Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gate used for a large-scale entrance and exit of a factory or the like whose road surface is not smooth, and particularly to an electric open / close gate that can be self-propelled without the need to install a rail on the ground.
[0002]
[Prior art]
Conventionally, gates (gates) used for entrances and exits of factories and company buildings are relatively large and often have a steel structure in order to provide high strength. Therefore, the weight of the gate is enormous, and a configuration in which the gate can be opened and closed by rolling wheels provided on the gate on a rail arranged on the ground is generally used. In addition, recently, there is a configuration in which an automatic opening / closing operation can be performed electrically or mechanically instead of an opening / closing operation by human power.
[0003]
The electric gate disclosed in Japanese Patent Application Laid-Open No. 5-5388 has a structure in which a gate body having a door is moved to open and close on a rail laid on the ground, and includes a rotation drive device including a rack and a pinion. This is an example. In addition, the non-rail type slide gate disclosed in Japanese Patent No. 2678415 is configured to support the gate body by a slide box that is disposed on the ground and includes a plurality of guide rollers.
[0004]
[Problems to be solved by the invention]
However, in the electric gates disclosed in JP-A-5-53 8 8 No., the automatic opening and closing an electric are possible, it is necessary to provide a rail on the ground. The non-rail type sliding gate described in Japanese Patent No. 2678415 does not need to be provided with a rail. However, because of the configuration in which the gate body is supported by the upper and lower guide rollers, the gate body is in a retracted position and a closed position. Regardless of this, it is necessary to dispose the slide box at a predetermined position on the passage.
[0005]
An object of the present invention is to dispose a rail for moving a gate and other guides on a passage in a closed position of a large and heavy gate body (hereinafter referred to as a gate), and can be automatically opened and closed. An electric open / close gate is provided.
[0006]
[Means for solving problems]
In order to achieve the above object, the invention according to claim 1 is a gate that is movable between a retracted position for opening the passage and a closed position for closing the passage, and is provided with a driving device including driving wheels.

[0016]
As shown in FIG. 1, the electric open / close gate according to the present invention includes a gate body 1 and a guide member 2 that are movable between a closed position A for closing the passage 5 and a retracted position B for opening the passage 5. It is a gate. In this embodiment, the gate body 1 is composed of four units 1a, 1b, 1b, 1c. The unit 1a is a gate unit provided with a drive device, and when the passage 5 is closed, the gate body 1 is the foremost part when moving from the retracted position B to the closed position A and becomes the leading vehicle. The intermediate unit 1b is a unit having only driven wheels and does not include a driving device. The unit 1c is the last unit and includes a driving device as in the case of 1a.
[0017]
Power is supplied to the driving device through the cable 8. The cable 8 is configured to be wound up by a rotary reel 9 installed at the back of the retracted position B. When the gate body 1 moves to the closed position A, the cable 8 is also pulled out together, When the main body 1 moves to the retracted position B, the main body 1 is automatically wound around the rotary reel 9.
[0018]
The gate body 1 may be opened and closed by controlling the power supply to the driving device, may be a switch operation of a control panel (not shown), and remote control using radio is also possible.
[0019]
The retreat position B is formed by a lead-in portion 6 having a size enough to accommodate the entire gate body 1. A guide member 2 is disposed in the vicinity of the retreat position B and on the outer side of the passage 5 so as to guide the guide rail 3 disposed in each unit constituting the gate body 1. . Therefore, it is not necessary to install a rail, a guide guide, or the like on the ground of the passage 5, and each unit having wheels is configured to be movable in a predetermined direction by the guide member 2.
[0020]
The unit 1a will be described with reference to FIGS. 2 (a), 2 (b) and 2 (c). A large number of lattice members 21 are disposed between the horizontal member 20 having a length of about 5 m in the horizontal direction and the base 22. The pedestal 22 is a rectangular frame in which two long side members 22a and two short side members 22b are fixed by welding or the like.
[0021]
The driving wheel 10 and the driven wheel 11 are respectively disposed at the front end portion and the rear end portion of the pedestal 22, and the guide rail 3 a is interposed via the pedestal member 24 in the upper portion that cuts through the substantially central portion in the longitudinal direction of the pedestal 22. It is arranged. The guide rail 3a is connected in series with the guide rails of other units to form the guide rail 3, and is guided by the guide member 2 to restrict the traveling direction.
[0022]
The drive wheel 10 is composed of four wheels. Each of the two wheels penetrates the two long side members 22a facing each other, and at the same time, the wheels 10b are fixed to both ends of the drive shaft 10a that is rotatably mounted. ing. The drive shaft 10 a is rotationally driven via the drive transmission unit 13 with the driving force of the motor 12. The drive transmission unit 13 is generally a drive transmission method using a toothed belt, a drive transmission method using a gear, or the like, and is not particularly limited.
[0023]
The driving force of the motor 12 placed on the base plate 23 spanned between the two long side members 22a facing each other is transmitted to the driving shaft 10a via the driving transmission unit 13, and further the second driving transmission unit. In this configuration, the second drive shaft 10 c is driven via 14. That is, the drive wheel 10 forms a four-wheel drive type drive device having four wheels 10b that are rotationally driven.
[0024]
Although the four-wheel drive type is configured to drive four wheels from a single motor, the four-wheel drive type may be configured such that each of the four wheels is independently rotatable and a drive motor is provided for each.
[0025]
The driven wheel 11 is configured such that a wheel 11b is rotatably mounted on a shaft 11a disposed through two opposing long side members 22a. Also, like the driving wheel 10, four wheels are provided. By arranging the four wheels 11b, even if the road surface is uneven, any of the four wheels is in a grounded state, and the gate body 1 of the electric open / close gate is reliably moved.
[0026]
A guide rail 3a having a rectangular cross section is stretched over the base member 24 fixed to the two opposing short side members 22b in parallel with the long side member 22a. The guide rail 3a is a member for guiding the gate main body 1 so as not to swing left and right during traveling movement, and is configured to be engaged and guided with a guide member 2 described later.
[0027]
A unit 1b shown in FIGS. 3 (a) and 3 (b) is an intermediate vehicle that does not have a drive device, and has a configuration in which driven wheels 11 are disposed at both ends of the pedestal 22 in the longitudinal direction. Other configurations are the same as those of the unit 1a, and will not be described in detail here.
[0028]
4A and 4B show the unit 1c used at the end. The unit 1c has a configuration in which one driving wheel 10 and one driven wheel 11 are disposed in the same manner as the unit 1a, and each unit 1a, 1b, 1c is integrally configured to form the gate body 1. Drive wheels are provided at both ends.
[0029]
The guide rail 3c is configured in the same manner, but one end of the guide rail 3c is extended long, and when the gate body 1 completely blocks the passage 5, the guide rail 3c extending backward is also provided. The guide member 2 and the engagement state are maintained.
[0030]
The guide member 2 will be described with reference to FIGS. The guide member 2 has a structure in which struts 2a and 2b erected on the ground D are integrally connected, and horizontal frames 2c and 2d are attached to upper ends of the struts 2a and 2b, respectively. A pair of rotating rollers 4a and 4b are provided on the horizontal frames 2c and 2d, respectively, to guide the guide 3 of the gate body 1 by sandwiching it from both sides. The gap E between the rotating rollers 4a and 4b is slightly larger than the width e of the guide rail 3, so that the guide rail 3 can be easily slid.
[0031]
Further, the horizontal interval L between the horizontal frames 2c and 2d is approximately 1.5 meters, and is configured to be held at two points when the guide rail 3 is slid to prevent lateral vibration. Therefore, the gate body 1 having a total length of about 20 meters formed by connecting four units each having a length of about 5 meters can be configured to be slidable substantially linearly without causing lateral vibration.
[0032]
FIG. 6 shows an example of a connecting portion between the units 1a and 1b. The connecting pieces 7a mounted on both sides of the end of the pedestal 22, which is a rectangular frame of the unit 1a, and the connecting pieces 7b mounted on both ends of the pedestal 22 of the opposing unit 1b are connected to each other. The shaft 7c is loosely fitted and connected. The shaft 7c may be a single shaft having a length enough to penetrate two connecting pieces mounted on both ends of the pedestal 22, or may be two short shafts provided on each side. Good.
[0033]
Since the pedestal of each unit is loosely fitted with a single shaft, even if there is unevenness on the traveling road surface, the units bend with the shaft 7c as an axis to absorb the unevenness. be able to. In the horizontal direction perpendicular to the traveling direction, the connecting portions by the shaft 7c are provided on both sides of the end portion of the pedestal 22, and therefore cannot be displaced. That is, the relative positions of the units are displaceable in the vertical direction and are difficult to displace in the horizontal direction.
[0034]
Further, the connecting piece 7b may be a connecting piece 7b ′ having a long hole in the vertical direction. In this case, the units are not only bent at the connecting portion, but also shifted in the vertical direction, so that the vertically displaceable range is further increased.
[0035]
When the unit 1a and the unit 1b are connected to each other, the guide rail 3a and the guide rail 3b are arranged in a substantially straight line so that their end faces are in contact with each other. A book guide rail 3 is formed.
[0036]
A driving device having a driving gate in a front gate unit that is a leading vehicle and a rearmost unit that is a rearmost vehicle in which a plurality of units are connected to form a long gate body by the above-described connection configuration. Therefore, the gate body 1 moves the guide member 2 to the guide rail 3 both in the case of advancement from the retracted position B to the closed position A and in the case of retreating from the closed position A to the retracted position B. The first unit and the last unit are driven to drive while guiding, so that it becomes a so-called push-pull type driving method, and the directivity is improved and the vehicle is moved while keeping the linearity reliably. Can do.
[0037]
In particular, the large and heavy gate body 1 constituted by connecting a plurality of steel structure units is important to drive the front and rear units in terms of weight and length. is there.
[0038]
Further, since the drive wheels are of the four-wheel drive type, at least one or more drive wheels are grounded and travel on any uneven road surface, so that the driving force of travel can be reliably exhibited.
[0039]
Further, since it is not necessary to provide rails and guides for running the gate body 1 of the electric opening / closing gate on the road surface of the passage 5 which is the closed position A, the road surface which is originally not flat or a rail for another vehicle is not required. An electric gate that can be automatically opened and closed can be installed even on a road surface on which roads are arranged.
[0040]
【The invention's effect】
According to the first aspect of the present invention, the guide rail is disposed on the pedestal of the gate body in which a plurality of units are connected in a straight line , engaged with the guide rail, and the traveling direction of the gate body is restricted. Since the guide member is arranged in the vicinity of the retracted position outside the passage, there is no need to install a rail or the like on the passage where the gate body travels, and the electric open / close gate can automatically move straight to a predetermined closed position. Can be obtained. Further, since the relative positions of the units in the connecting portions connected in a straight line are determined to be displaced in the vertical direction while being position-regulated so as not to be displaced in the horizontal direction, the traveling road surface The concavity and convexity can be absorbed and the connected configuration can be maintained. In addition, the straight units can be maintained without shifting the units in the horizontal direction.
[0041]
According to the second aspect of the present invention, since the drive devices are disposed in the foremost part and the rearmost unit of the plurality of units connected in a straight line, the gate body connecting the plurality of units moves forward. When driving and retreating, the leading unit and the last unit are driven at the same time, so that it becomes a so-called push-pull type driving method, and the straightness of the gate body configured by connecting a plurality of units is achieved. Further improve .
[0042]
According to the invention of claim 3, since the driving device is a four-wheel drive type driving device , a plurality of driving devices can be reliably and straightly maintained even when the road surface is worse. It becomes possible to drive the gate body to which the units are connected .
