Definitions

  • the invention relates to a device for hopper dispensers for dosing ballast on a railway track during its construction, repairs and current maintenance and can also be used in the construction of track machines and hopper cars.
  • a bunker car including a ballast dosed discharge device mounted on the carriage frame, consisting of a hopper with unloading hatches, overlapping covers having a drive shaft connected by rods and levers with pneumatic cylinders (SU 1309999 Al, B61D 7/26, 05/15/1987 .).
  • Known track machine containing a device for adding ballast mounted on the frame, and consisting of a tank with holes in the lower part, overlapping covers mounted on shafts (RU 2196860 Cl).
  • the disadvantage of these devices is the design complexity, including due to the fact that each technological function of the hopper dispenser (unloading, batching, backfill restriction, etc.) has its own device, while the hopper dispenser has more than one drive, in particular one, including articulated linkages and power cylinders, for a discharge device, and the other for a metering device.
  • the disadvantage of this device is the lack of separate unloading of ballast from different hatches, limiting the number of discharge openings, no more than two, as well as their limited location on the hopper (above the rails).
  • the design of the dispenser is a connection of lateral, transverse and nadrelsnyh beams, which is attached to the frame and rises along the rails at different heights from the rail head, and when the ballast is distributed along the railway track, the guides are skewed, which is invisible when the dispenser is working, but the vertical plane passing through the axis of symmetry of the rails and the vertical plane, passing through the axis of symmetry of the discharge opening will not coincide, which will lead to incomplete overlapping of the discharge hatch with overhead rails of the dispenser.
  • the dispenser is not used at all
  • the technical result of the invention is to increase the versatility of the hopper dispenser, simplify the design and increase the reliability of the device, its maintainability, ensure during operation of the device on the hopper car or track machine the free opening and closing of the openings of unloading hatches, the number of which is unlimited and their location on the hopper is arbitrary.
  • a hopper dispenser car having a hopper resting on the car frame with unloading openings in the form of unloading hatches, overlapped by covers made in the form of a curved profile, and most effective if it is a corner profile with its top up and a ballast dispenser, having the drive mounted on the frame and providing a rise of the dispenser in height, is made in such a way that each cover is mounted with the ability to move it in a vertical plane and is connected with the drive movement, which limits the lowering of its lower plane below the lower plane of the dispenser in its working position, and the length of each cover is less than the length of the dispenser on the inside of the dispenser and more than the length of the discharge hatch.
  • the discharge opening of the hopper is aligned with a vertical plane passing through the longitudinal axis of symmetry of the lid, while the width of the base of the lid is not less than the width of the discharge opening of the hopper.
  • the unloading hatches are placed above the rails, and the lid in this case is an over-railing beam that prevents ballast from falling onto the rails.
  • the top of the corner of the lid for technological reasons can be cut off, and the lid can be a single curved screen or consist of a profile on which a corner is shorter than the profile that is the base of the lid.
  • the angle “cc” under which the shelves of the corner profile of the lid and the angle “ ⁇ ” formed by the walls of the hopper are connected is expediently made equal.
  • this angle is straight and then the width of the profile shelf is easy to calculate with respect to the width of the opening of the discharge hatch according to the Pythagorean theorem, provided that the width of the base of the triangle should not be less than the width of the discharge opening of the hopper.
  • ballast dividers made, for example, in the form of pylons or pins mounted in the top cover.
  • the pneumatic or hydraulic actuator cylinders through a system of rods and levers are fixed at one end to the frame or hopper of the vehicle and the other to the lid beam.
  • the power cylinders can be located under the cover, for example, so that the piston enters contact with the cover, and the cylinder is attached to the frame or hopper using brackets.
  • the drive ensures that the lid is raised to a height that allows the lid to rise until the surface of the lid shields comes into contact with the edges of the hopper manhole opening and overlaps this opening.
  • the cover can be fixed on the axis, so that it can not only be lifted vertically upwards, for example, at the ends of the axis, but also rotated and fixed relative to the axis by a predetermined angle, redistributing the ballast inside and outside the rail track.
  • One of the constructive solutions of the rotation of the cover relative to the axis is the placement of the actuator power cylinders on different sides of the axis of symmetry of the beam with their separate switching on and off.
  • the simplest cover drive is mechanical, for example, a helical or worm gear.
  • the drive rails are located in the same vertical plane as the plane passing through the longitudinal axis of symmetry of the discharge opening and the longitudinal axis of symmetry of the cover, which in a particular case passes through the top of the corner profile.
  • Such a constructive solution of the drive does not require its connection to the air line, which allows to expand the scope of application of the hopper dispenser.
  • Fig. 1 shows a diagram of a hopper dispenser for unloading and dispensing bulk goods with two openings in the hopper, overlapped by lids formed by a corner profile with the top up, one lid is raised and covers the opening of the discharge opening, and the second is lowered so that the discharge opening is free for unloading ballast.
  • the cover drive can be mechanical with guide rods or have power cylinders through a system of rods and levers connected to the cover.
  • the hopper-dispenser is a hopper 1, supported by a frame 2, a cover 3, located under the openings of the discharge hatches 4 with the possibility of movement in a vertical plane passing through the axis of symmetry of the hole in the hopper.
  • the cover 3 has a drive consisting of one or more power cylinders or mechanical gears (for example, screw, worm) 5 with guides 6 and levers or brackets 7.
  • each cover may have its own drive, and may have a drive combined with the drive of the other cover.
  • the length of the ballast dispenser 8 is greater than the length of the cover 3. In order for the cover in the working position not to fall below the lower surface of the dispenser 8 in its working position, stops can be installed on the dispenser at a predetermined height. The lowering height of the cover can also be adjusted using the drive, limiting its progress.
  • the width of the base 9 of the lid 3 is not less than the width of the discharge opening 4.
  • a baffle plate 10 can be attached to the cover 3, for example, in the form of a corner, and on the edges of the discharge opening 4 of the hopper 1 gaskets can be placed, for example, in the form of rubber petals.
  • the length of the lid 3 is greater than the length of the discharge opening 4 of the hopper, in order for the lid to enter the opening of the discharge hatch, cutouts are made in the end walls of the hopper to ensure its installation.
  • the lid can be made of a corner profile, which is attached to a plate, beam or other curved profile, while the length of the corner profile is no more than the length of the discharge hatch. In this case, cutouts in the end walls of the hopper are not made.
  • the device operates as follows.
  • the lid 3 along the guides 6 rises to a height until the edges of the lid 3 and the edges of the hole 4 of the discharge door of the hopper 1 touch. In this case, the hole 4 is closed and the ballast does not expire.
  • the baffle plate 10 is placed on the outer surface of the lid 3 at such a distance that when the hole 4 of the hopper 1 is closed lid 3, the distance b from the edge of the hole of the hopper to the baffle plate 10 was not more than the average size of the fraction of transported ballast.
  • gaskets can also be installed on the hopper in the area of the discharge opening.
  • the limitation of lowering the cover is not lower than the lower surface of the dispenser only when the dispenser is in operation, when it is in the working position. In the inoperative position of the dispenser, as well as in the case when there is a need for quick unloading of ballast residues from the hopper, and the ballast dispenser is, for example, in the transport position, it is allowed to lower the cover below the lower surface of the dispenser. Therefore, if stops are installed as a limitation of the lowering of the cover, they should be made with the possibility of their removal or adjustment.
  • This method of ballast unloading allows it to be unloaded with the possibility of interruption, while significantly simplifying the design of the hopper batcher, allowing the proposed construction of the hopper batcher to be used not only on vehicles (cars, track machines), but also stationary.
