Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transporting device for transporting personnel, which has been developed from a single rail transporter for agriculture used to transport fruits, fertilizers, etc., installed on a steep slope such as an orchard, and particularly the configuration of the rails. It is about.

[0002]

[Prior art and problems]

 As shown in Fig. 3, a single rail carrier conventionally used for transporting fruits is constructed by laying a single square pipe rail at a height of about 30 cm above the ground with columns arranged at regular intervals. The welded rack meshes with the pinion of the drive vehicle, and the pinion rotates to move forward and backward. The meshing of the rack and pinion is suitable for steep ascending and descending at a slow speed, and it has been used for a long time, but the maximum payload for use in orchards is around 200 kg to 300 kg. It was

Although this was an ability suitable for the purpose of carrying fruits and the like, it left a problem when considering the transportation of 4 to 5 personnel.

In the recent construction of power transmission lines, there is no choice but to select a steep mountainous area due to land acquisition problems, environmental problems, etc. More than that, the need to climb mountain roads has arisen. It takes three to four years to complete the construction of the power transmission line from the survey stage to completion, but during that time, commuting more than two hours each day is not only a waste of time, but also physical fatigue, and Furthermore, it was not a particularly favorable situation when performing high-altitude work on a tower.

Therefore, a single-rail transportation device suitable for steep mountain transportation was planned, but its weight capacity is about 200 kg to 300 kg as mentioned above, including a driving vehicle and a trolley for personnel. And this project, which exceeds 1t, could not be done without improvement of the current product.

Although the capacity of a driving vehicle can be solved to some extent by increasing the size of the engine, the conventional railroad rail has been a concern with a single square pipe rail. Rails are laid at a height of about 30 cm above the ground, and the degree of fixation of rails differs depending on the condition of the surface layer, and considering the changes in natural conditions after installation, rail laying At the beginning and after a lapse of time, the degree of fixation of the columns into the surface layer has also changed due to the steep slope, and it is safer for personnel to support the rails only with columns arranged at intervals of about 1 m. It is considered that it is not suitable for transportation. Another problem in planning personnel transportation is the instability of the single rail itself, which is easy to install and the instability of the single rail is taken into consideration. It was considered necessary to find a compromise.

Therefore, as shown in FIG. 2, a rail structure of a single rail carrier having a main rail 4 and an auxiliary rail 7 was devised, and the problem of strength against heavy objects for transporting personnel was solved. However, a heavy-duty drive vehicle or a trolley for people will pass through it many times, and if the rack 3 is deformed by the shock of a sudden stop of the drive vehicle, it will be difficult to replace the main rail. It was

Because even if the bolts and nuts at the connecting portion of the main rail 4 are removed, it cannot be removed because the connecting metal fitting is inside the main rail 4, so either remove the main rail 4 from the support pillar or I used to lift it and change the length of the rail to forcefully remove it.

When the above-mentioned main rail 4 is removed from the main pillar 1, when a new rail 4 is inserted, the hole position of the rail does not match, and it is difficult to fit the support bracket 11 onto the main pillar 1. If it is difficult or if the main pillar is lifted together, the main pillar 1 will fit in the same hole even if it seems to fit well with the rail 4, so the installation fixing degree will be loose, and the main pillar 1 will be wobbled It was a factor that made Le unstable.

[0010]

[Means for Solving the Problems] Therefore, in the present invention, in the rail configuration of the single rail transport device for transporting personnel, the main rail 4 can be easily replaced and the installation fixing degree is not changed.

As a concrete structure, a spacer rail 9 which is to be inserted into the square pipe 2 at a connecting portion of the main rail 4 and which can be divided into two is provided at a central portion of the connecting metal fitting 8 and appears when the spacer rail 9 is removed. The connecting rail 8 can be moved into either of the main rails 4 to remove the main rail 4.

[0012]

【Example】

 An example of the present invention will be described below. As shown in Fig. 1, the main idea is to insert a spacer rail 9 divided into upper and lower parts into a central part of a connecting metal fitting 8 which is inserted into a connecting part of a main rail 4 which is formed by fixing 3 parts of a rack to a lower surface of a square pipe 2 and bolts and nuts. It was installed in.

The connecting fitting 8 is formed by bending a steel plate member 81 into a U shape, providing a long hole 84 in the U-shaped bottom portion at the center in the longitudinal direction, and a plurality of mounting holes 83 in the side plate. It is manufactured by arranging and welding a spacer color 82 between the side plates.

The spacer rail 9 is divided into upper and lower halves, the upper rail 91 is bent in a U shape, and the mounting holes 94 are provided on both side walls, and the side wall portions thereof are also uneven according to the mounting holes 94. It was done. The lower rail 92 is the same as the upper rail 91, but it is just inverted, and the rack 3 is welded to the lower surface and the reinforcing plate 93 with the mounting hole 94 is welded to the center of the upper surface. Is.

When replacing the rails, remove the bolts / nuts 41 connecting the main rails 4 and the connecting metal fittings 8, the bolts 95 mounting the spacer rails 9 and the nuts 96 to remove the spacer rails 9 vertically. , The connecting fitting 8 can be moved inside the square pipe 2, and the rail 4 can be removed.

[0016]

[Effect of the device]

 As described above, in the rail configuration of the single rail transport device for the purpose of transporting personnel, the spacer rail 9 is provided at the connecting portion of the main rail 4 to easily replace the rail 4 of the deformed portion of the rack. In addition to the fact that the main pillar 1 is not pulled out, there is a practical effect that the installation fixing degree does not change. Also, if the spacer rail 9 is made longer than the insertion dimension of the connecting metal fitting 8 that is inside the main rail 4, the bolts and nuts 41 on the main rail 4 side to be replaced and the bolts 95 and nuts 96 of the spacer rail 9 are replaced. It can be removed by moving the main rail 4 simply by removing it. In the above, all the bolts and nuts must be removed, but it is enough to remove the four bolts and nuts. , You can save the trouble.
