Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe transporting apparatus for transporting a plurality of pipes continuously while rolling on a slanted skid. In order to index the pipes in order, the stopper is raised from below the slanted skid. The present invention relates to a pipe auxiliary transporting device capable of pushing and transporting a pipe that does not start rolling when the stopper is lowered to reroll the pipe after stopping the rolling of the pipe.

[0002]

2. Description of the Related Art In a pipe transporting apparatus for transporting a plurality of pipes continuously while rolling on a slanted skid, a stopper is lifted from below the slanted skid to roll the pipes in order to index the pipes in order. When stopped, the pipe located on the upper end side of the sloped skid from the stopper stops at each stop position while causing a slip between the sloped skid and the pipe. Then, since such a slip phenomenon occurs, the upper surface of the inclined skid is locally scraped off by the pipe and worn. When such local wear of the inclined skid progresses, there is a problem that the pipe is fitted into such a worn portion of the inclined skid, does not roll, and cannot be conveyed.

Further, when a plurality of pipes are continuously conveyed while rolling on an inclined skid, even if the pipes are largely bent in the longitudinal direction, the pipes do not roll and cannot be conveyed. There's a problem.

As a solution for the case where the pipe cannot be conveyed as described above, the conventional method is to restart the conveyance using a pipe auxiliary conveying device as shown in the side view of FIG. ing. The pipe auxiliary transport device will be described below with reference to FIG. That is, this pipe auxiliary transporting device includes a support member 23 fixed to the support column 22 a of the inclined skid 21 and a pin 2 provided on the support member 23.
4, a movable skid 25 having one end 25a rotatably connected thereto, a connecting member 26 fixed to the other end 25b of the movable skid 25, and a pin 2 provided on the connecting member 26.
A cylinder rod 28 is rotatably connected via a hydraulic or pneumatic cylinder 29. And the hydraulic or pneumatic cylinder 29 is
Support member 31 fixed on the floor or fixed member 30
Is rotatably connected via a pin 32 provided on the support member 31.

When a pipe that cannot be conveyed is conveyed again by using the above-mentioned conventional pipe auxiliary conveying device,
Hydraulic pressure or pneumatic pressure is supplied to the hydraulic or pneumatic cylinder 29 to push up the cylinder rod 28 and push up the end 25b of the movable skid 25. When the end 25b of the movable skid 25 is pushed up, the movable skid 25 rotates upward about the pin 24. Therefore, the pipe 33 a stopped on the inclined skid 21 is lifted upward by the movable skid 25. Then, the pipe 33b on the movable skid 25 starts rolling along the inclination of the movable skid 25 and is conveyed to the lower end side of the inclined skid 21.

[0006]

However, when a pipe that cannot be conveyed is conveyed again by using the above-mentioned conventional pipe auxiliary conveying device, the hydraulic pressure or pneumatic pressure supplied to the hydraulic or pneumatic cylinder is the whole of the pipe. Since a pressure sufficient to support the weight is required, there is a problem that the power cost becomes high.

Further, in order to solve such a problem, as shown in FIG. 3, a support 22b of the inclined skid 21 is provided.
The movable skid 2 is rotatably connected to the support member 34 fixed to the support member 34 via a pin 35 provided on the support member 34.
The connecting member 26 fixed to the other end 25b of the pin 5 is the pin 36
It is also conceivable to reduce the hydraulic or pneumatic pressure supplied to the hydraulic or pneumatic cylinder by using a cam 38 rotatably connected to the cylinder rod 28 via a pin 37. However, there is a problem in that the equipment cost increases and it is difficult to secure an installation space.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a pipe auxiliary transporting device which can reduce the power cost without complicating the structure. I am trying.

DISCLOSURE OF THE INVENTION A pipe auxiliary carrier according to the present invention is a pipe carrier having a plurality of inclined skids arranged in parallel, below the inclined skid and in parallel and horizontally to the inclined skid. A rail provided, a pipe extrusion head whose upper surface is moved upward from below the inclined skid by advancing on the rail toward the lower end side of the inclined skid, and this pipe extrusion head is provided along the rail. It is composed of a drive device for moving the vehicle forward and backward.

[0010]

When the pipe on the inclined skid that cannot be conveyed is conveyed again by using the pipe auxiliary conveying device according to the present invention, the pipe pushing head is moved forward by the driving device. The tilted skid descends toward the front, while the rail is installed horizontally, so the pipe extrusion head moves forward so that its upper surface is above the upper surface of the tilted skid. The pipe extruding head pushes forward the pipe stopped above, and the conveyance is restarted. When the pipe auxiliary transport device is not used, the pipe extrusion head is retracted to a position where the upper surface of the pipe extrusion head is below the inclined skid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pipe auxiliary carrying device according to an embodiment of the present invention will be described with reference to the side view of FIG. This pipe auxiliary transporting device is provided with a rail 1 horizontally provided with both ends fixed to columns 22a and 22b of an inclined skid 21, a pipe extrusion head 2 arranged along the rail 1 so as to be able to move forward and backward, and this pipe. It comprises a hydraulic or pneumatic cylinder 3 for moving the extrusion head 2 forward and backward. To further explain the pipe auxiliary transport device in detail, the hydraulic or pneumatic cylinder 3 includes a support member 4 and a pin 5 fixed to the rail 2.
Is rotatably connected via. The tip of the cylinder rod 6 is rotatably connected to a connecting member 7 fixed to the pipe extrusion head 2 via a pin 8. Further, the tip portion of the pipe extrusion head 2 has an inclined portion 2a.
Is provided.

When the pipe 33 stopped on the inclined skid 21 is conveyed by the above-mentioned pipe auxiliary conveying device, hydraulic pressure or pneumatic pressure is supplied to the hydraulic or pneumatic cylinder 3 to advance the pipe extrusion head 2. The installation position of the pipe extrusion head 2 is taken into consideration so that the upper surface of the pipe extrusion head 2 is located below the upper surface of the inclined skid 21 when it is retracted, and is located above the upper surface of the inclined skid 21 when it is advanced to some extent. . When the upper surface of the pipe extruding head 2 goes above the upper surface of the inclined skid 21, the inclined portion 2a of the pipe extruding head 2 contacts the pipe 33 stopped on the inclined skid 21, and the pipe extruding head 2 moves. When the pipe 33 is further advanced, the pipe 33 starts rolling along the inclined portion 2a of the pipe extrusion head 2 and the conveyance is restarted.

That is, the pipe 33 has the inclined skid 21.
When the pipe 33 is stopped in the range indicated by L, the pipe 33 can resume the conveyance by this pipe auxiliary conveyance device. In addition, by arranging a plurality of the pipe auxiliary transporting devices by shifting the position in the longitudinal direction of the inclined skid, or by making the rail 2 movable in the vertical direction,
Transport can be resumed wherever the pipe stops on the tilt skid.

When a pipe stopped on an inclined skid is conveyed by using the above-described pipe auxiliary conveying device of the present invention, the power required for conveying the pipe is generated by the pipe extrusion head 2. Since the power required to push up the pipe along the inclined portion 2a is sufficient, the power cost can be significantly reduced as compared with the conventional pipe auxiliary transfer device. Further, since no complicated mechanism is required, the facility cost is low and the space can be easily set. Furthermore, since the connecting structure between the constituent members is a rotatable structure, undue stress does not act between the members and maintenance is easy.

[0015]

According to the present invention, the power required for the pipe auxiliary conveying device can be reduced and the maintenance can be facilitated.
