SU16377A1 - Mine Cage Buffer - Google Patents

Description

.To prevent falling from hitting the bottom prep. It proposes a device that quenches the inertial force of a falling cage by friction against springy steel strips, and an increase in rubber bands blocking the path of the cage. . , .

In FIG. 1 shows a general view of the device to the side; FIG. 2 - detail of the catching carriage and frames with rubber bands; FIG. 3 is a plan view of a frame with rubber bands; and FIG. 4 - detail of the spring stops.

The proposed device consists of a mine 1 located below mine 2, provided with vertical sliding guides 16 of spiral springs 4 pressed from the walls of the mine, with the carriage 5 moving vertically moving below the above strips 16 to trap the stand 16 without stopping, which carriage 5, when lowered, rests on several frames 6j arranged one above the other, on which they are pulled in the mutual directions of rubber e po- VOCs 10 zg1derzhivs1yuschie lowering ka-- ,; Rack 5 under pressure-falling stand. To prevent backward movement of the carriages upward under the squeezing force of the rubber bands, the upper part of the carriage is provided with spring stoppers 7, 8 that are sliding between the toothed racks 9 and, when the carriage moves upwards, engaging the teeth of the rails under the pressure of the spring 11, in the case of its stopping, bolts 12 serve as a guide between the vertical guides 16, pulling the guides 16 towards the wall. mines with the rotation of nuts 3. With ngshichii shallow mines and a small weight of the cage allowed the device only vertical spring guides without the device carriage 5 and peiM 6 with rubber strip.

The device consists in clamping the stand between the spring guides, and when there is a shortage of the friction force developing, the braking effect is supplemented by holding rubber tension npyauiH, the reverse squeezing of which is paralyzed by the stopper action of the stops & rails 9-.
