Abstract

The invention relates to transport construction and can be used in the erection of a landbed of railways and roads on weak soils, as well as in other cases when it is impossible to move dump trucks near an embankment. The purpose of the invention is to reduce transport operating costs, improve work safety and improve the working conditions of the driver at the dumping of narrow profile embankments at. increasing the intensification of work. When dumping narrow-profile embankments on an embankment in the place of a turn of the car, a mobile overpass with a platform located on it is installed. The width of the platform take more than the width of the dumped mound. Move the car to the platform, turn it around and move it to the place of unloading. After that, it is unloaded and moved to the place of reloading. The overpass is moved as dumping embankment follows the movement of the work front. The mobile overpass contains a running gear, a ramp with a platform installed at both ends and a stop installed on the side of the platform that extends beyond the embankment. 2 sec. and 1 z. p. f-ly. 5 il. cl

Description

The invention relates to transport construction and can be used in the construction of the earth bed of railways and roads on weak soils, as well as in other cases when it is impossible to move the dump trucks next to the embankment (buildings, structures, power lines, etc.).

There is a known method of erecting a roadbed by a carriage on weak soils, including loading the dump truck with soil, transporting it along the finished section.

embankment, 180 ° reversal and backward movement to the place of unloading.

The disadvantage of this method is the necessity of turning the loaded dump truck under difficult conditions — on a narrow embankment, which requires increased fuel costs, unnecessarily tires the driver and multiplies the consumption of a vehicle.

As a result, the productivity of the dump truck fleet decreases, the cost of building the earth bed increases.

The purpose of the invention is to reduce transport operating costs, increase work safety and improve the working conditions of the driver on dumping of narrow profile embankments, while increasing the intensification of work.

The goal is achieved by the fact that in the method of construction of the embankment on weak soils, including installation of the platform, moving equipment on it, moving the platform, filling the embankment, transporting the soil along the embankment, turning the car and moving it to the place of unloading, on the embankment in the place of turning the car set The platform with a platform located on it, the width of which receives more than the width of the embankment, the car is moved onto it, and the rack is moved as the embankment is dumped following the movement iem front work.

From practice, it is known to use trailers to move vehicles.

However, the trailer does not provide the possibility of turning the vehicle on it. In this method and devices, a mobile platform is proposed for its implementation, which allows the vehicle located on it to turn, which allows to solve the technical problem of facilitating the turn of the dump truck when dumping the roadbed on weak soils and on this basis achieve the goal.

Fig. 1.2 shows the implementation of the method using a platform mounted on rolling bodies in the form of wheels, for example, on the basis of a 60 tonne trailer; 3-5, the method is implemented using a turntable mounted on rollers.

The method for erecting the earth bed is as follows. The dump truck moves along the embankment to point a, from which it begins its entry into the mobile overpass and turn along the AB trajectory. Then the dump truck is reversing along the overpass along the path b-in, after which it moves forward along the path of -d and backwards along the path of the G-d slides off the overpass and moves to the place of unloading. As the discharge front moves forward, the distance increases. When it reaches L B m, the overpass is moved along the construction of the earth bed by 30–40 m. Then the cycle repeats.

Another embodiment of the method is depicted in FIGS. 3-4, where the dump truck is turning using a swiveling eccade.

The proposed method provides a large economic effect. Using the proposed method

roughly doubles the turn. The mobile overpass (Fig. 1) consists of platform 1 and ramps 2. Platform 1 is mounted on rolling bodies to move along the embankment. Figure 2 shows a variant in which wheels 3 are used as rolling bodies. Platform 1 with wheels 3 can be made on the basis of a trailer with a carrying capacity of 60 tons. The overpass can be equipped with backwash 5 with support 5 (shown by dashed lines).

The overpass 1 in the rotary version can be mounted on tracked trolleys 6 and have, for example, a gear

0 drive 7, which receives movement from the engine 8, which is connected, for example, by a chain gear 9 with a gear drive 7 and combined with the operator's cab. A device for implementing the method works as follows. The dump truck, moving forward towards the dumping site, drives along ramp 2 onto platform 1 and maneuvers on it abvgd, retracting backward in the direction of the place of unloading, then moving straight ahead to the place of loading, moving through overpass 1 in the opposite direction. C. With the help of wheels 3, the overpass can be moved with a bulldozer, leveling the soil, to the required distance along the canvas. When using a turntable, a dump truck on ramps 2 enters platform 1 and stops on it. The operator connects with the help of a clutch a motor 8 with a chain transmission 9, which rotates the rotation mechanism 7, as a result of which the platform 1 rotates 180 ° and stops. Then, in reverse, the truck moves down along ramps 2 in the direction of the unloading site, after which the truck returns to the place of loading, passing next to the overpass.

The described devices for carrying out the method are very simple and do not require large costs for manufacturing.
