Description

The invention relates to loading vehicles, mainly small-sized, and can be used for loading and transporting piece and packaged goods in farms that use small-sized mobile equipment.

It is known a truck adopted for an analogue, containing a chassis equipped with a winch, and a hydraulic platform rotating in a vertical longitudinal plane in the form of a tipper body [1]. The emphasis of the body on the supporting surface of the vehicle allows you to obtain a zero loading height of the bottom, and the inclination of the bottom of the body to this surface at an angle of 50-55 ° and the presence of a winch with a drive and a cable stored in a unit mounted on the front wall of the body, ensure loading of piece and stowed agricultural goods (bags, flasks, boxes, containers, etc.).

A disadvantage of the known loading vehicle is the inability to load goods onto other vehicles. In addition, the implementation of the loading operation by dragging piece and packaged goods requires large power consumption to overcome the friction forces of the goods on the supporting surface, can in some cases lead to undesirable contamination of the cargo and containers, as well as to reduce their safety.

It is known a truck adopted for a prototype containing a chassis, a winch with a rope, a loading platform, a rotary hydraulic drive in a vertical longitudinal plane and mounted on the chassis frame with the possibility of stop in the loading position in the supporting surface of the truck, a removable farm with a block on its free end [2].

A disadvantage of the known truck is low efficiency when working with small-tonnage agricultural cargo.

An object of the invention is to expand the functionality of the truck.

The specified technical problem is solved by the fact that the hydraulic platform of the truck is rotatable in a vertical longitudinal plane in the form of a tipper body with a bottom, front and side walls mounted on the chassis of the chassis with the possibility of stop in the loading position in the supporting surface of the truck at the same time, a block is mounted on the front wall of the body, and a removable truss is installed on the cargo platform by rigidly attaching it to the side wall Cams body, which are supplied in the middle part of its additional reinforcement plates.

The invention is illustrated by drawings, where Fig. 1 is a side view of a material handling vehicle with a tipper body in a transport position; figure 2 is a side view of the truck in the loading position with the emphasis of the tipper body in the supporting surface; figure 3 is a view a in figure 1.

The loading vehicle contains a two-axle wheeled chassis 1 of light capacity, on the skeleton 2 of which a cab 3 is installed successively, a winch 4 with a rope 5, a hydraulically controlled load-bearing platform rotatable in a vertical longitudinal plane, made in the form of a tipper body 6 with a bottom, front 7 and 8 side walls. Block 9 is mounted on the front wall 7 of the body 6.

The tipper body 6 is connected to the skeleton 2 of the chassis 1 by means of two multi-linkers (one on each side), each of which consists of a hydraulic cylinder 10, the body of which is pivotally mounted on the skeleton 2 of the chassis 1, and the rod is connected to the tipper body 6, and a two-arm lever 11 mounted pivotally on the frame 2 of the chassis 1, one arm of the lever 11 is connected to the tipper body 6, and the other shoulder of the lever 11 is connected to the skeleton 2 of the chassis 1 by means of a hydraulic cylinder 12. One of the sides of each multi-link is the underbody 6.

To the side walls 8 of the body 6, which in their middle part are provided with reinforcing plates 13, a removable truss 15 is rigidly attached by brackets 14, while the struts 16 of the farm 15 are perpendicular to the bottom of the body 6, and the struts 17 of the farm 15 are inclined to the bottom of the body 6. On the loose at the end of the truss 15, using the cross member 18, mounted on the uprights 16, a block 19 is installed. The rope 5 of the winch 4 is sequentially stored in blocks 9 and 19.

The truck operates as follows.

When loading piece or packaged goods, the rods of the hydraulic cylinders 10 and 12 are retracted and the tipper body 6 is in the loading position. The rear edge of the bottom of the body 6 abuts against the supporting surface of the truck, and the bottom of the body 6 receives a certain angle of inclination (50 ... 55 °) to the specified surface. In this case, the truss 15 also tilts to the supporting surface, ensuring the removal of the block 19 beyond the longitudinal dimension of the vehicle. The rope 5 of the winch 4, stored sequentially in blocks 9 and 19, is attached to the immersed piece or packaged cargo (not conventionally shown). By turning on the winch drive 4, the rope 5 is moved (winding onto the winch drum 4) and the load is lifted vertically to a predetermined height. With the subsequent operation of the hydraulic cylinders 10 and 12 (when pulling their rods), the angle of inclination of the underbody 6 to the supporting surface of the vehicle decreases, the trailing edge of the underbody 6 comes out of contact with the supporting surface. The truck receives the ability to move along the supporting surface with the load suspended on the farm 15, and, maneuvering the forward and reverse gears of the chassis gear 1, as well as the direction of rotation of the winch drum 4, delivers the load to a given point in space, including another Vehicle: trailer or truck. After the uncoupled piece or packaged goods are uncoupled, the described loading cycle can be repeated several times. If necessary, can also be carried out self-loading of the body 6 of the truck by piece or tare cargo, which is ensured when the body 6 is installed in the transport position.

When the vehicle is idling and idling, the rods of the hydraulic cylinders 10 and 12 are extended and the tipper body 6 is in the transport position, and the truss 15 holds the block 19 above the middle part of the underbody 6.

Self-unloading of the truck can be carried out by using the tipper body 6.

The economic effect is achieved due to an increase in productivity in the transportation of piece and packaged goods. Thanks to the implementation of the cargo platform in the form of a tipper body with front and side walls, reliable cargo retention on the platform is ensured during cargo movement and the self-unloading of the vehicle is simplified. The presence of a winch with a rope, blocks on the front wall of the body and the free end of the truss allows not only to pull piece or stowed cargo to the truck, but also to load on another vehicle, which greatly expands the functionality of the truck. Attaching the struts and struts of the removable truss to the side walls of the body significantly reduces the reaction forces perceived by the fastening elements, which allows to simplify their design and reduce the complexity of mounting and dismounting the removable truss, and reinforcing pads in the middle of the side walls of the body increase the reliability of the truss attachment.
