Description

The invention relates to vehicles for the transport of long loads of annular cross section, such as reinforced concrete shells, used in the construction of bridge foundations. The purpose of the invention is to increase the safety of the cargo by uniformly distributing its mass and improving self-loading. FIG. 1 shows the vehicle, a general view; in fig. 2 - section of the central support with the mounted load; in fig. 3 is a section A-A in FIG. 2; in fig. 4 and 5 are embodiments of pneumatic chambers; in fig. b - view B on fig 2. The vehicle (fig 1) consists of t gacha 1, front 2 and rear 3 carts. On trolleys 2 and 3, install in frame 4 (not shown) frames 4, which can mix under the action of hydraulic jacks 5. T hach 1 is connected to the front bogie 2 by means of a trailer coupling 6. The front 2 and rear 3 bogies are interconnected centrally The support 7 (Fig. 2), on the ends of which the means 8 are fixed to the frames 4. The response means of attachment are made on the front carriage 2 on one side and on the rear carriage 3 g on both sides. Top 9 and bottom 10 chambers are rigidly attached to the central support 7 (Fig. 3-4). For some types of transportation and loading of tubular elements 11 with a level higher than that of the supporting surface, annular chambers 12 (Fig. 5) and chambers 9 and 10 of equal volume (Fig. 4) can be used. A self-aligning wheel 13 with an elastic treadmill is located on the lower surface of the rear end of the central support. The dimensions and number of pneumatic chambers are chosen depending on the diameter, weight and length of the pipes. To prevent movement of the load in the axial direction, folding supports 14 are movably mounted on the central support 7, which are provided with elastic pads 15 in contact with the tubular element 11. Fixation means 16 are provided on the supports 14 on the support 7. Inside the central support 7 there is a pneumatic main 17 with branches in corresponding cameras. The vehicle operates as follows. The rear carriage 3 is first fitted to the tubular element 11, having the same means of fastening on both sides of the frame 4. Then, the end of the central support 7 coupled to the rear carriage is disconnected, and the sliding edge 1 with the front carriage 2 and the foot approaches the element 11 from the other side. The stops 14 are in the folded position. In this case, the free end of the support 7 moves on the self-adjusting wheel 13 and rolls over into the tubular element 11. Thereafter, the free end of the support 7 is connected to the rear carriage 3. The stops-14 are laid out, pressed against the element 11 and fixed on the support 7. 8 pneumohighway 17 air is supplied. As a result of the difference in chamber volumes, the tubular member 11 is raised. When traveling by road train with significant irregularities, hydraulic jacks 5 can be used. Unloading is performed in the reverse order. The use of the proposed device allows to obtain a significant effect in the form of an increase in the safety of the transported cargo and an increase in the convenience of loading and unloading.
