Description

The invention relates to the field of transportation of heavy and oversized cargo on land vehicles with container bodies with the possibility of loading and unloading in the field.

Known loading and unloading device of a truck (patent No. 67521, publ. 27.10.2007). The known device comprises a movable guide beam mounted on support rollers mounted on the head of the frame. At the end of the guide beam from the rear side of the car is fixed a means of lifting cargo with a grip. The frame is an inventory module in the form of a portal. The ability to remove and install the inventory module in the body allows you to transport piece and bulk cargo.

The disadvantage is the low reliability during loading and unloading in the field, in particular, due to the inclined position of the lifting device during the roll of the car body, and the limited use of the body area due to the inability to move heavy loads to its sides.

The prototype of the claimed device is a loading and unloading device of a vehicle with a box body (RF Patent No. 2031017, CL B60P 1/54, publ. 20.03.1995.). The device comprises a U-shaped guide beam in the plan, mounted with the possibility of longitudinal movement along the support rollers mounted on the ceiling of the van body. The drive carriage carrying the gripper is mounted on the supporting flanges of the I-beam profile of the guide beam through the running rollers with the possibility of moving along it. U-shaped in the plan guide beam allows you to cover most of the surface of the container body when moving goods.

The disadvantage of this device is the low reliability in the field. When a vehicle rolls with a box body, the I-beam also has an inclined position to the vertical. Because of this, under the influence of the weight of the load, the largest loads fall on the running rollers of one of the sides of the drive carriage, which leads to uneven loads and increased wear of the running rollers. In addition, a bending moment appears on the I-beam in the transverse direction from the eccentric load. The loading capacity of the loading and unloading device is limited by the permissible load on the roof of the box body, on which the support rollers are fixed.

The technical effect of the invention is to increase the reliability of the loading and unloading device when the roll of the container body of the vehicle with the provision of the movement of goods from anywhere in the area of the container body.

To achieve a technical effect in the loading and unloading device of a vehicle with a container body, including a movable guide beam equipped with a mobile lifting device, the guide beam is made of a two-link. The inner link of the guide beam is mounted on the support rollers inside the outer link and is equipped with a mobile lifting device, for example, a traveling hoist. The outer link of the guide beam is pivotally connected to the carriages that are mounted with the possibility of movement along the transverse beams mounted on the struts-supports.

Advantageously, the inner link of the guide beam is made in the form of an I-beam, and the outer link is made in the form of a split pipe.

The loading and unloading device is illustrated by drawings.

In FIG. 1 shows a general view of a handling device.

In FIG. 2 shows the connection node of the outer link of the guide beam with the carriage.

In FIG. 3 shows a cross-section of the guide beam along the support rollers mounted on the outer link of the guide beam, and the relative position of the guide beam and the carriage during the roll of the vehicle.

In FIG. 4 is a cross-sectional view along support rollers mounted on an inner link of a guide beam.

The loading and unloading device is placed in the container body 1 of the vehicle and includes a movable guide beam 2, made of a two-link (Fig. 1). The inner link 3 of the guide beam is made in the form of a beam with an I-beam profile and is mounted on supporting rollers 4 and 5 located inside the outer link 6 of the guide beam (Fig. 1, 3, 4). On the inner link 3 of the guide beam, with the possibility of moving along it, a mobile lifting device 7 is installed, for example, a manual mobile hoist with traction chains (Fig. 1, 3). The outer link 6 of the guide beam is made in the form of a split pipe and using pendants 8 is pivotally connected to the carriages 9 with axes 10 parallel to the longitudinal axis of the guide beam (Fig. 1, 2, 3). The carriages 9 are mounted on the transverse beams 11 with the possibility of movement along them. The transverse beams 11 are mounted on vertical struts-supports 12, which, to exclude the load on the roof of the container body, are fixed on the floor of the container body 1 with angles 13 and to the side walls.

When the roll of the container body 1 under the influence of the weight of the load, the guide 2 with the suspensions 8 rotates around the axes 10, while maintaining the horizontal position of the supporting shelves of the I-beam 3 (Fig. 3). This eliminates bending moment on the I-beam and ensures uniform load on the support rollers 4, 5 and the running rollers 14 of the lifting device 7, which increases the reliability and durability of the loading and unloading device.

Loading device, is used as follows.

In the transport position, the guide beam 2 is located at the side of the container body 1, and in the working position along the axis of the container body. The location of the crane beam at the side frees up space in the area of the front door, which provides the convenience of manual loading and unloading of light bulk cargo.

To bring the lifting device 7 to a predetermined place in the container body 1 during loading or unloading, move the carriage 9 along with the guide beam 2 along the transverse beams 11, determining the position of the load across the width of the container body 1, move the lifting device 7 along the I-beam 3 ( the inner link of the guide beam 2), determining the position along the length of the container body 1. To move the lifting device 7 outside the container body 1, the inner link 3 is moved relative to the outer link 6 guide beams 2.

Loading is carried out in the following sequence. The lifting device 7 is moved to the end of the I-beam 3, the latter is moved along the support rollers 4 and 5 in the split pipe 6. When the required extension of the beam 3 is reached outside the container body 1, the gripping device 7 is lowered to the load. Unloading is carried out in the reverse order.

Checks of the proposed device showed the reliability of its operation when the vehicle roll with a container body, as well as the ability to move goods from anywhere in the area of the container body during preliminary tests of it as part of the cargo module of a universal target training complex. The Russian Ministry of Defense assigned 9F6021 index to this complex.
