Description

[Detailed description of the device] (Industrial application field)   The present invention relates to a sandwiching carrier for construction (hereinafter abbreviated as a carrier), and particularly to a road carrier. It is suitable for use when carrying out construction work of uncreto products. (Conventional technology)   Conventionally, as a carrier of this type, a pair of arms as shown in FIG. And use it in combination with the required one of the multiple engagement holes that are continuous in the arm longitudinal direction. Things are known.   The method of use is extremely simple: place the clamp pieces (2) on both sides of the load (8) and continue. Normally, two people lift the handle (1) to reduce the distance L1 of the gripping piece. , It is possible to pick up and lift a transported object. (Issues to be solved by the device)   In the conventional technology, due to the variation in the length of the transported object, the clamping is insufficient and easy. It had a problem that it would come off.   In addition, for transportation and attachment / detachment work, one person can carry the carrier to the wearing work position, and then two people can grip it. The work is repeated, the transported article is removed, and the work of returning to the landing position by one person is repeated. However, since the opening angle of the supported arm is not limited, a sandwiching piece is required during attachment / detachment work. There was a problem in that the movement was more than necessary and the work was troublesome.   Also, due to the physique of the worker, especially the height difference and the difference in working posture, a straight handle The work environment tends to be biased, and the work environment changes from a high position with a height difference to a low position. When you need to carry a large difference between lifting and lowering, such as when Have   The present invention has been made in view of such problems of the conventional technology. For the purpose of, it is possible to securely pinch the transported items with a simple operation. At the same time, we provide a construction carrier that saves labor during attachment and detachment work and reduces the work load during transportation. Is what you are trying to do. (Means for solving the problem)   In order to achieve the above object, the carrier according to the present invention has a handle ( 1), a pair of arms (3) provided with a sandwiching piece (2) facing downwards at the other end is a pair of cross bearings It is a carrying tool and is opposed to each other via a guide (4) for moving the holding piece in the longitudinal direction of the arm. The screw feeding device for positioning the sandwiching piece so that the distance L1 of the sandwiching piece can be adjusted. It is characterized in that the device (5) is provided. And the clamping piece is useless when attaching and detaching In order to prevent movement, separate the transported object with the maximum opening angle θ1 of the supported arm. An arm opening angle restraint section (6) for detaching and returning to the wearing work position as it is. It is preferable to provide a moving handle (7).   Further, the shape of the handle (1) is generated due to the difference in height and the working posture of the worker. The grip position of the handle is adjusted to make it easier to correct the work load and transport the product with different heights. It is preferable that the upper and lower portions have a substantially annular shape so that the operator can select them at appropriate times. (Action)   The carrier is positioned so that both sides of the carrier are held by the clamp pieces on the carrier. The distance between the sandwiching pieces is adjusted by a screw feeding device before the work. And the hand By pulling up the lever, the gripping piece will firmly pinch the transported object, The load can be lifted. Next, by pulling up the moving handle, the arm The force that opens to the outside of the sandwiching piece that is connected to the When the handle is pulled up, the arm widens the opening angle and comes into contact with the arm opening angle restraining part and stops. Can be (Example)   Hereinafter, the present invention will be described based on embodiments. FIG. 2 shows an example in which a screw feeding device for positioning the holding piece is provided. this The feeder is a male screw (9) with one end fixed to a moving handle or arm in a cantilevered fashion. , The male screw is passed through the cylindrical portion (10) of the guide, and both sides in the longitudinal direction are screwed by the female screw (11). It locks.   The moving handle (7) has one of the handle (1), the arm (3), and the gripping piece (2). ) Provided on the holding piece side of the arm with respect to the center of gravity of the assembly of the screw feeding device (5) There is. As a result, the gripping piece can always maintain the maximum length when holding the moving handle. it can. In addition, the moving handle is provided on the side of the gripping part of the arm with respect to the shaft center. When the handle is pulled up, the force to open the arm earlier than the other arm is acting. . In addition, as shown in Fig. 5, the moving handle has a moving handle angle to prevent it from swinging in the A direction. The balance is corrected by providing θ2.   The arm opening angle restraining portion (6) is located on the upper portion of the sandwiching piece, and has a substantially annular handle (1 ), When the handle movement distance L2 is L2 = 0, The opening angle θ1 of the arm is suppressed. Also, the arm opening angle restraining part is It can also be provided in a protruding shape on the lower part of the dollar or the upper part of the sandwiching piece.   The handle is shaped like a ring with a straight line partially arranged to make it easier for the operator to grip. The cross section is tubular in terms of weight reduction, workability, and cost. (The invention's effect)   Since the present invention is configured as described above, it has the following effects.   In the carrier according to claim 1, the distance between the sandwiching pieces facing each other is adjusted by a screw feeding device. Since it can be adjusted, the clamping does not depend on the variation in the length of the transported object. , It will not come off easily and will be reliable.   In the carrier according to claim 2, the moving handle is provided on the side of the sandwiching piece with respect to the center of gravity. Therefore, if you pull up the moving handle, the handle side will drop due to its own weight and the arm will open. The sandwiching piece can keep the maximum length by contacting the angle restraining portion. This makes it possible to carry The pinching piece does not cause unnecessary movement during the attachment / detachment work.   In the carrier according to claim 3, the operator has a substantially circular handle shape. Can select the grip position of the handle at any time. As a result, the height difference of the worker and the work The work load caused by the difference in posture is corrected. Also, regarding transportation with height differences Can be done easily.
