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.

Known loading vehicle [1], taken as an analogue, containing a self-propelled chassis equipped with a winch, and a hydraulic platform rotary in the vertical longitudinal plane of the cargo platform in the form of a tipper body. 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 rope stored in a unit mounted on the front wall of the body, ensure loading piece 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.

Known loading vehicle [2], adopted for the prototype, containing a self-propelled chassis with a cab, a winch with a drive and a rope, a loading platform, a rotary hydraulic actuator in the longitudinal plane mounted on the skeleton of the chassis with the possibility of emphasis in the loading position in the supporting surface of the loading and transport means and made in the form of a tipper body with a bottom, front and side walls, moreover, a block is mounted on the front wall of the body, a removable truss equipped with a block at its free end and containing Menus provided with struts, the strut and the braces are rigidly secured to the side walls of the body, which in its middle part provided with reinforcement plates, and winch cable zapasovan consistently block the front wall of the body and the removable unit farm.

A disadvantage of the known truck is the increased height dimension when the transport position of the body, which limits the functionality of the truck, reducing, for example, throughput when driving under power lines.

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

The specified technical problem is solved by performing a removable truss with the possibility of installation in transport and loading position due to the fact that each rack of the removable truss contains two parts - the upper rotary and lower stationary - connected to each other by a hinge, the axis of which is perpendicular to a vertical plane passing through the longitudinal axis of symmetry of the truck, and is equipped with a locking device in the form of a rod installed with its hook-shaped bent ends in the rings, size mounted on the rotary and fixed parts of the rack on those sides that are facing the chassis cab, the hinge is equipped with a locking mechanism in the form of eyes mounted on the rotary part of the rack and on the strut, and a cylindrical pin, one end of which is equipped with a hat and the other hole to install the cotter pin.

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 rear view of the truck in the loading position with the emphasis of the tipper body in the supporting surface.

The loading vehicle contains a wheeled biaxial self-propelled chassis 1 of small capacity, on the skeleton 2 of which a cab 3, a winch 4 with a rope 5 are mounted successively, a hydraulically controlled load platform rotatable in a vertical longitudinal plane, made in the form of a tipper body 6 with a bottom, front 7 and side 8 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 are provided with reinforcing plates 13 in their middle part, the lower fixed parts 15 of the racks of the removable truss and struts 16 are rigidly attached by means of brackets 14, while the stationary parts 15 of the racks of the removable truss are perpendicular to the bottom of the body 6, and the struts 16 are tilted to the bottom of the body 6. The upper rotary parts 17 of the racks of the removable truss are connected to the lower stationary parts 15 of the racks by means of hinges 18. Each hinge 18 is equipped with a locking mechanism in the form of eyes 19 and 20 mounted respectively on the swivel th strut portion 17 and the auxiliary strut 16 and the cylindrical bolt 21 having one end provided with a cap, and another - for the installation of the pin hole.

At the free end of the removable truss with the help of the cross member 22, mounted on the upper rotary parts 17 of the racks, a block 23 is installed.

Each rack of the removable truss is equipped with a fixing device in the form of a rod 24 installed with its hook-shaped bent ends in the rings 25 and 26, located respectively on the fixed 15 and rotary 17 parts of the rack on those sides that face the cab 3 of the chassis 1.

The truck operates as follows.

Before loading piece or packaged goods, a removable farm is installed from the transport to the loading position. First, the rod 24 is removed, for which its bent ends are removed from the rings 25 and 26. After that, rotating the upper pivoting parts 17 of the uprights in the hinges 18, the geometric centers of the eyes 19 and 20 are combined, cylindrical fingers 21 are installed in the eyes, which are then cotter pins. The rope 5 of the winch 4 is stored sequentially in blocks 9 and 23.

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 removable truss also tilts to the supporting surface, ensuring the removal of the block 23 beyond the longitudinal dimension of the truck. The rope 5 of the winch 4, stored sequentially in blocks 9 and 23, 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 on a supporting surface with a load suspended on a removable farm, 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.

Before performing cargo and idling, a removable farm is installed from loading to transport position. To do this, first, the cylindrical fingers 21 are unfastened and removed from the eyes 19 and 20. Then, the upper pivoting parts 17 of the uprights are rotated in hinges 18 to the side of the cab 3 of the chassis 1 and the rods 24 are installed, for which their bent ends are introduced into the rings 25 and 26. The rope 5 winch 4 are stored in block 9 and the end of the rope 5 is placed on the bottom of the tipper body 6.

During the cargo and idling of the truck, the rods of the hydraulic cylinders 10 and 12 are extended and the tipper body 6 is in the transport position, and the removable truss holds the block 23 above the cab 3 of the chassis 1, which significantly reduces the height of the truck.

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 removable truss allows not only to pull a piece or tare load to the loading vehicle, but also to load onto another vehicle. The implementation of a removable farm with the possibility of installation in the transport and loading position provides, in the first case, a sufficient departure of the block at the free end of the farm beyond the longitudinal dimension of the truck, and in the second, a reduced height in height, which greatly expands the functionality of the truck facilities.
