Description

Protection unit for winch with vibration absorption function {Protection Unit for Winch}

The present invention relates to an anti-vibration unit, and more particularly, in a winch for intermittently controlling and controlling the up and down opening / closing action of a water gate by transmitting a driving force, the vibration shock generated during the drive action of the winch is more stable. The present invention relates to an anti-vibration unit for a hoisting machine having a vibration absorbing function that is made to be absorbed and canceled by an efficient structure, thereby increasing durability of the machine (winder).

In general, water and sewage, urban sewage treatment plants, water treatment plants, agricultural irrigation canals and other rivers are used to install water gates, which are a type of repair facility, and such water gates are used for raising, lowering, opening and closing control. By controlling the flow rate to maintain the depth of water as well as to prevent the backflow of the water caused by the flood, etc. will be performed.

In addition, the opening and closing action of the water gate as described above is to be selectively controlled by the external power transmission relationship using a manual operation or a hoist according to the capacity and size of the water gate facility, and thus, various forms such as In the hydrological control means, in particular, the hoist 100, as shown in Figure 1, which is a configuration, which transfers the power generated from the electric motor 10 to the speed reduction device 20 through a variety of gear connection relationship By transmitting, it is to perform the function of automatically regulating the opening and closing action of the gate.

However, as mentioned above, the hydrostatic winding machine generates excessive vibration due to the driving action of the electric motor and the organic power transmission relationship of the various gears according to the driving action, and causes considerable operating stress on the device. Nevertheless, the above-mentioned conventional hydrostatic traction device does not provide any means for canceling or preventing such a vibration phenomenon, thereby lowering the durability of the device, providing a cause of frequent failures, and accordingly the service life It had a significant structural closure, such as shortening.

On the other hand, the above-mentioned hydrostatic traction machine, in order to smoothly generate the driving force and the stable transmission of the generated power, in the installation relationship, without being tilted or shaken, keeps the ground and the ground, and a solid fixed state Although it is an essential requirement to maintain it, the conventional hydrostatic hoist has a level of uneven or inclined surface of the place where it is installed. It was only a method of using a conventional approach, such as leveling the ground flat or inserting something that could be supported by the ground into the slanted bottom gap of the hoisting machine. There was also a considerable problem in the world.

Accordingly, the present invention has been made to solve the general problems, such as damage or malfunction of the device according to the vibration phenomenon;

Hereinafter, with reference to the accompanying drawings, a schematic configuration of the present invention will be described.

It is a combination which forms a series of organic coupling relationship, and consists of a fixed shaft 1, the support plate 2, and the buffer pad 3.

Here, first, the fixed shaft 1 is a means for stably mounting the dustproof unit according to the present invention to the winch 100, and, as such, the fixed shaft 1 is shown in Figs. As described above, the male thread N is formed on the outer diameter surface of the upper side as a circular pillar having a predetermined length, and the tightening nut 11 is fastened to the upper side where the male thread N is formed. The stop piece 12 which takes the form of a circular plate is integrally processed and formed in the lower outer side surface of the fixed shaft 1 again, and by the fastening nut 11 and the stop piece 12 which were formed in this way again, It is preferable to further include a gap adjusting portion 13 having a predetermined length between the tightening nut 11 and the stop piece 12.

At this time, the outer diameter portion of the lower end of the fixed shaft (1) is formed of an assembling screw surface (14) formed with male threads in order to engage with the support plate (2) to be described later.

In addition, the support plate 2 is a means for supporting the winch 100 in a stable form on the ground, such as, the support plate 2, as shown in Figs. As the center of the upper surface, a groove having a female screw structure, for example, a shaft connecting hole 21 for engaging the above-mentioned fixed shaft 1 is formed, and the pad mounting groove 22 inside the bottom of the support plate 2.
