Description

(54) APPROACH TO DRAINING EXHAUST GASES IN MULTI-SECTIONAL HEAT

one

FIELD OF THE INVENTION The invention relates to a transport engineering industry and concerns the design of a device for exhaust gas removal on locomotives with heat engines.

A device for exhaust gas removal of a multi-section diesel locomotive is known, which contains an exhaust manifold located on each section of the section and communicates with the gas exhaust duct 1.

The drawback of the device lies in the fact that when the two locomotives in the tunnel are paired, the exhaust gases from the front locomotive, reflected from the ceiling of the tunnel, get into the air intake windows and the locomotive driver's cab from behind.

The purpose of the invention is to prevent the ingress of gases into the intake windows of a locomotive when it moves in a tunnel.

The goal is achieved by the fact that the gas exhaust duct is mounted on the roof of the body of a diesel locomotive along its longitudinal axis and is equipped with an exhaust window above the exhaust pipe equipped with pivoting louvers, while the gas exhaust ducts of adjacent sections are connected by a compensating unit for their mutual movement.

In addition, the compensating unit consists of two fixed nozzles rigidly connected to the flanges of the exhaust ducts of the adjacent K sections and a movable nozzle installed inside the fixed on ball bearings and connected to the said flanges by means of clamping bolts and spacer springs.

FIG. 1 shows two sechoc locomotives with a device for exhaust gas exhaust, general view; in fig. 2 - section A-A in FIG. 1 on the compensating unit; in fig. 3 — node 1 in FIG. one; in fig. 4 is a section BB in FIG. 2

Claims (2)

The exhaust gas exhaust device includes a silencer (but shown) with an exhaust pipe 1 and a gas outlet channel 2 located on the body joint. The gas exhaust duct 2 above the exhaust pipe 1 has an exhaust window, closed by pivoting shutters. The louver 3 is rotated by means of a power cylinder 4 located on the side wall of the gas exhaust duct through a system of plugs 5 and levers 6. The duct 2 at the junction with the gas exhaust duct of the other section has a compensating unit consisting of a fixed nozzle 7 rigidly connected with channel 2, the movable nozzle 8 located inside the fixed nozzle 7 on the ball bearings 9. On the inner surface of the lateral walls of the fixed nozzle 7, the sockets 10 with a spherical surface are rigidly attached. Under the movable nozzle 8, on the side walls there are pkhpitsa 11, along which they freely move with two ball joints 9 inserted into its socket in its spherical surface: a 10. The movable and stationary nozzles are connected with two clamping bolts 12 which are welded to the flange 13 the movable nozzle 8, and the other threaded condom freely go into the holes of the flange 14 of the fixed nozzle 7 and the stopper with nuts 15 Between the flanges of the movable and stationary nozzles, there are spacer springs 16 on the attachment boggs 12. va movable nozzle flange 13 is freely one section 8 is connected to the flange 17 of the movable nozzle 8 different sections. The tightness of the fit is ensured by the spacer springs 16. The possibility of fitting the locomotive into the curved sections of the path are both 5 patches by turning the movable nozzle 8 relative to the stationary thanks to a pair of nest 10 bearing 9 having a spherical surface. The free connection of the flanges of the movable nozzles provides the possibility of transverse and vertical displacement of the exhaust ducts 2 of both sections relative to each other. In the normal state, the louver 3 at the exhaust window of the exhaust duct 2 opened, and the exhaust gases passed through the bullet, through the exhaust pipe 1 and the exhaust window was directed vertically upwards. Before the locomotive enters the louver tunnel by means of an air cylinder 4, the systems tg 5 and the levers are closed, and the exhaust gases pass through a damper 4, through the exhaust pipe 1 and the gas exhaust ducts 2 are diverted outside the tiller. The presence of exhaust ducts with a compensating unit for connecting to the exhaust duct of another section allows exhaust gases to escape beyond the locomotive, thereby preventing exhaust gases from entering the intake windows of the locomotive. The working conditions of the crew serving the locomotive are improved, the reliability of the work of electric machines and diesel engines is improved. Formula 1: A device for exhausting a multi-section diesel locomotive, containing an exhaust manifold located on the roof of each section, communicating with a gas exhaust duct, in order to prevent exhaust gases from entering the locomotive intake windows during its movement in the tunnel, the gas exhaust pipe The channel is mounted on the roof of the body of the locomotive along its longitudinal axis and is provided with an exhaust window located above the exhaust pipe, equipped with pivoting shutters, while the exhaust pipes with ezhnyh sections articulated compensating unit which ensures their mutual movement. 2. A device according to claim 1, characterized in that the compensating unit consists of two stationary nozzles rigidly connected to the flanges of the exhaust ducts of adjacent sections and a movable nozzle installed inside the stationary on ball joints and connected to the said flanges by means of clamping bolts and springs.
