Imagine that you are in a technical school classroom. There are classes. The teacher at the pulpit presents the course, and the students, as expected, sit at the tables and listen carefully. But then the theoretical part ends, and an unusual thing happens: the teacher, instead of inviting the students to go to the workshop or laboratory, asks them to stand in the aisles. Then he presses a button on the remote control, and the tables, as if on command, are lowered to the level of the seats. The motor rumbles... and the rows of tables slowly move under the pulpit! One and a half minutes - and the room is free for practical exercises.

Hydraulic class

Such a mobile mechanized class exists in vocational school No. 178 of the village of Atasu, Zhanaarkii district, Dzhezkazgan region.

Ten tables are installed in two rows on a frame welded from 90x90 mm corners. The seats rest on tubular frames welded to the frame. Tables have hydraulic cylinders instead of legs. There are twenty of them, all of them removed from decommissioned headers and rigidly connected to the frame. Single-acting cylinders - their rods are advanced under the pressure of oil. When the pressure is released, the stems lower under the weight of the tables. The control of raising and lowering the desks is carried out by the P75-23 hydraulic distributor located on the department console.

Oil is pumped into the distributor and then by a gear pump NSh-46 driven by an electric motor with a power of 10 kW and a speed of 960 rpm.

The entire hydraulic system is installed below the tables so that the oil displaced by the rods flows into the tank by gravity.

At the front of the frame, two guide sprockets rotate in bearings. The middle of the frame rests on rollers. In the back, too, stars, but leading ones. Right there, under the seat of the last desk, there is an electric motor with a power of 0,8 kW, with a speed of 1400 rpm and a worm gearbox with a gear ratio of 50. guide chains stretched along the metal strips and attached to them. The planks, in turn, are welded to the pins concreted into the floor. The support rollers roll straight across the floor.

Hydraulic class unit: 1 - frame, 2 - hydraulic cylinder, 3 - guide sprocket, 4 - chain

The pulpit is on a platform with a niche, like a garage, but without a gate. The dimensions of the write are such that the frame with the lowered tables fits in it entirely. Only guide chains remain on the floor.

All class tables are also set in motion from the remote control on the teacher's table - there is a reverse switch with a magnetic starter. But the movement of the frame, as soon as it takes some end position, may stop automatically. Pa front and rear desks for this there are limit switches. If necessary, the frame is quite easy to move manually.

We built such a class in our technical school. It is simple, reliable and allows you to maximize the useful area of the training workshop. The teachers, students and, of course, the technicians are satisfied - it has become much more convenient for them to clean the room.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Luminous Wound Dressing 30.08.2021

An antimicrobial bandage with fluorescent sensors was developed by scientists at the Australian Royal Melbourne Institute of Technology.

The bandage is able to glow under ultraviolet light if the wound does not heal properly. The dressing itself has the antibacterial and antifungal properties of magnesium hydroxide and is less expensive than silver-based dressings.

The glow is due to the fact that the infection makes the environment of the wound more alkaline. This causes magnesium hydroxide to fluoresce when exposed to ultraviolet light.

According to scientists, such a bandage will help monitor patients, since doctors will be able to check wounds without removing the bandage. If the usual bandage is removed, then there is a risk of infection with pathogens.
