Abstract
Description
Technical Field
[0001] The utility model relates to aperture plugging in the process of railway freight car inspection and repair, general aircraft maintenance and the like, and specifically is a universal aperture plugging device. Background Art
[0002] When railway freight cars are put into storage for inspection and maintenance at the factory or section, the accumulated water in the pipe system needs to be discharged. However, the pipe system of railway freight cars is numerous and complex. In order to improve the discharge efficiency of accumulated water, high-pressure air is generally introduced at the entrance of the pipe system, and the accumulated water can be quickly discharged from various drainage holes. The drainage holes are distributed in various places in the pipe system. Some drainage holes face the bottom braking system, and some drainage holes face the ground. The accumulated water in the car flows to the bottom of the car body through the drainage holes, which will cause the vehicle parts to rust, thereby affecting the braking safety of the vehicle; when the accumulated water in the car flows to the ground through the drainage holes, it makes the ground slippery. First, it causes the braking distance of the forklift to become longer, water to enter the inside of the pickaxe, and unstable take-off and landing; second, personnel are prone to slipping and falling, which is easy to cause safety hazards; third, special personnel need to be arranged to clean the ground, which increases the labor intensity of on-site staff. In order to prevent the discharged accumulated water from affecting other parts of the railway freight car and the on-site working environment, some of the drainage holes are blocked to allow the accumulated water to be discharged from specific drainage holes. Drain holes are usually blocked with rags, but the seal is not tight when the rags are used to block water, which makes it easy for water to leak. Summary of the invention
[0003] The utility model provides a universal aperture plugging device to solve the problem that the drainage hole plugs of railway freight car pipe systems have poor sealing effect and are prone to water leakage.
[0004] The utility model is realized by adopting the following technical scheme: a universal aperture plugging device, comprising a rubber barrel, a screw, a special-shaped pressing piece, a gasket, an eccentric handle, an eccentric handle pin and an arc-shaped gasket, the special-shaped pressing piece comprising a ring body, a nut being fixed in the middle of the ring body, the rubber barrel comprising a middle barrel body, a lower baffle being provided at the bottom of the barrel body, the area of the lower baffle being smaller than the area of the ring body in the special-shaped pressing piece, an upper baffle being provided at the top of the barrel body, the gasket being arranged above the upper baffle, the arc-shaped gasket being arranged above the gasket, through holes being provided in the middle of the gasket and the arc-shaped gasket, the bottom of the eccentric handle being provided with a pin seat, the bottom of the pin seat being provided with a A through hole is provided, and the pin seat at the bottom of the eccentric handle is located in the arc-shaped gasket. A vertical threaded hole is provided on the pin, and the pin is arranged in the pin seat. The screw comprises a first part rod body and a second part rod body. The diameter of the first part rod body is greater than the diameter of the second part rod body, and the diameter of the first part rod body is greater than the diameter of the through hole on the gasket, and the diameter of the second part rod body is smaller than the diameter of the through hole on the gasket. The first part rod body of the screw is located in the rubber barrel, and the bottom end of the first part rod body is threadedly connected to the nut on the special-shaped pressing sheet, and the second part rod body passes through the gasket, the arc-shaped gasket, and the through hole on the pin seat in turn and is threadedly connected to the pin.
[0005] By pressing the eccentric handle, the pin seat at the bottom of the eccentric handle will tilt upward, the screw will move upward along the axial direction, and the first part of the rod body will drive the special-shaped pressing piece to move upward. The special-shaped pressing piece generates a pulling force toward the center of the rubber barrel. The gasket blocks the upward movement of the first part of the rod body. The gasket generates a pressure toward the center of the rubber barrel, so that the barrel in the middle of the rubber barrel is forced to expand and the outer diameter becomes larger, thereby achieving the purpose of blocking the aperture. When in use, the rubber barrel is extended into the pipe to be blocked, and the eccentric handle is exposed outside. Pressing the eccentric handle completes the blocking of the pipe.
[0006] In the above-mentioned universal aperture plugging device, the area of the upper baffle of the rubber barrel is larger than the aperture of the blocked pipe; when the plugging device is used to plug the drainage pipe, the upper baffle of the rubber barrel can just block the pipe opening of the pipe body.
[0007] The utility model has the following advantages:
[0008] 1. By directly installing the aperture plugging device at the drain pipe or drain hole to be blocked, it has very good airtightness, effectively preventing the accumulated water in the vehicle from flowing to the bottom of the vehicle body through the drain pipe or drain hole, thus avoiding the rust of vehicle parts.
[0009] 2. This kind of tool can be promoted to the whole society and used in the whole field of railway, aviation, machinery manufacturing and maintenance and other piping systems, so as to solve the problem of difficult aperture plugging on a large scale and achieve a certain degree of cost saving and consumption reduction.
