れる。 When the hydraulic jack in the contracted state is extended, the push ring that is engaged with the rear end of the transmission member moves forward, and the tube is propelled by the thrust of the push ring. After the hydraulic jack is fully extended, the hydraulic jack is retracted. Thereafter, the locking member that had been removed is attached to the transmission member, and the hydraulic jack is extended again. The pushing ring advances through the locking member and the transmission member, and the tube is further propelled forward. By extending the hydraulic jack twice and changing the locking position of the push ring with respect to the transmission member, a propulsion distance greater than the maximum stroke of the hydraulic jack can be obtained.

This makes it possible to obtain a tube propulsion device that is smaller in lateral length perpendicular to the direction of tube propulsion than the prior art devices. This allows the construction of shafts with smaller dimensions,
Alternatively, a larger working space can be obtained between the shaft wall and the tube propulsion device.

できる。 After propelling one tube, the hydraulic jack 32 is operated to contract in order to subsequently propel the other tube. At this time, since each pair of blocks 30 2 is engaged with the front end portion 42 of the transmission member 40, the press ring 16 2 is designated by the symbol 1.
6 Return to the position shown in 1 . The push ring 16 1 can be positioned near the plate 24 by the operator returning the push ring 16 1 further rearward after removing the locking member 54 . Due to the roller device 31 attached to the push ring 16, this return operation can be carried out easily and with less effort.

It is rotatably supported by both first beams 18 at both ends thereof. Further, each pair of front sprockets 70 is rotatably supported by both first beams 18 via a pair of rotating shafts 76 extending in the width direction. Both ends of each chain 72 are connected to a plate-shaped connecting member 78 fixed to the plate member 47.

するように制限される。 Accordingly, in response to the operation of the hydraulic jacks 32 on each side of the push ring 16, each transmission member 40 is moved to its respective first position.
When moving on the beam 18, the moving force is transmitted to the chain 72 through the connecting member 78, causing each pair of sprockets 68, 70 to rotate. At this time, the common rotating shaft 7 of both rear sprockets 68
4, the front sprocket rotates at the same speed. From this, even if there is a difference in speed between the hydraulic jacks 32 on both sides of the push ring 16, the speed adjusting means 32
6, the hydraulic jack is limited to operate at the same speed.
