Description

The present invention relates to a drilling boring rod transfer device used for adding a drilling boring rod when drilling a ground for injecting a chemical solution for ground improvement. The present invention relates to a boring rod transfer device for drilling that enables easy, quick and reliable addition of boring rods while ensuring the above.

As is well known, when constructing a dam or a huge structure, the ground is improved and strengthened by injecting a chemical solution into the ground. It is necessary to drill holes to form boring holes.

Explaining the method of drilling holes in the ground, FIG. 3 is a diagram showing a general self-propelled drilling machine, and 51 is a drilling machine in the figure. In this drilling machine 51, a slide base 52 is mounted on the upper part of a moving means 56 such as a caterpillar, and the slide base 52 is supported by a cylinder 53, and the angle can be freely changed by the action of the cylinder 53.

By the way, the boring rod used for drilling is generally about 1 to 2 meters, and the moving distance of the device body that gives an impact to the boring rod is regulated by the length of the slide base 52. In order to drill a hole in the ground to a predetermined depth with a rod, it is necessary to drill a hole while adding a boring rod.

Conventionally, the work of adding the boring rod has been mainly performed manually. That is, usually several people lift the boring rod by hand from the rod storage area and move it to the drilling machine, and then retract the device body 54 to install a new boring rod with the rod already installed. While arranging between the device main bodies 54, the tip end was connected to the rear end of the preceding bowling rod, and the rear end was attached to the device main body 54, whereby the bowling rod was replenished.

However, with this method, there is a possibility that the hand holding the boring rod may slip and the hand may be separated from the boring rod, which increases the burden on other workers and may cause an accident. In particular, the risk of an accident increases when the replenishment work overlaps and the worker's fatigue is high.

In this regard, conventionally, a crane has been used to carry the boring rod to the drilling machine and to add the boring rod. In this case, it is easy to carry the boring rod to the drilling machine, but after that, the drilling machine is used. When connecting a new boring rod to the rear end of the boring rod attached to, it is necessary to operate the crane, especially because the position and height of the boring rod must be adjusted, and detailed operations are required. It has been pointed out that this is not possible and the work becomes complicated.

It is also conceivable to manually replenish the boring rod after transporting the boring rod to the drilling machine with a crane, but in this case, the safety of the operator is ensured because the replenishment work is finally performed manually. It is difficult to secure it completely.

Therefore, the present invention makes it possible to easily, quickly and surely add a boring rod while ensuring the safety of an operator without performing complicated work when adding a drilling rod for drilling in the ground. An object of the present invention is to provide a transfer device for a boring rod for drilling.

It is possible to safely and quickly replenish the boring rod without causing an accident of the operator. Further, unlike the method in which the boring rod is carried to the drilling machine by a crane and replenished, it is not necessary to perform detailed operations on the crane, and the work is easy. On the other hand, since the balancer can easily finely adjust the position of the hook by hand, it is possible to easily, quickly and surely add the boring rod.

Further, in this embodiment, an electric balancer is used as the suspension device, but this electric balancer uses an air type balancer in order to reduce the weight of the suspended heavy object to zero by the motor. Unlike the case where there was, no plumbing work is required.

Also, the electric balancer does not have such a function because it is equipped with a load sensor and can quickly adjust the motor in response to changes in the weight of the suspended heavy object. Unlike the case of using an pneumatic balancer, even if the weight of a suspended heavy object changes, it is possible to quickly respond to the change in weight without performing any work, and it is possible to ensure safety. It is possible.

As described above, the transfer device of the present embodiment includes a transfer device main body for holding and moving the bowling rod and a suspension device provided in the transfer device main body, and is electrically operated as the suspension device. By using the balancer of the above, the boring rod for replenishment is suspended by the electric balancer and moved to the drilling machine, and the boring rod is moved up and down by the electric balancer and finely adjusted manually. Because it can be done, unlike the conventional method where all the movement and installation of the boring rod is done manually, the boring rod is not dropped, the operator's accident is not induced, and it is safe and quick. It is possible to add boring rods.

The drilling rod transfer device of the present invention can be generally applied when moving a heavy rod.
