(54) DEVICE FOR TRANSPORTATION OF LARGE-SIZE HEAVYWEIGHT CARGO

one

The invention relates to vehicles intended for loading, transporting and unloading large-sized super-heavy goods weighing more than 300 tons, and can be used in the construction of oil, gas, chemical and metallurgical, energy and other industries.

A device for in-plant movement of containers is known, comprising self-propelled trolleys with supporting frames on which a supporting frame is mounted, equipped with lifting mechanisms 1.

The disadvantages of this device are that, firstly, the frame is an open loop and for transporting bulky superfluid loads, the frame of this design must have a very large dead weight, secondly, a large surface area is required for container loading. maneuvering the device, which is economically unprofitable, but significant and impracticable; thirdly, this device does not have a bearing pad

for the installation of the container, which makes it impossible to transport on it non-rigid structures of a large mass.

It is also known a device for transporting large-sized tons of cargoes containing longitudinal beams, transverse beams connected to them and supported on carriages, carrying load-lifting devices 2.

However, this device is not enough 10 reliable in operation.

The purpose of the invention is to increase the operational reliability of the device.

This goal is achieved by the fact that the device is equipped with additional trolleys for supporting longitudinal

15 beams, a load platform for attaching to lifting devices and drive locking rods mounted on the longitudinal beams, with grooves at the ends of the longitudinal beams made for the ends of the transverse beams with holes for the said locking rods.

In addition, the lifting devices are power cylinders and rods fixed by one end on the longitudinal beams and connected by the other end to the load platform and to the load.

FIG. 1 shows the proposed device, side view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 is a section BB in FIG. 3; in fig. 5 — node II in FIG. one; in fig. 6 shows a section B-B in FIG. five; in fig. 7 - device in axonometry, in the loading position; in fig. 8 - the same, in the transport position; in fig. 9 is a view of FIG. 7; in fig. 10 is a view D in FIG. 7; in fig. 11 — node III in FIG. 9; in fig. 12 — node IV in FIG. ten.

The device for transportation of large-sized tons of cargoes consists of self-propelled vehicles — the main and additional carriages 1, on which the supporting frames 2 with axles 3 are mounted, which are included in the reciprocal supporting nodes of the hinge 4 of two longitudinal 5 and two transverse 6 beams. The longitudinal beams 5 have the gi 7 for the suspension of the loading platform 8 with the load 9 in the transport position. The loading platform is fixed to the struts using an axis 10 and a latch 11. To lift and manipulate cargo 9, as well as to lift and lower the loading platform with elongated axles 10, the longitudinal beam 5 is equipped with power cylinders 12, illuminated to beam 5 at the help of the brackets 13, which ensures the swing of the power cylinders during overload. In addition, on the longitudinal beam 5, the fixing rods 14 are driven by the power cylinders 15 for fixing the transverse beam. The transverse beams 6 also have tapered ends 16 to facilitate entry into the slots L on the longitudinal beams.

The device operates as follows. Before loading, the power cylinders 12 are connected to the lifting units of the loading platform 8, and the rods 7 are released from communication with the loading platform, for which the clamps 11 and the axles 10 are removed. Thereafter the loading platform 8 is lowered by means of the cylinders 12 the ground and power cylinders 12 are disconnected from the lifting units of the load platform. The load platform 8 remains lying on the ground, and the power cylinders 15 draw the rods 14, thereby uncoupling the transverse beams 6. To complete the preparatory operations, the trolley 1, on whose support frames the longitudinal beams 5 are mounted, turns 90 ° and simultaneously dismounts, as a result which remains on the cargo platform 8, lying on the ground, and two transverse beams 6. Next, the carts transport the transverse beam 6 to the loading place.

When loading, the trolley 1 with transverse beams 6 approaches from the front sides of the load, and the longitudinal beams 5 on the trolleys 1 are brought in from the lateral sides. When this occurs the entry of the tapered ends 16

transverse beams 6 in the grooves A of the longitudinal beams 5 with further fixation.

Thus, a supporting frame is formed. Next, the power cylinders 12 engage and lift the load to a height greater than the height of the loading platform, and the supporting frame with the raised load is mounted with the help of carriages 1 above the loading platform, moving parallel to the ends of the load. After sliding over the loading platform, the power cylinders 12 lower the load 9 onto the loading platform 8 and the cylinders 12 are coupled to the lifting units of the loading platform, after which the loading platform rises together with the load installed on it, further

the loading platform is attached to tam 7, for which axles 10 with latch 11 are inserted, all the trolleys are rotated 90 ° in one direction and begin to move the cargo on a common command by radio. When unloading, the device stops near the prepared place for the permanent installation of cargo, the cargo platform 8 is disconnected from ton 7 and the cargo platform is lowered to the ground and the cylinders 12 are moved to engage and lift the cargo. The loading platform remains on the ground. Next, cargo is transported to the place of its permanent installation on a previously prepared foundation and lowering the cargo onto the foundation, followed by cylinders 15

5, the rods 14 are pulled out, freeing the transverse beams 6, after which the trolleys 1, on the support frames 2 of which the longitudinal beams 5 are mounted, turn 90 ° and travel at the same time, and the remaining beams 6 with their self-propelled vehicles are taken away from the load and delivered to the location of the cargo platform. At this point, the connection of the longitudinal and transverse beams occurs, as described above, the lifting and securing of the loading platform, and the device is ready to go back for the next load.

The expected annual economic effect from the application of one proposed

.J devices in the Minneftegazstro system will be about 200 thousand rubles.
