    Roller supporting means for the lance tube of a long travel retracting soot blower includes a pair of castering-type roller assemblies having their castering axes non-vertical. Each roller assembly is counterweighted to such extent as to substantially statically balance the assembly about its castering axis.

    The invention relates to the cleaning of equipment from contamination and can be used in various areas of industry using heat exchangers.
    The aim of the invention is to increase the reliability of the cleaning device by reducing the wear of the blast tube.
    Fig. 1 shows a device for blowing soot; a general view; FIGS. 2 and 3 show a roller bearing device; in fig 4. roller assembly with divided parts.
    The device for blowing off soot contains a blast pipe 1 with nozzles that enter the internal cavity of a boiler or other heat exchanger, the surfaces of which must be cleaned. The supporting means for the blast tube includes a core structure 2 comprising support rails (not shown) along which the carriage 3 moves, designed to rotate the blast tube 1 and its longitudinal movement through the wall of the heat exchanger 4 and back. The passage means through which the blowing pipe passes has an air-cooled duct assembly 5, the Working agent leaves the nozzles of the blowing pipe 1 during its passage into the inside of the heat exchanger and is fed to the latter through the supply pipe 6 through the blowing valve 7 and - the swarm enters the blast pipe on which the pipe is slidably fixed. To maintain the free end of the blast pipe 1, there is a bracket 9 with a support 10 for roller assemblies fixed to the rod structure 2, the Support 10 contains a lever 11 with a bracket SG 12, designed as a bifurcated lever, the ends of which screws 13 through a wobble unit 5 suspended from the box air ohlazhdemi, bracket 12 fixed to the arm 11 by means of a threaded joint. Bearing 10 covers the blast pipe I from below. The loop formed by the support 10 has an octagonal shape, having in each of the two lower nodes rigid flat brackets 14 and 15, located in a plane perpendicular to the radial line relative to the axis of the blast tube 1 and approximately 45 ° from the horizontal. Each of the two brackets 14 and 15 has a roller carriage 16 placed
    in the trunnion by means of bearings 17 and 18, which can be rotated around an axis 19, perpendicular to the axis of the blow tube 1, Bearings 17 and 18 tightly cover CTeHKahm 20 and 21, which protrude from the clips 14 and 15 and help protect the bearings from contamination. The protruding shaft 22 is integral with the roller carriages, passes through the bracket 14 and is fastened under it by means of the nut 23. A branch pipe 24 is provided for lubricating the bearings,
    The roller carriage 16 has spacing lugs 25 and 26, which are axles for accommodating rotatably supporting rollers 27 on the roller shaft 28 by means of sliding undercuts 29. The axis of the roller shafts 28 are offset relative to the axis 19.
    The upper roller is mounted to prevent the blowing of the blast pipe 1 upwards. The upper roller assembly is located on the bracket 30 attached with screws 31 to the bracket 9, the shelf 32 of the bracket 30 is horizontal.
    The device works as follows.
    When introducing or removing. From the heat exchanger, the blowing pipe, along with forward movement, simultaneously performs rotational movement, III., Pri.-interaction of the support rollers 27 with the blowing pipe 1, the roller carriages 16 due to the displacement of the shaft axes 28 relative to the axes 19, will turn into such position so that the support rollers 27 are perpendicular to the screw lines described by the point of contact of the rollers with the blast tube. In this position, the support rollers prevent them from sliding along the surface of the blast tube, which reduces wear on the blast tube.
    Since the axes of the roller carriages 19 are at an angle to the vertical, the mass of the mixed roller, shaft, and the relative parts of the carriage tend to rotate the carriages in which the axis 19 is horizontal and prevent the rollers from rotating around the axis 19 to the position corresponding to the angle of the helix.
    In order to eliminate the effect of the roller's weight on the action of the niapier, the carriage has counterweights statically balanced with the mass of the roller relative to the axis 19. Such weights of the counterweight are formed by a part of the wall 33 representing the whole and connecting the projectile 25 and 26. Due to the counterbalance effect provided by the areas of the wall 33, the effect of the roller weight does not affect the action of the roller nodes, despite the position of the helix angle of the rollers 27, and since the helix angle changes during operation of the blower, the rollers remain in the floor voltage x, to extend and rotate without sliding friction on the surface of the blow tube.
    The use of the presumed device will increase its reliability by reducing the wear of the blast pipe.
