Description

[Detailed Description of the Invention] The present invention relates to a lifting device for a small water gate that manually lifts and lowers a gate body.

Conventionally, the drive device that raises and lowers the gate body of the water gate was installed on the upper frame of the water gate pillar, so the drive device was located at a high place and could not be operated from the ground. A gangway was installed that spanned from the ground to the control console.

Therefore, the overall size increases, and each time the door body is opened/closed, it is necessary to go up and down the ramp, which is extremely troublesome.Moreover, the drive mechanism is exposed and exposed to wind and rain, so the durability is reduced. There were some flaws such as bad.

The present invention does not require the installation of ramps, etc., and the water gate post itself can also be used as the gear case of the hoisting machine, eliminating the need to provide a separate gear case from the water gate post as in the past, reducing costs and increasing durability. It is an object of the present invention to provide a lifting device for a water gate which can be improved and furthermore allows an operator to raise and lower a water gate pillar extremely safely while remaining on the ground without having to climb an upper frame located at a high place. In the water gate in which the gate body 5 is guided vertically by fitting both sides of the gate body 5 into the left and right side frames 3, 3 of the water gate column 1 whose upper part is connected by the upper frame 2, respectively. It is composed of a box-shaped frame in which the upper frame 2 of the water gate pillar 1 and both side frames 3, 3 are connected at the upper corners, and a hoisting machine is housed in the upper frame 2. A bundle having a height that can be manually operated on the ground is rotatably supported on the outside, and the bundle is connected in communication with a hoisting machine in the upper frame 2 and in the side frame 3. It is something.

The embodiment shown in the drawings will be described below. Reference numeral 1 denotes a water gate column consisting of an upper frame 2 and left and right side frames 3, 3 extending downward from both ends thereof. The upper part of the side frames 3, 3, above the part a partially buried under the ground, is constructed by connecting the inner frame 3a and the outer frame 3b, each having a U-shaped cross section, in series.
A is fixed to the deposit 4 by welding or other means.

5 has guide grooves 3c on both sides of the side frames 3, 3.
, 3c, and a guide vibro fixed to both sides of the door body 5, and a nut 7 at the top of the guide vibro 6, respectively.
．． 7 is fixed.

In the upper frame 2, there is provided a hoisting machine consisting of a horizontal shaft 8 and transmission cases 9, 9 which support both ends of the horizontal shaft and are equipped with a worm gear or a bevel gear, etc. 9 to the side frame 3,
3 guide i3c.

A screw rod 10 hanging inside 3c and interlocking with the horizontal shaft 8.
10 is screwed into the nut 7.7.

Further, a handle 11 is interlocked and connected to one end of the horizontal shaft 8 within the side frame so as to protrude outward from one side frame 3, and can be operated while slightly bending at the waist on the outside of the other side frame 3. A sprocket 14 attached between the inner frame 3a and outer frame 3b of the handle is connected to a sprocket 12 attached to the other end of the horizontal shaft 8, and a chain in the side frame 3 on that side. This is an interlocking connection via 715.

In addition, 16 in the drawing is a rubber sealing plate fixed along both edges of the inside of the door body 5 with a stopper 17 and screws,
Its tip side is in sliding contact with the inner surface of the side frame 3.3.

In the above-mentioned device, when raising and lowering the door body 5, a tall person should turn the handle 11 on the right side in the drawing, and a short person should turn the handle 13 on the left side.
5, the horizontal shaft 8 rotates, thereby rotating the screw rods 10, 10.
rotates and the door body 5 moves up and down.

Next, another embodiment of the present invention will be explained with reference to FIG.
This embodiment is the above-mentioned embodiment (however, the handle 13 is omitted).
A collar 18.18 is welded or simply joined to the upper surface of the nut 7.7, and the upper end of the collar 18.18 lowers the door body 5 the most and its lower edge is placed on the security deposit 4. The length is set to be higher than the maximum overflow water depth H in the joined state, and the nut 7.7 and screw rod 1
This prevents dirt, sand, etc. from entering the threaded part with 0.10.

As described above, the present invention guides the door body 5 up and down by fitting both sides of the door body 5 into the left and right side frames 3, 3 of the water gate pillar 1, whose upper part is connected by the upper frame 2. In such a water gate, the upper frame 2 of the water gate pillar 1 and both side frames 3, 3 are connected to each other at the upper corners of a box-shaped frame body, and a hoisting machine is installed inside the upper frame 2. A handle having a height that can be manually operated on the ground is rotatably supported on the outside of the side frame 3,
Since the handle is interlocked with the hoisting machine in the upper frame 2 and in the side frame 3, when the door body 5 is raised or lowered, the handle protruding from the outside of the side frame 3 can maintain a stable posture while on the ground. In addition to being extremely easy to operate, the dangerous lifting and lowering work of the door body 5, which was conventionally done on an extremely narrow upper frame located at a high place, can be performed safely on the ground.

In addition, although the water gates face waterways on both the upper and lower sides, creating an environment where there is a high risk of falling, the handle can be operated in a safe place outside the water gate, which prevents falls and accidents. can be prevented.

Moreover, the upper frame and side frame that make up the water gate pillar also serve as the transmission case for the transmission mechanism installed in the hoisting machine and/or the hoisting machine and the handle, so the transmission case is provided outside the water gate constituent members. There is no need for this, and the entire structure can be made compact while ensuring the protection and safety of the transmission device, and it can be provided at low cost.

Furthermore, by incorporating the hoist into the upper frame, it is possible to lower the center of gravity of the entire water gate and improve safety.
