Description

[Detailed description of the device]

[0001]

[Industrial applications]

  This device is suitable for construction sites or work sites where large trucks come in and go out. For more details on the gate drive mechanism that is supported at the entrance and exit of the A drive mechanism for an automatic gate for construction sites that automatically opens and closes with a drive motor and its drive unit. Regarding

[0002]

[Prior art]

  Temporary gates at the entrances and exits of construction sites where large vehicles such as dump trucks frequently come and go An accordion-shaped gate that can be folded left and right to expand or contract to open and close The rollers on the support rods attached to various places on the upper part of the door are fitted into the opening / closing guides of the gate beam and suspended. Hold it and let the lower part of the gate pass through the guide rope that crawls on the ground, and equip it, The gatekeeper with a wide gate is pulled by hand every time he / she goes in and out. The vehicle is guided by folding, unfolding and opening and closing.

[0003]   This gate has a cluttered construction site noise, dust and other environmental pollution in the surrounding area. And prevent accidents due to the entry of general passers-by other than construction personnel From the aspect of the dump truck, a dump truck that can carry in and out a large amount of earth and sand, ready-mixed concrete, building materials, etc. It is common to close the entrance of large vehicles such as racks with a gate. The need is particularly pronounced in urban areas with heavy traffic.

[0004]   Moreover, since it is installed at the entrance of a busy construction site, there are many near the gate. There may be a small amount of building materials brought in, other vehicles, etc. A large gate with a wide entrance that allows passengers to enter and exit Each time, it is required to open and close manually with human power. On the other hand, lack of manpower In recent years, this large size is for security guards who have relatively weak women or elderly men. The manual operation of opening and closing the gate is quite rigorous, and speedy gate opening and closing in this situation Was hopeless. Therefore, in urban areas with high traffic such as people and vehicles, Every time a large vehicle enters or leaves the site, it takes time to open and close the gates and enter the construction site. The large vehicles that are trying to In addition to reducing traffic, it also prevents people and vehicles from passing smoothly and causes traffic congestion. There was a problem.

[0005]   Therefore, it has been tried to automatically open and close the gates of large vehicle entrances and exits at construction sites. The drive mechanism is located at the entrance and exit of the temporary gate along the opening and closing direction. Equipped with a drive drum driven by a motor and a supporting drum that moves. Endless circular wire rope is stretched and driven on the drive drum. In order to prevent slippage and to transmit the driving force reliably, the drive section is constructed by winding it around multiple times. , A wire rope at the top of the opening and closing tip of the gate that folds and hangs freely at the gate It is made by connecting fixed parts, and the drive drum is rotated by the operation of the drive motor to wire. The rope was driven to open and close the gate that could be connected to a predetermined moving location.

[0006]   However, this wire rope drive mechanism increases the tension on both drums. By stretching it and winding it around the drive drum multiple times, To prevent slipping between the moving drum and the wire rope and to transmit the driving force reliably. Therefore, it is not possible to expect smooth and quick opening and closing drive, and the drive drive A very large resistance is added to the drive of the drum, and the spindle and wire rope of both drums Easy to get tired quickly.

[0007]   In particular, multiple windings of wire rope on the drive drum are neatly lined up Drives relatively smoothly at times, but the slack in the wire rope with a large load is large As it becomes, it becomes impossible to wind the winding part in order when driving At the same time, one of the unwinding parts can be unwound and pressed by the subsequent winding. May occur, which makes it difficult to drive smoothly, and eventually it becomes impossible to rotate. Trouble such as falling is easy to occur, and the frequency of maintenance increases.

[0008]   Furthermore, since the wire rope is tensioned, it is possible to play games at each site at the production factory. It is difficult to adjust and assemble to the width of the gate, and therefore it is possible to directly Since it will be attached in a cut-and-joint manner, the wire rope will be tensioned The special assembly of special equipment must be done at a complicated construction site. There were many problems such as poor installation efficiency and accuracy.
