Description

Self-propelled pipe molding machine {A driving pipe moulding machine}

The present invention relates to a pipe forming machine for forming a pipe widely used as a frame in a green house, etc., in a straight or curved shape depending on the application, and in detail, to a self-propelled pipe forming machine equipped with a power device for movement so that it can move by itself. will be.

In general, pipes used in green houses form a frame (frame) of a green house by bending a straight metal pipe into a dome shape and inserting both ends into the ground. Then, when constructing a green house, install a circular vertical pipe on the ground, and then fasten and fix a semicircular bent pipe on the top, or connect the pipe to the vertical pipe in the horizontal direction to form a vertical frame with a semicircular pipe. Connect it to make the frame of the plastic house. In addition, when the used house pipe is demolished, the bent pipe is straightened so as to form a straight line, and the pipe forming machine performs the above-described operation.

As a prior art related to the pipe forming machine, in Registration Patent No. 10-1461309, a pipe forming apparatus for installing a green house is installed on an agricultural work vehicle, so that a pipe for a plastic house skeleton can be formed at the work site, and 1 to 3 pipe inputs are formed to process the pipe forming device, and a safety fence and emergency stop button are installed at the entrance to the pipe supply device to facilitate the supply of pipes and protect workers, and operation of the pipe forming machine In addition to the driver's seat of the agricultural work vehicle, a separate hydraulic operating lever is installed at the lower part of the pipe input section of the pipe molding machine to control the hydraulic operation lever for convenient and safe green house with a safety fence attached to the improved agricultural work vehicle. Techniques for molding apparatus are provided.

According to another patent, Registration Patent No. 10-0665697, even if several types of pipes with different diameters are used depending on the size of the green house, a single bending molding machine can be used to unfold pipes of different diameters as well as to perform bending operations at the same time. There is provided a technology for a pipe bending molding machine for a greenhouse made to be able to.

Patent No. 10-0665697 has a straight forming part for forming a bent pipe into a straight shape, and a curved forming part for forming a straight pipe into a curved form.

Other patented technologies include a molding apparatus for a frame for installing a green house (Registration Patent No. 10-0832220), a frame molding machine for a green house (Registration Patent No. 10-1194845), and a frame for a plastic house manufactured through the same.

The pipe forming machine provided by the conventional techniques does not have a means (moving device) capable of moving by itself, and thus has a disadvantage in that it must be moved using a separate conveying device.

That is, if there is no device capable of transporting the pipe forming machine, it is impossible to move to the place where the pipe is located, and thus there is a disadvantage that the pipe must be moved toward the pipe forming machine.

As an additional explanation, there are cases where the pipe must be moved and the pipe forming machine must be moved depending on the conditions of the work site. However, if the pipe forming machine cannot move by itself, the pipe must be moved unconditionally, resulting in poor efficiency for work. There is this.

In addition, conventionally, when a pipe is formed to be bent, one or both ends of the pipe must be held by a worker other than the operator who operates the molding machine, so it is possible to work only with two or more people at all times, and a worker who holds one or both ends of the pipe In this case, when abnormal phenomena such as splashing or twisting occur during molding work, they are exposed to safety accidents.
