Description

The invention relates to equipment for loading long loads, including timber.

A device for loading long loads, such as timber onto a timber road train, consisting of a towing vehicle and a trailer-dissolution, including a hydraulic manipulator mounted on a car [1].

The disadvantage of this device is the complexity, and sometimes the impossibility, of loading large-sized timber onto a road train for the comel to place them on the conic of the car, and the tops on the conic of the trailer-dissolution and the inability to load timber at the top for placing them on the conic of the dissolution trailer.

The closest in technical essence to the claimed (prototype) is a device for loading long loads onto a timber road train, consisting of a mounted hydraulic manipulator on a tractor vehicle and a loading lever on a trailer-dissolution [2]. In this case, the loading lever is made of two parts, turning one relative to the other using an individual drive, consisting of three hydraulic cylinders. The disadvantages of this loading lever are the large weight commensurate with the weight of the mounted hydraulic manipulator; the need to control its three hydraulic cylinders, as a result of which the work of the loading operator is significantly complicated; significant width of the loading lever in transport position, which reduces the useful width of the trailer cone-dissolution.

The purpose of the invention is to simplify the design of the loading arm and control it, reducing the weight of the loading arm and reducing its width in the transport position.

This is achieved by the fact that the loading arm is triangular in shape and has upper and lower stops moving inside the guides. The guides have a longitudinal groove along which the loading lever is raised or lowered. The guides consist of two sections, and in the transport position the lower section is pushed into the upper and fixed in it with a locking finger. The lower section has additional removable stops to keep it upright during the loading of timber. The upper section of the guides has a transverse groove through which, when the lever is raised to its highest position, the lower stops come out and the lever turns over. The upper section of the rails is rigidly attached to the conic strut. Lifting the loading lever is carried out by a cable-block system and a winch mounted on the car. After the loading of the road train before the start of its movement, the loading lever is removed from the guides through the transverse groove or from below, so it is not necessary to reduce the useful width of the cone of the trailer-dissolution.

Figure 1 shows a device for loading long loads as part of a timber road train, general view; figure 2 - trailer-dissolution with loading arm, rear view; figure 3 - telescopic guides; figure 4 is a cross section of the upper section; figure 5 is a cross section of the lower section; figure 6 - loading lever, rear view; Fig.7 is the same side view.

The device consists of a towing vehicle 1 with a conic 2, a mounted hydraulic manipulator 3 and a dissolution trailer 4 with a conic 5 and a loading arm 6. The loading arm is raised and lowered along the telescopic guides 7 using a steel rope 8 and a winch mounted on the car behind the cab. For guiding the rope, blocks 9 are installed on the conic stance of the trailer-dissolution trailer. The guides consist of an upper section 10, rigidly attached to the stance of the conic 5, and a lower section 11. The lower section has the ability to slide into the upper section and is secured in it by a locking finger inserted into the holes at the bottom of the guides located in the side faces. The finger is fixed in the holes of the guides when the road train is moving with a special device. The guides have a longitudinal groove 12, as well as a transverse groove 13 in the upper part of the upper section. The inner part of the guides is hollow and has a rectangular cross-section 14. The stops are introduced inside the guides: the upper 15 and lower 16 of the loading lever 6. The loading lever can be inserted into the guides from below or through the transverse groove 13. The loading lever from the top has protruding parts 17 for holding loads on it and an opening or bracket 18 in the plate 19 attached to the side of the loading arm.

Before loading into the hole of the locking finger of the lower section of the rails, an additional removable stop is fastened with a spring bracket to fix it in a vertical position. An additional removable stop abuts the wheels of the trailer-dissolution.

The device operates as follows. The road train arrives at the loading point, is installed at the cargo stack, the loading device is brought into working position from the transport. To do this, the boom of the hydraulic manipulator mounted on the tractor vehicle is unfolded, its outriggers are lowered, a special locking device and the finger itself are removed from the locking finger of the guides of the loading lever of the trailer-dissolution, the lower section 11 of the guides is lowered, an additional removable stop is attached to it. The guides 15 and 16 of the loading arm 6 are introduced inside the guides, the loading arm is lowered to the lower position. The hydraulic manipulator 3 captures one end of a long load (timber) and lays it in the conic 2 of the truck-tractor 1. Then the hydraulic manipulator captures a long load, such as timber, possibly closer to the other end and drags it along the ground or along the lining log to the trailer 4 so that a long load, such as timber, is on top of the loading arm 6 between the protruding parts 17. A rope 8 is attached to the hole or bracket 18 of the plate 19 of the loading arm 6 with a hook 8. After checking the rights When laying the rope on blocks 9 with a winch, the lifting of the loading arm begins. In this case, the lower emphasis 16 abuts against the outer wall of the guides, and the upper emphasis 15 - against the inner wall attached to the conic strut. After the loading lever moves from the lower section to the upper front part of the lever, it rises upward relative to the rear due to the fact that the width of the cross-section of the hollow inner part is larger than that of the lower section. With further lifting of the loading arm, its upper stop reaches the extreme upper position and stops, and the lower stop at this moment leaves the transverse groove 13 of the upper guide and is turned over. In this case, a long load is thrown over the rack of the conic 5 of the trailer-dissolution 4. After that, the lower stop 16 of the loading lever is inserted back into the transverse groove 13 of the guides, the loading lever is lowered and the work process is repeated until the road train is fully loaded. At the end of loading, the loading lever 6 is removed from the rails to reduce the overall width of the road train and placed on the platform of the towing vehicle, an additional removable stop is detached from the lower section and also fits on the platform of the towing vehicle. The lower section 11 of the guides is pushed into the upper section 10 and fixed in it with a locking finger, into which a special locking device is inserted. The outriggers of the hydraulic manipulator rise, the boom of the hydraulic manipulator is transferred to the transport position.

The inventive device for loading long loads differs from the prototype in the design of the loading arm. This difference allows us to conclude that the proposed technical solution meets the criterion of "novelty." Signs that distinguish the claimed technical solution from the prototype are not identified in other technical solutions and, therefore, provide the claimed solution with the criterion of "significant differences".

The use of the inventive device for loading long loads allows us to simplify the design of the loading arm and its control, reduce the weight of the loading arm and increase the useful width of the cone of the trailer-dissolution by reducing the width of the loading arm in the transport position.
