SK8212Y1 - The mechanism for raising the come out flap of the wagons for car transportation - Google Patents

Abstract

The mechanism for raising the come out flap (4) of the wagons for car transportation comprises at least two straightforward mechanisms (1) which are connected to the input shaft (5). The linear straightforward mechanisms (1) are connected with strips to the roller pulleys (2). Strips (2) with the drive pulleys are pivotally connected to the lever assemblies (3). The lever assemblies (3) are fastened to the ramp (4). Rotating the input shaft (5) strips (2) with the drive pulleys are pushes or pulls, thereby changing the inclination of the lever array (3) and thereby changing the height of the come out flap (4).

Description

Technical field

The technical solution relates to a mechanism for lifting the access flaps of railway wagons for the transport of cars, which enables loading and unloading of cars with low ground clearance without the risk of collision of the chassis and overhangs of cars with parts of the wagon platform.

BACKGROUND OF THE INVENTION

A well-known solution is to lift the access flaps of railway freight wagons transporting cars by means of a mechanism consisting of four screw lifts located under the access flap and driven by a system of seven transmissions

GB995136 A published 1965-06-16 discloses a rail wagon with a frame which is designed as a wagon platform. At one end of the frame, a movable platform is mounted with coupling means for connecting the wagon to another wagon, the platform being rotatably mounted at the end of the frame in such a way that the platform is movable between an upper position and a lower position under the floor of the wagon. Its arrangement is such that in the lower position the coupling means is parallel to a horizontal or substantially horizontal plane.

FR2473974 A1 published 1981-07-24 discloses a wagon having movable platforms for manually manipulating the positioning lugs for attaching the wagon end. The platforms protrude above the buffers to connect the platform at the end of the wagon or other end freight wagon. The platforms are located slightly higher than the floor of the wagon and near the floor of the container. The platform is mounted in a suspension bracket at the end of the wagon.

EP0518750 A1 published 1992-12-16 discloses a wagon having an end ramp that is coupled to a bumper and articulated about a transverse horizontal axis, the ramp being equipped with rails for loading or unloading bogies. The ramp is raised or lowered by a motor pump with a hydraulic control system and a reversible motor that passes through a chain and gear. The hydraulic system may include rollers that raise and lower the ramp.

DE2447576 A1 published 1976-04-08 discloses a wagon having a loading platform for freight wagons. The support platform is situated between two adjacent freight wagons which are standing one behind the other and which are provided on their underside with support bearings which are mounted above the buffer bearings or have bearing sleeves which extend through the alignment sleeve itself. This equipment provides a rigid attachment of the loading platform between two adjacent trucks so that it is possible to drive during loading or unloading operations. The bearing bearings have guide plates at those ends facing the underside of the loading platform that engage sliding guide elements attached to the platform.

US2003110975 A1 published 2003-06-19 discloses a wagon having a loading platform wherein a ramp control mechanism for a rail vehicle has a first cylinder, a second cylinder and a clutch to move to a raised position. The first double-acting cylinder causes the second double-acting cylinder to move the arm and coupler to the lowered position when the first cylinder moves the ramp to the open position. The first roller causes the second roller to move the arm and the lifting device to move it to the raised position when the first roller moves the ramp to the stored position. The device is used to load and unload cargo, e.g. semi-trailer from the train. The mechanism reduces ramp impacts. Reduces the operating pressure required to raise and lower the ramp, reducing compressed air consumption per operating cycle.

All the prior art solutions described contain a number of drawbacks, in particular the complicated construction and use of complicated components, or solutions that are not manageable and must be manually placed in the desired location.

The essence of the technical solution

The drawbacks of the prior art are overcome by the utility model described in the present application, which is based on a mechanism for raising the access flaps of a car wagon which comprises two linear drives and lever assemblies with rails equipped with rollers. Linear drives, when rotating the input shaft, push the rails with the traveling pulleys, thereby causing the lever assembly to change its position and thereby causing the access flap, which is associated with the lever assembly, to consist of straightforward mechanisms associated with the traveling pulley rails. On the rails there are pivotally mounted lever assemblies which support the access flap.

By rotating the input shaft, the rails with the traveling pulleys are pushed or pulled, thereby changing the inclination of the lever assembly and thus the height of the access flap.

The advantage of this mechanism is the use of two linear drives instead of four thread lifts and seven transmissions.

Fig. 2 and 3 show the approach flap in the lower and upper positions (without the vehicle body).

An exemplary embodiment

The drive flap lifting mechanism 4 of the carriage includes at least two linear mechanisms 1 which are connected to the input shaft 5. The linear mechanisms 1 are connected to the rails 2 with the rollers.

The rollers 2 with the rollers are rotatably connected to the lever assemblies 3. The lever assemblies 3 are mounted on the access flap 4. The linear mechanisms 1, when rotating the input shaft 5, push the rollers 2 with the rollers, thereby causing the lever assembly 3 to move. to raise the access flap 4, which is connected to the lever assembly 3.

By rotating the input shaft 5, the rails 2 with the rollers are pushed or pulled, thereby changing the inclination of the lever assembly 3 and thereby changing the height of the access flap 4.

Industrial usability

The flap lifting mechanism is suitable for freight wagons for the transport of cars, which allows loading and unloading of cars with low ground clearance without risk of collision of the chassis and overhangs of cars with parts of the wagon platform. The mechanism consisting of a small number of parts is also suitable for wagons which have limited space to accommodate the mechanisms for controlling the access flap.
