RU44294U1 - HOPPER WAGON FOR CARRIAGE OF BULK CARGOES - Google Patents

Abstract

The utility model relates to railway transport, namely, to the design of hopper cars designed for the transportation of bulk cargo. The essence of the utility model lies in the fact that the inventive hopper car is equipped with slide-type unloading devices, self-sealing by raising the slide gate at the end of its movement to close the hopper discharge hatch until it is pressed firmly against the seal, the rack drive shaft of which is mounted on the suspension guides of the slide gate, and the seal is made in the form of a closed hollow cylinder with the possibility of supplying compressed air from the air line of the hopper car itself.

Description

The utility model relates to railway transport, namely, to the design of hopper cars designed for the transportation of bulk cargo.

Known hopper wagon for transporting grain (utility model certificate RU No. 17496 U1 7 B 61 D 17/00 of April 10, 2001 of the Russian Federation), containing a running gear in the form of two biaxial trolleys with a covered body, the frame of which includes a spinal and king pin beams. Body components are side walls, end inclined walls, a roof with loading slotted hatches and discharge hatches with discharge mechanisms placed on the bunkers.

In a cross-section, the body is made in a rectangular shape with a roof in the form of a half-cylinder, and the side walls are extended lower to the transition to the bunkers. On the latter, devices for mounting vibrators are fixed on the outside.

Each unloading hatch is closed by a rotary lid, the drive of which is a screw pair (unloading mechanism).

The hopper wagon is loaded through open loading slotted hatches, and unloading through loading hatches with unloading mechanisms using vibrators with open loading hatches.

The main disadvantages of the analogue include:

- insufficient tightness of the closed discharge hatch leads to atmospheric moisture entering the transported cargo;

- the presence of spills of transported goods;

- the use of vibrators during unloading.

The prototype of the utility model is a hopper car for transportation of bulk cargo (utility model patent No. 34478 of December 10, 2003 of the Russian Federation), containing a body equipped with loading hatches on the roof and unloading on the bottom of the bunkers mounted below the power frame, equipped

reinforced cantilever parts and elements of the spine beam to the level of pivot beams, rigidly connected by a side strapping and T-beam cross beams placed in the planes for installing the separation walls of the body compartments, mounted on biaxial carts, the body in the lower part of the drop-shaped form, and the upper part is made rectangular in shape with inclined sections from the longitudinal axis, rigidly connected to the frame, and slide-type discharge devices (discharge hatches).

The body consists of side walls, end walls, reinforced with ribs and uprights, which at the same time are the access ladder to the roof with loading hatches, power flooring, lightweight separation walls and forming bunkers together with side and end walls.

T-bar cross beams are installed in the plane of the separation walls. Access inside the body to the power flooring is provided by the ladder.

The cantilever parts of the frame between themselves and the side walls are connected by welding with angular profiles.

The sliding gate device, bolted to the hopper discharge hatch, contains a frame on which a slide gate is installed that moves along the guides of the frame and equipped with a rack gear, sealing the gate valve along the contour of the discharge hatch, a shaft mounted on the frame with rack gear sprockets and tips rotation of the shaft, hinged limiter of the slide gate movement.

The main disadvantages of the prototype include:

- the presence of spills of transported goods;

- rapid wear of the slide seal (abrasion) during operation of this discharge device;

- hit of atmospheric moisture on the transported cargo through unloading devices.

The purpose of the utility model is to create a hopper car for transportation of bulk cargo, equipped with a discharge gate device, eliminating the presence of spills, wear of the gate seal and atmospheric moisture on the transported cargo.

The essence of the utility model lies in the fact that the inventive hopper car is equipped with a slide unloading device, self-sealing by lifting the slide gate at the end of its movement to close the hopper unloading hatch until it is pressed firmly against the seal, the rack and pinion drive shaft of which is mounted on the suspension guides of the slide gate, and the seal is made in the form of a closed hollow cylinder with the possibility of supplying compressed air from the air line of the hopper car itself.

The essence of the utility model is illustrated by drawings, where:

figure 1 shows a General view of a hopper car for transportation of bulk cargo;

figure 2 - remote element A (front view of the slide gate unloading device);

figure 3 is a section bB (cross section of a slide-type discharge device);

figure 4 is a cross-section bb (view in plan of the slide gate unloading device).

The hopper car for transportation of bulk cargo 1 (Fig. 1) contains a frame 2, equipped with reinforced parts with elements of the spine beam and pivot beams 3 with ferns 4, mounted on biaxial trolleys 5, body 6, rigidly connected to frame 2, and self-sealing sliding unloading devices 7 (unloading hatches).

The body 6 in the lower part is teardrop-shaped, and the upper part is rectangular in shape with inclined sections from the longitudinal axis, consists of side walls 8, end walls 9, reinforced with ribs 10 and struts 11, which are simultaneously an access ladder to the roof 12 with unloading hatches 13, power flooring 14, lightweight separation walls 15 and forming hoppers 16 together with side walls 8 and end walls 9. T-bar cross beams 17 of frame 2 are installed in the plane of the separation walls 15. Access inside the body 6 to the power flooring 14 is provided along the ladder 18.

The cantilever parts of the frame 2 between themselves and the side walls 8 are connected by welding with angular profiles 19.

The gate unloading device 7 comprises a housing 20 (FIG. 2), bolted to the hopper 16, with pins 21 for installing suspensions 22, a stop 23 and labyrinths 24 to prevent atmospheric precipitation from entering the gate gate 25 with a stop 26, rigidly connected to the rails 27, moving along the suspension rail 28, equipped with pins 29 mounting suspensions 22.

At the lower end made with radial angles of the housing 20, a seal 30 is installed in the form of a closed hollow cylinder.

On the hanging guide 28, a shaft 31 (Fig. 4) of a rack and pinion drive with sprockets 32 and tips 33 and a tilt stop 34 is mounted.

Closing with the shutter slide 25 of the unloading hatch of the hopper is carried out by lifting it at the end of the movement to close until it is firmly pressed against the seal. Rotating the shaft 31 to the right with the lever (crowbar) for the hole in the tip 33, while the sprockets 32, running around the rails 27, move the slide gate 25 to the left until the stop 26 contacts the housing 20. When the shaft 31 rotates further, the suspension moves

guide 28 to the right, while turning the suspensions 22 around the pins 21, the suspension guide 28 is simultaneously lifted up together with the slide gate 25 until it stops against the seal 30, thereby achieving a tight seal of the slide gate 25 and the latter is prevented from sliding over the seal.

The suspension guide 28 is fixed in the extreme right position (with the stop of the slide gate 25 against the seal 30) by the hinged stop 34.

The opening of the slide gate 25 is performed in the reverse order, while limiting the movement of the suspension guide 28 to the left is provided by returning the suspension 22 to the stop 23.

The loading of the hopper car is carried out through the loading hatches 13 with the shutter gate 25 closed, and unloading with the open loading hatches 13 and the gate shutter 25 into the rail space.

The technical result achieved by the utility model is the absence of spills of the transported cargo, wear of the valve seal (its abrasion); elimination of atmospheric precipitation on the transported cargo through unloading devices.
