Abstract

Use: cleaning and maintenance of bins. SUMMARY OF THE INVENTION: A device for cleaning the inner surface of containers contains a cleaning work unit, made in the form of plowshares and located on a boom arm that is rigidly connected to the carrier pipe. The carrier is located in the central part of a flat platform. The ploughshare is mounted on a connecting rod that is hinged to the crankshaft, the latter is kinematically connected to the drive of the cleaning element through a chain transmission. The carrier rotates from the drive and during the cleaning, the ploughshares can move in the horizontal and vertical planes. The platform is suspended on three flexible rods, while the guide elements, made in the form of skis, are installed along the platform perimeter. During the cleaning process, the ploughshares can be fixed in different positions 4 silt cl

Description

The invention relates to the cleaning and maintenance of vertical cylindrical bunkers in the coal industry and other sectors of the national economy.

A known installation for the mechanical cleaning of the hopper, containing a scraper winch mounted on the foundation, working and single ropes, the ends of which are attached to the drums of the winch on a swivel tee carrying measles.

A disadvantage of this device is that it is only suitable for carrying out work on cleaning only the hoppers of the cervical type. In addition, this device cannot be used to carry out technical inspection and repair of the bunker.

A device for cleaning vertical cylindrical containers is known, which contains rotary-driven cages placed on a platform and associated brackets, at the ends of which cylindrical working bodies are rotatably fixed relative to the axes.

The drawback of the device is that it, due to the characteristics of the working body (cylindrical rollers with brushes), is intended only for removing thin layers of adhered material from the walls of cylindrical containers, and i also because its platform is not designed for repairing them.

The purpose of the invention is the expansion of functional (along with cleaning, use of the device for the production of inspections and repairs in the bunker) and technology |

GO

(removal of more massive layers of adhered material by varying the nature of the effect of the device's working organ on the adhered material) capabilities.

This goal is achieved by the fact that the device contains a rotary carrier on a platform with a rotational drive around a vertical axis and a radial boom arm associated with it, which houses a crank-type operating mechanism, the actuating element of which is in the form of a plowshare, which is fixed at the end of the rod-rod with the possibility of incorporation into the material when moving in horizontal and vertical planes, while the rod is pivotally connected to the crankshaft interacting through a chain in front of gears and transmission shafts from rotational drives, and the platform is made in the form of a shelf with suspension on at least three ropes with the possibility of movement inside the bunker and equipped with guide skis.

Figure 1 shows the device placed in the bunker, a general view; figure 2 - section aa in figure 1; fig.Z - node I in figure 1; FIG. 4 is a diagram of a crank drive operating mechanism.

The device contains a platform 1 suspended on at least those ropes 2, enveloping beams 3 and held by winches, a pipe-carrier 4 with a ring gear 5 in its upper part, a drive 6 of turning the pipe-carrier connected with its gear ring 5 conical gear 7, bracket-boom 8, rigidly connected to the carrier pipe 4 in the lower part, the operating mechanism of a crank-thrust-connecting rod type, including a crankshaft 9, a connecting rod 10 pivotally connected to it bracket 8, guide bushing 12, vertical shaft 13, upper Gear 14 of which engages with gear 15 of drive 16, and lower gear 17 with a bevel gear 18 of an intermediate roll 19 on which an asterisk 20 is mounted, connected via an endless chain 21 with an asterisk 22 mounted on a crankshaft 9 hinged on crown 8. The platform for preventing rocking is equipped with skis 3.

The device works as follows.

For the proposed device, there are two modes of operation - the mode of removal of material by a strip in a circle and the mode of raking material.

In the mode of removal of material by a strip when the working body moves along a circular trajectory, the rod 10 with the plowshare 11 is in a fixed position with respect to the bracket 8.

position As a rule, in this mode, the rod 10 with the plowshare 11 is located radially (in Fig. 1, this position is shown by a dotted line), however, if necessary, there may be other positions convenient for

0 impact on suspended bulk material.

After full rotation of the carrier pipe 4 with the bracket 8 by 360 °, the platform 1 is lowered by an amount equal to

5 width of the removed strip of material. The operation of the device in this mode is most effective at a relatively uniform thickness of the material’s bunker adhering to the walls.

0 In the case when there is a significant non-uniformity of the thickness of the adhered material, as well as a considerable compaction thereof, the mode of raking the material is used. This mode can be realized both in the process of rotation of the carrier pipe 4 and in its stationary position.

The use of the device allows to significantly reduce labor costs and to increase the cleaning efficiency of the bunkers while at the same time increasing process safety.
