Pipe end with a harness or the like. releasably coupled, which in turn is connected to the pressure bearing of the press station.

In the drawing is an embodiment of the invention shown. Show it:

In Figs. 1 and 2, a pipe section is shown, which is composed of the individual pipe sections la to If. The pipes here consist of bell-socket pipes known Execution as they are preferably used for sewers and the like. The cross-section of this made of concrete

'th tubes 1 can be seen from FIG. The connection of the Pipe sections are carried out according to Fig. 5 in such a way that the pipe sections are pushed into one another with their socket ends, the sealing of the socket connection by means of a RoIl-

. rubber seal 2od the like. he follows.

• On one side of the pipe string formed from the pipe sections la to If is in the one receiving the pipe a pressing station S arranged in an open trench. The press station has a carriage 9 on which two hydraulic press cylinder

the 3 are arranged, the piston rods 3 'on a Attack pressure bar 5, which also uses rollers is mobile in the trench. The back of the press cylinders 3 are supported on a support beam 4 which is attached to the carriage 9 the press station is stored. The press cylinder 3 is supplied with hydraulic fluid by means of "a pump 12, which can also be arranged on the carriage 9. To the Control of the pressurization of the press cylinder 3 is A control stand 6 is provided on the car.

With the pressure bar 5, a chain harness IO is connected, which is inserted into the pipe section la and here via a releasable coupling 13 with a. Rope 11 is coupled '. The rope 11 is wound onto a rope drum 8 on the side of the pipeline opposite the pressing station S. On this side of the pipe there is also a retaining bar 7 which is supported against the free end face of the pipe section If. As FIG. 3 shows, the retaining bar is designed in two parts, the two bar parts 7 '"and 7" forming an opening 14 for the passage of the rope in the middle area. In the opening 14 there is a rigid capstan 15 or one provided with a backstop, with the aid of which the reserve rope is wound onto the drum 8 or removed from it in the course of laying the pipeline.

Bs aei assumed that the pipe sections Id to If to a closed pipe string merged and properly

are sealed against each other. Then the open excavation of the pipe section la introduced. This pipe section la must then in the direction of arrow P against the pipe section Ib be pushed to make the socket connection, as shown in FIG. For this purpose, the Car 9 driven against the free end face of the pipe section la. And then the pull rope 11 is connected to the chain harness 10 of the pressure beam 5 at IJ. Afterward the press cylinders 3 on the piston side are acted upon by the hydraulic pressure medium of the pump 12 that the piston rods 3 "slide out. As the pressure beam 5 over the chain harness IQ and the pull rope 11 at the rear End of the pipe string, i.e. at the one against the pipe section If the retaining bar 7 is laid down, when the piston rod 3 'is pushed out, the carriage 9 with the retaining bar 4- is displaced in the arrow direction P, so that the pipe section la is taken along and brought into engagement with the adjacent pipe section Ib. Then the pressure cylinders are relieved of pressure on the piston side and on the The piston rod side is acted upon by the pressure medium of the pump 12, so that the piston rods slide in. During this process, the pressure bar 5 is moved back in the direction of arrow P, while at the same time the carriage; 9 in opposite Direction against the pressure beam 5 runs. After the hook coupling 13 has been released between the harness 10 and the pull rope 11, the entire pressing station S is about one The barrel is moved back the length of the shot, so that now another -.H ear-.

shot to be connected to the end pipe shank la can. To connect this pipe section to the pipe section la, the pull rope 11 must be the length of the pipe section from the Drum 8 can be unwound, which can be done with the aid of the capstan 7. The displacement of the new pipe section and its connection to the pipe shell la takes place in the above described way by the fact that the length of the pipe section extended pull rope 11 coupled at 13 with the chain harness 10 and then the press cylinder device in turn Hydraulic fluid is applied.
