Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a telescoping gate, and particularly to an automatic opening/closing device thereof.

[Prior Art] As this type of automatic telescopic gate opening/closing device, for example, Japanese Utility Model Application No. 148046/1984 is known.

According to this proposal, a motor-driven endless wire is disposed within the opening/closing guide of a single central chevron-shaped rail for guiding the opening/closing of the telescopic gate, and the wire is connected to the tip running frame of the telescopic gate through the slit of the opening/closing guide. The u-blocks are connected by connecting fittings, and the motor is driven by this, and the endless wire is moved between the pulleys at both ends to pull the telescopic gate in the horizontal direction.
It is said that this was made to open and close.

[Problem to be solved by the invention] However, when using wire, elongation is a problem, but in this case too, the endless wire receives the opening and closing load of the telescopic gate as a tensile force. , it is inevitable that the endless wire will gradually stretch due to repeated opening and closing.

Stretching the endless wire will cause a dimensional error between the opening and closing width of the telescoping gate that was originally set, so for example, the telescoping gate may not be able to open or close to the specified position, or the motor drive and This results in a time lag between the start of opening and closing, and therefore, the above proposal still has the problem that durability as an automatic opening/closing device cannot be ensured.

Generally speaking, telescoping gates are often used in carports, factories, and other places where vehicles pass through, but the above proposal is said to have a slit directly in the opening/closing guide of the chevron-shaped rail, so it is difficult for vehicles to pass through. This may cause deformation of the opening/closing guide, making it impossible for the opening/closing guide to guide the opening/closing of the telescopic gate, or the reduction in the slit width may impair the movement of the connecting member, resulting in the inability to open/close the telescopic gate. Therefore, the above-mentioned proposal is subject to the restriction of the installation location, which means that it cannot be installed in a place where vehicles pass through where automatic opening and closing is desired.

The present invention was made in view of such circumstances,
The challenge is to ensure smooth opening and closing of the telescopic gate under the special conditions of being installed outdoors on the ground, exposed to wind, rain, mud, and other dust, and with vehicles passing through, and with excellent durability. To provide an automatic telescopic gate opening/closing device which is not limited by installation location, is easy to install, and allows inspection and cleaning as required.

[Means for Solving the Problems] The present invention uses a motor-driven screw rod and a screw block screwed thereon to open and close a telescoping gate that is stable and reliable and has excellent durability, and also solves the above problems. Along with this, a self-cleaning brush for the screw rod mudguard was added, and these were housed in a rod case to form a rod unit, which was removably fitted into the outer case and buried underground, and was installed as a retractable gate. and a screw block, and the opening/closing guide of the telescoping gate is constructed as a means for regulating the positional relationship between the telescoping gate and the rod unit, which is separate and independent from the rod unit.
A rod unit in which a screw block for advancing and retracting screwed onto the screw rod and a self-cleaning brush for mudguarding the screw rod cooperating with the screw rod are housed in a rod case having a horizontal slit, and the rod unit is removably fitted. The outer case is embedded in the ground, the connecting fitting connects the extensible gate end running frame and the screw block inside the rod unit through the horizontal slit of the rod case, and the extensible case regulates the positional relationship between the rod unit and the extensible gate. The present invention relates to an automatic telescopic gate opening/closing device characterized by comprising a gate wheel and an opening/closing guide for the wheel, and the gist of the invention is a means for solving the above problems.

[Example] The present invention will be described in more detail with reference to the drawings showing the examples. Fixed frame, tip running frame and intermediate running frame of gate A, 4 is a link member that constitutes a telescopic link mechanism,
Reference numeral 5 indicates a fixed support shaft on which these are rotatably mounted, 6 indicates a rolling wheel provided on an appropriate intermediate running frame 3, and 7 indicates a door stop frame for opposing the leading end running frame 2.
10 is an opening/closing guide that guides the opening and closing of the telescopic gate A and is also an element of automatic opening/closing device B; 20 is a rod unit of automatic opening/closing device B; 21 is a rod case; 24 is a screw rod; 30 is a screw block; 35 is a self-cleaning device. A brush and 37 indicate connecting fittings, respectively.

Rod unit 20 in automatic opening/closing device B
The screw rod 24 is attached to the rod case 21.
A screw block 30 for forward and backward movement screwed onto the screw rod 24 and a self-cleaning brush 35 for mudguarding the screw rod 24 which operates together with the screw block 30 are housed therein.

The rod case 21 is made of aluminum and has a long rectangular cross section and is made of aluminum and has a horizontal slit 22 extending over the entire length in the longitudinal direction on one side thereof.

The screw rod 24 is made of forcedly twisted stainless steel material and has a series of male screws 25 engraved on its surface, and is long enough to cover the opening/closing width of the telescopic gate A. It is housed in the rod case 21 so that it can freely rotate in both forward and reverse directions.

That is, this storage is carried out by supporting an auxiliary shaft 25 extendedly connected to both ends of the screw rod 24 on bearings 27 arranged at both ends of the rod case 21, and tightening each pair of nuts 27 from both ends. In particular, the bearings 27 are installed in the rod case 21, and one of the auxiliary shafts 26 is connected to the motor shaft 41 of the motor 40 via a shaft coupling 29. , the rod unit 20 is rotated by a motor 40 installed externally.

On the other hand, the screw block 30 is constructed as a thick plate block having a female screw 31 carved in the central through hole of the same stainless steel material, and the female screw 31 is engaged with the male screw 25. Accordingly, this screw block 30 is screwed onto the screw rod 24 of the rod unit 20 so that it can freely move forward and backward within the rod case 20 as the screw rod 24 rotates.

The screw block 30 in this example is a block case 3 for stable opening and closing of the telescoping gate A.
The block case 32 is fitted into the block holder hole 34 of No. 2, and a presser plate 36 is screwed and fixed to the block case 32 to form a unit-like structure, and is housed in the rod case 21.

The block case 32 has a through hole 33 in the center thereof through which the screw rod 24 passes, so that the forward and backward movement of the screw block 30 by the above-mentioned screw is not obstructed.

The self-cleaning brush 35 is constructed as a thick-walled disk, and its central through hole is connected to the block case 3.
It is arranged and fixed on the side surface of the block case 32 on the advancing and retreating side so as to coincide with the through hole 33 of No. The attached dust, such as mud solidified by rainwater, which is attached to the male thread 25 of the screw rod 24 is removed and cleaned. The rod unit 20 is designed to have a self-cleaning function.

The rod unit 20 constructed in this way is fitted into the outer case 23 and placed underground so that it is not affected by passing vehicles.

The outer case 23 is also made of aluminum and is made of an elongated piece having an upward U-shaped opening with overhanging fins on both sides, and the rod unit 20 is fitted into the outer case 23 through this U-shaped opening. As a result, the rod unit 20 is detachable by being lifted upward to enable inspection, cleaning, etc.

On the other hand, the connecting fitting 37 is made of thick-walled steel and has an inverted L-shape in this example, and its horizontal piece is screwed into the lower end of the tip running frame 2 of the telescopic gate A with a screw 38.
At the same time, the vertical piece is also screwed to the holding plate 36 fixed to the block case 32,
Thereby, the leading end traveling frame 2 and the screw block 30 in the rod unit 20 are connected. At this time, the connection is made so that the connection fitting 37 passes through the horizontal slit 22 of the rod case 21, so that the connection fitting 37 moves the tip traveling frame 2 in accordance with the forward and backward movement of the screw block 30.

By the way, the wheels 6 of the telescoping gate A and the opening/closing guide 10 of the wheels 6 guide the opening and closing of the telescoping gate A and always regulate the positional relationship between the rod unit 20 and the telescoping gate A. The screw block 30 is screwed onto the screw rod 24 with the screw block 30 and the leading end traveling frame 2 connected by the connecting fitting 37, thereby ensuring the strictness of the positional relationship.

Regarding the automatic opening/closing device B according to the above configuration,
By driving the motor 40 by a switch or a detection device, the screw rod rod 24 is rotated, and the screw rod 30 is moved to the rod unit 2.
0, move the tip traveling frame 2 connected to the screw block 30 through the horizontal slit 22, and smoothly move the telescopic gate A by regulating the positional relationship of the wheels 6 and the opening/closing guide 10 of the wheels 6. It will be opened and closed.

The illustrated example is as described above, but in carrying out the present invention, the telescoping gate is constructed such that the link member forms a horizontal telescoping link mechanism, and the screw rod is constructed by twisting aluminum extrusion material. In addition, the male thread of the screw rod is formed by cutting, the screw block is used in the form of a nut without using a rod case, and the connecting fitting is directly connected to the screw block, and the screw rod is supported.
