Description

The utility model relates to railway transport and relates to devices for opening and closing the covers of unloading hatches of a bunker car.

Known devices for opening and closing the lids of the unloading hatches of the hopper car (EP No. 1078836 B1, B61D 7/26, 06/04/2003; US No. 4606277, B61D 7/26, 08/19/1986; RU No. 564196, B61D 7/16, 12/15/1975 ; RU No. 40620, B61D 7/24, 09/20/2003; RU No. 224649, B61D 7/24, B61D 7/26, 01/20/2005; RU No. 16719, B61D 7/24, 02/10/2001; DE No. 19935577 C2, B61D 7/16, 03/01/2001; GB No. 2081198 A, B61D 7/24, 09/08/1992; SU No. 863444, B61D 7/16, 09/15/1981; SU No. 1650502, B61D 7/26, 05/23/1991; UA No. 62766, B61D 7/16, 12/15/2003). They contain drive shafts kinematically connected with the unloading manhole covers, pneumatic drive and manual drive, as well as drive locking devices in the closed and open positions.

The disadvantages of these devices are the design complexity and the need to seal each manual drive for opening and closing the hoppers, as well as the inability to open the unloading hatches under their own weight.

It is also known a device for opening and closing the covers of the unloading hatches of the hopper car according to the patent SU No. 1640003, B61D 7/26, 04/07/1991, adopted as a prototype. It contains a longitudinal shaft mounted between each pair of hoppers and kinematically connected with the covers of the discharge hatches, the pneumatic drive and the manual drive for unloading control. The manual drive is made in the form of a worm pair placed on the side of the car. The device has a lock for opening and closing the covers of unloading hatches located under the car.

The disadvantages of this solution include the impossibility of accelerating the opening of unloading hatches, the presence of a locking device on each device for opening and closing covers, as well as the need for their separate sealing.

The technical result, which the utility model aims to achieve, is to accelerate the opening of unloading hatches, the introduction of a single locking device and one sealing place.

The technical result is achieved by the fact that in the device for opening and closing the covers of the discharge hatches of the hopper car with one or more pairs of hoppers, in each of which a longitudinal shaft is installed between the hoppers, kinematically connected with the covers of the discharge hatches, a pneumatic drive and a manual drive, while the manual drive is made in the form of a worm pair placed on the side of the car, and a locking device, the shaft of the worm pair is mounted vertically with the possibility of fixation upon disengagement, while on the control side of the manual drive, a longitudinal shaft is installed on the side of the car, equipped with stops, each of which interacts with a locking device mounted on a manual drive, a locking device that restricts shaft rotation and in which holes are made for installing a locking and sealing device, a locking device of each the manual drive contains a rocker fixed by a sleeve mounted on the shaft of the worm pair, at one end of which an eye is fixed with the possibility of entry in the interval between the rotation limiters mounted on the helm mounted on the shaft of the worm pair, and on the other hand is equipped with a handle fixed by a lock.

Leaning and fixing the axis of the worm pair after disengaging is performed at an angle α = 9 ° ... 13 °.

The locking device comprises a bracket mounted on the hopper of the carriage, a slot is made in the vertical transverse wall thereof, and a bracket with a rotary handle is fixed on the longitudinal shaft with the possibility of its entry into the slot and fixing.

The constipation contains an axis with the possibility of rotation, on which the handle is fixed.

In the working position of the worm pair, the beam through the eye is fixed by constipation.

The stops of the longitudinal shaft with a locking device that limits its rotation are located opposite the axes of the locks, fixing the position of the rocker arms.

Constipation, locking the rocker arm in the working and transport positions of the car, are fixed to the housing of the manual drive.

Comparison of the proposed technical solution with the given analogues made it possible to establish the presence of distinctive features, therefore, this technical solution meets the criterion of "novelty."

The device consists of a pneumatic actuator 1 mounted under the wagon, including a pneumatic cylinder 2, connected to the longitudinal shaft 3 using the lever 4 and gears 5, 6. The shaft is installed between each pair of hoppers 7. The levers 8, 9 are fixed to the shaft, connecting them to the covers 10 unloading hatches and a worm pair 11 of the manual drive 12. The control of each manual drive is located on one of the sides of the car. The shaft 13 of each worm pair is mounted vertically with the possibility of fixation when it disengages. Folding and fixing the shaft 13 is made at an angle α = 9 ° ... 13 °. On the side of the car, where the manual drive controls are located, a longitudinal shaft 14 is installed, equipped with stops 15. Each stop interacts with a locking device 16 mounted on a manual drive. A fixing device 17 is mounted on the same shaft, which restricts the rotation of the shaft. It contains a bracket 18 fixed to the shaft with a pivoting arm 19 cooperating with a vertical transverse wall 20 of the bracket 21, mounted on the hopper 7 of the car. A slot 22 is made in the wall 20 for inserting and fixing the pivoting arm 19. A cap 23 is attached to the wall, fixing the handle 19 in the slot 22. In the cap and the wall there are holes through which a locking and sealing device 24 is installed. A longitudinal shaft passes through the hole in the wall 14, which is its additional support.

The locking device 16 of the manual drive contains a beam 25 mounted on the shaft 13 of the worm pair and fixed on top by a sleeve 26 with two axles 27. An eye 28 is provided at one end of the beam, which extends between the stops 29 mounted on the helm 30 mounted on the shaft 13 worm pair. In the operating position of the manual drive, the beam 25 through the eye is fixed by a lock 31, mounted on the housing 32 of the worm pair. The other end of the rocker arm 25 is provided with a handle 33 with a hole 34. Opposite the hole is the axis 35 of the lock 36, fixing the handle. The stroke of the axis from its other end limits the stop 15 of the shaft 14. The locks 31, 36 are fixed to the housing 32 of the manual drive. Their axis 37, 35 are equipped with handles 38 and 39, respectively.

Manual drive operates as follows.

In the transport position, to prevent accidental or unauthorized opening of the covers 10 of the unloading hatches, the longitudinal shaft 14 is fixed with a buckle 23, which fixes the rotary handle 19 in the slot 22 of the wall 20 and prevents the shaft 14 from turning. at the same time, the end of the axis 35, brought into the hole 34, fixes the handle 33 of the rocker arm 25, ensuring that the eye 28 is located between the stops 29, which blocks the rotation of the helm 30 and the opening of the unloading lids Cove.

To bring the unloading mechanism into working position, it is necessary to unlock the manual drives. The locking and sealing device 24 is removed from the locking device 17 of the longitudinal shaft 14, the handle 19 is removed from the slot 22 of the wall 20, providing a rotation of the shaft 14 with the stops 15 fixed on it. The rotation of the shaft provides the removal of the axis 35 of the lock 36 from the hole 34 of the arm 33 of the rocker arm 25, after which the end of the rocker arm with the eye 28 lowers down, freeing the steering wheel 30 from the locking eye, and is fixed by the axis 37 of the lock 31 by introducing it into the hole of the eye. The shaft 13 of the worm pair is engaged by setting it in a vertical position until it engages with the wheel 40. By rotating the steering wheel clockwise, create a torque on the longitudinal shaft 3, which opens the covers 10 of the unloading hatches through a system of levers. In this case, after the levers 41 pass through the “dead center” and the shaft 13 of the worm pair is tilted to an angle α = 9 ° ... 13 °, the opening of the unloading manhole covers is accelerated.

After the wagon is unloaded, turn the helm counterclockwise to close the covers of the unloading hatches. After their closure, the shafts of 13 worm pairs remain in an engaged state.

The use of a pneumatic actuator for opening and closing the covers of unloading hatches consists in supplying compressed air to the pneumatic cylinder 2 under the piston 42 or to the piston, which is kinematically connected with the covers of the unloading hatches of each hopper. In this case, the forces from the piston 42 connected to the lever 4 are transmitted through the gears 5, 6 to the shaft 3 connected to the covers 10 of the unloading hatches.

The claimed solution allows to accelerate the opening of the covers of unloading hatches, to reduce the time of unloading. In addition, the vertical installation of the shaft 13 in the engaged state with the possibility of fixing the position of the steering wheel 30 with the eye 28 and the lock 36 of the locking device 16 eliminates the possibility of opening the covers 10 of the unloading hatches under their own weight.

The solution also provides a single locking of all manual drives in one place and the installation of only one locking and sealing device. At the same time, a triple blocking of the opening of the covers is provided, preventing their accidental or unauthorized opening:

- in the place of fixation of the handle 33 of the rocker arm 25, fixed by the axis 35 of the constipation 36 and the stop 15,

- the other end of the beam with an eye 28 located between the limiters 29 of the helm of the worm pair,

- a locking device 17 that prevents rotation of the shaft 14.

In addition, the hand drive uses a worm pair of the car’s parking brake, which reduces the range of parts and increases the level of product unification.

At present, after successful testing of a car with the proposed device, it is undergoing serial production.
