Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pipe transfer device used in a pipe propulsion work.

[Conventional technology]

If there is road surface lining, etc., in the tubular body propulsion work, it will be an obstacle, and the hanging position of the tubular body must be laterally displaced from the tubular body propulsion center line. It is not possible to lower the pipe directly, and it is necessary to temporarily suspend the pipe in the shaft and then move it laterally to the pipe propulsion unit.

Then, conventionally, as shown in FIG. 5, the suspended tubular body 51 is suspended from a beam 53 erected in a vertical shaft 52, and the traveling body 54 laterally moves the tubular body 51 to the tubular body propelling section 55. Attach the winch hoist 62 to the side wall of the vertical shaft 61 as shown in the figure,
Hook the wire 64 on the suspended tube 63, and
The winch hoist 62 was used to wind up 64 to move the tubular body 63 to the tubular body propulsion section 65.

However, with such a conventional technique, it is necessary to move the pipe body while it is in an unstable suspended state, which deteriorates the work efficiency and prevents the pipe body from swaying under the pipe body. There is a problem that a personal injury is likely to occur because it requires a worker. Furthermore, the work of setting the pipes in the pipe propulsion unit must also be performed on the pipes that are suspended in the air, which requires work in high places in an unstable state, further increasing the risk. During the setting, there was a problem that the pipe body collided with surrounding structures and the like to damage the pipe body and the like.

The auxiliary roller 24 is attached, and the pivotal support portion 42 is attached to the upper surface of the frame body 21 near the hanging portion D. The motor 23 attached to the frame body 21 is used as a drive source for traveling. The size of the frame body 21 is about 2 m in each length and breadth, but the design can be changed appropriately according to the size of the pipe body a. The control of the motor 23 and the bed elevating means 4 is performed by an operation unit (not shown) provided in the frame body 21, but it may be performed by remote operation.

The tubular body mounting bed 3 is formed by combining steel materials in a rectangular shape, and the dimensions of the tubular body mounting bed 3 are configured to be substantially the same as the frame body 21. A bent portion 31 that is bent obliquely upward is provided at an end portion of the tubular body mounting bed 3 near the hanging portion D.
Are formed. The tube mounting bed 3 is placed on the frame 21 in an overlapping manner, and the bent portion 31 is pivotally attached to the pivotally supporting portion 42 of the transfer carriage 2 so that the tube mounting bed 3 is rotatable. ing.

The bed height adjusting means 4 has a structure for moving the pipe body mounting bed 3 up and down by the hydraulic jacks 43, and the hydraulic jacks 43 are located on both sides of the bed 3 in the traveling direction of the transfer carriage 2. , The tip of the piston rod 44 of the hydraulic jack 43 is pivotally attached to the end of the pipe mounting bed 3 near the pipe propelling section B, and the base end of the jack main body 45 of the hydraulic jack 43 is provided on both sides of the frame 21. It is configured to be pivotally attached to each central part.

A receiving seat 5a is removably attached to the upper surface of the side of the tube mounting bed 3 near the tube propelling section B, and the tube positioning means 5 is provided on both sides of the receiving seat 5a and the tube mounting bed 3. It is composed of a frame member 3a and a recessed portion 32 including a bent portion 31. The recessed portion 32 is formed in the width direction of the tube mounting bed 3 (direction orthogonal to the traveling direction of the transfer carriage 2).

Further, rollers 6a for moving the tube a in the tube axis direction are attached to the center of both side frame members 3a of the tube mounting bed 3 and the tips of the bent portions 31 and the tube mounting surface of the seat 5a. Has been done.

In FIG. 1 and FIG. 2, B is a tubular body propulsion unit, which is a propulsion jack B2 interposed between the pressure bearing wall B1 and the tubular body a, and a propulsion jack laid in the propulsive direction of the tubular body a. It consists of a push frame B4 that runs on the rail B3. Rail B3 is horizontal rail 1
The transverse rail 1 is cut at the rail intersection to form a gap 1a.

At this time, since the auxiliary rollers 24 are attached to the transfer carriage 2, even if the transfer carriage 2 approaches the rail intersection, the wheels 22 of the transfer carriage 2 fall into the cutting portion 1a of the horizontal rail 1 and derail. Is not present (see FIG. 3). B5 is a mount for the propelling rail B3.

Next, a tube propulsion process using the tube moving device will be described.

First, as shown in FIG. 1, a pipe a hung by a crane or the like is hung from the ground into a shaft A.

Next, as shown in FIG. 3 (a), after the pipe a is placed on the pipe placement bed 3 of the transfer carriage 2 located at the hanging portion D and the pipe positioning means 5 is used for positioning. By driving the motor 23, the transfer carriage 2 on the horizontal rail 1 is moved to move the pipe body a to the pipe body propulsion unit B and introduce it into the pipe body propulsion unit B.

At this time, the pushing frame B4 of the tubular body propelling section B is moved to the pressure bearing wall B1 side in advance and placed in the state before the tubular body propelling, so that the tubular body a by the transfer carriage 2 can be introduced into the tubular body propelling section B. Keep the potential ready.

Next, in the tubular body propulsion unit B in which the tubular body a is introduced,
As shown in FIG. 3B, the height adjusting means 4 causes the pipe a to match the set level of the pipe propelling unit B, and then the pipe a is set in the pipe propelling unit B.

Next, after lowering the tube mounting bed 3, the motor 23
Is reversed and the transfer carriage 2 is moved in the direction of the hanging portion D.

When the pipe a is caught on the receiving seat 5a of the transferring carriage 2 when the transferring carriage 2 is moved toward the hanging portion D, the receiving seat 5a is once removed from the bed 3.

Next, as shown in FIG. 2, the tubular body a propelling section B propels the tubular body a.

Then, by repeating the above work, the tubular body a is sequentially promoted.

[Effect of device]

As is clear from the above description, according to the pipe moving device of the pipe propulsion device of the present invention, the suspended pipe can be placed on the bed of the transfer carriage and laterally moved to the pipe propulsion unit. Moreover, since the tubular body can be positioned in the recess of the tubular body mounting bed and laterally transferred in a stable state, the tubular body does not inadvertently shake during lateral movement of the tubular body. No need for an operator to enter the bottom of the pipe to prevent the pipe from shaking, ensuring safety and improving work efficiency.

In addition, since the tube can be set in the propulsion unit in a stable state, the setting can be performed smoothly and the setting work at a high place is unnecessary, and the work can be performed more safely. Therefore, the tube body will not collide with surrounding structures and the like during the setting, thereby damaging the tube body and the like.

Further, the transfer carriage can be retracted from the tubular body propulsion unit, and the tubular body propulsion work can be smoothly performed.

In particular, by lowering the tube mounting bed to such an extent that the tube mounting bed does not come into contact with the lower portion of the tube, the transfer carriage can be retracted. In order to secure it, it is not necessary to raise the tube mount bed by a height equivalent to the protruding dimension of the seat before setting the tube in the tube propulsion unit. The difference from the bottom level can be reduced, and there is no need to dig the shaft more than necessary.
