(54) ТРАНСПОРТНОЕ СРЕДСТВО ДЛЯ ПЕРЕВОЗКИ ДЛИННОМЕРНЫХ ГРУЗОВ(54) VEHICLE FOR CARRIAGE OF LONG-DIMENSIONAL GOODS

Изобретение относитс к транспортным средствам дл перевозки длинно1 герных грузов и может быть использовано, в частности, при перевозке крупногабаритных строительных конструкций .The invention relates to vehicles for the transport of long goods and can be used, in particular, for the transport of large building structures.

Известны полуприцепы дл перевозки длинномерных железобетонных изделий, содержащие раму, опирающуюс передним концом на опорно-сцепное устройство т гача, а задним - на колесную тележку и снабженную подвесной кареткой, перемещающейс по полкам лонжеронов рамы 1.Semi-trailers for transporting long-length reinforced concrete products are known, which contain a frame supported by a front end on a coupling hitch and a rear one on a wheeled cart and fitted with a suspension carriage moving along the flanks of the frame side members 1.

Использование таких полуприцепов дл перевозки длинномерных строительных конструкций не обеспечивает надежности транспортиров ки изделий в части соблюдени их сохранности .The use of such semi-trailers for the transportation of lengthy building structures does not ensure the reliability of transportation of products in terms of compliance with their safety.

Наиболее близким техническим решением вл етс транспортное средство, содержащее балансирные тележки, несущие раму с обводными блоками, втулки, жестко присоединенные к раме, стойки, установленные во втулках с возможностью вертикального перемещени , в нижней части которых закреплены блоки, пара канатов, огибающих обводные блоки и блоки,закрепленные на стойках, и седловины 2.The closest technical solution is a vehicle containing balancing trolleys carrying a frame with bypass blocks, bushings rigidly attached to the frame, struts mounted in the bushings with the possibility of vertical movement, in the lower part of which there are blocks, a pair of ropes, enveloping bypass blocks and blocks mounted on racks and saddles 2.

При использовании известного транспортного средства дл перевозки длинномерных грузов изделие опираетс на подвижные стойки, имеющие по концам блоки и св занные между собой канатом, что не позвол ет должным образом снизить нагруженность перевозимых строительных конструкций. Кроме того, такое устройство не обеспечивает, устойчивого положени крупногабаритного груза в транспортном- положении.When using a known vehicle for the transport of long goods, the product rests on movable racks having blocks at the ends and interconnected by a rope, which does not allow for a proper reduction of the load on the transported building structures. In addition, this device does not provide a stable position of a large-sized cargo in the transport position.

Дл снижени нагруженности перевозимого груза при.,перевозках транспортное средство снабжено второй парой канатов, огибающих обводные блоки и блоки,закрепленные на стойках , рама состоит из арки с кронштейнами на концах, и седловины закреплены в верхней части стоек, при этом между седловинами и втулками установлены, пружины, канаты одними концами присоединены к кронщтейну рамы, а другими - к оси балансирной тележки.Дл обеспечени устойчивости груза в транспортном положении кажда пара канатов запасована через разные блоки, закрепленные в нижней части стоек.In order to reduce the load of the transported cargo during transport, the vehicle is equipped with a second pair of ropes, envelopes bypass blocks and blocks fixed to the uprights, the frame consists of an arch with brackets at the ends, and the saddles are fixed in the upper part of the uprights, while between the saddles and bushings are installed , springs, ropes at one end are attached to the frame bracket, and others to the axis of the balance trolley. To ensure the stability of the cargo in the transport position, each pair of ropes is stored through different blocks fixed s at the bottom of the racks.

На фиг. 1 дана схема транспортного средства; на фиг. 2 показана запасовка одного из канатов.FIG. 1 given the scheme of the vehicle; in fig. 2 shows the reserve of one of the ropes.

Claims

balance trolleys 2, movable racks 3-6, on the lower ends of which blocks 7 and 8 are installed, and on the upper ones - cargo saddles 9 and 10, ropes 11 and 12, which at one end are attached to the bracket 13 of frame 1, and the second through bypass blocks 14 to the axis 15 of the balancing trolley 2, bypass blocks 16, 17, 18, 19, supporting ropes I and 12, springs 20 and 21 installed between the saddle 9 and the sleeve 22 of the frame 1 and the saddle 10 and the slider 23 of the frame 1. The rope 11 bends around blocks 7 racks 3 and 4 and bypass blocks 14, 16 and 17 (see Fig. 2), and rope 12 - blocks 8 racks 5 and 6 and bypass blocks 14, 18 and 19. Thus, the group From 24, the building structure rests on the cargo saddles 9 and 10 of the uprights 3-6, while the springs 20 and 21 compensate for the difference in deflections of the ropes 11 and 12 under the uprights 3 and 4 and the uprights 5 and 6, additionally engaging the frame 1 in operation. the spring stiffness is chosen equal to the differences between the elastic stiffnesses of the uprights 3 and 4 on the rope 11 and between the elastic stiffnesses of the uprights 5 and 6 on the rope 12. In motion, when the load 24 oscillates, additional straightening of the frame 1 causes additional tension on the ropes 11 and 12 and thus automatically changes the flexibility of the uprights 3 -6 load 24 depending on the magnitude of the dynamic load and stabilizes its oscillations. The connection of the ends of the ropes 11 and 12 with the axle 15 of the balancing trolley 2 allows, when reaching the outcrops of the unevenness with the wheels of the trolley, to reduce the tension of the ropes 11 and 12, increasing the flexibility of the pillars 3-6, and reduce the impact of the unevenness; conversely, the connection of the ropes 11 and 12 with the axis 15 prevents the latter from lowering into the cavities of the irregularities. Separate reserve ropes 11 and 12 and through the blocks. 7 and 8 racks 3-6, respectively, ensure the stable position of the load 24 with any distribution of inertial forces on the kennel of a large-sized product. Claim 1. Transport means for the transport of long loads, containing balancing trolleys carrying a frame with bypass blocks, sleeves rigidly attached to the frame, racks installed in sleeves with the possibility of vertical movement, in the lower part of which are fixed blocks, a pair of ropes, envelopes bypass blocks and blocks fixed on racks and saddles, characterized in that, in order to reduce the load of the transported cargo during transportation, it is equipped with a second pair of ropes, enveloping the bypass blocks and block Fixed to the uprights, the frame consists of an arch with the ends kronschteynami and saddle mounted on top of the rack, wherein between the saddles and the bushings are installed spring. 2. A vehicle according to claim 1, characterized in that the ropes at one end are attached to the frame brace, and the other to the axis of the balance trolley. 3. Vehicle on PP. 1, 2, characterized in that, in order to ensure the stability of the cargo in the transport position, each pair of ropes is stored through different blocks secured in the lower part of the uprights.
