Description

  The present invention relates to a carriage for transporting a boring rod for cutting used for ground drilling work.

In the drilling operation with a boring machine, the excavation depth often reaches a considerable depth, and therefore it is generally necessary to perform the rod cut-over operation during the rod penetration operation.
This rod connection work can be carried out when the boring rod is small in diameter and light in weight and can be lifted and lifted manually, or even if the boring rod to be used is large in diameter and heavy in weight, the work site is wide and can be lifted by a crane etc. There is no special problem when you can, but if you cannot work with a lifting machine such as a crane attached to a boring machine in a narrow site or poor ground, you have to rely on human power to lift and work It was a big burden for the staff.

  Also, when placing a boring rod for cutover on the ground during work, a piece of wood was placed between one end of the rod and the ground, and the rod was laid on it, but Unfortunately, there was a risk that an operator trying to lift the rod could get his hand or feet caught in the rotating rod, which caused safety problems.

  The present invention solves the above-described problems and can provide a boring rod carrying cart for cut-over that can ensure workability and safety during transportation and temporary storage during work of the boring rod for cut-over. Is to provide.

In order to solve the above-mentioned problems, the present invention creates a cart dedicated to transport having a size matched to a large-diameter boring rod, and allows the storage cylinder that houses one end of the rod to be tilted on one side of the cart. It is provided.
In addition, a cart dedicated to transportation with dimensions matched to the large-diameter boring rod is created, and a loading platform on which the boring rod is placed is installed at a predetermined location on the platform frame of the bogie, and at one end of the frame. That is, a boring rod carrying cart that is provided with a storage cylinder that accommodates one end of the boring rod on the loading platform that can be tilted up and down is formed.
Furthermore, the rod loading table is provided with a holding member for preventing the rod from dropping.

  Since the boring rod carriage with a storage cylinder of the present invention is configured as described above, the rod can be moved quickly and efficiently during operation without a lifting machine such as a crane, Safety during temporary storage was also secured.

Embodiments of the present invention will be described based on examples with reference to the drawings.
FIG. 1 is a front view of a boring rod carrier cylinder with a boring rod storage cylinder of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a side view thereof.

In FIG. 1, reference numeral 1 denotes a cart, which is formed in a horizontal rectangular shape that matches the length of a boring rod 10 that uses the frame 2 of the cart 1. Loading platforms 3 on which boring rods 10 are placed are installed at a plurality of locations on the frame 2 of the carriage 1.
A rod storage cylinder 4 is attached by a hinge 5 to a loading table 3 installed on one end of the frame 2 so that the rod storage cylinder 4 can be tilted up and down. The length of the rod storage cylinder 4 is about 20 to 50 cm, more preferably about 25 cm, although it depends on the length of the rod 10.
If the length of the rod storage cylinder 4 is long, for example, 50 cm or more, the rod 10 is stored or taken out inefficiently, and if it is too short, it becomes unstable.

Further, hand grips 6 are attached to both ends in the longitudinal direction of the frame 2 so as to be rotatable and detachable at the hinge fulcrum 7, and the rod falls due to the tilt of the carriage near the loading platform 3 described above. A holding member 8 is provided for prevention.
In the figure, 9 is a wheel, 10 is a rod, 11 is a swivel, and 12 is a slurry hose (high pressure hose).

Since the present invention is as described above, at the time of work, the carriage 1 in which one end of the rod 10 is housed in the rod storage cylinder 4 is moved to a position near a boring machine not shown in the drilling site. In the drilling operation, when it is necessary to add the rod 10, the swivel 11 of the boring machine is removed, and the swivel 11 is attached to one of the rods 10 stored in the cart 1. When the swivel 11 has been installed, the cart 1 is directed toward the leader of the boring machine, and the rod is lifted up.
Next, when the winding is advanced and the rod storage cylinder 4 is raised near the vertical, the worker further winds up while supporting the storage cylinder side 4 of the rod, pulls out the rod 10 from the storage cylinder 4, and performs the rod joining operation.

If it is necessary to detach the rod 10, the storage cylinder 4 of the carriage 1 is vertically set up, and then the rod of the boring machine is disconnected, and the worker holds the rod 10 to which the swivel 11 is attached. Then, the rod 1 is guided to the position of the rod storage cylinder 4 of the carriage 1, and the rod 11 is accommodated in the storage cylinder 4 and placed on the carriage 1. Then, remove the swivel from the rod and finish cutting the rod.
At the time of movement, the worker moves to the next work position while pulling the handle 6. At that time, since the rod is placed on the rod loading table, a gap is formed between the frame 2 and the rod 10, so that the hand is caught by the rod 10 during lifting or grounding. It can be placed quietly.

  When the carriage is transported to a site where the scaffolding is poor with the carriage 1, even if the carriage tilts for some reason and the rod tries to rotate or drop, one end of the rod is inserted and supported by the rod storage cylinder 4. Moreover, since the pressing member 8 is provided on the underframe 2, the rod 10 can be prevented from rotating and falling, and safety can be ensured.

  Further, since the handle 6 for pushing attached to the carriage 1 is formed to be rotatable and removable, an operator can move the carriage 1 while pulling or pushing the handle 6 at the time of transportation, and the rod can be joined. Since the handle 6 can be detached from the carriage 1 during the separation work, the handle does not get in the way.

  The present invention does not require a suspension work vehicle such as a crane when working with a large-diameter weight rod, so that the rod can be stored and moved very efficiently and safely. It can be used even in difficult work sites.
