Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a horizontal sliding gate, and particularly to an automatic opening/closing device thereof.

[Conventional technology]

For example, Utility Model Application No. 59-82178 is known as this type of automatic horizontal sliding gate opening/closing device.

According to this, an upward rack gear is attached and fixed to the entire length of the lower part of the gate, and a rack pinion that meshes with the rack gear is provided at a fixed position, and the rack pinion is driven by a motor.
The gate will be opened and closed along the ground guide rail.

[The problem that the idea aims to solve]

However, in this case, it is necessary to attach a rack gear along the entire length of the lower part of the gate, so the automatic opening/closing device tends to be relatively expensive.Also, since the rack gear faces upward and is exposed, there is no possibility of mud etc. Dirt and foreign matter tend to adhere to the rack pinion, and there is a possibility that dirt and foreign matter will get caught between the rack pinion and the pinion gear, damaging the gearing of the rack pinion and making it impossible to open and close. It was also dangerous because the teeth were exposed.

This invention was made in view of such circumstances,
The problem to be solved is to provide an automatic horizontal sliding gate opening/closing device that always opens and closes stably and reliably and without danger, for horizontal sliding gates that are normally installed outdoors.

[Means to solve the problem]

The present invention is a gate that is normally installed outdoors in this way, and has a screw rod that is arranged and fixed in a floating manner on the ground so that the opening and closing is parallel to the ground guide rail, and a screw block that is fixed to the gate. In order to ensure stable opening/closing and to prevent danger, a mud scraping member is provided to remove dirt from the rod cover and screw rod. A motor-driven screw rod in the door bag section that is arranged and fixed floating on the ground parallel to the ground guide rail for guiding the opening and closing of the gate, a rod cover to protect the screw rod, and fixed to the lower position of the gate via a bracket. The invention relates to an automatic horizontal sliding gate opening/closing device characterized in that it is equipped with a gate fixing screw block having mud scraping members for removing dirt from the screw rods at the front and rear ends, and the above problem is solved by using this device as the gist of the invention. It was used as a means of

〔Example〕

The present invention will be described in more detail below with reference to drawings showing embodiments. 1 is a horizontal sliding gate, 2 is an automatic opening/closing device for the gate 1, 11 is a guide column, 12 is a ground guide rail, 13 is a door roller, 14 is the door stop support, 1
5 indicates a fence with one back side serving as a door pocket.

The automatic opening/closing device 2 basically includes a screw rod 21 and a screw block 26.

Screw rod 21 is made of aluminum alloy.
A long bar made of steel or the like is cut or twisted. This screw rod 21 is parallel to the above-mentioned ground guide rail 12 for guiding the opening and closing of the gate 1, and is placed in a raised position at a height slightly away from the ground surface in order to prevent the adhesion of dirt and foreign matter as much as possible. The arrangement is fixed by being held by a pair of bearings 23 so that

At this time, the length of the screw rod 21 corresponds to the width of the gate 1, that is, the opening/closing width. The end portion is placed on the guide column 11 to prevent it from occurring.

In contrast, the screw block 26 engages with the screw rod 21 and
The screw block 26 is made of hard synthetic resin, cast metal, etc. and has a rod engagement hole so as to move in the longitudinal direction of the screw rod 21 in accordance with the rotation of the gate 1. It is fixed via a bracket 27 at a lower position on the side end of the door pocket in the width direction.

The screw rod 21 and the screw block 26 are further provided with measures to ensure stable opening and closing and to prevent danger.That is, the screw rod 21 is provided with a mechanism for moving the screw block 26 over almost its entire length. An aluminum alloy rod cover 24 having a downward opening groove and through which the screw block 26 is inserted is provided to cover the screw rod 21, thereby preventing the screw rod 21 from being exposed and preventing dirt from adhering to it. It protects against danger and prevents danger.

The screw block 26 also has mud scraping members 2 at its front and rear ends for removing dirt from the screw block 26.
8 are integrally provided. This mud scraping member 28
In this example, the screw rod 21 has a gear-shaped ratchet fitting having a through hole corresponding to the outer diameter of the screw rod 21, and the edge of the through hole slides on the surface of the screw rod 21. The rod cover 24 is provided with a brush that slides into contact with the uneven surface of the rod cover 24 and the inner surface of the rod cover 24.

As described above, the mud scraping members 28 are provided at the front and rear ends of the screw block 26, so they remove dirt and foreign matter such as mud that adheres to the screw block 21 when the screw block 26 moves in both directions. By ensuring reliable engagement between the screw rod 21 and the screw block 26, the opening and closing of the gate 1 is always stable and reliable. The engaging end is covered to prevent danger to the worker due to entanglement, etc.

Therefore, the gate 1 equipped with the automatic opening/closing device 2 of this example
By driving the motor 22 disposed at the end of the screw rod 21, the screw rod 21 is rotated, and the screw block 26 fixed to the gate is moved horizontally, so that the gate 1 is always maintained. It is guided by the ground surface guide rail 12 to open and close stably, reliably, and without danger.

Reference numeral 25 in the figure indicates an angle member vertically disposed on the ground surface to securely hold the rod cover 24.

The illustrated example is as described above, but when implementing the present invention, specific materials, shapes, structures, dimensions, and quantities of the ground guide rail, motor, screw rod, rod cover, mud scraping member, and screw block will be used. , these arrangements, relationships, additions, etc. can be changed in various ways as long as they do not go against the gist of the invention, and are not particularly limited to what has been shown or described above.

[Effect of idea]

As described above, the present invention consists of a motor-driven screw rod in the door bag part which is arranged and fixed in a floating manner on the ground parallel to the ground guide rail for guiding the opening and closing of the gate, a rod cover for protecting the screw rod, and a rod cover for protecting the screw rod at the lower part of the gate. The gate fixing screw block is fixed in position via a bracket and has mud scraping members at the front and rear ends for removing dirt from the screw rod. The U-block can be moved horizontally to open and close the gate, and the rod cover temporarily prevents dirt and foreign matter from adhering to the screw rod. To provide an automatic horizontal sliding gate opening/closing device that secondaryly prevents dirt from getting caught between u-blocks and always stably and reliably opens and closes a gate normally installed outdoors.

Further, in the present invention, since the screw rod is not exposed, dangers associated with its rotation or engagement with the screw block are prevented, and safety can be ensured to a high degree.
