Description

Semi-trailers for transporting long circular products are known, comprising a frame carrying load bearing cushions and retractable rolls for loading and unloading over the conveyed products using a troso-block system driven by a winch.

The purpose of the invention is to accelerate the resetting of the troso-block system for loading and unloading products, ensuring their safety from damage. To do this, the troso-block system includes a frame mounted on the frame underneath the supporting side blocks, with two blocks arranged one above the other, changing the direction of movement of the load through the supporting blocks; retractable rolls are provided with interchangeable profile guides to change the angle of the load movement when rolling it from the support cushions to the rolls or in the opposite direction.

FIG. 1 schematically shows a semi-trailer, side view; in fig. 2 - the same, end view; in fig. 3 - troso-block system; in fig. 4 shows the node A in FIG. one; in fig. 5 - cut but. BB in FIG. four; in fig. 6 shows schematically the loading operation of the products; in fig. 7 - unloading scheme.

part of the frame is mounted on the saddle device t gacha, which is equipped with an automobile winch 3. The winch is mounted behind the cab on the frame t gacha and is driven from the gearbox. When off-road, a tractor tractor with a sliding cart from a standard trailer with a mounted saddle can be used.

The frame of the trailer is equipped with support cushions 4 for long products (see FIG. 2) with sockets cut into them and wrapped in elastic material from above. To hold the load on the frame in the transport position

but its sides have removable racks 5. A shield is installed in front of the frame to prevent further displacement of cargo, and a boardwalk is made on the frame for transporting other goods.

Long products of circular cross section are loaded onto semi-trailer outrigger outriders 6, which are extended from the cross member of the frame and are equipped with supporting reinforcements 7. Smooth movement of the load along the slopes is provided by a troso-block system including two cable 8 fixed to the winch (see Fig. 3 ), envelopes located on the frame blocks 9-14. The free ends of the cables when loading the parts secured to the load - on the brackets / 7 with the help of fingers 18.

In order to change the direction of the injector ii) y, during retrofitting, they were redeemed for loading or unloading products into the system, which was mounted on the frame under the supporting lateral blocks of the holder system 19 with two located one above the other blocks 14, in between commissioning a troso-blochoy system for unloading products from a semi-trailer, a cable is laid.

The rides are equipped with a mixture of profile packages 20 for loading and 21 for unloading, providing an unaccented transfer of cargo from the slopes of the pa supporting legs and back.

The loading and unloading of long-gauge reinforced round-shaped products is carried out in the following order.

When loading, the slides are advanced, which are set with boots on the ground and secured with fingers on the frame. Then, from the loading side, the safety pillars 5 are removed, and the profile packs are installed on the rails in their connection with the frame, after which they turn on the winch, the drum of which turns the cables of the required length, chosen by the rigging tools through the loading blocks, and turns off the power take-off.

Then, cables are covered from top to bottom in the front and rear parts of the product, the cables under the product are pulled and the free ends are secured with brackets 15 by brackets 16 using fingers / 8. After that, the power take-off is turned on, cables begin to be wound on a drum winder, which roll the product along the slopes of the frame until it is in its intended slots on the supporting frame. Then my 1pc selection box, 1m, is switched on & t, and the cables loose. Operations Ivtor yuchs to iolnaya boot semitrailer.

The unloading operation is similar to the loading operation, but the plates 21 are installed on the ramps, and the cables are inserted into the gap between the blocks 14 of the yoke 19 through the side blocks 13. In this case, the cables also cover the product from the top and secure with the free ends of the brackets 17. Then the box power take-off, and the winch when winding the cable reel rolls the product onto the edges of the support pads and slopes. At this moment, the winch drum is retracted, and the weight of the glide rolls down the slopes. The process is then repeated until the semi-trailer unloads it.

P re d m o te p z obretep p

Semi-trailer mainly for transportation of long reinforced concrete products of circular cross section, containing - a three-dimensional frame, carrying support / dears for laying cargo on them and retractable ramps for loading and unloading over them of transported products by means of a troso-block system with a drive from a winch t gacha, characterized in that, in order to speed up the irealadka of the troso-block system, both for loading and unloading products with the preservation of cargo from damage, the mounted system and a frame under the supporting side blocks of the system is a block holder with two blocks located one pad and measuring the movement of the load through the supporting blocks, and the ramps are equipped with interchangeable profile guides to change the angle of the load path when rolling it from the support cushions of the rolls and in the opposite direction direction.
