Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water gate, and more particularly to a water gate that is provided with a gate lifting mechanism above a gate-shaped frame for guiding the gate.

[Prior art] As shown in Figure 3, this type of conventional water gate has the following structure:
Three high supports 3, 3A, 3B are erected on the upper surface of the upper base 2 of the gate-shaped frame body 1 for guiding the door body,
A driving shaft 5 having a manual handle 4 is provided on the upper part of the central support 3, and left and right screw rods 7, 7A to which the door body 6 is connected are inserted into the left and right supports 3A, 3B. Cylindrical body 8 that accommodates screw rods 7, 7A
A screw lever elevating mechanism 9 for connecting the driving shaft 5 to the left and right screw rods 7, 7A at the tops of the three supports 3, 3A, and 3B was provided without being housed in the box.

[Problem to be solved by the invention] In the above conventional technology, each support 3, 3A, 3
Since the main drive shaft 5 is connected to the left and right screw rods 7, 7A through the screw lift mechanism 9 at the top of B, the cylinder 8 that accommodates the screw rods 7, 7A is divided by the height a of the supports 3, 3A, 3B. As the length b becomes longer, the strength becomes weaker and the door body 6 becomes larger and dangerous.
The structure is complicated, requiring a stopper mechanism to prevent the vehicle from descending. Furthermore, since the screw lifting mechanism 9 is not housed in a box, it is subject to severe corrosion and is prone to breakdowns, making maintenance difficult, as well as being easily penetrated by moisture and dirt, and easily deformed by external forces. It was hot.

SUMMARY OF THE INVENTION An object of the present invention is to provide a water gate that is small and easy to maintain, prevents corrosion and the intrusion of moisture and dirt, and eliminates the need for a stopper mechanism.

[Means for Solving the Problems] The present invention provides a water gate equipped with a gate lifting mechanism above a gate-shaped frame body for guiding the gate body, in which a manual handle is provided above the upper base of the gate-shaped frame body. , a vertical rod is provided below the manual handle for vertically transmitting the rotation of the manual handle via a main drive shaft, and a pair of left and right horizontal rods are provided for horizontally branching and transmitting the rotation of the vertical rod via bearings, A pair of left and right screw rods that transmit the rotation of each horizontal rod via a cap gear and move up and down are inserted vertically into the left and right sides of the upper base,
A door body is provided at the lower end of this screw rod, and the horizontal rod, bearing, and cap gear are housed in a box body, and on this box body, there are a central cylinder body that stores the vertical rod, and left and right cylinder bodies that house the screw rods. It is a water gate consisting of an upright structure.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the guide grooves 11B of the left and right guide columns 11A of the portal frame body 11
A box body 13 formed by front and rear U-shaped steels 13A, left and right side plates 13B, and upper and lower plates 13C is provided on the upper surface of the upper base 11C of the gate-shaped frame body 11 so as to be movable up and down. A central cylindrical body 14 is erected at the upper center of the box body 13, and this central cylindrical body 1
Main drive shaft 16 with manual handle 15 on top of 4
A vertical rod 17 for vertically transmitting the rotation of the driving shaft 16 is provided in the central cylindrical body 14, and the box body 13
A bearing 18 with a built-in head gear (not shown) is installed in the center of the box body 13 to branch and transmit the rotation of the vertical rod 17 horizontally to the left and right, and a pair of left and right shafts are provided inside the box 13 to transmit the rotation branched and transmitted horizontally to the left and right. Install horizontal rods 19 and 19A,
Bearings 22 with built-in cap gears 21 are provided on the left and right sides of the box body 13 to transmit the rotation of the horizontal rods 19 and 19A to a pair of left and right screw rods 20 and 20A for raising and lowering the screw rods 2.
0.20A to the upper base 11C and the box body 13
A door body 12 is connected to the lower ends of the screw rods 20, 20A, and left and right cylinders 23, 23A are erected on the left and right sides of the box body 13 to accommodate the screw rods 20, 20A. Further, the horizontal rods 19, 19A and the bearings 18, 22 housed in the box body 13 constitute a screw rod lifting mechanism 24. Also, main drive shaft 1
The height of 6 may be the same as the conventional one shown in FIG.

When the main drive shaft 16 is rotated by operating the manual handle 15, this rotation is transmitted downward by the vertical rod 17, and then branched and transmitted to the left and right by a pair of left and right horizontal rods 19, 19A via a bearing 18. At the same time, it is transmitted to the pair of left and right screw rods 20, 20A via the bearing 22 built into the head gear 21, whereby the screw rods 20, 20A move up and down, and the door body 12 opens and closes the water gate along the guide groove 11B.

[Effects of the invention] Since the present invention is constructed as described above, it has the following effects. In other words, the rotation of the main drive shaft 16 is
The transmission is transmitted downward through the vertical rod 17 in the box body 13, and branched to the left and right through the horizontal rods 19, 19A in the box body 13. Length to top c
is compared to the conventional length b shown in Fig. 3.
The height of B is shortened by a, and similarly screw rods 20, 20A
Since the length of is also shortened, it becomes compact and has excellent strength. Furthermore, since the screw lifting mechanism 24 is located directly above the upper base 11C and housed in the box body 13, the height a shown in FIG. 3 becomes zero.
Since the left and right supports 3A and 3B are also removed, the size is further reduced. In addition, the screw lever lifting mechanism 24 is attached to the upper base 11C.
Since it is housed in the box body 13 directly above it, there is no fear of corrosion and the intrusion of moisture and dirt can be prevented, making maintenance management easy. Furthermore, as shown in Figure 3, in the conventional device, the horizontal rod was installed at the top, so it was necessary to pass under the horizontal rod or turn around to the side, but in the present invention, it is installed at a lower position. It is possible to secure scaffolding without getting in the way during work, and improve work efficiency. Moreover, even if external force is applied, there is no fear of damage and physical changes can be prevented. In addition, the rotation of the main drive shaft 16 is controlled by the vertical rod 17, the bearing 18 with a built-in cap gear, and the horizontal rods 19, 19A.
and the screw rod 2 by the bearing 22 built into the head gear 21.
Since the power is transmitted to 0.0 and 20 A, there is no need for a stopper mechanism to prevent the door body 12 from lowering, resulting in a simple structure.
